Olivia Burtis

Olivia Burtis was the true main villainess from Satan's School for Girls, the 2000 remake of the 1973 film of the same title. She was the dean of the Fallbridge College for Girls, where Beth Hammersmith attended under the name Karen Oxford to find out the truth about her sister's death. In the film's climax, it is revealed that Olivia is the leader of a satanic cult of witches known as "The Five," which consisted of students at the college. In another revelation, the evil Olivia stated that she was involved in killing Beth's parents and sister, with the plan to coerce Beth to join her cult. After Beth took down the students, Olivia faced Beth herself, all the while arrogantly stating that she wasn't powerful enough. However, Beth's power from killing The Five ended up being strong enough to kill Olivia, as a bolt of lightning crashed through a window and destroyed her.

Olivia Burtis was played by Kate Jackson. Jackson appeared as Roberta Lockhart in the original 1973 film.
