Gor

Gor was a male roggwart owned by General Grievous during the Clone Wars. Grievous, who served as the Supreme Commander of the Confederacy of Independent Systems' Droid Army, kept Gor in his castle on the third moon of the planet Vassek. There, Gor acted as both a guard and a pet for the general, and was one of the few creatures Grievous cared for. While the general was away, Gor was tended to by his master's medical droid, EV-A4-D. The droid was responsible for fitting Gor with four cybernetic limbs grafted to his back, and attaching an exoskeleton of armor to the roggwart's body.

In 22 BBY, the Confederate Head of State, Count Dooku, lured a Jedi-led Republic task force to Grievous's castle in an attempt to test the general's skills. Grievous ordered Gor to kill the intruders, but the roggwart was slain by Jedi Master Kit Fisto.
