"I am Iron Man, the suit and I are one" - that's what Tony Stark once said. Iron Man basically is the name of the suit armor created by Tony Stark.

Anthony Edward "Tony" Stark was born in New York and is a billionaire industrialist and inventor. He runs Stark Industries, originally started by his father, Howard Stark. While in Afghanistan, Tony was captured by Ten Ring, who ordered him to build the Jericho missile for them. Instead Stark, with Ho Yinsen, used their resources to build a suit of armor and make their escape. Returning to America, Stark improves his armor and becomes the superhero Iron Man.Stark is still human, with the exception of an Arc Reactor in his chest.
