Dear Creator,

I'm excited to see whatever you're creating for me! Time travel is one of my favorite tropes of all time, and I'm equally fond of scenarios where characters do and don't replace themselves.

DNWs: porn or animal cruelty

Worldbuilding: How does time travel fit into the universe established by canon?
I'm a big fan of general worldbuilding as well - the underlying political structures of a society, more in-depth looks at a historical event, how technology works, all that stuff that's just off screen.
Alternate divergent timelines, whether good or bad
Characters making a concerted effort to change their past and that accidentally setting off the butterfly effect

Fullmetal Alchemist: Brotherhood & Manga

Maes Hughes (FMA:B), Olivier Mira Armstrong (FMA:B), Riza Hawkeye (FMA:B), Roy Mustang (FMA:B), Edward Elric (FMA:B), Winry Rockbell (FMA:B)

Accidental Time Travel To The Past - In the "older consciousness in younger body/character replaces themself" model of time travel, I'm curious what any of these characters would do if they woke up in the past. Would they try to change anything?

Would Ed decide not to attempt human transmutation? If returned later, would Ed refuse the military commision?
Could Roy or Riza or Maes or even General Armstrong avert or mitigate the Ishvalan Civil War if they tried? Would their attempts potentially accelerate the conflict?
What would General Armstrong try to do? Why?
What would Winry try to do? Would she prevent Ed and Al from attempting human transmutation; if so, could she succeed?
How would foreknowledge affect the promised day?

Meeting Currently Dead Character in Past - Anyone travels back, whether accidentally or on purpose, and runs into Maes Hughes. Awkwardness results, particularly because Hughes doesn't understand why people are acting so weird around him.

Meeting your much younger self - Time travel of the "character does not replace themself" variety. I'm particularly interested with this trope with regards to Ed, Roy, and Olivier, whose younger life we know little to nothing about. With the context of the future, how does the character view their younger self and their actions? (How does their younger self view them?) Do they offer their younger self any advice? Does their younger self follow it?

Outsider POV Of Strange Events Caused By Time Travel/Outsider POV Of Time Traveler(s) - In most time travel stories, only a select few characters have traveled back (either with intent or without it), and it's always interesting to see how their actions look from someone "not in the know." Because Hughes would be dead if the point of departure is past the Promised Day, he seems like the obvious candidate of the requested characters, but it would also be fun to have Random Soldier #3 (or Random Ishvalan #12, Who May or May not Be Scar) view the actions for characters altering the timeline of the Ishvalan War, or Ross/a member of Mustang's team's viewpoint. (Or Olvier gearing up at the wall with either the Briggs soldiers or Roy being the outsider POV.)

Time Travel Fix-It - Altering Canon or Backstory - What is says on the tin. A few examples:

Ed seeking to prevent himself from committing human transmutation or to save his mother's life in the first place somehow.
Winry seeking to prevent Ed from committing human transmutation or her parents from dying.
Literally anyone seeking to prevent the Ishvalan Civil War.
Literally anyone seeking to prevent Hughes' death.

How do(es) the character(s) seek to accomplish this? (If the character replaces themself, they have to act normal and adjust to lower level of resources/are a literal child; if they don't, they have no resources at all.) Are they successful?

Time Travel Fix-It - Canon is the Fix - The Promised Day relied on a lot of factors coming together: the conspiracy had to be known, allies had to be gathered, massive sacrifices had to be made to take down Father and the Sins (specifically, no one else could fill Van Hoenheim's role). What happens if one of those fell through? or more?
Maybe, in addition to the reversal circle, Scar's brother's notes contained a last-resort method of time travel via crossing the gate so that everyone ends up on take 2 (and 3, and 4, and...).

Time Travel to Past to Discover You Can't Change the Future - The classic tragic trope. (Again, especially involving Hughes' death, but I'm down for anything.)

Trying To Change The Timeline By Preemptively Killing Someone/Trying To Change The Timeline By Saving Someone - All of our heroes have gone back into the past to stop the Promised Day. They have... differing opinions on how to accomplish that.

Who opts for murder? (Are there any surprises there, e.g. Winry going after Kimblee?) Who do they think needs to be killed? (Is it just one person or Bradley's entire cabinet?) Do they make the murder obvious or not?
Who opts for saving? (Any surprises there, e.g. Olivier deciding that the best way to prevent it is to save this one specific person.) Who do they save? (Is it a single person or a larger-scale action like preventing the Ishvalan Civil War?) How?
Are either of these attempts successful?

The 39 Clues - Various Authors

Group: Thomas Cahill & Katherine Cahill & Luke Cahill & Jane Cahill, Amy Cahill, Dan Cahill, Sinead Starling
Note: I am fine with Group: Thomas Cahill & Katherine Cahill & Luke Cahill & Jane Cahill appearing in a group or separately, though it would be interesting to contrast their reactions to similar events.

Character Acquires Time Manipulation Superpower/Artifact Unexpectedly - The serum includes the ability to time travel if you do [arcane thing], or Gideon had another invention, or Sinead invents something.

Does the character time travel deliberately/do they have control?
What do they do with this ability?
Do they seek to change something? If so, what are they trying to change? Can they change it?

Can send text messages back in time/Communicating with the Past/Future Through Letters - I'm interpreting these tags more broadly as not only incorporating text communication but also audio or even video if you so choose. I use "pen pal" in the questions below as a general term only.

For Dan or Amy, I'd love to see them communicating with their parents or Grace (perhaps when they were at a similar age if via letters, or the AJT messages are actually sent through time if via text message). For Sinead, it would be interesting to see her contact either her pre-Clue Hunt self or some mentor from the past (maybe a younger, much less polished Alistair?). For Thomas/Katherine/Luke/Jane, contact with some of their respective descendants would be best. Of course, it would also be interesting to see messages from a future self, especially from an alternate timeline.

How does the character react to the messages? Do they realize the messages are from the past/future? (For Thomas/Katherine/Luke/Jane, there might be issues with their descendants speaking modern English rather than Elizabethan; for Amy, Dan, and Sinead, slang might be a clue.)
Do the conversations with the past influence their decisions in any way? (For Sinead specifically, could this maybe lead her to make different decisions with regards to the Vespers?) Do the conversations with the past influence choices the characters in the past make?
What concepts transfer well across time? Which really don't? Can the character understand their pen pal's motivations; if not, does understanding develop over time?
If the character knows their pen pal in real life, when does the realization of who they are hit?

Meeting Currently Dead Character in Past - I'm down with this being anyone. Bonus points for the dead character has no idea what is going on.

For Thomas/Katherine/Luke/Jane, it would likely be Gideon (or maybe even an earlier relative like Madeline the Matriarch?); I'd be interested in how their reactions to seeing their dad alive again differed, especially if they're in their younger bodies but serum-augmented personalities moved with the shift. (For example, would Luke be more itnerested in getting the full serum whereas Katherine might want to investigate the source of the fire? Would Thomas' main reaction be to punch out Luke because he believes he set the fire? What would Jane do?)

For Dan, Amy, and Sinead, anyone who died during the course of the books is fine. Some suggestions:

Hope and Arthur - This would be a real heartbreaker for both Amy and Dan, especially if they can't avert the fire (or do avert it only for their parents to die anyways).
Grace - This one would get real interesting because Dan and Amy (and quite possibly Sinead, because so was Jonah) were quite attached to her, but they also know she hid a lot of stuff from them that did damage in the long run, particularly since the mansion burned down after her death. A pre-death confrontation (either with them replacing or not replacing themselves, since Dan looks like Fiske and Amy like Hope) would be fun.
Alistair - Another master at the game, but one all three are very attached to for longer. This would probably be the best scenario for Sinead.
Isabel - I don't think any of them would want to have a conversation with Isabel, but they might consider her more convenient when dead.
Natalie - Any or all of them could harbor guilt about her death, but if they go back to before the Clue Hunt, she is an utter brat.

Time Loop/Groundhog Day - Escape by Achieving Mission - For Thomas/Katherine/Luke/Jane, the loop is the night of the fire. Possibly with a later start point so they can really start to hate each other beforehand, but Thomas and Katherine versus Luke and Jane for the first iteration would also be good. The mission is either to save their father's life, avert the fire entirely, or to kill Damien Vesper.

For Dan, Amy, and Sinead, the Gauntlet acts as a time loop; once the representatives of the five branches enter, they either make the serum and unify the family, or they all die of non-homicide causes, at which point the loop is cancelled. The scars of the failed attempts are when previous groups tried to blast their way out of the loop. (Whether Grace knew this or not is up to the author.)

I am My Own Grandfather - It's noted that Dan looks very much like Fiske and Amy looks very much like her mother, who looks EXACTLY like Madeline (the Madrigal). In a non-replacement universe (possibly with the Dan or AMy coming from a bad timeline), they are one and the same.

Time Travel Fix-It - fixing one's own mistakes - After death, the character goes back in time to before their regrets. They make different choices. (Well, try to. See altering canon or backstory for ideas.)

Time Travel Fix-it - Multiple Characters Trying To Fix Different Things - And, as a result, nothing gets fixed/things do NOT go according to plan.

For Thomas/Katherine/Luke/Jane, they're all sent back to before the fire; maybe Olivia, Gideon, and/or Madeline (if we're doing non-replacement) are sent back too. They all have different objectives: save their father/stop the fire, get the serum, find out who set the fire, keep the family together, kill my brother, etc. If any of these objectives are actually completed, it's entirely uninentionally.

For Dan, Amy, or Sinead, they go back to the Clue Hunt, possibly with Ian, Jonah, Hamilton, Ted and Ned, Nellie, Fiske, etc. Some groups are still set on winning, Sinead mostly wants her brothers to come out uninjured, Dan and Amy are scrambling to get the Madrigals onto a war footing for CvV when they're not supposed to know about the Vespers yet, and everything is going to hell directly in a handbasket. Bonus if only Dan or Amy comes back and one has to work around the other.

Time Travel Fix-It - Altering Canon or Backstory - Some ideas:

Prevent the 1507 fire and subsequent breakup of the Cahill sibling.
Failing that, prevent the giving of the serum (clues).
Prevent the Trent fire.
Prevent the explosion that injured Ned and Ted.
Prevent the rediscovery of the serum.
Prevent the deaths of Irina, Lester, Alistair, Natalie, Pony, etc.

Bonus points if the timeline is flexible/this doesn't work as intended (e.g., Trent fire doesn't happen, so Hope and Arthur are assassinated a week later) and if the butterfly effect kicks in (e.g., Irina never dies, so Isabel goes to jail for a variety of other crimes because Irina has access to the incriminating evidence).

Outsider POV or Time Travelers - Their clothes are wrong, they're acting funny, they've just killed innocent socialite Isabel Ka- wait, what was in her basement?

Harry Potter - J.K. Rowling

James Potter, Lily Evans Potter, Group: James Potter & Severus Snape, Sirius Black

Note: I know canon goes for a "timeline can't be altered" model of time travel, but feel free to break that as you wish, or to incorporate it for maximum tears.

Accidental Time Travel To The Future - Either to the Harry Potter Generation or to the Next Generation.

How do Snape and Sirius react to their future selves if they meet? How do James and Lily react to them?
When do they discover their fates? How do they react?
How do they react to Harry's generation/the Next Generation? (These kids are the kids/grankids of people they know, and half of them are the orphaned children of teenagers who are still, in their minds, very much alive.)
When/if they travel back to the past, do they work to change their fates? Are they successful? (If not, is it due to imperfect information or flexible timeline inevitability?) Do they manage to change anyone else's fates?

Accidental Time Travel to Past - I could see them going to their personal pasts (wake up at death/fall through veil to their time at Hogwarts) or to the past for them, either of which could be fun.

If character goes to personal past, do they seek to change their actions there? Why or why not?
If character goes to the past, does the situation there inform their present (e.g., limits of fidelius, universal antidote to avoid death, protective charms, how to become animagi, etc.)

Communicating with the Past/Future Through Letters - Mostly, I'm interested in forward communication with Harry's generation, especially Harry. (Though Hermione would also be interesting, as would Luna, as would a first-year Ginny.) How does the communication affect the character and their pen pal? When do they learn the communication is across time as well as space? When does the character learn about their eventual fate/the fate of the Potters/the end of the war?

Enemies Travel Back In Time Together - forwards in time also works. Obviously, this applies to Snape & James, but Lily & Sirius (and Lily & James, depending on when the fic is set for them), would also work. They hate each other's guts, but they're not here on purpose, and they really need to get back home...

Hunger Games Series - All Media Types

Group: Katniss Everdeen & Peeta Mellark, Katniss Everdeen, Primrose Everdeen, Rue (Hunger Games), Cinna (Hunger Games), Finnick Odair, Haymitch Abernathy, Group: Katniss Everdeen and Johanna Mason

Butterfly Effect - Character Tries to Prevent Other Character's Death

Any of the victors travel back to their games with the intent of not winning (or at least, not winning alone). This either ends in rioting or a no-winner year.
Someone travels back in time to take Prim's name out of the reaping bowl. Effie either draws Katniss' instead (killing one of her instant likeability factors) or draws a random stranger's, who quickly dies off. (I can't remember if Rory was 12 in the first book and could afford not to get tessera because of the hunting or not, but if so, his name could be pulled from the male bowl, and Gale could volunteer, becoming an extraordinarily grumpy face of the rebellion.)
Katniss, (Plutarch), and Haymitch conspire to get Cinna out of the Capitol alive. This has... unintended consequences. (Cinna doesn't get along with Coin, consequences in the arena, Plutarch dies instead, Katniss as a more willing Mockingjay, etc.)
Katniss (and Peeta) go back with the intention of Rue being the one getting out of the 74th Arena. If successful, this completely fucks up the Rebellion, since the Mockingjay is dead.

Meeting Currently Dead Character in Past - Cinna, Rue and Finnick are the obvious choices here if the time traveller is coming from the book timeline, but it could be anyone if the time traveller is coming from an alternate timeline. I'm mostly interested in how the traveller and dead person interact; is the dead person's fate averted? Are they informed of it? If we're going with the replacement model of time travel, do they figure out their friend is a time traveller?

Time Loop/Groundhog Day - Escape by Achieving Mission - The arena (or a part of it) acts as a time loop until there is one victor.

This could be a fun take for an alternate Third Quarter Quell - every day is the exact same, complete with opponents (seemingly) rising from the dead. (They might be replaced with murderous mutt replicas - the victor of victors is the last one left unreplaced.)
For Peeta, Katniss, and Rue, some part of their arena repeats - perhaps from the day of the announcement, perhaps the last day, perhaps all of it - until there is only one victor. Up to the author whether the competitors manage to break the loop or not.
For Johanna or Haymitch, something goes wrong during the original run of their arenas, so reboots have to be made.

Time Travel Fix-It - Altering Canon or Backstory - Either the Capitol attempting to erase the Mockingjay narrative/Rebellion, the requested characters "fixing" their mistakes/what should have happened in their arenas, or someone trying to tidy up the Rebellion. How successful are these attempts?

Time Travel Fix-It - Canon Is the Fix - There is a timeline where Haymitch drinks himself to death before the 74th Hunger Games, where Peeta isn't called as Katniss' co-tribute, where Katniss fails to become the Mockingjay or is never reaped, where the rebellion splutters out because a different card is drawn for the Quarter Quell, where... this is someone's attempt to fix that timeline.

Time Travel Leads to Dystopia/Time Travel Makes Things Much Worse - See "Butterfly Effect" above.

Trying To Change The Timeline By Saving Someone - Who needs to be saved? (Is it a single person, a splinter rebellion group, or a general "I'm trapped fifty years before my time, might as well save whoever I can?") Why? How does the character aim to accomplish this? Are they successful? Does this work?

H.I.V.E. series - Mark Walden

Otto Malpense, Natalya | Raven, Maximilian Nero, Theodore Pike, Group: Otto Malpense & Laura Brand & Shelby Trinity & Wing Fanchu

Abusing Time Travel For Petty Reasons - Especially Otto & Laura & Shelby & Wing or a younger Max (and Diabolus Darkdoom). What is the most ridiculous thing done with time travel? By whom? Why? ("Because I wanted to" is a perfectly logical answer for some of these characters.)

Character Acquires Time Manipulation Superpower/Artifact Unexpectedly - A (sometimes erratic) time machine seems like the thing Professor Pike would invent and then have Nero or Raven accidentally use, but a fun take would also be Otto & Laura & Shelby & Wing building one for funsies or Shelby just having one from her days as the Wraith that she loans out occasionally.

Alternate Timeline - Good character now bad - The Disciples are the time travelers (or some seriously weird butterfly effect goes on), and the Bad Timeline and ours collide. Go as campy or as serious as you want with the Bad Timeline versions of the "good" guys. Some possible ideas:

Otto was kept under closer watch instead of being dumped at the orphanage and is truly eeevil. Cue Significant Haircut/Scar, because the eeevil clones have Significant Eye Color Change already.
Raven was never turned by Nero and is still a pet assassin/assistant of the Furans. (By implication, Nero and possibly Diabolus Darkdoom, and therefore Nigel, are dead.) Her happiness with this situation is up to the author, and she may be turned to the side of the (relative) good when put in contact with her alternate self.
Raven still murdered Nero (and maybe Darkdoom) and then murdered the Furans to become her own evil supervillain.
Max, burned by Elena's death, burns all his ethics and decorum and becomes eeevil. (Again, noted by Significant Haircut/Scar.) May still run (a more eeevil version of) H.I.V.E. (which is, of course, staffed by eevil versions of the current professors.)
Professor Pike, instead of (or in addition to) being in lack of safety protocols, is also in lack of scientific ethics.
(For relative values of "bad") Laura, instead of going to H.I.V.E. or to jail (as anticipated), is recruited by [top secret cybersecurity force].

I'd also be down with the Bad Timeline versions of eevil characters (Trent, Cypher, the Furans) being erstwhile allies.

Time Travel Fix-It - Canon Is the Fix - There is a timeline where Otto was unable to defeat Overlord at various points (either due to premature death or being in the wrong place or not knowing how), knowledge of Overlord came too late (Max was killed/Cypher actually died at the end of Overlord Protocol), or other things generally didn't work out. What happened in that timeline?

Trying To Change The Timeline By Preemptively Killing Someone/Trying To Change The Timeline By Saving Someone - Everyone agrees that they need to prevent the clones from happening in order for the world not to end. Everyone agrees the simplest method of this involves time travel.

Someone thinks they should prevent Overlord in the first place by murdering its creators/whoever sugggested the project in the first place. (Nero, who oversaw the project, backs away nervously.)
Someone thinks they should save the Overlord techs (like Wing's parents) so that they have more people to think up a back door when the time comes.
Someone thinks they should save Lucy Dexter because surely her power of persuasion would influence the clones.
Someone thinks they need to find the labs and destroy them themselves to ensure no clones survived.
Someone thinks they should just kill Number One right after the Overlord Incident, before the cloning project can start. (Otto, a clone, laughs nervously.)

Steven Universe (Cartoon) (Fic, In-Universe Meta, Art)

Any or No Characters, Lapis Lazuli, Bismuth, Rose Quartz, Original Character(s)

Rose's Rebellion

How/why did the rebellion start? Was it inspired by other revolts against Homeworld? Did it inspire other revolts against Homeworld?
What tactics were used by either side? What role did humans/the natural environment play in the fighting?
What types of gems were on both sides? What were their reasons for staying loyal/rebelling? How did this influence strategies? (E.g., the rebellion focusing on guerilla raids because of their smaller numbers but being more successful because they had more heavy hitters/better weapons because of Bismuth, Homeworld initially losing because its forces on earth were mostly technicians working on the Kindergartens)
The rebels/ a Homeworld squad/group just before/during the corruption
The Corrupting light - How was it made? What besides Rose's shield stopped it? Did any other gems survive the light intact? Is there any way to reverse it? Had it been done before
What were the goals of both sides at the start of the rebellion? How and why did they change? (Did Homeworld shift from a quick silencing of dissent to complete obliteration of Earth? Did Rose become more radical as the rebellion progressed?)
Who killed Pink Diamond? Why? What was Pink Diamond's stance on the rebellion, and was it constant or changing as the rebellion progressed?

Rose's Tears

How do they work? Are their effects permanent, or do the effects on chronic conditions (such as Connie's eyesight but not Greg's leg) wear off eventually?
Where did they come from? Are they a trait Homeworld introduced to rose quartzes? Do all roze quartzes have them or just our Rose Quartz (and Steven)? Is the trait shared in any form by other types of gems?
How did Rose Quartz discover their powers? How did she use them during the rebellion?

Gems' Influence on Earth

Effects on the land - Why is there a sea where Siberia is supposed to be? Did the Kindergartens significantly affect Earth's geology/the distribution of minerals within Earth's crust? Why is the geography so different?
Effects on ecology - How did the Kindergartens affect species distribution? Were some species wiped out? Conversely, did others survive (longer than they would have otherwise) because of Homeworld interference? Did the Homeworld occupation or Rose's Rebellion cause any population bottlenecks (including in humans) that radically altered evolutionary development in that species?
How did Rose's Rebellion (and earlier Homeworld occupation) affect religious systems and mythology? How did it affect the formation/distribution of political states? (Art idea: a temple or political map)
Gem technology - Did it speed up technological development in some areas of Earth? How is it interpreted by later archaeologists/anthropologists?

Fort Briggs

Who was the Briggs Fort Briggs is named after? What did they do?
The assorted commanders of Fort Briggs
Has the fort always been at its current location or has it moved according to the border with Drachma? If it was originally further south, how and when was it built, and where was it originally? Has it ever been further north than it is?
When and how was Fort Briggs originally built? How has its design been changed over the years?
How has the relationship with Drachma changed over time? How has Fort Briggs responded to this?
Since Fort Briggs is so cold, a special alloy is needed for any metal in contact with skin. Would this also apply to other metal objects continually exposed to the elements, such as tanks and cannons? If so, how did they develop the necessary alloy, and where is the alloy/the objects made?
A day running Fort Briggs

International Perceptions of Amestris

How does it vary by country? (Ex, more positive in Xing, which is a tourist destination, versus Drachma, which is at quasi-war with Amestris) Is there propaganda about Amestris in the other countries?
Are there immigrant communities in Amestris? Do they influence perception of Amestris in their home countries?
Are there Amestrian expatriate communities in surrounding countries? Why did they leave? How do they influence perception of Amestris?
On a similar note, are there any communities of Ishvalans who escaped the genocide in other countries, particularly Xing (and maybe Aerugo)? How do they affect public opinion? Do they move pack after the Promised Day?
What news surrounding events in Amestris is received by other nations? How true is it? What do people living outside of Amestris hear about the Promised Day?

Political History of Amestris

What was the area of Amestris like pre-Amestris? Do the current state/province lines reflect pre-Amestris kingdoms/coalitions of states? How did they vary in different areas of the country? Did they have a unifying characteristic, either regionally or nationwide? (Art idea: a map showing the area before Amestris as a state formed, or a progression of maps showing its formation)
How much of Amestris (particularly the North and the East Areas) was/is inhabited, and
Where did "Amestris" start? (Did it originally start in Central or was that picked as a capital later on?) What was its military like before its expansion? Did any areas join willingly or was it all through military conquest?
How does the age of Amestris compare to the nations surrounding it, particularly Aerugo, Creta, and Drachma? (Since Xing is separated by the large desert that was once Xerxes, it's slightly less important with regards to this question.) Did it form at around the same time or is it like modern Germany, forming much later? If it formed significantly later, how did its military fight other countries so effectively?
Was the military dictatorship element present from the beginning or did it develop later on? If it wasn't an element of Amestris at its founding, how did it come about, and who lead Amestris before the (presumed) coup?

The 39 Clues - Various Authors (Fic, In-Universe Meta, Art)

Any or No Characters, Original Character(s), Gideon Cahill

Madrigal Interference

How did attempts to keep any branch from assembling the serum affect history? (Did it precipitate any wars, policy decisions, conspiracy theories, etc.?)
It's mentioned that the Madrigals were not above assassination to keep the serum formula from being rediscovered. Who did they kill? How close were they to success? How effective was this tactic? (Side note - were some of the murders committed by Vespers to sow chaos?)
On a less depressing note, many humanitarian organizations were created/are run by Madrigals. Were these responses to bloodshed caused by other branches? Did any non-Cahill reform movements and reformers receive funding from the Madrigals/get integrated into the Madrigal network? Do any of these act on occasion as covers for Madrigal operatives?
Other attempts to reconstruct the serum - When did they happen? Who was involved? How did they fail?

Covert Operations

Spying on other branches - Since Thomas, Katherine, Jane, and Luke dispersed fairly quickly and fairly widely, when did this start as a practice? Was useful information gained? How much of it was direct surveillance versus small-scale clue hunts?
What attempts at spying have worked? Which have gone horribly wrong? (How have they gone horribly right?)
The most ridiculous mission in Cahill history, complete with strange covers and stranger developments.
Technologies developed to spy on other branches, from the useful to the absurd (and of varying usefulness).
What kind of cover have been used for covert operations? Have any of them been successful?
Creative methods of concealing information
How did the clue hunt influence the development of intelligence/counterintelligence strategies and technologies?

Technology

What technologies were first developed as part of the clue hunt? How long did it take for them to be introduced to the general world? Are there still some hidden from the public?
Some Cahill inventions are great. Some are a bit strange. Some are just plain weird.
Irina's poison nails - who thought they were a good idea? What is the learning curve involved? What are the (non-obvious) drawbacks?
Development of poison - were poisons developed specifically for the clue hunt? Were they originally found in nature or synthesized? Did any of them (or their delivery methods) leak into the general world? In general, how did the clue hunt influence the development of medicine?

Development of the Serum - I know that the point of the serum was to facilitate an international adventure and not to make sense for a man in early sixteenth-century Ireland to create (either in concept or in ability to obtain ingredients), but I persist nonetheless.

How did Gideon decide the ingredients he needed? How did he obtain them? (Most notably, if you're living in 1507 regardless of place, how do you get (and then, presumably, purify) uranium? Was the stuff in the original serum just pitchblende?)
How did Gideon create the serum? What equipment/processes did he use?
Did Gideon realize the serum would be poisonous? If so, why did he test it on himself anyways? Do any/some of the negative side effects carry on to the branch serums? (And if so, are these effects also present by inheriting the serum or just by drinking it directly?)
Attempts to reverse engineer the serum, with predictable results
Supposedly, the serum was originally meant to be a treatment/vaccine for plague. Considering one of the defining traits of canon is "every famous historical figure from the seventeenth century forwards (and several from the sixteenth century as well) is a Cahill", what would have happened if Gideon had actually created a workable treatment/vaccine for plague instead of the serum?
Alternatively, Olivia Cahill's adventures to create a serum antidote, particularly because a young Madeline would almost definitely be tagging along.

Gender of AIs - H.I.V.E.mind and Overlord are both decidedly male, but H.I.V.E.mind mentions a female AI he'd gathered information from. What determines gender in AIs? (Is it something in the source code or part of the emerging personality?) Are there any AIs that don't have a gender?
Development of AI technology - Why did G.L.O.V.E. decide to develop an AI in the first place? How did they figure out the resources/equipment/knowledge needed? Were there failed attempts pre-Overlord?
Was there any cause for Overlord's insanity? How is the possibility of a murderous AI guarded against?
Who (besides G.L.O.V.E.) has AI technology? How are they used?

History of H.I.V.E.

Locations of H.I.V.E. - It was originally in Iceland and was moved when knowledge of its existence was leaked to the outside world, and I think the H.I.V.E. Raven is at during the flashback sequences might be in a third location. How were these bases built? How were they kept secret? Were there any other locations of H.I.V.E.?
Where did Nero get the idea for H.I.V.E.? How did he gather the first class of future villains?
How has the organizational structure of H.I.V.E. changed over the years? Were streams present in the beginning? What courses were offered?
How did the assorted staff come on board? (How do you hire teachers for a school that doesn't exist?) Were any of them there from the beginning? Are any of them former students?

Technology

Cloning - How were Otto (and the others) made? How were the computers in their heads implanted? How did the process affect their development? How do the implants give the clones their powers, and are there any abilities yet to be discovered? Do the implants have any vulnerabilities (blocked by a Faraday cage, hackable, etc.)?
Ms. Leon - How did Professor Pike develop something that would swap her and her cat's minds? How long did it take to develop the collar so that she could speak again? Are the prototypes/blueprints for either of these still around? (If so, that's an ample opportunity for hijinks to occur).
Medical Technology - Even besides the cloning, medical tech seems more advanced than the tech in our world; Colonel Francisco's prosthetic hand is more advanced than most (if not all) prosthetics today, and it's at least a few years old. There's also the ability of several characters to come back from near-death entirely unharmed. What kind of healing technology exists in the H.I.V.E. world? How was the medical knowledge (particularly in neurology) developed? What other areas of medicine are affected? Is the medical technology widespread knowledge or limited to G.L.O.V.E./the criminal underworld?
Animus - How was it developed? Why? How was it made nonlethal to normal humans? Is there any left in-univers after the end of Zero Hour? Does it have any long-term side effects? (The first generation is lethal extremely quickly and causes extensive damage as it replicates, and the second generation is readily visible in blood and affects nerve tissue/the brain; there's got to be some side effects to that)

Hunger Games Series - All Media Types (Fic, In-Universe Meta, Art)

Any or No Characters, Cinna, Cecelia, Original Character(s), Original Gamemaker, Original Victor

Resources and Manufacturing - Essentially, how is stuff made and where did the raw materials come from?

We know that coal comes from 12 and stone is mined in 2, but where is the Capitol getting its metal? (Are they recycling old metal objects, mining new ore somewhere, or a bit of both?) Where are plastics being produced? (And where is the oil needed to make said plastics coming from?)
For cloth - are cotton and/or flax grown in District 9 and/or 11? Does "livestock" for District 10 include sheep (for wool)? Where is leather processed? What about synthetics? What about silk, where the producer of the raw material is not native to and probably wouldn't survive the climate of Panem?
District 13 is mostly underground, in hiding from the Capitol, and in a relatively cold climate. Where is their food supply coming from? What about their clothing? (I assume they get energy and heat from nuclear power.)
How does the manufacturing technology of Panem compare to manufacturing processes today? (Is it like the early Industrial Revolution, running on coal and water power? Is it mostly mechanized or is it labor-intensive? How do the technologies involved compare?) Has this changed since the Dark Days?
How do these influence the manufactured goods available to the Capitol and the districts?

Fashion

I'd love to see a fashion magazine for In-Universe Meta.
Are there materials constraints? (Limited supply of certain fabrics/dyes, supplies we consider commonplace being scarce/nonexistent, etc.) In contrast, are there techniques/fabrics that don't exist in our world that are commonly used in Panem?
How have fashions changed over the years? Is there anything like a "vintage" movement attempting to bring old styles back? (If so, what counts as "vintage"?)
Where do trends come from? About how quickly do they change? Are there separate subcultures within the Capitol, and what are they like?
Anything exploring the crazy body modifications of some Capitolites - Which ones are in vogue? How do they change from season to season? (What kind of lifespan to trends like implanted gems or dyed skin have?) What do you do when yours goes out of style? How is the full-body dying (like Octavia's) achieved, and is it permanent? What kinds of cosmetic surgery are available, and how popular are they? Is there any sort of removal process?
Hair styling - How common are wigs? How do Capitolites create their crazy hairdos? What kinds of hair dye do they have? What colors and styles are in vogue?
Makeup - How do Capitol cosmetics compare to modern ones? Is there a wider range of foundation colors due to the skin-dying trend, or do people who dye their skin have to color foundation themselves or do without? How does a Capitol citizen attempt to achieve a "natural" look? Are there any really crazy makeup trends?
Painful side-effects of the above - toxic makeup, botched surgery, anything from the disturbingly long and varied history of dangerous/fatal fashion… (shocking cover stories for Capitol gossip magazines)
Fashion in the games - Have victors ever created trends? Who gets to design for the games? Are the stylists more or less permanent or is it a rotating cast of questionable fashion? What were the most questionable clothing decisions, either for the interviews or during the parade? Who designs the outfits the tributes wear into the arena? Who makes them? (If they're made in Eight like the rest of Panem's clothes, has anyone in Eight ever figured out the arena before the games?)

Arena Design

Who designs the arena? How are they picked? Who has oversight over the design?
How are the arenas constructed? What technologies are used, and who are the laborers involved?
How has arena design changed over the years? What has stayed the same?
What are the most popular arenas? Why?
A day running the arena

Education

How does education vary by district?
What's school like in the Capitol? What do they learn about the districts? What is emphasized, and what's left out?
Is there higher-level education available? If so, where? How do you apply? Is it available for anyone or only Capitolites/citizens of select districts where advanced education is necessary? What's it like?
How is history handled? What kind of primary/secondary sources are available? How do the documents available influence education, especially about more modern history like the dark days?
Is there a centralized educational department? What are the standards/guidelines it sets, and how are they measured/observed? (Is there some form of testing? Is it only really checked up on in certain places or if things have clearly gone wrong?)
Where do the teachers come from? (The Capitol? The district where they teach? Another district?) How are they accredited? What level of control do they have over their curriculum?

District 8

What kind of jobs are available? (Cutting out/sewing garments? Spinning thread? Weaving/knitting fabric? Treating pelts/leather? Embroidery?) How are they assigned? How mechanized are they? What are the potential dangers, and are there any safety protocols?
How is the relationship between District 8 and the Capitol? They're making most of the clothes for the districts, but do they also make clothing for the Capitol? Are citizens from 8 able to find work with stylists/fashion designers in the Capitol? (If so, do they end up stuck working in the games? Are there limits on what they can work on/how long they can stay in the Capitol?)
Woof and Cecelia's Games - What were their costumes like? What were their arenas like? How did they win?
How did the rebellion in Eight form/spread?

The Rest of the World

Where are the other settlements? What are they like? Did they also form totalitarian states? What level of technological development do they have?
How do outside forces affect the rebellion? (Do they provide resources to either side?) How does Panem affect other settlements/countries?
Interactions with Panem - Can they see Panem's broadcasts? (Alternatively, can Panem see theirs?) What is their opinion of the games? How is their knowledge of Panem limited by the propaganda on Panem broadcasts? Do refugees from Panem interact with outside communities?
Off on a tangent, but I imagine that people in some of the larger districts (particularly ones with woods like 7) who needed to disappear wouldn't always risk the trek up to District 13, especially with the convenient nearby wilderness. Have these people formed settlements of their own? How did these affect the rebellion?

Quarter Quells

Who wrote the quell cards? What are on some of the others? Does Snow actually pick the one designated for that year or pick whichever one suits his interests? Are they just created as needed with the rest of the envelopes blank?
What did the first Quarter Quell look like? How was the voting carried out? What was the arena like? Who won? How?
How do the Gamemakers prepare for the quarter quell without knowing what it is? Are they given hints about adjustments to the arena they have to make? Have any Gamemakers figured out the "twist" based on these hints?

First Hunger Games

How were the tributes chosen? Were they still picked "at random" or were children of rebels singled out? Were escorts sent out to the districts, or were some districts still too dangerous? Who were the tributes?
What parts of the pre-games events were present? How did they differ from the pre-game events in Katniss' games? (I'd love to see the parade or interviews from this games.)
What was the arena like? What was its environment like? Was it simpler than modern arenas? Was there a sponsor delivery system?
Who won? How did they do it?

Tributes

How is the reaping managed in other districts where it isn't feasible to gather everyone in one place? (Are there preliminary reapings? Do they pull names beforehand? Is one subdivision of the district picked to have either half or all of the reaping?)
Careers - How do they train? (Is their training focused solely on combat? Are they taught how do play to the cameras? Is there any discussion of what happens after they win?) How does this differ between 1, 2, and 4? What are the procedures around volunteering?
What were their lives like before the reaping?
Reactions to the Capitol - How do different tributes deal with the stress of the pre-games week? Who's most/least impressed by the technology on display? Who's surprised by the food/waste of the Capitol?
Surprising victories - Who was never expected to leave the arena alive? How did they win? On the other hand, which tributes were expected to win but suffered embarrassing deaths - drowning in a shallow pond, accidentally poisoning themselves, getting labyrinthitis and falling off a cliff, etc. - instead?

Victors

Talents - How many victors actually have talents (instead of faking one like Katniss does in Catching Fire)? What sorts of talents do they have? How do victors pick their talents? What counts as an "acceptable" talent? Are there any surprising talents?
How do the different victors interact? Are there "cliques" (former Careers, older victors, industrialized or rural districts, etc.)? Do victors communicate across district lines?
I really enjoyed the interactions between victors and their commentary about the games in Catching Fire, particularly Johanna complaining about her costume during the parade. I'd love to see more of that, either during the quell or in a normal year.
Mentoring - How do mentors cope with losing tributes? (Is it easier for them to die in the bloodbath, never really having a chance, or have them almost make it? Does having another victor to trade off responsibility with, either year to year or within a games, make grieving easier or harder?) What advice do different mentors give their tributes before the games? Besides advice and supplies via sponsors, what role do mentors play in the games?
AU where the quell is different - How do the surviving victors influence the rebellion? Do they ally themselves with District 13 or not? Do they star in propos? Are any of them leaders like Lyme? How does the greater number of surviving victors affect Coin's proposition of one last hunger games?

Harry Potter - Books 1-7 (Fic, In-Universe Meta)

Original Character(s), Any or No Characters

Hogwarts secret passages

How many passages are there? Do they all date back to the founders or have some of them appeared at a later date? Is there any pattern to the secret passages or moving staircases?
The creation of the Marauders Map
Room of Requirement - What purposes has it been used for over the years? What are the limits of its transformation (size, detail, supplies inside, etc.)?
Passages out of the castle - Which ones do Filch know? How did he find them? Where did the mirrored passage lead to before it caved in? How did it cave in? Are there any no one knows about?

Use during wartime - The secret passages to places outside of Hogwarts could function as an escape or invasion route, and the ones inside the castle could act as a place to hide. Were any of these used by Dumbledore's Army during the Second Wizarding War?

Handicrafts

What kind of handicrafts do wizards make? How do they differ from the muggle versions? (Different patterns/techniques developed after the Statute of Secrecy, different materials used, etc.)
What kind of automation is available via magic? Are the results comparable to similar projects done by hand?
Are handicrafts ever enchanted? What sort of enchantments are available?
Does the ability to magically create hotter/more stable fires affect the qualities of metal (particularly alloys) and blown glass produced?
Stored magic/enchantments (like the shield scarves) - Do they do this better from the witch or wizard who made them? Do the materials matter? Does the production process matter?

Harry Potter - Wizarding World (Fic, In-Universe Meta)

Any or No Characters, Original Character(s)

Music

Music Theory - For meta, I'd love to see sheet music or a music theory text. How do notational conventions differ? (Do the markings in sheet music mean different things for wizards and muggles? Are there some notations that only exist in either wizard or muggle music?) Did wizards invent a different version of the staff? Do they use different scales and base their music around that? Are the stylistic conventions different? What elements does magic add to music?
Classical Music - How does it differ from muggle classical music? Was there crossover of stylistic elements between the two? Who were the great magical composers of the time?
Choral Music - Who are the major choral composers, both in the past and currently? How do muggle and magical music differ? A lot of choral music, particularly the more modern stuff, uses the text of poems; what wizarding poems are used? (Are any muggle poems used? If so, are they ones about witchcraft or just poems the composer liked?)
Magical Operas/Operettas/Musicals - How do the topics covered/genres differ? What are the famous magical operas/operettas/musicals? Have muggle operas/operettas/musicals ever crossed over? (How popular were they? Did they ever become codes like Scottish rugby?) Who are the big names? What are they known for? How do conventions in music differ between the muggle and magical versions? What techniques are shared with/differ from the muggle versions? How does magic influence the kinds of productions done? How does magic influence the cost of doing a production? Are there any famous theaters/theater areas in the magical world, and do they have any kind of awards system? Who are the famous performers? Are any of them creatures (like sirens) or squibs?
Modern Music - What genres are popular in the wizarding world? Who are the most popular bands/performers? Do any of them have squib members? How does magic affect the music produced? How are concerts arranged? (Have any really lost muggles appeared at wizard concerts? Did they like the music?) Have any muggle groups ended up really popular in the wizarding world? Have any magical groups ended up with a muggle following?
Music as spells - How does singing affect the power of a spell? Does the spell need to be sung to a specific tune? (If so, does they key matter? What happens if it's sung to a different tune? What happens if it's sung off-key or slightly off the tune?) What happens if you flub the words? Are there spells without words where only the tune matters?

Musical Instruments

Are there any musical instruments that only exist in the wizarding world? What sounds to they make? What makes them magical?
Spell aids - I'd imagine these would mostly deal with timing, though auto-tuning spells and a spell equivalent of a pitch pipe/piano app probably exist. What kinds of metronome spells are there? How do they work? How accurate are they? Can they be programmed to do the timing of duples/triplets/etc.? Are there ones that count out measures, either aloud or into performers' heads? (Do these actually convince people to count?)
Self-playing orchestras - How does the sound compare with music played by live/human orchestras? (Does it sound more robotic? How do dynamics compare?) How are instruments enchanted to self-play? How are all the different parts coordinated? Does this technique work on all instruments, or is it difficult/impossible to perform on certain instruments? (If so, why? Is it a materials thing? Is it a complexity thing?) How are self-playing bands/orchestras conducted?

News media

What are the major magical newspapers worldwide? What are there reporting styles like? Do they only report on magical events or is there some coverage of muggle events as well?
Standards of reporting - What are they? How do they differ from those in the muggle world? How do they vary from paper to paper and across the world?
Meta idea: reports on major events (e.g., either of the wizarding wars, or maybe something more lighthearted like the Quidditch World Cup) from different sources. How do they differ? What common traits do they share?
Is there a magical equivalent of the internet? How does it affect the spread of news and/or misinformation? How does it differ from the muggle internet, and how are the two similar? Is it an extension of the muggle internet (with a special type of connection/domain ending)?
News radio shows - Besides the lack of images, I'd imagine this is the closest equivalent to muggle TV. What new channels exist on the wizarding wireless? What issues do they cover? How well do they cover issues?

Libraries

Cataloguing - What system(s) do wizards use to catalogue books? How are books with magical properties (like The Invisible Book of Invisibility or Monster Book of Monsters) classified?
Where are magical libraries located? How do wizards get to them? How are they protected/regulated by the Statute of Secrecy?
What kind of overlap to magical and muggle libraries have? Is there some overlap (particularly with fiction) between the two? Are there logistical similarities (e.g., interlibrary loans, holds, magical library cards)?
What functions of a library are made more difficult by magic? Which are made easier (e.g., theft prevention, self-shelving charms, self-return charms)?

39 Clues, Harry Potter, Big Hero 6 (fusion or crossover, art or fic)

39 Clues/Harry Potter - These are two of my favorite canons of all time, both for the possible extents of their worldbuilding. (Plus, the chaos alone would be fantastic to watch.) How does magic interact with the serum? How does magic shape the clue hunt? Alternately, how does the clue hunt shape the magical world?

Characters are Cahills - Which branch do they belong to? How closely are they tied to that branch? How does this affect their personal relationships?
Magic and the Cahill serum have a history of clashing. (Muggle-repelling wards don't quite work, Cahills mistake magic for other branches' sabotage, witch hunts as an excuse to kill rival branch members, serum has magic properties, etc.)
The Clue Hunt goes to Hogwarts/magical Britain (most likely due to weirdness in Into the Gauntlet). Hijinks ensue.
Harry Potter characters get involved in the Clue Hunt. Hijinks ensue.

39 Clues/Big Hero 6 - This is mostly for the chaos factor. (Also because, superheroing aside, Big Hero 6 characters are more or less well-adjusted members of society and 39 Clues members mostly... aren't.)

Characters are Cahills - Which branch do they belong to? How closely are they tied to that branch? How does this affect their personal relationships?
Starlings at SFIT - Maybe the Starlings are family friends with one of the students, or one of the triplets decides to go there for school, or they need a new piece of tech for reasons. Hijinks ensue.
The Clue Hunt goes to San Fransokyo. Hijinks (and fire) ensue.
Big Hero 6 characters get involved in the Clue Hunt. Hijinks ensue.

Harry Potter/Big Hero 6 - I love it when magic meet/clash in fiction, mostly for the chaos that ensues, but I could also see a version of Clarke's Third Law going on; Big Hero 6's science is assumed to be/actually magic (or magic is assumed to be advanced tech by Big Hero 6).

Hermione spends some time in San Fransokyo for reasons. (Gap year? Magical exchange program? Boredom?) Hijinks ensue.
Harry is somehow related to the Tamadas. He's not sure what to think of his relatives, but they're certainly nothing like the Dursleys (or anyone else he's met, for that matter).
Magic AU - Honey Lemon is a Potions mistress, Baymax is some sort of golem, Wasabi is working on automated cutting charms, Gogo is trying to make the world's fastest broom
The Horcrux hunt leads to San Fransokyo.

Fullmetal Alchemist, Steven Universe, Nancy Drew (crossover, art or fic)

Fullmetal Alchemist/Steven Universe - Mostly for the inevitable chaos, but also because some of the characters meeting would be very interesting (and quite possibly hilarious).

Gem shards can function as philosopher's stones. (Alternately, philosopher's stones have some level of consciousness and can become a gem.)
Izumi and/or Olivier meet the Crystal Gems (During the Rebellion, on Earth, or in Amestris - I don't really care as long as warrior women get to do some possibly strange bonding.)
Maes isn't quite sure how he ended up in this pink plain, but at least he has someone to talk (and show pictures of Elisia, she's three now, isn't she just adorable) to.
Homeworld invades Amestris. People prepare to fight.
Ed and Steven switch places, either via bodyswap (Steven's mind in Ed's body, and vice versa) or random universe switch. Chaos ensues.
Lapis' mirror turns up in Ishval. Maybe she finds this miserable planet actually likable; maybe Ed fixes her gem via alchemy and she goes back to homeworld. Regardless, chaos ensues. (Lapis' power would be somewhat limited due to lack of nearby water, but it still wouldn't end well for anyone who annoyed her.)

Steven Universe/Nancy Drew - Nancy is used to some weird things happening around her, but Beach City takes that concept a bit too far.

The mystery ends up leading to the Crystal gems even though it's seemingly unrelated.
Nancy trying to get anything out of Reynaldo
Nancy making very logical, sound deductions that are completely wrong because gems are involved.

Nancy Drew/Fullmetal Alchemist - Nancy gets more than she bargained for when she investigates a mystery in Amestris.

A seemingly benign case leads to something much bigger (i.e., animal cruelty ends up with Tucker, anything ends up with the Promised Day)
She wasn't even in Amestris for a case. (A la Captive Witness, she ends up involved in chaos for purely circumstantial reasons.)
Maes Hughes was a friend of her father, and they're covertly investigating his death.

Fullmetal Alchemist/Big Hero 6 (Crossover or fusion, art or fic) - For the SCIENCE!!!

The State Alchemists as grad students at SFIT
Big Hero 6 gets dumped into Amestris. Hijinks ensue. (Especially if the State Military is freaking out over the new tech).
Honey Lemon learns alkahestry and/or alchemy. Superhero fights in San Fransokyo get a little more interesting.
Ed nerding out with Big Hero 6.
FMA AU - Big Hero 6 are all alchemists or Mustang's team (with Tadashi as Maes)

Competent characters being competent

Mysterious Benedict Society - Kate Wetherall, Milligan, Constance Contraire
Four exceptional children must take on dangerous missions to defeat a villain! As a former GT kid who spent way too much of elementary school reading under the desk, I found the main characters very realistic and relatable. I also enjoyed the puzzles presented explicitly and implicitly in the text that you got to think over along with the main characters.
This canon is three longish books, but they're all very quick reads. Spoilers for the end of book one and Constance's development in book three.

Constance - I'd love to see how she changes as she grows up.

Her powers - Do they get stronger or more consistent as she grows older? Do they get less taxing because some of the exhaustion was because she's so young/still at an age where she'd need naps regardless of magic mind powers? Do the side effects of overextending herself get worse as she gets older even if she does it less frequently?
Growing up with Mr. Benedict - What's her education like? (Does she continue to be homeschooled? When/if she goes to school, how does she deal with being the smallest/youngest due to probably skipping grades? Is it very focused or often tangential? How regular is it?) Which adult is her favorite and why? Are there any security incidents due to escaped/never captured allies of Mr. Curtain?
AU where she was successfully sent to LIVE - how does that change her personality? Does she behave/perform better or worse? Does she still meet and/or bond with Reynie, Sticky, and Kate?
Her poetry - any shape, any form. Does she branch out in insulting style? Does she make some that isn't insulting?
Crossover option - Constance is somehow related to Otto from H.I.V.E. Hijinks ensue.

The Wetherall Family - I love the bond between Kate and Milligan in the books, especially the way their outlooks clash but they both keep supplies on hand to be prepared for any eventuality.

I'd love to see how Kate and Milligan reconnect after the first book; they've both spent the past decade or so basically alone, and Kate has some pretty big abandonment issues at times in the first book. Is Kate wary of him leaving again at first? Is Milligan worried that he'll mess something up?
Their normal life - Cue some silly domestic fluff. What's Milligan's job like? How is Kate doing in school? (How does the school administration deal with the Wetheralls, raptors, spies, and all?) How does Moocho fit into it? Do they ever go see Kate's circus?
Milligan meets Moocho - I view Moocho as sort of Kate's Replacement Dad when she was at the circus. How does Milligan react to him? Do they share stories? How does Moocho end up living in their house? (I could see Milligan and Moocho as either in a relationship or as platonic partners in child-rearing.)
An AU where they met differently - Maybe the orphanage sends Kate to LIVE instead of letting her join the circus, or maybe she doesn't respond to Mr. Benedict's ad, or maybe his subconscious recognizes Kate in the circus posters, or any number of other things lead to Kate and Milligan meeting at a different time/place. How does this change their relationship? Would the appearance of a younger Kate act as a trigger for Milligan's memory?
I'm also curious about Kate's mother; is she actually dead or "merely departed"? What was she like before her death/disappearing? How did Milligan meet her? (Personally, I wouldn't be surprised if it involved Milligan getting seriously injured.)

Milligan - the perpetually injured secret agent man

Background - when did he become a secret agent? Why? Why does he have the farm house? Did someone take care of it or was it in disrepair when he returned there?
What were his missions beside the one to Nomansan Island like? Did any of them go south?
What were his coworkers like? How do they react to him coming back?
After the end of the first book, does he have all of his memories back or is he still missing some? Did the brainsweeping have a permanent effect on his memory?

Kate - I love all the characters in this series (even the villains at times), but Kate is my personal favorite.

What was her life like in the circus? What were the other performers like? What sort of hijinks did she get up to?
How does she adjust to normal-ish life (going to school, having a parent around, etc.) after the first book ends? Does she join any school clubs? Does she make friends?
Her relationship with Madge - I really, really liked Madge in the second book, especially Kate's "I've got a pet that can easily peck my eyes out! Stroke her feathers, they're so soft!" attitude. How did Kate get Madge in the first place? (Was she a rescue of some sort?) Has Madge ever saved Kate?

39 Clues - Any
A wide variety of characters travel on a dangerous journey to win an ultimate prize! The various characters work both with and against each other, and while most of them know what they're doing (or, at the least, what they're doing it for), the two main protagonists, Amy and Dan, don't have a clue. (On rereads, watching Amy and Dan stumble through the Clue Hunt is pretty funny.) I really liked the wide variety of both areas and degrees of competence the cast displayed, and I found the inclusion of adult characters (of varying motives and alliances, some of whom didn't end up dead nor evil) refreshing. The history and locations included (mangled as they probably were) were also interesting.
This series is probably the hardest to obtain; it's a lot of (very short) books by many different authors. The prompts are primarily based off the first series (which is 11 books long), but there are spoilers for the second series in the "Sinead" section.

Crossover/Fusion option - Characters from another fandom (I don't care which) are Cahills. Hijinks ensue.

What branch are they? How strongly/exclusively do they display their branch's trait?
How loyal are they to their branch - are they staunchly loyal to their branch leader? For the idea of the branch but not its leadership? A Madrigal/Vesper? Out of this mess completely and glad of it?
Incidents where they meet and clash heads due to being Cahill agents
39 Clues characters (Grace, Arthur/Hope and kids, the Holts, the Starlings, branch heads, etc.) are mutual acquaintances/enemies
Something gets set on fire. (It's the Cahill way, after all.)

Historical Cahills - The bits of (probably inaccurate) history were one of my favorite parts of the first series. In short, every major figure in the past 400 years (and a significant portion in the century before that) is a Cahill. All of them. Even the ones who have no ties to Europe (let alone Ireland) in the slightest.

What branch are they? How are they related to the Cahills?
Do they have any contact with other Cahills?
What kinds of missions do they take on?

Fiske - AKA The Man in Black. I like the way he interacts with Amy and Dan and am curious about his decision to go completely off the map.

Life before disappearing - did he ever do Cahill business? Was their one inciting incident to his disappearing act? If so, what?
Relationship with Grace - How did it change when he went into hiding? How close were they when they died? Were there boundaries they had with regards to each others' missions that they didn't have elsewhere?
What did he do as the Man in Black? - missions (gone horribly wrong/right), protecting agents, attempted recruitment, checking up on people (Hope & Arthur, Grace, old friends, etc.)
Relationship with Hope - Were they in contact? Did he stay away to keep attention away from her? Did she know his identity? Were there any times when they got to act like normal family members?
Relationship with Amy - In Storm Warning, Amy sees Dan in Fiske; did Fiske have a similar experience with Amy and Hope (or Grace)? How did the first few month after the Clue Hunt go? (Misconceptions Fiske had about dealing with two teenagers, misunderstandings, general awkwardness, etc.) Is there anything he keeps from her (and Dan) that he wouldn't have kept from Grace?

Grace

Relationship with Fiske - How did it change as they grew up? (In Vesper's Rising, she's practically raising him; does this continue as he gets older? How does their involvement in Cahill affairs change how they interact?) How did it change when he went into hiding? How does it affect the missions they take and their decisionmaking in regards to each other? In Storm Warning, Amy sees Dan in Fiske; did Grace see it the other way around?
Relationship with Amy (and Dan) - I love how their perception of her changes through the series. How did she balance preparing them for the Clue Hunt (teaching Amy to research, training Dan's memory, etc.) with keeping them from the Clue Hunt? (Did she try to do a similar thing with Hope?) Why did she think sending them to live with Beatrice was the best course of action? (An AU where she raises them more directly would be appreciated.)
Missions - We got hints of this in the books, but no incidents besides the one in Vespers Rising are ever explicitly shown. (Though, considering that one's her first, it explains a lot about Dan and Amy's decisionmaking processes.) What kind of reputation did her missions have within the Madrigals, in the general Cahill community, and within the Vespers? How was it earned? Reckless stunts (that may or may not end well), more careful/delicate things (that are easy to fuck up), managing agents in the field instead of being the field agent for the first time, etc.

Amy

Books - What are her favorites? Why? When has her knowledge from books (e.g., extinct languages, animal care, ancient history) unexpectedly come in handy?
Readjusting to normal life after the Clue Hunt - not for long, obviously, but how did it go? Any awkward moments?
Relationship with Dan - I found their relationship as siblings (they love each other, but they have major differences in their though processes, and those sometimes come out as yelling) very realistic. How do they cope with all of the insanity they've gone through? What's their "normal" life like? Sibling bonding moments would be great.

Nellie

Relationship with Amy (and Dan) - What were they expecting her to be like based on past experiences with au pairs, and how did she fulfill/subvert them? How long has she known them?
Training - How aware was she that it wasn't "normal" afterschool activities? What was the extent of it? Were there any areas she excelled/failed dismally at?

Alistair

Backstory - Did he ever go on Ekat missions? How did he get his limp? How did he know Hope/Arthur?
His burrito's - Where did he get the idea? (At random? Wishful thinking while on mission? Fight with Bae Oh?) Did any of the Ekats (eventualy) react positively to it? (Maybe it meant better rations for a mission or they just thought the science was cool.)
Relationship with younger Cahills - He acts as an honorary uncle to both the triplets and Amy and Dan, and I find that great. (Especially since there isn't a tragic backstory involving children behind it.) It's also clear that he ends up taking care of the Starling triplets after the Hunt is over; why? Does he bond with other teenaged agents or just the Starlings and Amy and Dan?

Sinead

Life before the Clue Hunt - What was she learning? What were her (potentially nonexistent) parents like? Did she and her brothers spend a lot of time with Alistair?
Relationship with her brothers - What do they fight over? What do they bond over? How did they pull themselves back together during the Clue Hunt?
Time as a Vesper - How did she join them? (Did she seek them out or vice versa?) Why? What did she have to do to join? Was her time at Cahill manor part of a mission?

William McIntyre

Past - What kinds of missions did he take? How much trouble did he get in? How did he meet Grace?
Relationship with Grace - He was her most trusted advisor (and her lawyer/executor), but they also clashed heads occasionally. What did they fight about? Were their occasions where she didn't follow his advice?
Cahill Legal issues - a lot like normal legal work, just with some more fire and murder.

Irina Spasky

What kinds of missions did she go one for the Lucians? Did any of them go wrong?
Her family - How did she meet her husband? How did he die? Was Nikolai's death really an accident?
Poison nails - Who came up with the idea? What was the learning curve involved like? (e.g., poison nails stuck into inanimate objects, poison nails stuck into her, poison nails breaking, poisons nails leaking...)

H.I.V.E. series - Diabolus Darkdoom, Nigel Darkdoom, Maximilian Nero, Theodore Pike, Laura Brand, Shelby Trinity
Four teenagers at a school for villains have hijinks-filled adventures! While the trouble Otto and/or Co. get up to is definitely engaging and fun at times, I also have a soft spot for the older generation of baddies. I love the way this series alternately abides by, lampshades, and subverts assorted action tropes, the "I may be a supervillain/design evil lairs/occasionally threaten to kill the protagonists, but I have standards!" that most of the adults play totally straight being my favorite example.
This series is currently eight books long, all written by Mark Walden, and there are spoilers (particularly but not exclusively for the backstory bits) up through Deadlock, the eighth book. I'd also personally recommend skipping the first book; in my opinion, the second serves as a much more engaging jumping-off point.

Diabolus Darkdoom

Past - How did he become a villain? How did he meet Nero? What were his evil plans like? Why does he have a much better relationship with Nero's dad than Nero does?
On/Off Villainy - He's pretty infamous within G.L.O.V.E. (and has an MI6 file), but Nigel didn't know he was a villain until he was sent to H.I.V.E., and it's strongly implied his wife didn't know, either. How did he maintain this illusion? Were there any occasions when he had to switch roles rapidly?
Relationship with Nigel - I find their relationship after Diabolus comes back completely adorable. Anything with these two interacting would be amazing. ("Bring your kid into your plot" day pre-series? Many, many hospital bedside interactions? Nigel dealing with Diabolus' death only to learn he's alive?)
Him and His Toys - if giant, invisible transport and weapons count as "toys." Has he always been a huge tech nerd? When did his tendencies towards "anything you can build, I can build better" start? How did he build the Dreadnought and the Megalodon while he was in hiding?

Dr. Nero

Backstory - How did he meet Diabolus? How did he join G.L.O.V.E. (While Diabolous has hints of a life outside villainy, Nero doesn't; did he start out in G.L.O.V.E. because of his dad?)
Elena - Who was she to him? What was her relationship to the Furans? What happened to her?
Day-to-day running of H.I.V.E. - just like normal school, but with more explosions
Evil Plans - While Nero is pretty much the definition of Lawful Evil (well, Ethical Evil), he had to have done something to earn him infamy. What?

Professor Pike

Scientific experiments that went horribly wrong and/or right - He's a mad scientist who has turned one of his coworkers into a cat and (accidentally!) used a superlaser to punch a hole through the school. What other experiments make Nero want to pull his hair out?
Relationship with Nathaniel - Again, everyone else has a better relationship with Nero's dad then Nero does. How did these two meet? Do they have Old Men Who Are Done with This Nonsense get-togethers?
Relationship with his students - He's not very good safety supervision (see: Violet, the laser incident), but he does like them. Do his students like him? Do they understand what he's talking about? Does he help them with their more dubious projects (like he gave Shelby the flash drive in Deadlock)?

Laura

Her computer skills - Where did she learn them? How? Did her parents know about them? When have they come in handy?
Relationship with her family - They're all great. (And, besides Laura, likely to never appear again, but they're still great.) She loves them, they love her, but she's not allowed to go home to see them under threat of imprisonment. How do they cope? Does Douglas ask about his older sister as he grows up? When she graduates from H.I.V.E., does she go to visit them? Have either have her parents done something mildly villainous before?
Schemes (possibly with the rest of the gang) that go horribly right.
Future - What kind of work does she do? How successful is she as a villain? DOes she teach computer science/electronic security at H.I.V.E.?

Shelby

The Wraith - How did she become the Wraith? Why? What is the craziest thing she did to make a heist work?
Backstory - Where did she come from? What was her family like? Did she leave anyone behind when she went to H.I.V.E.?
Schemes (possibly with the rest of the gang) that go horribly right.
Future - Does she return to heists or does she do something else? Does she teach physical security at H.I.V.E.?

Nigel

Relationship with his father - It's very adorable. How did he cope with Diabolus' "death"? What (mis)adventured did they have before said "death"? Do they have (mis)adventures after he comes back?
Future - I can see this going one of two ways; he'll either turn out as a well-adjusted and mostly legal member of society, or he'll set loose plant monsters on an unsuspecting public. (The plant monster comes from the first book.) Which happens? Why? Is his father proud (and slightly scared) of him?

Number the Stars - Peter Neilson, Lise Johansen, Annemarie Johansen, Ellen Rosen
A girl must smuggle her best friend out of Nazi-occupied Denmark! I found this book very heartwarming, and I loved the way that Annemarie is both sheltered from and painfully aware of the reality of the situation at different times.
This canon is probably the easiest to pick up; it's one very short book.

Lise

Her life in the resistance - How did she join the resistance? (Via Peter or some other means?) What kind of ops did she run? Did she and Peter run ops together?
Her normal life - What did she do with her sisters? How did she meet Peter? What kinds of dates did they go on?
Anything involving the two mixing together

Peter

His life in the resistance - How did he join the resistance? (Via Lise or some other means?) What kind of ops did he run? Did he and Lise run ops together?
His normal life - How did he meet Lise? What kinds of dates did they go on? Did he meet her sisters? Did they like him?
Anything involving the two mixing together

Ellen

After the war ends, does she come back to Amsterdam? Does she make contact with Annemarie?
What does she do after she flees to Sweden?
What was her life like before the Nazi occupation? How did she and Annemarie meet?

Annemarie

What was her life like before the Nazi occupation? How did she meet Ellen?
Does she join the resistance? Does she send Ellen letters?
Relationship with her sisters - How does her relationship with Kirsti change as they grow up? How does her perception of Lise change after Ellen's escape? What was Lise like before she died?

Singular Menace - Odin Remby, Shay Remby, Twist
A girl on a mission to find and save her brother (along with some friends/allies) uncovers the actions of an evil corporation along the way! I really liked the seriousness of this canon and found the "science" interesting.
This series is three longish books, and there are spoilers for the first two.

Shay

Pre-Uncaged Life - How often did she talk to Odin? What was her life like? How was she doing in school? (She probably skipped a year of math somewhere, but we don't know anything beyond that.) How did she meet graffiti artists in Eugene?
Relationship with her mom - What was it like before she died? Did she teach Shay anything? Is she really dead?

Odin

Animal activism - How did it start? How did he meet Rachel/Storm? How does it continue as he grows up?
Tech skills - Where did he learn them? How did he develop them?
Relationship with his mom - What was it like before she died? Did she teach him anything? (His tech skills? About animals?) Is she really dead?

Twist

Backstory - we get hints of it (former foster kid, at one point homeless, leg injury from being badly beaten while homeless, etc.), but I'm really curious how he ended up running the Twist hotel. How did he meet Dum and Dee? How did he meet Cruz and Cade?
Kids he's met over the years - weird situations, things that went incredibly wrong/right, etc.
His art - how did he get started? Was it always explicitly political?
(Mis)adventures - judging by the hotel stunt at the beginning of Uncaged (and his general willingness to roll and/or assist with Shay's stunts), Twist has done a lot of crazy things. What was his first stunt like? How did it turn out? What other crazy things has he done over the years? Why?

The Time Hunters - Percy Halifax, John Mellor, Becky Mellor, Joe Mellor
Time travel hijinks! I liked the variety of times and places they traveled to (and the costumes they wore there) as well as Bowen Hall's menagerie of animals from the past. The characters' relationships to each other were also wonderful and very compelling.
One quick reminder that this is the series by Carl Ashmore, not the one by Chris Blake. (The titles should follow the format "The Time Hunters and the _ of _" instead of being one word.) This series is five books long, but spoilers are mostly for the first book only, with some details from later books in the "John" and "Joe" sections.

Percy

The OTTERS - What were they like? What kind of (mis)adventures did they get up to? Did they build their first time machine together? (If so, what vehicle was it? Who kept it?) Were their any signs of Drake's villainy before he faked his own death? Do they ever meet up after they graduated (and some of them stopped travelling?)
Bowen Hall's creatures - How did Percy get some of them? Do they have any unusual habits? Which ones are his favorites? Maria's? Will's?
Percy is used to losing people. He's not used to them coming back into his life alive, especially after he's heard their dying words. (Can be played as either comedy or tragedy.)
His inventions - How well do they work? How well do they sell? How long do they take to make? Have any of them gone hilariously wrong?
Relationship with John - It's clear that these two love each other but don't always understand each other. How does John react when he learns that Percy kept the secret of time travel from him? How did their last fight go? (How much of it was really about the kids? Did Percy point out John's hypocrisy on the subject since he had interfered in both of their lives using time travel?) If John hadn't been captured, would they have eventually made up?
Meetings with other time travelers - How well do they get along? Do they ever cross paths in the past? (I really liked the bits with other travelers in the later books - the city, the GITT party, Bruce the florist/cowboy... all of it)

John

How much did he know about the relics before he was captured? How did he get the Suman Stone? (Did Edgar give it to him, knowing that it would end up in Becky's hands? Did it come up with the disk from Knossos? Did it fall into mortal hands at some point?) Why did he give it to Becky? (Did he think it best to hide it in plain sight, or did he not understand its significance?)
His time imprisoned - Did he know anything? Did he tell Drake anything? How did Drake try to coerce him into talking?
Relationship with Percy - It's clear that these two love each other but don't always understand each other. How does John react when he learns that Percy kept the secret of time travel from him? How did their last fight go? (How much of it was really about the kids? Did Percy point out John's hypocrisy on the subject since he had interfered in both of their lives using time travel?) If John hadn't been captured, would they have eventually made up?
Adventures in the ice cream truck - Where and when did he like to go? What sorts of trouble did he get into? Did he ever take Becky, Joe, and/or his wife with him? (Before or after he got back - either is fine by me.)

Becky

Her powers - Where do they come from? What are their limits? Do they diminish over time or get stronger/stay as unpredictable?
Animals - She bonds with most of the less-than-human cast. Which ones are her favorites? Why?
History classes get a lot more interesting for Becky and/or the other students.
Living a normal(ish) life after the last book ends - Visits to Uncle Percy, going to school, going on dates, and generally being a normal teenager with some caveats attached.

Joe

In an attempt to save Will, Joe ends up stuck in the past. He takes the opportunity to be ones of his childhood heroes: Robin Hood.
History classes get a lot more interesting for everyone involved. (Blurting out details about the Argonauts, claiming that Robin Hood's Merry Men were real, generally giving his teachers a headache, etc.)
Return to Normal(ish) life - How does he deal with having his dad back? Do they go out to visit Uncle Percy (and the past) sometimes?

Time Traveling hijinks - aka canon without Drake

How did Percy collect some of Bowen Hall's creatures?
Meeting your past self is strange. Nearly being killed by your past self is even stranger.
Accidental severe damage to the timeline - What happens next? How do they fix it?
Costumes for the past

Fullmetal Alchemist: Brotherhoold and Manga
Complex plot, badass female characters, tightly defined magic, badass female characters, horrifying government conspiracy, badass female characters, epic fight scenes, badass female characters... Throw in cool music and this show would cater perfectly to my tastes! I love everything about Brotherhood and the manga, but never managed to get into the 2003 anime, so I would like anything to be in the Brotherhood/manga universe.

Out of all the members of the Chang clan, why was May sent to Amestris? And why did she go alone?

Childhood with Alex
Does she have anything of her own that's been passed down through the Armstrong family for generations?

Harry Potter: Books
This was my first fandom when I was a kid, and I still haven't managed to escape the magic of it.

Books. Anything about books.

Angelina Johnson

Quidditch at Hogwarts
What did she do during the war? What did she do after it ended?
After she graduated, did she join a professional Quidditch team or did she keep her interest as a side hobby?

Harry Potter: Founders Era
What most intrigues me about the founders is that we know next to nothing about them. Where did the founders come from? How did they meet? How did they build the castle? We don't know! Any knowledge of the period would be great, but if it's inaccurate, I probably won't be able to tell.

Helga Hufflepuff

Backstory - where did she come from? What was her family like? How did she meet the other founders?
When Helga said she'd take them all, she meant it. (A werewolf/squib/etc. wants to attend Hogwarts, and Helga can't turn them away.)
Teaching in the early days of Hogwarts.

Rowena Ravenclaw

General backstory - her family, how she met the other founders, etc.
Establishing and running Hogwarts
Pottermore mentions that Hogwarts is called Hogwarts because Rowena dreamed of a pig leading her to the site. Did this really happen, or was it made up? If it's real, were prophetic dreams a normal thing for Rowena or was it a one-time thing?

Hunger Games: Books or Movies
I love Hunger Games mostly for the twistedness: child murder, adult fear, the fact that the victors don't get to live in peace afterwards... go as dark as you want, honestly.

Rue

Life before the reaping - What's her family like? Did she go to school? How was work?
Reaping day - There's some uncertainty in the books of how Eleven does its reapings due to its large population, so maybe something off of that. Emotional angst is a given.
Preparing for the games - interviews, the chariot ride, training, etc.
The Games - What did she do in the games before meeting Katniss? Why did she help Katniss? How did she get trapped?
Aftermath of her death, maybe?

How much did she know about the rebel's plan going into the Quarter Quell? How much does she understand?

Mags

Before the games - Mags was a child during the Dark Days, so maybe something stemming from that.
What were her games like? - arena, strategies, features that have fallen out of favor or aren't in practice yet
Her life as a victor - mentoring, watching the games change over the years

Annie Cresta

Her life before the games - because that seriously screwed her up.
After the games - Was she even worse in the beginning? How does she cope?
After the war - Does she get better? What's her life like?

Steven Universe: Show
This show manages to line up with my tastes really, really closely. The balance of (and occasional wild oscillation between) a fluffy kid's show and something really dark, the way it handles its characters (mostly Pearl's) issues, the music, the various gems and their assorted badassery and awesomeness... I wish we could get a new Crystal Gem for more than about an episode at a time because the ads are kind of bait-and-switch in that respect, but there's little else I could ask for.

Pearl

Her issues. Any (or all) of them.
Repurcussions from the Sardonyx incident
Does she hook up with Mystery Girl?

Garnet

Internal dialogue between Ruby and Sapphire
Does she still have the ice/fire powers in fused form
Futurevision - its benefits and drawbacks

Lapis Lazuli

The making of the meep-morps
Living at the farm with Peridot
It's taken some time, but she's grown to like Earth.
Her exploring the oceans - she has power over water, so she can find the cool stuff really quickly, and she doesn't need to breathe, so she doesn't have to worry about getting the bends or resurfacing for air.
Fighting as a Crystal Gem

Bismuth

AU where she's not bubbled at the end of her episode
Various creations of hers - are there non-weapon ones?
She finds Crazy Lace, Biggs, and/or Snowflake. It's not pretty. (I've seen some speculation that the two big corruptions at the Beta Kindergarten were Crazy Lace (Aget) and Biggs (Jasper), and I think it's a pretty clever idea.)

Connie

Clearly, she's had a talk with her parents since Nightmare Hospital. How did it go?
Fighting corrupted/homeworld gems, with or without the others
moments of geekiness

Famethyst

Reuniting with the Crystal Gems
Pranks they've dealt on Aget

Garnet & Pearl & Amethyst

(Trying to) raise Steven
Dealing with Rose being gone

Connie & Pearl

Connie's sword training

Steven Universe: Rose's Rebellion
Because we know next to nothing about this time, and it his the "morally dubious protagonists" spot hard. Fight scenes are a very good option for all of these.

Pearl

Backstory - who did she belong to? How did she escape them? How did she meet Rose?
Rose is mostly a strong, charistmatic figurehead; she's the real brains of the rebellion.
Starting her role in the rebellion as a spy - no one pays attention to people they view as lower, so no one would suspect them.
How did her issues surrounding Rose spring up?

Garnet

The first few awkward days (weeks... months... years...) of joining the Rebellion
Her splitting up and going undercover.
Using futurevision to plan attacks, and something going horribly wrong.

Lapis Lazuli

Why did Homeworld assume she was a traitor?
Why was she locked in the mirror?
Using Earth's water (oceans, rivers, ponds, clouds) as her primary weapon

Rose Quartz

Why did she start a revolution?
Meeting the others, one by one
Rose is the head of the rebellion, but she's not sure she can control it.
Shattering Pink DIamond - Why? How?

Bismuth

Backstory - where did she come from? Why did she join the Rebellion?
Why did she think the Breaking Point was necessary?
Her starting in the rebellion not as a soldier or weaponmaker but as a spy - no one paid attention to her, and she definitely has the ability to lie well enough to do it.

Group: Bismuth & Rose Quartz

How did they get along before the Breaking Point?
Their argument
Bismuth's Bubbling - why did Rose think it was necessary to do and hide it? Did Bismuth think it was a temporary thing at the time?

Original Work: I requested these in sets as well as under the "Original Work" canon helper, but I'm fine with getting any of these characters in any genre.

Original Work Only - Because these didn't scream a particular genre to me. Knowledge of the character's field is a plus.

Teacher

What are her students like?
How does she feel about them?
How does she feel about her coworkers?

Engineer

Her day-to day job
Something goes horribly wrong, and only she can fix it.

Scientist - Any field, any point in time (or not - speculative is okay, too!)

Things go horribly wrong (or right).
Things blow up in her face (literally).
Field-specific info
If (faux) historical - How did she get to her position? (I love stories of early female scientists working hard to get the respect they've earned.)

Doctor

Patient comes in with mysterious illness and Doctor must diagnose and save them!
General day to day job - what field does she work in? (e.g., pediatrics, radiology, oncology, cardiology, ENT, the list goes on and on... maybe even a vet?) What are her patients like?
If sci-fi, treating aliens with anatomical differences

Archaeologist

Her latest dig uncovers some interesting artifacts.
Paperwork associated with digs
Writing things up for a museum exhibit/acting as a docent, maybe?

Revolutionary - Any revolution, fictional or real (if real, preferably googleable so I have some clue what's going on)

What are they fighting for? Why?
Do they get what they're fighting for?
Cue Les Mis jokes (or Hamilton or 1776 jokes, if you would prefer) - men in tight pants, breaking into song, life about to start in heaven, etc.

Science Fiction

Natural Scientist on Newly Discovered World

What does the planet look like? - Composition, atmosphere, weather patterns, solar system
Can life live on it? (Is life already living there?)

What are her methods like? (deep cover, honeypot, hacking, anything at all - plausibility is not the issue here)
Her cover is blown, and she needs to escape in one piece.
She meets some allies along the way.

Superheroine

Saving the world isn't easy, especially when you're also going through school/holding a job/taking care of someone/etc.
Calamity as cock(or, rather, vagina)block - her dates keep getting interrupted (in increasingly ridiculous ways and at increasingly exasperating times) by supervillain attacks/alien invasions/monster attacks/etc.
Her identity is revealed, and she has to face the fallout.
Revolving door of impermanent deaths

Supervillainess

Why is she evil? (Megalomania? Boredom? Evil via method and not intent?)
Her cunning schemes (and how they blow up in her face)
If going the "Evil Because I Can" or "Evil Because I'm a Megalomaniac" routes, signs her parents really should have caught of her future evilness. (Personally, I'm picturing entirely impossible plans of DOOM in scribbled in crayon.)
What's her life like outside of world domination?
Revloving door of impermanent deaths

Politican

Debates, either polite and respectful or devolving very quickly into nastiness
She is targeted by Spy.
Politics is an art of compromise and talking (sometimes yelling) over other people. She's still working on that first part.
How did she get into politics?
Is she the Intrepid Idealist (who's about to have her dreams crushed) or the World-Weary Pragmatist (who will realize she's forsaken her principles for action)?
She manages to get something she wants done. She celebrates.

Has she always been a mad scientist, or did she start out normal(ish)?
She's a botanist, and things go wrong with some genetic manipulation. (aka She makes an Aubrey from Little Shop of Horrors)
She's a chemist and almost blows up the city.
She's a doctor, and human experimentation is involved.
She's an engineer, and there are killer robots (or robot ninjas, or killer mechs, or any other ridiculous robot trope) involved.
She comes to her senses once everything has gone past the point of no return.

Mad Scientist & Monstrous Creation

Treating the monster like a precious pet.
The monster acts like a pet animal - turns over for belly rubs, hogs the heater, plays fetch, etc.
Full horror - The monster was formed from a loved one. (Note FMA request above)
The monster is the one in real control

ME is missing. Detective must find them.

Hello worldbuilder! I go by Brachylagus_fandom on AO3 and might take a bit to comment due to real life perpetually kicking my ass! Most of this letter boils down to "what would happen if x... SHINY THING!", but I will love anything not involving my DNWs. Feel free to mix and match prompts as well.

Mysterious Benedict Society - This series (by Trenton Lee Stewart) leaves a lot of interesting open ends for worldbuilding.

Backstory - In some ways, I think the backstories of the characters in canon could be more interesting than canon.

Milligan, before he got sent to Nomansan Island, afterwards, or a mix of the two
Other exceptional children Mr. Benedict found over the years (i.e., Rhonda, Number Two, or Exceptional Child(ren))
Kate at the circus
The Executives/Messengers, since it's implied some of them were kidnapped and brainswept
The Helpers, particularly why they were brainswept
As a non-character alternative, the progress of the Emergency

Media and Propaganda - What it says on the tin

Whisperer messages and the interpretations thereof
News during the Emergency
In The Prisoner's Dilemma, some of the media still favors Curtain despite lack of Whisperer influence and his various crimes being exposed. Why?

The Power of the Human Brain - Also exactly as advertised

An exploration of Constance's vaguely defined mental powers
The Whisperer/Brainsweeper
Sticky's memory and occasional failings thereof

Technology - This is an excuse to let your STEM flag fly.

The Ten Men's equipment
The Whisperer/Brainsweeper and how they work
Mr. Curtain's various other gadgets and how they came into being
On a much less advanced note, The Annotated History of Kate Weatherall's Bucket would not go unappreciated

Paperwork - I pity whoever has to file the paperwork involved in this series.

The strange questions that have to be asked.
The stranger answers. Mr. Benedict is shown to deliberately irritate the officials by giving weird replies, Sticky's report would put anyone to sleep, Constance is Constance, and Kate might write in invisible ink just for kicks.
There's always a form for that.
Artistically, maybe a pile of paperwork?

Ten Men/Recruiters; Messengers and Executives - The collective evil henchmen of the series. (For potential clarification - the Ten Men are more or less the same thing as the Recruiters but after LIVE disappears).

Where they came from originally
A look into a Ten Man's briefcase
Sashes are earned in tears; watches are earned in blood.
Jackson and Jillson being the unlovable assholes they are in canon
Someone tries to teach SQ to be a bad guy.
Martina Crow's dignified career being an asshole.

The Weatherall family - MY BABIES.

Kate's mother is not as dead as advertised.
Milligan's life pre-Nomansan Island
Their life in between chaotic adventures
Kate at the circus
Issues in adapting to having someone to rely on/care for
Basically anyting with Kate, Milligan, and possibly Kate's unnamed mom.

Harry Potter - Wizarding World - This chunk focuses mainly on logistics of stuff, which sounds boring but is ~~probably~~ ~~still boring to you~~ going to be totally awesome!

Libraries

Is there a magical version of the Dewey Decimal System?
Books that bite or have other strange qualities
Charms against books becomeing overdue
How do holds/interlibrary loans work?
Are there magical library cards?

Knitting

Do you have to pay attention to magic knitting in order that it follows your pattern (instead of doing a basic stitch) or can you "program" it in?
If you can "program" the spell to follow a set pattern, how do you do it?
Is there a spell to fix mistakes twelve rows up? (If so, can I have it?)

The Scientific Method

Some very bored muggleborn gets the bright idea to experiment with their powers.
Magical person decides to test the "laws" of magic.
The making of the Maurader's map included a lot of trial and error.
The making of Snape's special potion recipes

Higher Mathematics - including applied mathematics

How did the invention of the calculator (in particular the log, root, and trig functions) affect Arithmancy?
Did astronomical math modeling help or hurt astrology?
Can quantum mechanics explain the effects of Potions?
Mathematical proofs explaining (or failing to explain) how magic works.
Applied math + math = impressive chaos

Songs

Can music be used as a spell?
How do the words affect the end result?
What effects to the compositional elements have on the end result?
Music theory/history injokes if you have them

Wizarding Interpretations of Fairy Tales/Wizarding Version of King Arthur Myths

How do these differ from the nomagical versions?
Is Avalon a real place?
Creature representation (i.e., Big Bad Wolf as a werewolf or Nimune as some kind of water-based creature)?
Is magic applied differently?

Dragon Sanctuaries

Where does their funding come from? (Government? ASPCA-type ad campaigns? Donations? Wealthy nature enthusiasts?)
What regulations govern dragon sanctuaries?
Do they act as preserved versions of biomes (like a national park) or more like a large, well-kept, dangerous zoo?
What is day to day life there like?

Harry Potter - Books Only - Again, it is clear that I am a huge worldbuilding dork. I do not particularly care whether or not some of these are set in Britain or anywhere else (and actively encourage other locations for History of Magic and Magical Societies).

Politics - These could apply to either magical Britain or magical somewhere else.

How does the ministry work?
What is their relationship with their muggle counterpart like?
How do the politics of the muggle world map onto the politics of the magical world?

Ministry of Magic

How do the different departments interact?
What is a day in a ministry job like?
Strange paperwork and the reasons it's necessary

Politics of the resistance against Voldemort

Are there groups other than the Order of the Phoenix fighting Voldemort?
What does the logistics situation of either war look like?
Who do magical creatures ally themselves with? Why?
What protections were put into place afterwards to avoid this sort of this happening again?

History of magic and magical societies - This mostly focuses on older history, but a more modern timeframe would not go amiss.

How far back do magical societies go?
Was magic useful in the building of early states?
Magic's influence on the construction of monuments (e.g. pyramids, Stonehenge, Great Zimbabwe, Great Wall of China, Ansazi lines, etc.)
The introduction of magical seclusion
How does magic relate to belief systems and social hierarchies?
How closely do magical conflicts mirror muggle ones?
To what extent does anti-creature sentiment parallel racism in the muggle world?
Does anti-magic sentiment rise along with other scapegoating in the muggle world?
Is there any actual basis for anti-magic sentiment?

Literature (fiction and non-fiction)

What genres of fiction are popular?
Non-textbook, non fiction works, particularly in history
Is there a version of AP prep books for OWLs/NEWTs? Does Hermione have a full set?
The rise of printed works. Did they need to wait for the development of the printing press (in Mainz or in China)?
The wizarding version of fictional genres (adventure, kidlit, romance)
Is there a set of books based on the life of Harry Potter? Are they accurate or hilariously embellished? Where they written before or after the events of the story?

Magical features of Hogwarts castle - Exactly what it says on the tin

How many of the features originated as defense mechanisms?
Can a full map of Hogwarts even be made?
How was the Marauder's map designed?
How were the magical features created?

Why was it founded?
How was it maintained?
A look into its collection

How does being split into three alter the waterbenders' political power?
What effect does bending have on one's political power?
What are the internal power structures of each kingdom (maybe plus the United Republic) like? How have they changed over the years?

Applications of Bending - Specifically, things other than violence.

Waterbending - hydroponics, magic painting/calligraphy
Firebending - fire is used in a lot of stuff - lighting, heating, forging metals
Earthbending - easy construction of cities, early warning of seismic natural disasters, finding mineral resources
Airbending - flight, detection of weather systems
Combinations of elements
Boring, mundane stuff - drying hair, making tea, heating ovens

The History of the A:tLA World

Formation of Four Nations
Development of trade networks
Epidemics?
Rise of massive states along bending lines

Creation of the United Republic of Nations

How did the United Republic get the necessary land?
How did Sokka promote the idea?
Planning and constructing Republic City

Steven Universe - Lots of open ends to poke through

Why is there an ocean where Siberia is meant to be?
Human exploration of gem sites
Was there genetic bottleneck because enough people died in the Gem conquest of Earth?
Did gem artifacts speed up technological advancement?
Impact of Rose's Rebellion on early religious systems

Rose's Rebellion

Where did the Crystal Gems come from?
Tactics in the war
What role did humans play in the fighting?

Gem Politics

Were there other factions fighting in Rose's Rebellion?
What does Homeworld's hierarchy look like?

How are Kindergarten locations picked?
Effects on the environment - Can they be avoided? Are they reversible?
What happens when Kindergartens go wrong?

Gem Corruption

Is corruption a side effect of physical issues (i.e. a cracked gem), mental ones, or some combination thereof?
Is it communicable?
Can it be reversed?
How was it first discovered?

Educational Materials

How different is education depending on district?
Does the curriculum change depending on job? (e.g. a coal miner wouldn't have a use for vectors or calculus but a structural engineer would)
What is each district's curriculum like?
Do they have to take standardized tests?

Hello! I go by Brachylagus-fandom on AO3, and I'm already excited about what you're writing even if you have no clue what you're writing. It's going to take me a couple of hours to a couple of days to comment for fics in this exchange due to real-life difficulties. Prompts below are sorted by fandom and relationship, but feel free to mix and match from other relationships/fandoms if inspiration strikes you.

a plausible but dark interpretation of canon
characters/settings turning out to be much darker than they appear
awkward relationships and misunderstandings
women kicking ass/being competent
hijinks. Literally, if you make something that can be summarizes as "hijinks ensue," I will lap it up with a spoon.

Fullmetal Alchemist: Brotherhood & Manga: This show is a combination of a lot of my favorite elements: interesting worldbuilding, badass powers, and the characters being somewhat scarily competent and not afraid to show it.

Alex Louis Armstrong & Olivier Mira Armstrong

Olivier protecting Alex when they were younger
Why their relationship is so awkward
One time Alex had to be the tough one
When it comes to stereotypes not based on looks, Alex is definitely the more feminine one, and Olivier the more masculine. When they were children, a lot of crossdressing occurred.

Olivier Armstrong & Buccaneer & Miles

Hijinks at Ft. Briggs
fix-it for the incident at the end of canon

Olivier Mira Armstrong & Izumi Curtis

Izumi is being a menace around Briggs, and it's Private Armstrong's job to stop her.
Although they're similar in attitude and fighting capability, they're on opposite sides of pretty much everything else. How does that affect their relationship
Hijinks in Dublith, Briggs, or anywhere else in canon

Alphonse Elric & Edward Elric & Winry Rockbell

Ed and Al have always been too good at getting hurt. It's Winry's job to fix them up again.
Before their parents died, they were normal kids in Resembool. What did they do?
Winry and Ed swapped textbooks one day because Ed needed to know stuff about human anatomy for the human transmutation. By the time main canon rolls around, there are three alchemists from Resembool on the loose, and one of them knows exactly how to rearrange your guts so that your death is slow and painful.
Potentially in tandem with the prompt above, Ed and Al dragged Winry along to help with the transmutation. (Maybe they thought that they needed more help with the medical end or more power overall.) This could lead to Pinako finding out before the incident happened and stopping it/calling Izumi to yell at them/yelling at them herself, or there could be three alchemists from Resembool who didn't need transmutation circles.

Alphonse Elric & Edward Elric

Ed and Al go on a mission. Things go wrong. Hijinks ensue.
Ed is very, very protective of the massive suit of armor that follows him around.
Small, fluffy animals find their way into the armor as a matter of course. Ed reacts the way he does in canon.

Izumi Curtis & Alphonse Elric & Edward Elric

Izumi really, really needs to stop finding lost children, especially ones with as little common sense as Ed and Al.
Ed and Al weren't the first nor the last children Izumi took in. Ed and Al deal with the others as best they can, otherwise known (for Ed) as poorly.
Izumi figures out their plan before they attempt human transmutation, and Ed and Al lose their hearing instead of an arm, a leg, and a body.
A day in the life of training with Izumi.

Garfiel & Winry Rockbell

A day in Rush Valley.
Automail was not the only thing Garfiel taught Winry.
Garfiel somehow knew Winry's parents and talks to her about them.

Winry Rockbell & Scar (Fullmetal Alchemist)

A very awkward conversation as they head south
People (patients, colleagues, whatever) bring flowers to the Rockbells' graves all the time, so the only thing that surprises her about this one is the scar across his face.
Scar has an arm that can destroy anything it touches. Winry has some medical knowledge and a wrench. Their quest for revenge is not very well thought out but effective nonetheless.

Paninya/Winry Rockbell

The coolheaded thief, the easily angered mechanic, and the love story that made Garfiel weep
Paninya's leg guns jam, and Winry gets to do the saving.
For some reason, the Amestrian military tries to take Rush Valley. They do not get very far.
Some very awkward dates

Pinako Rockbell & Winry Rockbell

Of all the things Pinako expected to attend, her granddaughter's funeral was not one of them.
Winry is young, and Pinako is raising her alone.
It's (Grand)mother's day!
Pinako teaches Winry about automail

Mei Chan | May Chang & Ling Yao

They are supposed to be enemies. The closest they get to that is aggravated allies.
May has been alone for a long time, and Ling is in need of some company.
Ling's heir presumptive is the girl who had his back and almost brought home a homunculus.

Mei Chan | May Chang & Scar

They're both lonely, albeit for different reasons.
Revenge quests go a bit differently when there's a pint-sized assassin by your side.
hijinks on the way to/from Briggs
After the time he's spent with May, Scar has decided to never have kids. Ever. His hair is white enough already, thank you very much.

Greed (Ling) & Ling Yao

Greed liked the foreign prince because they were similar.
Having a second voice inside your head is incredibly weird. Getting used to and then losing it is even weirder.

Maes Hughes & Roy Mustang

In Ishval, they were barely keeping each other sane. Now, Maes is the one driving Roy up the wall.
Maes teaches his daughter to call his colleagues "Aunt" and "Uncle", and "Uncle Roy" is her favorite.
Hijinks that do not quite go according to plan.

Harry Potter: I love the Harry Potter universe's fundamental weirdness and the way the characters grow up over the series.

Crookshanks & Minerva McGonagall

Two cats take a stroll though the grounds.
Crookshanks has found the second best napping spot in all of Hogwarts: McGonagall's classroom/office/room.

Hermione Granger & Minerva McGonagall

A time turner is a serious responsibility, but Minerva knows Hermione can handle it.
McGonagall tells eleven-year-old Hermione about magic.

Minerva McGonagall & Pomona Sprout

There is a reason the greenhouses don't contain catnip.
When the war ends, they are left to rebuild Hogwarts.

Minerva McGonagall & Poppy Pomfrey

McGonagall would really like to stop spending quite so much time in the infirmary because her lions keep getting hurt.
McGonagall gets magical flu/chickenpox/shingles/etc. Madam Pomfrey learns just when the Gryffindors get their stubbornness from.
Minerva fights. Poppy heals. They survive a war.

Minerva McGonagall & Rubeus Hagrid

Hagrid decides that the use of animals in Transfiguration classes is inhumane and protests against it.
McGonagall taught him once, and she still thinks he wouldn't have opened the Chamber of Secrets. Unless there was some suitably "misunderstood" creature inside.
The Basilisk incident was not the only time Hagrid was caught with an inappropriate pet.

Neville Longbottom & Luna Lovegood & Ginny Weasley

They survive a year of enemy occupation and rebellion together.
Keeping secrets was a skill they had learned in the DA and honed to perfection while hiding from Death Eaters.
Hijinks

Luna Lovegood & Charlie Weasley, Luna Lovegood & Newt Scamander, and Charlie Weasley & Newt Scamander

bonding over cool creatures and limited (human) friends
There is a second (dismissed) volume of Fantastic Beasts, and all of Luna's creatures are in it.
Newt has always like Thestrals, and the girl who visits them isn't half bad.
Someone keeps stealing/depositing dragons on the preserve. Charlie has to figure out who is doing it and why.
The odd girl who live just over the hill is the only one who shares Charlie's fascination with creatures.
Creature hijinks

Bellatrix Black Lestrange & Narcissa Black Malfoy & Andromeda Black Tonks

Andromeda knows her sisters are trying to kill her, but they're still her sisters.
Andromeda leaves. Bellatrix and Narcissa (try to) follow.
Their (doubtlessly fucked-up) childhood

Percy Weasley/Oliver Wood

Percy only pays attention to Quidditch when Puddlemere United is playing.
Dorm room fights and make-ups
"Why on Earth did we get married?"/"We were blinding drunk from the victory party."

Hermione Granger & Remus Lupin

Hermione figures out Lupin is a werewolf over the course of third year and how that alters their relationship.
Hermione is Lupin's favorite member of the Golden Trio because he sees himself in her the same way he sees James in Harry and Sirius in Ron.

Avatar: the Last Airbender: I appreciate this show's balance of fluff, humor, and pretty dark moments and its handling of allegiances and motivations.

Zuko & Ursa, Azula & Ursa

The world's most fucked up sibling rivalry
Azula is a bit of a sociopath, and Ursa doesn't want to accept it.
Very awkward/dangerous family vacations
Some time when the Fire Nation's Royal Family was not a hot mess.

Mai/Zuko

After the war, they have a long talk about not being quite so emotionally stunted.
Raising the Crown Princess is a challenge when neither you nor your husband knows how to actually raise a child.
Zuko says goodbye to Mai in person before the eclipse. I could see this going one of three ways: down in flames, an awkward but heartfelt goodbye, or Mai going with him on his quest.
"I love/hate you."/"I know"

Mai & Ty Lee

Azula is insane, and they have nowhere to run.
Ty Lee keeps one of Mai's knives with her for good luck.
A conversation set after the Boiling Rock

Azula/Ty Lee - Their relationship is so gloriously fucked up in canon. Anything (up to and including heavily dubious if not nonexistent consent) goes with these two, especially power games and manipulation. Ty Lee struggling to come to terms with what Azula's done/is doing would be amazing as well.

Fantastic Beasts: Hello, cute creatures and more Potterverse! This was a really interesting movie and I'm excited to see where the next one takes us.

Frank The Thunderbird & Newt Scamander, Newt Scamander & Newt Scamander's Magical Beasts, Newt Scamander & Newt Scamander's Niffler, Newt Scamander & Pickett, Jacob Kowalski & Newt Scamander's Niffler - Mostly just looking for adorableness here, though hijinks would not go unappreciated. Especially with the Niffler getting into everything known to man.

Credence Barebone & Modesty Barebone

They don't talk about Mary Lou. They really need to talk about Mary Lou.
There's more than one obscurial running around New York during the movie.
After the movie, (magically alive) Credence takes Modesty and runs.

Queenie Goldstein & Tina Goldstein & Jacob Kowalski & Newt Scamander

hijinks in New York
Jacob gets back his memory and goes out in search of his friends.
When Newt returns to New York, he brings with him three copies of his book as well as three appendices: one about the animals' diets, one about the threats they pose, and one about their minds/illustrated guide.

Queenie Goldstein & Tina Goldstein

Queenie knows her sister's mind better than anyone else's.
Queenie getting roped into one of her sister's cases because of Legilimency.
Tina practically raised Queenie, and is very protective of her sister.

Original Work: Unless implied otherwise, this is an equal-opportunity glurge of tropes. This section is divided into a couple of subsections by genre, but feel free to take relationships in a different direction as you see fit; it was mostly me trying to organize my requests in a way that lumped similar ones together.

Royalty

Emperor In Civilian Disguise/Oblivious Male Revolutionary - pretty much what's on the tin. Bonus if the Revolutionary's obliviousness extends to telling Emperor his plans to assassinate the emperor, the emperor is a failboat at civilian disguises, all of Revolutionary's compatriots figure out Emperor is the emperor relatively quickly, Emperor takes Revolutionary's ideas into account, or this is not a one-time situation.

Handmaiden/Princess

Handmaiden knew that the royal advisor would tell her to bed the Princess eventually. She did not expect to enjoy it.
Formal clothing, especially for princesses, is a pain in the ass to get on and off. Handmaiden helps.
People looking for the princess' consort never check the spot a step behind and to the left.
"What happens when your father dies?"/"I become queen, you become the Queen's Lady, and we kill everyone in our path."

Princess/Wizard

Many black magic rituals demand the sacrifice's virginity, so ensuring that the Princess lacks that quality is Wizard's most responsible course of action.
Princess and Wizard are a triple threat: adorable, powerful, and deadly both apart and together.

Queen & Female Knight

No one ever expects the "handmaiden" to pull a sword out of her petticoat.
"I swore to protect you."/"And I swore to protect the people of my realm, including you."
all the loyalty kink

Reserved Queen Mother & Estranged Princess Daughter

"One day, you will be queen and have daughters of your own, and I hope that they are just like you."
They can't afford to be emotional deal with their problems; there's a war on.
Estranged Princess Daughter does increasingly impressive and/or dangerous things in an attempt to get Reserved Queen Mother's attention.

Action

Superheroine/Superheroine

They can't get through a date without some crisis happening. (One of them strikes a deal with the local villain to run interference at certain times so she can actually get some.)
Their first kiss/confession of feelings happens during/directly after a fight and is caught on a TV camera.
Superheroine 1's secret identity has been discovered, but the villain doesn't realize that her girlfriend (Superheroine 2) is also superpowered. A subversion of the damsel in distress trope ensues, potentially with angry ranting from 2 and 1 laughing at the villain's pain.

Lesbian Superhero & Lesbian Supervillain

I really like the idea someone had during ToT of Lesbian Superhero and Lesbian Supervillain knowing each other through mundane means.
They're drinking buddies and gripe to each other about all the small (and large) problems. Incidentally, that's one reason Superhero is good and foiling Supervillain's plans.
They're awkward semi-ex friends in all that entails.
Their constant battle is over who gets to date Cute Lesbian Bystander.
They're roommates/dormmates and take far too long to realize that they're mortal enemies. The suspension of ignorance can go as hilariously far as the author likes (bandaging each other's wounds, hiding costumes in the back of the same closet, Supervillain bringing superweapon plans home, etc.).

Lesbian Superhero/Lesbian Supervillain

Asking your ex for relationship advice is far more awkward when your ex has a superweapon and is trying to kill you.
They don't realize the other's secret identity until after they start dating.
On the darker side, Lesbian Supervillain is really into Lesbian Superhero, but Lesbian Superhero is in a happy relationship elsewhere. Creepy stalking ensues.
"Honey, if you want to call yourself a superhero, you need to do better than that?"/"Sweetheart, if you want to be a proper evil overlady, you should maybe not leave your plans out for me to tinker with. Or actually take a course in [relevant field of study]."
The head of another villain as a Valentine's Day gift.

Madam President/Superheroine

interesting rewards for saving the world
They both fight evil but in different ways.
When Madam President was still Eager Law Student/Idealistic Lawyer, she may or may not have helped Superheroine get out of trouble with the law for vigilantism.

Female Secret Agent & Male Secret Agent

The Mission Drinking Game ("once the mission is over and you're medically cleared to imbibe alcohol, take one shot for…")
"You know, you should technically be the damsel in situations like this."/"I'll be the damsel when the bad guys stop thinking you're the softer target."
spy hijinks!

Spy/Rival Spy

They really need to stop meeting like this.
Spy gets sent on a honeypot mission with their mark being Rival Spy
"Can you just give me [MacGuffin]? Pretty please?"/"No."
When things go downhill ad they need to get out of the situation fast, they end up pretending to be a newlywed couple.

Time Travel

Time Traveler/Immortal

A love story that's out of order
"We have all the time in the world"
Immortal is getting sick of Time Traveler coming in and ruining their plans.
hijinks

Time Traveler/Other Time Traveler

romantic dates in other eras
Romantic dates gone horribly wrong due to poor planning or bad luck ("We're on a date. In Pompeii. Four hours before Vesuvius erupts. And our time machine's missing."/"Pretty much.")
Time Traveler A is dying, and Time Traveler B tries to circumvent this by traveling to the future for a cure.

Magic Practitioner/Non-Magic Practitioner

How do their powers/lack thereof affect their relationship?
Occasions where Non-Magic Practitioner is far more useful than their SO
Non-Magic Practitioner is a bit obsessed with trying to figure out magic, and Magic Practitioner thinks it's cute when they're asked how spells defy physics/where the extra matter goes/if truth serum is a barbiturate/where the eldritch horror in the basement came from/etc.
(Potentially in conjunction with the prompt above) Magic Practitioner is not familiar with modern society and causes chaos. Non-Magic Practitioner tries to minimize the damage.
"Why is there a smoking cauldron/runic circle/dragon/glowing artifact/eldritch horror/etc. in the basement?"

Steven Universe: I like the way this show goes from a happy kid's show about fighting monsters to really dark really fast and how the characters are far from perfect. There's also the music. I'm a sucker for music.

Pearl/Rose Quartz

Pearl has issues, and Rose doesn't know how to deal with it.
Rose hates watching Pearl sacrifice herself.
Loving Rose is an exercise in letting go, especially when someone else wins.
Rose Quartz may have lead the rebellion, but Pearl masterminded it behind closed doors.

Ruby/Sapphire

They do not function at all apart.
Being Garnet is an exercise of opening up and deliberately ignoring all of Homeworld's teachings.
They both have a lot of teachings to unlearn and baggage to deal with.
The first time Sapphire and Ruby unfused after Garnet became a Crystal Gem was a nightmare. They're not letting it happen again.

Bismuth & Lapis Lazuli

Bismuth is the reason Lapis got trapped in the mirror. Lapis can forgive, but she can't quite forget.
They've both done things they aren't proud of and bond over that.
Lapis goes to face Jasper and finds a bubble and Bismuth playing with two corrupted gems.

Pearl & Steven Universe

Pearl sees Rose in Steven's eyes.
Steven knows he and Pearl need to talk about Rose; he just doesn't know how.

Garnet & Steven Universe

Rose doesn't need to tell Garnet what she's planned; Garnet already knows.
Garnet can see Steven's future, and it's eventually a happy one.
Garnet and baby Steven

Rose Quartz & Steven Universe

Steven wonders if Rose is proud. She answers.
Rose knows that she's going away for a while, but they're at peace and the things her baby will do will make it worth it.

Amethyst & Garnet & Pearl & Steven Universe

Everything's going to hell in a handbasket, but they have each other, and that's enough.
Everyone loved Rose. Everyone was affected by Rose and her disappearance. Everyone is still having issues surrounding Rose.
Crystal Gem missions/adventures
Steven doesn't have one mom - he has three! Well, he has two moms and a cool but irresponsible aunt, which is kind of the same thing.

Connie Maheswaran & Pearl

Swordfighting is about balance, strength, and determination.
Getting her happy ending by proxy may or may not have been one of Pearl's motivations for training Connie.

Connie Maheswaran & Steven Universe

hijinks and adventures
Since both can play musical instruments and sing, they have a duet
Steven helps people and tries to save the unsaveable; Connie keeps him from dying in the process.

Connie Maheswaran/Steven Universe

When people compare Steven to Rose and Connie to Pearl, they're not exactly making large leaps of thought.
He's the protector, she's the attacker, and Stevonnie is a feared combatant.
"Let me do this for you."/"We do this together, Connie, or not at all."

Current Mood: excited

Hello, writer/artist! Two somewhat important things you should know: I go by Brachylagus_fandom over on AO3 and there is a high chance that reveals will occur when I am occupied by RL, so it might take several hours to a day for me to comment. I have a pretty wide range of likes, so just about anything not involving my DNWs would be fine.

For this exchange, I've divided prompts into tricks, treats, and either, with the last category being prompts that could go in either direction. If you feel you can make a good trick out of a treat prompt or vice versa, go ahead, and feel free to mix and match prompts as you wish.

Steven Universe (Lapis, Pearl, Amethyst, Bismuth, Steven, Connie, Garnet, Peridot)

I like this show a little too much. The way it goes from happy kid's monster-fighting show to angst of the highest proportions with some really serious subject matter is one of my favorite elements, both in SU and in general. I think that it handles a lot of pretty dark issues and its characters and their issues (including some of the villains) very well, especially for media aimed at children. Also, I'm a sucker for good music.

Tricks:

Nearly every character on this show has issues, and some (cougcoughPearlcoughough) have subscriptions. An exploration of these without a happy ending.
Conflicts of interest in any era
People they left behind
The Crystal Gems in the war era, especially since it's implied that there were a lot more of them
Steven learning the hard way that he can't save everyone.

Treats:

Moments of peace during Rose's rebellion or the current escalating tensions
Bonding
Some good old-fashioned hurt/comfort over everything that these characters have been through
A canon divergence where Bismuth either comes to her senses about becoming what she hates or the Breaking Point doesn't exist

Either:

Origin stories
Steven and Connie learning to fight/rescuing each other
Exploration of motives (e.g., why Bismuth thought the Breaking Point was necessary)

Harry Potter (Hermione, Neville, Luna, Weasley Twins, Lee Jordan, Founders)

I grew up on Harry Potter, and a decent amount of my brain has been dedicated to magic and mayhem for a very long time. I love the actual magic as well as the characters, especially Neville's arc.

Tricks:

Something set at Hogwarts during Deathly Hallows
Fighting the Death Eaters
Villains winning, at least for the moment
Coping with death, loss, and/or being left behind

Treats:

Hogwarts moments from before the Second War (e.g., Luna meeting some lonely person besides Harry, Neville and Herbology, the Twins and Lee)
moments of normalcy in wartime
hijinks and shenanigans, especially against Umbridge

Either:

Founders-era, with optional historical accuracy
Worldbuilding centered around interaction with the muggle world or magical history
The Twins running their joke shop
Something exploring Order of the Phoenix: Umbridge's thought process, defiance of the Decrees, a hypothetical situation where Harry was expelled from the magical world and how fifth year turns out then
Post-canon era - where are the characters now? Epilogue optional.
Exploration of character motivation, especially painting characters in shades of grey

Avatar: The Last Airbender (Suki, Ty Lee, Mai, Zuko, Iroh, Toph)

Again, I like this show's balance between humor, fluff, and dark introspection as well as its characters. I love how it handles changes of allegiance as well as motivations, especially how everything is painted in shades of gray rather than black and white.

Tricks:

Ty Lee and Mai gradually realizing that Azula is completely nuts
Azula's life in general
Life under the Fire Nation
Hakoda's or Suki's time as a prisoner of war
Something showing the main cast as the children they are/recently were
Dealing with loss, regularly ineffectively

Treats:

Iroh and tea, either dispensing wisdom over it or running his shop
Silly side stories like three-fourths of Tales of Ba Sing Se
Sokka being his sarcastic, idiotic self

Either:

Iroh's role as a surrogate father to Zuko and, as an extension of that one scene, Toph
Ty Lee's relationship with the other Kyoshi Warriors
Mai and Zuko's relationship
Backstory
Post-canon

Fullmetal Alchemist: Brotherhood/Manga (Izumi, Ed, Al, Hawkeye, Olivier, Hughes, Roy, Scar)

This show hits just the right spot for competency, badass powers, and interesting worldbuilding.

Tricks:

Ishval and its aftereffects, from the perspective of those fighting (Hawkeye, Roy and Hughes on one side, Scar on the other), adults at the time (Olivier, who I'm 90% sure was stationed elsewhere, and Izumi, who isn't in the military), or children at the time (Ed and Al, especially with growing horror as they realize just what happened there)
An expansion on the canonical human experimentation in the show (a la Tucker).
I always thought that the time when Roy's team was split up was a perfect setup for abuse, especially of Riza. Roy panicking as he realizes every action he makes could end with his team dead would also be perfectly acceptable.

Treats:

Roy and Riza falling in love with the worst timing possible
Izumi teaching Ed and Al as kids
The characters as children in general
Casefic with Roy and his team
Scar rebuilding Ishval

Either:

Unknown backstories
Life at Briggs
Hughes watching canon as a ghost

Original Work (Gay Superhero, Gay Superfoe, Lesbian Superhero, Lesbian Superfoe, Assassin, Secret Agent, Librarian, Scientist, Female Secretary)

This is a glurge of action tropes. Unless specifically mentioned either way, the characters can be of any gender. Gay Superhero is merged with Lesbian Superhero into Superhero; the same thing happens with Superfoe. Also, Female Secretary regularly inhabits roles more typical of a research assistant, intern, or manager.

Tricks:

Superfoe is crushing on Superhero, who is in a perfectly happy relationship with an innocent (gay/lesbian) bystander, leading to angsty dub/noncon over unrequited feelings.
Scientist is kidnapped to work for Superfoe.
Superhero is secretly Assassin.
Everything is set up, and Superhero and Superfoe are trying to escape.
Superfoe was right all along.

Treats:

Librarian's job is very interesting (i.e., Secret Agent in the stacks, Dewey decimal classification of books concerning death rays, Superhero obsessively reading all books on superpowers and sexuality).
Librarian is Secret Agent in deep cover.
Superhero and Superfoe fall in love out of costume. (commence identity porn)
Female Secretary has to deal with people being idiots, whether it is Superfoe ignoring the Evil Overlord List (and, if Lesbian Superfoe, maybe hitting on her), Scientist being Scientist, Superhero being not the brightest bulb on the Christmas tree, or Secret Agent having poor risk assessment skills.
Superfoe tries to be good, with poor results.
Awkward interactions due to being related/having known each other before they became action tropes.

Either:

Superhero and Superfoe's relationship, especially with awkward protectiveness (Superfoe being unwilling to let Assassin kill Superhero), identity crises, and enemy mine situations
Secret Agent is sent to gather evidence from/spy on Female Bodyguard's boss and runs into her.
Scientist has a general lack of risk assessment and common sense, especially leading to them becoming Superhero/Superfoe or creating a monster (Plant Monster, Mutant Penguin, and Tentacle Monster are examples from the tagset).
Female Secretary is Assassin or Secret Agent.
Secret Agent missions in general

DNW:

Smut
Excessive violence

Likes:

Fluff
Darkfic

Characters depending on each other
Misunderstandings
Honestly, just about anything will make me happy.

Avatar: the Last Airbender:

Iroh and Zuko -

What was their relationship like before Lu Ten died? Before Zuko was banished? While they were searching for the Avatar? After the war?
Iroh is the only adult that Zuko can rely on. I'd love to see how this comes into play.
Iroh's wisdom helps Zuko while they are separated.

Ty Lee and Kyoshi Warriors -

How does Ty Lee fit in with the others?
Cultural misunderstandings between Ty Lee and the others
The group getting along better than expected, especially in crisis

Toph Beifong and Katara -

Katara kind of acts like team mom, especially where Toph is concerned. How does this affect their relationship?
Toph saves Katara or vice versa.
Toph going to Katara for parenting advice.

Azula and Zuko -

Azula and Zuko being close and/or normal(ish) before his banishment.
Azula and Zuko reconnecting after the war.

May Chang and Scar -

A vaguely normal situation where May can and does act like a kid

Izumi Curtis and Edward and Alphonse Elric -

Moments with little!Elrics before they performs the transmutation.
Izumi coming around to yell sense into them after said transmutation goes awry.
I kinda picture Izumi as acting somewhat like a mother or aunt to them, so them asking her for advice.

General Info on Requested Canons

Avatar: the Last Airbender

I love how this canon bounces between a fairly average kids fantasy show and something a lot darker. The character arcs are amazing and the little oddities are kind of funny.

Discworld

I love the ever-present weirdness in Discworld, especially Death. I haven't read all the books but have at least a basic understanding of all the miniseries; my favorites are the Watch books, Going Postal/Making Money, and Monstrous Regiment.

Fullmetal Alchemist

I'm only really familiar with Brotherhood, so I'd like any gifts to be with that continuity. I really like how this series deals with some serious issues, its wonderful female characters, and Ed's ability to get out of trouble but inability to avoid it in the first place.

Harry Potter

The story in HP is good, but the worldbuilding is more interesting to me. That being said, I love Hermione and Luna, especially when they play off of each other; obscure branches of magic, magical-muggle interaction, and how the wizarding world functions are some of my favorite worldbuilding concepts.

The Librarians

I really think that this is a good canon for crossovers because you've got a wild personality clash if you go the dump-them-into-another-canon route and a boatload of potential artefacts from other canons.

Steven Universe

I love how this series seems like a mostly typical kids' fantasy/adventure show at first but really obviously isn't by the time you finish it. I also love how the characters interact and how the side characters have concrete enough lives outside of helping Steven and the Crystal Gems that they can (and occasionally do) have episodes dedicated to that. Also, the music. I'm a sucker for music.

Requests: Requests are repeated in different sections. There is one 3-way crossover prompt.

Hello writer person,

I'm fairly new to exchanges. I fully accept that I might be crap at this, but I'm going to try my best. Feel free to ignore anything in this except for my DNWs; I have a wide variety of tastes and might enjoy anything you write. I'm not picky.

Hard Do Not Wants:

Explicit sex.
Gore

Would rather not receive:

Stuff centered along romantic relationships.
Endless angst; some resolution or happiness would be nice.
Wildly ooc characters (unless it's deliberate crackfic).

Likes:

Fluff
Darkfic
plot and worldbuilding
Non-romantic relationships, healthy or not.
character studies involving how a character's past shaped their decisionmaking.
badass women

Avatar: the Last Airbender
I love this show. The worldbuilding, the themes, the character arcs... Anything focusing on their lives not during the war would be nice.

Zuko: Zuko has one of the most realistic and amazing arcs in the entire series, which also makes him one of my favorite characters. Admittedly, he's more like the favorite teddy bear with stuffing hanging out than the treasured baby doll, but I still love him. He tries so hard to live up to various people's expectations and fails so badly most of the time. All of the angst and hurt/(comfort optional).
Dealing with issues as firelord

More of Zuko as a child
Zuko gets kidnapped and has to be rescued by someone else.
Zuko gets kidnapped and has to save himself.

Suki: Suki is my favorite character in this show, hands down.

Her training before the war
Her life after the war
What happened while she was in prison?

Iroh: the badass grandpa who technically isn't their grandpa. I find him interesting because he is a mentor that doesn't die, is a reminder of the past, and shows a lot of inner strength and determination that the Fire Nation elite have but directs it at a completely different outlet.

raising Zuko
having to deal with Lu Ten's death
trying to be a good person in general

Toph: she is badass. I have a well-known weakness for badass female characters.
trying to keep her skills secret from her parents
her life during and after the war

Steven Universe
Another show that balances fluffy kid stuff and darkness. Things featuring the gems not having issues but subcriptions would be greatly appreciated.

Amethyst: I like her because she acts and looks exactly how she wants to be, even if others don't approve.

finding her at the Kindergarten
her life before meeting the other Crystal Gems
her feelings surrounding Rose's death

Garnet: another "I'm exactly how I want to be" character.

her internal dialogue between Ruby and Sapphire
learning to be a leader
futurevision

Ruby: I love this little square of anger, though I'm unsure why.

dealing with being separated from Sapphire
fighting

Sapphire:

learning to control her powers
using her futurevision

Pearl: Pearl deals with a lot of self-confidence and anxiety issues, which I get. She really cares about Steven and is really interesting when she's put aside her issues, admitted her feelings, or found an immediate goal. Her engineering is also quite cool.

repercussions from the Sardonyx incident
dealing with Amethyst
trying to be a good mother to Steven while still mourning Rose.

Connie: I love her character arc. She's a bookish girl who also gets to be extraordinarily badass and a major supporting character in her own right. I especially like that while she is a bookworm, reading and school aren't her only interests.

repercussions from Nightmare Hospital
just being geeky
fighting my Steven's side in a battle

Lapis Lazuli: Lapis is really interesting because her offscreen character arc shifts her alignment so radically; she goes from not caring about earth at all to sacrificing herself to protect it (and Steven), and we don't really get to see how she got from Point A to Point B.

her time in the mirror
her life before she got trapped in the mirror
adjusting to life on Earth

Ouran High School Host Club
I don't really have prompts for this. Sorry. My friends got me to watch it on a dare and I loved it. It's really funny and original. I really like Haruhi (me and competent female characters) and the twins (they give me a Weasley vibe). On an incredibly cracky crossover/AU note, the tins and the Weasley twins interacting would be hilarious.

Hello, Every Woman Creator.

I'm NotYourNormalFangirl over on AO3,

DNW: major character death, lots of angst, smut, unhappy endings.

My interests can more or less be summarized by women being badass.

Harry Potter:
McGonagall - Mother Bear McGonagall is my trope, though I'm also interested to see if someone could do a piece where she recognizes and/or works against her flaws (namely, occasionally blind loyalty to Dumbledore).
Hermione - I love it when Hermione is confident in her skills and competent at what she does. Anything involving either of those would make me happy.

Fullmetal Alchemist: Brotherhood:
Olivier Armstrong - she is my favorite character. I'm curious about the politics at Fort Briggs, especially before the Promised Day and/or with Miles during the Ishvalan Civil War.
Izumi Curtis - another character I love. I would like someone to write a fic where she saves (possibly young) Ed and Al.

Discworld:
Polly "Ozzer" Perks & Maladict - anything with these two (and possibly the rest of the regiment), really.

Babylon 5:
I love this show, but do not feel comfortable enough to write it. Anything would be fine.
