Ose

Ose is a Great President of Hell, ruling three legions of demons. He is depicted as a leopard that after a while changes into a man.

He makes men wise in all liberal sciences and gives true answers concerning divine and secret things; he also brings insanity to any person the conjurer wishes, making them believe that they are the creature or thing the magician desired, or makes that person think he is a king and wearing a crown, or a Pope.
