Iron Man (Marvel)

Iron Man, or Tony Stark, is the main hero of a comic by the same name. Stark: an inventive genius, industrialist, and multi-billionaire, went to Vietnam to oversee a field test for one of his transistorized weapons, that his company-Stark Industries made. While there he accidentally stepped on a bobby trap, and a piece of shrapnel became lodged in his chest. Injured, Stark was captured by Communist forces under Wong-Chu, and made a prisoner. While in prison, Tony created a mechanical suit of armor so that he could escape, as well as using his technological know-how to create a pace-maker like device to keep his heart beating and thus, Stark could stay alive. Using the Iron Suit, Stark was able to escape the Communist forces, and once back in America, he perfected his work, making a practically invincible iron suit much like he has today.

Powers
Although Tony Stark himself, doesn't have super powers, his armor gives him enhanced strength -allowing him to lift up to 100 tons- as well as flight via rocket boots. His armor is also equipped with the most advanced technology and weaponry to give him an advantage over the supervillains he battles.
