These were the original two images of the Slender Man posted to the somethingawful forums and are considered the origin of the character. The poster, known only as “Victor Surge,” accompanied them with the following two quotes:
(To the top image): 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.
(To the bottom image): “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.
The post was followed with a post from “slidebite”: “You just know a couple of the good ones are going to eventually make it to paranormal websites and be used as genuine.”
A perfect example of the most common kind of Slender Man image, in which the Slender Man can only be seen from a great distance and even then only barely be made out.
No videos exist with the Slender Man depicted with this kind of clarity, and this is only one of a handful of images that do so and present themselves as “authentic.” Clearly, this image embraces the Slender Man’s “spiderlike” aspects centered on the slender “Men in Black” style suit.
This is the hallmark Slender Man image featured front and center on many of the sites devoted to the legend. It focuses on the fact that the Slender Man has the ability to stretch his limbs to unreasonable lengths.
The Slender Man of the Marble Hornets Youtube series. He is generally depicted as more human-like in that series than in others, this likely being a budgetary necessity as he is often depicted as walking and it was undoubtedly easier to hire an actor to be filmed from a distance rather than use a computer to generate something monstrous.
The “Operator” symbol, also from the Marble Hornets series. This aspect of the series is a unique addition to the Slender Man mythos by connecting the Slender Man to a cult somehow using the symbol as a way to communicate with the Slender Man.
One of the many artists’ renderings of the Slender Man that make no claim of authenticity, implied or otherwise. Here the Slender Man is depicted with a blank face (some images have the face dominated by a gaping mouth) likely because his face is described as being so terrifying that it cannot be put into words, and therefore a blank face is used.
One of several Slender Man documentaries produced. This is the most common style regarding Slender Man produced on the internet, as Slender Man is creepiest when presented as “found footage,” garbled audio and grainy images.
The only attempt thus far to make a feature length Slender Man movie. The movie is terrible thanks to poor acting and a very poor script, but is enough to make you wish for the concept to be given an authentic Hollywood treatment.
The first documentary produced regarding the Slender Man, notable for its lack of narration.
“Slender Suits,” the most well-produced as well as most recent documentary on the subject of the Slender Man.
The introduction and first entry on the Marble Hornets channel, regarded as the most successful example of an exploration into the Slender Man mythos. The series is presented initially as a search through old footage from a long-lost college friend, whom we quickly learn was being stalked by the Slender Man. It was the way I was first introduced to the Slender Man, and watching the first few episodes are enough to make you believe that the Slender Man might in fact be real. However, the man behind the series has produced over fifty entries in the series and thanks to substandard acting and writing it eventually becomes obviously fake. The effort is admirable though, and remains creepy for quite a while.
The first episode of totheark’s Youtube posts. Totheark is the sister channel to Marble Hornets, and is in fact meant to be the Youtube channel of the Slender Man himself. The posts are garbled and meaningless, with a few clues to Marble Hornets within them.
The twelvetribes story is virtually identical to Marble Hornets and was made after it. There are several other derivative channels that tell very similar stories to Marble Hornets.
