Luke Skywalker is a fictional character and the main protagonist of the original film trilogy of the Star Wars franchise created by George Lucas. The character, portrayed by Mark Hamill, is an important figure in the Rebel Alliance's struggle against the Galactic Empire. He is the twin brother of Rebellion leader Princess Leia Organa of Alderaan, a friend and brother-in-law of smuggler Han Solo, an apprentice to Jedi Masters Obi-Wan "Ben" Kenobi and Yoda, the son of fallen Jedi Anakin Skywalker (Darth Vader) and Queen of Naboo/Republic Senator Padme Amidala and maternal uncle of Kylo Ren/Ben Solo. The now non-canon Star Wars expanded universe depicts him as a powerful Jedi Master, husband of Mara Jade, the father of Ben Skywalker and maternal uncle of Jaina, Jacen and Anakin Solo.

Introduced in the 1977 film Star Wars (later dubbed Episode IV - A New Hope), the character represents the hero archetype of "the young man, called to adventure, the hero going out facing the trials and ordeals, and coming back after his victory with a boon for the community".  Luke Skywalker lives on a moisture farm on Tatooine with his Uncle Owen and Aunt Beru. Luke takes his first steps toward his destiny when he purchases the droids C-3PO and R2-D2. While examining R2-D2, he sees a message from Leia. When R2-D2 goes missing, Luke goes out to search for the droid, but is knocked out by Tusken Raiders in the process. He then encounters Obi-Wan Kenobi, an old hermit. Luke and Obi-Wan seek shelter, and R2-D2 plays the full message for Obi-Wan from Leia, beseeching him to help her defeat the Galactic Empire. Obi-Wan says that he and Luke's father were once Jedi Knights, and that his father was murdered by a traitorous Jedi named Darth Vader. Obi-Wan presents Luke with his father's lightsaber and offers to take him to Alderaan and train him in the ways of the Force, but Luke rejects his offer.  Luke changes his mind when he returns home to find out that Imperial stormtroopers have killed his aunt and uncle. He and Obi-Wan then travel to Mos Eisley, where they meet smugglers Han Solo and Chewbacca at the Cantina. They team up and travel on the Millennium Falcon to Alderaan, only to find out that it has been destroyed by the Death Star. They board the Death Star and rescue Princess Leia. Obi-Wan deactivates the tractor beam, and he later sacrifices his life in a duel with Vader, so that Luke and his friends can board the Falcon and escape.  During the Battle of Yavin, Luke joins the Rebel Alliance in attacking the Death Star. In the trench leading to the Death Star's exhaust port, Luke hears Obi-Wan's voice, telling him to "trust his feelings"; he takes Obi-Wan's advice and switches off his X-wing's missile guidance system, instead using the Force to guide the missiles and destroy the Death Star.
