X-Men: Legion Quest

In 1995, Marvel's X-Men: Legion Quest was a single-issue prelude crafted by writer Fabian Nicieza and artist Andy Kubert. It set the stage for the sprawling "Age of Apocalypse" event by focusing on Legion, the reality-altering son of Professor X, whose desperate act to change history would reshape the entire X-Men universe. Though brief, this issue served as the crucial catalyst for one of the most ambitious and acclaimed alternate-reality sagas in X-Men history.
