Emperor Palpatine

Emperor Palpatine (or Darth Sidious) is the Sith Master of Darth Maul, Darth Tyrannus/Count Dooku, and Darth Vader. He was elected Chancellor in the Republic and was granted emergency powers in the Clone Wars in disguise, with no one truly knowing that he was Darth Sidious. Ever since Anakan Skywalker was taken in by Qui Gon Jinn, he has attempted to turn him to the dark side. He also orchestrated the fall of the jedi, by using the Republic's army: the Clones, by executing Order 66. He succeeded in putting Anakin on a path to the dark side, and turning him into Darth Vader. He then turned the Republic into the Galactic Empire and appointed himself as ruler of the galaxy. In the Original Trilogy, he attempts to get Anikan's son, Luke on a path to the dark side by making him fight his father. Seeing that Luke refuses to kill his father, the Emperor tries to kill Luke with his force lightning. Darth Vader then saves his son by throwing his master, the Emperor down the reactor core of the second Death Star, killing him.
