In the animated series Star Wars: Clone Wars (2003–2005), Dooku is portrayed by voice actor Corey Burton and is the main antagonist of the series. During the series, he leads the Separatists in attacks upon the Republic. He also sends Dark Jedi Asajj Ventress (Grey DeLisle) on a mission to kill Anakin Skywalker — Sidious' ploy to test the young Jedi's worth as an apprentice — and trains General Grievous in lightsaber combat. In the series' final episode, he orchestrates an attack on the planet Coruscant in which Grievous kidnaps Palpatine, setting the stage for Revenge of the Sith. Dooku is also one of the main antagonists in the television adaption of the movie Star Wars: The Clone Wars.
