Iron Man (Tony Stark) is a genius billionaire weapons manufacturer who built a powered armor suit to escape captivity and became a founding Avenger. Created by Stan Lee, Larry Lieber, Don Heck, and Jack Kirby in 1963, Stark's arc from reckless arms dealer to self-sacrificing hero mirrors themes of redemption and responsibility. His quip "I am Iron Man" — spoken both in defiance and in sacrifice — bookends one of Marvel's greatest character journeys.
