Given a new lease of life by the Time Lords with the intention of having him fight in the Last Great Time War, the Master initially tried to manipulate the conflict to suit his own goals.

However, after his failure to properly use the Heavenly Paradigm, the Master was driven to such a state of terror that he fled to the end of the universe and turned himself into a human baby with a chameleon arch to escape the Time Lords and wait out the conflict.

After spending many years living as a humble human scientist on Malcassairo, the Master's personality was reawakened by Martha Jones, and he made to steal the Doctor's TARDIS from the Tenth Doctor, but was fatally shot by Chantho, the Malmooth assistant to his human persona, and forced to regenerate into.

Post-regeneration
At some point, the Master regenerated into his seventeenth incarnation, (PROSE: Girl Power!) and, as he always did after a regeneration, visited the Scoundrels Club to better recover from the regeneration process. (PROSE: Dismemberment)

Early escapades
At some point, the Master designed a laser screwdriver for his own personal use. (AUDIO: The Heavenly Paradigm)

Scheming on Callous
The Master was employed by Narvin to go to the planet Callous to find the rare metal Swenyo. The Master went to Callous and began manipulating Elliot King, and eventually his daughter, Cassandra, to mine the Swenyo. Eventually, due to his extreme guilt and the effects of the Swenyo, Elliot committed suicide. (AUDIO: Call for the Dead) Cassandra and her wife, Martine, went to Callous to rebirth the mining process, with aid from Ood miners and the Master in disguise. Due to the Master's aid, the mining process was a success, and Cassandra found an extremely concentrated amount of Swenyo, which the Master managed to acquire for himself by contacting the Teremon, the people that the King family worked for. (AUDIO: The Glittering Prize)

With Martine, the Master took the Swenyo to an asteroid, but Martine was driven mad by the physic properties of the Swenyo, and jumped off the asteroid to her death. (AUDIO: The Persistence of Dreams) After being captured by the Teremon, the Master escaped and weaponized the Ood to prevent the further mining of Swenyo. The Master then collected his Swenyo and gave it to Narvin, who gave the Master a Chameleon Arch in exchange. (AUDIO: Sins of the Father)

Joining the Time War
The Master was eventually recruited by the Time Lords to fight in the Time War, as they foresaw he would be the "perfect warrior" for such a conflict. (TV: The Sound of Drums) Though he was able to write out most of his involvement in the Last Great Time War between the Time Lords and the Daleks, (COMIC: The Judas Goatee) the Master fought in the battle over Keetol and helped the Time Lords make one of their first victories. (AUDIO: The Heavenly Paradigm) He was also present at the Siege of the Chronotide, and found himself screaming for the General's mercy when the Multiform closed in. (PROSE: Lords and Masters)

Working for the CIA
During the Time War, the Master created the War Seeds, biological weapons designed to convert the population of entire planets into warrior species faithful to the Time Lords. (AUDIO: War Seed)

Responding to a distress call from his secret base, the Master encountered Liv Chenka, posing as a Time Lord agent while she told him about the alliance between the Eleven and the Ravenous. Investigating events at the Crucible of Souls, the Master realised that the Eleven had used the Crucible and the Matrix print of the Gallifreyan scientist Artron to give the entire universe the ability to regenerate, making them all potential food for the Ravenous. Working with and their, the War Master was able to give the Eighth Doctor the opportunity to "heal" the Ravenous while the Masters used the Crucible to restore the rest of the universe to mortality. Although the Time Lords requested Artron's Matrix print to give them the ability to grant new regeneration cycles to Time Lords, the Masters first used this to restore the "Decaying" Master to life with a new regeneration cycle. (AUDIO: Day of the Master)

Creating the Rage
On the Time Lords' orders, the Master spent years creating the ultimate biological weapon. He set up a facility on Xenotopia and personally recruited scientists. (AUDIO: Darkness and Light) His first subject was Alice Pritchard, a chronopsycho who had been adopted on Earth. (AUDIO: The Survivor) He next captured Giuseppe Sabatani from 1890s America. (AUDIO: The Coney Island Chameleon)

He implanted a crew member of River Song's expedition on the Utorpy with an ancient alien egg, with the cooperation of her partner. As it reached gestation, the Master picked off the crew, but River prevented him from obtaining control of the creature and set the ship to self-destruct. Together, they escaped in an escape pod and, upon crashing, the Master hypnotised her to forget he had been there. (AUDIO: Concealed Weapon)

For the final element, the Master lured the Doctor by tricking Alice into summoning him telepathically. Alice inadvertently drained the Doctor psychically, leading to him collapsing whilst he confronted the Master. He killed Alice, having served her purpose. The Master had tissue extracted from the Doctor (AUDIO: The Missing Link) and implanted a device in his head. The Master's work culminated in the creation of the Rage; the ultimate biological weapon. A CIA agent implanted within the Master's staff attempted to seize the creature, accidentally unleashing it in the process. The Master arranged the Doctor's escape, believing he would be able to tame with the creature. The Rage pursued and eventually absorbed them both, with the Doctor proving insufficient to tame it. Together, the Doctor and the Master were able to overwhelm the creature, resulting in it perishing and releasing them both. The Master fled, using the device in the Doctor's head to wipe his memories of their encounter. (AUDIO: Darkness and Light)

A lost regeneration


At some point during the Time War, the Master regenerated into the body of. (COMIC: The Organ Grinder)

After having his TARDIS brought into the Time War from the future by Alice Obiefune, (COMIC: The Organ Grinder) the "Child" Master tried to escape from the Cyclors with it, unintentionally causing a paradox by using a TARDIS from an aborted timeline. When mixture with the Psilent songbox worsened the paradox, the Master was forced back into his War incarnation, and lost all memory of his aborted successor due to the paradox. (COMIC: Fast Asleep) The Master's TARDIS recorded that the Master fled the event horizon in his TARDIS before the Doctor's plans were carried out, deeming them too insane even for him. (COMIC: The One)

Avoiding the Time War
While "exploring possibilities", the Master became stranded in a parallel dimension; when this dimension was invaded by the Cybermen of the Cyber-Mainframe, who originated from an alternate universe and sought to upgrade the multiverse, the Master used the opportunity to obtain Cyber-Technology to repair his TARDIS and followed the Cybermen back into N-Space. The Master landed his TARDIS, urgently in need of repairs, on Fortress Island on Earth during the 2010s, where the Cybermen, who had begun an invasion of Earth, attempted to cyber-convert him and Kate Stewart, but the two escaped with Josh Carter.

With his TARDIS stolen by the Cybermen, the Master collaborated with Kate, Josh, Vikram Shindi and Sam Bishop and returned to Fortress Island. At the base, the Master was seemingly converted into the "Cyber-Master" by the virtually-converted Petronella Osgood, granting him the opportunity to destroy the Cybermen by expanding their dimension gate to draw power from all the parallel Earths the Cybermen had failed to convert. After removing his Cyber-faceplate, the Master used the remaining contaminated energy to return in his TARDIS to "the fray" of the war, (AUDIO: Master of Worlds) leaving behind a Wirrn egg as a parting gift to UNIT. (AUDIO: Hosts of the Wirrn)

Escapades in the Time War
During the Time War, the Master fought the Supreme Dalek on the slopes of the Never Vault, (TV: The Witch's Familiar) and considered it a worthy opponent, even showing disappointment when the Dalek Emperor didn't send it to locate him on Arcking. (AUDIO: The Good Master)

A plot to change history
On the planet Mussafa, the Master pretended to help resolve an energy crisis, with the help of another Time Lord named Crazlus. The Master built a device designed by Crazlus that was capable of harnessing the energy of Mussafa's sun, and used it to power his TARDIS, allowing him and Crazlus to leave while all life on the planet was destroyed. The Master praised Crazlus, and decided to bring him back to Gallifrey to infiltrate the CIA. (AUDIO: He Who Wins)

After Crazlus was in a position of power in the CIA, the Master constructed a plan to interfere in the creation of the Daleks with the Anti-Genesis code. After poisoning himself with the blood of a Dolthradian Dragon, the dying Master returned to Gallifrey and requested a Time Lord funeral, though Narvin denied him and ordered Crazlus to have the Master's body burnt with the Infernal Toxicant, but Crazlus instead used the Toxicant to cure the Master from the poison. The Master then took control of Crazlus' body and went to Narvin, pretending that "Crazlus" had found the Anti-Genesis code in the Master's TARDIS computer, and tricked Narvin into leading him in to the Matrix to find the real code. Once he was in possession of the code, the Master travelled to Skaro during the Thousand Year War, and arranged for Davros to be killed during the bombardment where he was originally crippled. (AUDIO: From the Flames)

Infiltrating the Kaled scientific elite by pretending to be Davros' uncle "Sovrad", the Master became the new head of scientific development, and tricked Davros's former assistant, Elrond, into giving him Davros's last discoveries, allowing the Master to modify the Mark III travel machine into a proper Dalek casing with a biogenetic accelerator, which he used on Elrond to speed his biological evolution into a Kaled mutant, creating his first Dalek, which he sent against the rest of the Kaled elite, transforming them all into Daleks. In the midst of his work, the Master was reached by Lamarius, a Time Lord agent sent to kill him, but he captured and interrogate her, learning that she was also a renegade for using a time torpedo to avoid the destruction of a planet where her family lived, and, after infecting her with the same mutant radiation the Kaleds were affected from, sent Lamarius back to Gallifrey to mock Narvin and President Livia about her failure. (AUDIO: The Master’s Dalek Plan)

After sealing the bunker by blowing up the entrance and promoting Elrond to Dalek Supreme, the Master gave him the order to build five thousands Mark III travel machine as he used his TARDIS to move forwards in time to the moment the Time Lords sent the Fourth Doctor to interfere in the creation of Daleks. The Master set up an ambush for the Doctor and his companions and had his Daleks kill them. He then ordered the Daleks to deliver a genetic bomb to the Thals, so that they could use them against the remaining Kaleds and turn them into mutants, to be put inside the newly-built Dalek cases and form an army. (AUDIO: Shockwave)

The Master then led the Daleks into a military campaign which eventuated in his total victory over the universe. However, immediately after this victory, the Master began to have visions of another man warning him against the treason of his Daleks by showing him a vision of his extermination for behaving too much like an "inferior" being. He then revealed himself as an exiled Master from a parallel universe, brought to N-Space by the Dalek Time Strategist in an attempt to avert the War Master's changes. The "Exiled" Master convinced the War Master that theDaleks would rebel against him as they did with Davros, and the War Master agreed to help him and the Dalek Time Strategist avert his victory. He led them to Mussafa, when he originally connected Crazlus to his TARDIS, and contacted his past self to trick him into bringing Crazlus to them so that he could be killed. As a result of Crazlus's death, the Master's plan was made impossible, and the timeline resulting from his success was erased: the present Master dissolved, the Daleks from the original timeline came back into existence, and the connection between the "Exiled" Master and N-Space became tenuous.

The Daleks attempted to capture the Masters, but they escaped into the War Master's TARDIS. The Daleks went into pursuit and attacked, with their first blow causing the "Exiled" Master to fall into a wormhole in the fabric of reality. Their next strike heavily damaged the TARDIS, sending it on a crash course, while the Master was retrieved by the Daleks, who blackmailed him into serving them in exchange for the location of his lost TARDIS. (AUDIO: He Who Wins)

Recovering his TARDIS
The Daleks sent the Master to Gardezza, where he posed as the Doctor, using his reputation to gain the trust of the Gardezzans. The Master located his TARDIS on the planet and betrayed both the Daleks and the Gardezzans to retrieve it. Inside, he received a call to return to Gallifrey and left to answer it. (AUDIO: Beneath the Viscoid)

Arriving on Gallifrey, Romana II and Narvin sent the Master alongside Leela to interrogate Finnian Valentine for information on a power source for a temporal weapon he’d deployed, promising that they would pardon him for his crimes. On the planet, he and Leela found Finnian had been duplicated when the temporal weapon had torn his timeline in two and used his laser screwdriver to stun both of the Finnians. He and Leela interrogated them, to no avail, so eventually he simply threatened to kill the two Finnians until he learnt that Arcking had the power source. On the way back to Gallifrey, the Master expelled Leela into the Time Vortex and headed to Arcking to seize the power source for himself. (AUDIO: The Devil You Know)

Manipulations on Arcking
Travelling to hospital planet Arcking multiple times, the Master, under the alias "Dr. Keller", attempted to possess an ancient power, known as the Heart, that had resisted the ravages of the Time War, and even prevented unnatural death. On Arcking, the Master met Cole Jarnish, a pilot who suffered from survivor's guilt as he was the sole survivor of an incident that had killed the rest of his crew. Intrigued by his desire to help the innocent people affected by the Time War, the Master hinted to Cole that he would be able to help him realise this idea. When Arcking was eventually overrun by a Dalek invasion force, the Master saved Cole's life by bringing him along in his TARDIS as he made his escape. (AUDIO: The Good Master)

Targeting the Stagnant Protocol
After travelling with him for a while, the Master was accused of being inactive to the the Time War by Cole, and was challenged to play a more active role in assisting the people suffering under the destructive effects of the Time War. While he deflected that he was forbidden to interfere due to being a Time Lord, the Master told Cole that he would allow him a chance to save a world of his choice from destruction. Cole's choice fell on a primitive farming planet. Upon landing on the planet, the Master reminded Cole that he was not allowed to meddle directly, and so decided to take some time off to build his own vineyard and try his hand at cultivating grapes while he left Cole to his own devices. (AUDIO: The Sky Man)

Whilst running his vineyard, the Master targeted the Stagnant Protocol, creating a gateway into the time lock surrounding their civilisation. Purporting to be a Time Lord ambassador, he attempted to make inroads into the Empress' court, but all his attempts to win round nobles with promises of power proved fruitless. Over the course of his campaign, the Master encountered a rival, Calantha, who was pursuing her own ambitions and began having regular lunches with her. The Master finally managed to convince Prince Gardam that he could put him on the throne as a champion of the people, but was outmanoeuvred by Calantha, who released a tamer variant of a plague, creating a crisis which hastened her own rise to power. With Gardam banished to an outer planet on plague duties and Calantha ascending to Empress, the Master conceded he had lost, but vowed to defeat Calantha. (AUDIO: The Sincerest Form of Flattery)

The Master obtained a vial of the true plague from UNIT by manipulating Jo Jones, contaminating all her memories of her uncle by stealing his identity, even after she saw through the ruse. (AUDIO: A Quiet Night In) He experimented on the plague at a research station run by Nyssa, who he left trapped in quarantine after she deduced his true identity. (AUDIO: The Orphan)

Returning to the home world of the Stagnant Protocol, the Master unleashed the true plague and rose to the position of Regent Chancellor by aiding Calantha as the situation grew increasingly desperate. He provided a cure, though refused to reveal its composition to anyone, and grew his influence over the nobility by learning secrets the plague forced its sufferers to expose. Calantha eventually moved against him and imprisoned him, torturing him by subjecting him to her tamer form of the virus, which he had not vaccinated himself against, and depriving him of food in order to force him to reveal the cure. The Master eventually faked his death and re-emerged at the public funeral for him Calantha had arranged, exposing the truth about her recent dealings with the Daleks and closing his gateway as a Dalek fleet attempted to arrive through it. With the public turning on Calantha, the Master revealed her role in the plague and convinced her to flee in a shuttle. In the aftermath, the Master assumed control of the Stagnant Protocol, but said he would leave them to their own devices for the most part, as he was confident in their obedience. (AUDIO: Unfinished Business)

With several months having passed, the Master met up with Cole to hear about his progress, and, though he mostly kept to himself inside his vineyard, he would "accidentally" leave various supplies and tools to covertly help Cole in his endeavours. After Cole's attempt to save the peaceful population of the planet backfired when he inadvertently turned them into a race of warlike semi-robotic creatures, the Master rescued Cole from his own creations in his TARDIS and took him away from the planet, assuring Cole that he would help him to undo his mistake. (AUDIO: The Sky Man)

Activating the Heavenly Paradigm
The Master and Cole travelled to Stamford Bridge in the 1970s, where they located a Time Lord repository, and the Master revealed the reason he saved Cole's life and supported his attempt to save the people of the farming planet was to turn him into a paradox powering a paradox, with the resulting temporal energy collected in Cole to be used to power the Heavenly Paradigm. Despite Cole's pleas, the Master sacrificed him to the machine, wanting to use it to create a new timeline in the universe, and thus end the War. The plan backfired, however, and the Master unintentionally caused both the Time Lords and Daleks to win several battles they had once lost. Because of this, he then saw the Dalek Emperor take control of the Time Lords' Cruciform, which frightened him into fleeing from the Time War, which he now considered "lost".

For a time, the Master corrected and observed changes made to the Time War by the Paradigm. But, still scared and tired of the fighting, he fled to the far end of time and sent his TARDIS away to Gallifrey without him and used a Chameleon Arch to turn himself into a human baby, intending to eventually resume control of his body once the Time War had ended. (AUDIO: The Heavenly Paradigm)

Under the chameleon arch
Physically human, the Master was found as a naked child on the coast of the Silver Devastation with only an "heirloom" fob watch, which could never keep time and resulted in the Master always being late for things as he grew up under the name "Yana". Yana spent most his life moving from one refugee ship to another. Yana, having retained the Master's intellect, eventually became a professor, and became friends with another scientist, Chantho, who was thought to be the last of the Malmooth race. Together, they worked on the Utopia Project to send the remnants of humanity on Malcassairo.

Yana met the Tenth Doctor, Jack Harkness and Martha Jones when they were rescued from the Futurekind. Overhearing conversation between the Doctor and Jack about things such as time travel, Daleks, and regeneration, Yana became visibly upset. Martha drew Yana's attention to the watch in his possession and, hearing voices that commanded and entreated him, Yana opened the watch and returned to his true identity. (TV: Utopia)

Death
The Master then locked the Doctor out of Yana's lab, and opened the gate keeping the Futurekind at bay to keep the Doctor occupied as he ravaged Yana's lab. After Chantho threatened him with a gun to stop him destroying their work, the Master electrocuted her with a loose set of power cables, angered that she was never curious of the fob watch during their decades of working together, and left her for dead. However, Chantho used the last of her strength to pull a laser gun on the Master while his back was turned, and shot him in the chest before she died.

Fatally wounded, the Master slithered into the Doctor's TARDIS while the Doctor watched on and deadlock sealed the door shut to keep the Doctor out. Finding the idea of dying by the hand of "an insect and a girl" undignified, the Master decided to regenerate into a form that was as young and strong as the Doctor was. (TV: Utopia)

Alternate timelines
In an aborted timeline, the War Master was brought to the ruins of Kiameth with four of his other incarnations, as well as Kamelion and Jo Grant by accident, by the, who intended to use the Attornium to take their lives in a desperate bid for his own survival after he had unleashed a sentient entropy wave. When the Masters decided to sacrifice Jo for fun, they were interrupted by, who used the time scoop to scatter the Masters along the timeline of Kiameth, to see if any of them would find a chance of redemption by either stopping the wave or salvaging something from its aftermath.

The War Master found himself amidst the evacuation of Kiameth, where he took a woman named Carola hostage to gain entry behind a force field protecting a city, where he found his "Saxon" incarnation, who killed Carola when she recognised him as the cause of the entropy wave. The War Master then took the "Saxon" Master to the entropy wave to evaluate how unstable it was, and the two resolved to save Kiameth to end the entropy wave. However, Kamelion convinced the "Saxon" Master that the War Master was plotting against him, so he abandoned him to join forces with Kamelion against Missy. Returning to the "Saxon" Master's castle, Missy tried to convince her other incarnations to use the Attornium to stop the entropy wave by feeding on it, but the War Master, having realised that the wave was their own future incarnation, discreetly poisoned himself and his other incarnations and turned off the Attornium. The resulting paradox erased the "Saxon" Master's arrival on Kiameth, bringing the universe back to normal. (AUDIO: Masterful)

Personality
The War Master would put on a front of being kind and charming, but would drop the façade the instant it was time to act. (AUDIO: Beneath the Viscoid) When the telepathic entity, the Heart of Arcking, questioned him on whether he was truly as evil as he considered himself after reading his mind, the Master was briefly caught off-guard by the question, and hesitated momentarily in answering before he gathered himself and dismissed the notion, vehemently denying that he had any benevolent sides to his personality. (AUDIO: The Good Master) He wished to save the universe from the Last Great Time War so that he could rule over it afterwards, (AUDIO: The Heavenly Paradigm) and "enjoy [his] victory", (AUDIO: The Devil You Know) claiming that the only faction he fought for was his own person. (AUDIO: Beneath the Viscoid) Though usually calm and affable, the Master took the time to taunt a squad of Daleks when they were unable to harm him. (AUDIO: The Good Master)

While he would openly admit to allowing the destruction of individuals and places he found "dull", the Master was adamant to ensure the things he found "beautiful" would be left unharmed, such as roses. (AUDIO: Sins of the Father) He also claimed that would only destroy the universe in the hopes of building something better in its place. (AUDIO: Masterful)

The War Master was a misogynist, considering it an embarrassment to have been killed by a girl, even calling it "inappropriate". (TV: Utopia) Although, he equally held everyone in similar disregard unless it benefited him, even planets, stating he only had allegiance to himself. (AUDIO: The Good Master) He was unable to empathise with others, yawning at a mother's drive to save her race being born from her dead husband and her son. (AUDIO: Beneath the Viscoid) His disregard for others was so great that he even secretly impregnated several woman with living weapons without a care for the consequences of his actions. (AUDIO: Concealed Weapon)

The War Master found enjoyment in the death of others, even killing for his own amusement, believing the most pointless of murders to be the most "fun", (AUDIO: Master of Worlds) and enjoyed tormenting his intended victims before their demise, citing an enjoyment for a "ticking clock". He would even give them a chance at survival for further torment. (AUDIO: Concealed Weapon) He also found amusement in the misery of the Time Lords, particularly when it came to Narvin. (AUDIO: Sins of the Father)

When comparing him to the "decayed" incarnation she was used to, Leela claimed that the War Master was "focus[ed]", "making guesses", and "plotting". In comparison to his past self, the Master claimed he was now "civilised, pleasant, [and] reasonable", which was denied by Leela. (AUDIO: The Devil You Know) He believed that he had "earned" the right to think highly of himself for his actions in the Time War, and looked down on his previous incarnations due to believing they would not be able to handle the conflict. (AUDIO: Masterful)

After his use of the Heavenly Paradigm caused the Dalek Emperor to take control of the Cruciform, the Master, driven by the fear of his failure, fled the end of the universe and used a Chameleon Arch to turn himself into a human baby to hide from the Time Lords and wait out the war in a safe place. (AUDIO: The Heavenly Paradigm)

Under the Chameleon Arch, Professor Yana was a benign old man who had lost faith in the Utopia Project. His spirit was revitalised by the Tenth Doctor, and the two shared a mutual admiration. He was also somewhat scatterbrained and slightly lacking in self-confidence, at one point referring to himself as "a stupid old man." Also, like the Tenth Doctor with Martha Jones, Yana was oblivious to Chantho's feelings for him.

After returning to his true identity, the Master became cold, ruthless, and dignified, but also abusive and condescending, citing that he had the right to attack Chanto when she pointed a gun at him. He was extremely aggressive towards Chantho after regaining his memories, stating that her constant cultural ticks drove him "insane" during their time together. (TV: Utopia)

Though he thought "inappropriate" to have been killed by a female "insect", the Master welcomed his regeneration in a grandiose fashion, declaring that "the Master [was] reborn." (TV: Utopia)

Habits and quirks
When given the chance to rest from the Time War, the Master spent his time cultivating wine. (AUDIO: The Sky Man) He had a great enjoyment of wine, even believing to pit poison in a good enough beverage was "heinous". (AUDIO: Masterful)

Skills
Enjoying "slow-working plans" that gave him ample opportunity to study the small effects that resulted from his ploys, (AUDIO: The Sky Man) the War Master would plan ahead with every scheme, preparing for every eventuality, even his capture. (AUDIO: Sins of the Father) He would also research his targets, and manipulate their history to his benefits. (AUDIO: Concealed Weapon) He likened his plans to wine, as both required "time, patience and discrimination". (AUDIO: Masterful)

He also showed a great capacity for patience in the implementation of his schemes, being willing to wait for prolonged periods of time to find the perfect subject to manipulate, or for the right time to strike. (AUDIO: The Good Master, The Sky Man)

The Master was adept at manipulating individuals quickly in the heat of the moment, (AUDIO: Beneath the Viscoid) using his choice of words and tone of voice to break down their character with his assessment on their quirks and decisions. (AUDIO: Call for the Dead)

Appearance and clothing
In his seventeenth incarnation, (PROSE: Girl Power!) the Master originally looked like an elderly man with white hair and blue eyes. Though he might have started his life clean-shaven, (COMIC: Fast Asleep) he eventually grew a scruffy white goatee beard. (AUDIO: Beneath the Viscoid)

After use of the Chameleon Arch, he regressed into a baby. (AUDIO: The Heavenly Paradigm) When Professor Yana met the Tenth Doctor, he resembled a slightly younger version of his original self, having aged naturally. (TV: Utopia)

He wore a white stiff-collared shirt, often with sleeves rolled up, (AUDIO: Beneath the Viscoid) a crimson waistcoat, a black cravat tie, and black trousers. (TV: Utopia) He once wore a brown tweed jacket over this attire. (AUDIO: The Heavenly Paradigm) During his encounter with UNIT, he wore a velvet trenchcoat. (AUDIO: Master of Worlds) In his waist coat, he housed a Chameleon Arch biodata module, disguised as an ordinary fob watch. (TV: Utopia)

During his expeditionary walks on Arcking, he wore a Grav-Suit over his clothes. (AUDIO: The Good Master)

In a timeline in which he altered the creation of the Daleks, the Master stole the black uniform of a Kaled Military Elite with embroidered white eye logos on the collars. (AUDIO: From the Flames)
