4. The Three Sisters
The Three Sisters were a trio of seductive vampires who served the infamous Count Dracula. They joined their master when he travelled to Sunnydale in search of the Slayer, Buffy Summers. When Buffy was taken to the castle by Xander Harris, who was enthralled into Dracula's servitude at the time, one of the sisters greeted them and took them inside. A few hours later, Rupert Giles and Riley Finn stormed Dracula's castle in their attempt to save Buffy from Dracula, but Giles fell inside a pit where he was approached by the Sisters. The trio then seduced him in order to keep him away from their master and Giles, who had previously thought that they were nothing more than a myth, was quite taken by them. They prepared to feed on him until they were driven off by Riley when he brandished a cross and they left Sunnydale along with Dracula when Buffy defeated him.
