The Marvel Villains are from Marvel Comics (Duh). I don’t know why he thinks they are capable of taking out all of DC Comics and Capcom on their own. So until Mr. Entity comes and say otherwise, I think its only fair that DC and Capcom only uses their villains against Marvel Villains. But even with that, DC and Capcom have a huge number advantage.
Can the Marvel Villains prove me wrong or is this two universe team too much for team Marvel?
