The Dark Phoenix Saga

The Dark Phoenix Saga is the definitive X-Men story — a tragedy about power, corruption, and sacrifice that redefined what superhero comics could be. Chris Claremont and John Byrne built to this climax over years of careful plotting, and the result is one of the most emotionally devastating stories in comics history. Jean Grey's transformation from hero to cosmic threat, and the X-Men's desperate attempt to save her, remains the gold standard for event storytelling.
