Jackie Tyler (Pete's World)

In the parallel universe where Pete Tyler still was alive, he and Jackie Tyler were still married. They didn't have a daughter, but instead they had a dog named Rose. During the attack of the Cybermen on Pete's mansion, Jackie was taken over by her EarPods and told to walk to the Cybus factory where she was 'one of the first' to be upgraded to a Cyberman.

She later recognized Pete and Rose Tyler when they 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 he or Rose could recognize her among the other Cybermen.

Jackie was killed when the emotional inhibitors were shut off, causing the Cybermen to die. (DW: Rise of the Cybermen / The Age of Steel)
