At Cosmomart , the Doctor surrenders to the Sontarans while Cindy lobs a shop dummy head at a soldier . Though she and Gabby are ready to run , the Doctor is adamant that they obey the Sontarans ' commands . The three are led by Commander Sturg to the Sontaran flagship where Cindy realizes the Doctor wanted to be captured . As the Doctor and Alice flee , their pursuer is suddenly killed by a tyrannosaurus rex . Before the apex predator can eat them , they are surrounded by Cyber - Silurians using other dinosaurs as beasts of war . On Karn , the Doctor reveals to the Sisterhood that there is something wrong with time . Though he has tried to reach Gallifrey he cannot breach the transduction barrier nor contact the High Council . As such , he has come to request usage of their " door " . The secret door that the Sisterhood use to reach Gallifrey that no one is supposed to know about . Before Ohila can deny him access , Cybermen enter the chamber . With no alternatives , Ohila leads the Doctor to the door and sends him through , closing it to prevent the Cybermen from following . The Doctor runs to the High Council chamber , calling for his fellow Time Lords to break out the heavy artillery to deal with the crisis . Arriving in the Council chamber however , he is greeted by the sight of Rassilon in command of the Cybermen . Part two . Despite the veritable armada of Cyber Ships surrounding the Capitol , the Twelfth Doctor simply demands to know what the hell Rassilon is doing back on his planet ( as well as where he picked up his new suit ) . Rassilon only scoffs , Gallifrey is now under the jurisdiction of the Gallifreyan Cyber Fleet , the army through which Rassilon will return the Time Lords to their former glory . Rassilon explains that after he was exiled , despite the General ' s worry , he " did " find somewhere to go : the home base of the last remnant of the Cybermen . On Prehistoric Earth , the Eleventh Doctor uses his screwdriver to disrupt the implants on the Cyber - Silurians before he and Alice flee but not back to the TARDIS as Alice thinks . Cyberman technology should not even " exist " in this era and the Doctor is determined to find out what the Cybermen are up to . As the flagship enters the Sontar system , it comes under attack from an unseen hostile . Despite the Tenth Doctor ' s assurance of the hardiness of Sontaran engineering , the craft is forced to make a fiery crash landing . On the surface , he , Cindy and Gabby are brought before Sontaran - Prime , one of the original stock . Though the Prime attempts to put on a brave face , the Doctor can see he is scared . The Cybermen have the Sontarans on the run . In London , Jack Harkness rams the hovercar into the Cyberman base with the quartet scampering into the TARDIS . With his ship back , the Doctor is confident in their chances of victory before the console violently explodes . Sontaran - Prime shows the Doctor the status of the Sontaran Empire which , save Sontar itself , has been completely conquered by the Cybermen . Even the Rutan and Alpha Centauri have fallen . The Doctor realizes the Cybermen are not merely assimilating worlds but actively removing races that pose a threat to galactic conquest . Though the Sontarans are impressed by the Cybermen ' s glorious ruthlessness , the Doctor is dismayed . He had come to the Sontarans for an army to fight the Cybermen . As it turns out , the Sontarans sought out the Doctor for the same reason . The Doctor has seen conflict on an almost unimaginable scale and he will lead the Sontarans to victory over the Cybermen . As the Doctor explains the Cybermen to Alice , the two find a shipyard constructing Arks . Determined , the Doctor realizes the Cybermen objective . Via the Arks , they will seed the galaxy with cyber - technology before most species have had a chance to evolve . Continuing his tale , Rassilon recounts how he marvelled at the Cybermen clinging to life and their purpose but saw an opportunity in their lack of strong leadership . Giving himself over to the Cybermen , Rassilon led them back to Gallifrey with the intent that a Time Lord / Cybermen union will remake the universe . The Doctor is appalled . By giving himself over to the Cyberiad , Rassilon has spat in the face of " Time Lord purity " he has boasted about his whole life . A contingent of Time Lord soldiers then transmat in , shoot the Cybermen and transmat out with the Doctor brining him face - to - face with the General . Part three . Telling her side of the story , the General always knew Rassilon would return to Gallifrey . She never expected him to have allies however , least of all the Cybermen . The invasion force was too powerful for the Time Lord militia leaving the General no choice but to gather what few survivors she could in the Capitol ' s undercity . The base of the resistance is , quite ironically , the Tomb of Rassilon , the only spot on the planet that the Cybermen cannot penetrate . The Doctor doubts the tomb ' s shielding will be useful know that Rassilon will come for him before he asks why a fleet of Battle TARDISes was not sent out . Rassilon was one step head of them affecting something to the Eye of Harmony . As a result , each and every TARDIS is dead . The Doctor suddenly convulses as the Cybermen ' s temporal attacks begin rewriting his timeline . On Prehistoric Earth , the Doctor has finished hacking into the Silurian teleportal that leads him and Alice into a workshop that has been repurposed into a large - scale conversion factory . Accessing the computers , the Doctor finds the Cybermen are receiving quantum data packets from the end of time . The intruder detection systems then come to life and the partially converted Cybermen lumber forth . As the Sontaran army assembles , the Doctor explains to Cindy and Gabby that the Sontarans have been targeted for their cloning technology . With Sontaran technology , the Cybermen could mass - produce an endless supply of Mondasians . And with the Cybermen ' s own world - ship technology , they could take the galaxy in little time . But as Gabby points out , if the Cybermen are going to invade Sontar , then where are they ? Sontaran - Prime scoffs , the Cybermen have evolved beyond simple planetary invasion . As the invaders teleport in , the Doctor realizes that they have not evolved but been given help . Somehow , the Cybermen have acquired Gallifreyan technology . In 2006 , the cloister bell rings as the TARDIS ' s internal systems begin to break down in anticipation of an implosion . The four make a last desperate run for their flyer as the TARDIS interior continues to shrink . On Sontar , the Doctor is so awed by the Cybermen using Time Lord technology that he fails to notice a Cyberman teleporting in from behind before Sontaran - Prime tackles him out of the way , dying in the process . Sturg then destroys the Cyberman before he points out the CyberKings on the horizon . On Prehistoric Earth , the situation has grown dangerous enough that the Eleventh Doctor teleports Alice to safety , instructing her to return to the TARDIS . The Cyber - Silurians continue their advance but the Doctor is unconcerned . The Cybermen cannot assimilate Time Lords . They quickly prove him wrong as one of their number extends their tongue and begins to upgrade him . In 2006 , Jack provides coverfire before he is shot dead . . . by a partially upgraded Rose ! On Gallifrey , the Twelfth Doctor remembers his sixth against the Cybermen in the Matrix , his warrior incarnation a Time War against Cybermen , his predecessor being dragged into the conversion theater by the Cyber - Silurians , an upgraded K9 on his fourth self and his second self on the moonbase . A Time Lady then informs the General that Rassilon has arrived . Confidently , the Doctor opens the tomb and greets the Cyber - President . Part four . Remembering when the Doctor saved Gallifrey , the General is aghast at the Doctor selling the resistance out to Rassilon . The Doctor only laughs , the key to defeating power mad despots is not to hide away in dusty tombs but to get upfront and confront the villains head - on . Rassilon ushers his prisoners into the Panopticon ( now adorned with statues of Rassilon ' s previous selves ) before he activates the Eye of Harmony and leads the two down a lift . Arriving , both the Doctor and the General are shocked at the sight . In London , the Ninth Doctor all but drags Jackie away from the cyber - converted Rose as he swears to avenge her . When he aims his screwdriver at Rose however , a cyber - infection spreads from the device and onto the Doctor ' s hand . Realizing how the Cybermen conquered the planet so fast , the Doctor ushers Jackie into the flyer and explains that the Cybermen have turned the upgrading process into an airborne virus . The Doctor is capable of adjusting the shields to filter out the virus to keep Jackie safe but it will leave her trapped inside with him . On Sontar , the troops are following perfect military protocol but the Doctor highlights " that " is why they are losing . The Cybermen know exactly what the Sontarans will do and are prepared for every eventuality . Cindy proposes ramming a Sontaran scout ship directly into a CyberKing . Sturg disagrees , not only are Cindy and Gabby inexperienced pilots , the attack would be of no tactical value . The Doctor agrees . . . Cindy ' s plan is perfect . The Cybermen will never expect it . The Eleventh Doctor awakens during his conversion . Despite the hopelessness , he takes solace in the fact that Alice is safe . The Cyberiad hacks into his retinas to show him an image of a darkened TARDIS refusing Alice entry . A spark lights within the Doctor as he highlights the error of assimilating him . The Doctor is a tinkerer . Show him a machine and he ' ll reprogram it . Show him a proud warrior race that has had its emotions cut out ? And he ' ll return them tenfold . As the Cyber - Silurians convulse at the horror they have become , Alice flees and the Doctor has a bitter laugh at his victory . On Sontar , the CyberKing fumbles as it tries to intercept Cindy and Gabby ' s pod , giving the Doctor a perfect cover before their craft is simply swatted out of the air . The seeming demise of his friends awakens a fury in the Doctor and he rams his pod directly into the CyberKing ' s head . Exiting the pod , the Doctor wires himself into the dreadnought and sends his rage throughout out the Cyberiad disrupting the invasion . Unbeknownst to him , Cindy and Gabby have survived the crash and witness the act . The Ninth Doctor can feel the nanites swarming his system as he defiantly limps out of the flyer and back towards the TARDIS . Despite his warning , Jackie follows him back into the ship . The Doctor explains the Cybermen will not stop at Earth but if he can stop them here , they won ' t hurt anyone else . With that , he overrides the implosion protocols on the TARDIS to rupture the containment field around the Eye of Harmony , creating an explosion large enough to destroy the Earth completely . The Twelfth Doctor examines the looms Rassilon has wired several Time Lords into to via which he is harvesting their regeneration energy and directing it into the Eye of Harmony . Rassilon defends his actions by reminding the Doctor that he created the Time Lords . They are his to command . As the General is wired into a loom , Rassilon reveals his master plan . The universe is as good as dead and at the moment it finally dies , Rassilon will ignite the accumulated the regenerative energy within the Eye and quite literally regenerate the universe . . . in " his " image . The Cybermen then turn on their ally . There will be a universal regeneration but in " their " image . Part five . Over Rassilon ' s protests , the Cybermen lock both him and the Doctor into looms . The Doctor then remembers everything . His ninth , tenth and eleventh selves fighting the Cybermen , the Fifth Doctor and Peri Skaro while the Seventh Doctor is by an upgraded Ace . Jackie throws herself at the Doctor . He made a promise to Rose that he would protect Earth , he cannot destroy it . The Doctor is profuse in his apologies but Earth is beyond saving and the energy is building up to detonation . . . before it inexplicably vanishes . A closer analysis reveals the energy has been siphoned away before Rose breaks into the TARDIS brandishing her cyber - weapon . On Sontar , the Doctor uses his puppetred CyberKing to quite literally stomp out the invasion force before a Cyber - Ark appears in the sky and commences planetary conversion . On Prehistoric Earth , the exhausted Doctor boasts about his victory before the Cyberiad simply terminates the compromised units . The Cyber - Arks then launch , ready to infect the developing galaxy and the Doctor can howl in despair at his failure . On Gallifrey , Rassilon is unconscious in spite of the Doctor ' s attempts to awaken him . Before the Doctor can be wired into a state of perpetual regeneration , he is approached by the new Cyber - Controller . In spite of everything , the Doctor takes solace that the end of the universe will destroy the Cybermen along with everyone else . The Cyber - Controller disagrees and modifies Rassilon ' s plan . Regeneration does not only bring about a new incarnation , it accelerates the death of the current one . Using Time Lord technology , the Cybermen can apply that principle on a universal scale . As they begin however , Rassilon reads as brain dead . Barely fazed , the Cyber - Controller orders the Doctor plugged in as a replacement . Unseen by all , Rassilon smiles . The Doctor awakens in a virtual recreation of his boyhood barn where he is greeted by Rassilon who masterminded the Doctor being plugged in . The Cybermen have done the impossible and taught Rassilon humility who can do little more than beg the Doctor to win like he always does . The Doctor however is out of options . The Eleventh Doctor tried to change the Cybermen , the Tenth Doctor tried to become them and the Ninth Doctor tried to destroy them . Rassilon reveals all the scenarios targeted at all the Doctor ' s past selves were designed to be too much for him and distract him from the true machinations . The Doctor became a warrior to fight Rassilon ' s war , now Rassilon must become a doctor to help heal the universe . In the real world , the Doctor and Rassilon have been upgraded . With the aperture now open , the Cybermen make ready for the final phase of their plans . Within the simulation , the Doctor and Rassilon glow with regenerative energy . The Doctor declares that they must use their power to regenerate the old universe as opposed to creating a new one . Finally agreeing to bury the hatchet , the two initiate mental contact . As the Cyber - Controller basks in his victory , he is warned that the regenerative energy is flowing backwards through the Eye of Harmony . The Doctor laughs , the Cybermen have been using the Eye of Harmony to affect all their changes to the universe and that same path can be used to undo their plans . Regenerative energy flows through the Eye from Gallifrey to Earth and everywhere in between as the cyber - upgrades are burned off everyone and everything . As the Cyber - Controller explodes from the energy overload , time rewinds and resets . . . Rose Tyler happily reunites with her mother to the Ninth Doctor ' s annoyance , the Tenth Doctor endures Cindy and Gabby ' s indulgent shopping while the Eleventh Doctor and Alice fly in the TARDIS while snacking on prehistoric fruit . Alone in his TARDIS , the Twelfth Doctor wonders if Rassilon remembers the Cybermen invasion . He hopes he does , Rassilon deserves to remember . After all , the Doctor can ' t be alone in " everything " .
