Tremas Master

The Master merged with the body of Consul Tremas of the Traken Union This caused his body and clothing to undergo a slight regeneration, making him more youthful, creating a fourteenth incarnation for himself.

In this new body, he continued his crusade to conquer the universe and kill the Doctor. In fact, it was his actions that caused the Fourth Doctor to regenerate. As with his former incarnation, he continued to use disguises in acts of subterfuge. This incarnation of the Master faced the Doctor many times, through several of his incarnations but was always bested.

Origins
About 1981, on the Planet Traken, the centre of the Traken Union, in his crippled and degenerating form, the Master plotted to take over the Source, the power behind the Union, by becoming the new Keeper of Traken. The Fourth Doctor and Adric arrived in response to the Keeper's request and with Tremas' and his daughter Nyssa's help, removed the Master from the Source. Luvic became the new Keeper. With some of the Keeper's powers lingering, the Master was able to merge with Tremas. In his new form, he looked like Tremas, but younger, and with subtle differences. (DW: The Keeper of Traken, Logopolis)

Exploits
The Master travelled 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 carried out on the planet Logopolis and held Logopolis for ransom until its secret was revealed, accidentally causing the causal nexus to unravel and release an unstoppable wave of entropy that would destroy the universe. He also stopped their blockade of entropy, allowing it to swallow several galaxies, including the entire Traken Union.

Tthe entropy wave presented such a threat that he 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, but 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 Doctor's regeneration, the Master kidnapped Adric and held him in a hadron web to make him a part of the Master's TARDIS. Using a projection of Adric on board the TARDIS, the Master sent the Doctor hurling towards Event One to be destroyed, 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. Escaping from the recursion trap and trying to kill the Doctor, he was attacked by the enraged citizens with the city itself due to collapse. (DW: Castrovalava)

The Master escaped from Castrovalva to Earth in 140 million BC, where he disguised himself as the magician Kalid, sparingly using the Xeraphin gestalt as a power source to create Plasmatons. He transported two Concordes to his Citadel via a time contour. The second contained 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, to add to his TARDIS, but then he acquired the Doctor's TARDIS, the Doctor finding him after.

The Xeraphin contacted Nyssa and let Tegan and her enter the Citadel, where he revealed his true form. Holding the passengers to trade 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. The Master traveled to 1215 England where he disguised himself as the French knight Sir Giles and used Kamelion to impersonate John of England to prevent the signing of Magna Carta. The Doctor stopped this plan. (DW: The King's Demons)

Directly following the events in 1215 England, the High Council of the Time Lords discovered that the previous 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 if he complied. 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, thinking it another plot.

He made a temporary alliance with the Cybermen to guide them to the Dark Tower. Brigadier Lethbridge-Stewart knocked him unconscious and Sarah Jane and Tegan 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 death of the old one. 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 had the Merlin come before him to test their truthfulness. When the Master saw the Doctor and Tegan, he told Arthur that he no intention of harming him. He left the court and hurried to his TARDIS, disguised as the turret room of Arthur's castle. The Doctor suggested Arthur create the Knights of the Round so when Mordred came they would be ready. (DWA: The Creation of Camelot)

Developing a more powerful version of the Tissue Compression Eliminator, he accidentally shrank himself. He used Kamelion as his physical proxy in his own shape. He took the Doctor's TARDIS to the planet Sarn, where he commanded Kamelion from a small box. Sarn had nusmaton 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) The Master did not die on Sarn. He went in search the Fountain of Youth to restore himself. (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 escaped and 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.

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. (DW: The Ultimate Foe)


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

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, where he went hunting for human recruits. At the same time, exposure to the planet had caused him to change into a Cheetah Person. He found a pliable young man called Midge and used him to escape.

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

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 caused the Master to be sent back in time thirty-two years 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 assimiliate 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 being 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)



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 lengthy and verbose speeches accompanied by melodramatic gestures and poses. None the less, this incarnation of the Master was dangerous. He was also fanatically and uselessly devoted to killing the Doctor, setting unworkably elaborate traps for him and his TARDIS. His overplanning was his undoing. The Rani said he would get dizzy if he walked in a straight line. 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.

He also tended to adopt disguises and aliases:
