If you thought everything was going bad for Marvel's superheroes before, apparently it's going to get worse; at Wondercon this weekend, Marvel announced a confrontation between the Dark Avengers and Uncanny X-Men.

The crossover, bringing Marvel's bad-guys-pretending-to-be-good face-to-face with everyone's favorite mutants, starts with June's Dark Avengers/Uncanny X-Men: Alpha, before running through each of the two titles for two months and concluding with another special issue in September. Don't expect this to be a quiet meeting of the teams, though; according to writer Matt Fraction, "[t]his ain't one of those stories that the teams can settle by a rousing game of softball":

Things are certainly dire, and the stakes are certainly high, and through it all there are still no more mutants being born. And this confrontation propels the whole of the Marvel Universe forward, whether it's the Avengers family or the X-Men family of stories. What comes next is as inevitable as the sunrise.
We've both got some big stories to tell — here's where they intersect... It's great – you never get to write like this, so it's a lot of fun. And what comes out of the X-Men/Dark Avengers story is big - it's another game changer on top of the earlier game changers. It's virgin territory for these kinds of stories. The bad guys have never won this big before – this...perpetually before, so it's a blast because we've never gotten to put the heroes through wringers like this before. It's a lot of fun.

That's fun for the readers, of course; there's less chance that the X-Men are going to find themselves laughing and smiling by the time this story reaches its conclusion.
