A Tusken leader, URoRRuR'R'R was very adept at marksmanship and hunting, and also excellent in hand-to-hand combat with the traditional gaderffii. Unlike most Tuskens, he was not intimidated by machines and had no fear of approaching them. He acquired his hunting rifle, an important status symbol in Tusken culture, by scavenging it from the wreckage of a downed starship near Anchorhead. His group raided moisture farms for water and parts and roamed the Jundland Wastes, preying on unsuspecting travelers. After Luke Skywalker had C-3PO stop his landspeeder, and as they searched for the errant astromech droid R2-D2, URoRRuR'R'R sprung upon Luke with a vicious bellow, knocking the youth unconscious. As URoRRuR'R'R and his followers were beginning to strip Skywalker's vehicle for parts, Obi-Wan Kenobi showed up, expertly mimicking the call of a krayt dragon. As intended, this unsettled the Tuskens and caused them to flee the scene. However, as Kenobi warned his soon-to-be apprentice Luke, the Sand People would not remain cowed for very long.
