Dooze, a member of the Galactic Empire's Gamma Squad, was a stormtrooper. He was stationed on the forest moon of Endor, where he and the other members of Gamma Squad, under the command of Commander Altadan Igar, were tasked with locating the missing Theta Squad. Their search led Commander Igar to cross paths with the Jedi Knight Luke Skywalker, who had arrived with the intention of surrendering himself. Upon spotting Skywalker, Dooze aimed his blaster at him, maintaining his aim until Commander Igar instructed him to search the Jedi. Dooze confiscated Skywalker's lightsaber and gave it to Igar, inquiring whether it was a hand torch, as he failed to recognize the weapon. Skywalker was then questioned by Igar, and revealed that he was aware of the missing squad's location, explaining that he had previously encountered them and that they were all dead. Guided by Skywalker, Dooze and the rest of Gamma Squad proceeded for several kilometers until they reached the location of Theta Squad. There, Dooze discovered the body of his friend, the scout trooper Rell. Overcome with fury, Dooze attacked the unresisting Skywalker with his rifle, unleashing a series of strikes and verbal abuse. Commander Igar intervened, ordering Dooze to cease his assault, and the squad then escorted Skywalker back to their base.
