Count Dooku

In Star Wars Episodes II and II, Count Dooku, also known as Darth Tyranus, is a Sith Lord and commander of the Trade Federation. He and his master, Darth Sidious, give orders to officers and commanders of the Trade Federation, including General Greivous. Dooku also holds a Sith apprentice of his own, named Asajj Ventress. Dooku is a challenging opponent in lightsaber wielding, and usually has the upper hand due to his interesting fighting techniques and many years of experience. However, he was killed in Star Wars Episode III: Revenge of the Sith by Anakin Skywalker, the apprentice of Obi-Wan Kenobi.

Count Dooku tends to flee from battle to save himself, but he is not as nearly as cowardly as Greivous. Dooku was once a Jedi himself, and he had a Jedi apprentice, Qui-Gon Jinn. Qui-Gon was the master of Obi-Wan Kenobi. Once Dooku turned to the dark side, he could not turn back and quickly gained power both in authority and knowledge of the dark side of the Force.
