A male Tusken Raider named A'Vor belonged to the tribe led by A'Yark. He was related to A'Koba as his cousin, and also had a twin brother.
During the Galactic Civil War, A'Vor resided on the Outer Rim planet of Tatooine, where he was a member of Chieftain A'Yark's tribe. Not long before the Battle of Yavin, A'Vor, alongside his twin brother and cousin A'Koba, participated in the killing of a young krayt dragon as part of an initiation ritual into adulthood. Following this, he asserted to A'Yark his capability to slay the fully grown krayt dragons too.
After A'Koba rendered Luke Skywalker unconscious, he, along with his twin and their cousin A'Koba, commenced a search of Skywalker's landspeeder. Obi-Wan Kenobi, a Jedi Master, frightened them away by imitating the sound of a krayt dragon, causing A'Vor and the other Tusken Raiders to run away.
