how does count dooku die in the clone wars
Count Dooku In the opening of Star Wars: Episode III – Revenge of the Sith, set three years later, Dooku and Separatist commander General Grievous kidnap Supreme Chancellor Palpatine—Sidious' alter ego—as part of a plan orchestrated by Palpatine to lure Anakin to the dark side of the Force. Anakin and Obi-Wan board Grievous' ship and confront Dooku, who knocks Obi-Wan unconscious, leaving Anakin to face the Sith Lord alone. Anakin gives in to his hatred of Dooku and uses the dark side to overpower him, severing both of Dooku's hands and leaving him helpless. Palpatine then tells Anakin to execute Dooku on the spot; after initial hesitation, Anakin brutally decapitates Dooku. This act sets off a chain of events that leads to Anakin's eventual fall to the dark side and transformation into Darth Vader.
Star Wars: Episode II – Attack of the Clones Ten years after the Trade Federation's invasion of Naboo, the Galactic Republic is threatened by the Separatist movement organized by former Jedi Master Count Dooku. Senator Padmé Amidala comes to Coruscant to vote on a motion to create an army to assist the Jedi against this threat. Narrowly avoiding an assassination attempt upon arrival, she is placed under the protection of Jedi Knight Obi-Wan Kenobi and his apprentice, Anakin Skywalker. The two Jedi thwart a second attempt on her life and subdue the assassin, Zam Wesell, a shape-shifter who is soon killed by her bounty hunter client before she can reveal his identity. The Jedi Council assigns Obi-Wan to identify and capture the bounty hunter, while Anakin is assigned to escort Padmé back to Naboo, where the pair develop a romantic attraction towards each other.
