Slender Man

The Slender Man is one of the most famous Creepypastas of all time, being a featureless, sickly pale, and lanky humanoid who stalks and kidnaps adults and children alike, coldly turning them into his mindless minions.

Created by Victor Surge in 2008, the Slender Man was popularized and immortalized by the 2012 indie horror game Slender.
