Luke Skywalker is the main protagonist of the Star Wars films Star Wars Episode IV: A New Hope, Star Wars Episode V: The Empire Strikes Back and Star Wars Episode VI: Return of the Jedi. He is portrayed by Mark Hamill. Luke plays a major role in the original trilogy as he learns the ways of the Jedi and becomes an important figure in the Rebel Alliance, leading the struggle against the Galactic Empire. As the son of former Queen of Naboo and Republic Senator Padme Amidala and her husband, Anakin Skywalker — a fallen Jedi also known as the Sith Lord Darth Vader — Luke is heir to a family deeply powerful in the Force. He is also the fraternal twin brother of Princess Leia Organa of the planet Alderaan, foster daughter of Senator Bail Organa and a leader of the Rebellion who recruited her brother into the cause. In the Expanded Universe, he becomes a powerful Jedi Master and eventually the Grand Master of the New Jedi Order, as well as the father of Ben Skywalker, maternal uncle of Jacen Solo and ancestor of Cade Skywalker.
