Warjak was a Feeorin gladiator during the early years of the Galactic Empire's reign who was declared champion of a contest known as the Outer Rim Carve-Up on many occasions. He was invited to take part in the Gladiator Night event hosted by a mysterious figure known only as The Commissioner on Lothal, where he faced the Houk gladiator Borbig Drob for additional pay. This rigged match was interrupted, however, by the arrival of the Commissioner's true identity, ISB Lieutenant Jenkes, who was being chased by the bounty hunter Bossk and his new companion Ezra Bridger. After Jenkes wounded him, Bossk requested to fight the two gladiators with his bare hands in combat, which Warjak and Drob agreed to, only for the Trandoshan to defeat them both.
