Pretty much one of the few things I'm worried about over Secret Wars is that whilst the majority of the action is centred around Manhattan, we know there's a lot of characters in other cities and international teams like MI-13, Alpha Flight, Big Hero Six and more. Latveria, Wakanda and Atlantis. Nevermind the rest of the Marvel Cosmic Universe and the Guardians and such.
...so when Secret Wars happens, does that mean all of that now ceases to exist? The way I see it there are three options.
A. They all cease to exist unless they were in Manhattan on Earth at the time of the Incursion. So long guys. (Big clue this might happen, there's an issue of Avengers coming up where most of the 616 aliens show up to Earth to... I dunno, complain about incursions?)
B. There's a 52 situation planned where there's a weekly comic on 616 Earth which is not destroyed and elsewhere, but Manhattan's now gone. Giving all the non New York guys the chance to shine.
C. Some stuff will get erased, but it turns out a few of those unknown locations on Battleworld are other bits of 616! Captain Britain and MI-13 hopped over to Avalon, Iron Fist shifted to Kun Lun, lots of people went to the Savage Land (now the Valley of Flame?). Something akin to that.
So what do you think, are you worried for non-Manhattan characters too?
