Biography
Family
Martha's parents were France and Clive Jones. She had an older sister, Letitia "Tish" Jones and a younger brother, Leo, who lived with his girlfriend and had a child. On the day that Martha first met the Doctor, her family had a row at her brother Leo's 21st birthday due to Clive insisting on bringing his young girlfriend Annalise, much to his estranged wife's disgust. (DW: Smith and Jones) Martha's cousin, Adeola Oshodi worked at Torchwood 1 before her death (DW: Army of Ghosts).
Joining the Doctor
The twenty-three-year-old Martha was working at Royal Hope when she encountered the Doctor. She encountered him on the street, then gave him a cursory physical (and learnt that he had two hearts) and later helped him defeat the Plasmavore "Florence Finnegan" when Royal Hope was transported to the Moon by the Judoon. She later joined him on his travels. The Doctor insisted, however, that he had not brought Martha aboard the TARDIS as a replacement for his previous companion, Rose Tyler. (DW: Smith and Jones)
After returning home in The Lazurus Experiment, the Doctor allowed her to stay on board the TARDIS. He gave her a mobile phone upgrade and a TARDIS key (DW:42).
Time away from the Doctor
When the Master took over Earth, Martha pretended to make a weapon that would kill the Master. She said that she had witnessed the Toclafane burn the islands of Japan. She spent a year on earth telling everyone to think of the Doctor at a specific time so that the Master could be defeated. This plan worked and the Master was shot by his wife Lucy Saxon. As a result of the destruction of the Master's Paradox Machine, only Martha, her family, and everyone else who was on board the Valiant remembered that year spent with the Master. She decided she wanted to go and complete her medical studies, but gave the Doctor her phone, saying that she might want to return to travelling with him in the future. (DW: Last of the Time Lords)
Joining UNIT and Torchwood 3
The Doctor gave a good word for Martha at UNIT. She was approached by a woman from UNIT who asked her if she wanted to join the organization, and she agreed. As a UNIT agent, she visited Torchwood 3 in Cardiff, where she became embroiled in their investigation of a private medical organization called The Pharm. Torchwood sent her into The Pharm as an undercover agent, but during the course of her investigation she was discovered and captured and the Mayflies were put into her body. Owen Harper saved her life using an alien surgical device but Alan Copley killed him. Just as Copley was about to shoot Martha he was shot in the head by Jack Harkness. (TW: Reset)
Just as she was going to do an autopsy on Owen Harper Jack stopped her. He had found the other resurection glove and used it to ressurect Owen. But also made a "death force" rise from Owen's conscience. This then attacked Martha and she aged to sixty years. The Torchwood team took her to a hospital and where she was told that she was going to die if this force was not destroyed. Owen destroyed it and which reversed the effects. (TW: Dead Man Walking)
Martha was covering for Owen Harper and helped the team for a few days after every thing had happened to Owen. She left Torchwood a few days after and went back to UNIT after Owen Harper was promoted back to Doctor. (TW: A Day in the Death)
Reunion with the Doctor
Martha called the Doctor just as she, together with UNIT, was about to attack the ATMOS factory. The Tardis landed just outside where she made the call and she remet the Doctor and then met Donna Noble. Donna noticed a ring on her finger and Martha told her that she was engaged to Tom Milligan. Martha told the Doctor about ATMOS and introduced him to Colonol Mace who was in charge of the operation. Later that day she warned Donna Noble to keep her family safe because of what had happened to her family the following year. A few minutes later she was told that Colonel Mace wanted to see her but was kidnapped by two solders under Sontaran control and taken to her to a cloning pool, where they started copying her body. She then was put to sleep but kept alive as a her clone was about to aid the Sontarans and needed access to her memories. (DW: The Sontaran Stratagem)
The Clone then went and found the Doctor and went into the UNIT truck as she was doing that Captain Price was launching a Nuclear Strike at the Sontaran ship. The Clone evaded it and stopped it. Later the Valiant came down and started firing at the ATMOS factory destroying some of it but not most of it. The Doctor followed a trace and found Martha a sleep. He woke her up but the clone still had Marthas memories. Marthas clone died soon after having no power. Martha then witnessed Luke Rattigan go into a teleporter and blow the Sontaran ship up. She later was about to part company with the Doctor once more but the TARDIS was pulled away, out of his control. (DW: The Poison Sky)
