long list sorry
Yeah, I totally understand the non-movie thing. DCverse, I usually play next-gen originals, although I have played Ten from Batman Beyond, Cassandra Sandsmark, and Batman (this would be a little rusty, it's been forever). I haven't had much of a chance to flex this muscle. I don't know many people who play DCverse stuff, but I know a ton who play Marvelverse (comic or movie).
Star Wars are all original characters. I'd have to rewatch the original series to play anyone from it, and it'd probably just be Leia. I haven't seen the new ones or read any of the books, but I've been in an OC game and have some homeless characters from it. They're from a time way after everything.
I don't play anyone specific from the Star Trek fandom, but I'd be willing to give it a try as long as it was TOS, TNG, Voyager, or Nu.
In Final Fantasy, I can play Lenna (FFV), Celes, Relm, Yuffie, Shera, Elena, Marlene, or an original (I was in a game for a long time and have several). Selphie, Quistis, Librarian, and originals (another game for over a year here). Garnet and Eiko. Yuna, Rikku, or Lulu. FF10's a bit iffy, I never actually finished any of the FF10 games, so I'm not exactly sure how everything gets thrown together. I also play Alma or Ovelia from Tactics (for PSX). I can throw in an OC there since the majority of major players are men with the exception of Reis, who has very little information, but if you wanted to play against her, I could probably do that too.
