Count Dooku

Count Dooku is an effective troller who works for Darth Sidious. He is a master swordsman and he looks a bit like Saruman. This is because they are actually brothers, which explains why they are so powerful.

He also hates Anakin Skywalker, aka Darth Vader. This is because he has a hunch his master will want to replace him soon, so he makes his own Darth name: Darth Tyranus.
