Flame King (also known as the Chipmunk King) is the former ruler of the Fire Kingdom and Flame Princess' father. He first appears in "Incendium." Jake's mission was to impress him in order to convince him to let his daughter date Finn. After he thinks Finn kills Jake, he releases his daughter and promptly reveals that she is evil. He later appears in "Ignition Point," viewing a play which turns out to be Finn and Jake trying to warn him about an intended regicide.
