I'm surprised how decisively people are giving the win to Wonder Woman.
Iron Man is surely no pushover. He's had a tie with Silver Surfer, has battled Hulk, has battled Thor, has battled many top-tier characters and although he doesn't always he win he often has good showings.
Not only that, in this scenario he has War Machine to back him up.
But hey, the people have spoken. Looks like Wonder Woman takes this without much struggle.
Iron Man can hang with heavy hitters too. He also has offensive capabilities built into his armor that are more subtle than punching and kicking. Plus he's not alone in the fight.
Not trying to change your mind, this is just me stating facts on the other side of the fight.
Diana wins but it isn't as cut and dry as everyone is trying to make it seem. Tony and Rhodes have years worth of experience working together, Both of them know each others' abilities and weaknesses, and both have versatile weapons that can hurt top tiers.
I feel like where Iron Man lacks in speed, he gains an advantage with his teammate.
Where Wonder Woman gains with her reflexes, Iron Man gains with his endless gadgets to disrupt and annoy. Combine that with War Machine's endless barrage and I'd say you have a pretty solid match up.
