The Doctor
The Doctor, sometimes known as Doctor Who, is the protagonist of the long-running BBC science fiction television series Doctor Who. An extraterrestrial Time Lord, the Doctor travels the universe in a time travelling spaceship called the TARDIS, often with companions. Since the show's inception in 1963, the character has been portrayed by fourteen lead actors. The transition to each succeeding actor is explained within the show's narrative through the plot device of regeneration, a biological function of Time Lords that allows a change of cellular structure and appearance with recovery following a mortal injury.
A number of other actors have played the character in stage and audio plays, as well as in various film and television productions. The Doctor has also been featured in films and a vast range of spin-off novels, audio dramas and comic strips.
Ncuti Gatwa most recently portrayed the Fifteenth Doctor from "The Giggle" up to "The Reality War".
Character biography
The Doctor is a Time Lord who travels through time and space in a dimensionally transcendental – "bigger on the inside" – time machine: the TARDIS. This time machine, whose name is an acronym for Time And Relative Dimension In Space, takes the exterior form of a 1963 police telephone call box and retains the appearance throughout the programme. Human companions accompany the Doctor through their adventures and serve as audience surrogate characters to ask questions which allow the Doctor to provide relevant exposition."Doctor" is a self-selected alias. In episodes specifically under showrunner Steven Moffat, the story arcs surrounding events in the Doctor's future implied serious consequences in the event of the Doctor's true name being spoken, with the nature of these finally revealed in "The Time of the Doctor". Spin-off media offer the explanation that the Doctor's true name is unpronounceable by humans. In "The Name of the Doctor", the Eleventh Doctor tells companion Clara Oswald that the name "Doctor" is essentially a promise he made. The promise itself is revealed in "The Day of the Doctor": "Never cruel nor cowardly. Never give up. Never give in."
Early life
The episode "The Timeless Children" revised the Doctor's origins, revealing a scientist and space explorer named Tecteun who found a lone, mysterious child with a supernatural physiology – one not belonging to any other life form or species – and an immense intelligence. She adopted the child and studied her, successfully grafting her regeneration capacity into her own species, the Shobogans, and herself. This species, who would eventually become the Time Lords, was restricted to a limit of twelve regenerations by a later incarnation of Tecteun. Tecteun and their child were eventually inducted into a clandestine Time Lord organisation known as the Division. After an unknown amount of regenerations, Tecteun's child began calling themself "Doctor". The Fugitive Doctor, true to her title, was on the run from the Division in a TARDIS disguised as a police box. The details of their life were also redacted from the Matrix – only snippets remaining, masked as the story of the Irish Garda Brendan. The true origins of the Time Lords remained hidden from themselves and from the Doctor.The First Doctor's subsequent childhood on Gallifrey has been little described in the series. In "Hell Bent" the Doctor recalled his origins as a high-born Gallifreyan. In The Time Monster, the Doctor says he grew up in a house on a mountainside and talks about a hermit who lived under a tree behind the house and inspired the Doctor when he was depressed. He is later reunited with this former mentor, now on Earth posing as the abbot K'anpo Rimpoche, in Planet of the Spiders. In "The Girl in the Fireplace", according to Madame de Pompadour who psychically linked with the Doctor's memories, the Doctor experienced a very lonely childhood. An elderly woman on Gallifrey died and was shrouded in veils and surrounded by flies, giving the Doctor recurring nightmares, which the confession dial in "Heaven Sent" would later visualise to torment him. In "Listen", it is ambiguously revealed the Doctor as a child often slept alone in a barn in the Drylands, was withdrawn from other children, and was cared for by guardian figures who privately doubted the child's ability as an eventual Time Lord. Through the dialogue, it is suggested that several Gallifreyan children were pressured into joining the army, a path which did not sit right with the Doctor's pacifist beliefs, and as a result he wished to enroll into the Time Lord Academy instead.
The classic series refers to his time at the academy and his affiliation with the notoriously devious Prydonian chapter of Time Lords. In "The Sound of Drums", the Doctor describes an academy initiation where, at the age of eight, Gallifreyan children were taken from their families and made to look into the Untempered Schism, a gap in the fabric of reality, to view the Time Vortex. According to the Doctor, when regarding the effects of the initiation on participants: "Some would be inspired, some would run away and some would go mad". When asked to which group he belonged, he replied, "Oh, the ones that ran away. I never stopped!" The Doctor was taught by future Lord President Borusa and Azmael, where he met Drax, with whom he attended a Tech course as part of the class of '92. In The Armageddon Factor, it is revealed that the Doctor scraped through the academy with 51% on his second attempt. In The Time Meddler, it is said that the Doctor was fifty years before the Meddling Monk. In Time and the Rani, the Doctor claims to have attended university alongside the Rani, specialising in thermodynamics.
At the academy, he met his childhood friend the Master and the pair grew up together. In "The End of Time", the Master recollects their childhood together where they would run all day across his father's field, described as 'pastures of red grass stretching far across the slopes of Mount Perdition' and the boys would call up at the sky. In "World Enough and Time", the Doctor claims that they both made a special pact where together they would visit every star in the universe; however, the Master was 'too busy burning them'. In "Hell Bent", one day at the academy, the Doctor found himself lost inside the Cloisters and spent four days inside. He was contacted by a Wraith who told him about the prophecy of a legendary creature known as 'the Hybrid', prophesied to have been crossbred from two warrior races that would stand in the ruins of Gallifrey, unravel the Web of Time and burn a billion hearts to heal its own. The Wraiths then revealed to him the secret passage leading to another side of the city. The last anyone heard from him was that he apparently stole the moon and the President's wife; however, this was revealed to have been a lie spread about by the Shobogans when in reality it was the President's daughter and he lost the moon. This event had a massive impact on the Doctor, who theorized that he himself was possibly the Hybrid. This is one reason the Doctor has stated as to why he decided to leave Gallifrey – out of fear. He has given convoluted and contradictory reasons as to why he left, for many reasons such as because his life path was pre-determined from his hidden previous life.
The Doctor stole a TARDIS with his granddaughter Susan from a repair shop on Gallifrey. In later episodes, the Doctor mentions that he once took a driving test to pilot a TARDIS and failed, and that he threw the instruction manual in a supernova because he disagreed with it. In "The Doctor's Wife", Idris mentions that the Doctor had been travelling with her for 700 years, which indicates that he would have been 200 years old when he first borrowed her. In "Twice Upon a Time", it is revealed that the Doctor also left to investigate the mystery of why good prevails in a universe where evil would seem to have so many advantages. It would be after his encounter with the Twelfth Doctor that the First Doctor realised that his actions made the difference in the balance between good and evil, with the Twelfth Doctor stating "The universe generally fails to be a fairy tale, but that's where we come in."
In other media, more has been revealed of the Doctor's early life. In the Past Doctor Adventures novel Divided Loyalties, the Doctor recalls his Academy years in a dream induced by the Celestial Toymaker. According to this, he was a member of an organisation called the Deca, ten brilliant Academy students campaigning for increased Time Lord intervention, alongside Mortimus, Ushas, Koschei, Magnus, Drax, a spy named Vansell, Millennia, Rallon and Jelpax. With this group, he learns about the Celestial Toymaker and travels to his realm in a type 18 TARDIS with Deca members Rallon and Millennia, who are killed. This leads to the Doctor's expulsion from the academy, condemned to five hundred years in Records and Traffic Control. In The Quantum Archangel, it is revealed the Doctor studied cosmic science alongside the Master, taught by Cardinal Sendok. In the Virgin Missing Adventures novel Goth Opera, it is said the Doctor was a frequent prankster while at the academy, introducing cats into Gallifrey's ecosystem with his friend Ruath and electrifying a "perigosto stick" belonging to his teacher, Borusa.
Feeling that too much of the Doctor's backstory had been revealed by the Seventh Doctor's era, writers Andrew Cartmel, Ben Aaronovitch and Marc Platt developed a new direction for the series. Cartmel wished to restore the character's "awe, mystery and strength" and make him "once again more than a mere chump of a Time Lord" – an idea the media dubbed the "Cartmel Masterplan". Under Cartmel, the show foreshadowed this concept; however, its 1989 cancellation meant that it was never realised onscreen. The proposed backstory was fully explored in Platt's 1997 novel Lungbarrow, where the Doctor is revealed as "the Other", a mysterious figure in Gallifreyan lore who co-founded Time Lord society with Rassilon and Omega. After a curse renders Gallifrey sterile, the Other devises biotechnological looms to "weave" new Time Lords; his granddaughter Susan is Gallifrey's last natural child. To escape a civil war with Rassilon, the Other throws himself into the loom system, where he is disintegrated and later woven into the Doctor. The Timeless Child reveal partly took inspiration from this.
