Created by writer/editer Stan Lee and artist/co-plotter Jack Kirby, the team first appeared in The X-Men #1. Although initially cancelled in 1970 due to low sales, following its 1975 revival and subsequent direction under writer Chris Claremont, it became one of Marvel's most recognizable and successful franchises.
