“Matt came to us with a really interesting and unique approach to bringing Jean back,” senior editor Mark Paniccia said in an official statement. “It’s not what we expected, and plays to Matt’s biggest strengths as a storyteller. This is very cool mystery building to a mind-warping climax. And it has plenty of what you’d expect from an X-MEN epic of this magnitude. Action, romance, sacrifice, lots of X-Men and five great artists.”

“It's such a mind-blowing honor to bring back the original Jean Grey,” Rosenberg said of working on his and Yu's series. “I've been an X-Men fan my whole life and Jean is, in my mind, the true soul of the X-Men. So we aren't taking this lightly. We're going for that perfect balance of universe shaking epic and intimate personal drama that only the X-Men ever truly achieve. This is all hands on deck for the X-Men as every available member heads into battle for the soul of their team and maybe even the fate of the Marvel Universe.”

As part of the announcement, Marvel also confirmed that Rosenberg has signed an exclusive deal with the publisher.

The Phoenix has seen a rise in profile across the Marvel Universe in recent months. Not only is the cosmic entity at the heart of the current Jean Grey serieshttps://www.cbr.com/jean-grey-secret-of-phoenix-revealed-x-men/ (written by Dennis Hopeless), which follows the adventures of a time-displaced teenage version of the popular original X-Man, it will also be part of the publisher's upcoming Marvel Legacy one-shot. There, in a story by Jason Aaron and Esad RIbic, the Phoenix will be part of the original Avengers team from 1,000,000 BC. What's more, she will be in a romantic relationship with Odin, a revelation readers first learned of in the Generations: Thor one-shot.

But that's the Phoenix entity, not the long-dead adult Jean Grey. How she will be tied to the Phoenix power this time around, and what the implications her return has on the younger Jean Grey remain a secret for now, but fans should probably expect answers (and probably a few more questions) to be revealed in pages of both Phoenix Resurrection, and Jean Grey.
