Elizabeth "Betsy" Braddock is a British mutant telepath who has acted both alongside the X-Men as Psylocke, and as a champion for Otherworld as Captain Britain. While her twin brother Brian became the original Captain Britain, Betsy developed psychic powers. By serving in S.T.R.I.K.E. Psi Division, her path as a secret agent crossed with her brother's super hero activities. She acted as an ally to her brother in several conflicts, eventually adopting the Captain Britain mantle. Blinded by the villain Slaymaster, Braddock stood down as Captain Britain, only to be captured and to have her sight restored by Mojo and Spiral. Rescued by the New Mutants and the X-Men, Braddock joined the ranks of the latter as Psylocke. As a member of the X-Men, Braddock has experienced unimaginable adventures. Her life got unexpectedly twisted when her body was switched with Kwannon, an assassin ninja. Freed by Wolverine, Psylocke returned to the X-Men having to cope with the experience of being stuck in another woman's body. For years, she was a loyal soldier to the X-Men, collaborating with different squadrons and paying the ultimate price when she was slain by the villain Vargas. Resurrected by her older brother, Jamie, Psylocke resumed her adventurous lifestyle by accompanying the X-Men and other groups, such as the multiversal Exiles and the lethally destructive X-Force. Braddock's issues with her body swap were unexpectedly solved after she was seemingly killed by Sapphire Styx and was able to recover in her original body. Soon after, all mutantkind was invited by Professor Xavier to live on Krakoa. There, she rejected the name Psylocke and was involved in Apocalypse's machinations to recreate the mutant group Excalibur. As a result, Betsy Braddock resumed her one-time role as a mutant Captain Britain, becoming the prime champion of the Captain Britain Corps.
