Ammit The Devourer

Ammit is a spirit that Hades created soon after the dawn of the human race to further punish those who were sent to Hell. Ammit has the head of a crocodile, the mane of a lion, the body of a leopard, and the hindquarters of a rhino. This spirit was tasked standing in front of The Duat's entrance to Hell and eating the hearts of anyone who goes down that path to send them to Hell. The only one who has been known to defeat the beast was Weasel, who had been sent there to test his mettle against the beast to prove his worth to Ra. After Weasel defeated Ammit, Weasel still ended up in Hell via a portal behind Ammit, while Ammit simply respawned after a few minutes.
