James "Rhodey" Rhodes / War Machine

James "Rhodey" Rhodes / War Machine (Don Cheadle)

It's not easy standing in the shadow of a modern Leonardo Da Vinci, but James Rhodes does it with pride and loyalty. One of Stark's closest and oldest friends, Rhodey helps mitigate Tony's strained relationship with the United States military.

Often aggravated by his friend's cavalier lifestyle and with Tony's insistence that the suit remain only his, it remains to be seen if Rhodey believes there is anyone more responsible to pilot this revolutionary weapon. via Marvel
