## Behind the Scenes

### Latest Appearance

Destiny

Filled with wanderlust and a renewed curiosity towards exploring time and space, the **Fourth Doctor** left all ties of his previous incarnation's exile behind on Earth, setting off to travel the universe, taking advantage of his freedom once more.

This incarnation of the Doctor initially travelled with Sarah Jane Smith and Harry Sullivan, but Harry chose to remain on Earth when the opportunity arose. The Doctor and Sarah continued on their adventures until the Doctor was summoned to Gallifrey, necessitating that he leave her behind as humans were not allowed on Gallifrey at the time.

After tangling with the Decayed Master on Gallifrey when he tried to heal himself and renew his regeneration cycle, he met and travelled with Leela of the Sevateem. During his travels with Leela, the Doctor gained a new companion in the robot dog, K9. Returning once more to Gallifrey to stop an invasion of Vardans, Leela and the original K9 stayed behind there.

On the White Guardian's orders, the Doctor began looking for the Key to Time with fellow Time Lady Romana and K9 Mark II. Once that search was concluded, the Doctor and Romana went on the run from the Black Guardian. Not long after, Romana regenerated into a new body and continued to travel with the Doctor and K9. When they attempted to answer a Gallifreyan summons, the trio accidentally passed into the smaller universe of E-Space.

During his travels in E-Space, the Doctor gained a new companion in the teenaged mathematical genius Adric. Romana and K9 stayed behind in E-Space as the Doctor and Adric departed for N-Space. There, they encountered a Trakenite named Nyssa and a human named Tegan. The foursome successfully prevented the destruction of the universe by the Master, but only at the cost of this incarnation's life.

The Doctor prepared for the worst when the Watcher, an entity born of his own immediate future, appeared to warn him of his demise. Due to the Master messing with the rotation controls for the Pharos radio telescope, the Doctor fell a great height. Suffering terrible injuries, he was assisted by the Watcher in his last moment, who joined with him and helped him regenerate into his next incarnation.

## Biography

### Post-Regeneration

The Third Doctor's death took place ten years after the radiation from the Great One's lair caused severe damage to his body. (TV: *Love and War*) He returned to Earth to end his time in the company of Sarah Jane and the Brigadier. Cho-Je soon arrived and kick started the regeneration. (TV: *Planet of the Spiders*)

Once he had regenerated, the Doctor suffered delirium, mumbling random things from his past adventures, and was physically exhausted. He was put in sickbay, where medical officer Harry Sullivan kept watch on him. However, the Doctor managed to outwit him and get to his TARDIS to leave. (TV: *Robot*)

Slipping away from UNIT HQ, (PROSE: *Doctor Who and the Face of Evil*) the Doctor visited a planet colonised by the Mordee expedition, and encountered the colony ship's powerful computer, Xoanon, which he repaired from damage Xoanon sustained, accidentally imprinted his own mind on the computer, leaving him with multiple personalities. (TV: *The Face of Evil*) He also visited Pesca, and encountered the Pescaton leader, Zor. (AUDIO: *Doctor Who and the Pescatons*)

Returning to UNIT HQ, though still with situational awareness issues, the Doctor was asked by the Brigadier to help deal with the Think Tank and their K1 robot, which had gone insane from so many contradictory orders its programming should have prevented it from doing. Afterwards, he returned to travelling in his TARDIS, taking Sarah Jane and Harry with him, abandoning a UNIT dinner party at Buckingham Palace and leaving without telling the Brigadier. (TV: *Robot*)

### The *Nerva Beacon*

Due to Harry's inadvertent interference with the helmic regulator, the TARDIS landed on *Space Station Nerva*, where humanity had been cryogenically suspended to await Earth's recovery from solar flares. There, the Wirrn wished to use the humans as food and incubators for their kind after the human race had destroyed their breeding colonies throughout the Andromeda galaxy in a thousand-year battle with them, sending them into space. Unable to reproduce without terrestrial colonies, they sent their queen to the *Nerva Beacon*, who birthed several larvae before she died from the *Nerva Beacon* auto-guard. The larvae began to feast on humans, absorbing their knowledge and their bodies. Luckily, Noah, a human was converted into a Wirrn, retained his strong will and tricked the Wirrn into a suicide. Afterwards, on behalf of the space station, the Doctor went down to Earth with Harry and Sarah Jane to fix the transmat relay, leaving the TARDIS on the station, while Vira, the station's first medtech, tended to waking the rest of her crew from their long sleep. (TV: *The Ark in Space*)

Once on Earth, they found the Sontaran Styre conducting experiments on humans as a prelude to an invasion. Caught in the wrong place at the wrong time, the Doctor was accused of murdering a GalSec officer among a crew who had been lured to the Earth and slowly picked off by Styre. After escaping them, he rescued Sarah from an experiment where her inner fears were used against her. Styre appeared to fatally shoot the Doctor as he fled, but the Doctor had nicked a piece of the Nerva's synestic locking system, which guarded him from injury.

Knowing a Sontaran would not refuse an opportunity to engage in mortal combat, the Doctor returned and challenged Styre to a duel. This wore him out and bought Harry enough time to remove a terullian diode bypass transformer from the ship that nurtured Styre with energy, making the energy feed on Styre instead. The Doctor went on to address the Marshal who had sent Styre to Earth. The Doctor defeated his plans by bluffing the Marshal to call off his attack, allowing the resettlement of Earth to proceed, and transmatted with his companions back to the space station to retrieve the TARDIS. (TV: *The Sontaran Experiment*)

Intercepting their transmat beam, a Time Lord messenger appeared to the Doctor and forced him to undertake a mission on the Time Lords' behalf: prevent the creation of the Daleks or induce them to develop into less aggressive creatures. The messenger also gave the Doctor a Time Ring, which he could use to get back to his TARDIS. Upon their arrival on Skaro, the Doctor, Sarah Jane and Harry was caught up in a war between the Kaleds and Thals, with the Doctor being taken prisoner by the Kaleds with Harry after being separated from Sarah Jane. While being questioned, the Doctor met the creator of the Daleks, a scientist named Davros, attempting to genetically engineer the Kaleds as the effects of their weapons caused them to mutate, seeking to evolve their mutations into a perfect form. Despite respecting each other as scientists, the Doctor was unable to convince Davros to change the Daleks into better creatures.

When he revealed he knew of several defeats of the Daleks in the future due to faults in their design, the Doctor was forced to tell Davros of each failure the Daleks suffered, so that he could prevent them. Attempting to gauge the extent of his insanity, the Doctor posed a question to Davros, asking him what he would do if he possessed the power to end all other life. Davros's willingness to utilise such power horrified the Doctor, tempting him to cut off his life supports as a last resort of stopping his plans, but he was prevented from doing so by Nyder, and he was imprisoned. Escaping, the Doctor destroyed Davros' recording of the foreknowledge, thus keeping the future from changing for the worse.

The Doctor found little other option left than to ensure the Daleks would never exist, and had the opportunity to blow up the stock of embryonic Daleks that Davros had produced. However, he questioned if he had the right to destroy the Daleks, knowing that wiping out an entire species would make him just like them, and the fear of the Dalek had caused many worlds to ally with each other. With this in mind, the Doctor allowed the Dalek species to persist, and chose to stall their rise to power instead. Failing to listen to the Doctor's warnings, Davros found his own creations usurping him. Because they were programmed to acknowledge any creature as inferior to the Dalek, they deemed him unworthy to rule them. Fleeing after the Daleks killed Davros, the Doctor buried them and their factory underground, delaying their progression by a thousand years. (TV: *Genesis of the Daleks*)

The Doctor, Harry, and Sarah Jane returned to the Space Station Nerva earlier in its timeline, when it orbited Jupiter, which had a fifty-year assignment to guide space freighters. The TARDIS was travelling back through time to them, leaving them stranded until it arrived. While waiting for it to arrive, the Doctor became involved with stopping a Cyberman attack on Voga, the planet of gold, to keep the resource of their major weakness to a minimum in the Cyber-Wars. The Doctor ultimately stopped them from blowing up the planet, defeating them once more. Finally reunited with the TARDIS, the Doctor received a call for help from the Brigadier via a space-time telegraph. (TV: *Revenge of the Cybermen*)

### Returning to UNIT

The Doctor, Sarah and Harry met up with the Brigadier, and discovered that an alien race known as the Zygons were planning to use a Skarasen to attack London and abducting people to power body-prints that let them shape-shift into the forms of humans as disguises, the disappearance of the Duke of Forgill being among them. The Doctor and company had several close calls with the Zygons and eventually discovered the location of their spaceship, rescuing everyone, during which, the Doctor instigated the ship to self-destruct.

Discovering the plan was to have the Skarasen besiege Stanbridge House in a display of power, the group made haste to London. As the Brigadier and UNIT took care of the surviving Zygon commander, Broton, the Doctor found the trilanic activator used to control the Skarasen's movement and gave it to the Skarasen, who ate it and returned to Loch Ness. The Doctor prevented the destruction of the city, though the monster was still seen by the populace, and the Brigadier would have to quietly cover up the incident. After returning to Scotland to retrieve the TARDIS and bring the Duke back home, Harry chose to leave the TARDIS and find a more conventional means of transportation, while the Doctor managed to persuade Sarah to stay. (TV: *Terror of the Zygons*)

### Journey to London

The Doctor and Sarah Jane next landed on Zeta Minor, thirty-thousand years in the future. Accused of killing the crew attempting to mine the planet for alternative sources to replace their dying sun, the Doctor instead found that the planet was the boundary between the normal universe and the anti-matter universe; taking any mineral from the planet would trap a ship there. The crew's leader, Professor Sorenson, had been infected with anti-matter and was fighting off its influence as he kept changing back and forth into a monster that mummified living beings. The Doctor tricked Sorenson into the TARDIS and kicked him into the pool of anti-matter, releasing the expedition ship and restoring the professor to normal. (TV: *Planet of Evil*)

Attempting to return to UNIT, the Doctor instead arrived at a priory in 1911, on the future site of UNIT headquarters. There, he had to prevent the last of the Osirans, Sutekh, from escaping his prison in Egypt and destroying the universe. Though unsuccessful in stopping Sutekh's servant, Marcus Scarman, from releasing him, the Doctor was able to delay Sutekh's trip through a time corridor to the priory by moving the corridor's threshold to the far future, thus effectively ageing him to death. Not realising his actions would cause the thermal balance to equalise, the Doctor accidentally set the priory on fire. (TV: *Pyramids of Mars*)

Afterwards, the Doctor seemingly found himself in a town Sarah Jane had previously visited for a newspaper article. They ultimately found that it was a facsimile of the town, not even actually on Earth, populated by androids under the control of the Kraals. The Kraals' own world had become uninhabitable, leading them to plan on wiping out Earth's population with a virus, then populating the planet themselves. Discovering Sarah had been replaced by an android, the Doctor found and rescued her. With the help of Harry Sullivan and UNIT, the Doctor was able to stop the aliens and rescue the townsfolk the Kraals replaced. (TV: *The Android Invasion*)

The Doctor and Sarah boarded the *Space Station Abraxas* sometime in the 29th century and helped to re-stabilise the ship during an attack from the Sontarans, led by Major Raal. Whilst the Doctor was going to leave, Raal and his second in command Srik managed to transmat aboard, having been partially converted into Cybermen and ordered to destroy the Doctor's timeline. Evading them for a short while and attempting to save members of the crew that were in the Sontaran's line of sight, the Doctor was saved by the timely presence of his previous incarnation, Liz Shaw and Bernice Summerfield, the latter of whom had been sent by his future self to prevent the Cybermen from wiping out his timeline. Benny gave the Doctor the order to rendezvous at Old Marley, which the Doctor and Sarah obliged in doing.

Upon arrival, the Doctor convened with his third, fifth, sixth, seventh and eighth incarnations inside the church, reconnecting with the Brigadier in the process. He helped the Doctors and their companions in fending off the Cybermen and helped to telepathically turn the Cybermen's time capsules into time bombs, leading evacuation measures with his sixth incarnation shortly afterwards. Once the threat had been dealt with, the Doctor and Sarah Jane departed. (TV: *Destiny*)

### Final adventures with Sarah

The Doctor found his TARDIS forced to land on Karn by the Time Lords, as the Sisterhood of Karn had been crashing ships that passed Karn to protect what was left of their Elixir of Life. The Doctor used a firecracker to unplug the crevice the elixir came from, being promptly booted out. He then discovered the evil Time Lord Morbius was being resurrected in a patchwork body. Defeating him in battle of mindbending, the Doctor managed to reduce Morbius to a mindless beast that tumbled off a cliff to his death. However, the Doctor was left severely drained, but the Sisterhood allowed him to drink some their elixir, which restored the Doctor's health. (TV: *The Brain of Morbius*)

Being summoned by UNIT on behalf of the World Ecology Bureau, the Doctor saw pictures of a pod discovered in Antarctica. The Doctor and Sarah were flown to Antarctica, and found that the pod was Krynoid and had infected Charles Winlett. Outside, they also found another pod, and put it in the freezer. Before they could do anything for Winlett, he mutated further and became aggressive, going on a rampage. While trying to stop the new Krynoid, the Doctor failed to stop Scorby and Keeler, who worked for Harrison Chase, from finding the other pod, and escaping with it.

After the Krynoid was destroyed by Scorby's bomb, the Doctor and Sarah were rescued, and brought back to England. Investigating Chase Manor, the Doctor and Sarah encountered the Krynoid, who had infected Keeler, and had taken control of the body of Harrison Chase, planning to spread its seeds to take over Earth. While fighting Chase, the Krynoid and the plants animated by the creature, the Doctor called in UNIT, who worked with the RAF to destroy the Krynoid and the manor along with it. (TV: *The Seeds of Doom*)

The Doctor and Sarah visited London to find that the Pescatons were invading Earth. The Doctor discovered their weakness to high-pitched noise and set a trap for their leader, Zor, killing him. When he died, all the other Pescatons died as well. (AUDIO: *Doctor Who and the Pescatons*)

During a trip in space, the Doctor accidentally brought the Helix Intelligence to San Martino, Italy, in the 15th century, where it planned to dominate the human race by using the Brotherhood of Demnos as its agents. Because the agents had been converted into pure energy beings by the Helix, the Doctor tricked the Brotherhood's leader, Hieronymous, into using all his energy until he vanished. Using his mask and cloak, the Doctor posed as him and used a device to drain the energy out of the rest of the Brotherhood, killing them and saving the Earth. (TV: *The Masque of Mandragora*)

The TARDIS landed in an English quarry, where it was buried by an explosion. The Doctor emerged unscathed, but Sarah was taken ill and so he accompanied her to hospital. There, he discovered she had come into contact with a stone hand and, when Sarah stole the hand and fled, followed her to Nunton Experimental Complex. Her wearing of a ring brought her under the control of Eldrad, a Kastrian scientist. The Doctor used a cooling duct to reach Sarah and brought her to her senses.

Eldrad restored herself using the reactor core. The Doctor agreed to take her back to Kastria, her homeworld, but only in the present, not her home time, as this broke the Laws of Time. On Kastria, Eldrad was injured by an acid-laden booby trap, so the Doctor and Sarah had to conduct her to a regenerator chamber. There she was restored to her male form. Eldrad discovered his people to be dead and asked the Doctor to return him to Earth so he could rule over humanity. Fleeing from him, the Doctor made use of his scarf, with Sarah holding the other end, to trip Eldrad, who fell into an abyss.

Back in his TARDIS, the Doctor received a telepathic summons from Gallifrey and was forced to leave Sarah behind, just as she herself had decided to return home. They both agreed they wouldn't forget one another as Sarah left. (TV: *The Hand of Fear*)

### Return to Gallifrey

Discovering that the signal hadn't come from someone he knew, the Doctor returned to Gallifrey, just as it was the time of the election for Lord President, and theorised that the departing President was in danger. Stealing a robe to blend in, the Doctor attempted to prevent an assassination, but ended up framed for murdering the Lord President. To keep himself from being executed, the Doctor declared his own candidacy for Lord President. Believing the Matrix would give him clues as to who was behind this, the Doctor ended up in a mental duel with the culprit.

After finding the assassin, the Doctor learned that it was Goth, another Lord President candidate, who was being manipulated by the Decayed Master; since their last meeting, the Master, with no regenerations left, had degenerated into a rotting corpse. The Master was plotting to use the Eye of Harmony in an attempt to restart his cycle of regenerations by using the Sash of Rassilon to protect himself from the effects of the Black hole that would destroy Gallifrey as a side-effect.

After failing to convince the Master that, since the sash was damaged in the death of the old president, it would put the Master at risk, the Doctor fought him off. Though the Master managed to escape capture, the Doctor left his former teacher, Borusa, to lead Gallifrey as Cardinal, (TV: *The Deadly Assassin*) though, as the only candidate left, he was still eligible to gain the title of Lord President, even after leaving. (TV: *The Invasion of Time*)

Sometime after this, The Doctor watched Leonardo da Vinci paint the *Mona Lisa*, thinking the model was a "dreadful woman with no eyebrows who wouldn't sit still". (TV: *City of Death*) He also met Albert Einstein and tried to explain the realities of his Theory of relativity, but Einstein insisted that "he knew best." (TV: *The Stones of Blood*)

### First adventures with Leela

The Doctor returned to the planet colonised by the Mordee expedition centuries before, where he found that he was remembered as an evil god called "the Evil One" by the descendants of the colonists. Descendants of the colonist's survey team had become a warrior tribe called the Sevateem, while descendants of the technicians had become a technologically advanced tribe called the Tesh. Infiltrating the "Sacred Heart" of the old Mordee expedition ship with the help of one of the Sevateem, Leela, the Doctor cured the computer Xoanon of his multiple personalities. Leela, wanting to come with the Doctor, forced her way into the TARDIS, becoming his new companion. (TV: *The Face of Evil*)

On a Sandminer in the 23rd century, the Doctor and Leela were accused of killing members of the crew, and taken prisoner. They later discovered a madman named Taren Capel was murdering the crew, hoping to help his robot "brethren" rule humanity. However, the Doctor turned Capel's reprogramming of the robots against him by using helium gas to make his voice unrecognisable to them, leading to his death. (TV: *The Robots of Death*)

The Doctor brought Leela to Victorian London and the pair encountered the magician Li H'sen Chang and his master, the self-styled Weng-Chiang, who was actually the 51st century criminal Magnus Greel. With the help of Henry Gordon Jago and Professor George Litefoot, the Doctor was able to stop Greel from using a failed time machine that would have destroyed reality, but when the attempt happened without a crucial part, Greel was caught in an explosion. (TV: *The Talons of Weng-Chiang*)

At a lighthouse on Fang Rock, the Doctor and Leela discovered a Rutan Host who was planning to make use of the Earth's strategic placement in its race's war with the Sontarans. After all but he and Leela were killed by it, the Doctor destroyed the Rutan by blowing up the lighthouse. (TV: *Horror of Fang Rock*)

### Adopting K9

The Doctor, having become the host of the Nucleus, travelled to the Bi-Al Foundation medical centre in the year 5000, where its Swarm spread further, infecting numerous others. The Nucleus brought itself out of the Doctor's body and into the macro world to hatch more offspring. The Doctor travelled to Titan Base, where a hive of Swarm lay. The Doctor mixed the oxygen canisters with the methane atmosphere of Titan, blowing up the base and killing the Swarm. While there, he brought along Professor Marius' robot dog, K9, to fight the Swarm-infected humans. Unable to return to Earth with K9, Marius gave K9 to the Doctor as a gift. (TV: *The Invisible Enemy*)

The Doctor traced the source of a time hole to a group of scientists experimenting on a mysterious skull called Eustace. Much to his horror, the Doctor discovered "Eustace" was actually the skull of a Golden Core, responsible for creating humanity's darker side. Believing it could give them the power to rule the world, a cult used the scientist Thea Ransome as a medium for "Eustace". The cult's plan backfired, as the core simply began transforming them into Fendahl. The cult's leader, Maximillian Stael, committed suicide, preventing them from reaching the quota of thirteen Fendahl. The Doctor blew up their base, killing the transformed humans. (TV: *Image of the Fendahl*)

Arriving at Megropolis One on Pluto in the far future, the Doctor learned of the Company responsible for over-taxing the populace. He then discovered that Usurians had previously helped humanity move to Mars and then to Pluto for resources, but planned to leave them behind once Pluto was drained. He overthrew their representative, the Collector, trapping him in a jar in his true form of "seaweed", and set up a better economy. (TV: *The Sun Makers*)

Reaching the edge of the universe, the Doctor met a species the Time Lords helped evolve, whose destruction of their own planet because of their advancement in evolution led to the Time Lords' non-interference policy. He helped them locate and rescue fellow descendants of their species, taking them a new planet where they could start a better life. While helping them, the Doctor battled against the Oracle, a machine that enslaved the secondary descendants with the aid of robots. (TV: *Underworld*)

### Lord President of Gallifrey

Returning once more to Gallifrey, and posing as vainglorious and power-mad, the Doctor sought and attained the office of Lord President from Borusa, who he had left in charge on his previous visit, as part of a scheme to save his home world from an invasion force of the Vardans who had contacted him for his aid. He was unable to confide his intent to double cross the Vardans in anyone but K9 due to the Vardans’ psychic abilities. He was inaugurated as President and crowned with the Crown of Rassilon, painfully connecting him to the Matrix.

As part of his plan, he had Leela exiled from the Citadel so that she would gather a resistance force. As he’d planned the Vardans arrived in force after K9 lowered Gallifrey’s transduction barrier, enabling him to track their point of origin and contain it in a time loop. However he was the confronted by an advance party of Sontarans who had used the Vardans’ invasion to gain access to Gallifrey. He retreated into the TARDIS and picked the Sontarans off through traps he set for them. Realising they would be unable to control Gallifrey, the Sontarans sought to destroy it so the Doctor was forced to retrieve the De-mat gun and use it to erase their leader, Stor, from history.

With his homeworld protected and Borusa once again in charge, the Doctor planned to resume his travels. But he learned Leela had fallen in love with a Gallifreyan guard named Andred and wished to remain with him; K9 likewise wished to stay with his "mistress". Though he seemed sad at first to lose both companions, the Doctor quickly pulled out a crate marked "K9 Mark II" from a storage area and grinned to himself. (TV: *The Invasion of Time*)

### Quest for the Key to Time

After completing repairs on K9, the Doctor was called upon by the White Guardian to find the Key to Time's pieces and assemble it to bring the universe into balance. For his quest, the Doctor was given a new companion by the guardian, a Time Lady named Romanadvoratrelundar, whom the Doctor decided to call Romana. Despite not being too fond of each other, they managed to find the first segment to the Key on Ribos, which was disguised as a piece of Jethrik two con artists were using in their schemes. (TV: *The Ribos Operation*)

They set out to find the second segment on Calufrax, but instead landed on Zanak, where they became caught in the middle of a revolution between pirates, led by the Captain, and the psychically gifted Mentiads, who grew in number each time their planet materialised over another for riches and resources. Defeating the Captain and his nurse, the Doctor revealed to Romana that Calufrax, which was being held as a miniaturised trophy, was the second segment. (TV: *The Pirate Planet*)

The Doctor and Romana next journeyed to Boscombe Moor, where they found the third segment as a necklace belonging to the intergalactic criminal Cessair of Diplos, who had been posing as an ordinary Earth woman for centuries after she had stolen the segment while it was the Great Seal of Diplos, and used its transformative powers to take on different forms. Entering a ship stuck in hyperspace above a stone circle, the Doctor found her jailers and, as they did not know what she looked like, tricked them into identifying her, and they imprisoned her in the form of a stone. The Doctor then sent them through hyperspace to their intended destination. (TV: *The Stones of Blood*)

While looking for the fourth segment on Tara, the Doctor decided to take a relaxing fishing break while Romana went to look for it. Though successful in finding the piece to the Key, they both were forced into the political power struggle on Tara, as Romana was identical to a princess being held captive by Count Grendel, who wished to use her to claim the throne before his cousin. The Doctor exposed Grendel's plans and went on his way with Romana to continue the search. (TV: *The Androids of Tara*)

The search for the fifth segment brought the Doctor and Romana to Delta III where the Swampies worshipped an overgrown squid called Kroll, who was attacking a human mining base. Putting himself in harm's way, the Doctor found Kroll had swallowed the segment of the Key and was transformed by its properties. Allowing himself to be grabbed by the giant creature, the Doctor was able to use the tracer to reclaim the segment, transforming Kroll back into smaller squids in the process. Reclaiming the piece, the Doctor and Romana returned to search for the last segment. (TV: *The Power of Kroll*)

Searching for the final segment brought the Doctor and Romana to Atrios, a war-torn planet being attacked by the nearby computer-planet Zeros. There, they met the Shadow, an agent of the Black Guardian. Unfortunately, the final segment was in the form of Princess Astra of Atrios. The Doctor completed the Key, and then quickly separated it back into its original components to prevent the Black Guardian from getting it. Fearful the Black Guardian would return for revenge, the Doctor installed a randomiser in the TARDIS controls. (TV: *The Armageddon Factor*)

### The new Romana

While repairing K9, the Doctor found Romana had regenerated into Astra's form, much to his displeasure. The randomiser landed the TARDIS on Skaro, where the Daleks were excavating the remains of the Kaled base to restore Davros. The Doctor also faced the Movellans, an android race at war with the Daleks. Having reached an impasse of logic, they both needed someone to reprogram their respective computers for "illogical" movements that would give either side an advantage. Winning the Movellans over, the Doctor allowed them to take Davros in cryogenic custody to await trial for his crime of creating the Daleks. (TV: *Destiny of the Daleks*)

The Doctor partially bypassed the randomiser to take Romana on a relaxing holiday to Paris, where the Doctor discovered a Jagaroth named Scaroth was splintered into twelve selves throughout time after his spaceship exploded; the explosion's radiation affected the primordial ooze, thus beginning life on Earth. The Doctor, Romana and detective Duggan succeeded in stopping Scaroth from preventing his spaceship from exploding. (TV: *City of Death*)

The Doctor later received a distress signal and arrived on Chloris, a lush and verdant world with only small quantities of metals, all of which were controlled by its ruler, Lady Adrasta. The Doctor was sent for execution, but managed to avoid it, deciding to investigate the creature he was supposed to be fed to. He found it to be an imprisoned Tythonian that had been sent by its people to set up a trade agreement with Chloris. Deciding to end Adastra's tyranny, the Doctor allowed the Tythonian to kill her and let a new reign of peace be set up between the two species of the planet. (TV: *The Creature from the Pit*)

The TARDIS then arrived on the space liner *Empress*, which had become locked together with a private ship, the *Hecate*, after colliding with it upon emerging from hyperspace. The Doctor and Romana met Tryst, who had a Continuous Event Transmuter machine. However, some Mandrels from Eden had somehow gotten on board. The Doctor later discovered he had been lied to, and Mandrels actually decomposed into the addictive drug vraxoin. The Doctor thwarted the drug-smuggling plan of Tryst and the pilot of the *Hecate*, separated the two ships, and returned the Mandrels to Eden. (TV: *Nightmare of Eden*)

Whilst in the middle of conducting TARDIS repair, the Doctor and Romana were caught in the middle of a sacrificial ceremony for a "god" called the Nimon. They discovered that this "god" was actually a parasite alien preparing Skonnos for the rest of its species. The Doctor succeeded in preventing the teleport from bringing more than two extra Nimon before the Nimon killed themselves as an accidental side-effect to their final gambit. With the help of the Anethans originally sent to be life-force sacrifices for the transporter, the Doctor destroyed the remaining Nimon before departing with Romana. (TV: *The Horns of Nimon*)

### Shada

The TARDIS was sent a distress signal from Cambridge in 1979, sent by a retired Time Lord known as Professor Chronotis. (PROSE: *Shada*) Sources diverge on when and how their trip ended; the Doctor and Romana were kidnapped (TV: *The Five Doctors*), but were soon returned and saw the Professor as planned. (PROSE: *Shada*; HOMEVID: *Shada*)

While they were on a punt up the Cam, the Doctor and Romana were taken by a time scoop to the Death Zone on Gallifrey, but were caught in a time eddy and failed to arrive in the Death Zone. (TV: *The Five Doctors*) They were returned to the Cam (HOMEVID: *The Five Doctors*) to the time they left (HOMEVID: *Shada*) when Borusa was sealed in the Tomb of Rassilon. (TV: *The Five Doctors*)

According to the accounts where the pair were returned to the moment they left, the Doctor met Chris Parsons and Clare Keightley, who helped him to fight Skagra. Skagra attempted to steal The Worshipful and Ancient Law of Gallifrey so he could break into Shada and retrieve Salyavin from his imprisonment. Without realising that Salyavin had escaped, and was living in retirement under the alias "Chronotis", the Doctor had to foil Skagra's plot, which involved taking Salyavin's power to project his mind into other minds, so he could use it to shift his mind into the minds of all life in the universe, using his Krargs. After defeating Skagra, the Doctor imprisoned him in his own ship, and decided to allow Salyavin to remain on Earth. (PROSE: *Shada*; HOMEVID: *Shada*)

### Final voyages with Romana

After their holiday at Brighton, the Doctor took the TARDIS to the Leisure Hive, due to Romana's urging for a technologically advanced place of relaxation. However, during the adventure to repair a rejuvenation machine, the Doctor ended up ageing hundreds of years. A genetically created Argolin, named Pangol, decided to take over, but thanks to the Doctor's interference, his plan to create a clone army of himself backfired as the Doctor was in the machine beforehand, gaining his youth back. However, the Doctor, deciding that he was tired of running from his enemies, had to remove the randomiser in order to repair the machine. (TV: *The Leisure Hive*)

Arriving on Tigella, a planet he visited centuries earlier, the Doctor was accused of stealing the Dodecahedron, but was saved from punishment when it was discovered someone was posing as him. He discovered Meglos, last of the Zolfa-Thurans, had stolen the object to power a device that could destroy planets. The Doctor stopped Meglos by redirecting his machine's laser back at it, destroying him. While preparing to leave for a new adventure, the Doctor received a message from Gallifrey, demanding the return of Romana. (TV: *Meglos*)

### Trapped in E-Space

While on course to Gallifrey, the TARDIS fell through a Charged Vacuum Emboitment and into a smaller pocket universe known as E-Space. Landing on Alzarius, the Doctor met the Alzarians, who were trying to repair their ship. Romana was bitten by an Alzarian spider, falling into a trance; under its control, she allowed the Marshmen to invade. However, they were driven back out by an increase of oxygen, which was poisonous to them. Studying these species' genetics, the Doctor found that the Marshmen killed the original humanoids and evolved to replace them. Creating an antidote, the Doctor cured Romana and taught the Alzarians how to pilot their ship. During this time, he met a precocious Alzarian boy named Adric, who snuck on board the TARDIS before they left to find a way back home to their universe as there was nothing left on Alzarius for him. (TV: *Full Circle*)

After discovering Adric had stowed aboard his TARDIS, the Doctor and Romana next arrived on the most technologically advanced planet in E-Space, where they learned of a human ship called the *Hydrax* that came there several years ago. They met the Three Who Rule, discovering their castle was actually the *Hydrax* and they were vampires, converted by the Great Vampires' king, an old nemesis of the Time Lords. During the Time of Arising, in which the King would be resurrected and return to N-Space, the Doctor launched an escape craft from the *Hydrax* through its heart, killing the ancient creature. After this, the Doctor set off to return Adric home, as well as to find a way back into his own universe. (TV: *State of Decay*)

While travelling through E-Space to take Adric home, the Doctor ended up at the Gateway, a location directly between N-Space and E-Space, and time winds blew into the TARDIS, damaging K9 while he was attempting to land. While at the Gateway, the Doctor found Tharils being mistreated by a man named Rorvik in his desire to leave the limbo between realities. When Rorvik's final attempt to leave backfired, it cost him his life. Upon finding the way home, the Doctor discovered Romana wished to remain to help the Tharils. Saddened, the Doctor agreed to let her do so with K9 as a parting gift. As Adric never had any intention of returning home to Alzarius, the Doctor allowed him to stay aboard the TARDIS and return to N-Space with him. (TV: *Warriors' Gate*)

### Return to N-Space

Back in N-Space, the Doctor was called by the Traken Union's Keeper to assist him in keeping evil away while his power waned from age, and a replacement was found. He encountered Nyssa of Traken and her father, Tremas, when he and Adric were accused of wishing to take the Source for themselves. The Doctor eventually discovered the Decayed Master was attempting to steal the Source, planning to use its power to merge with him to get a new body. However, the Doctor turned the tables on him again, leaving the Master to perish in his exploding TARDIS. (TV: *The Keeper of Traken*)

### Death

Tired of the TARDIS' chameleon circuit being stuck, the Doctor went to Logopolis to obtain the formula needed to fix it. Arriving, the Doctor found a woman named Tegan Jovanka had accidentally boarded the TARDIS during a brief trip to Earth, thinking it was a police box. He also reunited with Nyssa, whilst also meeting a being known as the Watcher; they had a secret conversation and the Doctor learnt the Watcher was a manifestation of his next incarnation and that he would be regenerating soon. Realising his end was near, the Doctor got the formulas from Logopolis and shrunk the TARDIS by accident due to the Master's interference, but this was corrected. The Doctor then went to the Pharos radio telescope to a broadcast the CVE signal as the Watcher took Adric and Nyssa outside the universe.

After successfully reopening the CVEs, the Doctor's short-lived alliance with the Master ended when the Doctor attempted to stop him from forcing the universe into serving the Master with the threat of weaponising the entropy. Pulling the plug on the radio that powered the dish to do so, the Doctor ended up hanging onto it as the Master rotated the dish. Dangling from the dish, the Doctor experienced visions of past foes before he lost his grip and fell to the ground.

In a daze from the fall, the Doctor experienced visions of the Brigadier, Benton, Sarah, Harry, Leela, K-9 and Romana. When Adric, Nyssa and Tegan gathered around him, the Doctor smiled, telling them that the moment had been prepared for. Shocking everyone present, the Doctor held his hand out to the Watcher, who merged with the Doctor as he regenerated into his next incarnation. (TV: *Logopolis*)

### Undated Events

* The Fourth Doctor challenged a computer to ask him questions about Australia, as the Doctor believed he was highly knowledgeable. The Doctor was actually unaware of the harm that pollution was causing to Australia, and so, he decided to go to Australia to help. (TV: *Dr. Who For Keep Australia Beautiful*
* The Fourth Doctor and Azmael had an encounter in which Azmael drank so much that the Doctor had to throw him into a pool to sober him. (TV: *The Twin Dilemma*)

## Other realities

### Aborted timelines

Under the influence of the Valeyard and the Dark Matrix, the Fourth Doctor was corrupted into destroying the Daleks at their very beginning. This timeline was negated when the Ninth Doctor defeated the Valeyard and released the Dark Matrix from his control. (TV: *Matrix*)

## Personality

Seeing all sapient lifeforms are his "kith", (TV: *Pyramids of Mars*) the Fourth Doctor would instinctively put his own wants aside to go against all the odds to protect even his enemies from harm, (TV: *Revenge of the Cybermen*, *The Seeds of Doom*, *The Invisible Enemy*, *Underworld*) regardless of their social standings, (TV: *Warriors' Gate*) wishing that the peoples of the universe would just "get along". (TV: *Full Circle*)

He delighted in keeping both friends and foes alike off guard with oddball humour and curious pranks, often playing the fool to lull his opponents into underestimating him, (TV: *The Invasion of Time*, *City of Death*) but he genuinely believed that there was "no point being [a] grown-up if you [couldn't] be childish sometimes". (TV: *Robot*) He always tried to stay "one step ahead of [his] enemies", (TV: *The Talons of Weng-Chiang*) as he was "a very dangerous fellow when he [didn't] know what [he was] doing." (TV: *Destiny of the Daleks*) However, when in an emergency, the Doctor would get straight to the point and ask only the most important questions. (TV: *The Ark in Space*, *Genesis of the Daleks*, *Pyramids of Mars*, *The Deadly Assassin*, *Destiny*)

He thrilled on seeing new sights, (TV: *The Robots of Death*) claiming he "wouldn't sleep at night" if he never learnt where he had been, (TV: *Destiny of the Daleks*) and delighted in getting himself into trouble, (TV: *Genesis of the Daleks*) often delivering the most frightening of news in a cheery tone and with a smile on his face. (TV: *Terror of the Zygons*, *The Seeds of Doom*, *Horror of Fang Rock*, *Destiny*)

Although he was generally peace-loving and kind-hearted, the Doctor would react with explosive fury when provoked. (TV: *The Sontaran Experiment*, *Pyramids of Mars*, *The Brain of Morbius*, *The Seeds of Doom*, *The Pirate Planet*, *Full Circle*) He "always [got] rude when [he was] trying to cover up a mistake", (TV: *Planet of Evil*) and could indulge in cultural insensitivity when feeling short-tempered. (TV: *Horror of Fang Rock*)

The Fourth Doctor thought himself as being "a wise and wonderful person who want[ed] to help", (TV: *The Power of Kroll*) and enjoyed being the centre of attention, sometimes getting someone to ask him questions solely so he could show off his intelligence by answering them. (TV: *The Talons of Weng-Chiang*) He believed highly in himself and his brainpowers, (TV: *Robot*, *The Ark in Space*, *The Invisible Enemy*, *The Invasion of Time*, *Destiny*) though was not completely devoid of modesty. (TV: *Genesis of the Daleks*, *The Face of Evil*, *Destiny of the Daleks*, *Destiny*) He could get so deep in thought that he completely drowned out the world around him. (TV: *Robot*, *The Masque of Mandragora*, *The Hand of Fear*, *The Stones of Blood*)

Viewing "one solid hope [as] worth a cartload of certainties", (TV: *Warriors' Gate*) the Doctor held a strong determination, believing that there was "no such word as can't", (TV: *Robot*) that "nothing [was] hopeless", (TV: *The Seeds of Doom*) and that there was "always a way out" of a situation. (TV: *The Armageddon Factor*) He would openly antagonise his enemies as an act of defiance, (TV: *Revenge of the Cybermen*, *The Brain of Morbius*, *The Sun Makers*, *Underworld*) though would also charm someone in order to get them to open up for him to extract needful information. (TV: *Robot*)

He could be literal-minded, (TV: *The Seeds of Doom*, *The Stones of Blood*, *Nightmare of Eden*) and tried to "always accept the unexpected". (TV: *The Leisure Hive*)

Nearing the end of his life, the Doctor became more sombre and weary at the universe, (TV: *Logopolis*) preferring sitting back and relaxing than adventuring, (TV: *The Leisure Hive*) and becoming more vulnerable and less defiant towards peril, (TV: *Meglos*, *Warriors' Gate*, *Logopolis*) even being willing to return to Gallifrey when the Time Lords summoned him, (TV: *Full Circle*) though he was also bitter towards the lack of control he had over his life. (TV: *Logopolis*) He also had less fear for consequences, such as removing the randomiser and forgoing its protection from the Black Guardian's revenge due to feeling he was no longer a threat to him. (TV: *The Leisure Hive*)

Viewing it as "a free cosmos", (TV: *Robot*) the Fourth Doctor held a consistently anti-authoritarian attitude, with little tolerance for the bureaucracy of military protocol and police procedures, (TV: *The Seeds of Doom*, *The Talons of Weng-Chiang*, *Nightmare of Eden*) seeing himself as a free agent who was "just having fun", (TV: *Nightmare of Eden*) but held a begrudging respect for the White Guardian. (TV: *The Ribos Operation*)

Not only was he more inclined towards a solitary existence, (TV: *The Face of Evil*, *The Ribos Operation*) such as wishing to be left alone when he had a task to complete, (TV: *The Sontaran Experiment*) the Doctor also emphasised his distance from humanity, (TV: *Pyramids of Mars*) though also stated that he found mankind to be his favourite species, (TV: *The Ark in Space*, *The Masque of Mandragora*) describing them as "indomitable" for having "survived flood, famine and plague" and "cosmic wars and holocausts", (TV: *The Ark in Space*) but also acknowledged that when they "[got] together in great numbers, other lifeforms sometimes suffer[ed]". (TV: *The Invisible Enemy*) He also generally maintained his distance from the Time Lords, and resented that they were capable of controlling his travels whenever they pleased, (TV: *Genesis of the Daleks*, *The Brain of Morbius*, *The Creature from the Pit*) as he "[didn't] like not knowing where [he was] going to turn up next". (TV: *The Leisure Hive*)

He was almost completely devoid of fear, reacting unfazed to threats of pain, (TV: *The Sun Makers*, *City of Death*) and assassination attempts, (TV: *Robot*, *The Android Invasion*, *The Robots of Death*, *The Talons of Weng-Chiang*, *Destiny*) friendlily greeting threats to his safety. (TV: *The Sontaran Experiment*, *Terror of the Zygons*, *The Android Invasion*, *The Talons of Weng-Chiang*, *The Stones of Blood*, *The Androids of Tara*, *The Creature from the Pit*, *The Horns of Nimon*) However, he did fear the powers of the Wirrn, (TV: *The Ark in Space*) Sutekh, (TV: *Pyramids of Mars*) the Fendahl, (TV: *Image of the Fendahl*) and the Black Guardian. (TV: *The Armageddon Factor*) When it seemed he was doomed, he resolved to accept his fate, lamenting the long life he had lived (TV: *The Power of Kroll*) and the friends he had with him. (TV: *The Horns of Nimon*)

He liked to drink ginger beer (TV: *The Android Invasion*) and eat oranges. (TV: *The Masque of Mandragora*)

He liked bumblebees, (TV: *The Robots of Death*) "concise answers", (TV: *City of Death*) ghost stories, (TV: *State of Decay*) and punting. (TV: *The Five Doctors*)

Among his favourite times was 1911. (TV: *Pyramids of Mars*) He also had a great appreciation for art and antique furniture. (TV: *City of Death*)

He "hate[d] goodbyes", instead preferring to "just slip away quietly". (TV: *Robot*) He also disliked guided tours, (TV: *The Seeds of Doom*) the colour white, (TV: *The Invisible Enemy*) and "gimmicky gadgets". (TV: *The Ribos Operation*)

The Doctor had little patience for "religious gobbledygook" (TV: *The Face of Evil*) and "superstitious rubbish". (TV: *The Talons of Weng-Chiang*) He also tried to avoid being certain of things, as he thought it "a sign of weakness", (TV: *The Face of Evil*) as there was "enough uncertainty in the universe" for one to "never guess unless [they had] to." (TV: *Logopolis*) He considered failure to be "one of the basic freedoms". (TV: *The Robots of Death*)

He looked down on computers, deeming them to be "sophisticated idiots" due to how they "[did] exactly what [someone told] them [to do] at amazing speed[s]" while being "very difficult [at] stop[ping] [from] obeying the original order" if told to stop, (TV: *Robot*) and also admonished them for lacking imagination. (TV: *The Invisible Enemy*)

He considered his lucky numbers to be 7 (TV: *The Power of Kroll*) and 740,384,338. (TV: *The Creature from the Pit*) He enjoyed playing games such as draughts (TV: *The Talons of Weng-Chiang*) and chess. (TV: *The Sun Makers*, *The Androids of Tara*)

Despite his charm and offbeat humour, the Fourth Doctor could be intensely brooding, serious and even callous at times, (TV: *Pyramids of Mars*, *The Seeds of Doom*, *The Deadly Assassin*, *Horror of Fang Rock*) and would keenly scrutinise his surroundings even when playing the fool. (TV: *Genesis of the Daleks*, *Revenge of the Cybermen*, *Destiny of the Daleks*, *Destiny*) He was not against taking a life in extreme circumstances, (TV: *The Sontaran Experiment*, *The Brain of Morbius*, *The Invasion of Time*, *The Ribos Operation*, *The Armageddon Factor*, *Meglos*) but would scold Leela for unnecessary killings. (TV: *The Face of Evil*)

In his darker moments, the Doctor threatened to deactivate Davros' life-support machine to coerce him into destroying the Daleks, (TV: *Genesis of the Daleks*) fatally electrocuted an attacking Tesh under Xoanon's control, (TV: *The Face of Evil*) handed Maximillian Stael a gun with the knowledge he would use it for suicide without much convincing, (TV: *Image of the Fendahl*) and seemed to have nothing against Leela killing random attackers, as long as she kept quiet about it. (TV: *The Talons of Weng-Chiang*) He was also willing to sacrifice himself in order to kill Davros via an explosive device in an attempt to prevent the Daleks harnessing their creator. (TV: *Destiny of the Daleks*)

Though he was much less inclined to use physical violence than his predecessor, the Fourth Doctor would react aggressively if he had no alternative but to defend himself. (TV: *The Seeds of Doom*, *The Deadly Assassin*, *Nightmare of Eden*) However, he would try to see if he could reason with his opponents before he resorted to force. (PROSE: *Doctor Who and the Genesis of the Daleks*)

While he voiced a dislike for guns, (TV: *Pyramids of Mars*) and claimed he would never use one, (TV: *The Seeds of Doom*) he was willing to use the likes of the De-mat Gun and Earth firearms if necessary, (TV: *The Seeds of Doom*, *The Deadly Assassin*, *The Talons of Weng-Chiang*, *Image of the Fendahl*, *The Invasion of Time*) though preferred to improvise a non-lethal way of escaping a situation, (TV: *The Face of Evil*) making a point to never carry a weapon so as not to give reason for people to harm him. (TV: *The Robots of Death*)

Nevertheless, the Doctor still had a strong moral code, such as confronting J.P. Kettlewell about how the ends never justified the means, (TV: *Robot*) telling Sorenson that scientists "buy [their] privilege[s] to experiment at the cost of total responsibility" for the outcome, (TV: *Planet of Evil*) and admonished harming an innocent for science as nothing short of "coldblooded murder". (TV: *Full Circle*) When ready to destroy the Daleks before the creation, the Doctor hesitated when he realised he would be no better himself than the Daleks if he committed genocide against them. (TV: *Genesis of the Daleks*) He was also appalled at the actions of the Captain, (TV: *The Pirate Planet*) and refused to listen to Tryst's attempts to justify drug-running in order to fund his scientific work, simply telling him to go away. (TV: *Nightmare of Eden*)

However, when the situation called for it, the Doctor could be ruthless in how he acquired results, (TV: *Revenge of the Cybermen*, *The Face of Evil*) and become particularly brutish in how he subdued his opponents. (TV: *The Seeds of Doom*) He did not take kindly to his friends being physically attacked, (TV: *The Face of Evil*) and also scolded a Tharil for unprovokedly knocking down a servant. (TV: *Warriors' Gate*) He also despised how greed drove people to complicate a situation. (TV: *The Seeds of Doom*)

The Doctor was not above the occasional act of hypocrisy, such as telling Harry Sullivan that it was a waste to throw something away, immediately before disregarding a piece of metal that had saved his life. He also told Harry it was "a mistake to clutter one's pockets", despite he himself keeping a large variety of things in his own pockets. (TV: *The Sontaran Experiment*) He later took an instant liking to Romana's second incarnation when she mimicked his dress sense, despite previously telling her that "external appearances weren't important". (TV: *Destiny of the Daleks*) He was also unwilling to admit to any wrongdoing on his part. (TV: *The Sun Makers*)

He was also not averse to deliberately angering his companions as a motivation for them to achieve a task to prove him wrong, (TV: *The Ark in Space*) nor was he above winding then up on occasion, such as fooling Leela into playing with a yo-yo for an extended period of time, with her believing it was a form of magic, (TV: *The Robots of Death*) or causing Romana to panic when he pretended to be corrupted by the Key to Time. (TV: *The Armageddon Factor*)

He thought his third incarnation was "arrogant" when he met him, whilst the Third Doctor described him as being a "demented bohemian". (TV: *Destiny*)

Because he did not like the responsibility of looking after them, (TV: *The Ribos Operation*) the Fourth Doctor would rarely invite others to travel with him, a majority of his companions inviting themselves aboard the TARDIS, (TV: *Robot*, *The Face of Evil*, *State of Decay*) or having someone else persuade the Doctor to let them join him. (TV: *The Invisible Enemy*, *The Ribos Operation*, *Logopolis*) Nevertheless, the Doctor had a close friendship with his companions, and would be crestfallen when they left him. (TV: *Terror of the Zygons*, *The Hand of Fear*, *The Invasion of Time*, *Warriors' Gate*)

He considered Sarah Jane Smith and K9, and implicitly Leela, to be his best friends. (TV: *The Seeds of Doom*, *Underworld*) However, he viewed Harry Sullivan as an imbecile, (TV: *Revenge of the Cybermen*) and believed that any intelligence that Harry showed was entirely due to his influence. (TV: *The Ark in Space*)

He tended not to display romantic feelings, being mostly oblivious to other people's attractiveness, believing that telling Countess Scarlioni that she was "probably beautiful" was a compliment, (TV: *City of Death*) although he acknowledged that Romana was attractive in her first incarnation. (TV: *The Pirate Planet*)

Unlike his predecessors, the Fourth Doctor did not maintain a close working relationship with UNIT, keeping his distance from the organisation except for a handful of occasions, reacting with anger and disdain whenever he was recalled back to Earth by the Brigadier. (TV: *Terror of the Zygons*, *Pyramids of Mars*) Nonetheless, he reacted with happiness upon meeting a retired Brigadier at Old Marley. (TV: *Destiny*)

The Fourth Doctor "usually[ got] on terribly well with children." (TV: *Full Circle*)

Commander Stevenson openly wondered if the Fourth Doctor was "quite right in the head", with Harry Sullivan agreeing that he had his "absent minded moments", (TV: *Revenge of the Cybermen*) and Richard Dunbar asking if he was "quite sane". (TV: *The Seeds of Doom*)

Leela described the Doctor as being "very difficult sometimes, but he [had] great knowledge and gentleness." (TV: *Image of the Fendahl*) According to K9 Mark I, a number of people described the Doctor as "the most insufferably arrogant, overbearing, patronising bean tin." (TV: *The Invasion of Time*)

In her first incarnation, Romana diagnosed him with having "massive compensation syndrome", (TV: *The Ribos Operation*) stating that he was "capricious, arrogant, self-opinionated, irrational, and [didn't] even know where [he was] going". (TV: *The Armageddon Factor*)

After seeing himself being observed by the Watcher, the Doctor became aware his end was nearing, adopting a resigned mood while vowing to stop the Master, eventually losing the strength to keep his grip on the Pharos Project radio telescope's gantry, and fell to his death. As he lay dying, the Doctor spent his last moments thinking of his past companions, and then explained to his present friends that the moment of his regeneration had been prepared for, with a serene glance and a final grin. (TV: *Logopolis*)

### Habits and Quirks

The Fourth Doctor would often have jelly babies with him, and offered them as a greeting or peace offering. (TV: *Robot*, *The Ark in Space*, *The Face of Evil*, *The Robots of Death*, *The Talons of Weng-Chiang*, *Image of the Fendahl*, *The Sun Makers*, *The Invasion of Time*, *Destiny of the Daleks*, *Nightmare of Eden*, *The Horns of Nimon*, *Destiny*) His personal favourites were the orange coloured jelly babies. (TV: *The Invasion of Time*)

The Fourth Doctor would also let out aloud, *"Ah"*, when he came to a realisation, (TV: *Robot*, *The Sontaran Experiment*, *Terror of the Zygons*, *The Hand of Fear*, *The Deadly Assassin*, *The Invasion of Time*, *The Pirate Planet*, *The Armageddon Factor*, *The Horns of Nimon*, *The Leisure Hive*) noticed something of interest, (TV: *The Ark in Space*, *Genesis of the Daleks*, *Planet of Evil*, *The Brain of Morbius*, *The Face of Evil*, *The Talons of Weng-Chiang*, *The Invisible Enemy*, *Image of the Fendahl*, *The Ribos Operation*, *The Stones of Blood*, *City of Death*, *Meglos*, *State of Decay*) needed to explain himself, (TV: *The Ark in Space*, *The Stones of Blood*, *State of Decay*) or as a response to someone's explanation. (TV: *The Face of Evil*, *The Robots of Death*, *The Invasion of Time*, *The Ribos Operation*, *The Stones of Blood*, *The Androids of Tara*, *The Armageddon Factor*, *Dr. Who For Keep Australia Beautiful*, *City of Death*, *The Creature from the Pit*, *Meglos*, *State of Decay*, *The Keeper of Traken*, *Logopolis*, *Destiny*) He would say, *"Ah, there you are"*, when he noticed that someone had entered his presence or where someone was. (TV: *Genesis of the Daleks*, *Terror of the Zygons*, *The Androids of Tara*, *The Horns of Nimon*)

He would often say, "come on", when instructing his companions to follow him, as he believed saying it marked him as "the one who leads". (TV: *Image of the Fendahl*) He would also say, "come along", for a similar reason. (TV: *Robot*, *Genesis of the Daleks*, *The Brain of Morbius*, *The Seeds of Doom*, *The Talons of Weng-Chiang*, *The Stones of Blood*)

The Doctor often talked to himself, (TV: *Robot*, *The Ark in Space*, *Pyramids of Mars*, *The Face of Evil*, *The Invasion of Time*, *The Stones of Blood*, *State of Decay*) or acted like he was interacting with someone that wasn't there, (TV: *The Face of Evil*, *Image of the Fendahl*, *The Invasion of Time*, *Dr. Who For Keep Australia Beautiful*, *The Creature from the Pit*, *Warriors' Gate*) with Sarah Jane Smith stating he did so "mostly because [he was] the only person who [knew] what [he was] talking about". (TV: *The Ark in Space*)

He would say, "well...", whenever he was about to explain something, (TV: *The Ark in Space*, *Terror of the Zygons*, *The Brain of Morbius*, *The Hand of Fear*, *The Face of Evil*, *The Invisible Enemy*, *Image of the Fendahl*, *Underworld*, *The Invasion of Time*, *The Stones of Blood*, *City of Death*, *The Leisure Hive*, *The Keeper of Traken*, *Logopolis*) and would often interrupt himself with a, "still...", when attempting to explain something and wanted to elaborate on what he was talking about. (TV: *Robot*, *The Ark in Space*, *The Pirate Planet*)

Whenever he heard something he didn't like, he would shout, "what". (TV: *Genesis of the Daleks*, *The Brain of Morbius*, *The Talons of Weng-Chiang*, *The Invisible Enemy*, *The Sun Makers*, *Underworld*, *The Invasion of Time*, *The Ribos Operation*, *The Pirate Planet*, *The Androids of Tara*, *Dr. Who For Keep Australia Beautiful*, *Destiny of the Daleks*, *City of Death*, *Nightmare of Eden*, *The Horns of Nimon*, *The Leisure Hive*, *State of Decay*, *Warriors' Gate*, *The Keeper of Traken*, *Destiny*)

When reaching a conclusion, he would utter, "of course". (TV: *The Ark in Space*, *Revenge of the Cybermen*, *Terror of the Zygons*, *Image of the Fendahl*, *The Pirate Planet*, *The Stones of Blood*, *The Armageddon Factor*, *Destiny of the Daleks*, *Nightmare of Eden*, *The Horns of Nimon*, *The Leisure Hive*, *Meglos*, *State of Decay*, *Logopolis*) When met with a concept he rejected, he would describe the ideas as "rubbish". (TV: *The Sontaran Experiment*, *The Hand of Fear*, *The Deadly Assassin*, *The Sun Makers*, *The Ribos Operation*, *The Pirate Planet*, *The Armageddon Factor*)

The Doctor would say, "splendid", when celebrating a positive outcome, receiving good news or describing a place he liked, (TV: *The Ark in Space*, *Revenge of the Cybermen*, *Pyramids of Mars*, *Image of the Fendahl*, *The Pirate Planet*) and often quoted literature. (TV: *Revenge of the Cybermen*, *Planet of Evil*, *The Android Invasion*, *The Face of Evil*, *The Robots of Death*, *The Talons of Weng-Chiang*, *Horror of Fang Rock*, *The Power of Kroll*, *State of Decay*, *Warriors' Gate*)

He would often ask others if they were listening to him, (TV: *The Android Invasion*, *The Seeds of Doom*, *The Invasion of Time*, *The Armageddon Factor*) and would tell people to "shut up" when he was concentrating. (TV: *Terror of the Zygons*, *The Face of Evil*, *The Sun Makers*, *Underworld*, *The Invasion of Time*, *The Stones of Blood*, *Destiny of the Daleks*)

He frequently called those who annoyed him with their perceived poor planning and clumsiness an "idiot", (TV: *Robot*, *The Ark in Space*, *The Deadly Assassin*, *The Androids of Tara*, *City of Death*) and would often describe an inhumane adversary as an "unspeakable abomination". (TV: *The Sontaran Experiment*, *The Brain of Morbius*)

The Fourth Doctor was prone to boggling his eyes out while flashing his upper teeth in a grin. (TV: *Robot*, *The Ark in Space*, *Genesis of the Daleks*, *Revenge of the Cybermen*, *Terror of the Zygons*, *The Seeds of Doom*, *The Masque of Mandragora*, *The Deadly Assassin*, *The Face of Evil*, *The Robots of Death*, *The Talons of Weng-Chiang*, *The Sun Makers*, *The Invasion of Time*, *The Pirate Planet*, *Destiny of the Daleks*, *City of Death*, *The Creature from the Pit*, *Meglos*, *State of Decay*, *The Keeper of Traken*, *Destiny*)

When he was not pushing back the ends of his coats to put his hands in his trouser pockets, (TV: *Horror of Fang Rock*, *Image of the Fendahl*, *Underworld*, *The Ribos Operation*, *The Power of Kroll*, *The Armageddon Factor*, *Destiny of the Daleks*, *City of Death*, *The Creature from the Pit*, *The Horns of Nimon*, *Dr. Who For Keep Australia Beautiful*, *Destination: Holocaust*) the Doctor would instead rest his knuckles on the pockets' edges. (TV: *The Ark in Space*, *Genesis of the Daleks*, *The Android Invasion*, *The Brain of Morbius*, *Horror of Fang Rock*, *The Sun Makers*, *The Stones of Blood*, *The Armageddon Factor*) Other times, he would place his hands in the pockets of his coat, especially with his burgundy jacket. (TV: *The Leisure Hive*, *Meglos*, *Full Circle*, *State of Decay*, *The Keeper of Traken*, *Logopolis*)

The Doctor tended to run his hand through his hair when concentrating on something, (TV: *The Ark in Space*, *Genesis of the Daleks*, *Pyramids of Mars*, *The Seeds of Doom*, *The Masque of Mandragora*, *The Invisible Enemy*, *The Invasion of Time*, *The Stones of Blood*, *The Armageddon Factor*, *City of Death*) or to calm himself after moments of intensity. (TV: *Revenge of the Cybermen*, *The Masque of Mandragora*, *The Pirate Planet*, *The Androids of Tara*, *The Creature from the Pit*)

When in thought, he would scratch at his thumb with his teeth. (TV: *Robot*, *Planet of Evil*, *Pyramids of Mars*, *The Android Invasion*, *The Creature from the Pit*) To allure a sense of mystery, the Doctor would often tap his nose when keeping secrets. (TV: *Robot*, *The Brain of Morbius*, *The Creature from the Pit*)

When relaxing, the Doctor tended to put his feet up on a ledge and lean back, often placing his hat over his face as he dowsed off. (TV: *Robot*, *Terror of the Zygons*, *The Seeds of Doom*, *Image of the Fendahl*, *The Invasion of Time*, *The Androids of Tara*) He tended to lightly smack himself when he came to a realisation. (TV: *Robot*, *The Invasion of Time*, *The Armageddon Factor*, *State of Decay*)

The Fourth Doctor also started a trend of talking to the TARDIS, (TV: *The Deadly Assassin*, *The Robots of Death*, *Image of the Fendahl*, *The Horns of Nimon*) constantly showing affection for his magnificent machine by kissing it and caring for it when it got damaged. (TV: *The Invisible Enemy*, *The Invasion of Time*, *The Ribos Operation*)

When complimenting his female companions' achievements, the Doctor would say, "good girl". When confused, he would give a quiet, "eh". He frequently rubbed his index finger under his nose. He often whistled to himself. He would shush people to get them to be silent. He would sometimes react with dread to a name, only to then admit he had never heard of the person. He frequently said, "I see", when responding to someone. He would pull at his face when in thought. He sometimes drooped his face.

The Doctor would play with a yo-yo to relax or help determine new environments, (TV: *The Ark in Space*, *Revenge of the Cybermen*, *The Android Invasion*, *The Brain of Morbius*, *The Seeds of Doom*, *The Masque of Mandragora*) and also carried a small telescope that he sometimes used to assess his surroundings. (TV: *City of Death*, *State of Decay*)

According to one account, the Fourth Doctor always carried a piccolo on his person, telling Sarah that he "always played the piccolo when [he was] nervous" to "relieve the tension". (AUDIO: *Doctor Who and the Pescatons*)

### Skills

Much like his immediate predecessor, the Fourth Doctor was very physical, being talented at evasive manoeuvres, (TV: *Robot*, *Revenge of the Cybermen*) an excellent runner, (TV: *Genesis of the Daleks*, *Terror of the Zygons*, *The Seeds of Doom*) and a skilled hand-to-hand fighter. (TV: *The Seeds of Doom*, *The Masque of Mandragora*, *The Talons of Weng-Chiang*, *Logopolis*, *Destiny*) He was also capable of rendering someone unconscious with a single blow, (TV: *Genesis of the Daleks*, *Planet of Evil*, *The Seeds of Doom*, *The Hand of Fear*, *The Power of Kroll*, *City of Death*, *State of Decay*, *The Keeper of Traken*) and was briefly able to tussle with a Mandrel. (TV: *Nightmare of Eden*)

Showing incredible accuracy, the Doctor was able to effortlessly throw a gun to Harry with a baton, (TV: *Genesis of the Daleks*) hit a bullseye on a dart board, (TV: *The Android Invasion*) strike a strand of rope with a crossbow, (TV: *The Face of Evil*) throw an axe at Magnus Greel's distillation machine to free Leela, (TV: *The Talons of Weng-Chiang*) and land his hat on a Dalek eyestalk. (TV: *Destiny of the Daleks*)

He was also shown to be a highly skilled swordsman, (TV: *The Masque of Mandragora*, *The Androids of Tara*) even when using a club as a substitute blade. (TV: *The Sontaran Experiment*)

The Fourth Doctor possessed telepathic powers, allowing him to project his mind over long distances to communicate with other telepathic users. (TV: *The Pirate Planet*) Due to his "complex mind", he was able to immunise himself from other telepaths. (TV: *The Invasion of Time*) He was also able to overpower Morbius in a mindbending duel, though his victory left him severely weakened, with only the Elixir of Life being able to revive him. (TV: *The Brain of Morbius*) He was also able to convert to Cyberman time capsules into highly powerful time bombs, though only with the help of his other selves. (TV: *Destiny*)

Claiming to be a master hypnotist, (TV: *The Talons of Weng-Chiang*) the Fourth Doctor was able to use hypnosis on people with simple eye contact, (TV: *Terror of the Zygons*) by laying his hands on their temples (TV: *The Hand of Fear*) or with well-chosen vocal commands. (TV: *The Face of Evil*, *The Sun Makers*, *The Invasion of Time*) Other times, the Doctor would instead use a fob watch to hypnotise someone. (TV: *The Talons of Weng-Chiang*, *The Ribos Operation*)

He could repair an android. (TV: *The Androids of Tara*)

The Doctor could still drive Bessie, (TV: *Robot*) was able to commandeer and ride a horse with ease, (TV: *The Masque of Mandragora*) and could pilot an aircar. (TV: *The Pirate Planet*)

The Doctor could speak Mandarin and Cantonese, among other dialects. (TV: *The Talons of Weng-Chiang*)

Like several of his incarnations, the Fourth Doctor's pockets appeared to be dimensionally transcendental, as he carried a large array of bizarre items in his pockets. (TV: *Robot*, *Genesis of the Daleks*, *Revenge of the Cybermen*, *The Talons of Weng-Chiang*) He could also hold his breath for an extended period of time by using a technique taught to him by a Tibetan monk, (TV: *Terror of the Zygons*) and was talented with sleight of hand pickpocketing. (TV: *The Ribos Operation*, *City of Death*)

If his mind came under attack, the Doctor could force himself into a healing coma. (TV: *The Invisible Enemy*, *The Invasion of Time*) He could judge character keenly, almost instantly knowing whom not to trust. (TV: *The Power of Kroll*, *City of Death*)

The Doctor could also easily draw caricatures of people, (TV: *The Deadly Assassin*) perform magic tricks, (TV: *The Talons of Weng-Chiang*) and produce a scream powerful enough to shatter glass. (TV: *The Power of Kroll*)

## Appearance

The Fourth Doctor was notable for having large, expressive blue eyes, a large hooked nose, a round chin, bright white teeth and a large head of wild curly brown hair, (TV: *Planet of the Spiders*, *Robot*) leading him to frequently be described as being "all teeth and curls". (TV: *The Five Doctors*) He had short, light brown hairs growing on his arms. (TV: *Robot*)

By the time he was given his quest for the Key to Time by the White Guardian, the Doctor's hair had started to turn grey, and he had acquired a small scar on his upper lip, (TV: *The Ribos Operation*) which was made worse after he banged his face on the TARDIS control console, (TV: *The Pirate Planet*) though it soon faded. (TV: *The Stones of Blood*)

Upon first seeing his reflection, the Doctor lamented that "nothing [was] perfect", and that he had to "take the rough with the smooth", but thought his "nose [was] a definite improvement", though remained unsure about his ears in comparison. (TV: *Robot*)

Li H'sen Chang described the Fourth Doctor as "tall with wide pale eyes and hair that curls like the ram", (TV: *The Talons of Weng-Chiang*) with Mena describing him as a "tall curly-headed humanoid". (TV: *The Leisure Hive*) Adric also called the Doctor a "tall man with curly hair and a silly scarf." (TV: *State of Decay*) Professor Frederick Marius remarked that the Doctor looked like a "space vagrant". (TV: *The Invisible Enemy*)

### Clothing

#### Main attires

The Fourth Doctor's most distinctive item of clothing was a series of long, rainbow-styled scarfs that varied in length and pattern formation, (TV: *Robot*, *Image of the Fendahl*, *The Ribos Operation*, *Shada*) which had originally been knitted for him by Madame Nostradamus. (TV: *The Ark in Space*) His dark curly hair was often partially hidden by a floppy brown fedora. (TV: *Robot*)

Aside from his scarf, the Doctor's first outfit consisted of a rust-orange corduroy blazer with elbow patches, a dark brown cardigan with diamond shapes adorning the front, a white dress shirt, an emerald green skinny tie, ankle-high leather shoes and baggy grey tweed trousers (TV: *Robot*) held up by braces. (TV: *The Ribos Operation*) He later switched his jumper for a checked-styled waistcoat and discarded his tie altogether, (TV: *Terror of the Zygons*) until he replaced it with a cravat. (TV: *Planet of Evil*) Eventually, his switched his blazer for a frock coat. (TV: *Pyramids of Mars*) After switching his cravat for an ascot tie, (TV: *The Seeds of Doom*) he eventually abandoned neck wear in favour of an open-necked shirt, (TV: *Image of the Fendahl*) with a likewise unbuttoned waistcoat, as well as a white ascot tied around his neck. (TV: *The Invasion of Time*)

He wore several frock coats of different colours, including a burgundy coat, (TV: *Pyramids of Mars*) a light grey beige tweed coat, (TV: *The Android Invasion*) and a dark brown coat. (TV: *The Power of Kroll*) He sometimes adorned his coats with lapel pins and brooches in various shapes, such as a flock of geese, (TV: *The Power of Kroll*) or an artist's pallet with tubes of paint. (TV: *City of Death*) He also varied his footwear to include leather boots, (TV: *The Deadly Assassin*) ugg-style boots, (TV: *The Face of Evil*) and green knee-high wellington boots, (TV: *The Power of Kroll*) and also changed his usual style to a purple waistcoat, (TV: *The Ribos Operation*) brown checkered trousers, (TV: *The Power of Kroll*) and a yellow, checkered waistcoat. (TV: *City of Death*) He would also switch his braces for a black belt. (TV: *Destiny of the Daleks*)

Towards the end of his life, the Doctor overhauled his outfit to a full-length maroon coat, waistcoat, trousers, buccaneer-style leather boots, a Poet's Hat, an ecru open-neck dress shirt with subtle ecru question marks adorning the collars, and a burgundy scarf (TV: *The Leisure Hive*) He kept his trousers up with a pair of braces with a flowery design. (TV: *Meglos*)

The Doctor occasionally wore trench coats, such as a light brown one with dark brown trim, (TV: *The Ark in Space*) and a plum velvet one. (TV: *The Leisure Hive*) He also had a black jeweller's scope, (TV: *Robot*) and had a pair of small-lensed, dark-tinted glasses that he could wear when tinkering with scientific equipment. (TV: *The Sun Makers*)

#### Other Costumes

The Doctor briefly wore a light brown checkered coat, a dark brown waistcoat with a red floral pattern, a brown chekcered overcoat and a deerstalker hat in a Shelock Holmes-esque get-up whilst in 19th century London. (TV: *The Talons of Weng-Chiang*)

## Other Information

### Age

While on Earth, the Doctor stated his age to be 749 years. (TV: *The Seeds of Doom*)

## Behind the Scenes

### Casting

Actors considered for the role of the fourth incarnation included Michael Bentine, Bernard Cribbins, Graham Crowden, Fulton Mackay and Jim Dale. Tom Baker was cast based on his role as the villain Koura in *The Golden Voyage of Sinbad*.

### Appearance

According to the creators of the show and Baker, the character's look was originally based on paintings and posters by Henri de Toulouse-Lautrec of his friend, Aristide Bruant, a singer and nightclub owner whose trademark was a black cloak and long red scarf.

### Possible romances

Since the fourth incarnation was the youngest in appearance at the time, he therefore appeared closer in age to his companions. This led to concerns being expressed of possible "hanky panky in the TARDIS", a term often used in the tabloid press to suggest the impression of off-screen dalliances between the various Doctors and their young, female companions.

Perhaps to address this, according to the Information Text commentary on the 2007 DVD release of *The Stones of Blood*, Baker generally tried to emphasise the asexuality of the character, apart from possible subtle romantic tension such as that with Sarah Jane Smith. Despite this, Baker was not above tossing in occasional visual jokes that suggested sexual tension.

For example, in *The Stones of Blood* the Doctor and Romana have to huddle close in order to be within the confines of a transporter beam and enter what would, in normal circumstances, be seen as a romantic clinch, but neither character appears to recognise this. Likewise, the Doctor and Romana are forced into close proximity in *The Ribos Operation* when hiding from Graff Vynda-K and neither seem to recognise this as a romantic moment.

### In popular culture

The fourth incarnation's distinctive appearance and mannerisms have made him a target for affectionate parody. The character appeared several times on *The Simpsons* and twice on *Robot Chicken*. Even in 2011, a full 30 years after he left his tenure as the Doctor, an animated parody of his incarnation appeared an episode of *Futurama*. In *Hugo 2: Whodunnit?*, a computer game, the player's character can save Tom Baker's Doctor from a Dalek, who in return gives the player his sonic screwdriver.

He was frequently impersonated by impressionist Jon Culshaw on the radio and television series *Dead Ringers*. Even *Barney Miller* had an episode featuring an eccentric man claiming to be a time-traveller and wearing a long striped scarf. Archival footage of the fourth incarnation's first title sequence was also used in the *Family Guy* episode "Blue Harvest" to represent and parody *Star Wars*' hyperspace.

Tom Baker, as the narrator of the series *Little Britain*, has referenced *Doctor Who*. He also appeared in *Doctor Who and the Daleks in Seven Keys to Doomsday*, a stage play that opened two weeks before Baker began his tenure as the Doctor. In the play, Trevor Martin plays an alternative version of the fourth incarnation.

In the book *Return of the Bunny Suicides*, there was a scene in which a bunny sits on top of the TARDIS with a noose around its neck as the fourth incarnation runs into it, being chased by a Dalek.

Peter Jackson wore a costume similar to the fourth incarnation's when he played Derek in his film *Bad Taste*.

On *The Big Bang Theory*, in the episode, "The Justice League Recombination", Stuart wears the Fourth Doctor's costume to a New Year's Eve costume party at his comic book shop.

The video game *Team Fortress 2* features the Fourth Doctor's scarf and hat as cosmetics for the Medic class. The items were renamed as the Chronoscarf and Das Ubersternmann. The hat was the first item added in the game in a 2013 patch while the scarf was not added until a year later in the 18 June 2014 update.

### Reprising the role

Unlike his predecessors Patrick Troughton and Jon Pertwee or his successors Peter Davison, Colin Baker and Sylvester McCoy, Tom Baker was notoriously hesitant to reprise the role of the Doctor. Originally intended as a major player in the 20th-anniversary special, *The Five Doctors*, Baker pulled out before production began, citing other obligations as his reasoning. The production team rewrote the scripts to give much of his role to the Fifth Doctor, and included the Fourth Doctor by making use of unbroadcast footage from *Shada*. A Madame Tussauds wax mannequin of his incarnation was used in publicity shots to keep the "five Doctors" concept afloat.

In 1993, Baker was hired to play the Doctor full-on for the 30th anniversary special, *Destiny*. Around this time, he also introduced a VHS reconstruction of *Shada*, though not apparently in character as the Doctor. In 1997 he returned to the role in a more serious manner in a Superannuation advertisement. He also appeared as Tom Baker as Fourth Doctor in the comedy docudrama Who on Earth is Tom Baker.

Despite his hesitancy to play the role again, Baker made frequent appearances on DVD releases of his stories, recording audio commentaries for many and conducting on-camera interviews for others.

In the 2000s, Baker made a tentative step towards reprising the role by agreeing to record audio books for BBC Audio, reading the texts from several Target novelisations from his era.

### Other matters

The Fourth Doctor became the first incarnation not to have any of the master tapes for his episodes wiped by the BBC, as his were the latest in the show's history, leaving the older tapes more prone to reuse.
