Count Dooku is a fictional character from the Star Wars franchise, appearing in Star Wars: Episode II – Attack of the Clones and Star Wars: Episode III – Revenge of the Sith (portrayed by Christopher Lee). He was also voiced by Corey Burton in the animated series Star Wars: The Clone Wars.
Once a respected Jedi Master, he falls to the dark side of the Force after the death of his former apprentice, Qui-Gon Jinn, and becomes Darth Sidious' second apprentice under the name Darth Tyranus. As the founder of the Confederacy of Independent Systems, he instigates the Clone Wars. Dooku was trained by Yoda as a Padawan learner.
Introduced in Star Wars: Episode II – Attack of the Clones, Count Dooku appears as the leader of the Confederacy of Independent Systems, a federation of planetary systems rebelling against the Galactic Republic. He says that the Republic is corrupt, and that its politicians are more interested in maintaining the bureaucracy and enriching themselves than in helping poor, oppressed systems.
Dooku recruits bounty hunter Jango Fett to assassinate Padmé Amidala on Coruscant; the attempt on her life fails, however. When a fight with Obi-Wan Kenobi forces Fett to flee from Kamino to Geonosis, the bounty hunter rendezvous with his benefactor. After capturing Obi-Wan on Geonosis, Dooku tells him that he's attempting to save the Republic, explaining that thousands of senators are under the influence of a Sith Lord named Darth Sidious. When Obi-Wan refuses to join him, Dooku promptly sentences him to death.
