The Negative Zone

Is the Negative Zone its own dimension/universe, or are there parallels in the multiverse? Is there only one Negative Zone, or is there one for 616, 842, 50852, etc?

Thanks Monolith.  Yeah I've been re-reading Annihilation, and I remembered the whole Blink/Annihilus thing.  Kinda gave me a headache, haha.  If there is indeed only one Negative Zone, and positive universes are encroaching on it, I can't imagine how quickly the Zone must be shrinking, as there are an infinite amount of universes growing into Negative Zone space.

But then again, I suppose it makes total sense for each universe to have their own Negative Zone (the yin/yang thing).  But it does beg the question as to why Human Annihilus would remember the 616 Fantastic Four.  I suppose it would also make sense for the Negative Zone to be a sort of "in-between" dimension to all realities, though you would think they would have more travelers than just the people from 616.  With an infinite amount of universes, you would think a lot more of them would use the Negative Zone to get to other places - for example, that could be a mighty convenient way for Nova and Starlord to get back to 616 from the Cancerverse.  (Though if there are lots of travelers in the Negative Zone from other universes, it's entirely likely that we haven't heard about them because we are primarily concerned with the 616verse.)

There are definitely alternate reality Negative Zones connected to various alternate Earths. We've seen too many alternate versions of the Zone and of Annihilus for it to be in doubt. However, the Zone's instability does seem to intermittently put it into contact with other realities, so you sometimes can use it to transit from one alternate Earth to another.
