ok re write the stamina of the fighters and mc is genetically enhanced

you assholes havent you read anything about master chiefs armour ok its like this iron man could win without guns cuz he can fly but master chiefs armor is highly more advanced and realy if it all it says it is he could not get hurt by iron man but out of the armors master chief would win cuz hes geneticaly advanced bun in armor its pretty even it all would depend on the terrain the weather the  health of both the fighters and how much luck each one can get his hands on

You can't say "If they're not in their armor" If they're not in armor they're not the characters! They are just John vs. Tony Stark!! We're talking in their armor which is what makes them the characters.

master chief  all the way brother he kicks but in every halo game

My brother was watching a Marvel cartoon and there was a question for kids to answer of who would win in a fight between Iron Man & Magneto...and, I have a picture of this as proof, a kid wrote in saying "Iron Man might win because Magneto can only control metal and Iron Man is not made of metal. He's made of Iron."

Daytime televison.

better question, who would win ironman or gordon-ramsey master chef?

master chief dont need armor, hes fast and agile and would probably destroy iron man, for instance in the first iron man, the bigger suit killed him in the end, imagine something with the strength and super agility of the bigger suit in one..

dont forget though...master chief has luck.

Master Chief wouldn't stand a chance. Sure, he might have advanced guns, but his armor is waaaayyy weaker than Iron Man's.

there is not even a question there!! Iron man all the way.
