Elizabeth "Betsy" Braddock is the daughter of Dr. James Braddock. His first child, Jamie, seemingly did not inherit genes from his father that would result in superhuman powers. But Braddock's next children, the twins Brian and Elizabeth, did inherit such genes. Brian eventually became Captain Britain. Betsy developed psychic powers, which she used in service of the law-enforcement agency S.T.R.I.K.E. When Brian gave up the role of Captain Britain, his sister was persuaded to take up the mantle. But Betsy's career as Captain Britain came to a quick end when she battled two of her predecessor's foes, savagely beaten until she was near death and blind.
Realizing her telepathic abilities compensated for her blindness, Betsy went to Switzerland to recuperate. There, she became prisoner of the otherdimensional creature Mojo, who took control of Betsy's will and gave her artificial eyes. Ultimately, she was rescued by the New Mutants and brought to Professor Charles Xavier's mansion to live. Betsy became a full-fledged member of the X-Men. Now known as Psylocke, she shared many adventures with the band of mutants. Betsy was captured by the Mandarin, who transferred her essence into the Asian body of Hand assassin Kwannon.
