Cad Bane first appears in the season one finale "Hostage Crisis", where he infiltrates the Senate building on Coruscant to hold senators hostage in exchange for the release of Ziro the Hutt. It is revealed in season three that he was hired by Jabba the Hutt to extract Ziro due to an incriminating datapad the latter possessed, and he is hired in the episode "Hunt for Ziro" to track and capture the rogue Hutt, but he is instead assassinated by Sy Snootles.
In the second season, Cad Bane is contacted by Darth Sidious for a special assignment: the capture of a Holocron from inside the Jedi Temple. Bane finds himself in a massive struggle for the stolen Holocron as Skywalker and Ahsoka Tano attempt to take it back. He is briefly captured before leading Obi-Wan Kenobi and Mace Windu into a trap in his headquarters, allowing him to escape.
During the fourth season, Cad Bane is revealed to be in a Republic prison. He is then hired by fellow convict Moralo Eval for a job by Count Dooku to kidnap Chancellor Palpatine on Naboo. However, Kenobi poses as bounty hunter Rako Hardeen and manages to foil the plot even though Dooku escapes while Bane was arrested.
He appears after the General Grievous fight on Geonosis and appears after you take TD-54 to the Jedi Council he steals TD-54 and you must chase him through the sky and then through the city of Coruscant he escapes but leaves TD-54 Behind.
