This is my favorite animated series ever, and I say that without hesitation. It is also a graphic novel adaptation, which too is absolutely excellent.
The series follows the adventures of the titular hero in two worlds: The real world and an alternate reality referred to as the Outback (presumably named metaphorically after the real Australian outback). In the real world, Maxx is a vagrant, a “homeless man living in a box”, while in the Outback, he is the powerful protector of the Jungle-Queen, who exists in the real world as Julie Winters, a freelance social worker who often bails Maxx out of jail. While Maxx is aware of the Outback, Julie is not, though it is integral to both of their stories.
I highly recommend this one. Here is a VHS rip of the whole series, which is a superb way to watch it.
I have the novels in storage, I’m now thinking of breaking them out for the first read in 14 years.
