Iron Monger is an alias used by multiple fictional characters, supervillains appearing in American comic books published by Marvel Comics. The most well-known version, Obadiah Stane, first appeared in Iron Man #163 (Oct. 1982), and the Iron Monger armor first appeared in Iron Man #200 (Nov. 1985). The Iron Monger armor, manufactured by Stane International and code-named I-M Mark One, is an armored battle-suit of "omnium steel" (a fictional alloy), containing various offensive weaponry including a powered exoskeleton that amplifies the user's strength, repulsor rays fired from the gauntlets, and an intense laser beam housed in the battle-suit's chest unit. The suit provides the user with the ability of subsonic flight, thanks to magnetically powered turbine boot jets. Since the Iron Monger armor was based on a modified version of Tony Stark's Iron Man design, the Iron Monger's abilities are very similar to the original red and gold armor, but with increased power. The repulsors are more powerful and the Iron Monger is also larger than Iron Man's armor. It is presumably proportionally stronger as well. The Iron Monger (unlike the Iron Man armor) is also externally computer controlled. Stane attempted to use the remote control to compensate for his lack of experience in using the Iron Monger armor – a vulnerability Iron Man exploited in disabling.
