Slender Man (a.k.a Slenderman) is a mythical creature often depicted as a tall, thin figure wearing a black suit and a blank face. According to the legend, he can stretch or shorten his arms at will and has tentacle-like appendages protruding from his back. Depending on the interpretations of the myth, the creature may cause memory loss, insomnia, paranoia, coughing fits, photograph/video distortions and can teleport at will. The urban legend has inspired fan arts, fictional creepypastas and a mockumentary series in the style of the 1999 indie horror film Blair Witch Project. As the character has grown in popularity, he's gained a number of other nicknames including The Operator, Mr. Slim, The Administrator, Mr. Thin, The Tall Man, The Thin Man and Slendy.
