Santa Claus, Various movies
Let’s just start with the big red guy, because he’s slaughtered so many. Across films like Silent Night, Deadly Night (and its sequels), Tales From the Crypt, Christmas Evil, and Rare Exports: A Christmas Tale, and TV shows like Futurama and American Horror Stories, jolly old Saint Nick has amassed a body count that would make the likes of Michael Myers and Jason Voorhees take notice. You know how it goes: he sees you when you’re sleeping. He knows when you’re awake.
