Television Freema Agyeman's first appearance in
Doctor Who was in the
second series (2006) episode, "
Army of Ghosts", where she played Adeola Oshodi, Martha's cousin. Martha Jones is introduced in the
third series (2007) of
Doctor Who, first appearing in the episode "
Smith and Jones". When the hospital she works at is teleported to the
Moon, medical student Martha helps save the day alongside an alien time traveller known only as
the Doctor (
David Tennant). To thank her for her help, the Doctor invites her to join him for a supposed single trip in his time machine the
TARDIS, but later accepts her as his full-time "
companion", admitting that she was "never just a passenger", and he even gives her the key to the TARDIS in the episode, "
42". Martha becomes frustrated because the Doctor is oblivious to her feelings for him, and she expresses concern that she is simply a
rebound after the Doctor's painful loss of his previous companion, Rose Tyler. When the amnesiac Doctor falls in love in the two-part story "
Human Nature" and "
The Family of Blood", a pained Martha laments "You had to go and fall in love with a human... and it wasn't me". In the series finale, "
The Sound of Drums" and "
Last of the Time Lords", in which the Doctor's nemesis
the Master (
John Simm) takes over planet Earth, capturing both the Doctor and fellow companion
Captain Jack Harkness (
John Barrowman), Martha manages to escape by teleporting away but is left alone to save the world. On the run from the Master, she spends a year travelling the world in a plan which restores the incapacitated Doctor and reverses time, undoing the Master's actions. Able to remember the events during the Master's reign, Martha then leaves the TARDIS of her own accord, telling the Doctor that she cannot waste her life pining for someone when the relationship cannot happen, but promises that she will see him again. Martha, as voiced by Freema Agyeman, also appears in the 2007 animated serial
The Infinite Quest, which aired in twelve weekly segments during the run of the 2007 series. Martha reappears in the second series (2008) of the
Doctor Who spin-off,
Torchwood, which focuses on Captain Jack Harkness. First appearing in the episode "
Reset" as part of a three-episode
story arc, Martha has been temporarily drafted to the Torchwood Institute|Torchwood organisation of alien-hunters by Jack, requiring a medical expert on alien life. Through exposition, it is revealed that Martha has become a "medical officer" for the international paranormal investigations agency UNIT since qualifying as a
Doctor of Medicine. Martha briefly joins the
Cardiff-based Torchwood Three as its medical officer following the death of
Owen Harper (
Burn Gorman) but later leaves the organisation in the episode "
A Day in the Death" once she is satisfied that Owen is fit to return to duty following his resurrection. Later in the
fourth series of
Doctor Who (2008), Martha returns for a three-episode arc beginning with the two-part story, "
The Sontaran Stratagem" and "
The Poison Sky", and ending with "
The Doctor's Daughter", in which she meets the Doctor's new companion Donna Noble (Catherine Tate); in the first episode, a more assertive and
engaged Martha summons the Doctor to Earth to help uncover a plot by the
Sontarans. Martha returns again for the final two episodes of the series, "
The Stolen Earth" and "
Journey's End", where she has been promoted to a U.S. division of UNIT and is working on a top-secret teleportation project based on Sontaran technology. She rallies alongside fellow companions Jack and
Sarah Jane Smith (
Elisabeth Sladen) in an effort to face the threat of
Davros' (
Julian Bleach) plot to destroy reality. In facing Davros, Martha threatens to set off
nuclear warheads, which will destroy the Earth in order to spare human suffering and curtail his plans, but is stopped by the Doctor. In the episode's
dénouement, Martha leaves with Jack and former companion
Mickey Smith (
Noel Clarke), with Jack saying to her, "I'm not sure about UNIT these days... maybe there's something else you could be doing." Despite the set-up at the end of
Doctor Who series four, Martha does not appear in
Torchwood: Children of Earth (2009). Martha's absence is explained when the characters interact with UNIT officers in
Children of Earth; she is on her honeymoon. In lieu of Martha, the character of
Lois Habiba (
Cush Jumbo) was created. A scene in "
The End of Time" (2010) shows Martha, apparently having left UNIT, fighting aliens with Mickey and marrying him rather than her previous fiancé. The Doctor appears to the pair shortly before his pending
regeneration to save them from a Sontaran sniper. Agyeman is credited as portraying Martha Smith-Jones.
Literature Aside from television appearances, the character of Martha also appears in
Doctor Who novels and comic books, some of which are ambiguous in terms of their
canonicity in relationship to the television series. In books, Martha appears in the "
New Series Adventures" series of
Doctor Who novels, published by
BBC Books. The first book published was a "
Quick Reads" novel,
Made of Steel by
Terrance Dicks (published prior to her first television appearance), and the character subsequently appeared in all novels in the series, starting with
Sting of the Zygons by
Stephen Cole and most recently in
The Many Hands by
Dale Smith. Freema Agyeman physically represents the character on the cover of every novel. In late 2008
The Story of Martha, a collection of stories focusing on Martha's adventures between "The Sound of Drums" and "Last of the Time Lords" was published. In terms of comic book appearances, Martha has appeared in the
Doctor Who Magazine strips from #381 onwards and the
Doctor Who Adventures comics from #28 onwards. The character also periodically appears in the
Battles in Time series of comic books. In 2007, American comic book publisher
IDW Publishing (publisher of various
Angel,
Star Trek and
The Transformers comic titles) announced their plans to do a devoted series of Tenth Doctor and Martha comics for an American audience. When asked about canonicity, IDW executive editor
Chris Ryall dodged the issue by saying all the comics are "blessed" by Russell T Davies but it is up to the individual how canonical each story is.
Audio drama Martha also appears in a
BBC Radio 4 Torchwood drama, "
Lost Souls", which aired in Summer 2008 as an
Afternoon Play featuring the voices of the
Torchwood cast and Freema Agyeman. Set between the events of the 2008 series of
Torchwood but prior to the
Doctor Who finale that year, Martha recruits Jack,
Ianto Jones (
Gareth David-Lloyd) and
Gwen Cooper (
Eve Myles) on Torchwood's first international adventure, as part of Radio 4's special celebration of the
Large Hadron Collider being switched on at
CERN in
Geneva. The special radio episode's plot focuses on the Large Hadron Collider's activation and
the doomsday scenario some predicted it might incite, as well as the Torchwood team's mourning of
Toshiko Sato (
Naoko Mori) and Owen's recent deaths in the
Torchwood second series finale. Martha made her
Big Finish Productions debut in the
Torchwood audio drama "Dissected", released in February 2020. In July 2021, Big Finish announced a new series starring Agyeman -
The Year of Martha Jones - depicting Martha during her year travelling an Earth ruled by
the Master, co-starring
Adjoa Andoh as Martha's mother Francine, which was released in December. ==Characterisation==
