Zachery Kralik

Zachery was a particular nasty vampire. Totally insane, he was sent to an asylum for torturing women. On Buffy's 18th birthday she had to pass a test, fighting without her slayer powers. The Watcher's Council chose Zachery. But they really didn't know who they were dealing with. Zachery broke out of his box which he was kept in, and headed towards Joyce, and kidnapped her. Buffy set out to find Zachery and her mother, and bring her back alive. She was harmless without her slayer powers, but when Zachery was in need of his pills, Buffy gave him Holy water, and he burned from inside out.

Sunday

Sunday had her own group of vampires who fed off innocent freshmen on campus. After she either fed off them or made them into a vampire, she stole the person's things from Sunnydale College, and left a note saying how the person couldn't cope. With the help of her vampire buddies. Buffy's first encounter with Sunday wasn't good, Sunday almost broke her arm. But after a pep talk from Xander Buffy went off and killed Sunday, in her lair.
