The X-Men is a fictional team of superheroes appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist/co-writer Jack Kirby, the characters first appeared in The X-Men #1 (September 1963). They are among the most recognizable and successful intellectual properties of Marvel Comics, appearing in numerous books, television shows, films, and video games.
The X-Men are mutants, a subspecies of humans who are born with superhuman abilities. The X-Men fight for peace and equality between normal humans and mutants in a world where antimutant bigotry is fierce and widespread. They are led by Charles Xavier, also known as Professor X, a powerful mutant telepath who can control and read minds. Their archenemy is Magneto, a powerful mutant with the ability to generate and control magnetic fields. Professor X and Magneto have opposing views and philosophies regarding the relationship between mutants and humans. While Professor X works towards peace and understanding between mutants and humans, Magneto views humans as a threat and believes in taking an aggressive approach against them, though he has found himself working alongside the X-Men from time to time.
Professor X is the founder of Xavier’s School for Gifted Youngsters at a location commonly called the X-Mansion, which recruits mutants from around the world. Located in Westchester County, New York, the X-Mansion is the home and training site of the X-Men. The founding five members of the X-Men who appear in The X-Men #1 (September 1963) are Angel (Archangel), Beast, Cyclops, Iceman, and Marvel Girl (Jean Grey); Professor X and Magneto also make their first appearances in The X-Men #1. Since then, dozens of mutants from various countries and diverse backgrounds have held membership as X-Men.
Psylocke (Elizabeth “Betsy” Braddock) is a fictional superheroine appearing in American comic books published by Marvel Comics, commonly in association with the X-Men. Created by writer Chris Claremont and artist Herb Trimpe in 1976, she first appeared in the Marvel UK series Captain Britain.
Betsy was initially a supporting character in the adventures of her twin brother, Captain Britain, even briefly substituting for him in the role, before becoming the mutant superheroine and X-Men member Psylocke in 1986. Originally presented as a precognitive in the pages of Captain Britain and then as a telepath, the character eventually had her mind placed in the body of a Japanese female ninja known as Kwannon, gaining many of Kwannon’s martial arts skills and elements of her personality. Psylocke’s codename, coined by the X-Men villains Mojo and Spiral, debuted during her introduction to the X-Men stories post–Captain Britain. Later, Psylocke acquired the power of telekinesis.
Many alternative versions of Psylocke have also appeared in several comics series of Marvel Multiverse, as well as in various other media and merchandise, notably in numerous video games. She briefly appeared in the 2006 film X-Men: The Last Stand, where she was played by Meiling Melançon. Olivia Munn portrays her in the 2016 film X-Men: Apocalypse.
