Jean Grey's new status quo as cosmic defender Phoenix reaches new heights, as she faces off against Marvel's biggest cosmic villain - Thanos! Jean Grey has been going toe-to-toe with some of the universe's toughest foes, but now a new threat is brutally asserting his dangerous reputation: none other than Thanos. And while Phoenix singlehandedly battled back the Black Order, their nefarious progenitor - and his mysterious connection to Jean's many galactic enemies, like Perrikus and the Dark Gods - is another story entirely. To have a hope of victory, Jean will need to reach out - beyond the limits of her own powers - and find allies to take a stand against the Mad Titan! With warriors like Captain Marvel, Nova, Sif and Rocket Raccoon at her side, maybe she has a chance. But when Jean ascends to her most powerful form ever, will she struggle to hold on to her humanity? Collecting: Phoenix (2024) 6-10
