The Iron Monger is an identity used by several fictional characters in the Marvel Comics universe, most of whom have been supervillains. The first and most notable person to use that identity was billionaire industrialist Obadiah Stane, who used the Iron Monger armor in the climax of a long-running conflict with his nemesis, Iron Man. Stane first appeared in Iron Man #163, and first appeared as the Iron Monger in Iron Man #200.
