Katherine Anne "Kitty" Pryde is a superhero appearing in American comic books published by Marvel Comics, commonly in association with the X-Men. The character first appeared in The Uncanny X-Men #129 and was co-created by writer-artist John Byrne and writer Chris Claremont. A mutant, Pryde possesses a "phasing" ability that allows her to pass through objects, hence she is intangible while using this ability. This power also disrupts any electrical field she passes through, and lets her simulate levitation.

The X-Men are a superhero team appearing in American comic books published by Marvel Comics. 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. They have appeared in numerous books, television shows, 20th Century Studios's X-Men films, and video games. The X-Men title may refer to the superhero team itself, the eponymous comic series, or the broader franchise including various solo titles and team books such as the New Mutants, Excalibur, and X-Force.
