Slenderman

About him
The Slender Man (also known as Slenderman) is a supernatural creature with nebulously defined characteristics and abilities. Slenderman was first mentioned in Something Awful Forum's "Create Paranormal Images". Slender Man generally appears (in modern times) as a tall man in a black or grey suit, red or black tie, and white shirt, with no eyes, mouth, or clearly defined facial features. It has no hair, and generally has normal-looking bare hands, albeit with fingers longer and bonier than a typical human. Slenderman is typically depicted in imagery and literature as between 6 and 15 feet tall, depending on the situation, and in the video as around 6-7 feet tall. Because of its inexact nature and differences between series, no one has yet determined what it is.

He is the leader of all Creepypasta people. He possesses the powers of transportation and his 8 well-known pages. His biggest enemy in the Creepypasta is Jeff the Killer, while in the game is Pigsaw. Slender Man is known for his scaring act of children and adults, kidnapping them and killing them. He also has 4 or 6 tentacles on his back.
