Peri Brown

Perpugilliam Brown, also known as Peri, was a companion of the Fifth and Sixth Doctors, as well as a temporary companion to the Second Doctor during an encounter with Dastari.

She was an American college student who accidentally joined the Fifth Doctor during his visit to Lanzarote in 1984. She then elected to remain with him for the rest of her vacation time. She remained with the Doctor after his regeneration into his sixth incarnation, but found it harder to get along with him because of his now brash and arrogant personality. However, as time went on, the Sixth Doctor's personality mellowed and Peri's friendship with him improved, especially after he returned to comfort her after the death of her mother.

Peri was separated from him by the Time Lords so that they could cover up the Ravolox conspiracy. According to, Peri fell in love with King Yrcanos and married him, but that was just part of the truth. As it turned out, there were several future versions of Peri's life due to interventions of various Time Lord factions. At least one of these versions of Peri eventually rejoined the Sixth Doctor on his travels after Yrcanos died, though she returned to Krontep once a year to pay tribute to her late husband.

Peri had limited contact with other companions, although she did encounter a few. She spent a significant amount of time alongside the uncrowned Egyptian Pharaoh Erimem, developing a deep sister-like bond. As well as this she had a series of adventures with Frobisher. She was also acquainted with Jamie McCrimmon, meeting him and the Second Doctor during an encounter with the Sontarans. She also very briefly met Vislor Turlough who left the Doctor's company just prior to her joining. She also met Kamelion briefly before his destruction. She also briefly met Ace, accompanied by the Seventh Doctor, at the Factory.

Childhood
Perpugilliam Brown was born in 1966 as the only child of archaeologists (PROSE: Blue Box) Paul and Janine Brown, who had married on 21 November 1962. She had an aunt named Mona who lived in a trailer park. (AUDIO: Peri and the Piscon Paradox) Perpugilliam was an old family name (PROSE: Players) which she claimed meant "she who lives in the hills" (AUDIO: The Bride of Peladon) or "by a handful" (PROSE: A Handful of Stardust) and which she often found people had difficulty pronouncing. (PROSE: Revelation of the Daleks)

According to most accounts, Peri was raised in Baltimore, (PROSE: House, The Ruins of Heaven; AUDIO: The Reaping; TV: ) specifically Fell's Point, (AUDIO: The Reaping; TV: ) where she enjoyed a stable life and was best friends with Kathy Chambers, whose brother Nate she fancied. (AUDIO: The Reaping) According to other accounts, she came from New York City, (PROSE: The Twin Dilemma, Revelation of the Daleks) Pasadena (PROSE: Synthespians™, Something Borrowed) or New England, (PROSE: The Mark of the Rani) specifically Boston. (PROSE: The More Things Change)

Peri was raised as a Baptist (AUDIO: The Council of Nicaea) and made to attend church every week, (PROSE: The Ruins of Heaven) but she would later consider herself not to be religious. (AUDIO: The Council of Nicaea) She travelled the world with her parents due to their careers (PROSE: Blue Box) and she enjoyed a comfortable life thanks to their wealth, but she was only truly happy amongst nature and was fascinated with botany. (PROSE: Synthespians™)

Janine once took Peri to the Boston Botanical Centre when she was eleven (PROSE: Superior Beings) and she once visited Kew Gardens and Wembley Stadium where she saw AC/DC and the Who, (PROSE: The Church of Football) although she would later tell the Sixth Doctor that she had never visited London. (TV: Attack of the Cybermen) She also visited Bath Abbey (PROSE: Superior Beings) and Las Vegas. (PROSE: Something Borrowed)

As a girl, Peri read the comic book Swamp Thing (PROSE: Players) and read about the Philadelphia Experiment. (AUDIO: The Macros) Her father took her out hunting and they had a dog called Whiskey. (AUDIO: Peri and the Piscon Paradox) She had the opportunity to take horse-riding lessons, but chose not to. (AUDIO: The Church and the Crown)

Teenage years
Paul taught Peri how to use a gun, although she did not like handling them (PROSE: Attack of the Cybermen) and was not confident in her ability to use them. (TV: Attack of the Cybermen) When she was thirteen, her father died in a boating accident. (PROSE: Synthespians™) Janine married Professor Howard Foster, another archaeologist, who already had two children. (PROSE: Shell Shock) According to some accounts, Howard sexually abused Peri, although accounts differed on whether Janine was unaware of this (PROSE: Synthespians™) or whether she never forgave him. (PROSE: Shell Shock)

In high school, Peri was a "straight A" student. She studied Christopher Columbus, whose actions she was disgusted by, in great detail (AUDIO: Trouble in Paradise) and learnt British history, covering Henry VIII. (AUDIO: Recorded Time) She was top of her class in botany and dreamed about discovering a new plant species or having a flower named after her. (AUDIO: Paradise 5) Whilst living in Baltimore, Peri would sometimes go to the graveyard and read inscriptions upon the tombstones. (AUDIO: Emissary of the Daleks)

Peri's first boyfriend was George Stewart, whom she nicknamed "Curious George" and who crashed the car on their way to their first date because he was distracted by her legs. (AUDIO: Peri and the Piscon Paradox) When she was sixteen, she was dumped by "a real creep" and was upset until her grandmother called her and told her to pull herself together. She started dating Davey Silverman, who never left her alone for the first three months of their relationship and was nervous when she once used the subway, something that she interpreted as him being overprotective. (AUDIO: Peri and the Piscon Paradox)

In her gap year, Peri read À la recherche du temps perdu and believed that Marcel Proust could have benefitted from a better editor. At some point, she also read Black Orchid. (AUDIO: Year of the Pig)

College
Peri began studying Botany (TV: The Mysterious Planet) at college (TV: Planet of Fire) in 1983 (AUDIO: The Mind's Eye, Peri and the Piscon Paradox) whilst maintaining an interest in archaeology thanks to her parents and Howard. (PROSE: Blue Box) Accounts differed on whether she attended Boston University, (PROSE: Burning Heart) Berkeley (PROSE: Synthespians™) or California State. (AUDIO: Peri and the Piscon Paradox)

Peri considered breaking up with Davey rather than have a long-distance relationship whilst she was at college and he punched a door when he realised this was the case. She ultimately decided to stay with him, (AUDIO: Peri and the Piscon Paradox) although she did date Chuck for a time and found that he was unable to give simple answers to any question, always speaking in "jargonese". (PROSE: Attack of the Cybermen) She would later remark that she had to deal with a number of "dumb jocks" in college. (PROSE: Superior Beings)

On campus, Peri was a sports star, enjoying playing tennis, hockey and lacrosse. (PROSE: The Two Doctors) Whenever she passed the Zoology laboratory on campus, she was glad that she chose to study Botany instead as she did not know what was going on with the animals inside. (AUDIO: Year of the Pig) She shared a residence with other girls, (AUDIO: Peri and the Piscon Paradox) was friends with Sara (PROSE: Burning Heart) and knew a girl with an eating disorder who was referred to a counsellor. (AUDIO: Year of the Pig)

First meeting
On a vacation to Lanzarote on 9 May 1984, (AUDIO: The Reaping) Peri met three Englishmen and decided to go with them to Morocco before returning to college in the autumn, cashing in her return ticket to New York. However, Howard stopped her from making it to the airport on time by stranding her on a boat.

Peri was saved by Vislor Turlough from drowning and was taken by him into the TARDIS where she met the Fifth Doctor and Kamelion, who assumed Howard's form and, later, 's. Kamelion seized control of the TARDIS and took Peri to Sarn where she met the real Master. Following his defeat and Turlough's return to Trion with his brother, Peri joined the Doctor on his travels with the intention of returning to finish her degree. (TV: Planet of Fire)

Early adventures
When the Doctor received a summons and materialised the TARDIS in 12th century England, he decided that it was not the right place for Peri's adventures in time and space begin and told her to wait inside whilst he answered the call. (PROSE: Five Card Draw)

On N'Tia, Peri began to regret joining the Doctor but decided that she had made the right choice upon seeing the planet's beauty. (PROSE: Light at the End of the Tunnel)

To recover from her experiences with the N'Tians, the Doctor took her shopping in London where they watched Les Misérables. (PROSE: Black and White)

The Doctor took Peri to Astroville Seven in the 31st century to help her acclimatise to being amongst various species of aliens and, wanting to choose clothes for herself rather than be limited to what was in the TARDIS wardrobe, she went shopping. They became caught up in a quest for the legendary treasure of Rovan Cartovall. (PROSE: The Ultimate Treasure)

On Earth, she watched Len Skeggs die after stealing the Eye of Gaar. (PROSE: Hot Ice)

On Mars in the 2000s, Peri and the Doctor encountered the Ice Warriors and met the crew of the Argosy. When the Argosy crash-landed, Peri went with Paul and Tanya Webster to Izdaal's tomb. (AUDIO: Red Dawn)

A week into her adventures, she once again met the Master, this time in 1880s California. (PROSE: A Town Called Eternity)

A week later, the Doctor took her to watch a football game and she encountered Edward Grainger (PROSE: The Church of Football) before going to 2099 Prague. (PROSE: Leap Second)

She later met the Valethske and narrowly avoided becoming a meal. Despite understanding how she felt, the Doctor disapproved of the visceral hatred she developed for Veek's people. (PROSE: Superior Beings)

With Erimem
After travelling alone with the Doctor, they met Erimem, a princess of ancient Egypt, who joined them in the TARDIS. (AUDIO: The Eye of the Scorpion)

The Doctor intended to drop Erimem off on the Braxiatel Collection so that she could have an education. Instead, they arrived in 17th century Paris. There, Peri was kidnapped by the Duke of Buckingham, who believed that she was Queen Anne (a look-alike of Peri). After this adventure, the Doctor invited Erimem to join them travelling in the TARDIS. (AUDIO: The Church and the Crown)

By this time, Peri had found one of Leela's skins in the TARDIS wardrobe and considered wearing it on one occasion. (AUDIO: No Place Like Home)

Peri grew exceptionally close to Erimem and hoped her feelings for Erimem were like those she had for a sister. (PROSE: Blood and Hope) She helped teach Erimem to read English.

The three battled Jarra To in the Axis, (AUDIO: The Axis of Insanity) defeated the Great Old Ones in the Himalayas (AUDIO: The Roof of the World) and prevented the Khellians from preying on a vulnerable Earth colony. (AUDIO: Three's a Crowd)

The trio next visited Nicaea in 325 AD, where they found themselves in the middle of a religious conflict. (AUDIO: The Council of Nicaea)

Peri and Erimem were stranded in 15th century Earth when the TARDIS separated them from the Doctor, having to work as serving wenches. They were eventually reunited with the Doctor after coming into conflict with William Shakespeare. (AUDIO: The Kingmaker)

As part of a scheme with his seventh incarnation, the Doctor left Peri and Erimem in Monte Carlo in 1966 to stop the theft of the Veiled Leopard at a party. They discovered the thief was Lillian Hawthorne and stopped her getting away, returning the jewel to its safe. (AUDIO: The Veiled Leopard)

Later, Peri and Erimen corrected a change to the timeline caused by the Doctor's former companion Tegan Jovanka. The three women proceeded to go out and get drunk afterwards. (PROSE: Graham Dilley Saves the World)

In a hallucination induced by the plants of YT45, Kyropite, she believed that she had a boyfriend with a stepson, Kyle. She had to deal with Kyle's unruly behaviour. She was eventually found being ingested by the plants. Inside the dream her stepson caught Meningitis, this corresponded to her health deteriorating in the real world. As it got worse she imagined her partner cheating on her and then she was run over by a car. Takol wanted her to die for his experiment. She didn't recognise the Doctor when he went into her dream. As her dream became a bad drama, the Doctor asked her to choose. As she awoke the plant removed itself from her. Both Erimem and the Doctor took her back to the TARDIS to escape. (AUDIO: The Mind's Eye)

The Doctor, Peri and Erimem visited Peladon after answering a distress call from the Ice Warrior prince and ambassador Zixlyr in the 41st century. King Pelleas proposed to Erimem, and she accepted, parting with Peri and the Doctor to stay to rule Peladon. The Doctor and Peri departed for the TARDIS, still in orbit around Peladon with the help of Alpha Centauri's ship. (AUDIO: The Bride of Peladon)

Later adventures
Soon after Erimem's departure, Peri and the Doctor went to the planet Grallista Social for a spot of relaxation but found themselves in the midst of a viral decontamination effort by the Viyrans. She was infected with a virus which turned anyone she came into contact with. The Viyrans were getting her to remember each time this happened, first with the Doctor, then with Chris and finally Lawrence as a way to remove her memories as part of the cure. Her memory wouldn't be erased as easily so the Viyran wanted to kill her. She realised that her memory was returning as her memory was trying to work out what had happened and why it was happening. (AUDIO: Mission of the Viyrans)

Peri and the Doctor went to the village of Sair during the Middle Ages, where a young man named Tablibik used a form of magic to make her fall in love with him. The Doctor swiftly broke his spell. (PROSE: Fascination)

After Peri was badly injured, the Doctor took her to Karn where she was kidnapped by Morbius. However, she was able to trick him into putting her into an escape pod and escaped to Sylvana where she became a guerrilla leader against his regime. She eventually rejoined the Doctor after he became the general of an army of Draconians, Sontarans, Cybermen and Ice Warriors against Morbius. (PROSE: Warmonger)

Peri was intentionally separated from the Doctor on an unnamed world. During this separation, the Doctor travelled briefly with a tracer named Amy whom he helped find the Key to Time. Peri was reunited with the Doctor after his second attempt at finding the Key to Time concluded. (AUDIO: The Judgement of Isskar, The Chaos Pool)

The two met an Essex priest who was hiding alien bodies in his church crypt in 1953. (PROSE: The Canvey Angels)

Peri was, for a time, separated from the Doctor on a World War I battlefield in 1914. (PROSE: Never Seen Cairo)

The two met Alistair Gordon Lethbridge-Stewart before encountering the Arix. (PROSE: A Life in the Day)

Peri helped the Doctor save a group of human colonists beset by the carnivorous Farakosh. (AUDIO: Exotron)

Peri pretended to be a waitress in an alien restaurant to figure out why three different gourmets wanted to kill the Doctor. (AUDIO: Urban Myths)

Peri helped the Doctor stop the Valtor from invading Beadledom 3. (AUDIO: Rulebook)

Arriving in Los Angeles in 2009 to stop Zarl from selling Earth's water to his fellow Piscons, Peri met a future version of herself who, unbeknownst to her, only remembered her first adventure with the Doctor. She was disgusted by her future self when she apparently killed Zarl and Carburetor and greatly upset upon learning that her future self had lied about having children, which she wanted more than anything. She decided that she would stay with Davey Silverman when her travels came to an end and wondered about how her relationship with the Doctor, who decided to take her to Androzani Minor, would change given what he had seen her future self do. (AUDIO: Peri and the Piscon Paradox)

Whilst exploring Androzani Minor, Peri and the Doctor contracted spectrox toxaemia and became caught in the conflict over spectrox between Androzani Major government forces and Sharaz Jek's insurgency. They were arrested by government forces and sentenced to execution, but they were abducted by Jek, who was attracted to Peri. They escaped with the aid of fellow prisoner Salateen, however the Doctor became separated from them. Salateen took her back to the soldiers, however she was abducted by Jek again. She began to die from the disease and the Doctor gave her the single dose of bat's milk he was able to acquire before regenerating into a new incarnation, to her astonishment. (TV: The Caves of Androzani)

The new Doctor
Peri was disturbed by the Sixth Doctor's behaviour following his regeneration and terrified after he attempted to strangle her, leading him to decide to repent for his actions as a hermit on Titan III before they found the wounded Hugo Lang and learnt of the kidnapping of Romulus and Remus Sylvest. Joined by Hugo, they followed Azmael and the Sylvests to Jaconda where they were captured by Mestor, whom the Doctor and Azmael killed. Peri tried to get the Doctor to stay to help the Jacondans and admonished him for being rude to Hugo when they parted, but he asked her to get to wait before condemning his new persona. (TV: The Twin Dilemma)

Peri wanted to return home, but decided to acquiesce to the Doctor's request and get to know him. (PROSE: The Twin Dilemma) He called Peri by the names of various former companions of his, as well as Zodin, in the days following Jaconda (TV: Attack of the Cybermen) and, according to one account, they spent a week frozen inside of a glacier on Vespod Eight. Otherwise, Peri spent her time studying in case she returned to college and demanded that she and the Doctor discuss terms for her remaining on the TARDIS. (PROSE: Attack of the Cybermen)

After picking up Gustave Lytton's distress call in 1985, Peri and the Doctor descended into London's sewers and encountered Cybermen who infiltrated the TARDIS and forced the Doctor to take them, Lytton and Charles Griffiths to Telos. There, Peri was saved from a deranged Cyberman by Rost and Varne, from whom she learnt of the Cybermen's plan to destroy Earth and who wanted her to destroy the TARDIS to prevent this, and was eventually reunited with the Doctor. She told the Doctor that Lytton was working with the Cryons, but they were too late to save him and they left Telos before Cyber-Control was destroyed. (TV: Attack of the Cybermen)

The Doctor kept making attempts to repair the TARDIS's chameleon circuit, causing it to switch between various shapes before returning to the form of a police box. It was then that Peri demanded that he stop. (COMIC: Quick Change) He had a number of accidents in the TARDIS, including burning dinner despite promising a cold supper, (TV: Vengeance on Varos) and Peri thought more and more about returning to college. (PROSE: Vengeance on Varos)

When the TARDIS's trans-power system failed, Peri and the Doctor travelled to 23rd century Varos on emergency power to acquire Zeiton-7 and saved Jondar from execution in the Punishment Dome, only for Peri to be captured and taken to the Governor, the Chief Officer and Sil. She was accused of being a spy for Amorb and taken by Quillam for his cell mutation experiments, which began turning her into a bird hybrid, but the Doctor saved her and, after being recaptured and escaping with the Governor and Maldak, Sil was defeated. With a supply of Zeiton-7, Peri and the Doctor left to continue their travels. (TV: Vengeance on Varos)

Peri stayed in her bedroom reading Jeffrey Archer after leaving Varos because she was tired of being shouted at, but the Doctor barged in after detecting something following them through the Time Vortex. She realised that the object was sending signals which they followed to the Overseers, whom they learnt had been interfering with reality to make the Doctor's adventures more interesting for them to sell as entertainment. The Doctor was ultimately powerless to stop them from doing so. (PROSE: Telling Tales)

Whilst scuba-diving, Peri became separated from the Doctor and was found by the Memory, which fed on her sense of self as well as her body and which she refused to give into. She accessed its mind and used it to create a woman whom she sent to find the Doctor, but she had been reduced to a disembodied brain by the time he found her and he had to use his connection to the Memory to put her mind back together and create a duplicate body. Her new body was exactly the same as her original, although it was initially hairless. (PROSE: Shell Shock)

Running in the new Zeiton-7 landed the Doctor and Peri in Dorsill where Peri saw Edward Baddesley dig up Bill Neville's corpse, which he demonstrated when confronted by the Doctor was to inspect it as there had not been a post-mortem. The corpse came to life before they could return it to its grave and the Doctor and Edward went after it whilst Peri waited in the pub because of a cold, learning from Janet Spillsbury that Christopher Sheldon had been working on a DNA computer. Realising that alien DNA had been used as part of an MoD experiment, the Doctor ensured that everybody got the antidote, including Peri after she was infected. (PROSE: Grave Matter)

The Doctor took Peri to Earth tens of thousands of years into her future to acquire a six-dimensional anomaly to recalibrate the TARDIS and repair some of the damage he had done to it. Peri was caught by Monitors looking for Kimo Ani after picking up the Wibliwee's ship and put in suspended animation with the rest of humanity, but the Doctor and Kimo Ani saved her. After the Doctor used the Wibliwee's ship to repair part of the TARDIS, Peri checked that the kitchens were in working order once again. (PROSE: Moon Graffiti)

Before the TARDIS materialised on Reef Station One, Peri's mind was touched by the Nestene Consciousness and she had a vision of Shub-Niggurath sending her children out to colonise the universe. She befriended Claudia Bruderbakker and helped investigate after her father was killed by her step-mother, keeping Walter J. Matheson busy as the Doctor and Claudia looked into Skin Deep and discovered the involvement of the Autons. Matheson subjected Peri and Claudia to the Skin Deep process, but the Doctor saved them and, after the Nestenes' defeat, Peri declined Claudia's offer to give up her life of adventure and stay with her and Marcus Brooks, whom she considered a "ready-made" boyfriend, in the 101st century. (PROSE: Synthespians™)

Peri asked the Doctor to take her to Rome to see the Colosseum where they noticed a gladiator carrying a digital watch, leading them to follow chronon energy radiation through time and to find various other anachronisms. After six days, they arrived at Dotty's in New York City where they met the amnesiac Jacob, whom they learnt had been travelling through time on a gap year using a BackPack and had saved the life of Dorothy in 1897, changing his own timeline and causing him to start fading out of existence. He chose to let himself disappear than stop himself saving Dorothy, but Peri was delighted to learn from Mary that Dorothy had never forgotten him. (AUDIO: Not Forgotten)

Peri was considering leaving the TARDIS because of how emotionally inaccessible the Doctor had been since his regeneration when they landed on Eldair and found House killing the sole survivors of a nuclear war. She and the Doctor tried and failed to convince Carl and Roger to leave with them, forcing them to leave them behind. Afterwards, the Doctor told Peri that her bedroom had once belonged to Susan Foreman and, reflecting on his words on home, she decided to stay and thanked him for the room. (PROSE: House)

Whilst looking through the Doctor's pockets for a pen, Peri found a note he had written to remind himself to remove the body of a vampire-like creature from a Holiday Opportunity Promotions timeshare in North Devon in 1920 and shut it down. He ignored Peri's reading of the coordinates, so they instead arrived in 1929 and caused a potential temporal disaster by putting money in the timeshare meter when Godfrey and Camilla Richardson had already done so. After a Time Lord explained the Doctor's note to him, he went back to remove the body and he and Peri used up two weeks' time in the course of a week to resolve the temporal issues. (PROSE: Timeshare)

Peri left the TARDIS in a rush after having an argument with the Doctor and was admonished by the natives and the voice of the Monitor for how revealing her shorts and top were. She became aware that her vision was being censored and managed to escape the police and a murderer who was invisible thanks to his religious costume by praying, hiding her from their sight to avoid offence. After the Doctor muted the Monitor to free everybody from her control, Peri returned with him to the TARDIS despite her expecting that they would have to stay and overthrow the government. (PROSE: See No Evil)

Offended by the Doctor's response to her culture shock on Dramos in 3174, Peri left him to explore the Habitat on her own and was welcomed into Human First's inner circle, White Fire, after attending a rally which was broken up by the Adjudicators. She was given weapons training and ordered by Draker to kill Darbokians during a riot, after which she learnt from Kane that White Fire supported the extermination of all non-humans and almost shot Avron Jelks because of her discomfort at what his group had made her realise about herself. Following the deaths of Jelks and Garon, Peri and the Doctor left, although Peri had hoped that Kane could have joined them. (PROSE: Burning Heart)

Peri asked the Doctor to take her to Kew Gardens, (PROSE: The Mark of the Rani) but the Master's time distortion caused them to land in 19th century Killingworth where they became aware of the violence caused by the First Rani's mission to restore calm to Miasimia Goria. Peri saved the Doctor after he was captured by the Master and the Rani and collected herbs with Luke Ward to make a sleeping draught to sedate the Luddites, a task which led them to Redfern Dell where Luke was turned into a tree by one of the Rani's land mines. The sleeping draught was ultimately unnecessary thanks to the Doctor picking the Rani's phial from her pocket before she and the Master fled Earth. (TV: The Mark of the Rani)

After leaving Killingworth, Peri was arrested and tried for the murder of Professor Mis'Kin Karac as a gun had been forced into her hands before the shooting. She was represented at trial by the Doctor, who realised that Karac's assistant was responsible and deceived him into confessing to the murder at court by threatening him with the actual murder weapon. As a result, Peri was released. (COMIC: The Forgotten)

Peri and the Doctor travelled to 1932 New Orleans where the Doctor left Peri to eat at the Legendre Lounge whilst he continued to follow the signal of a crashed Mykosian Pod. She bonded with Cassandra Legendre over their complicated relationships with their stepfathers and was attacked by zombies as she was thinking once more about leaving the TARDIS, prompting her to go after the Doctor and save him and Madame Ledanois. They learnt that Cassandra was being controlled by a Mykosian pendant which used her to turn people into zombies ahead of an invasion and returned it to the Mykosian pilot, whom Peri and the Doctor agreed to take home. (PROSE: Mardi Gras Massacre)

Attempting to make up for some of their recent rough journeys, the Doctor tried to take Peri to London in 1899, but they instead arrived in Africa during the Boer War where they narrowly saved Winston Churchill from an assassination attempt. After a brief stint in a Boer prison, they travelled to 1936 to make sure Churchill was safe, posing as the children of their 1899 selves, and Peri was briefly captured by Joachim von Ribbentrop. She was able to escape and uncover evidence of a conspiracy of high-ranking British citizens with Nazi sympathies, simultaneously preventing the would-be Edward VIII from dismissing the government so that he could marry Wallis Simpson, which was part of a complex plan by the Players to change history for the sake of it. (PROSE: Players)

For Peri's birthday, the Doctor took her to Las Vegas in 1971 to see Elvis Presley perform and promised her that her wish would be his command for the night. He left her before the performance, claiming that he was getting her any cocktail, and returned with Presley's autograph after stopping the Mongarians' plan to sell clones of him. (PROSE: Priceless Junk)

Peri suggested that the Doctor get medical help after he felt a time slip in his subconscious and they went to Space Station Camera to see Joinson Dastari, but the Sontarans had attacked and they found only Jamie McCrimmon aboard. The trio travelled to Seville to save the Second Doctor from Dastari and Chessene and went after him after he was temporarily transformed into an Androgum, but they were captured. Dastari freed Peri and the Second Doctor upon realising that he had made a mistake in augmenting Chessene and, with Peri's help, the Sixth Doctor tricked Chessene into trying to use the Kartz-Reimer module, killing her. Because of their experiences with Shockeye, the Doctor decided that he and Peri would adopt a vegetarian diet. (TV: The Two Doctors)

The Doctor tried to take Peri to see her family, but the TARDIS arrived in 1981 Washington DC where he became aware of the creation of the Savant and got Peri and Bob Salmon to help steal it from Sarah Swan. She considered leaving the TARDIS because she was tired of being frightened, with the Doctor agreeing that she deserved a better life, only to change her mind and decide once and for all that she belonged at the Doctor's side. Following the defeat of Swan and the Savant, Peri and the Doctor said goodbye to Charles Peters, who wrote the story of what happened as Blue Box with Peri's surname changed to Smith. (PROSE: Blue Box)

Arriving on Belstar instead of Exar 3, Peri and the Doctor were shot at by the Debans and rendered unconscious by a moisture evaporator, after which the Doctor was tasked by Ranon with recovering a blue rock from the Tower of Selsor to help them defeat the Siros. Peri joined him and found the trap door which led to the blue rock by touching a nugget of gold on the cave wall. Upon handing the rock to Ranon, they were permitted to leave. (PROSE: Battle Planet)

Colonel Latham was burnt to death whilst Peri and the Doctor were in the next room and they found one of Qualar's scales in the cellar when Sarah claimed that there were dragons down there. They encountered Qualar as they headed to the TARDIS and the Doctor defeated him and his dragons by blowing up Latham's house with them inside whilst he, Peri, Sarah and Harper were safe in the ship. (PROSE: Day of the Dragon)

Lost in the Fenlands in 1066, Peri and the Doctor were captured by Saxon rebels and brought before Hereward the Wake, who let them go and whom the Doctor realised was the same person as Harold Godwinson. The Doctor stopped the Normans from attacking by scaring them with a wind-up toy robot and he and Peri took their leave, with Peri wanting to know why the Doctor carried toy robots around in his pockets. (PROSE: The Real Hereward)

Peri and the Doctor visited Kyros following an invitation from Vama and informed him after they saw a creature die and turn bronze after eating some weeds. Whilst the Doctor spoke with him, Peri was attacked by Neltar, who had become a robot and whom the Doctor stopped with a freeze gun. Accompanied by guards, Peri and the Doctor destroyed the comet by which the weeds had arrived on Kyros, killing the weeds as they had been transforming people into robots. (PROSE: The Deadly Weed)

The TARDIS was pulled to Exclon by Vorton's gravity control and Peri and the Doctor were imprisoned, with the Doctor being ordered to inform the Time Lords that he had arranged a peace treaty with Exclon so that they could launch a surprise attack. They managed to get away, however, when the Exclons' spaceship attempted take-off and caused an earthquake before exploding. Peri fainted and the Doctor carried her back to the TARDIS. (PROSE: Vorton's Revenge)

The Doctor intended to take Peri to Palaran for a holiday, but the High Council overrode the TARDIS's controls and summoned it to Gallifrey where they gave the Doctor a mission whilst Peri slept inside. They were sent to Cambridge in 1996 to stop time from being manipulated and discovered that the Master was stranded on Earth and using Professor Thomas to build a time machine so that he could leave, but men from the Ipsilon Foundation went back in time and destroyed it. The Master escaped and Peri and the Doctor left for Palaran rather than return to Gallifrey. (PROSE: The Time Savers)

After Peri complained about the TARDIS's unreliability, the Doctor took her to England in the late 1970s so that he could acquire a screwdriver to continue his repairs and they heard about strange lights and sounds at the stone circle on King's Hill. They found that creatures from Valiark were hypnotising people as part of their plan to colonise Earth and defeated them by disturbing the electromagnetism of the stone circle protecting them, causing them to fade away and release the humans. (PROSE: The Mystery of the Rings)

Peri and the Doctor traced a signal to Stan's house and saved Maureen from a decompression bomb left as part of a trap. They learnt from Mick, whose taxi they hailed, of a series of killings committed by an Algernon stranded in Earth's seas and investigated, with the Algernon ultimately being killed by Mick. Peri and the Doctor left him with an unpaid fare of £436, heading off to the approaching Algernon rescue ship to save them a wasted journey. (PROSE: £436)

Feeling homesick, Peri asked the Doctor to take her to Earth and they arrived on Broadway in New York City.

The Doctor also learned Ravalox had been moved to protect secrets stolen from a higher species. The identities of those responsible remained a mystery. (TV: The Mysterious Planet)

On Thoros Beta
Arriving on the planet Thoros Beta in 2379 to investigate the distribution of dangerous weapons to the Warlords of Thordon, the Doctor and Peri found the Mentors were back at work, trying to make deals with a savage king named Yrcanos through a failed attempt to manipulate his mind. During their investigations, Peri was attacked by a creature called the Raak, and she was appalled to discover that a Krontep warrior called Dorf had been horribly mutated and chained up like a dog. Peri was further displeased to learn that Sil was present, and began to wonder if it was time for her to leave the TARDIS, as she was feeling homesick for her own time.

After a failed attempt to probe the Doctor's mind to see if the Time Lords had sent him to intervene on their behalf, Peri got separated from him after a botched attack on the slave Induction Centre. Whilst attempting to lose the guards, she encountered Matrona Kani, who offered to allow Peri to join her household of maids, as Kani preferred individuality in those who served her. Left with little choice, Peri agreed to serve the Matrona, and after being dressed in a smock and veil, was tasked with looking after the medication for Lord Kiv. However, she was discovered and taken away for interrogation. Peri was subsequently chained up at the Rock of Sorrows and tortured, before she was rescued by Yrcanos and Dorf.

While the Doctor pretended to be on the Mentors' side and helped Kiv transplant his brain to a deceased Mentor, Peri helped Yrcanos convince the Alphan resistance to fight against the Mentors. During this, Peri somewhat surprisingly developed fond and passionate feelings for Yrcanos, and she explained to him the concept of 'love', something she apparently felt towards him. Yrcanos became equally fond of Peri, and he quickly decided he wished to marry her and make her his Queen.

When Peri was captured with the rest of the resistance, she was selected to become the new host body for Lord Kiv. Before being taken away for examination by Crozier, she shared a final fond moment with Yrcanos, briefly holding his hand before she was escorted under guard to the laboratory. (TV: Mindwarp) Unaware that she was to become Kiv's host body, Peri was at first relieved to discover that she was not to be executed, (PROSE: Mindwarp) and she was examined by Crozier, who took measurements of her skull and had antigen tests done. Incorrectly assuming that she was being given a premarital medical examination for an arranged marriage, Peri protested that she was not marrying anyone. Crozier expressed his approval of her spirit and strength, and remarked that he would try to retain those personality traits of hers if possible. Upon hearing this, Peri's expression grew more puzzled and worried, as she silently pondered what exactly was being planned for her

After the tests were completed, Peri was initially pleased to hear that she had been found to be a perfectly fit and healthy candidate, but she was alarmed when she was then strapped to the examination bed she was lying on. Peri barely had time to angrily exclaim "Hey!", before she was then gagged by Kani and Crozier, who stuffed a cotton swab in her mouth and secured it in place with a wide red-orange bandage wrapped over her lips and lower face. Crozier informed the struggling Peri that she was perfect for his finest experiment. Crozier then ordered that Peri's head be shaved, in preparation for his plans to attempt direct transference. Horrified by this, Peri screamed into her gag, but her muffled pleas were ignored as all her hair was cut off by the Matrona. (TV: Mindwarp) When the shaving was completed, the terrified Peri was glad that she at least could not see herself with her now completely bald skull. (PROSE: Mindwarp) She was then sedated, whereupon her gag was removed and the brain alteration helmet was placed on her smooth hairless head.

Instead of planning to surgically remove Peri's brain and replace it with Kiv's, Crozier had decided to attempt what he had always wanted to achieve and directly transfer the contents of Kiv's mind into Peri's brain. This process would completely erase Peri's original memories and personality, and effectively brainwash her into becoming Kiv. The Doctor attempted to reach the laboratory and stop the operation, but he was taken out of time by the Time Lords before he could save Peri, leaving Yrcanos to rush to the lab in an attempt to rescue Peri. However, by that point Crozier had already begun to operate on the unconscious Peri, commencing the experiment to turn her into Kiv. (TV: Mindwarp)

Fate
Despite her apparent death, a number of varied fates for Peri existed, due to the temporal manipulations of various competing factions of Time Lords who each devised different ways to rewrite her life. According to a Time Lord who visited the Sixth Doctor and a version of Peri living in Los Angeles in 2009, at least five versions of Peri were removed from the timeline prior to the death of the original. (AUDIO: Peri and the Piscon Paradox)

The original
The mind transfer experiment was successfully completed with Lord Kiv's own consciousness transferred directly into Peri's brain, something the Doctor viewed during his trial. Peri's original personality and memories were erased in the process, and her entire mind was now a perfect copy of Kiv's. With all memory of who she once was gone, the Kiv-possessed Peri was delighted with the results of the mind transfer and she revelled in the sensations of her body. However, Yrcanos, who had arrived too late to save Peri from the experiment, due to being trapped in a Time Bubble by the Time Lords, burst into the laboratory, prompting Peri/Kiv to order the guards to protect her. Horrified and heartbroken upon discovering what had happened to Peri, Yrcanos began firing wildly in the lab, apparently killing Peri/Kiv in the process. (TV: Mindwarp) The Time Lord encountered in 2009 likened this to an assassination, strongly implying that it was orchestrated by the Time Lord faction behind the trial as a way of removing a potential witness who could contradict the altered recordings played at the trial. (AUDIO: Peri and the Piscon Paradox)

The Warrior Queen
A faction within the High Council deemed Peri's death excessive and unnecessary and pulled her out of the timestream before her death, allowing Yrcanos to rescue her. (AUDIO: Peri and the Piscon Paradox) According to one account, she made Yrcanos wait with her on Thoros-Beta for a month as she believed that the Doctor would be coming back to collect her, something she continued to believe when she agreed to leave for Krontep. (PROSE: Bad Therapy) She and Yrcanos were married (TV: The Ultimate Foe) and it was on the day of their wedding that she accepted that the Doctor would not be coming for her. (PROSE: Bad Therapy)

Accounts differed on whether Peri was in love with Yrcanos (AUDIO: Peri and the Piscon Paradox; WC: The Eternal Mystery) or if the relationship was entirely one-sided. (PROSE: Bad Therapy) She brought peace and prosperity to Krontep and was considered mightier than her husband, ruling with both steel and compassion. (WC: The Eternal Mystery) As well as being the nominal queen, known in one account as Queen Gilliam, she was governor in her own right of seven planets and director of several health and education enterprises on Krontep and almost never had time off from her official duties as a result. (PROSE: Bad Therapy)

A Time Lord claimed that Peri and Yrcanos had three children: two boys and a girl. (AUDIO: Peri and the Piscon Paradox) According to one account, their daughter Yrcanthia gave them three grandchildren: Actis, Artios and Euthys, (COMIC: The Age of Chaos) whilst another claimed that Peri chose not to have any children with Yrcanos, who waited patiently for her to change her mind. (PROSE: Bad Therapy)

According to one account, Peri was reunited with a small and old Doctor twenty years after they parted ways on Thoros-Beta. She was bitterly unhappy with him for having abandoned her and refused to reconcile with him, claiming that she had had better things to think about than him whilst on Krontep. He left, accepting her decision. (PROSE: Reunion)

According to another account, Peri was suffocated by the regimented life of a queen and her twenty-five unhappy years of marriage and ran away to the Palace of the First Queen of Kr'on Tep where she continued her research into Petruska. Although she promised Yrcanos that she would return when he came after her, she used Petruska's time tunnel and was reunited with the Doctor in his seventh incarnation, whom she greeted with a slap, in London in 1958. She helped him defeat Moriah, after which she forgave the Doctor for leaving her and had him take her to the late 20th century where she went to travel Europe. (PROSE: Bad Therapy)

A further account stated that Peri returned to Earth following Yrcanos's death (TV: Vengeance on Varos) as she did not believe that the people of Krontep needed a figurehead anymore, with her disappearance being dubbed the Eternal Mystery. (WC: The Eternal Mystery) When she found herself on the remembered TARDIS with the Doctor, Peri thought back to her experience on Varos, and agreed to rejoin the Doctor in his travels, on the condition that he take her back to Krontep once a year to pay her respects to Yrcanos and check on her former people. (TV: Vengeance on Varos) On one such occasion, she was caught by Rex and invited him aboard the TARDIS. (WC: The Eternal Mystery)

According to another account, in which she was regularly visited by the Sixth Doctor, Peri remained on Krontep following Yrcanos's death and went into exile under the name Ranith when Actios and Euthys entered into a civil war which killed Yrcanthia, who had succeeded Yrcanos. She returned after the Doctor, Frobisher and Actis exposed Farlig's warmongering whilst under the control of a Nahrung and was reunited with her family, with the Doctor, to whom she did not reveal her identity, calling out to her from afar as he prepared to leave the planet, knowing that it was her. (COMIC: The Age of Chaos)

Dr Peri Brown
Feeling that forcing Peri to live out her days with Yrcanos was a fate worse than death, an incoming President arranged for another version of Peri to be removed from the timestream and given the same treatment as Jamie McCrimmon and Zoe Heriot: being returned home and having her memories of all but her first adventure with the Doctor wiped. Peri completed her studied at college, going on to earn a doctorate, and resumed her relationship with Davey Silverman, whom she married. Davey frequently beat her, kicking her on their honeymoon and pushing her down the stairs.

Davey's beatings were so severe that Peri had to undergo reconstructive surgery because of damage to her nose and found that she was unable to bear children. She ran away to Los Angeles and became a relationship counsellor because she wanted to help people, but she eventually did it solely to make money and came to host Dr. Peri Brown: Worrier Queen, a popular television series which she produced with Carburetor, her best friend. After divorcing Davey, she had two further failed marriages.

In 2009, Peri was reunited with the Doctor on an adventure that saw her interact with her younger self — she pretended to be an alien expert working for the government in order to protect the Web of Time, not revealing her future to her past self. She unintentionally appalled her earlier self by seeming to kill Zarl, despite the fact that he was actually the Sixth Doctor in a monster costume, and was teleported away rather than killed. Ultimately, she learnt about her other selves, and the Doctor apologised profoundly for how his people had tampered with her life. Offered a chance to travel with the Doctor again, she declined and returned to her life in Los Angeles in 2009. (AUDIO: Peri and the Piscon Paradox)

Earth with Yrcanos
Exercising mercy, the High Council distorted the Matrix's timeflow and removed Peri and Yrcanos prior to the mind transfer operation, sending them back in time to live out their lives on Earth in the early 1990s. Peri was happy to be back in the United States, where she and Yrcanos settled in California, and believed that Yrcanos coped better with the perplexities of the 20th century than some natives.

Peri became Yrcanos's manager when he decided to take up a career as an all-win wrestler and watched him from the crowd during his matches. Whilst doing so, she wondered what had happened to the Sixth Doctor as her memories of Thoros-Beta had become vague, but she was ultimately happy being in her original time and place. (PROSE: Mindwarp)

Overcoming Mandrake
Another version of Queen Peri, visited by the Sixth Doctor on Krontep, was revealed to have become a pawn of Mandrake, the Doctor's childhood imaginary enemy that became a mind parasite, transferred to Crozier's computer when the Doctor was connected to the machine, and then to Peri's body instead of Kiv. Oblivious of the fact, Yrcanos died seven days after the wedding, having been poisoned by Mandrake.

When the Doctor came to attend Peri's wedding, Mandrake had him thrown into the cells, where he remained for five years as Mandrake used Peri's body to prepare for a coup of the various kingdoms. However, since Peri was sterile due to her spectrox poisoning, none of the other rulers would marry "Peri" as she would be unable to continue the royal line. After five years, Mandrake poisoned Peri's own body, wanting to force the Doctor to transfer his mind to the body of princess Dirani of Hurn in exchange for a cure.

Eventually, after swapping bodies with Peri in order to force the mind parasite into submission with his greater strength of will, the Doctor managed to restore her real consciousness and save her life with an antidote he had prepared during his imprisonment. Following this, Peri rejoined the Doctor on his travels. (AUDIO: The Widow's Assassin)

Continued adventures
One of their first trips together in the TARDIS again was to Scotland during the 22nd century Dalek invasion. She wanted to stop the stoning of Ross Nicolson. The Doctor told her not to get involved in what was happening and accidentally got chosen to work in the Daleks' refinery. On board, Peri met Moira Brody who told her more of the situation. Whilst escaping the complex she met up with the Doctor as he broke in.

Peri and the Doctor joined Moira on her way north to the Orkneys. Walking by foot, she was infected by a Varga plant. She started to be influenced by the Varga and wanted to kill her friends. After being captured by the Daleks, Moira started testing her blood and Peri was cured in a Dalek facility. She then helped Moira and Curbishly to stop the Roboman Elite as Moira used the same technique she used on Peri to remember her past. (AUDIO: Masters of Earth)

The Doctor and Peri visited the College of Advanced Galactic Education so that the Doctor could get an honorary degree. She helped Lizzo when they encountered her after she was experimented on. After attending one of Professor Baxton's lectures, she followed her to the medical facility and she realised that Baxton was in fact the Rani in her new incarnation. Peri was subjected to another body-switching experience when an elderly Countess was transferred into her body, but listening to an audio diary Peri had made earlier forced the Countess to realise that what she and others were doing was wrong. Peri later gained an honorary degree in Botany. (AUDIO: The Rani Elite)

Possessed by Kiv
Another account suggested that Peri survived the assassination and continued to be possessed by the mind of Kiv until a new host body was selected. It was implied that her brain, which still housed Kiv's mind, was surgically transplanted into the new body by Cordelia Crozier. (PROSE: Sil and the Devil Seeds of Arodor)

Other
The other permutations of Peri and the reasons for their creation were not specified by the Time Lord. (AUDIO: Peri and the Piscon Paradox)

Undated events
While travelling with the Sixth Doctor, Peri encountered the Fielding brothers in an adventure involving an exiled Draconian prince. (AUDIO: The Avenues of Possibility)

At some point, Peri was taken to the Black Archive by UNIT to have her record as a companion of the Doctor taken, her memories of the visit were subsequently erased and she was sent on her way. (TV: The Day of the Doctor)

In March 2005, Peri wrote on the website Doctor Who? asking if anybody had information on the Doctor as she was interested in getting back in touch. (PROSE: Have You Seen This Man?)

Mysteries and discrepancies
During the Doctor's fifth incarnation, Peri spent a year as a guerrilla fighter while separated from the Doctor, who meanwhile headed a military organisation known as the Alliance. (PROSE: Warmonger)

The length of time that Peri spent with the Doctor was unclear. Some accounts  suggested her travels with the Doctor occurred over the space of months, whilst others stated that at least "a couple of years" had passed for her between her first encounter with Jamie McCrimmon and her second. (COMIC: The World Shapers) As noted above, she was also separated from the Doctor for as long as a year on one occasion (PROSE: Warmonger) and two years on another. (AUDIO: The Kingmaker)

Alternative timelines
In a parallel universe, the Valeyard accidentally killed the Fourth Doctor by time-ramming him, the Fifth Doctor was erased from existence, and thus Peri's first meeting with the Doctor was altered or dissolved. (AUDIO: He Jests at Scars...)

In an alternate timeline created when Rassilon joined forces with the Cybermen, the Fifth Doctor and Peri landed on Skaro, the home planet of the Daleks, only to find it conquered by the Cybermen. (COMIC: Supremacy of the Cybermen) Realising that the Cybermen had grown powerful to wipe out the Daleks, the Doctor led Peri away, (COMIC: Prologue: the Fifth Doctor) only for this timeline to be undone when a remorseful Rassilon joined forces with the Twelfth Doctor. (COMIC: Supremacy of the Cybermen)

The Doctor and Peri were almost forced to land at the Big Bang due to mysterious coordinates being sent to the TARDIS which the Doctor tried to investigate. Escaping the explosion, the Doctor and Peri arrived at a Vess warehouse, and learnt the full magnitude of the situation with the Seventh Doctor and Ace. The Seventh Doctor was melancholy when he saw her again, telling his younger self that he had never gotten used to time travel leading to his being reunited with old friends. However, Peri got along well with Ace. She was surprised that Ace referred to the Seventh Doctor as "Professor" but was amused when she referred to the Sixth Doctor as "Joseph," a reference to the musical Joseph and the Amazing Technicolor Dreamcoat. The Sixth Doctor and Peri went to investigate the higher levels where they found a delegation of Time Lords, however Peri vanished due to the Doctor’s travels being undone by the Master’s conceptual bomb. These events were erased when the detonation of the conceptual bomb was prevented by the Doctors and the First Doctor disabled the emergency system that had drawn some the Doctors to the Vess pocket dimension. (AUDIO: The Light at the End)

Personality
Peri enjoyed playing tennis, hockey and lacrosse. (PROSE: The Two Doctors) Peri was often exasperated with the Doctor's sixth incarnation (TV:Vengeance on Varos), but still cared for him. (TV: Attack of the Cybermen, The Two Doctors, Revelation of the Daleks, etc.. ) Over time, the two of them became more amicable with each other, (TV: The Mysterious Planet) especially after the death of Peri's mother. (AUDIO: The Reaping)

Although she typically relied on the Doctor, she showed that she was intelligent, such as when she figured the poison must own a cure, (TV: The Caves of Androzani) and when tricked a Paradise 5 computer into giving her food and drink. (AUDIO: Paradise 5) She showed such courage when standing up to enemies. (TV: Planet of Fire, Attack of the Cybermen, Revelation of the Daleks) She also showed compassion on many, even on aliens and on some opponents such as Lytton. (TV: Attack of the Cybermen) She mourned the death of Kamelion even though he was an android, (TV: Planet of Fire) proved a capable one as a big sister figure to Erimem. (AUDIO: The Veiled Leopard), and also felt remorse on killing a mutant victim of Davros. (TV: Revelation of the Daleks) She was remembered by Krontep as leading with iron and compassion, and was regarded as being mightier than her husband. (Webcast: The Eternal Mystery)

Peri began to develop fond and romantic feelings for the warrior king Yrcanos, whom she subsequently fell in love with. (TV: Mindwarp) Following her rescue on Thoros Beta, Peri married Yrcanos in a least one timeline, (TV: The Ultimate Foe) and later bore his children. (COMIC: The Age of Chaos) After the warrior king's death, Peri would regularly visit a temple dedicated to Yrcanos, once a year, to pay tribute to her late husband. (WC: The Eternal Mystery)

In one timeline, (AUDIO: Peri and the Piscon Paradox) Peri's entire mind was altered into becoming a copy of Lord Kiv's. This made her personality more ruthless, lustful and dictatorial, although Crozier made sure she retained some of her original personality's spirit and strength, and she also seemed to retain her dislike for the physical form of the Mentors. (TV: Mindwarp)

Appearance
Peri had dark, shiny hair which she usually wore short and straight (PROSE: The Mark of the Rani) but later wore long and curled. (TV: The Mysterious Planet, Mindwarp) During her time on Krontep, she wore her hair short again, (AUDIO: The Widow's Assassin) presumably due to having to regrow it after being shaved bald by Matrona Kani. (TV: Mindwarp) In her later years, she styled her hair long and straight. (Webcast: The Eternal Mystery) She had a trim young figure (PROSE: The Mark of the Rani) and was considered beautiful. (TV: The Caves of Androzani, Timelash)

She often wore shorts with a low-cut top whilst travelling with the Doctor, (TV: Planet of Fire, Attack of the Cybermen, The Two Doctors, etc.) but donned a royal yellow gown in 19th century Killingworth (TV: The Mark of the Rani) and a blue ensemble on Necros. (TV: Revelation of the Daleks) In her later adventures, she wore more conservative clothes. On Ravolox, she wore a flaxen and black blazer, a gold-coloured silk blouse and silver-grey slacks, (TV: The Mysterious Planet, PROSE: The Mysterious Planet) while on Thoros Beta, she was attired in pale blue culottes, a sleeveless pink wrap blouse and a short loose-fitting kimono-style jacket in pink, white and blue. (TV: Mindwarp) Whilst visiting the temple dedicated to her late husband, an older Peri wore a black ensemble, including a cloak with a hood. (WC: The Eternal Mystery)

Name
When asked about the name "Perpugilliam" in a 1986 interview, Nicola Bryant said: "I never warmed to the name Perpugilliam, but I like Peri as a name. John [Nathan-Turner] found it in a book. Apparently, in the Sixties, mothers in America were naming their children with particularly long ostentatious names. Obviously, John was using this to typify the kind of background that Peri had had, and the kind of mother she had."

- Nicola Bryant

The 1995 Cornerstone trading card misspelt her name as "Perpugillium". The same typo was made in Dalek Combat Training Manual in 2021.

Perpugilliam is an old family name (PROSE: Players) and a family tradition. (PROSE: A Town Called Eternity)

In the audio story The Bride of Peladon, Peri claims her name means "she who lives in the hills".

In the short story A Handful of Stardust, Thomas Digges says that Perpugilliam is Latin for "by a handful". Digges ends A Perfit Description of the Caelestiall Orbes with the inscription "Per Pugilliam Pulvis Sidereus", which Peri translates as "by a handful of stardust".

BBV Productions
Using her actual English accent, Nicola Bryant played "Miss Brown" (who was never actually referred to by name on-screen), an obvious analogue to Peri, in three BBV Productions videos in the series: Summoned by Shadows, More Than a Messiah and In Memory Alone. Later videos in the series would make clear that the Stranger series did not take place in the Doctor Who universe and that Peri and Miss Brown had no connection with each other. Bryant also played Elenya "Ellie" Brown, the girlfriend of Colin Baker's character, TV weather forecaster Arnold "Arnie" Davis, in another BBV production, the non-Doctor Who The Airzone Solution.

Longevity
Counting audio and televised adventures together, Peri effectively shares the longest-serving companion title — both in terms of number of stories and recorded time — with Ace. As they are tied, the title essentially alternates as new stories are released. Her nearest rivals are Jamie McCrimmon, Charley Pollard and Nyssa. Nyssa's appearances are considerably more frequent than Jamie's so she represents the only potential threat to Peri and Ace's record-breaking number of appearances.

While she clearly eclipses the amount of time Sarah Jane Smith has been seen or heard as a companion, Peri is easily outpaced by the character of Sarah, due to Sarah's latter-day appearances as a solo character.

Peri was also incredibly prolific within the Sixth Doctor's era on television. Terror of the Vervoids is the only television story of that era in which she does not appear, though within that story, she is still mentioned.

American accent
While Peri is supposed to be an American, her English accent often slips and her American accent wanders between different regional accents. She sometimes uses phrases and pronunciations that Americans would not use, such as "lift" instead of the American "elevator".

Indeed, the Attack of the Cybermen DVD commentary maintained that it was mandated that Peri only use British slang to avoid confusing the audience. This may have worked for the British audience but, as Peter Davison pointed on on the DVD commentary for Planet of Fire, it had the opposite effect on American viewers. They could spot Bryant's fake American accent — or, really, any British actor's attempt at American — with ease. This was one of the principal reasons that Davison fought hard against adding an American companion to the show. This idiosyncrasy of language did not end with the TV series, as it can be heard in several audio dramas also.

According to Nicola Bryant on the DVD commentary for Planet of Fire, there was an active effort to cover up the fact that she was not, in fact, American. She recounted there how John Nathan-Turner insisted she use her American accent when making public appearances or appearances that could have been monitored by the press. At least during the recording of her earliest serials, like Planet of Fire, she was even required to use the American accent when she broke character between takes.

It's unclear how long this obfuscation lasted, but evidence for the subterfuge can be heard on a clip from Breakfast Time broadcast the day the first episode of The Twin Dilemma aired. During the interview, the interviewer asserted that as a "little girl in America" Bryant used to watch Doctor Who and dream of being a companion. Bryant, who used only a very mild English accent during the interview, failed to correct the interviewer or to even look as though the interviewer had made an error. Near the end of the 1984 production block — which is to say after the recording of Season 22, but probably slightly before its airing — Bryant gave a radio interview in which she used her natural British accent. (AUDIO: Doctor Who at the BBC Volume 3)

Relationship with her stepfather
The idea of Howard Foster sexually abusing Peri is one never considered by the production team on Planet of Fire and does not have resonance in audio and print literature beyond the novel Shell Shock. Nicola Bryant says that the idea, as envisioned by Fiona Cumming, Dallas Adams and her was to suggest that she and her stepfather had an appropriate but friendly relationship. Indeed, according to Bryant, Peri much preferred the company of Howard to that of her mother. (DCOM: Planet of Fire) However, the character of Peri (or at least one aspect of Peri) was still destined for an abusive relationship as revealed in AUDIO: Peri and the Piscon Paradox.
