Attack of the Clones (2002)

Count Dooku is introduced as the main antagonist of Attack of the Clones, as a former Jedi Master who abandoned the Jedi Order after losing faith in the Republic the Jedi served. He is also the leader of the Confederacy of Independent Systems, a confederation of planetary systems rebelling against the Galactic Republic.^[4] Dooku believes that the Republic is corrupt, and that its politicians are more interested in maintaining the bureaucracy and enriching themselves than in properly representing their people.

Dooku recruits bounty hunter Jango Fett (Temuera Morrison) to assassinate Padmé Amidala (Natalie Portman) on Coruscant, but the attempt on her life is foiled by her assigned Jedi protectors.^[5] A fight with Obi-Wan Kenobi (Ewan McGregor) forces Fett to flee from Kamino to Geonosis, and the bounty hunter rendezvous with his benefactor. After capturing Obi-Wan on Geonosis, Dooku tells him that he is attempting to save the Republic, explaining that thousands of senators are under the influence of a Sith Lord named Darth Sidious. In an attempt to convince Obi-Wan to join him, Dooku reminds him of his late master, Qui-Gon Jinn, who was Dooku's apprentice, and claims that he also would not have served the Republic had he known that a Sith was in control. Padmé and Obi-Wan's Padawan Anakin Skywalker (Hayden Christensen) later travel to Geonosis to rescue Obi-Wan, but are also captured; all three are promptly sentenced to death.

A Jedi strike team eventually arrives on the planet to rescue the trio, and are soon joined by the Republic's new clone army, resulting in a large-scale battle between the Republic and Separatist forces. Dooku tries to flee, but Obi-Wan and Anakin follow him and engage him in a lightsaber duel. Dooku subdues Anakin with Force lightning and duels and wounds Obi-Wan with his lightsaber. When Anakin comes to Obi-Wan's defense, Dooku then duels him, culminating in him cutting off the young Padawan's arm. Dooku's former Jedi Master, Yoda (Frank Oz), then arrives and the two duel. Unable to match Yoda's prowess, Dooku distracts him by using the Force to dislodge a large pillar and send it falling toward Anakin and Obi-Wan. Whilst Yoda is distracted and saves the two injured Jedi; Dooku escapes the planet in his solar sailer. Dooku then arrives on Coruscant, bringing the Geonosian designs of the Death Star to Sidious and informs his master that their plan is working: "The war has begun."

Revenge of the Sith (2005)

In the opening of Revenge of the Sith, set three years later, Count Dooku and Separatist commander General Grievous (Matthew Wood) have kidnapped Supreme Chancellor Palpatine (Ian McDiarmid)—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, the Invisible Hand, and confront Dooku, who knocks Obi-Wan unconscious, leaving Anakin to face the Sith Lord alone. Anakin gives in to his anger to overpower him, severing both of Dooku's hands and leaving him helpless. Palpatine then orders Anakin to execute Dooku on the spot. After initial hesitation, Anakin decapitates Dooku. This act of cold-blooded murder sets off a chain of events that eventually leads to Anakin's fall to the dark side and transformation into Darth Vader; As Palpatine's new Sith apprentice, Vader helps his master all but exterminate the Jedi Order and overthrow the Republic, turning it into the Galactic Empire.

In a scrapped scene from the film, Palpatine and Dooku claim that the latter arranged for the Tusken Raiders to kidnap and kill Anakin's mother Shmi (Pernilla August), as seen in Attack of the Clones.^[6]

The Clone Wars (2008)

In the 2008 CGI film Star Wars: The Clone Wars, Count Dooku plots to bring Jabba the Hutt into the folds of the Confederacy by enlisting Jabba's uncle Ziro the Hutt to kidnap Jabba's son Rotta. After Ziro's agents deliver the Huttlet to the planet Teth, Dooku contacts Ziro again to arrange for his minion Asajj Ventress (voiced by Nika Futterman) to take custody of Rotta. When Jabba requests Jedi assistance to rescue his son, Dooku plans to frame the Jedi for the crime. Dooku duels Anakin (voiced by Matt Lanter) for the first time since their encounter in Attack of the Clones. The duel ends in a draw, and Anakin and his Padawan Ahsoka Tano (Ashley Eckstein) eventually foil Dooku's plan.

The Clone Wars (2008–2014)

In the 2008 animated series Star Wars: The Clone Wars, set between Attack of the Clones and Revenge of the Sith, Dooku is the political leader of the Separatists, and the main antagonist. In addition to sending Grievous and Ventress on missions to antagonize the Republic, he works with the terrorist group Death Watch to give the Republic a reason to send a military presence to Mandalore, which would play in his favor. The plan falls through when Duchess Satine Kryze (Anna Graves) of Mandalore urges the Galactic Senate to hold off a military force.

In the third season, Dooku is forced to eliminate his apprentice Ventress to prove his loyalty to Darth Sidious. Ventress survives, however, and works with Mother Talzin (Barbara Goodson) to kill Dooku by giving him Savage Opress (Clancy Brown) as a replacement apprentice. During a confrontation between Dooku and Ventress, Savage turns on both. In the fourth season, Dooku defeats Anakin in three separate lightsaber duels, and gets his revenge on Ventress by having General Grievous order the systematic genocide of the Nightsisters. In the fifth season, Dooku plays minor roles via hologram in guiding King Rash of Onderon and Grievous taking over Florrum.

In the sixth season, Dooku finds out the clone trooper Tup executed Order 66 prematurely and works behind the scenes to stop the Republic's investigation. He then manipulates the Banking Clan and its representative Rush Clovis (Robin Atkin Downes) into putting all their resources in the hands of the Sith, bringing war to the planet Scipio. Later, the Jedi find a lightsaber belonging to deceased Jedi Master Sifo-Dyas—whom Dooku murdered years earlier—and start an investigation. Sidious forces Dooku to clean up their trail. Dooku confronts Anakin and Obi-Wan on Oba Diah, revealing his alter-ego Darth Tyranus to the Jedi, and they realize that it was he who created the clone army. Some further investigation by Yoda prompts Dooku and Sidious to perform a Sith ritual in an unsuccessful attempt to break the Jedi Master; in a vision experienced by Yoda, Dooku fights Anakin, who swiftly defeats and executes him, in a manner very similar to his eventual demise.

Count Dooku does not directly appear in the seventh season. However, as the events of Revenge of the Sith are concurrent with the season's final arc, Ahsoka Tano is informed of his demise at Anakin's hands by Obi-Wan, who tells her that it is important to capture Maul, being the only way the Jedi can discover the true identity of Darth Sidious after Dooku's death.

Tales of the Jedi (2022)

A younger Count Dooku serves as one of the two protagonists of animated miniseries Tales of the Jedi, voiced once again by Corey Burton. He is the focus of the second, third, and fourth episodes, which depict his life as a Jedi, his increasing dissatisfaction with the corruption in the Jedi Order and the Senate, and his eventual fall to the Dark Side. The miniseries also focuses on Dooku's friendship with his padawan Qui-Gon Jinn, with original actor Liam Neeson returning to voice the character in the episode set concurrently to The Phantom Menace.

Dark Disciple (2015)

An unfinished sixth season arc of The Clone Wars was adapted into the 2015 novel Dark Disciple by Christie Golden. In the story, Dooku commands a genocidal attack on the planet Mahranee, leading the Jedi Council to send Master Quinlan Vos on a mission to assassinate Dooku. Vos partners with Dooku's former apprentice Asajj Ventress for the mission. The two confront Dooku on the planet Raxus Secundus, where Dooku was being awarded at a ceremony, but are no match for the Sith Lord, who captures Vos and forces Ventress to flee. Dooku takes Vos to Serenno, where he tortures him, eventually turning him to the dark side. Sometime later, the Jedi Council liberates Vos with the assistance of Ventress. However, upon deducing that he has turned to the dark side, the Council sends him to face Dooku again as a test of loyalty, with Obi-Wan Kenobi and Anakin Skywalker tailing him. Vos defeats Dooku, but spares his life and instead demands Dooku to lead him to Darth Sidious. Obi-Wan and Anakin arrest them and take them to Kenobi's Venator-class Star Destroyer. Vos and Dooku escape aboard Ventress' ship, killing two Jedi and many clone troopers in the process. They are shot down and crash-land on Christophsis, where they seek refuge in a Separatist tower, which is soon under attack by Jedi and Republic forces. Dooku attempts to kill Vos with Force lightning, but Ventress sacrifices her life and saves Vos. After killing Ventress, Dooku escapes the planet.^[7]

However, after he saves his homeworld of Serenno from invaders, he decides to remain to help his planet rebuild, leaving the Jedi Order and becoming Count Dooku of Serenno.^[8]

Thrawn: Alliances (2018)

In Thrawn: Alliances, Dooku is mentioned by Duke Solha and Padmé Amidala while they fight at Mokivj. Solha establishes that the Count had dispatched him and his siblings to Mokivj to produce cortosis B2 super battle droids for the Clone Wars.^[9]

Master & Apprentice (2019)

The novel Master & Apprentice by Claudia Gray recounts several adventures from Qui-Gon Jinn's apprenticeship under Dooku, as well as Dooku's obsession with Jedi prophecies and seeming use of Force lightning during a mission. The novel also reveals that Dooku had one other apprentice before Qui-Gon, Rael Averross.^[10]

Comic books

In the Star Wars: Republic series, set during the Clone Wars, Dooku trains multiple Dark Jedi apprentices, most of whom he uses as minions. His apprentices include Ventress, Tol Skorr and renegade Jedi Quinlan Vos. Vos initially intended to infiltrate the Separatists as a spy for the Jedi Council but instead nearly falls to the dark side.

Novels

In Jude Watson's Legacy of the Jedi, Dooku appears in Parts 1, 2, and 4, and is mentioned in Part 3. In Part 1, he is first tempted by the dark side of the Force as a child when his best friend and fellow Padawan Lorian Nod steals an ancient Sith Holocron from the Jedi Archives. When Nod is caught, Nod lies and says that the theft was Dooku's idea. However, Dooku manages to convince the Jedi Council of the truth, and Nod is then expelled from the Jedi Order. It is later implied that Dooku himself steals the Holocron because he is intrigued by the Sith's open embrace of power. In Part 2, set 13 years later, he is a Jedi Knight, and takes Qui-Gon Jinn as his Padawan apprentice. He encounters Nod while defending a Senator from space pirates, and defeats him in combat, almost executing him. However, Qui-Gon convinces him to spare Nod's life, and he and Dooku turn Nod over to the authorities. In Part 3, set 32 years later, Qui-Gon, now a Jedi Knight, remarks that he has not seen Dooku in years, noting that their relationship was never friendly. Finally in Part 4, set in the midst of the Clone Wars, Dooku, now a Sith, kills Nod after his former friend refuses to join the Separatists.

In Sean Stewart's Yoda: Dark Rendezvous, Dooku attempts to trap Yoda by offering to negotiate an end to the Clone Wars. Dooku attempts unsuccessfully to sway Yoda to his cause, while Yoda nearly convinces Dooku to return to the Jedi Order. When Anakin and Obi-Wan appear unexpectedly, Dooku believes that Yoda was trying to set him up to be captured, and renounces his former master once and for all. In the novel, it is also revealed that Dooku always resented his parents for "giving him away" to the Jedi Order.

In James Luceno's Labyrinth of Evil, Dooku engineers Grievous' transformation into a cyborg and trains him in lightsaber combat. He then schemes with Sidious to invade Coruscant in what he believes to be a plot to kill Obi-Wan and initiate Anakin into the Sith.

Matthew Stover's novelization of Revenge of the Sith expands upon Dooku's character; it portrays him as an evil man who sees others as mere objects to be used and discarded, and who despises the galaxy's non-human species and plans to exterminate and enslave them once in power. It also explains that Dooku believes that Palpatine's staged kidnapping is part of a plan to kill Obi-Wan and turn Anakin to the dark side. In this scenario, once the Republic becomes the Galactic Empire, Dooku and Palpatine will rule the galaxy together, while Anakin will command a "Sith Army" formed from the remains of the Jedi. The novelization depicts Dooku's death scene from his point of view. In his final moments, he realizes that Palpatine used him as a means to engineer the war and as a placeholder for Anakin, whom he intended to be his apprentice all along.^[11]

Clone Wars (2003–2005)

During the 2003 animated micro-series Star Wars: Clone Wars, Count Dooku leads the Separatists from behind the scenes, taking the dark assassin Asajj Ventress (voiced by Grey DeLisle) as his apprentice while training General Grievous in lightsaber combat.
