The most beast no faces CreepyPasta there is. Tall as fuck, and with arms and tenticles that can tear you to shreds he is quite a treat. He makes electronic devises go crazy when he is close to them. And the only thing that sucks is that his weakness is 8 pieces of paper

Standing in the woods, watching kids and chasing them through the forest , capturing them; raping them, then stealing their face. THEN YOU ASSUME THEIR IDENTITY AND LIVE THEIR LIFE, WHILE CLAIMING THE FACES OF EACH OF THEIR LOVED ONES!
