Elizabeth "Betsy" Braddock is the twin sister of Brian Braddock, aka Captain Britain. Originally a charter pilot and model, Betsy developed mutant Psychic abilities which she used to join the X-Men as Psylocke. Saving her teammates from the Reavers, and found unconscious on the coasts of Japan, Psylocke's mind and soul were swapped with that of a dying Japanese assassin.
