William is a massive 7 foot tall anthropomorphic male lion, with a massive and imposing mane of golden fur around his neck, and a long feline tail flicks back and forth behind him. He has a musky hypnotic stench that some people find very arousing. His hands are massive paws, and he has big musky and sweaty footpaws that he loves to press against people. He is a very fatherly lion, and runs a store of magic artifacts that turn people into different kinds of animals.
