Cad Bane was a Duros male bounty hunter in the galaxy during the Clone Wars. He was considered the leading bounty hunter in the galaxy during the Clone Wars due to the death of Jango Fett at the First Battle of Geonosis in 22 BBY. Although his infamy grew during the Clone Wars in particular, Bane had a high standing amongst other bounty hunters, working with the likes of Aurra Sing years before the onset of the war. He even had a temporary alliance with the Sith Lord Darth Maul. He specialized in fighting Jedi and did battle with some of the most skilled Jedi during the Clone Wars, including Obi-Wan Kenobi and Anakin Skywalker. His reputation led him to be repeatedly hired by the Sith Lord Darth Sidious, working for him on numerous projects, infiltrating the Jedi Temple to steal a kyber memory crystal containing a list of Force-sensitive children throughout the galaxy.
Bane was eventually hired by Jabba the Hutt to free Jabba’s uncle, the gangster Ziro Desilijic Tiure, out of Republic prison. After a successful mission, Bane was re-hired to track down Ziro when he fled. Bane found Ziro dead on Teth and eventually dueled Kenobi and Quinlan Vos, using a variety of weapons to hold his own against the two Jedi before fleeing. Later into the war, Bane was brought in by Count Dooku to participate in the Box, surviving the deadly challenge before being appointed the leader of Dooku’s plot to kidnap the Supreme Chancellor. However, their plot failed when it was revealed that Kenobi had infiltrated their ranks, disguised as Rako Hardeen, and Bane was arrested along with the rest of the group.
