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 is gonna save your lives and all 6 billion people on the planet below. You got a problem with that?"

The Tenth Doctor was the tenth incarnation of the Doctor. Unlike his immediate predecessor, who was plagued by melancholy due to his actions during the Last Great Time War, this Doctor was much more outgoing and genial, a demeanor that hid the "survivor's guilt" that had plagued him since the war. Throughout his his life, however, the weight became much more pronounced, haunted by companions lost, enemies believed long-dead and events that threatened the fabric of time itself. This Doctor tragically met his end after he absorbed a huge quantity of nuclear radiation while saving his companion Wilfred Mott.

Regeneration
"New teeth. That's weird."

When the Doctor absorbed the TARDIS' 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 dematerialised the TARDIS from its location on Satellite 5, intending to fulfill his promise to take Rose to the planet Barcelona in the year 5006. With Rose suffering an emotional crisis over the Doctor's sudden change, the Doctor instead takes pity and heads back to the Powell Estate in London on Christmas Eve 2005 after convincing her of his identity by reminding her of the very first thing he ever said to her. Before he could successfully complete the landing, he began to suffer adverse effects from the violence of his physical change and experienced manic hyperactivity, sending the TARDIS to such dangerous extremes of speed that it crash-landed. Shortly afterward, his memory took a turn for the worse and he dazedly wished Jackie and Mickey a Merry Christmas before promptly lapsing into a coma. He snapped out of it briefly in order to save Rose from a killer Christmas tree, but the stress of waking up too soon made matters worse, and he soon collapsed again. He eventually recovered in time to beat back an invasion of 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)



New Adventures with Rose
"We're good, you and me."

The Doctor and Rose embarked on adventures together through time and space. They came to New Earth and were summoned to the New New York Hospital by the Face of Boe. While there, he stopped the Sisters of Plenitude, who were creating Humans and infecting them with every disease. During this time, Rose was possessed by Cassandra, who was trying to extend her life, but the Doctor eventually convinced Cassandra to "end it." (DW: New Earth). Next they took a trip to 1879 Scotland. There the Doctor and Rose stopped a werewolf from biting Queen Victoria and starting The Empire of the Wolf. As a reward, the Doctor was knighted Sir Doctor of TARDIS and Rose was knighted Dame Rose of the Powell Estate. They were then banished from the British Empire, since their blasé attitude to danger unnerved the Queen. The Doctor also inadvertently inspired Queen Victoria to found the Torchwood Institute, dedicated to defending Britain from the alien threat. (DW: Tooth and Claw)

Back on 21st century Earth, the Doctor went undercover as John Smith, a physics teacher at a school which the Krillitane had infiltrated. The Doctor had a chance reunion with his past companions Sarah Jane Smith and K-9. The Doctor also allowed Mickey Smith to accompany him and Rose on their travels at Sarah Jane's suggestion. (DW: School Reunion)

The Doctor, Rose and Mickey next found themselves in a 51st century ship, which was connected to 18th century France. There he met a pre-teen Jeanne-Antoinette Poisson. The Doctor saved her as a child from the ship's Clockwork Droids and several more times in her life. After the droids were stopped, he offered to allow her to travel with him, but he made a mistake and returned to her after she died. (DW: The Girl in the Fireplace)

On a parallel Earth, the Doctor, Rose and Mickey witnessed the birth of that universe's Cybermen. The adventure ended with Mickey deciding to stay in the parallel universe, leaving Rose and the Doctor to continue their travels together. (DW: Rise of the Cybermen/The Age of Steel)

The Doctor and Rose planned to see an Elvis concert, donning the outfits of the 1950s and riding a scooter out of the TARDIS, however, they accidentally ended up in England, June 2, 1953, where The Wire was planning to steal the essences and faces of everyone watching the coronation on television. Rose fell victim to the Wire, but during the coronation the Doctor defeated the Wire, restoring the faces of its victims. (DW: The Idiot's Lantern)

The Doctor and Rose then travelled to the planet of Krop Tor, an impossible planet that orbited a black hole and inhabited by Sanctuary Base 6. The Humans of Sanctuary Base 6 had journeyed to Krop Tor to discover the source of power emanating from the planet's core, which was allowing the planet to orbit a black hole without falling in. The Doctor and a researcher from the crew of Sanctuary Base 6 named Ida Scott descended into the core of the planet to explore. There they discovered a pit, into which the Doctor went, alone. It is at this point that we first see his love for Rose, when he says to Ida before he drops into the pit, 'tell Rose I... oh she knows.' Once he'd reached the bottom, he found himself face-to-face with the Beast. The Beast had been terrorizing the explorers on the surface and possessing their servants, the Ood. The Doctor trapped the Beast by imprisoning it in the black hole and was joyfully reunited with Rose and the TARDIS. (DW: The Impossible Planet/The Satan Pit) Some time later, he and Rose were in a fight with a Hoix, an event seen by Elton Pope. When Elton later offended Rose's mother, the Doctor and Rose confronted him, as well as helped him defeat the Abzorbaloff. (DW: Love & Monsters) He and Rose then travelled to 2012 to see the London Olympics. He met a girl named Chloe Webber who had been possessed by a lone Isolus. Chloe was trapping other children from her street in drawings to stop the Isolus from feeling lonely. After briefly being trapped in a drawing himself, along with the TARDIS, the Doctor ran with the Olympic torch to the stadium, lit the Olympic flame, and then reunited with Rose. (DW: Fear Her)

The Pain of Loss
"If it's my last chance to say it. Rose Tyler...-"

When the Doctor and Rose returned to present-day London, they found that the entire planet was being visited by beings believed to be ghosts. The Doctor tracked the signal to Torchwood Tower and was subsequently taken prisoner by the Torchwood Institute. He strongly opposed their use of "ghost shifts" for a power source, as it was ripping a hole between parallel worlds which increased in size with every "ghost shift". The original tear was caused by "The Sphere", an object the Doctor identified as a Void Ship. Later, three computer technicians (who were secretly under the control of Cybermen) restarted the ghost shift. This led to the realisation that the ghosts were actually Cybermen, coming through from the parallel world where the Doctor and Rose had left Mickey. As the Cyberman invasion of Earth began, the Void Ship opened, revealing the Cult of Skaro, a group of Daleks with a Genesis Ark. The Genesis Ark was Time Lord technology which contained millions of Daleks that had been imprisoned by the Time Lords.

In order to save both dimensions from annihilation and defeat the Daleks and Cybermen, the Doctor decided to open the Void. This opening would suck anything covered in "Void stuff" into it. Realising that himself, Rose and the others were also covered in Void stuff, the Doctor sent Rose, against her will, to the parallel world, along with Mickey, Pete Tyler and her mother, where they all would be safe from the Void. However, Rose returned, refusing to leave the Doctor and knowing that in making her choice she would never see her family again. Together, the Doctor and Rose opened the Void and the Daleks and Cybermen were sucked in. The plan initially went smoothly, until Rose's lever malfunctioned, threatening to halt the process. Rose managed to secure the lever but couldn't hold on and was almost sucked into the Void, much to the Doctor's terror and despair. Rose was saved at the last second by her parallel father and taken back across to the parallel universe, separating her from the Doctor. The Doctor and Rose were able to meet one last time on Dålig Ulv Stranden in Norway; the Doctor had parked the TARDIS in orbit around a supernova for enough power to project an image through the last gap between the universes to say goodbye. The Doctor had fallen in love with Rose and vice versa, and although Rose was able to confirm her own love, The Doctor was cut off before he could express his feelings. (DW: Army of Ghosts / Doomsday)

A Noble Encounter
"You're cooking!"

Whilst he was grieving over Rose, a bride named Donna Noble, to the Doctor's shock, appeared inside the TARDIS during her wedding ceremony. The Doctor discovered the involvement of the ancient Racnoss and defeated them. After the Doctor's destruction of the Racnoss, and largely because of the Doctor's merciless treatment of them, Donna decided not to travel with him and left after telling the Doctor to "find someone." (DW: The Runaway Bride)

An Old and Best Friend
Sometime after meeting Donna, the Doctor, travelling alone, landed on the Slough of the Disjointed Planets, an area of space populated by warlike races renowned for their brutal conflicts. There he encountered the dying War Keeper, the ancient controller of the population of the Disjointed Planets. In an attempt to find a worthy successor, the War Keeper scanned the Doctor's mind for the identity and location of the greatest leader of the cosmos, and chose Brigadier Lethbridge-Stewart. The old soldier, now retired and in his late 70s, found himself transported to the Slough to receive the position, but refused to accept the role. As an alternative, the War Keeper, using the Doctor's memories, choose as an alternative Mike Yates, but accidentally summoned to the Disointed Planets another, far less capable man with the same name. Rivals of the dying War Keeper infiltrated his helpers before his death and passed onto the other Mike Yates the Keeper's control device: the Warkeeper's Crown. With the weak-minded wrong-Yates under control of the Crown, and with wrong-Yates in turn in control of the numerous forces of the Disjointed Planets, the deceased War Keeper's rivals planned to control the conflicts. The controlled wrong-Yates transported himself back to his home on Earth, along with many orcs, hawks, and other creatures. The Doctor and the Brigadier, with an army of Brigadier-clones the Doctor created with technology at the Slough, returned to the Earth to defeat the demon hordes and free the wrong-Yates from the Crown's control. (During this time, the Mike Yates whom the Doctor and the Brigadier knew of old witnessed the conflict.) With the danger passed, the Doctor and the Brigadier, still and ever the best of friends, re-lived their old glories, and said their good-byes, although the Brigadier expected to see his old friend once more. (DWM: The Warkeeper's Crown)

Dr. Smith and Dr. Jones
"Travel all across the universe to ask me on a date"

The Doctor met Martha Jones, a London medical student, and, after defeating a Plasmavore on the Moon (DW: Smith and Jones), invited her to travel with him in the TARDIS. They arrived in Shakespearean London and foiled the Carrionites and discovered the mystery of Love's Labour's Won (DW: The Shakespeare Code). He then broadened Martha's trip to one to the past and one to the future after being chased out of the time. He next landed on New Earth, which he had previously visited with Rose, where he heard the final words of the Face of Boe: You are not alone. (DW: Gridlock) In 1930s New York City, the Doctor once again met and defeated the Cult of Skaro. (DW: Daleks in Manhattan)

Together they put an end to the work of mad Professor Lazarus (DW: The Lazarus Experiment) and following that helped save a spaceship from plummeting into a sun. Later, the Doctor hid from the Family of Blood, a family of aliens who wanted his Time Lord body, by using a Chameleon Arch to transform himself mentally and physically into a Human school teacher named John Smith, hiding completely his Time Lord self so that his alter ego had no recollection of the Doctor. John Smith subsequently fell in love, much to the disappointment of Martha, with the matron of the school, Joan Redfern and would have spent the rest of his life with her. However, the Doctor was forced to retake his Time Lord body to save the Earth from destruction, and sought suitable punishment for the Family of Blood. (DW: Human Nature / The Family of Blood)

The Doctor and Martha travelled to 2006 to investigate strange disappearances at an old abandoned house. They were transported back in time to 1969 by aliens in the form of stone angels who fed off their potential energy. Using information given to him by Sally Sparrow prior to the incident, he left messages for Sally in the future to bring the TARDIS back to 1969. (DW: Blink)

A Lord's Return
"I forgive you"

In Cardiff, where the Doctor had gone to "refuel" 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 extremely far distant future. On Malcassairo, the Doctor found Professor Yana, actually his most fearsome nemesis: The Master. The Master had been made human by another Chameleon Arch, but when Martha questioned his old fob watch, he opened it and became the Master again. After being shot by Professor Yana's assistant Chantho and facing imminent regeneration, the Master locked himself inside the Doctor's TARDIS and despite the pleas of his enemy, hijacked the ship and escaped, leaving the Doctor, Jack and Martha to die at the hands of the Futurekind. (DW: Utopia) They were able to escape to the present when the Doctor used his sonic screwdriver on Jack's broken Vortex Manipulator. (DW: The Sound of Drums)

Using the human name of Harold Saxon, the Master made himself Prime Minister of Great Britain and invited an army of Toclafane to invade the world. (DW: The Sound of Drums) The Master imprisoned the Doctor for a year, during 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 his Archangel Network to the Doctor's own advantage. The Doctor displayed great powers during this period, using the psychic energy of the Earth's people (having been told by Martha to think of the Doctor at a specific moment) to restore his youthful look and manipulating it to grant him almost god-like powers. After disarming the Master, he then approached the Master and spoke the words the Master was terrified to hear: "I forgive you." The Master was shot soon afterward by his human wife, Lucy Saxon, who sought revenge for his treatment of her. Subsequently, the Doctor decided to attempt to rehabilitate the Master, planning to keep him a prisoner aboard the TARDIS. At the thought of becoming the Doctor's captive, the Master refused to regenerate and died for, supposedly, the final time in the arms of the Doctor, thus leaving the Doctor truly the last Time Lord in existence.

Following the events of the Year That Never Was, Martha left the Doctor, believing that she needed to live her own life and be with her family. Her family had been tortured at the hands of the Master and Martha felt partly responsible for their suffering. Not only that but, almost from their first encounter, Martha had fallen in love with the Doctor; however, she knew that her love was unrequited and that he only saw Rose when he looked at her. Martha explained this to the Doctor and they parted amicably. (DW: Last of the Time Lords)

When Incarnations Meet
"you know what, Doctor? You were my Doctor."

Shortly after Martha left, the Doctor accidentally crashed his TARDIS with that of one of his earlier regenerations. He was able to use his memory of the event (from his Fifth regeneration's perspective) to separate the TARDISes, though he forgot to turn the shields back on and the spaceship Titanic crashed in through the walls. (DW: Time Crash)

A Titanic Adventure
"My Christmases are always like this!"

Deciding to join the party on board, the Doctor quickly made a new friend, Astrid Peth, on board Titanic. When the ship's owner, Max Capricorn, had Titanic purposely crashed into a meteor shower, the Doctor attempted to save the passengers, but could only save Astrid by transforming her into a being of light. The Doctor stopped the Titanic from crashing into Earth and left Mr. Copper on the planet. Following the incident, the Doctor set out on his own once again. (DW: Voyage of the Damned)

A Noble Reunion
"You just want to mate?!"

While investigating Adipose Industries, the Doctor was reunited with Donna Noble, who finally accepted his invitation to travel with him. The Doctor was quick to rule out the possibility of a romantic involvement, giving their companionship a different dynamic to that of the ones the Doctor had previously 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 invasion on Earth, during which time he was reunited with Martha Jones. (DW: The Sontaran Stratagem/The Poison Sky)

Directly following this, the TARDIS transported the Doctor, Donna and Martha to the planet Messaline in the far distant future, where his DNA was stolen and replicated to produce Jenny, his biological daughter. Initially critical of the girl due to her strong predilection for violence, 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)

Some time after this, the Doctor and Donna visit 1926 and meet famed author Agatha Christie, and become embroiled in a murder mystery, ultimately saving her from a Vespiform, which results in Agatha losing some of her memories. (DW: The Unicorn and the Wasp)

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 distant point in his future. (DW: Silence in the Library) She displayed knowledge of the Doctor's real name, as she revealed prior to sacrificing herself to save the Data Ghosts trapped in the Library's core. The Doctor, inspired by her faith in him, was able to save River Song by preserving her ghost in the core's virtual reality. (DW: Forest of the Dead)

Return of the Bad Wolf and Dealing with Davros
"The man who abhors violence, never carrying a gun. But this is the truth, Doctor. You take ordinary people and you fashion them into weapons. Behold your Children of Time transformed into murderers. I made the Daleks, Doctor. You made this."

Shortly afterward he and Donna visited the leisure planet Midnight. Donna stayed at the leisure palace whilst the Doctor took a four-hour shuttle bus ride to the Sapphire Waterfall. The bus was subsequently attacked by an unknown creature which possessed one of the passengers, Sky Silvestry and eventually the Doctor, with the aim of inciting mass hysteria among the other passengers. Before the creature could trick the passengers into throwing out the Doctor, Sky was dragged out into the X-Tonic sun by the bus' hostess, who realized that Sky was stealing the Doctor's voice, and the creature departed, its plans defeated. (DW: Midnight)

Next, the Doctor and Donna visited the Chinese-influenced planet of Shan Shen. When Donna went to get her fortune told, a member of the Trickster's Brigade created an alternate universe around her. In this alternate universe she met Rose Tyler, who told her two words to tell the Doctor. After Donna corrects the universe, she is able to tell 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)

He rushed back to Earth to check that everything was fine, but as soon as they went back to the TARDIS, the whole planet was stolen. Finding no clue as to where the Earth was, he went to the Shadow Proclamation and learned that 27 planets including Earth had been stolen. With a bit of help from Harriet Jones, Jack Harkness, Sarah Jane Smith, Luke Smith, Martha Jones, Mr Smith and Rose Tyler (The Children of Time) 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 (who had been saved by Dalek Caan from the Last Great Time War). 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 began to regenerate. Using his nearby severed hand, he used the regeneration to heal himself, but not to regenerate into a new form.

As a result of this, a new Doctor was born from his severed hand and Donna who was accidentally made part-Time Lord, becoming the DoctorDonna. DoctorDonna disabled the planet powered Reality Bomb to stop Davros from destroying the entire universe and then the Daleks and the three Doctor's sent the planets back to their original time and space. However, The Doctor was horrified by the actions of the new Doctor, who wiped out the last remaining members of the Dalek race. The Children of Time used the TARDIS to tow Earth back to its original point in time and space. The Doctor said his goodbyes to Sarah Jane, Martha, Jack and Mickey before he left the new Doctor in Pete's World, hoping that Rose and the new Doctor would be able to help each other. The new Doctor was able to tell Rose that he loved her and they passionately kissed. Upon returning to our universe, he was forced to remove Donna's Time Lord abilities, as they would eventually kill her. He returned Donna to her mother and grandfather, and told them that they would have to make sure she never remembered the Doctor. (DW: The Stolen Earth /Journey's End)

Invasion of the Mind
"Hello. We're the Doctor. From Gallifey. And we're very, very, unhappy"

Es'Cartress of the Tactire, an inhabitant of Callufrax Minor, had been stuck on the Crucible and was unable to return home before the Doctors returned the planets. As such, he had to escape to the TARDIS. He then attempted to take over the Doctor's mind, but his link with the TARDIS forced them both into the Matrix. The Doctor was shown to have the stronger mind and was able to take control, killing Es'Cartress. (IDW: The Forgotten)

The Two Doctors?
"Allon-sy!"

An unknown length of time after leaving Donna, the Doctor travelled to London, Christmas Eve 1851. The Doctor met a man calling himself 'the Doctor' and at first assumed him to be his future incarnation. In reality, he was a Human man, Jackson Lake, who had the contents of an Infostamp about the Doctor imprinted on his brain. Jackson and his companion Rosita Farisi aided the Doctor in stopping the plot of the Cybermen and their ally, Mercy Hartigan. London was saved, Lake was reunited with his son, and invited the Doctor to share Christmas dinner with his new family (an offer which was at first denied, then accepted by the Doctor). (DW: The Next Doctor)

An Easter Egg
"Oh the little dish is going round!"

Sometime later, the Doctor travelled to London in 2009 at Easter, investigating strange readings on a bus. While he investigated, the bus was hurtled through a portal and reappeared on San Helios. On the bus he met yet another one-off companion, Christina de Souza, and embarked on a mission with her (and UNIT on the end of a phone) to return the bus and its occupants to Earth and stop the Swarm from invading. At the end of this adventure, just before leaving in the TARDIS, the Doctor rejected Christina's offer of companionship, stating that he has lost anyone who travels with him and he'd swore never again. Carmen, a low level psychic who aided during the adventure told the Doctor these chilling words.


 * "Your song is ending sir, It is returning. It is returning through the dark, oh but then... He will knock four times"

When Christina (who was a jewel thief) was arrested, the Doctor used the sonic screwdriver to aid her escape in the bus. Finally, when the Doctor was about to be arrested for helping Christina, he entered the "police box" to "arrest himself" and left. (DW: Planet of the Dead)

Wedding Crasher
"You're so important, not just to me."

At some point when he was travelling alone the Doctor crashed Sarah Jane Smith's wedding. He knew The Trickster an old enemy of hers, would try and get his revenge on her after she had foiled the Trickster's previous attempts to cause chaos. Just as he got there, she and her future husband Peter Dalton were taken by the Trickster. He was teleported to a nether realm along with Rani, Luke and Clyde, whom he had heard all about from Sarah Jane. He fought the Trickster, who hinted about his next regeneration "The gate is waiting." The TARDIS gave Clyde the power to control Artron energy by mistake, so he could have defeated the Trickster, while the Doctor informed Sarah Jane what needed to be done. Peter, Sarah Jane's fiancé, sacrificed himself to destroy the Trickster, leaving Sarah Jane alone and heartbroken. When the world was put back to normal, the Doctor visited 13 Bannerman Road and let Sarah Jane and her friends look inside TARDIS, after which he said farewell while sincerely asking Sarah Jane to never forget him. (SJA: The Wedding of Sarah Jane Smith)

Life on Mars
"The Doctor. Doctor. Fun."

The Doctor, deciding to go to the planet Mars, met the crew of Bowie Base One, including Adelaide Brooke who served as his companion for a short time. He knew the crew of Bowie Base, and that everyone would die, as it was one of the most important events in the expansion of Humanity through the universe. He learnt that the crew died due to the Flood, which possessed six of them. Initially unwilling to interfere due to his belief that the event was a fixed point in time, he changed course once he remembered the deaths he had lived through and what it had left him with. He saved Adelaide, Mia and Yuri and took them back to Earth 2059. Adelaide was angry at the Doctor's interference, and scolded him for thinking himself above obeying history's course (her death meant that her granddaughter would be inspired to go explore the stars). Adelaide then walked into her home, apparently having given up trying to defy the Doctor, but committed suicide. The Doctor's memories of the day's events changed to fit in with the new timeline created. Distraught at the impossibility of his task of changing history, he began to ponder his own end when a vision of Ood Sigma appeared before him. As he entered the TARDIS, the Cloister Bell rang. With a defiant "No!" he activated the TARDIS. (DW: The Waters of Mars)

American Dream
"Howdy there partners!"

At some point after leaving 2059, the Doctor visited America, 1958. While there, he visited a diner, meeting Cassie Rice and Jimmy Stalkingwolf. The Doctor examined a piece of "space junk" from the Roswell Crash eleven years ago. He accidentally activated it, drawing the attention of the android Mister Dread. Escaping, the Doctor, Cassie and Jimmy were then attacked by a Viperox battle drone, which was promptly blown up by the United States military. The three were then taken to Area 51. They encountered Colonel Stark, who dismissed the Doctor's warnings about the Viperox, and attempted to have the Doctor and his companions mind-wiped. The attempt was unsuccessful, and the trio soon escaped, discovering a small grey alien along the way. They escaped to the town of Solitude and took shelter in a deserted building. Jimmy was then kidnapped by the Viperox, forcing the Doctor and Cassie to follow. They found Jimmy in the presence of a Viperox Queen before escaping into the desert, where they were confronted by four members of the Alliance of Shades who are destroyed by Jimmy's father, Night Eagle, who took them to Rivesh Mantilax, the husband of Seruba Velak, the grey alien captive in Area 51. Colonel Stark then captured them all and took them back to Area 51. They Doctor then ran off with the "space junk" - actually a weapon capable of destroying the Viperox. He was cornered on the roof by the Colonel, but convinced him to turn against the Viperox. The Viperox then invaded America but were beaten back by the Doctor. He departed soon after, leaving Cassie and Jimmy with a suggestion to start dating. (DW: Dreamland)

Final Farewell
"I don't want to go!"

After meeting with the Ood on their home planet, he learned of the Master's impending resurrection on Earth, and raced to stop it, only to arrive too late. After discovering the Master living in the wastelands of London, he tried to confront him, only to reunite with Wilfred Mott, who had found him with the help of the "Sliver Cloak." They go to a London Cafe, where the Doctor informed Wilf that he is going to die. The Doctor left shortly after seeing Donna, who was engaged to a man named Shaun Temple. At night, the Doctor tracked down the Master once again, who stunned him with lightning from his hands, and forced him to listen to the "Drums" in the Master's head, which the Doctor realised was real, and not just a symptom of the Master's insanity. Soon after, the Master was abducted by Joshua Naismith's private army. The next morning the Doctor contacts Wilf, who informed him of Naismith and goes with him in the TARDIS to the Naismith Estate. In the Manor's basement, the Doctor used the sonic screwdriver to unveil two Vinvocci, called Addams and Rossiter who inform him of the Immortality Gate's true purpose. The Doctor rushed in to stop the Gate's activation, but is unable to stop the Master turning the entire human race in copies of himself - the "Master Race."

Now captured by the Master, along with Wilf, the Doctor attempted to reason with the Master, who realised that with six billion people now hearing the drums, he could trace it to its source. Wilf and the Doctor, were then rescued by the Vinvocci, who took them to their ship, which the Doctor then took offline to stop the Master finding them. Whilst trying to repair the ship (under the pretense of "fixing the heating"), Wilf tried to give him his gun, which the Doctor initially refused to take but relented when an object appears in space lands on Earth which was identified by the Master as a White Point Star- a diamond found only on Gallifrey. Realising the Master has the means to bring back the Time Lords, he pilots the Vinvocci ship back towards the Naismith Manor, dodging missiles, apparently intent on crashing into the Manor. However, he changed his mind, and armed with Wilf's gun, jumps from the ship and crashes through the glass roof. However, he was unable to stop the Master from using the Star and the signal from the drums to create a link to Gallifrey, which allowed Rassilon along with a few other Time Lords to appear in the Immortality Gate.

Rassilon quickly undid the Master's conversion of the Human race and proclaimed him a disease, as Gallifrey appeared next to Earth. The Doctor then revealed exactly why breaking the Time Lock, and allowing the Time Lords to return is wrong. Opening the Time Lock would allow not just the Time Lords to return, but also the Daleks and every other faction in the War, turning the universe into a living hell. As well has this, the Time Lords, in their mindsets warped by the war, had devised a plan to destroy the Time Vortex and ascend to a state of pure consciousness. The Doctor, now recovered from his jump, takes his gun and is torn between shooting the Master- who is part of the link and Rassilon, who created the plan in the first place. Upon seeing a familiar face behind Rassilon, he targets the White Point Star, severing the link, causing Gallifrey and the Time Lords to return to their proper time. Rassilon then tries to kill the Doctor, but is saved by the Master, who uses his powers to fight Rassilon and sacrificed himself as the Time Lords return to the Time War.

The Doctor realised he had survived, but then he heard four knocks -- Wilf, trapped inside the radiation control booth which was about to be flooded with radiation. Despite his own anger and Wilf's pleas to leave him, he released Wilf and took his place, receiving a fatal level of radiation. At first, however, it appeared as if the Doctor had survived this, too, but when a wound on his face suddenly healed itself, the Doctor realized that the regenerative process had started. Unlike previous occasions, however, the actual regeneration did not immediately occur, and the Doctor was able to not only return Wilf to his home, but spend an unknown length of time travelling through time and space revisiting his past companions -- an act he referred to as his "reward":


 * He visited Martha Jones and Mickey Smith (now freelance alien fighters and married) and saved them from a Sontaran.
 * He travelled to 13 Bannerman Road where he prevented Luke Smith from being run over by a car. He departed as Luke and his adopted mother, Sarah Jane Smith, watched.
 * He then travelled to a cantina on the planet Zog (populated, coincidentally, by representatives of many of the alien races the Doctor encountered in his tenth life) where Captain Jack Harkness was drowning his sorrows in a drink. He passed a note to Jack reading, "His name is Alonso." Jack turned to his left to see Midshipman Alonso Frame (DW: Voyage of the Damned), and the Doctor departed as the two began flirting.
 * He travelled to a bookstore where Verity Newman (a descendant of Joan Redfern) was signing copies of her book, A Journal of Impossible Things (the title came from the journal the Doctor wrote in 1913 during his John Smith incarnation (DW: Human Nature), which remained in Redfern's possession). The Doctor had Verity sign his copy, and she realized he was the same Doctor.
 * He then encountered Geoff Noble at some point before the man's death, and borrowed a pound from him. He then travelled a few years into the future and used that pound to purchase a lottery ticket. He arrived at the wedding of Donna Noble and Shaun Temple (some months after he returned Wilf home), and asked Sylvia Noble and Wilf to give Donna the (triple rollover-winning) ticket as a wedding gift.


 * Finally, he travelled to the Powell Estate, on January 1st, 2005, where he observed Rose Tyler and her mother, Jackie Tyler, months before Rose first met him. Although he kept to the shadows, a sudden spasm of pain caught Rose's attention and the two exchanged New Year's greetings, with the Doctor telling Rose that she would have a "really great year."

After Rose departed, the pain of regeneration set in and the Doctor collapsed in the street. Ood Sigma then appeared and told him that while his song was ending, his story never would, and that the universe would sing for him. Reaching the TARDIS, he piloted it into orbit around Earth and he finally regenerated for the tenth time. This time the energy released (probably due to the vast amount of radiation absorbed needed to be purged) during the regeneration was enough to cause massive damage to the TARDIS. (DW: The End of Time). After the End of Time was shown the Series 5 preview was shown.

Undated/unchronicled events

 * Note: The Doctor's discussion with Ood Sigma (DW: The End of Time, Part One) establishes an interval of indeterminate length between the Bowie Base One incident and the events leading to his regeneration, during which many of the events listed below could have occurred.


 * At one point the Doctor travelled with a green-skinned young alien named Majenta Pryce (from DWM: Thinktwice on). Technically, however, the Doctor was considered Pryce's assistant, rather than the other way around. He also briefly reunited with on-again, off-again companion Maxwell Edison who had previously shared adventures with the Doctor's Fifth and Eighth incarnations. (DWM: The Stockbridge Child)
 * The Doctor also shared adventures with Heather McCrimmon and Wolfgang "Wolfie" Ryter. (DWAM)
 * There are several unchronicled periods in the Doctor's history during which his activities are unknown: between Donna Noble's initial invitation to join the TARDIS and his first meeting with Martha (DW: The Runaway Bride, Smith and Jones); and after dropping Bayldon Copper off on Earth and his reunion with Donna (DW: Voyage of the Damned and Partners in Crime). In addition, adventures chronicled following the memory-wipe of Donna do not occur consecutively and thus any length of time may occur between them (from DW: Journey's End onward).
 * During the interval between his first meeting with Donna Noble (DW: The Runaway Bride) and the arrival of Martha Jones, the Doctor briefly travelled with an alien woman named Grayla (IDW: The Whispering Gallery).
 * The Doctor tried to save Elton Pope's mother from a Elemental Shade from the Howling Halls, but is unsuccessful. (DW: Love & Monsters)
 * This occurred some point before the main events of Love & Monsters, as the Doctor recognised Elton as an adult.


 * An unchronicled adventure with Martha Jones involving "four things and a lizard" and requiring the use of bows and arrows occurred in the modern day, during which the Doctor encountered Sally Sparrow and she handed him a package of information relating to events that had yet to occur to him. (DW: Blink)
 * Another adventure involving bows and arrows (possibly the same one?) was recalled by the Doctor during his encounter with Agatha Christie. (DW: The Unicorn and the Wasp)
 * At some point after his encounter with Sally Sparrow, the Doctor and Martha encountered the Weeping Angels and were transported sans TARDIS to 1969, where they spent an unknown length of time following the information provided by Sparrow. Their activities during this period have not been completely detailed. (DW: Blink)
 * At one point, the Doctor and Rose Tyler visited a rocky, barren planet watching giant creatures similar to manta rays in appearance fly past. (DW: Army of Ghosts (flashback))
 * The Doctor marries Queen Elizabeth I, then becomes her enemy. (DW: The Shakespeare Code)
 * This occurs at some point between DW: The Waters of Mars and The End of Time.


 * At some point after leaving Donna, the Doctor causes a change in a planet's timeline that results in a friend named Carla disappearing. Per Carla's request, the Doctor spent "years" searching for what became of Carla in the new timeline, eventually locating her. (DWA: The Haldenmor Fugue)
 * It's unclear whether the Doctor dedicated himself exclusively during his years of searching for Carla.


 * At some point after meeting Lady Christina, and after an adventure involving the Shadow Proclamation and an encounter with Mr. Finch and the Krillitanes, the Doctor rescinds his prohibition on not travelling with companions and invites Matthew Finnegan and Emily Winter, two inhabitants of 1920s Hollywood, to travel with him. (IDW: Fugitive; time placement per IDW: Tesseract) At some point during this period the Doctor was reunited briefly with Martha Jones and UNIT for an adventure (IDW: Don't Step on the Grass).
 * The Doctor may have met River Song and entered into a relationship of some sort with her. (DW: Silence in the Library / Forest of the Dead)
 * It is unclear whether the Doctor's relationship/companionship with River Song occurred during his tenth incarnation. The character is expected to appear in at least two episodes of Series 5.


 * The Doctor saves a 13th century convent from a "demon from the sky" and is named the "saintly physician" by the locals. An image of the TARDIS is later incorporated into a stained glass window commemorating the event. (DW: The End of Time) It is unclear, however, whether this event occurred to the Doctor's tenth incarnation or another.
 * The Doctor once commented that he, Rose Tyler, and an Arcturan once had an interesting experience in a cellar. (BBCR: ''The Day of the Troll)
 * It is not known how long the Doctor spent travelling to visit past companions before succumbing to radiation and regenerating. There may have been encounters other than those recorded. (DW: The End of Time, Part Two)

Companions
As with previous incarnations, the Tenth Doctor has travelled with a number of companions, most notably Rose Tyler, whose loss had a profound impact on him. Others have included (in order) Mickey Smith, Martha Jones (who rejoined the Doctor on at least two occasions after leaving the TARDIS), Jack Harkness (former companion to the Ninth Doctor who rejoined the Tenth on at least two occasions), Donna Noble and Majenta Pryce. He also had opportunity to share at least three adventures with Sarah Jane Smith, companion to his Third and Fourth lives, and he also once briefly took on Rose's mother, Jackie Tyler as an unwilling TARDIS passenger although she later acted as a willing companion during the events of the Medusa Cascade. He was known to have invited at least three individuals, Reinette (Madame de Pompadour), Astrid Peth and Jenny, to be companions, but all died before they could join him (with Jenny undergoing a form of regeneration after the Doctor's departure). Others who had aided him in his adventures (even though they never travelled in the TARDIS) have included Harriet Jones, Jake Simmonds, Mrs. Moore, William Shakespeare, Tish Jones, Sally Sparrow, Agatha Christie, Jackson Lake and Rosita. He also reportedly travelled briefly with a female from the planet Gratt named Grayla, although he chose not to invite her to become a companion, a decision he later regretted.

Following the loss of Donna Noble, the Doctor made a conscious decision to no longer travel with companions. Although this attitude was hinted at in his encounter with Jackson Lake, it was later confirmed when he refuses to take Christina de Souza on as a companion, despite their compatibility, telling her "never again" will he travel with anyone. (DW: Planet of the Dead)

This had not prevented the Doctor from taking on "short-term" companions, usually for the duration of an adventure, as was the case with Lady Christina. Among others: Nikki Jupiter (NSA: Judgement of the Judoon), Jon Bowman (NSA: Prisoner of the Daleks), and even silent film legend Archie Maplin (IDW: Silver Scream). Following an encounter with the Shadow Proclamation at some point after receiving the "He will knock four times" prophecy, and encouraged by the leader of the Shadow Proclamation, the Doctor violated his "no travelling companions" rule and for a time took on two human companions, Matthew Finnegan and Emily Winter (IDW: Fugitive). He also could be seen to have violated this rule in his travels with Majenta Pryce, although possibly not as Majenta - and, to a degree, the Doctor - treated the association more as a business arrangement than an actual companionship (DWM: The Crimson Hand, et al).

During an adventure with former companion Sarah Jane Smith, the Doctor took her own companions, Luke Smith, Clyde Langer and Rani Chandra, under his wing (SJA: The Wedding of Sarah Jane Smith), though they are not considered to have been his companions.

Captain Adelaide Brooke, an Earth space exploration pioneer, briefly served as the Doctor's companion at one point (DW: The Waters of Mars), and he also took Wilfred Mott on as a companion at one point prior to his regeneration after Wilfred sought him out. (DW: The End of Time)

The Doctor shared at least one adventure with Alastair Gordon Lethbridge-Stewart, his old friend and off-and-on companion of most of his previous incarnations. (DWM: The Warkeeper's Crown)

Personality

 * "He's like fire and ice and rage, he's like the night, and the storm in the heart of the sun, he's ancient and forever, he burns at the center of time and can see the turn of the universe, and... he's wonderful." 


 * Timothy Latimer describing Tenth Doctor (DW: The Family of Blood)

Like his predecessor, this Doctor was capable of boundless enthusiasm, though in his case often at inappropriate times, even in the face of danger, something that some (including Queen Victoria, who was so unnerved that she banished the Doctor and Rose from Britain (DW: Tooth and Claw)) found strange or unnerving. While many Doctors have intentionally flouted social conventions, the Tenth seemed to be genuinely surprised when he was 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 or at risk, as when the Wire stole her face. (DW: The Idiot's Lantern) When driven by anger or justice, 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) Son of Mine claimed that by running the Doctor wasn't showing fear, but mercy. While he had resolved much of the survivor's guilt felt previously, he had began to feel his age and, behind the outward playfulness, he felt a deep loneliness. His keen sense of loss led him to empathize 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 and compassion has worn out or diminished. His exuberant demeanour somewhat disappeared after the loss of Rose, and he became angrier and more sober. He was also never as open or caring towards Martha, being less inclined to hug her. However his jovial manner did return marginally towards Donna, but even then his actions still suggest that he never completely overcame his loss of Rose.

The Doctor had 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!" (DW: 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. River Song thought that if he lost this trait the universe would become a darker place. (DW: Forest of the Dead)

He frequently got into trouble because of his vast and loose sense of superiority (DW: 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 Doctor frequently ignored reproach; when companions point out he was committing horrible acts, he ignored them or changed the subject. The Doctor was willing to go to extreme lengths to keep the historic timeline from being disrupted and/or protect innocent civilizations, even to the point of having to cause deaths (DW: The Fires of Pompeii, etc.). However, as time went on, he became more hesitant to kill, choosing often to give his enemies a chance to surrender without suffering any harm. This was a change he attributes to Rose Tyler, telling her she helped him overcome a time in his life that was "full of blood and anger", eventually making him a "better man." (DW: Journey's End). However Donna claims his change is because of Martha. (DW: Partners in Crime)

Upon their first meeting, Donna Noble noted that the reason the Doctor requires so many companions is to keep him from succumbing to his darker urges. (DW: The Runaway Bride) After losing Donna to a meta-crisis, the Doctor chose to no longer work with companions to avoid getting his heart broken again. This time spent alone ultimately resulted in the Doctor succumbing to those darker urges and breaking the laws of time to satisfy his ego. Dismissing his survivor's guilt, the Doctor now claimed to be the winner of his race as though the Last Great Time War was an act of survival of the fittest with the Doctor coming out on top. After saving three members of Bowie Base One, the Doctor stated that the Laws of Time would obey him now, claiming he was the "Time Lord Victorious". Although the suicide committed by Adelaide Brooke after being saved by him forced the Doctor to realize the consequences of his actions, it has yet to be seen if he will continue to ignore the Laws of Time or not. (DW: The Waters of Mars)

Unlike previous incarnations (at least as far as has been chronicled), the Doctor's tenth life saw him engaging in romantic situations far more frequently than his predecessors. Aside from the unique case of Rose Tyler (whose relationship with him began during the Doctor's ninth life), and Jack Harkness, who fell in love with the Doctor in his ninth incarnation (per DW: Utopia, et al), others who have either expressed feelings for the Doctor or attempted to engage him romantically have included Madame de Pompadour (DW: The Girl in the Fireplace), Joan Redfern (albeit the Doctor's John Smith alias) (DW: Human Nature/The Family of Blood), Martha Jones, Astrid Peth (DW: Voyage of the Damned), River Song (although she had a prior relationship with the Doctor) (DW: Silence in the Library/Forest of the Dead), and Christina de Souza (DW: Planet of the Dead). The Doctor reciprocated with all except Jack, Martha, and Christina (his relationship with River being unclear), although in Jack's case it was indicated he was unaware of Jack's attraction to him. Donna Noble never attempted to engage the Doctor romantically, though comments made prior to the erasure of her memory suggested deep feelings for the Doctor (DW: Journey's End).

One thing that this incarnation absolutely refused to do was take up a weapon against an enemy. The Ninth Doctor did at least once when up against the seemingly last Dalek in existence, but the Tenth Doctor wouldn't, repeatedly refusing even when offered one by UNIT while attacking the Sontarans. Even Davros pointed out his refusal to take up a gun, saying that he refuses to take up a weapon, but turns his companions into weapons. In The End of Time, the Doctor once again refuses to take a gun and kill someone from Wilfred despite the sheer necessity of it, but upon learning that the Time Lords were behind everything, he changed his mind and took Wilfred's old service revolver with him to face Rassilon and the Master. Even then he was very reluctant to kill anyone with it and ultimately just used it to sever the link anchoring the Time Lords and Gallifrey, allowing him to defeat them in another way.

Habits and Quirks
The Doctor made frequent reference to twentieth century pop culture, including the Ghostbusters theme (DW: Army of Ghosts), the song "Circle of Life" from The Lion King (DW: The Christmas Invasion), and one of Kylie Minogue's songs, "Never Too Late." (DW: The Idiot's Lantern) He had also read the Harry Potter books, saying that he cried after reading the seventh book (DW: The Shakespeare Code) Even though he knows so much of pop culture he has been shown to not understand certain remarks, such as being called a "science geek." (DW: The Lazarus Experiment) 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 (DW: Blink, et al)

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

The tenth incarnation of The Doctor also has a fondness for bananas like his predecessor. (DW: The Girl in the Fireplace) Here, he remarks to Rose and Mickey (both strapped to operating tables at the time) that they should always take a banana to a party. But the tenth Doctor also has a deep dislike for pears. A deleted scene from (DW: The Family of Blood) shows the whole message of instructions the Doctor leaves for Matha Jones while he masquerades as a human. The message states that he hates pears and Martha shouldn't let John Smith eat a pear.

The Doctor is also fond of the phrase "I'm sorry, I'm so sorry." He has said the phrase a total of 20 times. Another favoured phrase is "Allons-y!". 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", a variation on his previous incarnation's favourite exclamation, "Fantastic!". Soon after his regeneration, the Doctor discovered that his physical changes - specifically the new teeth - made it difficult for him to utter the catchphrase, though he eventually managed to do so. (DW: The Christmas Invasion - deleted scene, although his successful utterance is in the broadcast version)

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 relied heavily upon his sonic screwdriver, pushing it to limits not seen in previous incarnations and even chiding his fifth incarnation for going "hands free". (DW: Time Crash) He also continued to heavily use the psychic paper. (DW The End of the World, The Empty Child, Planet of the Dead; PDA: World Game) Like previous selves, he appeared to have the ability to carry a large and diverse number of objects in his pockets, stating once that they were bigger on the inside. (DW: The Runaway Bride) Tipping his hat at least as far back as his second incarnation, he also revived the occasional use of a stethoscope in mostly non-medical situations, such as the diagnosis of electronic or mechanical fault. (DW: Fury from the Deep, The Horns of Nimon, Rise of the Cybermen, The Stolen Earth)

He had taken to carrying a GSM mobile phone with him; the number can be used to contact him anywhere in space and time. (DW: The Sontaran Stratagem, The Stolen Earth) 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; apparently he can be called using any standard phone. (DW: The Sontaran Stratagem, The Stolen Earth)

He also follows the trend of his immediate predecessors in displaying increasing skill for using the TARDIS, on several occasions even using it in the form of a standard spaceship rather than simply dematerialising it every time. (DW: The Runaway Bride, 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. (DW: Forest of the Dead)

The Doctor also had the small quirk of intending to go to one destination, but walking in the opposite direction, leading to more than a few corrections from others (example: DW: Army of Ghosts). This was similar to his Sixth incarnation's habit of declaring to go one way but then going a different way; this was more of a personal quirk than a bad sense of direction, though.

Body
This incarnation had brown eyes. He had a mole between his shoulder blades that he noticed post-regeneration that he was initially bothered by but quickly warmed to. (DW: Children in Need Special) On several occasions, Donna Noble remarked about his "skinny" build. (DW: Partners in Crime, et al)

Grooming and hair
The Tenth Doctor was happy to have more hair than his previous incarnation (DW: Children in Need Special), whose hair was very close-cut. Though he initially seemed disappointed at not being ginger, he would come to take great pride in his dark brown hair, wearing it in various ways throughout his adventures: unstyled (DW: The Christmas Invasion), in a fifties-style quiff (DW: The Idiot's Lantern), and flattened forwards. (DW: The Runaway Bride)

Clothes
This Doctor had several variations of dress. He had been seen wearing a dark brown (with blue pinstripes) suit (DW: The Christmas Invasion through The End of Time), a blue (with red pinstripes) suit (DW: Smith and Jones through The Waters of Mars) and on rare occasions, a tuxedo. (DW: Rise of the Cybermen, The Age of Steel, The Lazarus Experiment, Voyage of the Damned)

To go with his suits he usually wore a shirt and a tie (otherwise, open-necked/chested with a Henley shirt and T-shirt) (DW: Tooth and Claw, Blink), (DW: Planet of the Ood), a red-hued t-shirt, a brown shirt (DW: The Impossible Planet, 42) or a purple t-shirt. (DW: Midnight) Both brown and blue suits are often accompanied by a light brown overcoat (which he claims was given to him by Janis Joplin). (DW: Gridlock)

The Doctor appears to have more than one suit of each design. The Meta-Crisis Tenth Doctor wore one of the blue suits after his regeneration, and was wearing it when the walls of the universe sealed him in Pete's World. (DW: Journey's End) Nevertheless, the Doctor has subsequently worn the blue suit on several occasions (DW: Music of the Spheres, SJA: The Wedding of Sarah Jane Smith, DW: The Waters of Mars)

His choice of footwear was trainers (more specifically Converse All Stars, or P.F. Flyers Center HI's), in colours ranging from cream (to go with his brown suit), black (for wearing with a tuxedo and on one occasion with his brown suit) or burgundy to go with the blue suit). Another part of the Doctor's attire was a pair of dark tortoise-shell rectangular frame glasses which he called "brainy specs". Although he has been seen to put them on numerous occasions, he once confessed that he didn't need them, they just made him look smarter. (DW: Time Crash)

Lifetime
The Doctor's actual age is a matter of some debate (see The Doctor's age). However, assuming the Doctor's stated age of 900 around the start of his life is correct and/or a starting point, it would appear he lived for approximately six years, given his stated age of 906 just prior to his "death." (DW: The End of Time, Part Two) That said, there are some discrepancies as there are some accounts that suggest his stated tally may not be correct. (DW: The Infinite Quest)

Alternate timeline

 * In the parallel timeline known as Donna's World, this incarnation of the Doctor was the last, as he was killed as a result of his defeating the Empress of the Racnoss without the aid of Donna Noble (who in this timeline never met the Doctor). His former companion, Rose Tyler, along with the alternate timeline version of Donna, eventually restored the original timeline. (DW: Turn Left)

 * Moments after finally being reunited with Rose, is shot by a Dalek and begins a regeneration cycle, but halts it by projecting the energy into his severed hand, which had found and kept in a jar for years by Captain Jack at the Torchwood Hub.

Costuming
David Tennant described his costume "geek chic." 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 of the Doctor.

Regeneration
Russell T Davies has said in an interview that The Tenth Doctor's regeneration has been filmed, was planned out in mind since David Tennant was signed on for the role, Davies also heavily implied had Tennant not played The Tenth Doctor there would have been a different regeneration.
