Slenderman is a mysterious creature, possibly a demon or shade. He always appears as a tall, white-skinned male with no face. He wears a tuxedo, and pitch-black tentacles grow out of his back. He appears in some old photographs at playgrounds, schools, etc. No recent photos exist of him, which means he is either dead or has become more stealthy. The people who took the photos report not seeing him, and only noticing him after taking the photo. He has the power to install fear in a person, tho the point of giving them a heart attack and leaving a markless death.
