WHO-IS: "Psylocke (Elizabeth "Betsy" Braddock) is a fictional superhero 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. 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 will portray her in the 2016 film X-Men: Apocalypse."
