Tremas Master

The Master merged with the body of Tremas of the Traken Union as his thirteenth and heavily decayed body could not hold out. The merger made him look like a younger Treams, but this merger was not without any draw-backs; because he was not a pure Time Lord any more, he no longer had the ability to regenerate, meaning he would need to seek another body once this one began to fail him. In this fourteenth incarnation, he continued his crusade to conquer the universe and destroy the Doctor.

As did his former incarnation, he used fairly good disguises in acts of subterfuge. This incarnation of the Master faced the Doctor's fourth, fifth, sixth and seventh incarnations but was always bested; he faced the Fifth Doctor more than his successors, oddly only making fewer appearances to the future incarnations of his old foe. This did not stop him from constantly trying to kill the Doctor with overplanned schemes.

He temporarily teamed up with a fellow evil Time Lord, the Rani, as part of his own schemes to get rid of the Doctor and to conquer the universe; it backfired, leaving them in one of the Doctor's traps. During the Sixth Doctor's trial, he assisted him by sending witnesses to prove the Valeyard's evidence had been tampered with; the Valeyard was a version of the Doctor he saw could not be beat, meaning he was better off with the original.



Origins
About 1981, the Master plotted to take over the Source on the Planet Traken, the power behind the Traken Union. He wished to be the new Keeper of Traken, but ended up trapped in his TARDIS upon arrival on the plant; his evil permeated the Melkur statue whose form his TARDIS toke. Once the current Keeper's power waned, the Master managed to take the Keeper's power for himself. As an unexpected bonus to his plans, the Master found the Doctor was summoned by the Keeper; with the power of the Source, the Master would be able to merge with the Doctor to get a new body. With the help of Tremas and his daughter Nyssa, the Doctor removed the Master from the Source. With some of the Keeper's powers lingering, the Master merged with Tremas. In his new form, he looked like a younger Tremas. (DW: The Keeper of Traken, Logopolis)

However, because Tremas' body was not that of a Time Lord, it could not regenerate but would age instead. The Master would have to steal another body to survive.

Exploits
The Master went to Earth, where he trapped the Doctor's TARDIS in a gravity bubble. He killed Tegan 's aunt Vanessa and a police constable with his Tissue Compression Eliminator. He perverted the Block Transfer Computations performed on Logopolis and held the planet for ransom until its secret was revealed. This made the causal nexus unravel and release an unstoppable wave of entropy to destroy the universe. He also broke the the Logopolitans' blockade of entropy, allowing it to swallow several galaxies, including the entire Traken Union.

The entropy wave was so threatening that the Master agreed to work with the Doctor to stop it. They travelled to the Pharos Project on Earth to do so. His true plan was revealed however, when he sent a message to the peoples of the universe that he would stop the entropy only if they submitted to his rule. While stopping the Master's signal to shut down the CVE that would halt the entropy wave, the Doctor fell off the Pharos Project's radio telescope and regenerated, allowing the Master to escape. (DW: Logopolis)

After the Fifth Doctor's regeneration, the Master kidnapped Adric and held him in a hadron web to make him a part of his TARDIS. Using a projection of Adric on board the TARDIS, the Master sent the Doctor hurtling to destruction at Event One, but the Doctor saved the TARDIS through the Architectural Configuration. The Master used Adric's block transfer computations to create Castrovalva in the Andromeda Galaxy, where the Doctor would recover from his regeneration. He escaped from the recursion trap and tried to kill the Doctor, but was attacked by the enraged citizens with the city itself due to collapse. (DW: Castrovalava)

The Master escaped from Castrovalva, however, in the attempt, it caused damage to the dynamorphic generators, making it difficult to continue piloting the TARDIS. (PDA: The Quantum Archangel) So he travelled to Earth in 140,000,000 BC, where he disguised himself as the magician Kalid, hoping to use the Xeraphin gestalt to replace his dynamorphic generators. Therefore, he brought two Concordes to his Citadel via a time contour. The second held the Doctor, his TARDIS and companions. He originally planned to use the captured passengers to break into the Sanctum and take control of the Xeraphin and add him to his TARDIS, but then he acquired the Doctor's TARDIS, with the Doctor in pursuit.

The Xeraphin contacted Nyssa and let Tegan and her enter the Citadel, where he revealed his true form. The Master held the passengers hostage for parts from the Doctor's TARDIS. The second Concorde was returned to its own time and the Master ended up on Xeriphas with the freed and angry Xeraphin. (DW: Time-Flight)

There, he found Kamelion, a shape-changing android. He escaped to 1215, England. He disguised himself as the French knight Sir Giles and made Kamelion impersonate John of England to prevent the signing of Magna Carta. The Doctor stopped this plan. (DW: The King's Demons)

Directly following these events, the High Council of the Time Lords discovered that earlier incarnations of the Doctor had been taken into the Death Zone on Gallifrey. They asked the Master for help and offered him a new cycle of regenerations. He agreed and was given a copy of the Seal of the High Council by the Castellan. The Doctor's third incarnation did not believe him.

He made a temporary alliance with the Cybermen to guide them to the Dark Tower. Brigadier Lethbridge-Stewart knocked him unconscious and Sarah Jane Smith and Tegan Jovanka bound him. After the Castellan was encased in Rassilon's tomb, Rassilon sent the Master back to his own time. (DW: The Five Doctors)

The Master arrived in Camelot just after the coronation of King Arthur. He became the Merlin after the old one had died. He planned to make Arthur believe Mordred was dead so Mordred would grow up to kill Arthur at the battle of Camlan.

The Doctor and Tegan arrived, met Arthur and told him about the Master. Arthur summoned the Merlin to test their truthfulness. When the Master saw the Doctor and Tegan, he told Arthur he had no intention of harming him. He left the court and hurried to his TARDIS, which was disguised as the turret room of Arthur's castle. The Doctor suggested Arthur create the Knights of the Round Table so when Mordred came they would be ready. (DWAN: The Creation of Camelot) The Master developed a more powerful version of the Tissue Compression Eliminator and accidentally shrank himself. He used Kamelion in his own shape as his physical proxy. He took the Fifth Doctor's TARDIS to the planet Sarn, where he commanded Kamelion from a small box. Sarn had Numismaton Gas, which he hoped could restore him. As the Master stood in a gas vent, the Doctor used the gas to burn him (apparently) to death. (DW: Planet of Fire) However, the Numismaton Gas increased the power of the Source of Traken still remaining in the Master body. (PDA: The Quantum Archangel) The Master did not die on Sarn. He went in search the Fountain of Youth to restore himself, which he managed to exploit. (ST: A Town Called Eternity)

The Master allied with the Rani (whom he knew as a member of the Deca on Gallifrey) in Killingworth, an early 19th century English mining village, against the Sixth Doctor and Peri Brown. The Doctor trapped the Master and the Rani in her TARDIS, which the Doctor had sabotaged. (DW: The Mark of the Rani) The Master separated the Rani's console room from the rest of her TARDIS, leaving her to drift aimlessly through the vortex. (MA: State of Change)

Now in the Matrix, the Master observed the Sixth Doctor's trial on Space Station Zenobia. He considered the Valeyard a rival and rescued the Doctor rather than have the Valeyard win. He used Sabalom Glitz, always ready to work with anyone for a quick grotzit, as a tool. He tried to steal secrets from the Matrix, but he was double-crossed, and imprisoned in the Matrix with a limbo atrophier. (DW: The Ultimate Foe)


 * After escaping from the Matrix, the Master could regenerate his body because The Source of Traken still existed within him. (PDA: The Quantum Archangel)''

After escaping from an unsuccessful alliance with the Krotons, the Master discovers that the last remnants of The Source of Traken are fading, so his previous cadaverous form will return and he will die. Meanwhile, he is attacked by the Chronovores, looking for revenge after he tortured Kronos. So the Master devises a plan to destroy the Chronovores and achieve omnipotence, by trying to access the Lux Aeterna using the son of TOMTIT, the TITAN Array. He steals the equipment, but uses it upon a woman he has hypnotised, Anjeliqua Whitefriar, expecting it to destroy her before he uses it. However, she absorbs the Lux Aeterna, achieves omnipotence and becomes the Quantum Archangel. Using her power, she fills the universe with too many alternate timelines, leading the Chronovores to feast upon them, eventually leading to the end of the Universe. So the Master (fully returned to his cadaverous form again) and the Doctor team up to rectify the Master's mistake, by defeating the Quantum Archangel. They discovered that the Quantum Archangel has allied itself with the Mad Mind of Bophemeral so it can have infinite knowledge of the Universe. Furthermore, the Doctor and the Master encounter Kronos, who claimed to have been the one who attacked the Master's TARDIS, so he would come up with his plan, and would eventually lead to the Master destruction. As well as allowing Anjeliqua to survive, causing Kronos plan for revenge to go wrong. But they succeeded by draining the Lux Aeterna out of her. Although, not before the Master escaped using the TITAN equipment to harness the Lux Aeterna to restore his Tremas body. (PDA: The Quantum Archangel)

After trying to start a war between Antari Two and Antari Three, (NA: First Frontier) the Master went to the Cheetah World, where he took control of the Cheetah People and the kitlings. He sent them to Ace's home in the London suburb of Perivale and hunted for human recruits. At the same time, exposure to the planet had changed him into a Cheetah Person. He found a pliable young man called Midge and used him to escape.

The Seventh Doctor and Ace found him. The Master killed Midge and teleported the Doctor to the Cheetah World, which had begun to break up. The Doctor escaped but the Master was trapped on the dying world. (DW: Survival)

Fate
One account told of the Master escaping the Cheetah planet with the aid of a Kitling just as the planet exploded. The explosion of the planet sent the Master back in time to Earth in 1957.

On Earth, the Master interrupted the real first Soviet satellite launch and sent a distress signal to the Tzun Canton on Zeta Reticuli Four. He offered to help assimilate Earth into the Tzun Confederacy. In return the Master asked for passage off Earth and the use of the Tzun's genetic engineering to cure his Cheetah Virus infection. The Tzun agreed and gave the Master a new body. (NA: First Frontier)

However, other accounts told of the Master escaping the Cheetah World still infected by the Cheetah Virus. On Earth, he tried to cure the virus by extracting nutrients from dying humans. (ST: Stop the Pigeon) The Master next tried to gain a new body from legendary aliens, the Fleshsmiths. The Master's plan was stopped by the Doctor, who ejected the new body from the Fleshsmith vessel into space. (PDA: Prime Time)

A third account suggests that later in his life, the Master captured seven of the Doctor's incarnations and put them into a void called the Determinant. The Graak freed the Doctor and the Master was put on trial. (VG: Destiny of the Doctors) It was suggested that those who put him on trial were the Daleks. This account would lead directly into the Master's trial on Skaro. (DW: Doctor Who, EDA: The Eight Doctors)



Personality
This incarnation of the Master was charismatic, deadly and sophisticated but decidedly more flamboyantly evil, bombastic and futile than his predecessors. He was prone to laughing maniacally and reciting verbose speeches accompanied by melodramatic gestures and poses. Even so, this incarnation was dangerous. He was also fanatically and uselessly devoted to killing the Doctor, setting overly elaborate traps for him and his TARDIS. The Rani said he would get dizzy if he walked in a straight line. His over-planning was his undoing.

He was tall and thin with black hair and a goatee beard. This incarnation of the Master had a particular fondness for the Tissue Compression Eliminator.

Aliases
He also liked to adopt disguises and aliases:


 * The Portreeve (DW: Castrovalva)
 * Kalid (DW: Time-Flight)
 * Sir Gilles Estram (DW: The King's Demons)
 * The Merlin (DWAN: The Creation of Camelot)
 * A scarecrow (DW: The Mark of the Rani)
 * The Sheriff (ST: A Town Called Eternity)


 * For more details, see Aliases of the Master.

Other information

 * A hallucination of this incarnation of the Master appeared to the Doctor as he lay dying of spectrox toxaemia in the TARDIS. (DW: The Caves of Androzani) This was due to the Master's attempts to psychically interfere with the Doctor's fourth regeneration. (BFA: Winter)
