X-Men

Founded by Professor Xavier from the ranks of his most promising first students, the X-Men take a still more proactive role in furthering Xavier's vision of peaceful mutant-human relations. Whereas the school does this by teaching young mutants to use their gifts safely and ethically, the X-Men do this by working to protect the world, even those parts of it that hate and fear them. A team of highly-trained mutants, the X-Men work both to combat persecution of innocent mutants by humans, and also to combat mutants who use their powers in hostile and destructive ways. Many but not all of the teachers at Xavier's are part of the team, though it also includes others -- former Xavier's graduates, or mutants who have allied themselves with the school. An open secret among the student population at the school, students are not allowed to join the ranks of the team until graduation, though many of the more promising students are offered extra training if they seem like good fits for eventual membership.
