Warning! Warning! Spoilers for Phoenix #11 ahead!

The X-Men franchise has just confirmed Sara Grey's mutant power, after the stunning return of Jean Grey's sister to Marvel canon at the end of the previous issue, revealing that Sara possesses the critical ability to activate latent mutations, setting her up for a potentially pivotal role in X-lore moving forward, as she explains: "I can unlock someone's full potential."

Phoenix #11, written by Stephanie Phillips, with art by Roi Mercado, follows up on the prior issue's massive revelation of Sara's return; while Marvel's advanced solicitation for Phoenix #12 promises "the secret origin of Sara Grey," this issue largely serves to acclimate Jean to the idea of her sister's resurrection.

More than just a return decades in the making, the confirmation that Sara is a mutant is always a pay-off for years of untapped potential for the character, and so it is fitting that this is actually an aspect of her new role in X-Men in its own right.

footnote in X-lore, and in her sister's story, but now, her return in Marvel's Phoenix ongoing series sets the stage for her to have a much more central role, and a more dramatic arc.

DID YOU KNOW: Phoenix #11...features Sara giving Jean a tour of "Greyhaven," a commune on a distant planet that Sara has founded for latent mutants, those "who have always known they were different, but have been unable to unlock that part of their minds."

Phoenix #11 forestalls an explanation of Sara's survival, but it does establish the fact of her mutant abilities, which have been speculated upon ever since Claremont's run. The issue features Sara giving Jean a tour of "Greyhaven," a commune on a distant planet that Sara has founded for latent mutants, those "who have always known they were different, but have been unable to unlock that part of their minds." Assuming there is no twist, or greater danger, lurking behind this seemingly idyllic community, this could result in a prominent role in X-Men for Sara.

Savvy superhero comic readers know to be weary whenever their hero encounters something seemingly too good to be true; Jean Grey's reunion with her sister Sara, as of Phoenix #11, is a touching moment of joy, but that triumph could quickly turn to tragedy, one way or another.

Readers can't yet rule out that there isn't more to Sara, and her mutant abilities, than the series is letting on just yet.

Meaning, X-fans will immediately feel the impulse to speculate about the implications of Sara's powers on the wider franchise, yet her arc in Phoenix still has to play out before any prognostication can really commence in good faith. Phoenix #12 is slated to be another major piece of the puzzle, promising to explore more of the character's lost history, providing more answers to fans' questions and context for their theories. Beyond that, Phoenix #13 will feature Jean coming into conflict with Cable, and after that, the future of these iconic X-Men characters is an open question.

Phoenix #11 is available now from Marvel Comics.
