Fifth Doctor

Youthful in mind, manner and appearance, the Fifth Doctor expressed an interest in all things Victorian and Edwardian: cricket, tea, fair play, good manners, and a keen interest in science and exploration.

He was also a sensitive and profusely humane incarnation of the Doctor, who did not make himself an imposition, preferring to be honest, reserved, and honourable. However, the Doctor was also less willing to do what he thought was immoral, and became highly conflicted about what choices he could make in a crisis that were truly right. His hesitancy made him seemingly more fallible than many other incarnations, making those around him wonder if he was capable of resolving difficult situations. Nevertheless, he was one of the most overtly fearless incarnations, and frequently found himself right in the thick of battle.

Like his first two incarnations, the Doctor often travelled with multiple companions. However, his TARDIS was rarely as harmonious as those of his predecessors. Instead, he frequently found himself stuck between Tegan Jovanka's pessimism and Adric's arrogance or Turlough's antagonism. Stuck in the middle with him was usually Nyssa, who regularly had to stand as a voice of reason. Even after he seemingly was settled on just having one companion, he and Peri Brown found another companion, a pharaoh from Egypt called Erimem, and the Doctor once again slid into the role of the oft-maligned chaperone.

During his final adventure, the Doctor accidentally exposed himself and Peri to unrefined spectrox, contracting fatal spectrox toxaemia. Though he acquired an antidote, the Doctor had only enough for one person; he gave it to Peri. Not knowing if the disease could kill Time Lords for good, the Doctor gambled on regeneration saving his life, successfully regenerating into a new body after experiencing a vision of the Master and his former companions.

A day to come
The First Doctor would occasionally have premonitions of his future incarnations, (PROSE: A Big Hand for the Doctor) and there was a rumour that he was able to glimpse his first seven regenerations during a game of Eighth Man Bound. (PROSE: Christmas on a Rational Planet, Lungbarrow) He once indicated he knew a future incarnation would enjoy cricket. (COMIC: A Religious Experience)

When the First Doctor learned that he was diverted from the South Pole by "forces from the future" to stop him from becoming an incarnation that would play a key role in a future conflict, he was informed by the Player that he would have "lots of new faces" before he regenerated into the incarnation involved in the conflict. (AUDIO: The Plague of Dreams)

The First Doctor was shown footage of the Fifth Doctor, as well as his ten other successors, by the Testimony when he expressed doubt over the Twelfth Doctor's identity. (TV: Twice Upon a Time)

When the history of Atkya changed, the Second Doctor discovered that one of his future incarnations had accidentally doomed the Atkyans when a stabilising agent to a cure he made for renepscia syndrome caused the metabolism of the Atkyans to speed up. (PROSE: One Step Forward, Two Steps Back)

While trying on new outfits after his third regeneration, the Fourth Doctor was worried he had regenerated again when he misunderstood Alistair Gordon Lethbridge-Stewart's comment about him having "changed". (TV: Robot)

After receiving a summons from Gallifrey, and telling Sarah Jane Smith that he had to leave her behind to answer it, Sarah Jane asked to Doctor if the summons meant he would regenerate again, to which he voiced his own uncertainty. (TV: The Hand of Fear)

During a reunion with Mike Yates in the early 21st century, the Fourth Doctor learned he had "changed, and changed again," when Yates commented on him being "back as [he] [was] in the seventies", despite hearing about the Doctor regenerating. (AUDIO: The Stuff of Nightmares)

After crashing the TARDIS on the way to Shada, the Fourth Doctor briefly believed he had regenerated. (PROSE: Doctor Who and the Krikkitmen)

After seeing the Watcher in a dream, the Fourth Doctor thought of his next incarnation. (PROSE: Into the Silent Land)

Post-regeneration
After being severely injured from falling off the Pharos Project Radio Telescope, the Fourth Doctor merged with the Watcher and regenerated into his fifth incarnation. (TV: Logopolis) The regeneration proved to be a difficult one, nearly failing. His companions took him to the Zero Room to stabilise. While he was recovering (TV: Castrovalva) and entering into a hallucination, (PROSE: The Comet's Tail) a message came from Adric, whom had abducted, saying the TARDIS was heading for Event One. The Doctor left Tegan and Nyssa instructions on how to escape by jettisoning rooms from the TARDIS.

Much of the Zero Room was jettisoned as a result and the Doctor, needing a peaceful place to continue his stabilisation, went to Castrovalva. After he had recovered, he learned the city was artificial, created by block transfer computations. The Master, in the guise of the Portreeve, had created the city with Adric's mind. The Doctor rescued Adric and the TARDIS crew fled Castrovalva as it collapsed in on itself, leaving the Master to be erased from existence with it. (TV: Castrovalva)

Early adventures
The Doctor and his companions visited what appeared to be a planet inhabited by highly unusual people, but eventually realised that they were on the Psychodrome, where their memories, desires and fears were being brought to life. One of their creations, Nyssa's twisted perception of the Doctor, mixed with her own thoughts on her lost father and the Master, named King Magus, who planned to use the memories of the TARDIS crew to conquer his world, but they managed to escape. (AUDIO: Psychodrome)

Visiting a colony in the 28th century to replace what had been jettisoned from the TARDIS, the Doctor was thrown in front of a train by Roz Forrester in order to stall the train. After joining a scientific mission, the Doctor encountered his seventh incarnation, and the two fought the misguided Ferutu together. (PROSE: Cold Fusion) Afterwards, the Doctor and his companions spent Christmas with Iris Wildthyme. (AUDIO: Excelis Dawns)

When Nyssa discovered the TARDIS was running low on food, the Doctor took the TARDIS to a supermarket to restock. However, had set up a trap at the supermarket by turning it into a maze, but the Doctor was able to lead Adric, Nyssa and Tegan out of the maze by marking their trail with frozen peas. (PROSE: Dr. Fifth)

The Doctor visited the planet Isopterus, which he found to be overrun by giant termites. He freed the surviving humanoid inhabitants held captive in the termites' nests and took them to freedom on a safe planet. (COMIC: On the Planet Isopterus)

The Doctor was next reunited with his old friend, Edward Grainger, who had a new-born baby boy. Adric was taken over by a complex computer entity, attacking the Doctor, Tegan and Nyssa and kidnapping Edward's son to create a new body for itself. The Doctor uploaded the computer entity into the TARDIS systems and transported it to Otho, the second moon of Liberius, blocking its control over Adric and Edward's son. (PROSE: First Born)

Attempts to return to Heathrow
Setting off for more adventures, the Doctor was asked by Tegan to return her to 1981 London, as she had only entered his company by accident. The Doctor got the TARDIS to 1981, but in the wrong place: Monarch's spaceship. The TARDIS crew stopped Monarch's scheme for time travel with cyborgs, even though the Doctor had to deal with Adric, who had allied himself with Monarch. Afterwards, Nyssa, who was greatly weakened after almost being converted into a cyborg, collapsed. (TV: Four to Doomsday)

While Nyssa rested in the TARDIS, the Doctor, Adric and Tegan visited the planet Deva Loka. While Tegan slept in a peaceful location, the Doctor and Adric were arrested by Commander Sanders, who was undergoing a nervous breakdown. With an artefact known as the Box of Jhana provided by the Kinda, Deva Loka's natural inhabitants, they managed to restore his mind. The Doctor then discovered that a malevolent entity known as the Mara had used Tegan to possess a male from the Kinda tribe. Using mirrors, the Doctor was able to force the Mara out, leaving it to perish. He then helped with asking the exploration team to leave Deva Loka. (TV: Kinda)

Another attempt to return Tegan home saw the Doctor land his TARDIS at Heathrow in 1666. The locals accused the Doctor of carrying the plague and hunted him and his friends down, until they were saved by Richard Mace. Allied with Mace, the Doctor and his companions found the Terileptils were enhancing the plague in carrier rats to rid the planet of humans so they could take over. In stopping them, the Doctor had his sonic screwdriver destroyed and accidentally caused the Great Fire of London. (TV: The Visitation) The Doctor decided not to replace his sonic screwdriver, despite its usefulness. (TV: Snakedance)

After experiencing a strange dream, the Doctor found that the TARDIS had materialised on a space station orbiting the planet Dymok, which he soon learned had been created by the Celestial Toymaker to help him find a replacement host for him, now that Rallon was dying. Although the Toymaker attempted to sow discord between the Doctor and his companions, they rallied themselves in time to help the Dymova disrupt the Toymaker's link with Rallon, allowing Rallon to expel the Toymaker from his body by triggering all twelve of his regenerations at once. The Toymaker was subsequently delayed when Rallon's Watcher merged with the Toymaker to keep him in check in the future. (PROSE: Divided Loyalties)

The Doctor visited eastern Europe in the early 11th century, where he tried to help the people of Udilf's town defend themselves against Czar U'thai's forces. The Doctor disapproved of Adric introducing the longbow to Udilf's people, knowing how many deaths the weapon would cause in the future. (PROSE: The Immortals)

Hearing alarms warning about spatial anomalies, the Doctor rushed to a room in a distant corner of the TARDIS without explaining to Adric and Tegan what was going on. There, they found Nyssa lying on the floor with a jewel. Once Nyssa awakened, the Doctor explained that the jewel was a communication node that the Master had given to Susan Foreman, and the Master, during the old days on Gallifrey, had tried using the node to telepathically contact Nyssa to find where the Doctor was. The Doctor explained that the node was hidden among other volatile bits and pieces in that TARDIS room so that the Master and the Time Lords couldn't follow the First Doctor and Susan. (AUDIO: The Toy)

Still trying to get Tegan home, the Doctor answered a psionic distress call from Harry Houdini, who needed his help to stop a fortune teller in 1920s England. However, he found Houdini had been manipulated by the Master, who tried to have the Doctor and his friends killed. But the Doctor managed to stop his revenge plan. Whilst there, he was contacted by his eleventh incarnation, who needed him to return an Ovid sphere to its race. (AUDIO: Smoke and Mirrors)

Final adventures with Adric
On a trip to Oxfordshire on 11 June 1925, the Doctor was mistaken for a cricket player summoned by Lord Charles Cranleigh. Helping Charles win a match, the Doctor and his friends were invited to a fancy-dress ball to celebrate, (TV: Black Orchid) where the Doctor partook in another game, only for the ball to be stolen by Ace. (COMIC: Time & Time Again) The Doctor's costume was stolen and used as a disguise during a murder, which led to the Doctor being framed by Lady Cranleigh for the crime. The Doctor cleared his name by revealing the TARDIS, and uncovering a Cranleigh family secret: Charles's supposedly deceased brother, George, who had been mentally and physically scarred by natives during a trip to find a rare flower, was the culprit. George kidnapped Nyssa, who was identical to his ex-fiancée, Ann, but the Doctor and Charles saved her. Unfortunately, George fell off the roof to his death when Charles moved in to hug his brother. (TV: Black Orchid)

The Doctor tried to replenish the TARDIS with artron energy, but instead arrived in the middle of a battle between the Rutans and the Sontarans. He, Adric, Nyssa and Tegan were captured by the Rutans and escaped, only to be captured by the Sontarans in turn. After the Doctor looked over their tactical position and discovered that they were doomed, the Sontarans returned him and his companions to the TARDIS, where the Doctor witnessed Adric, Nyssa and Tegan being abducted by Adam Mitchell, and realised that Adam had been in his past before. (COMIC: In Their Nature)

Following a chronal trail left by the Eleventh Doctor as the Tenth Doctor merged their TARDISes together, the Fifth Doctor joined his other incarnations as they stormed Adam's fortress in Limbo to save their friends from Adam and. Though the Master attacked them with Autons, Frobisher was able to free the captured companions, and they helped the Doctors fight off the Autons, as Adam had a change of heart when the Master revealed he intended to use the chronal energies he had stolen across the Doctor's timelines to destroy the universe. After the Master killed Adam as he foiled his plans, the eleven Doctors honoured Adam as a "true companion". (COMIC: Endgame)

While Tegan and Nyssa went on a trip together, the Doctor took Adric to Vaga, a planet which he had visited before. Whilst there, they saved a populated Vagan spacecraft from a Pyron space-shark. (PROSE: The Key of Vaga) The Doctor and Adric visited Ixos-4, a planet of which he had heard some interesting stories. Whilst there, they helped rescue a pair of earwig-like aliens who had crash-landed there some years earlier. (PROSE: Planet of Fear)

When the Fourth Doctor used his TARDIS tuner to begin a temporal meta-collision with his other incarnations, the Fifth Doctor learnt that Earth was under threat from a pandimensional entity that had trapped his fourth incarnation in his TARDIS. While the Fifth Doctor argued with his other incarnations, the War Doctor used encoded messages from the Sixth Doctor to stop the invasion before it began, and the Sixth Doctor installed a way to expel the entity from the Fourth Doctor's TARDIS. With the crisis over, the Fifth Doctor went off to have his dinner. (WC: Doctors Assemble!)

When the TARDIS landed on Lemaria, the Doctor, Adric, Tegan and Nyssa found they had arrived on Freedom Day; a celebration of when the First Doctor and Susan Foreman freed the Lemarian people from the Megrati. Attending a play that was a re-enactment of the liberation, the Doctor noticed that the actor playing his first incarnation was a future incarnation, and then bore witness to his future self bluffing the Megrati into a retreat when they attempted a second invasion. (PROSE: The Constant Doctor)

When the TARDIS refused to land in a place with a dimensional anomaly, the Doctor went outside and found a damaged spaceship and encountered the Dar Traders, who claimed that the travellers were dead. The Doctor was stabbed by an assassin, but Nyssa helped him by transferring the energies from her Trakenite body and calcified the assassin. (AUDIO: The Darkening Eye)

When Adric's attempt to pilot the TARDIS caused the ship to land on Fleming's Island, the Doctor and his companions were forced to investigate the mystery of a vanished cult, which led to the discovery that the Cult had found a species of life-form that were essentially sentient numbers, represented as the I, the most impossible number in mathematics. Realising that the cult's actions had drawn in the I Predator and made it aware of N-Space, the Doctor and his companions destroyed the computers that had been used to trap the I and retreated to the TARDIS, cutting the I and its ilk off from existence. (AUDIO: Iterations of I)

After having a laugh with Tegan and Nyssa in the control room, (PROSE: The Boy Wonder) the Doctor took the TARDIS to an idyllic world, where he, Tegan and Nyssa spent the day relaxing, whilst Adric visited a glade filled with statues of countless races throughout the universe. He was tempted to transform into a statue, but the Doctor dragged him back to the TARDIS and the crew left the planet, leaving Adric resentful of the Doctor denying him the right to choose his own destiny. (PROSE: Hearts of Stone)

Adric became distant towards the Doctor, Nyssa and Tegan, causing him to request a return to E-Space, which the Doctor angrily denied out of fear that he would become trapped in the mini-universe again. Visiting Earth to cool off after their argument, the Doctor uncovered a plot by the Neomorph Cybermen to destroy Earth with a Cyber-bomb. After defusing it, he traced the Cybermen to Captain Briggs' space freighter, which they now plotted to use as a giant bomb.

As the freighter shifted through time to the distant past, Adric tried to stop the freighter by cracking logic codes on the ship's controls, but a surviving Cyberman destroyed the controls, causing the freighter to hit the Earth and kill the dinosaurs. Trapped on the freighter, Adric also died. Nyssa and Tegan were devastated, (TV: Earthshock) and the heartbroken Doctor was haunted by the fact that he couldn't use his ability as a time traveller to save him, as Adric's death was now fixed in Earth's history. Adric's death would haunt the Doctor for centuries, (COMIC: The Forgotten) and led him to swear that he would not allow another of his companions to die. (PROSE: Goth Opera)

Still recovering from losing Adric, the Doctor finally managed to return Tegan to Heathrow Airport in 1981, where they were recruited by C19 to investigate a missing Concorde. Taking a trip on another Concorde plane, they, along with the crew, were transported to 140,000,000 BC. They visited a Citadel populated by the previous Concorde passengers, where the Doctor encountered the Master, plotting to use the ancient Xeraphin gestalt as a power source for his TARDIS, which had been badly escaping Castrovalva. Stopping the Master from stealing parts of his own TARDIS, the Doctor abandoned him on Xeriphas to let the Xeraphins take their revenge.

After using his TARDIS to bring the Concorde back to 1981, the Doctor and Nyssa left without giving a farewell to Tegan and set off in the TARDIS once again. (TV: Time-Flight)

Lone travels with Nyssa
After a dimensional anomaly apparently resulted in the ghost of Adric appearing in the TARDIS, the Doctor tracked the accompanying dimensional anomaly to 1851, where Queen Victoria had just attended a séance performed by James Lees that put her in touch with her dead husband and told her of a door to the afterlife. The Doctor was able to convince Victoria to appoint him her scientific advisor and investigate the apparent door, learning that it was actually a dimensional anomaly to a world whose natives could assume the appearance of others. With the natives' impression of Earth coloured by the treatment "Lees" had received when he started having visions, the Doctor sealed the rift after rescuing the real Lees, the soldiers who had accompanied the Doctor sacrificing themselves to keep the natives back until the rift was closed. (PROSE: Empire of Death)

Travelling to Maine in 1945, the Doctor and Nyssa freed the Veritans that three Dipthodat had been selling while posing as the Acklin family. (PROSE: Tip of the Tongue)

Visiting an asteroid that he had saved years previously, the Doctor and Nyssa met Earth colony agent, Sebastian Musgrove, the lone survivor of the asteroid following a Dalek attack. They also discovered a dying creature called Telxzana. As her life force was the asteroid's sole continent, her death would result in the asteroid's destruction. Because of this, the Doctor contacted Earth to have Musgrove taken to safety, but not before watching the asteroid's last days. (PROSE: Lonely Days)

When Nyssa attempted to repair the TARDIS chameleon circuit, the TARDIS transformed into a whale and trapped the Doctor and Nyssa on an isolated island on Earth. The Doctor lured his ship onto the island. Having grown fond of the police box form, the Doctor made the TARDIS change back and ensured that the chameleon circuit would remain broke for the time being. (AUDIO: The Deep)

The Doctor took Nyssa to Alaska, where they found prehistoric Permian creatures waking from a long period of hibernation, as well as deformed hybrids wandering the ice fields. The Doctor was forced to destroy the Permians before they could spread over Earth, and claimed that the hybrids would soon die without the energies of the Permians to sustain them. (AUDIO: The Land of the Dead)

Something had caused Nyssa to be taken from the TARDIS. Tracking her to Switzerland in 1963, the Doctor discovered a set of Spillagers trying to manipulate Alison Speer and Peril Bellamy to allow them to invade. (AUDIO: Winter for the Adept)

After Nyssa repaired the proximity sensor on the TARDIS, the Doctor accidentally piloted the TARDIS into a time tunnel in the vortex. Landing in America during the 22nd century Dalek invasion, they were almost caught by the Daleks. Managing to escape, they got trapped in the time tunnel dragging them to the 42nd century where the Earth had been ravaged by the Mutant Phase. Learning that this was caused by mutagenic in a Dalek from the invasion, the Doctor went back with a set of Thal scientists to stop it, but discovered that the whole affair was caused by a time paradox created by accident by the Dalek Emperor. (AUDIO: The Mutant Phase)

The Doctor arrived at Traken before its destruction to find the cause of Nyssa's psychic sensitivity. They learned Kwundaar had caused her illness deliberately. (AUDIO: Primeval)

The Doctor was charged by the High Council with the task of reaching another renegade, Cardinal Zero, on the planet he retired to live among an avian species, and make sure he didn't accelerate their technological development. The Doctor ended up aiding Zero's regeneration into a hybrid between Time Lord and avian, thus making him definitely an exiled from Gallifrey, which allowed him to keep leading the species. (AUDIO: Spring)

Having landed on Mondas before it returned to the solar system, the Doctor at first tried to resist interfering but ultimately tried to warn the locals about what was happening relating to the creation of the Cybermen. His actions saw him arrested and his alien biology drew the attention of Doctorman Christine Allan, who used him as a template to improve the Cybermen who at this time were consistently failing. After Mondas fell victim to a cosmic storm, he helped the Mondasians destroy the Central Committee which had accelerated the conversion program in response. He and Nyssa hoped this may alter history somewhat, however Cyber Commander Zheng survived and restarted the program. (AUDIO: Spare Parts)

Causing a collision with a Koteem ship, the Doctor and Nyssa landed on Veln and discovered dyestrial poisoning in the atmosphere. The Doctor went to warn the locals, but Nyssa was arrested for murder. He broke her out of custody and discovered that the Koteem and Forleon were creating hybrids to prolong both their races. He left the planet not knowing that all their problems were because of the accident the Doctor caused. (AUDIO: Creatures of Beauty)

The Doctor and Nyssa also met P. G. Wodehouse, (AUDIO: Autumn) and fell afoul of Sir Isaac Newton and were arrested for having coins from Earth's future, mistaken for counterfeit. Sir Isaac was able to work out their true nature by himself, but this caused him to have a nervous breakdown. The Doctor stayed behind to help him and assured him his name would be remembered, at least until the 21st century. Grateful, Sir Isaac let him go. (AUDIO: Summer)

The Doctor set down in the English village, Stockbridge, to play cricket while Nyssa tried her hand at writing a novel. She caught the attention of a local boy, fell in love and contemplated life on Earth. However, she decided to continue travelling with the Doctor. (AUDIO: Autumn)

While Nyssa was undertaking a solo expedition in 13th century Rhodes, the Doctor travelled alone for a time. (AUDIO: Renaissance of the Daleks)

The Stockbridge ordeal
The Doctor travelled to Stockbridge to continue playing cricket. Meanwhile, Melanicus, having seized control of the Event Synthesizer from the Prime Mover, used it to wreak havoc on time.

While investigating the cause of the distortion, the Doctor met Sir Justin of Wells, who was plucked from a joust in his own time. Justin accompanied the Doctor to Gallifrey and the Althrace system to attend a meeting with the High Evolutionaries of Althrace who explained the situation.

Eventually, with the help of Rassilon, Merlin the Wise and Celestrial Intervention Agent Shayde, the Doctor confronted Melanicus, who had hidden the Event Synthesizer in a time-altered version of the local church. Justin, the Doctor and Shayde fought Melanicus, with Justin dealing the killing blow at the cost of his own life, restoring the universe to normal. (COMIC: The Tides of Time)

Continuing his Stockbridge visit, the Doctor met a UFO spotter called Maxwell Edison. When Maxwell stumbled into his TARDIS, the Doctor was taken to a ghost ship in Earth's orbit. But before he could investigate, the ship began breaking up. (COMIC: Stars Fell on Stockbridge)

After spending a few months living in Stockbridge, the Doctor discovered his TARDIS had been embedded in the limestone of the Stockbridge quarry. Investigating, the Doctor found himself in a forest on fire, which had been started by an Elemental Being. As he tried to escape, the Doctor learned the Elemental had possessed the TARDIS's computer, leaving him unable to control his ship. He was saved by Shayde and taken back to Gallifrey, where he stood trial as the Elemental had secretly been manipulating his TARDIS whilst he was living in Stockbridge. Shayde managed to clear him of any charges, but the Doctor remained curious over Shayde's true motives. (COMIC: The Stockbridge Horror)

While travelling in the TARDIS, the Doctor arrived on an island in the Pacific Ocean, where he met Fuji and Gus Goodman. The Doctor was forced to take Gus away from the island. (COMIC: Lunar Lagoon) The Doctor and Gus arrived in an alternative timeline where World War II hadn't finished, created by the interventions of and the Ice Warriors. The Doctor, however, managed to prevent this timeline coming to pass, and defeated the Ice Warriors and the Monk. (COMIC: 4-Dimensional Vistas)

The Doctor and Gus travelled to the planet Celeste, where the Doctor offended Josiah W. Dogbolter by refusing to sell the TARDIS to him, so Dogbolter sent a hitman named the Moderator after the Doctor. Just as the Doctor had dropped Gus off, the Moderator ambushed them and shot Gus. In the ensuing hail of gunfire, Gus shot and incapacitated the Moderator, but died from his wounds. In an emotional state, the Doctor picked up Gus' fallen pistol and used it to break the Moderator's pistol before dropping the Moderator off near a hospital. (COMIC: The Moderator)

Troubles with Thomas Brewster
The Doctor reunited with Nyssa and had an encounter with Daleks from an alternative timeline. (AUDIO: Renaissance of the Daleks)

The Doctor spent time in Victorian London, where Thomas Brewster stole the TARDIS. (AUDIO: The Haunting of Thomas Brewster) The Doctor and Nyssa then arrived on the land of the "Scorpion King", who they discovered was really their old friend Adric. Reconciled with the pair, Adric aided them in escaping the past and locating the TARDIS. (AUDIO: The Boy That Time Forgot) Putting right what Brewster had made wrong, (AUDIO: Time Reef) the Doctor and Nyssa bid him goodbye on Earth in 2008 with his lover, Connie Winter. (AUDIO: A Perfect World)

Further travels with Nyssa
In 1199, the Doctor and Nyssa found a Rutan inhabiting the Stockbridge Castle on Earth. They managed to defeat the Rutan, but were caught in an explosion. (AUDIO: Castle of Fear) They survived, and arrived in Stockbridge during the late 20th century, where the Doctor met Maxwell Edison again. (AUDIO: The Eternal Summer)

The Doctor and Nyssa were swept up by a time storm to Stockbridge, where a strange rain was mutating the villagers into Dalek slaves. The Daleks tried to turn the Doctor into a Dalek and use his TARDIS to help conquer the universe, but failed. (AUDIO: Plague of the Daleks)

Travelling to Concordum in the hope of getting to hear some of the last Traken music in the universe, the Doctor and Nyssa's visit was cut short when they uncovered a plot by a group of Entropy Sirens involving a musical piece entitled "White Waves, Soft Haze". (AUDIO: The Entropy Composition)

On a planet where the Doctor used his "John Smith" alias, he was mistaken for a local criminal of the same name, arrested and sent to prison. While Nyssa tried to free him, the Doctor tried to warn the prison authorities of an explosion that was destined to destroy them. Realising that it was the Governor herself who would trigger the explosion, the Doctor managed to prevent a catastrophe. (AUDIO: Doing Time)

Taking part in a DVD commentary of a horror film from the 1970s named The Devil's Whisper, the Doctor used the occasion to try and track down an alien parasite known as the Rasht and its "nursemaid" host. In the film was an alien device that enabled a Rasht to possess people who saw it. The Doctor had destroyed all the footage, and planned to use the occasion to contain and destroy the creature. Successful, he and Nyssa departed. (AUDIO: Special Features)

When the Doctor was captured by the Sultan, Nyssa was forced to tell him stories about her adventures with the Doctor for his freedom. (AUDIO: 1001 Nights) One such story was when they encountered the Miaxa in a strange prison. (AUDIO: My Brother's Keeper) A second was about when Nyssa was possessed by the Interplanetarian and how the Doctor exorcised it. (AUDIO: The Interplanetarian) A final story was about when they visited a planet where stories were currency. (AUDIO: Smuggling Tales) Nyssa discovered that the Sultan was a shapeshifter, and that the reason he wanted to hear her stories was because he wanted to steal the Doctor's identity and his TARDIS to escape the planet. (AUDIO: 1001 Nights)

The Doctor and Nyssa visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963. (AUDIO: The Light at the End)

The Doctor and Nyssa encountered the huntress and adventuress Hannah Bartholemew in 1911 Suffolk, and she assisted them during an adventure. (AUDIO: Moonflesh) Hannah then stowed away in the Doctor's TARDIS and assisted the Doctor on an Arrit tomb ship in which the TARDIS had materialised. After that, Hannah joined the Doctor on new adventures in time and space. (AUDIO: Tomb Ship)

On the SORDIDE Delta space station and in the Shadow-Space connected to it, Hannah saved the lives of the Doctor and Nyssa, as well as the fate of billions of humans, but in the process, she was left purged of all emotions, in a robot-like state. She decided to stay on the station along with its similarly afflicted crew instead of going back home with the Doctor. (AUDIO: Masquerade)

The Doctor later escaped the Labyrinth of Death. (GAME: The First Adventure)

The return of Omega
The Doctor was summoned to Gallifrey after dealing with an anti-matter being near the Arc of Infinity. The High Council, led by Lord President Borusa, ordered a Warrant of Termination issued on the Doctor as a form of execution. In the Matrix, the Doctor encountered Omega and Tegan Jovanka. With Nyssa's help, he escaped to Amsterdam in 1983 and found Tegan and Omega, who had created a new body for himself, copying the Doctor's biodata and appearance. The Doctor used the gun of one of Omega's creations to destroy him before Omega could will his self-destruction. With Omega destroyed, the High Council dropped all the charges against the Doctor, allowing him to continue his travels. He also allowed Tegan to rejoin him and Nyssa in the TARDIS. (TV: Arc of Infinity)

While in Amsterdam, the three of them went to a Rembrandt van Rijn exhibition and ended up travelling back in time to the Dutch Golden Age, meeting the famous painter and first trying to help and later defeating a stranded alien in that time period. (AUDIO: The Waters of Amsterdam)

While Tegan and Nyssa relaxed in Amsterdam, (AUDIO: The Elite) the Doctor was called upon by the Time Lords to answer a telepathic message sent by "the Doctor" in the Sector of Forgotten Souls. Upon arrival, the Doctor discovered that Omega had been reconstructed from his biodata, and developed a split personality, believing himself to be both "the Doctor" and Omega. However, the Doctor managed to defeat Omega, and exile him back to his universe of anti-matter. (AUDIO: Omega)

Travelling alone
The Doctor tried to return to Amsterdam, but accidentally arrived on a spaceship in the Drashani Empire carrying a prince called Kylo Sorsha. His arrival indirectly caused the ship to crash into the planet Sharnax, and in the ensuing events Kylo was left stranded on Sharnax. (AUDIO: The Burning Prince)

The Fifth Doctor was taken out of his timezone by the Father of Time to partake in "the Final Test". He was brought to a TARDIS control console room from his future alongside his second, third, fourth and sixth incarnations, and told that Time had disassembled the control console and set the TARDIS on a course for the heart of the sun, with the Doctors' only hope being to reassemble the control console. Unable to achieve the task due to their bickering, the Doctors were saved when the First Doctor united them in reversing time itself with their pooled temporal powers. As the TARDIS escaped the sun, the Father of Time congratulated the Doctor and sent them back to their own times. (COMIC: The Test of Time)

The Doctor was trapped in the Determinant by, along with his six other incarnations. He gave the Graak advice about how to defeat a Sontaran. He was saved after the Graak defeated the Master, and sacrificed its life force to free the trapped Doctors. (GAME: Destiny of the Doctors)

The Doctor briefly bumped into George Litefoot and Henry Gordon Jago, (PROSE: A Victorian Interlude) and attended a private Christmas party hosted by the First Doctor. (PROSE: The Feast of Seven... Eight (and Nine))

Temporary companions
The Doctor discovered that a race of aliens had gone back in time and sent a business woman on her way to a job interview to another planet to die, as her changes to the company would eventually lead to a war in the future between that race and another, and they planned to revert it by killing her before she could join the company. The Doctor found her on the planet after three days without food or water and took her into the TARDIS.

The two travelled together for a year-and-a-half. During one trip, the woman's portfolio was scratched as she blocked the treads of an approaching Warboy with it as "the Big One" came down over her. The woman thought that the travels would last forever, but she eventually decided to leave after she learned of the Doctor's past companions and saw the age and sorrow in his eyes. The Doctor thus returned her to her interview. (PROSE: Time on a Vine)

The Doctor's TARDIS crashed into the TARDIS of his tenth incarnation. After the Tenth Doctor saved the universe from being sucked into the resulting black hole by creating a supernova at the same time as the black hole imploded, which he had remembered to do from the Fifth Doctor watching him do it, the two Doctors bonded over their shared traits, before the TARDISes separated and the Fifth Doctor was returned to his own timestream. (TV: Time Crash)

The Doctor met up with Winston Churchill in 1931 and the two ended up at the field of Blenheim, where they "[threw] themselves under the scant foliage to protect themselves from Marshal Tallard's onslaught". (PROSE: The Lost Diaries of Winston Spencer Churchill)

Finding himself in the TARDIS of his first incarnation, the Doctor was able to convince Vicki Pallister and Steven Taylor of his identity, but soon found himself trying to deal with the social turmoil of Constantinople as a plague struck the city over a year ahead of schedule. The Doctor soon found out that the person behind the switch was, but was unable to stop the Monk's plan to trick him into altering history, allowing the Monk to take the Doctor's place in history.

Fortunately, the Doctor was restored to existence by the Monk's ally, Sophia, who realised that the Monk's attempt to take the Doctor's place was making history worse rather than better, allowing the Doctor to set a trap where the Monk would be forced to restore him to existence. Although learning that the Monk would attempt further attacks on his person, the Doctor mused that he would stop those plans as well, allowing himself to return to his place in history while his first incarnation returned to his TARDIS and let events unfold as they should have done before the Monk's interference. (AUDIO: The Secret History)

The Doctor travelled to Rome in 1511, where he found Gabby and Joel Finch in the wrong time period, and realised that half of the Sistine Chapel's roof wasn't painted. Upon hearing what made Gabby and Joel appear in 1511, the Doctor theorised that a Weeping Angel was on the loose in Rome and thought that Michelangelo must have been attacked by one. Having found the three Angels in the city, he was able to stop them by working with the Finches and Michelangelo to trap them in a crypt below the chapel, using mirrors to ensure that the Angels would always be looking at each other while burying the walls of the chapel itself. (AUDIO: Fallen Angels)

The TARDIS brought the Doctor back to the Racnoss Wars where he saved the Empress’ consort from death at the hands of the Time Lords and took him back to the Racnoss homeworld. There he and two Time Lord prisoners were embroiled in the Empress’ power struggle with the Emperor, whom she had left for dead and had subsequently laid claim to her hatchery to turn her children against her. The Doctor ultimately decided to take the hatchery away from both of them, using the TARDIS to take it to an unpopulated planet where the children could start afresh. He then offered to take the surviving Time Lord prisoner, Alayna, home. (AUDIO: Empire of the Racnoss)

Returning to Amsterdam
On his way back to Amsterdam, (AUDIO: The Furies) the Doctor became acquainted with Brooke, who was actually a proto-Time Lord sent on a mission by Madame Kovarian to kill him. The pair had several adventures together. (AUDIO: A Requiem for the Doctor, The Furies) River Song summoned them to Terminus Prime after burying her sibling Lily and joined them in the TARDIS. (AUDIO: The Lady in the Lake)

The Doctor visited several places with Brooke and River, including Gadalax Prime. However, when they visited Vienna in the 18th century, Brooke spiked the Doctor with Aqua Galatia and used her hatred of him in an attempt to murder him. River neutralised the effect with her love. (AUDIO: A Requiem for the Doctor)

River forced Brooke to take them to where she was set to meet Kovarian, the Bumptious Gastropod, a restaurant outside spacetime. She then wiped the Doctor’s memory to send him away. However he immediately returned to the restaurant and became embroiled in River’s complicated scheme to ensnare Kovarian using a doppelgänger of his, Andrew Edwardson. Despite River’s efforts to keep him out of the way, Brooke seemingly murdered the Doctor using regeneration inhibitors. (AUDIO: My Dinner With Andrew) Afterwards Brooke sided with River against Kovarian and used her vortex manipulator to change history by convincing Andrew to take the Doctor's place. She brought the Doctor in his TARDIS to Concorde Well where he said a brief farewell to River, unaware of her identity, and then set off for Amsterdam. (AUDIO: The Furies)

On his way back to Amsterdam, the Doctor’s TARDIS collided with the Apocalypse Deathwatch, a luxury time cruiser. He worked with a stowaway, Jenny, who claimed to be his future daughter via genetic sampling, to resolve the collision and deal with Vortisaurs, the Nine and Thana who were attempting to capitalise on the disaster. He convinced the Nine to use their TARDISes to shield the cruiser however the Nine noticed they were passing through the broken timestream of Earth and used his TARDIS to try to capture it. Whilst Jenny piloted the cruiser to normal space, the Doctor time rammed the Nine’s TARDIS, telling Jenny he accepted her as his daughter as he did so. The Nine was forced to retreat. Due to the event happening in cauterised time, the Doctor lost all memories of it. (AUDIO: Relative Time)

The Doctor was contacted by Bernice Summerfield, and told that the Sirens of Time had hijacked the test flight of the prototype TARDIS, turning it into a time paradox that was splitting the universe apart. While the experiment had already been stopped, the Time Lords were in danger of not discovering time travel. Along with his third, fourth, sixth, seventh and eighth incarnations, the Fifth Doctor was brought to the planet Henlen to serve as one of the six pilots needed to handle the TARDIS prototype, while his first, second and tenth incarnations dealt with the possible backlash. The flight was successful, restoring the correct timeline and the Fifth Doctor was taken back to his own time by Benny. (AUDIO: Collision Course)

Renewed voyages with Tegan
After picking up Nyssa and Tegan from Amsterdam, thirty seconds after he had left, (AUDIO: The Waters of Amsterdam) the Doctor took them to Florana, where he discovered a lone Dalek had manipulated the population into believing that it was a god. The Doctor tricked the Dalek into revealing its real identity to its greatest "follower", Thane, the High Priest. With his faith broken, Thane killed the Dalek. However, Thane continued with the Dalek's plot to use a weapon called "The Cleansing Fire" to wipe out the population, but he ended up killing himself in the process, along with a percentage of the population. (AUDIO: The Elite)

Arriving on the moon of Akoshemon, the Doctor learned that an entity known as "the Dark" had been imprisoned on the moon millennia in the past, but was manipulating events to ensure its release. Although the mining vessel the Adamantium was destroyed along with most of its crew through the Dark's efforts, the Doctor was able to defeat the Dark by tricking it into fighting a genetically-engineered life form known as the Bloodhunter, with the Bloodhunter wounding the Dark before it was destroyed so that it could be sent back into the abyss where it had been trapped before. (PROSE: Fear of the Dark)

The Doctor tried to help Tegan and Nyssa with their grief for Adric by taking them to the Necropolitan, a huge neutral interplanetary place of mourning. There, he reunited with Verin, a funeral officer whom he had met several times before, and helped him solve a murder. (PROSE: Wake)

Arriving in 1896 London, the Doctor and Tegan discovered that Nyssa had been abducted by a group dedicated to Nephthys, intending to use Nyssa as a new "prison" for Nephthys that could be easier for her to escape. Working with Atkins, the butler of the man who had discovered Nyssa in the tomb of Nephthys, the Doctor and Tegan were able to determine that Nephthys's essence had been divided between instinct and consciousness, with her instinct restored in a clone of her previous host while her conscious mind was trapped in Nyssa. With the aid of Lady Ann Talbot, the Doctor tricked Nephthys into making a series of round trips between 1922 and 1992 via an Osiran time corridor, eventually causing her to age to death while Nyssa was safely restored and Nephthys' consciousness was trapped in a new prison. (PROSE: The Sands of Time)

Taking a break

When Tegan began having precognitive dreams of the Mara, the Doctor decided to deal with the problem on the Mara's home planet, Manussa, where the Doctor sought help from a snake-dancer named Dojjen. According to him, the Doctor had to find his "still point"; the Mara fed on negative emotions, but if one found this internal spot, they would be safe from being fed on. Taking advantage of this knowledge, the Doctor starved the Mara to death, freeing Tegan of its influence. (TV: Snakedance)

In Manchester, the Doctor was attacked by a baby vampire sent by his old Time Lord friend, Ruath, who wanted his blood to resurrect the powerful vampire Yarven, but Nyssa was bitten and became a vampire in his place. The Doctor found Ruath, who was also a vampire, building a machine to freeze time in eternal night to allow vampires to feed forever. The Doctor allowed Nyssa to convert him, and then destroyed the machine and Yarven, changing himself, Nyssa and Ruath back to normal, and then trapped Ruath in the time vortex. (PROSE: Goth Opera)

Leaving Manchester, the Doctor was summoned back to Gallifrey, where he and Nyssa investigated a spate of vampire killings whilst Tegan remained in the TARDIS. They came across a Time Lord cult who believed Rassilon was a vampire. They found the real culprit had infiltrated the TARDIS and infected Tegan. Held hostage, the Doctor was forced to pilot the TARDIS to Earth. However, he materialised in daylight, which destroyed the vampire and returned Tegan to normal. (COMIC: Blood Invocation)

The Doctor, Tegan and Nyssa landed on the deserted spaceship Aquitaine, met the robot Hargreaves and the crew who were scattered through time, and helped to solve the temporal mystery that surrounded the vessel.

When the TARDIS got stuck in a warp ellipse and materialised on a starliner in 1983, the Doctor became trapped at Brendon Public School, where he met a teenage alien in exile named Vislor Turlough, who the Black Guardian persuaded to kill the Doctor in return for being taken back to his homeworld. He also reunited with the Brigadier, who had forgotten their adventures at UNIT and was now a teacher at Brendon's School.

The Doctor found a transmat capsule was responsible for his entrap on Earth; it exploded, sending the TARDIS, containing Nyssa and Tegan, to 1977. After jogging the Brigadier's memory, he and the Doctor went to the spaceship, where the Brigadier from 1977 also was. Mawdryn, one of nine aliens who abused Time Lord technology to become immortal, now wished to die and, at first, it seemed the Doctor would have to sacrifice his remaining regenerations to power a machine to save his companions and kill Mawdryn. Due to the Black Guardian's manipulation of Turlough, the two Brigadiers met and the resulting effect gave the younger Brigadier amnesia and provided power for the machine. The Doctor returned the Brigadiers to their proper times and welcomed Turlough on board, unaware that his latest companion was his assassin. (TV: Mawdryn Undead)

The Doctor was summoned to Gallifrey to track down Ophiuchus, with the High Council wanting to eliminate him for apparently experimenting on Time Lords. Heading to the Cloisters with Tegan, Nyssa and Turlough, the Doctor found Ophiuchus in a secret lab, where he explained that he was trying to break the regeneration limit. As Ophiuchus was dying, the Doctor helped him to regenerate into their fourteenth incarnation and then advised her to flee Gallifrey, promising to tell the High Council that Ophiuchus was destroyed by his experiments. (COMIC: Ophiuchus)

On the Black Guardian's command, Turlough sabotaged the TARDIS, and the ship locked onto a spaceship carrying victims of Lazar's disease to Terminus. Terminus had originally caused the Big Bang and was about to reverse it, destroying the universe. The Doctor charmed the Garm, who prevented the engines from blowing up. Nyssa decided to stay on Terminus to help perfect a cure for Lazar's disease, which upset the Doctor, who was left to travel on with Tegan and Turlough. (TV: Terminus)

While fixing Turlough's sabotage, the Doctor encountered the White Guardian and was ordered to visit an Edwardian yacht-like spaceship piloted by Eternals in a race for Enlightenment. One Eternal, Wrack, sought the prize to end her boredom, and used the Black Guardian's power to destroy other ships.

After the Doctor and Turlough won the race, both Guardians offered them the prize. Realising Turlough was in league with the Black Guardian, the Doctor offered him the prize to test his virtue. Though the Black Guardian tempted him with anything he wanted in exchange for the Doctor's life, Turlough rejected the offer, making the Black Guardian vanish. Although Turlough had been acting against him, the Doctor allowed him to remain aboard the TARDIS, (TV: Enlightenment) which resulted in conflict between him and Tegan. (AUDIO: Cobwebs) Shortly afterwards, the TARDIS landed in Arizona in 1905, where the Doctor came into conflict with travelling showman Thaddeus P. Winklemeyer. (AUDIO: Freakshow)

Nyssa returns
Two days after leaving Terminus, the TARDIS was forced down to the planet Helheim, where the Doctor, Tegan and Turlough reunited with Nyssa, who had lived fifty years since staying behind on Terminus. Nyssa arrived on Helheim to find a cure for Richter's Syndrome, which led her to an abandoned base, where they found robotic Cractids, and four bodies covered in cobwebs, which resembled the Doctor, Tegan, Turlough and Nyssa. To discover what happened to the base, they all travelled to the past, where they discovered that the Cractids were attempting to construct clones of the TARDIS crew, explaining why their bodies were left in the base. The Doctor then used his TARDIS, to divert his TARDIS in the past, to arrive on Helheim in the first place. After the Doctor failed to return her home, Nyssa rejoined the TARDIS crew. (AUDIO: Cobwebs)

The Doctor, Tegan, Turlough and Nyssa arrived on Chodor in the 28th century, where they found a society which was obsessed with cleanliness, and lived under the menace of the Takers. After discovering the truth behind the origins to the corrupt society, the TARDIS crew returned to the TARDIS, but discovered that Tegan was still possessed by the Mara. (AUDIO: The Whispering Forest)

When the Doctor attempted to drive the Mara out of Tegan, it changed its tactics and secretly entered into the Doctor's mind, leaving Tegan completely.

Taking the TARDIS to Manussa after reading about its history, the Mara landed the ship before the rise of the Sumaran Empire, and embarked on a scheme to bring about the subjugation of Manussa in that time period instead, keeping the Doctor as its primary host while possessing several Manussans. However, Tegan and Turlough were able to free the Doctor using a circle of television cameras and screens, and the Doctor linked the crystal the Mara was using as a link to the material world to the TARDIS so he could reverse the creature's physical manifestation. However, the process required that the crystal be in physical contact with the Mara, and the giant snake, fuelled by the despair of the many Manussans it had managed to possess, had swallowed the TARDIS whole. In the end, a young man who had been brought into existence by the crystal technology sacrificed himself by going out into the snake's belly with the crystal, destroying it by "restoring the balance". (AUDIO: The Cradle of the Snake)

The Doctor and his friends landed on Samur shortly before a Sontaran squadron arrived. He learnt that after his previous visit there, the planet was turned into a battleground.

Deciding to repair the TARDIS, following the damage Turlough caused on Terminus, the Doctor landed on Vektris where Tegan and Nyssa decided to have a holiday. Turlough was kidnapped, and the Doctor stole a spaceship to follow his kidnappers. He crashed the ship on Turlough's grandfather's planet.

Geoffrey de Lacey arrived at the castle to confirm the Doctor‘s suspicions and the Doctor saved him from being silenced by Sir Gilles Estram, who revealed himself as the Master after they crossed swords. The Doctor discovered John was actually Kamelion, an android the Master acquired after being stranded by the Doctor in their previous encounter. The Master revealed his plan to use Kamelion to avert Magna Carta’s signing however the Doctor engaged him in a battle of wills and freed Kamelion, bringing him aboard his TARDIS.

The Doctor then escaped the boat to return to his TARDIS, but found the doors still locked, and he was taken to Gallifrey by the Temperon to meet with his sixth and seventh incarnations. Learning that Helen was one of the Sirens of Time, the Doctors were almost tricked undoing their altercations to history, but they instead released the Temperon from the Knights of Velyshaa so that it could trap the Sirens of Time in an eternal struggle. With the Sirens of Time's manipulations to history averted, the Fifth Doctor was returned to his proper place in time by the Seventh Doctor. (AUDIO: The Sirens of Time)

After receiving damage from Sentinel Six, the Doctor landed the TARDIS inside Sea Base 4 in the year 2084, at a time where two power blocs were on the brink of nuclear war. Three Silurians awoke a colony of Sea Devils from hibernation and intended to take over the base, and trick humanity into waging nuclear war against itself by launching proton missiles into space as a final defensive action of the Silurians.

Making plans to return to Frontios for Turlough, the Doctor and Tegan were drawn to Gallifrey by Chancellor Vorena and Castellan Lowri so that the Doctor would be forced into his role as Lord President, as Borusa's political manipulations in anticipation of his immortality had left the High Council unfit to carry out the necessary reforms after Borusa had created a system that depended on his presence, with the Doctor being chosen as the only candidate with the political strength to get things done. With Leela as his unofficial bodyguard and Tegan appointed as Earth's ambassador to justify her continued presence on Gallifrey, the Doctor used the opportunity to make some changes to Gallifrey's political process that he felt were necessary, such as opening new Academies capable of conferring the rank of Time Lord to their students. After a short time in power, during which he conducted a diplomatic mission and averted a student creating a catastrophic paradox, the Doctor finally opened the new Capitol building accompanied by Vorena, Leela and Lowri. After they encountered dimensional anomalies, Vorena confessed the building was a giant TARDIS which she had arranged for him so that he could lead the Time Lords in righting the evils of the cosmos. He eventually chose to reject her offer, with Leela helping the Doctor recognise that taking such a stance would turn himself and his people into tyrants enforcing their will on other civilisations. They were rescued from the malfunctioning giant TARDIS by Tegan and the Doctor took the opportunity to relinquish the presidency, passing it on to Lowri, and depart Gallifrey once more. (AUDIO: Time in Office)

Aided by his other incarnations and their companions, the Fifth Doctor and Tegan helped Dan Dare to fight off the Mekon and his army of Treens, Daleks, Ice Warriors, Cybermen, Sontarans and Draconians in 1991. (COMIC: Comic Relief Comic) They were also present in London during the coronation of Elizabeth II on 2 June 1953, where they encountered a snake creature that was subdued by Eva De Ville. (COMIC: Where's the Doctor?)

After many detours, the Doctor and Tegan collected Turlough from Frontios and became caught in a time corridor. (TV: Frontios) Falling through the time corridor, the Doctor ran into the Daleks loyal to Davros at the London Docks in 1984. The Doctor failed to stop them from attacking the prison ship that he placed Davros in years previously.

After resisting the urge to kill Davros in cold blood, the Doctor unleashed the Movellan virus, which destroyed the Daleks. Having won against Davros, the Doctor was dismayed when Tegan, tiring of the violence and death she had encountered during their adventures, chose to remain in her home time. After she ran away from the TARDIS, the Doctor acknowledged that he needed to change his ways. (TV: Resurrection of the Daleks)

Lone travels with Turlough
Landing in the 18th century, the Doctor and Turlough discovered that an alien psychopathic murderer Carthok had crashed on Earth. Learning that he wanted to kill all life on Earth, the Doctor tricked Carthok's own system into thinking he was one of his targets and his was ripped apart by his former victims' consciousnesses. (AUDIO: Phantasmagoria)

In Brazil in 2080, the Doctor and Turlough encountered a band of Loups-garoux. Ileana de Santos was attracted to the Doctor. Learning of Pieter Stubbe's link to the planet, the Doctor took him away from the planet, which caused Stubbe to die. (AUDIO: Loups-Garoux)

During a visit to the human colony world of Raghi, the Doctor and Turlough discovered a strange new disease that was sweeping the colony, as well as several missing scientists, but soon determined that the Sontarans were the parties responsible for these events. The Doctor realised that Raghi's entire population was being used as bait for a trap, as the disease caused all humans infected with it to register as Sontarans on the Rutan scanners, which would prompt the Rutans to avoid that area of space, and thus give the Sontarans unrestricted access to the Tzun technology hidden on the planet. Contacting the Rutans, the Doctor managed to make a deal with them, exchanging the truth about the colony, while avoiding mentioning the Tzun technology, for their promise not to harm the humans, provoking a conflict between the two enemies that essentially destroyed both parties. (PROSE: Lords of the Storm)

On Heracletus, a planet that had been trapped a time loop by the Time Lords, the Doctor lost the TARDIS and met an alternative version of himself called "the Savant". He and Turlough stopped the Savant, along with the magical being, Spline, from taking revenge on the Time Lords and destroying the fabric of time, before quickly locating the TARDIS before the time loop trapped Heracletus for eternity. (PROSE: Zeitgeist)

The discovery of a mysterious diary in the Time safe led to the Doctor and Turlough learning of the existence of the British Imperial Spacefleet and their trip to the Moon in 1878, as well as their own role in the expedition. Travelling to 1878, the Doctor and Turlough became involved in the expedition's efforts to rescue Captain Richard Haliwell and Emily Boyes-Dennison after they were captured by the Warden, the expedition joining forces with the Phiadorans in the process. The expedition was able to destroy the Warden's citadel, but, after the Doctor was trapped in the dying park and rescued by Kamelion, he realised that the Phiadorans were actually being used as hosts by the ruthless Vrall. Using advanced weapons salvaged from the park, the Doctor, Turlough and Kamelion were able to destroy the Vrall, followed by Kamelion posing as Prince Albert to convince Queen Victoria to abandon the space program, although Richard Haliwell gave the Doctor his diary so that some record of the expedition would remain. (PROSE: Imperial Moon)

Travelling into the past to witness the first encounter of the Neanderthal and Cro-Magnon Man, the Doctor set up a camp and allowed Turlough to leave in his TARDIS, waiting six months until his ship finally returned. However, the Doctor's presence prevented the Neanderthal and Cro-Magnon Man's meeting and caused the death of a Neanderthal, which upset the Doctor. (PROSE: Observation)

The Doctor and Turlough became caught up in the American Civil War in December 1861 and met a dying man, called Samuel, who existed in two different timelines. (PROSE: Comforts of Home)

Soon after, the Doctor and Turlough manufactured a cure for the Atkyan plague that nearly destroyed the Atkyan species. When the cure transformed them into an aggressive species as a side-effect, the Doctor created a stabilising agent that blocked out the side-effect and returned the Atkyan to normal. He was later devastated when he received a mind-link from his second incarnation, telling him that his cure had halved the Atkyans' life expectancy, which wiped out the entire race. (PROSE: One Step Forward, Two Steps Back)

The Doctor and Turlough went to Lanzarote on 9 May 1984 after Kamelion received a distress signal. Turlough brought on board an American girl, Peri Brown, whom he had saved from drowning. The Doctor piloted the TARDIS to Sarn, a colony world of banished Trions. Kamelion had fallen under the Master's control again and was fronting for him as the god Logar. Though he could not prevent the Master from using the flames to return to full power, the Doctor fiddled with the controls, leaving him to burn to death. Now free of the Master's control, Kamelion begged for death, and the Doctor used the TCE on him. Turlough wished to return home, as his exile from Trion had long been ended. The Doctor took Peri on as his new companion for the last three months of her summer vacation. (TV: Planet of Fire)

Early travels with Peri
When a summons from medieval England seemed an unsuitable place to start her travels, the Doctor had Peri remain in the TARDIS library while he investigated. He found that his first incarnation had called upon him and his other incarnations to help him escape a castle surrounded by knights that mistook him for a kidnapper holding Lady Mary hostage in his TARDIS. After he lost the contest to determine who would face the knights, the Fifth Doctor approached the knights to explain the situation and was able to retrieve Mary from the First Doctor's TARDIS. As the Doctors were now permitted to leave, the Fifth Doctor saw that Peri was still travelling with the Sixth Doctor, and realised he would soon regenerate. (PROSE: Five Card Draw)

On their first adventure proper together, the Doctor and Peri led a rebellion on the planet N'Tia, and were hunted by service robots. During this adventure, Peri considered leaving the Doctor as the strain of his dangerous adventures became too much for her. However, the Doctor took her to see a beautiful nightscape with shooting stars, which convinced her to continue travelling aboard the TARDIS. (PROSE: Light at the End of the Tunnel)

After seeing Les Misérables with Peri, the Doctor played a simulation of two species evolving, and attempted to find a way for the two to evolve without conflict. Being unable to solve it, and with the simulation taking up too much space, the Doctor took it to the Proofrock-Mills Intelligence Museum. He then visited the museum a year later and discovered that the problem had had been solved by one of future incarnations. (PROSE: Black and White)

While taking a shopping trip, the Doctor and Peri became caught up in the various quests to find the legendary lost treasure of Rovan Cartovall, who had supposedly vanished centuries ago. Despite some of their more ruthless fellow seekers attempting to use Peri as a hostage to guarantee the Doctor's help in solving the traps, the Doctor and Peri were protected by a unicorn-like entity Peri came to call "Red", who was actually an aspect of Kamelion that had survived his death and been given a new temporary lease of life. Although "Red" sacrificed himself to save Peri, the Doctor was left satisfied as he learned the truth about Cartovall's disappearance, as the man had abandoned his wealth to explore the limitless possibilities of the universe. Other seekers for the treasure either departed satisfied with what they had or were destroyed by their own greed as various traps and twists left them suffocated or locked in artificial realities. (PROSE: The Ultimate Treasure)

On early 21st century Mars, the Doctor and Peri arrived inside the final resting place of the Ice Warrior, Izdaal. After discovering a team from the Argosy enter the tomb at the same time, the Doctor, Commander Lee Forbes and Pilot Susan Roberts travelled to the centre, where the Ice Warriors that guarded the tomb awoke from protecting Izdaal's body. While Peri went to the Argosy to pick up a survival suit, Sub Commander Sstast went to the Argosy to retrieve Peri and the others, but was knocked out by Paul Webster to create a clone army augmented by Ice Warrior biology and technology.

As the Argosy took off, it was fired at with missiles from the tomb, but the Doctor prevented the Ice Warriors from finishing them off. The Argosy crash-landed and Peri, Paul and Tanya Webster returned to the tomb of Izdaal. After Paul took over an Ice Warrior mobile cannon with Tanya and the Doctor as hostage, Lord Zzaal agreed to take the Doctor's place for the safety of the tomb and allowing Paul access to the Ice Warriors' rocket. As the sun rose, the ultraviolet radiation from the "red dawn" burnt Zzaal to death. With Zzaal no longer in mortal danger, Ssast fired a sonic charge at Paul without endangering Zzaal's life. The Doctor and Tanya ran from Paul and survived the attack, returning to the tomb. (AUDIO: Red Dawn)

Visiting Wembley in 1936 to see the FA Cup final, the Doctor helped Edward Grainger to entrap Scanlon, a time meddler who had been stealing famous paintings throughout Earth's history. The Doctor frightened Scanlon away from Earth by threatening him with Time Lord retribution if his meddling continued. (PROSE: The Church of Football)

During a visit to World War I, the Doctor became separated from Peri in the trenches, but she was found in time to enjoy the Christmas Armistice. While waiting for her, the Doctor talked with Edward Woodbourne. (PROSE: Never Seen Cairo)

When a serious injury forced the Doctor to take Peri to Sarn for treatment by Mehendri Solon, he was forced to become the leader of a military campaign against the renegade Time Lord Morbius, adopting the new alias of the "Supreme Coordinator", or "the Supremo" for short, of a large army including the Draconians, Sontarans, Ice Warriors, Cybermen and Ogrons. Eventually, the Doctor's army was able to defeat Morbius's forces, although the Doctor was then forced to make a discreet departure after ensuring that Morbius would survive his death. (PROSE: Warmonger)

Second quest for the Key to Time
Shortly after leaving Mars, the Doctor visited a rainy planet with Peri. He discovered a compass, which was actually a segment of the Key to Time, from one of the derelict ships, The Green Man's Burden. After time was frozen, a sentient tracer sent by the Grace to collect the Key to Time brought the TARDIS off course, asking the Doctor if he could help her collect two more segments of the Key, which had been decaying after the Doctor put it together the previous time. The tracer turned the first segment into its original form and put it into a satchel leading to another universe.

Arriving on Mars in the distant past, the Doctor decided to name the Tracer "Amy", thinking she had agreed upon the name. Amy realised the segment of the Key was disguised as a capstone on the pyramid in the town. The Doctor and Amy were arrested and taken to Magistrate Isskar, accused of being thieves by Isskar's beadles. They were let go with a warning not to approach the pyramid. Understanding but disobeying the warning, the Doctor and Amy met another tracer inside the pyramid, and she already had one of the segments of the Key in her possession, along her assistant in her quest, Harmonious 14 Zink. The Tracer agreed to the Doctor's suggestion of "Zara" as a name. At the top of the pyramid, Zara touched the segment and turned it back into a crystal. This caused a gravity well to appear, causing massive changes to Mars' environment. Zara left with the segment using Zink's Time Ring. The Doctor, Amy and Zink jumped on board an approaching ship, and the Doctor piloted it to safety. Unable to help the catastrophe inflicted on Mars, the Doctor and Amy left in the TARDIS for their next destination. They arrived inside a castle on the ring world of Safeplace, where there was a succession dispute between the Valdigians Lady Mesca Amuntic and Wembik. The Doctor concocted an anti-venom for Mesca, whom Wembik had poisoned because she refused to allow Mesca's son to become king.

Meanwhile, the Ice Warriors, led by Isskar, were guided to Safeplace by Zara to find the next segment, and began fighting the Valdigians. When the Ice Warriors were repelled, Amy worked out a compromise between Mesca and Wembik; they agreed to be married to one another, so that no matter whose son became king, he would also be the son of the other one. While the Doctor asked Isskar to speak to him, his men brought Amy outside the castle grounds. Zara realised the castle was the next segment and turned it into a crystal, trapping the Doctor, the TARDIS, the Valdigians and Isskar inside. The Doctor struggled to hold on, before Amy, having received the segment in her battle with Zara, turned the segment back into a castle, allowing the Doctor, the Ice Warriors and the Valdigians to escape. Amy then turned it back into a crystal and placed it into her satchel.

The Ice Warriors took the Doctor and Amy onto Isskar's ship to take them as tribunal; Isskar confiscated the segments and sent the TARDIS overboard while the ship was in hyperspace in the event of the Doctor and Amy's escape. Zara, being unable to detect Amy's segments, travelled back in time with the time ring, having "wrecked the controls" of the ship. The ship was on a collision course with the red giant, Leboon. Isskar showed Amy her segments, hidden outside time inside a strongbox, which Amy opened. When the last escape pod was taken, leaving the Doctor and Amy behind, the Doctor tried fixing the ship, before the Black Guardian intervened, telling the Doctor that he hoped the Doctor could explain the situation. (AUDIO: The Judgement of Isskar)

The Black Guardian showed the Doctor and Amy a set of potential locations for the Key. Noticing that the Black Guardian was being methodical in his approach, the Doctor told him to randomly send the Doctor and Amy to a location. Landing in Sudan in the 9th century, the Doctor encountered the White Guardian whose powers had waned and was posing as Legate of the Caliph going after tax evaders. He then discovered that the Black Guardian was a tax evader, who was hoarding gold to allow his compatriot the Djinn to repair his ship. When this happened, the Doctor realised that the Guardians had to be involved in its creation and it was beyond time. The Djinn had recovered his TARDIS and he left with Amy for the final piece. (AUDIO: The Destroyer of Delights)

Landing on a Teuthoidian ship, the Doctor encountered Astra who was now president on a rival ship which the Teuthodian's kept attacking. Having being transported to Astra's ship, she told him that she had been living for longer than her fellow Atrions due to the affect of her being released from the Key. Crashing on the planet Chaos, he realised that Zara had kidnapped Amy as Zara thought that he would lead her to the last segment. Having contacted Romana II in the confusion, thinking that Astra was her, the Doctor discovered that after the Key was scattered the last time, Romana had become the final segment of it. To save Romana's life, Astra offered to become the final segment instead, even if it involved her dying to do so. When the White and Black Guardians arrived to try to take the Key away from the Doctor, the Doctor threw it into the Chaos Pool, where it was destroyed, preventing the degradation that it was causing to the universe. While the Guardians left empty handed, Romana returned to Gallifrey, allowing Amy and Zara to accompany her. (AUDIO: The Chaos Pool)

Erimem joins the duo
On a trip to Egypt in 1400 BC with Peri, the Doctor helped save the young pharaoh Erimem from rebels and a conspiracy. He subsequently discoveRed an alien parasite that infected people by touch and controlled them as a hive mind and helped defeat it. Erimem decided to leave her throne to a distant relative and travel with the Doctor and Peri. (AUDIO: The Eye of the Scorpion)

On their way to the Braxiatel Collection, they landed in the 17th century, where Peri was kidnapped as she looked like Queen Anne. Leaving Erimem with Louis XIII, the Doctor went after her and discovered that one of the Queens former lovers, George Villiers, was planning to invade France. (AUDIO: The Church and the Crown)

They visited a market in the Garazone system. Erimem learned of a mystery in the Nelromanteia system, where a war between humanoid soldiers and witches was being fought. The witches killed the Doctor, and he entered a dreamlike plain and learned that the war was over a device that gave immortality. The god of the witches resurrected him and the Doctor, Peri and Erimem escaped before the planet exploded. (AUDIO: Nekromanteia)

Tracking an energy-generating glove to the East End, the Doctor found it in the possession of gangster Charlie Shutter. Fearful of the glove's growing power, the Doctor was forced to go on a crime spree with Charlie and his hitman, Jack. After a week of criminal activities, the Doctor and Charlie plotted to steal a second glove from Charlie's rival, Mickey Green. However, Charlie double-crossed the Doctor and ordered Jack to kill him, Peri and Erimem, but the Doctor had secretly been giving the police information of Charlie's criminal activities, ending his criminal empire. After convincing Jack to change his ways, the Doctor took the gloves to a place where they couldn't be used to cause chaos. (PROSE: The Gangster's Story)

Unfinished business
After getting into an argument with his seventh incarnation, the Doctor dropped Erimem and Peri off for a party in Monte Carlo in 1966 and told them to prevent the theft of the Veiled Leopard. (AUDIO: The Veiled Leopard)

The Doctor visited Clio on her birthday to give her a spare stick of celery as a present, (PROSE: The Glass Princess) had a telepathic conversation with Greenaway to try to prompt him out of his coma, (PROSE: Greenaway) acted as a jury member of the First Doctor's trial, (PROSE: The Juror's Story) and returned to Ca-Mon Green to prevent the Kel-T from tricking another species into mining their resources for them. (PROSE: The Power Supply)

The Doctor met up with William Shakespeare and Richard Burbage at a hostelry and discussed the plot to Shakespeare's upcoming play, Twelfth Night, (PROSE: Diary Extract) and also attended Alistair Gordon Lethbridge-Stewart's funeral with his other incarnations. (PROSE: The Gift)

The Doctor went to the Gogglebox inside the Moon, though his intended destination was the Ice Caves of Shabadabadon. The TARDIS detected unusual energy signatures which appeared throughout Earth history, including 1984 and 2006. As he detected a television transmission which indicated that a future incarnation was investigating 1984, the Doctor went to Brisbane, Australia on 22 September 2006.

While in Brisbane, he met up with Tegan, as well as Dr. Katherine Chambers, who seemed to know about him, and learned that Tegan had contracted an alien brain tumour that was killing her. He offered to take her some place her tumour could be cured, but she was kidnapped by Katherine and an accomplice. Katherine revealed she had been Peri's best friend when they were in school, and that the Doctor, in his next incarnation, would be involved in a plot involving the Cybermen that would result in the paralysis of Katherine's brother and the death of her father. Katherine kidnapped Tegan for the first patient of her new medical computer. The Doctor stopped Katherine and offered Tegan a chance to travel with him again, but she refused, having grown accustomed to her life on Earth. (AUDIO: The Gathering)

Final adventures with Erimem
The Doctor, Peri and Erimem attended the inauguration of the three-bodied lustrousness of the Vix. (AUDIO: The 100 Days of the Doctor)

Landing on YT45, the Doctor, Peri and Erimem became affected by the Kyropites. Not being as affected by the plants as his companions, the Doctor discovered that the Hayton wanted to sell their properties on the open market. Learning that eventually the plants would kill his friends, he used his psychic abilities to enter their dreams. Though he convinced Erimem that she wasn't the ruler of a new Egyptian colony, he had a harder time convincing Peri that she wasn't married with kids. (AUDIO: The Mind's Eye)

The Doctor, Peri and Erimem answered a distress call from the Ice Warrior prince and ambassador, Zixlyr in the 41st century. Zixlyr had blown up an explosive within his ship to smuggle a Xanthoid volataliser onto Peladon after his sister, the previous ambassador to Peladon, Alixlyr, had disappeared; he claimed he had been attacked by Arcturans and knew that if he entered Peladon through more conventional means, the volataliser would have been detected. As the ship began to fall towards Peladon, part of the ship's hull broke off, leaving the TARDIS around Peladon's orbit and making escape impossible. The Doctor, Peri and Erimem helped Zixlyr safely crash land the ship as it entered Peladon's atmosphere, crashing it into a forest. Zixlyr and Peri went to the citadel of Peladon, while Erimem took care of the Doctor as he recovered.

An Aggedor, the daughter of the late Aggedor the Third Doctor had befriended, began approaching the Doctor and Erimem. The Doctor used Erimem's signet ring to hypnotise and tame her. Queen Belldonia of the royal house of Peladon discovered them while on a hunt and escorted the Doctor and Erimem back to the citadel.

An explosion set off by the criminal Arktos and his accomplice, Elkin, had ripped apart the floor of the nearby mines, killing the miners inside. Within the wreckage, Erimem discovered a message in Egyptian hieroglyphs warning of the Osiran Sekhmet, whom the Egyptians worshipped as a god. The Doctor found a secret passageway leading to Sekhmet's trisilicate tomb, where three of her four blood locks had been broken after she fed on the blood of three royal women, including Alixlyr and the newly crowned King Pelleas' predecessor, Queen Elspera, and used the Aggedor to break down the door. Erimem offered her blood to Sekhmet, but had poisoned it with mandrake root that was inside her ring. Zixlyr grabbed onto Sekhmet and set the countdown on his volataliser. Zixlyr sealed the chamber, blowing himself up along with Sekhmet. The Doctor and Erimem escaped, but Erimem was still dying from her poison. Peri used the Time Lord biochemistry in the Doctor's blood to revive Erimem by performing a "very crude" blood transfusion on her.

King Pelleas proposed to Erimem, and she accepted. She parted company from Peri and the Doctor, staying behind to rule Peladon. The Doctor and Peri departed for the TARDIS, still in orbit around Peladon with the help of Alpha Centauri's ship. (AUDIO: The Bride of Peladon)

Final travels
The Doctor and Peri went to the medieval village of Sair and discovered the elders of the town were using witchcraft to ensure the population's survival. One of the elders, Tabilibik, cast a spell on Peri that made her fall in love with him and become his devoted slave. Assisted by the other elders, the Doctor broke the spell and ensured that Tabilibik was punished for abusing his powers. (PROSE: Fascination)

Tracking members of the Celestial Intervention Agency, the Doctor and Peri set up a restaurant, and served the CIA food spiked with a vaccine to a virus the CIA members picked up while investigating the Doctor's recent actions on the planet Pointy. (AUDIO: Urban Myths)

Death
Arriving on Androzani Minor, the Doctor and Peri were caught in a struggle over the mineral spectrox. As they dealt with gun runners, government troops, crooked politicians and a masked madman called Sharaz Jek, the Doctor and Peri were exposed to raw spectrox and contracted the fatal Spectrox toxaemia. Through a perilous descent into the lower caves of the planet, the Doctor managed to get his hands on the milk of a queen bat, the only known cure for the poisoning, but he was only able to recover one dose. He then chose to give Peri the dose, saving her life at the cost of his own.

Succumbing to the poisoning, the Doctor collapsed on the floor of the TARDIS, not entirely sure if he would regenerate, commenting aloud that the regenerative process "[felt] different this time". (TV: The Caves of Androzani) During his regeneration, tried to interfere via Kamelion's lingering connection to the TARDIS, but the Doctor was saved by Nyssa and her husband, Lasarti, who connected with him in his mindscape and helped break the mental link allowing the Master to block his regeneration. (AUDIO: Winter) Seeing visions of his former companions urging him to live and insisting that the universe still had need of him, the Doctor rejected the Master's assertion that he must die and regenerated into his sixth incarnation. (TV: The Caves of Androzani)

After his regeneration, the fifth incarnation became the mental personification of the Doctor's conscience. (PROSE: Timewyrm: Revelation)

When trapped in a dimensionally-unstable pocket universe controlled by Iam and, the Sixth Doctor's morphic print was destabilised, causing him to unwillingly regress back through his previous incarnations as his body sought a stable morphic print. (PROSE: State of Change)

In a bid to detach the Funhouse from the TARDIS in the time vortex, the Sixth Doctor binded the switch that protected the TARDIS' passengers from the changing time fields outside with a string, allowing him to pull it remotely from the limited protection of the Zero Room. As a result, the Doctor immediately began to regress back through his first five incarnations as he made his way back to the console room where, as the First Doctor, he flipped the switch back, restoring himself while trapping the Funhouse in the vortex. (COMIC: Funhouse)

During his seventh incarnation, the mental manifestation of the Fifth Doctor was locked away by the others so that the Doctor could do what he believed he had to do in order to stop the powerful Timewyrm, but when Ace found herself trapped in the Doctor's mind when the Doctor's plan to destroy the Timewyrm by crushing it in his head would have killed her as well, she found and released the trapped Fifth Doctor, restoring the Doctor's conscience and inspiring the Seventh Doctor to find another way. (PROSE: Timewyrm: Revelation)

When the Eighth Doctor was possessed by Zagreus and stabbed by Charley Pollard, he met the mental manifestations of his fifth, sixth and seventh incarnations in his mind when he nearly allowed himself to die, subsequently rallying himself with their aid to restore himself and retake control of the anti-time energies. (AUDIO: Zagreus)

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

During many failed attempts to duplicate the Tenth Doctor, defective copies of all his past incarnations, including the Fifth Doctor, were created instead. (COMIC: Breakfast at Tyranny's)

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

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

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Fifth Doctor, appeared inside it to defend themselves as well. When the Fourth Doctor told auditor Sondrah that neither the T'keyn nor the Time Lords would understand his love for the Earth, the Fifth Doctor recalled his efforts to change the Time Lords, and then reflected how the people of Earth had inspired him to better himself. When the Eleventh Doctor began to deduce Sondrah's true identity, the past Doctors faded away as Oscar Wilde interfered with the Nexus. (COMIC: Dead Man's Hand)

Alternate timelines


In one timeline, the Doctor was able to save Adric. (PROSE: So Vile a Sin)

In a negated timeline, the Doctor and Nyssa followed mysterious coordinates to 23 November 1963, but the Doctor landed the TARDIS earlier than the coordinates indicated to avoid a trap. Investigating their surroundings, the Doctor and Nyssa were approached by Bob Dovie, who mistook them for the police officers he had contacted about his missing family, and discovered that Dovie's wife and children had been murdered by. As they made their way back to the TARDIS, Dovie followed them, and his refusal to believe in the TARDIS set off the conceptual bomb the Master had planted on him, causing the TARDIS to explode, but the Doctor was saved by his sixth incarnation. Joining with his other selves to formulate a plan to stop the Master, the Fifth Doctor realised the solution was to visit Dovie a year earlier and introduce him to the TARDIS, so that he would find it more believable when he had the conceptual bomb and it would not go off. Once his plan succeeded, the Fifth Doctor joined his other seven incarnations in preparing to time ram the Master's TARDIS. However, rather than kill the Master, the First Doctor instead turned off the automatic distress actions, which had brought all of the Doctors to the pocket dimension and triggered the TARDIS' destruction, making it so none of that had happened. (AUDIO: The Light at the End)

In an alternative timeline, the Doctor had his brain fried by the computer while substituting for a dead synch-op on Sea Base 4 in 2084. (PROSE: So Vile a Sin)

When the Cybermen allied with Rassilon to take over history, (COMIC: Supremacy of the Cybermen) the TARDIS was caught in a time corridor that led the Doctor and Peri to Skaro, which was occupied by the Cybermen, who began to attack, (COMIC: Prologue: the Fifth Doctor) forcing the Doctor and Peri to flee. This timeline was eventually unwritten by Rassilon and the Twelfth Doctor. (COMIC: Supremacy of the Cybermen)

In an alternate timeline created by the influence of the Valeyard using the Dark Matrix, the Fifth Doctor was able to resist the Valeyard's influence for most of his life, but he eventually succumbed at what would have been his regeneration, taking the bat's milk antidote to the Spectrox toxaemia and letting Peri die in his place. This timeline was eventually undone by the Seventh Doctor. (PROSE: Matrix)

In one timeline, the Doctor permanently died on Androzani Minor due to the Great Intelligence's interference. (TV: The Name of the Doctor) In a different alternative timeline, the Doctor never went to Androzani Minor. (PROSE: So Vile a Sin)

Personality
The Fifth Doctor was the most open and vulnerable of all the Doctors, coming across as naïve and inexperienced, acting like a child excited to see new worlds and foreign places. (TV: Castrovalva, Earthshock) He was neither pretentious nor selfish and reacted to situations rather than starting them, with his humanity making him panicky and indecisive under pressure, but he would use dissembling and deceit in order to avert a crisis or defeat an adversary. (TV: Frontios) His young appearance was reflected in the youthfulness of his companions, whom he treated like friends rather than subordinates, with their pain and sorrow affecting him deeply, (TV: Earthshock, Resurrection of the Daleks) and their safety his top priority. (TV: The Caves of Androzani) He also felt suited for settling down and starting a family. (AUDIO: Loups-Garoux, No Place Like Home, Winter)

However, the Doctor's boyish appearance, nervous energy, and charm all hid the fact that he was a Time Lord of great age, compassion, and experience. He was willing to take chances with companions like Vislor Turlough and Kamelion, who were originally threats, (TV: Mawdryn Undead, The King's Demons) even as he pretended to be unaware of it in order to grant Turlough the opportunity to do the right thing. (TV: Enlightenment) He was also willing to make enormous personal sacrifices simply to keep his word and liberate others from suffering, (TV: Mawdryn Undead) and would stop and help others while dealing with greater threats. (TV: Arc of Infinity)

Despite his youthful body and love of cricket, the Fifth Doctor was one of the least physical Doctors, preferring to use diplomacy to solve a problem. He was, however, still very capable when pushed to physical confrontations. (TV: The King's Demons) He gained trust by proving himself instead of using his vast experience as an excuse to take charge. Indeed, he worked willingly under the leadership of others who had the strong command presence that he lacked. This did not mean he did not take charge in moments of intensity, (TV: Kinda, Resurrection of the Daleks) or frustration. (TV: Time Crash) He was notably sarcastic, especially towards Tegan and Adric, but usually in the politest way possible. (TV: Castrovalva, The Five Doctors, Frontios)

After finding a cricket bat and discovering a room in his TARDIS dedicated to the sport shortly after his regeneration, the Fifth Doctor became a vivid fan of cricket, (TV: Castrovalva, Black Orchid) attending several famous matches, (AUDIO: The Roof of the World, Nekromanteia, The Emerald Tiger; PROSE: Graham Dilley Saves the World) and teaching his companions the rules of the game. (AUDIO: Phantasmagoria)

He felt a genuine sense of awe while in Cairo, (PROSE: Never Seen Cairo) and though of Vortis as somewhere he could relax. (AUDIO: Return to the Web Planet)

The Fifth Doctor disliked being referred to as "sweet", (AUDIO: The Entropy Composition) had a disdain for cats, (AUDIO: No Place Like Home) felt uncomfortable around spiders, (PROSE: Light at the End of the Tunnel) and, with the exception of Susan, rarely thought about his family. (AUDIO: No Place Like Home) He also disliked slavery. (PROSE: Tip of the Tongue)

He took his tea with either two sugars (AUDIO: The Eternal Summer) or with milk and no sugar, (AUDIO: The Elite) and liked jam, (AUDIO: Plague of the Daleks) kippers and porridge. (PROSE: Empire of Death) He considered fresh chilled orange juice to be "one of the finest things about Earth". (PROSE: Fascination)

The Doctor looked for "possibilities" that he "[could] never imagine", as he wanted to know how they worked and help them to work better. (AUDIO: Loups-Garoux) He liked having likes audience participation in large shows. (AUDIO: Nekromanteia)

He identified himself as open-minded, likening himself to Alice as he "tried to believe three impossible things before breakfast". (TV: The Five Doctors) He also tried to find a positive approach to life, even if it was a delusional one, (AUDIO: Iterations of I) fixating on the idea that Mondas was 1950s Trafalgar Square, wilfully ignoring the mine carts and giant underground cavern overhead, (AUDIO: Spare Parts) and when he and Nyssa were arrested for using future currency during the Jacobin era, the Doctor consoled Nyssa by pointing out that they still used Earth-based coins. (AUDIO: Summer)

Disdainful towards needless deaths, (COMIC: In Their Nature) the Fifth Doctor showed a great loathing for violence, bloodshed and the pain and suffering of others. (TV: The Visitation, Warriors of the Deep) He failed to execute Davros in cold blood, (TV: Resurrection of the Daleks) and, at the android's request, reluctantly killed Kamelion. (TV: Planet of Fire)

Despite this, he did possess a dark side, gunning down foes when he deemed it necessary, (TV: Earthshock, Arc of Infinity, Resurrection of the Daleks) and did not move to save from a fiery death, though was deeply upset by his part in it. (TV: Planet of Fire) He could lose his temper when pushed too far, (TV: Arc of Infinity; AUDIO: Spare Parts) or when around someone who annoyed him, (TV: Time Crash) and also showed off an immature and childish side when he argued with Adric about returning to E-Space, a place he personally did not want to go to, coming up with every excuse he could to prevent them from going. (TV: Earthshock)

He was also willing to physically slap someone to calm them down, as with Maxwell Edison. (COMIC: Stars Fell on Stockbridge) He could also get impatient with those around him, especially his companions. (TV: Earthshock, Snakedance) He once shot the Master non-fatally in the chest to subdue him, (PROSE: A Town Called Eternity) and accepted a pistol from King Louis, but only so he would not contradict the king. (AUDIO: The Church and the Crown)

Being an open minded individual, the Fifth Doctor was willing to give his enemies the benefit of the doubt, such as when he met in the Death Zone on Gallifrey, and was willing to hear him out when the Master said he had come to aid the Doctor. When the High Council confirmed the Master's story, the Doctor admitted that he had done the Master an injustice by doubting him. (TV: The Five Doctors)

Towards the end of his life, the Doctor displayed a more relaxed and controlled side. Even as he awaited execution on Androzani Minor, he was fiercely curious about the spectrox mined there. He still retained his sarcastic side, mocking Chellak's insistence on being addressed as "sir", and reacting with humour to Sharaz Jek's idea of him, the Doctor and Peri becoming "the best of companions". (TV: The Caves of Androzani)

The Fifth Doctor though his third incarnation was the "dandiest dandelion", while the Third Doctor criticised his fifth incarnation for "wearing [a] salad". (WC: Doctors Assemble!)

Immediately after his regeneration, the Sixth Doctor claimed that his predecessor had "a sort of feckless charm [that] simply wasn't [him]", (TV: The Twin Dilemma) but later admitted to Evelyn Smythe that "being him was like a holiday", adding that it was "a very wonderful holiday". (AUDIO: The 100 Days of the Doctor)

The Seventh Doctor described the Fifth Doctor as "bland" and "not even one of the good ones", while the Fifth Doctor was repulsed by his seventh incarnation's manipulative nature. (PROSE: Cold Fusion) However, despite the animosity between the two, in the Seventh Doctor's subconscious, the Fifth Doctor, due to his strong sense of compassion, personified his conscience. (PROSE: Timewyrm: Revelation) The Eighth Doctor was fonder of his fifth incarnation than his two immediate predecessors, describing him as "terribly polite." (AUDIO: The Four Doctors)

The Tenth Doctor expressed a fondness for his fifth incarnation, seeing him as a turning point and stating that it was after his fourth regeneration when he began to enjoy his time in younger bodies. He also confessed that certain aspects of his wardrobe and personality were influenced by the Fifth Doctor. (TV: Time Crash)

When the Eleventh Doctor contacted the Fifth Doctor through an Ovid sphere in England in the 1920s, he commented that his fifth incarnation was "grumpy" and "frowny" in part because he worried about being taken seriously due to his youthful appearance. (AUDIO: Smoke and Mirrors)

Although he and Tegan often argued, he told Lady Adela Forster that she was "very dear" to him, (AUDIO: The Emerald Tiger) and told Tegan that he "[couldn't] bear the thought of not having [her] around". (PROSE: Qualia) In spite of this, the Doctor would often hide from her in the TARDIS' Cloister Room. (AUDIO: No Place Like Home) Tegan claimed that the Doctor often gave her "half pained, half patronising" looks. (AUDIO: Aquitaine)

Two days after he recovered from his post-regeneration trauma, Tegan described the Fifth Doctor as "an incompetent lunatic who talks gibberish", and Adric saw him as an inferior replacement to the Fourth Doctor and a "feckless, frivolous dilettante". (AUDIO: Psychodrome) At a later date, Tegan described him as "the most annoying man that [she had] ever met". (AUDIO: Aquitaine) On one occasion, she derisively referred to the Doctor as a "posho". (AUDIO: The Peterloo Massacre) When the Eighth Doctor had a tarot card reading, the Fifth Doctor was identified as "the Star". (PROSE: The City of the Dead)

Roz Forrester did not trust the Fifth Doctor, as she believed the fact that he seemed so trustworthy was suspicious. (PROSE: Cold Fusion) River Song noted the Fifth Doctor's "sweet, but strangely short-tempered," personality, as well as his obsession with the Eye of Orion. (GAME: The Eternity Clock)

believed that the Fifth Doctor was "the nice one [with] such charm, innocence, [and] naiveté", (GAME: Destiny of the Doctors) while described him as "the drippy blonde one" who "wander[ed] around like nobody's ever played cricket ever". (AUDIO: The Two Masters) Helen referred to him as "the Compassionate". (AUDIO: The Sirens of Time)

After he and Peri became infected with Spectrox toxaemia, the Doctor became determined to save Peri from dying of the poison; stealing a spaceship, outrunning armed mercenaries, climbing deep into a cave with no oxygen and back, and finally carrying Peri to the TARDIS while in the paralysis stage of the poisoning, (TV: The Caves of Androzani) all while holding back the regenerative process. (AUDIO: Winter) When in the safety of the TARDIS, the Doctor gave Peri all that remained of the antidote, saving her life at the cost of his own. (TV: The Caves of Androzani)

Habits and quirks
In an occasional reminder of his actual age, the Fifth Doctor would sport a pair of glasses when examining something. (TV: Castrovalva, Kinda, Frontios) These were his "brainy specs", which he wore to make him look "a bit clever". (TV: Time Crash) He often delegated some decisions to a simple flip of a coin. (TV: Kinda)

To encourage others, the Doctor would tell them to have a "brave heart", especially with Tegan. (TV: Earthshock, Enlightenment, Warrior of the Deep, The Awakening) He was also known to say, "Sorry, must dash", especially when leaving in a hurry. (TV: Time-Flight, The Five Doctors) Like his third incarnation, he would affectionately address people as "old chap". (AUDIO: Zagreus)

Typically, the Doctor would either stand with his hands in his pockets, flicking the long tails on his coat back in the process, (TV: Earthshock, The King's Demons, The Five Doctors, The Caves of Androzani) or stand with his hands crossed behind his back. (TV: Four to Doomsday, Earthshock, Arc of Infinity, The Five Doctors) He was also prone to dramatic turns, which usually caused his hair to sway wildly. (TV: Castrovalva, Earthshock, Mawdryn Undead, The Five Doctors, Warriors of the Deep, Resurrection of the Daleks)

Skills
The Fifth Doctor was highly skilled at the sport of cricket, (TV: Black Orchid) often spending long periods of time playing the game. (PROSE: Happy Endings, Goth Opera; AUDIO: Autumn) He was a "strong right arm bowler ". (AUDIO: The Council of Nicaea)

He also retained the sword fighting acumen and unarmed combat skills of his predecessors, although the latter was showcased sparingly, and only in self-defence. (TV: The Visitation, The King's Demons, Warriors of the Deep, Resurrection of the Daleks) He possessed the strength to break the neck of a pterodactyl-like creature with his bare hands, (PROSE: Warmonger) and was also an expert marksman with a bow. (PROSE: The Immortals; AUDIO: Son of the Dragon)

After learning how to, (COMIC: 4-Dimensional Vistas) the Doctor was able to swim out of danger, even while dazed, and was capable of holding his breath for a long period of time. (TV: Warriors of the Deep)

The Doctor could perform hypnotism, (PROSE: Empire of Death) and was able to make limited telepathic contact with the Xaranti. (PROSE: Deep Blue) He claimed to have "superior psychic defences", (AUDIO: Rat Trap) and believed himself to be immune to hypnotism. (AUDIO: The Butcher of Brisbane)

The Doctor could decipher the ingredients of a drink by smell (TV: Castrovalva) or taste alone; (AUDIO: A Requiem for the Doctor) rosemary made him sneeze. (TV: Castrovalva)

The Doctor was capable of driving a chariot, (AUDIO: The Eye of the Scorpion) and could ride a horse. (AUDIO: The Church and the Crown)

The Doctor had a "gift for languages", (PROSE: Fear of the Dark) and could speak to a Croatian in his native language. (AUDIO: Autumn) He could also speak Greek. (AUDIO: Exotron)

The Doctor often showed keen observational and deductive skills, quickly solving the mystery of the murder of Sinead Iona Fleming on Fleming's Island fifty years after the crime (AUDIO: Iterations of I) and managing to piece together the true nature of the Vrall from a few scattered clues relating to the anomalous behaviour of the Translation circuit. (PROSE: Imperial Moon)

He carried a Molenski Univarius, that he claimed could fix anything, (AUDIO: The Axis of Insanity) learned how to perform coin magic from Adric, (TV: Kinda) and could recall and quote from scripture. (AUDIO: The Council of Nicaea)

Appearance
The Fifth Doctor resembled a young man in his late twenties, (TV: Logopolis) with, as Peri Brown described, "fair blonde hair, blue eyes, and a sweet smile". (AUDIO: Peri and the Piscon Paradox)

Rose Tyler considered the Fifth Doctor to be a "rather hot blond man" when Clive Finch showed her his picture. (PROSE: Rose)

The Second Doctor playfully called his fifth incarnation "a youngster". (COMIC: Endgame)

When Affinity took on the Fifth Doctor's appearance to approach the Twelfth Doctor, he noted that the fifth incarnation was a "young fair-haired man in a pale coat and light striped trousers." (PROSE: Silhouette)

Hair and grooming
As a side-effect of his regeneration, (PROSE: Cold Fusion) the Fifth Doctor's hair regularly changed length, ranging from really short to long enough to reach his shoulders. (TV: Logopolis, Castrovalva)

Once, to make himself appear older, the Doctor grew a beard while he was stranded in 1867 London that helped him fit in with the scientific community. (AUDIO: The Haunting of Thomas Brewster) He grew a beard again when he was forced to escape a prison through a time field that caused him to age a relative year while spending only a few minutes in it from an outside perspective. (AUDIO: Doing Time)

Main attires
The Fifth Doctor's first outfit featured a long beige-coloured frock coat with red piping along the collar, lapels, sleeves, pockets and tails. Underneath this he wore a white, long-sleeved cricket jumper with a red and black V-Neck pattern, and, under that, a white dress shirt with a red interior and embroidered red question marks on the collars. His trousers were a unique pattern of brown and beige stripes. He also wore white plimsolls. He would top the look with a roll-up Panama hat that had a red band with a black and white pattern. (TV: Castrovalva)

After his clothes were ruined in the waters of Sea Base 4, (TV: Warriors of the Deep) the Doctor changed to a French grey coat with a longer collar and a jumper with a pattern of thick red and black lines on the bottom, the V-neck and sleeves. The dress shirt had a green interior and the pattern of the trousers changed to thick, orange lines. (TV: The Awakening) He sometimes wore suspenders adorned with question marks and, on one occasion, replaced his jumper with a beige coloured waistcoat that had a gold, white and red flora & fauna pattern. (TV: Planet of Fire)

He wore a stick of artificial celery on his left lapel (TV: Castrovalva, Enlightenment) to alert him to his allergy to gases in the praxis range of the spectrum, as the celery would turn purple in their presence. (TV: The Caves of Androzani) Ironically, the Doctor himself hated celery. (AUDIO: The Gathering)

Other costumes
The Fifth Doctor slept in white pyjamas, with tiny question mark motifs sewn on to them. (PROSE: Divided Loyalties)

When his first incarnation was placed on trial in 1963 London as a result of killing a werewolf with a silver bullet, the Fifth Doctor dressed in an ill-fitting grey suit. (PROSE: The Juror's Story)

While in Cairo, the Doctor wore khaki trousers and an off-white shirt. (PROSE: Never Seen Cairo)

Whilst on Karn with Peri, the Doctor donned a fur coat and boots, and also wore a black dress suit. As "the Supremo", he wore a black military uniform. (PROSE: Warmonger)

Whilst on the Crystal Bucephalus, he wore a puffy shirt and a blue cloak. (PROSE: The Crystal Bucephalus)

Casting
After the popular fourth incarnation, it was decided that the next incarnation should be played by an actor who was already firmly established in the British public's mind. Peter Davison was chosen, due in no small part to his popular and critically acclaimed role as Tristan Farnon in All Creatures Great and Small, a BBC series based on the books of James Herriot.

Richard Griffiths was considered for the role before Peter Davison was cast, as was Iain Cuthbertson.

The age gap
Only 29 when cast, he remained "the youngest Doctor" until the 2009 hiring of 26-year-old Matt Smith. He was some eleven years younger than Tom Baker, the previous record holder, seven years younger than Paul McGann, and five years younger than future son-in-law, David Tennant. He was later recast as the Fifth Doctor in Time Crash in 2007, at which time he was 56, a year older than William Hartnell was during the filming of An Unearthly Child.

Bad hair years
To a degree never seen with any other regular character before or since, the Fifth Doctor was at the heart of a running continuity error. No make-up artist seemed to particularly care about the length of Davison's hair throughout season 19, despite the fact that it was known that serials were being recorded out of broadcast order.

Davison, a busy actor with other commitments, had his hair cut short at the beginning of Doctor Who's production blocks, because other projects like All Creatures Great and Small required it. For reasons unclear, he was then allowed to grow his hair several inches while filming as the Fifth Doctor. However, since the episodes aired out of order, his hair length quite obviously varied.

Were it not for the fact that most serials of season 19 narratively dovetailed into each other, it might be possible to simply believe that the character simply liked to go to the barber shop between stories. Unfortunately for this theory, Four to Doomsday was narratively tied to the beginning of Kinda, so the jarring hair growth can only be regarded as a production error.

Davison cut his hair prior to each season, and the production team allowed him to grow it throughout each of his production blocks. However, Snakedance was the final story of his tenure broadcast out of production order, and Arc of Infinity didn't obviously lead into it. Thus, although Davison was again allowed to grow his hair throughout the production of seasons 20 and 21, it never amounted to the kind of production error it was throughout season 19.

It's frequently remarked by Davison on DVD commentaries that real fans can tell the production order of episodes by the length of the Fifth Doctor's hair.

Brainy specs
In several DVD commentaries, Peter Davison claims he abandoned his half-moon glasses because Janet Fielding teased him when he used them. Fielding seemed to agree with this assessment on the commentary for Earthshock.

Celery
Davison agreed to wear a stick of celery on his lapel on the understanding that JNT would eventually have a writer explain the bizarre fashion statement. Though Davison thought the explanation would come earlier, the mystery was at last revealed in his final story. (DCOM: The Caves of Androzani) Ironically, Davison hated celery. When he was required to eat celery during the recording of Castrovalva, he found it deeply unpleasant. (DCOM: Castrovalva)
