Jacqueline Andrea Suzette "Jackie" Tyler (née Prentice), born 1 February 1967 but claiming a birthdate of 1 February 1968, was a resident of early 21st century London in the parallel universe where Pete Tyler was still alive. Unlike the Jackie Tyler from the regular world, this Jackie was an unpleasant woman who looked down on people who she considered to be lower on the social ladder than herself. Nevertheless, like her regular world counterpart, she maintained a fondness for tea and the peculiar little ritual of always having one last cup of tea before bed.
In this universe, Jackie and Pete were still married. They didn't have any children, but they had a dog named Rose. By 2007, Pete had quietly moved out, but he was still involved in planning Jackie's birthday party.
Her EarPods were taken over by the transmitter on John Lumic's zeppelin and told to walk to the Cybus factory where she was one of the first to be upgraded to a Cyberman. She later recognised Pete when he and Rose infiltrated the factory and revealed her identity. The shock of this revelation gave away their non-functioning EarPods. Pete tried to find her again, but neither Rose nor he could recognise her among the hundreds of other identical Cybermen.
