The Maxx, who had a well known 35-issue run in the ’90s, lives in two separate realities, the real world, where he is just a homeless man, and an alternate one, “The Outback,” where he is a huge purple hero. The series will also be a return to Gotham for Keith too, having previously worked on “Arkham Asylum: Madness.”
Given the familiarity Kieth has with the characters, he described the crossover as being like “a family reunion with my favorite brother and our really cool cousin.”
As for what to expect story-wise from the mini-series, here is the official description:
When a devious new doctor at Arkham Asylum conducts unconventional forays into the human psyche, he kicks off a disastrous chain reaction by experimenting on Arkham’s newest patient: The Maxx! The city of Gotham soon begins to merge with the Outback, The Maxx’s psychedelic mental landscape. It’s up to Batman to save Gotham and all of reality… but only by joining The Maxx on a trip into the darkest depths imaginable: the twisted minds of Batman’s greatest enemies!
The first issue of “Batman/The Maxx: Arkham Dreams” will be available in September.
