As the Clone War nears its end, a huge spaceship battle rages over Coruscant. General Grievous, the evil head of the Separatist droid army has captured the Republic leader, Chancellor Palpatine, and is holding him hostage aboard his star ship. Anakin and Obi-Wan Kenobi infiltrate the vessel and confront Sith Lord Darth Tyranus (Count Dooku). The Jedi fight Tyranus and Obi-Wan is knocked unconscious. Anakin defeats Tyranus, slicing off his hands and literally bringing him to his knees. Urged on by the chancellor, Anakin beheads Tyranus with his lightsaber. But Anakin is deeply disturbed and appalled by his actions—a Jedi would never commit such an unnecessary and heinous act. Palpatine is freed and Obi-Wan regains consciousness, but the trio is quickly captured and taken to General Grievous on the bridge. The Jedi destroy his Magna Guards, but Grievous escapes. As Grievous’ heavily damaged spaceship crashes towards the planet, Anakin takes control and lands it safely. Yoda sends Obi-Wan to the Utapau system to find and capture General Grievous and the other separatists. At Darth Sidious’ command, Grievous is relocating the separatist leaders to the molten planet Mustafa.
During a brief reunion, Padme tells Anakin she’s pregnant. Although he says it’s wonderful, he’s deeply concerned about their situation and begins having nightmares that Padme dies in childbirth. Chancellor Palpatine has expanded his powers over the senate and extended his stay in office long after his term was to expire. At Palpatine’s insistence, Anakin is appointed to the Jedi Council as his representative. Anakin is angry when he is denied the rank of Jedi Master. Suspicious of the chancellor’s motives, the council agrees to Anakin’s appointment only because they want him to report on Chancellor Palpatine actions. The chancellor increases his influence over Anakin by telling him about a Sith Lord who had the power to prevent death. He tells Anakin that together they can learn this power and save Padme. Palpatine says he knows the Jedi Council wants Anakin to spy on him, and Anakin confirms they distrust him.
