Doctor (Doctor Who) Totally Explained

Everything about Doctor Doctor Who totally explained

The Doctor is the central character in the long-running BBC television science-fiction series Doctor Who, and also features in a vast range of spin-off novels, audio dramas and comic strips connected to the series.
To date, ten actors have officially played the role in the television series (including the 1996 television film), with these changes being explained by his ability to regenerate. Several other actors have played the character on stage and film, in audio dramas, and in occasional special episodes of the series. David Tennant currently portrays the tenth incarnation of the Doctor.

Background

The Doctor is a Time Lord, an extraterrestrial scientist from the planet Gallifrey, who wanders time and space in an internally vast time machine called the TARDIS — Time And Relative Dimension(s) In Space — an acronym the Doctor's granddaughter, Susan, claims to have invented. Although the TARDIS once had the ability to disguise itself according to its environment, after landing in 1963 London its facade became stuck in the form of a British police box because of a malfunctioning chameleon circuit. It has remained in that shape ever since. Over the course of the series the Doctor occasionally attempts to fix the circuit, most notably in Logopolis and Attack of the Cybermen (in the latter turning the TARDIS exterior into a pipe organ, among other incongruous shapes), but eventually gives up the effort out of fondness for the police box shape. The discrepancy between the small exterior of the ship and its vast interior is explained by its dimensionally transcendental nature, whereby the ship's interior and exterior dimensions exist independently of each other.
   Little is known about the Doctor's childhood. In "The Empty Child" the Doctor claimed he knows "what it's like to be the only child left out in the cold". Later, during "The Girl in the Fireplace", Madame de Pompadour "saw" memories of his childhood during a telepathic session between the two and commented that it was "so lonely". However, when asked if he's a brother in "Smith and Jones", the Doctor simply replied "not any more". In the same episode, he mentioned "playing with Röntgen blocks in the nursery." In The Time Monster, the Doctor says he grew up in a house on the side of a mountain, and talks about a hermit who lived under a tree behind the house and inspired the Doctor when he was depressed. In "The Sound of Drums" (2007), the Doctor describes a Time Lord Academy initiation ceremony where, at the age of eight, Time Lord children are made to look into the Untempered Schism, a gap in space and time where they could view the time vortex. Some are inspired, some go mad (as he suggests happened to his nemesis the Master), and some run away. When asked what he did, he replies, "Oh, one of the ones that ran away - I've never stopped!"
   References to the Doctor's family are rare in the series. During the first two seasons he travelled with his granddaughter, Susan Foreman, and as noted above he apparently once had a brother. During his second incarnation when asked about his family, the Doctor says his memories of them are still alive (The Tomb of the Cybermen) but whether that means they're deceased is unknown. In The Curse of Fenric, when asked if he's any family, the Seventh Doctor replies that he doesn't know, indirectly hinting that an unspecified fate may have befallen them. In "Fear Her" the Tenth Doctor mentions to Rose that he was once a father, but then quickly changes the subject. He mentions his father in the 1996 Doctor Who telefilm, where he also indicates his mother was human (see "Continuity curiosities" below). In "The Doctor's Daughter", the Doctor had his genetic information stolen and used to create a female soldier and comes to refer to the result, a young woman named Jenny (played by Georgia Moffett, real world daughter of Peter Davison), as his daughter (she in turn knows him as her father).
   The Doctor explores the universe at random, using his extensive knowledge of science, technology and history (from his perspective) to avert whatever crises he encounters. The imprecise nature of his travels is initially attributed to the age and unreliability of the TARDIS's navigation system. However, after his trial and restriction to late twentieth century Earth, he demonstrates the ability to reach a destination of his own choosing more often than not. The Doctor generally travels with one or more companions. Most of these make a conscious decision to travel with him, but others, especially early in the series, are accidental passengers.
   Although Time Lords resemble humans, their physiology differs in some key respects. For example, like other members of his race, the Doctor has two hearts (binary vascular system), a "respiratory bypass system" that allows him to go without air for some while, an internal body temperature of 15–16 degrees Celsius (60 degrees Fahrenheit) and he occasionally exhibits a super-human level of stamina. Additionally, he's shown a resistance to temporal effects and has demonstrated a telepathic ability, albeit to a limited degree. In "The Fires of Pompeii" the Doctor reveals that he's able to perceive the fabric of time, discerning "fixed points" and "points in flux". The Doctor also exhibits some weaknesses uncommon to humans. For example, in The Mind of Evil (1971) he claimed that a tablet of aspirin could kill him.
   In his final serial, the Second Doctor states that Time Lords can live forever, "barring accidents." When "accidents" do occur, Time Lords can usually regenerate into new bodies, resulting in extremely long life-spans.

In the beginning

The character of the Doctor was created by the BBC's Head of Drama Sydney Newman, the driving force behind the creation of Doctor Who itself. The first format document for the series that was to become Doctor Who — then provisionally titled The Troubleshooters — was written up in March 1963 by C. E. Webber, a BBC staff writer who had been brought in to help develop the project. Webber's document contained a main character described as "The maturer man, 35–40, with some 'character twist'." However, Newman wasn't keen on this idea and — along with several other changes to Webber's initial format — created an alternative lead character named "Dr Who": a crotchety older man piloting a stolen time machine, on the run from his own far future world. No written record of Newman's conveyance of these ideas — believed to have taken place in April 1963 — exists, and the character of "Dr Who" first begins appearing in existing documentation from May of that year.
The character was first portrayed by William Hartnell in 1963, who played him as the irascible, grandfatherly figure originally conceived by Newman. When, after three years, Hartnell left the series due to ill health, the role was handed over to respected character actor Patrick Troughton. To date, official television productions have depicted ten distinct incarnations of the Doctor (due to Hartnell's death in 1975, actor Richard Hurndall substituted in his role as the First Doctor in 1983's The Five Doctors, resulting in a technical total of eleven actors). Of those, the longest-lasting and perhaps the most recognisable incarnation is the Fourth Doctor, as played by Tom Baker. Currently, the Tenth Doctor is portrayed by David Tennant.
At the series' beginning, nothing at all is known of the Doctor: not even his name (the actual form of which remains a mystery). In the very first serial, An Unearthly Child, two teachers from Coal Hill School in London, Barbara Wright and Ian Chesterton, become intrigued by one of their students, Susan Foreman, who exhibits high intelligence and unusually advanced knowledge. Trailing her to a junkyard at 76 Totter's Lane, they encounter a strange old man and hear Susan's voice coming from inside what appears to be a police box. Pushing their way inside, the two find that the exterior is actually camouflage for the dimensionally transcendental interior of the TARDIS. The old man, whom Susan calls "Grandfather" but who identifies himself as "the Doctor", subsequently kidnaps Barbara and Ian to prevent them from telling anyone about the existence of the ship, taking them on an adventure in time and space.

Becoming "involved"

The Doctor is an adventurer and scientist with a strong moral sense. He usually solves problems with his wits rather than with force, and is more likely to wield a sonic screwdriver than a gun; although he's been seen to use weapons as a last resort.
   As a time traveller, the Doctor has been present at or directly involved in countless major historical events on the planet Earth and elsewhere — sometimes more than once. In the 2005 series premiere, "Rose", it's revealed that the Ninth Doctor was instrumental in preventing a family from boarding the Titanic prior to her fateful voyage. In "The End of the World", the Doctor claimed to have been on board and survived the Titanic's sinking to find himself 'clinging to an iceberg.' The Fourth Doctor also mentioned this event in Robot and The Invasion of Time, where he claims the sinking wasn't his fault.
   Many historical figures on Earth have also encountered the Doctor. In City of Death it's revealed that the Doctor has met Leonardo da Vinci and William Shakespeare (whom he re-met in "The Shakespeare Code"), and that the first folio of the latter's Hamlet was transcribed by the Doctor himself (City of Death). He has also met a young H. G. Wells (Timelash), Albert Einstein (Time and the Rani), Mao Zedong (The Mind of Evil), Richard the Lionheart (The Crusade), Wyatt Earp (The Gunfighters) and Marco Polo (Marco Polo). More recently, the Doctor has shared adventures with Charles Dickens ("The Unquiet Dead"), Agatha Christie ("The Unicorn and the Wasp"), Queen Victoria ("Tooth and Claw"), and Madame de Pompadour ("The Girl in the Fireplace"). A photograph seen in the 2005 series shows that the Ninth Doctor witnessed the death of US president John F. Kennedy.
   It is this penchant for becoming "involved" with the universe — in direct violation of official Time Lord policy — that has caused the Doctor to be labelled a renegade by the Time Lords. Most of the time, however, his actions are tolerated, especially given that he's saved not just Gallifrey but also the universe several times over. The Time Lords are also partial to sending him on missions when deniability or expendability is needed. The Doctor's standing in Time Lord society has waxed and waned over the years, from being a hunted man to being appointed Lord President of the High Council (he doesn't assume the office for very long, and is eventually removed from it in his absence). However, some Time Lords respect him to some degree for his heroic deeds. In the end, though, the Doctor has always seemed quite content to remain a renegade and an exile.
   By the time of his ninth incarnation, the Doctor believes himself to be the last surviving Time Lord following the Last Great Time War, although he learns in his tenth incarnation that the Master also survived ("Utopia"). Despite the Doctor's desperate attempts to save the Master from his evil ways, the Master is shot by his wife and refuses to regenerate, seemingly leaving the Doctor alone once more ("Last of the Time Lords"). However, the final scenes involving the Master's body leave the possibility of future regeneration open.

"Doctor who?"

In the first episode, Barbara addresses the Doctor as "Doctor Foreman", as this is the surname the Doctor's granddaughter Susan goes by, and the junkyard in which they find him bears the sign "I.M. Foreman". When addressed by Ian with this name in the next episode, the Doctor responds, "Eh? Doctor who? What's he talking about?" Later, when he realises that "Foreman" isn't the Doctor's name, Ian asks Barbara, "Who is he? Doctor who?" (In an ultimately-unused idea from documents written at the series' inception, Barbara and Ian would have subsequently referred to the Doctor as 'Dr. Who', given their not knowing his real given name.)
Similarly, in the 2005 series premiere, "Rose", when asked his name, the Doctor replies, "Just 'The Doctor'." New companion Rose Tyler later finds a website devoted to the Doctor on the Internet, run by a conspiracy theorist who has been tracking the Ninth Doctor's appearances throughout history, carrying the title "DOCTOR WHO?" (see Doctor Who tie-in websites). The BBC launched a "real" version of this website at "WHO IS DOCTOR WHO?"

, with the idea that it's run by Mickey Smith, Rose's boyfriend (having taken over the site following the death of its originator).
   In "The Empty Child" (2005), for want of a better name, Rose introduces the Doctor to Jack Harkness as "Mr. Spock". (According to the DVD commentary for this episode, the Doctor was originally to have responded "I'd rather have 'Doctor Who' than Star Trek".)
   Although listed in the on-screen credits for nearly twenty years as "Doctor Who" or "Dr Who", the Doctor is never really called by that name in the series, except in that same tongue-in-cheek manner (for example, in The Five Doctors when one character refers to him as "the Doctor", another character asks, "Who?"). The only real exception is the computer WOTAN in the serial The War Machines, which commands that "Doctor Who is required." The Third Doctor's automobile, dubbed "Bessie", carried the licence plate WHO 1, the only ongoing reference to the "Doctor Who" enigma in the original series. The Third Doctor also later drove an outlandish vehicle called the "Whomobile". However, this name was only applied to it in publicity and it's never referred to as such in the series, being simply known as "the Doctor's car". The name "Doctor Who" is also used in the title of the serial Doctor Who and the Silurians, but this was a captioning mistake and not an in-story mention. The only other time this occurs is in the title of Episode 5 of The Chase: "The Death of Doctor Who".
   In the Third Doctor serial The Dæmons the Doctor is briefly given the alias of the Great Wizard Qui Quae Quod. This is actually the masculine, feminine and neuter forms of the interrogative "who" in the Latin language.
   In "The Girl in the Fireplace" (2006), Madame de Pompadour reads the Doctor's mind and remarks about his name, "Doctor who? It's more than just a secret, isn't it?" In the podcast commentary on the BBC website, writer Steven Moffat suggests that, as the Doctor doesn't tell even his closest companions his name, there must be a "dreadful secret" about it. Within the same commentary, Moffat and actor Noel Clarke jokingly suggest his name to be "Curtis". Ironically, according to the in-vision commentary on the DVD release, David Tennant had to inform actress Sophia Myles (who played Madame de Pompadour) that she was not, in fact, revealing the Doctor's surname as she believed was the intent of the dialogue. In "The Shakespeare Code" the Carrionite Lilith remarks, "Why would a man hide his title in such despair?", and a psychically-inspired human in "The Fires of Pompeii" again remarks that his name Doctor is "false" and that his "true name" is in fact "hidden". Doctor Who spin-off media, which are of uncertain canonicity, have suggested that the character uses the name "the Doctor" because his actual name is impossible for humans to pronounce. This is also repeated by companion Peri Brown in the radio serial Slipback. The Faction Paradox encyclopedia, The Book of the War, which is of dubious canonicity, states that all renegades from the Homeworld/Gallifrey abandon their names to symbolise how they leave their culture. Peter Cushing, in the films Dr. Who and the Daleks and Daleks — Invasion Earth 2150 AD referred to himself as "Dr. Who". However, these films are not considered canon with the rest of the series, even though they were based on the first two Dalek adventures with William Hartnell.

Alias the Doctor

Quite apart from his name, why the Doctor uses the title of "the Doctor" has never been explained on screen. The Doctor, at first, said that he wasn't a medical doctor, often referring to himself as a scientist or an engineer. However he does occasionally show medical knowledge and has stated that he studied under Joseph Lister and Joseph Bell on separate occasions. In The Moonbase, the Second Doctor mentions that he studied for a medical degree in Glasgow during the 19th Century. He has also been mocked by his fellow Time Lords for adhering to such a "lowly" title as "Doctor", although in The Armageddon Factor he tells Drax that he achieved his doctorate, indicating it was at least a somewhat respectable title. In "The Girl in the Fireplace", he draws an analogy between the title and Madame de Pompadour's. In "The Sound Of Drums", the Master remarks to the Doctor that they both chose their names, and that it was sanctimonious of the Doctor to identify himself as "the man who makes people better", as well as the fact that one of the Master's assistants calls him a doctor of "everything".
   The Telos novella Frayed by Tara Samms (which takes place prior to "An Unearthly Child") has the First Doctor being given that title by the staff of a besieged human medical facility on the planet Iwa, suggesting at the end that the Doctor liked the official title so much that he adopted it. However, this doesn't quite explain why the Time Lords use the same title in addressing him. The same story also has Jill, a young girl living in the facility, naming the Doctor's granddaughter "Susan" after Jill's mother. The canonicity of all non-television sources is uncertain.
   To make up for his lack of a practical name, the Doctor often relies upon convenient pseudonyms. In The Gunfighters, the First Doctor uses the alias Dr. Caligari. In The Highlanders the Second Doctor assumes the name of "Doctor von Wer" (a German approximation of "Doctor Who"), and signs himself as "Dr. W" in The Underwater Menace. In The Wheel in Space, his companion Jamie McCrimmon, reading the name off some medical equipment, tells the crew of the Wheel that the Doctor's name is "John Smith". The Doctor subsequently adopts this alias several times over the course of the series, often prefixing the title "Doctor" to it. This name is particularly prominent during his third incarnation when, as scientific advisor to UNIT, he gives it to Brigadier Lethbridge-Stewart to be put on his official credentials. The Eighth Doctor's companion Grace briefly refers to him by the alias "Dr Bowman" in the 1996 Doctor Who television movie.
   In "New Earth", it's implied that the Doctor is part of the prophecy of the Face of Boe and is referred to as "The Lonely God". In "Tooth and Claw", having landed in Scotland, the Tenth Doctor introduces himself as "Dr James McCrimmon" from the township of Balamory. James Robert McCrimmon is in fact the full name of the Second Doctor's companion more commonly known as Jamie. Later in that episode, the Doctor is knighted by Queen Victoria as "Sir Doctor of TARDIS."
   To his greatest enemies, the Daleks, the Doctor is known as the Ka Faraq Gatri, the "Bringer of Darkness", "Destroyer of Worlds" or "The Oncoming Storm". This is first mentioned in the novelisation of Remembrance of the Daleks by Ben Aaronovitch and subsequently taken up in the spin-off media, particularly the Virgin New Adventures books and the Doctor Who Magazine comic strip. In "The Parting of the Ways", the Doctor claims that the Daleks call him "The Oncoming Storm" — this name is used by the Draconians (whose word for it's "Karshtakavaar") to refer to the Doctor in the Virgin New Adventures novel Love and War by Paul Cornell.
   The series has also occasionally toyed with the Doctor's identity (or lack thereof). In the first part of The Mysterious Planet, the Doctor suggests writing a thesis on "Ancient Life on Ravolox, by Doctor...", but is interrupted by Peri. In The Armageddon Factor, the Time Lord Drax addresses the Fourth Doctor as "Thete", short for "Theta Sigma"; later, in The Happiness Patrol, this was clarified as a nickname from the Doctor's University days. In Remembrance of the Daleks the Seventh Doctor produces a calling card with a series of pseudo-Greek letters inscribed on it (as well as a stylised question mark). This may be a reference to Terrance Dicks' and Malcolm Hulke's book The Making of Doctor Who (1972), which claims that the Doctor's true name is a string of Greek and mathematical symbols.
   The question mark motif was common throughout the eighties, in part as a branding attempt. Beginning with season eighteen, the Fourth through Seventh Doctors all sported costumes with a question mark motif (usually on the lapels, except in the Seventh Doctor's case on his pullover and the shape of his umbrella handle). In the 1988 serial Remembrance of the Daleks, the Seventh Doctor is asked to sign a document; although the signature itself isn't directly seen on screen, his hand movements clearly indicate that he signs it with a question mark.
   It was mentioned by Tom Baker, the Fourth Doctor, during an interview with The Age in 2003, that the Doctor is called so because he's "a doctor of time and relative dimension in space". Apart from being called a doctor of the TARDIS, the Doctor has also been referred to as just a "doctor of time travel".

On-screen credits

In the early years of the spin-off comic strips, books, films and other media, the character was initially called "Doctor Who" (or just "Dr Who") in the stories as a matter of course. This usage declined as the years went by.
Perhaps complicating the matter is that, from the first television serial through to Logopolis (the last story of Season 18 and also of the Tom Baker era), the lead character was credited as "Doctor Who" (or sometimes "Dr Who"). Starting from Peter Davison's first story, Castrovalva (the first story of the series' Season 19) to the end of Season 26, he's credited simply as "The Doctor".
This format is continued in the 1996 television movie for Paul McGann's credit, while Sylvester McCoy's incarnation is credited as "The Old Doctor". For the 2005 revival starring Christopher Eccleston, the credit reverted to "Doctor Who". However, in "New Earth", and subsequent stories featuring David Tennant, the character is once again identified in the closing credits as "The Doctor", with The Christmas Invasion being the only episode to feature David Tennant in which he's credited as playing "Doctor Who". According to Doctor Who Magazine #367 this reversion was specifically requested by Tennant.

Changing faces

The changing of actors playing the part of the Doctor is explained within the series by the Time Lords' ability to regenerate after suffering illness, mortal injury or old age ("wearing a bit thin"). The process repairs and rejuvenates all damage, but as a side-effect it changes his physical appearance and personality. This ability wasn't introduced until producers had to find a way to replace the ailing William Hartnell with Patrick Troughton and wasn't explicitly called "regeneration" until Jon Pertwee's transformation to Tom Baker at the climax of Planet of the Spiders (1974). On screen, the transformation from Hartnell to Troughton was called a "renewal" and from Troughton to Pertwee a "change of appearance".
The original concept of regeneration or renewal was that the Doctor's body would rebuild itself in a younger, healthier form. The Second Doctor was intended to be a literally younger version of the First; biological time would turn back, and several hundred years would get taken off the Doctor's age, rejuvenating him. In practice, however, after the Doctor stated his age in the Second Doctor serial The Tomb of the Cybermen (1967), the Doctor's age has been recorded progressively, however many regenerations the Doctor goes through (but see below). Coincidentally or otherwise, the general trend has been toward increasingly younger actors for the role.
The actors who have played the Doctor in the series, and the dates of their first and last regular television appearances in the role, are:

First Doctor - William Hartnell: (23 November 1963 – 29 October 1966), Richard Hurndall (25 November 1983)
Second Doctor - Patrick Troughton: (29 October 1966 – 21 June 1969)
Third Doctor - Jon Pertwee: (3 January 1970 – 8 June 1974)
Fourth Doctor - Tom Baker: (8 June 1974 – 21 March 1981)
Fifth Doctor - Peter Davison: (21 March 1981 – 16 March 1984)
Sixth Doctor - Colin Baker: (16 March 1984 – 6 December 1986)
Seventh Doctor - Sylvester McCoy: (7 September 1987 – 6 December 1989 in the series, and 27 May 1996 in the Doctor Who film)
Eighth Doctor - Paul McGann: (27 May 1996, in the Doctor Who film).
Ninth Doctor - Christopher Eccleston: (26 March 2005 – 18 June 2005)
Tenth Doctor - David Tennant: (18 June 2005 – present day)

Personality

Throughout his regenerations, the Doctor's personality has retained a number of consistent traits. Its most notable aspect is an unpredictable, affable, clownish exterior concealing a well of great age, wisdom, seriousness and even darkness. While the Doctor can appear childlike and jocular, when the stakes rise, as, for example, in Pyramids of Mars, he'll often become cold, driven and even callous. Another aspect of the Doctor's persona, which, though always present, has been emphasised or downplayed from incarnation to incarnation, is compassion. The Doctor is a fervent pacifist and is dedicated to the preservation of sentient life, human or otherwise, over violence and war, even going so far as to doubt the morality of destroying his worst enemies, the Daleks, when he's the chance to do so in Genesis of the Daleks, and again in "Evolution of the Daleks". He also, in The Time Monster, begs Kronos to spare the Master torment or death, unintentionally winning the evil Time Lord's freedom, which he tells Jo Grant was preferable anyway, and forgives the Master for his actions in "The Sound of Drums" and "Last of the Time Lords", vowing to take responsibility for his former friend.
Nonetheless, the Doctor will kill when given no other option and occasionally in self-defence; Davies also said that after Eccleston's accent, he didn't want Tennant "touring the regions" with a Scottish one, and so asked Tennant to affect the same accent he used for the earlier BBC period drama Casanova.

Changing fashions

The Doctor's clothing has been equally distinctive, from the distinguished Edwardian suits of the First Doctor to the Second Doctor's rumpled, Chaplinesque attire to the frills and velvet of the Third Doctor's era. The Fourth Doctor's long frock coat, loose fitting trousers, occasionally worn wide-brimmed hat and trailing, multistriped scarf added to his somewhat shambolic and bohemian image; the Fifth's Edwardian cricketer's outfit suited his youthful, aristocratic air as well as his love of the sport (with a stick of celery on the lapel for an eccentric touch); and the Sixth's multicoloured jacket, with its cat-shaped lapel pins, reflected the excesses of 1980s fashion. The Seventh Doctor's outfit — a straw hat, a coat with two scarves, a tie, checked trousers and brogues/wingtips — was more subdued and suggestive of a showman, reflecting his whimsical approach to life. In later seasons, as his personality grew more mysterious, his jacket, tie, and hatband all grew darker.
   Throughout the 1980s, question marks formed a constant motif, usually on the shirt collars or, in the case of the Seventh Doctor, on his sleeveless jumper and the handle to his umbrella. The idea was grounded in branding considerations, as was the movement starting in Tom Baker's final season toward an unchanging costume for each Doctor, rather than the variants on a theme employed over the first seventeen years of the programme. When the Eighth Doctor regenerated, he clad himself in a 19th century frock coat and shirt based around a Wild Bill Hickok costume, reminiscent of the out-of-time quality of earlier Doctors and emphasising the Eighth Doctor's more Romantic persona.
   In contrast to the more flamboyant outfits of his predecessors, the Ninth Doctor wore a nondescript, worn black leather jacket, V-neck jumper and dark trousers. Eccleston stated that he felt that such definitive "costumes" were passé and that the character's trademark eccentricities should show through their actions and clever dialogue, not through gimmicky costumes. Despite this, there's a running joke about his character that the only piece of clothing he changes is his jumper, even when trying to "blend into" an historical era. The one exception, a photograph of him taken in 1912, wearing period gentleman's clothing, resembles the style of the Eighth Doctor.
   The Tenth Doctor sports either a blue or a brown pinstripe suit - usually worn with ties - a tan ankle-length coat and trainers, the latter recalling the plimsolls worn by his fifth incarnation. Also like that incarnation (and his first one), he occasionally wears spectacles: a pair with brown, thick-rimmed frames. It is revealed in the 2007 Children in Need Special that he doesn't actually need the glasses to see, but rather wears them to look clever. In interviews, Tennant has referred to his Doctor's attire as geek chic. According to Tennant he'd always wanted to wear the trainers, however, the overall costume was influenced by an outfit worn by Jamie Oliver in a TV interview on the talk show Parkinson.
   The Tenth Doctor says in "The Runaway Bride" that, like the TARDIS, his pockets are bigger on the inside. The Second, Fourth and Seventh Doctors routinely carried numerous items in their coats without this being conspicuous.

Transitions

Save for the off-screen transition between the Eighth and Ninth Doctors, to date each regeneration has been worked into the continuing story. Also, most regenerations (save the Second-to-Third and Eighth-to-Ninth transitions) have been portrayed on-screen, in a symbolic handing over of the role. The following list details the manner of each regeneration:

First Doctor (Hartnell): apparently succumbed to old age, steadily growing weaker throughout The Tenth Planet and collapsing at the serial's end. Although the writer's intent was that this was due to the energy drain from the planet Mondas, this wasn't made clear in the transmitted story.

Second Doctor (Troughton): a forced "change in appearance" and exile to Earth by the Time Lords in the closing moments of The War Games.

Third Doctor (Pertwee): radiation poisoning from the Great One's cave of crystals at the end of Planet of the Spiders.

Fourth Doctor (Baker, T): fell from the Pharos Project radio telescope in Logopolis.

Fifth Doctor (Davison): spectrox toxaemia, contracted near the start of The Caves of Androzani.

Sixth Doctor (Baker, C): suffered unspecified injuries when the Rani attacked the TARDIS and caused it to crash land at the start of Time and the Rani.

Seventh Doctor (McCoy): died in San Francisco during exploratory heart surgery by a doctor unfamiliar with Time Lord physiology, after being hospitalised for non-life threatening gunshot wounds in the 1996 television movie.

Eighth Doctor (McGann): not yet revealed. Implied to be a result of the Time War.

Ninth Doctor (Eccleston): cellular degeneration caused by absorbing the energies of the space-time vortex from Rose, which she in turn had absorbed through the heart of the TARDIS in "The Parting of the Ways". In the original series, with the exception of the change from Troughton to Pertwee, regeneration usually occurred when the previous Doctor was near "death". The changeover from McCoy to McGann was handled differently, with the Doctor actually dying and being dead for quite some time before regeneration occurred. The Eighth Doctor comments at one point in the television movie that the anesthesia interfered with the regenerative process, and that he'd been "dead too long", accounting for his initial amnesia.
The 2005 series began with the Ninth Doctor already regenerated and fully stabilized, with no explanation given. In his first appearance in "Rose", the Doctor looked in a mirror and commented on the size of his ears, suggesting that the regeneration may have happened shortly prior to the episode, or that he hasn't examined himself in the mirror recently. However, the Ninth Doctor's appearances in old photographs, without being accompanied by Rose, may also suggest that he'd been regenerated for some time. Russell T. Davies, writer/producer of the new series, stated in Doctor Who Magazine that he's no intention of showing the regeneration in the series, and that he believed the story of how the Eighth Doctor became the Ninth is best told in other media. In Doctor Who Confidential Davies revealed his reasoning that, after such a long hiatus, a regeneration in the first episode wouldn't just be confusing for new viewers but also lack dramatic impact, as there would be no emotional investment in the character before he was replaced.
Eccleston stepped down from the role at the end of the 2005 series, and the Ninth Doctor regenerated into the Tenth in "The Parting of the Ways". It remains to be seen whether the Ninth Doctor will appear again, although Russell T. Davies has stated that he doesn't intend to bring back former Doctors. (Despite this, Peter Davison did briefly reprise the role of the Fifth Doctor in the 2007 Children in Need charity special alongside Tenth Doctor David Tennant.)

Regenerations

It was established in The Deadly Assassin (1976) that a Time Lord can regenerate twelve times before permanently dying - a total of thirteen incarnations. In the 1996 television movie the Eighth Doctor explicitly said that a Time Lord has "thirteen lives". (The Doctor's enemy, The Master has, however, been shown circumventing this limit on several occasions.) In "The Christmas Invasion" it was stated the regenerative cycle creates a large amount of energy that suffuses the Time Lord's body. As demonstrated by the Tenth Doctor for the first time in that story, in the first fifteen hours of regeneration this energy is enough to even rapidly regrow a severed hand.
   The Doctor's regenerations are usually as a result of his previous incarnation sustaining mortal injury or (in one case) having a change forced on him by the Time Lords. Other Time Lord regenerations, like Romana's, have not been as dramatic or painful.
   The Doctor frequently experiences a period of instability and partial amnesia following regeneration. Some post-regeneration experiences have been more difficult than others. In particular, the Fifth Doctor began reverting to his previous personalities and required the healing powers of the TARDIS's "Zero Room" to recuperate (Castrovalva). The Sixth Doctor experienced extreme paranoia and flew into a murderous rage, nearly killing his companion (The Twin Dilemma). The Eighth Doctor experienced amnesia (1996 Doctor Who television movie).
   The regeneration from the Ninth to the Tenth Doctor at first seemed smooth, with the Doctor regenerating standing up for the first time ("The Parting of the Ways"). However, shortly afterwards he began to experience spasms and became somewhat manic, frightening his companion as he pushed the TARDIS to dangerous extremes . After crash-landing the TARDIS, the Doctor collapsed and remained unconscious for most of the next fifteen hours ("The Christmas Invasion"). The experience was traumatic enough to cause one of his hearts to temporarily stop beating.
   As noted above, the newly regenerated Tenth Doctor was able to regrow his hand when it was severed at the wrist during a swordfight with the Sycorax leader. This ability had never been exhibited before, but no previous Doctor had ever suffered an injury of this nature so soon after regeneration (although Romana did exhibit some degree of control over her regenerative process). The Tenth Doctor's lack of reaction to the injury may also point to increased pain tolerance during this period.
   The TARDIS also appears to aid in the regenerative process. Of the four occasions the Doctor regenerates outside the TARDIS, one was forced on him by the Time Lords (The War Games), one required a Time Lord to give the Doctor's cells a "little push" to start the process (Planet of the Spiders), one needed the TARDIS Zero Room to help him recover (Castrovalva) and the last apparently occurred a few hours after he'd actually "died", leaving him with temporary amnesia (the 1996 television movie).

Continuity curiosities

Over the years, different writers and production teams have introduced their own twists to the Doctor's character, sometimes as part of a grand creative reinvention; others, out of narrative convenience or outside pressures. Without one driving vision to maintain continuity, newer details may occasionally seem to contradict earlier ones. Other details — sometimes significant ones — are later ignored, sometimes leading to argument amongst series fans as to how, or whether, these details apply in a broader context.
   In the early serials The Edge of Destruction and The Sensorites, it appeared that the First Doctor had only a single heart. The novel The Man in the Velvet Mask by Daniel O'Mahony suggests that Time Lords only grow their second heart during their first regeneration. In The Mind of Evil, "The Christmas Invasion" and "The Shakespeare Code" one of the Doctor's hearts temporarily stops beating due to intense trauma.
   Also during his first regeneration, and for similarly unclear reasons, the Doctor's clothes (save for his cloak and ring, both of which quickly thereafter fall off) changed along with his body (The Power of the Daleks); on all subsequent regenerations, the new Doctor generally continues to wear the clothing he regenerated in (albeit changed enough to fit the new body) until he selects a new outfit (though due to a continuity error, the regeneration from the Fourth to the Fifth Doctors included a change of footwear).
   In The Brain of Morbius (produced shortly before The Deadly Assassin), visual images displayed during a mental battle between the Fourth Doctor and Morbius can be taken as implying that the Doctor had at least eight incarnations prior to the First Doctor. However, multiple dialogue references throughout the series (particularly in The Three Doctors, Mawdryn Undead and The Five Doctors) contradict this, as well as the fact that the Doctor has regenerated six times since then (as stated in "School Reunion"). Explanations have included theories that the images were of Morbius's previous incarnations (two images that are certainly Morbius also appear, and the game seems to have a symmetrical arrangement), or false images induced by the Doctor. The Doctor Who novels have suggested that these may have been faces of the Other, a figure from Gallifrey's ancient past and the genetic predecessor of the Doctor (although being from the tie-in novels, the canonicity of this character is debatable). The producers, however, intended that these were, in fact, figures from the Doctor's past. Producer Philip Hinchcliffe has said, "We tried to get famous actors for the faces of the Doctor. But because no one would volunteer, we'd to use backroom boys. And it's true to say that I attempted to imply that William Hartnell wasn't the first Doctor." Other indications are given on screen to suggest the same thing, such as the references from the 'Cartmel Masterplan' and the secondary control room, which the Doctor says he used before (The Masque of Mandragora). The alternate console room also contained articles connected to the second (a recorder) and third (a ruffled-front shirt) Doctors, suggesting use of the room during those incarnations.
   In the Sixth Doctor story arc The Trial of a Time Lord, a Time Lord with the title of the Valeyard (played by Michael Jayston) was revealed to be a potential future Doctor, a "distillation" created somewhere between his twelfth and final incarnations and embodying all the evil and malevolence of the Doctor's dark side. The Valeyard was defeated in his attempt to actualise himself by stealing the Sixth Doctor's remaining regenerations, however, and so may never actually come to exist.
   The idea of an "in-between" version of the Doctor has its precedents. In Planet of the Spiders, a Time Lord's future self (described as a "distillation" of the future incarnation) was shown to exist as a corporeal projection that assisted his then-current incarnation. In Logopolis, an eerie and mysterious white-clad figure known as the Watcher assisted in the transition between the Fourth and Fifth Doctors. Nyssa commented that the Watcher "was the Doctor all the time" as he merged with the prone form of the fourth Doctor, regeneration beginning just before the merging is complete.
   Perhaps the most controversial element from the 1996 television movie was the revelation that the Doctor is half-human ("on [his] mother's side"). The spin-off novels and audios have tried various methods to explain this revelation, suggesting that the Doctor retained some human DNA from his time as Dr John Smith (in which the Doctor, using bought technology, became biologically human with a different persona unaware of his Time Lord self) in the Virgin New Adventures novel Human Nature, that his origins have become muddied by agents manipulating his personal timestream (the Eighth Doctor Adventures novel Unnatural History), or that only his mother's incarnation at the time of his birth was Human. In the New Series Adventures novel The Deviant Strain by Justin Richards, the Doctor comments that his DNA is "close" to that of humans. However, as noted above, the canonicity of the novels is uncertain.
   The Time Lord ability to change species during regeneration is referenced by the Eighth Doctor in relation to the Master in the television movie, being supported by Romana's regeneration scene in the 1979 serial Destiny of the Daleks. The Daleks also implied during the events of The Daleks' Master Plan (1965–66) that the First Doctor's humanoid form isn't his actual appearance. The new series hasn't made any allusions to mixed parentage, simply referring to the Doctor as "alien" or "Time Lord". However, the trade paperback Doctor Who: The Legend Continues by Justin Richards, published to coincide with the new series, refers to the Doctor as half-human. The 2007 Tenth Doctor episodes "Human Nature" and "The Family of Blood", adapted from the above-mentioned Seventh Doctor novel, Human Nature, also show the Doctor using technology to become biologically human, although he does so through Time Lord science. Later, in "Utopia", the Master is revealed to have undergone the same process.

When incarnations meet

Due to time travel, it's possible for the Doctor's various incarnations to encounter and interact with each other, although this is supposed to be prohibited by the First Law of Time (as stated in The Three Doctors) or permitted only in the "gravest of emergencies" (The Five Doctors). In the 1963–1989 television series, such encounters were seen on three occasions, in The Three Doctors (1972), The Five Doctors (1983) and The Two Doctors (1985). In Day of the Daleks (1972), the Third Doctor and Jo Grant very briefly met their future selves due to a glitch during a temporal experiment (the serial was supposed to end with the same scene depicted from the perspective of the "other" Doctor and Jo, but was excised because it was anticlimactic). In "Father's Day" (2005), the Ninth Doctor and Rose observed but didn't interact with past versions of themselves; when Rose changed history, the earlier selves vanished and a temporal paradox was created that attracted the extradimensional Reapers. The Tenth and Fifth Doctors met in the TARDIS in the mini-episode "Time Crash", which aired on 16 November, 2007 as part of the BBC's annual Children in Need appeal. This marks the first time the Doctor has met a previous incarnation since the show's revival. Although the scene aired outside the series itself, it was established as taking place between the events of "Last of the Time Lords" and "Voyage of the Damned"
   The BBC novel The Eight Doctors was written by respected Doctor Who writer Terrance Dicks, the same author who wrote The Five Doctors. In it, he tries to reconcile the continuity errors of the 1996 movie, while having the Eighth Doctor meet and interact with each of his previous selves.
   Physical contact between two versions of the same person can lead to an energy discharge that shorts out the "time differential". This is apparently due to a principle known as the Blinovitch Limitation Effect, and was seen when the past and future versions of Brigadier Lethbridge-Stewart touched hands in Mawdryn Undead. Oddly, the Doctor's incarnations don't appear to suffer this effect when encountering each other and shaking hands. This has never been explained. An essay in the About Time series by Lawrence Miles and Tat Wood suggests that Time Lords are somehow exempt from the effect by their very nature. Rose Tyler is seen holding an infant version of herself in "Father's Day", with no visible energy discharge, but the contact does allow the Reapers to enter the church in which the Doctor and several others are taking refuge. While doing a live commentary on the episode at the 2006 Bristol Comic Expo, episode author Paul Cornell said that this is supposed to be due to the Blinovitch Limitation Effect, even though it isn't mentioned by name. He also suggested that the lack of a spark may be down to the fact that the Time Lords were no longer around to manage anomalies.
   The interaction of the Doctor's various incarnations produces a continuity anomaly that requires suspension of disbelief on the part of viewers, as one may assume that his past selves would forget that he'd later regenerate. In Castrovalva, the newly-regenerated Fifth Doctor clearly indicates that the outcome of his regeneration can't be predicted; however, the Fifth Doctor should have had memories from his earlier incarnations of having met himself per the events of The Three Doctors and The Five Doctors. Also, the Second, Third and Fifth Doctors should be already familiar with the events of The Five Doctors, having already lived through them multiple times. It has been suggested in fandom that the Time Lords erase the Doctor's memory after such encounters (and in The Two Doctors there's mention of Dastari administering to the Second Doctor a drug that he bemoans "affects the memory"); the novel The Empire of Glass features the First Doctor directly after his return from the events of The Three Doctors, his memory of the adventure having been totally erased barring a vague recollection of meeting "a dandy and a clown". The Virgin Missing Adventures novel Cold Fusion by Lance Parkin suggests that memory-erasure is sometimes, but not always, due to something called "Blinovitch Conservation".
   In the 2006 episode "School Reunion", the Tenth Doctor and Sarah Jane Smith both seem to indicate in dialogue that they haven't seen each other since her departure from the TARDIS in The Hand of Fear, although this contradicts their having met later during The Five Doctors. She, in that story, doesn't realise that the Fifth Doctor is a later incarnation of the third and fourth Doctors with whom she'd previously travelled. In "Time Crash", the Tenth Doctor remembers and reproduces what he saw himself do when he was the Fifth Doctor, a fact that seems to surprise the Fifth Doctor himself.
   Russell T Davies has expressed a dislike for stories in which multiple incarnations of the Doctor meet, stating that he believes they focus more on the actors than on the story itself. Since the series revival, there has been one multi-Doctor story, the Children in Need special Time Crash. Before that, the only references to past incarnations (from 1963 to 1996) have been in the aforementioned episode "School Reunion" (in which the Doctor acknowledges having regenerated "half a dozen times" since last seeing Sarah Jane) and in drawings that the Doctor (who has temporarily become human to hide from the Family Of Blood) makes based on dreams of his other life in the 2007 episode "Human Nature". Seen on screen are the First, Fifth, Sixth, Seventh and Eighth Doctors, but a fuller view briefly available on the BBC website depicted all ten incarnations. Time Crash featured Peter Davison returning as the Fifth Doctor. This event is explained as occurring due to the current Doctor having left his shields down when rebuilding the TARDIS following "Last of the Time Lords" and then accidentally crossing the Fifth Doctor's timeline, allowing the two TARDISes to merge. When the Tenth Doctor effortlessly averts the impending Belgium-sized hole in the Universe caused by this temporal anomaly, he reveals having known what to do because he saw himself do it as the Fifth Doctor and remembered. He goes on to tell the Fifth Doctor how fond he was of his incarnation and how he influences the current Doctor's personality.

Reprising the role

On a few occasions, previous Doctors have returned to the role, guest-starring with the incumbent:

William Hartnell and Patrick Troughton with Jon Pertwee in The Three Doctors. Originally Hartnell's role had been intended to be more extensive, but his health had deteriorated to the extent that he could only make a limited appearance. In the end, it turned out to be his last television role.

Troughton and Pertwee with Peter Davison in The Five Doctors, the twentieth anniversary special, with another actor, Richard Hurndall, standing in for the late William Hartnell (the story began with a clip from The Dalek Invasion of Earth featuring Hartnell himself). Tom Baker declined to appear, feeling that the role came too soon after he'd left the programme (a decision he later said he regretted) and the narrative was reworked to use clips from Shada, an intended six-part story from the Fourth Doctor's era that was never completed due to industrial action. A waxwork dummy of Baker from Madame Tussauds was used in the publicity photographs.

Patrick Troughton with Colin Baker in The Two Doctors.

Jon Pertwee, Tom Baker, Peter Davison, Colin Baker, and Sylvester McCoy — with rubber dummy heads standing in for the late William Hartnell and the late Patrick Troughton — in Dimensions in Time, a charity special in aid of Children in Need in 1993, the programme's 30th anniversary year. Except for the mannequin versions of Hartnell and Troughton, no two Doctors are shown on screen at the same time. (Ultimately, the canonicity of Dimensions in Time is still a matter of debate).

Peter Davison, Colin Baker and Sylvester McCoy with Paul McGann in the audio adventure Zagreus, a fortieth anniversary special and the fiftieth release, with Jon Pertwee posthumously joining them by virtue of an extant fan recording. The first three had also united for the first Big Finish audio adventure, The Sirens of Time.

Peter Davison with David Tennant in the 2007 Children in Need special "Time Crash". Other actors have portrayed the character of the Doctor outside of the television series. For details on this see under Adaptations and other appearances in the main article and Doctor Who spin-offs.

Age

In early production documents, the Doctor was said to be 650 years old, although this was never stated on screen. and in "Aliens of London", he says, "Nine hundred years of time and space, and I've never been slapped by someone's mother." Rose follows up by asking him if he's 900 years old, and he replies affirmatively, though it's unclear whether he's being disingenuous. He restates this as "Nine hundred years of phone box travel and it's the only thing left that surprises me", however, in "The Empty Child". In "Voyage of the Damned", the Tenth Doctor states that he's 903 years of age, the first time since Time and the Rani that an exact number has been stated in dialogue; previously, the Master also indicated the Doctor's age to be about 900 in the "The Sound of Drums"/"Last of the Time Lords" story arc.
   How this figure is to be reconciled with the Doctor's age in the rest of the series and spin-off media is uncertain. In the 2006 episode "Rise of the Cybermen", the Doctor transfers part of his life energy to a component of the TARDIS in hopes of regenerating the disabled craft; he states that he's given up 10 years of life in doing so.
   At the end of "The Sound of Drums", the Master ages the Doctor by 100 years using his laser screwdriver, leading the Doctor to assume an elderly appearance. In "Last of the Time Lords", the Master states to the population of Earth that the Doctor is nine hundred years old, and informs his subjects he'll show them the Doctor's true form, suspending his ability to regenerate. The Master proceeds to age the Doctor further with his laser screwdriver, reducing him to a tiny, wrinkled being subsequently imprisoned inside a bird cage until reverted to his current form with the help of Martha Jones and the entire population of Earth.
   As for the Doctor's ability, at one point, to gain many years to his age and not show sign of it and, later on, to age a century and become a shriveled old man, it's stated in the novel Lungbarrow that "later regenerations tend to be shorter in their longevity."

Romance

In the very first episode of the television series it's established that Susan Foreman is the Doctor's granddaughter, but neither Susan nor the Doctor ever speaks of her parents. In "Fear Her" (2006), the Doctor states that he was "a dad once", suggesting that he reproduced at some point. Furthermore, in "The Doctor's Daughter", he says he fathered offspring, now dead. Thus, the Doctor's family history, including the time period "before" the beginning of the series, is largely a matter of conjecture.
   During the initial series, William Hartnell's age precluded any involvement of the character with the only other female lead at the time. The First Doctor did flirt with — and was accidentally engaged to — the character Cameca in The Aztecs; although this was part of a ploy to get the TARDIS back, there was a hint of mutual attraction in Hartnell's performance (especially as he's ultimately unable to leave behind the love token she's given him). The fact that the TARDIS crew kept pressing forward in their travels was probably also a factor in preventing any romantic attachments.
   As the series progressed and grew more popular among children, the Doctor was firmly established as an avuncular figure to his younger companions, the one exception being the Third Doctor's hurt reaction to his companion Jo Grant's leaving him for an idealistic scientific adventurer whom she describes as "a younger version" of the Doctor (The Green Death). Jo kisses the Doctor on the cheek before she departs, the second time this form of affection had been shown on screen (the second Doctor having similarly kissed Zoe in The War Games).
   Despite the press (and, occasionally, the production team) trying to play up the sexiness of some of the female companions or suggesting "hanky panky" in the TARDIS, the series reached the point where any suggestion of the Doctor as a sexual being was avoided altogether. One example was during City of Death, when the Fourth Doctor says to Countess Scarlioni, "You're a beautiful woman, probably," suggesting that he's incapable of appreciating a human woman's attractiveness. This rule held true even when the Doctor's apparent age was closer to those of his companions, or if there was on-screen chemistry between the actors, as there was between Fourth Doctor Tom Baker and his wife-to-be Lalla Ward's Romana II. In fact, a 1980 television commercial broadcast in Australia for Prime Computers showed Baker and Ward romancing each other, in character as The Doctor and Romana, with the commercial ending with The Doctor (prompted by the computer) proposing marriage. These commercials are not, of course, part of the regular series continuity.
   In some of the voice overs on Peter Davison's DVDs the matter of physically expressed sexual attention is discussed. Accoring to Peter Davison and Matthew Waterhouse (Adric) John Nathan-Turner had very strict rules laid down about how the companions were allowed to physically interact with the Doctor and Adric was allowed more physical contact than the female companions because he was male and thus less likely to be romantically attracted . It is clear Nathan-Turner had a deliberate policy of not portraying the Doctor as a sexual being by avoiding physical contact though whether this was his decision or an explict/implict management directive is a matter of conjecture.
   The perception of the Doctor as essentially an asexual character, uninterested in romance, is why some portions of fandom reacted so strongly to the Eighth Doctor (Paul McGann) kissing Dr. Grace Holloway in the 1996 television movie, breaking the series' long-standing taboo against the Doctor having any romantic involvement with his companions.

Spin-off passion

However, the spin-off media both before and after the television movie have toyed with the idea in various ways. In the 1995 Virgin New Adventures novel Human Nature by Paul Cornell, the Seventh Doctor takes on the human guise of "Dr John Smith" and has a romance with a school nurse in 1913, albeit as a means to understand the human condition and with the Doctor's own memories as a Time Lord suppressed. The concluding chapter of The Dying Days, an Eighth Doctor novel by Lance Parkin, strongly implies intimacy occurring between the Doctor and Bernice Summerfield. In the Virgin novel Death and Diplomacy, by Dave Stone, the Seventh Doctor implies that he intentionally creates an image of asexuality to keep things simple.
   In various novels — especially Lungbarrow — it's also established that Time Lords don't reproduce sexually, but emerge from genetic Looms fully grown, although in equivocal fashion the same book also hints that the Doctor's birth was an exception. This idea was brought to the forefront in the '96 movie, where the Doctor states he's "half-human, on [his] mother's side", suggesting he'd a normal human birth, rather than a synthetic Gallifreyan one. Madame de Pompadour's reference to the Doctor's lonely childhood in "The Girl in the Fireplace" would also seem to contradict the Loom theory. The 2007 episode "The Sound of Drums" also directly contradicts this, with Gallifreyan children leaving for the academy when they reach the age of 8. This episode also shows a young Master.
   The classic series also made occasional references to the Doctor's childhood on Gallifrey (The Time Monster, State of Decay and Black Orchid), and there had been the occasional reference to Gallifreyan children, also referred to as "Time Tots" by Romana in the audio adventure Zagreus and the incomplete 1979 serial Shada.
   In the Big Finish Productions audio play Loups-Garoux, the Fifth Doctor reluctantly agrees to marry the werewolf Ileana De Santos and although he gets out of it later there is, as in Cameca's case, a degree of mutual attraction present. In the plays involving the Eighth Doctor, his companion Charley confesses her romantic feelings for him in Zagreus, but although he admits he loves her back at the time, it's a highly dramatic moment and the relationship doesn't progress beyond the platonic.
   The recurring novel and audio character Iris Wildthyme, created by Paul Magrs, is first introduced in the Short Trips story Old Flames, is a past romantic interest of the Doctor's who continues to flirt with him whenever they meet. In the audios Iris is played by Katy Manning, the actress who had formerly played Jo Grant during the Third Doctor's era. More of the Doctor's past relationships are explored in The Infinity Doctors and Cold Fusion.
   The question of romance is sometimes side-stepped with plot devices in the spin-off media. In the 2001 BBC Books novel Father Time by Lance Parkin, the Doctor adopts an orphaned Gallifreyan-like alien called Miranda. It is implied in the book that Miranda is actually the daughter of the Doctor himself from the far future. Miranda returns in the novel Sometime Never... by Justin Richards, with her own daughter Zezanne. At that novel's end, a time-active being called Soul travels into the past accompanied by Zezanne, the two believing themselves to be the Doctor and Susan, respectively.

Modern-day romance

The 2005 series played with the idea of a romantic relationship between the Ninth Doctor and Rose Tyler, with many characters assuming they were a couple (although they always both denied it), and Rose's boyfriend Mickey Smith clearly viewing the Doctor as a romantic rival for whom Rose has, in some sense at least, left him. Both showed flashes of jealousy when the other flirted with other characters.
   In the finale for that season, "The Parting of the Ways", the Doctor even kissed Rose (although the kiss also served a plot purpose). In the same episode, the Doctor's pansexual male companion Jack Harkness kisses both the Doctor and Rose in what he believes is a last goodbye. In the New Series Adventures novel Only Human by Gareth Roberts, Rose asks the Doctor how he'd know that marrying for love is overrated, to which he cryptically answers, "Who says I don't? You ask the Lady Mary Wortley Montagu." In a December 2005 interview on BBC Four, actor David Tennant, who had just taken the role of the Tenth Doctor, described the relationship between the Doctor and Rose as "basically a love story without the shagging".
   In the 2006 series, the Doctor and Rose kiss in "New Earth", but Rose is possessed by Cassandra at the time. In "School Reunion", the arrival of the Doctor's previous companion Sarah Jane Smith and his reaction to seeing her again prompts jealousy and worry from Rose, and Sarah all but admits that she's long been in love with the Doctor. In the same episode, the Doctor hints at deeper feelings for his companions when he remarks that humans wither and die, and it's hard to watch that "happen to someone who you..." but leaves the rest unsaid. In the following episode, "The Girl in the Fireplace" (written by Steven Moffat), the Doctor shares a passionate kiss and a strong romantic connection with Madame de Pompadour, who takes him away to "dance", but how far the metaphor (coined in the episode "The Doctor Dances") is taken isn't seen on screen. Although Rose doesn't seem to exhibit jealousy towards Madame de Pompadour, she does show some jealousy with regards to a woman called Lucy whom the Doctor speaks kindly of in the next episode, "Rise of the Cybermen". In the novel The Stone Rose, by Jacqueline Rayner, the Doctor kisses Rose after she saves him from being petrified, although it's described as "a kiss of gratitude and joy and unspeakable pleasure at being alive."
   In "The Impossible Planet" the Doctor and Rose share an awkward moment when they've to consider settling down in one time period and Rose suggests they do so together, and she later plants a kiss for good luck on the Doctor's spacesuit prior to his descent into the pit. In "The Satan Pit" the Doctor tells Ida Scott that Rose already knows how he feels about her, saying "If you see Rose, tell her...tell her...oh, she knows". In "Doomsday", when the Doctor says his goodbyes to Rose, she finally tells him that she loves him. He begins to reply, but only gets as far as saying her name before he gets cut off, and the next scene shows him standing silently alone, a single tear down his cheek, whatever words he'd intended to say remaining unspoken. In the audio commentary for the episode, executive producer Julie Gardner had stated that she thought "he absolutely was going to say it...he was going to tell her he loved her."
   In "Smith and Jones", the Doctor says that he'd rather 'be alone'. He kisses his new companion, Martha Jones, but only as a "genetic transfer" to distract their pursuers and he's extremely alarmed when she attempts to flirt with him on the TARDIS. The Doctor tells Martha that he and Rose "were together", and is clearly upset over losing her, although Martha points out that it was the Doctor who initiated their kiss and that he chose to take her away in the TARDIS (and moreover, she states that she 'only goes for humans', albeit to hide her disappointment).
   Later, in "Daleks in Manhattan", Martha confesses to Tallulah that she's attracted to the Doctor (though Tallulah euphemistically guesses that the Doctor is "into musical theatre", implying that she believes the Doctor is gay). In "Human Nature", as in the original novel, the Doctor's human self, John Smith, falls in love with Joan Redfern (now a nurse, rather than a science teacher) and Martha notes that the Doctor 'had to fall in love with a human' other than herself. When the Doctor is himself again at the end of "The Family of Blood" — during which Martha admits, in an attempt to convince Smith to change back to being the Doctor, that "he is everything to me, and he doesn't even look at me, but I don't care, because I love him to bits, and I hope to God he won't remember me saying this" — he tells Joan he's capable of everything that Smith was, but she rejects his attempt to establish a relationship with her as the Doctor.
   In the following episode, "Blink", he refers to being "rubbish at weddings, especially my own".
   In the penultimate 2007 series episode "The Sound of Drums", Martha shares a wordless moment with Captain Jack in which her attraction to the Doctor is suggested, to which Captain Jack replies, "You too?" Martha unambiguously states in the season finale, "Last of the Time Lords" that she's in love with the Doctor and ultimately chooses to leave him as he seems unable or unwilling to reciprocate.
   In the 2008 series many characters assume the Doctor and Donna to be a couple (apart from Agatha Christie in The Unicorn and the Wasp who notices that they've no wedding rings), the pair of them always strongly deny this anyway, to the point of it being a running gag. This makes Donna the first companion of the new series - apart from the short-lived Adam and Mickey - to not have a romantic interest in the Doctor. However, in The Unicorn and the Wasp, the Doctor had poison in his drink and had been poisoned. After insulating loads of items he needed to take it o
