Tenth Doctor

"I'm the Doctor. I'm a Time Lord. I'm from the planet Gallifrey in the constellation of Kasterborous. I'm 903 years old, and I'm the man who's gonna save your lives and all six billion people on the planet below. You got a problem with that?"

- The Doctor

The Tenth Doctor is the latest known incarnation of the Time Lord known as the Doctor.

Regeneration
When the Doctor absorbed the Time Vortex from his companion, Rose Tyler, the forces contained in himself began to destroy every cell in his body. He regenerated for a ninth time to save his life. The Doctor immediately de-materialized the TARDIS from its location on Satellite 5, leaving the now-immortal Captain Jack Harkness (made so by the Bad Wolf) behind. (DW: The Parting of the Ways). (The Doctor would later say that the presence of such an un-natural being as Jack caused a form of instinctive distress. (DW: Utopia)) The Doctor piloted the ship back to Powell Estate in London on Christmas Eve 2006 and lapsed into a comatose state, but snapped out of it briefly and then for a longer time in order to beat back an invasion of planet Earth by the Sycorax on Christmas morning. During this adventure he had his hand cut off while in a sword fight with the Sycorax leader but, still retaining enough cellular energy from his regeneration, grew it back. (DW: The Christmas Invasion).

Adventures with Rose
The Doctor and Rose embarked on adventures together through time and space. Their first publicized adventure together was when they went to New Earth. They were summoned to the New New York hospital, where the Doctor toppled the regime that the Sisters of Plenitude had developed, creating humans and infecting them with every disease in the world to find cures. During this time, he also encountered Cassandra, who he'd met before in The End of the World and believed to be dead. She had possessed Rose's body, but he eventually convinced her to "end it." During a trip to 1879 Scotland, he and Rose stopped a werewolf from biting Queen Victoria and starting The Empire of the Wolf. As a reward, he was knighted as Sir Doctor of TARDIS and Rose was knighted as Dame Rose of the Powell Estate. They were then banished from the British Empire, since their blase attitude to danger unnerved the Queen. The Doctor also inadvertently inspired Queen Victoria to found the Torchwood Institute. (DW: Tooth and Claw). Back on 21st century Earth, the Doctor went undercover as John Smith, a physics teacher at a school which the Krillitanes had infiltrated. The Doctor had a chance reunion with his old friends Sarah Jane Smith and K-9. He also allowed Mickey Smith to accompany him at Sarah Jane's suggestion. (DW: School Reunion)

The Doctor met Reinette (also known as Madame de Pompadour) a beautiful noblewoman living in 18th century Versailles and saved her from the Clockwork Droids. They were connected by a fireplace on board the SS Madame De Pompadour. (DW: The Girl in the Fireplace)

On a parallel Earth, he witnessed the birth of that universe's Cybermen and saw off Mickey, who decided to stay on the other world. (DW: Rise of the Cybermen/The Age of Steel)The Doctor and Rose then went to see an Elvis concert, but accidentally ended up in England, just in time to witness the Queen's Coronation. Beforehand, though, the Doctor defeated the Wire, a being which stole victims' faces when they were watching television. The Doctor and Rose then ended up on the planet Krop Tor, orbiting a black hole. The Doctor, along with a researcher, Ida, went exploring underground, where they discovered a pit, into which the Doctor descended. Once he'd reached the bottom, he found himself face to face with the Beast, which had been terrorizing the explorers up above and possessing their servants, the Ood, as well as a crew member, Toby Zed. The Doctor trapped the Beast by imprisoning it in the black hole and was reunited with Rose and the TARDIS. Some time later, he and Rose defeated an Abzorbaloff, who had infiltrated LINDA, a social group who were trying to find the Doctor. He and Rose then went to 2012 to see the London Olympics. He met a girl called Chloe who had been possessed by a lone Isolus and was trapping people in drawings to stop the Isolus from feeling lonely. After briefly being trapped in a drawing himself, along with the TARDIS, the Doctor carried the Olympic torch to the stadium and then reunited with Rose. While watching the firework display, When the Doctor and Rose returned to present-day London, they found that the entire planet was being plagued by ghosts. He tracked the signal to Torchwood Tower and was subsequently kept prisoner by the Torchwood Institute who considered the Doctor their enemy. He strongly opposed their use of "ghost shifts" for power, since it was ripping open a hole between parallel worlds. After the computer technicians (who were under the control of Cybermen) restarted the ghost shift, he realised that the ghosts were Cybermen, coming through from the parallel world where he'd left Mickey. As the Cyberman invasion of Earth began, downstairs, a Void Ship that he'd examined earlier, opened, revealing Daleks led by the Cult of Skaro. When the Cybermen went downstairs to investigate the disturbance, he was visibly shocked to see the Daleks. He was also horrified to discover the Daleks had possession of a Time Lord prisoner ship, which they referred to as a Genesis ark, which contained millions of Daleks. In order to exile the Daleks and Cybermen to the Void, he had to open it, which would suck anything covered in "Void stuff" into the Void. However, realizing that Rose and the others were also covered in Void stuff, he sent her to the parallel world, along with Mickey, Pete Tyler and her mother, where she would be safe. But she returned, refusing to leave him. Together, they opened the Void and the Daleks and Cybermen got sucked into the Void. The plan initially went smoothly, but Rose's lever malfunctioned, threatening to abort the process. She managed to fix it but couldn't hold on and was nearly sucked into the Void, much to the Doctor's terror and despair, but was saved by her father and taken back across to the parallel universe, forever separating her from the Doctor. They met one last time on Bad Wolf Bay in Norway, where he was projecting himself through the last little gap between the universes, giving them a couple of minutes to talk. Rose told him she was working for this Earth's Torchwood and that her mother was three months pregnant. The Doctor told her that she'd been declared dead back in his world since she had gone missing after The Battle of Canary Wharf. Rose then broke down in tears and told him she loved him. He began to reply, getting as far as "And, I suppose... if it's my last chance to say it... Rose Tyler..." before fading away. (DW: Army of Ghosts/ Doomsday'') Rose ran into her mother's arms and the Doctor was left alone in the TARDIS, a single tear streaming down his cheek.

Life after Rose and Adventures with Martha
While he was grieving over Rose, a bride named Donna Noble, to his shock, appeared inside the TARDIS during her wedding ceremony. The Doctor discovered the involvement of the ancient Racnoss. After their destruction by the Doctor, and largely because of the Doctor's ruthless treatment of them, Donna decided not to travel with him. (DW: The Runaway Bride)

The Doctor met Martha Jones, a London medical student, and, after defeating a Plasmavore on the Moon, invited her along to travel with him in the TARDIS. (DW: Smith and Jones) On New Earth, which he had previously visited with Rose, he heard the final words of the Face of Boe to him: You are not alone. (DW: Gridlock) In 1930 New York City, the Doctor once more met and defeated the Cult of Skaro. (DW: Daleks in Manhattan) Dalek Caan survived. (DW: Evolution of the Daleks)



The Doctor hid from the Family of Blood by using a Chameleon Arch to transform himself mentally and physically into a Human schoolteacher called John Smith. He fell in love with a woman, Joan Redfern and would have spent the rest of his life with her. The Doctor was forced to retake his Time Lord body, and sought suitable punishment for the Family of Blood. (DW: Human Nature/The Family of Blood'')

Return of the Master
In Cardiff, where the Doctor had gone to "re-fuel" the TARDIS using the Cardiff rift, Captain Jack Harkness jumped onto and physically clung to the exterior of the TARDIS, hitching a ride to the planet Malcassairo in the far distant future. On Malcassairo, the Doctor found Professor Yana, actually his old nemesis; The Master, turned Human by another chameleon arch. The Master escaped using the Doctor's own TARDIS. (DW: Utopia)

Using the human name Harold Saxon, the Master made himself Prime Minister of Great Britain and invited in an army to take over the world. (DW: The Sound of Drums) The Master imprisoned the Doctor for a year, during the end of which time, he used his laser screwdriver to artificially age the Doctor 900 years, turning him into a small creature. The Master was later defeated by manipulation of the Master's Archangel Network to the Doctor's own advantage. The Doctor displayed great powers during this period, using the psychic energy to restore himself and manipulating it to grant him almost god-like powers. After disarming the Master with the telekinesis he acquired from the energy, it seemed to either dissipate or the Doctor released it. The Doctor then approached the Master and said the words the Master has been afraid to hear him speak: "I forgive you." The Master was shot soon afterwards by his human companion Lucy. Shortly after the Doctor made the decision to rehabilitate him as a prisoner aboard the TARDIS. The Master refused to regenerate and dies one last time in the Doctor's arms, thus leaving the Doctor to be truly the last Time Lord in existence, which left him grief-stricken, since he was narrowed down to be the entire Time Lord species. Interestingly, as the scene at the masters funeral pyre fades, a ring drops from the fire and is picked up by a female hand. Her laughter can be heard above the music. Shortly there after, Martha left him, thinking that she should go off and live her own life, though they parted amicably. (DW: Last of the Time Lords)

(DW: Time Crash) Shortly afterwards, he made a new friend, Astrid Peth, on board an alien spacecraft, the Titanic (modeled after the Earth original) but, just managing to save her before her death, could only save her by transforming her into a being of light. (DW: Voyage of the Damned)

A new partner in Donna Noble
"That's how I see the universe. Every waking second, I can see: what is, what was, what could be, what must not. That's the burden of a Time Lord, Donna. And I'm the only one left."

- The Doctor.

While investigating Adipose Industries, the Doctor was reunited with Donna Noble, who finally accepted his invitation to travel with him. She was quick to rule out the possibility of a romantic involvement, making their companionship a different experience than the Doctor had experienced with Rose and Martha. (DW: Partners in Crime)

During their travels, the Doctor realized he was responsible for the eruption of Mount Vesuvius and the destruction of Pompeii, in order to avert world domination by the Pyroviles. (DW: The Fires of Pompeii) He also helped set free the enslaved Ood of the Second Great and Bountiful Human Empire, (DW: Planet of the Ood) and disrupted a Sontaran stratagem on Earth, during which time he was reunited with Martha Jones. (DW: The Sontaran Stratagem)

One of the most important events in the Doctor's life came when the TARDIS transported he, Donna and Martha to Messaline, where his DNA was replicated to produce Jenny his daughter. Initially critical of the girl, the Doctor came to love his daughter, and mourned her death at the hands of General Cobb. He overcame his desire for revenge, however, in order to help found a new society on the planet. (DW: The Doctor's Daughter) Another important woman in the Doctor's life was introduced to him in The Library: Professor River Song, who claimed to know the Doctor from a point in his future. (DW: Silence in the Library) She was the only person to know his name, as she revealed prior to sacrificing herself to save the Data Ghosts trapped in the Library's core. The Doctor, inspired by Song's faith in him, was able to save River, preserving her in the core's virtual reality. (DW: Forest of the Dead) Shortly afterwards he and Donna visited the leisure planet Midnight. Donna stayed at the leisure palace as the Doctor takes a four-hour shuttle bus ride to the Sapphire Waterfall. The bus was then attacked by an unknown creature which possesses another passenger, Sky Silvestry and eventually the Doctor. His voice is stolen but he gets it back.(DW: Midnight) Next, the Doctor and Donna visit the Chinese-influenced planet of Shan Shen. Donna goes to get her fortune told but actually creates an alternate universe where she never met the Doctor. In this alternate universe she meets Rose who tells her two words to tell the Doctor. After Donna corrects the universe and is back in the fortune teller's tent her memory of the alternate universe begins to fade. The Doctor says that one of the Trickster's Brigade caused Donna to change the universe. Donna then tells the Doctor the two words: Bad Wolf. Donna asks what it means and the Doctor replies with The end of the Universe. (DW: Turn Left)

Rose Returns
After finding out that Rose was in Donna's parallel universe in Turn Left he rushed back to Earth to check that everything was OK and if she was there. When he went back into the TARDIS with Donna, the whole Earth began to shake and when he opened the doors they were orbiting in space. Finding no clue as to where the Earth was he went to the Shadow Proclamation and figured that 27 planets were stolen and nearby to where the Earth was. With a bit of help from Harriet Jones, Captain Jack Harkness, Sarah Jane Smith, Luke Smith, Martha Jones, Mr Smith and Rose Tyler as well as Donna's mother and grandfather he was able to be contacted and managed to lock on to the location of the Earth. After a quick chat with his friends and Davros he landed on Earth. While talking to Donna, Donna pointed out that Rose was behind him. He turned around and the two began to run towards each other. Then a Dalek emerged from the shadows and fired at him. It was only a glancing blow but was enough to mortally wound him. He had to be taken back into the TARDIS where he (apparently) began to regenerate. (DW: The Stolen Earth).

Using his nearby severed hand, he used the regeneration to heal himself, but not to regenerate into a new form. He and his companions ended up having to face off with the Daleks and thanks to the new Doctor (see human Doctor ), born from his severed hand and the power left by the regeneration, and Donna who was accidentally made part-Time Lord, the Daleks were defeated. However, he was horrified by the actions of the new Doctor, who wiped out the last remaining members of the Dalek race. He knew that the new Doctor was what he had once been like and decided to leave him on the parallel earth known as Pete's World to be with Rose. As a pure Time Lord and ever the self sacrificing hero, he was unable to say what he felt and would have said to Rose during the events of Doomsday. Though it broke his heart to do so, he knew that the new part human version of himself could give Rose what he could not, and that Rose was the only one who could make him better. The original Doctor then left Bad Wolf Bay, knowing that while painful for him, he in essence was finally able to get his girl.

Sadly, the tragedy continued as he was also forced to remove all memory of himself and anything he and Donna had done together as her Time Lord side started to overwhelm her human side. Upon bringing Donna home, he told her grandfather and mother that she must never be told what she had done and who she had been, as this would cause her death. The losses that day took a toll on the Doctor and once he left his best friend's house who could never know him again, he returned to traveling alone. The first three seasons had ended with him being distracted by an unexpected new event, but this time nothing arrives to stop him from simply feeling sad.

Personality
Like his predecessor, this Doctor was capable of boundless enthusiasm, though in his case often at inappropriate times. While many Doctors have intentionally flouted social conventions, the Tenth seems to be genuinely surprised when he is rude or uncouth. Charismatic and manic and with boundless energy, he retained and even exceeded his last incarnation's capacity for righteous anger, especially when Rose was threatened, as when the Wire stole her face. (DW: The Idiot's Lantern). When driven by anger or righteousness, he would act without hesitation to strike down those who opposed him; for example, he toppled the regime of Harriet Jones with just six well-chosen words after she committed what the Doctor considered mass murder (DW: The Christmas Invasion).

The Doctor also showed his anger when he gave each member of the Family of Blood an eternal punishment, fulfilling their wish for immortality in a twisted way (DW: The Family of Blood). While he had resolved much of the survivor's guilt felt previously, he is beginning to feel his age and, behind the outward playfulness, he feels a deep loneliness. His keen sense of loss leads him to empathise with those who have also suffered.

There was an undeniable shadow cast over the jollity of the Doctor. He had a ruthlessness, bordering on arrogance that was almost eerie to behold. Beneath his youthful veneer, the Doctor is a very old man who has seen many terrible things; and in some matters, his patience and capability for mercy has worn out or diminished. His usual jolly demeanor has somewhat disappeared since the departure of Rose. He was a little angrier, darker, and not as friendly towards Donna or Martha. This suggests that he never really got over Rose's leave-taking.

After meeting Agatha Christie and witnessing the events that lead to her infamous disappearance and amnesia, the Doctor theorizes that what kept her writing all of the years that followed was a desire to remember the events she had forgotten and makes a notable comparison to that desire to his compulsion to travel. This subtle remark suggests that the reason the Doctor travels is because he is trying to recapture memories that he has lost or that were taken from him.

The tenth Doctor has a very hard time accepting defeat or failure, for example when he was unable to save Astrid he kicked a teleport, screaming "I can do anything!" (Voyage of the Damned). Arguably this may be because he has seen so much destruction he feels driven to try to prevent it where possible, also River Song thought if he lost this trait the universe would become a darker place (Forest of the Dead). He frequently gets into trouble because of his vast and loose sense of superiority (Midnight) and provides his name (his chosen name, not his birth name) as a threat, which only rarely works, despite his apparent expectations (perhaps because so few species know of his existence). The tenth Doctor frequently ignores reproach; when companions point out he's committing horrible acts, he ignores them or changes the subject. The tenth Doctor seems quite comfortable committing mass murder in some cases, although this tendency lessens over time. In (Journey's End), he attributes this change to Rose Tyler, telling her she helped him get through the time in his life that was "full of blood and anger".

Habits and Quirks
The Doctor made frequent reference to twentieth century pop culture, from the Ghostbusters theme (DW: Army of Ghosts) to the song "Circle of Life" from The Lion King (DW: The Christmas Invasion). He had also read the Harry Potter books, saying that he cried after reading the seventh book (DW: The Shakespeare Code). He's fond of rock and roll, trying to take Rose to see concerts by both Elvis Presley (DW: The Idiot's Lantern) and Ian Dury (DW: Tooth and Claw), and dresses in the manner of an indie Brit-pop musician. He wore trainers and faux reading glasses — both deliberate homages to his fifth incarnation. (DW: Time Crash) He often remarks that exotic technology or life is "beautiful" and is genuinely enthralled by such discoveries, sometimes to the extent that he places himself or his companions in danger. When this Doctor is faced with an occurrence that dumbfounds him he says, "What?" repeatedly increasing the confused expression on his face each time (He has said this a total of 10 times). While attempting to explain something he'll often interrupt himself with a "Well..." and further elaborate what it was he was talking about (see DW: Blink for an example).

Until they left his life, he continued his previous incarnation's habit of mildly abusing both Mickey and Jackie, though generally in a more obviously playful fashion.

The Doctor is also fond of the phrase "I'm sorry, I'm so sorry". He has said the phrase a total of 10 times. Another favoured phrase is "Allons-y!" which he has used 9 times to date. He also often responds "I'm always all right" even when all evidence points to the contrary (a response which the Seventh Doctor also used to deflect the same question). He has also been known to often refer to things as brilliant.

The Doctor has a stated fondness for "little shops", the gift stores usually found in hospitals and other public places. (DW: New Earth, Smith and Jones, Silence in the Library)

This incarnation of the Doctor relies heavily upon his sonic screwdriver, pushing it to limits not seen in previous incarnations. Other tools he uses frequently include psychic paper and, incongruously since he is not a medical doctor, a stethoscope (although the Doctor's stethoscope appears to have additional abilities; for example he used it to assist his phone in receiving a signal from the relocated Earth (DW: The Stolen Earth). Like previous incarnations, he appears to have the ability to carry a large and diverse number of objects in his pockets,stating once in "The Runaway Bride" that they're similar to the TARDIS (Bigger on the inside) including at one point a wind-up mouse (DW: The Doctor's Daughter) He also follows the trend of his immediate successors in displaying increasing skill for using the TARDIS, on several occasions even using it in the form of a standard spaceship rather than simply dematerializing it every time. (DW: The Runaway Bride and Partners in Crime). He is told by a future companion that he will one day be able to command the TARDIS by a click of his fingers and initially believes this to be nonsense, but later finds out that he does possess such abilities (probably signifying an increasingly powerful telepathic connection between the TARDIS and himself) (DW: Forest of the Dead). He has taken to carrying a GSM cell phone with him and on (DW: The Stolen Earth) it is revealed that this number can be used to contact him anywhere in space and time. Like his previous incarnation did with Rose Tyler's "superphone", this incarnation has also taken to "upgrading" the mobile phones of his later companions in order to facilitate communication with their families and with the Doctor: both Martha Jones and Donna Noble's phones were so modified and, like Rose's mother, their close relatives were aware that they could communicate through time and space as a result (DW: The Stolen Earth). The phone he carries is Martha Jones' superphone, given to him by her so she could contact him if need be.

Appearance
The Doctor seemed disappointed that his tenth incarnation was not "ginger" (red-headed), but has worn his own dark brown hair in various ways throughout the series: unstyled in (DW: The Christmas Invasion), a fifties-style quiff in (DW: The Idiot's Lantern), and flattened forwards in (DW: The Runaway Bride).

He wears a dark brown (with blue pinstripes) or a blue (with red pinstripes) suit, a shirt and a tie (otherwise, open-shirted with a light grey t-shirt/vest (DW: Tooth and Claw), (DW: Planet of the Ood), a red-hued t-shirt (DW: 42) or a black t-shirt ((DW: Midnight), a light brown overcoat (which he claims was given to him by Janis Joplin), and a pair of trainers, in colours ranging from cream (brown suit), black (tuxedo) or burgundy (blue suit), a costume which Tennant described as "geek chic". The blue suit debuted in Series 3 episode 1, "Smith and Jones", and both suits were worn from his adventures with Martha Jones onwards, until the fourth series finale (DW: Journey's End) in which an identical Doctor donned the blue suit and was left in a parallel universe with (DW: Rose Tyler). According to an interview on Parkinson, David Tennant and Russell T Davies got the idea for the Tenth Doctor's costume from an outfit Jamie Oliver had worn on Parkinson just after David had taken the role. Another part of the Doctor's costume is a pair of dark tortoise-shell rectangular frame glasses; since The Christmas Invasion he has appeared to require them in numerous episodes. As noted above, the Tenth Doctor credited the (DW: Fifth Doctor) with inspiring his footwear and glasses, which he admits are "brainy specs" rather then being actually required.

Tenth Doctor's Companions

 * Rose Tyler
 * Mickey Smith
 * Donna Noble
 * Martha Jones
 * Captain Jack Harkness
 * Astrid Peth
 * Sarah-Jane Smith

In addition, River Song claimed to have been a companion from the Doctor's future. (DW: Silence in the Library/Forest of the Dead) Sarah Jane, previously a companion of the Doctor's 3rd and 4th incarnation, resumes her companion role during Davros' plot. (DW: Journey's End) Sarah Jane previously assisted the Tenth Doctor alongside K-9 Mark III investigating Deffry Vale High School. (DW: School Reunion)

To date there have been three intervals in which the Doctor is left without a companion and travelled on his own for an unknown length of time, or perhaps travelled with unchronicled companions: between Donna Noble's initial invitation to join the TARDIS and his first meeting with Martha (DW: The Runaway Bride and Smith and Jones); after dropping Bayldon Copper off on earth and his reunion with Donna (DW: Voyage of the Damned and Partners in Crime) and between the departure of Donna and his other companions and (at least) his encounter with the Cybermen (DW: Journey's End and the 2008 Christmas Special (title TBA)).

Trivia

 * The Tenth Doctor's Phone Number is 07700-900461.(Technically this is Martha's phone which she gave to the Doctor in DW:Last of the Time Lords) If this number is called, the caller hears a dead dial tone.
