TARDIS (Time And Relative Dimension(s) In Space)

The TARDIS used from 2005-2010, on display at BBC Television Centre

A TARDIS is a product of the advanced technology of the Time Lords, an extraterrestrial civilisation to which the programme's central character, the Doctor, belongs. A properly maintained and piloted TARDIS can transport its occupants to any point in time and space. The interior of a TARDIS is much larger than its exterior, which can blend in with its surroundings through the ship's "chameleon circuit". In the series, the Doctor pilots an unreliable, obsolete Type 40 TARDIS, whose chameleon circuit is faulty, leaving it locked in the shape of a 1950s-style London police box after a visit to London in 1963. The Doctor's TARDIS was stolen from the Time Lords' home planet, Gallifrey, where it was old, decommissioned and derelict. The unpredictability of the TARDIS's short-range guidance—short relative to the size of the Universe—has often been a plot point in the Doctor's travels.

Although "TARDIS" is a type of craft, rather than a specific one, the Doctor's TARDIS is usually referred to as "the" TARDIS or, in some of the earlier serials, just as "the ship", "the capsule" or even "the police box". (In the two 1960s Dalek films, the craft was referred to as Tardis, without the definite article.)

Doctor Who has become so much a part of British popular culture that not only has the shape of the police box become more immediately associated with the TARDIS than with its real-world inspiration, the word "TARDIS" has been used to describe anything that seems bigger on the inside than on the outside. The name TARDIS is a registered trademark of the British Broadcasting Corporation.

Dalek

Daleks are organisms from the planet Skaro, integrated within a tank-like or robot-like mechanical casing. The resulting creatures are a powerful race bent on universal conquest and domination, utterly without pity, compassion or remorse. Various storylines portray them as having had every emotion removed except hate, leaving them with a desire to purge the Universe of all non-Dalek life. Very occasionally they are shown as experiencing other emotions, including fear, although such occurrences are rare.

Into the unknown......The Eleventh Doctor (Matt Smith)

The Eleventh Doctor is the eleventh and current incarnation of the fictional character known as the Doctor, who appeared on screen in the long-running BBC television science-fiction series Doctor Who beginning in 2010. Matt Smith plays this incarnation, replacing David Tennant's Tenth Doctor in the 2010 episode "The End of Time, Part Two".

Within the series' narrative, the Doctor is a centuries-old alien, a Time Lord from the planet Gallifrey, who travels in time and space in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body but in doing so gains a new physical appearance and with it, a distinct new personality. Smith portrays the eleventh such incarnation.


The Eleventh Doctor first appears in the final minutes of The End of Time (2010). The Tenth Doctor, succumbing to radiation poisoning, sets his TARDIS into orbit around the Earth and begins to regenerate. The regeneration energy causes the TARDIS's windows to shatter and the console room to burst into flames, parts of it even collapsing as a result. On regenerating, the Eleventh Doctor inspects his appearance — briefly panicking about his long hair in the belief that he has regenerated into a girl before innocently confirming otherwise — before realising that the TARDIS is crashing. He clings to the TARDIS console, shouting, "Geronimo!" as the TARDIS falls to Earth.

Speculation about the identity of the Eleventh Doctor began on 28 June 2008; the penultimate episode of the fourth series, "The Stolen Earth", ended as the Doctor was regenerating after being shot by a Dalek's death ray. The lack of a trailer for the second part, "Journey's End", prompted media and public speculation which helped Doctor Who attain the highest position in the weekly ratings in the show's history. The rumoured replacements included Catherine Tate (then playing the Doctor's companion Donna Noble), Robert Carlyle, Jason Statham, Alan Davies and James Nesbitt. The Daily Mail also reported the theories that two Doctors could be created—eventually proven to be correct—and that Tennant's announcement that he would leave in 2009 was a bluff to create a shock regeneration.

Tennant announced at the National Television Awards on 29 October 2008 that he would be stepping down from portraying the Doctor because he felt that the four years he spent portraying the character was enough and to ease the transition from Russell T Davies' showrunning to Steven Moffat's. At the time, BBC News published that Paterson Joseph, who appeared in the Doctor Who episodes "Bad Wolf" and "The Parting of the Ways", was the bookmaker's favourite to succeed Tennant and if chosen would become the first black Doctor, followed by David Morrissey, who would be appearing in the 2008 Christmas special, "The Next Doctor". Other candidates included Sean Pertwee, son of Third Doctor actor Jon Pertwee; Russell Tovey, who portrayed Alonzo Frame in the 2007 Christmas special, "Voyage of the Damned"; and James McAvoy.

Although Steven Moffat expected to pick a middle-aged actor for the new Doctor, at 26 years old, Smith will be the youngest actor to portray the Doctor, three years younger than Peter Davison was at the time he began his role as the fifth Doctor. Smith was one of the first actors to audition for the role, and the production team immediately singled him out based on his performance. Show producers were cautious about casting him because they felt that a 26-year-old could not play the Doctor adequately; BBC Wales Head of Drama Piers Wenger shared the sentiment, but noted that Smith was capable enough to play the role. Smith's casting in the role was revealed during an episode of Doctor Who's companion show Doctor Who Confidential, during which he described the role as "a wonderful privilege and challenge that I hope I will thrive on".

Smith's costume consists of a brown tweed jacket, rose shirt, dark brown braces, bow tie, rolled up navy trousers and black boots. A different coloured variation of this costume – still with the tweed jacket – can be seen in the trailer for Series 5; in addition, the trailer includes footage of the Doctor wearing the tattered suit of the Tenth Doctor in several scenes.

In an interview with Doctor Who Magazine, Steven Moffat revealed that the Eleventh Doctor had an entirely different costume until close to the start of filming. The original look had a piratical feel which Benjamin Cook described as "a little like something Captain Jack Sparrow wears in the Pirates of the Caribbean movies". However Matt Smith was unhappy with the costume as he felt it reflected how someone else would dress the Doctor, rather than how the Doctor would dress himself. The eventual costume, in particular the bow-tie, was influenced by Patrick Troughton's Second Doctor, after Matt Smith fell in love with the Troughton story The Tomb of the Cybermen.

The TENTH Doctor (David Tennant)

The Tenth Doctor is the tenth incarnation of the fictional character known as the Doctor seen on screen in the long-running BBC television science-fiction series Doctor Who. He is played by David Tennant, who replaced Christopher Eccleston's Ninth Doctor in the 2005 series finale, "The Parting of the Ways". Tennant appears in three series, as well as eight specials. As with previous incarnations of the Doctor, the character has also appeared in other Doctor Who multimedia.

In the series' narrative, the Doctor is a centuries-old Time Lord alien from the planet Gallifrey who travels in time in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body; in doing so, his physical appearance and personality change. Tennant portrays the tenth such incarnation. His companions include Rose Tyler (Billie Piper), who was already travelling with his predecessor; Martha Jones (Freema Agyeman) and Donna Noble (Catherine Tate), but he eventually parts ways with them all by the end of the 2008 series finale, "Journey's End". Wilfred Mott (Bernard Cribbins) briefly serves as his companion during the events of the 2009 two-part special "The End of Time".

During an acceptance speech of a 2008 National Television Award for his role as the Tenth Doctor, David Tennant announced that he would not be returning as the intrepid Time Lord for the fifth series, scheduled to be broadcast in 2010. He made his final appearance as the Doctor in The End of Time.

In 2009, Doctor Who Magazine readers voted the Tenth Doctor as Number One in Issue 414's Favorite Doctor poll, winning 25.64% of the vote, beating the Fourth Doctor (Tom Baker) who came in at number 2 with 24.73% of recorded votes.

After the successful premiere of "Rose" and announcement of a second series being commissioned by the BBC, the story broke that Christopher Eccleston, who played the Ninth Doctor, would not be returning for the second series. On 16 April 2005, the BBC announced that David Tennant had been selected for the role of the Tenth Doctor. His first appearance in the series was for 20 seconds following the Ninth Doctor's regeneration at the end of "The Parting of the Ways". His first full episode as the Doctor, barring an appearance in a "mini-episode" during the 2005 Children in Need show, was the 2005 Christmas Special, "The Christmas Invasion". He then appeared in the 2006 series, the second seasonal episode, the 2007 series, the third Christmas special, and the 2008 series. Rather than a traditional series run, 2009 features a series of five specials and a series of animated shorts, all starring Tennant as the Tenth Doctor; he also guest-starred in a two-episode serial of The Sarah Jane Adventures spin-off in that year.

In 2006, readers of Doctor Who Magazine voted Tennant's Doctor "Best Doctor" over perennial favourite Tom Baker.

A thirteen-part animated adventure, The Infinite Quest, featuring the Tenth Doctor and companion Martha Jones (voiced by David Tennant and Freema Agyeman) premiered on Totally Doctor Who on 2 April 2007; the last segment of The Infinite Quest was shown with all previous episodes as an entire Doctor Who episode on 30 June 2007. The Tenth Doctor also appeared in a second animated serial, Dreamland, aired on CBBC in Autumn 2009.

While the previous Doctor was never explicitly referred to as the Ninth on-screen, the exact number of incarnations thus far was confirmed in-series by sketches of the ten Doctors to date in the sketchbook A Journal of Impossible Things that appeared in 2007's "Human Nature" (although only five incarnations are visible on-screen, the other five also appear on a two-page scan seen on the BBC's tie-in website). In "School Reunion", the Tenth Doctor commented to Sarah Jane Smith that he had regenerated half a dozen times since they had last met; Sarah last saw the Doctor at the end of the Fourth Doctor serial The Hand of Fear (in the anniversary special "The Five Doctors" (1983), she is paired up with the Third Doctor, and also meets the Fifth Doctor, Second Doctor, and First Doctor). Off-screen, on the DVD commentary for "The Parting of the Ways", Julie Gardner states after the regeneration sequence, "Tennant is Ten!". For the soundtrack of "The Christmas Invasion", a specially commissioned piece played during the sequence in which the Doctor chooses his new outfit was titled "Song for Ten". The BBC's official website refers to Tennant's Doctor as the "Tenth Doctor", as do all promotional materials for the show, such as trading cards and action figures.


The Ninth Doctor regenerates into the Tenth Doctor due to cellular damage caused by absorbing the energies of the time vortex at the climax of "The Parting of the Ways". In the untitled Children in Need mini-episode, the Doctor initially exhibits stable behaviour as he introduces his new form to Rose Tyler, showing particular interest in his appearance, but soon begins acting erratically and says that his regeneration has "gone wrong". He remains in a delirious or comatose state through most of the events of "The Christmas Invasion" until his regeneration is settled through absorbing the free radicals and tannin from some hot tea that had dripped onto a power source inside the TARDIS. He then saves the Earth from invasion by killing the leader of the alien Sycorax using a satsuma when he refuses to leave peacefully ("No second chances; I'm that sort of a man", he remarks). The Doctor's right hand is severed in the fight, although he regenerates a new one since his regeneration cycle was not fully completed.

The Tenth Doctor and Rose go on to meet Queen Victoria, saving her from a werewolf which resulted in not only the Doctor's knighting as "Sir Doctor of TARDIS" and banishment from the British Empire, but also resulted in the creation of the Torchwood Institute, an Earth organization dedicated to policing supernatural and alien affairs. After being reunited with his previous incarnation's companion, Sarah Jane Smith, the Doctor, Rose, and Mickey Smith end up in an alternate universe where the Cybermen originate on Earth. After stopping them, the Doctor leaves Mickey behind at his request. During the 2-part event of "The Impossible Planet" and "The Satan Pit", the Doctor encounters the Torchwood Archive as they unknowingly awakened the Beast, who spoke of Rose's death to her shock as the Doctor assures her that it was only words. But the Beast's prophecy comes true when the Doctor eventually returns to present-day Earth, his TARDIS is stolen by the Torchwood Institute, who are manipulated by the Cybermen into creating a link to their universe through the Void, which inadvertently frees the Dalek Empire from the Time War as well. The Torchwood Institute forms a truce with the Cybermen until the Daleks are returned to the Void, at the cost of Torchwood's main base, the scattering of the Cybermen through time and space, and Rose, believed dead to the general public, ending up at the alternate universe with her mother and Mickey.

Immediately after the loss of Rose, who was in love with him, the Doctor meets Donna Noble, a bride drawn to the TARDIS during her wedding by a poisonous energy administered to her by the Racnoss, a race of spider aliens that had been hibernating in the Earth's core and needed to use Donna as a key to release themselves. The Doctor cures Donna and murders the Racnoss Queen and her brood, planning to die with them until Donna saves him. The Doctor offers Donna companionship, which she refuses but she suggests the Doctor finds someone who can "stop [him] sometimes". The Doctor later saves Martha Jones from an alien vampire pursued by the Judoon, and brings her on his various adventures, one of which has him meet the Face of Boe before his death and hearing his final worlds, "You Are Not Alone". In the far, far future, near the Heat death of the universe, after the TARDIS attempted to shake off Captain Jack Harkness, the Doctor learns the meaning behind the Face of Boe's final worlds when he and Martha inadvertently free the Master from a Chameleon Arch. The Master immediately steals the TARDIS and regenerates, returning to Earth in 2006 and becoming Prime Minister of the United Kingdom. When the Doctor and Martha return, hitching a ride on Jack's Vortex Manipulator, the Master captures the Doctor and Jack, using them to enslave the human race. Martha escapes capture and attempts to undermine the Master. With Martha's help, the Doctor eventually defeats the Master and reverses the year during which he nearly destroyed the universe. After the universe is safe, the Master is shot and dies in the Doctor's arms.

After Martha and Jack's departure in the aftermath of the Master's death, the Doctor finds himself on a replica of the Titanic and keeps it from crashing onto London on Christmas Day. Soon after, the Doctor once more crosses paths with Donna, who accepts his offer and becomes his companion. Throughout their journey to places like Pompeii and the Planet of the Ood, the Doctor and Donna receive cryptic mentions of their future as well as equally mysterious appearances of Rose. After helping Martha and UNIT against the Sontarans, the TARDIS takes the Doctor, Donna, and a confused Martha to the planet Messaline in an unknown time period where the armed human colonists' forceful extrapolation of the Doctor's DNA results in the birth of Jenny, whom the Doctor eventually accepts as his 'daughter,' only to be separated from her by the end of the episode after he believes her to have died, not knowing that she later returned to life once he left.

In the aftermath of "Turn Left" and as The Stolen Earth begins, the Doctor is warned by Rose through Donna that the world is endangered. Finding the Earth gone, the Doctor contacts the Shadow Proclamation, learning that Earth is the latest of a series of planets that vanished. With the aid of the Doctor's former companions Captain Jack, Martha and Sarah Jane Smith, the Doctor pinpoints their location and learns that Davros is the cause of the planets' disappearance. The Doctor arrives on Earth where Rose is waiting for him, however before they are reunited, the Doctor is mortally shot by a Dalek, evoking his regeneration which he manages to redirect towards his previously severed hand that is connected to the TARDIS, keeping the Doctor in the same form. That action led to Donna inadvertently causing a "human biological metacrisis" by touching the severed hand, causing her to manifest into a Time Lord/human hybrid version of the Tenth Doctor to be created as well as Donna's eventual transformation into the predicted Doctor Donna that led to the Daleks' defeat and the worlds returned to their rightful places. After saying goodbye to his former companions, the Doctor is forced to erase Donna's memories when the Time Lord energy within her starts to consume her and leaves her behind as he departs in the TARDIS by himself. In the following special episode, "Music of the Spheres", his musical talent is revealed, when he has taken his mind off his loneliness by composing an "Ode to the Universe".

In "Planet of the Dead", after returning stranded humans from San Helios, the Doctor is told of a premonition: "Your song is ending, sir. It is returning, it is returning through the dark. And then Doctor... oh, but then...he will knock four times", an event which will precede his death. It starts to become a reality during "The End of Time", when the Master is resurrected and rewrites humanity's genetic makeup in his own image, as an unwitting part of a plan designed to enable the Time Lords to escape their fate at the end of the Time War. After the Master and the Time Lords are stopped and the planet is safe, the Doctor finds his companion, Wilfred Mott, locked in a containment chamber in danger of imminent fatal contamination. Wilf knocks four times to alert the Doctor to his situation. Though raging against the universe for his fate, the Doctor nevertheless enters the cubicle to save Wilf, causing himself to suffer a lethal dose of radiation poisoning. The Doctor spends the remainder of his life paying final visits to his past companions, his last being Rose Tyler in a time before she met his previous incarnation. Dying a slow death, the Doctor sets a new course in the TARDIS before he begins to regenerate, his last words being "I don't want to go". With a massive release of energy that cripples his ship, he regenerates into the Eleventh Doctor.

The Ninth Doctor (Christopher Eccleston)

The Ninth Doctor is the ninth official incarnation of the fictional character known as the Doctor, in the long-running BBC television science-fiction series Doctor Who. He is played by Christopher Eccleston.

"Unofficial" Ninth Doctors include the Ninth Doctor played by Rowan Atkinson in the charity parody Doctor Who and the Curse of Fatal Death and the Ninth Doctor voiced by Richard E. Grant in the animated webcast Scream of the Shalka (to avoid confusion with Eccleston's incarnation Grant's Doctor is referred to as the Shalka Doctor by fans). This article is about the official Ninth Doctor, whose tenure as the Doctor made up series 1 of the revived programme in 2005.

Within the series' narrative, the Doctor is a centuries-old alien, a Time Lord from the planet Gallifrey, who travels in time in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body but in doing so gains a new physical appearance and with it, a distinct new personality. Eccleston portrays the ninth such incarnation, a brooding and melancholic war survivor after a Time War in which he wiped out both his race and the enemy Daleks. His first companion is Rose (Billie Piper), whom he plucks from obscurity on the planet Earth and to whom he grows increasingly attached. Eccleston's Doctor also travels briefly with unruly boy-genius Adam (Bruno Langley) and with 51st century con man and former 'Time Agent' Captain Jack Harkness (John Barrowman).

The original Doctor Who television series ceased production in 1989 with the Seventh Doctor. The Eighth Doctor, Paul McGann appeared in the role just once on screen in the Doctor Who television movie in 1996. The appearance of the Ninth Doctor marked the regular return of the character to television screens after nearly sixteen years, and as a result for many young fans and new viewers he was the first Doctor they had ever seen. He was introduced without any information on his recent past; though it is implied in "Rose" that he may have recently regenerated, the exact circumstances of that change, or what caused it, are unknown.

The Eighth Doctor (Paul McGann)

The Eighth Doctor is a fictional character, the eighth incarnation of the Doctor seen on screen in the long-running BBC television science-fiction series Doctor Who. He was portrayed by Paul McGann. Though he appeared in only one TV feature, his adventures are extensively portrayed in other media.

Within the series' narrative, the Doctor is a centuries-old alien, a Time Lord from the planet Gallifrey, who travels in time in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body but in doing so gains a new physical appearance and with it, a distinct new personality. McGann portrays the eighth such incarnation, a passionate, enthusiastic and eccentric character. His only companion in the television movie is Grace Holloway (Daphne Ashbrook), a medical doctor whose surgery is responsible for triggering his regeneration. In the continued adventures of the character depicted in audio dramas, novels and comic books he travels alongside numerous other companions, including self styled "Edwardian Adventuress" Charley, the alien Destrii and present-day humans Lucie and Sam.

The Eighth Doctor is the first since the original incarnation (portrayed by the late William Hartnell) not to have his face appear in the opening title sequence. This trend would continue throughout the revived series with the Ninth and Tenth Doctors.

The Eighth Doctor made his first and only television appearance in the 1996 Doctor Who television movie, the first time the Doctor had returned to television screens since the end of the original series in 1989. Intended as a backdoor pilot for a new television series on the Fox Network, the movie was inadequately marketed and advertised (and in some markets even pre-empted by televised sporting events), ultimately leading to poor US ratings. In the UK, however, it was received well, attracting over 9 million viewers and generally positive reviews. It was also generally well received in Australia.

Although the movie failed to spark a new television series, the Eighth Doctor's adventures continued in various licensed spin-off media, notably BBC Books' Eighth Doctor Adventures novels, audio plays from Big Finish Productions, and the Doctor Who Magazine comic strip. As these stories spanned the nine years between 1996 and the debut of the new television series in 2005, some consider the Eighth Doctor one of the longest-serving of the Doctors. He is unarguably the longest-serving Doctor in the Doctor Who Magazine comic strip. In the wake of the positive reaction to the revived television series in 2005, several of the Eighth Doctor's Big Finish audio dramas were also broadcast on BBC7 radio in an edited form. The trailers for these broadcasts explained that these adventures took place before the destruction of Gallifrey as described in the revived TV series. In 2007, the BBC7 aired a new series of Eighth Doctor audio adventures, created specifically for radio broadcast. Paul McGann has continued to portray the Eighth Doctor in the various audio spinoffs.

The canonicity of the spin-off media with respect to the television series and to each other is open to interpretation (the "Beginner's Guide to Doctor Who" on the BBC's classic Doctor Who website suggests this may be due to the Time War). It has been suggested that the Eighth Doctor's adventures in three different forms (novels, audio, and comics) take place in three separate continuities. The discontinuities were made explicit in the audio drama Zagreus. In response, it has become increasingly common to consider the three ranges separately. The final Eighth Doctor Adventures novel, The Gallifrey Chronicles, obliquely references this split in timelines, even suggesting that the split results in the three alternative forms of the Ninth Doctor (a reference to the fact three different versions of the incarnation have appeared in various media). Even so, all matters of canonicity remain typically unclear.

Despite the fact the Eighth Doctor appeared on television only once, he is the most prolific of all the Doctors (to date) in terms of number of individual stories published in novel, novella, short story and audio form. In 2007, the Eighth Doctor finally made a second appearance (of sorts) within the television series' continuity. In the episode "Human Nature" he appears on-screen as a sketch (alongside other incarnations) in the book A Journal of Impossible Things by John Smith. In 2008 he appeared again as a brief image in "The Next Doctor" along with every other incarnation up to that time.

The Seventh Doctor (Sylvester McCoy)

The Seventh Doctor is a fictional character, the seventh incarnation of the Doctor seen on screen in the long-running BBC television science-fiction series Doctor Who. He was portrayed by the actor Sylvester McCoy.

Within the series' narrative, the Doctor is a centuries-old Time Lord alien from the planet Gallifrey who travels in time and space in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body; in doing so, his physical appearance and personality change. McCoy portrays the seventh such incarnation, a whimsical, thoughtful character who quickly becomes more layered, secretive and manipulative. His first companion was Melanie Bush (Bonnie Langford), a computer programmer who travelled with his previous self, and who is soon succeeded by troubled teenager and explosives expert Ace (Sophie Aldred), who becomes his protégé.

In his first season, the Seventh Doctor started out as a comical character, mixing his metaphors ("Time and tide melt the snowman," for example), playing the spoons, and making pratfalls, but soon started to develop a darker nature and raised the profound question of who the Doctor actually is. The Seventh Doctor era is noted for the cancellation of Doctor Who after 26 years. It is also noted for the Virgin New Adventures, a range of original novels published from 1992 to 1997, taking the series on beyond the television serials.

In 1990, readers of Doctor Who Magazine voted McCoy's Doctor "Best Doctor", over perennial favourite Tom Baker.

The Seventh Doctor's final appearance on television was in the 1996 Doctor Who television movie, where he regenerated into the Eighth Doctor, played by Paul McGann. A sketch of him is later seen in John Smith's A Journal of Impossible Things in the new series 2007 episode "Human Nature". A brief holographic clip of the Seventh Doctor appears in "The Next Doctor".

When the TARDIS was attacked by the Rani, the Sixth Doctor was injured and forced to regenerate. After a brief period of post-regenerative confusion and amnesia (chemically induced by the Rani), the Seventh Doctor thwarted the Rani's plans, and rejoined his companion Mel for whimsical adventures in an odd tower block and a Welsh holiday camp in the 1950s.

On the planet Svartos, Mel decided to leave the Doctor's company for that of intergalactic rogue Sabalom Glitz. Also at this time, the Doctor was joined by time-stranded teenager Ace. Although he did not mention it at the time, the Doctor soon recognised that an old enemy from a past adventure, the ancient entity known as Fenric, was responsible for the Time Storm which transported Ace from 1980s Perivale to Svartos in the distant future. Growing more secretive and driven from this point on, the Doctor took Ace under his wing and began teaching her about the universe, all the while keeping an eye out for Fenric's plot. The Doctor began taking a more scheming and proactive approach to defeating evil, using the Gallifreyan stellar manipulator named the Hand of Omega as part of an elaborate trap for the Daleks which resulted in the destruction of their home planet, Skaro. Soon afterwards, the Doctor used a similar tactic and another Time Lord relic to destroy a Cyberman fleet. He engineered the fall of the oppressive government of a future human colony in a single night and encountered the Gods of Ragnarok at a circus on the planet Segonax, whom he had apparently fought throughout time. Later, he was reunited with his old friend, Brigadier Lethbridge-Stewart while battling the forces of an alternate dimension on Earth.

The Seventh Doctor's manipulations were not reserved for his enemies. With the goal of helping Ace confront her past, he took her to a Victorian house in her home town of Perivale in 1883 which she had burned down in 1983. Eventually, the Doctor confronted and defeated Fenric at a British naval base during World War II, revealing Fenric's part in Ace's history. The Doctor continued to act as Ace's mentor, returning her to Perivale; however, she chose to continue travelling with him. The circumstances of her parting from the Doctor were not shown on television.

Near the end of his incarnation, the Seventh Doctor was given the responsibility of transporting the remains of his former enemy the Master from Skaro to Gallifrey. This proved to be a huge mistake: despite having a limited physical form, the Master was able to take control of the Doctor's TARDIS and cause it to land in 1999 San Francisco, where the Doctor was shot in the middle of a gang shoot-out. He was taken to a hospital, where surgeons removed the bullets but mistook the Doctor's double heartbeat for fibrillation; their attempt to save his life instead caused the Doctor to "die" with one last shocking scream. Perhaps due to the anesthesia, the Doctor did not regenerate immediately after death (unlike all previous occasions); he finally did so several hours later, while lying in the hospital's morgue.

In Time and the Rani the Seventh Doctor gives his age soon after his regeneration as "exactly" 953 years, indicating that some two centuries of subjective time has passed since his fourth incarnation was revealed to be 759 in The Ribos Operation, and approximately half-a-century since Revelation of the Daleks in which the Sixth Doctor stated he was 900 years old. The later revival of the series, however, has contradicted the age given by the Seventh Doctor (and the Sixth) by establishing the Ninth Doctor as 900 years old, with the Tenth Doctor stating his exact age as 903 in Voyage of the Damned and 906 in The End of Time.
