This is probably the closest we'll ever get to seeing Mega Man in Ultimate Marvel vs. Capcom 3 (UMvC3).
If you only saw the picture (after the jump), you'd probably be thinking, 'Finally, Mega Man is in the game,' but the reality is ... not really.
Global-Trance (via Event Hubs) have posted images for DLC alternate costumes in UMvC3.
That means it's not Mega Man you are seeing, it's Zero.
See Zero as Mega Man below.
The DLC alternate attires in UMvC3 were leaked because the content is already on the disc.
Earlier this year, Global-Trance hacked into MvC3 and revealed DLC characters Jill and Shuma-Gorath were playable on the disc. Jill was partially completed while Shuma-Gorath was finished.
