Therefore, there's no way 616-Peter Parker will be erased just like that.
Anyway, I just realized there's another big problem around here. You see, if there's absolutely nothing else in the Marvel's multiverse except battleworld, that gives one big problem. What happens when somebody dies? I mean, if there's no place for death people to go, I pressume they can't actually die after all. If fact, I have a theory. We saw King Thor being killed in "Secret Wars #2", but we saw him appearing in a preview of "Future Imperfect #1". So, my theory is that, when someone dies in one of these "domains", he's simply sended to another domain and resurrect. Sounds weird, but we have discovered weirder things already about Battleworld.
