Gor was a male roggwart whom Kaleesh General Grievous of the Confederacy of Independent Systems kept as a pet during the Clone Wars. Gor guarded his master's fortress on the third moon of the planet Vassek; he was tended to by the medical droid EV-A4-D whenever Grievous was away. Gor's body was covered in thick armor; on his back were four cybernetic limbs.
After Count Dooku allowed a Republic task force to infiltrate the lair of General Grievous, the cyborg ordered Gor to kill the intruders. However, the roggwart was killed by Jedi Master Kit Fisto and his apprentice Nahdar Vebb.
