S5 e3 Wizad Bill.png

Wizard Bill is the owner of a guitar shop in Ooo. He is the person who gives Marceline the Devil Monster Bass in the episode "Five More Short Graybles". Though he is obviously human, his eyes and hair color looks much like Jake's eyes and hair. It is also unknown if he is a wizard, even though he is called a wizard in his name.
