This article contains massive spoilers for "Extraordinary X-Men" #4.
After a few months in the new status quo, Jeff Lemire and Humberto Ramos' flagship X-Men title "Extraordinary X-Men" has potentially answered one of the biggest questions readers have had since the launch of Marvel's "All-New, All-Different" status quo. Again, spoilers lie ahead for those that haven't read "Extraordinary" #4
Fans have wondered about Cyclops' fate since the first issue of "Extraordinary" hit in November. Since then we've gotten scraps of information on Scott Summers' whereabouts and what happened to him during the in-story eight-month gap in between "Uncanny X-Men" #600 and now. We've learned that once the Terrigen Mists started hurting the mutant populace, rendering them sterile, Cyclops took the fight to the Inhumans. This action, the specifics of which have yet to be revealed, left mutants with an even worse reputation and Cyclops presumably dead.
"Extraordinary X-Men" #4 changes that.
In the issue, we learn of X-Villain Mister Sinister's plan. The creepy geneticist is trying to rid mutants of the Terrigen-induced plague that's killing them off. To pull this off, he theorizes that he has to combine the DNA of Inhumans with mutants, although all his tests have proved to be fatal for the mutant test subject. But, as revealed at the end of the issue, Sinister says there was one test subject "who just would not die."
That test subject? Cyclops.
As it's a last page reveal, we don't yet know how Sinister came to possess Cyclops' body and if this is resurrected Cyclops or if the reports of his death were greatly exaggerated. It is clear from the image, though, that Cyclops has a different, presumably Inhuman, look.
"Extraordinary X-Men" #5 arrives on January 13, 2016.
