Captain Jack Harkness (sometimes simply "Captain Jack" to those close to him), was the name adopted by a con man from the 51st century and an associate of the Doctor. His original identity remains a mystery. Reluctantly immortal and stranded on early 21st century Earth, he headed Torchwood 3.
Biography
- Given his frequent time travelling, much of Jack's personal chronology remains confused. However, we can say with some certainty that certain events happened to Jack before he met the Doctor, and others afterwards. However, we cannot necessarily regard everything Jack says as accurate.
Youth
Jack was brought up on the Boeshane Peninsula, in a sandy beach-like area. He often played with his brother Gray and his father. They played cricket and sang around campfires. Then one day an alien race invaded his homeland and killed many of the inhabitants. Jack was told by his father to run away with Gray while he went back for Jack's mother. Jack accidentally let go of Gray's hand while running. He returned to his home hoping to find him, but all he found was his dead father. Jack claims it was the worst day of his life. He spent many years searching for his brother, but never found him. (TW: Adam)
Escapades
Originally, Jack used a different name, though we do not know what it was. (TW: Captain Jack Harkness). He grew up sometime around the year 5000, an era differing attitudes to sex to those prevalent in the 21st century. Humans had begun to expand outwards to explore the universe, and, meeting other species, often pursued sexual relationships with them, regardless of differences of gender or species. (DW: The Doctor Dances) Although human stereotypes of "bisexuality" and "homosexuality" have been applied to Jack (i.e. Owen Harper once indicated to Gwen Cooper that Jack was "gay" (TW: Day One)), correctly Jack cannot be referred to by either of those terms.
As a young man, he persuaded a friend to "join up" with them to fight against some unspecified enemies that Jack did not describe or name — other than to call them "horrible", though it seems plausible that they are the same race that invaded Jack's home. Considering Jack's friend to be the weaker of the pair, the enemies tortured him as a lesson for Jack. Jack bore the guilt of his friend's fate. (TW: Captain Jack Harkness)
Once, when sentenced to death, he ordered four hypervodkas as a last meal and ended up bedding both executioners (at the same time). (DW: The Doctor Dances)
He also had a memorable experience once on a hunting expedition. (DW: Boom Town)
As a Time Agent
Jack Harkness worked as a Time Agent until he discovered that the Agency had erased two years of his memory, two years he wanted to have back. (DW:The Empty Child)
He had a friend called John Hart who also worked as a time agent. At some point, he spent five years trapped in a two-week time loop with John Hart, with the two becoming the equivalent of a married couple after spending so much time together (Hart eventually conceded that he was "a good wife", which closed the argument about which of them was the wife). (TW: Kiss Kiss, Bang Bang)
As a Con Man
Having left the Time Agency, Jack become a time-travelling con artist, performing various scams using his knowledge of future events, such as demanding money for items that he knew would be destroyed before the buyer could see it. He assumed the alias of an American volunteer Captain Jack Harkness, serving as a volunteer in the 133 Squadron of the Royal Air Force. (DW: The Empty Child)
The "real" Jack Harkness had died in action in January 1941. The impostor knew very little about the "real" Jack, other than basic information, such as the former's date and manner of death. (TW: Captain Jack Harkness)
Prior to February 1944, he met Estelle Cole. (torchwood.org.uk) The pair spent some time in London together. She wanted to spend the rest of her life with him. Somehow, however, this never happened, and they lost touch with one another. (TW: Small Worlds)
- This may have happened after meeting the Doctor as he teleported back to 1869, although it seems unlikely as he was working for Torchwood at the time.
Travels with the Doctor
First meeting with the Doctor
Jack worked as a con man, finding pieces of space junk and directing them to soon-to-be disaster sites, selling them to passers by, and letting them get destroyed before the buyers could pick up their merchandise. He would, at some point, acquire a sleek, small Chula spacecraft, fitted for human use, which could turn invisible.
In 1941, while pulling a con with a Chula Ambulance during the London Blitz, he spotted Rose Tyler hanging from a barrage balloon and rescued her, taking her aboard his Chula ship. Quickly finding out Rose came from the future, he suspected that other Time Agents had discovered him. (DW: The Empty Child). Shortly after, Rose introduced him to the Ninth Doctor. Together, the trio worked to stop the Empty Child plague brought about by the Ambulance's nanogenes. Although he was almost killed carrying in his ship a German bomb about to explode, the Doctor and Rose rescued him just before the ship exploded. (DW: The Doctor Dances) He accompanied them on their subsequent adventures.
Abandonment
Jack was aboard Satellite 5 when the Dalek fleet launched their assault on Earth and was exterminated while defending the satellite from their advance. He was resurrected by Rose Tyler, who at that time had the powers of the Time Vortex which turned her into the Bad Wolf. Returned to life, Jack discovered he was now immortal, although he was unable to rejoin the Doctor and Rose before the Doctor's TARDIS departed, and was left stranded on the satellite. (DW: The Parting of the Ways) The Doctor, who had just regenerated, believed that Jack could begin the process of "rebuilding the Earth". The Doctor's instincts told him to run because from this point on Jack became a "fixed point" in time. (DW: Children in Need Special)
Life on Earth
Arrival in the 19th century
After Jack was left on Satellite 5, he employed the Vortex Manipulator in his Time Agency wrist strap to go back to Cardiff, the location of an active space-time rift. Unfortunately, Jack ended up in 1869. (DW: Utopia)
- Coincidentally or not, the Doctor had first encountered the Cardiff rift in that year. (DW: The Unquiet Dead):
Jack's second death and resurrection occurred when he was shot in 1892 during a fight on Ellis Island. (DW: Utopia) Jack would find that he still aged, but very slowly, could recover from any injury and from death itself, given a few minutes time. (DW: Last of the Time Lords)
At some point he joined a traveling show and was billed as "the man who couldn't die" in order to investigate the Night Travellers. (TW: From out of the Rain)
He hung around the city, knowing that the TARDIS could re-fuel itself using the rift and that the Doctor would one day return there. (TW: Fragments) Established in 1885 (TWN: Slow Decay), Torchwood Cardiff (later Torchwood 3) monitored the space-time rift located in the city. In 1899, Torchwood Cardiff agents Alice Guppy and Emily Holroyd found out about Jack's immortality and about the Doctor. They captured Jack and tortured him trying to discover why he couldn't die and what connection he had to Torchwood's enemy, the Doctor, who Jack had mentioned in conversation. He was released on the condition that he worked for them. On his first mission he had to go stop a criminal Blowfish, which he returned to the Hub only to see it killed by a shot to the head. He refused to do any more missions, but found himself persuaded to take them up their offer. (TW: Fragments)
20th century
He continued working for Torchwood for about a hundred years, still pursuing his attempt to find the Doctor in the meantime. (TW: Fragments)
- Whether Jack fought in World War I during this time, or whether he had already remains unknown, though he did seem absent from Gerald Carter's Torchwood 3 during that time. Jack's long involvement with Torchwood overlaps the Doctor's involvement with UNIT, supporting the notion that Jack may have played a role in Torchwood not becoming involved in the Doctor's UNIT exploits; this is supported by his comment in Utopia about waiting for the right incarnation of the Doctor to come along, suggesting observation of earlier incarnations.
Jack became leader on New Year's Day 2000 when the then-current leader, Alex Hopkins, knowing Jack couldn't die, shot to the death the rest of the team, before committing suicide himself. That left Jack as Torchwood 3's leader and only member. (TW: Fragments)
21st century
Recruitment of the new team
Jack recruited Toshiko Sato in either 2003 (TW: Fragments) or 2005 (TW:Greeks Bearing Gifts), and Owen Harper was recruited approximately a fortnight before the events of Aliens of London (TW:Fragments). At some stage, Suzie Costello, his second-in-command joined the team. (TW: Fragments).
Jack's activities at the time of the Blaidd Drwg incident in Cardiff - which involved Jack's younger, non-immortal self - are unknown, even though it is known that he was in charge of Torchwood 3 and based mere feet from the TARDIS' arrival at the time. (DW: Boom Town)
After the destruction of Torchwood 1 in the Battle of Canary Wharf, Jack still continued to run Torchwood 3. With Torchwood 1 gone and Torchwood 4 having "gotten lost", Jack ran Torchwood 3 with more or less complete freedom and decided to run it according to the ideals he thought the Doctor represented. (DW: The Sound of Drums) In 2007, following the destruction of Torchwood 1 in the Battle of Canary Wharf, he took in Ianto Jones, after some heavy persuasion by Ianto himself. (TW: Fragments)
Jack, though, held on to the hope of re-establishing contact with the Doctor, whom he believed could help him. He kept the Doctor's hand (which he had lost, but re-grown on Christmas Day, 2006) in a portable hyperbaric chamber in Torchwood 3's nerve center, the Hub. (TW: Everything Changes-TW: End of Days)
Lastly, after his second-in-command Suzie Costello got exposed as a serial murderer and shot herself, he took in Police Constable Gwen Cooper (TW: Everything Changes)
He revealed very little of himself or his origins to his team, even when pursuing a flirtatious relationship with Gwen Cooper (TW: Ghost Machine) and a more physical one with Ianto Jones. (TW: They Keep Killing Suzie) Although he rarely confided in his team, preferring to keep his past secret- Gwen was the first person to learn about his immortality-, he nevertheless often showed great compassion for them and other innocents who got caught up in Torchwood's missions (TW: Out of Time), even as he demonstrated a far more ruthless side in dispatching the team's enemies than the Doctor might have exercised (TW: Countrycide). Transported back to 1941 by the Cardiff rift, Jack met his namesake, the original Jack Harkness, and briefly romanced him, before returning to the 21st century. (TW: Captain Jack Harkness)
After the Cardiff rift was finally opened by Owen Harper, Jack was forced to confront Abaddon, released from the rift by Bilis Manger. Abbadon was destroyed while attempting to leech Jack's life, though the exertion Jack remained dead for three days, his immortality apparently unable to save him. He was brought back to life by a kiss from Gwen. (TW: End of Days) Minutes after his resurrection, Jack noticed the Doctor's hand begin to glow. The sound of the TARDIS materialising was heard inside the Hub. By the time the rest of the Torchwood team arrived to investigate the sound, Jack had gone. (TW: End of Days)
Reunion with the Doctor
Seeing the TARDIS, he grabbed on to the outside as it was dematerialising. The TARDIS tried to shake him off, throwing the Doctor, Martha Jones and Jack into the year 100 trillion. (DW: Utopia)
When he arrived in the year 100 trillion, he appeared dead, but, just as Martha was attempting to revive him, he awoke, gasping for breath. Jack, The Doctor and Martha saw a man being chased by the Futurekind. They went to a base where the last humans were hiding from the Futurekind. He brought the Doctor's Hand with him, describing it as a 'Doctor detector', and he met the Professor Yana. Jack helped to launch the ship by entering a chamber flooded with Stet radiation, and fixing the power canisters (the radiation would have killed a normal human). When Yana was discovered to be The Master, he took the Doctor's hand and went back in time to the 21st century. Jack, the Doctor and Martha returned to the 21st century using his Vortex Manipulator to escape from the Futurekind. He revealed to the Doctor that he was recruited in Torchwood 3 when he returned to Earth following the Battle of the Game Station. The Doctor was appalled at this; Jack stated that the old Torchwood had been destroyed at Canary Wharf. After the battle had ended, he had taken over and rebuilt Torchwood anew, in the Doctor's name. Soon after this explanation, Jack was arrested onboard the Valiant by Mr. Saxon, (the Master) along with the Doctor and Martha. After being imprisoned within the Valiant for one year, he managed to release himself (perhaps with the help of the Doctors temporary superpowers) and destroyed the Master's Paradox Machine.
Coming back to Torchwood 3
After being onboard the Valiant with The Doctor and The Master for a year of an erased time line, Jack returned to Torchwood and the Team. Surprisingly for the Team, Jack arrives just in the nick of time to save a woman's life by killing a blowfish-like alien. The Team wondered where he had been, although he refused to explain himself, besides making a reference to his previous adventure with The Doctor. While this took place, there was some Rift activity and his old friend Captain John Hart from the Time Agency appeared in Cardiff. Jack tracked him to a bar, where they reunited with a passionate kiss, followed by a lengthy bar brawl. Soon after they got talking about their past lives. He told Jack that there were three alien 'radiation bombs' nearby, and the team split up and searched for them. Captain John was teamed up with Gwen. Hart disabled the team one-by-one after conning them into finding the pieces, which formed a triangular ring, to slot around a pyramid hologram device being carried by the blowfish alien. John Harts ex-girlfriend appeared in the hologram, and claimed that the device would attach a DNA-seeking high-explosive onto whoever killed her. Hart subsequently handcuffed himself to Gwen with deadlock sealed cuffs and he raced to the rift, while Jack and Owen concocted a means of confusing the bombs DNA scanner, arriving just in time to save Harts life, throwing the bomb into the rift. The resultant explosion caused all of the events prior to Hart's arrival to reset to before he arrived. Hart asked for a place on the team but Jack callously declined, telling him to leave. As Hart faded through the rift he mentioned to Jack that he knew where Gray was. A shocked Jack claims that the statement meant nothing. (TW: Kiss Kiss, Bang Bang)
After Jack met Martha Jones when fighting the Master, he invited her onto the team for a few days. He asked her to investigate the Pharm, a medical organization that could cure diseases that were incurable. He ordered Toshiko to close it down. But the Pharm manager shot Owen Harper and then Jack shot him. Martha stayed for a few more days and he put her in charge as Medical officer. (TW: Reset) Jack found the other resurrection glove and resurrected Owen Harper. It worked but Jack had released an extradimensional alien, the embodiment of death, Durac. Owen saved the day by not giving his soul to Death and survived. (TW: Dead Man Walking)
Jack met his younger brother Gray again when John Hart came back and bombed a warehouse to kill all members of the Torchwood 3 team. This failed and Jack found a message from John on his Vortex Manipulator. Only to find that Gray and him were going to blow up Cardiff. (TW: Fragments) Jack discovered John was being manipulated by Gray who had him molecularly bonded to an explosive device, vengefully forcing John to bury Jack in the land that would become Cardiff in AD 27. Gray, insane, had blamed Jack for the unspeakable tortures he underwent in his capture, and wanted Jack to experience a similar neverending pain. Stuck in a cycle of death and resurrection, Jack is discovered by Alice Guppy and Charles Gaskell of the Torchwood of 1901, who he demands cryopreserve him until the present day. Jack awakes again to encounter Gray, forgiving him of his trespasses despite Gray's own unwillingness to absolve Jack. Jack chloroforms and cryopreserves Gray, refusing to kill him, but the damage had already been done, as Gray had been responsible for the deaths of Owen Harper and Toshiko Sato. Jack and John part ways on better terms, with John travelling the world in the 21st century and Torchwood Three reduced to Jack, Ianto and Gwen. {TW: Exit Wounds)
The Medusa Cascade
An undisclosed amount of time later, the Earth was relocated by the Daleks to the Medusa Cascade. Initially, Jack was powerless to do anything but listen to the threatening Dalek communications and await the inevitable extermination of his friends (if not himself). Soon, however, he found himself involved in a secret communications network involving former prime minister Harriet Jones, Martha Jones, and, ultimately, Donna Noble and the Doctor. After getting vital information from Martha that allowed him to reactivate his vortex manipulator, Jack teleported near to where the Doctor and Rose Tyler's reunion was interrupted by the Doctor being shot by a Dalek. (DW: The Stolen Earth) Subsequently, after the Doctor's regeneration aborted, Jack boarded The Crucible and surrendered to the Dalek forces. In order to infiltrate the vessel, he attempted to shoot the Supreme Dalek and was "exterminated". He subsequently burrowed into the Crucible and linked up with Sarah Jane Smith (to whom he expressed admiration), Mickey Smith and Jackie Tyler. Using Sarah Jane's Warp star, he attempted to bluff the Daleks into calling off the detonation of the reality bomb but was ultimately transported to Davros' chamber instead. Later, after the Daleks were defeated by the "DoctorDonna", he helped pilot the TARDIS as it returned the Earth to its original location. Afterwards, he was last seen offering Martha Jones a position with Torchwood, and soon after was joined by Mickey - but not before the Doctor re-deactivated his vortex manipulator. (DW: Journey's End)
Possible futures and Alternate realities
Future as the Face of Boe?
Jack has mentioned that in his childhood home, the Boeshane Peninsula, as result of being the first one ever (whether of the Peninsula or of the Time Agency generally remains unclear) he had been a poster boy and so was nicknamed the Face of Boe. (DW: Last of the Time Lords) Jack had previously mentioned that he did know of the "real" Face of Boe. (TDA: The Stealers of Dreams)
Whether this would make Jack the actual future Face of Boe remains unknown. This would explain how the Face of Boe had foreknowledge of the Doctor and of the true identity of Professor Yana. If Jack does become the Face of Boe, then he is destined to die in the year 5,000,000,053 (DW: Gridlock). However if Jack's existence, as he was in Parting of the Ways, indeed has been fixed in time then he could not die at all (the Doctor seemed to believe this to be case as he suggested Jack might find himself in the shelter on Malcassairo), and thus he could not be the Face of Boe, however, Jack's ressurections can be delayed under unique circumstances, such as giving his lifeforce to feed Abaddon to death suggesting that if Boe is indeed Jack then he may not have truly died. The reason is that The Face of Boe in Gridlock had been giving his lifeforce for a solid 53 years, which would mean that Boe could be "dead" for years before he revives. Another theory is that Jack can only die of old age, as that appears to be the only method he has not experienced. It is also possible that the Doctor mistook "impossible to permanently kill under nearly all circumstances" with "immortal," as the two might "feel" the same to the Doctor's time sense.
Another indication of Boe being seperate from future incarnations of Jack Harkness is Boe's supposed age. It is stated the he has existed since the Dark Ages, suggesting that in the future Jack is somehow lost or willingly travels into the past and evolves into Boe.
Donna's World
If Donna Noble had turned right, instead of left, stopping herself from ever meeting and saving the Doctor. Jack would have lost fellow Torchwood members, Gwen Cooper and Ianto Jones, who sacrificed their lives to save the Earth from the Sontarans' plan involving Atmos and would have been transported to Sontar, the Sontaran homeworld. (DW: Turn Left). The fate of this version of Jack is unknown.
Special items
When Rose and the Doctor first met him, Jack owned a own small Chula Warship, fitted for human use, as well as psychic paper and a store of nanogenes in the ship. When saving the Doctor and Rose by carrying a German bomb a safe distance away from London, the bomb explodes inside the ship, but luckily, the Doctor and Rose saved him. (DW: The Empty Child, The Doctor Dances)
Other information
Weapons
Jack owned a sonic blaster in the Doctor Who episode, 'The Doctor Dances'. (DW: The Doctor Dances) He also managed to store a Compact Laser Deluxe away somewhere "you really don't wanna know"', in case of emergencies. (DW: Bad Wolf). During his travels with the Doctor, he modified the Defabricator, to be capable of destroying a Dalek. (DW: The Parting of the Ways) As the leader of Torchwood 3, Jack liked to carry a World War II Webley. (TW: Everything Changes onward).
Special abilities
Since his resurrection by the Bad Wolf entity (DW: The Parting of the Ways), Jack can "die" and come back to life almost instantly (TW: Everything Changes onwards). So far he has "died" of a gunshot to the head (TW: Everything Changes, TW: End of Days) and multiple electrocutions (TW: Cyberwoman). In some circumstances, such as when in a scrape with a Weevil (TW: Combat) or pterodactyl (TW: Fragments), Jack heals of all wounds incurred instantly, but he does not necessarily heal from such minor injuries as a bloody lip (TW: Cyberwoman). Jack's confrontation with Abaddon forced him as close he could come to true death. (TW: End of Days) Jack views this power as a curse as much as a blessing, as each time he has died he has not experienced anything at all, good or bad, (TW: Everything Changes) although the process of resurrection is described as like being "hauled over broken glass" (TW: Kiss Kiss, Bang Bang).
Like other men in the 51st century, Jack possesses evolved human pheromones which make him naturally nice-smelling and attractive to others. (TW: Fragments)
Tosh could not use Mary's telepathy pendant to read his thoughts, although he could project thoughts to Tosh if he so chose, apparently showcasing some kind of psychic defence. (TW: Greeks Bearing Gifts)
- It may be that he expanded his psychic ability after he transformed or that his larger brain size and different physiology made his ability more powerful.
Unrecorded adventures
- Jack once quipped about the time he got pregnant, a memorable experience, though not necessarily in a good way. (TW: Everything Changes)
- Although he states at the time that he is never going to become pregnant again, reference to the Face of Boe giving birth suggest that he will be forced to have more children eventually. (DW: The Long Game)
- Jack has direct or indirect knowledge of the Cybermen of our universe. (TW: Cyberwoman)
- In 1909, while working for an unknown employer, he stole diamonds from a mine in Lahore. (torchwood.org.uk) One of his soldiers ended up accidentally killing a Chosen One, as a result of which, fairies killed every one of the men except Jack. (TW: Small Worlds)
- The fairies spared Jack, for unknown reasons, perhaps because, having already gained immortality by then, he couldn't die. It is also possible that he was spared simply because he wasn't with them at the time they ran over the Chosen One.
- In the early 20th century, Jack pursued a serious relationship with Estelle Cole. They had wanted to spend the rest of their lives together, but it never happened. Estelle never found out about Jack's life as a space-time traveler. (TW: Small Worlds)
- Jack related to a captive that he had experience in torturing prisoners, and that, "a long time ago", he had "quite a reputation as the go-to guy" in the event of needing to force information out of a person. (TW: Countrycide)
- Given that he wanted to frighten a prisoner into divulging information at the time, he may have lied or stretched the truth. However, given the treatment of Jack's friend at the hand of his torturers, Jack may well have sought revenge against their enemy in this way—and it is not known what skills his job as a Time Agent required him to develop and utilise. The Torchwood 3 team do not seem to know of any such past. This might give more credence to the possibility that he lied, but, taking into account the secrecy with which Jack surrounds himself, it is more likely that he simply did not want to show that side of his personality to them, or preferred to keep such talents to himself until necessary.
- He once worked for an employer named Victor, who surprised "his" staff by coming out as a male-to-female transsexual. (TW: Greeks Bearing Gifts)
- Jack implied that he was present at the extinction of the dinosaurs, and said that he had eaten Pterodactyl, stating that: "...there was nothing else around after the meteor hit". (TW: Fragments)
- At some point, and over an unknown period of time, Jack makes a number of top secret video recordings providing information on the various alien races encountered by planet Earth. The timing of these recordings and why they were made, remains unknown. (Captain Jack's Monster Files)
- The canonicity of the Captain Jack's Monster Files recordings, some of which appear to show Jack in the Torchwood 3 hub, is not confirmed.
Key life events
- Jack's home planet is invaded by an unidentified race of aliens, resulting in his father being killed and his brother vanishing, leaving only him and his mother. (mentioned in TW: Adam)
- Jack enters the military with a friend, who also joins, at Jack's urging. The friend undergoes torture by their foe.
- Jack works for the Time Agency until, finding two years of memory gone (DW: The Empty Child and The Doctor Dances), leaves the Agency and met with another Time Agent, John Hart around this time. (TW: Kiss Kiss, Bang Bang)

- Returns to Torchwood.
Behind the Scenes
- Jack Harkness' first name was originally "Jax", in Russell T. Davies's original production outline. In this Jack's proper name was Jax, and he was using the Jack alias as a cover in World War II. The name was later abandoned due to its similarity to other names in the wider Doctor Who Universe.
- Jack appeared in Series 1 of Doctor Who and both Series 1 and Series 2 of Torchwood. He has appeared during the second half of Series 3 of Doctor Who in the episode Utopia. John Barrowman returned as Jack for Series 4 of Doctor Who.
- In the 1968 Second Doctor episode The Mind Robber, the Master of Fiction wrote the Adventures of Captain Jack Harkaway. This could have been the inspiration for the character's name.
- Jack returned to Doctor Who in Series 4 in The Stolen Earth and Journey's End along with Ianto Jones and Gwen Cooper .
- John Barrowman revealed that Cpt. Jack does sleep, and that he has a bed located down a ladder underneath a manhole cover near his office. (Revealed on the Friday Night Project)
- Jack Harkness has the distinction of being the first ongoing character in the televised Doctor Who universe to be confirmed as being non-heterosexual (although, as described above, it is not strictly correct to refer to him as homo- or bi-sexual, either, more omni-sexual). However, in the expanded Doctor Who universe he is far from the first, as Third Doctor-era recurring character Mike Yates was "outed" as being gay in the novel Happy Endings, while in the Doctor Who Magazine comic strip, Eighth Doctor companion Izzy Sinclair came out as a lesbian in Oblivion.
- Jack is an antithesis of the Doctor in a way. They both wear a trenchcoat and have the ability to overcome death.
- Davies has said he got the surname Harkness from Agatha Harkness, a recurring character in the Marvel comic Fantasic Four
