Well i was reading ultimate Xmen vs The Ultimates and Collosus was beating the crap outta Thor until hawkeye interevened and hit him with a small nuclear bomb arrow, not killing him. So i mean if he can beat on Thor pretty easy for 10 mins then i would say Collosus takes this one. But Iron Man has 100 class strength, wich i was recently informed of. Collosus only has 80 or something i think so Iron man has got more strength, repulsor blasts, flight and a pretty durable suit of armour so to be honest Collosus would have a hard time and im not sure now who would win now lol. Probably Iron Man lol
