The Slender Man was created on the Something Awful forums in a thread to create paranormal images. Since then, more and more pictures have come around of him, making him an internet phenomenon. A series of Youtube videos were and are being uploaded on Marble Hornet's channel, all of them a story about people who are being followed by the Slender Man. Slender Man is depicted as being unnaturally tall, with very long limbs or tentacles that he can adjust the length of. He has the need to kidnap children, and his limbs are said to hypnotize them, making them unable to stop themselves from walking into them. When they are captured, it is unknown what happens, although it is suggested Slender Man takes them to an alternate universe. Sometimes a piece of cloth is left behind when children are taken. Slender Man blends in with trees, and usually hides in plain sight. The more you know about him, the closer he gets.
