Storm vs. Colossus
The two heros' that are designed to defeat 100 class people.
One would be designed by nature(Storm); the other by science(Ironman).
Despite what some people have said on here about Colossus; he does need to breath. It's Juggernaut who don't.
I think Ironman would defeat Storm; but I fig. Storm would wrap it up for Colossus.
