Seventh Doctor

Originally a man with the demeanour of an eccentric, light-hearted buffoon, the Seventh Doctor darkened into a mysterious, cunning manipulator to combat the return of Fenric. Though he delighted in humorous reverie, it was only the surface layer of his true nature. Beneath, he was a Machiavellian genius of frightful calibre who could tactfully use his mind to manipulate almost any situation into reaching his favoured outcome. Despite this, he could also show profound warmth and affection to his companions, and built a strong bond with many of them.

Initially, the Seventh Doctor travelled with his predecessor's final companion, Melanie Bush. After several adventures with the new Doctor, she left to travel with Sabalom Glitz, prompting him to begin travelling with Ace, a troubled teenager from Earth in the 1980s. Treating her both as a protégé and initially as a pawn in Fenric's game, he did his best to help heal Ace's psychological wounds by helping her come to terms with her past misdeeds and fears, aiding her in maturing and supporting her in moments of difficulty. Although he initially planned to take Ace home, they ultimately travelled together for several years, only for their strong bond to grow increasingly strained as secrets and death tore them apart.

Following Ace's initial departure from the TARDIS, he became "champion" to the Eternal known as Time. Although he did many good deeds while under the title of Time's Champion, his manipulative ways and amoral decisions cost him dearly, leaving him questioning his actions and himself. The aftermath left him tired and saddened, and after reuniting with many old friends he eventually began a lonely retirement from plotting. Though wearisome, he decided he would return to Gallifrey when the Time Lords needed his assistance, but having grown complacent in his retirement, he let his guard down at the wrong time, and paid for it with his life.

After many years of schemes and manipulation, the Seventh Doctor regenerated in San Francisco on 31 December 1999, following Dr Grace Holloway's exploratory surgery on his gunshot wounds accidentally clogging a vein.

Foreshadowing
The Valeyard offered to tell the Sixth Doctor of his next incarnation, whom he claimed was filled with "plots and schemes," all to "win a game that was never his to win." (AUDIO: Trial of the Valeyard)

Regeneration
The Sixth Doctor attempted to avoid visiting the planet Lakertya while travelling with his companion, Mel, after he discovered an ominous source of radiation nearby. However, his future self, trapped inside the Matrix, sent him a psychic signal advising him to go to the planet regardless, as the Valeyard had previously implanted Nathemus inside his head without him knowing at the time, and, in this timeline, had succeeded in using them to replace all Time Lords with his own existence.

Upon approaching Lakertya, the TARDIS ran afoul of the radiation source: focused laser beams being fired from the Rani's TARDIS. Whilst this only caused Mel to pass out, the particular radiation the Rani had been weaponising was lethal to Time Lords. This exposure mortally wounded him, ensuring the removal of the Nathemus in regeneration or death. Having retroactively thwarted the Valeyard's plan, the Sixth Doctor feared he had reached his demise, but the persona of the Seventh Doctor manifested before him and confirmed that he would regenerate. His future self, now an anomaly within the Matrix, felt the timelines changing and was reassured. The Doctor's sixth persona dissolved into his seventh, both stating, "Our future is in safe hands." (AUDIO: The Brink of Death)

A separate account suggests that, after being sapped of Chronon energy whilst fighting the Lamprey, (PROSE: Spiral Scratch) the Sixth Doctor suffered a fatal head injury due to the buffeting of the TARDIS caused by the Rani's laser bombardment. (AUDIO: Zagreus)

Whilst the Rani bombarded his TARDIS with lasers, his regeneration began. After she invaded his TARDIS on the planet Lakertya, the final stage of regeneration commenced. (TV: Time and the Rani)

The Doctor grew to believe that the essence of his seventh incarnation had somehow caused his predecessor's regeneration in order to bring himself into being. (PROSE: Love and War, Head Games) However, he eventually dismissed this as a delusion brought about by an increasingly fragile and scared mind, realising that such a thing was impossible as all his incarnations were the same person rather than separate consciousnesses. (PROSE: The Room With No Doors)

Post-regeneration
After the laser attack, the TARDIS was caught in the Rani's tractor beam, and was forced to make a landing on Lakertya's surface. She then boarded it along with Urak, a Tetrap, who she instructed to leave Mel but take the Doctor to her laboratory. As Urak turned over the Doctor's body, his regeneration completed, his appearance solidifying, but he remained unconscious. Awakening in the Rani's lab, the Doctor immediately recognised the Rani, but was knocked out by Urak and injected with an amnesia-inducing drug, which allowed her to trick him into assisting her with her project by pretending to be Mel.

Upon regaining consciousness again, the Doctor decided to choose a new look, noting that his new incarnation had regained a sense of haute couture. Returning to work on the Rani's machine, the Doctor found what was wrong with it, but caught the Rani on her lies when the real Mel snuck into the lab and revealed her identity.

Escaping, the Doctor discovered that several geniuses from throughout time, including Einstein, had been captured to act as components of the Rani's "time brain." Forced to become the final component, the Doctor caused it backfire and explode under the strain of his new personality. Rescuing the captives, the Doctor took them back to their own times. (TV: Time and the Rani)

Bemoaning the loss of his predecessor's rainbow umbrella and the tartan scarf he chose for his new outfit, the Doctor went back to his wardrobe and obtained a new paisley scarf and whangee-handled umbrella. Taking the time to clean out the dimensionally transcendental pockets of his former self's patchwork coat, he sat down to sort the contents of several lifetimes, organising them into two piles, of what was useful and what was not. While doing so, he considered the consequences of regeneration, and assessed whether he was going to like his new body. (PROSE: The Useful Pile)

Travels with Mel
Shortly after leaving Lakertya, the Doctor dropped Mel off in London in 2007. (AUDIO: Unregenerate!) After reuniting with Frobisher, the pair prevented an Ice Warrior plot on the planet A-Lux, where they bid each other a final adieu. (COMIC: A Cold Day in Hell!)

Becoming a prisoner at "the Institute", the Doctor sent the TARDIS back to Mel without him, leaving a message telling her to investigate a strange mental asylum. Discovering that was it was in fact an institute run by the Celestial Intervention Agency, she was reunited with a seemingly insane Doctor. Helping to restore his mind and sanity, Mel aided the Doctor in uncovering the truth behind the Institute: the medics were conducting experiments on sentient life forms, attempting to graft TARDIS minds into their bodies. Horrified at their amoral stance, the Doctor restored the TARDIS consciousnesses to their physical bodies, and freed the inmates. (AUDIO: Unregenerate!)

Travelling to Paradise Towers so Mel could enjoy its swimming pool, the Doctor found that the staff and residents residing within the Towers had all become either anarchist Kangs, cannibalistic Rezzies or pompous Caretakers. Accused of being the "Great Architect" that built the Towers, he was nearly killed by the Chief Caretaker, who wanted the Tower to run the way he wanted. The real architect, Kroagnon, a madman who killed anyone who moved into his creations to keep them perfect, was still within the complex, and had been using the Cleaners to murder residents. As the Doctor and Mel investigated, Kroagnon became concerned, and transplanted his disembodied mind into the Chief, going on a murderous rampage through the complex. He was defeated when Pex, the only male resident, pushed him to his death down a lift shaft, sacrificing himself to prove his bravery. (TV: Paradise Towers)

The Doctor and Mel travelled to Pax Lucis, an English village occupied by Nazis during the Second World War. When a barrier cut the village off from the rest of the world, the Doctor discovered the Nazis had captured the Lightwanderer, a creature that fed on solar radiation. The Nazis plotted to create a barrier around the Earth, which would destroy the planet. The Doctor gained an ally in the Nazis' commander, Luther, who sacrificed himself by blowing up "the weapon," saving the planet. (PROSE: Special Weapons)

The pair then materialised aboard a ship which had been sabotaged and set to explode. Teleporting away in the nick of time, the Doctor and Mel, impersonating the murdered crew members they had encountered on the ship, found that they had arrived on Dark Space 8, a space station currently hosting the Intergalactic Song Contest. Discovering that the song contest was being used as a cover for secret peace talks between Golos and Angvia, they managed to prevent the terrorist Loozly from sabotaging the conference. (AUDIO: Bang-Bang-a-Boom!)

After meeting Emil Hartung in 1936 Cairo, (PROSE: Just War) the Doctor and Mel encountered the Quarks on the space yacht Pinto, and left in the TARDIS in search of leptonite crystals, a substance highly toxic to them. They arrived on the planet Puxatornee in the year 3090 where the inhabitants were struggling to live in peace with a race called the Slithergees who arrived there as refugees some 30 years ago, but were slowly taking over. The Doctor and Mel were forced by Stuart and Reed, two inhabitants, to travel back to 3060 to kill the president of Puxatornee before she could invite the Slithergees to stay. When they returned, history had changed so that the Slithergees went to war with the Puxatornees. The Doctor and Mel became separated with Stuart and Reed and captured, but realised that an alternative Mel and Doctor were due to land in the same place as them and quickly escaped back to their TARDIS and left.

Another Doctor and Mel landed successfully and were captured by this alternative history's Lt. Stuart and Reed and interrogated before the now non-existent history's Reed and Stuart arrived to help them escape, but were killed shortly afterwards. This history's Lt. Stuart and Reed arrived and forced the Doctor and Mel to take them back 30 years so that they could prevent the president's death and make peace with Slithergees. The Doctor and Mel took them back then to see their new history, which was the first version before he and this Mel showed up. Lt Stuart and Reed ordered the Doctor to take them back to yesterday to prevent their earlier selves from time travelling, but the Doctor couldn't as that history no longer existed. The Doctor worked out that an alternative version of himself and Mel were due to land any minute and took off in the TARDIS just as their earlier selves showed up. (AUDIO: Flip-Flop)


 * The events above form part of a time loop which the Doctor and Mel were able to escape. Although the Doctor presumably retained knowledge of both sets of events happening after they left Puxatornee due to his being a time-sensitive entity, it is unclear what, if anything at all, Mel was able to recall.

On an unforeseen vacation, the Doctor and Mel found themselves part of an alien expedition to 1959 to experience the Earth's rock 'n' roll years. The Doctor discovered that the last Chimeron queen, Delta, was amongst their party, hiding with her newborn from the vicious Bannermen, mercenaries set on genocide. After defeating the Bannermen by causing their leader to fall into his own trap, he bid goodbye to Delta, her daughter and a human, Billy, who had fallen in love with her, as they departed for the Chimeron hatchery. (TV: Delta and the Bannermen)

After visiting the planet Nocturne, (AUDIO: Nocturne) the pair travelled to Iceworld, where they joined Sabalom Glitz and Ace, a teenage girl from 1980s Earth, on a search to find a treasure guarded by the "dragon" living in the caverns. The group discovered that the dragon was in fact a biomechanoid tasked with guarding the Dragonfire, a power source sought by exiled criminal Kane to power Iceworld, his prison ship, and return to his home planet to get revenge. However, Kane committed suicide when the Doctor showed him his planet no longer existed and that there was no-one for Kane to enact vengeance upon. (TV: Dragonfire)

Realising that Ace had been deposited on Iceworld by his old foe Fenric (TV: The Curse of Fenric) and that he could no longer avoid his responsibilities to Time, the Doctor planted an idea in Mel's mind, encouraging her to stay with Glitz with the intention to put him on the right path, and to urge the Doctor to take Ace with him. (PROSE: Head Games) His manipulations were successful, and he gained a new companion, offering to take her home to Perivale "the long way round." (TV: Dragonfire)

Early travels with Ace
The Doctor returned to Shoreditch in November 1963 to take care of events he had set in motion during his first stay on Earth, retrieving something had left behind: the Hand of Omega. As the Doctor had anticipated, his mission was disrupted by two opposing factions of Daleks, placing him, Ace and the Counter Measures military in the crossfire of a Dalek civil war, prompting him to join forces with Counter Measures leaders Ian Gilmore and Rachel Jensen to end the civil war.

Discovering that Davros now lead the Imperial Daleks as their Emperor, the Doctor used the his fanatical desire to give the Daleks the power of time travel against them. After much goading, Davros used the Hand on Skaro's sun, believing that he could use it to create a new Eye of Harmony. However, the Doctor had deceived him: the stellar manipulator had been pre-programmed by the him, and turned the star supernova, seemingly destroying Skaro, before returning to destroy the Dalek command ship. The Hand then returned to Gallifrey, as programmed by the Doctor. With only the Supreme Dalek of the Renegade faction left to deal with, the Doctor managed to convince it to self-destruct as it no longer held a purpose. (TV: Remembrance of the Daleks)

The Doctor left Ace in the Great Rift Valley, while he made various preparations in London. (PROSE: Prelude: Birthright) When he returned, they travelled to Terra Alpha, where citizens were being executed by the Kandyman if they did not follow Helen A's happy dictatorship. Killing her beloved pet Stigorax in self-defense, the Doctor showed Helen A that true happiness could only exist if balanced with negative emotions like sadness. Leaving citizen Daisy K and visiting Blues musician Trevor Sigma to help restore order to Terra Alpha, the two friends departed. (TV: The Happiness Patrol)

While exploring the TARDIS, Ace came across a locked room containing a window that visualised Gallifrey during the Doctor's childhood, which the Doctor had bought in his second incarnation. Feeling that it served as nothing other than a reminder of the past that he could never see again, the Doctor set about sealing the room off. (PROSE: uPVC)

Arriving in 20th century Windsor, the Doctor found the Nemesis statue, which he sent off into space every twenty five years, had returned. Tired of the chaos it caused, the Doctor needed to find its bow and arrow for his plan to be rid of it for good. During his search, he encountered Lady Peinforte and the Cybermen. Pretending to comply with the Cyber-Leader's orders, the Doctor prepared to send the Nemesis statue straight into the Cyberfleet, prompting Peinforte to merge with it, before launching it into space, where it exploded, destroying the Cyberships. (TV: Silver Nemesis) During a trip back in time to see how Lady Peinforte got to the future, the Doctor discovered a chess board in her study, and realised that Fenric was responsible. (TV: The Curse of Fenric)

While travelling in the TARDIS, the Doctor received "junk mail" advertising the Psychic Circus. Deciding to attend, the pair discovered that the circus had been taken over by the Gods of Ragnarok, who were forcing the patrons to perform for them until they lost interest; once no longer amusing, they would be destroyed. The Doctor took the fight to their home dimension, where he performed for them; once out of tricks, he used a medallion to reflect a blast back at them, destroying the Gods. Their business concluded, the duo departed, leaving the sole-surviving troupe member Kingpin and werewolf-like Mags to rebuild the Psychic Circus. (TV: The Greatest Show in the Galaxy)

Travels alone
After leaving Ace in the Cretaceous period, (COMIC: Train-Flight) the Doctor took up residence at Ercildoune in Scotland in the 13th century, using it as a base from which to set out on various travels. (PROSE: Birthright)

Alone, the Doctor carried the Telphin life-seed to Earth (PROSE: Memorial) and visited Victorian London, where he saved Ernie Wright from being arrested for a murder he did not commit. (PROSE: Birthright)

The Doctor paid a visit to Michael Faraday in 1854, where he delivered the remains of the Special Weapons Dalek. Ulrik appeared, followed by several Daleks tracking him through time. The Doctor manipulated events so that Ulrik would time travel once more and sent the Daleks after him, knowing that his previous incarnation would defeat them. (AUDIO: The Four Doctors)

Trapped in the Determinant by along with his six previous incarnations, the Doctor was saved when the Graak defeated the Master, sacrificing all of its life force to free the trapped Doctors. (GAME: Destiny of the Doctors)

When the Charrl Queen Ch'tizz came to Ercildoune looking for the TARDIS, the Doctor departed for good, visiting the court of Elizabeth I and persuading her to send John Dee on a fool's errand. (PROSE: Birthright)

The Doctor decided to take a long overdue vacation to the planet of Ormelia, and materialised the TARDIS aboard a spaceship orbiting the planet. There he befriended a genetically reconstructed creature named Vilgreth, but discovered that his ship travelled through space by devouring planets, and was forced to stop him. (AUDIO: Last of the Titans)

Growing darker
The Doctor travelled to Mongolia during the Cretaceous period to pick up Ace. Whilst seeking her out, he encountered a pit of Dholes and an alien slave who had escaped from a nearby construction site. Ace arrived with a herd of assorted dinosaurs to trample the site, destroying it and freeing the slaves. (PROSE: Living in the Past)

Together again, Ace and the Doctor were forced to land in a pocket universe built on 23 November, 1963, where they began to see images of the past and future of the TARDIS, and encountered his previous incarnation and Peri, who had also been brought there. Investigating further, he discovered that a past incarnation of was also present, and found out that he was the one behind his TARDIS malfunctioning and him being brought there. The Master had planted a conceptual bomb inside the human Bob Dovie that would make a single thought inside his head a reality. When Bob had entered the Fifth Doctor's TARDIS, he uttered the words "this is impossible," causing the TARDIS to explode across its own timeline.

The Sixth Doctor was able to bring the eight versions of the Doctor brought there together using a dimensional stabiliser from the TARDIS owned by the Time Lord Straxus, and together the Doctors stopped the bomb from going off by showing Bob the inside of the TARDIS a year before, ensuring that he would not consider it impossible when he re-entered it in 1963. Afterwards, the First Doctor turned off the automatic distress actions which had brought all of the Doctors to the pocket dimension, triggering the TARDIS' destruction, making it so none of it had happened.

Plagued by a niggling feeling, he and Ace visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963. (AUDIO: The Light at the End)

Tracing a signal being broadcast from another universe, the Doctor re-encountered UNIT, and was reunited with his old friend the Brigadier. Becoming embroiled in an adventure involving the inhabitants of an alternate Earth who mistook him for Merlin, he took advantage of this, discovering that the sorceress Morgaine was waiting for a final battle with King Arthur. Realising that Arthur was dead, he informed Morgaine, preventing her from firing a nuclear missile by appealing to her sense of honour. (TV: Battlefield)

After the TARDIS was attacked by a Kryian missile, the Doctor found his ship was locked onto Christmas Eve. After spending Christmas in 1889 and 2023, he and Ace travelled to Eastern Africa in 3181 to fix the problem, where they helped humanity to recover from an alien invasion and restored their faith in Christmas. (PROSE: Instead of You)

After learning of Ace's guilt over burning down a "haunted" mansion, the Doctor brought her to the house a hundred years prior to its destruction. There they discovered found a dangerously mentally unstable entity called Light, who planned to escape its imprisonment and destroy the Earth simply because its inhabitants had evolved while it was trapped, rendering the exhaustive catalogue it had compiled centuries earlier worthless. Able to use Light's childish logic against it, the Doctor convinced it to destroy itself, as it had been evolving as well. The Doctor then explained to Ace that the reason she burned down the mansion because of the residual presence of Light, ending her guilt. (TV: Ghost Light)

Landing in a military base in 1943, the Doctor accidentally caused Ace to meet and interact with her grandmother and infant mother. After revealing to her that that he knew her arrival on Iceworld and Peinforte's time travelling had been arranged by Fenric, an evil entity he encountered before and trapped in another dimension, the Doctor discovered that it had managed to manipulate those who had come into contact with the flask which contained it, and witnessed its escape. Plagued a horde of Haemovores it set loose on the base, the pair discovered that the creatures were repelled by faith, and managed to engage Fenric in a final contest. Convincing the Ancient One, one of Fenric's Haemovore servants, to kill his host in revenge for trying to trick it into creating its own apocalyptic future, the Doctor was forced to break Ace's faith in him in order to allow it access to Fenric. Revealing this to her, the Doctor regained her trust. (TV: The Curse of Fenric)

After defeating Fenric, the Doctor attended a school reunion at Hexen Bridge, a school at which he was one of the governors. He was kidnapped by Jerak, the other half of the Malus war machine which he had defeated in his fifth incarnation. After being turned into a walking bomb and manipulated to perform tasks that brought misery to Jerak's enemies, the Doctor stopped Jerak's plan to poison the world's water supply with a chemical that would turn the human race into insane murderers, and Ace destroyed Jerak's gateway domain, destroying him. (PROSE: The Hollow Men)

Soon after, the Doctor took Ace home to Perivale, where they discovered that people had been disappearing, and strange, cat-like creatures called Kitlings were on the prowl. The Doctor soon discovered that the Master was trapped on the Cheetah World, and had become infected with the Cheetah virus. Planning to escape by bringing people there, allowing them to partially change into Cheetah People and then using them to travel back to Earth, the Master had kidnapped many of Ace's old friends and ultimately Ace herself. After saving Ace and her friends, the Doctor fought with the Master, but refused to continue when he saw that the destruction of the Cheetah World had begun. He returned to Earth, leaving the Master trapped on the exploding planet. (TV: Survival)

At some point, Ace told the Doctor about how, working as a waitress, she gave a man in a chicken costume a box of fries. The Doctor, knowing what the creature was, was privately amused by this. (PROSE: Anti-Matter with Fries)

The Doctor's original plan for Ace involved trying to shape her mind to the point that she would be able to attend the Time Lord Academy. His manipulation of her was ultimately for the benefit of Time Lord observers who were assessing her potential. The assessment took the form of a journey to Moscow and London in 1967, involving the Ice Warriors. Ultimately, however, she respectfully declined this academic opportunity and continued to travel with the Doctor. (AUDIO: Thin Ice)

Raine joins
The Doctor spent an undisclosed time visiting a young girl named Raine Creevy, who had had delivered in 1967, when she was a child, before travelling to her future. In 1989, she was now a skilled thief who he recruited to steal a sword for him while he sent Ace to Russia on a secret mission. He plotted to use the sword to ward off an alien incursion by a race called the Metatraxi. After the Metatraxi were defeated, the Doctor offered Raine the chance to travel in the TARDIS, which she accepted. (AUDIO: Crime of the Century)

The trio next arrived at Margrave University in 2001, where they prevented an animal rights activist named Scobie from loosing the Numlocks on Earth. Leaving Raine or a short time, (AUDIO: Animal) the Doctor and Ace were reunited with her whilst undercover on the Space Vessel Vancouver, where they again encountered the Metatraxi. (AUDIO: Earth Aid)

Investigating an apparent artificial intelligence created by Raymond Luthier known as the Canterbury AI, the Doctor, Ace and Raine tracked down a software developer named Gina Gulpin in order to hack it. Discovering that it was in fact a scam, the trio left Gina to expose Luthier. (PROSE: The Girl Who Stole the Stars)

Work to do
After Raine left, the Doctor next followed a distress signal to Prague, where he met Elizabeth Holub, the granddaughter of his former UNIT associate, Liz Shaw, and allied with her to stop a young girl called Napev, who had the ability to create whatever she wanted, from launching a series of vicious attacks on the city to avenge the death of her father. (PROSE: Fable Fusion)

The Doctor and Ace spent Christmas with wheelchair-bound David Merrison, whose family had disappeared. Investigating, the Doctor learnt that an alien creature was feeding on David's fear of being taken. Finding the creature's skull, he destroyed it, killing the creature, and located the Merrison family on a spaceship in another dimension. (PROSE: But Once a Year)

On a holiday to the seaside, Ace met a fortune-teller called Hiram White, who was seemingly able to see the future. Sceptical, the Doctor discovered that he was actually a psychic alien from Candram, Cramand's moon, who had developed an addiction to fake health pills. He offered to return him home, but he declined, instead seeking help to travel back in time to acquire more pills to sate his addiction. The Doctor respected Hiram's decision and allowed him to choose his own fate. (PROSE: One Card for the Curious)

The Doctor and Ace battled the Cybermen in the Blitz, (PROSE: Illegal Alien) before encountering the Valeyard in Victorian England. Posing as Jack the Ripper, he had been feeding the Dark Matrix with the energies of the women he killed. He launched an attack on all of the Doctor's lives, but the Seventh Doctor managed to shield himself, at the cost of his memories. Reduced to an amnesiac cardsharp called "Johnny," he eventually managed to regain his memory, and convinced the Dark Matrix that the Valeyard was using it. Confronting him, the Dark Matrix killed the Valeyard with a blast of energy. (PROSE: Matrix) Needing a holiday, the Doctor and Ace journeyed to Coralee where they encountered the Krill. (PROSE: Storm Harvest)

While in the TARDIS, Ace found some overdue library books which the Doctor realised were from the library on Kar-Charrat, prompting him to travel to the planet in order to return them. There the Doctor encountered an old friend, the chief librarian Elgin, who raised his suspicions when he stated that they had managed to ward off Dalek attacks. Given a DNA tag by Elgin which would allow to pass rely between the hidden library and the outside world, Ace discovered a woman named Bev Tarrant and her massacred team. Attempting to help her, she was captured by a Dalek. Having never left in the first place, the Daleks had used time corridor technology to deploy a hidden Dalek pod on every planet in the sector, hibernating for hundreds of years in wait for a time-sensitive to arrive. The Doctor's arrival having revived them, they set about preparing to penetrate the library's defences and gain access to the wetworks facility, creating a duplicate of Ace, which — replete with the DNA tag given to her by Elgin — would be able to infiltrate the facility.

Once inside, the Daleks successfully downloaded the collective knowledge of the entire universe into a Dalek test subject, but were forced to deem the attempt a failure when, at the conclusion of the download, the subject went out of control. On the planet's surface, the Doctor discovered that the famous Kar-Charrat ziggurat was, in fact, a Dalek pod, prompting him to realise that the Ace who was in the library was in fact a Dalek duplicate. Witnessing a Dalek broadcast threatening to kill Ace if he did not surrender, he was forced to give himself in. Taking him back to the facility, they connected him to the Wetworks and used his mind to process the data for a second test subject, seemingly killing him in the process. In reality, his mind had been absorbed into the Wetworks, where he made contact with the Kar-Charratans, natives who Elgin had enslaved to the facility in order to enable the machine to function, and promised to set them free. Escaping with Ace, Bev, Elgin and the chief cataloguer Prink, the Doctor was aided by the Kar-Charratans, who attempted to enable him to re-enter the surrounded TARDIS by destroying the Daleks guarding it. However, they were intercepted by the duplicate Ace, who, being impervious to the rain, threatened to kill Elgin if they did not return to the facility with her. Prink rushed to Elgin's aid and attacked the duplicate, destroying it at the cost of his own life. The Doctor proceeded to the Wetworks with the intention of destroying it, having Ace pretend to be her own duplicate to get past the Daleks. At the facility they encountered the Dalek test subject and the Dalek Supreme arguing: having obtained something of a conscience, the test subject refused to obey the Supreme's order to destroy the wetworks facility. Deeming their mission a failure, the Supreme retreated to its mothership, leaving the Special Weapons Dalek to kill the test subject, but it was prevented from doing so when the Nitro-9 Ace had set to explode destroyed the facility, freeing the Kar-Charratans. (AUDIO: The Genocide Machine)

After arriving in the midst of the Venddon War and encountering the Voord, the pair tangled with Fleshsmiths and the Master, (PROSE: Prime Time) and re-encountered George Limb. (PROSE: Loving the Alien)

Taking a break from their adventures, the Doctor and Ace visited Chelmsford in 1645 to make repairs to the TARDIS. Saving a young girl called Tilly Brewer from a gang of witch hunters, they learned she had been infected by the Skeeth, a parasite that transformed its victims into fire breathing beasts. As her transformation completed, the Doctor materialised the TARDIS around her, cutting off her Skeeth infection. Knowing that if she left the TARDIS her Skeeth self would return, he built a cottage in the woodlands of the TARDIS, allowing her to spend the rest of her life peacefully inside his spaceship. (PROSE: The Devil Like a Bear)

Tracking a rift in space and time, the Doctor and Ace visited the planet Epajaenda, soon to be turned into a dumping site for toxic waste. They joined the frog-like Travellers, a tribe who lived on the Epajaenda three hundred years ago, in a bid to regain the rights to their home world from a businessman called Abraham-Derris Cuthbertson. The Doctor helped to open a water rift above Epajaenda, making it a habitable planet. However, their plan was opposed by a swarm of deadly rats, led by a Rat King and a Rat Emperor. At the last moment, Cuthbertson rescinded the dumping and honoured the terms of his contract with the Travellers, sacrificing his life to close the rift. (PROSE: Last Rites)

After seemingly freeing the planet Azimuth from Dalek occupation, (AUDIO: Daleks Among Us) the Doctor and Ace were reunited with the Brigadier whilst investigating a mysterious crop circle. Together with a mathematician named Ethan Amberglass, they defeated conceptual beings from another dimension who were attempting to physically manifest themselves on Earth. (PROSE: The Algebra of Ice)

Recalling that Edvard Munch's The Scream was about to disappear under "mysterious circumstances," the Doctor decided to travel to the gallery housing it. He planned to add it to his personal collection, as it was part of established history that it would be stolen. He and Ace arrived on Duchamp 331, a barren, dusty planet, and discovered the painting had been inhabited by the Warp Core, which was animating the planet's dust. Whilst investigating, they encountered the Master, in the form of his previous incarnation: his Trakenite body having been destroyed by the Core, he had reverted to his previous decaying form. He planned to unleash the Warp Core on the universe as an animated planet, but the Doctor, Ace and Bev, who they had re-encountered on Duchamp, managed to stop him. Ace remarked that the Doctor should save them trouble and start collecting stamps. (AUDIO: Dust Breeding)

Attempting to prevent a Dalek invasion on the planet Malite, the Doctor failed and was framed for treason by Premier Mecado, an ally of the Daleks. However, Mecado was killed by the Daleks, and the Doctor's innocence was proven by Ace and Colem Litchen, who had been investigating Dalek Wars. (PROSE: Private Investigations)

Materialising in the grounds of Colditz Castle during the Second World War, the duo became separated when the Doctor was shot in the shoulder and Ace was captured. With the TARDIS confiscated and his friends in confinement, the Doctor was examined by the Nazis and questioned over his strange biology and unusual possessions. Soon after, a woman named Elizabeth Klein arrived and demanded that the Doctor hand over his TARDIS key. Fearing for Ace's safety, he did so, struggling to understand how Klein knew about his TARDIS, and was placed in Klein's custody. He discovered that Klein had forged her identification papers and travelled to this parallel time period in his own TARDIS to capture him and take him back to her alternative future, so he could teach her to fully control it. In her divergent timeline, the Germans had won the war, the Doctor's TARDIS was discovered and he was apparently killed. Klein accessed the TARDIS flight logs to travel to Colditz and planned to learn about the TARDIS before the Doctor died. The Doctor refused, but Klein threatened Ace's life. They discovered that the TARDIS in which Klein had arrived had dematerialised, forcing her to demand use of the TARDIS the Doctor and Ace had arrived in. Back at Colditz Castle, the Doctor manipulated Kurtz, a duty-bound officer, into exposing Klein, and prevented Klein's timeline from ever coming about by locating the CD-player Ace had left behind. Attempting to gain access to the TARDIS whilst it was dematerialising, Kurtz was torn apart on a molecular level before the Doctor and Ace's eyes. Klein escaped, now an anomaly. (AUDIO: Colditz)

After the traumatic events of their visit to Colditz, Ace asked to go somewhere where she could relax. Attempting to find somewhere quiet and peaceful, the Doctor brought her to Ibiza, where a strange DJ called Gabriel who believed that he was an angel was working together with his brother Jude in a rave club. The pair discovered that the brothers were using powers from another dimension to raise an army out of the young people who came to party at their club, recruiting them to fight a war between their people and a militaristic race. The Doctor stopped Gabriel, but was unable to prevent his death, prompting a traumatised Jude to expedite their plans. The Doctor was forced to stop him as well. During this adventure, Ace encountered her previously unknown long-lost brother Liam, and developed a bond. (AUDIO: The Rapture)

Hex joins

After faking his own death, Ace and Hex helped him to expose everything the government had been trying to keep secret, including the deaths of colonists whose bodies were used as fuel. (AUDIO: LIVE 34)

The TARDIS materialised in a wood, where Ace accidentally fell into a lake. Taking her to a nearby cabin, the Doctor discovered a series of murders amongst the group of people staying there, and that the people there were experimenting with time. Ten years earlier, a girl had been killed as a result of a misdiagnosis, and the scientists were attempting to send a message back to warn their past selves. This interference with the timeline caused the girl to become alive again in a state of zombie-like limbo. To correct their mistake, the Doctor travelled back and undid the damage. (AUDIO: Night Thoughts)

The Doctor sent Ace and Hex to Monte Carlo in 1969 to recover the Veiled Leopard diamond.

The Kiseibya had been created to be the natural predator of the Daleks, feeding on metal, but quickly became uncontrollable, decimating the Dalek forces easily. The Doctor planned to blow up the base and slaughter this new species himself, but Beth Stokes, a former prisoner of the Daleks, chose to take his place, staying behind to finish the job. (AUDIO: Enemy of the Daleks)

The TARDIS next landed in the Crimea in 1854, where Hex spent a considerable period recovering from the trauma he had experienced on Bliss by providing assistance to the wounded. There he had an encounter with Florence Nightingale, both his idol and the reason behind his being a nurse. Discovering that he was already caught up in events prior to his arrival, the Doctor, together with Ace, travelled back a short period of time, only to be accused of being spies. Whilst they attempted to convince their captors otherwise, they witnessed the exterior shell of the TARDIS shatter after the HADS was activated by a direct hit from cannon fire, leaving them stranded. Eventually being reunited with it after it had reformed its shell, minus its regular colouration, as it would remain white until it managed to gradually regenerate its shell fully, the Doctor and Ace hurried to pick up Hex. Arriving just too late to prevent Hex from being shot, potentially fatally, the Doctor set a course for St. Gart's. (AUDIO: The Angel of Scutari)

Arriving in 2025, the Doctor managed to successfully perform surgery on Hex, saving his life.

After witnessing Evelyn's death, Hex decided to rejoin the TARDIS crew. (AUDIO: A Death in the Family)

Battling the Elder Gods
Shortly afterwards, the Doctor materialised the TARDIS materialised in Alaska in the 1930s, intending to investigate a strange ice formation. They soon met an expedition team looking for an ancient chamber containing horrors from the dawn of time, and Hex became separated from his friends. Presumed dead, the Doctor and Ace arrived at what appeared to be an island psychiatric facility and met CP Doveday, a poet who claimed to live on the island, who took them to the person in charge. There, the Doctor learned that the entire facility was in fact not a psychiatric complex, but a prison for the most dangerous being on planet Earth – a dormant Karnas'koi. Managing to return the three Karnas'koi within the island to hibernation, Doveday, in reality the fourth "Lurker", sacrificed himself to save the friends. (AUDIO: Lurkers at Sunlight's Edge)

The Doctor left Hex and Ace for a while, growing a TARDIS with a fixed black Police Box outer shell, and began travelling alone in it. After encountering Sandminer robots onboard the cargo ship Lorelei (AUDIO: Robophobia) and meeting a bio-unit based on Nostradamus, (AUDIO: The Doomsday Quatrain) he found a new companion in Private Sally Morgan, a subject of the Bluefire Project, whilst visiting Earth in the year 2020 in an attempt to defeat the Elder God known as the Mi'en Kalarash. (AUDIO: House of Blue Fire) After a while, Lysandra Aristedes joined them in the "Black TARDIS", and the trio continued to seek out and battle Elder Gods. (AUDIO: Black and White, Project Nirvana)

The Black TARDIS arrived in 5th century Denmark, where the Doctor stayed, sending the Black TARDIS, containing Sally and Lysandra, to an alternative 1989. (AUDIO: Black and White)

During his travels in the Black TARDIS, he sent the White TARDIS, containing Hex and Ace, to 1989 in an alternative timeline. He gave them the mission to investigate the Elder Gods, who created this timeline. They managed to defeat the Elders Gods, restoring the original timeline just in time for the Black TARDIS to arrive and retrieve them. (AUDIO: Protect and Survive)

Upon entering the Black TARDIS, they discovered Sally and Lysandra already there, prompting them to realise that the Doctor was travelling in both TARDISes, simultaneously. Hex, Ace, Sally and Lysandra then arrived in 5th century Denmark, where they met Beowulf, and faced an alien called Garundel. They discovered that the Doctor had previously visited this precise location, but had been kidnapped. After following the Doctor's clues and instructions, they retrieved an artefact called Weyland's shield, restored the original TARDIS and destroyed the Black TARDIS, and headed off to locate the Doctor. (AUDIO: Black and White)

The TARDIS crew located the Doctor in a pocket universe which was under the control of Fenric. After releasing the Doctor, it was revealed that Fenric was playing a game against another Elder God called Weyland for control of Weyland's shield, which could grant omnipotence to an Elder God. The TARDIS crew discovered that they had been pawns of Weyland, used to help him win the game against Fenric. Hex was destined to become the quintessential pawn in Weyland's plan, prompting him to prevent his death after he was shot in Scutari. Hex managed to banish Weyland and stop the game, but became possessed by Fenric. He sacrificed himself to prevent Fenric from permanently taking control and gaining power, saving the Doctor, Ace, Sally and Lysandra, surviving only as a being of consciousness in the realm of the Gods. (AUDIO: Gods and Monsters)

The Doctor proceeded to return Lysandra and Sally to their respective times and intended to take Ace somewhere to take her mind off the death of Hex. Ace became furious at him when he showed no remorse or sadness at his passing, prompting him to explain that as a Time Lord he had a different perspective on death as everyone he knew, knows and will know was inherently dead somewhere and somewhen. Unsatisfied, Ace claimed he needed a lesson in humility and forced him to tell Hex's grandmother Hilda what happened to him. Landing in the 21st century, the Doctor proceeded to tell Hilda of Hex's death and organized a funeral for him. Unbeknownst to him, Hex had made a deal with an Elemental named Koloon to have himself removed from the Elder Gods' realm and returned to Liverpool, unwittingly allowing her to remove his memories. Tricked by the being, actually an agent of the Gods, he had become a local crime lord named "Hector Thomas." Discovering this, the Doctor managed to locate the fire elemental, but was too late to save Hex's memories, which were destroyed in front of him and Ace. The Doctor proceeded to send her back to realm of the Elder Gods with a warning: to fear him. Unwilling to accept the death of Hex and the loss of his memories, Ace forced the Doctor to take Hector with them. (AUDIO: Afterlife)

After a rematch with the Nucleus of the Swarm (AUDIO: Revenge of the Swarm) and a visit to Ancient Greece, (AUDIO: Mask of Tragedy) the Doctor and Ace managed to restore Hex's memories and bid him a fond farewell. With a truce called between the Elder Gods and the Doctor, he and Ace set off for new adventures. (AUDIO: Signs and Wonders)

The best of friends
After receiving a warning from his fourth incarnation about a Time Lord demon called the Timewyrm, the Doctor and Ace traced a time anomaly to the kingdom of Uruk in Ancient Mesopotamia, where they joined an expedition, led by Gilgamesh, ruler of Uruk, to a kingdom called Kish. The Doctor was kidnapped by followers of Ishtar, the "goddess of Love and War", but was saved by Ace. Having learnt that Ishtar, in reality a stranded alien named Qataka, planned to influence the whole world using radio transmitters, he sent Ace off to investigate scorpion-like Zuqaqip god Utnapishtim, before entering her inner sanctum. Captured by Ishtar, she attempted to steal his mind in order to gain the knowledge of time travel. After Kish was attacked by a city-like spaceship operated by Ace and her Uruk allies, the Doctor tricked Ishtar into infecting herself with a Zuqaqip virus. She survived, infiltrating his TARDIS and torturing his mind. The Doctor trapped her in the secondary control room and jettisoned it into the time vortex. After uniting Kish and Uruk, the Doctor was horrified to discover that Ishtar had survived and was now a living time machine: he had created the Timewyrm. Realising her powers could destroy time completely, the Doctor set off on a mission to locate and destroy her. (PROSE: Timewyrm: Genesys)

In pursuit of the dangerous creature he had created, the Doctor piloted the TARDIS to an divergent version of 1950s Earth from a timeline where the Nazis had won World War II and were now rulers of the whole planet. They were accused of being resistance fighters and arrested by Anthony Hemmings. Escaping imprisonment, and with the TARDIS once again in the possession of Adolf Hitler and Nazis, he witnessed a Reichsinspektor General being stabbed to death and given an incriminating package before he died. Posing as the General, the Doctor began working with General Otto Strasser in order to gather information on the new timeline. A vengeful Anthony exposed both his and Ace's true identities. Escaping in the TARDIS, the Doctor travelled to 1926 and gained Hitler's trust by giving him the faith to begin World War II. Skipping forward in time, he arrived in 1936, where he was hailed by the Nazis and Hitler as a "hero", becoming his personal advisor. Realising the Timewyrm was controlling Hitler's mind to change history, the Doctor visited him at points when the Nazis invaded various countries across the world. However, he discovered amongst Hitler's closest allies was his old Time Lord enemy, the War Chief. He stopped the War Chief from stealing his remaining regenerations, prevented him from killing Ace as a human sacrifice and foiled his plan to build a Nazi army to conquer the galaxy.

After destroying the War Chief and his new "War Lords," the Doctor visited Hitler in 1940 and drove the Timewyrm out of his body, banishing her into the time vortex. Knowing that he had only weakened her, he resolved to stay wary. (PROSE: Timewyrm: Exodus)

After a final battle within his own mind, the Doctor banished the Timewyrm's power into dormancy and erased its memories. Its "essence," however, was saved, and he implanted it in the mind of a genetically-engineered infant who had previously had no upper brain functions. He gave the baby to Emily and Peter Hutchings, who lived in Cheldon Bonniface, and asked they name her Ishtar. (PROSE: Timewyrm: Revelation)

Returning to the hospitalised Ethan Amberglass, the Doctor entered his dreams and built him a mindscape to explore during his last year of life in a coma. (PROSE: The Algebra of Ice)

Contemplating a solitary retirement, the Doctor travelled to Crook Marsham, where he and Ace were forced to prevent the reawakening of an ancient Sentience trapped within the Earth. (PROSE: Nightshade)

Whilst within the TARDIS, the Doctor decided to set it to undergo some random reconfigurations. Reunited with Ace after she became lost within its vast architecture, he discovered that her bedroom had been deleted, concernedly noting that it was likely due to the TARDIS planning ahead. (COMIC: Cat Litter)

One account claimed that the Seventh Doctor and Ace spent the rest of their respective lives travelling together. After she was kidnapped by the Threshold, the Doctor tracked her down to another plane of existence. Travelling there at the expense of his TARDIS, he witnessed her sacrifice her life in order to destroy one of the Lobri, psychic parasites feeding off the human race's collective fear and hatred. Devastated, the Doctor cradled her dying form in his arms, as she whispered him a final goodbye. Deeply depressed about the affair, the Doctor allowed the TARDIS to reform itself, before becoming involved in the events that would lead to his death. (COMIC: Ground Zero; PROSE: The Threshold)

Time's champion
After taking Ace to the funeral of her friend Julian Milton in Perivale, the pair arrived on the planet Heaven in 2570. Helping Professor Bernice Summerfield open the way to a Heavenite observatory, he deciphered the writing on the telescope and a note stored inside a dead Heavenite's body, discovering a plot by the Hoothi. While entering Puterspace, he was attacked by the Vacuum Church, working in league with the Hoothi, and forced to relive his worst memory: the slow death of his third incarnation. With the help of the psychic Traveller Christopher, the Doctor and Ace were freed.

Realising the danger the falling Hoothi fibres would cause, the Doctor ordered Benny to quickly unearth the observatory, which could detect otherwise invisible Hoothi spheres. Knowing the pyrokinetic, Jan Rydd, whom Ace had fallen in love with, had been affected by the fibres, the Doctor ordered him to leave Ace behind while he went to the sphere himself. Nonetheless, Ace followed him and realised the Doctor's plans. After using Brother Phaedrus of the Vacuum Church to summon the sphere to Puterspace, the Doctor used Christopher to send a message to Jan on board so he could ignite the sphere.

Shocked at the extent of the Doctor's manipulations, Ace finished off the last Hoothi herself, and refused to forgive the Doctor, disgusted that he could sacrificed her lover to save billions. With some reluctance, Benny agreed to travel with the Doctor, under the condition that he didn't treat her the way he did Ace. Having found a new friend, the Doctor took Benny to release the last of Heaven's owls on 20th century Earth. (PROSE: Love and War, AUDIO: Love and War)

Chris and Roz
Still concerned about the dying words of a Hith warrior on Oolis, warning her away from Spaceport Five Overcity on contemporary Earth, Benny discussed the matter with the Doctor, piquing his interest.

Unfinished business
After reconfiguring the console room, the TARDIS brought the Doctor once more to Artaris where he encountered Lord Sutton, the latest incarnation of the Warlord Grayvorn. Grayvorn had been reduced to a spirit after their last encounter and had managed to possess a new host before sculpting Excelis once more into a war-driven dictatorship, using the souls of the rebels of Excelis to power his “meat puppet” army.

Despite their animosity, they worked together to solve a mystery involving an alien virus and prevented a Cheylis plot to use Earth as a testing ground for biological warfare. Knowing Klein would continue to pose a threat to history so long as she remained at large, he insisted she accompany him on his travels so that he could keep an eye on her. (AUDIO: A Thousand Tiny Wings)

Upon entering the TARDIS, the Doctor requested Klein recount precisely what caused her to use the TARDIS that resulted in the destruction of her timeline.

Alone again, the Doctor travelled to the Forge in the hope of shutting it down once and for all. There he found his sixth incarnation assisting Nimrod, and reluctantly helped the organisation fend off a telepathic alien incursion. His predecessor's arm was lost in the battle, confirming the Doctor's belief that this Doctor was a fake. The fake Doctor explained that Nimrod used DNA samples from the real Doctor when they last met to create clones, in an attempt to learn the secrets of regeneration. The clone was rapidly deteriorating, like his two "brothers" had before him. The Doctor revealed to the clone that he had glimpsed suppressed memories during their telepathic contact, prompting him to discover a wing of the base full of decrepit and dying clones. Struggling to cope, the clone initiated the Forge facility's self destruct, allowing the Doctor only five minutes to escape, and killing everyone who remained inside the base. (AUDIO: Project: Lazarus)

Travelling to the planet Pelachan, the Doctor discovered the Hand of All, an artefact that contained a living story. Taking it, the Doctor went to combat a regenerated version of Nobody No-One, trapping him in the Hand inside his mind. He then travelled to the Forge and locked himself inside a Time Lord sarcophagus, waiting until he was found by Ace and his younger self. As he lost control of the Hand, he warned them that Nobody No-One would return before falling comatose. Upon reawakening, he discovered his younger self had died defeating the Word Lord, and took it upon himself to bring Hex to Evelyn on Pelachan and leave Ace with a TG tablet and a lime before he faded out of existence, setting up circumstances to enable his resurrection. (AUDIO: A Death in the Family)

Burning back into existence on the planet Perfugium, the Doctor discovered that his past was catching up on him. Realising that a deal he had made with Death by which she would allow the Master to live a normal life for ten years, was coming to its conclusion, he discovered that it was time for his side of the bargain, to kill him at the end of this time, to be fulfilled. Finding the Master a disfigured amnesiac living in a manor house, he joined him and his friends of ten years Jacqueline and Victor Schaeffer in their evening's entertainment. After being tricked into revealing his mission, the Doctor refused to kill the Master just as he was beginning to enjoy his second chance at life, only for Jade, the Master’s housekeeper, to reveal herself as Death. Unable to fulfil his side of the bargain, the Doctor made another deal with Death after witnessing Victor killing his wife. If the Master could make the right decision, then they’d be free, but the Master struggled when Death presented her choice: his life, as her servant, or the life of Jacqueline, with whom he was in love. In the end, Death took the Master and sent the Doctor away to face punishment for not holding up his end of their bargain, his task to take the place of an assassin and murder an innocent in cold blood. He travelled to the destination and encountered a sniper about to take his shot, interrupted him and recounted his adventure. The Doctor refused to kill his target, but discovered that the sniper was in fact Death, who had known he wouldn't be able to. Before departing, Death proclaimed that they would meet again, and that she knew his inevitable fate. Alone, the Doctor vowed to save his old friend, one day. (AUDIO: Master)

Revisiting the planet Spiridon to oversee events in order to ensure that Kalendorf fulfilled his destiny, the Doctor soon realised that he would have to get involved in order to keep the situation under control. He made a deal with the Daleks to help them achieve their goal of invisibility without suffering from the light wave sickness, in exchange for Kalendorf’s safety. He completed the formula, but betrayed the Daleks at the last moment, exposing them and himself to the sickness. He managed to escape back to his TARDIS, refusing to regenerate, before collapsing. The TARDIS healed him, and he dared the Daleks to catch him if they could. (AUDIO: Return of the Daleks)

The Doctor was reunited with Nimrod, who had been connected to the main Forge computer, Oracle. Realising that he was now the new leader of the Forge, the Doctor left Nimrod a syringe containing the Twilight cure beside him, which would remove his vampirism. However, considering the desiccated state he was in, only the vampire DNA was keeping him alive, and using the cure would cause his death. The Doctor departed, leaving it up to Nimrod as to what he would choose. (PROSE: Twilight's End)

The Doctor delivered a letter from a deceased World War I soldier named Edward Woodbourne, who he had met in his fifth incarnation, to his wife a year after his death, (PROSE: Never Seen Cairo) bought a store in London called "Takahashi's Treasure," encountered a housewife who had died years previously, (PROSE: Running on Empty) and met a young Claire Spencer. (AUDIO: The Word Lord)

Old friends
After hearing of Ace's disappearance from Gallifrey, the Doctor sent Bernice Summerfield to track her down, (AUDIO: The Revolution) and the trio were reunited on Skaro and began to travel together again. (AUDIO: The Lights of Skaro) During these travels, the Doctor tasked Ace with undergoing missions for him solo. One such mission was to prevent time travelling criminal duo Harmonious 14 Zink and his wife 1V Magda from interfering with established history on the planet Erratoon. On this mission she encountered, and believed she had befriended, the living Tracer who went by the name Zara, but was betrayed by her, losing a great deal of her memories in the process. Seeing that she had been successful, the Doctor arrived to pick her up, intending to restore her memories using the TARDIS. (AUDIO: The Prisoner's Dilemma) Later, the three friends found themselves working together again whilst trying to prevent the return of Sutekh. (AUDIO: The Triumph of Sutekh)

After returning Ace to Gallifrey, the Doctor was reunited with Raine Creevy, and the pair began travelling on and off. Whilst the TARDIS was in mid-flight, the Doctor received a distress signal and duo were pulled into another dimension, materialising on a barren planet. Another TARDIS suddenly arrived, carrying an apparent future incarnation of the Doctor, who claimed to be working with UNIT on Earth. He warned the Doctor of a mistake he was about to make, urging him not to help the Tolians, a race of aliens whose life energy was being drained away by a Node Stone, before departing. The current Doctor ignored his warning and conjured up an energy syphon that would draw power from the very dimension, but once the Tolians were restored, they captured Raine and threatened to drop her off a cliff if the Doctor didn't increase the output. Knowing that increasing the output would result in chaos across all dimensions, the Doctor resignedly did as the Tolians demanded and opened up the siphon. He rescued Raine and jumped into the dimensional doorway, explaining that creatures from other dimensions would now be able to freely hop around. He and Raine wandered around the void and were contacted by Ace, who warned them of danger on behalf of the Time Lords. Losing her signal, the Doctor instructed Raine to pick the dimensional lock with her mind, opening a door to another dimension.

Entering into another dimension, Raine and the Doctor found themselves on a volcanic world inhabited by lava-spewing spiders. Seeking refuge in a dormant volcano, the pair discovered that it was a hatchery and were chased out by more spiders. Noticing another dimensional door which the arachnids were using to cross over to Earth, the pair followed, unaware that the future Doctor, being assisted by the Doctor's old acquaintance Elizabeth Klein, was preparing to banish the spiders that had already escaped to Earth back into their dimension of origin. Fortunately, the future Doctor noticed the travellers and rescued them using a Skyhead.

The current Doctor learned that UNIT had confiscated his future self’s TARDIS to force him to help them fend off a variety of dimensional escapees. Detained by a suspicious UNIT, the Doctors pleaded to have the second Node Stone, currently in Klein’s possession, to close up the breach, but she refused. Before long, two more sets of creatures, the Nexus, a gestalt cephalopodic species with faces on each tentacle, and flying metallic cubes which could fire energy pulses and explosively self-destruct, appeared in Las Vegas and Tokyo. Whilst the future Doctor and Raine travelled to Japan to sort out the Nexus, the current Doctor and Klein dealt with the cubes, discovering their greatest weakness – fire. After the situation was resolved, the cubes joined together in a final, desperate attempt to blow the dimensional doorway to their dimension bigger. Seeing no other way, the future Doctor was called in to help, but demanded the release of his TARDIS and the Node Stone before he helped them. Reluctantly, Klein did as he ordered, only for him to promptly fly off, before suddenly returning to fix the situation. It turned out that he’d time travelled back to the second after he arrived in England. UNIT started shooting at the future Doctor until he doubled back into his TARDIS, followed by his younger self. Inside, the Doctor realised that the future Doctor was really. The Master had pretended to be the Doctor and planted the first Node Stone on Earth, conning the Doctor into opening the dimensional doorway so that he could power up the Tolians and assume mastery over every dimension. The Master captured the Doctor and hooked him up to the Node Stone, but the Doctor, with the help of footage his companions had showing the Master planting the first Node Stone, managed to convince the Tolians to betray him and restore the dimensions. Saving the Earth, the Doctor was unable to prevent the Master from escaping in the confusion. Afterwards, the Doctor left Klein a space-time telegraph to contact him should she need his help again, before leaving with Raine. (AUDIO: UNIT: Dominion)

Nearing the end
Sensing his end approaching, the Doctor became afraid that whatever man came after him wouldn't be strong enough to do what he did, or that he wouldn't be willing to go as far as he had gone. He started to do whatever he could to seek out evil in the universe wherever he could find it and shut it down while he still could. To this end, he began to monitor interstellar communications across thousands of worlds, the wireless communications of a multitude of law enforcement organisations, private correspondence of governments and the criminal underworlds by persuading the TARDIS to detect their transmissions. The Doctor detected that Kurt Schalk in 1945 had become the most wanted man in the universe, and set out to discover why. Discovering that Elizabeth Klein's current self was somehow connected to Schalk, he travelled to the 1990s to take her with him on this trip. He managed to make Klein follow him from a pub into his TARDIS and take her along without her consent, while also, unbeknownst to him, taking along junior science officer Will Arrowsmith with them.

Travelling to Düsseldorf in 1945, they met a Nazi named Lucas Hinterberger, a colleague of Schalk's. Opening up immediately to Klein, raising suspicion in her and curiosity in the Doctor, he told them about beings they called the Struwwelpeter, due to their appearance being similar to that of creatures in a German children story, and offered to take them to Schalk. While searching the Doctor explained his reasons to Klein who understood his reasoning. Finding Schalk, they also came face to face with the Struwwelpeter, godlike beings from another universe whose true names were the Shepherd and Shepherdess. Considering this universe to be evil and decadent, they gave Schalk the knowledge to built a device known as the persuasion machine so that they could manipulate all beings in the universe to submit to their will. The Doctor trapped them on New Peerlessness, a prison planet near Kasterborous. While the Doctor dealt with them, the Klecht entity took Schalk, forcing the TARDIS crew to search for him. (AUDIO: Persuasion)

After discovering an intergalactic commercial voiced by old acquaintance Garundel regarding a weapons auction, the Doctor realised it was auctioning Schalk alongside a prototype of the persuasion machine. Fearing his presence would raise Garundel's suspicions, the Doctor sent Klein and Will undercover in order to locate Schalk and steal him before he and the device were sold. While they investigated the auction, the Doctor waited inside the TARDIS for them to enable him to land inside the compound. Will gave the signal and he landed, but was intercepted by Garundel's assistant Ziv, who captured Will and locked him out of the store room, in actuality a space ship. At that moment the auction was invaded by the Sontarans. He encountered Garundel, who forced him to go in pursuit of his assistant and Will. He learned from Garundel that Schalk didn't have enough knowledge of the machine. When they arrived, the Sontaran invading fleet caught up with them, with Klein as their hostage. They fired at them, but they escaped to the ship, reuniting with Will. Will negotiated Klein's exchange and the Doctor discovered that the man they were selling was not actually Schalk but was instead the man they met on Minos, and that he was dead. The Doctor used the prototype of the machine to persuade Garundel to go with Ziv and rescue Klein. The Doctor explained to Will that the body they found was actually Hinterberger: Schalk had used the machine to persuade Hinterberger he was Schalk and then used it on himself to convince himself that he was Hinterberger. The Doctor boarded the Sontaran ship and discovered that a third party was involved. Reuniting with Klein and Will, they left, with the prototype revealing to Klein her biological connection to Schalk. (AUDIO: Starlight Robbery)

The Doctor and crew returned to Minos in 1945 where he discovered that the third party were the Daleks. Travelling to Lemuria, he was given the location of Schalk: the planet Azimuth, years after he had previously visited it.

On Azimuth, they discovered it had become illegal to mention the Daleks or remember the occupation. Will was captured by the police when the Doctor mentioned them by name out loud. The Doctor and Klein got an audience with a prisoner whom the Doctor identified as a clone of Schalk, specifically a Dalek clone. They concluded that the Daleks were still in Azimuth, only hidden. The Doctor revealed to Klein that there was a blood connection between her and Schalk, prompting her to ask to travel to 1945 to discover the truth. Will returned to them and told them about a man called "Father" that wanted a meeting with the Doctor. Going to the meeting alone, he discovered that Father was actually Davros, who asked him about the location of the Daleks, something neither of them knew. Both Davros and the Doctor were taken to the Daleks and Schalk, enabling the Doctor to discover that Klein travelled in the TARDIS to three weeks before they first arrived in Düsseldorf. She had discovered that Schalk was her biological father and a woman named Elizabeth Volkenrath was her biological mother, and that she was engineered to operate the persuasion machine. At that moment, Elizabeth returned in the TARDIS and, having seemingly reverted to her Nazi self, claimed to be willing to become the tool for the persuasion machine. A man called Falkus entered the room and revealed himself as a genetic successor of Davros, ordering the Daleks to exterminate Schalk. Falkus wanted to undo the actions the Doctor had done through time and space. Despite Davros' interruptions, Elizabeth forced the Daleks and Falkus to die with the power of the machine. Will returned with the Shepherd, who threatened to kill them, but Elizabeth used the power of the machine to kill it, dying in the process. The Doctor and Will realised that the Elizabeth who had died wasn't Klein, but her mother, prompting them to search for her on Earth, 1945. Tracking her to Russia where she had been trapped, he apologised to Klein for judging her by her alternative self. Will alerted them to the fact that they were surrounded by the Red Army, and an excited Doctor prepared for their next "adventure". (AUDIO: Daleks Among Us)

Following an encounter with Mozart and the Monk, the Doctor travelled for a short period of time with a tramp. (PROSE: The Tramp's Story)

Alone again, the Doctor visited Valhalla, the Capital City of Callisto, and became embroiled in a plot by a swarm of evolved termites to take over the city and sell its population as slaves. After thwarting their plan, he offered a maintenance worker named Jevvan the chance to travel with him, but was turned down. (AUDIO: Valhalla)

Visiting Mars millions of years BC, the Doctor managed to stop an attempt to take over the Martian government made by Arakssor with the support of a band of warmongering Ice Warriors. With the help of Geldar, the Doctor ensured that Arakssor and his band of war criminals were sentenced to life imprisonment in Antarctica. However, the war criminals staged an escape, resulting in everyone within the facility becoming trapped in suspended animation beneath the ice. In 2012, an amnesiac Doctor and the Ice Warriors were unearthed by a human expedition led by Lord Barset. Arakssor quickly resumed his gambit, planning to power the prison's sonic cannon to eradicate the Earth's greenhouse gases, thus making the planet into a fortress that Martian life could thrive in, wiping out the human race in the process. As his memories began to return, the Doctor commandeered a helicopter, Blade One, with the crew's physicist, Genevieve Marceau, and crash-landed near the dig site after the helicopter was hit by Ssrongar's sonic cannon. The Doctor reactivated Geldar's distress signal and boosted it to contact a Martian warship from the other side of the galaxy. The Martian commander, Red 0089, discovered the message, and, upon recognising Arakssor, bombarded the prison from orbit, destroying Arakssor and the rest of the Warriors. The Doctor and Geni fled to the safety of the TARDIS, before returning to the Fortitude to drop Geni off. (AUDIO: Frozen Time)

Still alone, the Doctor arrived on a space station that was orbiting the quarantined planet Antikon. It had fallen victim a virulent disease that had killed millions of people. Encountering the Dar Traders for a second time, he discovered that the disease was a sentient virus which preyed upon all matter, called Decay. Attracted to death, Decay boarded the space station. The Doctor managed to contain Decay within the TARDIS, but it refused his offers and claimed a final life, ending its own life in the process. (AUDIO: The Death Collectors)

Tracking a strange signal, the Doctor arrived on the planet Tasak and encountered an android named Temeter. Discovering that they were both tracking the same signal, the pair formed an alliance. Together they travelled across Argent City via the monorail transport system to the Grand Citadel of the House of Argentia where they discovered a plot by the members of the House of Sarkota and encountered Sara, the android Temeter had been trying to rescue. Before they could leave, they were arrested as spies and brought to the banquet hall, where a Cyberman statue was unveiled. The Doctor tried to warn the people of the dangers, but they ignored him. As Argentia was taken over by the leaders of Sarkota in a coup, the Doctor and his allies discovered that the Silver, the core of the planet’s technology repository, was in fact a Cyberman device, and that still present on the planet was a hibernating squadron of Cybermen. Upon awakening, the began to convert the planet’s inhabitants. The Doctor managed to lead them into a trap before destroying the entire repository. (AUDIO: Kingdom of Silver)

Arriving in the remains of the Drashani Empire, the Doctor met a mercenary called Vienna Salvatori who had been hired to capture him for a bounty payment. He soon encountered an old enemy, Tenebris, who he had met previously in his sixth incarnation on his second visit to the Empire on Cawdor. However, he discovered that Tenebris was, in fact, Kylo Sorsha, a prince he had left stranded on the planet Sharnax when he first encountered the Drashani Empire whilst in his fifth incarnation. Sorsha plotted to take revenge against the Doctor for leaving him stranded on Sharnax, but the Doctor defeated him, and departed from the empire for the final time. (AUDIO: The Shadow Heart)

Becoming weary of his solidarity and his invitations being declined, the Doctor decided to create a robotic companion, which he named Catherine Broome. The duo travelled together for a while, facing the Cybermen and Gelsat creatures whilst the Doctor allowed Cat to believe that she was from the 20th century. Arriving on Haven in the 28th century, the Doctor revealed Cat's true nature to her in time to avert a catastrophe on a spaceship. In order to prevent the destruction of the ship, and the deaths of many colonists, Cat travelled through hazardous corridors to the control to save the lives of hundreds. (PROSE: Companion Piece)

Once again alone, the Doctor arrived at a Reclaim Station in the Easto Cluster in search of fluid links for his TARDIS. He and Two'Mark, the mechanic, were approached by a small robot who recognised the Doctor. The two of them then headed back to his TARDIS, where the Doctor activated a holo-glyph control and started to play back a recording, made by old android acquaintance Sara many years ago. The recording detailed her prosecution following a failed mission and her condemnation: to have her consciousness transferred to a worker robot with her emotional capabilities stripped away as punishment. Feeling melancholy, the Doctor offered to pay Two'Mark for the fluid link, but the engineer stated that their discovery had gotten him in the mood to be generous, and allowed him to have it on the house. (AUDIO: Keepsake)

Feeling nostalgic, the Doctor travelled to 1979 Paris, where he watched his fourth incarnation and Romana do battle with Scaroth. Whilst there, he rescued a sketch of Romana that his younger self threw away. (PROSE: Notre Dame du Temps)

Death
Recalling his duty involving the transportation of 's remains, (PROSE: Lungbarrow) the Doctor finally went to collect his ashes, (TV: Doctor Who) using a faulty Chameleon Arch to turn himself half-human in order to trick him in the likely event of his escape. (COMIC: The Forgotten)

En route to Gallifrey, the Master escaped from his casket in the form of a Deathworm Morphant and damaged the inner workings of the TARDIS console. The Doctor was forced to make an emergency landing in San Francisco on 30 December 1999. No sooner had he left the TARDIS to find his bearings, the Doctor was caught in the middle of a San Francisco gang war and shot, once straight through the shoulder and twice in the leg. The Doctor tried in vain to get Chang Lee to stop the Master from leaving the TARDIS, before falling unconscious.

Taken to Walker General Hospital, the bullets were found to have caused only minor injuries. However, the medical team assumed that he was fibrillating and that the X-rays showing his two hearts was a double exposure. Cardiologist Dr. Grace Holloway undertook exploratory surgery to "fix" his abnormal heartbeat. Waking up just as Holloway began the surgery, the Doctor tried to stop the surgery by explaining his non-terrestrial origins, but the surgeons quickly began to put him under anaesthetic. He attempted to warn them about the Master, but soon returned to unconsciousness.

Holloway rapidly became lost in the Doctor's strange cardiovascular system, and he began to flatline when she damaged his circulatory system with her probe. Though the team attempted to revive him, their attempts failed, and they pronounced him dead. Unlike his previous deaths, his regeneration did not begin promptly; his successor attributed his delayed regeneration to having been under anaesthesia at the time. The hospital staff locked the Doctor's deceased body inside a cold chamber, with a "John Doe" toe tag attached and a sheet placed over his body.

Several hours later, within the hospital morgue, the Doctor's corpse contorted and crackled with electrical energies as the regeneration process began, giving him new life in the form of his eighth incarnation. (TV: Doctor Who)

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

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Seventh Doctor, appeared inside it to defend themselves as well. (COMIC: Dead Man's Hand)

Undated adventures

 * The Seventh Doctor attended the funeral of Alistair Gordon Lethbridge-Stewart, as did all of his other incarnations. (PROSE: The Gift, Shroud of Sorrow)
 * River Song met the Seventh Doctor, calling him "surprisingly Scottish." She had his memory wiped with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)
 * Sporting a beard, the Seventh Doctor met Honoré Lechasseur, who described him as a "small Scottish doctor". (PROSE: The Cabinet of Light)

Alternative timelines
In an alternative timeline, the Doctor and Ace were captured in Colditz Castle in October 1944. When they tried to escape, Ace was killed, and left behind her walkman. This provided the Nazis with laser technology, which they exploited to win the Second World War. Immediately afterwards, the Doctor returned to Germany in 1955, where he was shot by Nazi soldiers. He later regenerated into an alternative version of his eighth incarnation. (AUDIO: Colditz, Klein's Story)

In another alternative timeline, the Doctor was able to save Jan Rydd and his fellow Travellers on Heaven in 2570. In a third alternative timeline, the Doctor was beheaded by an Ice Warrior on Peladon in 3985. (PROSE: So Vile a Sin)

Personality
The Seventh Doctor was originally light-hearted and prone to clownish behaviour, which masked his intellect and courage. (TV: Time and the Rani, Paradise Towers, The Greatest Show in the Galaxy) However, as he matured, he became a grumpy and melancholy manipulator who saw the battle between good and evil as a game of chess, and everyone around him as pawns in the game of fighting evil. (TV: Remembrance of the Daleks, Silver Nemesis, The Curse of Fenric; PROSE: Head Games)

Influenced by his predecessor's decision to let his morality and scruples die with him in his final moments, (AUDIO: The Brink of Death) the Seventh Doctor actively sought out villains to vanquish and dictatorships to dethrone, as opposed to his previous incarnations, who would stumble upon trouble by happenstance. (TV: Remembrance of the Daleks, The Happiness Patrol)

Being the most dangerous of the Doctors, (AUDIO: Persuasion) he would often see only the "bigger picture" rather than the world before him, (PROSE: Head Games) which resulted in him causing much grief, such as devastating Ace by labelling her an "emotional cripple" to weaken Fenric's power by making her abandon her belief in him. (TV: The Curse of Fenric) However, he was not totally unfeeling, as he appeared apprehensive about his decision to destroy Skaro, (TV: Remembrance of the Daleks) and was genuinely agonised that he had to convince Ace that he did not care about her. (TV: The Curse of Fenric)

Despite his manipulative actions, such as using psychic powers to make Mel leave with Sabalom Glitz, (PROSE: Head Games) the Seventh Doctor did care for his companions, (TV: Battlefield; AUDIO: The Fearmonger) and even sought their approval on occasion. (PROSE: Head Games)

Although he originally invited her to travel with him due to Fenric, (PROSE: Head Games) the Doctor developed a paternal relationship with Ace. (TV: Remembrance of the Daleks, Silver Nemesis, The Greatest Show in the Galaxy, Ghost Light, The Curse of Fenric, Survival) Though their relationship soured when she found herself unable to deal with his growing emotional coldness, (PROSE: Nightshade) she eventually decided that, whilst he "may be a bastard," he was "still [her] bastard." (PROSE: Head Games) She believed that he had the "deepest, saddest eyes," (AUDIO: The Prisoner's Dilemma) and even told him that she loved him. (AUDIO: Signs and Wonders)

Although his more whimsical tendencies disappeared over time, the Doctor maintained a fondness for idiosyncratic speeches that occasionally referred to literature, ordinary places and even food and drink amidst the weightier concerns on his mind. (TV: Survival) Other times, he would sombrely reflect the ramifications of time, and the consequences of interfering in history. (TV: Dragonfire, Remembrance of the Daleks)

He "couldn't stand" burned toast, loathed bus stations, calling them "terrible places full of lost luggage and lost souls," and hated unrequited love, tyranny and cruelty. (TV: Ghost Light)

In direct contrast to his previous incarnation, the Seventh Doctor was opposed to violence of any sort, although he proved capable of rendering an opponent unconscious with a touch. (TV: Battlefield, Survival) While he was completely against the use of firearms, (TV: The Happiness Patrol) the Doctor was willing to use a Tissue Compression Eliminator to defend himself against Death's Head. (COMIC: The Crossroads of Time)

While his human counterpart fell in love with Joan Redfern, (PROSE: Human Nature) the Doctor himself was decidedly celibate. (AUDIO: Bang-Bang-a-Boom!) He could also be critical of human nature, stating that humans had "the most amazing capacity for self-deception, matched only by [their] ingenuity when trying to destroy [themselves]," (TV: Remembrance of the Daleks) and that "among all the varied wonders of the universe, [there was] nothing so firmly clamped shut as the military mind." (TV: Battlefield)

Nearing the end of his life, the Doctor decided to retire from his niche of manipulation. Feeling guilty and tired from his plotting, he acknowledged he had lived past his prime and would soon regenerate. Fearing that his next incarnation would not want to continue plans that he had set in motion, the Doctor put all his affairs in order to leave nothing unsung when his time drew to a close. (AUDIO: Persuasion) However, after being saved from one of the Eight Legs by the Eighth Doctor, he became determined to enjoy every minute of his current incarnation. After the Eighth Doctor warned him of a trap by, the Seventh Doctor decided not to think about it, and let fate decide when and how his life would end, instead of despairing over being alone. (PROSE: The Eight Doctors)

The Seventh Doctor was generally disliked by his other incarnations. (AUDIO: The Shadow of the Scourge) The Fifth Doctor was repulsed by his manipulative nature, (PROSE: Cold Fusion) and the Sixth Doctor told Evelyn Smythe that his successor was "always blowing up planets," (AUDIO: A Death in the Family) something he was "not looking forward to." (AUDIO: Arrangements for War) The Eleventh Doctor described his seventh incarnation as "probably one of [his] more circumspect periods." (AUDIO: Shockwave)

The Eighth Doctor came to view his immediate predecessor's manipulative nature with disdain, telling Lucie Miller that he was always "the man with the master plan," arranging the destruction of his enemies and the toppling of dictatorships in order to serve the greater good, to the point where he began to countenance sacrificing the lives of the few to save the many. (AUDIO: The Resurrection of Mars)

Iris Wildthyme described the Doctor as "a portentous little feller, swaggering around, thinking he's got all the world's darkest secrets under his hat." (PROSE: The Scarlet Empress) Brigadier General Adrienne Kramer described him as "a manipulative little weirdo who was always up to something behind [her] back." (PROSE: Vampire Science) When she encountered the Seventh Doctor shortly before her death, Evelyn Smythe criticised him for his scheming, manipulative nature, (AUDIO: A Death in the Family) while Melanie Bush described the man he became as "a liar and a user and quite possibly a murderer," and proclaimed that she wanted nothing more to do with him. (PROSE: Head Games)

described the Seventh Doctor on one occasion as a "tiresome little man with [an] umbrella," (AUDIO: Eyes of the Master) while Alan Fitzgerald, a summer intern at the Gogglebox, believed that the Seventh Doctor knew everything. (AUDIO: The Gathering)

The Doctor told Chris Cwej that he viewed regenerating as both a good and bad feeling in the same way that driving a car very fast was a good and bad feeling; enjoying the exhilaration of the process but knowing that you were going to "die" at the end. (PROSE: The Room With No Doors)

After getting shot in a gang shootout in San Francisco, the Doctor spent his last lucid moments desperately trying to warn Dr. Grace Holloway not to operate on him, proclaiming his need to stop and, after succumbing to sedation, screaming in agony when the operation dealt fatal damage to him. (TV: Doctor Who) Holloway noted that the Doctor seemed "very clear, very determined and very powerful" while also looking "very serious but also very frightened of something", and felt that he was "rarely afraid of anything". (PROSE: Doctor Who) The Doctor later recalled his demise as being "undignified," and expressed annoyance that he "[hadn't seen] that one coming." (AUDIO: Zagreus)

Habits and quirks
Speaking with a Scottish accent, the Seventh Doctor occasionally rolled his 'R's and emphasised his 'P's and 'L's. (TV: Paradise Towers, Delta and the Bannermen, The Greatest Show in the Galaxy)

The Doctor was a consummate fan of chess, to the point of treating his companions and enemies as pieces on a chess board. (TV: The Curse of Fenric) Despite his tendency toward a dark personality, his seventh incarnation was known for his use of words to resolve problems instead of violence. (TV: Dragonfire, Remembrance of the Daleks, Silver Nemesis, Battlefield, Ghost Light, Survival)

The Doctor occasionally displayed a tendency to mangle and combine Earth idioms, creating Dundrearyisms. (TV: Time and the Rani, Delta and the Bannermen) After Mel described the habit as "really annoying," the Doctor promised that he would try to stop doing it. (AUDIO: Bang-Bang-a-Boom!)

As he met new people, the Doctor often raised his hat to greet them, smiling as he did so. (PROSE: Lungbarrow) He also collected pins, simply out of the enjoyment of doing so. (PROSE: Lucifer Rising)

Skills
The Seventh Doctor was a grand manipulator, often utilising his choice of words to persuade others into a decision of his choosing, (TV: Paradise Towers, The Happiness Patrol) or devising an unscrupulous scheme to defeat his adversaries. (TV: Remembrance of the Daleks, The Curse of Fenric) Something of a showman, the Doctor was an adept physical performer, and deployed a repertoire of magic tricks, illusions and escape artistry as part of his plans. (TV: The Greatest Show in the Galaxy) When his plans went awry, or an unexpected element developed, the Doctor was efficient at improvising around it. (TV: Remembrance of the Daleks)

Despite his stature, the Doctor was capable of both directly and indirectly taking control of situations involving strangers, using his greater intelligence to assess and direct events. (TV: Remembrance of the Daleks, The Happiness Patrol) While he loathed violence, the Doctor also showed a skill at unarmed combat, being able to briefly overpower a judo trained Mel and a Cheetah virus infected Master. (TV: Time and the Rani, Survival)

The Doctor also showed a knack for playing the spoons as a musical instrument, (TV: Time and the Rani, The Greatest Show in the Galaxy; AUDIO: Colditz, Afterlife) though this was seen less as he matured. (AUDIO: Master) Representing Earth in lieu of Nicky Newman, he won the 309th Intergalactic Song Contest by playing the spoons. (AUDIO: Bang-Bang-a-Boom!)

The Doctor used eye-fixation hypnotism to influence the minds of Peter Warmsly and Pat Rowlinson, convincing them to evacuate Gore Crow Hotel. (TV: Battlefield)

To fool the genetic scanner used by the Imperial Landsknechte on Purgatory, the Doctor underwent a partial regeneration, a process that gave Time Lords a new set of gene but used up a lot of regenerative energy. (PROSE: Original Sin)

Appearance
The seventh incarnation originally appeared to be a short man in his mid-forties with bright blue eyes. (TV: Time and the Rani)

Peri Brown described him as a "kooky little guy in a weird pullover." (AUDIO: The Veiled Leopard)

Hair and grooming
While he had a full set of hair after his regeneration, (TV: Time and the Rani) the Doctor allowed his greying hair to grow out into tufts on the sides of his head, while it thinned a bit at the top of his scalp, by the end of his life. (TV: Doctor Who)

Clothing
To begin with, the Doctor wore an off-white safari-styled jacket with a red paisley handkerchief in his left pocket, a tartan scarf under his lapels and a battered white colonial-styled Panama hat with a red paisley hatband and an upturned brim. Underneath his jacket he wore a yellow pullover with turquoise zigzag lines and red question marks, tucked into his sand-coloured tweed plaid trousers and with pair of red braces over it. Under the pullover, he wore a white shirt with a red paisley tie, and completed his outfit with a pair of two-tone white and brown brogued spectator shoes. (TV: Time and the Rani) After he lost his scarf during his clash with the Rani, he was forced to replace it with a red paisley one, (TV: Paradise Towers) and later replaced his battered hat with a new one. (TV: Remembrance of the Daleks)

After giving his white coat to Rebeekan on the planet Rebeeka VI, (PROSE: It's Only a Game) the Doctor replaced his jacket with one that was chocolate brown in colour, and changed his hatband, handkerchief and scarf and tie to ones of more subdued shades of burgundy and brown. (TV: Battlefield)

During his travels with Ace and Benny as Time's Champion, he removed his pullover and replaced his jacket and trousers with a cream linen suit. (PROSE: White Darkness)

By the end of his life, the Doctor wore a light brown tweed jacket, with a red paisley waistcoat, plaid trousers and a black and brown, zigzag patterned tie. (TV: Doctor Who)

Umbrellas
After his regeneration stabilised, the Doctor took to carrying around an umbrella as part of his day-to-day outfit, whether the occasion called for it or not. (TV: Time and the Rani, Paradise Towers, Delta and the Bannermen, Dragonfire)

He initially carried his previous incarnation's multi-coloured umbrella, but was forced to leave it in the Rani's base on Lakertya where it was destroyed. (TV: Time and the Rani) Saddened, he managed to find a suitable replacement within TARDIS wardrobe: (PROSE: The Useful Pile) a black umbrella with a handle. (TV: Paradise Towers)

After his black umbrella was damaged, (AUDIO: The Warehouse) the Doctor acquired a new umbrella, with an elaborate handle in the shape of a large red question mark. (TV: Delta and the Bannermen) The handle could split in half (COMIC: Planet of the Dead) and was also detachable, hiding a secret compartment containing a vial of Time Lord restorative. (COMIC: The Forgotten)

Casting
Actors considered for the role of the seventh incarnation before McCoy was cast included Rowan Atkinson, who later played the ninth incarnation in the satirical The Curse of Fatal Death; McCoy's mentor Ken Campbell; Chris Jury; Tony Robinson; and Alexei Sayle. Sayle had previously played the DJ in TV: Revelation of the Daleks. Furthermore, Andrew Sachs and Dermot Crowley auditioned for the role.

Cartmel Masterplan
Season 25 and 26 had broad hints that the Doctor was not simply a Time Lord, as previously shown and stated. This overarching plot, conceived by Script Editor Andrew Cartmel and referred to by fans as the Cartmel Masterplan, was designed to restore an element of mystery in the Doctor and his true nature as in the stories of the first and second incarnations. Although the cancellation of the series at the end of Season 26 prevented further on-screen exploration of this arc, it was later given full rein in the Virgin New Adventures novel series.

Parodies and pastiches

 * After the original series ended, Sylvester McCoy and Sophie Aldred played characters called the Professor and Ace, respectively, in a series of audio adventures produced by BBV Productions. Initially the stories were clearly based upon Doctor Who, but these connections decreased when the character was renamed the Dominie and Aldred's character Alice.
 * McCoy also parodied his version of the Doctor in the BBV production, Do You Have a Licence to Save This Planet?.
 * In the BBC series,, Sylvester guest-starred as Graham Capelli, an actor who had played the titular role in The Amazing Lollipop Man, a cult 1980s children's television series. The Lollipop Man had many similarities to the Doctor.
 * An Easter Egg referencing the Seventh Doctor appears in the seventh episode of the first season (The Tale of the Captured Souls) of the Nickelodean children's horror series, Are You Afraid of the Dark?. The Seventh Doctor's hat and coat can be seen hanging from a hatstand at two points in the episode.
