In anticipation of the guide, here's some alt predictions/wishlist/nonsensical suggestions for the characters we don't know yet. Not gonna bother with pics this time, still salty about the massive list I made that got blitzed by the host site changing policies to something more shitty. Note that I lack the affinity with Capcom characters to come up with solid suggestions.
Amaterasu: Shiranui
Arthur: Lancelot
Chris: Warrior Costume from RE5, I prefer a full fledged Safari, but that got a halfassed alt already
Chun Li: Kristen Kreuk Street Fighter movie Chun-Li obviously
Felicia: I dunno...a nun outfit!
Haggar: Suited up, with a mayoral sash
Hsien Ko: two conjoined Nemeses
Spencer: no brainer, OG Spencer
Trish: Gloria
Tron Bonne: Rush the Megadog
Viewtiful Joe: Uhm..The Green Ranger
Zero: MEGA NOVA CORPS
Vergil: Corrupted
Nemesis: Amingo
Firebrand: I dunno some form he had in Demon's Crest that's not represented yet
Phoenix Wright: hobo
Deadpool
Dormammu
Hulk: Maestro
Iron Man: War Machine
Magneto: wish he'd gotten a full version of that white alt, but King of Spain ripoff Magnus please
Phoenix: Jim Lee version
She Hulk: lawyered up
Spider-Man: much to choose from and somehow racking my brain, I kinda like the new Scarlet Spider costume
Taskmaster: UDON Task
Thor: Eh repped already but I really want a full-fledged Ultimate Thor
Wolverine: JEEEEANs
Nova: Darkhawk, but probably the much suckier classic Nova costume
Gonna play some vanilla now, posting this incomplete so that I don't lose it.
