I think Slendy is for kids, he is a fairy-tale legend. Zombies have become a cult, they are two levels above Slenderman. Someone mentioned hallucinations before :) well maybe that's not bad idea. Anyways, creating a new original creature, even inspired by Slenderman's powers would be better than actually putting in the actual Slenderman. I used to work with a guy who was writing horror stories for one of my blogs, but when I asked him to do something for this slender man page, he quit. this is what he wrote me "I just cannot bring myself to write another Slenderman article. I want to stalk and kill Slenderman myself. I'm sorry" Slenderman is a bad luck. I would stay away.
