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.

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.
