The Slender Man was brought up at the Something Awful Forums in a thread entitled "Create Paranormal Images." He is described as wearing a black suit strikingly similar to the visage of the notorious Men In Black, and as the name suggests, appears very thin and able to stretch his limbs and torso to inhuman lengths in order to induce fear and ensnare his prey. Once his arms are outstretched, his victims are put into something of a hypnotized state, where they are utterly helpless to stop themselves from walking into them. He is also able to create tendrils from his fingers and back that he uses to walk on in a similar fashion to Doc Ock, the Spider-Man villain in the Marvel Universe. The superhuman stretching ability could also be seen as a similiarty between himself and Mr. Fantastic of the Fantastic Four. Whether he absorbs, kills, or mearly takes his victims to an undiclosed location or dimension is also unknown as there are never any bodies or evidence left behind in his wake to deduce a definite conclusion.
Not much is known, as no specific information has been found about origins, but his objective and habitat are made very clear. He has the need to kidnap children, and is seen right before the disappearance of a child or multiple children. He seems to prefer fog enshrouded streets and wooded areas as a way to conceal himself from being noticed. It should also be noted that children have been able to see him when no other adults in the vicinity could. Children also have dreams or nightmares concerning The Slender Man before their disappearance. Confiding these stories to their parents are met with the usual parental admonition: overactive imaginations.
Even though The Slender Man is fairly new in the media, people have already claimed sightings. He appears to the unwitting mostly at night, and most always peering out of wooded areas or near rivers. He has also been reported to peek inside left open windows and to walk out in front of lone motorists on long uninhabited roads. The Slender Man or men, have appeared everywhere from Japan, Norway, and America to name a growing few.
"we didn't want to go, we didn't want to kill them, but its persistent silence and outstretched arms horrified and comforted us at the same time..."
1983, photographer unknown, presumed dead.
One of two recovered photographs from the Stirling City Library blaze. Notable for being taken the day which fourteen children vanished and for what is referred to as "The Slender Man". Deformities cited as film defects by officials. Fire at library occurred one week later. Actual photograph confiscated as evidence.
1986, photographer: Mary Thomas, missing since June 13th, 1986.
A sighting of Slender Man was possibly inspiration for the famous Johanne Goethe poem and Schubert song "Der Erlkonig" (translated- "Night King" or "Boogeyman). The poem and ballad are about a father and his son riding horseback to their home, the son fearfully talks of visions of the "Erl Konig" while the father tries to comfort and dismiss the visions. The Erl Konig and Slender Man have surprising similarities in their appearance and actions when looking at a translation.
"My son, wherefore seek'st thou thy face thus to hide?" "Look, father, the Erl King is close by our side! Dost see not the Erl King, with crown and with train?" "My son, 'tis the mist rising over the plain."
