Slenderman research

Slenderman is the antagonist in the free video game Slender, with many defining characteristics and abilities. It was first mentioned in Something Awful Forum's 'Create Paranormal Images'. Slenderman appears as a very tall man wearing a black or grey suit, black or red tie and a white shirt and is known to be up to 15 feet tall. It has no eyes, mouth, nose and ears, basically no facial features and even has no hair. You could probably describe it as Lord Voldemort's long-lost, faceless, tentacled, businessman twin brother.

Slenderman doesn't generally appear until the player collects the first page. Once it's appeared, it can teleport at regular intervals between randomly selected locations on the map, within a maximum range of the player, so it's out of their view. After the player collects the sixth page, it teleports in their view.

Slenderman has many abilities. For one, it can have about eight tentacles protrude from its back and shoulders, which it can also turn its arms into. Slenderman may use these tentacles to either provoke fear into the player or as extra arms and legs. Slenderman's other many abilities include time travel, camouflage, fire, sickness, mutilation, selective visibility (which means it can see who it wants to see), impersonation and Slenderwalking (the ability to appear and disappear at will). It had also been known for Slenderman to have some form of mind control. It can brainwash the victim; give them Stockholm Syndrome; or it can have mind control over the victim; turn them into Proxies; or it can have complete control over the victim; turning them into its own puppets.

Slenderman's appearance provokes a wide range of responses; particularly that of fear. It's mostly because of its towering and imposing size over a fully grown adult, which in itself copies the known fear of adults being taller than children. It's faceless and bald head might also be a factor because the thought of a person or a sentient being of any kind without a face can terrify people.
