Slenderman

The Slender Man (also spelled Slenderman) 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 head and face, wearing a black suit.

Stories of the Slender Man commonly feature him stalking, abducting or traumatizing people, particularly children. The Slender Man is not confined to a single narrative but appears in many disparate works of fiction, typically composed online. Fiction relating to the Slender Man encompasses many media, including literature, art and video series such as Marble Hornets (2009–2014), wherein he is known as The Operator. The character has appeared in the video game Slender: The Eight Pages (2012) and its successor Slender: The Arrival (2013), as well as inspiring the Enderman in Minecraft. He has also appeared in a 2015 film adaptation of Marble Hornets, where he was portrayed by Doug Jones, and an eponymous 2018 film, where he was portrayed by Javier Botet.

Beginning in 2014, a moral panic occurred over the Slender Man after readers of his fiction were connected to several violent acts, particularly a near-fatal stabbing of a 12-year-old girl in Waukesha, Wisconsin. The stabbing inspired the documentary Beware the Slenderman, which was released in 2016.
