Ammit

In ancient Egyptian religion, Ammit (also spelled Ammut and Ahemait, meaning Devourer or Bone Eater) was a female Goddess and demon with a body that was part lion, hippopotamus and crocodile. A funerary deity, her titles included “Devourer of the Dead,” “Eater of Hearts,” and “Great of Death.”
Ammit lived near the scales of justice in Duat, the Egyptian underworld. In the Hall of Two Truths, Anubis weighed the heart of a person against the ostrich feather of Ma'at, the goddess of truth. If the heart was judged to be not pure, Ammit would devour it, and the person undergoing judgement was not allowed to continue their voyage towards Osiris and immortality. Once Ammut swallowed the heart, the soul was believed to become restless forever and would be erased from exitance, which was called "to die a second time". 
Ammit was also sometimes said to stand by a lake of fire. In some traditions, the unworthy hearts were cast into the fiery lake to be destroyed. Some scholars believe Ammit and the lake represent the same concept of destruction. Ammit was not worshipped, instead she embodied all that the Egyptians feared, threatening to bind them to eternal restlessness if they did not follow the principle of Ma'at.
