 In 1998, Claremont returned to Marvel and, seeing how Fox was still struggling with the script, sent them a four-page-long memo where he explained the core concepts and what differentiated the X-Men from other superheroes.In late 1998, Singer and DeSanto sent a treatment to Fox, which they believed was "perfect" because it took "seriously" the themes and the comparisons between Xavier and Magneto and Martin Luther King and Malcolm X, unlike the other scripts.They made Rogue an important character because Singer recognized that her mutation, which renders her unable to touch anyone, was the most symbolic of alienation.
