IG-101 was one of the two IG-100 MagnaGuards, the other being IG-102 that served as General Grievous's droid bodyguards aboard Invisible Hand during the Battle of Coruscant. He engaged Jedi Master Obi-Wan Kenobi in combat and was beheaded early on in the fight, but remained functioning and able to fight. Eventually, however, Kenobi managed to get inside the MagnaGuard's guard and cleave him in two; his body fell apart with a metallic groan, still grasping feebly at the Jedi.
