The X-Men are a superhero team in the Marvel Comics Universe. They were created by writer Stan Lee and artist Jack Kirby, and first appeared in The X-Men #1 (September 1963). The basic concept of the X-Men is that under a cloud of increasing anti-mutant sentiment, Professor Xavier created a haven at his Westchester mansion to train young mutants to use their powers for the benefit of humanity, and to prove mutants can be heroes.
