Scott Cawthon (otherwise known as The Storyteller or Omega Scott) is both a real person and the final boss of FNaF World.

His appearance is a three-dimensional representation of the developer's icon/avatar which came from one of his previous games, called "There is No Pause Button!", appearing as couple of cubes in the form of a figure. He glows with an entirely light blue light.
