Ninth Doctor

The Ninth Doctor was the ninth incarnation of the Time Lord known as the Doctor. Coping with the nightmarish events of the Last Great Time War, he tended to brood and act crossly to those who rubbed him the wrong way. Despite this, he remained jovial and quite friendly towards anyone he took a liking to. Rose Tyler was his most constant companion, although he did share several adventures with Jack Harkness as well. Absolutely definitive statements about the origins of the Ninth Doctor were complicated, however, by a lack of knowledge about his precise contributions in the Time War and the circumstances in which he regenerated from his predecessor.

During the Slitheen's attempt to destroy the Earth for profit, he gained temporary allies in Rose's mother Jackie, Rose's ex-boyfriend Mickey, and Harriet Jones. He also had a single adventure with Adam Mitchell, an employee of Henry Van Statten, at Rose's request.

He regenerated after he directly absorbed time vortex energy that had converted Rose briefly into the Bad Wolf entity. Though this saved her, it caused massive damage to his body at the cellular level.

Foreshadowing
When the Eighth Doctor looked into the Tomorrow Windows, he saw the Ninth Doctor as what he might look like after his next regeneration. (PROSE: The Tomorrow Windows)

Born in battle
The exact circumstances behind the Doctor's eighth death are unknown. The Doctor's tenth incarnation stated that he had been alone when he died. He stated that his eighth incarnation's demise had been caused by the events of the Last Great Time War. (COMIC: The Forgotten)

The Tenth Doctor later stated that his ninth self was "born in battle". (TV: Journey's End)

Early adventures
The newly regenerated Doctor had some adventures on his own. (PROSE: The Eyeless)

In 21st century Istanbul, the Doctor fought Sontarans in a sword fight. "Some sort of spy" called Sally Sparrow had saved the Doctor from the second one. She gave him her Christmas homework from 2005, and told him to keep it on him at all times.

Landing in a garden shed in Devon on Christmas Eve 1985, the TARDIS "burped", jumping forward in time twenty years. Reading Sally's homework, he 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. She spoke to the recording that her self from two hours in her past would watch, and told 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)

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)

The Doctor tended to Honoré Lechasseur's injuries after a bunker exploded in 1951. He disappeared without a trace. (PROSE: The Albino's Dancer) Clive Finch had several images of this incarnation at historical events. The Doctor appeared in Dallas at 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)

The Doctor, along with his other eleven incarnations, attended Alistair Gordon Lethbridge-Stewart's funeral. (PROSE: The Gift)

Meeting Rose Tyler
In the London shop, Henrik's, the Doctor pulled employee Rose Tyler away from Autons that were about to kill her. He warned Rose he was going to use explosives against the relay the Nestene Consciousness was transmitting to the Autons and told her to run. When she left the shop, the Doctor blew up the store, but he managed to escape.

A day later, the Doctor tracked the signal from the amputated arm to the Powell Estate, a council estate where Rose lived. After saving her from an Auton's arm that was meant to attack him, the Doctor left in his TARDIS, telling Rose to forget him. (TV: Rose)

Adventures with Rose
The Doctor ran into Rose again when he saved her from an Auton duplicate of her boyfriend, Mickey Smith, and he pulled off the Auton's head. Escaping from the Auton Mickey's rampaging body, the Doctor and Rose entered the TARDIS, where the Doctor used the head to trace the 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 toxins. It refused, and ordered two Autons to take the Doctor prisoner and confiscate the anti-plastic he was holding.

Unable to escape the Nestene Consciousness' base without access to the TARDIS, Rose kicked the Autons, and the anti-plastic, into the vat containing the Nestene Consciousness. This saved the Doctor's life, and destroyed the Consciousness. Taking Rose and Mickey to safety in the TARDIS, the Doctor asked Rose to travel with him, but specifically noting that Mickey was not invited due to his cowardly nature. Rose rejected his offer at first, but she later accepted when he told her the TARDIS was capable of travelling in time as well as space. (TV: Rose)

For her first voyage, the Doctor took Rose to Platform One in the year 5,000,000,000 to observe the Earth's destruction by the sun. After finding metal spiders were sabotaging the platform and killing the staff, he caught one, which led back to the "last human", Lady Cassandra O'Brien.Δ17. As a backup plan, Cassandra used her spiders to disable the platform's safety and teleported away to profit from the deaths of the visitors through the shares she held.

At the cost of Jabe of the Forest of Cheem's life, the Doctor restarted the platform's safety and saved the other visitors' lives. He teleported Cassandra back and let her frame of skin dry out and explode as punishment, showing her no mercy even when Rose asked him to help her. (TV: The End of the World) The frame of skin exploded, though Cassandra's brain meat survived. (TV: New Earth) Comforting Rose about the Earth's "death", he faced his own demons by telling her about the Last Great Time War, and how he was the last of the Time Lords, which had left him a very damaged man. (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. The Doctor met one of his idols, Charles Dickens. When Rose was kidnapped by Sneed and Company funeral parlour, the Doctor allied with Dickens to find her, following Gabriel Sneed and Gwyneth there, where other "zombies" had also been animated by the Gelth.

In the morgue, the Doctor had Gwyneth try and pull the Gelth through the Rift using her psychic connection to it from a young age. The Gelth, numbering in the billions rather than just a few, wished to wipe out humanity and take over their bodies. 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. After this, the Doctor said goodbye to Dickens, telling him that his work would be remembered for centuries to come. (TV: The Unquiet Dead)

The Doctor and Rose visited the Christmas truce of World War I, where he got the German and the British armies to play football on Christmas; leading to a day of peace before they were forced to continue fighting. While there, they briefly missed meeting future companion Jack Harkness for the first time. (COMIC: The Forgotten)

The Doctor tried to take Rose home, but arrived a year late. To his surprise, a spaceship crashed into the Thames and finally alerted the world to the presence of aliens. He found the spaceship belonged to the Slitheen, who planned to reduce Earth to radioactive waste to sell as cheap fuel on the intergalactic market. Originally planning to go undercover, the Doctor was escorted by UNIT to 10 Downing Street to help deal with the worldwide catastrophe. Surviving the Slitheen's attempt to kill him, the Doctor became trapped in Downing Street with Rose and MP Harriet Jones, which forced him to ask Rose's mother Jackie and her boyfriend Mickey for assistance. At the cost of Downing Street, Mickey blew up the Slitheen with a Harpoon missile launched from the HMS Taurean. After instigating Harriet's reign as Prime Minister, the Doctor invited Mickey to join Rose and him in the TARDIS, but was refused. He gave Mickey a computer virus to wipe out all mentions of him on the internet. (TV: Aliens of London, World War Three) The Doctor and Rose investigated a spate of murders in 1966 London connected to the Lend-a-Hand Agency. They discovered the agency had been infiltrated by the Kustollons, who would invade Earth in the 31st century, instigating a war that would have resulted in the destruction of both humans and Kustollons. The Doctor foiled their plot to destroy the Moon, which would avert the 31st century war. During this adventure, the Doctor witnessed his old companions, Ben Jackson and Polly Wright, get engaged, although he didn't reveal his identity to them. (COMIC: The Love Invasion)

Their next trip brought the Doctor and Rose to Justicia in 2501. There, he 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) On a return trip to the Powell Estate, the Doctor helped defeat 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)

Tracking a distress signal, the Doctor went to the Vault in Utah in 2012. To his horror, he found a lone Dalek had survived the Time War and was being kept amongst other alien artefacts by Henry van Statten. Still haunted by his actions in the war and consumed with hatred towards his oldest foes, the Doctor delighted in electrocuting the Dalek, refusing to stop when it begged for his pity. To the Doctor's shock, the Dalek's personality changed after absorbing Rose's DNA and residual time vortex radiation. However, that did not stop it from slaughtering everyone inside the Vault. Preparing to kill his oldest enemy once and for all, the Doctor witnessed the Dalek commit suicide, leaving him the only survivor of a war that had taken billions. Feeling more alone, the Doctor gained a new companion in one of the Vault's employees, Adam Mitchell, at Rose's request. Henry's memory was wiped by his staff as punishment for the deaths caused by his refusal to kill the Dalek. (TV: Dalek)

On Adam's first trip, the Doctor took his two companions to the Fourth Great and Bountiful Human Empire to see the human race at its zenith. However, he found it no better than the 21st century, something that confused him along with the absence of aliens. The Doctor's investigation lead him to find a Jagrafess called Max was manipulating the information distributed by Satellite Five to control humanity, even having them develop backwards technology to assist in this matter. Thanks to one of the workers who learned the truth, Max was destroyed when the satellite's heat was rerouted to his control room.

Upon finding out Adam was trying to learn about the future of the 21st century's technology for his own gain, the Doctor "evicted" him from his TARDIS travels 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 un-merciful told him to live a quiet life to avoid having the implant discovered; scientists would dissect Adam to learn about the implant. (TV: The Long Game)

Taking Rose home once again, the Doctor saved the Powell Estate from Zargath and his invasion force. (COMIC: Death to the Doctor!)

The Doctor next took Rose to the grand opening of the Oriel, a transdimensional art gallery in the 37th century, only to find that everyone in the gallery had been enslaved by an artist called Cazkelf. Cazkelf sent a psychic distress signal to his species. The signal was diverted. The Doctor took Cazkelf to his homeworld, which had been devastated by a disaster. After this, the Doctor convinced Cazkelf to go on the straight and narrow, putting him in charge of the Oriel so that he could make the gallery a success. (COMIC: Art Attack)

Soon after, the Doctor was asked to be a representative for an alien planet that reminded him of Gallifrey, his lost homeworld. Haunted by the loss of his home and the Time Lords, the Doctor declined, until Rose persuaded him to reconsider. However, the Doctor soon discovered the planet's "spokesperson", Akimus Makassar, had set him up and was planning to take over his, and the other visiting representatives', minds. The Doctor placed him 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. The projection stole a Unit's mask and placed it over Makassar, trapping him in a mental feedback. (PROSE: The Masks of Makassar)

At Rose's request, the Doctor took her to the Powell Estate in 1987, when Pete Tyler, her father, died so she could be there for him. However, she saved her father from his hit-and-run death. Rose's actions caused the TARDIS to be thrown off into the time vortex. Enraged by her actions, he soon learnt that she had only agreed to travel with him to save her father and considered abandoning her in the past. After being attacked by a creature from outside time, the Doctor reconciled with Rose and the pair, along with a younger Jackie and a wedding party, took refuge in a church, whilst the creatures began consuming the Earth. He started working on a way to repair the damage to the universe while leaving Pete alive for Rose. However, after Pete accidentally made Rose hold her infant self, the Doctor sacrificed himself to the creature brought by the paradox. 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)

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. Inside, the Doctor overheard the 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 programme. The Doctor repaired the ship and he and Rose returned to the TARDIS on Earth. (PROSE: Doctor vs Doctor)

The Doctor and Rose travelled to a Vandosian ship, saving "a loser" called 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". (COMIC: Mr Nobody)

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

Returning to 2006 London, the Doctor and Rose encountered two Shadeys from another dimension and stopped them from manipulating playwrighter Robert Greene to assassinate William Shakespeare in 1592. Going back in time to protect the famous playwright, the Doctor briefly took over his position on stage. (COMIC: A Groatsworth of Wit)

He next took Rose on a cruise on 22nd century Mars, where they attended the wedding of rich galactic businessman, Alvar Chambers and his eighth wife. When the Doctor fell into the Martian sea, he encountered an entity that killed people by feeding on their worst fears. However, the entity had "swallowed up" too many people and self-destructed. (COMIC: The Cruel Sea)

Travels with Rose and Captain Jack
The Doctor tracked a Chula ambulance to 1941 London and met a galactic conman called Jack Harkness, a 51st century ex-Time Agent who mistook them for members of the Time Agency. Distrustful of Jack, the Doctor soon learned that a child in a gasmask had been killed and was half-way resurrected by the nanogenes inside the ambulance. The nanogenes had not seen a human before; they took the gasmask for the child's face and fused it to him, spreading to other people who touched him, also transforming them into gasmask zombies. The Doctor fixed the nanogenes' mistakes by comparing the DNA of the child and his mother Nancy, restoring the infected zombies to normal. The Doctor rescued Jack from his Chula warship just before it exploded, taking him aboard the TARDIS as his latest companion. (TV: The Empty Child / The Doctor Dances)

The TARDIS materialised on an abandoned Soviet naval base. There, the Doctor, Jack and Rose were hunted by something that predated even the stone circle on the cliff top. (PROSE: The Deviant Strain)

They next landed in Bromley in 2005. There, the Doctor encountered a genius named Chantal Osterberg, who wished to wipe out humanity for mindlessly using packs to control their emotions. He was forced to stop her from carrying out this plan. (PROSE: Only Human)

When the TARDIS became powerless to travel through time, the Doctor went to Cardiff so that the TARDIS could refuel via the Cardiff Space-Time Rift that was opened in 1869. Whilst in Cardiff, the Doctor and his two companions, joined by Mickey, captured Blon, the sole Slitheen survivor of the attack on Downing Street. 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 trial for her family's crimes. The Doctor confiscated her extrapolator to use as a "power-booster" on the TARDIS and took her to a resturant for dinner as her last request. After he remained unmerciful towards her, Blon tried to tear the TARDIS - and the Earth apart in an attempt to escape on the extrapolator. However, the damaged 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 stoppd off at a colony world, where the locals had become confused, believing that fiction was true. He undid the mind control the chips they ate to suppress. The Doctor also returned the books to them, the books having been previously banned. (PROSE: The Stealers of Dreams)

The Battle of the Game Station
After having an adventure in Kyoto, Japan, the Doctor, Rose and Jack were teleported to Satellite 5 a hundred years after their last visit, only to be put in deadly versions of TV game shows. After escaping Big Brother alongside a contestant called Lynda Moss, whose request to travel with him he accepted, 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 was arrested for breaking in and out of the games. However, he and Jack physically overpowered the guards and set off to stop the deadly "entertainment".

Taking "hostages" in the control room, the Doctor found his 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 was horrified to find two hundred Dalek battleships. Establishing contact, the Doctor learned his old foes had taken Rose hostage, but promised the Daleks that he would rescue her and destroy them for the final time. (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. Devastated at the thought of the Time Lords perishing for nothing, the Doctor knew his fight against the Daleks was suicidal and sent a reluctant Rose back to the 21st century in the TARDIS while Jack and he prepared for the inevitable extermination whilst also gathering a possible resistance consisting of gameshow contestants and operatives. He 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: the resistance were all killed, including Lynda Moss and Jack.

When it came time to choose whether he would destroy his greatest enemies once and for all or let the population on Earth be killed out of an act of cowardice, the Doctor proudly told the Emperor that he would choose to be a coward rather than killer. Much to the Doctor's surprise, in the 21st century, Rose opened the heart of the TARDIS and looked upon it; she became the powerful Bad Wolf entity, which had been following the Doctor ever since his first meeting with Rose. 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 Emperors atoms into dust, ending the Time War. (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 kissed her, drawing the time vortex from her body and into his before sending it back into the Heart of the TARDIS. (TV: The Parting of the Ways)

Taking an unconcious Rose, he left in the TARDIS, abandoning Jack on the deserted Game Station, whom Rose had converted into an immortal fixed point in time with her Bad Wolf powers; the Doctor, as a Time Lord, could not stand being around someone "wrong". (TV: The Parting of the Ways, Utopia) Knowing that his brief possession of the vortex energy had caused cellular damage to his body, the Doctor told Rose about wanting to take her to a new location, but not as himself now, trying his best to explain regeneration. When regeneration energy briefly spiked, he warned Rose away from him for her own safety. Before "going", the Doctor told Rose she had been absolutely fantastic - "And you know what? So was I!" - before regenerating into his next incarnation. (TV: The Parting of the Ways)

Undated adventures

 * River Song met the Ninth Doctor. She apparently learned fairly quickly not to mention the Time War around him. She later wiped his memory with mnemosine recall-wipe vapour to keep the timeline intact. (GAME: The Eternity Clock)

Personality
This incarnation of the Doctor was deeply affected by his actions in the Last Great Time War. He hid his sorrow with a facade of manic energy and a sharp, offbeat wit. Nevertheless the weight of destroying the Time Lords and the Daleks preyed upon him, creating an emotional incarnation of great sorrow and anger. This incarnation was sometimes emotionally exhausted and would break down when faced with pain, suffering, or death. This once resulted in a moment of joy and relief when he realised that he could, for once, reverse the pain and suffering he had encountered, whooping, "Just this once - everybody lives!!" (TV: The Doctor Dances) He possessed a new appreciation for the wonders of the universe and more keenly than ever burned with a desire to keep the universe safe from harm. Despite this, this incarnation of the Doctor was more adept at noticing the flaws of humanity than any of his predecessors.

When asked by the Emperor of the Daleks whether he was a coward or a killer 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 he couldn't bring himself to destroy the Earth even to rid the universe of the Daleks, and proclaimed himself a coward. In doing so however, 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. That Dalek had even stated he would have made a good Dalek himself. (TV: Dalek, The Parting of the Ways)

While his previous incarnations were rarely heard uttering curse words, the ninth incarnation tended to use minor curses more freely. He was also more violent, physically coming into contact with guards when arrested although it should be noted he thought Rose had been murdered which probably influenced his actions. (TV: Bad Wolf)

The Doctor cared very deeply about Rose and was willing to let a lethal Dalek loose on Earth to keep her safe. (TV: Dalek) He was also reluctant to use a missile to destroy the Slitheen because he feared he would kill Rose too. (TV: World War Three) When the Daleks invaded Satellite Five, the Doctor lied to Rose about being able to use the TARDIS to stop them and sent her back home to protect her. He 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)

Habits and quirks
The ninth incarnation spoke with a distinctive Northern English accent. When Rose questioned this, he replied that "lots of planets have a North." He was critical of his own large ears. (TV: Rose) He had a fondness for saying "fantastic", with emphasis on the second syllable, whenever he saw something of interest or especially dangerous. (TV:  Rose, The End of the World, The Unquiet Dead, Dalek)

This incarnation called Mickey Smith "Mickey the idiot", or "Ricky". He called humans "stupid apes", seeing himself above them, often calling them this when angered by their actions. He rarely spoke of his past to others. He did not "do domestic", as he put it, which led to tension in his interactions with Jackie Tyler. (TV: World War Three)

He had a fondness for bananas. (TV: The Doctor Dances)

He often made dry jokes to those around him to diffuse tension, but usually ended up failing; on one occasion, it was a cynical joke. (TV: Rose, The Unquiet Dead, Aliens of London, World War Three, The Long Game, The Empty Child, The Doctor Dances, Boom Town, The Parting of the Ways)

He often gave speeches about things or lectured those he wished to scold. (TV: Rose, The Unquiet Dead, Aliens of London, Dalek, The Long Game, Father's Day, The Empty Child, The Doctor Dances, Boom Town, Bad Wolf, The Parting of the Ways)

Despite being bad at card tricks, he was a good pickpocket; he swapped Jack's sonic blaster with a banana. (TV: The Doctor Dances)

This Doctor had a tendency to say "what the hell" and often used "oi" to get people's attention. (TV: The End of the World, World War Three)

The Ninth Doctor had a habit of folding his arms and frowning when lecturing or listening intently. He would also grin when happy or when he found something funny. He was overconfident about his plans, even if he didn't think they would work. (TV: Rose et al)

This incarnation enjoyed, and was particularly skilled at, video games. (PROSE: Winner Takes All)

This incarnation wore a wrist watch, unlike previous incarnations and often referred to it to find out dates and years. (TV: The End of the World, Aliens of London, Dalek, The Long Game, Father's Day, The Empty Child, The Doctor Dances, Boom Town, Bad Wolf, The Parting of the Ways)

Skills and abilities
This incarnation of the Doctor could be quite violent and sometimes got into physical combat, being able to throw a guard against the wall whilst breaking out of prison. (TV: Bad Wolf) Although he has never been seen firing one, the Doctor has also been seen holding guns on at least two occasions. Unlike his companion Jack Harkness who usually used rather small guns, the Doctor was seen wielding fairly large ones. (TV: Dalek, Bad Wolf)

The Doctor also showed the ability to suck the power of the Time Vortex out of Rose Tyler with a kiss, saving her life at the cost of forcing him to regenerate. (TV: The Parting of the Ways)

The Doctor was skilled at video games. (PROSE: Winner Takes All)

Appearance
In stark contrast to the extravagant dress of most of his predecessors, the ninth incarnation wore a plain leather jacket, identified in World War II as that worn by a German U-boat captain by Jack Harkness. (TV: The Empty Child) He wore a plain red, green, navy blue, or black jumper, which Charles Dickens thought made him look like a navvy, (TV: The Unquiet Dead) dark trousers and a black, strapped wristwatch, in contrast to his previous incarnations, who preferred fob watches.

At one time, he was photographed wearing clothes reminiscent of those worn by his eighth incarnation. (TV: Rose)

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

He wore his hair close-cropped, unlike many of his previous incarnations who had had longer hair. He had large ears and he considered his nose large as well. He claimed they enhanced their respective senses. (TV: The Empty Child)

Casting
Originally, Russell T Davies approached Hugh Grant, who previously played the Doctor's alternate twelfth incarnation, to play the Ninth Doctor. He turned down the role, thinking the show would not take off. He expressed deep regret 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, 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].

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".

Other matters

 * With the total sum of TV, novels, comics and other media, the Ninth Doctor stands out as having, as of 2013, the shortest era of any Doctor.
 * The Ninth Doctor is only one of two incarnations to date to have the same companion throughout 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. In spin-off fiction, the only ninth incarnation story to date where he is not depicted travelling with Rose is the 2006 annual short story What I Did on My Christmas Holidays by Sally Sparrow.
 * The ninth incarnation was also the first never to face another Time Lord as an opponent on screen.
 * 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.
 * In the Japanese dubbing of the show, the Ninth Doctor is played by Katsuyuki Konishi.
