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 . Biography . 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 , Pete met " his " daughter , Rose , whom he began to see a resemblance towards him and Jackie . Later on , 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 EarPod s . 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 once 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 . ( TV : " Doomsday " ) 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 . ( TV : " Journey ' s End " ) Personality . He was once just a normal guy with ideas for how to get rich , often referred to as " daft , little schemes " . ( TV : " Rise of the Cybermen " , " Doomsday " ) By the time of the Doctor ' s visit to their world , things with Pete and Jackie had fallen through , although the two kept this quiet as he felt it would be bad for business to do otherwise . ( TV : " Rise of the Cybermen " ) Although on the surface Pete enjoyed a good working relationship with John Lumic , he was secretly worried about the direction Lumic was heading in and worked as an informant for the Preachers ( although at the time he thought he was broadcasting to the security services ) . Upon meeting them in person following the Cybermen ' s attack on his mansion , he likened them to " Scooby - Doo and his gang " and was not impressed when Ricky admitted he was London ' s most wanted for parking tickets , leaving Pete wondering what he had gotten himself into . ( TV : " The Age of Steel " ) While Pete could be protective of those closest to him and his world , he was , to an extent , indifferent about anything else ; when the Doctor told him sealing the gap between their worlds would mean several million Cybermen would be stuck on the Doctor ' s side , Pete merely said it wasn ' t his problem and he was only concerned what happened to his world . He did , however , have some respect for the Doctor , believing if anyone could defeat the Cybermen and Daleks and seal the gap between their worlds , he could . ( TV : " Doomsday " )
