The Maxx (MTV's Oddities, 1996)

This series follows the adventures of the titular hero in the real world and in an alternate reality, referred to as the Outback. In the real world the Maxx is a vagrant, a "homeless man living in a box", while in the Outback he is the powerful protector of the Jungle Queen. The Jungle Queen exists in the real world as Julie Winters, a freelance social worker who often bails the Maxx out of jail. While the Maxx is aware of the Outback, Julie is not, though it is integral to both of their stories.

Due to suggested scenery of violence, adult situations, and what not (they are not as much as "seen" as suggested, and even those are in "mildly juvenile" as is) it is probably a good idea for "more mature audiences" to view this animated series before "less mature audiences" get a look at it (this is not your everyday "kids cartoon", despite some appearances to the contrary).

The Maxx is also a graphic novel series, originally published under the DC and Wildstorm labels. This cartoon, apparently, made it (story line wise) about half way through the comic book series before facing "sudden cancellation".
