Gorbus was a male Human Sith Marauder living at the time of the Jedi Civil War.
In 21,108 AR he resided in the Trayus Academy on Malachor V as a member of the Remnant Sith Order. When the Galactic Republic launched a surprise attack on Malachor, the academy was mostly destroyed. However, Gorbus was among the survivors who escaped to the nearby Singularity Base, along with his friends Yaiban Retwin and Zanjo Fel, as well as Headmaster Thoriel Silbus. As Republic troopers invaded the facility, Gorbus was tasked with hunting down and slaying a Jedi who was among them.
Gorbus eventually found his prey, the Padawan Kaevee, and chased her through the inner control rooms of the facility. Bereft of a lightsaber, the Jedi defended herself with various telekinetic attacks as well as her pet laigrek. The Sith Marauder was more than a match for her, suffering only slight injuries and badly wounding the laigrek. Enraged and frustrated by the Jedi's evasiveness, Gorbus at last cornered her in a hallway and threw his lightsaber at her. Kaevee managed to duck under the flying blade, which cut into a machine behind her and was lodged inside. Before Gorbus could recover his weapon, the Jedi drew a blaster pistol and shot him dead.
