Slender Man

The Slender Man is a mysterious being with variously described qualities. The legend originated on the Something Awful Forum's "Create Paranormal Images" contest. While not much is agreed upon about the Slender Man, it is generally accepted that it is a malevolent entity. The legend became incredibly popular with the release of the indie game, Slender.

Description
The Slender Man appears as a tall, slender human, hence the name. It wears a black or grey formal suit, a white shirt, and a black or red tie. The face lacks any distinct features or hair. The Slender Man is also reported to be able to stretch its limbs to incredible lengths, similar to Mr. Fantastic's ability. Some also say that it can sprout tentacles from its back at will to help ensnare its victims. The Slender Man also can teleport and is never seen to walk, hinting towards its existence as a spirit.

The Slender Man generally inhabits forests or other uninhabited areas, only straying into densely populated suburbs on occasion, usually to stalk its victims. It may mentally torture its victims for years before actually striking. While it is unclear what exactly the Slender Man does with its victims, some claim that it consumes them.

In the Parodies
The Slender Man appeared in the bunker when Himmler mails the eight pages from Slender. It attacks several people throughout the bunker, even Hitler himself, abducting them to an unclear fate...

Benad361 and HitchcockJohn are planning a joint parody based around the legend of Slender Man.
