A Biography of the Doctor

The Doctor and Rose arrive on the polar region of the planet Serac. They are captured by Sontarans, operating from the mining rig The Betrothal of Sontar. It's commanding officer, Colonel Snathe, is obsessed with a legendary super-weapon called Thanatos, which he believes is located on the planet.

He forces the Doctor to help him search, and finds it. The weapon is sentient, and decides to destroy the planet of Sontar. It is stopped when Snathe's first officer, Commander Lerox, risks his life to protect Rose Tyler and the Doctor persuades it that there is still hope for the Sontarans. Snathe dies whilst escaping.

The TARDIS travels to New Earth, galaxy M87 in the year five billion and twenty three. The Doctor gets a message from the Face of Boe on his Psychic Paper telling him to go to Ward 26 of the nearby hospital. Rose meets Cassandra, who she believed to have died aboard Platform One (The End of the World).

Cassandra possesses Rose's body and manipulates the Doctor into helping her find out that the Sisters of Plenitude who run the hospital are curing diseases by growing infected human lab rats. The Doctor manages to cure the lab rats and forces Cassandra to leave Rose's body. Cassandra travels into the body of one of her cloned servants, and the Doctor allows her one last wish - to travel back to a party in her youth and tell her younger self that she looks beautiful.

Rose says she fancies an ice cream, so the Doctor takes her to Milan, 1925. Whilst they are there, the city is consumed by a time wave, and transformed into a lifeless futurist city, with only the Doctor, Rose, local girl Altea, and a time-displaced Roman soldier left. They travel back to the soldier's native 3rd Century. They encounter Altea's futurist boyfriend, who has teamed up with extra-dimensional aliens called the Hajor to impose his vision on the world. They are defeated when the soldier – who is also connected to the Hajor – banishes them to their own realm.

The Doctor intends to take Rose to a concert in 1979, but the TARDIS instead lands in 19th Century Scotland. They meet Queen Victoria and her retinue, staying with them overnight at Torchwood House, where her late husband often spent time. The local werewolf legends turn out to be true – there is a werewolf (actually an alien possessing human bodies) in the cellar, which escapes.

It turns out that Prince Albert and the father of the house's owner planned a trap for the wolf in the house's observatory. The telescope, combined with the Koh-i-noor diamond, can focus the moon's light strongly enough to kill it. After the werewolf is killed, Victoria gives the Doctor a knighthood (Sir Doctor of Tardis) and Rose a Damehood (Dame Rose of the Powell Estate) before banishing them both from the British Empire.

The Doctor invites a new companion onto the TARDIS. He links his new companion's remote control to the sonic screwdriver, enhancing its abilities. They monitor a welsh family at Christmas, noticing that the mother has been replaced by the Graske. They then track the Graske back by about 120 years to 1883.

The new companion infiltrates the Graske's base to free the people who have been replaced. They companion is spotted, and a Graske opens fire. The blast ricochets around the storage area, damaging the controls and freeing a Raxicoricofallapatorian. The Raxicoricofallapatorian breaks out and chases the Graske. The companion takes the opportunity to activate the controls choosing either to place the planet in stasis or to return the original people to their native time and place, replacing their duplicates.

The Doctor then returns his new companion back home before travelling back to pick up Rose. This adventure is caught in a time loop, and the new companion makes a different set of choices every time.

The TARDIS lands on an abandoned spaceship about 3,000 years in the future. It has an 18th Century French fireplace - the other side of which is in 18th Century France. The Doctor talks to Reinette - the little girl whose fireplace it is. He travels to France via this time window, arriving months later. He discovers something hiding under her bed - it wants Reinette, but she is "not yet complete" and flees back into the spaceship. He follows the robot back, and discovers that it is made of clockwork.

He finds Returning to Reinette, he finds her grown up and discovers that she is Madame du Pompadour. He then discovers another time window to her life, just after she met King Louis for the first time. It turns out that the clockwork robots were trying to repair their ship but didn't have the parts, so used the crew instead. It and its fellows are after one last part, and want Madame Pompadour's brain. They believe that her brain will only be compatible at the age of 37, when she will be the same age as the ship.

The Doctor returns to the ship well after the robot has run back there to find that the robots have opened a portal to a time when Reinette is 37. Rose finds a window when she is 32 and warns her of the danger. The Doctor finds the window the robots have gone through and crashes through it, disabling all the time windows. He then convinces the robots that their plan will not work without a way back, and they shut themselves down.

Reinette then shows the Doctor that she has moved the original fireplace to Versailles. He realises that it broke before he destroyed the time windows and that he can repair it to get back to the ship. He does so, checks up on Rose and Mickey, and then goes back to Reinette - who he promised to take to the stars. However, he arrives back in Versailles just as her coffin is leaving the palace, and the King gives him a note from Reinette.

The Doctor destroys the Cybermen surrounding them by using the power cell from the TARDIS. They escape in Ricky's group's van, and discover that Pete is the group's secret information source, Gemini. Arriving in London, they discover that Lumic has used the earpieces to control London's population, herding them into a factory at Battersea which is creating Cybermen. Ricky is killed by the Cybermen.

They try to sneak in in various different ways. The Doctor discovers that these alternative Cybermen can be defeated by shutting down their emotional inhibitor chip before being captured and taken to the control centre. Pete and Rose also end up there, having discovered that Jackie has been "upgraded".

Mickey finds a way to spy on Cyber-Control. The Doctor realises that Mickey is watching, and casually mentions the location of the code for the emotional inhibitor and to send it to Rose's phone. She gets the message, chucks the phone to the Doctor, and he inserts it into a conveniently-located piece of equipment which sends the code to every Cyberman. The Cybermen all go mad and self-destruct, taking the factory with them.

Mickey decides to stay behind on the alternative Earth, help shut down the Cyber-factories, and look after his gran, even though the Doctor says that once the TARDIS leaves, it will be impossible to return.

The TARDIS lands in a santuary base, though it is clearly reluctant to do so. The base contains writing that the TARDIS can't translate – meaning that it is impossibly old. The base is on a planet that is orbiting a black hole, and the crew consist of humans and Ood. The Ood apparently offer themselves as slaves and want to have orders. They are drilling into the heart of the planet to extract a power source that is generating an impossibly powerful gravitational field.

The Oods' translators start saying odd things, and that "he" is awake. Shortly afterwards the drill reaches the centre, and the Doctor volunteers to investigate with one of the crew. It turns out that there are the ruins of a civilisation. On the base, Toby, the base's archaeologist, reveals that he has been possessed by the being entombed there (the Beast). He telepathically takes control of the Ood. At the stame time, the planet nudges out of orbit and starts falling towards the black hole.

The Doctor visits Elton Pope's house, trying to defeat an Elemental Shade who had escaped from the Howling Halls. He stopped it, but Elton's mother died before he could do so.

The Doctor and Rose are fighting a Hoix on contemporary Earth when Elton barges in searching for the Doctor. The Doctor and Rose defeat it, stopping it from attacking Elton in the process. He thinks that he recognises Elton.

The Doctor tracks down Elton, and an Absorbalof from Clom (the twin planet of Raxacoracofallapatorius) who has been trying to absorb Elton. He hints that the people who have been absorbed can fight the Absorbalof. They do so - pulling its body apart, and Elton snatches and breaks a cane it has been carrying, as one of them suggests. The cane contained a limitation field which kept its body together.

The TARDIS arrives on the Powell estate to find that ghosts are appearing, walking around, and fading at fairly precise intervals. The Doctor theorises that something is pressing itself into this reality. He sets up some equipment to monitor the ghost shifts and work out where the ghosts are coming from. He pinpoints the machinery which is causing the shifts. It turns out to be Torchwood, an organisation the Doctor was ignorant of. He is given a grand tour, showing that they develop technology developed from alien material on Earth. They were created by Queen Victoria after Tooth and Claw to protect Britain and use alien technology "for the good of the British Empire".

One of Torchwood's artefacts is a "void ship" - a vessel that exists outside of time and space. It came through a breach in space-time, and Torchwood have been exacerbating the hole - causing the ghost shifts - in order to get energy from it. Rose sneaks in to find Mickey posing as a lab assistant. The systems are then overriden by staff wearing earpods like the ones from the parallel world in Rise of the Cybermen/The Age of Steel. The ghost shift is turned on full, the voidship becomes solid, and the ghosts materialise across the world, becoming Cybus Cybermen, who are invading Earth. At the same time, the voidship opens, revealing four Daleks and a device they call the Genesis Ark.
