X-Men: The Hidden Years

The X-Men: The Hidden Years series from Gotham Entertainment Group, published between 2003 and 2004, fills a gap in the original team's history, exploring the adventures that occurred between the classic Lee/Kirby run and the later revival by other creators. Over its 14-issue run, it focuses on the early, lesser-seen era of the X-Men, emphasizing their struggles as a young, secretive team. For fans of the original X-Men, this series offers a nostalgic, continuity-minded look at a transitional period.
