The group of individuals working for Khel Tanna was under the direction of the rogue Khel Tanna. This team was made up of Tanna, T'onga, Akko, as well as Ooris Bynar.
Sometime between approximately 8 BBY and 2 BBY, the crew executed a heist for the Hutt crime lord Jabba Desilijic Tiure. During this operation, the smugglers Han Solo and Chewbacca intervened, preventing the crew's capture in shackles. Following the heist, Tanna told Jabba that Solo and Chewbacca had compromised the crew's meeting point, nearly resulting in their deaths.
Tanna established a fresh version of her crew by absorbing T'onga's crew. After becoming dissatisfied with T'onga's leadership, Bossk'wassak'Cradossk, Deathstick, and Durge consented to Tanna taking over as the new leader.
