Nyssa

Nyssa — formally Nyssa of Traken or Nyssa, Daughter of Tremas, and on occasion Nyssa Traken — was a native of the planet Traken, the capital of the Traken Union. She was a companion of the Doctor for a brief period towards the end of his fourth incarnation and travelled with him for much of his fifth incarnation. She also travelled with Adric, Tegan Jovanka, and Turlough.

The daughter of Consul Tremas, Nyssa was a child of privilege on Traken. She was gifted with a brilliant intellect and specialised in bioelectronics. When Traken was destroyed, Nyssa became virtually the last of her kind, (TV: Logopolis) and in the wake of the death of her father, the Fifth Doctor once said that he was "pledged to look after her." (AUDIO: Primeval)

She had at least two distinct periods of travelling with the Doctor. She initially travelled with him when she was barely more than a girl, and left his company to help at what was effectively a leper colony on Terminus in the 35th century. (TV: Terminus) She then rejoined the Doctor, Tegan and Turlough in her middle age, after becoming a wife and mother. (AUDIO: Cobwebs)

Encounter with the Fourth Doctor
Nyssa first met the Doctor in his fourth incarnation when he was travelling with Adric. She had recently attended the wedding of her long-widowed father Tremas to Kassia. Unbeknownst to her, had also come to Traken and was planning to exploit the tremendous power of the Keepership (to which her father was the only rightful heir) to live beyond his last natural regeneration. The Doctor and Adric stopped the Master from taking over the Keepership, but could not prevent him killing Nyssa's new stepmother. Unbeknownst to them at the time, the Master also killed Tremas by transferring his essence into Tremas' body, which left Nyssa orphaned in her young adulthood. (TV: The Keeper of Traken)

Soon after, the Watcher took Nyssa to the planet Logopolis. She discovered had, in effect, killed her father. He enslaved her mind, involving her in his complex plan to conquer the universe. The Doctor soon broke her free of the Master's spell, then entered into an uneasy alliance with the Master. The two Time Lords and Tegan Jovanka rushed to Earth in the Master's TARDIS to halt the waves of rampant entropy the Master had unleashed upon the universe. Adric and Nyssa were left with the Doctor's TARDIS on Logopolis. The Watcher helped Adric transport the duo back to Earth. En route, Nyssa witnessed the entire Traken Union being swept away by the growing entropy field which threatened the existence of every part of N-Space. She knew she was the last of her entire species by the time the TARDIS materialised on Earth. When she next met the Doctor, he was mortally wounded in his successful battle to stop the Master. With assistance from the Watcher, he regenerated while Nyssa, Adric, and Tegan looked on. (TV: Logopolis)

Travels with the Fifth Doctor
Because of the Doctor's debilitated state after his fourth regeneration, Nyssa helped him get to the TARDIS before the Pharos Project's security guards could arrest them for trespassing. In the TARDIS, she became even more worried; the Doctor and Adric were lost in the corridors. When she caught up to them, she found he had changed his outfit and was desperately looking for the Zero Room to recover. Moreover, once the Doctor was in the Zero Room, she found the TARDIS had travelled back in time. They were about to be destroyed by Event One, the formation of the galaxy by a massive hydrogen in-rush. Managing to get the Doctor stable long enough to figure out how to escape, Nyssa accidentally jettisoned the Zero Room to give the TARDIS enough thrust to move forward in time. Arriving at Castrovalva, Nyssa found it was a secondary trap by the Master to get rid of the Doctor by using Adric to make block transfer computations. However, they escaped Castrovalva with Adric and the Doctor stabilised. They began travelling; she now no longer had a home to go to except for the TARDIS. (TV: Castrovalva)

Arriving on an Urbankan ship, Nyssa was taken by the android inhabitants to become one of their own, but was rescued by the Doctor and Bigon. Later in the TARDIS, Nyssa fainted from stress. (TV: Four to Doomsday) She could not concentrate; she could not even match Adric at chess. The Doctor made a device called a delta wave augmenter, of which his sonic screwdriver formed an essential part, to let her sleep and recover. Nyssa awoke four days later to discover the Doctor had had an adventure without her. (TV: Kinda) Thereafter, she discovered she had a look-alike by the name of Ann Talbot in England in 1925. The two attended a costume party wearing identical butterfly costumes, making it nearly impossible to tell them apart. George Cranleigh kidnapped Nyssa by mistake, but released her to the Doctor when he discovered his mistake. (TV: Black Orchid)

On one occasion, the Doctor, Nyssa, Adric and Tegan spent Christmas with the renegade Time Lady Iris Wildthyme aboard the TARDIS. (AUDIO: Excelis Dawns)

Nyssa encountered Cybermen trying to attack Earth, but watched as they were foiled by Adric. She was horrified to see Adric give his life to stop the freighter that killed the dinosaurs. (TV: Earthshock) Adric's death was a severe blow to Nyssa and Tegan. While working through their grief, the TARDIS crew was embroiled in an adventure which sent a Concorde back through time. After they had returned the airliner to 1980s Heathrow Airport, the Doctor accidentally left Tegan behind. (TV: Time-Flight)

Nyssa and the Doctor travelled alone together. They visited Alaska, where they stopped revived creatures from Earth's prehistory spreading over the planet and wiping out humanity. (AUDIO: The Land of the Dead) Nyssa began to develop her nascent telepathic powers. (AUDIO: Winter for the Adept, Primeval) She witnessed the birth of the Cybermen on Mondas. (AUDIO: Spare Parts). Nyssa was placed under arrest on Veln, a planet hit by an ecological disaster populated by deformed people. (AUDIO: Creatures of Beauty) She and the Doctor become embroiled in Time Lord politics on an alien world. (AUDIO: Spring) They were arrested for possessing counterfeit coins. (AUDIO: Summer) Nyssa tried her hand at writing a novel. She caught the attention of a local boy called Andrew, fell in love and contemplated life on Earth. (AUDIO: Autumn)

For a short while, Nyssa undertook a solo expedition to 13th century Rhodes, while the Doctor visited 20th century Stockbridge. During that time, she communicated with the Doctor across time and space through a pocket interocitor. Due to the Daleks' manipulation of time and space, she and a knight called Mulberry were transported to the middle of the American Civil War, where she was rescued by the Doctor. (AUDIO: Renaissance of the Daleks)

For a time, she and the Doctor were joined by Thomas Brewster, a human male from Victorian London, specifically 1867. (AUDIO: The Haunting of Thomas Brewster) This threesome had a few adventures — perhaps most notably one in which Nyssa discovered Adric had not died in Earth's prehistoric past — (AUDIO: The Boy That Time Forgot) before Thomas left the TARDIS to pursue a romance in 2008. (AUDIO: A Perfect World)

The Doctor wanted to spend Christmas in Stockbridge with Nyssa, but she didn't want to see to the 21st century, so they ended up in 1899. From there, they travelled to 1199 and Nyssa helped the Doctor to defeat the Rutans. (AUDIO: Castle of Fear)

At some point while she was travelling alone with the Fifth Doctor, they visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963. (AUDIO: The Light at the End)

On one occasion, the Doctor and Nyssa met P. G. Wodehouse. (AUDIO: Autumn)

Nyssa continued travelling alone with the Doctor until they chanced upon Tegan in Amsterdam in January 1983. During the same adventure, she forcefully stood up to the Gallifreyan High Council on the Doctor's behalf. She encountered Omega, who wished to bond with the Doctor to escape the anti-matter universe, but was successful in helping the Doctor prevent this. (TV: Arc of Infinity) Soon after, Nyssa discovered that Tegan was still afflicted by the remnants of the Mara from the Kinda world and helped the Doctor take her to Manussa to permanently destroy the Mara with a "snakedance". (TV: Snakedance) She mistook Mawdryn for the Doctor going through a gruesome regeneration and was infected by his disease. The Doctor nearly gave up his eight remaining lives to cure her and Tegan, but thanks to the unlikely meeting of two Brigadiers, a substitute was found to cure her. At this time, an undercover agent of the Black Guardian, Turlough, began travelling with them to escape exile on earth. (TV: Mawdryn Undead) Nyssa left the TARDIS under circumstances as tragic and noble as those that had forced her into the Doctor's company. The TARDIS attached itself to a space liner when Turlough, under the Black Guardian's influence, damaged its controls. The liner docked with what seemed to be a hulk floating in space, the Terminus space station. The Doctor and Nyssa discovered it was, in effect, a leper colony. She was the only TARDIS crew member who contracted the disease the station existed to treat. Just as she had always done with the tragedies in her life, she used her misfortune as a path to a better future. She chose to remain on the space station to help the Garm and her fellow sufferers find a permanent cure for Lazar's disease. (TV: Terminus)

After her travels
Although she believed she would die — though in her words, "not easily" — on Terminus, (TV: Terminus) Nyssa eventually left and settled down as an academic in a university on another planet. During this period, she encountered the Doctor's fourth incarnation again — long before he had first met her on Traken. (PROSE: Asylum) Eventually, she married and had children, the eldest a daughter, Neeka, with a man named Lasarti, who studied dreams. During this period of her life, she reunited with the Doctor's fifth incarnation and again assisted with his regeneration into his next incarnation. (AUDIO: Winter)

Reunited with the Doctor
Half a century after leaving the Doctor, Nyssa was reunited with him, Tegan and Turlough on the planet Helheim in 3530 while trying to find the cure for Richter's Syndrome, which had claimed over six billion lives. With her own ship destroyed, she asked for a lift home, but resigned herself to more adventures when the Doctor opted to take her by "the scenic route." (AUDIO: Cobwebs) They travelled to Cherdor in the 28th century where they encountered the Takers (AUDIO: The Whispering Forest) and Manussa during the rule of the Manussan Empire where they fought against the Mara. (AUDIO: The Cradle of the Snake)

During these later journeys in the TARDIS, she told Tegan that she was married and had two children, a daughter much like Tegan, and a teenaged son named Adric. (AUDIO: Heroes of Sontar) She also admitted that in her personal timeline she had already experienced the Doctor's problematic regeneration into his sixth incarnation. (AUDIO: Winter) Thus, during this second period of travel with the Doctor, she had to keep her knowledge of the Fifth Doctor's end hidden from him. (AUDIO: Heroes of Sontar, et. al) She was tempted to help intelligent rats create a non-lethal plague in exchange for some tips in fixing the destabilising Helheim cure. (AUDIO: Rat Trap)

During an adventure in India on 31 December 1926, Nyssa was rejuvenated, appearing once again as she had during her early travels with the Doctor. (AUDIO: The Emerald Tiger)

After the TARDIS was pulled off course landed on Valderon, Nyssa learned that 25 years had passed since her mission to Helheim, and that she was presumed dead. She reunited with her son, Adric, who was researching a way to cure Richter's Disease, and learned that her husband had died and her daughter was in suspended animation on another planet, having herself been infected while treating the ill. Adric and Nyssa were able to combine their knowledge to develop a cure. They were to meet in one month's time and revive and cure Neeka, but Adric never saw her again. (AUDIO: Prisoners of Fate) She, along with the rest of the TARDIS crew, went into E-Space where they went to Adric's home planet of Alzarius. (AUDIO: Mistfall) She was interested in in why Isenfel wanted to be in equilibrium. (AUDIO: Equilibrium) She stayed behind in E-Space, where she was dying from Entropy. (AUDIO: The Entropy Plague)

Undated events
At some point, an image of Nyssa was obtained by UNIT and kept in the Black Archive as a record of her having been a companion of the Doctor. (TV: The Day of the Doctor)

Personality
Nyssa seemed at once more mature and more naive than her fellow travellers. She did not boast of her scientific knowledge nor believe it made her superior. She faced her challenges with the determination and serenity of her Trakenite heritage. She turned her sorrow as the last of her people into a desire to help others. Rarely did she mention any grief she suffered because of her great misfortunes. Perhaps most extraordinarily, she never sought to avenge herself on the Master despite her many good reasons to do so.

Tegan noted that Nyssa preferred to "care and share." (PROSE: Goth Opera) Her trusting nature sometimes made her less alert to deception than Tegan (TV: Mawdryn Undead) but it also made her more adept at negotiating an effective balance between strong personalities. (TV: Earthshock, AUDIO: The Game) She had probably the closest relationship with the Fifth Doctor of any of his companions. Nyssa's near-royal upbringing and natural curiosity sometimes made it hard for her to relax and enjoy herself. Though her outlook usually tended to be serious, she displayed a dry wit on occasion, particularly when dealing with the Doctor's boyish idiosyncrasies.

Like all Trakenites, she tended towards pacifism, though on separate occasions she destroyed a Terileptil android in September 1666 (TV: The Visitation), killed a Cyberman in the TARDIS (TV: Earthshock) and used the threat of violence to save the Doctor's life, shooting a pair of guards on Gallifrey. (TV: Arc of Infinity)

She considered Tegan to be her best friend. (AUDIO: The Emerald Tiger). However, she also "never quite understood" why so many of the Doctor's friends were human. (AUDIO: The Boy That Time Forgot)

Nyssa generally didn't use a surname, referring to herself only by the mononym "Nyssa" or, in formal circumstances, "Nyssa of Traken" or "Nyssa, daughter of Tremas." When posing as a human actor, however, she assumed the name "Nyssa Traken." (AUDIO: Special Features)

Behind the scenes

 * Nyssa was originally meant to have appeared only in The Keeper of Traken as a supporting character. She was therefore the sole creation of writer Johnny Byrne, to whom royalties had to be paid when the character was used. Like the Brigadier and K9, she is a rare example of a series regular to whom the BBC does not enjoy sole copyright.
 * Peter Davison was known to have preferred Nyssa over any of his other companions. He intervened on several occasions when John Nathan-Turner attempted to write the character out of the series.
 * Perhaps in deference to Davison's affection for Nyssa, and in part because of Janet Fielding's long reluctance to appear in audio dramas, Big Finish Productions greatly expanded Nyssa's role. They built a network of stories in the televised gap between Tegan's departure in Time-Flight and her return in Arc of Infinity which was very much greater than it had appeared on television. Starting with The Land of the Dead, the Fifth Doctor began a long series of audio adventures with Nyssa as his sole companion. Consequently, Nyssa is one of the most frequently appearing companions in the history of performed Doctor Who stories.
 * Like the Fifth Doctor, Adric and Tegan, Nyssa was given a "costume" rather than a basic "look" by producer John Nathan-Turner. Nyssa's original costume narratively originated on Traken. It suggested her highborn status. It consisted of a maroon velvet jacket, a diaphanous, iridescent skirt, and multi-pastel, high-heeled shoes. It was accessorised with an ornamental hair comb and a woolly purse. This look persisted through the end of part two of Castrovalva. However, long before this episode was filmed, it was determined the actor needed more practical clothing for the physical demands of her now-co-starring role. She exchanged her skirt for a pair of maroon trousers, lost the purse, and began wearing lower-heeled shoes. According to production notes on the DVD release of the preceding story, Logopolis, the second iteration of Nyssa's "royal Traken" look was inspired by a rehearsal in which actress Sarah Sutton wore Nyssa's top, but her own corduroy trousers. She also lost her hair comb. She completely abandoned the "royal Traken" look in Snakedance and changed her look every story thereafter until her departure in Terminus. Famously, her costume for her final story was mostly just the slip she had been wearing under her Mawdryn Undead dress.
 * Images of the older version of Nyssa on cover images for the audio arc in which she rejoined the TARDIS crew were based on contemporary photos of Sarah Sutton.
