The first appearance of The Maxx was in Primer #5 (September 15, 1983).
The Maxx is a comic book and animated series written and illustrated by Sam Kieth (with writing assistance from William Messner-Loebs earlier on in the series and from Alan Moore in a later issue), and published by Image Comics. The first issue was published in March, 1993.
The series follows the story of The Maxx, a homeless man who believes he is a superhero. The Maxx shifts between the real world and a dream world, which he refers to as The Outback, which is just as real to him as the real world. His only friend is Julie Winters, a “freelance social worker”. Little does she know that she and The Maxx have a deeper connection, and it involves the dream world into which The Maxx is constantly drawn.
