For the most part, SIEGE has dealt with mainly the Avengers characters. According to the Siege Checklist, the only mutant title that was part of Siege was Dark Wolverine. That makes perfect sense since Daken is part of the Dark Avengers. It appears that Dark Wolverine is not the only mutant title getting involved. Siege will be spilling into the New Mutants as well.
It seems a little weird that of all the X-titles, it's the New Mutants that officially enter Siege. I suppose with Second Coming on its way, there's not a lot of room for the other X-books to take part. I wonder if this is for the best. I've enjoyed the X-events being contained to the X-books, sort of like they're in their own little universe. Then again, since Siege is such a huge part of the Marvel Universe, it almost feels like the X-Men are being short-changed. I'm sure if Second Coming wasn't looming, there would be more involvement. Is this best for the X-Men and the Marvel universe or are there just too many events going on at the same time?
SIEGE BLOCKBUSTER TIE-IN!! Back in DARK AVENGERS/UNCANNY X-MEN:UTOPIA, Dani Moonstar made a deal with Hela. Now, the mistress of Hel is calling in her marker. With all the Asgardians falling in the Siege of Asgard, someone needs to deal with the dead. And who better to do so than a Valkyrie. But where is Dani supposed to be bringing these dead? Brought to you by a guest creative team of Kieron Gillen (THOR, S.W.O.R.D.) and Niko Henrichon (PRIDE OF BAGHDAD).
And let's hope that this issue of New Mutants has some relevance. I'm a little concerned since this issue has a "guest creative team" and issue #12 is "Second Coming Chapter Three." It almost feels like a cheap ploy to just throw the New Mutants into Siege for one issue. But at least we'll get to (hopefully) see Dani kick some butt.
