Toshiko "Tosh" Sato was a member of Torchwood Three in the 2000s.

After being imprisoned by UNIT for assisting criminals under duress, Tosh was released by Jack Harkness under the condition that she work for Torchwood for five years. She was quiet and unassuming, generally using her computer genius to avoid exposure and to assist her colleagues. Nonetheless, she proved herself to be a field agent capable of taking on her own missions and projects. She had feelings for Owen Harper that she did not make known to him for quite some time.

She suffered a gunshot inflicted by Gray and died saving Cardiff from nuclear meltdown. However, she felt that she had failed Owen, who died unaware that she too was moments from death.

Biography

Early life

Tosh was born in London in July 1975. In 1977, her mother and father, who had both been in the RAF, moved with her to Osaka (TV: Greeks Bearing Gifts; AUDIO: torchwood_cascade_CDRIP.tor) where they lived with her grandmother. (PROSE: Trace Memory) She had a brother who died and whose death she felt responsible for, believing that she had abandoned him. (AUDIO: torchwood_cascade_CDRIP.tor) Their grandfather had worked at Bletchley Park. (TV: Greeks Bearing Gifts)

Whilst living on Osaka, Tosh was read fairy tales about Sentaro. At the age of five, she met Michael Bellini, who had time travelled into her bedroom, and was threatened by a Vondrax before Bellini left. (PROSE: Trace Memory) She was a big fan of Steve Ross's comic books, (AUDIO: Believe) was obsessed with Tetris (AUDIO: Zone 10) and was part of her school's Maths Club. (TV: Adam) In 1986, the Satos returned to the United Kingdom. (TV: Greeks Bearing Gifts)

When Tosh moved into her own flat, she chose not to have a flat-warming party as there was nobody that she wanted to invite. (TV: Adam) She got a job at the Ministry of Defence's Lodmoor Research Facility. (TV: Fragments)

Career at Torchwood

Joining Torchwood

Tosh was blackmailed by Milton, who had taken her mother hostage, into stealing the Ministry of Defence's plans for a sonic modulator and building one. She managed to do so, improving upon the design as the plans were incorrect, hence their being shelved. Shortly after handing it over, Tosh was arrested by UNIT and held indefinitely and without hope of a trial or appeal. She did not know her mother's fate as UNIT refused to give her any information.

After some time, Tosh was visited by Jack Harkness who told her that her mother was okay and that Tosh would be held at UNIT forever to make an example of her. He promised her her freedom in return for five years' work at Torchwood Three, an offer that she took. (TV: Fragments)

Early years

Tosh worked alongside Jack and Suzie Costello, with whom she was temporarily frozen in a time bubble in the Hub for a day on the orders of Yvonne Hartman, who remarked that she was "cute". (AUDIO: One Rule) She attempted to find out Jack's identity, finding that there had been no US citizen by that name for fifty years. (TV: Day One) She developed feelings for Tommy Brockless, whom they unfroze once a day every year. (TV: To the Last Man)

They were joined by Owen Harper and Ianto Jones. (TV: Fragments) From the moment that Owen joined Torchwood, Tosh had to step in to save him, including posing as a doctor during his second week due to a hangover (TV: Fragments) to perform an autopsy on the Space Pig, which injured her, at Albion Hospital. She met the Ninth Doctor who told her the truth about the pig. (TV: Aliens of London)

Tosh at Rockfell Hall. (AUDIO: The Vigil)

Although Tosh considered new recruit Sebastian Vaughan to be a friend, he was unkind and sometimes racist to her, telling her that the team found her and her obsession with technology boring and that there was no real difference between the Chinese and the Japanese.

Tosh investigated the cortex leeches, which Sebastian told her was obsessive and unnecessary. They attacked Sebastian, who asked Tosh to kill him and told her that she was and would always be unsuited to Torchwood after she refused. Tosh took his body to Madeline Vaughan at Rockfell Hall, blaming herself for his death, and saved Madeline from Sebastian's leech-possessed corpse. (AUDIO: The Vigil)

Later years

This section's awfully stubby.

Info from Random Shoes needs to be added

When Torchwood went to crime scenes to test the resurrection gauntlet, Tosh was the one to ask questions. She covered up the killing of a hospital porter by a Weevil by planting a false alibi and changing the hospital's rota, something that she told Gwen Cooper when she entered the Hub, telling her that it was her job to do so. (TV: Everything Changes) She was more sympathetic to Gwen on her first day than her colleagues and helped defeat the Sex Gas that had possessed Carys Fletcher, cornering it at the Conway Clinic. (TV: Day One)

Tosh helped Jack, Owen and Gwen track down the quantum transducer that Bernie Harris had in his possession, tracking him down and visiting his mother. (TV: Ghost Machine) She also helped to defeat the Bruydac, (PROSE: Another Life) Scotus and his alien tapeworms (PROSE: Slow Decay) and Lisa Hallett, whom she shot whilst she was in Annie Botchwell's body. (TV: Cyberwoman) She provided her teammates with valuable information on the Fairies (TV: Small Worlds) and the CARU Clinic. (AUDIO: Hidden)

She joined the team on a visit to the Brecon Beacons to solve a number of disappearances. In Brynblaidd, she and Ianto were kidnapped by the cannibals as part of the harvest, (TV: Countrycide) an ordeal that she had nightmares about afterwards. (AUDIO: Broken)

Jack cheers up Tosh after Mary's death. (TV: Greeks Bearing Gifts)

Tosh had a relationship with the Arcateenian known as Mary, who tried to use her to gain access to her technology that Torchwood had confiscated. Their relationship was the first one that Tosh had had with another woman. To drive a wedge between her and her teammates, Mary gave Tosh a telepathy pendant, which she chose to destroy for fear of its possible uses after Jack tricked Mary into teleporting into the Sun. (TV: Greeks Bearing Gifts)

Tosh investigated a series of strange deaths including one person who died by his head exploding on a bus to Gabalfa. She attended one of Simon's therapy sessions. She started coming here because of how she heard what he colleagues thought of her. After the session she talked to Simon about his situation. She later asked Daphne what had happened to her son Karl after being killed. Karl was keeping a record of the strange deaths. She thought that something was odd with Simon after Jolly Otter had a brain aneurysm after his confrontation. She theorised that Simon used the group to fuel his powers. She confronted Simon after he attacked a fascist with his power. Tosh later confronted him about what he had done. Tosh later theorised that Simon was actually a catalyst for Janet's power. Janet asked Tosh to help her to stop Simon. (AUDIO: Instant Karma)

Tosh on Zone 10. (AUDIO: Zone 10)

While working on a time lock in the Hub, Tosh went to Russia as she had cracked the pulse which had come from an object above Russia. She worked with the KVI to investigate Zone 10 and met with its director Maxim Ivanov. She told Maxim that Torchwood was indeed investigating him before his death and wanted to know about Zone 10. She bargained with Maxim to take her there. She thought that the KVI had brought the Committee to Earth. Maxim later worked out Torchwood didn't know that Tosh was in Russia. She worked out that Zone 10 was riddled with time distortions. At the centre of Zone 10 she met with Anna Volokova. When she found out that the FSB agent wanted to kill Anna she devised a plan to escape. She discovered that Anna was kidnapped by the Committee. Maxim told Tosh that Anna was a bargaining chip to stop the war between the Committee and the KVI. She realised that they could use the landing module to escape. Anna told her that Torchwood had been the ones to invite the Committee but Tosh didn't believe her. She was given Object 1 by Anna, who was given it by the Committee. She worked out that the message was created as they both escaped Zone 10. (AUDIO: Zone 10) Tosh managed to reverse engineer the properties of the object in order to make it give good luck. Whilst using it, she stopped a war in Africa just by hearing about it, and went on a date with Owen, who kissed her. Believing that nobody should have that power, she sent it into another dimension and removed her memories of it using retcon. (AUDIO: The Torchwood Archive)

When Gwen revived Suzie Costello with the resurrection gauntlet for questioning, Tosh was unable to look her former teammate in the eye. Instead of keeping her alive for a minute for a brief interrogation, Suzie kept the link between her and Gwen. After Jack's bullets were useless against Suzie, Tosh was ordered to destroy the gauntlet, which killed Suzie and saved Gwen. (TV: They Keep Killing Suzie)

While investigating reports of loud music from the 1940s, the Rift sent Jack and Tosh into 1941. Tosh hid messages that preserved her half of the Rift equations that could get her and Jack home. Owen used these to open up the Rift, bringing Jack and Tosh back to the 21st century. (TV: Captain Jack Harkness)

Owen's actions caused cracks in space and time to spread from the Rift. While cleaning this mess up, Tosh saw an apparition of her mother, telling her to reopen the Rift and undo the damage. The team turned against Jack. Owen shot Jack and reopened the Rift to send everything that had come through back. The opening of the Rift forced out Abaddon, who Jack defeated. (TV: End of Days)

Following Jack's departure, Toshiko was briefly promoted to team leader under Torchwood guidelines as their longest-standing member, but subsequently deferred command to Gwen when she was temporarily rendered mentally unfit to command after exposure to an alien artefact. (PROSE: Kaleidoscope)

Tosh was part of a "wild goose chase" in the Himalayas when Jack went missing. (TV: The Sound of Drums)

While chasing a Blowfish alien through Cardiff, Jack saved a family's life and quickly took over Torchwood again. Torchwood met an old lover of Jack's, Captain John Hart, who had come through the Rift searching for some canisters that had also come through. He told Torchwood that they contained radioactive bombs. Tosh tracked down where each of the canisters were. While searching for one of the canisters with Owen, John wounded them and stole the canister. Ianto recovered Tosh and Owen and Tosh found where Gwen had been poisoned so that she could be treated. They caught up with John, but the contents of the canisters were actually components of a bomb that latched onto the DNA of the owner of the canisters' murderer. Jack and Owen confused the bomb by injecting John with the DNA of the Torchwood team and safely disposed of it. John forcibly left 21st century Cardiff. (TV: Kiss Kiss Bang Bang)

Tosh and Tommy in 1918. (TV: To the Last Man)

During one of Tommy Brockless' yearly awakenings, the past and present time shifts began to occur, which the uniformed thought of as "ghosts". To prevent a temporal catastrophe, Tosh and the team saw to it that Tommy returned to 1918, after the couple had a short sexual relationship. (TV: To the Last Man)

She fell in love with Adam Smith when he gave her memories that they were in love. When she was told the truth, she still couldn't bring herself to take the retcon pill until she realised it was the right thing to do. (TV: Adam)

Owen agrees to a date with Tosh. (TV: Reset)

Toshiko was personally responsible for shutting down the Pharm. By that time she had actually taken the initiative to ask Owen, with whom she had feelings, out on a date. She was extremely saddened when Owen was fatally shot in the chest by Aaron Copley. (TV: Reset) After Owen's return to life via the resurrection gauntlet, she still maintained hope for a relationship, to Owen's disgust given that his currently-deceased status prevented anything sexual from taking place. (TV: A Day in the Death) Later, however, he seemed less negative about the idea. (TV: Something Borrowed)

After Owen brought Torchwood's attention to the Church of the Outsiders, Tosh was tasked with seducing Frank Layton in order to search his house. She forced Owen to listen to her have sex with him as revenge for making her do it. (AUDIO: Believe)

She was contacted by Stephen Heinz a couple of years after the fall of Torchwood One. He booked her on a train to London. He wanted her help with something he found about 27 people disappearing at once. He played her the recording of Nikki. He told her that he was worried that he was next because of his investigation. She used the salvaged Torchwood One technology in Stephen's flat to trace it. She worked out that there was nothing in common between the victims, as they didn't download the same files. She tracked more than one type of this strange occurrence using Stephen's birth date. She tracked it to Max and watched the virus take over him. She worked out that the virus came from multiple torrents. She used the Torchwood servers to download all instances of the virus to try to stop it. The virus took her voice and used her guilt of her brother's death. She saved the virus on her Torchwood profile. (AUDIO: torchwood_cascade_CDRIP.tor)

Toshiko and the rest of the team minus Gwen were investigating an old factory that had detected Rift activity. She was caught up in an explosion of rubble and survived by the help of Gwen but had a broken arm. (TV: Fragments)

Death

Tosh says goodbye to her friends. (TV: Exit Wounds)

Tosh was shot by Gray while communicating via radio with Owen, talking him through his task of preventing a nuclear meltdown at a power station in Cardiff. She talked to Owen about how he would die from the meltdown and they discussed the date they had never gone on. Her wound was fatal and she died in Jack's arms after he arrived back at HQ with Gwen and Ianto. She told them how she had failed to save Owen.

As the team deleted Tosh's profile on the computer system, an automated video message she had recorded played. In it, Tosh thanked Jack for saving her life, and proclaimed her love for Owen and the rest of the team. She reassured them that it was okay that she was gone. (TV: Exit Wounds)

Legacy

Though dead, Tosh's presence was still felt by the others. When faced with certain death at the hands of the Daleks, who were about to overrun the Hub, Gwen expressed her desire to "go out fighting, like Owen, like Tosh"; (TV: The Stolen Earth) she and Ianto were saved by a time-lock defence system that Tosh had been working on before her death. The Hub was sealed in a time bubble, preventing a Dalek from entering to finish them off. (TV: Journey's End)

After witnessing the deaths of a couple in a café who she had been unable to save, Gwen remembered the deaths of Tosh and Owen and how utterly powerless she had felt. (PROSE: Bay of the Dead)

After the 456 incident, Jack revealed that he felt responsible for Tosh's death, along with those of all the other Torchwood operatives who had died under his command. (TV: Children of Earth: Day Five)

The ghost of Ianto Jones' father mentioned Toshiko among the loved ones his son could have seen again if he set Syriath free from the Cardiff Rift. (AUDIO: The House of the Dead)

Whilst leaving Torchwood, Gwen mentioned how she loved Tosh, as well as Owen and Esther Drummond. (AUDIO: Herald of the Dawn)

Alternate timeline

In an alternate timeline in which John Hart took control of the Torchwood Institute and became King of the British Empire, Tosh was likewise a member of Torchwood Cardiff, but died before Gwen Cooper was recruited by the king, who recalled that her death was "very sad, and messy and painful to watch" before agreeing to never speak of it again with Ianto Jones. Nevertheless, Ianto visibly burst into tears as John decided that Gwen would inherit Tosh's desk. (AUDIO: The Death of Captain Jack)

Personality

Tosh considered herself to be a rationalist. (PROSE: Slow Decay) She was a computer genius and arguably the most intelligent member of the Torchwood team. Despite her intelligence, she was insecure and not very confident in her abilities. She didn't like to be studied. She could complete a Rubik's cube within a minute, even when Owen peeled off and replaced several of the stickers. (PROSE: Another Life)

Sebastian Vaughan said that Tosh was spineless and did not listen to her instincts, saying that she was not and never would be Torchwood material. Tosh took notice of this and decided to trust her gut more. (AUDIO: The Vigil)

Tosh was in love with Owen Harper but because of her insecurity, she found it hard to tell him how she felt. (TV: Greeks Bearing Gifts) Tragically, both Tosh and Owen were killed before they could get into a romantic relationship. (TV: Reset, Dead Man Walking, A Day in the Death, Exit Wounds)

Toshiko worried Jack. While she was at the heart of the Torchwood team, she didn't realise it. She felt more remote. Jack suspected that beneath her reserved exterior, there was a supernova of emotion which he didn't want to damage the team. (PROSE: Slow Decay)

Tosh showed interest for men and women, given her continual interest in Owen, and her romance with the female Arcateenian known as Mary. (TV: Greeks Bearing Gifts)

Behind the scenes

Torchwood website

The series 1 version of the Torchwood website had correspondence from Tosh in an unsent draft sent to her aunt discovered by Ianto. It was translated from Japanese into English by Ianto. It said that "for the last week", Tosh was with a woman, referring to Mary, "going from a schoolgirl crush on Owen through to a fantastically fulfilling sex life with a complete stranger". She called it "a week of firsts", including: Tosh's first one night stand, lesbian kiss, lesbian "shag", and the first time Tosh was late to work because of sex.

Other matters

• During her first on-screen appearances, in Aliens of London, Tosh was a pathologist called in to autopsy an "alien pilot". When reintroduced in Torchwood, she was a computer specialist. In her final appearance (Exit Wounds), the character would explain this discrepancy by explaining she was filling in for Owen, pretending to be an MD because Owen had a hangover.
• Tosh left a resounding impression in the Torchwood universe and in the final episode of Children of Earth Jack admits that he feels responsible for her death. It is assumed her body was destroyed when the Hub was blown up by a bomb.
• The name Toshiko means "genius child".
• Toshiko was the only known member of Torchwood Three other than Jack Harkness to have met an incarnation of the Doctor. Gwen and Ianto had spoken to the Tenth Doctor through the Sub-Wave Network during Journey's End, but Tosh was the only one to have physically met an incarnation of him.
