Tenth Doctor

Unlike his immediate predecessor, who was plagued by melancholy due to his actions during the Last Great Time War, the Tenth Doctor possessed an outgoing, lively and genial demeanour that hid his "survivor's guilt". For most of his incarnation, the Doctor was able to successfully project a convivial and even frivolous front. However, when he had to engage in conflict, the Tenth Doctor's energies would shift toward heroism to reveal a fiercely protective man who resolutely guarded what he held dear, and who could be viciously unforgiving to the forces that dared menace them.

He travelled mainly with three companions: Rose Tyler who had been with him earlier, Martha Jones and Donna Noble. Each relationship was shaped, to one degree or another, by romance; He seemed to genuinely love Rose as the person who helped heal some of the scars of the Time War, he was completely oblivious to Martha's obvious affections toward him, and he insisted upon a platonic relationship with Donna. After he was compelled to wipe Donna's memory completely, he entered a period in which he shunned long-term companions altogether, but made a few exceptions when he felt justified.

When travelling without companions, the weight of being the last Time Lord became much more pronounced. If prodded too much, he would erupt in an almost righteous sense of fury. Indeed, the Tenth Doctor was described by the Moment as "the man who regrets". The fact that he was instantly able to recall the number of Gallifreyan children that he believed had been killed during the war indicated just how keenly he actually felt those horrendous memories.

He met his end after he absorbed a huge quantity of nuclear radiation whilst saving the life of Donna Noble's grandfather, Wilfred Mott.

A day to come
Travelling through the caves of the Death Zone to save Borusa from the Dark Tower, the War Doctor and Cinder found various cave paintings that depicted the Doctor throughout his life; the War Doctor noticed one of "a lanky man in a blue suit", and recognised it as one of his future regenerations. (PROSE: Engines of War)

Post-regeneration
The Ninth Doctor absorbed the Time Vortex from his companion, Rose Tyler, to save her life when she became the Bad Wolf entity and transferred it back into the Heart of the TARDIS. The forces of the time vortex began to destroy every cell in his body, and he had to regenerate to save his life. (TV: The Parting of the Ways) Before regenerating, the Doctor left the immortal Jack Harkness behind on Satellite 5, (TV: The Parting of the Ways) because of his status as a living fixed point in time. (TV: Utopia)

After regenerating the new Doctor noted his new teeth, (TV: The Parting of the Ways) and intended to take Rose to the planet Barcelona. With Rose suffering an emotional crisis over his sudden change, he instead decided to take her home to the Powell Estate in London. En route, he convinced her of his identity by reminding her of the first word his predecessor had said to her, before he began to suffer adverse effects from his regeneration. Experiencing manic hyperactivity, he accelerated the TARDIS' speed. (TV: Children in Need Special)

Crash-landing the TARDIS on the Powell Estate on Christmas Eve 2006, the Doctor fell into a coma after wishing Jackie Tyler and Mickey Smith a Merry Christmas. He snapped out of it briefly to save Mickey and the Tylers from a Roboform Christmas tree, but the stress of waking up too soon made matters worse and he collapsed again.

When the TARDIS was taken aboard a Sycorax spaceship on Christmas morning, he awoke with the help of some tea that seeped into a component of the TARDIS, just in time to stop Fadros Pallujikaa's blood control of humanity. The Doctor challenged the leader to a duel over the fate of Earth. In the ensuing sword fight, the Sycorax leader chopped off the Doctor's hand. However, because he was still within the first fifteen hours of his regeneration cycle, he grew a new hand and went on to win the duel for the Earth. When the Sycorax leader went back on the deal, the Doctor ejected him from the ship, killing him, proclaiming that he was a "no second chances" sort of man.

As the Sycorax fled, Prime Minister Harriet Jones ordered Torchwood to destroy the ship. The angered Doctor spoke some words into her aide's ear, "Don't you think she looks tired", to bring about Jones' premature downfall. After choosing his new outfit, the Doctor had Christmas dinner with Mickey and the Tylers. (TV: The Christmas Invasion)

The Platform One mystery
Resuming his travels with Rose, the Doctor answered a summoning from the Forest of Cheem and discovered the guests of Platform One were disappearing. He stopped a cyborg called Montodon Slemm from harvesting the Forest, but they vanished. Intrigued, he and Rose set off to find out who was responsible. (COMIC: Growing Terror)

Tracking down Cal MacNannovich, the Doctor and Rose travelled to Woldyhool and met film director Zemm Foolini, only to find Cal had also gone missing. Whilst there, he stopped a Bajunx creature from killing the cast and crew. (COMIC: Hyperstar Rising)

Following another trail, the Doctor attended the astro space race. He chased Skip Pyleen across the galaxy in a pod to stop him from stealing and selling the Hyposlip 500 to the Rakkonoids, eventually capturing him and having the corrupt racer arrested. (COMIC: Death Race Five Billion)

The Doctor took Rose to the University of Rago Rago 56 Rago to gather information about Platform One from the Chosen Scholars of Class 55. They found books were being downloaded into students' minds via a mindlink device. However, the software was infected with a Macrobe virus. Fighting off the infection himself, the Doctor stopped the Macrobes from using his Time Lord mind and his TARDIS to spread the infection across time and space. His victory was short-lived when he found the Chosen Scholars had also disappeared. (COMIC: The Macrobe Menace)

Using a book from the Rago university, the Doctor and Rose next ended up on Gameworld Gamma, where they discovered a human colony was being hunted for sport by royalty, headed by Platform guests Mr and Mrs Pakoo. He closed down the games and sent the humans back to Earth. He found the Pakoos had been taken, but he knew that, unlike the others, they had been taken to attract his attention. (COMIC: The Hunt of Doom)

After Rose disappeared, the Doctor finally learned the truth: the vengeful brother of the Moxx of Balhoon, the Elth of Balhoon, had been kidnapping all the guests as he felt they had condemned his brother to his death on Platform One. Recognising his grief with his own, the Doctor released all the kidnapped guests and persuaded them to help Elth through his grief. (COMIC: Reunion of Fear)

New adventures with Rose
The Doctor lost his TARDIS on Serac to a Sontaran squad, led by Snathe. Trying to get his ship back, the Doctor allied with his old enemies on their mission to locate Thanatos the Worldbane, the greatest super-weapon in creation. When they found it, Thanatos killed Snathe and, finding Sontarans to be a stagnant race, plotted to destroy their homeworld, Sontar. Luckily, Lerox, a kind-hearted Sontaran, convinced Thanatos that the Sontarans were worth sparing. The Doctor left Lerox with the idea of founding a new Sontaran rig called "the Hope of Sontar", hopeful that other Sontarans could learn from Lerox's compassion. (COMIC: The Betrothal of Sontar)

When the TARDIS jumped a time track with Rose inside, the Doctor was trapped on the Powell Estate for a week, waiting for its return. After failing to impress Jackie, he moved in with Mickey, disrupting his date with a local girl. Using Mickey's television, the Doctor was able to prevent a Bandrigan from invading Earth. Realising his presence was having a negative effect on Mickey's life, the Doctor left him and Rose to spend a few days alone together when his TARDIS finally returned. (COMIC: The Lodger)

Whilst Rose was at home, the Doctor travelled with a Gråttite called Grayla, (COMIC: The Whispering Gallery) and unsuccessfully tried to save Elton Pope's mother from an Elemental Shade from the Howling Halls. (TV: Love & Monsters)

After collecting Rose from the Powell Estate, the Doctor was summoned to the New New York Hospital on New Earth by the Face of Boe. Inside the hospital, the Doctor discovered the Sisters of Plenitude were creating human clones and infecting them with every disease to develop cures for other patients. Discovering that his old foe, Cassandra O'Brien, had possessed Rose, the Doctor cured all of the clones with the hospital lift's disinfectant, along with the treatments developed by the Sisters, with a reluctant Cassandra's help as she had set them free to rampage. This created a new lifeform in the process, and the sisters were arrested by the NNYPD while the Doctor talked with the Face of Boe.

While the Doctor tried to make Cassandra leave Rose's body and accept death, she found a volunteer in her servant, Chip, for her to enter, but as he only had a "half-life", Chip's body began failing. With Cassandra convinced it was her time, the Doctor took her back in time to die in the arms of her younger self. (TV: New Earth)

After being reduced to the size of flies, (COMIC: Which Switch?) the Doctor and Rose stopped the Mirrorlings from escaping from their dimension, (COMIC: Mirror Image) instigated Krakatoa's eruption to stop the Chalderans from stealing Earth's lava, (COMIC: Under the Volcano) and travelled to a space-station orbiting Jupiter, where they stopped the Disinfectodroids from turning a peaceful planet into the Solar System's planet-sized rubbish dump. (COMIC: The Germ War)

The Doctor and Rose later visited Belgium in 1914 and became caught in a battle between a German platoon, led by the brutal captain Rotmund, and the alien Warfreekz machine. Rose stopped the war by singing Robbie Williams' "Angels", which forced both parties to withdraw as they thought she was the Angel of Death. (COMIC: Warfreekz!)

Taking Rose for a steak meal, the Doctor accidentally transported them to Phijax IV, where they were forced to fight as entertainment for the Glutonoid, who threatened to eat Rose if they didn't. The Doctor injected the Glutonoid with TARDIS pills, which destroyed it. (COMIC: The Glutonoid Menace)

The Doctor and Rose took an accidental trip to 1879 Scotland, where they and Sir Robert MacLeish protected Queen Victoria from an assassination attempt by the Brethren at Torchwood House. As a reward, the Doctor was knighted by the Queen, but he and Rose were also banished from the British Empire because their blasé attitude to danger unnerved the Queen. (TV: Tooth and Claw)

Visiting the British Museum with Mickey and Jackie, the Doctor and Rose discovered a statue of Rose was housed in the museum. Travelling to Rome in 120 to investigate, the Doctor found a sentient machine that could grant the wishes called GENIE and, in a series of paradoxical events, Rose and the Doctor were turned into statues and restored, with the Doctor jumping forward to the Renaissance era and taking sculpting lessons from Michelangelo, sculpting the stone Rose in the museum. With the wishes reversed and the chaos smoothed, the Doctor and Rose wished the GENIE could have its freedom and allowed it to live its life in peace. (PROSE: The Stone Rose) The Doctor then atomised the Waterhive for drowning multiple Navy soldiers to serve as incubators for their larvae. (PROSE: The Feast of the Drowned)

Trying to visit China, the Doctor and Rose became trapped in a virtual reality of London created by a troubled teenager named Craig Phillips, who was trying to recover from his sister's death by creating a fantasy world populated by imaginary people and creatures. Craig expelled Rose into the real world, whilst the Doctor took control of the virtual reality. He rebooted the virtual world with the assistance of Cathryn Lloyd, who was actually a Cyrelleod from Happytimz Universal who accidentally gave Craig the power to create this world. With Craig's imaginary world gone, the Doctor forced him to confront his grief. (COMIC: F.A.Q.)

Separated from Rose after an intended trip to the Moon, the Doctor met archaeologist Frank Openshaw and stopped a lone Dalek's plan to transform every human throughout Earth's history into Dalek form. After this, the Dalek tried to trick the Doctor into finding it a new home so that it could rebuild the Dalek Empire. However, the Doctor gave it a self-destructive Time Ring, which he later used on the Dalek after its true intentions were revealed. (PROSE: I Am a Dalek)

Reunion with Sarah Jane Smith
Following a tip off from Mickey, the Doctor and Rose went undercover at Deffry Vale High School, where the Doctor was reunited with Sarah Jane Smith, who was also investigating the school. After repairing K9 Mark III and making amends with her, he learned that Krillitane oil was being used to boost the children's intelligence and that the Krillitanes were using the children's minds to solve the Skasis Paradigm. After confronting the Krillitanes at the school resulted in him and the others being pursued, K9 sacrificed himself to blow up the Krillitanes with their oil, destroying the empty school in the process.

The Doctor asked Sarah Jane to rejoin him on his travels, but she declined, but suggested that the Doctor allow Mickey to accompany him and Rose on their travels, as he was finally ready to see the universe. Before departed, the Doctor also built a new K9 as parting gift for Sarah Jane, giving it all the memories of the previous model. (TV: School Reunion)

Mickey tags along
With Mickey now aboard, The TARDIS landed on the a spaceship in the 51st century, where the Doctor and his companion found the crewmembers' organs were used as "parts" by the repair droids after the ship had been damaged. The droids created time windows to find the ship's namesake, Reinette, Madame de Pompadour, to complete repairs.

While investigating, the Doctor travelled throughout Reinette's life through use of the time windows, fighting the droids throughout 18th century France and developing a romantic relationship with Reinette. When the droids came to harvest Madame de Pompadour, the Doctor broke through a time window to the court of Versailles in 1758, shattering the connection to the ship and stranding himself and the droids from the ship, causing the droids to deactivate from a lack of purpose.

Initially resigning himself to living with Reinette, the Doctor found a link back to the ship and his TARDIS through her old fireplace. The Doctor tried going back through the fireplace so that he could take Reinette to see the universe, but the loose connection to the time window meant she had already died when he returned. After reading a heartfelt letter she had left him, the Doctor was left devastated. (TV: The Girl in the Fireplace)

After Rose became infected with an Iagnon grub, the Doctor sent Rose into a dream where he was dating her mother and Mickey had an Amazonian girlfriend so her jealously could drive the creature out of her body. (COMIC: The Green-Eyed Monster)

Whilst travelling through time, the Doctor, Rose and Mickey fell through a crack in time, ending up on a parallel Earth more technologically advanced. While the TARDIS had died upon landing in the alternate universe, the Doctor managed to power a surviving piece of the TARDIS, but the piece of the TARDIS required a twenty-four hour recharging cycle before the TARDIS could restore itself.

When Rose found her father, Pete Tyler, was alive in this world, the Doctor cautioned her against making contact, as he wasn't actually her father. While Mickey searched for the parallel version of his grandmother, the Doctor gave in to Rose's request to attend the birthday party of her parallel mother. At the party, the Doctor was horrified to discover a parallel version of the Cybermen had been created, and he could only watch at they crashed the party, and killed the guests inside. (TV: Rise of the Cybermen)

Escaping, the Doctor allied himself with the Preachers, and broke into Cybus Industries to confront the creator of the Cybermen, John Lumic, only to see he had been forcibly converted into the Cyber-Controller. The Doctor bought time by trading philosophical ideas with Lumic while subtly telling Mickey and Jake Simmonds to hack the Lumic family database to find the cancellation code to the Cybermen's emotional inhibitors. Mickey texted Rose the code, and the Doctor connected the phone with the code to deactivate the Cybermen's inhibitors, causing them to explode, along with Cybus Industries.

When it came time to leave, Mickey chose to stay behind to fight Cybermen worldwide, as he didn't fit in with the Doctor and Rose's close relationship. The Doctor and Rose honoured Mickey's wishes and returned to their universe, where they visited Jackie at the Powell Estate. (TV: The Age of Steel)

Further adventures with Rose
After leaving Jackie, the Doctor and Rose were sent into the body of Queen Svelna to destroy an alien infection that was destroying her blood cells, (COMIC: A Delicate Operation) helped to form an alliance between the Dramos and Galathon to save the dying Galathos with the Dramos' healing blood, (COMIC: Blood and Tears) and stopped bad-tempered TV chef Rammzi from taking over Terry's Café.

The Doctor destroyed the ice machine, raising the temperature and releasing humanity. (COMIC: Bizarre Zero) Soon after, the Doctor and Rose rescued human colonists from Wumba's World of Wild, an alien safari park in the 41st century. (COMIC: Save the Humans!)

The Doctor took Rose to Muswell Hill on the eve of Queen Elizabeth II's coronation in 1953, where people had been mysteriously taken from their homes. Taking the "domestic approach", the Doctor found Grandma Connolly's face had been completely removed, and that the same had happened to the others who had been kidnapped.

After Rose also had had her face taken, the enraged Doctor discovered that the Wire was using the coronation to feed on the electrical activity of the brain, "taking people's faces, their essences", using Mr Magpie to do so. After nearly being consumed himself, the Doctor found the Wire and Magpie up Alexandra Palace and climbed after them to prevent the Wire from becoming manifest again by converting the "big transmitter" into a receiver of all of the faces of the people watching the coronation. With Tommy Connolly's help, he turned the receiver back into a transmitter and trapped the Wire's electrical signal onto a video cassette, freeing everyone, including Rose and Grandma Connolly. (TV: The Idiot's Lantern)

In 1974, the Doctor and Rose investigated an alien insect that was kidnapping youths and replacing their blood cells with its own and burnt down the house that the insect was stationed, killing it. (PROSE: CuckooSpit)

The Doctor next took Rose to Phostris to meet the first humans in history who travelled through hyperspace. He found the human pioneers had been reduced to a life of slavery by a super-intelligent cat called Mitzi, who had drifted through hyperspace and gained intelligence and superiority. He stopped her from torturing the population into slavery and foiled her attack on Earth by breaking her connection with hyperspace, which reduced her to a normal cat. After discovering Mitzi was actually Rose's childhood cat Puffin, he left the cat on the Powell Estate in the 1990s to be adopted by a young Rose. (PROSE: The Cat Came Back)

In the city of Vanezia, the Doctor and Rose allied with future musical hit Fredrick Gobbo to investigate an opera house that shouldn't have been located in Vanezia. They found the owner, Magrillo, was draining people's energy to power a machine called the Orchestra, which transmitted mathematic aquations into space. The Doctor overloaded the machine by getting Fredrick to sing a bad song, destroying it and killing Magrillo. After this, he discovered the Orchestra had turned Fredrick into the musical talent he was destined to become. (COMIC: Opera of Doom!)

Facing the Beast
The Doctor and Rose landed inside Sanctuary Base 6 on Krop Tor, a planet that was in perpetual orbit around the black hole K37 Gem 5, and lost the TARDIS following an earthquake. The humans of Sanctuary Base 6, having come to Krop Tor to discover the source of power emanating from the planet's core which allowed the planet to orbit the black hole, refused to divert their drill to collect the TARDIS. In the base, the Beast had been terrorising the explorers and possessing their servants, the Ood. The Doctor and Ida Scott, the science officer of Sanctuary Base 6, descended into the core of the planet and discovered a pit which had started opening. (TV: The Impossible Planet)

With the transport tube back to the surface rendered unusable by the Beast, the Doctor decided to descend into the pit alone. Inside, he came face-to-face with the Beast and tried conversing, though its consciousness had already escaped to Toby Zed, the expedition's archaeologist. Realising the Beast's jailers thought of the Beast's escape, the Doctor shattered the vase keeping the planet orbiting the black hole. At the same time, Toby was ejected from the Sanctuary Base 6 rocket by Rose. Though willing to "go along for the ride", the Doctor discovered his TARDIS by accident; he saved Ida Scott, but didn't have enough time to rescue the Ood. Towing the rocket safely away from the black hole, the Doctor "swapped passengers" and resumed his travels with Rose. (TV: The Satan Pit)

Final adventures with Rose
The Doctor and Rose were in a chase with a Hoix, where the Doctor briefly re-encountered an adult Elton Pope, but Elton ran away as the Doctor and Rose left in the TARDIS.

The Doctor staged a prison break, cured Oscar and destroyed the vampires. (COMIC: Bat Attack!)

Proving to Rose that his adventures were not completely dangerous, the Doctor re-installed a randomiser into the TARDIS, which transported him and Rose to the thirteenth Moon of the thirteenth planet in the thirteenth galaxy, on the thirteenth day of the thirteenth year in the 13th century. There, they met the Triskaidekaphobes, the unluckiest species in creation. The Doctor discovered Bob Kreesus had been kidnapping Triskaidekaphobes and stealing their fortune. After returning the Triskaidekaphobes' luck, the Doctor confronted Bob on a cliff, where Bob accidentally fell to his death. (COMIC: Triskaidekaphobia)

After narrowly escaping the Erewon Armada, the Doctor accidentally landed the TARDIS inside a giant pinball machine, which was used to trap game-addicted people.

Although there was a large bounty on his head, the Doctor stopped the Triggers and their business rival, Don Corpulone, from finding "the Bird", a Glitterbird egg from a rare robot species whose were studded with diamonds. He installed detective robots to arrest the two mob famillies and re-established law and order on the planet. (COMIC: Gangster's Paradise)

The Doctor treated Rose to a visit to Paris. However, they discovered that they had become trapped in the Facade, a computer that enhanced people's perception of "Perfect Paris". Alongside resistance fighters, the Doctor and Rose destroyed the Facade with the use of a computer virus. (COMIC: A Date to Remember)

When Elton Pope used Jackie in his efforts to make contact with him, the Doctor tracked him down on Rose's behalf so Rose could berate him for upsetting her mother. He unwittingly saved Elton from being absorbed by Victor Kennedy after arriving. Kennedy tried threatening Elton's life so he could take over the TARDIS, but the Doctor refused. He told Kennedy that the members of LINDA, who had already been absorbed, would have had something to say about absorbing Elton. They pulled at Kennedy's stomach, causing him to drop his cane. Elton broke the cane's limitation field that was preventing the ground from absorbing him. Though he couldn't save the others' lives, the Doctor brought the consciousness of Ursula Blake back, but stuck as a face on piece of concrete. He then told Elton the truth about his mother's death. (TV: Love & Monsters)

On a Magellan-class star cruiser, the Doctor and Rose met Pakafroon Wabster, "the greatest rock band in history".

(COMIC: Interstellar Overdrive)

The Doctor and Rose went to 2012 to see the Olympics, where they met Chloe Webber, a girl who had been possessed by a lone Isolus, who was trapping other children from her street in drawings to give the Isolus company. Despite attempting to help the Isolus, the Doctor was trapped in a drawing, along with the TARDIS. Inside the drawing, the Doctor was able to draw a depiction of the Olympic torch and pointed at it to aid Rose. Once Rose tossed the Isolus' pod into the Olympic flame to recharge it, the Doctor and the children were freed from the drawing. As the torch bearer had been injured by the pod, the Doctor took his place, lighting the Olympic flame himself. Reuniting with Rose, the Doctor warned her that he felt a "storm" coming when she said that no-one would ever separate them. (TV: Fear Her)

The Doctor and Rose visited a rocky, barren planet and watched giant creatures, similar to manta rays in appearance, fly past, where Rose expressed that she would stay with the Doctor forever. (TV: Army of Ghosts)

The Battle of Canary Wharf
Returning to the Powell Estate, the Doctor and Rose found humanity was being visited by beings believed to be ghosts of loved ones. The Doctor tracked the signal to Torchwood Tower in Canary Wharf and was taken prisoner by Yvonne Hartman, leader of 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 iteration. The original tear was caused by a Void Ship. Two computer technicians, secretly under the control of Cybermen, restarted the ghost shift. The ghosts, who were actually Cybermen, came from the parallel world where the Doctor and Rose had left Mickey. As the Cybermen invaded Earth, the void ship opened, revealing the Cult of Skaro, a group of Daleks (TV: Army of Ghosts) with a Genesis Ark, a Time Lord prison ship containing millions of Daleks.

As Daleks and Cybermen waged war with each other, the Doctor was transported back to the Cybermen's original universe, where he reunited with Pete Tyler at that universe's Torchwood, where the People's Republic took over when the Preachers knew what it was doing. With the Preachers, the Doctor returned to his universe. With the help of a short alliance between the Cybermen and the Preachers, the Doctor rescued Rose and Mickey, who had found his way back to the main universe, from their imprisonment by the Cult of Skaro. In the confusion, Mickey accidentally opened the Genesis Ark and released millions of Daleks. The group then saved Jackie from being upgraded by the Cybermen; Jackie and the parallel Pete had an emotional "reunion" and kissed.

To defeat his warring enemies, the Doctor needed to open the Void; doing so would suck anything covered in "Void stuff" into it and seal off the two universes for good. Realising that Rose was also covered in Void energy, the Doctor sent an unwilling Rose, along with Mickey, Pete, Jackie and the Preachers, back to the parallel Earth, where they would be safe, but Rose refused to leave the Doctor and returned, knowing 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 operation. Rose secured the lever, but couldn't keep her grip. She was saved at the last second by her parallel father and taken back across to the other universe, separating her from the Doctor. (TV: Doomsday)

Grieving for Rose
Journeying on without Rose, the Doctor nearly fell off a cliff on the planet Hondran, but was saved by Kara McGravy. After finding Hondran overrun by the Untra, the Doctor managed to lure them to the edge of a cliff, and allowed carnivorous snake-like plants to eat them. (COMIC: The Hunters)

Following a distress signal, the Doctor began investigating disappearances in a small English village. Aided by Brynn, the last child in the village, he discovered a dying crashed sentient spaceship was abducting children to keep itself entertained with their imaginations. Brynn allowed the ship to feast on his imagination to "finish the story", allowing it to die happily and releasing all the children it had taken. (PROSE: Once Upon a Time)

The Doctor discovered the Floof, a species with the ability to hide in plain sight, had been stalking a man called Tom. Befriending Tom, the Doctor realised the Floof had developed a psychic link with Tom and was unwilling to let him go, killing Tom's wife. Enraged, the Doctor punished the Floof by separating it from Tom, condemning it to eternal loneliness. (PROSE: Corner of the Eye)

Still devastated, the Doctor met Rose one last time on Dårlig Ulv Stranden - also known as "Bad Wolf Bay" - in Norway on the alternate Earth where she now lived. He was able to project a hologram of himself through the last crack in the universe leading to Rose's new home. He had parked the TARDIS in orbit around a supernova for enough power to say goodbye. Rose finally told the Doctor that she loved him, but before he might have confessed an attraction to her, the connection was lost. The Doctor was left alone and teary-eyed, until a woman in a wedding dress suddenly appeared inside the TARDIS. (TV: Doomsday) The woman, Donna Noble, had been at her wedding to Lance Bennett, (TV: The Runaway Bride) unexpectedly finding herself spirited away to the TARDIS without explanation. She loudly protested at where she had ended up, putting the Doctor in a state of bafflement. (TV: Doomsday)

While trying to return Donna to the ceremony on Christmas Eve, 2007, the Doctor chased a taxi across the motorway in the TARDIS as Donna was kidnapped by robot Santas. Successful in saving her, he returned her to her wedding reception, where the robot Santas attacked with bombs disguised as Christmas baubles. The Doctor destroyed the attack force and went with Donna and Lance to H.C. Clements, which had a basement leading to a secret Torchwood base underneath the Thames. There, the Doctor and Donna discovered that Lance wasn't marrying Donna out of love; he was working for the Empress of the Racnoss. They were secretly using Donna as an incubator for Huon particles needed to revive other Racnoss in stasis at the Earth's core; Donna had appeared in the TARDIS because of a magnet-like pull between the Huon particles within her and those within the TARDIS.

Using that magnetic pull to bring the TARDIS to him, the Doctor and Donna travelled back in time to witness Racnoss creating the Earth's creation. Forced back to 2007 by Lance being force-fed Huon particles in Donna's place, which also resulted in him being fed to the Racnoss offspring through a hole dug by Torchwood, waking them. After the Empress failed to take his offer to leave Earth, the Doctor's darker side took him over, and he drowned the Racnoss offspring by flooding the Torchwood base on top of the hole with the River Thames. He ignored the Empress' screams for him to stop, only leaving at Donna's request.

When the Empress tried attacking London with her Webstar, the British military destroyed her along with it. Taking Donna home, the Doctor asked her to join him in the TARDIS, but she declined because his darker side had scared her. After she told him to find someone to help him control his dark side, he proclaimed he didn't need anyone. (TV: The Runaway Bride) After the loss of Rose, the Doctor spent some time sulking in The TARDIS, apparently making so few travels that vast spider-webs began to grow in the ship. He soon began to binge-watch emotional films, such as Love Actually, The Lion King, and Annie Hall, as he ate large quantities of Ice cream. He soon began to collect pets, first another version of K9, and then a Cat, which he decided to name Rose after his lost friend.

Rose-the-Cat would often spend time attempting to convince the Doctor to move on from his loss and to get another companion. The Doctor, meanwhile, found himself totally content accepting his two pets as his new companions, and all that he needed. (COMIC: A Rose by Any Other Name)

Travelling alone, the Doctor visited Croxton Hall and, alongside waitress Daisy White, battled the ghosts of Lord and Lady Tubbs and their houseguests. He used the Ancient Horologe, a timepiece used to measure the passage of time across the dimensions, to transform all the ghosts into humans. After the house was restored to normal, the Doctor attended the Tubbs wedding anniversary. (COMIC: 13 O'Clock)

On his way to Baz's Easy Diner on Agrellian Thaxis, the Doctor instead ended up on a restricted biodome in orbit on the dark side of a planet. When his sonic screwdriver agitated the carnivorous plants housed there, he was saved from an attack by a robot who took him to Professor Brask. Using his psychic paper, the Doctor bluffed his way out of trouble and learnt that the plants had been developed to grow in very weak light to provide crops on the outer worlds, but they had become violently aggressive in bright light as a side-effect. The Doctor mixed a concoction that momentarily pacified the plants, which allowed him to rescue Professor Flynt from Brask's attack and reprogram the station robots to attack the plants. He then tinkered with the station's secondary systems and activated the tractor beam which hauled the Weapontek ship back. The ship eclipsed the sun and, without the light, the plants withered and died. With Brask and his cronies rounded up by robot police, Flynt was left with the prospect of starting their work from scratch with the seed sample Brask stole. (COMIC Green Fingers)

Arriving on the Space Station Alpha in the 36th century, the Doctor met a snag finder called Jimmy and his Welding Bot X-5, who went by the name of "Bert". The Doctor discovered the Klytode had scrambled Bert's circuits and was intending to launch a cobalt bomb on the station, which would cause the station to crash to Earth and destroy it. The Doctor saved Bert, tricked the Klytode into destroying his own planet, and had him arrested. (COMIC: The Snag Finders)

Attempting to see central London's Christmas lights, the Doctor accidentally landed the TARDIS in Daniel Francis Thompson's bedroom. Daniel made his way into the TARDIS and meddled with the controls, transporting the time machine to Belgium in 1914, where they witnessed a German and British football match. After visiting various Christmas periods in Earth's history, the Doctor returned Daniel home. (PROSE: Deep and Dreamless Sleep) Soon after, the Doctor stopped off at a 12th century English village at the time of the Black Death. He discovered the Zeerover virus had turned the villagers into zombies. Making a deal with the Zeerovers, the Doctor cured the villagers. (COMIC: Plague Panic)

Cybermen on Centuria
The Doctor took a break from his travels on the Earth colony world, Centuria. His holiday was cut short when he discovered an army of Cybermen had escaped the Battle of Canary Wharf. Taken prisoner and unable to stop the Cybermen's takeover of Centuria, the Doctor met Jayne Kadett, an investigator. He and Jayne managed to destroy the Cybermen at the heart of the Centuria invasion. They discovered the Cybermen had been rebuilding their army across the universe, so the Doctor took Jayne with him to track them down and destroy them. (COMIC: The Power of the Cybermen)

Following the Cybermen's signal, the Doctor flew an airship across the continent of Azlon, which had now become a gigantic Cyber-conversion factory. The Doctor and Jayne destroyed the factory and found a map that brought them closer to destroying the heart of the new Cybermen empire. (COMIC: Drones of Doom)

Taken prisoner below the arctic lands of Centuria, the Doctor and Jayne met Homaj, a half-cybernised drone. After battling the Ice Snakes and cyber-dogs, the Doctor and Jayne used explosives to destroy the Cybermen's base. Homaj sacrificed himself, and the Doctor and Jayne discovered the key to stopping the Cybermen was by destroying Centuria Central. (COMIC: Enemy Mine)

When Jayne became frozen in time, the Doctor set off to Centuria Central alone, becoming a fugitive. He infiltrated the base and destroyed the stasis machine, which had a mental link to the Cybermen. As a result, Cybermen across the galaxy were destroyed. With the galaxy protected, the Doctor asked Jayne to travel with him, but she declined. (COMIC: Time of the Cybermen) Leaving Centuria, the Doctor took part in a polar expedition on Grothender. (COMIC: Wormhole)

Reunion with the Brigadier
The Doctor visited the Slough of the Disjointed Planets, a 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.

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. He chose the Doctor's old UNIT friend, Brigadier Lethbridge-Stewart, now retired and in his late seventies, who refused to accept the War Keeper's demands. As an alternative, the War Keeper chose Mike Yates, another of the Doctor's UNIT friends, but accidentally summoned another man with the same name.

Rivals of the dying War Keeper infiltrated his helpers before his death and passed onto Yates the Keeper's control device, the Warkeeper's Crown. With the weak-minded Yates under the control of the Crown and the many forces of the Disjointed Planets, the deceased War Keeper's rivals planned to control the conflicts. The controlled Yates transported himself back to 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 Yates from the Crown's control. At this time, the Doctor and the Brigadier were reunite with their Mike Yates. With the danger passed, the Doctor and the Brigadier re-lived their old glories and said their goodbyes, although the Brigadier expected to see his old friend again. (COMIC: The Warkeeper's Crown)

Meeting Martha
While investigating a set of plasma coils, the Doctor checked himself into Royal Hope Hospital in 2008, where he met Martha Jones, a medical student. The hospital was H2O scooped onto the Moon by the Judoon, who were hunting the Plasmavore murderer Florence Finnegan. Pretending to be human, the Doctor tricked Finnegan into drinking some of his blood, which she assimilated into her system, and the Judoon executed her after identifying her as a non-human. Martha revived the blood-starved Doctor, and the hospital was returned to Earth. After leaving the hospital, the Doctor tracked down Martha at a family gathering to offer her one trip in time as a way of expressing gratitude for her assistance. (TV: Smith and Jones)

For her reward, the Doctor took Martha to London in 1599 to meet William Shakespeare, a personal hero of his. Learning the lost play, Love's Labour's Won, was to be performed, the Doctor decided to investigate why it vanished. He discovered the Carrionites had the Globe Theatre constructed to their design in order to use a hidden incantation in the script to free the rest of their kind from the Deep Darkness. Despite succeeding, their incantation was reversed by one improvised by Shakespeare, trapping them and all copies of the play in the Darkness. As it risked freeing them, the Doctor advised William not to rewrite the play. While bidding Shakespeare goodbye, Queen Elizabeth I arrived and ordered her men to kill the Doctor, declaring him her sworn enemy, much to Martha's confusion and the Doctor's amusement. (TV: The Shakespeare Code)

Fleeing the Queen's men, the Doctor decided to stretch the one trip agreement with Martha to a trip to both the past and future. Returning to New Earth in 5,000,000,053, Martha was kidnapped by a couple wishing to use the New New York Motorway's fast lane. Searching for her, the Doctor discovered the city had been plagued and the population had become trapped on the motorway for their own safety. Novice Hame took the Doctor to what was left of the Senate to help the Face of Boe open the Motorway. Martha and the population were freed from being attacked by the Macra, who lived in the filthy air below the cars. After the Face of Boe sacrificed his own life to power the doors keeping the motorway shut, he uttered his secret to the Doctor: "You are not alone". As the city sang in celebration of their freedom, the Doctor told Martha of the Last Great Time War. (TV: Gridlock)

After a bad experience with the dinosaurs, Martha asked to return to the Royal Hope Hospital. While they were there, the Doctor found that the a faction were not sucked into the Void, having been made on Earth during their invasion from the parallel Earth. The Doctor was then arrested by Captain Shelia Shandron, who wanted his help against the Cybermen. The Doctor then phoned Martha and found she had been kidnapped by the Cybermen. Their location found, the Doctor, Burton and Sandron prepared for the Cybermen's attack. After the attack, the Doctor arrived at the Cybermen's base, the Millenium Dome, and pretended to help realease the Cybermen trapped in the void, when in fact he created a time portal to bring a dinosaur to defeat the Cybermen. (PROSE: Made of Steel)

The Doctor took Martha to Harankast, where they stopped Joseph Manver, a ruthless car-dealer, from brainwashing the population into buying cars that polluted the planet, destroying the beautiful countryside. After closing his car business, the Doctor had Manver arrested by the local authorities. (COMIC: Exhausting Evil)

In 1930 New York City, the Doctor and Martha investigated kidnappings from Hooverville, a community of people hit by the Great Depression with nowhere left to go, befriending their leader, Solomon. They also met Tallulah, in search of her boyfriend Laszlo, who had disappeared a few days prior. Investigating the sewers, the Doctor discovered Pig slaves that worked for the Cult of Skaro, who were kidnapping humans with high intelligence for their Final Experiment; the pig slaves were created from those of low intellect. The group ran into Laszlo, and saw how the Daleks had partially transformed him into a pig slave, but he managed to escape with his mind still his own. The Doctor discovered that the Daleks were trying to evolve into new forms in order to survive, and the Cult of Skaro's leader, Dalek Sec, transformed himself into the first human-Dalek hybrid as part of this plan. (TV: Daleks in Manhattan)

To the Doctor's surprise, Sec grew compassionate thanks to his new humanity, wishing to no longer conquer Earth; he wanted the Doctor to take the new human-Dalek race to a new world in his TARDIS. However, the other three members of the Cult betrayed Sec, stripped him of his Dalek superiority, exterminated Solomon and continued with their endless mission to conquer Earth, filling the captive humans with pure Dalek DNA. The Doctor climbed to the top of the Empire State Building and got in the way of the solar flare that powered the experiment; he added Time Lord morality to the hybrids.

After Sec was killed by Dalek Thay in the defense of the Doctor, the Daleks fought the hybrids; Jast and Thay were killed in the battle and Dalek Caan deactivated the hybrids as failures, leaving himself the sole surviving Dalek. Attempting to help Caan, the Doctor was enraged when Caan performed an emergency temporal shift. Laszlo began to die due to the pig slaves' limited lifespan, but the Doctor, using the laboratory built by the Cult, cured his deterioration. However, he couldn't fix Laszlo's disfigurement, so he left him and Tallulah to live their lives in peace as new residents of Hooverville, where no one would judge Laszlo's appearance. (TV: Evolution of the Daleks)

The Doctor brought Martha back home, exactly twelve hours after they left, planning to leave and continue his travels alone. However, he decided to stay to discover what Professor Richard Lazarus was up to after hearing that he was going to "change what it meant to be human". Attending Lazarus' demonstration, the Doctor met Martha's family, with her mother, Francine Jones, taking an immediate dislike to him. The Doctor discovered Lazarus had created a machine to restore youth. However, the machine backfired, mutating Lazarus into a monster that fed off the life force of others. Following Lazarus into Southwark Cathedral, the Doctor saved Martha and her sister, Tish, from being drained by Lazarus by using his sonic screwdriver to enhance a pipe-organ to reverse the machine's effect and revert Lazarus to his original self, but not before Lazarus had fallen to his death. Per Martha's request, the Doctor took her on as his official travelling companion. (TV: The Lazarus Experiment)

The new companion
Travelling with Martha, the Doctor met a younger version of the Moxx of Balhoon, who was a solicitor for the Slitheen, who wanted to sue the Doctor for abducting their offspring. However, the Doctor proved that the Slitheen children had stowed away aboard the TARDIS of their own free will. (COMIC: Who Ate All the Biscuits?)

The Doctor and Martha searched for the Infinite, a spaceship also sought by Baltazar. (TV: The Infinite Quest)

After upgrading Martha's phone in mid-travel, the Doctor locked onto the distress call sent out by the SS Pentallian, that was plummeting into the Torajii sun. The Doctor offered to help evacuate the ship, but was unable to when the TARDIS was trapped in the ship's boiler room. A malevolent force that has possessed Hal Korwin, the husband of the ship's captain Kathryn McDonnell, began reducing the rest of the crew to cinders. Eventually, the Doctor discovered that Torajii was sentient and seeking revenge on McDonnell for scooping out some of it to use as fuel, and possessed him after Korwin was sedated. Holding off possession long enough, the Doctor told Martha how to get rid of the fuel to appease Torajii. She did so with the last surviving crewmembers and the Doctor was released from its possession. After this, he gave Martha a TARDIS key. (TV: 42)

The Doctor was incapacitated by the green mists of Orion's Belt, (COMIC: Ground Control) encountered the Zygons in 1909, (PROSE: Sting of the Zygons) and was nearly forced to be a living exhibit in the Gallifreyian section in the Museum of the Last Ones. (PROSE: The Last Dodo)

After losing the TARDIS in the time winds, the Doctor and Martha took up residency on a luxury astroliner called Tritanic. However, the ship was attacked by the Skrawn, whose homeworld had been destroyed in the Last Great Time War. The Skrawn stole the astroliner's experimental time-nav system to overpower the Kolox nebula. In pursuit, the Doctor found his TARDIS aboard the Skrawn's ship, and stole the time-nav, leaving the Skrawn lost in the Kolox nebula. (COMIC: The Skrawn Inheritance)

The Doctor next took Martha to Maught, a planet resembling the American Wild West, where he stopped three criminals, Tu, Blontt and Angelo, from stealing water of gold. (COMIC: The Green, the Bad and the Ugly)

On a trip to Egypt in 2375, the Doctor and Martha watched the Great Pyramid of Cheops vanish. Intrigued, the Doctor tried to track it down and materialised the TARDIS by the Temple of Diana at Ephesus, just as it disappeared. Travelling to Greece, 280 BC, he and Martha saw the Colossus of Rhodes vanish. The Doctor also discovered that the statue of Zeus at Olympia and the Pharos lightho at Alexandria had also vanished, which left only one of the Seven Wonders of the Ancient World - the Hanging Hardens of Babylon. Having anticipated its disappearance, they were approached by a Talithan swindler called Pholonius Ginn, who planned to sell the wonders on g-Bay. All three were teleported to the deep space station headquarters of the FatKat Corporation, an auction for planet Earth and all inhabitants born in the Humanian period. Ginn bought Earth, but the Doctor distrupted the deal as Ginn had bought control of every inhabitant of Earth - except Martha, which subsequently ruined his business deal. Afterwards, the Doctor returned the Seven Wonders to their original positions. (COMIC: Minus Seven Wonders)

The Doctor and Martha next became caught up in a decade-long alien war and discovered the guns used in the war placed the target in suspended animation rather than killed them. The Doctor stopped one of the last survivors, Elphon, from slaughtering everyone involved in the war in a desperate act to end the raging conflict. He brought the two warring species together and freed the hundreds of warriors that had been suspended. (COMIC: The Last Soldier)

After watching the Beatles in 1960s Liverpool, Martha was kidnapped. Intrigued, the Doctor traced her to Gelezen, a planet that was isolated from the rest of the universe thousands of years ago. Breaking the time field around Gelezen, the Doctor stopped the Gelezens from taking Martha's human DNA to survive, instead giving them his own genes to ensure they had a long future. (COMIC: Signs of Life)

After leaving Gelezen, the Doctor and Martha visited Fraxinos, where they met Natalie Sharrocks, who was on the run from the Chelonian. Investigating, the Doctor was led to a company called the Body Bank, which allowed the aged to regain youth via mind transference. Undercover as a health inspector, he learnt an entity had taken Natalie's body whilst she was at the clinic to destroy a Chelonian breeding planet. The entity took control of another patient, who later died of a heart attack, killing the entity and saving Natalie from Chelonian retribution. (COMIC: The Body Bank)

The Doctor and Martha next visited the Great Solar Shields, which was used to take the heat off 21st century Earth to ease the effect of global warming. Aboard, the Doctor encountered the Silhouettes, mythical creatures, when they began murdering the crew. He stopped them from unleashing a swarm onto Earth, which caused the Shield to break up. (COMIC: Sunscreen)

While in Blackwood Falls, the Doctor encountered the Hervoken, old enemies of the Carrionites, and prevented them from using the energy of the townspeople to launch their ship. (PROSE: Forever Autumn) The Doctor next found a Voracious Craw heading towards Tiermann's World in the 35th century. They arrived there to save the Tiermann family, but due to the intelligence at the heart of the Dreamhome, the Domini, being possessive of the family, they could only save Solin. They then chased the Voracious Craw off Tiermann's World by using a copy of the alien's species to scare it off the planet before it could finish consuming it. (PROSE: Sick Building)

Battles in time
During a trip to a supermarket, the Doctor and Martha encountered a rampaging warrior called Thaur, one of three warrior kings separated, banished and exiled from Norsum by a goddess called Angboda. During a scuffle, Martha caught Thaur's necklace, a crystal and his only link with his homeworld. Looking into the crystal, the Doctor saw a fleet of war-craft under construction, commanded by Angboda in order to attack civilisations across the galaxy. Instead of handing him over to the authorities, the Doctor took Thaur aboard the TARDIS to stop the attack on the galaxy. (COMIC: Wrath of the Warrior)

The Doctor and Martha located Vulsturg the Vast, Thaur's fellow warrior king, imprisoned on a planetoid. When they tried to free him, slimy green flying creatures emitted a deafening scream. Reversing the sonic field of three hearing aids, the Doctor blocked the sound and rescued Vulsturg. When a large beast tried to stop their escape, the Doctor attached the three hearing aids to each of its three ears then soniced them back to a normal setting. The beast was overcome by the amplified screaming and fell unconscious. The Doctor, Martha, Thaur and Vulsturg then left in the TARDIS to find the third warrior king. (COMIC: The Screaming Prison)

They travelled to a prison on Haklok, only to find the place littered with bodies, including those of robo-sassins, which had been sent to stop the group from finding the warrior kings. Looking into Thour's crystal, the Doctor realised that Angboda's fleet were in fact hospital ships travelling to help the worlds that Thour and his two fellow warriors had attacked. Having been tricked by Thour, the Doctor and Martha were left behind as the three warriors stole the battle cruiser and set off to avenge themselves against Angboda. (COMIC: Force and Fury) Angry and guilty for being tricked into freeing Thaur and his two accomplices, the Doctor travelled to Queen Angboda's hospital ship to defend it against Thour's imminent attack. With no weapons to use, the Doctor, Martha and Angboda instead jettisoned everything in the ship's cargo bay, creating a reflective barrier with Thour's laser that heavily damaged his ship and caused it to crash onto a barren asteroid, leaving the three warrior kings stranded and powerless. (COMIC: Warriors' Revenge)

Responding to a distress call from Professor Dinsdale of the Interplanetary Archaeological Institute on Brendock Seven, the Doctor discovered Dinsdale's team had been killed trying to open an ancient burial mound. The Doctor managed to bypass the door's sonic disruptor, and found the Vortex Cannon, a weapon capable of universal catastrophe, created by an ancient and long-dead civilisation. To his horror, the Doctor unmasked Dinsdale as a shape-changing Zaan Warrior, and the Zaan escaped with the Cannon, only to be destroyed by the guardians of the burial mound. The Zaan commander survived and escaped in an escape pod. Knowing that Treed Crystals that powered the Cannons were found only on the planet Garvrath, the Doctor and Martha set off in pursuit of the Zaan commander. (COMIC: Head Start) After spending a while tracking the Zaan, the Doctor and Martha attended a film premiere, knowing that the leading star, Honey Vox, wore one of the best examples of a Treed Crystal, and would be a likely target of the Zaan. They contacted her and discovered the Treed Crystal locked in her safe, but stolen by Jebelex the Pulthasian using a matter transmuter. As the Zaan arrived, Jebelex tricked them into thinking he had chucked the crystal to Martha and escaped in his ship. Using the matter transmuter, the Doctor and Martha went off in pursuit of the crystal, following a trail of Jebelex' DNA. (COMIC: Jewel of the Vile)

Tracking Jebelex, the Doctor and Martha arrived on Karaten, where the Doctor was thrown into a living water entity by the hostile villagers, where the Doctor found the skeleton of Jebelex, and the Treed Crystal. On the Doctor's instructions, Martha used Jebelex's matter transmuter to turn liquid into a solid, freeing the Doctor and allowing him to destroy the entity. With the crystal in his possessions, the Zaan arrived and kidnapped Martha, threatening to kill her unless the Doctor delivered the crystal to their homeworld. (COMIC: Lock, Stocks and Barrel)

After chasing the Zaan across space, the Doctor discovered the crystal was actually a trap. He freed Martha and tricked the Zaan into using the crystal, trapping the Zaan and their homeworld in a time-loop for eternity, although he did feel a sense of guilt for what he had done. (COMIC: End Game)

Being human
The Doctor and Martha found themselves being pursued Family of Blood, who wanted his Time Lord body to achieve a form of immortality. (TV: Human Nature) Rather than confront them directly, the Doctor, out of mercy, chose to hide from the them instead, to save them from his fury. (TV: The Family of Blood)

He used a Chameleon Arch to transform himself into a human school teacher named John Smith in 1913 England, completely repressing his Time Lord self, and sending Martha undercover as his maid to protect the Arch, as his alter ego would have no recollection of the Doctor, only dreams of his adventures.

However, John Smith fell in love with the matron of the school, Joan Redfern, (TV: Human Nature) and initially refused to change back as he had adapted a normal life and had forseen a bright future with Joan, but decided to allow the Doctor to retake his Time Lord body so he could save the Earth from being attacked by the Family.

Haunted by all the death and destruction his act of mercy had caused, the Doctor gave the Family their immortality, with ironic punishments: he trapped Father of Mine in chains forged in a dwarf star, Mother of Mine in the event horizon of a collapsing galaxy, suspended Son of Mine in time as a scarecrow and trapped Daughter of Mine in every mirror in existence. He also offered Joan a chance to come with him, telling her that he was capable of all the things John Smith had been, but she declined, knowing that John and the Doctor were no longer the same person. (TV: The Family of Blood)

Further travels with Martha
Intending to take Martha to the Medusa Cascade, the Doctor found himself trapped in an abandoned mansion, where he faced illusions of his past. However, he managed to overcome his worst fears and saved Martha from hers. (COMIC: Mind Shadows)

Before they could leave, they and the crew were transported to the oceanworld of Surobos, where they were sentenced to death by the Suroban. Making a deal with a friendly Suroban, the Doctor ventured into the ocean to retrieve his TARDIS and returned the Seamancer crew to Earth. (COMIC: Shipwreck!)

Seeking peace and respite, the Doctor took Martha to an icy alien city called Isqaron, where they discovered the city was melting and that the population believed it was the work of a god called Asharoth. Empress Tamil believed the Doctor to be an escaped slave of Asharoth and had him thrown through a dimension gateway. The Doctor found himself deposited on Earth, where he learnt a group of scientists, led by Professor Milligan were using Isqaron as air conditioning for Earth, pumping hot polluted air to Isqar and sucking cold pure air back. The Doctor convinced scientist Kate Curran of the dangers they were doing and destroyed Malligan's work with her help. He and Kate then flew through the gateway in a helicopter and saved Martha and the city. (COMIC: Cold War)

On Lumana, the Doctor and Martha were enlisted into protecting the Loomish from the reptilian Slaken. However, he soon discovered the Loomish were con artists and had led him off to find the Slaken so that they could take up residency in the TARDIS. Martha tricked the Loomish into thinking one of their family members were in dangers, and she and the Doctor quickly escaped in the TARDIS when the Loomish briefly left the ship. (COMIC: House Pests)

After detecting an inexplicable power source, the Doctor and Martha travelled to Zetheda, only to discover the whole planet to be overflow with un-recycled waste. They were attacked by the Worgoth, but were saved by the Ratlings, who sent the distress signal leading the TARDIS to Zethenda in the first place. The distress beacon also attracted the attention of the Optimi's, a race of evolving humans who wanted to colonise the "paradise" world of Zethenda and destroy the Ratlings. Escaping, the Doctor, Martha and the Ratlings activated a terraforming device hidden underground that created a paradise landscape. In the end, the Ratlings and Optimi came to a compromise: the Ratlings would inhabit the wastelands, whilst the Optimi would live in the paradise they had been searching for. (COMIC: Waste Not)

The Doctor discovered a Vurosis in Creighton Mere and, to prevent it from harming the populace, killed the alien by forcing its mutategenic powers back on it, (PROSE: Wishing Well) encountered space pirates in the 40th century, (PROSE: The Pirate Loop) and found living weapons known as the Clade causing trouble in 1880. (PROSE: Peacemaker)

The Doctor and Martha were transported back in time to 1969 by the Weeping Angels while investigating strange disappearances at Wester Drumlins in 2007.

At Christmas, the Doctor took Martha shopping in Oxford Street in the 38th century, where he re-encountered Jimmy and "Bert". Spending Christmas with them, the Doctor learnt Jimmy had fallen under the control of another Klytode, who wanted to use Jimmy's new ecopower station to unleash the Prime Klytode onto Earth. He succeeded and Klytode's began invading London. Refusing to allow Bert to sacrifice himself, the Doctor reversed the hyperspatial link that brought the Klytode to Earth, sending the Prime Klytode and his army back to were they originated. (COMIC: A Klytode Christmas) After spending Christmas with Bert and Jimmy, the Doctor landed aboard a research base in deep space, which was populated with dead alien beings. (COMIC: Death to the Doctor!)

Another trip brought the Doctor to Snowglobe 7 in 2099. There, he was forced to commit genocide by destroying the Gappa race to keep humanity safe from them. (PROSE: Snowglobe 7)

The return of the Master
On another refuelling trip to Cardiff, the Doctor caught a glimpse of his immortal former companion, Jack Harkness. Fearing Jack's "impossible existence", the Doctor set off immediately after the TARDIS was refueled, but Jack managed to jump onto to the exterior of the TARDIS. The TARDIS reacted badly, flying all the way to the end of the universe, with Jack clinging on to it.

On Malcassairo, which populated the last of humanity, the Doctor had a tense reunion with Jack. Whilst investigating the planet, they saved a human from being hunted by cannibalistic humanoids called the Futurekind. Fleeing the Futurekind, the trio entered the Silo, the asylum of the last survivors of the universe and the launching point for the most ambitious trip in history: Utopia, supposedly a haven beyond the collapse of reality. The Doctor, Jack and Martha assisted Professor Yana in powering up the rocket. However, the Doctor learnt Yana was actually, having made himself human to escape the Last Great Time War using a Chameleon Arch. Restoring his Time Lord consciousness out of curiosity from Martha's questions about his watch, Yana became the Master again, and killed Yana's assistant, Chantho, but not before she was able to shoot him. Facing imminent regeneration, the Master locked himself inside the Doctor's TARDIS and, once he regenerated into, hijacked the ship and escaped, leaving the Doctor, Jack and Martha to be killed by the Futurekind at the end of the universe. (TV: Utopia)

Before the Futurekind to kill them, however, the Doctor was able to fix Jack's vortex manipulator, and used it to bring them back to 2008. Once there, they discovered the Master, using the alias "Harold Saxon", had been elected Great Britain's Prime Minister, forcing the Doctor, Martha and Jack to go on the run after the Master framed them as terrorists. He had also sent Torchwood Three to the Himalayas and captured Martha's family, after he has tricked Martha's mother into helping him entrap the Doctor.

On board the Master's airship, the Valiant, the Doctor discovered his TARDIS had been turned into a paradox machine. After failing to use a Perception filter to foil the Master's plot, the Master summoned theToclafane, whom he ordered to assassinate US President Arthur Coleman Winters, attack the Earth, and decimate the population, while killing Jack and aging the Doctor into an old man with his laser screwdriver. (TV: The Sound of Drums) As the Toclafane began slaughtering the population, the Doctor sent Martha away with Jack's vortex manipulator after whispering his plan to thwart the Master into her ear. (TV: The Sound of Drums, Last of the Time Lords)

Being kept prisoner aboard the Valiant for a year, the Doctor, Jack and the Jones family witnessed the Master and the Toclafane devastate Earth's civilisations, such as Japan, and reduce the human race to camps of survivors, while the Doctor finally realised that the Toclafane were the humans he had encountered at the end of the universe, and began to telepathically hack into the Archangel Network.

After Martha return to the United Kingsom, the Doctor was further aged into a diminutive body by the Master to spite Martha. When Martha allowed herself to be taken to the Master for execution, she and the Doctor revealed their plan; using the Archangel Network, the Doctor harnessed the psychic energy of humanity's hope, as Martha had spent a year travelling the world telling humanity about his importance to them, regaining his youthful appearance in the process. He then forgave the Master for everything he did, inflicted a blow to the Master's ego. On the Doctor's orders, Jack destroyed the paradox machine keeping the Toclafane in the present, undoing the entire year; time resumed for everyone else right after the president was killed, but those on the Valiant retained their memories due to being at the "eye of the storm".

However, while the Doctor planned to keep the Master his prisoner, Lucy Saxon, the Master's human wife, shot him, and the Master refused to regenerate to spite him, and died in the Doctor's arms, devastating him. After burning his old friend's body, the Doctor offered Jack the chance to rejoin him on the TARDIS, but Jack declined, saying that his Torchwood team needed him. (TV: Last of the Time Lords)

Repairing the TARDIS, but forgetting to put his shield's back up, (TV: Time Crash) the Doctor prepared to depart with Martha, but found she also wished to leave him to help her family recover from the year-long ordeal they had suffered, and also told him she was in love with him, but knew he'd never return her feelings. However, she gave him her upgraded mobile phone so that she could call him if trouble arose. (TV: Last of the Time Lords)

Shields down
Immediately after Martha left, the Doctor crashed his TARDIS into that of his fifth incarnation's, which put the universe in danger of being sucked into a Belgium-sized black hole. However, the Doctor used his memory of the event from his fifth incarnation's viewpoint to create a supernova at the exact same moment the black hole appeared. After giving a heart-felt speech of appreciation to his past self, the Doctors' TARDISes separated and the two parted ways. (TV: Time Crash) Before he could turn the TARDIS' shields back on, the spaceship Titanic crashed through the walls. (TV: Last of the Time Lords, Time Crash)

After fixing the damage to his TARDIS, the Doctor attended a party on the Titanic on Christmas Eve, 2008, where he befriended Morvin and Foon Van Hoff and a waitress named Astrid Peth. During a brief trip to Earth with Astrid, the Van Hoffs, Mr. Copper, and a Zocci named Bannakaffalatta, the Doctor also met Wilfred Mott.

When the ship's owner, Max Capricorn, had a meteor shower purposely crash into the Titanic so that it would crash on Earth and wipe out six billion humans, the Doctor took command of his surviving friends, and an arrogant businessman named Rickston Slade, and tried to lead to safety. However, Morvin died, and Foon and Bannakaffalatta gave their lives to save the others. Whilst his party of three survivors reached the flight deck, the Doctor was taken prisoner by Max and was nearly killed by the Heavenly Host on Max's orders. He was saved by Astrid, who lifted Max, with a forklift, taking him with her into the Titanic's nuclear storm drive. With Max dead, the Hosts recognised the Doctor has the new authority and took him to the steering wheel, where he, alongside Midshipman Alonso Frame, stopped the Titanic from crashing into Buckingham Palace.

Using Astrid's teleport bracelet, the Doctor managed to bring Astrid back, but only as a partially cohensive form. Devastated, he kissed her goodbye and allowed her atoms to scatter into space to see the universe. The Doctor then went to Earth with Mr. Copper to find his TARDIS. The Doctor rejected Copper's request to travel with him, though Copper had accidentally brought more than enough credits to get on Earth. After Copper left to start a new life on Earth, the Doctor set out on his own. (TV: Voyage of the Damned)

Travelling alone
Travelling on his own again, the Doctor recommended Martha Jones for a job at UNIT, as a way of thanking her for everything she had done for him. (TV: Reset, The Sontaran Stratagem)

Visiting a house on Christmas Eve 1920, the Doctor met a boy named Tom Wake. He discovered a sonic screwdriver hanging from the tree and a note for him with the screwdriver, which thanked him for saving the family's life on Christmases in the next nine decades. With this, he travelled to every Christmas between 1920 and 2007, protecting the Wake family. As time passed, the Doctor grew closer to Tom, his wife Alice and their children and grandchildren. Eventually, the Doctor and Tom reached Christmas 2007 and discovered it was Tom who left the note for the Doctor, instructing him to protect his descendants. (PROSE: The Hopes and Fears of All the Years)

Whilst travelling, the Doctor was contacted by Martha Jones via the TARDIS telepathic circuits. After reuniting with her, they were chased into the TARDIS by the Cybermen, where the Doctor uncovered the truth: the Cybermen were actually psychic projections and Martha was actually being impersonated by the Beast. As the Beast took control of the TARDIS, the Doctor tricked the Beast into turning into Martha again and ejected him into the time vortex, defeating him once again. (COMIC: The Beast Is Back In Town)

The Doctor went on the trail of the Extron, a galactic criminal, after the alien parasite kidnapped Violet Hopley, a nine-year-old girl.

Intending to brush up on his language skills, the Doctor's lesson was cut short when he became trapped in the News Factory, a virtual world of crystalline matrix populated by journalists, including married couple Ray and Boudica Royce, whom the Doctor allied with to destroy the aggressive SubEds and the News Factory itself by distrupting the crystalline matrix. (COMIC: Hot Metal)

Landing in a cavern next to a pool of superheated water, the Doctor came under attack from flying aliens called Shrikes. He was rescued by a youngster called Kaze, who led him to a village and the villager's leader, Genji, who invited him to the Ceremony of Choosing, when warriors to defend the village against the Shrike were selected. After the ceremony, the Doctor and the rejected group were thrown from a cliff and came across a crashed spaceship which had used up all its energy shielding itself from the Shrikes. The Doctor landed his TARDIS on the ship, connected his engines with the ship and gave it enough power to launch. (COMIC: The Halls of Sacrifice)

After burning toast in the TARDIS, the Doctor was forced to land in a purple alien jungle, where he met Mason Burns, an archaeologist searching for the final resting place of the Old Kings of Skarab.

Finding and sealing the kings tomb, the Doctor left Mason to lead a revolution on Skarab. (COMIC: The Old Kings of Skarab)

The Doctor was summoned to 19th century China by an old acquaintance, Chan Chiu, and learnt that immortal spirits were operating at the temple of Qingyange. Taking Li, Chan's nephew, to investigate, the Doctor found the spirits under the command of a stone monkey and his governor. Taken prisoner, he challenged the stone monkey for the future of Earth: they both had to defeat a dragon to seal their power over Earth. The Doctor won the challenge, defeated the dragon and drove the stone monkey and his spirits away from Earth. Leaving, the Doctor travelled to the future and visited Li in his eighties, as he was telling his grandchildren about their adventure. (COMIC: Reign of the Stone Monkey)

The Doctor began tracing one half of a silicoid space-folder from Omikros, a device capable of folding space to allow instantaneous travel. He found it in the possessions of a boy called Tom Blakeney. However, Tom's dog Sammy found the other half of the device, opening a portal for a being called Ramadra of the Omikron invasion force to take over and transform him into a tall wolf-like alien. Ramadra connected the two halves, allowing the Omikron invasion force to flood through to Earth. The Doctor used his sonic screwdriver to temporarily reverse the fold between Omikron and Earth, closing the rift before all of the invasion force could pass through. Pursued by the force already on Earth, the Doctor and Tom seized the recovering space-folder from Ramadra. Ramadra overpowered the Doctor, Tom appealed to his little dog Sammy, lost in Ramadra. The Doctor distracted him by throwing a stick that Ramadra chased after, allowing the Doctor time to separate the two halves of the space-folder, sending the force back to Omikron and reverting Sammy back to the form of a dog. (COMIC: Every Dog Has His Day)

On Earth, the Doctor discovered Max Capricorn's henchmen had kidnapped Jack Harkness, mistaking him for Max. With Martha, the Doctor travelled to Penhaxico Two and rescued Jack. (COMIC: Escape to Penhaxico)

The Doctor stumbled onto Majenta Pryce's operation in the Hotel Historia, a chain of time-travelling hotels that had been destroyed in the Last Great Time War, while confronting the Graxnix in 41st century London and used the faulty tech to travel back to the hotel. The Graxnix followed the Doctor and started to kill people at the hotel. Majenta quickly decided to leave with her bills unpaid, but the Doctor prevented her escape. He used her time travel tech to imprison the Graxnix outside time, then ensured she was taken to debtors' jail. (COMIC: Hotel Historia)

After finding the corpse of Dr. Kaleb Loss on the posionous planetoid Death's Door, the Doctor returned Loss to the Institute of Exo-Contamination Treatment base on Mustron V, only to be attacked by the base's protector, a Vox. He was saved by Rachel Barlow and allied with her to unmask a sabotuer who was distrupting the team's work. After an attempt was made on their lives, the Doctor and Rachel discovered Jennifer Arden, a medical officer, was responsible due to her disagreement with the methods of the team's leader, Mick Hogan. When Jennifer infected herself whilst fighting with Hogan, the Doctor used samples collected by Kaleb Loss to cure her. (COMIC: The Poison Planet)

Reunited with Donna
While investigating Adipose Industries, the Doctor was reunited with Donna Noble, who had spent months searching for him as she had come to regret rejecting his offer to travel with him. With Donna's help, he used two Adipose Industries pendants to prevent a million Londoners from being killed and their organs and skeletons converted into Adipose babies. The Doctor tried to save the life of Matron Cofelia, the foster mother to the few thousand Adipose that made it through before the birthing stopped, but the Adiposian First Family's ship dropped her as it took aboard the incomplete harvest of Adipose, killing her.

Deciding to take Donna on as a companion, the Doctor and Donna were both quick to rule out the possibility of a romantic involvement, making their companionship dynamically different from those of Rose and Martha. He flew the TARDIS to where her grandfather, Wilfred Mott, was looking at the stars through his telescope, waving to him along with Donna before heading off into the stars. (TV: Partners in Crime)

Early exploits with Donna
For her first trip in time, the Doctor accidentally took Donna to 79 Pompeii, where they discovered Mount Vesuvius was on the verge of eruption. Initially determined to escape to avoid tampering with the fixed point in time, the TARDIS was sold to the marble merchant Lobus Caecilius before the Doctor could return to it. Despite trying to leave when he reunited with it, the Doctor took an interest in the stone circuits the augur Lucius Petrus Dextrus had designed for Caecilius to make. The Doctor discovered Pyroviles were attempting to take over the Earth after losing their own world by converting humans into their own kind by using the circuits as an energy converter. Having the choice between the death of the entire world or of the thousands in Pompeii, the Doctor made Vesuvius erupt, with Donna's help and support. Per Donna's request, the Doctor saved Caecilius and his family, becoming their household gods. (TV: The Fires of Pompeii)

Setting the TARDIS controls on random, the Doctor ended up taking Donna to 4126, the Ood Sphere. Upon finding a dying Ood, the Doctor was shocked to see it display red eyes; worried that he may run into an old foe, he decided to investigate. They sneaked into Ood Operations, where they discovered the Ood of the Second Great and Bountiful Human Empire were slaves.

They soon discovered that Oods were born with secondary brains, which gave them individuality; however, they were lobotomised and had the translator put in its place. Allied with Ood Sigma, they turned off the force field preventing the Ood from connecting to the Ood Brain, while the CEO of the Ood Operations was turned into Ood as punishment. (TV: Planet of the Ood)

After he rescued Charlemagne from an insane computer, (PROSE: The Lonely Computer) the TARDIS became damaged, and the Doctor and Donna were taken prisoner by a space-junk dealer called Silas Wrench, who wanted to sell the TARDIS as scrap and sell the Doctor and Donna to slave masters. Alongside a Horobot, the Doctor used the TARDIS mesion recognition defence system to knock Silas unconscious. He and Donna regained the TARDIS, and the Horobot crashed Silas' ship into the desert to prevent his escape. (COMIC: Any Old Iron, Merchant of Menace)

At Donna's request, the Doctor took her to Hollywood in 2012, where they discovered Amelia Hubble, a creature capable of sucking thoughts and ideas out of the brain, had brought the town to a standstill. After falling under Amelia's control himself, the Doctor stopped her from destroying the last talent in the city, Alan Crawford, and allowed her to draw creative plasma energy from the internet, saving the celebrities she already claimed and restoring Hollywood. The Doctor and Donna returned to Hollywood a year later to find that Amelia and Alan had got married. (COMIC: Nightmare on the Boulevard)

Soon after, the Doctor and Donna visited a dairy farm in 1970 and defeated turbine-shaped plant creatures. (COMIC: Windswept)

While Donna was lost in the TARDIS, the Doctor decided to turn over the mattress of the bed William Shakespeare had given him to prevent the psychic hole in the bed from seeping through the memory hay. Wanting to test the bed, the Doctor found Donna and pushed her onto bed to see if there were any side effects. After nothing happened, the Doctor told Donna the history of the bed. (PROSE: Appendix - The Last Will)

Answering a distress signal in the Arctic Circle, the Doctor and Donna met Professor Renfrew and joined him and his team in their search for the corpses of ten miners. When Renfrew was killed, the Doctor discovered an Ice Warrior called Issaxyr was searching for a frozen Ice Warrior army. He discovered the Ice Warriors had planned to unleash a Spanish flu pandemic during World War I to weaken Earth. However, they were all killed by the Spanish flu. With his army dead, the Doctor returned Issaxyr to Mars to help rebuild the Ice Warrior civilisation. (PROSE: Cold) The Doctor and Donna then encountered the Cobalite Pandas. (COMIC: Ground Control)

Helping Martha
Whilst teaching Donna how to pilot the TARDIS, the Doctor received a call from Martha Jones, who led him back to UNIT in 2009 to investigate 52 simultaneous ATMOS-related deaths across the Earth. Alongside Private Ross Jenkins, the Doctor discovered the Sontarans were working with teenage genius Luke Rattigan to create ATMOS; they also replaced Martha with a clone, to keep them updated on the movements of the Doctor and UNIT. (TV: The Sontaran Stratagem) The sezerfine gas was emitted from ATMOS-equipped cars across the Earth to be used to breed more Sontarans for the war against the Rutans. After finding and freeing the real Martha, the Doctor used an atmospheric converter, built by the students at Rattigan's school for gifted children, to ignite the atmosphere, destroying the gas. The Sontarans' next plan was to simply conquer Earth. Rattigan, having been betrayed by the Sontarans, sacrificed his life to destroy the flagship with the converter, swapping places with the Doctor at the last minute.

While bidding Martha goodbye, the TARDIS' doors unexpectedly closed, and the TARDIS began dematerialising on it's own power, (TV: The Poison Sky) transporting the Doctor, Donna and Martha to the planet Messaline in the year 6012. There, DNA was stolen from the Doctor and replicated to produce Jenny, his biological "daughter". Initially critical of the girl due to her predilection for violence and reminded of the loss of his family, the Doctor came to feel for his daughter after much persuasion and help from Donna.

After the Doctor activated the Source, a terraforming device that had become a subject of mythology, Messaline became inhabitable and the war between humans and Hath on the planet ended. Before the Doctor could take Jenny aboard the TARDIS, she was shot by General Cobb, who had aimed for the Doctor but Jenny had stepped in his way, and died in her father's arms. Heartbroken, the Doctor became tempted to execute the detained general, but overcame the urge, and used his resistance in order to help found a new society on the planet. (TV: The Doctor's Daughter)

Having a fun time
After returning Martha home, the Doctor and Donna next traveled to Calcutta, where they were forced to stop Darac-7 from turning humans into Gelem warriors, (PROSE: Ghosts of India) to Planet 1, where the Doctor was hunted for sport by Sebastiene, (PROSE: The Doctor Trap) and stopped the robot prejudice Cult of Shining Darkness from carrying out their plans, but at the cost of the cultists being caught in an explosion. (PROSE: Shining Darkness)

The Doctor next foiled the Slitheen's plot to take control of the human race by using TV broadcasting, becoming a short-lived celebrity after getting the attention of BBC News, (COMIC: Just Another Thursday) and began experiencing illusions of Gallifrey on the desert planet of Baktek. (COMIC: The Baktek Illusion)

Working with Agatha Christie, the Doctor became embedded with a murder mystery at Eddison Manor in 1926. The Doctor discovered Arnold Golightly, a Vespiform/human hyrbid, was the murderer; he was mentally connected to Agatha by the Firestone, causing him to imitate her literature. Donna threw the gem into the lake, drowning Golightly, who went after it; the link damaged Agatha's short-term memory. The Doctor dropped her off at the Harrogate Hotel. He explained to Donna that Ms. Marple and Murder on the Orient Express were written because she gave Agatha the ideas, which her subconscious remembered. (TV: The Unicorn and the Wasp)

Arriving on the International Space Station in 2058, the Doctor formed an alliance with researcher Truman Truss to battle space insects called the Mange Mites. (COMIC: Attack of the Mange Mites!)

In Scunthorpe, the Doctor and Donna encountered a robot duplicate of Martha Jones, who had been created by one of the Doctor's enemies to entrap him. However, the Doctor reprogrammed her and left the robot to live a peaceful life on an alien world. (COMIC: Mad Martha)

Meeting River Song
The Doctor received a message on his psychic paper instructing him to go to the Library in the 51st century, where he met Professor River Song, a "very important" woman from his future, who had called him to help a team of archaeologists representing the Felman Lux Corporation to investigate the planet, which had been sealed off a century earlier with the message "4022 saved. No survivors." The group discovered the Library infested by Vashta Nerada, and the Doctor teleported Donna back to the TARDIS with the Library's teleporters, but she failed to make it, (TV: Silence in the Library) being "saved" into the Library's core instead. The Doctor realised that the four thousand and twenty-two people being "saved" meant they were also inside the core. River also gained his trust by revealing to him that she knew his real name, which deeply shocked the Doctor.

After the Vashta Nerada had consumed the last of River's team, the Doctor intimidated the swarm into giving him a single day to save the people in the Core before the Library detonated. Knowing he would not survive the process, River knocked the Doctor out and handcuffed him to a railing, sacrificing herself to boost the Library's memory, returning the people who were saved in the Library's core, including Donna. However, the Doctor, inspired by her faith in him, saved River by preserving her data ghost, saved in River's sonic screwdriver by his future self, into the core's virtual reality. (TV: Forest of the Dead)

Last exploits with Donna
The Doctor next took Donna to a leisure planet called Splendorosa, where they visited a floating city called Coral. Intrigued by the city, the Doctor went undercover at GeoCorp, the company responsible for the city's position in the sky. He came into conflict with the company's CEO, Volsairius Trefgar, after he and Donna uncovered a plot to "steal" Splendorosa by Trefgar and the war-like Sarriflex, who intended to transport the planet to a galaxy at war in order to use it as a weapon. The Doctor stopped them by disrupting their ships, bringing Coral City back to the land in the process. However, he and Donna, instead of being honoured for saving the population from a deadly war, were chased out of the city by a lynch mob, as the population had grown fond of "living in the sky". (PROSE: Grand Theft Planet!)

Whilst dealing with a small dinosaur situation, the Doctor found the time to give William Shakespeare a hand writing The Tempest. (PROSE: The Tempest - A Work in Progress)

The Doctor managed to prevent the Mandragora Helix from spreading influence through the internet, and then sent it out into space, confused and with memories missing. (PROSE: Beautiful Chaos)

On a visit to the Myolthen galaxy, the Doctor and Donna lost the TARDIS when it was swept away by a waterfall. Caught up in a raging waterfall themselves, the Doctor and Donna were saved by Jeb, a fisherman from Zentos 3. He, along with a group of intelligent bears, helped the Doctor to locate the TARDIS. (COMIC: Washed Away!)

Taking Donna to the ancient Acropolis of Xentha in Galaxy 12, the Doctor encountered the Titanoleum Army and foiled their plot to convert holidaymakers into Teglatrons. (COMIC: Titanoleum Tourists)

The Doctor and Donna visited the leisure planet Midnight, where Donna stayed at the leisure palace, whilst the Doctor took a four-hour ride on the Crusader 50 bus to the Sapphire Waterfall. However, the bus was attacked by an unknown entity, which possessed one of the passengers, Sky Silvestry, and eventually appeared to passed into the Doctor, 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 sunlight by the bus' hostess. (TV: Midnight)

After a turbulent ride in the vortex, the Doctor crashed the TARDIS at a science convention, where he and Donna witnessed Professor Eustace Krosson invent a wave-time vector detector that unleashed the Imago, parasites from the fourth dimension who devoured people's personal timelines. The Doctor tricked their queen into devouring Donna, a time traveller, which sent the Imago back to their own dimension and released everyone they had devoured, including Donna. (COMIC: Time Flies)

Visiting a garden centre at Christmas, the Doctor and Donna ran into a Snowdemon creature, and they helped the Pixees to put it on trial for its crimes. (COMIC: Frosty the Snowdemon)

The Doctor and Donna visited the planet Shan Shen, where a member of the Trickster's Brigade created an alternate universe around Donna while she had her fortune told; a universe where the Doctor died fighting the Empress of the Racnoss and Donna teamed up with Rose Tyler to correct the timelines. After Donna corrected the universe by killing herself in the alternative universe, she was able to gibe the Doctor a message from Rose, "Bad Wolf". (TV: Turn Left)

Reunions and farewells
Realising that the barriers between universes were breaking down, the Doctor rushed back to 2009 Earth, where he initially found everything was normal, but the planet vanished when he and Donna returned to the TARDIS. Finding no clue as to its location, the Doctor went to the Shadow Proclamation and learned twenty-seven planets had also been stolen, such as Adipose 3, Pyrovillia, and the Lost Moon of Poosh. Realising from Donna that bees had been disappearing from Earth, the Doctor connected the Migrant Bees of the Tandocca Scale to the Medusa Cascade, and concluded that the planets were there.

Fleeing the Shadow Proclamation, the Doctor and Donna arrived at the Medusa Cascade, only to find it apparently empty, until a phone call to the TARDIS allowed him to track down the Earth, which he discovered had been stolen by Davros and his new Dalek Empire; Davros had been saved from the Time War by Dalek Caan, at the cost of Caan's own sanity.

After landing on a ravaged Earth, the Doctor finally reunited with Rose, but he was mortally wounded by a passing Dalek before he could properly embrace Rose. After Jack destroyed the Dalek, the dying Doctor was taken into the TARDIS, where the pain of being shot forced him to regenerate (TV: The Stolen Earth) to heal himself, but the Doctor was able to channel the excess regenerative energy that would have changed his appearance into a bio-matching receptacle, his nearby severed hand, leaving him healed while remaining in his current form. (TV: Journey's End) This action did, however, use one of the Doctor's regenerations, leaving him with only one remaining, an action his successor claimed was due to "vanity issues". (TV: The Time of the Doctor)

The TARDIS was taken aboard the Dalek ship Crucible, where the Doctor, Rose and Jack were captured, but Donna was locked inside the TARDIS and the Doctor assumed her and the TARDIS lost when it was sent to the Crucible's Z-Neutrino core. As the Doctor's secret army gathered on the Crucible, Davros forced the Doctor to remember everyone who had died in his name and how he had turned all of his companions into weapons and willing murderers, which unveiled the Doctor's "soul".

However, before Davros' reality bomb could be detonated, a new Doctor, born from the severed hand when Donna touched it, arrived in the TARDIS, having piloted it away from being destroyed at the last second, to assassinate Davros, only for Davros to thwart the attempt, electrocuting Donna in the process. However, the meta-crisis made Donna part-Time Lord, with Davros' electrical attack transforming her into the DoctorDonna. The DoctorDonna then disabled the planet powered reality bomb to stop Davros from destroying reality itself and the Doctors and their companions overpowered the Daleks and sent the planets back to their original time and place. Whilst the Doctor worked on returning Earth home, the meta-crisis committed genocide against the Daleks, horrifying the Doctor. As the Doctor's companions retreated to the TARDIS, the Doctor offered to save Davros and Caan. Davros refused, hatefully denouncing the Doctor as "the destroyer of worlds", while Caan predicted that one of the Doctor's companions would still perish. The Doctor and company used the TARDIS to tow Earth back to its original location as the Crucible exploded.

The Doctor said his goodbyes to Sarah Jane, Martha, Jack and Mickey Smith before he left the meta-crisis Doctor in the Pete's World with the Tylers, hoping Rose would help him control his dangerous ways just as she had done to him in his previous incarnation.

Upon returning to his own universe, the Doctor was dealt another emotional blow as he was forced to remove all of Donna's memories of travelling with him, as her human mind was deteriorating due to her Time Lord part killing her. He returned Donna to her family, and told them they would have to make sure she never remembered him. After receiving comfort from Wilfred, the Doctor left to travel on his own. (TV: Journey's End)

Whilst grieving, the Doctor discovered Donna had recorded a message on Emergency Program One to say goodbye to him, knowing that one day she would be forced to leave him. (COMIC: The Time of My Life)

The lonely god
Still in mourning, the Doctor's mind was taken over by Es'Cartrss of the Tactire, who had been stuck on the Dalek Crucible and was unable to return home before his planet was returned, but the Doctor's link with the TARDIS forced them both into the Matrix, where the Doctor lost his memories. Assisted by a TARDIS impersonation of Martha Jones, the Doctor began recalling past adventures, eventually gaining control of his memories. The Doctor and his TARDIS, which was now impersonating most of the Doctor's past companions, fought Autons, Eight Legs and Clockwork Droids, and the Doctor seemingly killed Es'Cartrss, (COMIC: The Forgotten) only for the Tactire to survive. (COMIC: Dead Man's Hand) Having regained his memories, the Doctor decided to take a trip to the planet Barcelona. (COMIC: The Forgotten)

When an ancient alien parasite inhabited his mind, the Doctor lost his memory once again and took up residency in a boarding house owned by the Manns family in 1940. Working with Robert Mann, the Doctor discovered the parasite had inhabited the oak tree in the village and sucked it into the time vortex, regaining his memory and control over his mind. After this, he had dinner with the Manns and the local villagers. (PROSE: Number 1, Gallows Gates Road)

The Doctor arrived on Arcopolis to destroy The Fortress, a weapon that was left behind after the Last Great Time War. An alien force called the Eyeless attempted to steal the weapon themselves, but the Doctor successfully destroyed the weapon and defeated the Eyeless. (PROSE: The Eyeless)

The Doctor arrived in London on Christmas Eve, 1851, where he met a man calling himself "the Doctor" and his companion, Rosita Farisi, and assumed he was possibly his next face. However, after noticing inconsistencies, the Doctor discovered this man was actually a human named Jackson Lake, who had the contents of an infostamp about the Doctor imprinted on his brain after his wife was murdered by the Cybermen. Jackson aided the Doctor in stopping the Cybermen and their ally, Ms. Hartigan, who was betrayed and Cyber-converted into the CyberKing. After London was saved, Jackson was reunited with his son, Frederick, and invited the Doctor to share Christmas dinner in memories of everyone the two men had lost, an offer which was at first declined, but then accepted by the Doctor. (TV: The Next Doctor)

After dinner with the Lakes, the Doctor discovered Earth had been accidentally sold to the peace-loving Nin Confederacy by a human called Robbie, who had gained possession of the mobile of intergalactic estate agent Fliant Wormbleeder. Before he could save humanity from being exiled from their homeworld, the Doctor discovered two other hostile alien species, the Ssraarl and the Hoolox, had also bought Earth. He failed to reason with them, but allied with the Nin to stop them from firing missiles at Earth, and stopped a war from breaking out by finding a new homeworld for the three species. (COMIC: The Day the Earth Was Sold, The King of Earth) On a trip to a purple planet called Corah, the Doctor was arrested by Professor Slade and her crew on suspicion of murder. He found an energy-absorbing fugitive was turning the population to stone. On its trail, he and Slade's crew came across a lost Corah city that had been built by ancient Corah beings to combat the creature. Re-aligning their old machinery, he trapped the creature in the pools of Corah. (COMIC: The Guardians of Terror, The Rebirth of Corah)

Soon after, the Doctor began visiting Douglas Henderson throughout his life, because he was secretly a doomsday weapon created during the Last Great Time War. However, when Douglas was middle-aged, the Doctor was forced to take Douglas aboard the TARDIS as a group of aliens had began hunting him so that they could use him as a weapon. The Doctor used Douglas to drain the aliens' powers, and soon after, he reset Douglas and allowed him to spend the rest of his life on Earth. (COMIC: The Big, Blue Box)

(PROSE: The Slitheen Excursion)

When the TARDIS jumped a time track, the Doctor found himself on the planet Hurala during the Second Dalek War, where he encountered the crew of the bounty spaceship, the Wayfarer. The Doctor discovered that the Dalek empire had tried to exploit the Arkheon Threshold on the planet Arkheon, so they could have time travel. While on Arkheon, the Doctor encountered Dalek X and his flagship, the Exterminator. However, the Doctor destroyed Dalek X, the Exterminator and sealed the Arkheon Threshold. (PROSE: Prisoner of the Daleks)

Quest for the Eternity Crystal
After arriving on the Moon in the 30th century, the Doctor discovered a powerful device called the Eternity Crystal, created by the Karagulan society called the Darksmith Collective, for an undisclosed client. The Collective lost it. When they discovered it was located on the Moon, they sent an agent to collect it, but the Doctor had taken it to prevent them from having it. (PROSE: The Dust of Ages)

Whilst he was trying to understand the history of the Eternity Crystal, he travelled to the graveyard planet, Mordane, where its power had been tested by the Collective. However, the Crystal began to reanimate the dead bodies, but the Doctor managed to defeat them, and made them inanimate again. The Agent eventually arrived and took back the Crystal on behalf of the Collective. (PROSE: The Graves of Mordane)

In pursuit of the Agent and the Crystal, the Doctor arrived on the homeworld of the Darksmith Collective, Karagula. When the Doctor accessed the Darksmith's underground base via the Dark Cathedral, he retrieved the Crystal. In an attempt to understand the Crystal's purpose, he wanted to track down the person who initially constructed the Crystal, Brother Varlos, former member of the Darksmith Collective. (PROSE: The Colour of Darkness)

After tracing Varlos, the Doctor arrived in an underwater base on Flydon Maxima. However, the Collective dispatched a military force called the Dreadbringers to retrieve the Crystal, and the Doctor battled the native lifeform of Flydon, the Blaska. He discovered that Varlos had already departed from Flydon, and left behind his daughter called Gisella. Gisella told him that Varlos was the person who buried the Eternity Crystal on the Moon, because he realised that the Crystal was uncontrollable, and left it behind until he could find a way to destroy it. She told the Doctor that Varlos had travelled back in time, and settled in 1895 Paris. (PROSE: The Depths of Despair)

Arriving in Paris, the Doctor and Gisella found Varlos living under the alias Baron De Guerre, who was killed by a Time Vampire that was pursuing Varlos through the Time Vortex. He began investigating the deaths caused by the vampire, with the assistance of Inspector DuPont, who helped them discover that the vampire was an artificial alien, created by the crew of a spaceship to collect energy to refuel it. However, when it had amassed enough energy, it returned to the ship to discover the crew had already died. Reverting to its sole purpose of gathering even more energy, and without the means to discharge the energy, the creature became unstable. To defeat the vampire, Varlos gave his own life when he drained the vampire's time-energy using his own body, a mock Eternity Crystal and Gisella. (PROSE: The Vampire of Paris)

The Doctor began tracking the Agent across the Milky Way, and followed him to the Silver Devastation. The Doctor arrived in Devastation Hall during the Game of Death, an event devised by the Nocturn to lure humans. He found out that the Agent was destroyed by the Nocturn, Zalenby. The Doctor and Gisella departed and avoided being killed by the Nocturnes in the Game of Death. (PROSE: The Game of Death)

To find out who employed the Darksmith Collective to construct the Eternity Crystal, the Doctor arrived on Ursulonamex, where the Collective met with their clients. Expecting the planet to be lush and beautiful, upon arrival they found it had been scorched and charred to remove all trace of their arrival. The Doctor learnt from the survivors that evidence of their identity might exist in an observation station in orbit around Ursulonamex. On board the station, the Doctor found a Dravidian Hive, but the Doctor and Gisella escaped from them, and were unable to uncover any evidence about the Collective's mysterious clients. (PROSE: The Planet of Oblivion)

While in flight, the TARDIS was captured by the Shadow Proclamation, and the Doctor was put on trial where the Crystal was legally returned to Gisella. This was because Gisella was Varlos' daughter, and it was officially his property, so its ownership naturally passed on to Gisella. However, Gisella betrayed the Doctor, when she handed over the Eternity Crystal to the Collective. Although, she accidentally revealed the Darksmith's secret rendezvous point, the location where they were meeting their infamous clients. (PROSE: The Pictures of Emptiness)

The Doctor arrived in the designated location, London in 2009. Whilst he was there, he discovered the clients were really the Krashok. He also found out that Gisella was an android all along, who was created by Varlos, and who had been reprogrammed by the Darksmith Collective to give them the Eternity Crystal when she and the Doctor collected it. When Gisella and the High Minister of the Collective, Drakon, handed over the Crystal to the Krashok, Drakon was killed as soon as he fulfilled the deal, which broke the Collective's conditioning over her. (PROSE: The Art of War)

The Doctor discovered that the Krashok planned to use the Crystal to target their fallen warriors and to resurrect them, making them an invincible fighting force. They intended to detonate the Eternity Crystal unless the Doctor stopped them. To give him an incentive to do so, they trapped Gisella on their ship, aware that he wouldn't let her die, despite being an android that had been hoodwinked by the Collective. However, the Doctor eventually rescued Gisella, defeated the Krashoks and the Darksmith Collective, and destroyed the Eternity Crystal in the process. After the Doctor had completed his mission with the Eternity Crystal, he left Gisella behind to live out a normal life as an android. (PROSE: The End of Time)

The end is nearing
The Doctor travelled to London at Easter in 2009, investigating strange readings on a bus, where he met Lady Christina de Souza, an enigmatic jewel thief. After the bus was hurtled through a wormhole to San Helios, the Doctor cooperated with Christina to return the bus and its occupants to Earth.

Phoning UNIT to stabalise the wormhole, the Doctor and Christina discovered a swarm of metallic alien stingrays had reduced San Helios to a baron wasteland and were heading to the wormhole to invade Earth. Converting the bus into a hovercraft, the Doctor piloted the bus through the wormhole, and had UNIT's scientific officer, Malcolm Taylor, close the wormhole behind him.

Before leaving in the TARDIS, the Doctor rejected Christina's offer of companionship, stating he lost everyone who traveled with him and swore never to go through the heartache again. As he turned to leave, Carmen, a low level psychic on the bus, offered a prophecy; "Your song is ending, sir. It is returning. It is returning through the dark. And then, Doctor? Oh, but then... he will knock four times." As Christina was arrested for multiple thefts, the Doctor used his sonic to aid her escape, and she took off in the bus. When the Doctor was about to be arrested for helping Christina, he entered the TARDIS to "arrest himself" and left, bidding Christina goodbye. (TV: Planet of the Dead)

The Doctor arrived in the 26th century to investigate the appearance of Sontarans and Rutans on the planet, Chelsea 426, during the Chelsea Flower Show. (PROSE: The Taking of Chelsea 426)

The Doctor foiled an Auton invasion at the Hyperville shopping complex in 2013, with the help of Kate Maguire. (PROSE: Autonomy)

The Doctor caused a change in the timeline that resulted in Carla disappearing, and, per Carla's request, the Doctor began searching for her. (PROSE: The Haldenmor Fugue) He theb encountered the Krillitanes in Worcester in 1140, and defeated them with their own oil. (PROSE: The Krillitane Storm)

The Doctor discovered the Trickster was plotting to end Sarah Jane and the Bannerman Road gang's alien fighting by planting Peter Dalton as a love interest for Sarah Jane, knowing she would retire after Dalton proposed to her.

Crashed the wedding, Sarah Jane and Dalton were taken by the Trickster, and the Doctor and the Bannerman Road gang were teleported to a nether realm, trapped in a single second away from Sarah Jane. The TARDIS' rescue of the Doctor gave Clyde the power to control artron energy by mistake, which Clyde used to weaken the Trickster, while the Doctor informed Sarah Jane what needed to be done. Dalton sacrificed himself to destroy the Trickster, leaving Sarah Jane alone and heartbroken.

After the world was restored, the Doctor visited 13 Bannerman Road and let Sarah Jane's friends look inside his TARDIS, after which he said farewell to Sarah Jane, asking her to never forget him and promising her he would see her again. (TV: The Wedding of Sarah Jane Smith)

No song should end too soon
Arriving in 21st century Brooklyn, the Doctor met a young Mexican-American woman named Gabriella "Gabby" Gonzalez, who loved art. Together, they fought off an invasion of Cerebravores on Halloween/Day of the Dead, which resulted in the complete and utter destruction of Gabby's family laundromat. Thought not wanting to face more heartache by having a companion, the Doctor decided to follow the same rule as when he took Martha on - one trip. (COMIC: Revolutions of Terror) For her first journey in the TARDIS, the Doctor took Gabby to the No-Gallery of Ouloumos. There they discovered that a block transfer artist, Zhe Ikiyuyu, was missing from the gallery, having exiled to her private moon. While investigating in her retreat, Zhe's apprentice, in conflicting male and female forms, menaced the Doctor and Gabby before the real Zhe awakened from her stasis and pulled them into her, they having been conflicting aspects of her personal psyche. Impressed by Gabby's skills in the crisis, the Doctor decided to allow her to be a full-time companion. (COMIC: The Arts in Space)

Landing in World War I, the Doctor once more faced the vile Weeping Angels; as the war was killing humans in large numbers, the Angels were desperate for time energy to feed on. They succeed in capturing the TARDIS, temporarily making Gabby believe it had been destroyed by a bomb; she also quickly fell for one of the soldiers. Working together with the soldiers, the Doctor was able to recover the TARDIS and bury the Weeping Angles in mine. However, by 2007, a Weeping Angel hand was sticking out of a graveyard filled with their victims. (COMIC: The Weeping Angels of Mons)

The Doctor attempted to land on a planet with desert-like conditions, but landed in the rainy season by mistake. He decided to show Gabby the Laundro de-mat, which would restore their clothes to how they were before getting muddy. Unfortunately, he forgot his sonic screwdriver in his jacket, resulting in it and the TARDIS's telepathic field creating a mud avatar that returned the sonic to him. However, the sonic appeared to have shorted out the de-mat machine, as his pinstripes were swapped with the flower patterns on Gabby's shirt. (COMIC: Laundro-Room of Doom)

The Doctor and Gabby returned to New York on a "flying visit". As Gabby met up with her family, the Doctor discovered a mysterious increase in noise pollution throughout the city. He used the sonic screwdriver to deduce the noise increase was a cry for help from the Echoes, beings of living sound that were being hunted by Shreekers, who were enslaving them to harvest their energy for weaponry. Escaping back to the TARDIS on a moped, the Doctor and Gabby traveled to the Empire State Building, where the Doctor began tuning the mass to absorb the sonic chaos of the Echoes and expel it at the Shereeker ship. However, a Shreeker knocked the Doctor away. As it taunted Gabby, Gabby grabbed the screwdriver and used it to finish the calculations, destroying the Shreekers and their ship. The Echoes flew away, thanking Gabby for freeing them. (COMIC: Echo)

The Doctor and Gabby prepared to set off again, but the Doctor recieved a cloaked signal on his sonic screwdriver. He used Gabby's phone's GPS to pinpoint the signal, learning it was from an auction in the city. He converted Gabby's phone to a superphone and went to the auction alone while Gabby met with her friend Cindy. At the auction, the Doctor became suspcious of a mysterious artefact that had already been auctioned off. As the Doctor attempted to send a message to UNIT to stop the auction, he was attacked by a woman called Cleo, who had noticed his suspicion and demanded his help in aquiring the artefact. The Doctor agreed and the two tracked the artefact to an apartment in the east upper side of Manhattan. There, they found it was in the posession of movie star Dorothy Bell. Cleo took control of the artefact and revealed it was used to regress age, using it on Vivian, Dorothy's assistant, regressing her to a baby. When the Doctor tried to stop her, Cleo used the artefact on him, regressing him back into his previous incarnation.

Dorothy fought for control over the artefact with Cleo, breaching the time field and causing a burst of energy that knocked everyone out. Cleo awoke and escaped with the artefact. The Doctor woke up to find that his and Vivian's ages had been restored, but Dorothy was dead. Vivian revealed that she was aware of the artefact's properties and had hoped to use it to preserve Dorothy's life. Dorothy's body, which was still connected to the artefact's power field, suddenly began levitating as Gabby and Cindy entered the apartment, having tracked the Doctor via superphone. Dorothy's body let out pulses of energy, and when it stopped, she had been regressed in age and had powers of matter transmutation. (COMIC: The Fountains of Forever)

The regressed Dorothy flew away, and Vivian guessed she would be heading to St John's Hospital, where Dorothy had wanted to see the finished construction of its new wing. Urging her to stay behind for Dorothy's trust, the Doctor, Gabby and Cindy rushed to the hospital, to see Dorothy was using her new powers to build the hospital's wing. As Cindy tried to talk to Dorothy, the Doctor was approached again by Cleo, who had brought her associates, Erik and Han, from her religious cult with her. They were under the belief the artefact could be used to communicate with the gods. The Doctor realised that Dorothy had become a quantum harvester. Dorothy flew away in grief, believing that there were no gods, taking Gabby with her. The Doctor, Cindy and the cult decided to team up to track her down.

They tracked Dorothy to the Empire State Building, where she was using her powers to rebuild the city. A mysterious force captured the Doctor, Cindy and the cult and sent them to a vessel. The Doctor deduced that the gods were the Osiran and that the vessel was a remnant of their civilization. The force, calling itself the Seeker, detected Gabby and Dorothy and beamed them to the vessel, but then dispensed the Doctor and Cindy back on Earth. Cindy demanded she be able to help, so the Doctor reluctantly agreed to take her to the TARDIS. They traveled to the Osiran mothership, which was where the vessel was located. They exited to find Gabby, Dorothy and the cult frozen and suspended, and were confronted by Anubis. (COMIC: Spiral Staircase)

Anubis's servant deduced that Dorothy, with her new powers, was the manifestation of the key of Horus. Anubis revealed he was trying to build a gateway to follow his fellow Osirans to a four-dimensional universe. The Doctor, however, knew that the gateway would create a catastrophic ripple effect that would destroy the universe. Erik, feeling betrayed from his beliefs, attacked Anubis. The servants responded by killing Hanif. The Doctor healed Anubis of his injuries in a bid to make him see sense, but Anubis still planned on going through the gate. As the misalignment of the circle of transcendence and the mothership widened, the Doctor finally persuaded Anubis to delay his journey by reminding him he had defeated his father Sutekh and that he was nothing like him. Anubis agreed to delay his journey by five thousand life cycles, and Dorothy decided to stay behind with him. The Doctor returned Cindy, Cleo and Erik to Earth and set off for further adventures with Gabby. (COMIC: Sins of the Father)

Multi-Doctor event
The Doctor and Gabby visited 1923 Paris. where they thwarted a Cyberman plan to raid the French Gold Reserves. Passing a cafe in the aftermath, the Doctor asked Gabby to order some crepes while he disposed of a leftover Cyberman head. After disposing of the head, he returned to the cafe to discover Gabby was in a meeting with his future companions Alice Obiefune and Clara Oswald. He broke into their conversation, just as his next incarnation did as well. The Doctor scanned him with the sonic to verify he was indeed his next self, just as the Twelfth Doctor entered too. The Tenth Doctor was confused by his presence, as he knew he only had one regeneration left. He argued with this older Doctor until they brushed fingers and sparked the Blinovitch Limitation Effect, spawning Reapers.

Escaping the Reapers, the Doctors and companions navigated the TARDIS to expel them. Clara revealed that the three Doctors had had an encounter on the planet Marinus in the circumstances of a catastrophic event. Despite Gabby's urging, the Tenth Doctor decided to go to Marinus to see what the event was, as did the Eleventh and Twelfth Doctors. Once there, they were attacked by Voord and split up through a maze. The Tenth Doctor found himself running with Alice, and they all met up back at the middle, where a continuity bomb detonated and turned all six of them into time ghosts. As time ghosts, the three Doctors were all shown glimpses of their possible futures: the Tenth Doctor saw a timeline where he allowed Wilfred to die in a radiation chamber and went on to become the Time Lord Victorious. They also saw a future for the Eleventh Doctor, where he had settled down with River in a time-frozen world, and eventually came to a future for the Twelfth Doctor, living as a ragged hermit in the TARDIS after being betrayed.

The Doctors all decided to converge back on this future, as it seemed the most secure. The Twelfth Doctor touched his alternate self, bringing all the Doctors and companions back into being. The alternate Twelfth Doctor recognised everyone and offered them a lift. They arrived in a futuristic city, where the Voord reappeared. However, the alternate Twelfth Doctor revealed that he was their leader and was taking them all prisoner. Having enjoyed his life with the Voord, he wanted to ensure it would indeed happen by altering the Twelfth Doctor's mind to make him fall out with Clara after their betrayal, while wiping the other companions' and Doctors' memories. The Tenth and Eleventh Doctors made a diversion that allowed Gabby and Alice to escape, while they, the Twelfth Doctor and Clara began to have their memories altered. (COMIC: Four Doctors)

The Crimson Hand
The Doctor re-encountered time-travelling businesswomen Majenta Pryce when he went undercover as a medical doctor at the Thinktwice Orbital Penitentiary, where she had been imprisoned thanks to his meddling in her "Hotel Historia" business. However, the harsh regime and crude psychological methods of the prison left Majenta with no memory of the Doctor or her life before their first meeting. The Doctor restored Majenta's memory of him, but could not restore anything else beyond their first encounter. Together, they uncovered the truth behind Thinktwice; it was being used by the Memeovax, who fed on the prisoners' memories. When one of the Memeovax tried to invade Majenta's mind, she unleashed a blast of power that destroyed all the Memeovax in Thinktwice Prison. Afterwards, the Doctor was ordered into helping Majenta to resolve her memory issues, reluctantly taking her aboard the TARDIS. (COMIC: Thinktwice)

Trying to take Majenta to Panacea — a healing world, where he planned to solve Majenta's memory problems, the Doctor instead landed the TARDIS in Stockbridge, where he was reunited with his old friend Maxwell Edison and saved Stockbridge village from the Lokhus of the Zytragupten. After this, the Doctor once again asked Maxwell to travel with him. Maxwell declined, instead opting to protect Stockbridge from aliens. (COMIC: The Stockbridge Child)

The Doctor and Majenta arrived at an apparently abandoned house on the edge of the Proxima System. The Doctor discovered a holographic party run by a digitised avatar of Wesley Sparks, founder of Sparktech. As events from decades before replayed in holographic form, the Doctor was astonished to learn Majenta had been a guest at the party as Wesley's best friend, business partner and fiancée. The real Majenta explored the house. She came upon the real Wesley Sparks, now a desiccated cyborg who had gone insane as he preserved himself with bionic parts, waiting for Majenta to return from "pressing business". He attempted to force Majenta into marrying him, but she was saved by the Doctor and Wesley's avatar, still the dignified host and gentleman he had been. Damaged in battle saving Majenta, the avatar begged Majenta to remember their lives together. Majenta tearfully broke down and embraced the avatar as it died. (COMIC: Mortal Beloved) Still trying to take Majenta to Panacea, they got sidetracked and landed in Sydney, where they were taken into custody by UNIT's Australian branch. The Doctor was surprised to find the UNIT officer was Majenta's old confidante, Fanson, disguised by a perception filter. Fanson was now in the thrall of the Doctor's previous foe, the Skith Leader, who was secretly helping Fanson infiltrate the UNIT operation. Majenta was captured by the Skith General's rival forces, who were surprised to find themselves unable to access her mind. The Skith elected her as the perfect pilot for the prototype timeship (or SKARDIS), a replica of the Doctor's TARDIS, and converted her into a Skith Queen. While she was in this form, the Doctor convinced her to turn on the Skith and help UNIT destroy their ship. As the Skith ship fell, Fanson revealed that he was responsible for erasing her memory to spare her agony. Fanson died from injuries sustained at the hands of the Skith General, and the Doctor and Majenta fled, finally beginning to warm to each other. (COMIC: The Age of Ice)

The Doctor and Majenta next visited New Old Detroit, a planet in the Proxima System. There, they solved the final case of low-life private eye Johnny Seaview and wrested control of the World Bomb from a corrupt Alpha Centauran The Doctor triggered the World Bomb, transforming the slums of New Old Detroit into a world mapped on his memories of England. (COMIC: The Deep Hereafter)

The Doctor next took Majenta to Graveworld 909, where they stopped Prespero, the guardian of the planet who had taken away the population's speech following a galactic war. (COMIC: Onomatopoeia) After that, the Doctor took Majenta to see the play The Mousetrap. In the London Underground they found "ghosts" saved by a being known as Mnemosyne. After they defeated Mnemosyne and after receiving another prophecy about his approaching demise, the Doctor decided to stick to his "no companions" rule and intended to take Majenta to Panacea. Before he could take her there, a fleet of ships surronded Earth, having finally tracked down him and Majenta. (COMIC: Ghosts of the Northern Line)

Majenta and the Doctor tried to escape in the TARDIS, but this failed as Intersol launched a tractor beam. The Doctor was captured and tortured by Finn Dargo and learned that Majenta was a member of the Crimson Hand, a highly dangerous criminal organisation. Majenta was mind-probed by Intersol's computer, Justice, and then attacked by her old cellmate, Zed. The Doctor convinced Zed into becoming his ally, helping him escape and save Majenta. However, the four remaining members of the Crimson Hand arrived, having followed the TARDIS around the universe. They killed most of Intersol's staff and took Majenta over again. As she was taken over, she teleported the Doctor and his TARDIS in a pocket dimension, making her Crimson Hand friends believe that she had turned the Doctor to ashes.

After the Crimson Hand members seized control of the whole universe, Majenta restored her homeworld of Vessica. It had been a planet of immense poverty; this changed when she used the Crimson Hand to make the planet rich again. The population rebelled against her and she brought the Doctor back into existence. After resisting the urge to use its power to bring back everyone he had lost, the Doctor and Majenta finally destroyed the Crimson Hand at the cost of Majenta's life. The Doctor resurrected her and placed her in the restored New Old Detroit. As long as the Doctor remembered her, she would stay alive. With his mission to help Majenta complete, the Doctor was left alone again. (COMIC: The Crimson Hand)

Meddling with time
The Doctor attended a celebrity party in Hollywood in 1926, where he met Archie Maplin, a young actress called Emily Winter and a runner called Matthew Finnegan. He drew the attention of Maximilian Love and Mr Leo Millar, two Terronites, who planned to transfer the hopes and dreams from young actors, such as Maplin and transplant them into themselves, because they were actors on Terron V. Offering himself for Maplin's safety, the Doctor's memories were too much for them, and inadvertently set fire to the building. The Doctor got them all safely out the building before it exploded. Outside they saw Miller escaping, but was eventually arrested by the police. As the Doctor headed back to the TARDIS, Matthew and Emily asked if they could join him, but he refused. However, as he was about to enter his ship, a temporal vortex opened up. From it emerged Judoon and a Shadow Architect, who arrested the Doctor for interfering in fixed points in times. (COMIC: Silver Scream)

The Doctor was placed on trial by the Shadow Proclamation for transgressing the Laws of Time and saving Emily's life when she should have died when the building was on fire. Krillitane leader Mr Finch was the Doctor's prosecutor and the Advocate was defence, but the Advocate was later killed. The Doctor was sentenced to imprisonment on Volag-Noc, and during the journey met a Draconian, a Sontaran and an Ogron. The Doctor's party took control of the ship. After this, the Doctor learned that his trial was set up to uncover Finch's plot, but he also found out that Finch was from a shapeshifting race called the Gizou, in disguise. The Doctor returned to 1926 Hollywood to collect the Terronite Transference machine, used to extract memories from the Doctor's mind. While there, he decided to break his "no companions rule" by inviting Matthew and Emily to travel with him, unaware that the Advocate had survived and was on the hunt for the Terronite machine in the Doctor's possessions. Before leaving, the Doctor received the "he will knock four times" prophecy again from the Judge responsible for his capture and trial, reminding him of his approaching death. (COMIC: Fugitive)

The TARDIS was invaded by aliens called the Acari led by the Advocate, and were intent on killing the Doctor. The breach of the TARDIS by the Acari spaceship forced the TARDIS interior to rearrange itself, displacing the console room, and risking implosion. Since the Doctor was psychically linked to the TARDIS, the trauma of having the Acari ship aboard caused the Doctor to undergo mental instability and his past selves began to bleed through. The Advocate placed doubt into Matthew's mind about the Doctor's morality by urging him to read the secret diary previously belonging to Turlough. A being called the Tef'Aree appeared to Emily in the TARDIS. Emily helped the Doctor save the ship, and the Acari ship separated from the TARDIS, but not before the Advocate stole the Terronite technology. (COMIC: Tesseract)

The Doctor was summoned to Greenwich Park by Martha Jones and Captain Erisa Magambo working on behalf of UNIT, and claimed that the trees were attacking people. The tree trunks were marked with Enochai symbols, a language invented by mathematician and magician John Dee to converse with angels. The Doctor realised these "angels" were trapped beneath the observatory, but emerged through the trees in the park. The Doctor headed into the passages beneath the park to communicate with the "angels". In actuality, the aliens were waiting in suspended animation for the Doctor to free them. Believing the Enochai's story, the Doctor set them free, but it was a trick. John Dee trapped them, but they became free to take over all of the trees and conquer the Earth.

The Enochai realised the Doctor didn't remove the force field trapping it, so they threatened Emily. The Doctor and Emily escaped, but plunged down a hidden shaft into an ancient cavern where they discovered a stripped down colony ship containing thousands of Enochaia in stasis. The Advocate arrived and opened the stasis pods, releasing the Enochai. The Enochai trapped Central London in a force field. The Advocate appeared to Martha and proposed a way of ending the crisis, by striking at the Enochai ship and planting a bomb in it. Martha found Emily and the Doctor, and they confronted the Advocate, but Magambo refused to allow him time to develop an alternative solution to the Enochai threat and insisted on following the Advocate's plan. When he resisted this option, she arrested the Doctor.

Martha and Emily rescued the Doctor. The Doctor arrived and launched the Enochai ship into space, which drew all the Enochai up with it, and removing the force field. The Advocate's bomb was no longer needed, but the countdown was accidentally started and the ship would explode, leaving a gardener called Mr Crane trapped inside, but the Doctor could do nothing to save him. The Advocate used Crane's death to finally destroy Matthew's faith in the Doctor and Matthew elected to leave the Doctor, and travel with the Advocate instead. After solving the crisis, the Doctor and Emily departed from London. (COMIC: Don't Step on the Grass)

After several adventures in the TARDIS, the Doctor and Emily arrived at the Shady Grove Rest Home in the 21st century where an old man named Barnaby Edwards celebrated his birthday. Although the Doctor didn't recognise him, Barnaby insisted he travelled with the Doctor when he was a young man. The Doctor gave Barnaby an envelope and told him to guard it with his life. He returned it to the Doctor before dying, contented. The Doctor wasn't upset - he knew he'd have the pleasure of meeting Barnaby as a young man sometime in his own future. Inside the envelope was the charred remains of Turlough's diary and a warning that Matthew Finnegan was in danger. The Doctor and Emily headed off to find him and to stop the Advocate's plans. (COMIC: Old Friend)

While exploring a war-torn planet, the Doctor and Emily encountered Robert Lewis and his colleagues: Eliza Cooper, Professor Alexander Hugh and Annabella Primavera from Oxford University in 1906. They were working for Torchwood, and were testing a time machine created from cannibalised alien technology, which inadvertantly transferred them through time and space to this planet. Their group was captured by inhabitants of the planet, called the Soul Free, who had been fighting with other inhabitants called Terror Farmers for thousands of years. The party, led by the Soul Free were led to a temple called Kol'Ne Wah, by the Gizou who impersonated Mr Finch during the Doctor's trial by the Shadow Proclamation, whose real name was Lau'Tan, and had been working against the Advocate since the trial.

They were attacked by the Terror Farmers, causing Annabella's death. Lau'Tan disguised himself as the Doctor and captured with Emily. The Doctor led the remaining group to the temple, where he discovered a lost expedition, who made contact with the Tef'Aree, who Emily had encountered in the TARDIS during the Acari incursion, and were in fact humans given a terraforming device with which they hoped to make the colony planet self-sufficient. After this discovery, the Doctor realised that the name "Terror Farmers" was a corruption of Terra Firma, likewise with the "Soul Free" (Sol Three).

The Doctor discovered that the Advocate planned to use Matthew's human DNA to reactivate the terraforming device which would wipe out the whole planet. Matthew and the Advocate teleported up to the orbiting terraforming device and the Doctor followed in the TARDIS. As the Advocate tried to get Matthew to activate the terraforming device, he finally revealed his true allegiance to Lau'Tan. She shot him Matthew, and used his palm to activate the device. The conflict on the ground between the Terror Farmers and the Soul Free was brought to an instant end as the device began to destroy everything on the planet.

Robert Lewis was destroyed by the terraforming beam, while Emily was saved from the blast by Turlough’s diary. The force field around the colony ship couldn't be repaired, but Lau'Tan realised it could be replaced. He transformed himself into a device to replace the damaged component and restart the shields while Emily got everyone safely inside. Matthew distracted the Doctor, grabbed the Advocate and deactivated the terraforming controls, but it backfired. Both Matthew and the Advocate died instantly, but both their minds merged together into a fifth-dimensional being called Tef'Aree. The Tef'Aree previously gave the Earth colonists the terraforming technology, revived the Advocate and had generally manipulated events surrounding the Doctor, so that he could bring about his own creation. When the Doctor tried to scold the Tef'Aree, it vanished. Before deactivation, the terraforming beam destroyed the forcefield equipment, in turn, destroying Lau'Tan. However, many of the Soul Free and Terror Farmers were saved by his action, being protected by the forcefield. Eliza elected to remain and help to rebuild the planet, and build diplomatic relations between both factions. Upon discovering that the planet was called Terron V, he realised that both groups would unite, and eventually become the Terronites, who the Doctor fought in the form of Maximilian Love and Mr Leo Millar in Hollywood in 1926.

The Doctor took Professor Hugh and Emily back to 1906 Oxford in the TARDIS. There he explained that Annabella Primavera, like Emily, was a fixed point in time, but while Emily was supposed to have died, Annabella was supposed to have lived. Therefore, Emily had to live on Earth, and take her place to mend the web of time. Before she departed, Emily gave him Turlough's scorched diary, which he would later give to Barnaby Edwards, and the Doctor left for a trip to Mars. (COMIC: Final Sacrifice)

On his trip to Mars in 2059, the Doctor met the crew of Bowie Base One led by Adelaide Brooke, who he greatly admired. He knew the crew of Bowie Base One would die, as it was one of the most crucial events in humanity's expansion through the universe. He learned that the crew died due to the Flood, which possessed six of them. He was initially unwilling to interfere in events due to his belief that the event was a fixed point in time (Adelaide's death causing her grand daughter to be inspired and explore the stars), but he became integrated in the events of Bowie Base One. He attempted to leave, but his resistance towards helping was eroding fast as the screams of the Bowie Base crew reminded him of the billions of deaths he had lived through and what it had left him with.

Enraged and driven mad by his power as the last of the Time Lords, he saved Adelaide and her last crew-members, Mia and Yuri, and took them back to Earth. Adelaide was furious at the Doctor's interference and scolded him for thinking himself above obeying history's course. Confident that the laws of time were his, the Doctor sent Adelaide home. In her home, she committed suicide: the events of Bowie Base One shaped the same timeline, but with Adelaide dying on Earth instead of Mars. Distraught at the results of his actions, he berated the impossible task of changing history and began to ponder his own end when a vision of Ood Sigma appeared before him. Crying, he fled into the TARDIS, the Cloister Bell ringing. Seething with self-hatred, he cried a defiant "No!", activated the TARDIS - and began running from his fate. (TV: The Waters of Mars)

The Doctor spent an unknown amount of time avoiding answering the Ood's summons, during which the Doctor saw the phosphorous carousel of the Great Magellan Gestadt, saved a planet from the Red Carnivorous Maw and named a galaxy, "Alison". (TV: The End of Time)

Saving Gallifrey
The Doctor discovered Zygons had infiltrated 1562 Earth, and believed Queen Elizabeth I to be one of them. To help track them down, he constructed a device that went "ding" in their presence, along with many additional features.

While having a picnic with Elizabeth, the Doctor proposed to her as a ploy to expose the Zygons, believing his theory to be correct when she eagerly accepted, but discovered that it was his horse that was the Zygon, and also realised that he had just got engaged to the real Queen of England. After the Zygon took on Elizabeth's form, and with his device unable to tell them a part, a time fissure appeared and a fez came through it, followed by his next incarnation. The Doctor ordered both Queens away and he and the Eleventh Doctor tried to use their sonic screwdrivers at the same time to reverse the polarity of the wormhole, only for the War Doctor to enter the scene. One of the Queens, which the Doctors believed to be the Zygon, returned with royal guards and, after the Eleventh Doctor gave instructions to Clara Oswald, the Doctors allowed themselves to be captured and taken to the Tower of London.

At the Tower, the Eleventh Doctor scratched the activation code for a vortex manipulator into a pillar, which Clara used to save them; the door having been left open. The Queen took them to show them that the Zygons put themselves into stasis in paintings to take over the planet at a future date and revealed herself to be the real Queen who was showing them so that they could defeat the Zygons in the future.

(COMIC: To Sleep, Perchance to Scream)

Following Princess Cilia's disappearance at the end of the Ulians' war with the Quintani, the Doctor chose to help. However, once the Doctor found Princess Cilia's ship, she wasn't on board. The Ulian robots on board attacked the Doctor, accidentally shrinking him to the size of a doll. The Ulian robots traced Princess Cilia to the approximate area, but only knew that she was in the vicinity of a Christmas tree. They sent shrunken-down versions of their robots, wrapped in Christmas packages to send to every doorstep on that region of Earth. The robots inadvertently shrunk down the Doctor and put him in a package.

Mason Valentin, having opened the package early, discovered the Doctor wasn't a doll, but a living being. As the Doctor awoke, he was dazed and suffered from amnesia. After learning of packages delivered all across Mason's area, the Doctor offered Mason to save the world with him. The Doctor and Mason went into Ana Comparetto's house, and the Doctor prematurely awoke a shrunken Ulian robot with the sonic screwdriver. The robot, thinking it had found the lost princess, transmatted Ana back to Cilia's ship. The Doctor and Mason used the robot's "magic wand" to fire a transmat beam to board the ship.

On board the ship, the Doctor released Ana from her cell. The Doctor, remembering what had happened to the princess, told the robots that Ana wasn't the princess, and though their methods of tracking the princess were scrambled, he could find her easily.

Ana told Cilia the war was over, and the Doctor told her to order the robots to send her back to Ulian Alpha. (PROSE: The Doctor on My Shoulder)

The final sanction
After meeting with the Ood on Ood Sphere, the Doctor was told that a shadow was falling across creation, which was somehow connected to Donna Noble and her grandfather, Wilfred Mott. He also learnt of a plot to resurrect, and failed to stop it. The Doctor discovered the Master living in the wastelands of London. He tried to confront him, only for the Master to evade the Doctor when he reunited with Wilf. That night, the Doctor tracked down the Master once again, only for the Master to be abducted by Joshua Naismith's private army, and when the Doctor attempted to stop them, he was knocked out.

After he recovered, the Doctor contacted Wilf, who informed him of Naismith and went with him in the TARDIS to the Naismith Manor. In the Manor's basement, the Doctor used his sonic screwdriver to unveil two Vinvocci, Addams and Rossiter, who informed him of the Immortality Gate's true purpose. The Doctor rushed to stop the Gate's activation, but was unable to, and the Master turned the entire human race into copies of himself.

After being taken prisoner, Wilf and the Doctor were rescued by the Vinvocci, who took them to their ship in Earth's orbit, which the Doctor took offline to stop the Master finding them. Realising the Master was planning to rescue the Time Lords from the Time War using a White-Point Star, the Doctor took the gun he initially refused from Wilf and piloted the Vinvocci ship back towards the Naismith Manor, where he crashed through the manor's glass roof. However, he was unable to stop the Master from using the Star and The Drumming to create a link to Gallifrey, which allowed Lord President Rassilon and the High Council to escape Gallifrey.

Rassilon undid the Master's conversion of the human race, as Gallifrey appeared in the Earth's sky and began tearing open the time vortex. Torn between killing the Master or Rassilon in cold blood, the Doctor, upon seeing a familiar face, targeted the White-Point Star, severing the link, condemning the Time Lords to the "hell" of the last day of the Time War. Rassilon tried to kill the Doctor, but he was saved by the Master, who attacked Rassilon with his energy blasts, which resulted in the Master being sent back into the Time War with the Time Lords. (TV: The End of Time)

Saving Wilf
With the Time Lords and the Master gone, the Doctor was relieved that he had survived his supposed death at Rassilon's hands, but his victory was short-lived when he heard the four knocks. They came from Wilf, who was trapped inside a radiation control booth which was about to be flooded with radiation. The Doctor quickly realised that the only way to save Wilf was to switch places with him, and be subjected to the radiation bust himself. At first angry about the terrible things the universe rewarded him with and nearly considering Wilf's pleas to leave him, the Doctor could not bear to sacrifice one life to prolong his own after going through so much to stop men willing to take the lives of millions to do the same. Determinant, he released Wilf and received the fatal level of radiation.

After the regenerative process started, the Doctor returned Wilf home, and then went to receive, what he called, his "reward." (TV: The End of Time)

The Doctor's reward
The Doctor visited the companions of his previous incarnations, seeing how they got on after they left the TARDIS. (TV: Death of the Doctor) The Doctor visited Heather McCrimmon and Wolfgang Ryter, four years after they had left him, (COMIC: Lucky Heather) watched Jo Grant sail down the Yangtze River in a tea chest, (TV: Death of the Doctor) and, after years of searching for what became of Carla in the new timeline, he finally located her. (PROSE: The Haldenmor Fugue)

The Doctor visited Martha Jones and Mickey Smith, now married and working as freelance alien fighters, saving them from a Sontaran. He went to Bannerman Road where he prevented Luke Smith from being run over by a car and waved goodbye to Sarah Jane Smith, as he had promised on their last meeting. He then travelled to the Zaggit Zagoo bar, where Jack Harkness was drowning his sorrows following the 456 incident. The Doctor passed a note to Jack reading, "His name is Alonso", setting Jack up with Midshipman Alonso Frame, and he departed as the two began flirting.

The Doctor then went to a bookstore where Verity Newman, the granddaughter of Joan Redfern, was signing copies of her book, A Journal of Impossible Things, (TV: The End of Time) which was based on the journal the Doctor had written during his time as John Smith. (TV: Human Nature) The Doctor had Verity sign his copy, and she realised he was the man who her grandmother fell in love with. The Doctor asked Verity if Joan had been happy in the end, which she confirmed, but he refused to answer her question of if he was.

He then encountered Donna's father, Geoff Noble, before the man's death, and borrowed a pound from him. He then went to the future and used that pound to purchase a winning lottery ticket. He attended Donna Noble's wedding to Shaun Temple, and asked Sylvia Noble and Wilf to give Donna the triple rollover-winning ticket as a wedding gift, saying a final goodbye to Wilfred, who was left crying at the Doctor's loneliness and impending death as he gave the Doctor a final salute.

To finish his long "reward", the Doctor travelled to the Powell Estate, on 1 January, 2005, where he watched 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" with tears in his eyes as he spoke. (TV: The End of Time)

Final death
After Rose left, the pain of regeneration overwhelmed the Doctor, and he collapsed in the middle of the Powell estate. Ood Sigma then appeared and told him that while his song was ending, his story never would, and that the universe would sing him to his sleep.

Having only the strength to reach the TARDIS, the Doctor piloted it into spatio-temporal orbit around Earth, and, taking a deep breath, regenerated into his next incarnation, causing massive damage to the TARDIS with the energy released during the regeneration in the process. (TV: The End of Time)

Undated events

 * During their travels, the Tenth Doctor and Donna watched the courtship of the Zyglot, battled intelligent dogs in a flying house, watched the Beatles perform in 1963, prevented time from being meddled with in the 17th century and joined forces with a survey team to escape a living swamp. (COMIC: The Time of My Life)
 * The Doctor took a pop-up add from the Psychic paper, and landed on Thoros-Beta, where The TARDIS landed on an angry Mentor named Gom. (COMIC: Psychic Paper Inc Claims Department)

Alternate timelines
In a parallel timeline in which Donna Noble never met him, and wasn't there to convince him to flee after defeating the Empress of the Racnoss, the Doctor drowned when the Thames was drained into the abandoned Torchwood base. For some reason, the Doctor didn't regenerate; Private Harris speculated it had happened too fast for the process to start. His body was retrieved by UNIT soldiers and his TARDIS was salvaged from under the Thames, later being sent to a UNIT base in Leeds. (TV: Turn Left) In another alternative timeline envisioned by a continuity bomb, the Doctor let Wilfred die in the radiation chamber. He went on to embrace the title of Time Lord Victorious and became a dictator, in his own words, "He whose rule has fixed a broken cosmos". He found his end at the hands of a Raxacoricofallapatorian that shot him with a weapon that seemingly canceled the regenerative process. This timeline never saw full creation because the bomb was confused by the presence of three Time Lords trapped inside of itself. (COMIC: Four Doctors)

Personality
The Tenth Doctor was cheerful, charismatic, hyperactive and enthusiastic, often at inappropriate times, (TV: Tooth and Claw) but would become serious and demanding when the situation called for it. (TV: Army of Ghosts, Evolution of the Daleks) He regularly used his name as a threat, which only rarely worked, despite his apparent expectations. (TV: New Earth) According to his successor, he had vanity issues. (TV: The Time of the Doctor)

The Doctor's human side made him a more loving and fun character to be around, being very much a good friend to all his companions and welcomed anyone with open arms. (TV: The Lazarus Experiment) He became almost like a family man, especially with the Tyler family. (TV: The Christmas Invasion) He tended to keep a massive smile on his face and simply enjoyed his journeys through time and space. (TV: The Waters of Mars) While previous incarnations intentionally flouted social conventions, the tenth incarnation was genuinely shocked when he realised that he was being rude or uncouth. (TV: The Christmas Invasion, Tooth and Claw, Fear Her)

The Doctor had a merciful and compassionate nature, consistently extending an offer to help even his most dangerous enemies before putting a stop to their evil deeds. However, when his patience reached its limit or his enemies were duplicitous, they received no mercy or second chances. (TV: The Christmas Invasion, School Reunion, Evolution of the Daleks, The Family of Blood, The Next Doctor) He also held a forgiving philosophy, being willing to forgive even for his crimes against humanity. (TV: Last of the Time Lords)

The Doctor retained and even exceeded his predecessor's capacity for righteous anger, particularly when his friends were threatened or at risk. (TV: The Idiot's Lantern) When driven by anger or justice, he would act without hesitation to strike down those who opposed him. (TV: The Christmas Invasion, The Runaway Bride)

While he seemed to have resolved much of the survivor's guilt felt previously, the Tenth Doctor had begun to feel his age. Beneath his juvenile exterior was an old man who had seen many terrible things and felt a deep loneliness. (TV: School Reunion, The Lazarus Experiment, Partners in Crime) He felt profound regret for the deaths he'd seen, (TV: Journey's End) with the Moment referring to him as "the man who regrets". (TV: The Day of the Doctor) His keen sense of loss led him to empathise with those who had also suffered, (TV: The Idiot's Lantern) and feel driven to prevent death and destruction wherever possible, (TV: New Earth, Forest of the Dead) having a hard time accepting failure. (TV: Voyage of the Damned) Donna Noble noted the reason the Doctor required a companion was to keep him from succumbing to his darker side. (TV: The Runaway Bride)

The Tenth Doctor's main personality flaw was his ego, with him always trying to take control of situations he found himself in, (TV: Army of Ghosts, 42, Silence in the Library) and feeling it his place to punish those who committed horrific acts. (TV: The Family of Blood) He deposed Prime Minister Harriet Jones, thus negating the "Golden Age" she was destined to achieve, for committing what he saw as an act of murder. (TV: The Christmas Invasion) Occasionally, he stated himself to be at a higher authority than he actually was. (TV: New Earth, Voyage of the Damned, The Waters of Mars)

He was also something of a hypocrite, claiming he would not allow Strackman Lux's pride to cost lives, while refusing to sign Lux's contract for the same reason, (TV: Silence in the Library) and being offended when Malcolm Taylor hung up on him, despite him previously doing the same to Malcolm. (TV: Planet of the Dead)

The tenth incarnation engaged in romantic situations far more frequently than his predecessors, (TV: The Day of the Doctor) falling in love with Rose Tyler. However, he unable able to explicitly described these feelings, struggling with saying such things aloud. (TV: School Reunion, The Satan Pit, Doomsday) In the end, it was the Meta-Crisis Tenth Doctor that revealed the Doctor's feelings for her. (TV: Journey's End) Others who tried to engage him romantically included Madame de Pompadour, (TV: The Girl in the Fireplace) Martha Jones, (TV: Human Nature, Last of the Time Lords) Jack Harkness, (TV: The Sound of Drums) Astrid Peth, (TV: Voyage of the Damned) Clare Pope, (TV: Partners in Crime) River Song, (TV: Silence in the Library, Forest of the Dead) Christina de Souza, (TV: Planet of the Dead) Minnie Hooper, (TV: The End of Time) and Elizabeth I. (TV: The Day of the Doctor) Joan Redfern became romantically involved with his human identity, but viewed the Doctor himself as merely a look-a-like of him. (TV: Human Nature, The Family of Blood)

The Doctor refused to take up a weapon against an enemy, believing it unbrave to do so. (PROSE: Made of Steel) While previous incarnations had, the tenth incarnation would not, repeatedly refusing even when offered one by UNIT while attacking the Sontarans. (TV: The Poison Sky) Davros noted his refusal to take up a gun, but pointed out that he "turned those around him into weapons." (TV: Journey's End) After initially refusing several times to take up Wilfred Mott's pistol to save himself and humanity from, the Doctor changed his mind when he heard that the Time Lords were returning. (TV: The End of Time) However, during a battle with the Cybermen, the Doctor helped Major Burton handle a rocket launcher and destroyed a Cyberman with the weapon, despite hesitating due to it previously being human. (PROSE: Made of Steel) He was also tempted to execute General Cobb for the murder of Jenny, but ultimately decided against it. (TV: The Doctor's Daughter)

The Doctor always attempted to solve a situation without violence, (TV: The Christmas Invasion, New Earth, Evolution of the Daleks, The End of Time) which strained his working relationship with UNIT, with him being against their military methods. (TV: The Sontaran Stratagem, The Poison Sky, Planet of the Dead) When Clara Oswald insisted the War, Tenth and Eleventh Doctors find a different way to end the Time War, this incarnation embraced the chance to do so when a plan was formed and worked with all of his other twelve incarnations to save his planet and people. He was upset when he realised he wouldn't be able to remember what he did, but was still happy with the outcome. (TV: The Day of the Doctor)

Much like his fourth incarnation, the Tenth Doctor had a great respect for humanity, as well as a great desire to protect it, often noting their importance, (TV: The Christmas Invasion) describing human beings as both brilliant and stupid in the same sentence while arguing the necessity of emotions with John Lumic. (TV: The Age of Steel) He even hugged Zachary Cross Flane, the captain of the Walker Expedition, due to the human crew daring to explore a planet orbiting a black hole merely "because it was there". (TV: The Impossible Planet) When Wilf said that humanity must look like insects to a Time Lord, the Doctor responded that he thought they looked like giants. He particularly had a great respect for Wilf, thinking of him as a kindred spirit, as he was also aged and experienced, yet energetic and unwilling to commit violence against others. The Doctor also stated that he felt it an honour to know Wilf, and claimed he would have been proud if he was his father. (TV: The End of Time)

After being forced to wipe Donna Noble's memories of her travels with him, the Doctor was driven into a deep state of depression, (TV: Journey's End) and exiled himself away from the idea of picking up any more companions, (TV: The Next Doctor) even refusing Lady Christina de Souza's request to travel with him, (TV: Planet of the Dead) though he made exceptions with Gisella, (PROSE: The Depths of Despair) Majenta Pryce, (COMIC: Thinktwice) Gabby Gonzalez, (COMIC: The Arts in Space), Emily Winter, Matthew Finnegan, (COMIC: Fugitive) Heather McCrimmon, (COMIC: The Chromosome Connection) and Wolfgang Ryter. (COMIC: Flight of the Giurgeax)

After he was given a prophecy of his demise by a human psychic, the Doctor spiraled further into an emotional breakdown that caused him to snap and try to alter a Fixed point in Time by saving Adelaide Brooke, Yuri Kerenski and Mia Bennett from the destruction of Bowie Base One. Upon his success, he declared himself as the "Time Lord Victorious" and believed that, as the last Time Lord, he had the right to control the Laws of Time. Following Brooke's suicide, the Doctor realised he had gone too far and entered another state of depression upon knowing his regeneration was fast approaching. (TV: The Waters of Mars) By the time he had decided to go to the Ood Sphere, the Doctor had mostly recovered from his ordeal on Mars, but still showed signs of a colder demeanor, such as questioning Wilf's importance during their conversation about their reunion. (TV: The End of Time)

The Doctor held a rather low opinion of his previous incarnation, considering him to be violent due to being "born in battle". (TV: Journey's End)

Tim Latimer described the Tenth Doctor as "like fire and ice and rage, [that he was] like the night and the storm in the heart of the sun, [as well as being] ancient and forever, [burning] at the centre of time, and [could] see the turn of the universe." Despite his description, Latimer considered the Doctor to be "wonderful," (TV: The Family of Blood) a sentiment that Wilfred Mott also expressed. (TV: The End of Time)

Having experienced a similar processes as John Smith, (TV: The Family of Blood) the Doctor became fearful of his inevitable regeneration, going so far as to prevent the process by channelling the excess energy of his regeneration into his severed hand after being shot by a Dalek. (TV: Journey's End)

When Carmen prophesied his "song ending", the Doctor reacted with stunned silence, (TV: Planet of the Dead) and later became emotionally distressed when Ood Sigma heralded his demise. (TV: The Waters of Mars) When he realised he would have to sacrifice his life to save Wilfred Mott from the radiation of the Immortality Gate after thwarting Rassilon's Ultimate Sanction, the Doctor at first had a tantrum about how his "reward" was "not fair" and was tempted to let Wilf die when he requested it, but ultimately decided to fulfill Carmen's prophecy and save Wilf. (TV: The End of Time)

While he put on a brave face for Rose, Jack and Donna during his aborted regeneration, (TV: The Stolen Earth) when his time finally came, the Doctor instead stated his reluctance to "go", and regenerated with tears in his eyes, afraid and alone. (TV: The End of Time)

Habits and quirks
The Tenth Doctor was an aficionado of twentieth century culture and made frequent references to movies, shows, books and songs from that era, (TV: The Christmas Invasion, The Idiot's Lantern, Army of Ghosts, The Shakespeare Code) though did not understand certain remarks, such as being called a "science geek". (TV: The Lazarus Experiment) He was also fond of rock-and-roll, attempting to take Rose to see concerts by both Ian Dury and Elvis Presley. (TV: Tooth and Claw, The Idiot's Lantern)

The Doctor often remarked that exotic technology or life was "beautiful" or "brilliant" and was genuinely enthralled by such discoveries, sometimes to the extent that he placed himself, his companions and bystanders in danger. (TV: The Christmas Invasion, Tooth and Claw, Midnight) Like his seventh incarnation, he would insist he was "always all right", even when all evidence pointed to the contrary. (TV: The Girl in the Fireplace, Forest of the Dead)

When he was faced with an occurrence that dumbfounded him, the Doctor would repeatedly say, "What?", looking increasingly astonished with each repetition. (TV: Doomsday, The Shakespeare Code, Last of the Time Lords, Time Crash) When he discovered something that disagreed with his knowledge, he would usually utter, "it can't be", (TV: School Reunion, The Impossible Planet, Utopia, The Sound of Drums, The Stolen Earth) and would frequently describe something that dumbfounded him as "impossible". (TV: New Earth, Rise of the Cybermen, The Impossible Planet, Army of Ghosts, The Runaway Bride, The Stolen Earth)

While attempting to explain something, he would often interrupt himself with a "Well" and further elaborate what it was he was talking about. (TV: The Christmas Invasion, The Girl in the Fireplace, The Satan Pit, Army of Ghosts, Smith and Jones, The Shakespeare Code, The Lazarus Experiment, Blink, Utopia, Time Crash, Voyage of the Damned, Partners in Crime, The Fires of Pompeii, The Unicorn and the Wasp) Another favoured exclamation of his was, "Oh, yes!", which he would say in moments of gleeful realisation, (TV: Tooth and Claw, The Satan Pit, The Sound of Drums, Voyage of the Damned, Planet of the Ood) when angered or disturbed greatly, (TV: Army of Ghosts, Evolution of the Daleks, The End of Time) or simply as a response to something. (TV: The Age of Steel, The Shakespeare Code, Partners in Crime, The Doctor's Daughter)

The Doctor was fond of the French word, "Allons-y!", (TV: Army of Ghosts, Evolution of the Daleks, 42, Voyage of the Damned, The Fires of Pompeii, Midnight, The Next Doctor, Planet of the Dead, The Wedding of Sarah Jane Smith, The Day of the Doctor) describing it to Addams as a "word of consolation to the soul in times of need". (TV: The End of Time) An apologetic incarnation, the Tenth Doctor also made use of the phrase, "I'm sorry, I'm so sorry", (TV: New Earth, The Impossible Planet, Last of the Time Lords, The Poison Sky, The Next Doctor) especially when someone was about to die and he could not save them. (TV: The Age of Steel, Army of Ghosts, Silence in the Library) Another favoured phrase of his was "Molto bene". (TV: The Runaway Bride, The Family of Blood, Planet of the Ood, Midnight)

Until they left his life, the Doctor continued his previous incarnation's habit of mildly mocking both Mickey Smith and Jackie Tyler, though generally in a more playful fashion. (TV: The Christmas Invasion, School Reunion, Rise of the Cybermen, Army of Ghosts) He also enjoyed teasing his companions, usually in a less playful manner than his previous selves, (TV: The Runaway Bride, The Lazarus Experiment, The Wedding of Sarah Jane Smith) and was not above mocking them behind their back. (TV: Smith and Jones) The Doctor also prodded at Jack after they reunited, resuming his habit of telling Jack to "stop it" whenever he said hello to someone, which was his tell-tale way of flirting with them. (TV: Utopia)

The tenth incarnation was a foodie, having a fondness for many types of food and drink, with his companions being dumbfounded and bemused by his eating habits. (PROSE: The Nightmare of Black Island; TV: The Lazarus Experiment) Like his predecessor, he had a fondness for bananas, (TV: The Girl in the Fireplace) and expressed a fondness for tea. (TV: The Christmas Invasion) He also liked edible ball bearings, stating that they were a "masterpiece". (TV: Fear Her) The Doctor often talked about favourite foods and recipes, and wasn't afraid to try something new, such as seaweed truffles. (PROSE: Martha in the Mirror)

The Doctor had a stated fondness for "little shops", the gift stores usually found in hospitals and other public places, though he retained his eighth incarnation's dislike for hospitals. (TV: New Earth, Smith and Jones, Silence in the Library)

The Doctor relied heavily upon his sonic screwdriver, pushing it to limits not seen in previous incarnations, (TV: The Runaway Bride, Smith and Jones, Partners in Crime) and even chiding the Fifth Doctor for going "hands free". (TV: Time Crash)

He also continued to heavily use the psychic paper, (TV: Tooth and Claw, The Idiot's Lantern, Fear Her, The Shakespeare Code, Evolution of the Daleks, The Infinite Quest, Partners in Crime, Planet of the Ood, The Unicorn and the Wasp, Planet of the Dead) and appeared to have the ability to carry a large and diverse number of objects in his pockets, telling Donna Noble that they were "bigger on the inside". (TV: The Runaway Bride) The Doctor also revived the occasional use of a stethoscope in mostly non-medical situations, such as the diagnosis of electronic or mechanical faults or to eavesdrop on others. (TV: Rise of the Cybermen, The Idiot's Lantern, Partners in Crime, The Stolen Earth) He used a hammer many times during this incarnation, often to help pilot the TARDIS. (TV: The Runaway Bride)

The Tenth Doctor often did math calculations in his head very quickly. This included making an estimate, waiting for those around him to respond, then giving a very exact answer. (TV: Voyage of the Damned)

Skills and abilities
Although he disliked violence, the Doctor was skilled with a sword, (TV: The Christmas Invasion, The Next Doctor) and also an extremely good shot with a gun, being able to shoot a White-Point Star from a distance, (TV: The End of Time) as well as throw and catch objects with pinpoint accuracy. (TV: The Christmas Invasion, The Family of Blood) He was also a exceptionally skilled detective, picking up on details on what Eddie Connolly did for a living after getting a brief glimpse inside his house, (TV: The Idiot's Lantern) and figuring out that Martha had been cloned by studying the behavior of her clone. (TV: The Poison Sky)

The Doctor was also incredibly resilient and showed an immense resistance to physical pain, being unfazed when the Sycorax leader sliced off his hand, (TV: The Christmas Invasion) and enduring the burning pain of having a living star possessing him, in addition to surviving attempts to freeze the star out of him. (TV: 42) He also took a powerful blast of electricity from, was able to get to his feet with only some difficulty after jumping out of a ship and falling through a skylight, and was able to absorb 500 thousand rads of nuclear energy and survive as well, although it was the final straw for his body and triggered his regeneration, but he refused to allow the pain of the regeneration to overwhelm him until he was back in the TARDIS after visiting his old companions. (TV: The End of Time)

Given his height and build, it was not surprising that the Doctor was extremely nimble and quick on his feet, keeping ahead of others with ease. (TV: Tooth and Claw, Planet of the Ood, The Doctor's Daughter) Despite his nimble stature, the Doctor was very strong, freeing Morvin Van Hoff from the grip of a damaged Heavenly Host, and matching the strength of a Cyberman, as well as overpowering it, with a sword. (TV: Voyage of the Damned, The Next Doctor)

Like his previous incarnations, the Tenth Doctor was exceptionally intelligent, being able to figure out solutions to problems even when they were created by an equally intelligent opponent. (TV: School Reunion, The Sound of Drums) He also possessed a heightened sense of smell, which he used to tell which time period he was in by smelling the air, (TV: The Unicorn and the Wasp) and track down the Master. (TV: The End of Time) He also demonstrated the ability to determine the properties of an object by taste. (TV: The Christmas Invasion, Tooth and Claw)

The tenth incarnation was skilled at mechanics, having built K9 Mark IV to replace the Mark III after he was destroyed, (TV: School Reunion) as well as being able to construct a variant of other gadgets. (TV: Blink, The Day of the Doctor) He was also able to lock the coordinates of the TARDIS with his sonic screwdriver so that it could only travel to two places in time and space. (TV: Utopia, The Sound of Drums)

The Doctor was a skilled pilot, on a few occasions able to take control and navigate a spacecraft through and out of danger. (TV: Voyage of the Damned, The End of Time) He also followed the trend of his immediate predecessor in displaying increasing skill for using the TARDIS, landing with great accuracy in intended time periods, (TV: The Lazarus Experiment) and even using it in the form of a standard spaceship rather than simply dematerialising it on several occasions. (TV: The Runaway Bride, Partners in Crime) When told by River Song that he would one day be able to command the TARDIS door to open with a snap of his fingers, he found that he did possess such abilities, after initially believing it to be nonsense. (TV: Forest of the Dead)

The Tenth Doctor was also a skilled telepath, (TV: The Girl in the Fireplace, Fear Her, The End of Time) being able to wipe Donna Noble's memories, (TV: Journey's End) and to hide his true name from those who could read minds. (TV: The Shakespeare Code) During the The Year That Never Was, the Doctor also managed to tune himself into the Archangel Network in his plan to defeat. (TV: Last of the Time Lords)

The Doctor was able to channel radiation through a body part into his own clothing, although the radiated body part was described by him as being "itchy." (TV: Smith and Jones) However, he could only do this with a small amount of radiation and the radiation he absorbed to save Wilfred Mott was too much for him and he was forced to regenerate. (TV: The End of Time) If poisoned, he could also "stimulate the inhibited enzymes [of cyanide] into reversal" by ingesting ginger beer, a form of protein, salt, and receiving a shock. (TV: The Unicorn and the Wasp)

The Doctor also showed an impressive amount of control over his regenerative abilities, more so than his previous incarnations. He was able to heal himself after being shot by a Dalek and then stop himself from changing his form by channelling the regeneration energy into his severed hand. (TV: Journey's End) He was also able to resist regenerating long enough to visit his old friends, though this resulted in his regeneration becoming so violent that the TARDIS was set ablaze in the process. (TV: The End of Time)

Appearance
The Tenth Doctor was a handsome man with a tall, slim frame, finely boned hands and face, thick brown hair, pale skin scattered with freckles, and large, dark brown eyes. He had a mole between his shoulder blades. (TV: The Parting of the Ways, Children in Need Special) He went clean-shaven. (TV: Time Crash)

The Doctor was considered attractive by people he encountered on his travels, and seemingly thought this of himself as well - his next incarnation would characterise him as having vanity issues. (TV: The Time of the Doctor)

While he was possessed by Lady Cassandra at New New York Hospital, Cassandra stated that he was "slim and a little bit foxy." (TV: New Earth) Donna Noble described him as "too skinny for words", (TV: The Sontaran Stratagem) while the Eleventh Doctor described his skinniness as a "special effect". (TV: The Day of the Doctor)

Grooming and hair
The Doctor was happy to have sideburns and to have more hair than his previous incarnation. (TV: Children in Need Special) Though he initially seemed disappointed at not being ginger, he came to take great pride in his dark brown hair, wearing it in various ways throughout his adventures. He would wear it un-styled, (TV: The Christmas Invasion) in a quiff, (TV: The Idiot's Lantern) or flattened forwards. (TV: The Runaway Bride) At some point, he began to experiment with back-combing his hair. (TV: Fear Her)

Wilfred Mott described the Doctor's hair to the Silver Cloak as being a "modern style", and "all sticky-uppy". (TV: The End of Time)

Clothing
For the early moments of his life, the Doctor continued to wear the clothes his previous incarnation had on at the time of his regeneration. After arriving in London and collapsing, he was placed in a set of pyjamas and a dressing gown by Jackie Tyler, which he kept until he chose a new outfit from the TARDIS wardrobe. (TV: Children in Need Special, The Christmas Invasion)

The Doctor had two main suits, a dark brown suit with blue pinstripes, (TV: The Christmas Invasion) and a blue suit with red pinstripes. (TV: Smith and Jones) For certain formal occasions, he would also don a Bow tie and tuxedo. (TV: Rise of the Cybermen, The Lazarus Experiment, Voyage of the Damned)

Under his suits he usually wore a shirt and tie, or wore an open-necked shirt with a t-shirt underneath. (TV: Fear Her) He had a red-hued t-shirt, a brown t-shirt or a purple t-shirt.

Both brown and blue suits were often accompanied by a light brown Duster-type overcoat, (TV: The Christmas Invasion) which the Doctor claimed had been given to him by Janis Joplin. (TV: Gridlock) He usually took it off while doing fiddly tasks, piloting the TARDIS, or when about to do something of which the coat would get in the way. (TV: Gridlock)

His footwear choices were trainers, Converse All Stars to be specific. (TV: Time Crash) He varied the colours from cream white (TV: The Family of Blood), red, (TV: The Sontaran Stratagem) and black. (TV: The Lazarus Experiment) Despite his protests, both his war and eleventh incarnations stated the trainers he wore were sand-shoes. (TV: The Day of the Doctor)

Another part of the Doctor's attire were a pair of dark tortoise-shell rectangular frame glasses, which he called "brainy specs". Although he wore them on numerous occasions, he later pointed out to his fifth incarnation that he didn't need them and simply used them because they made him look clever. (TV: Time Crash) At one time, the Doctor used his sonic screwdriver to darken the lenses to effectively turn them into sunglasses. (TV: Planet of the Dead)

Lifespan
The Ninth Doctor stated that he was 900 years old by the time of his travels with Rose. (TV: Aliens of London)

The Tenth Doctor himself stated his age was 903 immediately after Martha Jones stopped travelling with him, (TV: Voyage of the Damned) and later stated he was 904 years old to a rabbit in 1562 England. (TV: The Day of the Doctor)

Given his stated age of 906 just prior to his regeneration, (TV: The End of Time), and his next incarnation giving his age as 907 a few days afterwards, (TV: Flesh and Stone) this incarnation lived for 7-to-8 years. However, some accounts suggested his stated tally may not have been correct. (TV: The Infinite Quest, PROSE: The Haldenmor Fugue)

Costuming
David Tennant described his costume "geek chic". According to an interview on Parkinson, Tennant and Russell T Davies got the idea for the tenth incarnation's costume from an outfit Jamie Oliver had worn on Parkinson just after Tennant had taken the role of the Doctor. According to Doctor Who Confidential, one of the first things Tennant said after deciding to take the part was "I want a coat down to here," pointing to his ankle.

According to costume designer Louise Page, there were only four sets of the brown suit in existence, as they were pieced together from many copies of a pin-striped pair of trousers that Tennant picked out during the initial costuming process. His overcoat was made from sofa covering and there was one version that had five inches from the bottom cut off then sewn back on, as Davies and Phil Collinson had different ideas about how long it should be.

After leaving the series, David Tennant kept his costume for possible future use, stating that he would gladly return for a multi-Doctor special should he ever be asked to participate in one. (DCOM: The End of Time) Eventually, he did return in The Day of the Doctor.

The Brilliant Book
According to the non-narrative source The Brilliant Book 2011, the Doctor was searching for Sontaran grenades in 1895. During his search, he came across his old friend Winston Churchill.

Other matters

 * According to a scene deleted from Human Nature (available as an Easter egg on the DVD release), the Doctor hated pears and (like his sixth incarnation) carrots.
 * In the Japanese dubbing of the show, the Tenth Doctor is played by Toshihiko Seki.
