Marvel's got the likes of Galactus, Dark Phoenix, Dormammu, and even the god of hyperbole Shuma-Gorath. I don't know who the most powerful beings in Capcom would be (barring game play mechanics, obviously). I'd imagine it would be Amaterasu and the devil forms of Dante and Virgil, but I could be wrong.
