The ruler of the Sith Empire, The Emperor is as powerful as he is mysterious, and serves as the primary antagonist of the movie. Having seized the throne of the Sith Empire after the it was massacred in the Great Hyperspace War, The Emperor then proceeded to rule the Sith with an iron fist for over 1000 years, operating from the shadows and consolidating his power to eventually rise up against the Republic. Rarely seen but ever-present on the lips of the Sith Lords who serve under him, The Emperor terrifies both his allies and enemies alike, as he has a complete disregard for any and all life in the galaxy. His patience borders on paranoia: he has spent centuries amassing his strength, and in doing so he developed a crushing, all-consuming fear of death. Few have had a personal audience with The Emperor and lived to tell the tale, as he is liable to kill any subordinate who displeases him, slaying them with a wave of his hand.

The Emperor speaks very slowly and has a strong air of menace to his voice, which is a low but smooth rumble.
