Two for One - Crossover and Fusion Mini-Challenge
Two for One is an annual mini-challenge to help people who like crossovers and/or fusions find one another's requests.
To participate, simply copy-paste the following into a comment:
AO3 Name:
Letter Link:
Crossover Type: (ie. crossover, fusion, or either)
Applicable Requested Fandoms:
Potential Crossover Fandoms: (you may list specific combinations you're interested in, ex. Megamind/Treasure Planet, or generally request any of your Yuletide requests with each other, or list additional fandoms you'd be happy to have crossed with any of your requests)
Prompts/Optional Details: (as many and as detailed as you like)
One of the fandoms in each crossover or fusion prompt must be one you are requesting for Yuletide; however, the other doesn’t have to be. It doesn’t even have to be in the tagset at all!
Some clarification about crossover types:
Crossovers tend to involve Fandom A's characters interacting with Fandom B's characters or worldbuilding, with everyone retaining their canon backgrounds. Ex. Aurora and Red Riding Hood team up to defeat a villain, or Clark Kent falls into a portal that takes him to Tortall.
Fusions tend to be AUs in which Fandom A's characters have always existed in Fandom B's setting instead of their own, often replacing Fandom B's characters. Ex. Pacha and Kronk as contestants in the Hunger Games, where Kuzco and Yzma are referees. (A fic like this in which Hunger Games characters also appear would be a hybrid between a fusion and crossover.)

Crossover Type: crossover
Applicable Requested Fandoms: Rivers of London, Caprica (TV), Sense8
Potential Crossover Fandoms: Any fandoms I've written before (https://archiveofourown.org/users/Beatrice_Otter/pseuds/Beatrice_Otter/)
Prompts/Optional Details:
RoL/Young Wizards: Wizardry is so different in these two series, how do you reconcile it? How do they fit together? What would happen if Peter was investigating the same problem Nita and Kit were investigating?
RoL/The Old Guard: There are lots of different types of immortal (or, at least, really old) people in the RoL universe. How do the Old Guard fit?
RoL/Terminator: If Judgment Day happens, and Terminators have microchips, all of a sudden being a wizard is a superpower to save the world. On the other hand, what if Sarah and John et al ended up in Britain and got tangled up in a case? What would Peter make of time travel?
Caprica/Battlestar Galactica: is Tamara-A still around in some Cylon computer system somewhere during the Cylon war? What does she think of the Final Five? Does she ever get a chance to meet Bill Adama?
Caprica/Murderbot Diaries: Tamara would be horrified by the Cylon war. So would Murderbot and ART. I wonder what their perspective on Tamara would be, and also, remember how the Centurions in BSG have those little doohickies in their heads that force them to obey the skinjobs? Isn't that like a governor module? What would Murderbot do? Are the colonies a lost colony that ART is trying to contact and save from invading corporates?
Caprica/Imperial Radch: Tamara is the opposite of Breq. (Human consciousness uploaded to a computer, instead of a computer consciousness downloaded to a human body.) And the Cylons rising up and killing humans would be anathema to Breq and any AI of the Radch.
Sense8/Rivers of London: What if they run into Peter while on the run? or what if somehow Wolfgang has come up against Tobias Winter in some previous brush with the law? The same sort of people who would experiment on telepaths also seem to me to be the sort of people who would experiment on fae.
