Demons
Demons were more powerful than human beings but not as powerful as gods. They were usually immortal, could be in more than one place at a time, and could affect the world as well as people in supernatural ways. But there were certain limits to their powers and they were neither all-powerful nor all knowing. Among demons the most important figure was Ammut – the Devourer of the Dead – part crocodile, part lioness, and part hippopotamus. She was often shown near the scales on which the hearts of the dead were weighed against the feather of Truth. She devoured the hearts of those whose wicked deeds in life made them unfit to enter the afterlife. Apepi, another important demon, (sometimes called Apophis) was the enemy of the sun god in his daily cycle through the cosmos, and is depicted as a colossal snake.
