Well, first off, I don't think you can take the Amazonian origins out of Wonder Woman any more than you can take the Kryptonian origins out of Superman. Sure, you can reimagine these characters all you want, but you eventually reach a point where it's not an "ultimate" version of the character at all, but instead you have something like the Tangent Universe where names are tacked to characters that don't have much in common with the source. Honestly, I don't think DC should go this route. I love you Jag, but what you're suggesting is beyond unappealing to me. I can see where you're coming from with Green Lantern, but GL is a book about space cops. That's why it's succeeded all these years and the original Green Lantern is little more than a background character. There are essential pieces you need to keep in places to really highlight the strengths of the franchises. It doesn't make a lot of sense. I feel like their core books are pretty entry-friendly. I think the idea behind the UU is something that's run its course. Both companies have done a pretty good job of targeting their books to a broader audience without having to shuttle off a new universe to appeal to the casual crowd. That said, on a creative level, the idea greatly appeals to me.
I'm still proud of the Ultimate DC Universe I sketched out a long time ago. However, I think if it were to be done, you can't go the same route as Marvel. The strength of the Ultimate Universe is that it drew itself back to the core idea of Marvel Comics, the idea that all this could take place in the real world. DC is a different beast, and if they did something like this, they'd need to appeal to what makes their brand strong: rich history and legacy. Here are the things I think would be key to a project of this nature, to create a product that speaks to the strength of DC's characters while sidestepping some of the problems that plagued the UU. Most of them deal with time and legacy, which I feel is the cornerstone of the DC characters.
- A sense of solid progression. If Superman and Batman are going to be the cornerstones (and they absolutely should be), then the books need to be about the progression from Year One to the apex of their careers. These are both characters that came out of the box fully formed. Superman was Superman and Batman was Batman. They were both characters with experience, who were at the top of their game. More than the Marvel characters, these guys are about the journey. How does Bruce Wayne go about becoming the greatest detective in the world? How does Superman become a paragon of virtue and discover his origins.The last 25 years of DC comics have largely been an exploration of the characters' legacy. Writers (I'm looking at you, Geoff Johns) have spent a great deal of time taking the seventy-five years of legacy and constructing a narrative out of it. But with that many writers dabbling, it's a rather patchwork affair. This is an excuse for smart writers to take the decades of lessons learned by their predecessors and apply it to a chronicle of superhero careers without seams. I'd suggest twelve issue volumes, much like Ultimates, with each one covering a year of each guy's career, set to a ten year plan. The restrictions will force writers to make each issue count, because there are clear limitations set. You only have this much space to tell the story of Batman's first year, for instance. It will insure that every issue counts, instead of coasting along with generic Batman/Superman/Whatever stories. It would be similar to the season format of TV shows. I'm looking particularly at The Wire, which was touted as a "television novel". Each volume would be an independent story that provides a perfect jumping on for new readers, but which progresses a narrative. Each volume stands alone in its own right, with a beginning and middle and end and clearly delineated themes and motifs, but also rewards readers who've been picking up the book since the beginning.
- Utilize a small, tight group of writers. This is easy. Look at the Bendis/Millar paradigm. It would be fairly easy to do if you have Superman and Batman as the core books. Put together smart writers who are good at long term storytelling and can work well together. If they have a few year's lead time to work on Batman and Superman before new franchise favorites are introduced, that lays the groundwork for any later writers who come along and sets clear and universal rules. Be frugal in how quickly you introduce new ideas and characters. I'd suggest a universe bible in much the way a lot of TV writing is done.
- Don't purge history just because you don't know what to do with it. Pieces of the past like Justice Society and Blackhawks and pieces of the future like the Legion are important parts of the DC tapestry. The problem comes from utilizing these characters irresponsibly. Batman and Superman's first appearance should mark the beginning of a new age. There's no doubt about that. They're the fathers of the superhero movement. But that doesn't mean there shouldn't have been masked men in WWII, or characters inspired by their deeds in the future. These kind of characters add echoes and resonance to the strength of these guys in the same way that Captain America brought a heritage to Marvel's Ultimate Universe. Just utilize them frugally. I'd suggest yearly summer event minis that focus on the universe's history and its future.
- Keep the fictional cities around. I want Metropolis and Gotham. Half of the strength of Batman and Superman comes from the character of the cities they live in. You can't move Superman to New York and Batman to Boston just to make things easy, and there's no reason this needs to be the "real world". Part of the characters' strengths come from the fact that they live in a world that's much more vivid than ours. Batman should be about detective stories and Superman should be about science adventure, and their cities should reflect this, drawing on modern day and retro elements in much the same way that the WB Batman cartoon did or Azzarello's pulp project seem to be doing.
