That is so unfair, you paired up a man with a flamethrower, and a rocket launcher with a behemoth that crushes fighter planes against Spidey, a guy who can shoot web, and Captain America, a guy who's weapon is a shield.
I think that Spidey and Captain America would win because they are a lot more copperative while you got Ironman who would try to take all of the action while the Hulk would try to kill Iron /man
