About

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 - Stark 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.
