Slender Man

The Slender Man (also called Slenderman, Slender, or Slendy) is a fictional supernatural character that originated as a creepypasta Internet meme created by Something Awful forum user Eric Knudsen (also known as "Victor Surge") in 2009. He is depicted as a thin, unnaturally tall humanoid with a featureless white head and face, wearing a black suit.

Stories of the Slender Man commonly feature his stalking, abducting, or traumatizing people, particularly children. The Slender Man has become a pop culture icon, although he is not confined to a single narrative but appears in many disparate works of fiction, typically composed online.
