Ammit, known as the Devourer of the Dead is one that you do not want to see in the afterlife. To be fair, she wasn't worshiped as much as feared. Ammit was a demon composed of the biggest animals that could eat an ancient Egyptian: lion, hippopotamus and crocodile. Head of a crocodile, front body of a lion, back body of a hippo.. Once you died, the god Anubis weighed your heart against the feather of Ma'at. If the heart was heavier than then the feather, it was "impure," and Ammit would eat it.
