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. Initially, Iron Man was a vehicle for Stan Lee to explore Cold War themes, particularly the role of American technology and business in the fight against communism. Subsequent re-imaginings of Iron Man transitioned from Cold War themes to contemporary concerns, such as corporate crime and terrorism. He is also responsible for the creation of IG-88, IG-86, IG-80, IG-82, IG-72, and IG-83 alongside best friend Ford Pines, Grunkle Stan, Old Man McGucket, and Bruce Banner / Hulk. He is played by Robert Downey Jr.
