I think the point in asking was to fit the attributes of the consoles to the superheroes, not color code them, that's 4 year old stuff.... "Well, the Xbox is green, so it should be green lantern..." Nice and well thought out, we need a thread for that....
Anyway...
XBOX 360: Spider-Man: Everyone knows him, has super powers. Not the strongest, but, still well known.
PLAYSTATION 3: Akuma (Gouki): Strong as hell, and whips could whip the crap out of anyone, but, not exactly everyone's favorite.
Wii: Nathan Drake: (LOL) Doesn't have any powers, and isn't strong, but, relies on what's avaliable to him to destroy the competition. And gets the Chicks.
