Apesh
Apesh was an Ancient Egyptian god of the night who had the head of a turtle or tortoise. He was considered to be an evil god because turtles were considered to be an evil animal and Apesh represented them. In the Book of the Dead the turtle and by extension Apesh is depicted as an "enemy of Ra"; in chapter 161 of the Book of the Dead, Thoth is quoted repeating "May Ra live and turtle die".
