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.

In the novel The Truce at Bakura, set one day after the battle of Endor, Luke and his friend Wedge Antilles recover a message droid from the titular planet, which was being invaded by the Ssi-Ruuk. Luke commands a task force, turning back the enemy army. He also meets Dev Sibwarra, a Force-sensitive human who had been captured by the Ssi-Ruuk, who is killed in the battle after turning against his captors. In the novel The Courtship of Princess Leia, set four years after the Battle of Endor, Luke travels to the planet Dathomir. There, he discovers a group of Force-sensitive witches called the Witches of Dathomir, banded into two separate groups: a collective of benign, matriarchal clans; the one he is in contact with being the Singing Mountain Clan, and the witches who have turned to the dark side, called the Nightsisters. Discovering a prophecy in which it was told a Jedi would change the way of life on the land, Luke eventually realizes truly what the Force is for the first time in his life. While there, he destroys most of the Nightsisters (including their powerful leader, Gethzirion, and the galaxy's most powerful remaining warlord, Warlord Zsinj). Thanks to the help of the prophecy and witches, Luke recovers old Jedi records left by Yoda about 400 years prior. He decides to start a new Jedi Academy, something he has been trying to do for six months before the start of the novel by finding old Jedi records and archives. In The Thrawn Trilogy, Luke meets former Emperor's Hand Mara Jade, who is bound by Palpatine's disembodied voice that repeatedly commands "You will kill Luke Skywalker". Mara Jade is working with her boss, a fringe-of-the-galaxy smuggler named Talon Karrde, who also plays a crucial role in this era. Although she was ready to fulfill that order to stop the voice, circumstances force her to keep him alive long enough to have him help escape a mutual danger. Despite her threats, Luke learns of Mara's curse and vows to free her from it. Meanwhile, the rest of the New Republic is fighting against Grand Admiral Thrawn, and thanks to Leia's help, he is eventually defeated, although Luke tried several times to get near him and his ally, Joruus C'baoth. Eventually, the desperate pair fights against Luke's clone, Luuke Skywalker, the apprentice of Joruus C'Baoth. During the fight, Mara Jade destroys the clone and, with Leia's help, destroys C'baoth. This entire time, C'baoth has been obsessed with "molding" Luke and Mara to serve him, perhaps due to the fact that the Spaarti cloning cylinders he was made from have a reputation of turning people insane later in life. Nonetheless, C'baoth is defeated along with Luuke, and Mara's sacrifice silences her curse and completes her reconciliation with the Jedi, whom she later joins. CANNOTANSWER
