Darth Vader/Anakin Skywalker (James Earl Jones/Hayden Christensen): The saga's big bad starts off as a brave Jedi Knight before Darth Sidious seduces him to the dark side of the Force. He then becomes a Sith Lord and gruesomely helps the Empire destroy the Jedi Order. Father to Luke and Leia.
The Emperor/Darth Sidious/Palpatine (Ian McDiarmid): This guy is the absolute worst. He leads a double life as a Naboo Senator in the Galactic Republic and also as a Sith Lord named Darth Sidious. He restores the Sith, turns Anakin to the dark side, eradicates the Jedi Order from within, and overthrows the Republic so he can lead as the Emperor of the Galactic Empire. Rude. As. Hell.
Jabba the Hut: A truly disgusting, slimy, oversize worm and big-time gangster in the criminal underworld.
