During the Galactic Civil War era, a male assassin named Kunn Kuroosh served High Inquisitor Mal Sikander within the ranks of the Inquisitorius. Tales circulated that he was a Sith sorcerer, and few individuals survived encounters with him. Following the Battle of Yavin (dated at 0 BBY), Kima Nazith, a member of the Alliance to Restore the Republic and Pooja Naberrie's bodyguard, hired a spacer to kill Kuroosh. Nazith suggested employing a thermal detonator against Kuroosh, who carried a red-bladed lightsaber with a design similar in design to that of Darth Vader's.
Kunn Kuroosh existed as a non-player character within the massively multiplayer online role-playing game Star Wars Galaxies: An Empire Divided. This video game was developed by Sony Online Entertainment, published by LucasArts, and released in 2003, before its servers shut down on December 15, 2011.
Reportedly, the game's data indicated that Kunn Kuroosh utilized the "lesser_prophet_of_the_dark_side" template. Consequently, his appearance was supposedly randomly selected from four possible appearances, including a male Chiss, a male Nikto, a female Twi'lek, and a male Human. However, a screenshot shows Kunn Kuroosh as a Human female, suggesting he might have used a different character template. Therefore, while his canonical species in the Star Wars Legends continuity remains uncertain, the quest dialogue referred to Kuroosh as male. The questline involving Kuroosh was later removed from the game.
