Star Wars: 10 Things You Didn't Know About Count Dooku
3. He's Had Many Apprentices
Speaking of Dooku's history of apprentices over the years, Assajj Ventress isn't the only savage presence to have taken up a spot under the Count's learning tree.
During his time under the tutelage of Darth Sidious, Dooku trained and guided three notably impressionable souls in the ways of both the Force and lightsaber mastery. On top of the deadly assassin Ventress, Savage Opress - Maul's brother - and Quinlan Vos - Ventress' one-time lover - both trained under Dooku at one point or another.
Dooku didn't give a toss about any long-standing Rule of Two, clearly.
He also had a hand in teaching General Grievous how to duel with a laser sword before the cyborg Separatist force was bested by Obi-Wan Kenobi in Revenge of the Sith. Of course, when operating as a Jedi Master, Dooku also trained Kenobi's former Master Qui-Gon Jinn and Rael Averross, along with a number of other Force sensitive folk in the Legends lore in the wake of his defection.
Simply put, Dooku's teachings could very much be felt across the galaxy.
