Emperor Palpatine
Throughout Star Wars episodes 1-6, Palpatine orchestrates a slow and patient takeover of the galaxy. First, he creates a need for war. Then, he splits up the galaxy and plays both sides. Convincing Jar Jar and the Senate to give him supreme power, he slaughters the Jedi while luring his powerful apprentice, Darth Vader, to his side. With the Death Star constructed and at his command, he rules the galaxy with an iron fist. Even at the end, it takes Luke’s pleas to convince Vader to throw Palpatine to his ultimate demise.
