I’ll take Slender_Man

Death (Final destination franchise)

@Overlord 427 I do not think you can pick him, for he has never been in a horror movie/tv show, my friend.

@AshAndrewFlame I think yours will not count as well, for I know there was a documentary or something created on it, but he is not showcased in a horror movie/TV Show. Correct me if I am wrong.

Chuck AKA GOD:Supernatural

There is a documentary called Beware the slender man that came out in 2016 but there’s also a movie that came out in 2018
