Liv Chenka was a companion of the Seventh and Eighth Doctors.

She was a Kaldoran human who travelled as a medical technician. She met the Seventh Doctor aboard the Lorelei and later met the Eighth Doctoron Nixyce VII, joining him and Molly O’Sullivan in the TARDIS after encountering them aboard the Orpheus.

Liv continued to travel with The Doctor after Molly’s departure and death, later being joined by Helen Sinclair whilst tracking the Eleven.

Liv was the daughterof Kal Chenka and his wife (Absent Friends) and sister to Tula, who she always felt was the favourite. The family lived in Kaldor City, although Liv never felt like she belonged there, spending most of her days looking up at the stars and longing to be away. (Escape from Kaldor) As a child, she was sometimes known as Livvie, which she hated. (Love Me Not)

Her fatheroften took her hiking through the mountains, (The Sonomancer) where he would play music which he believed centred him with nature. (The Robots of Life)

Liv studied medicine at college (Escape from Kaldor) and took extracurricular modules in biomodelling, stem cell usage and advanced operating procedures. (The Robots of Life) She was part of a group of friends that included Bas Pellico and Kit Laver. Whilst she remained close to her parents, Tula pursued a career in robotics with the Kaldor City Company and never returned home nor called due to her father’s apparent dislike of robots. Liv found it impossible to live up to her and saw how much her absence hurt her father. (Escape from Kaldor)

She trained at Kaldor City Hospital, where she was mentored by Arak Varren. During her final cadaver exam, her hands shook so much that she could barely hold her laser scalpel. (The Robots of Life) Upon qualifying, she looked to have herself assigned to long-term postings away from Kaldor. (Escape from Kaldor) As a result, she was away working when her father died. She blamed herself, believing that she would not have misdiagnosed him as the med-tech had, and was upset that she was never able to say goodbye. (Absent Friends)

Kal’s funeral was paid for by Tula, who did not attend. This left Liv bitter and she cut contact with her for ten years, feeling abandoned. However, she did not hate her sister. (Escape from Kaldor)


Liv served aboard the Lorelei cargo spaceship. She encountered the Seventh Doctor shortly before a group of Voc robots began to attack the crew of her ship. She helped The Doctor to discover that the Voc robots were not behind the attacks, and found that it was actually the ship’s security chief, Farel, dressed as a robot when instigating an attack. Liv and the Doctor then prevented Farel from crashing the Lorelei into Ventalis. Liv stayed behind on Ventalis after The Doctor had departed. (Robophobia)

The Doctor’s TARDIS took a liking to Liv during this encounter and talked with The Doctor afterwards. She asked The Doctor if he could take on Liv as his companion to which he replied, “Another time perhaps, but not now.” (Black and White)

Following the events on the Lorelei, Liv wrote a debrief and signed a non-disclosure agreement. (Escape from Kaldor)


Liv was present on Nixyce VII when the Daleks invaded. She was used by The Dalek Time Controller to be a source of compassion amongst the natives of Nixyce VII. It was here she encountered The Doctor for the second time, although she did not recognise him at first because he had regenerated since they last met. Eventually she was convinced of his identity and she helped him with his plans to turn The Daleks against an Eminence fleet nearby. (The Traitor)

Liv eventually fled The Dalek invasion in the bowels of a cargo ship, but suffered severe radiation poisoning which compromised her metabolism and condemned her to death, be it through embolism or renal failure, whichever would strike first. (The Reviled)

Because of this, she signed up as a med-tech on the science vessel Orpheus and went into cryo-sleep on board for a thousand years. She awoke when the Orpheus had reached the edge of the universe. Liv once again met The Doctoron board the Orpheus, shortly before it came under attack from the Eminence, and it began to possess the crew. Liv planned on blowing herself up next to a piece of the Eminence in order to stop its plan, but was rescued by The Doctor and Molly O’Sullivan. She promptly joined them on their adventures. (Time’s Horizon)


Liv travelled with The Doctor to London in the 1970s, where she helped him to defeat The Master and the Eminence. After they were defeated, The Doctor made Liv stay behind in London with his companion Molly at his home in Baker Street, due the fact that they had met out of order — he had to play out the events in which Liv first met him on Nixyce VII. (Eyes of the Master)

When Molly disappeared, Liv suspected the worst and was able to fashion a crude communications device from the technology of the era, and sent out a distress call which was intercepted by Coordinator Narvin of the Celestial Intervention Agency. (The Death of Hope)

Liv was later sent by Narvin to help The Doctor fight The Master and the Eminence, sending her to Ramosa, where she worked to improve the conditions of the humans refugees of the Eminence War who had settled there, alongside the native scorpion-like Ramossans, who began to despise their visitors and the danger they placed them in. When the humans were isolated into a “quarantine camp”, Liv worked to make conditions livable and acted as a medic to the injured, while waiting for The Doctor to arrive. Once he did, together, they worked out a way to make sure the humans escaped an incoming Eminence attack, however, their plan failed resulting in the complete destruction of the Ramossans, their world, and the Master securing the refugees for his own purposes. (The Reviled)

Scared by The Doctor’s determination to avert the war, but willing to go along with him, she snuck aboard the private research complex of Professor Markus Schriver, the man responsible for the eventual creation of the Eminence itself, and posed as an assistant sent to him by the Ides Scientific Institute. She became concerned by his mental health but facilitated a meeting between him and the Doctor, which only reinforced the fact he was slowly losing his sanity. Her cover was blown by the arrival of Dr. Sally Armstrong, working for The Master, and she would have died during a neural extraction procedure if Shriver’s insanity hadn’t caused him to trap Sally inside a second chamber and program the computer to decide which one would undergo the procedure through random chance. Due to her condition, Liv was ready for death, but in the end survived when the computer “chose” Sally instead. She was then taken by The Master instead to play nursemaid to Molly, who was suffering from the mental conditioning and retro-genitor particles that Master had assaulted her with. (Masterplan)

Liv was present on Earth as The Master set up his final endgame, with the eventual result that all of humanity was slave to his will, only able to keep Molly stable and calm during her moments of wakefulness. When Narvin, working with The Doctor, tried to rescue her, she tried to shoot The Master with a hidden firearm, but his hypnotic abilities caused her to believe she was finally succumbing to her illness. However, The Master revealed it was all in her mind, and that her continuous exposure to the particles inside Molly had in fact cured herof the radiation poisoning.

She was eventually rescued from the Master’s grasp by The Doctor, and sent by him to take control of a nearby television communications hub, which proved essential to ending The Master’s control over the Earth, and defeating the Eminence in the here and now. Afterwards, she was invited on board the TARDIS as a full-fledged companion, even being given a TARDIS key of her own, and said her farewells to Molly, who was to be sent home by Narvin for her own protection. (Rule of the Eminence)


She visited London 1921 when The Doctor was looking for Molly. She hated looking out of place in her usual attire, so wore clothes of the era. The Doctor then asked her to take Martin Donaldson out on the town. When Martin took her to see a Buster Keaton film she pointed out the flaws in it. The Woman was looking for her. (A Life in the Day)

She went to Paris with The Doctor when he tracked the TARDIS there. She talked to Georges Legrand which led her to Adelaine Dutemps. She kicked down The Doctor’s artist friend’s apartment door. She told The Dalek Time Controller about the outcome of the Eminence war. (The Monster of Montmartre)

Liv was disgusted that The Master was working with The Daleks. She got used to being taken prisoner by the Daleks. She expected The Masterof being better than using The Daleks. She attacked The Master with the perfume The Doctor had given her in Paris, and stole his Tissue Compression Eliminator. She went to Moscow with him to find The Doctor. She blew Molly O’Sullivan’s cover there. (Masterof the Daleks)

She became worried after Molly became ill after they arrived in the Eye of Orion. The Time Controller then took her to see Markus Schriver’s final experiments. She witnessed the birth of the Eminence. The Dalek Time Controller wanted her to transfer his mind into the gasses the Eminence were composed of; she wouldn’t. She wanted The Dalek Time Controller to die to save billions. She took Molly home after her sacrifice. (Eye of Darkness)

With The Doctor, she visited several England-themed planets. (Absent Friends)


After years of travelling with The Doctor, (Absent Friends) she was brought to Gallifrey with The Doctor by Cardinal Padrac after the Eleven escaped. Although some of the Time Lords were prejudiced towards her because she was human, Liv was able to see through a Time Lord trick the Eleven had used to hide from the authorities.

She helped Padrac search the Time Lord Academy for evidence against Kiani. Padrac was complimentary towards Liv for travelling with The Doctor. After the Eleven created a state of emergency, he took her hostage. (The Eleven)

When The Doctor traced a temporal anomaly to London 1963, she helped Helen Sinclair to translate some documents from ancient languages using the TARDIS telepathic circuits. She discovered references to the Red Lady. (The Red Lady)

In Florence, 1639 she helped the Cavalli in his investigations. (The Galileo Trap)

She was again used by the Eleven as a hostage against The Doctor. She managed to stop Helen getting dissected. (The Satanic Mill)

After this ordeal, The Doctor took her and Helen to Stegmoor to recuperate. She was the first to notice the Voord spaceship. She almost ran over Ishtek, which alerted the Voord to human presence. (Beachhead)

She wanted to rescue Caleera from the machine that she was kept in. She went off to find the Eighth Doctor. She later helped a set of slaves escape from confinement. (Scenes From Her Life)

When they landed in San Francisco 1906, she asked Helen to take her around to find The Doctor as she knew the time period better. When Helen was kidnapped she went back to find her. She went ahead to unlock the TARDIS to help The Doctor’s plan but was trapped underneath a building. (The Gift)

She helped The Doctor to discover why the planet Syra was about to explode. In doing this she distracted the Eleven, and started a fight with him in mining robots. She was about to be thrown down the mine until River Song stopped the Eleven. (The Sonomancer)

The Doctor, Helen and Liv went to Calcot on 1998. She helped The Doctor investigate a mysterious set of nuisance calls. While there, Liv received a call from her father, who was long dead. When The Doctor told her the calls were temporally displaced she took advantage of this to tell her father how much he meant to her. (Absent Friends)

Liv was placed in 15th century Prague in order to find a piece of the Doomsday Chronometer. Apolena took her to the forest and told her about the stories Osm told her. She then met River Song again, and helped her find out a bit more about the Chronometer. (The Eighth Piece)

She was to be killed by the Clocksmith who wanted to encase her in molten metal, but River managed to save her but then the Clocksmith’s shop went up in flames and River took her away from the time zone to Rome in 2016. There she met up with Helen again, just before the Clock was reassembled and the museum which they were in collapsed. Helen and Liv managed to get back to the TARDIS just in time to see the Eight regenerate. (The Doomsday Chronometer)

She found it difficult to deal with the Nine in his post-regenerative state, believing him to be The Doctor but his erratic behaviour caused some strain before she realised who he really was. The Nine left her behind on Gallifrey where she met with Padrac, who told her what he had stolen. She realised that Padrac was working with the Eleven after she saw a picture of Stormblood on his council and the fact that he was referring to Caleera when he was taken not the Eleven. Padrac then took her to the Crucible of Souls to show off his work. (The Crucible of Souls)

She, The Doctor and Helen were trapped in a scape capsule careering into the nontime of a murdered future by Padrac. She got moody at The Doctor for leaving her and Helen in Rome 2016 while The Doctor was angry and hurt that she and Helen had gone off with the Nine in his TARDIS and was offended that they had believed one of the most dangerous, insane criminals in Time Lord history was him. After The Doctor couldn’t fix the Time Ruders but found some sails which could capture the Time winds. She was determined to find a way to get out of the situation. They jumped out of the pod and rode the shock wave back into normal time. (Ship in a Bottle)

Liv and Helen appeared back in the normal universe with only five minutes of oxygen. They were rescued by a Time Ship which traversed the vortex and started to disintegrate. She managed to programme the ship to deposit them on Earth in the 25th century. River managed to get her to Gallifrey where she got to the TARDIS she left with Veklin to find The Doctor. (Songs of Love)

Helen and Liv went exploring New York. When they went to the main museum, they saw a picture of the TARDIS and a Weeping Angel which had been bequeathed by them. At the museum. They started to hear about the Weeping Angels. The Monk projected an angel which then became an angel in front of them. Veklin came to save them and told her that she was the one giving them clues. (The Side of the Angels)

She was tasked in The Doctor’s plan to stop Padrac by destroying the transduction barriers. When she got into the city, she got a message from Caleera to destroy the Capitol shields instead. After Helen crashed the Battle TARDIS, Liv decided to help the injured Time Lords, before The Doctor told her that they were going to search for Helen. (Stop the Clock)


While the TARDIS calculated the route taken by the Battle TARDIS Helen was in, the Eighth Doctor was summoned by Winston Churchill to investigate a mysterious abnormality to which the RAF were losing pilots. Liv ended up flying through the breach and was used by the Heliyon as a bargaining chip against The Doctor, who thought Liv was dead. After defeating the Heliyon, Liv was saddened to hear about the death of the pilot with whom she was a prisoner, calling his death a waste. (Their Finest Hour)

The Doctor and Liv followed Helen’s trail, but were dragged off course by a disturbance in the vortex, caused by the experiments of Cornelius Morningstar. After Morningstar’s scientific consultant, Stralla Cushing, killed him, Liv and the Doctor worked to find her. (How to Make a Killing in Time Travel)

When the TARDIS finally tracked down Helen, The Doctor and Liv ended up at Rykerzon, a prison, where Liv was interrogated. She was broken out by inmates attempting to escape the Kandyman. Then, she and the Doctor finally reunited with Helen, who had also been an inmate there with the Eleven. (World of Damnation) The Doctor was initially sceptical that Helen was still the same person that they knew, but Liv was convinced by her. After defeating the Eleven and the Kandyman, Liv and the Doctor happily welcomed Helen back on board the TARDIS. (Sweet Salvation)


Seeking a holiday after recent events, the Eighth Doctor took Liv and Helen to the opening of a new leisure centre on Kaldor, hoping to also arrange a reunion between Liv and her sister Tula. After a distraction caused by an aborted attempt to rob the complex that reverted the robots to a setting where they would destroy all life in the complex as part of anearly attempt at pest control, Liv decided to remain on Kaldor for a year to patch things up with her sister, arranging to rejoin The Doctor and Helen later after they travelled forward in time by one year after saying goodbye to her.

At the end of her yearon Kaldor, Liv returned to where the TARDIS had left and rejoined The Doctor and Helen, telling them that she would tell them about her experiences there later. (Escape from Kaldor)


The Doctor took Liv and Helen to experience the Christmas season in Salzburg, arriving on Krampusnacht. As Christmas was not celebrated on Kaldor, Helen showed Liv around and explained the holiday to her. The three became aware of the presence of Krampus and were able to defeat it, (Better Watch Out/Fairytale of Salzburg) with Liv using herone wish to have Artron (Day of the Master) restore Helen’s youth after she spent decades learning to fly the TARDIS. (Better Watch Out/Fairytale of Salzburg)

The three materialised on a dying TARDIS after receiving a distress call from the Eleven, although Liv had no sympathy for him and did not wish to save him. They encountered one of the Ravenous, which chased Liv but was far more interested in The Doctor and the Eleven. The trio ended up on a nearby planetoid after escaping the TARDIS and were transported away by Rasmus. (Seizure)

Given her history with Time Lords, Liv asked Rasmus up-front if he was evil. On the Deeptime Frontier, she and the Doctor attempted a number of methods to destroy the corpse of a Ravenous, each failing. Liv and Helen were led into a TARDIS by the Nine, believing that it was The Doctor, (Deeptime Frontier) and were incarcerated as part of his collection.

Liv and Helen teamed up with fellow companions Charlotte Pollard, Bliss and theirold friend River to escape their confinement, managing to defeat the Nine thanks to Katarina. They were picked up by The Doctor and the Eleven. (Companion Piece)

Seeking answers to the Ravenous, Liv, The Doctor, Helen and the Eleven went in search of Professor Marathanga (L.E.G.E.N.D.) and, later, the gateway to the Ravenous’s prison on a Time Lord outpost. Liv was entirely distrustful of the Eleven, who claimed to have lost his other personalities and joined them as a companion. (The Odds Against)

Due to the Eleven’s presence, Liv began to consider that she might leave the TARDIS, with Helen agreeing to join her should she decide to do so. The two discovered that the Eleven had been lying about the disappearance of his other personalities. (Whisper)

The Eleven asked to be taken to Parrak to live as a hermit. On the planet, the TARDIS team encountered a decaying Master, who was eaten by the Ravenous. (Planet of Dust)

Whilst Helen was kidnapped by Missy, Liv met the War Master, believing him to be a Time Lord agent. After exhausting his use of her, he shot her and she regenerated thanks to the Eleven’s use of the Crucible of Souls to make food for the Ravenous. She later lost the ability and, after the Eleven was defeated, left in the TARDIS with Helen and the Doctor, who said that they would be stranded due to damage sustained by the TARDIS. (Day of the Master)


Stranded in 2020 London, Liv, Helen and the Doctor moved into 107 Baker Street where Liv met and befriended Tania Bell. Six weeks after arriving, she and Helen encountered The Curator twice, once at the TARDIS and again in a cafe. Helen encouraged her to get a job to help them pay the bills. She was unable to use her medical knowledge to get a job due to her inexperience with 21st century, medicine (Lost Property) but was able to get a job as a cashier at Sanjit’s convenience store thanks to housemates Aisha and Zakia Akhtar.

At the shop, Liv attempted to take a robber’s gun, resulting in herself and Sanjit being shot. Unlike Sanjit, Liv survived and was taken to the hospital where, after becoming conscious, Tania invited her to dinneron a date, to which she accepted. To cover up being from the future, she had to pretend to need crutches and physiotherapy. (Wild Animals)

Liv met Andy Davidson when he came to the house looking for Tania and later followed him to Church Street where they saw Mr Bird, who disappeared after the MedTech building exploded. Liv helped with the casualties and, after returning home, shared a meal with Tania and agreed that they should have a “don’t ask, don’t tell” rule with regards to their respective secrets. (Must-See TV)

The Doctor intruded upon Liv and Tania’s plans for dinner by inviting the entire house after he won £80,000 on You Either Know It or You Don’t, irking Liv. She chased after the Rakilians with Helen, Tania and Andy and gave The Doctor CPR after he was shot. Following his revival and the Rakilians’ banishment, she decided to tell Tania and Robin Bright-Thompson who she, Helen and the Doctor were. (Divine Intervention)

Liv accompanied The Doctoron a test flight in the TARDIS, along with Helen, Tania and Andy. They arrived in the same place 6 million years later and she and Andy went exploring. They found a control base, triggering a countdown, and were attacked by a sentinel, which they led to The Doctor and Tania. After they disabled it with rocks, The Doctor was horrified by Liv revealing she and Andy had spotted a map indicating similar robots across the world, as they were equipped with decontamination technology to wipe out life on Earth. Realising this was the purpose of the countdown, she and the Doctor returned to the control base where they learned the computer system had not heard from humanity in millions of years. They returned to the TARDIS, where The Doctor disabled the robots and took them all back to 2020. (Dead Time)

Liv reluctantly agreed to help Tony when he began to struggle with his memories and together with Helen deduced he was actually recollecting an event with the current Doctor who had travelled back in time. After realising his radio was connected to the past, Liv and Helen interfered with it using their TARDIS keys to send a message via morse code to The Doctor. (UNIT Dating)

Liv and Tania travelled back in time to 1941 with The Doctor, Helen and Akhtar sisters. Liv insisted on staying with Tania as she investigated an unexploded bomb set to be unearthed in 2020, discovering it as an alien stasis device which they prevented spreading over the street. (Baker Street Irregulars)

Liv travelled with The Doctor to 2050 to investigate the altered future, along with Helen, Tania and Andy. They were all immediately captured by forces opposing Divine Intervention and Liv was subsequently interrogated by Gemma Houlbrooke. The Doctor eventually convinced Gemma to release them and they returned to 2020. (The Long Way Round)


The Tenth Doctor told Gabby Gonzalez about Liv, along with several other former companions. (Vortex Butterflies)


On Kaldor, Liv felt that she did not belong and longed to explore the universe. (Escape from Kaldor) She was full of life when she was younger, but her life got hard and her struggles changed her. By the time that she was travelling with The Doctor, she said that she was not sure if she “actually [did] fun”. (A Life in the Day)

Liv was smart (Companion Piece), sarcastic and liked to be in control. (Escape from Kaldor) She rarely joked and considered herself to be a very serious (How to Make a Killing in Time Travel) and conservative person. (Their Finest Hour) She said that people generally liked her after getting to know her. (Sweet Salvation)

Liv found romantic situations uncomfortable, not being used to them. (A Life in the Day, Their Finest Hour) When The Doctor said that Liv was good at diplomacy, she asked if he had ever met her. (How to Make a Killing in Time Travel) She was willing to sacrifice her own life to save others (Time’s Horizon) and insisted that The Doctor let Molly do just that. (Eye of Darkness)

Liv was suspicious of the Nine when he impersonated The Doctor (The Crucible of Souls) and distrustful of the Eleven when he was travelling with them. The Doctor believed that she was an excellent judge of character (L.E.G.E.N.D.) and she bemoaned that she was always the one who stumbled upon surprise villains. (The Odds Against) She had also been the one to realise that Padrac was part of the Doom Coalition. (The Crucible of Souls)

She did not like snow and was initially resistant to embracing Christmas spirit. (Better Watch Out)

The Master described Liv as being delightful but dreary. (Eyes of the Master) The Eleven admired her honesty and claimed to “almost” like her. (Whisper)


Along with Thomas Brewster, Evelyn Smythe and Charlotte Pollard, Liv is one of four companions created by Big Finish Productions to be depicted travelling with or meeting two incarnations of the Doctor.
