DC Comics first teased it some 20-25 or so years ago. There have been a seemingly infinite number of fan fiction stories written projecting them as eventually getting married. To a jaded fan like me, this really isn't a big deal after all.
Let me bottom line it for you. Beginning with the new issue of Justice League, in stores tomorrow, writer Geoff Johns & artist Jim Lee have put Superman & Wonder Woman together as a romantic couple. This would explain why, when DC relaunched its universe in the "New 52" initiative a year ago, Superman was no longer married to investigative reporter Lois Lane, ending a 15 year coupling. By the same token, the Amazing Amazon's long-standing relationship with military lifer Steve Trevor was treated as past tense when the "New 52" began.
DC, however, is playing this up as major news, getting ink in the papers and online within the last 24 hours. Two of the company's icons, both of whom had some major tweaking done to them in the "New 52", now the very definition of "power couple". Oh, sure, as fans of the animated Justice League Unlimited are aware, WB tried pairing Wonder Woman with The Batman for a brief time, but that was doomed to fail. It would've been something if DC picked up on it and tried to transfer it to their monthly books, and, yes, there've been fan-fics about Batman & Wonder Woman, too. You have to understand that the classic pairings could eventually be put together anew down the line, but the only way that happens is if the union of a Kryptonian orphan and a Amazon Princess-turned-goddess ends up failing.
Oh, wait, you're saying. Wonder Woman, a goddess? Yeah, that's what was done a year ago. Someone decided that instead of being molded out of magic clay, Wonder Woman was now the daughter of Zeus, which would make her Hercules' half-sister or something. I stopped reading Justice League a few months ago, and I wasn't reading Wonder Woman, so I found out about her altered lineage via a piece in today's New York Daily News. My brain hurts just thinking about it.
I am not sure about how older fans, especially those in my age bracket, are reacting, but as I said at the start, to me, this is not a big deal. I get that DC wants to try something that, to most readers, is relatively new. However, I just don't see this working out in the long term.
Let's say DC pulls the trigger and marries off the two icons. Then, some genius comes along with a radical idea to again reboot the DC Universe, and we're back at square one, and this will have all been for naught. In hindsight, DC was better off leaving well enough alone, and maybe, just maybe, they'll learn that lesson the hard way.
