The Devil (American Horror Story)

"I know everything. I'm the Devil."

- Sister Mary Eunice, claiming to be the Devil while under demonic possession.

Sister Mary Eunice (full name: Mary Eunice Mckee) is a main villain in the thriller/horror tv show ''American Horror Story: Asylum. ''She took over the asylum and made it look nicer and tried to appeal to all the patients living there.

She was portrayed by Lily Rabe played Nora Montgomery in the first season of American Horror Story.

Personality and Appearance
A small, slender woman with blonde hair, she has pretty, gentle features. The blue of her eyes are now prone to flash orange or red and her cupid's bow lips to turn up in a sinister sneer.

Prior to the exorcism and death of Jed Potter, Sr. Mary Eunice was insecure and fragile, both fearing and desiring the iron fist of Sr. Jude. She put much trust in Dr. Arden, despite questioning the nature of his activities. After being possessed, she becomes sly and manipulative. She is seen making sexual advances to Dr. Arden and murdering one of inmates. It is implied throughout the show that Sister Mary Eunice, in her possessed form, possesses some sort of telepathy, or insight into one's past and desires. The extent of this ability is unclear, however.

Biography
As a teenager, she attended a pool party wherein she was stigmatized by a classic skinny-dipping prank that left her physically and emotionally exposed.

One of her acts was adding a jukebox to make the patients happier. Despite the things she has done she was still feared and hated by the people in the asylum.

She was believed to have been possessed by the Devil and had some unique powers to protect herself. Later on, she was killed by a priest at the asylum named Monsignor by being thrown off the third floor and falling to her death as she hit the ground floor. When she was agreed to be cremated, Arden was upset because he was loyal to her and ended up killing himself in the fire so he could go to heaven or hell in their case with her.
