X-Men Universe #1

In "Call to Arms!", Jean Grey rallies a new team of X-Folk to rescue Nina and her friends after Xavier disbands the X-Men. When they reach Bastion’s fortress, they find it seized by an unexpected enemy—only to turn the tide and pull Nina to safety.

In "Sins of the Past Part One: In Another Man's Shoes," the Generation X teens awaken to find themselves transformed into the young members of Emma Frost’s former Hellions team—back on the day their past selves were killed by Fitzroy and his Sentinels. Stranded in a moment they were never meant to witness, they must navigate the chaos of a doomed timeline while confronting the X-Men and the ghosts of a history they don’t remember.
