Ninth Doctor

The Ninth Doctor was the direct survivor of the Last Great Time War, but 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 crossly to those who rubbed him the wrong way. Despite this, he remained jovial and quite friendly towards anyone he took a liking to, slowly reasserting himself as the Doctor while letting go of his lingering wartime persona.

Rose Tyler was his most constant companion, although he did share several adventures with Jack Harkness as well. 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, 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 in a sacrifice to defeat.

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.

A day to come
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
This incarnation was born at the end of the Last Great Time War, when his predecessor's physical age had advanced well into that of an old man. As his body was "wearing a bit thin", his regenerative processes initiated automatically. Due to the timelines being "out of synch" from the presence of his future selves, (TV: The Day of the Doctor) the new Doctor was left to think he had brought forth the death of billions of innocent Time Lords, (TV: The End of the World) after being "born in battle". (TV: Journey's End)

Meeting Rose Tyler
Shortly after regenerating, and still "not quite calibrated" to his latest body, the TARDIS sensed a temporal problem in 2005 London and alerted the Doctor to the presence of the Nestene Consciousness. (PROSE: The Beast of Babylon) While tracking down the Nestene, the Doctor found a chief electrical officer murdered in the London shop, Henrik's. Continuing his investigation, he found a horde of Autons surrounding Rose Tyler, a young employee of the shop. He pulled her away from them, also warning her 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 given Rose to the Powell Estate, where Rose lived. After saving her from its attack, that was meant for him, the Doctor took it to his TARDIS, telling Rose 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 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. 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 noted that Mickey was not invited due to his apparent cowardice. Rose rejected his offer, and he dematerialised the TARDIS. (TV: Rose)

Solo adventures
Travelling alone, the Doctor picked up a distress call from the Godspeed and joined forces with crewmember Locklear to stop space barnacles from killing the crew. (PROSE: The Hungry Night)

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 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)

Landing in a garden shed in Devon on Christmas Eve 1985, the TARDIS "burped", jumping forward in time twenty years. 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)

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. The Doctor 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 was persuded to 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 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 allied with Charles Dickens 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. After this, 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 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)

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, had 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 three inside but saving them from the Slitheen. The Doctor contacted Mickey, telling him to 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 Rose and him in the TARDIS, but Mickey declined, unable to handle the dangerous life led by the Doctor. (TV: 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. (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. 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)

The companion who couldn't
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 artifacts, 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 defenses, 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)

For 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. 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 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, but his 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)

He next took Rose on a cruise on 22nd century Mars, where they attended the wedding of plutocrat Alvar Chambers to his eighth wife. As the Doctor fell into the Martian sea, he encountered an entity that killed people by feeding on their worst fears, putting them into a state where their identities would dissolve within him while they were dreaming. The entity stole his body and began to torment Rose with a nightmare of a villainous Doctor coming back too late in Rose's life for her to be a companion and then sending it spiraling into ruins to spite her. Rose saw through this illusion and found the real Doctor trapped within the entity, tasking her with freeing his victims while he dealt with the actual creature. (COMIC: The Cruel Sea) Taking Rose home once again, the Doctor saved the Powell Estate from Zargath and his invasion force. (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)

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)

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 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, which stole a Unit's mask and placed it over Makassar, trapping him in a mental feedback. (PROSE: The Masks of Makassar)

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)

Returning to 2006 London, the Doctor and Rose encountered two Shadeys from another dimension and stopped them from manipulating dying playwright 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. In return for relinquishing the power of the Shadeys, the Doctor and Rose promised to remember Greene, and he sacrificed himself to repel the Shadeys. 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)

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 immediate successors, who were also planning to eat at the café looked on. (COMIC: Four Doctors)

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 die 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 known incarnation up to his final incarnation, save his concealed wartime incarnation.

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: Prisoners of Time)

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)

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)

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 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 against struggling with the age-regression gun before the effects wore off and the Tenth Doctor re-emerged. (COMIC: The Fountains of Forever)

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)

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, with the Tenth and Twelfth Doctors musing that he was unable to find a timeline in which the Ninth Doctor was "anything less than fantastic." (COMIC: Four Doctors)

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) He hid his sorrow with a façade of manic energy, sharp, offbeat wit and enthusiastic confidence, but would 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)

When he realised that he could reverse the pain and suffering he had encountered with the Empty Child plague, the Doctor became overjoyed, whooping that, "just this once - everybody lives", 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)

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)

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 to 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 held a commanding presence, being able to take command 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)

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", (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)

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 bananas, calling them a "good source of potassium". (TV: The Doctor Dances)

He was overconfident about his plans, even if he didn't think they would work. (TV: Rose) 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)

Despite his more celibate nature, (TV: Rose, The End of the World) the Doctor cared very deeply about his companion 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) 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. (TV: Dalek)

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) The Tenth Doctor, likewise, held a low opinion of his immediate predecessor, considering him to be violent due to being "born in battle". (TV: Journey's End) The Twelfth Doctor, however, claimed 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. (COMIC: Four Doctors)

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) 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)

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: The Long Game) 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)

Skills and abilities
The Ninth Doctor could be quite violent, (TV: Dalek) and sometimes got into physical combat, being able to wrestle the head off an Auton copy of Mickey Smith, (TV: Rose) hold his own against Idris Hopper, (TV: Boom Town) and throw a guard against a wall whilst breaking out of prison. (TV: Bad Wolf) 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)

The Doctor 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)

The Doctor could slow down his perception of time just by concentrating on it, being able to pass through spinning blades with his eyes shut as a result. (TV: The End of the World) He 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)

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)

Appearance
The Ninth Doctor had pale blue eyes and was rather tall. He had 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 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 though 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)

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
The Ninth Doctor primarily wore a plain leather jacket, (TV: Rose) compared by Jack Harkness to that worn by German U-boat captains, (TV: The Empty Child) along with a number of v-neck jumpers, coming in plain maroon, (TV: Rose) navy blue, (TV: The Unquiet Dead) military green, (TV: Dalek) dark purple, (TV: The Empty Child) and plain black. (TV: Bad Wolf) Completing the ensemble were dark trousers, a pair of black leather boots, 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)

Both Charles Dickens and Honoré Lechasseur compared the Doctor to a navvie. (TV: The Unquiet Dead; PROSE: The Albino's Dancer)

Other clothes
Whilst at the launch of the RMS Titanic in 1912, the Doctor was photographed wearing clothes reminiscent of those worn by his eighth incarnation. He was also discovered wearing a navy blue polo-neck jumper rather than a V-neck jumper in a photograph of the John F. Kennedy assassination. (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)

During his brief resurrection resulting from an age-regression gun, the Doctor wore his successor's blue pinstripe suit and trench coat. (COMIC: The Fountains of Forever)

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, 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

 * 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, the only ninth incarnation stories to date where he is not depicted travelling with Rose are the 2006 annual short story What I Did on My Christmas Holidays by Sally Sparrow and the Puffin eshort The Beast of Babylon.
 * 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 incarnation was also 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 the Master in Prisoners of Time, 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.
 * In the Japanese dubbing of the show, the Ninth Doctor is played by Katsuyuki Konishi.
 * Assuming his predecessor's recollection of age was correct, the Ninth Doctor began his life around 800 years old (TV: The Day of The Doctor). Considering the fact that he had adventures on his own when Rose initially declined his offer to travel with him, and he gave his age as 900 following the point he accepted Rose as a companion (TV: Aliens of London, The Empty Child), this suggests he travelled alone for about a century.
 * 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 Eccelston 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:

"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."
