The series character designs were based on the artwork of comic book artist Jim Lee's designs from the "X-Men" comics. The X-Men roster comes from the Blue Team (with Storm and Jean Grey replacing Psylocke and Revanche) that was featured in the "X-Men" comic (the second volume) around the time of the series began production. The first issue was ranked by the Guinness Records as the best-selling comic of all time.
