The Pope

In Italian fokelore, The Pope is a monster said to inhabit Vatican City. He has disguised himself as a popular religious figure as to avoid suspicion from the masses. Scientific name: Pontifex maximus.
He primarily feeds upon his followers. When they stray from the pack during mass, he deploys his body double and stalks over to the lone straggler and draws them towards him with his mind control powers. He then devours them whole, leaving no trace of their existance.
He is able to shapeshift and if you stare deeply into his steely, dark grey eyes, his pupils will turn into slits and he will unhinge his jaw and devour you whole like a snake. He will leave no proof of your existance, thanks to his connections to the FBI, CIA and KGB, your idenity will be erased, rendering his crime unsolvable.
