Youthful in appearance, the Fifth Doctor was a put-upon adventurer who tried to follow the principles of fair play in a universe that bedevilled him with great tragedy and violent endings, leading the Doctor to better appreciate the "small, beautiful events" in life. While he held a keen interest in science and exploration, his greatest love was cricket. Being highly eager to see new discoveries, he was prone to being easily distracted and getting caught up in his own thoughts, sometimes to the point where he got himself and others into trouble simply by not paying enough attention, and would find misunderstandings with local authorities landing him imprisoned due to his preference to being honest and reserved instead of making himself an imposition. Indeed, the Doctor struggled to take actions he deemed immoral, and became highly conflicted about the choices he could make in a crisis, with his hesitancies making him seemingly more fallible than his other incarnations, though he remained one of the most overtly fearless incarnations, frequently finding himself right in the thick of battle.

Starting his life by defeating his archenemy, the Tremas Master, at Castrovalva, the Fifth Doctor inherited a team of companions from his fourth incarnation; Adric, Nyssa and Tegan Jovanka. In his early travels, the Doctor often found himself stuck between Tegan's pessimism and Adric's arrogance, with Nyssa helping him stand as a voice of reason as they attempt to return Tegan to Heathrow Airport, though instead found the TARDIS landing at places such as Monarch's ship and the planet Deva Loka, where the Doctor did battle with the Mara for the first time. However, after an adventure in 1666 London, which saw the Doctor's sonic screwdriver destroyed by a Terileptil, Tegan decided to forgo returning to her old life and instead enjoy her travels with the TARDIS crew, such as a party at 1925 Cranleigh Hall. However, the disadvantages of having three traveling companions showed themselves when Adric began to feel unappreciated when compared to Nyssa and Tegan, and his need to prove himself led to him pointlessly sacrificing his life during a battle with the CyberNeomorphs when he attempted to prevent a space-freighter from crashing into prehistoric Earth, not knowing it was the fixed point in time that lead to the extinction of the dinosaurs. As the Doctor, Nyssa and Tegan tried to process Adric's sudden death, the TARDIS ironically landed at Heathrow Airport, where, after a battle with the Master, the Doctor and Nyssa left Tegan behind.

The Doctor and Nyssa's jaunts through time and space saw them bear witness to the creation of the Cybermen on Mondas, become stranded in 1867 London after Thomas Brewster stole the TARDIS, and enjoying brief travels with Brewster and Hannah Bartholemew. A brief break from Nyssa saw the Doctor team up with Shayde and Justin of Wells to fight Melanicus in Stockbridge, and meet Maxwell Edison, as well as briefly travel with Gus Goodman until he was killed by the Moderator. A chance reunion with Tegan in Amsterdam coincided with the Doctor seeing his old foes return again, such as Omega and the Mara, and bumping into his tenth incarnation, while his own inability to mourn Adric eventually caused the Doctor to take some time apart from his companions when Marcipor, a Greek slave who had joined the TARDIS crew after being freed, was partially cyber-converted. Marc later left to stay on XB93.

The return of the Black Guardian saw Vislor Turlough, a Trion exiled to Brendon Public School, join the TARDIS crew on the Guardian's orders, so that he may assassinate the Doctor, and then saw Nyssa depart to help treat the victims of Lazar's disease on the Terminus space station. In the battle for Turlough's allegiance, the Doctor was able to convince him to defy the Black Guardian with Enlightenment. While attempting to return Turlough to his home planet, the TARDIS crew found themselves re-joined by an older Nyssa, until she elected to remain in E-Space. The Doctor then found himself picking up a new companion in Kamelion, a shape-changing android he liberated from the Master at 1215 Fitzwilliam Castle. However, Kamelion's inability to ward off the influence of strong minds lead him to decide to remain within the TARDIS indefinitely, just as the Doctor brought the TARDIS to the Eye of Orion for a holiday that left him and his previous incarnations forced to partake in the Game of Rassilon by, who sough the immortality promised by Rassilon, but Borusa was instead imprisoned in stone, with the High Council offering the Doctor to succeed him in the Presidency, an offer he declined.

As his travels continued, the Doctor, Tegan and Turlough found themselves embroiled in more grisly escapades, such as a complete massacre on Sea Base 4, though a holiday in 1984 Little Hodcombe offered a short reprieve from the bleakness, until they saw first-hand the despair of human survivors on Frontios in the far future. Tegan opted to leave the TARDIS when witnessing the casualties of the Daleks extraction of Davros to cure the Movellan virus proved too much for her. Turlough himself would leave after he found that his exile on Trion had ended during a holiday at 1984 Lanzarote, which also saw Kamelion killed when he could no longer fight off the Master's control of him and the Doctor was joined by Peri Brown, an American student Turlough had saved from drowning.

In their adventures together, the Doctor and Peri were joined by Erimem, an uncrowned Pharaoh from ancient Egypt, until she decided to settle down with King Pelleas on Peladon. During a side adventure without Peri, the Doctor was forced to reassemble the Key to Time with the humanoid tracer Abby, and then became embroiled in the exploits of her and her "twin sister", Zara.

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 was only able to save enough for one person in his last trek to the TARDIS, and gave it all to Peri, gambling on a regeneration saving his life. Despite the Master trying to mentally interfere with the process, the Doctor successfully managed to regenerate into a new body with the aid of Nyssa and Kamelion.

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)

When he met the Tenth Doctor at the Cathedral of Contemplation, the Fourth Doctor noted the implication that his tenth incarnation also represented all the lives he would live until the the Tenth Doctor arrived at the Cathedral. (AUDIO: Out of Time)

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
"Well, that's the end of that. But it's probably the beginning of something completely different."

- The Fifth Doctor's first words

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)

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)

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 and his friends 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)

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)

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)

The Doctor decided to teach Adric how to pilot the TARDIS. When Adric failed a test flight, the Doctor took the TARDIS crew to Gallius Ultima to teach them more about astronomy, but he miscalculated the landing. He went with Fell on a mission to find out what happened to the humans' spaceship in the Larger Magellanic Cloud and discovered the Star Men. The Doctor realised that Rovus was changing the timelines and warned him that if he tried to control the universe, people would attempt to stop him. (AUDIO: The Star Men)

The Doctor started to think that something was stopping him from getting back to Heathrow. When the TARDIS lost power, it landed in the Contingency Club. The Doctor was evicted from the club house and thought something was strange when the dimensions outside didn't match the dimension inside, it was much much larger on the outside, making him think that there was a hidden chamber inside. He learnt that the Red Queen was playing a game to take over the Earth with her brother, the Knave. (AUDIO: The Contingency Club)

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)

As part of Adric's pilot training, the Doctor showed him how to plot a course through the vortex, but there was a problem with the console. The Doctor and company landed on Cicero Prime shortly after this. He was arrested with Nyssa and taken to Sebastian thinking he would find Adric and Tegan there. He was mistaken to be the Scorpion. He didn't want to do the assassination but was later accused of it. He later tired to council the royal couple. The Doctor realised that Amelia and Tomek were the same people. He then tried to negotiate with the real Scorpion. (AUDIO: Kingdom of Lies)

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 travelled to Argentia to collect the relevant crystals he needed to create a new sonic screwdriver. After being caught by Galgo, he had to pretend that he and his colleagues where there to attend the funeral of Carlo Mazzini. After a set of murders, he helped to investigate who did them. He interrogated Maria Mazzini, who was enamoured with him, but she died shortly afterwards. The Doctor was arrested for all the murders. After being locked in the cell, he worked out that Angelo Mazzini was the killer. (AUDIO: Serpent in the Silver Mask)

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)

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 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 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)

After having a laugh with Tegan and Nyssa in the control room, (POEM: 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)

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)

Losing Adric and Tegan
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 Doctor was left haunted by his inability to save him for centuries, (COMIC: The Forgotten) leading 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
While Nyssa stayed in the TARDIS, the Doctor entered a school occupied by boys who had been detected by an advance race as being destined to commit acts of terrorism and had frozen them in childhood and confined them to the school. However, one of the boy's destined terrorist attacks took physical form and sought revenge for its denied existence by killing the boys. In order to defeat it, the Doctor had to surviving boys concentrate on their inner darkness, creating another monster that merged with the killer and they both killed each other. (PROSE: Long Term)

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)

The Doctor and Nyssa arrived in 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)

After Nyssa disappeared whilst the Doctor was making a Spillager detector, he tracked her to a boarding school in Switzerland in 1963. Investigating the poltergeist activity in the school, he discovered psychic ability in the two pupils Alison Speer and Peril Bellamy and deduced they had been brought together by Spillager scouts to open a gateway to allow them to invade. He had the girls turn their abilities on the scouts, but they were too worn out to stop the invasion forcing the Doctor to turn to Nyssa, whose rudimentary abilities proved sufficient to close the gateway. Afterwards the Doctor gave Alison and Peril a lift home in the TARDIS. (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 shortly after they left. (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 took Nyssa to see his old friend David Gosthorpe, only to arrive after his death from a stroke, and to find his family home, Trentillys Castle, in a state of disrepair. David's sister, Ellen Carter, tried to salvage some money from old relics, but was accidently killed by one that hailed from Tarron. The Doctor and Nyssa disposed of the relic by throwing it in the castle pond. (PROSE: Past Reckoning)

When the TARDIS was drawn to Carnon Manor, the Doctor and Nyssa confronted Lord Nicholas Carnon, who had struck a deal with Death to have six souls at the moment of death to amuse himself in return for delivering the Doctor into Death's hands. However, when Carnon offered to restore his captives to life if they killed the Doctor, the ones that were not overpowered turned on Carnon, and Death took him for failing to keep his bargain, causing the house to vanish. (PROSE: The Eternity Contract)

During a trip to Greenford, the Doctor discovered that the Xyz had conqured the Earth with their television series, Surrender, Earthlings!, but the Doctor and Nyssa were able to persuade the BBC to cancel the show by convincing them that it had low ratings. (PROSE: Not So Much a Programme, More a Way of Life)

When the TARDIS responded to a mental distress signal, the Doctor found himself comforting Imogen Quaye, an orphaned teenager who had had her intelligence greatly increased in an experiment after her aunt had sold her to Professor Donald Kelt. While he was able to talk her out of committing suicide to atone for accidently causing several deaths, the Doctor was then confronted by Kelt, who tried to threaten Imogen into further collaborating with him, only for her to kill him once he threatened her. With this final kill fully releasing her pent up rage, Imogen was convinced by the Doctor to use her new mental powers to help research teams to find cures for mental disorders. (PROSE: Artificial Intelligence)

When the TARDIS materialised on Psionosphere, the Doctor and Nyssa were caught in a psychic illusion generated by Maya to keep her company. However, the Doctor was able to escape with Nyssa by tricking Maya into thinking he was still with her, thus causing Maya to create an illusion of the Doctor. (PROSE: Confabula)

The Stockbridge ordeal
After he parted with Nyssa so she could undertake a solo expedition to 13th century Rhodes, (AUDIO: Renaissance of the Daleks) 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 Celestial 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.

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)

The Doctor travelled to the tomb of Qin Shi Huangdi in Xi'an and rescued Edward Grainger from a plane crash. Taking Edward aboard the TARDIS, the Doctor investigated the tomb and discovered it was guarded by a thousand terracotta warriors. Trekking through the tomb, the Doctor and his three friends fought thousands of enraged ghosts, which included Edward's dead crew. The Doctor used a sonic wave to defeat the ghosts, but was forced to wipe the mind of Edward's love interest, Mai Ling. (PROSE: Falling from Xi'an)

Reunited with Nyssa
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. He discovered that the inhabitants of the planet had used the Witch Guards to defend themselves. (AUDIO: Heroes of Sontar)

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. He and Nyssa encountered the Morass who were the castle's security system. He worked out that the Morass were programmed to protect the treasure of the planet, which was Turlough and Deela, not jewels. (AUDIO: Kiss of Death)

Whilst the TARDIS was calibrating the time circuits, the Doctor decided to take his companions to the middle ages, but ended up landing in 1983. He encountered a set of journalists and people from the Home Office searching the caves. Discovering a set of genetically engineered rats created by Christopher Wallace, he planned to take the rats to a planet away from the humans, but he realised that this wouldn't work, and the only solution was to use the punishment solution to de-evolve the rats, and let Wallace do this. (AUDIO: Rat Trap)

After landing in Calcutta on 31 December 1926, the Doctor and his companions joined an expedition to locate the fabled Emerald Tiger. During this adventure, Nyssa regained her youth again. (AUDIO: The Emerald Tiger) Then they landed on the Eight slash Q Panenka comet in 2329, where they met a crew of a space freighter. (AUDIO: The Jupiter Conjunction)

Attempting to get to Tegan's father's farm in the 1980s on her request, the TARDIS encountered a Zygma beam which took Nyssa and Turlough from the console room. The Doctor traced them to Brisbane in the 51st century. He was captured and taken to Findecker and was then tortured. The Doctor told Findecker that his experiments would never work as intended. He later had to rescue Nysa from Magnus Greel. (AUDIO: The Butcher of Brisbane)

The Doctor and friends landed in Ambermouth in 2013, where he encountered a strange set of crystals which were growing on the local wildlife. He discovered that another piece of Eldrad was on the Earth and that Mulkris was sent to find all of his parts. After taking Charlie Gibbs to Kastria, he discovered that the previous version of Eldrad had survived but then Mulkris proceeded to kill him. (AUDIO: Eldrad Must Die!)

Landing at the University of Frodsham in 1983, he encountered Philippa Stone who had created a primitive time machine which sent Tegan and John Bleak back to the year 918. He went after her using the TARDIS to get them back. (AUDIO: The Lady of Mercia)

The Doctor, Nyssa, Tegan and Turlough were forced to land on Valderon in 3556, where they encountered a penal colony. They learnt that their arrival was foretold by Sibor's chronoscope, which the Doctor later learnt was his first TARDIS, who wanted to punish him. He also met Nyssa's son Adric Traken. (AUDIO: Prisoners of Fate)

Trapped in E-Space
Trying to get Nyssa back to her children, the TARDIS located a CVE landing in E-Space back on Alzarius. He learnt that Adric had programmed the TARDIS to do this. On Alzarius, they encountered a set of Alzarians who were investigating the Marshman to learn more about themselves. He discovered Pik Solus had stolen a critical part of the TARDIS. (AUDIO: Mistfall) He traced Pik to Isenfel and managed to pilot the damaged TARDIS without too much problem. He learnt from Balancer Skaarsgard that the planet was an experiment to keep balance and maintain equilibrium through culling the population to keep energy and entropy constant. He realised that this was to simulate what was happening to E-Space. He lost Tegan to a set of pirates who kidnapped her. (AUDIO: Equilibrium) Managing to track Tegan to Apollyon, where the TARDIS lost all its power, the TARDIS crew discovered that entropy was setting in on the planet and that the people were trying to escape the collapse of the universe using Pallister's machine, which was powered by living beings. Nyssa decided to use herself as the power source to get the Doctor, Tegan, and Turlough home. Nyssa became trapped in the mini-universe when the CVE linking it and N-Space was sealed permanently. The Doctor then immediately went to see Nyssa's son Adric to tell him what happened. (AUDIO: The Entropy Plague)

Joined by Kamelion
The TARDIS arrived on 13th century Earth, where the Doctor met King John, despite history recording the King was in London on that date. 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. (TV: The King's Demons) Kamelion preferred to remain in the TARDIS for fear of being taken over by a stronger personality and used against the Doctor. (PROSE: The Crystal Bucephalus)

While travelling through space, the TARDIS was penetrated by a Phoenix, attempting to gain control of the main console room. However, the Doctor, Tegan, Turlough and Kamelion managed to access the secondary control room, and expel the Phoenix into the Time Vortex. (PROSE: The Bird of Fire)

While attending the grand opening gala of Professor Vittorio Levi's museum dedicated to the preservation of Earth's art and antiquities at a space station in orbit around Earth, Tegan was again overtaken by the Mara due to Levi's speech triggering her memories of it. Using Tegan's subconscious to gain a psychic hold on Kamelion, transforming him a Medusa-like serpent with Tegan's face, the Mara began turning the party-goers into stone. However, the Doctor defeated the Mara by having Tegan face it, forcing the Mara to relinquish its control of Kamelion when confronted with its own image. (PROSE: Mark of the Medusa)

When he asked for Kamelion's help in restoring the console, the TARDIS crashed into Orna's ship. The Doctor later had to pilot half the ship into landing when the power started failing. In the crash, he became paralysed but Turlough thought he had broken his back. He used a hover sled to get around, and used it to save Turlough when he fell of a cliff. He then got Turlough to pilot the TARDIS. He thought that Tegan was in control of Kamelion because of her strong will. He worked out that Tegan's wounds were healed by nanites in the stream, and hoped they could cure him. The guardian of the spring tried to stop him so that the secret of the spring would remain, but the Doctor was able to convince the guardian to heal him by arguing that if he died here his enemies would all come to the spring to celebrate. (AUDIO: Devil in the Mist)

The Doctor tried to take his friends to New York for a holiday, but when they materialised in York, Kamelion again fell victim to an alien threat when an other-dimensional entity who termed herself "the Hostess" managed to take remote control of him, forcing him to gather humans to collect power sources for her weapons. Tegan and Turlough were eventually forced to take part in the game, but the Doctor was able to disrupt the entity's control of Kamelion, forcing the Hostess to return to her dimension and be punished by her people for her actions. (AUDIO: Power Game)

As they left York, the TARDIS received a signal from Kamelion's own home planet, drawing him back along with others of his kind. After they followed the signal to a deserted world, the Doctor learned that Kamelion's original designers had been the centre of a vast empire, after the native Kamile uploaded their minds to the Locus when their planet suffered an environmental catastrophe that made it impossible to sustain life, using the Kamelion as a means of remotely enforcing their will on other worlds (the Doctor noted that this didn't match The Master's original description of Kamelion's history, but Kamelion observed that The Master was a notorious liar). Eventually, the Kamile within the Locus came together as four distinct factions that were essentially amalgamations of the original individual personas uploaded into it, titling themselves Authority, Liberty, Harmony and Chaos, with these factions eventually coming into conflict in a day-long war that involved their entire empire and its artificial intelligences, leaving Chaos trapped on that world. Chaos tried to use Kamelion to take control of the TARDIS, but Kamelion retained just enough control of himself to stop his body being used to harm his friends, allowing the Doctor, Tegan and Turlough to thwart Chaos's attempt to change history and then trap him in a secondary console room in the TARDIS before transferring Chaos back into the Locus. Despite Chaos's final defeat, Kamelion initially requested that he be abandoned on that planet so that he couldn't hurt anyone else, only accepting a compromise where he would remain in an isolated room in the TARDIS, trying to protect himself from being used by others against his friends. (AUDIO: The Kamelion Empire)

The Game of Rassilon
The Doctor took Tegan and Turlough to the Eye of Orion for a rest, (TV: The Five Doctors) and sent a message to River to ask if she wanted to join them. (AUDIO: Expiry Dating) However, all four of the Doctor's previous lives were being taken out of his timestream, and he began to fade away. Having his TARDIS forced to the Death Zone on Gallifrey, the Doctor stabilised thanks to the presence of his first incarnation, along with his granddaughter, Susan Foreman.

After encountering the Master and CyberNeomorphs in the Death Zone, the Doctor returned to the Capital, where he learnt President was trying to gain Rassilon's secret of immortality; he used the Doctors and his companions to clear the way past traps, even hiring the Master to assist him. With the help of his previous incarnations, the Doctor tricked Borusa into falling for Rassilon's final trap. After this, he instructed Rassilon to return his past selves and companions to their original times.

Though appointed Lord President after Borusa's downfall, the Doctor immediately decided to go "on the run" from the Time Lords in his TARDIS. (TV: The Five Doctors) As he returned to the Eye of Orion, a Raston Warrior Robot was sent by the Time Lords to eliminate the Doctor, due to his eighth incarnation visiting his past lives to regain his missing memories. As the robot attacked whatever moved, both Doctors approached it from different directions, confusing it to the point of self-destruction. (PROSE: The Eight Doctors)

Reminders of the past
While Kamelion was shapeshifting for Tegan and Turlough, he began to behave erratically and sent the TARDIS into a spasm when he interfaced with the telepathic circuits, but the Doctor was to separate him from the console before disaster could strike. Realising that Kamelion had been overwhelmed by the sheer influx of unquantifiable data from Tegan and Turlough's experiences, the Doctor built him a casket that would shield him from the data he couldn't process properly. (PROSE: Qualia)

While answering a distress signal from a cargo ship, the Doctor and Tegan were captured by the Sontarans to force Turlough to pilot a fighter craft against Lieutenant Braast as a rite of initiation for Braast. While Turlough fought Braast, the Doctor was able to remotely override the controls of Braast's ship, and sent him to his superiors in disgrace. (PROSE: Sontar's Little Helpers)

The Doctor received news that the Master had died and, alongside Tegan and Turlough, attended his funeral in an Earth nursing home where he had spent his final days. However, he discovered he had been lured into a trap by his enemy; the Master had faked his own death to steal the Doctor's remaining regenerations, as the Time Lords had taken away his current body. But the Doctor was saved by Turlough, and the Master's plan was foiled. (PROSE: The Velvet Dark)

After leaving the TARDIS without Tegan and Turlough, the Doctor received a warning from Vansell to leave immediately, but was locked out of the TARDIS. Along with a girl named Helen, the Doctor was caught by U-Boat captain Walther Schwieger, and the Time Lords almost assassinated him via a crewmember, but Helen saved him by shooting the crewmember. 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)

The Doctor, Tegan and Turlough landed on moon of Verbatim Six, where a set of Novelisors latched onto them. On their next trip they encountered the Ringpull, and the Doctor had to negotiate for Turlough's release when Turlough committed blasphemy according to the people behind the Ringpull. (AUDIO: Ringpullworld)

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. Despite his attempts to convince them otherwise, the Doctor was forced to use hexachromite gas against the reptilian life forms to stop them, and while successfully performing the abort procedure for the missile launch, failed to save any humans inside the base. (TV: Warriors of the Deep)

The Doctor landed the TARDIS in Little Hodcombe in 1984 to meet Tegan's grandfather, Andrew Verney. While in Little Hodcombe, the Doctor discovered a being called the Malus had been feeding off psychic energy generated by the negative emotions caused by the war games being held there, and was being assisted by Sir George Hutchinson. However, the Doctor managed to defeat the Malus and Hutchinson with the help of a schoolteacher called Jane Hampden and Will Chandler from Little Hodcombe in 1643, who was removed from his time by the Malus. (TV: The Awakening)

Returning Will home
Fulfilling his promise, the Doctor and Jane tried to take Will back to 1643. Soon after leaving Little Hodcombe, the Doctor, Jane and Will encountered a race of giant lizards. The Doctor succeeded in returning Will home after about a month of trying. (PROSE: The King of Terror) Then, with Jane's help, he acquired a place on the board of governors at Hexen Bridge School so that he could keep an eye on the area. (PROSE: The Hollow Men)

Continued adventures with Tegan and Turlough
During Christmas, the Doctor took Tegan and Turlough shopping in Oxford Street. There, they ran into trouble with the local police. (PROSE: Last Minute Shopping) They later spent Christmas with Iris Wildthyme. (PROSE: The Scarlet Empress)

In 1st century England, the Doctor met Ffion, a druid soothsayer, after she saved Tegan from being attacked by Romans. He became embroiled in the battle between Druids and Romans and witnessed many Druid slaughters. However, he managed to save Ffion and his friends by instructing Kamelion to disguise himself as a Roman soldier. Saddened by the deaths, the Doctor reluctantly stopped Ffion from wiping out of the Romans as it would change history. (PROSE: The Fall of the Druids)

While holidaying at Smithwood Manor, the Doctor was playing a game of cricket when he encountered the Judoon, who had come to Earth to retrieve the Eye of Akasha, which the Doctor had. The Doctor was willing to hand the Eye over to them, but the Judoon immediately threatened Tegan's life and demanded the Eye from the Doctor. Upset that his friends were being threatened unnecessarily, the Doctor pretended to hand over the Eye, but switched it out with a cricket ball. Due to the two items looking similar, the Judoon assumed the item had simply changed molecular properties and left. (COMIC: The Forgotten)

River Song finally responded to the Doctor's messages and persuaded him to steal something for her. The Doctor obeyed, and unknowingly robbed his tenth incarnation of a forged Scroll of the Last Days. River then drugged him to make him forget what had happened. (AUDIO: Expiry Dating)

Solo adventures with Tegan
The TARDIS was torn apart by the Tractators after being pulled to the planet Frontios. These aliens were stranded on the planet and needed wreckage to make a functional ship. The Doctor tricked them into rebuilding the TARDIS, with their leader, the Gravis, inside, separating him from the rest of the Tractators and leaving them without their hive mind. (TV: Frontios)

While attempting to transport the Gravis to Kolkokron with Tegan, the Doctor crashed on the planet Artaris, where he met Lord Grayvorn, who was on a quest to look for and artefact called "the Relic". After arriving in a nunnery to get the maps to find the Relic, the Doctor encountered Iris Wildthyme, who accompanied them on their quest. When they discovered the location of the Relic, they found that it was being guarded by zombies that were resurrected by the Relic. However, they managed to steal the Relic and arrived back at the convent. Upon their return to the convent, Grayvorn and the Mother Superior fought over the Relic and fell off the convent bell tower to their apparent deaths. The Relic was lost again. (AUDIO: Excelis Dawns) After an inadvertent stop on Queth, (PROSE: Life After Queth) the Doctor and Tegan left the Gravis on a barren, rocky planet called Kolkokron. (TV: Frontios)

After leaving the Gravis on Kolkokron, the Doctor and Tegan decided that, rather than heading straight to Frontios to pick up Turlough, they would see the destruction of Earth in Africa, where they meet Susha and Cuther, who had been among those left on Earth to die when the Arks left. Leaving just before the end, the Doctor and Tegan watched the Earth's destruction on the TARDIS scanner. (PROSE: Perfect Day)

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)

The Doctor and Tegan visited Camelot, where they met King Arthur and discovered the Master was disguising himself as Merlin, in a plot to help Mordred successfully kill Arthur at the Battle of Camlaan. The Doctor assisted Arthur in forming the Knights of the Round Table to protect Camelot against dark forces and broke the Master's hold over him, having him banished from the kingdom afterwards. (PROSE: The Creation of Camelot) The Doctor and Tegan also had "a particularly lively visit" to the planet Nocturne. (AUDIO: Nocturne)

The Doctor took Tegan back in time to kill a baby destined to grow up into a dictator who would doom the Earth. However, he was unable to go through with the act, and left. (PROSE: Categorical Imperative)

The Doctor and Tegan 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?)

The Doctor helped Konis to build a new world for his people but lost his memory once inside. After discovering the truth of Konis' world, Tegan arrived and told him how to get out. He worked out that Volos had created the Vodyani. He tricked the Vodyani back into the reality engine and created a copy of himself to help Volos out of the machine. (AUDIO: Nightmare Country)

Final adventures with Tegan
After many detours, the Doctor and Tegan collected Turlough from Frontios and became caught in a time corridor. (TV: Frontios) Escaping from the time corridor, the TARDIS crew found themselves in Snowdonia, Wales during a UNIT training excerise where they seemingly reunite with the Brigadier. Uncovering a plot orchestrated by the Autons and the Master, who had disguised himself as the Brigadier, the Doctor was captured to be used as a "keystone" for an ancient Vortex Driller.

He was later rescued by Turlough and the real Brigadier, who had encountered an earlier version of the Doctor inhabiting an Auton duplicate body. They escaped back to Snowdonia through a bridge connecting it to the Driller, which proceeded to close and leaving the Doctor's TARDIS as an empty shell. The Doctor proceeded to use the Master's TARDIS, having discovered it disguised as a circus tent earlier on, to track down where the Driller is heading: Saturn.

Arriving back onboard the Vortex Driller, the Doctor witnessed the Nestene Consciousness attempt to take control of the Driller. Contacted by Kamelion and his earlier self, now a psychic projection, the Doctor headed off alongside Tegan in the Master's TARDIS to help forumlate a plan of stopping the Consciousness. He didn't recall leaping through his personal timeline, nor did Tegan remember him collapsing after departing the Urbankan spaceship, leading to the Doctor to realise that his earlier self was actually a disintegrating splinter.

After successfully defeating the Consciousness, the Doctor told his splinter that he cannot return to his point of origin, especially with the knowledge of Adric's death. Instead, he watched as the splinter made "one last adventure" into the future where he would then fade away. With the TARDIS interior reinstated by Kamelion, the TARDIS crew departed from Wales, only to be targeted by another time corridor. (AUDIO: The Auton Infinity)

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
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)

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)

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)

In Brazil in 2080, the Doctor and Turlough encountered a band of Loups-garoux whose leader, Ileana de Santos, became attracted to the Doctor. After Pieter Stubbe forcibly took over the group to have Ileana as his mate and set them against humans, the Doctor challenged him. After halting the group's rampage in Rio de Janeiro by planting doubts about Stubbe's leadership, the Doctor tricked him into entering the TARDIS, taking him far away from Earth which caused him to die. Afterwards he said a private farwell to Ileana. (AUDIO: Loups-Garoux)

Travelling into the past to witness the first encounter of the Neanderthal and Cro-Magnons, the Doctor set up a camp and allowed Turlough to leave in his TARDIS, waiting six months until they 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 planned to show Turlough a beautiful place to paint but went to the wrong place. They decided to explore this location and learnt that the place stored memories. They learnt that the Hux was behind this. (AUDIO: The Memory Bank) On a second attempt, they travelled to Vadhoc, where they encountered Grayling Frimlish. Diamon welcomed them to her village. The Doctor was accused of being a story teller who branded people a witch. (AUDIO: The Last Fairy Tale) After defeating the Bratanian Shroud who possessed Kat Gunnarsdottir, her wife Lara Jensen thought the Doctor was robbing the place. Inspector Jill Sveinsdóttir arrested him and the Doctor thought he was being framed. He discovered that Turlough had been possessed by the Shroud and defeated it by turning off the city's data flow. (AUDIO: Repeat Offender) Wanting to explore an unmapped planet, the Doctor and Turlough discovered an agrarian society. He helped the Waywalker in her endeavours to get to a coming of age ceremony. (AUDIO: The Becoming)

The Doctor and Turlough landed on Testament when the human empire was centred there. He was delighted to eventually visit there but was concerned when noone knew how the power was generated. He learnt from Katherine Ellison that she predicted the energy increase would cause an explosion. He found it appalling that the humans were exploiting the Blinovitch Limitation Effect as an energy source. After the explosion, Horobin thought the Doctor was a saboteur and didn't think that he was right about the explosion. He was told that Turlough had died in the explosion by Violet Hardaker. He wanted the planet imploded to stop the explosion and tried to explain this to the prime minister. He wasn't sure that he wanted to go through with the explosion as it would kill a culture. (AUDIO: The Blazing Hour)

On a visit to Syria, the Doctor and Turlough were pursued by John Quarrington for information about a lost city. Ibrahim rescued him before being shot.

He was then abducted by Vakrass. He took him and Turlough to his base of operations near the fabled location of the lost moon of Botoya. The Doctor encountered his Sixth and Eighth incarnations. On Vakrass’ request, the Doctors travelled to the lost moon of Gallifrey, via a portal formed by the medallions each Doctor had found, to find Gostak. The Doctors learned that the moon was a complex temporal manipulation device that Gostak intended to use to undo the last few thousand millennia to re-establish the Time Lords as a vast empire. The Doctors refused to help his plans, with Gostak's efforts to force their aid being cut short as the Doctors turned the moon's power against itself, aided by the arrival of the Seventh Doctor with a control rod for the moon's system.

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 proper adventure together, the Doctor and Peri led a rebellion on the planet N'Tia, and were hunted by service robots.

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)

As they had distracted his pursuers, the thief prepared to leave the Doctor and Peri unharmed, but was attacked by a burglar, who took the gemstone. With his life-support unit damaged, the thief quickly died, and the burglar was frozen to death by the gemstone, despite the Doctor's attempt to warn him. (PROSE: Hot Ice)

After arriving 1880s California, the Doctor and Peri learnt of the Fountain of Youth being nearby, and found that was searching for it to heal his burns from Sarn.

As the dinosaurs quickly died again, the Doctor destroyed the cavern to keep the Fountain of Youth secure. (PROSE: A Town Called Eternity)

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 effect 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)

The Doctor subsequently resolved to arrange a new Overseer's appointment and fulfill Tog's wishes to put his insane timeline out of its misery. (AUDIO: The Axis of Insanity)

The Doctor took Peri and Erimem to 1917 Tibet so he could play in a cricket match.

The Doctor found her on the planet and took her into the TARDIS, where they travelled together for a year-and-a-half, when 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 returned her to her interview. (PROSE: Time on a Vine)

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
Shortly after Erimem's departure, the Doctor and Peri went on a holiday to Grallista Social.

While Peri went exploring, the Doctor traced the radiation to the church crypt, where Father Hemmings was housing four dead alien bodies, believing them to be fallen angels in need of absolution. When Peri arrived, having learnt that Hemmings had lost his lover and unborn baby and refused to give them their Last Rites, she convinced him to let the Doctor dispose of the bodies by forgiving him for his sins. (PROSE: The Canvey Angels)

Seeing that Zarl was bragging on a social media site about his plans on Earth, the Doctor and Peri travelled to 2009 Los Angeles to stop him.

"Thank you, all of you. Goodbye."

- The Fifth Doctor's last words

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.

(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.

 * River Song met the Fifth Doctor, noting his obsession with the Eye of Harmony, which she believed was a night club. She had his memory wiped with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)
 * The Fifth Doctor had numerous encounters with Darzil Carlisle, assisting him with negotiations for dozens of peace treaties across the galaxy. These occasions earned Carlisle the reputation as a notorious peace negotiator, and as a symbol of galactic peace. (AUDIO: The Game)
 * UNIT contacted the Fifth Doctor to inform him that his TARDIS had been discovered encased in rock at Pompeii during an archaeological excavation in 1980. At the time, the Fifth Doctor's TARDIS was located in Hyde Park. (AUDIO: The Fires of Vulcan)
 * The Fifth Doctor won the cricket league cup in Cheldon Bonniface. (PROSE: Happy Endings)
 * On a Thursday in the summer of 1966, the Fifth Doctor visited Andy Warhol to have his face added to a portrait of eleven incarnations of the Doctor. (PROSE: The War of Art; COMIC: The Girl Who Loved Doctor Who)
 * The Doctor and Tegan once fought off two Grey Dalek together. (PROSE: A Brief History of the Daleks)

Alternate timelines
In one timeline, the Doctor was able to save Adric. In another 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)

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)

Averted timelines
When the Cybermen allied with 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)

Undone events
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)

Splintered into his future
In a splintered timeline, (AUDIO: The Auton Infinity) after departing from the Urbankan spaceship, the Doctor passed out almost immediately after Nyssa collapsed, and found himself pulled along his own timeline. He first ended up in the body of his future self, at a point where Adric had "left" the TARDIS and Tegan had recently resumed her travels with him and Nyssa. The Doctor soon discovered the TARDIS had jumped back along her temporal vector, looking for a stable time track, and he believed he has done the same thing. (AUDIO: Secrets of Telos)

Next, he found himself in the body of his "near-future" self, with the TARDIS having just arrived in 9th century Iceland. He is relieved to see Adric again and, during an encounter with Ice Warriors, confides in him about his recent "time shifting" as he had done so with the future Nyssa and Tegan. After defeating the Ice Warriors, the Doctor felt himself be pulled along his timeline once again (AUDIO: God of War) and woke up in a cell next to the Brigadier, who recognised his current incarnation. He then reunited with Tegan, explaining how he had time shifted again, which becomes clear when he fails to recognise Turlough.

The Doctor is soon briefed on the Autons and the Master's scheme and, during an encounter with a Nestene, discovered that he is not in the body of his future self, but rather an Auton duplicate. He is later confronted by the Master, who initially believed him to merely be a convincing double, but soon realised he can use the "Auton Doctor" as a replacement "keystone" for piloting the Vortex Driller after the "future Doctor" escapes. Due to the Doctor being in an Auton body, the process did not work correctly and caused the "Auton Doctor" to be displaced once again, only this time he ended up as a psychic projection within his TARDIS next to another future companion called Kamelion.

After making contact with his future self, the Doctor helped formulate a plan to stop the Nestene Consciousness taking control of the Driller. After successfully defeating the Consciousness, it is revealed that the displaced Doctor was actually a disintegrating splinter and could no longer return to his intial point of origin. The splinter was allowed to make one last trip into the future, where he met Peri and positively reflected on his future before fading away. (AUDIO: The Auton Infinity)

Personality
Practicing good manners in the hopes that people would give him "the benefit of the doubt" he was non-hostile and share their resources, (TV: Kinda, Snakedance) the Fifth Doctor saw "small beautiful events" as being "what life [was] all about", (TV: Earthshock) and would go against the rules to offer a helping hand wherever he found someone in need, (TV: Earthshock, Terminus, Frontios) being willing to make enormous personal sacrifices simply to keep his friends safe and liberate others from suffering, (TV: Mawdryn Undead, The Caves of Androzani) and would try to stop and help others with their mundane troubles while in the middle of dealing with greater threats. (TV: Arc of Infinity)

He could see the qualities in others and sought to bring out their potential. (TV: Castrovalva) He was even 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) However, he tried to avoid confrontation with his companions when they were upset with him, opting to ignore them until they had calmed down. (TV: The Visitation, Earthshock) According to Tegan Jovanka, he would often "take everything in [his] stride", (TV: The King's Demons) and downplayed how events went when explaining them to people. (TV: The Visitation)

However, the Doctor's boyish appearance, nervous energy, and charm all hid the fact that he was a Time Lord of great power and knowledge. (TV: Snakedance, Mawdryn Undead, Enlightenment) He was not without an ego, happily saying when he was good at a subject after someone admitted they were not, (TV: Four to Doomsday) and being overly confident when he knew how good he was at something. (TV: The Visitation) He would put on a false smile to lure his opponents into underestimating him until he could think his way out of a situation, (TV: Four to Doomsday) and was not afraid to antagonise his enemies as an act of defiance, (TV: Earthshock, The Caves of Androzani) and declare his intent to interfere in their plans. (TV: Arc of Infinity)

Originally, the Fifth Doctor acted like a child excited to see new discoveries and foreign places. (TV: Four to Doomsday, Kinda) However, after the death of Adric, (TV:  Earthshock) he acted more openly stressed out and passive to harsh developments. (TV: Arc of Infinity, Snakedance, Terminus) As he was more exposed to the growing violence he encountered in his travels, the Doctor became more malaise to the carnage he saw throughout the universe, (TV: Warriors of the Deep, Frontios, Resurrection of the Daleks, The Caves of Androzani) to the point that he alienated Tegan from the TARDIS. (TV: Resurrection of the Daleks) The sudden betrayals he also endured (TV: Arc of Infinity, The Five Doctors) caused the Doctor to develop trust issues, to the point that he threatened to cut ties with Turlough if he dared to deceive him. (TV: Planet of Fire)

No longer trying to be "old and grumpy and important" like his previous incarnations, (TV: Time Crash) though worried his youthful body would not be taken seriously, (AUDIO: Smoke and Mirrors) the Fifth Doctor was very open and vulnerable in his naivety, trying to focus on seeing the friendlier side of the universe by giving aliens the benefit of the doubt towards their intentions, opting to "look on the bright side" when things looked grim. (TV: Four to Doomsday, The Visitation, Warriors of the Deep) He gained trust by proving himself with his honesty instead of using his vast experience as an excuse to take charge. (TV: Black Orchid, Snakedance, The King's Demons, Warriors of the Deep) Indeed, he could easily fall into the thrall of those who had the strong command presence that he lacked. (TV: Earthshock, The Five Doctors, The Caves of Androzani) However, he would take charge in moments of intensity, (TV: Kinda, Frontios, Resurrection of the Daleks) and, while he needed a piece of the Great Crystal to face down the Mara, (TV: Snakedance) the Doctor could still call upon great willpower when the need arose. (TV: The King's Demons, Planet of Fire, Dimensions in Time)

Unlike his other incarnations, he would seek out the highest authority when he landed so as to make his case for cooperation, (TV: Warriors of the Deep) though his trouble with being assertive would often lead to him running afoul with local authorities and being arrested or imprisoned. (TV: Kinda, Black Orchid, Snakedance, The Caves of Androzani) He would particularly earn the ire of authoritative figures when his actions were mistaken for tomfoolery or treachery. (TV: Earthshock, The King's Demons)

His young appearance was reflected in the youthfulness of his companions, whom he treated akin to how a teacher would treat their schoolchildren, to the point of patronising them, (TV: Four to Doomsday, Snakedance, The Caves of Androzani) and would scold them severely when their failure to heed his instructions resulted in him being put at a disadvantage. (TV: Enlightenment)

He could also lose his temper when around someone who annoyed him, (TV: Time Crash) and was known to get impatient when pressed for time. (TV: Castrovalva, The Visitation, Arc of Infinity, Frontios) He was unafraid to point out how others were complicating matters with their pride (TV: Black Orchid, Earthshock) or apparent idiocy, (TV: Four to Doomsday, Mawdryn Undead, Time Crash) and would become particularly irked when he was being put to death as a scapegoat for others to avoid dealing with their problems when there were alternative solutions. (TV: Arc of Infinity, Frontios, The Caves of Androzani)

He was notably for his use of sarcasm, especially when simultaneously dealing with Tegan and Adric, (TV: The Visitation) and was proficient with puns. (TV: Four to Doomsday, Enlightenment, The Caves of Androzani) He also felt suited for settling down and starting a family. (AUDIO: Loups-Garoux, No Place Like Home, Winter)

Being highly curious and eager to learn and explore, the Fifth Doctor would often let his curiosity dictate his decision making, leaving him to being easily distracted and getting caught up in his own thoughts and musings, to the point where he got himself and others into trouble simply by not paying enough attention to his surroundings, even when he knew that such a mind-set was one of his flaws. (TV: Black Orchid, The Caves of Androzani)

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) often spending long periods of time playing the game, (TV: Black Orchid; PROSE: Happy Endings, Goth Opera; AUDIO: Autumn) 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 also liked "long walks", (TV: The Visitation) and having live audience participation in large shows. (AUDIO: Nekromanteia) 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)

He did not like earrings, (TV: Four to Doomsday) 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)

While he didn't "[feel] at home" on Gallifrey, (AUDIO: No Place Like Home) he did consider returning to his home planet as a retirement plan. (COMIC: The Tides of Time)

His drink of choice was lemonade with ice, (TV: Black Orchid) and he also liked tea, (TV: The Awakening) believing it to be one of the things about the universe he loved. (AUDIO: Omega) He took his tea with either two sugars (AUDIO: The Eternal Summer) or with milk and no sugar. (AUDIO: The Elite) He considered fresh chilled orange juice to be "one of the finest things about Earth". (PROSE: Fascination)

He also enjoyed jam, (AUDIO: Plague of the Daleks) kippers, and porridge. (PROSE: Empire of Death)

The Doctor thought that it was best to "learn by [his] mistakes", (TV: The Awakening) and 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) While he preferred to take risks alone, he conceded that "a risk shared [was] a risk doubled". (TV: Frontios)

Unwilling to accept that violence was "a universal way of life", (TV: Resurrection of the Daleks) the Fifth Doctor was disdainful towards needless deaths, (COMIC: In Their Nature) and tried his best to avoid using violence when "there [could] [be] another way", (TV: Warriors of the Deep, The Awakening) not even tolerating violence when it was being used to rescue him. (TV: Arc of Infinity) He was particularly furious when Peter Sandoz shot Miss Tremayne when she was threatening him with a knife, believing he could have talked her down. (AUDIO: Winter for the Adept) When he resorted to dubious actions, the Doctor had to reassure himself that his actions were done without choice, believing he could convince himself with enough repetition. (COMIC: Lunar Lagoon)

However, he did possess a dark side, gunning down foes when he deemed it necessary, (TV: Earthshock, Arc of Infinity, Warriors of the Deep, Resurrection of the Daleks) and not moving to save the Master from a fiery death, though was deeply upset by his part in it. (TV: Planet of Fire) He was also willing to physically slap someone to calm them down, (COMIC: Stars Fell on Stockbridge) and accepted a pistol from King Louis, but only so he would not contradict the king. (AUDIO: The Church and the Crown)

While he failed to execute Davros in cold blood, (TV: Resurrection of the Daleks) he did destroy Kamelion at the android's request. (TV: Planet of Fire) He also once shot the Master non-fatally in the chest to subdue him. (PROSE: A Town Called Eternity)

While his feelings were hurt when Adric called him "decidedly immature" when in comparison to his fourth incarnation, (TV: Earthshock) the Fifth Doctor showed off an immature and childish side when he went to great lengths to avoid doing something he personally did not want to do, coming up with every excuse he could to prevent himself from being forced into action. (TV: Earthshock, The Five Doctors) When Tegan voiced her unease with traveling with Kamelion, the Doctor pranked her by pretending to take her reluctance as a sign she didn't want to travel with him anymore, and even acted like he was going to return her home when he had instead set course for the Eye of Orion, just to tease her. (TV: The King's Demons)

The Doctor could fail to notice when his companions did not want to follow his instructions, (TV: Four to Doomsday) when they were trying to show off a new outfit to him, (TV: Snakedance, Enlightenment) or were not enjoying themselves in their adventures as much as he was, (TV: Resurrection of the Daleks) and he could be dismisses of people when his mind was focused elsewhere. (COMIC: Stars Fell on Stockbridge)

He also tried to find a positive approach to life, even if it was a delusional one, (AUDIO: Iterations of I) such as fixating on the idea that Mondas was 1950s Trafalgar Square, wilfully ignoring the mine carts and giant underground cavern overhead. (AUDIO: Spare Parts) When he and Nyssa were arrested for using future currency during the Jacobin era, the Doctor tried to console Nyssa by pointing out that they still used Earth-based coins. (AUDIO: Summer)

The Fifth Doctor identified himself as being open-minded, likening himself to Alice as he "[tried] to believe three impossible things before breakfast". As such, he was willing to give his enemies the benefit of the doubt, such as when he met the Master 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)

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 told Peri Brown 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 personified his conscience due to his strong sense of compassion. (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)

The Doctor was highly protective of his TARDIS, becoming particularly irritated when he thought Nyssa had been tampering with it, (TV: Time-Flight) and frustrated when he thought the Tenth Doctor had changed his console control room design. (TV: Time Crash)

Although they often argued with each other, the Doctor told Lady Adela Forster that Tegan Jovanka was "very dear" to him, (AUDIO: The Emerald Tiger) and also told Tegan that he "[couldn't] bear the thought of not having [her] around", (PROSE: Qualia) though he 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 [and] half patronising" looks. (AUDIO: Aquitaine)

The Fifth Doctor somewhat looked down on humanity for being "parochial", and "fly[ing] off the handle" when they did not get their wishes, (TV: The Visitation) and could become patronising when trying to correct someone who refused to listen to him. (TV: Snakedance) While he "always had a soft spot for Earth", (COMIC: 4-Dimensional Vistas) he openly questioned his fondness for the "pathetic humans" of the "miserable planet" Earth when they elected to kill "noble races" in the name of retribution, (TV: Warriors of the Deep) though conceded that England was "one of the last few civilised places left in the galaxy". (COMIC: The Stockbridge Horror)

The Fifth Doctor believed the Master to be "the most evil force in the universe". (TV: Castrovalva)

He viewed his fourth incarnation's hesitation at averting the creation of the Daleks to have been "a mistake". However, while he did not hesitate to destroy Daleks, he was unable to bring himself to kill Davros with a gun to his face, ultimately giving Davros time to escape. (TV: Resurrection of the Daleks)

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 a "feckless, frivolous dilettante" who was an inferior replacement to the Fourth Doctor. (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)

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) When the Eighth Doctor had a tarot card reading, the Fifth Doctor was identified as "the Star". (PROSE: The City of the Dead)

The Tremas Master believed that the Fifth Doctor was "the nice one [with] such charm, innocence, [and] naiveté", (GAME: Destiny of the Doctors) while the Reborn Master 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, (TV: The Caves of Androzani) even holding back his impending regeneration. (AUDIO: Winter) After he accidentally dropped half of the bat's milk remedy, the Doctor selflessly gave Peri all that remained of the antidote, saving her life at the cost of his own. (TV: The Caves of Androzani) Reaching out for aid in gathering his strength, (AUDIO: Winter) the Doctor felt comforted as he saw visuals of his past companions appearing before him. Though he was content to die, when he saw the face of the Master taunting him, the Doctor choose to survive with a regeneration so as to not let the Master have "the last laugh". (PROSE: The Caves of Androzani)

Habits and quirks
When needing to examine something, the Fifth Doctor would sometimes sport a pair of glasses. (TV: Castrovalva, Kinda, Frontios, Planet of Fire, Time Crash) While he claimed to need them due to a weakness in his right eye, (TV: Four to Doomsday) the Tenth Doctor confessed that these "brainy specs" only served to make his fifth incarnation look "a bit clever". (TV: Time Crash)

When not instructing people to follow him with an utterance of "come on", (TV: Four to Doomsday, The King's Demons, The Five Doctors, Resurrection of the Daleks) the Fifth Doctor would instead instruct someone to follow his lead by saying, "this way". (TV: Arc of Infinity, Snakedance, Terminus, Warriors of the Deep, Dimensions in Time)

To encourage others, the Doctor would tell them to have a "brave heart", especially with Tegan. (TV: Earthshock, Enlightenment, Warriors of the Deep, The Awakening) He was also known to say, "Sorry, must dash", especially when leaving in a hurry. (TV: Castrovalva, The Five Doctors)

He typically introduced himself with the greeting, "How do you do?". (TV: Earthshock, Terminus, Enlightenment, Frontios) When met with disappointment or adversity, he would utter a defeated, "oh, no". (TV: The Visitation, Mawdryn Undead, Terminus, Planet of Fire, Time Crash)

During his early days, the Fifth Doctor's voice was prone to becoming high pitched in moments of intensity, (TV: Castrovalva, Four to Doomsday, The Visitation, Earthshock) something that the Tenth Doctor found comradery in. (TV: Time Crash)

As rather stagnant incarnation, the Fifth Doctor would usually alternate between having his hands crossed behind his back or in his trouser pockets while flicking the long tails on his coat back, with it being extremely rare for him to go an entire adventure without doing either. (TV: Terminus, Dimensions in Time) He was also known to occasionally place his hands in his coat pockets instead. (TV: Kinda, The Visitation, Earthshock, The Caves of Androzani)

In a deviation from his stagnant posture, the Doctor would wring his hands together in a fidgety manner. (TV: Earthshock, Time-Flight, Arc of Infinity, Snakedance, Enlightenment, The Five Doctors, Warriors of the Deep, The Awakening, Frontios, Resurrection of the Daleks, The Caves of Androzani) However, he would interlock his fingers when sitting or crouching down, (TV: Four to Doomsday, Mawdryn Undead, Terminus, The Awakening, The Caves of Androzani) or when he was in thought. (TV: Arc of Infinity)

He crossed his arms when sulking (TV: Kinda, The Visitation, Earthshock ) or on the defensive, (TV: Terminus, The Awakening) and was prone to dramatic turns, which usually caused his hair to sway wildly. (TV: Castrovalva, Kinda, The Visitation, Time-Flight, Snakedance, Mawdryn Undead, Terminus, Enlightenment, The Five Doctors, Warriors of the Deep, The Awakening, Frontios, Resurrection of the Daleks)

When in a stressful situation, he would scratch the back of his head as he worked on how to deal with the crisis, (TV: Arc of Infinity, Enlightenment, Warriors of the Deep) and would chew on the digits of his hand when thinking. (TV: Castrovalva, Four to Doomsday, Kinda, Mawdryn Undead, The Awakening)

When gobsmacked, he had a tendency to stare with a slack-jawed look on his face, (TV: Kinda, Earthshock, Snakedance, Enlightenment, Warriors of the Deep) and would spread out his arms and look upwards to emphasis a point. (TV: Castrovalva, Earthshock, Snakedance)

The Fifth Doctor often delegated some decisions to the simple chance of a coin flip. (TV: Kinda, Time-Flight, Enlightenment, The Awakening)

Skills
While he preferred to use trickery to solve a problem, (TV: Frontios) the Fifth Doctor was still very capable of defending himself unarmed when pushed to physical confrontations. (TV: Kinda, The Visitation, Terminus, Warriors of the Deep) He retained the swordsmanship acumen of his predecessors, being able to best the Tremas Master in a duel, (TV: The King's Demons) and was also highly skilled at the sport of cricket, (TV: Black Orchid) being a "strong right arm bowler ". (AUDIO: The Council of Nicaea)

He was a proficient shot with a gun, even stating that he "never miss[ed]" his targets, (TV: The Visitation, Terminus, Resurrection of the Daleks) and also had the accuracy to throw a chair to jam a door, (TV: Terminus) as well as being 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)

He could perform basic surgery, even with limited equipment. (TV: Frontios)

The Doctor could determine the properties of something by taste alone, (TV: Castrovalva, The Visitation, Planet of Fire) and also possessed a heightened sense of smell, which he used to tell which time period he was in by smelling the air. (AUDIO: The Eye of the Scorpion)

He could play the harp. (TV: The Five Doctors)

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

Appearance
The Fifth Doctor was a young man. (TV: Logopolis) Peri Brown described him as having "fair blonde hair, blue eyes, and a sweet smile". (AUDIO: Peri and the Piscon Paradox)

While he initially thought his new face represented "the trouble with [the unpredictability of] regeneration", the Fifth Doctor soon thought himself to be "absolutely splendid". (TV: Castrovalva)

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, the Fifth Doctor's hair regularly changed length and colour. (PROSE: Cold Fusion) It was brown shortly after his regeneration, (TV: Logopolis) then quickly became platinum blonde. (TV: Castrovalva) On occasion, his hair had brown highlights (TV: Four to Doomsday)

His hair typically reached to the back of his neck. (TV: Castrovalva) While it was originally poofy with a long fringe, (TV: Logopolis) it quickly changed into a wavier style, (TV: Castrovalva) though his fringe was later shown as shorter and his hairstyle kept straight. (TV: Four to Doomsday)

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 beige frock coat with scarlet piping along the collar, lapels, sleeves, pockets and tails. Underneath his coat, the Doctor wore a cream cricket jumper with a crimson and black V-Neck pattern, and a white dress shirt with a red interior and embroidered cherry question marks on the collars. His trousers were a unique pattern of brown and beige stripes. He also wore white plimsolls and an ivory Panama hat that had a scarlet band with a black and white pattern. (TV: Castrovalva)

After his clothes were ruined by a Xaranti, (PROSE: Deep Blue) the Doctor changed to a French grey coat with a longer collar, a dress shirt with a green interior, trousers with thick orange lines, and a jumper with a pattern of thick red and black lines on the bottom, the V-Neck and sleeves. (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

Casting

 * After the popularity of Tom Baker's Fourth Doctor, it was decided that the fifth incarnation would be played by an actor who was already firmly established in the British public's mind.
 * Richard Griffiths was considered for the role, as was Iain Cuthbertson.
 * Peter Davison was eventually chosen to be the Fifth Doctor, 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.

Peter Davison's age

 * Only 29-years-old when cast, Peter Davison remained the "youngest Doctor" until the hiring of 26-year-old Matt Smith in 2009.
 * Ironically, when he reprised the role of the Fifth Doctor in Time Crash in 2007, Davison, then 56-years-old, was a year older than First Doctor actor William Hartnell was during the filming of An Unearthly Child.

Costume details

 * Davison agreed to wear a stick of celery on his lapel on the understanding that John Nathan-Turner 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, finding it deeply unpleasant when he was required to eat it during the recording of Castrovalva. (DCOM: Castrovalva)
 * Because no make-up artist seemed to particularly care about the length of Davison's hair throughout season 19, the Fifth Doctor's hair length varied between stories, as Davison had his hair cut short at the beginning of each season to accommodate other projects like All Creatures Great and Small that required his hair to be short, and the production team allowed him to grow it throughout each of his production blocks, despite the fact his serials were being recorded out of broadcast order. Davison would joke on DVD commentaries that "real fans" can tell the production order of episodes by the length of his hair.

Other matters

 * 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.
