Iron Monger

Background & Phase One
Obadiah Stane was the business partner of Tony Stark and a good friend of his father, Howard Stark. After Howard Stark's death, Stane became interim CEO of Stark Industries until Tony Stark took over officially shortly after. Stane's jealousy of the younger Stark led him to join forces with the Ten Rings to organize a failed attempt to assassinate him so Stane could become CEO once again. When this failed Stane created the Iron Monger Armor and attempted to kill Stark himself, leading to his own death.
