X-MEN THE HIDDEN YEARS # 1 * JOHN BYRNE * MARVEL COMICS *

John Byrne launches The Hidden Years by stitching a brand‑new storyline directly into the gap between the original X‑Men run and Giant‑Size X‑Men #1. The issue works as a “lost era” opener, reuniting the classic team—Cyclops, Marvel Girl, Beast, Iceman, and Angel—right after the events of X‑Men #66.
