General Grievous
Leading the Separatists droid army in revolt against the Old Republic is the sinister cyborg General Grievous. The only organic parts left inside the enhanced droid frame are a brain, eyes, and few organs to keep the brain alive. Armed with a humanoid’s mind and the reflexes of a combat droid Grievous takes pleasure in the suffering of all organic life. Grievous has magnetic claws for feet and arms which can separate in two giving him the ability to fight with four weapons. He enjoys facing Jedi in single combat and keeps their lightsabers as trophies.
Obi Wan finally defeated Grievous after an epic battle on Utapau. After losing his lightsaber, Kenobi resorted to the “uncivilized” method of shooting Grievous with a discarded blaster. The shot pierced the general’s damaged torso and hit his gut-sack. Volatile fluids inside ignited and Grievous burned to death.
