Oh I was going to say what someone else already said I think I didn't see it til a bit ago. Sublime is Apocalyspe or at least possesed him long enough for him to be corrupted. He had his temples and people worshipping him as the perfect example, he was exhaulted and body hoping isn't too new to him when it came to attaining that perfection. Wanting phoenix grafts...wanting X-Man (I know sublime didn't say grafts).
The chaos bringer and order. Genosha was obviously Sublime eliminating genetic varients that would endanger his order. Morrison's whole run was about eliminating mutants to bring order...humans are all the same to an extent but mutants of increasing power pose danger to the world/universe. Beast said he had a cure for that human disease well killing them off or allowing them to be killed off effectively eliminates that disease. And I am assuming most humans are dead in the future because of the flipping of the poles. I doubt Phoenix would have let her friends be atomized by a nuclear blast if it came to that which leads me to my next guess. Kick hehe I wonder who invented that oh I don't know Hank McCoy tired of being the weakling of the team...maybe trying to find a cure for his supposed deevolving or beef up his own powers to Wolverine standards. He would have the genetic expertise to make it. Him taking Kick along with a jumpstart from Sage hmmm.

Well thats what I was thinking but some of it doesn't connect right like the whole Beast making Kick, but then again I can see it if he was Sublime before Riot at Xaviers. I'm wanting to believe that Magneto was Sublime during this time because he had connections to Asteroid M and the Weapon Plus station later on. And Sublime, I think, talks to him through the Xorn persona...when he thought it was Xavier playing mind games.
