Ninth Doctor

Emerging from the Last Great Time War as whom he believed was its sole survivor, the Ninth Doctor spent much of his life grieving over the immense suffering he had witnessed. He struggled with the idea that he was the last of the Time Lords, having left the conflict with the excruciating knowledge of his hand in its apparent grisly conclusion.

Now cut off from the Time Lord race, the Doctor found himself alone and bereaved. Emotionally haunted by the war, he entered a darker period of his life spattered by resentment, where he tended to brood and act rudely to those who rubbed him the wrong way. Despite this, he remained jovial and friendly towards anyone he took a liking to, slowly reasserting himself as the Doctor while letting go of his lingering wartime persona to become worthy of being called "The Doctor" again.

Rose Tyler was his most constant companion, although, during the Slitheen family's attempt to destroy the Earth for profit, he also gained a temporary ally in Harriet Jones. The crisis also began an on-going love/hate relationship between the Doctor and Rose's mother, Jackie, as well as with Rose's ex-boyfriend, Mickey Smith.

He also had a short spell of adventures with Adam Mitchell, an employee of Henry van Statten, at Rose's request, but evicted him for almost dramatically altering human history. Adam later returned to exact revenge on the Doctor for booting him from the TARDIS, but redeemed himself as a companion by sacrificing himself to defeat.

After resuming his adventures with just Rose, the pair were accidentally scammed by the ex-Time Agent Captain Jack Harkness. After helping him resolve the Empty Child plague, they welcomed him on board the TARDIS in their travels. There they began a quest to recover Jack's memories that were wiped by the Time Agency, running into a future Mickey Smith, sharing an adventure with the Brigadier, and ending up with a stowaway companion in Tara Mishra.

The Ninth Doctor met his end upon discovering that Daleks that had survived the Time War had been rebuilding their ranks by manipulating the Fourth Great and Bountiful Human Empire to their advantage. Rose briefly absorbed the power of the time vortex and became the god-like Bad Wolf entity. Once Rose destroyed the Daleks, the Doctor absorbed the energy out of her, forcing him to regenerate to survive.

A day to come
When Ace was sent into the Seventh Doctor's mind, she discovered a room with thirteen cubicles, seven of them empty, while the other six contained shadowy white figures, representing the Doctor's future incarnations. (PROSE: Timewyrm: Revelation)

When the Eighth Doctor looked into the Tomorrow Windows, he saw this Doctor as what he might look like in his future. (PROSE: The Tomorrow Windows)

Post-regeneration
At the end of the Last Great Time War, the War Doctor's regenerative processes initiated automatically after he had joined with his twelve other incarnations to put Gallifrey into a stasis cube. As his body was frail and had visibly aged into that of an old man, the Doctor believed his death was due to him "wearing a bit thin."

However, due to the timelines being "out of synch" from the presence of his future selves, (TV: The Day of the Doctor) the newly-regenerated Doctor simply thought that he had been "born in battle," (TV: Journey's End) and believed that he had caused the destruction of Gallifrey, and the death of billions of innocent Time Lords. (TV: The End of the World, Dalek) As a result of not knowing the truth, the Doctor began repressing the very memory of ever being the War Doctor, whom he believed had broken the vow of being the Doctor. (TV: The Day of the Doctor)

Early days
Filled with regret, (COMIC: The Promise) and deciding he "didn't need companions or friends" after the Time War, the Doctor travelled alone. (PROSE: The Eyeless) He appeared in Dallas during the assassination of U.S. President John F. Kennedy on 22 November 1963, in Southampton just before the voyage of the RMS Titanic in April 1912, and in Indonesia on the day of Krakatoa's eruption in August 1883. (TV: Rose)

Searching for peace, the Doctor went to Galen, where he found that something was causing the people on the planet to want to kill. Teaming up with news reporter Adriana Jarsdel, he found that it was being caused by a rift in interstitial space. During the Time War, a race called the Compassionate were trapped in the rift by Rassilon and the Time Lords. Taking apart his sonic screwdriver, he sent it into the rift, managing to seal it up and leave the Compassionate trapped on the other side, unable to influence the universe any more. (AUDIO: The Bleeding Heart)

The Doctor visited his old friend Plex to deliver the news that his home planet had been destroyed in a freak singularity. The Doctor discovered that Plex had created hundreds of clones of himself to populate the empty planet where he resided. In light of Plex having recently become the last of his species, the Doctor realised that Plex's plan made sense and gave him a modified Chameleon Arch to "copy and paste" his memories into the clones. (COMIC: The Promise)

The Doctor followed traces of a Gallifreyan stone to London, 1939, where he discovered that RATS were also after the stone when one of them attacked Winston Churchill's secretary, Hetty Warner. The Doctor was reluctant to take part in events, allowing Churchill and his colleagues to investigate the incident. However, when Churchill was captured and refused to surrender, the Doctor had no choice but to intervene, stopping the RATS and saving the Prime Minister. (AUDIO: The Oncoming Storm)

The Doctor met Madame Vastra when she was awoken by construction being done to the London Underground. After slaughtering five innocent workers for the accidental deaths of her sisters, the Doctor managed to talk her down and help her integrate into Victorian society. (TV: A Good Man Goes to War, COMIC: The Lost Dimension) Though he knew the truth, he allowed Vastra to believe she was the last of her kind and spoke to her of the loss of his own people, (COMIC: The Lost Dimension) confiding in her many secrets of the Time Lords. (TV: A Good Man Goes to War)

Meeting Rose Tyler
While still "not quite calibrated" to his latest body, the Doctor was alerted by the TARDIS to a temporal problem in 2005 London involving the Nestene Consciousness. (PROSE: The Beast of Babylon) While tracking down the Consciousness, the Doctor found a chief electrical officer murdered in the London shop, Henrik's. Continuing his investigation, he encountered a group of Autons who had surrounded Rose Tyler, a young employee of the shop. Pulling her away from them, he warned her that he was going to blow up the building, and told her to run. By the time Rose had made it to the streets, the Doctor had blown up the store.

The next day, the Doctor tracked down the signal from the amputated Auton arm he had passed to Rose to the Powell Estate, where she lived. After saving her when it attacked, the Doctor took it to his TARDIS, telling her to forget him.

The Doctor ran into Rose again when he saved her from an Auton duplicate of her boyfriend Mickey Smith, pulling off the Auton's head. Escaping from the rampage of Auton Mickey's headless body, the Doctor took Rose to the TARDIS, where he used the head to trace the control signal of the Nestene Consciousness. Discovering the Consciousness and the original Mickey in a base beneath the London Eye, the Doctor asked the Consciousness to leave Earth, and find another planet to feed off. It refused, and ordered two Autons to take the Doctor prisoner and confiscate the anti-plastic he was holding.

Unable to escape the base without access to the TARDIS, Rose kicked the Autons and the anti-plastic into the vat containing the Nestene Consciousness, saving the Doctor's life and destroying the Consciousness. Taking Rose and Mickey in the TARDIS to safety, the Doctor asked Rose to travel with him, but made it clear Mickey wasn't invited. After she turned him down, he departed. (TV: Rose)

Solo adventures
Still on his own, the Doctor picked up a distress call from the Godspeed and joined forces with the ship's captain, Locklear, to stop energy-consuming space barnacles from killing the crew. He summoned them to his TARDIS by flashing its rooftop light, and, with the barnacles surrounding the exterior, transported them to a nearby asteroid belt so they could feed off the sun. (PROSE: The Hungry Night)

Posing as a woodcutter, the Doctor saved a little girl named Rose and her grandmother from a Zygon. He explained what happened to Rose and her grandmother over tea, before excusing himself to the TARDIS. (PROSE: Little Rose Riding Hood)

The Doctor teamed up with all of his other incarnations to save Gallifrey from destruction at the end of the Last Great Time War, but lost all memory of the event due to the timelines not being synchronised. (TV: The Day of the Doctor)

In 21st century Istanbul, the Doctor fought a Sontaran in a sword fight. Sally Sparrow saved him from a second one and gave him her Christmas homework from 2005, and told him to keep it on him at all times. (PROSE: What I Did on My Christmas Holidays by Sally Sparrow)

The Doctor delivered letters from his fifth incarnation to Clarrie and his former companions Peri Brown and Erimem at the Kingmaker inn in 1483, (AUDIO: The Kingmaker) tended to Honoré Lechasseur's injuries after a bunker exploded in 1951, (PROSE: The Albino's Dancer) and took Alexander Pope and Theobald to see William Shakespeare's Cardenio. (PROSE: Double Falsehood)

The Doctor was left stranded in Devon in 1985 when the TARDIS jumped forwards in time to 2005. Reading Sally's homework, the Doctor found where to leave messages for Sally at the nearby house and garden so her twelve-year-old self could read them in the future. One of these messages included telling her to find a video tape at the back of the living room top shelf. He recorded a message for the tape, and spoke in a conversation with Sally from 2005, explaining where the TARDIS was and that the Christmas essay had the conversation transcript.

The TARDIS arrived and Sally exited, telling the past Sally to use the TARDIS' reset button next to the phone to return the TARDIS to the Doctor. The Doctor reminded the past Sally to complete her homework before she went to the TARDIS and placed the message on the shelf so she could read it in 2005. (PROSE: What I Did on My Christmas Holidays by Sally Sparrow)

Landing in post-Civil War Nebraska, the Doctor happened upon a circus and started exploring, but his suspicions were aroused when nobody was talking. Meeting a woman named Mona, who posed as a bearded woman for the circus' freak show, he learned from her that there were rumours of a mysterious figure that followed the circus and led to people's disappearances, that nobody was willing to talk about. The Doctor gained her trust by showing her the psychic paper which identified him as a maverick with the local sheriff's department, so she brought him to meet Jacob, who further explained the story and admitted that he had seen this Pierrot, and was quite shaken by it.

The Doctor hung around the circus all day and night, trying to gather more information, when he was found by Mona, who'd decided to help him solve what was going on. They followed mismatched footprints to the Big Top tent, where Mona was kidnapped by the Pierrot. The Doctor tracked the pair down to an old trailer full of surgical equipment, and identified the Pierrot as a Cyberman that fell through a space-time breach and, stranded from technology, began replacing its decaying flesh rather than its corroding machinery, leaving it more human as a result. The Doctor was horrified to learn that the Cyberman had developed feelings for Mona, and stole Jacob's face in order to appeal to her.

The Doctor used his sonic screwdriver to disable the Cyberman's emotional inhibitor, causing it to break down sobbing in agony, allowing him to rescue Mona. As they left the whimpering Cyberman, the Doctor apologised for what he had done to it. After offering to stay with a shocked Mona, he returned to the trailer to find the Cyberman, but discovered that it had left without a trace. (PROSE: The Patchwork Pierrot)

Tracking the Starman
After he was alerted to the presence of a Starman by the TARDIS, the Doctor stole an orb made from a collapsed star from the Exalted Holgoroth of All Tagkhanastria by pretending to be an emissary from the Crab Nebula. He then chased the Starman to Karkinos, where, after he failed to persuade a picnicking family of Karkinians to flee, he used the orb to knock the Starman into the twenty-sixth dimension. However, he lost the orb in the confusion, and later discovered that using the orb had caused ripples spreading out the time stream that created a far worse Starman, that was also linked to the Doctor's time stream.

Tracking down the orb to the daughter of the Karkinian family, Ali, the Doctor let her tag along with him to 2000 BC Babylon to defeat the Starman. While Ali remained in the TARDIS, the Doctor was met by the High Priest Zabaia, but things turned hostile when a curious guard went into the TARDIS and was slayed by Ali. Now feared to be a sorcerer and a spy, the Doctor was taken to be executed before King Hammurabi, but was saved by Ali's killing of Gurgurum and the arrival of the Starman. After Ali handed him the orb, the Doctor rode her as she scaled up the Starman, and threw the orb into the beast's mouth, causing it to explode.

Landing near a palm tree, the Doctor was approached by Hammurabi, who apologised for doubting him, as well as Zabaia, who desired to add the Doctor to Babylonian history. However, Ali, believing Zabaia was going to try and hurt the Doctor again, murdered one of the High Priest's judges, swatted Zabaia himself away and advanced on Hammurabi, until the Doctor talked her down. After he dropped her off home, Ali persuaded the Doctor to return to Rose Tyler and get her to join him. (PROSE: The Beast of Babylon)

The Doctor rematerialised by Rose and Mickey, a few seconds later from their perspective, and told Rose that the TARDIS was capable of travelling in time, before slipping his head back in. (TV: Rose) Watching from behind the TARDIS doors, the Doctor saw Rose give Mickey a farewell kiss, before running to join the Doctor in the TARDIS, having accepted his offer of companionship. (TV: Rose; PROSE: The Beast of Babylon)

Adventures with Rose
For Rose's first trip, the Doctor took her to Platform One in the year 5000000000 to observe the Earth's destruction by the sun. While there, the Doctor befriended Jabe, a representative of the Forest of Cheem, after she learned that he was the only surviving Time Lord. Jabe consoled him and felt sorry for his loss, causing the Doctor to shed a tear out of thankfulness at her sympathy.

The Doctor saved the other sightseers from Lady Cassandra O'Brien.Δ17's plot to burn them alive for insurance money, at the cost of Jabe's life. He let Cassandra's frame of skin dry out and explode as punishment when he foiled her plan, ignoring her cries for help, (TV: The End of the World) though Cassandra's brain survived. (TV: New Earth) He told Rose of the Last Great Time War, and how he was the last of the Time Lords. (TV: The End of the World)

At Christmas in 1869 Cardiff, the Doctor and Rose found a deceased woman possessed by a Gelth, a creature turned to gas by the Time War. When Rose was kidnapped by Sneed and Company funeral parlour, the Doctor worked with Charles Dickens, whom he admired greatly, to find her, following Gabriel Sneed and Gwyneth to where other "zombies" had also been animated by the Gelth.

In Sneed's morgue, the Doctor had Gwyneth try and pull the Gelth through the Rift using her psychic connection to it. The Gelth, numbering in the billions rather than just a few, wished to wipe out humanity and take over their bodies, starting with dead bodies in Sneed and Company. The Doctor, Rose and Dickens escaped from the Gelth by filling the room with gas, sucking out the Gelth from the cadavers. Gwyneth, who had already died from contacting the Gelth, blew the house up with a match, trapping them and saving the world. Before going off in the TARDIS, the Doctor said goodbye to Dickens, telling him that his work would be remembered forever, which made Dickens a happier person. (TV: The Unquiet Dead)

The Doctor discovered an alien spaceship was trapped between real space and the time vortex, and investigating further led him and Rose to the house of Lord Farthingale in 1920. There, the Doctor overheard a detective, Dr Merrivale Carr, had identified the murderer of two people in the house as society hostess, Glenda Neil. The Doctor and Rose entered the room, explaining to the house guests that "invisible aliens" were the real cause of death. A haze appeared in the house and another guest, Bart Faversham, was suddenly thrown into the fireplace. After the guests reached safety, Rose explained that the trapped spaceship's engines was releasing an energy field that had been killing people in an attempt to move. The Doctor signalled the spaceship with the standard galactic code of the 455th century. As they were teleported on board, the Doctor and Rose discovered the ship's crew had died in the crash and the ship's computer had been moving on its own through an emergency program. The Doctor repaired the ship and he and Rose returned to the TARDIS on Earth. (PROSE: Doctor vs Doctor)

The Doctor tried to take Rose home, but arrived a year late. To his surprise, a spaceship crashed into the Thames and alerted the world to the presence of aliens. Leaving Rose to her "domestics", the Doctor went to Albion Hospital to take a look at the spaceship pilot. After UNIT officers shot the awakened Space Pig, the Doctor and Toshiko Sato discovered the pig had been sent up to space from Earth in the spaceship by other aliens and that the crash had been set up to put the world on red alert.

After returning to the Powell estate, the Doctor planned to go undercover to unmask the aliens within the government, but Rose's mother, Jackie, alerted UNIT to the Doctor's involvement and they escorted him and Rose to 10 Downing Street to help deal with the state of emergency. When the Doctor came to discuss the crisis, Rose was left in the care of MP Harriet Jones and the assembled alien experts in the room were electrocuted by the Slitheens. (TV: Aliens of London)

Being a Time Lord, the Doctor held off the electrocution and transferred it to one of the Slitheen whilst all the other experts died. The Slitheen framed the Doctor for their murders and ordered the troops to kill him. Escaping in the lift, the Doctor saved Rose and Harriet from Blon Fel-Fotch Passameer-Day Slitheen. Harriet led the Doctor and Rose to the Cabinet Room, and the Doctor shut them behind a steel barrier, trapping the trio inside but saving them from the Slitheen. To stop the Slitheen instigating a war, The Doctor contacted Mickey, and had him launch the Harpoon missile, UGM-84A, at Downing Street from the HMS Taurean. Rose found a small, sturdy cupboard inside the Cabinet Room, and, while the Slitheen were destroyed by the missile, the Doctor, Rose and Harriet hid in the room whilst 10 Downing Street was ripped apart and reduced to a pile of rubble.

After instigating Harriet's reign as Prime Minister, the Doctor invited Mickey to join him and Rose on their travels, but Mickey declined, unable to handle the dangerous life led by the Doctor. (TV: World War Three)

The Doctor and Rose travelled to London in 1966 to the site of Rose's estate before it was built. They discovered someone had been changing history, and a housing development called Brandon Mews had been built on the estate's future, even though there should have been nothing there except fields. The Doctor went to a pub to check The Daily Mirror for any other alterations to history, and discovered the football score in the World Cup had England scoring an extra goal against West Germany.

While the Doctor learnt from Charlotte Cobb that her husband Peter Cobb had mysteriously died after being followed by Lend-a-Hand girls, Rose went to Lend-a-Hand House and found that humans were also being converted into Lend-a-Hand girls. Travelling to Lend-a-Hand House, the Doctor discovered the Kustollon Igrix had travelled back in time, and planned to use Lend-a-Hand girls, initially made up of female humans, but later including biotechnology grown from Kustollon genestuff, to alter history so that humanity would be given whatever they desire and never venture out into space, and consequently never win a battle between Earth and Kustollia in 3046. To do this, Igrix killed scientists who would create things "that would make people unhappy". Igrix' first major step was to destroy the Moon in 1966, preventing any staging post from which to break out into space. With the help of Peter's work on DNA resequencing, the Doctor created a virus containing genetic instructions from Rose in the form of perfume, which Rose threw at the Lend-a-Hand girls, making them humans with human instructions.

The Doctor and Rose climbed to the top of the Post Office Tower to stop Igrix using his spaceship to fire at the Moon. The Doctor did this by spraying the human virus at his biotech ship. The ship refused to take orders from Igrix, and flew into space to explore and spend some "quality time" with Igrix. Setting history back on course, the Doctor used his sonic screwdriver to destroy the housing development, and make them start over and build Rose's future home. The Doctor also said he ought to fix the extra goal "one day". (COMIC: The Love Invasion)

The Doctor and Rose next journeyed to London in 1924 to visit the British Empire Exhibition, (PROSE: The Clockwise Man) and then to Justicia in 2501, where they encountered the Blathereen, cousins of the Slitheen family, who were plotting to use the planet's sun to reduce other worlds to cinders to use as fuel. However, the Doctor managed to stop them with the remnants of the Slitheen family, whom he was unable to stop from stealing their rival's technology. (PROSE: The Monsters Inside) Soon after, the Doctor was asked to be a representative for an alien planet, but discovered the planet's "spokesperson", Akimus Makassar, was planning to take over the other visiting representatives' minds. The Doctor placed himself and Rose in a dreamscape to save them from Makassar and his army of Units. Escaping from the Units, the Doctor created a psychic projection of himself, which stole a Unit's mask and placed it over Makassar, trapping him in a mental feedback. (PROSE: The Masks of Makassar)

On a return trip to the Powell Estate, the Doctor, with Rose and Mickey's help, defeated the Quevvil, who were using video games to choose victims for their mind control missions into the bases of their enemies, the Mantodeans. (PROSE: Winner Takes All)

The Doctor took Rose to see the Mona Lisa at the grand opening of the Oriel, a transdimensional art gallery in the 37th century, only for the Doctor to find that all the humanoids in the gallery, including Rose, had been enslaved by an artist called Cazkelf. Cazkelf used the psychic energy of the visitors to send a distress signal to his people so he could return home, but the Doctor freed Rose and set up a feedback loop, returning the stolen psychic energy back to its owners. The signal was still successfully sent, but Cazkelf's people did not arrive at the Oriel. The Doctor took Cazkelf to his homeworld, which had been devastated by a disaster. Afterwards, Cazkelf returned to Earth. Expecting to face consequences, the materialisation of the TARDIS before the visitors made them believe this was all part of a performance art piece. The Doctor advised Cazkelf to "delight and amaze" them. (COMIC: Art Attack)

The Doctor took Rose on a cruise on 22nd century Mars, where the two were stowaways on the cruise ship holding a private wedding party of 143-year-old plutocrat Alvar Chambers. When Alvar ordered the Doctor to be thrown into the Martian sea, the Doctor's body was taken over by a body-stealing entity that ate people by feeding on their worst fears, putting them into a state where their identities would dissolve within it while they were dreaming. The entity tormented Rose with a nightmare of the Doctor coming back too late in Rose's life for her to be a companion and then sending it spiralling into ruins to spite her. Rose saw through this illusion and found the real Doctor trapped within the entity, tasking her with freeing its surviving victims while the Doctor dealt with the actual creature, although Alvar and his new wife Susannah didn't make it. As the creature required a stable image refracted in the air to sustain itself, the Doctor used the artificial air inside the cruise ship's air bubble to create a "tornado". The Doctor believed that it was still out there, waiting to happen again, but hoped this meant the humans would start treating Mars with respect now. (COMIC: The Cruel Sea)

The Doctor and Rose travelled to a Vandosian ship, saving Phil Tyson from execution by the Vandos Tribunal. While attempting to return Tyson to Earth, the Doctor was told Phil was a reincarnation of Shogalath, whom the Vandosians claimed was a monster for toppling the Vandos Imperium. While escaping, Phil saved the Doctor and Rose from the Bailiffs and made it to the TARDIS. The Tribunal threatened to destroy Great Britain if Phil wasn't handed over to them. They fired, but thanks to the Doctor's earlier efforts, the ship backfired on itself. Returning Phil home, the Doctor explained that Shogalath was in fact the leader of a peaceful revolt against the Imperium and a "hero". Phil departed their company with a new lease on life, seeking to make a good future for himself. (COMIC: Mr Nobody)

On a human colony planet, the Doctor and Rose were under attack by the rain, but Jack and Susie saved their life by bringing them into their shelter. The Doctor discovered the rain was a living creature with the ability to easily cleave through human flesh as it fell to the ground and it was killing off colonists in their downpour because the life form was being killed. He went outside, and persuaded the rain to stop, saving a family of colonists. With the family the last humans left of the devastated colony, the Doctor guided them home in their spaceship, and he also inspired their son, Andy, to become a space traveller. (PROSE: Pitter-Patter)

The companion who couldn't cut it
Tracking a distress signal, the Doctor went to the Vault in 2012 Utah, where he found a lone Dalek had survived the Time War and was being kept, amongst other alien artefacts, by Henry van Statten. Consumed by hatred, he took pleasure in torturing it, even as it begged for pity. The Dalek escaped by extrapolating Time Vortex radiation from Rose's DNA and, with no orders, chose to destroy everyone insight. With the Vault staff slaughtered, the Doctor prepared to kill the Dalek when it dropped it's defences, but Rose stood in his way. To the Doctor's shock, the Dalek committed suicide due to it's personality change making it deem itself an abomination.

Before departing, Rose asked the Doctor to invite Adam Mitchell, one of Van Statten's young employees who she had befriended, into the TARDIS as he had nowhere else. The Doctor left the TARDIS doors unlocked for Adam to wander inside as it dematerialised. (TV: Dalek)

The Doctor initially attempted to return Adam home but found the TARDIS knocked slightly off course by a temporal tsunami as they arrived in Birmingham 2012. He was then forced to wait 28 years after being displaced to 1894 so as to catch up with Rose, who was herself sent to 1922. The Doctor ultimately discovered that the anomalies were the work of the Bygone Horde, a collection of echoes of races erased by the Time War who attempted to return to reality at the expense of the human race. Impressed by Adam's assistance in thwarting the Bygone Horde, the Doctor decided to take him on as a companion, setting a course for the far future. (AUDIO: The Other Side)

For Adam's first real trip, the Doctor took his two companions to the Fourth Great and Bountiful Human Empire to see the human race at its zenith. Pretending to be management on the news broadcaster, Satellite Five, the Doctor and his companions found the Empire had been manipulated. Adam, suffering from severe culture shock, was left on his own.

Captured by The Editor, the Doctor and Rose found that the Mighty Jagrafess of the Holy Hadrojassic Maxarodenfoe had been controlling the human race from Satellite Five by manipulating information. Thanks to Cathica Santini Khadeni, one of the workers who learned of the truth, the satellite's heat was rerouted, sending heat to the Jagrafess's control room, freeing the Doctor and Rose and killing the Jagrafess.

Upon learning Adam was trying to learn about the future for his own gain, the Doctor evicted him from the TARDIS and took him home, leaving him with the forehead implant he got at Satellite Five as punishment. When Adam begged for another chance, the Doctor was unsympathetic to his plight. (TV: The Long Game)

Further adventures with Rose
The Doctor and Rose visited the Christmas truce of World War I, where the Doctor got the German and the British armies to play football on Christmas by using his psychic paper to pose as a FIFA referee, leading to a day of peace before they were forced to continue fighting. (COMIC: The Forgotten)

Taking Rose home once again, the Doctor saved the Powell Estate from Zargath and his invasion force by making it rain with the sonic screwdriver. Rose realised that Zargath's militia was allergic to water. (COMIC: Death to the Doctor!)

At Rose's request, the Doctor took her to her mother and her father, Pete Tyler's, wedding. After that, he took her to the church where Stuart Hoskins and Sarah Clark were to be wed in 1987, not far from where Pete died. Rose crossed the path of her past self, who was unable to go to Pete as he died, and saved Pete from a hit-and-run death. Rose's actions caused the TARDIS to be thrown off into the time vortex. Enraged by her actions, the Doctor suspected that she had only agreed to travel with him to save Pete and considered abandoning her in the past, though Rose insisted she hadn't planned it and the Doctor didn't go through with leaving Rose.

The Doctor, telling Rose and the wedding guests to rush inside the church, tried devising a way of stopping creatures from outside time that were attacking the Earth to seal off the paradox Rose had created. They reconciled; the Doctor admitting he wouldn't have really left. He started working on a way to repair the damage to the universe while leaving Pete alive for Rose. He used his TARDIS key, which was still linked to the TARDIS' interior, to bring the TARDIS back. However, after Pete accidentally made Rose hold her infant self, the Doctor sacrificed himself to the creature brought by the paradox and the creature was zapped by the key, interrupting the TARDIS' return. He was restored to life when Pete let himself get hit by the car (which was stuck in a time loop, awaiting him). Thanks to these events, the new timeline had Rose be there for her father when he passed. (TV: Father's Day)

Taking a break, the Doctor and took Rose to a cafe in Paris, France in the year 1923. As they ate their food, the Doctor entertained Rose by playing with the salt and pepper shakers at their table, while his three successors, who had also intended to eat at the café, looked on. (COMIC: Four Doctors)

The Doctor travelled with Rose to the Zaggit Zagoo bar on Zog. Rose mentioned that when she was twelve she begged her mother for a red bicycle for Christmas, but Jackie couldn't afford it. The Doctor left Rose at the bar, and went back in time to buy her the bike. The Doctor bought the bicycle from Hildreth's, but it was soon stolen by Jinko, who wanted revenge on the Doctor for a previous encounter. The Doctor followed him back to Jinko's junk yard, and used his sonic screwdriver to bring the whole place crashing down. The Doctor quickly grabbed the bicycle and left to deliver the bicycle to Rose's flat in time for Christmas. (PROSE: The Red Bicycle)

The TARDIS was forced down to London because of the presence of two Shadeys from another dimension, whom had brought Robert Greene, a rival playwright of William Shakespeare's, four hundred years into the future. After realising that Shakespeare was remembered in the future while Greene was not, Greene used the powers granted to him by the Shadeys, powered by his "negative energy", to spread rot across London. When the Shadeys discovered the Doctor's presence, they decided to toy with the Doctor by meddling with time and have Greene kill Shakespeare in 1592. Going back in time to protect the famous playwright and actor, the Doctor briefly took over Shakespeare's position on stage in the role of Richard III in the play of the same name. In return for relinquishing the power of the Shadeys and saving the world, the Doctor and Rose promised to remember Greene, and Green banished the Shadeys, returning to his deathbed where he was dying of plague. The Doctor lamented that the fate of being forgotten seemed to be unavoidable for anybody, but Rose gave him the reassurance no one would ever forget him. (COMIC: A Groatsworth of Wit)

Adam's revenge
After helping Drake Ayelbourne of Altair VII, the wealthiest man in the outer rim of the galaxy, with a robot problem, the Doctor and Rose were confronted by a cloaked figure, who revealed himself to be an older Adam Mitchell, who had sworn revenge on the Doctor after his mother had died from a brain illness because he could not use future technology to save her. Teaming up with, they kidnapped the most frequently associated companions of every incarnation of his original regenerative cycle, save his concealed wartime incarnation. (COMIC: Mystery Date)

However, Adam had a change of heart when the Master attempted to destroy eleven different versions of the TARDISes by overloading them with chronal energies he had stolen across the Doctor's timelines, also wiping out their respective incarnations. However, the energy would keep on growing out of control until it destroyed the universe and reality altogether.

Not wishing to cause this level of destruction, Adam turned against the Master. The Ninth Doctor saw Adam's dedication to changing his opinion of him and said to Adam that this was his chance to prove him wrong over his past mistakes. Adam stopped the Master's attempt at causing a cataclysm by blowing up the console controlling the release of chronal energies, but this act left him right in the fray of the resulting explosion. He died moments after making his sacrifice, forgiven by the incarnation of the Doctor he once disappointed. The Ninth Doctor mourned his death alongside his other incarnations and honoured him as a true companion on his memorial that they erected to remember him by. (COMIC: Endgame)

Joined by Captain Jack
The Doctor tracked a Chula ambulance to 1941 London, where, after Rose had wandered off, he discovered TARDIS phone ringing; on the other side, there was a boy asking for his mother. Investigating further, he followed Nancy, a homeless young woman who was feeding homeless children by stealing from people's meals that were still fresh on their tables, was being chased by a child in a gas mask. Nancy told the Doctor the "bomb that wasn't a bomb" landed near Limehouse Green station. Following Nancy's advice, the Doctor went to the nearby Albion Hospital. There, he found living dead creatures, with gas masks fused to their face, and identical symptoms, including a scar on the hand in the same place as the child that pursued Nancy.

Captain Jack Harkness, who had found Rose, tracked down the Doctor, thinking he and Rose were members of the Time Agency, and revealed the object was a Chula ambulance, which Jack himself had used to attract one of the agency as part of a con to sell half of the object right before a German bomb hit it, instead bringing the attention of the Doctor and Rose. (TV: The Empty Child) Jack teleported the Doctor and Rose to his ship, and they went to the bombsite near the hospital, where they realised the truth; Nanogene in the ambulance had reanimated a dead boy and, due to their unfamiliarly with humans, had spread the Empty Child virus. The ambulance started its emergency protocols, causing the creatures, who had been armed as "Chula warriors", and were ready to "tear the world apart" to find the boy's mother.

Every patient and soldier at the bombsite converged on the Doctor, Rose, Nancy and Jack. The Doctor fixed the nanogenes' mistakes by comparing the DNA of the child and Nancy, who was his mother, restoring the infected zombies to normal. Jack stopped the bomb from hitting the bombsite by placing it in stasis inside his warship and when everyone got to safety, the Doctor destroyed the ambulance, making sure that history said that a bomb hit that location. The Doctor rescued Jack from his Chula warship just before it exploded, taking him aboard the TARDIS as his latest companion. (TV: The Doctor Dances)

Memory fiasco
The Doctor wanted to take Rose and Jack to Excroth, only to find the planet destroyed, and them captured by the Lect, who demanded to know why the travellers had came to the Excroth System. As a squadron of armoured Unon attacked the ship, the Doctor attempted to lead Rose and Jack back to the TARDIS, but the three were intercepted by a group of Lect. Jack blasted off one of the Lect's arm so the three could escape in the TARDIS, though Jack and the Doctor inadvertently left without her as the ship exploded.

The Doctor and Jack tracked Rose down to the Fluren Temporal Bazaar on Fluren's World, a black market for time weapons, where they found Rose, who had been stuck there for four days after she fell through the Vortex with a tachyon inhibitor protecting her from the time winds until Glom picked her up with his ship's time scoops. The Doctor recognised Glom's weapons as being from Gallifrey, and flipped Glom's table in anger. In an attempt to attract the Unon, the Doctor announced to the crowd that he was offering his Time Lord mind for sale, but was transmitted aboard the Lect ship instead. When the Unon arrived and fought off the Lect, the Doctor made an attempt to talk to them, but was teleported to meet the Unon Mother Superior, Arnora, in a sub-dimensional void. The Doctor agreed to co-operate with the Unon in return for his TARDIS being retrieved. After reuniting with Jack, the Doctor and Jack fixed a time fissure on Traxis using a temporal stabiliser. The Doctor was contacted by Rose for his coordinates, which he gave to her, only to find that she had joined up with the Lect and led their armada to the Unon's Perpetual City.

When the Doctor was taken aboard the Lect command ship by Rose, he learned that the Lect were Excrothian survivors who wanted revenge on the Unon for destroying Excroth with a entropy engine for their time travel experiments. Realising that history would repeat itself, the Doctor decided to take the Lect leader, Prelon Marleth, to destroy the entropy engine and the Unon with it, telling a disagreeing Rose that it was "[Marleth's] war, [and] his choice." However, Marleth was shot by Arnora before he could ignite the engine, so the Doctor threatened to do it himself if the Unon refused to surrender. He was then saved by Jack and the Unon Grand High Seer, Evja, from an attack from behind, but could not stop the engine's meltdown, or Marleth and Arnora from killing each other. Taking as many as he could, the Doctor took Evja and the Unon to a new planet for a fresh start. (COMIC: Weapons of Past Destruction)

The Doctor took Rose and Jack to the Eye of Orion, but found a giant ziggurat and the Hanging Gardens of Slarvia, which had been destroyed centuries before. The Doctor used his sonic screwdriver to discover a ship in orbit, which transmatted them on board and brought them face to face with Taggani, the most famous geohacker in history. After lamenting about Taggani's use of his helmet, an Aesirian world-shaper, to overrun the planet Campra with Argurian creepers, Taggani used it to form a mind-link with the Doctor, discovering he was the same Time Lord mind put up for auction on Fluren's World and planned on using his memories to recreate everything lost in the Time War. However, the Doctor was able to enter Taggani's mind at the same time and discover that he was Brian Carrios, an art historian from the Braxiatel Collection who was expelled for being unable to spot forgery. The Doctor used the world-shaper to broadcast Taggani's true identity on the side of the planet, before transmatting himself, Rose, and Jack back down to the surface. As Judoon ships from the Shadow Proclamation closed in on Taggani's ship, Rose pointed out that Jack's face remained on the side of the moon. (COMIC: Hacked)

While in San Francisco, 2016, the Doctor met a future version of Mickey Smith, who had already met his next incarnation. Mickey had called the Doctor for help after his wife, Martha Jones had turned into a gargoyle. The Doctor discovered that a wormhole was passing through the city. That, coupled with the city's previous history had caused nearby humans to mutate. The Doctor and Mickey followed the wormhole back to Shirov-three, and discovered that Glom was behind the creation of the wormhole. The Doctor drove a large tourist bus through the wormhole when it was at maximum capacity, collapsing it whilst also sending him back to San Francisco. The destruction of the wormhole reversed the human mutations. The Doctor then called Glom on his phone and blackmailed him into launching a rescue mission for the stranded alien tourists. (COMIC: The Transformed)

Later, the Doctor, Jack and Rose found themselves on Earth, in the late 20th century. There, they met Tara Mishra, who later revealed herself to be a UNIT soldier. They went back to the UNIT research base, where they met the Brigadier. (COMIC: Official Secrets)

The Doctor was sent to Hesguard Institute following the alleged murder of Tara, in reality a ruse to allow him to investigate the inner workings of the facility after seeing news of former patients committing worse atrocities than before. There, he was placed under the Bad Wolf Process, meant to drain all of his negative emotions and thoughts into a vessel known as a Sin-Eater. The resulting creation of a Sin-Eater modeled after the Doctor soon proved destructive, as, due to the Doctor's telepathic abilities, the Sin-Eater developed a mind of its own and began rampaging throughout the facility with malicious glee, eventually granting the other Sin-Eaters sentience, Soon after, the Doctor reunited with Rose and Tara, and transported them to the Matryoshka drive, the source of energy running the Institute. He lured his Sin-Eater there, who began feeding on the Doctor's life energy but was soon sent into the Matryoshka drive via a teleport slipped onto him by the Doctor. Jettisoning the drive into the Void, the trio made their narrow escape to an examiner shuttle as the facility dissolved in the face the time storm surrounding it. As Tara and Rose discussed their dubious victory, the Doctor piloted their shuttle in silence. (COMIC: Sin-Eaters)

Final adventures
The Doctor intended to take Rose and Jack to the planet Kegron Pluva, but instead arrived in 2005 Bromley to investigate a time distortion. There, he encountered Das, a Neanderthal who was transported from 29,185 BC to 2005 by a rip engine, a crude method of time travel that prevented anyone who used it from travelling in time again. Unable to return Das to his native time zone, the Doctor and Rose left him in 2005 with Jack, and travelled to 29,185 BC to investigate further. There, they encountered a genius named Chantal Osterberg, who intended to wipe out humanity and replace it with Hy-Bractors. After stopping Chantal, the Doctor and Rose reunited with Jack, who had spent a month introducing Das to the ways of modern life, and resumed their travels together. (PROSE: Only Human)

When the TARDIS became unable to travel through time, the Doctor went to 2006 Cardiff so that the TARDIS could refuel via a scar in the rift that was closed by Gwyneth. Whilst in Cardiff, the Doctor and his two companions, joined by Mickey, captured Blon, the sole Slitheen survivor of the attack on Downing Street, who had become Lord Mayor of Cardiff.

Though Blon tried fleeing, the Doctor reversed her teleportation device several times until she gave up and took her prisoner aboard the TARDIS until he could return her to Raxacoricofallapatorius to face execution after her family had already been sentenced to death in their absence. The Doctor confiscated her extrapolator to use as a "power-booster" on the TARDIS and took her to a restaurant for dinner as her last request.

After he remained unmerciful towards her, Blon tried to tear the TARDIS and the Earth apart by making the extrapolator lock onto an alien power source that was refuelling on the rift, using the extrapolator as an interstellar surfboard to escape the Earth. However, the damage she caused to the ship opened the heart of the TARDIS, which turned her into a Slitheen egg. Realising Blon had a second chance in life, the Doctor decided to drop her off in the hatchery on her homeworld. (TV: Boom Town)

The Doctor, Rose and Jack next stopped off at a dull colony world, where all fiction was banned. They discovered that the locals had become confused, believing that fiction was true. He cured the population of "fiction madness", contracted from spores in the air. (PROSE: The Stealers of Dreams)

Receiving a message from his eleventh incarnation, the Doctor, Rose and Jack arrived on New Vegas in the 23rd century, where they intended to assist the police department investigate the Whisper, a strange vigilante that had terrorised the city's underworld. This involved Rose working undercover as a nightclub waitress and Jack as a reporter for the Daily Galaxy. (AUDIO: Night of the Whisper)

The Battle of the Game Station
After escaping from 1336 Kyoto, Japan, the Doctor, Rose and Jack were teleported to Satellite 5 to be put in deadly versions of TV game shows. After escaping Big Brother alongside a contestant called Lynda Moss, the Doctor met up with Jack and they raced to save Rose from The Weakest Link, hosted by a deadly Anne Droid; they were unsuccessful in preventing the Anne Droid from seemingly killing Rose. Completely broken, the Doctor, along with Jack and Lynda, was arrested for breaking in and out of the games. However, he and Jack physically overpowered the guards and set off to stop the "entertainment".

Taking hostages in the control room, Jack found the TARDIS stowed away in an archive room. Using the TARDIS, Jack discovered the laser that "killed" the games' losers was actually teleporting them across space. Puzzled, the Doctor discovered that the Game Station was unknowingly broadcasting a secondary signal to an empty location of space, which was where all the losers ended up. Disabling the signal, the Doctor and Jack were horrified to find two hundred Dalek battleships. Establishing contact, the Doctor learned his old foes had taken Rose hostage, but promised to rescue her and destroy the Daleks. (TV: Bad Wolf)

The Doctor and Jack flew the TARDIS straight into the Dalek command ship and rescued Rose. However, the Doctor soon discovered the Dalek Emperor had also survived the Last Great Time War; it had been shaping humanity for many centuries, converting the contestants into Daleks for its army. Knowing his fight against the Daleks was suicidal, the Doctor sent a reluctant Rose back to the 21st century in the TARDIS, while he and Jack gathered a possible resistance consisting of gameshow contestants and operatives. The Doctor built a delta wave generator, a device that would "fry the brain stems of every living thing within a thousand miles of the satellite", but was not able to perfect it to work only on Daleks.

After the resistance, including Lynda and Jack, were all killed, the Doctor proudly told the Emperor that he would rather be a coward rather than killer. Much to his surprise, Rose had opened the heart of the TARDIS and become the Bad Wolf entity. Having absorbed the energy of the Time Vortex into herself, she brought the TARDIS to the Game Station and scattered all the Daleks and the Emperor's atoms into dust, ending the Daleks' plot. (TV: The Parting of the Ways)

Death
The Doctor knew that Rose would burn up if she kept so much power in her body. He drew the time vortex from her body and into his with a kiss, before sending it back into the heart of the TARDIS. He took an unconscious Rose into the TARDIS, abandoning a resurrected Jack on the deserted Game Station (TV: The Parting of the Ways) after Rose had accidentally converted him into an immortal fixed point in time. (TV: Utopia)

Knowing that his brief possession of the vortex energy had caused cellular damage to his body, the Doctor told Rose that he had wanted to take her to so many places, such as the planet Barcelona. Trying his best to explain that he was about to regenerate, the Doctor told Rose she had been fantastic - "And you know what? So was I!" - then regenerated into his next incarnation. (TV: The Parting of the Ways)

Post-mortem
When the Tenth Doctor was confronted by Es'Cartrss within the TARDIS' Matrix, he summoned the Ninth Doctor, among his other past incarnations, to use their united memories and willpower to take back control of the Matrix. (COMIC: The Forgotten)

When under attack by an age-regression gun, the Tenth Doctor briefly retro-regenerated into his ninth self. Appearing to be in pain from the process, he briefly warned Dorothy Bell against struggling with the age-regression gun before the effects wore off and the Tenth Doctor re-emerged. (COMIC: The Fountains of Forever)

After the Eleventh Doctor was accused of committing deadly crimes against the Overcast, he brooded in the TARDIS for two days, imagining all his previous numbered incarnations, including the Ninth Doctor, interrogating him over the crimes. When he offered the rationale that he always left things better than he found them, they all turned and left him in disgust and disgrace. (COMIC: Pull to Open)

When the Then and the Now attempted to ingest the Eleventh Doctor's timeline, the Doctor once again briefly retro-regenerated back into the Ninth Doctor. (COMIC: Outrun)

When the Eleventh Doctor was attacked by the Then and the Now on Lujhimene, the Ninth Doctor was among the faces seen as the Doctor's timeline was almost destroyed. (COMIC: Running to Stay Still)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Ninth Doctor, appeared inside it to defend themselves as well. After listening to his predecessors defend themselves, the Ninth Doctor was quick to point out that auditor Sondrah was more interested in the Doctor than the planet he was meant to audit, a sentiment that the Tenth Doctor agreed on. When the Eleventh Doctor began to deduce Sondrah's true identity, the past Doctors faded away as Oscar Wilde interfered with the Nexus. (COMIC: Dead Man's Hand)

When Clara Oswald entered the Doctor's time stream, she saw the ninth incarnation among the Doctors that ran past her, with the Eleventh Doctor claiming them to be his "ghosts". (TV: The Name of the Doctor)

When he was exposed to energy from a time storm, the Twelfth Doctor degenerated through all of his previous incarnations, including the Ninth Doctor. (AUDIO: The Lost Magic)

Alternate timelines
When an alternate version of the Twelfth Doctor attempted to trap his post-Time War incarnations in various alternate timelines so that he could manipulate their minds to ensure his own existence, he was unable to target the Ninth Doctor. Since his plan involved presenting the Tenth, Eleventh and Twelfth Doctors with dark visions of possible alternates, the Tenth and Twelfth Doctors mused in the aftermath that he had left the Ninth Doctor alone because he was unable to find a timeline in which the Ninth was "anything less than fantastic." (COMIC: Four Doctors)

When the Cybermen at the end of the universe allied with Rassilon and took over Gallifrey, their influence spread in time to 2006 Cardiff. The Doctor, Rose, and Jack, robbed of the TARDIS, rescued Jackie Tyler from a cyber-converted jaguar in a flyer before heading over to the base of the Cybermen's operation. There, crashing through the side of the building, they attempted to regain control of the TARDIS, only to have the console explode, activating the Cloister Bell and nearly crushing the Doctor under a collapsed pillar. The TARDIS began imploding on itself to protect the Earth from its engines exploding, so the group evacuated to the flyer where its shields were still up. During the chaos, Rose was partially cyber-converted and killed Jack.

With Jackie safely in the shields of the flyer, the Doctor attempted to use his sonic screwdriver to confront the Cybermen and figure out how they converted Rose so fast, discovering an airborne element that cyber-converted his screwdriver into his hand, and began spreading up his arm. Leaving Jackie in the shield that would soon reject him, the Doctor attempted to return to the imploding TARDIS to collapse its containment field and allow the Eye of Harmony to rupture, destroying the Cyber-Earth with it. Before it could, the Doctor and Jackie discovered that the energy had been siphoned away, before everything reverted back to normal. Unbeknownst to the Doctor, his future incarnation allied with Rassilon to hijack the regenerative energy being stolen by the Cybermen, and sent it through the Eye of Harmony on Gallifrey to correct all that the Cybermen had changed. As Rose and Jackie embraced, having forgotten what they went through, the Doctor looked on somberly, contemplating what had happened. (COMIC: Supremacy of the Cybermen)

Personality
The Ninth Doctor was an emotional incarnation of great sorrow and anger, plagued by the outcome of the Last Great Time War. (TV: Dalek) Emotionally exhausted, he would break down when faced with pain, suffering, or death. (TV: The End of the World) A mercurial individual, he hid his sorrow with a façade of manic energy, sharp, offbeat wit and enthusiastic confidence, but would quickly drop the masquerade when deeply displeased. (TV: Rose, The End of the World, World War Three, Dalek, The Long Game, The Parting of the Ways)

Behind his angry demeanour, however, he was one of the more nobler incarnations, with not even the continuity bomb able to find a timeline where he was "anything less than fantastic", (COMIC: Four Doctors) and him willingly returning the power of the Time Vortex to the heart of the TARDIS after saving Rose from burning up by absorbing the power into himself, (TV: The Parting of the Ways) despite the Tenth Doctor claiming that a Time Lord would become a "vengeful god" if they absorbed such powers. (TV: Utopia) He would in fact laugh off the idea of being a god when Blon Fel-Fotch Passameer-Day Slitheen identified his TARDIS as "technology of the gods", musing he'd never get a day off. (TV: Boom Town)

Because of the emotional burden he carried with him, with wounds still fresh, he often made decisions in the heat of the moment without thinking them through, off emotion rather than logic, such as confronting the Nestene Consciousness with anti-plastic on his person, (TV: Rose) throwing himself in front of the Reapers as the "oldest thing in the room", (TV: Father's Day) and offering his Time Lord mind for sale on Fluren's World. (COMIC: Weapons of Past Destruction) He was also prone to falling for minor deceptions or overlooking obvious details, such as having to look at the London Eye several times before realising it was a transmitter, (TV: Rose) having his jacket stolen, (PROSE: The Clockwise Man) giving himself the alias of "Doctor Table" while trying to get a Neanderthal out of a hospital, (PROSE: Only Human) and locked himself in the cabinet room of 10 Downing Street to escape the Slitheen without considering how to get out to stop their plan. (TV: Aliens of London)

While he was more adept at noticing the flaws of humanity than his predecessors, (TV: Bad Wolf) the Ninth Doctor still retained the selfless and caring attitude that he carried throughout his previous lives, never once hesitating to put himself in harm's way to save those around him. (TV: The End of the World, World War Three, Father's Day, The Parting of the Ways, COMIC: The Cruel Sea) When he realised that he could reverse the pain and suffering he had encountered with the Empty Child plague, the Doctor became overjoyed, whooping how "just this once, everybody live[d]", with Rose Tyler claiming he was "beaming away like [he was] Father Christmas". Indeed, the Doctor himself noted he needed "more days like this", proclaiming that he was "on fire!" (TV: The Doctor Dances)

More aloof than other incarnations, the Doctor casually informed Rose Tyler of Wilson's death, (TV: Rose) failed to consider any discomfort the TARDIS translation circuit would cause, (TV: The End of the World) was willing to allow the Gelth to occupy dead human bodies, likening it to recycling, much to Rose's disgust, (TV:The Unquiet Dead) and treated people, like Mickey Smith, with disrespect if they got on his bad side. (TV: Rose, Aliens of London, World War Three) He could also be callous, which is shown when he refused to help a dying Cassandra, coldly saying "Everything has its time, and everything dies." (TV: The End of the World) However, he also had a strong sense of right and wrong, and didn't believe someone following orders was an excuse to do horrible things. (TV: Bad Wolf) Despite being identified as less of an interventionist in this incarnation, he was willing to help his friend Plex populate a planet with clones using the Chameleon Arch, understanding the pain Plex felt for the loss of his species in a freak singularity. (COMIC: The Promise) He also took pity on Cazkelf, who stole psychic energy from the visitors of the Oriel art gallery to send a distress signal to his now devastated planet, and brought him back to Earth to "delight and amaze" his gallery's visitors rather than punish him for his actions. (COMIC: Art Attack) He described himself to Lynda Moss simply as a traveler wandering through, in search of a quiet life. (TV: Bad Wolf)

He was also willing to change his opinion of others after they showed their potential, most notably with Mickey Smith. Initially believing him to be nothing more than dead weight, and claiming that he was choking on his words asking for Mickey's help, the Doctor nonetheless invited him along in the TARDIS after his help in defeating the Slitheen family, and entrusted him with a computer virus to delete all mentions of him from the Internet. (TV: World War Three) Encountering Mickey in 2016 San Francisco, where he and his wife Martha Jones were freelance alien fighters after their adventures with the Tenth Doctor, (COMIC: The Transformed) the Ninth Doctor was left with an even greater deal of respect for Mickey and was notably more pleasant with him in his next encounter, though continued teasing him to keep up appearances and not drastically alter Mickey's opinion of him. (TV: Boom Town) He also showed a similar attitude towards Jack Harkness, initially being dismissive of him due to being a conman and indirectly causing the Empty Child plague, before saving Jack from the bomb he'd taken onto his ship and inviting him along as a companion due to this noble action. (TV: The Doctor Dances) Even during his limited travels with Adam Mitchell, the Doctor admitted to Rose that he found him a "tiny bit fantastic" after he helped the Doctor defeat the Bygone Hoard, (AUDIO: The Other Side) and accepted him as a true companion when he sacrificed his life to defeat the Master's plan to end the universe, (COMIC: Endgame) despite previously kicking him out of the TARDIS for attempting to send information from 200,000 to his present day answering machine. (TV: The Long Game)

He held a commanding presence, being able to take charge of a group of soldiers who had only moments before held him at gunpoint as a trespasser, (TV: Aliens of London) assert his leadership over the panicking guests of Stuart Hoskins and Sarah Clark's wedding during a Reaper attack, (TV: Father's Day) and ordering the victims of the Empty Child to "go to [their] room" as if he were an angry parent. (TV: The Doctor Dances) He was unappreciative of being interrupted, such as when Joseph Green appeared to fart during his speech, (TV: Aliens of London) or when someone else tried to take command away from him, such as when Jack Harkness tried to lead their capture of Margaret Blaine. (TV: Boom Town) Upon encountering Alistair Gordon Lethbridge-Stewart during a trip to the past, the Brigadier noted that the Doctor had a newfound military mindset which had not been present beforehand. (COMIC: Official Secrets) Adam Mitchell identified this Doctor as a "soldier" compared to other incarnations. (COMIC: Prisoners of Time)

Because of his pragmatic approach to situations, he would at times brush off individual deaths to focus on the task at hand, and would even encourage others to do the same and mourn later, as was the case with both Mickey Smith's alleged death at the hands of the Autons and Stuart Hoskins' father being devoured by Reapers; in the case of the former, however, he believed Mickey to be alive but neglected to tell Rose in favour of keeping the "domestics outside". (TV: Rose, Father's Day) Truly, while the Doctor showed the ability to move past the deaths of those around him in the heat of the moment, (TV: Dalek) he remembered the lives lost and even took time to console the Forest of Cheem for the loss of Jabe's life. (TV: The End of the World)

The Ninth Doctor displayed a huge sense of authority against his enemies, willing to let them die when he felt it justified their actions, claiming that everything had its time and that everything eventually ended, (TV: The End of the World, World War Three, Boom Town) but was willingly to use diplomacy. (TV: Rose, The Unquiet Dead, The Empty Child) He showed a particular dislike for those who tried to justify their actions by saying they were only following orders, telling the female programmer she had "lost the right to even talk to [him]" when she tried to use that excuse. (TV: Bad Wolf)

Despite initially coming across as emotionally scarred and melancholy, the Ninth Doctor displayed a fun side from time to time, bobbing his head to Britney Spears' "Toxic" and failing to hide his laughter as Rose was "gifted" bodily saliva from the Moxx of Balhoon, (TV: The End of the World) enjoying a meal with Nancy and her children friends, (TV: The Empty Child) having a dance with Rose Tyler, (TV: The Doctor Dances) playfully returning the flirtations of Jack Harkness and enjoying some downtime in Cardiff with Rose, Jack and Mickey Smith. (TV: Boom Town) While discussing the grave consequences of the human race being fed constant reality television like sheep, he interrupted himself to ask Lynda if they still had the program "Bear With Me", chuckling about the celebrity edition where the bear got into a bath tub. (TV: Bad Wolf)

The Doctor expressed a keen interest in history, particularly Earth's, once claiming he travelled in time specifically so he could see history unfold. (TV: Aliens of London) He was also a fan of Charles Dickens, reacting with glee when he met the man, both admiring and criticising his work, (TV: The Unquiet Dead) and had a fondness for art as well, taking Rose to see the original Mona Lisa at the Oriel, (COMIC: Art Attack) and considered himself an admirer of geohacking rather than a critic, unless it was abused. (COMIC: Hacked) He was a vocal fan of bananas, carrying one in his pocket and calling them a "good source of potassium". (TV: The Doctor Dances) The Doctor also seemed a fan of television, watching it at the Tyler's flat and later telling Mickey that the TARDIS gets all the football games, (TV: Aliens of London) and talked about his favourite episode of reality TV show "Bear With Me" with Lynda. (TV: Bad Wolf) He also found pleasure in playing Mickey's video games, even briefly bonding with him over them. (PROSE: Winner Takes All) Sharing bacon sandwiches with Rose in a cafe, he voiced an admiration for ketchup that challenged brown sauce as his favourite condiment. (AUDIO: Retail Therapy)

He was overconfident about his plans, even when he didn't think they would work, (TV: Rose) and would occasionally boast or show shades of playful arrogance. (TV: The Parting of the Ways; PROSE: The Hungry Night) Preferring to remain unnoticed in the background, the Doctor would encourage others into acts of heroism, such as Rose Tyler, Mickey Smith, Cathica Santini Khadeni, Pete Tyler, Nancy, and Jack Harkness. (TV: Rose, World War Three, The Long Game, Father's Day, The Doctor Dances) However, he was unafraid to confront his adversaries directly. (TV: Rose, The End of the World, World War Three, The Long Game, Bad Wolf, The Parting of the Ways) While the Doctor never shied away from adventure and danger, even describing such as "fantastic" and running excitedly towards screaming, (TV: The End of the World, The Unquiet Dead) he voiced an admiration for the lives of Sarah Clark and Stuart Hoskins, and was shocked when they suggested they weren't important in the situation at hand. (TV: Father's Day)

Despite his more celibate nature, (TV: Rose, The End of the World) the Doctor would engage in some friendly flirting. (TV: The End of the World, Boom Town, Bad Wolf) He believed marrying for love was overrated, telling Rose she could "ask Lade Mary Wortley Montagu". (PROSE: Only Human) He did, however, care very deeply about Rose Tyler, being reluctant to put her in danger, (TV: World War Three) and was even willing to let a Dalek loose on Earth to keep her safe. (TV: Dalek) When the Daleks invaded Satellite Five, the Doctor sent her back home to protect her, and deliberately absorbed the time vortex energy in her to save her life, knowing full well that he would have to regenerate. (TV: The Parting of the Ways) While others believed them to be lovers, the Doctor himself neither confirmed nor denied an attraction towards Rose. (TV: Aliens of London, Dalek, Father's Day; PROSE: The Beast of Babylon)

When dared by the Dalek Emperor, the Doctor struggled with the decision to destroy the Daleks and the Earth or simply allow the Daleks to kill him and take over the universe. In the end, the Doctor couldn't bring himself to destroy the Earth, even to rid the universe of the Daleks. (TV: The Parting of the Ways) During these events, the Doctor, in spite of being identified by himself and the Dalek Emperor as a "coward", had truly upheld his honour code of never being "cruel or cowardly". (TV: The Day of the Doctor, Listen) With this decision, the Doctor had proven that he had become a better man than he was when he last encountered a Dalek, whom he had tortured sadistically. (TV: Dalek) The Ninth Doctor frowned upon violence, and voiced a hatred of guns, but found fantasy violence in the form of video games somewhat therapeutic. (PROSE: Winner Takes All)

When forced the reflect on his memories of the Last Great Time War, and his war incarnation, the Doctor reacted in agony, showing a great dislike of his immediate predecessor, as well as his eighth incarnation. (COMIC: Weapons of Past Destruction) While the Tenth Doctor believed he had become rude compared to the manners of the Ninth Doctor, (TV: The Christmas Invasion) he came to hold a somewhat low opinion of his immediate predecessor, considering him to be violent due to being "born in battle", (TV: Journey's End) though a Matrix projection of this incarnation would refer to his successor as "fantastic". (COMIC: The Forgotten) The Eleventh Doctor seemingly harboured no such ill feelings, cheerfully delivering a message to the Ninth and signing off with a jovial "Cheers, Ears" before apologising for the joke with concern. (AUDIO: Night of the Whisper) The Twelfth Doctor would later claim that his ninth incarnation was so "fantastic" that there was no possible timeline that even the continuity bomb could find where he was anything but so, a sentiment shared by the Tenth, and later Eleventh, Doctor. (COMIC: Four Doctors, The Promise)

When talking about his possible death in a holographic message, the Doctor showed no concern for his demise, only hoping for a good death. (TV: The Parting of the Ways) Indeed, while he was dismayed at the idea of being killed by the Gelth in a Cardiff dungeon, (TV: The Unquiet Dead) when he believed the Daleks were going to exterminate him, his only reaction was to close his eyes and wait for the end. (TV: The Parting of the Ways)

After the regeneration process was started by the cellular damage he had achieved from siphoning the time vortex out of Rose's body, the Doctor first stated his regret at being unable to take Rose to Barcelona, and then speculated what he would look life after he regenerated. In the closing moments of his life, though, the Doctor made peace with his past actions, smiling from ear to ear before he regenerated. (TV: The Parting of the Ways)

Habits and quirks
The Ninth Doctor spoke with a distinctive Northern English accent, (TV: Rose, World War Three) and had a fondness for saying "fantastic" when he was pleased with something, (TV: Rose, Aliens of London, Father's Day, The Doctor Dances) came across a dangerous situation, (TV: The End of the World) saw something of interest, (TV: The Unquiet Dead, Boom Town) was sarcastically expressing displeasure, (AUDIO: Night of the Whisper) or when he was describing a favoured place. (TV: The Long Game, The Parting of the Ways) While his previous incarnations were rarely heard uttering curse words, the ninth incarnation used minor curses more freely, (TV: The End of the World) and was known to use "oi" to get people's attention. (TV: The Unquiet Dead) Nevertheless, this incarnation's TARDIS had a swear filter nested in the translation circuit. (PROSE: Only Human)

Like his first and seventh incarnations, the Ninth Doctor was often critical of human nature, calling humans "stupid apes", especially when angered by their actions, (TV: Rose, Father's Day) and, on one occasion, "brainless sheep". (TV: Bad Wolf) He also displayed a certain level of childish joy when it came to toying with people emotionally, such as addressing them by the wrong name or insulting their intelligence. (TV: Aliens of London)

He did not "do domestic", as he put it, which led to tension in his interactions with Jackie Tyler, (TV: Aliens of London, World War Three) and rarely spoke of his past to others. (TV: The End of the World) He would often make dry jokes to diffuse the tension of those around him. (TV: The Unquiet Dead)

The Ninth Doctor had a habit of folding his arms and frowning when lecturing or listening intently. (TV: Rose, The Long Game, Father's Day, Boom Town) He would also grin when happy, (TV: Rose) or when he found something funny. (TV: Boom Town) He also made a habit of lounging when sitting down, propping himself up on an arm. (TV: The End of the World, The Long Game, Bad Wolf)

He often gave speeches about things, (TV: Rose, The End of the World) or lectured those he wished to scold. (TV: Father's Day) He also voiced an affection for hugs, (TV: The Long Game) and gave them out to comfort others, (TV: Father's Day) or when in moments of joy. (TV: The Doctor Dances, Boom Town, Bad Wolf)

When offered coffee, the Doctor took it with just milk, (TV: Rose) and according to Gwyneth, he liked to have two sugars with his tea. (TV: The Unquiet Dead) He happily accepted turkey while dining with young orphans, (TV: The Empty Child) and ordered steak and chips while dining with Margaret Blaine for her last meal. (TV: Boom Town) Dining with the Tylers at their flat, the Doctor ate three sandwiches, two cakes, and two cups of tea, showcasing something of a large appetite. (PROSE: Winner Takes All)

Like his other incarnations, the Doctor had his TARDIS key with him at all times, but also carried a spare placed on a chain with a D-shackle, given to Rose Tyler. (TV: Aliens of London) He also began habitually carrying his psychic paper around, (TV: The End of the World) a trait that remained in his successors. (TV: New Earth, The Eleventh Hour, Listen) The Ninth Doctor otherwise broke away from the behaviour of his other incarnations, whose pockets were usually filled with seemingly random objects and knick knacks, by carrying very little on his person, with only his sonic screwdriver on him when frisked by security. (TV: Bad Wolf) However, he would at times carry small utility items like a scalpel, a paper and pencil, and opera glasses, (PROSE: Winner Takes All, TV: The Empty Child) as well as an occasional apple or banana. (PROSE: Winner Takes All, TV: The Doctor Dances)

Skills and abilities
The Ninth Doctor had a gift for taking charge of others, (TV: Father's Day, The Doctor Dances, The Parting of the Ways) even those initially hostile towards him. (TV: Aliens of London, Bad Wolf) He could also convince others he was needed as a leader for the benefit of survival. (TV: Dalek) However, he did not seem as skilled at holding audiences, being heckled while stepping in for Shakespeare onstage, (COMIC: A Groatsworth of Wit) and being treated as a comedy act in a makeshift cabaret when attempting to ask about a Chula ship falling from the sky. Although, he could amuse and hold the attention of a group of children, (TV: The Empty Child) and took a bow to roaring applause when he appeared on stage in the middle of a theatrical production in 1894 Birmingham, being sent back in time by the Bygone Horde. (AUDIO: The Other Side)

The Doctor was skilled in physical combat, being able to wrestle the head off an Auton copy of Mickey Smith, (TV: Rose) effectively fight against an Auton army, (COMIC: Endgame) hold his own against Idris Hopper, (TV: Boom Town) and throw a guard against a wall whilst breaking out of prison. (TV: Bad Wolf) He also showed a great deal of strength and agility, being able to avoid the attack of three Elians, (PROSE: The Red Bicycle) easily manoeuvre through the chaos of Traxis, (COMIC: Weapons of Past Destruction) rip the arm off of an Auton and hold it down in order to deactivate it, (TV: Rose) kick open a locked door, (TV: The Unquiet Dead) break out of his metallic restraints, (TV: The Long Game) and grab onto the underside of a passing spaceship that his imposter was flying. (COMIC: Doctormania)

Being a Time Lord, the Doctor could also slow down his perception of time through sheer concentration, being able to pass through a spinning blade as a result, (TV: The End of the World) and withstand electrical forces that were harmful to other species. (TV: World War Three) He also showed the ability to suck the power of the Time Vortex out of Rose Tyler with a kiss. (TV: The Parting of the Ways) He also displayed psychic abilities, telepathically placing Rose in a dreamscape of the Powell Estate from his memories before stealing energy from Makassar's gestalt to create a projection with physical substance, overpowering him, (PROSE: The Masks of Makassar) and confronted the entity using him as a host body within his mind before projecting his consciousness into the TARDIS to act as his vessel. (COMIC: The Cruel Sea)

He was also skilled at video games, (PROSE: Winner Takes All) knew how to handle explosives, (TV: Rose, The Doctor Dances) and could be a capable swordsman when the situation called for it. (PROSE: What I Did on My Christmas Holidays by Sally Sparrow) Despite being bad at card tricks, (TV: Rose) he was a good pickpocket, swapping Jack's sonic blaster with a banana. (TV: The Doctor Dances) He was also successful at riding a motorbike, quickly took command of a horse drawn carriage, (COMIC: The Love Invasion) and rode a dinosaur on Clix. (COMIC: Doctormania) Despite some initial confusion, the Doctor proved to be a skilled dancer. (TV: The Doctor Dances)

The Doctor could recognise substances such as ozone from smell alone, associating it with the "distinctive tingle" of teleportation, as well as tell it apart from chronon energy, (PROSE: Winner Takes All, The Red Bicycle, COMIC: The Bidding War) was able to tell that the Lend-a-Hand girls didn't "smell human", (COMIC: The Love Invasion) and was able to easily track Nancy without her detection, jokingly claiming his nose had "special powers". (TV: The Empty Child)

After having energy drained from him by a Glubby Glub, the Doctor found that he was now short sighted and pondered if he needed glasses. (AUDIO: Retail Therapy) This seemed to have no effect on his reflexes as a whole, however; when he took Blon Fel-Fotch Passameer-Day Slitheen out for a last meal, the Doctor showed keen reflexes by catching a poisoned dart-like projectile in mid-air with his fingers without even looking up from his menu, and repelling her exhaled poison with some mouthwash before she could exhale the full force of her fatal breath. (TV: Boom Town)

Intellectually, he was capable of mentally narrowing down a list of five thousand planets within a matter of seconds by focusing on the characteristics of the Slitheen family, (TV: World War Three) and had the technical skills to make Satellite Five into a Delta wave generator in a few hours despite initially predicting it would take at least three days given its size. (TV: The Parting of the Ways)

Appearance
Standing over six feet tall, (PROSE: Winner Takes All) the Ninth Doctor looked like a man in his early forties, (TV: Aliens of London) and had pale blue eyes, a small beauty mark on his right cheek, and dark brown hair, which he wore close-cropped. (TV: Rose) At times, he sported a five o'clock shadow, (TV: Rose, The End of the World) and was said to shave. (TV: The Doctor Dances) He was considered attractive by the likes of Jackie Tyler, (TV: Rose) Jabe, (TV: The End of the World) and Shirley Gilbert, who described him as "[a] bit of a dish if you like them rough", and his eyes as "dreamy"; (COMIC: The Love Invasion) "The Doctor" was awarded Cosmopolitan's "Sexiest Planetary Saviour" nine years in a row while using a skin suit based off this incarnation's appearance. (COMIC: Doctormania) The Doctor himself felt his appearance made him look much tougher, especially compared to to his eighth incarnation. (PROSE: The Red Bicycle)

He had large ears, which he was initially shocked at when looking at his reflection, (TV: Rose) causing Mickey Smith to nickname him, "Big Ears". (TV: Boom Town) Ironically, before his regeneration, his previous incarnation hoped that his successor's ears would be less conspicuous. (TV: The Day of the Doctor) When the Doctor told Nancy that his ears had "special powers", she asked him if his nose had powers too, implying that she thought his nose was large as well. (TV: The Empty Child) The Tenth Doctor also considered his predecessor's nose large, even nicknaming him "Big Nose", (COMIC: Four Doctors) while the Eleventh Doctor playfully teased him about his ears. (AUDIO: Night of the Whisper) Revealed in a story the Twelfth Doctor told Bill, the Ninth did not believe his ears suited him, but "we work with what we have." (COMIC: The Promise)

The Ninth Doctor was described by the Eighth Doctor as a "wiry man with a gaunt, hawk-like face, piercing, pale grey-blue eyes and a thin, prominent nose." (PROSE: The Tomorrow Windows)

Main attire
A less flamboyant incarnation, the Ninth Doctor opted for a more stripped down and rugged attire. The main staple of his outfit was a battered black double breasted leather jacket, (TV: Rose) though on at least two occasions, the jacket appeared brown in colour. (COMIC: Mr Nobody, The Cruel Sea) Similar in style to his two immediate predecessors' leather jackets, (TV: The Name of the Doctor, AUDIO: Fugitives) this one was distinguishable through its comparison by Jack Harkness to those worn by German U-boat captains. (TV: The Empty Child)

The Doctor was particularly fond of the jacket and rarely went without it, even if it clearly stood out as an anachronism in certain time periods; both Rose Tyler and Jack Harkness pointed this out on separate occasions. (TV: The Unquiet Dead, The Empty Child) Rose also noted that, during a situation in which both his jacket and the TARDIS went missing, he seemed more concerned with locating the former than the latter. (PROSE: The Clockwise Man)

Along with the jacket, he wore a number of v-neck jumpers, coloured in white, (COMIC: The Promise) plain maroon, (TV: Rose) navy blue, (TV: The Unquiet Dead) military green, (TV: Dalek) dark purple, (TV: The Empty Child) bright lilac, (COMIC: Weapons of Past Destruction) grey, (COMIC: Official Secrets) and plain black. (TV: Bad Wolf) Completing the ensemble were a pair of trousers, either black, (TV: Rose) grey, (COMIC: Weapons of Past Destruction) or navy blue in colour, (COMIC: Doctormania) along with a black leather belt, (TV: Dalek) a pair of black leather Dr. Marten boots, (PROSE: The Red Bicycle) and a black, strapped wristwatch, (TV: Rose) which he often looked at to find out dates and years, (TV: The End of the World, Aliens of London, The Long Game) and that the TARDIS was able to home in on while flown by Sally Sparrow. (PROSE: What I Did on My Christmas Holidays by Sally Sparrow) He also wore diamond-print socks. (PROSE: Winner Takes All)

Both Charles Dickens and Honoré Lechasseur compared the Doctor to a navvie. (TV: The Unquiet Dead; PROSE: The Albino's Dancer) Jackie Tyler was particularly critical of the Doctor's stripped down clothing style, believing he either owned only one T-shirt or threw them out after wearing them once. (AUDIO: Retail Therapy)

Other clothes
Whilst at the launch of the RMS Titanic in 1912, the Doctor wore a red cravat with a white shirt and black double-breasted frock coat. (TV: Rose)

While in 1924 London, the Doctor wore a dark brown round neck shirt under his jacket, with a pair of faded slacks, and battered shoes. (PROSE: The Clockwise Man)

He was also photographed wearing a navy blue polo-neck jumper at the John F. Kennedy assassination. (TV: Rose) Whilst in 1923 Paris, he wore a green crewneck sweater. (COMIC: Four Doctors)

During an adventure in World War I, the Doctor wore a military trenchcoat to fit in with the British soldiers. (COMIC: The Forgotten)

The Doctor and Jack Harkness briefly donned skin suits of Raxacoricofallapatorians when searching for Rose Tyler and Slist Fayflut Marteveerthon Slitheen on Clix. (COMIC: Doctormania) During his imprisonment at Hesguard Institute, the Doctor wore an orange prison jumpsuit. (COMIC: Sin-Eaters)

Casting
Originally, Russell T Davies approached Hugh Grant, who previously played the Doctor's alternate twelfth incarnation in the spoof The Curse of Fatal Death, to play the Ninth Doctor. He turned down the role, thinking the show would not take off. He expressed deep regret over this in 2007 after seeing how successful the show had become.

The Brilliant Book 2011
The non-narrative source The Brilliant Book 2011, which this wiki does not consider a valid source, stated that in 1944, the Ninth Doctor took Winston Churchill on a trip to ancient Rome, where they encountered a creature disguised as one of Emperor Tiberius's reclining benches. Winston then realised why the Second Doctor had taught him how to address a table in Latin back in 1882.

whoisdoctorwho.co.uk
The website whoisdoctorwho.co.uk had a list of sightings of the Doctor from which people had ostensibly been submitting to Clive Finch, a conspiracy theorist character from TV: Rose, who had pictures of the Doctor's ninth incarnation on the website, asking if anyone had seen him.

A submission from Steven Hudson claimed that Steven saw the Doctor "a couple a years ago" [sic] wearing an Edwardian outfit, rather than his usual leather jacket, but still the individual in Clive's photographs — the Ninth Doctor. He saw the Doctor wandering around a building development on Totter's Lane. According to Steven, he was muttering "They're all gone, I'm the only one left", alluding to the Doctor's involvement in the Last Great Time War.

A submission from H.J. Hardeman claimed to have seen "someone very much like him about a year ago". He had tried swapping "Edwardean gear" [sic] at an Oxfam in Sheffield for a pair of jeans and trainers.

A submission from Richard J. Kingston vividly recalls seeing the Ninth Doctor. In the summer of 1962, Richard had been working at a psychiatric institution when the Doctor was admitted inside. Prior to his arrival "a number of strange 'incidents'" had been happening where there fights between the staff and their wards. After a week of incarceration, where the Doctor easily escaped sedation and capture, he vanished. Richard had "no idea" how the Doctor escaped, but suspected a connection between his escape and the disappearance of the psychiatric ward's head, Dr Sirius Drake, and a "mysterious fire" that destroyed Dr Drake's private quarters and laboratory the same night. He warned to be aware of him and not to trust or follow him.

A submission from a "Matthew" said he saw the Doctor on a trip to Chepstow Castle. Matthew's tour guide mentions how people attacked the castle, when afterwards, "a man with short hair, a leather jacket and a northern accent" said, "I didn't see them do it that way". Later on, the people on the trip heard "a strange noise like some sort of engine".

A submission from Helva Soprano said that "this guy" did contract work for her firm of architects "last summer". She said that his designs were unusable, as the "doofus" kept making floor plans that were bigger than the outside of the building.

A submission from "trevor french" was "certain" that "20 years ago", "this guy" worked at the Planetarium at London. On a school visit to the Planetarium, trevor sighted him. trevor said that he "kept talking" about Halley's Comet and gave everyone orange fruit gums.

A submission from "blue" recounted that while travelling in Tibet "several years ago", blue remembered thinking to himself that "backpackers dont wear leather jackets" [sic]. The man blue saw was in "deep conversation" with some Buddhist monks, whom he was "surrounded by", and they "seemed to listen to everything he said". blue bumped into the man again "outside the monastry outside Lhasa" [sic]. He grinned at him and said, "keep on going. you will see" [sic].

A submission from Peter D claimed that Peter spotted the Doctor during the "Royal Wedding". He said to check the footage in the background near one of the OB vans, and to also check footage from Aintree over 100 miles away less than an hour later. Peter identified the individuals in the footage as the same man. He also saw him the previous day near the OB unit at "St Peter's, funeral". As well as this, he saw a blue box behind the stands.

A submission from Ted Prendergast sighted him posing as a photo-journalist in "the north east" in the mid-1990s.

According to a submission from Marcus Butler, a bloke in a leather jacket, described by Marcus as the "spitting image" of the man in Clive's photo, would turn up to to Marcus' father's skiffle band in the 1960s while they were busking. He said that the man would "turn up, take out his spoons and play along with the band". Marcus claimed that the man would have to have been in his 70s "now".

A submission from Richard Kilpatrick claimed that at a concert in 1987, he swore he saw the Doctor playing guitar in a session band for one of 's support acts. Richard said that the Doctor kept "frantically" looking at one of the exits and that soon after, "mysteriously left the band".

A submission from Terrance Chua stated that while researching the American Civil War at the University of Georgia, Terrance had found a picture from the Battle of Gettysburg in 1863, where a man in a Union Army captain's uniform was standing next to a converted field hospital "that looked slightly out of place". What puzzled Terrance was that in these photographs, he saw another photograph of "apparently the same man", with a bandaged arm, but this time wearing a Confederate colonel's uniform. He said that both looked exactly like "this Doctor".

A submission from Chris Steel simply said, "I believe I saw this gentleman on "Survivor" on American television".

A submission from Julie B said that there was a statue in "the Egyptian museum" that bore a striking resemblance to the Doctor and that it was made in 2500 BC.

A submission from "j q public" had sighted "someone who looked like him" arguing with "a little man with an umbrella" on a university campus.

A submission from Gerard Shannon mentioned his visit to a Megalithic tomb in Newgrange in County Meath "recently". Gerard was with a group of his friends, when he saw "this guy" walking out of the tomb with "some blond haired girl" [sic]. The man Gerard identified as the Doctor said "... well not to worry! They're trapped down there for another 5000 years!" Gerard initially thought they were just "some kind of archaeologists", but had his mind opened upon reading Clive's website.

A submission from Charlie Pocket stated that during his Las Vegas wedding in 1992, he was in a hurry to find a best man and a witness, so he "grabbed the first couple who passed by". He said it was uncanny how similar the man looked to the Ninth Doctor on Clive's website and that he was with "a blonde haired girl of about 19 or so". Charlie said that the best man's signature on his marriage certificate was "Doctor John Smith".

Other matters
"I sort of knew that he wouldn't. I know Chris a bit. I did a couple of meetings, and there was a moment, I suppose, a giddy moment where [I thought] 'Would he actually do it?' This wasn't the kind of decision he took in a funk or that he was cross. He was very measured, very kind, very gentlemanly about it. He's a good bloke. If you look at Chris's career, this is not what he does. The Ninth Doctor turns up for the battle and not the party."
 * The Ninth Doctor was dubbed in German by Frank Röth, in French by David Manet, and in Japanese by Katsuyuki Konishi.
 * With only one season, the Ninth Doctor's television run is the third shortest, behind that of the Eighth Doctor's two appearances in the 1996 made-for-television movie Doctor Who and the mini-episode; The Night of the Doctor, as well as the War Doctor's two appearances in the television episode The Name of the Doctor and the fiftieth anniversary special The Day of the Doctor.
 * The Ninth Doctor is only one of two incarnations to date to have the same companion throughout all his television appearances (Rose Tyler); he shares this distinction with the Eighth Doctor, who had only one companion - Grace Holloway - in the 1996 movie Doctor Who (discounting his reappearance in TV: The Night of the Doctor, where he travelled alone and mentioned companions that had not been seen on screen, but in the Big Finish Doctor Who audio stories). In spin-off fiction, it's established that the ninth incarnation had several adventures before meeting Rose, as well as having travelled alone before coming back for her, but it is ambiguous as to whether or not he took on companions during those spans of time.
 * With the total sum of TV, novels, comics and other media, the Ninth Doctor stands out as having the shortest era of any non-current Doctor.
 * The Ninth Doctor is one of three incarnations whose main attire does not include any form of neck wear, alongside the Fifth and Twelfth Doctors. The Ninth is also to date the only Doctor whose main attire excludes collared shirts as well, opting instead for long sleeve V-neck jumpers exclusively.
 * The ninth incarnation was the first never to face another Time Lord as an opponent on screen. As of 2013, the only other incarnation to share this distinction is the Eleventh Doctor, unless the Dream Lord or Mr Clever are technically considered to be Time Lords, each being an amalgam of the Doctor; or Melody Pond, who had Time Lord traits and served as the antagonist in Let's Kill Hitler, is counted. However, both face off against in Endgame, meaning every incarnation has had a Time Lord opponent in some form of media.
 * The ninth incarnation's era, due to its short length, stands as the first incarnation's era to be completely released to DVD in Australia, North America and the UK. The single film that made up the eighth incarnation's era was not available in North America and Australia at the point when Series One was released.
 * As of 2015, the Ninth Doctor is the only incarnation who has yet to be seen on Gallifrey in any chronicled adventure. Every incarnation before him has visited Gallifrey multiple times, the Tenth and Eleventh Doctors find themselves there in The Day of the Doctor, and the Twelfth Doctor finally made his way back to his home planet in Heaven Sent. The Tenth Doctor's comment in Journey's End of his predecessor being "born in battle", however, suggests that this incarnation has false memories of being present on Gallifrey (due to suppressing the memories of being the War Doctor), and he is alongside his other incarnations in The Day of the Doctor to save Gallifrey, confirming he's at least been in the planet's orbit.
 * The ninth incarnation is also unique in being the only Doctor to not be seen immediately after his regeneration. The Day of the Doctor shows the beginning of the transformation from the War Doctor to the Ninth, but is cut off before the full results are shown.
 * The original plan for The Day of the Doctor was for the Ninth Doctor to be the one who fought in the Time War, as hinted throughout his era. However, Steven Moffat admitted that he had difficulty with this since the Ninth Doctor is clearly "a new man" at the beginning of his adventures with Rose. (He makes several comments about his physical appearance upon looking in a mirror, indicating that he has recently regenerated and not yet gotten used to his appearance.) Though Christopher Eccleston enjoyed his time as the Ninth Doctor, he declined a part in the 50th anniversary special. When Eccleston turned down the offer to return, as Moffat thought that he would, the character of the War Doctor was created to take his place. Moffat later explained Eccleston's reasons for passing on the reprisal in an interview:
