Dark Lords of the Sith

Darth Vader (born Anakin Skywalker) appearing as an antagonist in the original trilogy Star Wars.
Originally a Jedi prophesied to bring balance to the Force, he falls to the dark side of the Force and serves the evil Galactic Empire at the right hand of his Sithmaster, Palpatine (also known as Darth Sidious).
He is also the father of Luke Skywalker and Princess Leia Organa. Anakin had been Obi-Wan’s brilliant student, but hag gone to the dark side with the persuasion of Palpatine.
Anakin battled Kenobi on the site of a volcano and was badly wounded, but was then reborn as Vader. Meanwhile, Kenobi hid Luke on Tatooine while the Galactic Republic became the tyrannical Galactic Empire and Vader systematically hunted down and killed the Jedi.
He kills the Emperor by throwing his former master down the Death Star’s reactor shaft. In the process, however, he is mortally wounded by the Emperor’s lightning. With his dying breath, he tells his son that there was good left in him after all.
