Vislor Turlough

Junior Ensign Commander Vislor Turlough was a companion of the Fifth Doctor. He travelled principally alongside Tegan Jovanka, but also had a few adventures with Nyssa and Kamelion. He briefly met and saved the life of Peri Brown in Lanzarote on 8 May 1984 before leaving the Doctor's company. He also had significant interaction with Brigadier Lethbridge-Stewart, the First Doctor and Susan Foreman. He encountered but did not speak with the Second and Third Doctors and Sarah Jane Smith. After leaving the TARDIS, he also met the Tenth Doctor and Emily Winter.

Turlough was a complex individual. His motivations were often unclear to those around him. He was for a time willingly under the influence of the Black Guardian. During this period, he tried to kill the Doctor. After overcoming the Black Guardian, he was a mostly-trusted member of the TARDIS crew, but there were still moments where his actions were questioned. It was only at the end of his time on the TARDIS that the Doctor finally discovered the truth about how Turlough ended up on Earth and why he was susceptible to the Black Guardian in the first place.

The Doctor once indicated that what made Turlough such an interesting travelling companion was that he never knew what Turlough was thinking.

Early life
Turlough was known in his youth as "Vis". (AUDIO: Kiss of Death)

Turlough rarely talked about his life on Trion before and during the civil war, although his desperation to destroy a distress beacon he recognised as being from Trion and his reluctance to contact his people to save the inhabitants of Sarn indicated there were severe penalties for defiance of his exile. Before the war, Turlough's family was wealthy, and owned a planet. In the military, he held the rank and serial number of "Junior Ensign Commander Vislor Turlough, VTEC9/12/44". In his teenage years, before he became a member of the military, he fell in love with a girl named Deela. Deela's father was on the opposite side during the civil war. His mother was killed during the civil war and his younger brother Malkon and his father were exiled to the abandoned colony planet of Sarn. Turlough himself was exiled to Earth. (TV: Planet of Fire)

Meeting the Doctor
On Earth, he hid his alien origins and lived as a human schoolboy, attending Brendon Public School, where Alistair Gordon Lethbridge-Stewart taught. Turlough was supervised by a custodian masquerading as a solicitor in Chancery Lane. He was contacted by the Black Guardian, who offered him his freedom in exchange for the death of the Fifth Doctor. Turlough ingratiated himself with the Doctor and his companions Nyssa and Tegan Jovanka. He helped resolve a time paradox, after which he was invited to join the Doctor in his travels. (TV: Mawdryn Undead)

During his time at Brendon Public School, he enjoyed studying history. (AUDIO: Phantasmagoria) However, he always hated the works of William Shakespeare. (AUDIO: The Emerald Tiger)

With the Doctor
In subsequent adventures, Turlough received several messages from the Black Guardian, reminding him of his obligation to kill the Doctor — an act he became loath to carry out as he grew fonder of the Time Lord. Finally, he destroyed a prize that would have guaranteed his freedom and his pact with the Black Guardian rather than kill the Doctor, ending his association with the Black Guardian and becoming a loyal member of the Doctor's team. (TV: Enlightenment)

Two days later, Turlough, Tegan and the Doctor arrived on Helheim, where they were reunited with Nyssa (although it had been fifty years for her). (AUDIO: Cobwebs)

The Doctor, Turlough, Tegan and Nyssa then arrived on Cherdor in the 28th century, where they found a society which was obsessed with cleanliness, and lived under the menace of the Takers, for which Turlough was mistaken. After discovering the truth behind the origins of the corrupt society, the TARDIS crew returned to the TARDIS, but discovered that Tegan was still possessed by the Mara. (AUDIO: The Whispering Forest)

They then arrived on Manussa during the Manussan Empire where they fought against the Mara. (AUDIO: The Cradle of the Snake)

While travelling with the Doctor, Nyssa, and Tegan, Turlough reunited with his old love Deela. They had a special place that they'd spent time together and Turlough recalled that they'd last been there together "three years, nine months, and seventeen days" ago. (AUDIO: The Kiss of Death)

After receiving damage from Sentinel Six, the Doctor landed the TARDIS inside Sea Base 4 in the year 2084, at a time where two power blocs were on the brink of nuclear war. When the Doctor and Tegan were trapped in an airlock with the Myrka, Turlough forced Nilson to open the bulkhead door and ensure their safety. He also defended the base from attacking Sea Devils, which three Silurians awoke from hibernation. When the Doctor released hexachromite gas into the base to stop the Silurians and Sea Devils from attacking, he asked Tegan and Turlough to give the Silurians oxygen. When one Silurian reached for its gun, Turlough was forced to shoot it. The Doctor stopped the Silurians from starting a nuclear war between the two human power blocs, but was unable to save any of the humans or reptilian life forms inside the base. (TV: Warriors of the Deep)

Turlough faced the demons of his own people (TV: Frontios) and accepted personal responsibility and trading his freedom for the lives of the population of Sarn. (TV: Planet of Fire)

Although he initially expressed a desire to return to his homeworld and at one point asked the Doctor to take him home, (TV: Enlightenment) after he had spent more time travelling with the Doctor he grew reluctant to return. He destroyed a distress beacon from a Trion ship, attempted to disable Kamelion who he believed was reacting to the beacon and was reluctant to contact his people. (TV: Planet of Fire) After discovering that his younger brother was still alive and the persecution of political prisoners had long been abandoned on Trion, Turlough finally left the TARDIS to return home, after effectively putting the Doctor ("who gets into the most terrible trouble") in the hands of new companion Peri Brown. (TV: Planet of Fire) Later, as he regenerated, the Doctor had visions of several of his past companions, including Turlough. (TV: The Caves of Androzani)

Life after the Doctor
Soon after his return to Trion, Turlough helped save his homeworld and Earth from Rehctaht and the Gardsormr. (PROSE: Turlough and the Earthlink Dilemma)

At one point an enemy of the Doctor's tenth incarnation produced a diary purporting to be Turlough's, though the Doctor had no recollection of Turlough keeping one. (COMIC: Tesseract, COMIC: Don't Step on the Grass) The Doctor and Emily Winter then travelled to Trion, where they met with Turlough to confirm that the diary was not his. (COMIC: Final Sacrifice)

Undated events
At some point, Turlough was taken to the Black Archive by UNIT to have his record as a companion of the Doctor taken. His memories of the visit were subsequently erased and he was sent on his way. (TV: The Day of the Doctor)

Personality
Turlough was selfish, always shielding himself from blame. (TV: Mawdryn Undead) He could lie convincingly to most; some, such as Tegan Jovanka and Brigadier Lethbridge-Stewart, were not fooled. (TV: Mawdryn Undead, Terminus)

Although usually quick to retreat, Turlough was not so much a coward as a survivalist, preferring to avoid danger and situations he felt he couldn't change. (TV: Warriors of the Deep, Resurrection of the Daleks)

Tegan did not like Turlough at first, finding him untrustworthy. She did not approve of the Doctor letting Turlough consider the Black Guardian's offer, believing Turlough would choose the crystal. However, the Doctor was confident in Turlough's morals. Nevertheless, Tegan often tried to persuade him to banish Turlough from the TARDIS. (TV: Terminus, Enlightenment; AUDIO: Cobwebs)

He saved a Phiadoran female to whom he was attracted from a large drop. He appeared to fall in love with Lytalia, but this was later revealed to be a complex deception on the part of the Phiadorans, as the species were currently serving as 'hosts' to the ruthless Vrall and had manipulated men to do their bidding even on their own. Despite this, his experience during this encounter encouraged him to take a closer look at himself and determine who he wanted to be compared to his past actions (PROSE:  Imperial Moon).

Despite the Black Guardian's attempts to vilify the Doctor, he recognised the Doctor's good intentions. On numerous occasions, he tried to make the Black Guardian reconsider his order to kill the Time Lord. (TV: Terminus, Enlightenment) Turlough used the tranquility felt at the Eye of Orion to draw. (TV: The Five Doctors) He understood the TARDIS systems well enough to run a diagnostic (TV: The Five Doctors) and programmed the TARDIS to rescue the Doctor and Peri. (TV: Planet of Fire)

The Doctor once compared Turlough and Tegan to bickering siblings. (AUDIO: Freakshow)

Behind the scenes

 * Turlough was the last male companion to travel with the Doctor on-screen until Adam Mitchell, who joined in the episode Dalek in 2005.
 * Turlough was the last in a seven-year run of non-human televised companions who inhabited the TARDIS, beginning in 1977 with K9 Mark I. Others included K9 Mark II, Romana I, Romana II, Adric, Nyssa and, nominally, Kamelion.
 * When he was introduced in 1983, Turlough became the first companion since Jo Grant not to have travelled with the Fourth Doctor.
 * Mark Strickson himself did not have red hair. He dyed his hair for the role, as his natural fair hair was seen by John Nathan-Turner as too similar to Peter Davison's Fifth Doctor hairstyle.
 * Turlough's serial number, VTEC9/12/44, was derived from the date of birth of Eric Saward.
 * Turlough was dubbed in German by voice actor Jan Koester.
