General Grievous, was a cyborg and the Supreme Commander of the Droid Armies of the Confederacy of Independent Systems during the Clone Wars.
His body was a fusion of a powerful robotic structure and an organic brain, nervous system, and sensory organs. Brilliant golden eyes with black, reptilian pupils and red-raw sockets were the only visible reminder of his organic past.
Grievous was a cold and calculating general, a brilliant strategist, and a cunning military mastermind. He was known as one of the greatest Jedi hunters and a collector of the lightsabers of fallen Jedi, which he used in battle with his foes.
