Creation and naming (pictured) alongside the co-writer of "Fugitive of the Judoon",
Vinay Patel. The inclusion of the Fugitive Doctor was developed late into the writing process of "
Fugitive of the Judoon", with the script lining up to make her inclusion make sense within the episode. Then-showrunner
Chris Chibnall and co-writer
Vinay Patel developed the idea of the incarnation together, and sought to keep it as much of a secret as possible; the return and on-location shoots of the
Judoon were used to distract fans from the presence of the Fugitive Doctor, which website
Gizmodo framed as "making sure everybody was too distracted to try and piece it together for themselves." The character had no distinct name separate from other incarnations of the Doctor, leading to fans giving her various nicknames, such as the "Ruthless Doctor", a play on the character Ruth's name. The name "Fugitive Doctor", named by fans after her debut episode, eventually stuck as the name of the character, with it being used in an official capacity from the episode "
Once, Upon Time" onwards. Fans also initially theorised that the character was an incarnation from a parallel universe, but Chibnall disconfirmed this, stating that she was "definitively" an incarnation of the Doctor. Though the incarnation does not lead an entire series of her own, Whittaker stated that the Fugitive incarnation was treated like "like any actor taking on the role permanently". Further appearances of the character were not initially planned for
Doctor Who series 13, according to Chibnall, but he said that he would consider it due to how widely popular and accepted the Fugitive Doctor had become within the
Doctor Who fanbase. The character would eventually appear in an episode of the series.
Casting (pictured) portrays the Fugitive Doctor in the character's appearances on-screen.|alt=The Fugitive Doctor is portrayed by actress
Jo Martin. It was not announced prior to the broadcast of the character's first appearance in "Fugitive of the Judoon" that a new Doctor would be debuting. Promotional materials credited Jo Martin only as playing Ruth, while the actress herself was not told that she would be playing the Doctor until she was offered the part after her audition. She was then only able to tell her husband about the character's true identity. Martin had been a fan of the series, having grown up watching
Colin Baker's
portrayal of the character. Martin's incarnation is the series' first on-screen black Doctor, and additionally the first on-screen black and female Doctor. Martin revealed that she was happy the character was able to act as a black role model for young viewers of the series. Following her appearances on-screen, Martin stated she was interested in potentially doing a spin-off following her incarnation of the Doctor, The character is intended to reference earlier incarnations of the Doctor in order to suggest that she is from the
Thirteenth Doctor's past. She declines to use a
sonic screwdriver and refers to the
TARDIS as her "ship", much like the
First Doctor. though an infographic published in the official
Doctor Who Magazine explicitly places her before the
First Doctor and prior to the Doctors seen in
The Brain of Morbius. The interior of her TARDIS is also modelled after the set used in the 1960s, with white walls and an identical central console.
Costume The character's costume was designed by Ray Holman to reflect her sterner nature. Black
combat trousers and boots reference the costume of the Twelfth Doctor, and additionally are meant to indicate the character has experienced combat. She also wears a dark-coloured Scottish
tweed waistcoat and
frock coat, with the tweed being included to reference
Matt Smith's
Eleventh Doctor, who was the first Doctor Holman designed for. The coat is period cut in reference to several "Classic series" (1963–89) Doctors. A brightly coloured
shirt with a stand collar and frilled cuffs are used for their contrasting styles, used to represent the character's eccentric personality traits and were made from African
Kente cloth as a tribute to the actor's heritage and the significance of her casting. This Doctor has also occasionally worn a pair of yellow sunglasses with this outfit. ==Reception==
