who defeated obi-wan kenobi in a lightsaber duel
Obi-Wan Kenobi In the spaceport city Mos Eisley, Obi-Wan uses the Force to trick Imperial troops into letting them through a military checkpoint. They enter a local cantina and make a deal with two smugglers, Han Solo and Chewbacca, to fly them to Alderaan aboard their ship, the Millennium Falcon. During the journey, Obi-Wan begins instructing Luke in lightsaber combat. He suddenly becomes weak and tells Luke of "a great disturbance in the Force". Emerging from hyperspace, the party finds that Alderaan has been destroyed by the Empire, and the Falcon is attacked by an Imperial TIE Fighter. The trio chase the TIE fighter to the Death Star, and subsequently get caught in the space station's tractor beam. On board the Death Star, Obi-Wan shuts down the tractor beam, but Darth Vader confronts him and they engage in a lightsaber duel. Obi-Wan uses the duel to distract Vader as Luke, Leia, Han and Chewbacca escape to the Falcon. Although Vader strikes Obi-Wan down, his body mysteriously vanishes the moment he dies. At the climax of the film during the Rebel attack on the Death Star, Obi-Wan speaks to Luke through the Force to help him destroy the Imperial station.

Star Wars: Episode III – Revenge of the Sith Palpatine appoints Anakin to the Jedi Council as his representative, but the Council declines to grant Anakin the rank of Jedi Master and orders him to spy on Palpatine, causing Anakin's faith in the Jedi to diminish significantly. Palpatine tantalizes Anakin with secret knowledge of the dark side of the Force, including the power to save his loved ones from dying. Meanwhile, Obi-Wan travels to the planet Utapau, where he kills Grievous, and Yoda travels to Kashyyyk to defend the planet from invasion. Tempting Anakin, Palpatine eventually reveals that he is the Sith Lord Darth Sidious, saying that only he has the knowledge to save Padmé from dying. Anakin reports Palpatine's treachery to Mace Windu, who confronts and subdues the Sith Lord, severely disfiguring him in the process. Fearing that he will lose Padmé, Anakin intervenes on Palpatine's behalf and severs Windu's hand, allowing Palpatine to throw him out of a window to his death. Anakin pledges himself to Palpatine, who dubs him Darth Vader. Palpatine issues an order for the clone troopers to kill their Jedi commanders and dispatches Vader along with a legion of clones to kill everyone in the Jedi Temple. Vader then massacres the remaining Separatist leaders hiding on the volcanic planet Mustafar, while Palpatine addresses the Galactic Senate, transforming the Republic into the Galactic Empire and declaring himself Emperor. Having survived the chaos, Obi-Wan and Yoda return to Coruscant and learn of Anakin's treachery.
