I really, really love Mike Allred, however I still have not read all of his most well known work, Madman. Fortunately, Image comics is currently rereleasing the entire series in some beautiful editions.
This series is great fun, and plays to all of Allred's strengths, both as a writer and an artist. It's clear that Allred just had a blast in the creation of each issue. Madman, an amnesiac, acrobatic, precognitive, lab assistant and sometimes superhero, is just a bizarre character with tons of story potential. The world which he inhabits is equally brilliant, allowing for mad scientists, G-Men from Hell (the inspiration for the movie), puke monsters, and tons of robots who all seem like mundane parts of Snap City. The only thing that detracts from this is that at the time these were written, then publisher Dark Horse, decided to have all of their pseudo-superhero character inhabit the same world. Thus this book contains a glaring cameo from Mike Mignola's Hellboy (little more than a visual gag), and a slightly more fitting one from Frank Miller and Geoff Darrow's Big Guy. But the book as a whole lives up to it's subtitle, "the world's snappiest comic magazine!"
