Cassius

Cassius is a demon of gluttony thousands of years old who's primary form is an infinitely regenerating worm. The inside of his body would look like this. He often disguises himself as a human priest or doctor to gain access to people to eat. He's loosely based on the stories of Tarrare and like him has the ability to eat anything. In his human form he has long dark brown hair and pale olive toned skin. His eyes are grey and he usually wears glasses. He is very tall and skinny. He has no genitals. He can morph his body into many shapes, with some restrictions. When half-way between man and worm all his claws, horns, and other hard appendages are made of teeth.
