Ammit is a creature that appears in Egyptian folklore as a hybrid animal with the lower body of a hippopotamus, the upper body of a lion or bear, the head of a crocodile, and the mane of a lion.
This monster is commonly rendered as a carnivore, eating hearts, carcasses, and occasionally, souls. When somebody was taken into the afterlife, Anubis, the guide, would weigh the person's heart, and ask the person a question about themself. If the person lied, Anubis would push the person over to Ammit, (always hungry) who would consume the person, eating them, soul, heart, and all. The person would then be transported to the Underworld.
