10 Terrifying Supernatural Monsters That Kept You Up At Night
9. Bloody Mary
Perhaps one of the most distinguishable horror-based episodes of Supernatural, Bloody Mary is an ode to horror classics such as The Ring and The Grudge. Focusing on a game of Bloody Mary that unleashes a ghost that only appears in mirrors remains of the creepiest episodes of the show to date.
The fifth episode of the first season sees the Winchester Brothers travel to Ohio where a group of teenagers have unleashed Bloody Mary. Again, playing on folklore and common cultural myths, the simplicity of the Bloody Mary design is what makes her stand out.
Simply being portrayed as a distressed dark-haired girl with a sinister, deathly look makes this one of the most understated yet creepy villains that the show has ever seen.
