Ace

Dorothy Gale "Ace" McShane was a companion of the Seventh Doctor.

Before travelling with the Doctor
Dorothy Gale McShane was born on 20 August 1970 (PROSE: Timewyrm: Revelation, Falls the Shadow, Set Piece, Relative Dementias) to Audrey Dudman (TV: The Curse of Fenric) and Harry McShane. (AUDIO: The Rapture) She was named after the main character of The Wizard of Oz because her mother (AUDIO: The Settling) and maternal grandmother were fans of the film. Audrey claimed that Ace's grandmother found it took her away from all her miseries. (PROSE: Love and War)

Ace had a younger brother named Liam, who was born in 1974. However, she did not recall her brother's existence until later meeting him in Ibiza as he was taken by their father to live with him after her parents' separation. (AUDIO: The Rapture)

She was a member of the Church of England (AUDIO: Gods and Monsters) but was not very religious. (PROSE: Cat's Cradle: Witch Mark, AUDIO: Fiesta of the Damned))

In February 1971, she was visited as an infant by the Seventh Doctor, who apologise to her for his future manipulation of her at Gabriel Chase and in relation to Fenric. (PROSE: Ace of Hearts)

Ace was a Brownie, one of the lower tiers of Girl Guides. She was kicked out after she turned a summer camp's fairy marquee into a makeshift Molotov cocktail. (PROSE: Survival)

As a child, Ace holidayed in Spain on several occasions. (AUDIO: Fiesta of the Damned)

In the mid 1980s, while working in McDonald's, Ace briefly met the Fifth Doctor's companion Tegan Jovanka. (PROSE: The Crystal Bucephalus)

Naturally aggressive but also clever, Ace was skilled at using her knowledge of chemistry despite failing it for her O-levels, making bombs filled with an explosive of her own devising called Nitro-9. (TV: Dragonfire)

She suffered several traumatic events in her childhood in Perivale, London. These included a bad relationship with her mother, and in 1983 the racist firebombing of her friend Manisha Purkayastha's flat. Manisha died, prompting an angry Ace set fire to Gabriel Chase, an abandoned mansion said to be haunted by an ancient evil. (TV: Ghost Light, PROSE: Blood Heat)

Ace was a troubled teen on Earth, setting off fire alarms at school to miss double French lessons (AUDIO: Revenge of the Swarm) and ultimately being expelled for blowing up the art room as a "creative statement." (TV: Battlefield) She studied The Tale of Beowulf, but only paid attention due to the fighting. (AUDIO: Black and White)

In 1987, at the age of 16, Ace and a friend named Julian Milton planned to run away together, and packed supplies and clothes. (PROSE: Love and War) According to one source, Ace's father had a stroke while she was in Margate with Julian, and he died shortly after she returned. (PROSE: Lucifer Rising)

Later that year, while she was in her room experimenting with the extraction of nitroglycerin from gelignite, a time storm swept her up and transported her to the deck of Sabalom Glitz' spacecraft, the Nosferatu, which was docked at Iceworld in the far future. Trapped on Iceworld, she got a job as a waitress and formed a relationship with Glitz, (TV: Dragonfire) to whom she lost her virginity. (PROSE: Happy Endings)

Some time later, whilst working for Anderson in Iceworld's ice cream parlour, she met the Seventh Doctor, whom she referred to as "Professor", and his companion Melanie Bush, whom Ace nicknamed "Doughnut".

Ace's career as a waitress ended when Stellar's mother complained to Ace about lumps in her milkshake, resulting in Ace pouring the drink over her head and Ace getting fired by Anderson.

When Mel left the Doctor at the conclusion of their battle with Kane, he offered to take Ace with him in the the TARDIS, and she enthusiastically accepted. (TV: Dragonfire)

Early travels
While exploring the TARDIS, Ace found the TARDIS zoo and inadvertently released a dodo. The pursuit lead Ace to a gigantic wardrobe, where she found a mirror reflecting a vampire-like figure. Before the Doctor could explain further, the dodo knocked over the mirror, and the figure vanished. Ace then returned the dodo to the zoo. (PROSE: Echo)

Under the Doctor's tutelage, Ace fought the Daleks and faced Davros in November 1963, destroying one Dalek with an anti-tank rocket and damaging another with a baseball bat upgraded by the Hand of Omega. During this adventure, her portable stereo was destroyed by a Dalek. She also met and came to like Mike Smith. However, she quickly hated him when she found out he was working for the Daleks. (TV: Remembrance of the Daleks). She opposed Helen A and her sadistic government, which required people to be happy on pain of death, and worked with Susan Q to undermine her rule over the colony. (TV: The Happiness Patrol) Visiting the Psychic Circus on Segonax, she helped defeat the Gods of Ragnarok (TV: The Greatest Show in the Galaxy) and stopped the Cybermen from getting hold of the Nemesis statue in 1988. During this encounter, she killed multiple Cybermen with gold coins and destroyed a Cyber-shuttle using Nitro-9. (TV: Silver Nemesis)

At this stage, the relationship between the Doctor and Ace took a darker turn. At least initially, he had been trying to educate her, not merely have adventures with her. His style of teaching, however, was occasionally unorthodox. At times he lied to her, or at least withheld certain truths, so she would face the demons of her past and emerge a stronger person. (TV: Ghost Light, The Curse of Fenric)

She later met Brigadier Lethbridge-Stewart, helping UNIT defeat the Destroyer and Morgaine in Carbury in 1997. (TV: Battlefield)

The Doctor forced Ace to face demons from her past, taking her to Gabriel Chase, arriving a century before she had burnt it down. There, she discovered that the presence in the house of the entity known as Light was what she had felt when compelled to burn the house down. (TV: Ghost Light)

While visiting Maiden's Point in 1943, Ace learned that her arrival on Iceworld was not an accident, but part of a larger scheme conceived by one of the Doctor's greatest enemies, a cosmic evil known as called Fenric. Ace was a Wolf of Fenric, one of many descendants of a Viking tainted with Fenric's genetic instructions to free it from its ancient prison. Fenric had transported her to Iceworld by time storm and made her a pawn in the complex game between it and the Doctor. The Doctor appeared to have been aware of this from their first meeting, although Ace was not. After Fenric was defeated, Ace continued to journey with the Doctor. (TV: The Curse of Fenric)

In another alternate timeline created by, she met the Sixth Doctor and Peri Brown. She gave the Sixth Doctor the nickname of "Joseph," a reference to the musical Joseph and the Amazing Technicolor Dreamcoat. He did not understand the reference, though Peri found it amusing. Although Sixth Doctor did not seem to be particularly pleased at his future self's choice of travelling companion, Ace got along well with Peri, who was surprised to learn that she referred to the Seventh Doctor as "Professor." Ace lost all memory of this encounter when the timeline was erased.

Immediately after this, she and the Doctor visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963. (AUDIO: The Light at the End)

Ace returned to Perivale where she found that most of her old friends had gone missing. She thought they had moved on, but they had been taken to the Cheetah World as prey for the Cheetah People. , an old enemy of the Doctor, was using them to get off the planet. Ace returned with two of her friends and went off to travel with the Doctor again. (TV: Survival)

Adventures with Raine Creevy
As it turned out, the Doctor had been trying to shape her mind to the point that she would be able to attend the Time Lord Academy. His manipulation of her was ultimately for the benefit of Time Lord observers who were assessing her potential. Ultimately, however, she refused this academic opportunity and continued to travel with the Doctor. (AUDIO: Thin Ice) Following this decision, she encountered a young woman named Raine Creevy, with whom she had a somewhat prickly relationship. (AUDIO: Crime of the Century) After leaving her on Earth for a time, (AUDIO: Animal) the trio were reunited onboard the Space Vessel Vancouver. (AUDIO: Earth Aid)

Leaving the Doctor
After both creating and defeating the Timewyrm (PROSE:  Genesys, Timewyrm: Revelation) and restoring the TARDIS after it was damaged in a temporal collision (PROSE: Cat's Cradle: Time's Crucible, Cat's Cradle: Witch Mark) Ace gradually became more and more frustrated with the Doctor's manipulations. (PROSE: Nightshade, AUDIO: Nightshade)

After saying goodbye to her old friend Julian at his funeral, the Doctor brought her and the TARDIS to the planet Heaven in the year 2570. Ace met a young Traveller by the name of Jan Rydd, and fell in love with him. Along with a psychic named Christopher, she helped free the Doctor from being trapped in Puterspace by the Vacuum Church and wanted Jan to travel with her in the TARDIS. However, Jan was infected by Hoothi fibres. Through the Doctor's manipulations, Jan put Ace to sleep with a drug and tried taking a shuttle on his own to the Hoothi sphere, but Máire woke Ace. They followed Jan.

On board the shuttle, Máire betrothed Ace and Jan to be wed. Thinking that they would set the shuttle on a collision course with the sphere, Ace and Máire ejected their pods. Jan instead ignited the sphere with his pyrokinesis, killing three of the four Hoothi and sacrificing himself.

Landing on Heaven, Ace spoke to the part of the Hoothi group mind containing Julian, killing the last Hoothi and freeing the dead minds from the group mind. Angered by him causing Jan's death, Ace left the Doctor. (PROSE: Love and War, AUDIO: Love and War)

In Spacefleet
Now living in the 26th century, Ace joined Spacefleet and fought Daleks and other intergalactic threats. She encountered Bombardier Daleks and tried to steal the power from a Special Weapons Dalek after it vaporised a Red Crescent ship full of children, pitying it as it begged her to kill it. (PROSE: Lucifer Rising) She also spent three weeks in a mine on a nameless alien world, was chased by a creature with six arms, (PROSE: Falls the Shadow) took part in the Ramos Offensive on Lan Beta and was stationed on Verdanna. (PROSE: Parasite)

Three years later, combat-hardened and cynical, she rejoined the Doctor and Bernice Summerfield, (PROSE: Deceit) attempting to gather information for IMC. (PROSE: Lucifer Rising)

Travels with Bernice Summerfield
Ace's relationship with Bernice was at first less than cordial, possibly out of jealousy, but the two eventually became friends. While in 1976 London, with her relationships with Bernice and the Doctor at breaking point, Ace accepted the offer of the misguided renegade Time Lord to join with him as his companion and accomplice. However, she meant to betray Mortimus all along. By this time she had finally gotten over the death of Jan, and was finally able to reconcile with the Doctor and Bernice. (PROSE: No Future)

The Doctor, Benny and Ace visited the Pinehill Crest Hotel in 2003. She was tasked in investigating a Time Experiment. She pretended to hate the Doctor when the Scourge invaded and watched what they did to the humans. She asked Michael Pembroke to deafen her in order that she wouldn't get controlled by the scourge. She made her way to the TARDIS on the Doctor's orders and once she entered she started to hear. The Doctor asked her mess about with the dimensions. (AUDIO: The Shadow of the Scourge)

When she accompanied the Doctor to Orbos to collect Benny, she was affected by Remnex's psychic message. She then helped Benny do her work, before she heard Remnex's scream. She was stunned by Slyde but later recovered. The Doctor later entrusted her with the safe keeping of the skull of Vilus Krull, whilst he went to Marran Alpha. She later found out that both Slyde and Lomar were part of the Cult of the Dark Flame. After being trapped on Marran Alpha she had to fight the living skeleton's before the Doctor got them back to the Space Station. The Doctor later asked her to pull a lever to stop a black light explosion. (AUDIO: The Dark Flame)

After their ordeal with the Robot Ants, Ace left the Doctor again to become Time's Vigilante.

(PROSE: Lungbarrow)

Ace was eventually admitted to the Time Lord Academy on Gallifrey, where she was given the planet of Talmeson to watch over. Visiting Earth to catch up with her mother, she discovered that she had died from cancer. When she returned, she discovered that Talmeson had been wiped out by the Daleks, prompting her to wipe them out by time locking Skaro with an Omega device. When the Doctor found out that Ace had gone missing, he sent Benay to find her. (AUDIO: The Lights of Skaro)

Ace later saved Benny from the being trapped in a pyramid on Mars. (AUDIO: The Pyramid of Sutekh) Taking her to find the Eye of Horus for the Doctor, the pair found that it wasn't in Sutekh's tomb. She used her thieving skills to try and steal it from a museum, but discovered that it was already stolen. Ace and Benny tracked it down to Graull's bank where they used it to release Isis. (AUDIO: The Vaults of Osiris)

Rejoining the Doctor in his TARDIS, she was sent by him to follow Harmonious 14 Zink to Erratoon and was imprisoned with a nameless Tracer who had taken human form. There, her memory was wiped by the robotic constables, but she was rescued by the Doctor, who planned to restore her memory with the help of the TARDIS. (AUDIO: The Prisoner's Dilemma)

When Ace and the Doctor investigated Sherilyn Harper as she had the Fearmonger inside her, she used her wits and ingenuity to talk to Walter Jacobs to get him on their side.

When she found the painting she was mentally attacked by it. They also encountered the Master who wanted to use the planet animated by the Warp Core as a weapon against the universe. (AUDIO: Dust Breeding)

They landed in Colditz Castle in October 1944, where the Doctor was shot and she became a prisoner of war. Her rucksack was searched and Kurtz took her walk-man.

James Dean and Ace started dating and Ace got a tattoo with "ACE, JIMMY, LONDON 1959" written in ribbons over a heart. She later even became pregnant with James Dean's child, but Ace was killed by George Limb and their child never came to life. When James found out about his unborn child he stopped supporting George Limb and travelled back through time. He died in the car crash as he was destined to do. Due to the temporal disruptions caused by Limb's attempts to use a flawed time machine he'd acquired from the Cybermen, the Doctor was "reunited" with a version of Ace from a timeline slightly divergent to the one he'd experienced, as various realities collapsed together to cope with the damage caused by Limb's actions. This version of Ace didn't have a tattoo, disliked peas and had trouble remembering her correct surname, but was otherwise identical to the "original". (PROSE: Loving the Alien)

Adventures with Hex
Whilst in London in 2021 investigating with the Doctor for evidence of "xenotech" — alien technology being used on humans, which was in fact Cyber-Technology — she met Hex, a nurse working at St Gart's Hospital.

Upon entering the Black TARDIS, however, they discovered Sally Morgan and Lysandra Aristedes already there. (AUDIO: Protect and Survive)

Upon discovering this, they realised that the Doctor was travelling in two separate TARDISes, simultaneously.

(AUDIO: Signs and Wonders)

As a CIA agent
She eventually returned to Gallifrey and completed her Academy training, and joined the Celestial Intervention Agency. She undertook many missions for them, often to avert civilisations from discovering time travel, but was annoyed that her TARDIS had a working chameleon circuit, making it difficult to find in the field, and wished it could just appear to be an old police box.

On one such mission, she arrived back at her TARDIS to find Rexx, a Time Lord who wanted to give her a mission as her companion to discover origin of an anomaly near Earth. Rexx took her to the site of the anomaly and found the Hand of Omega there. Rexx thought that Ace couldn't be trusted as she was loyal to Romana. He used Ace as Romana had given her certain privalages since she had travelled with the Doctor and had her hypnotised as she had affinity with the Hand due to a previous adventure with the Doctor. He planed to then have Omega inhabit her in a bid to help him escape. Coordinator Narvin was sent by Lady President Romana to find her and tracked her to Greater Henge on Earth before they were both taken through the black hole into Omega's domain. When they arrived, Omega released his control on Ace. When Romana arrived in this domain she enabled Ace to help stop the realm collapsing. Omega stole her TARDIS, because it was known to the CIA. She escaped from the domain, with Romana and Narvin piloting the Type 160 but when it ran out of power she was stranded just after escaping the black hole with Narvin after Romana was saved by Irving Braxiatel. (AUDIO: Intervention Earth)

She was charged with treason, and Trave was sentenced to execute her due to Ace's part in the Omega Plot. After the timelines had be changed, Romana now as Coordinator of the Celestial Intervention Agency sent her to Outpost Delta, on the boarder of Monan Host and Gallifreyan space. She also took delight in imprisoning Adjutant Coordinator Tauras. She used her explosive expertise to disarm a bomb on the station. After disposing of the bomb, she was attacked by The Watchmaker. When Romana made a deal with the Watchmaker and the timelines were rewritten again, she did not die. (AUDIO: Enemy Lines)

At some point during her time on Gallifrey she was tasked in alerting the Doctor and Raine Creevy that had stolen the Dimensional nodes from the vault on Tersurus. Due the energy drain at the Doctor's location she couldn't get the full message out. (AUDIO: Dominion)

Alternate fates
Ace, still apparently a teenager and accompanying the Seventh Doctor, died in an explosion she set to kill one of the three Lobri. (COMIC: Ground Zero)

Alternative timelines
In an alternative timeline, Ace was killed by Chad Boyle in December 1978 when he hit her on the head with a brick. Boyle was subsequently recruited by the Timewyrm. This timeline was negated when the adult Ace prevented Boyle from attacking her younger self. (PROSE: Timewyrm: Revelation)

In another alternative timeline, Ace was killed by Kurtz in Colditz Castle in October 1944. The laser technology contained in her Walkman was used by Nazi scientists to refine uranium and create nuclear weapons. They subsequently bombed New York City and Moscow, forcing the surrender of the United States and the Soviet Union and winning the war for Germany. This timeline was negated by an alternative version of the Eighth Doctor who, while posing as a German scientist named Johann Schmidt, fabricated a "flight log" for the TARDIS and manipulated Elizabeth Klein into travelling back in time to Colditz in October 1944 on the pretext of retrieving the Doctor so that he could teach her to pilot the TARDIS. Her lover Major Jonas Faber saw through Schmidt's trickery but was too late as Klein had already decided to disobey his orders and make the trip into the past. Unfortunately for Klein, her arrival in Colditz alerted the Seventh Doctor to the impending alteration of history and he and Ace were able to prevent it. (AUDIO: Colditz, Klein's Story)

In an alternate timeline where the computer was never invented, it was strongly implied that Ace became a young woman known as Dee, who worked with the amnesic Eighth Doctor to try and topple the corrupt Star Chamber that ruled Britain. (PROSE: The Domino Effect)

In another alternate timeline created by, she met the Sixth Doctor and Peri Brown. She gave the Sixth Doctor the nickname of "Joseph," a reference to the musical Joseph and the Amazing Technicolor Dreamcoat. He did not understand the reference, though Peri found it amusing. The Sixth Doctor did not seem to be particularly pleased at his future self's choice of travelling companion. Ace got along well with Peri, who was surprised to learn that she referred to the Seventh Doctor as "Professor." Ace lost all memory of this encounter when the proper timeline was restored. (AUDIO: The Light at the End)

When the Cybermen allied with Rassilon to take over history, Ace was cyber-converted and confronted the Seventh Doctor while he was planting Nemesis mines across the Cyber-Fleet. (COMIC: Prologue: the Seventh Doctor)

Undated events

 * At some point, Ace was taken to the Black Archive by UNIT to have her record as a companion of the Doctor taken. Her memories of the visit were subsequently erased and she was sent on her way. (TV: The Day of the Doctor)

Personality
Ace covered her fears and insecurities with a tough, streetwise exterior. Her weapon of choice, disapproved of by the Doctor (who nonetheless found it useful on occasion), was a powerful explosive she called "Nitro-9", which she mixed up in canisters and carried in her backpack. She also wielded a baseball bat.

She was convinced the Doctor needed her to watch his back and was fiercely loyal to him. (TV: The Curse of Fenric) In turn, the Doctor took a special interest in Ace's education, taking her across the universe and prompting her to come to her own conclusions rather than giving her all the answers. (TV: Ghost Light)

She believed that the Doctor had the "deepest, saddest eyes." (AUDIO: The Prisoner's Dilemma)

Ace once told the Doctor that she loved him. (AUDIO: Signs and Wonders)

She did not want to have children. (AUDIO: Signs and Wonders)

The Doctor expressed a belief that she would either become a renegade Time Lord or Lord President of the High Council. (AUDIO: The Lights of Skaro)

Ace gave Mel the nickname "Donut". (TV: Dragonfire; AUDIO: A Life of Crime, Fiesta of the Damned)

Ace once described the Doctor as her guru. (AUDIO: Nightshade)

Ace's name
Ace's full name was never revealed on the television series, in which she was usually referred to by her nickname. Her surname was not established until original novels featuring the character were published, but her first name, Dorothy, was referred to on screen in the television story Dragonfire.

Production notes suggest that it was intended that her last name would be Gale, given the fact that she was transported to Iceworld via a time storm, much like Dorothy Gale, transported to Oz by a tornado in The Wonderful Wizard of Oz. The novels (and, later, the Big Finish audio dramas) gave Ace the last name of McShane. The Past Doctor Adventures set after the television story Survival and written by Mike Tucker and Robert Perry used the surname Gale, as the authors were unaware of the name used in the New Adventures. This was eventually resolved to some extent when the novel Relative Dementias by Mark Michalowski gave her full name as Dorothy Gale McShane, a version later taken up by the audios.

Ace's farewell
Ace is the only televised companion whose departure from the Doctor's company has not been definitively established in any media. Instead there are a number of conflicting accounts.

If Doctor Who had continued as a television series after Season 26, Script Editor Andrew Cartmel had planned that Ace go to attend university on Gallifrey where, despite her human heritage, she would have trained as an apprentice Time Lord. She would have left halfway through Season 27.

Beginning with the novelisation of The Curse of Fenric, spin-off media have put forward conflicting scenarios of how Ace finally departed the company of the Doctor. The TV movie Doctor Who did not explain or rationalise her absence.

In The Sarah Jane Adventures television story Death of the Doctor, a reference was made to a former companion of the Doctor named "Dorothy", who was running an organisation known as "A Charitable Earth". Sophie Aldred has stated that she does not believe that this would be Ace's chosen profession, unless the charity was nothing more than a front for UNIT.

Russell T Davies revealed in issue 445 of Doctor Who Magazine that he hoped to have Aldred return as Ace in The Sarah Jane Adventures, both in the present day and potentially also in flashback sequences. The death of Elisabeth Sladen, however, prompted the premature conclusion of the series.

Miscellany

 * Ace was the last companion of the Doctor to be a minor, up until Courtney Woods, who was 15. Ace was 16 when she joined the Doctor.
 * According to Rona Munro, the writer of Survival, there was to be a lesbian subtext to the relationship between Ace and Karra. This raises the possibility of Ace being the first LGBT companion on screen. (DOC: Cat-Flap)
 * Ace was voiced in the German dub by Carin C. Tietze.
