Peter Tyler (Pete's World)

Peter Alan Tyler, commonly known as Pete Tyler, was a parallel universe counterpart of Pete Tyler, father of Rose Tyler and husband of Jackie Tyler.

Bought out by Lumic
Unlike Rose's deceased father, the Pete Tyler of a parallel world was a wealthy businessman. He was head of Vitex, a firm that made soft drinks and a subsidiary of Cybus Industries, which was run by John Lumic.

He was married to Jackie Tyler. They had no children, but did have a dog they called Rose. Shortly before Jackie's fortieth birthday, Pete and Jackie got divorced but kept it quiet as it was bad for business. He threw a party for her, but she was annoyed with him as he had put that she was forty on the banner, not thirty-nine, which she wanted it to say. That day, Pete had attended a meeting aboard John Lumic's Zeppelin.

In this meeting Lumic told Pete and the others of his plans to change humans into Cybermen. The President prohibited it. Pete tried to make Lumic feel better, telling him England was not the only country in the world. (TV: Rise of the Cybermen)

Fighting the Cybermen
During Jackie's party, Cybermen broke into the house and started killing the guests. Pete escaped with the Tenth Doctor, Rose and the Preachers. They were surrounded by the Cybermen, who threatened to delete them, as they were "incompatible for upgrading". (TV: Rise of the Cybermen) Before they were deleted, the Doctor used an Artron power cell to defeat the Cybermen, and they fled in the Preachers' van driven by Mrs Moore.

As they drove away, Pete revealed he had been secretly feeding information to the Preachers, under the code name "Gemini". (WC: Tardisode 5) He took part in the plan to stop the project, disguising himself using dead EarPods. He and Rose entered the Cyber Factory and waited to be "upgraded". The plan failed. A Cyberman approached after overhearing their conversation and revealed itself to have been Jackie, which exposed Pete's emotions by causing him shock and horror.

Pete was taken with Rose to the Cybermen's control centre and watched as the Doctor spoke with the Cyber Controller that had been John Lumic. The Doctor made them feel emotion by inputting the code which broke the emotion inhibitor. As the factory started to burn, Pete and the others escaped to the roof. Jake Simmonds and Mickey Smith lowered a ladder from the Zeppelin they were flying so the others could climb up. The Cyber Controller grabbed onto the ladder as well, but was sent tumbling into the exploding factory after Pete used the sonic screwdriver to break the ladder under him. He found out Rose was actually the daughter of his parallel self from the Doctor's universe. Because he and his Jackie had not had a daughter, he simply walked away stunned, under the pretence of helping the Preachers. Rose and the Doctor then departed in the TARDIS. (TV: The Age of Steel)

Saving the Earth
After saving his world from the Cybermen, Pete joined Torchwood along with Mickey Smith and Jake Simmonds. They developed technology to permit travel between parallel universes.

During the Battle of Canary Wharf, Pete, along with Jake, saved the Doctor from being killed by a Cyberman. Pete used the dimensional transporter to take him and the Doctor to the parallel universe. Pete asked him to help save his world, where the Void opening was causing a rise in temperature.

Pete travelled to the battle, where he saved Rose's Jackie Tyler from two Cybermen, killing them with a Preacher gun. Pete then tried to draw the line between him and Jackie, explaining to her that he was not the same Pete she had married and vice versa; but he ultimately gave in to his emotions and he and Jackie embraced.

A new Jackie
Up in the Void Room of Torchwood Tower, the Doctor decided to name the parallel world Pete's World. Pete teleported Jackie, Rose and himself to the parallel world. However, Rose teleported back to be with the Doctor. The Doctor and Rose opened the Void, to suck all the Cybermen and Daleks in, and would also make travel between their world and Pete's impossible. As the Void was in full force she let go and flew towards the Void opening. Before Rose fell into the Void, Pete teleported back and caught her, saving her life.

Trapped in Pete's world, Pete could only watch as Rose cried. He later drove his new family to Norway, after Rose had a dream in which the Doctor called her there. Pete drove them home again once Rose had said goodbye to the Doctor. (TV: Doomsday)

Later life
Pete and Jackie had a child together, whom they named Tony. Some time later, Pete was tasked with taking care of Tony while Rose and Jackie temporarily travelled back to their Earth to stop the Daleks. After being returned to "Pete's World" by the Doctor, Jackie commented that Pete would have to come and get them from Bad Wolf Bay in Norway, where they had been dropped off by the Tenth Doctor.
