16. Tony Stark

Since we mentioned him earlier, we can argue that Tony Stark's Iron Man should be on this list, despite of the fact that he ranks among the most over-powered superheroes. But even as he goes toe-to-toe with The Hulk, he does it by using his own human abilities. As one of the most brilliant minds in the Marvel Comic Book Universe, he builds armors to suit all occasions.

Of course, you could say that his armor is made predominantly from non-existent materials and is able to do impossible things. However, Stark has consistently demonstrated that he’s more human than the others on this list.

We should add that James Rhodes, who becomes War Machine with Stark's technology, deserves a spot here, as well. As his name implies, War Machine is a war-ready version of Stark's friendlier armor.
