At first, I believed Supreme to be Alan Moore’s proto-Tom Strong: an archetypical comic book strong man with half a century of untold backstory. But what he’s done with that book (offshoots of which are still currently being printed) and what he did with this Superman knockoff in the mid-to-late-90s are very different indeed.
Supreme is, essentially, the entire history of Superman and his contemporaries, told in a unique-yet-reverent manner. By using a character that evokes the original, rather than the original himself (which one doubts DC would have any problems handing over to a writer of such stature), Moore is able to throw in bizarre twists that might not work in an established continuity.
For instance, in the first issue (a good 50 issues into the series, but Moore’s first), Supreme is greeted by a gaggle of “alternate” Supremes that escort him to a world populated entirely by discarded and unused variants on the character. Supreme, for reasons not understood to each of them, experiences periodical “restarts,” resulting in a clean slate for the new guy, and a glorious retirement home for the previous versions. In other words, this is the place that bad ideas go when they die. I had trouble with the concept at first, and I’m certain I’m not doing it justice with this explanation, but trust me: it’s actually pretty cool. Supreme returns to his life, realizing that he has large gaps in his memory (backstory) that demand being filled in.
Subsequent chapters find him restoring order to his current surroundings, with frequent flashes back to his “Golden Age” and “Silver Age” adventures. He recovers his Supergirl, his Krypto the Wonder Dog and his Justice League, while also maintaining his nerdish alter-ego, who just happens to write comic books for a living.
In all, Supreme is a celebration of the superhero comic. Perhaps most fantastic of all is Moore’s ability to cover this familiar ground (trodden not only by him, but also by Kurt Busiek’s Astro City and others) in a way that comes across as unique and entertaining. But then, I’ve yet to find anything written by Mr. Moore that accomplishes any less.
