20 Best Female Characters In Comic Book Movies - Ranked
11. Mystique (Rebecca Romijn)
Not Jennifer Lawrence (although her First Class iteration is just about bearable). In X-Men 1-3, the coolest of the Brotherhood of Mutants wasn't Sabretooth, Pyro or even Magneto - no, it was Magneto's most trusted henchwoman, the shapeshifting Mystique.
A cool, mysterious and nebulous figure, Rebecca Romijin's appeal was in her, uh, mystique. Capable, wry and popping up wherever you least expected her (the twist at the end of the first movie is the franchise's best), Mystique was utilised just enough to not outstay her welcome, unlike some X-Men we could care to mention.
Even more impressively, she got X-Men: The Last Stand's single-most powerful moment, as Magneto abandons her once the Mutant 'cure' takes hold and she loses her powers. Quietly heartbreaking, in exactly the manner that the Last Stand's Dark Phoenix saga should have been, and wasn't.
