After Xavier is saved, he mentally links with her and reveals to Apocalypse that he is not the most powerful psychic, and convinces Jean to unleash the full extent of her powers. Her eyes glowing with fiery light, the powerful young Mutant walks through midair and within a matter of seconds, a massive burst of telekinetic energy (combined with fire generated by Magneto piling metal into Apocalypses' shields) explode outward from within Jean's body, almost instantaneously taking the shape of a great, fiery bird. Her powerful telekinesis dispels Apocalypse's shield, and aided with Cyclops, Storm and Magneto, they weaken the Apocalypse altogether. Until finally, as she gets more powerful, the fire reaches to Apocalypse's physical body, and she incinerates Apocalypse before calming down. She helps to psychically restore and revive Professor Xavier. She is last seen helping to re-build the mansion, alongside Erik Lensherr, before joining Cyclops, Storm, Nightcrawler, Quicksilver, under the leadership of Hank and Raven, to become the new official team of X-Men and preparing to test her powers in her very first Danger Room session against a group of Mark I Sentinels.
