The Maxx is a homeless bum who lives in alleyways, often inside a cardboard box. He remembers nothing of his life before he was hit by a car, and taken in by freelance social worker Julie Winters.
The Maxx is also the hero and protector of his Jungle Queen (who greatly resembles Julie) in the land known as The Outback. While in The Outback, Maxx wears a headdress resembling those worn by Native tribes.
