The answer is a glaringly obvious NO. He was created by Victor Surge on the Something Awful forums back in 2009 for a contest. He's not real, he never was real, he doesn't exist in any real life mythologies.
Victor Surge, whose real name is Eric Knudsen, was inspired by H.P Lovecraft, Stephan King, William S. Burroughs, Silent Hill and Resident Evil, Zack Parsons’s “That Insidious Beast”, the Steven King short story “The Mist”, the SA tale regarding “The Rake”, reports of so-called shadow people, Mothman, and the Mad Gasser of Mattoon.
He does not exist. He is not real, he won't come after you, he doesn't dwell in some forest, he's not from any real life mythology, nobody has been "haunted" by him, no one's seen him in real life, NOTHING. Period.
