Chris Claremont and John Byrne's collaboration ranks among the greatest comic books have ever known. Their X-Men defined Marvel's mutants, but of their many iconic stories, none was more epic or influential than "The Dark Phoenix Saga." The X-Men fought many battles, set out on adventures that spanned galaxies and grappled with enemies of limitless might, but nothing could prepare them for their most shocking encounter: One of their own teammates, Jean Grey, has gained power beyond all comprehension, corrupting her and transforming her into the Dark Phoenix! They must fight the woman they cherish or the universe itself will be consumed by her unquenchable fire. Also featuring Wolverine vs. Wendigo, the dystopian debut of "Days of Future Past" and more!
