He's one of the most talked-about online phenomena, and for good reason,Slender Man is one scary dude, a dread-inspiring boogeyman for the digital age. He has at least half a dozen nicknames, including "Slendy," "The Tall Man," Mr. Slim," "Daddy Long legs," and "The Operator." The chatter started in 2009, when mysterious photos started going around showing a creepy, ghostly figure clothed in black stalking children in schoolyards and playgrounds. It was rumored that the people who took the photographs were never seen or heard from again. Their disappearances were blamed on Slender Man, as were those of many missing children, and even some adults, all over the world.
You'll know Slender Man when you see him. He's gaunt, stands eight to ten feet tall, and instead of arms and hands has multiple, writhing tentacles that come to razor-sharp points (the better to skewer his victims!). Creepiest of all, they say Slender Man doesn't have a face. In photographs and drawings his face is rendered either completely featureless and blank-a fuzzy, amorphous blob or wrapped in gauze like a mummy.
No one knows how or why Slender Man chooses his victims, but once chosen, they will be stalked, taken to a isolated location (most often in the woods), and killed. Some say he befriends those he intends to kill, luring them to their deaths with offers of kindness and sympathy. Others say he stalks his victims invisibly, and the only palpable sign you have been targeted is a phenomenon called "Slender Sickness," the symptoms of which include nausea, nose bleeds, nightmares, hallucinations, and "massive paranoia." If you begin to experience any of these for no apparent reason, watch out, Slender Sickness is the prelude to your disappearance and grisly demise.
