The moon's launched a slew of meteors at Earth, and each one that lands will transform into a giant monster. It's just one of those days...
The rest of the team pops over to Colorado, where Jack tries to make contact with this ancient, mystery city, while his teammates try to keep the monster from killing him before he gets a chance to.
Over at Newsarama, Cornell explained some of the ideas behind Adam One in an interview (http://www.newsarama.com/comics/cornel
"He's a Boltzmann Brain. The theory goes that — and this will not appear in the comic at all — unless I do a Warren Ellis-style aside at some point about it — but as the theory goes, if we live in a genuinely infinite universe, there will, at some point, simply spring into existence intelligences. And that first moment after the universe was born would be a good moment for them. So he is one of those individuals, one of those people. He was formed simply out of sheer chance in the first moment of cosmic expansion. Or perhaps out of order — there may have been a great purpose behind it. Who knows?
He's been aging backwards ever since, perhaps because he got on the wrong end of that moment when time stopped being a dimension of space and became something a bit different.
I'm talking a fantastic game here, but none of this will show up in the title."
