An American billionaire playboy, industrialist, and ingenious engineer, Tony Stark suffers a severe chest injury during a kidnapping in which his captors attempt to force him to build a weapon of mass destruction. He instead creates a powered suit of armor to save his life and escape captivity. He later uses the suit and successive versions to protect the world as Iron Man. Through his corporation ― Stark Industries ― Tony has created many military weapons, some of which, along with other technological devices of his making, have been integrated into his suit, helping him fight crime.
Pepper Potts
Stark notes that Potts, his secretary/personal aid, is virtually the only real friend he has at the company. Pepper is promoted to CEO of Stark Industries. She later attempts to resign after Tony finds a cure for the palladium poisoning that was killing him but he does not accept it. At the end of the film, Pepper becomes Tony's girlfriend and partner. In The Avengers, Potts is instrumental in helping with the development of Stark Tower, the new upgraded arc reactor, Tony's assistance to S.H.I.E.L.D.
