[🌲 ] Slenderman

cruel, sadistic, manipulative, predatory, misanthropic demon

Slender Man's general appearance consists of a tall figure standing from 6 to 14 feet tall wearing a black suit, white shirt, a black or red tie, black trousers, and black shoes. Slender Man's skin is pale white, and he has no facial features of any kind, although some depict him as having somewhat empty visible eye sockets, nose, and mouth. Slender Man is also iconic for having long black tentacles (also seen as extra-long hands) which he usually uses to snag in victims. However, it is possible that this is not his real form, and that he is actually an eldritch being whose true form cannot be comprehended.

Many stories seem to indicate that The Slender Man can control a person's mind, which became the basis for the Proxies in the video ARG, a trend that later spread to Slenderblogs. The Slender Man also originally had stronger connections to children, and many of the original stories revolved around disappearing children or featured Slender Man sightings in photos with children. This was often attributed to the innocence and morbid curiosity of children, which could lead them down the path of discovering the creature.

As more stories came forth, however, the use of tentacles and tentacle-like appendages became less common, and the invisibility was limited or eliminated depending on the storyteller. (On the other hand, some stories took the invisibility even further and claimed it was entirely invisible without the use of electronic devices.)

EMH, TT, ML, and DH all contain some sort of video and/or audio distortion, indicating that The Slender Man has an effect on modern digital instruments. This does not appear in any of the original accounts, but these also mainly make use of photographs and lower-tech video. EMH has suggested that this distortion is the effect of Sigma Radiation, radiation said to be given off by Slender Man and the Rake. Sigma Radiation is also contagious, as it entered Evan's blood-stream when his arm was brutally maimed by The Rake.

EMH and ML also describe the phenomenon known as "Slender Walking." Slender Walking is a term created to describe Slender Man's apparent teleportation and space-time warping/teleportation between locations. These abilities were seen in early Slender Man accounts and are one of the most recognizable elements of the mythos. Slender Man’s ability to appear – seemingly from nowhere – in a place where he wasn’t mere seconds before is one of his most terrifying traits and EMH mentions the effect of this on a person's mental health.

Certain contemporary views see his movement as either extremely limited or impaired as if he is incapable of moving his body properly.
