A Human Knight from Zakuul's Eternal Empire, Zotar was a male individual. As the Exarch governing the Old World, he was also a combatant in the Arena Grand, earning monikers like "The Bringer of Death", "The High Justice of Pain", and "The Emperor of Agony". In 3630 BBY, Zotar was known as the Arena's Eternal Champion; a title that led to a challenge from "the Mysterious Stranger." During the tenth and final round of the Arena battles, Zotar fought his challenger within After Shock, which was a stolen Galactic Republic walker, but he was ultimately the loser.
