The phrase Mutatis Mutandis is Latin and means "that having been changed which had to be changed" or more commonly, "with the necessary changes".
Mutatis Mutandis is the alma mater of Xavier's School for Gifted Youngsters. Charles Xavier and the X-Men recognize that mutants are part of nature, and that they might serve a positive role in society. The world of Mutatis Mutandis is a world where mutants and humans live together. The problems that arise in this world are universal, the feelings of being outcast for differencesthe fear of the unknown. Here is where we enact the lives of these people in the mutant world where Xavier and his students fight for their dream. With the necessary changes, of course.
