In X-Men: The Last Stand, the climax of the X-Men motion picture trilogy, a “cure” for mutancy threatens to alter the course of history. For the first time, mutants have a choice: retain their uniqueness, though it isolates and alienates them, or give up their powers to fit in. The opposing viewpoints of mutant leaders Charles Xavier, who preaches tolerance, and Eric Lehnsherr (Magneto), who believes in the survival of the fittest, are put to the ultimate test – triggering the war to end all wars.
