10 Best Star Wars: The Clone Wars Episodes
7. Nightsisters
When Darth Sidious believes Count Dooku's apprentice, Asajj Ventress, is growing too powerful, Dooku leaves her to die. Ventress survives, and, consumed with revenge, heads home to Dathomir, where she teams up with her old order, the Nightsisters, in order to kill Dooku.
Turning themselves invisible, Ventress and two Nightsisters battle Dooku by turning themselves invisible and blinding him. Though he survives their awesome lightsaber fight, an on-edge Dooku comes to the Nightsisters for a new apprentice, leading to the introduction of Savage Opress in the next episode.
Nightsisters introduces a new kind of magic to the Star Wars universe, one uninvolved with the force. The mystical world of the Nightsisters feels like it belongs in a Halloween special, with the potions and spells creating the creepiest environment in Star Wars.
Additionally, Nightsisters kicks off the rivalry between Ventress and Dooku, beginning with their epic invisible lightsaber fight and carrying on until Ventress's final appearance in The Wrong Jedi.
