The MCU's Oldest Villain Just Made a Surprise Return in 'VisionQuest'

In the 2008 movie Iron Man, the biggest, baddest villain was Obadiah Stane, played by Jeff Bridges. Originally business partners with Tony Stark (Robert Downey Jr.), Obadiah betrayed Tony by hatching a plot to kill him while he was in Afghanistan. When Tony survived and became Iron Man, Obadiah responded by taking on his own iron identity: The Iron Monger.
