Elizabeth Braddock first appeared in Captain Britain #8 (Dec. 1976), published by the Marvel Comics imprint Marvel UK. There, writer Chris Claremont introduced her as a supporting character, the sister of Brian Braddock, the eponymous Captain Britain, and established her career as a charter pilot. He also established that she had psychic abilities, the full extent of which were unknown, though no explanation is given for these powers. In Marvel UK's Super Spider-Man and Captain Britain #243 (Oct. 1977), Betsy Braddock is presented as a professional model.
In Marvel UK's Daredevils #3 (March 1983), Alan Moore establishes that the character has begun to work for the fictional governmental organization S.T.R.I.K.E., who are making use of her psychic abilities. Her lover Tom Lennox is also a S.T.R.I.K.E operative, who is later murdered. The story also presents the character as having dyed her hair purple; this hair color has subsequently become the dominant presentation of the character. The next major change for the character came in the 1986 relaunched Captain Britain series, where Betsy Braddock stands in for her brother as Captain Britain, and as a consequence rendered blind at the hands of the supervillain Slaymaster.
