5. Slenderman (Slenderman)
Slenderman might be the most popular character I have in this list. He is a man without a face, that has grown into an icon in the last year, and finally got his own video game. Frankly, I wouldn't be surprised to see a full length Slenderman movie in theaters in the near future. Slenderman is one of the few characters on this list where just the sight of him is terrifying. As soon as you see him, you know you're screwed. As you collect pages and the music picks up, the fog grows thicker and you can feel Slenderman almost breathing on the back of your neck, even though his absence of a mouth makes it puzzling as to how you feel his breath. If he catches you, you're dead. You better watch out because is going to get you. It's only a matter of time.
