Count Dooku

Count Dooku, also known as Darth Tyranus, was a former Jedi Master who turned to the dark side and became a powerful Sith Lord under Darth Sidious. Once a respected and noble figure within the Jedi Order, Dooku grew disillusioned with the Republic’s corruption and the Jedi’s complacency, leading him to abandon the Order. As leader of the Separatist movement during the Clone Wars, he played a central role in orchestrating the conflict that ultimately enabled Sidious to rise to power. Charismatic, intelligent, and a master duelist, Dooku trained Asajj Ventress and General Grievous in the dark arts, but was ultimately betrayed and killed by Anakin Skywalker—his death marking a key step in Anakin’s fall to the dark side.
