Klepti B'ay was a Jawa on Tatooine whose clan picked up the wreckage of a Rebel spaceship as salvage. Unbeknownst to them, a dark trooper aboard was in working condition. After freeing itself of the wreckage, it killed most of the Jawas aboard the sandcrawler. The uncontrolled sandcrawler crashed into the Mos Espa Grand Arena, leaving Klepti B'ay the only Jawa to survive, and nearly killing nearby mercenaries Gizman, Spiker, and Onoh.
