Slender Man
Early stories featured him targeting children or young adults. Some featured young adults driven insane or to act on his behalf, while others did not, and others claim that investigating the Slender Man will draw his attention. The web series "Marble Hornets" established the idea of proxies (humans who fall under the Slender Man's influence) though initially they were simply violently insane, rather than puppets of the Slender Man. "Marble Hornets" also introduced the idea that the Slender Man could interfere with video and audio recordings, as well as the "Slender Man symbol", ⦻, which became a common trope of Slender fiction. Graphic violence and body horror are uncommon in the Slender Man mythos, with many narratives choosing to leave the fate of his victims obscure. Shira Chess notes that "It is important to note that few of the retellings identify exactly what kind of monster the Slender Man might be, and what his specific intentions are- these points all remain mysteriously and usefully vague."
