Why can't I get Akuma to pop in Marvel vs. Capcom 2 XBLA?

[thespider1]

I wanna fight Akuma in arcade (not onlinie, I still suck too much. And not in training, i want him to actually fight back). I realize the opponents in arcade are randomized, but Akuma NEVER pops up. Is there a reason for this? Does something special need to be done to fight him in arcade? Or do some characters just never show up as opponents in Arcade mode?

Is there this problem w/ UMVC3?

I think the opponents that pop up somewhat depend on who you're selecting, so try mixing your team up some.

There also might be a way to get training dummies to fight back, at least there usually is in fighting games.
