10 Best Times Superheroes Switched Sides

Some doubts still remain over whether Game of Thrones actress Sophie Turner can put in a strong enough performance to carry a blockbuster, but if they follow the Dark Phoenix storyline from the comics, Fox certainly won’t have to worry about the quality of the plot.

As one of the quintessential comic book storylines of all time, Dark Phoenix represents one of the most iconic times a hero broke bad. The only reason it has to settle for silver is because it’s so well known, Dark Phoenix is now an indelible part of Jean Grey’s identity.

It features Jean, already a strong and competent mutant, being struck by a solar flare and having her true potential unleashed. This turns her into one of the most powerful beings in existence, and corruption soon follows.

The storyline features several dark turns, eventually causing Jean to have a split personality; Dark Phoenix representing her most primal, violent urges. Professor X is able to control it, only slightly, but trauma often causes it to re-emerge.

As an inescapable part of her, Dark Phoenix essentially lies dormant within her by the end of the saga, constantly bubbling under the surface.
