Who is/are this/these?

Can you name all of these Horror Icons and Legends, Supernatural Beings and Strange Creatures from Movies, Series, Games, Books, Comics, Mangas, Short Stories, Poems, Artists, Creators, Musicals, Videos, Creepypastas, Podcasts, Songs, Real Life Sightings and Real Life Legends? You need to write their names, not the franchise like "Darth Vader", not Star Wars or Gandalf the Grey, not Lords of the Rings. Some of them are famous and well known, others only real Horror Fans can name. (If someone/something hasn't a direct name think about a definition how he/she/it could be called) ;)
