Gor is a monstrous beast that is a pet of General Grievous and a villain in the Star Wars series.
He is one of Grievous's pets that the General actually cares for. Gor was founded by Grievous during his warrior days and brought him when he joined Dooku. Grievous planted cybernetic technology to Gor. He had Gor live in his castle and let his medical robot take care of him while Grievous is on his missions.
When Kit Fisto infiltrated the Grievous's castle, he sends Gor to kill the intruders. Kit Fisto kills Gor by impaling him with a lightsaber. Grievous checked on Gor's progress and was upset over his death.
