Mister Bones, also simply referred to as Bones, was a heavily modified B1-series battle droid with a murderous personality. He was constructed by Temmin Wexley and built from components the boy scavenged from the catacombs beneath Myrra, the capital city of Akiva. Bones served as Temmin’s personal bodyguard in addition to being considered his friend and loyal companion. He had a sadistic personality and would sing or hum while attacking and maiming his victims. After Temmin reunited with his mother, Norra Wexley, Temmin joined the nascent New Republic and helped Norra and her team hunt down Imperial war criminals.

Mister Bones continued serving Temmin a year after the Battle of Endor. When Princess Leia Organa enlisted the services of Norra and her team in finding her husband, Han Solo, Bones accompanied them to Irudiru and later Kashyyyk. He took part in the liberation of the Ashmead’s Lock prisoners which included Temmin’s father, Brentin Wexley. Bones continued supporting his master Temmin during the lead-up to the attack on Chandrila. Following the attacks, Bones accompanied Temmin and Norra’s team in their hunt for the Imperial Grand Admiral Rae Sloane.

At the request of Temmin, Mister Bones followed the boy’s mother to Jakku. He rescued her from an Imperial labor camp. After reuniting with Jas Emari, Bones escorted the two women on their hunt for Grand Admiral Sloane. During the Battle of Jakku, Bones along with Norra joined forces with Sloane and Brentin to stop Counselor Gallius Rax from detonating both Jakku and the New Republic and Imperial forces. Bones later separated from Norra’s party and reunited with Temmin during the battle. He saved the boy from several Imperial stormtroopers but was permanently disintegrated in a friendly-fire incident by two A-wings.
