Gameplay wise Bison would be amazing. But it would be Ryu or Chun-Li. Maybe pushing Akuma instead of those two, since Capcom like (or liked) giving him cameo appearances (and alternate forms). --- Expect sales to go up in Japan if the Marvel vs Capcom 3 trailer has Jill caught in [Shuma-Gorath's] Chaos Dimension. - DrunkenPilot72
Seriously though, Chun Li would've been better if this came out around the time of her movie, but not now.
And actually, if you we're going to look for a rep for PSASBR I think you should focus on more the SF Alpha games and what came with those, so I think Akuma would be more appropriate. I associate Ryu Ken Chun Li etc more with the arcade / SNES --- PSN, WiiU, and Apple GameCenter IDs: Saffahh PSASBR: Red Belt, main E.Cole, alt Nariko, Twing-Twang baby!
