In the comic books, Psylocke was created by Chris Claremont and Herb Trimpe for the British "Captain Britain" series, where she appeared in the 70s and 80s, before joining the X-Men in 1987's "Uncanny X-Men" No. 213. Since that time, she has been a mainstay both of the main team and spin-off series including "Exiles" and "X-Force."

Psylocke was originally presented as a precognitive in the pages of "Captain Britain" and then as a telepath. She eventually acquired the body, skills and elements of personality of a Japanese female ninja known as Kwannon.

Later, Psylocke managed to acquire the telekinesis of Jean Grey.

"X-Men: Apocalypse" is due out on May 27, 2016 and is currently in production.
