10Dr. Oliver Thredson
Zachary Quinto portrays Dr. Oliver Thredson, a sick and twisted lady killer called "Bloody Face" who masquerades as a compassionate, court-appointed psychiatrist in AHS: Asylum. While he might not have had supernatural powers, like some of the characters on this list, he certainly had the power to manipulative and deceive
whoever had the misfortunate of meeting him.
Dr. Thredson even managed to deceive the viewers, most of whom came to see him as a friend and ally of Lana Winters, a journalist who finds herself trapped in a mental hospital. American Horror Story sure loves its unexpected twists and turns!
