The Sullustan Ten Numb was initially a bounty hunter before joining the Rebel Alliance. He fought with the B-wing group Blue Squadron at the Battle of Endor, and was promoted to the squadron's leader following the engagement.

One week after the battle, Numb used his B-wing, modified to carry fire-suppression equipment, to combat fires on Endor caused by debris striking the moon. Shortly afterward, he accompanied Rogue Squadron members Luke Skywalker, Wedge Antilles, Tycho Celchu, and Wes Janson on a mission to Corellia. When the city the group was visiting was attacked by Imperial Storm Commandos, Numb attempted to chase the Imperial soldiers down, but was captured by their leader, General Weir. Numb was taken to Tralus, another planet in the Corellian system, where he was subjected to intense torture. Janson was able to locate him, but he had already succumbed to injuries by that time.
