Ror was a Zabrak male, who during the Clone Wars, fought for the Confederacy of Independent Systems as a Dark Acolyte. He utilized a red double-bladed lightsaber that bore a resemblance to the one used by Darth Maul.
Alongside fellow Dark Acolyte Kern, he spearheaded the Attack on Kashyyyk during the Clone Wars' initial year, supported by trandoshans. Their primary mission was the destruction of the Jedi Outpost located on the planet and the capture of Mavra Zane along with her Padawans. After successfully capturing Master Zane, the pair gave chase to the Star Runner in Star Couriers as it attempted to breach the Separatist blockade. Regrettably, they were unable to fully achieve their secondary objective. Subsequently, they relocated the combined Trandoshan and Confederate Fleet to Felucia.
During the Felucia Rebellion, Marva Zane, together with her Padawans, was recaptured and condemned to execution at the Ancient Abyss. Ror and Kern were present, along with the Presidente of the Commerce Guild, Shu Mai. With assistance from Yoda and the Star Runner, the Jedi managed to free themselves. Shu Mai made her escape, leaving Ror and Kern to confront Marva and her Padawans. Sadly, both Dark Acolytes met their demise in the ensuing battle.
Their sacrifice allowed Shu Mai to flee with her fleet and initiate an Invasion of Coruscant. These two Acolytes were not the final Zabrak disciples of Count Dooku; a year later, Count Dooku journeyed to Dathomir to seek a new apprentice to take the place of Asajj Ventress.
Ror makes an appearance in the Jedi Destiny segment of the 2012 Kinect-exclusive video game, Kinect Star Wars. He is also featured as one of the lightsaber duelists. In the game's credits, he is credited as Darth Ror. However, within the game itself, he is not addressed by the Darth title.
