10 Best X-Men Costume Redesigns
4. Dark Phoenix
The Dark Phoenix Saga has been one of the most iconic X-Men storylines ever. As the Phoenix Force possessed and corrupted Jean Grey, she became a danger not only to her friends but as well as the entire universe. As it grew more powerful, the Dark Phoenix also consumed planets and killed millions of living creatures.
Swapping her green and yellow colours for a dark red, Grey as the Dark Phoenix bared a sinister visage as the cosmic force possessed the young woman. With her eyes losing humanity and her face having an otherworldly expression, the Dark Phoenix became one of the X-Men's biggest foes. Torn between the safety of the universe and their loyalty to their friend, this eventually led to a climactic duel between the X-Men and the Shi'ar Empire. Ultimately, Jean chose to die as a mortal rather than be consumed by god-like power.
While she has been resurrected numerous times, Jean's turn as the Dark Phoenix remains a classic in the X-Men's rich and colourful history.
