Jackie Tyler (Pete's World)

In the parallel universe where Pete Tyler was still alive, Jackie Tyler and he were still married. They didn't have any children, but 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 recognised 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 Rose nor he could recognise her among the hundreds of other identical Cybermen.

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