The whole army of Halo would beat Iron Man,but Iron Man can beat master chief because he has better thecnology.
Ironman
spiderman and ironman
Iron Man
With gambits powers not being the most powerful it's my opinion that ironman would win, from a very long distance ironman could take him out. the only exception to this would be if gambit were to catch ironman without his suit on but the likely hood of gamit managing this is slim. i am a fan of both toons but it is ironman who would win this battle overall.
Iron man would.... Definitely
