Each battle requires that you defeat all three characters from the opposing team. This is a fighting game where you pick any three characters you want to form a super team. What really makes Marvel vs Capcom 2 so fondly remembered is the combat. Each character has various colors as well so the roster is the most diverse the series has ever seen.
You have various Avengers, X-Men and Spider-Man characters as well as people from franchises such as Street Fighter, Darkstalkers, Mega Man, Resident Evil and more.
