Jack Harkness


 * This article is about Captain Jack Harkness of Torchwood 3. For other uses of Jack Harkness, see Captain Jack Harkness (disambiguation).


 * "Captain Jack Harkness, who the hell are you?!"

Captain Jack Harkness (sometimes simply "Captain Jack" to those close to him, or as the Doctor refers to him Captain), was the name adopted by a con man from the 51st century and an associate of the Doctor. His original identity remains a mystery; whenever asked he refuses to answer. Reluctantly immortal and stranded on early 21st century Earth, he headed Torchwood Three.

Biography

 * Given his frequent time traveling, 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 and Escapades
Jack was brought up on the Boeshane Peninsula, in a sandy beach-like area. He often played with his brother Gray and his father, Franklin. 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)

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 whose attitudes towards sex differed from 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)), the most accurate term for Jack would be "pansexual" or "omnisexual".

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". 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)


 * It is likely these creature were the same ones who invaded the Boeshane Peninsula.

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 worked as a Time Agent with a partner (in more ways than one) called John Hart. At some point, they spent five years trapped in a two-week time loop, 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) Jack eventually discovered that the Agency had erased two years of his memory, two years he wanted to have back. (DW:The Empty Child)

As a Con Man
While in 1941, he assumed the alias of an American volunteer Captain Jack Harkness, who had died in action that January. 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).

Having left the Time Agency, Jack became 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. Finding pieces of space junk and directing them to soon-to-be disaster sites, Jack would intend on selling them to passers by, then allowing the items to get destroyed before the buyers could pick up their merchandise. He would, at some point, improperly acquire a small, sleek Chula spacecraft, fitted for Human use, which could turn invisible. (DW: The Empty Child)



As a companion
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 ship. Quickly deducing that 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) Jack subsequently became a new travelling companion for the Doctor, to the delight of both Rose (who found Jack attractive) and Jack (who found the Doctor likewise).

The trio shared numerous adventures together, and clicked as a team to the point where Mickey Smith found himself almost an outsider during a shared adventure (DW: Boom Town).

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. Jack later discovered he was immortal from this point on. 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, told Rose that he believed that Jack could begin the process of "rebuilding the Earth". (DW: Children in Need Special). However, this may have been a simple ruse to disguise the fact that the Doctor's instincts told him to run because from this point on Jack became a "fixed point" in time. (DW: Utopia)



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. Jack ended up in 1869, and unfortunately his Vortex Manipulator burned out and he was unable to leave (it was later repaired by the Doctor but disabled twice by him afterwards). (DW: Utopia)


 * Coincidentally or not, the Doctor had first encountered the Rift in that year. (DW: The Unquiet Dead): thus, Jack may have accidently instructed the manipulator to trace the Rift to its point of origin, rather than to locate a specific point in its being, presumably in a haste to relocate the Doctor.

Regardless, he chose to remain in the city, knowing that the Doctor's TARDIS could re-fuel itself using the rift and that the Doctor would one day return there. (TW: Fragments) Jack appears to have chosen to continue using the Harkness alias, or at least was using it as of 1899.

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, and could recover from any degree of physical harm, including death itself, given a few minutes time. (DW: Utopia)

In 1898 he helped save a boy, Anthony, from a Lawphorum, which had fallen to Earth. Anthony, a travelling stage show boy, had failed to predict the future of Jack when he asked him how he would die. (DWF: Best Friends) Probably he decided to take up this idea and so he joined a travelling show and was billed as "the man who couldn't die" in order to investigate the Night Travellers. (TW: From Out of the Rain)

Recruitment by Torchwood
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 they knew Jack had mentioned in various conversations around the city. He was released on the condition that he worked for them, an offer which he intially refused outright. The two asked him to reconsider this option, and Jack wound up in a bar, alone until a young cartomancer offered to read him his fortune. To his immense surprise and bewilderment, she imparted a completely accurate prophecy of The Doctor's eventual return to Cardiff 100 years into the future. Left with nothing to do but wait for a full century, Jack reconsidered Torchwood's offer and began working 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. (TW: Fragments)

He continued working for Torchwood for about a hundred years, still pursuing his attempt to find the Doctor in the meantime. (TW: Fragments)

20th century
In 1909, Jack was travelling through Lahore by train with a group of soldiers under his command, when they were killed by Fairies. Some of the soldiers had recently run over and killed one of the Fairies' Chosen Ones. In revenge, the Fairies suffocated the soldiers by forcing rose petals down their throats (TW: Small Worlds). Jack's presence in Lahore was part of a con intended to steal the diamond shipments the soldiers were guarding (WEB: torchwood.org.uk); however, he did appear to take his responsibility for the men seriously, however temporary it may have been, and to be distressed by their deaths. His participation in the con itself was at the direction of (or at least in cooperation with) an unknown agent (WEB: torchwood.org.uk).

Jack left Torchwood to fight in World War I. In 1914 the Doctor met a soldier who mentioned to him that Captain Harkness had survived a bullet to the head and was recovering in hospital. (IDW: The Forgotten)

Prior to February 1944, he met Estelle Cole (WEB: 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)


 * (Jack's long involvement with Torchwood overlaps the Doctor's involvement with UNIT, supporting the notion that Jack may have played a part in Utopia)

In 1965, the alien race known as the 456, communicating through radio, set up a deal where Jack, along with three other military :officers, whose names he did not know at the time, would deliver to them twelve young orphans as a "gift" at a meeting point in Scotland. In exchange for the children, the unseen aliens would give to them a cure for a new strain of Indonesian flu that the aliens claimed would mutate and kill 25 million people. (TW: Children of Earth: Day Four)


 * By his own admittance, circa 1975 Jack adopted a swinger "disco" lifestyle (BBCR: The Dead Line).

In 1975, Jack and another Torchwood agent, Lucia Moretti, had a daughter, Melissa Moretti, who would age normally. Lucia and Jack split up sometime prior to 1977, and at the request of her mother, their daughter was sent into the Witness Protection Programme, relocated and given the name of Alice Sangster, presumably arising from her mother's fear of the immortal Captain Jack. The application was approved on February 14, 1977. Although Jack was a Torchwood agent at this time, he was still considered a freelance operative rather than a full-time employee. (TW: Children of Earth: Day Three)
 * Jack became leader of Torchwood 3 on New Year's Day 2000 after the previous leader, Alex Hopkins, killed his team. Knowing Jack couldn't die, he did not attempt to kill Jack and waited for him to arrive at the Hub before committing suicide himself. That left Jack as Torchwood Three's leader and only member. (TW: Fragments)



As leader of Torchwood 3
Jack recruited Toshiko Sato in either 2003 (TW: Fragments) or 2005 (TW: Greeks Bearing Gifts) and Owen Harper was recruited in 2006. (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 Three and based mere feet from the TARDIS' arrival at the time. (DW: Boom Town)

After the destruction of Torchwood One in the Battle of Canary Wharf, Jack still continued to run Torchwood Three. With Torchwood One gone and Torchwood Four having "gotten lost", Jack ran Torchwood Three 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) 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 Three's nerve centre, 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 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 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 resulted in Jack remaining 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. From inside of the Hub, Jack recognised the sound of the TARDIS materialising, elated after decades of waiting by the knowledge that the young cartomancer's prophecy had been fulfilled and that a version of the Doctor he knew was returning to refuel. 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
Having heard the TARDIS, Jack fled from the Hub chasing after the sound. With the Doctor's hand in a backpack managed to jump onto the ship before it dematerialised and re-materialised in the year 100,000,000,000,000. The Doctor and Jack had an awkward reunion. Jack made the happy discovery, though, that Rose Tyler had not been killed in the Battle of Canary Wharf. They met Professor Yana, actually the Master, who regenerated and took off in the TARDIS. (DW: Utopia)


 * For a full discussion of these incarnations of the Master, see Yana and Harold Saxon.

The Doctor, Jack and Martha traveled back to 2007 with the aid of Jack's vortex manipulator (part of his Time Agency wrist strap, which the Doctor modified. The newly regenerated Master had gotten elected as Prime Minister in order was captured on the Valiant along with the Doctor, but gave his Vortex Manipulator to Martha, allowing her to escape by teleporting to the ground. (DW: The Sound of Drums) After being imprisoned within the Valiant for one year, the Doctor and Jack managed to release themselves, and Jack destroyed the Master'sParadox Machine with a machine gun. The Master tried to escape in the confusion, but a returning Jack caught him as he attempted to get away. He witnessed the death of the Master and later decided to return to Torchwood. (DW: Last of the Time Lords)

The year Jack spent on the Valiant'' then no longer existed in the main timeline, although Jack remembered it. See The Year That Never Was.''

Return to Torchwood 3
Jack returned to Torchwood and the team, saving the life of a woman being menaced by a Blowfish. While this took place, there was some Rift activity and 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. John caused quite a bit of trouble before leaving Cardiff via the Rift, but disclosed to Jack that his brother Gray had been found. (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 anextradimensional 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 in an attempt to kill all the members of the Torchwood 3 team. This failed and Jack found a message from John on his Vortex Manipulator, which included an appearance by Gray himself. Left shaken, Jack immediately went back to the Hub to confront Captain Hart, leaving the other members of the team to deal with their respective challenges. (TW: Fragments) On meeting John again, Jack was killed before being chained up and made to listen whilst John explains his predicament. Jack's rogue partner then detonated strategically-placed bombs in and around Cardiff, obliterating the city to Jack's horror before forcibly kidnapping him and sending both of them back through time to Cardiff in 27 AD. Here, Jack discovered that John was being manipulated by Gray, whose return is marked by his instantaneous, remorseless murder of his brother. He vengefully forces John to bury Jack alive 20 feet underground in the land that would become Cardiff. Gray, transformed into a merciless, sadistic psychopath by a lifetime of horrific torture had blamed Jack for letting go of his hand when they were children, and wanted Jack to experience a similar never-ending pain by choking on dirt, thrashing on the edge of life every time he revived, only to die again. (TW: Exit Wounds) Before totally burying Jack, John, finally pushed too far by the awareness of how wrong his actions were, slipped a signet ring into the grave with him, hoping that the signal it emitted could be used to locate Jack.

Stuck in a cycle of death and resurrection for centuries, Jack was discovered by Alice Guppy and Charles Gaskell of the Torchwood of 1901, who had picked up the signal of John's ring (an act which confused his Time Agent partner, who had returned to the 21st century to rescue him, thinking that the ring, despite being 'guaranteed 5 millenia', had malfunctioned). Back in the early 20th century, Jack, insistent that he could not be allowed to cross his own timeline (for by now two versions of Jack were present - his past self and present self) demanded to be placed in cryopreservation for 110 years until the present day. Despite being baffled, the two granted him this request and Jack awoke again inside Torchwood Three concurrent to Gray's mayhem - and coincidentally preventing him from finishing off Toshiko with a bullet. Jack forgives his brother of his trespasses despite Gray's own unwillingness to absolve Jack, begrudging him everything. Left with no other option, a tearful Jack chloroformed and cryopreserved 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, determined to find out why Jack finds the time period so interesting, and Torchwood Three reduced to Jack, Ianto and Gwen. (TW: Exit Wounds) On September the 9th, Martha phoned Jack for help with the CERN's Large Hadron Collider. He, Ianto and Gwen flew there, met up with Martha, and investigated 12 accidents, and found a creature that fed on neutrons. (BBCR: Lost Souls)

The Medusa Cascade incident and the 456
Later, when the Earth was relocated by the Daleks to the Medusa Cascade, Harriet Jones, a former Prime Minister and acquaintance of the Doctor, contacted Torchwood and other allies of the Doctor via Sub-Wave Network. After receiving vital information from Martha that allowed him to reactivate his vortex manipulator, Jack teleported to the Doctor's side just as a Dalek shot him. (DW: The Stolen Earth)

Subsequently, after the Doctor's regeneration aborted, Jack boarded the Crucible and surrendered to the Dalek forces. He attempted to shoot the Supreme Dalek and was "exterminated". He subsequently burrowed into the Crucible and linked up with Sarah Jane Smith (with whom he flirted), Mickey Smith and Jackie Tyler. He attempted to use Sarah Jane's Warp star to bluff the Daleks into calling off the detonation of the reality bomb but was ultimately transported to Davros' chamber instead. He helped pilot the TARDIS as it returned the Earth to its original location. He offered Martha Jones a permanent position with Torchwood, and soon after was joined by Mickey, but not before the Doctor deactivated his vortex manipulator once again, refusing to run the risk of allowing him to travel in time. (DW: Journey's End)

Jack, specifically, as part of the team which had negotiated with the 456, was targeted by John Frobisher for assassination after they once more contacted Humanity

by using the children of Earth as their mouthpiece. The British government feared that the secret of the deal wouldcome out. They speculated, incorrectly, that the Hub had special properties which enabled his regenerative abilities, and so set out to destroy it, along with Jack. Jack went to contact his daughter, Alice and grandson Steven, to try to understand what had happened with the children. The government, through a ruse involving their agent, Rupesh Patanjali, killed Jack and planted a bomb inside his body before he revived. Back at the Hub, the bomb exploded, destroying both Jack's body and the Hub. (TW: Children of Earth: Day One) The team conveyed Jack's scattered remains to a holding facility. He slowly regenerated his body and returned to life, but Johnson, a government agent, realizing that destroying the Hub had not rendered Jack mortal, had him encased in concrete. His team, who had survived, rescue him. (TW: Children of Earth: Day Two) The government subsequently captured Jack's daughter and grandson in order to blackmail him into not interfering with plans to negotiate terms wit the aliens in secret. (TW: Children of Earth: Day Three) The next day, Jack and Ianto invaded Thames House to confront the aliens. Stating that they wage war against Humanity, they released a virus which killed Ianto, who died in Jack's arms. (TW: Children of Earth: Day Four) When the bodies had been released and Jack came back to life it was apparent that Captain Jack blamed himself for Ianto's death. (TW: Children of Earth: Day Five)

Jack devised a way to defeat the 456 using a reconstitution wave of a similar wavelength the 456 used to kill Clem, using the children as one vast transmitter, but in order for it to work, the wave needed to be sent via one child. Even though the force of the transmission would kill the child, Jack ignored his daughter's protests and used his grandson, Steven, as the prime transmitter. The plan succeeded, and the 456 left Earth. However, Steven died as a result and Alice severed all contact with Jack. (TW: Children of Earth: Day Five)

Jack then travelled the world for six months. He did not find it enough to rid himself of his guilt. Saying good-bye to Gwen and Rhys, he used his vortex manipulator (which Rhys and Gwen had retrieved from the ruins of Torchwood) to signal a nearby cold fusion freighter near the edge of the Sol system and teleported off into space. (TW: Children of Earth: Day Five)

Undated events

 * As indicated above, Jack has worked for Torchwood since the late 19th century; to date only a handful of his missions prior to the recruitment of Gwen Cooper are known (TW: From Out of the Rain, Fragments, Exit Wounds)
 * Jack once quipped about the time he got pregnant, a memorable experience, though not necessarily in a good way. (TW: Everything Changes)
 * Jack had direct or indirect knowledge of the Cybermen of our universe, (TW: Cyberwoman) and even stated that he knew what would happen in the Cyber-Wars of the future. (CJMF: Cyberman)
 * 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.


 * 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 once had a boyfriend with no mouth. (TW: Fragments)
 * Jack implied that he was present at the extinction of the dinosaurs, and said that he had eaten some of them, stating that: "...there was nothing else around after the meteor hit". (TW: Fragments) Jack appears to be unaware that the extinction of the dinosaurs was caused not by a meteor, but a space freighter that exploded, killing the the Doctor's companion, Adric (DW: Earthshock)
 * At some point, and over an unknown period of time, Jack made 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. (WC: Captain Jack's Monster Files)
 * Although not necessarily "adventures" per se, Jack has made references to having romantic relationships with several 20th century notables, including Christopher Isherwood (TW: Reset) and Marcel Proust (TW: Dead Man Walking).

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). He has died and resurrected many times, such as when he was electrocuted multiple times in (TW: Cyberwoman). By the time John Hart killed him in a warehouse bombing, he had died at least 1,392 times, starting from 1869. (TW: Fragments) However as a benefit and necessity Jack is immune to any attack that would completely destroy him, like a Judoon laser gun. While this is never directly stated, it is implied when he stayed under stet radiation from a rocket ship that completely burns flesh but never even bothered him. (DW: Utopia) In some circumstances, such as when in a scrape with a Weevil (TW: Combat) or pterodactyl (TW: Fragments), Jack heals of all non-fatal 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). He can also re-grow limbs, organs, bones, etc. After a bomb that was planted in his stomach exploded, he was able to fully regenerate from just an arm, a shoulder, and part of his head. His bones grew back first, followed by his internal organs, and lastly his skin. (TW: Children of Earth: Day Two)

The Doctor explained this power to him after their reunion: Rose resurrected him as the Bad Wolf entity with the power of the Time Vortex after his first death, when he was shot by a Dalek. She couldn't totally control the power she wielded and she brought him back forever by accident. The Doctor knew from the moment it happened and so abandoned Jack in the future. The Doctor said that Jack is a fixed point in time, an impossible thing which the Doctor has trouble even looking at and even the TARDIS tries to get rid of. The Doctor says even he's unable to undo Jack's resurrection power and doesn't know if Jack will ever die due to this. (DW: Utopia) 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. Tosh likened it to trying to read a dead man, and Jack confirmed that he knew someone was trying to read his mind. (TW: Greeks Bearing Gifts)

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 (NSA: The Stealers of Dreams).


 * Whether this would make the immortal Jack the actual future Face of Boe remains unknown. If true, then Jack is fated to outlive the earth (DW: Gridlock).
 * In his commentary for a preview of Children of Earth, Russell T Davies said of Captain Jack: "He has lived through hundreds and hundreds of years, and will live through billions of years."

Multiple Jacks
Due to Jack's immortality and time travel, there have been several occasions in which several Jacks existed on Earth at the same time. At the time of Jack's first encounter with the Doctor in World War II, there were three versions on Earth: the young, non-immortal Jack who subsequently joined the Doctor and Rose; an older, immortal Jack working for Torchwood (location at this point in time unknown); and a still older Jack being kept in cryronic sleep in the Torchwood 3 hub in Cardiff. (DW: The Empty Child/The Doctor Dances). Later, when the Doctor, Rose, and Jack arrive in Cardiff prior to the Blaidd Drwg power station incident, they are only feet away from the Torchwood 3 hub where the older Jack is based and the cryogenically frozen Jack awaited resurrection (DW: Boom Town). Yet another trio of Jacks existed on Earth, again during World War II, when the immortal Jack accidentally passed through a rift in time back to World War II, when in fact not only were there three Jack (the 21st century Jack, the 1940s Torchwood member Jack and the frozen Jack) but a fourth as the original user of the name was also present. (TW: Captain Jack Harkness)

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)

Possessions
When Rose and the Doctor first met him, Jack owned a 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) In contrast to The Doctor, Jack Harkness was far more willing to use weapons, and was capable of modifying equipment to that end. Jack owned a sonic blaster. (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 Three, Jack liked to carry a World War II Webley. (TW: Everything Changes onward).

Romantic interests
As an extremely long-lived man, Jack has had many lovers, both male and female and not all strictly human. By nature, Jack flirts with nearly everyone he meets. The earliest known example is his Time Agency partner Captain John Hart (TW: Kiss Kiss, Bang Bang), but Jack has also recalled lovers from his Time Agency days, such as his would-be executioners (a couple) and a boyfriend with no mouth. Some time after leaving the Time Agency, he became a con man during World War II and had an affair with a soldier named Algy. (DW: The Doctor Dances) While traveling at their side, Jack appeared to develop romantic feelings for Rose Tyler and the Ninth Doctor, kissing them both on the mouth upon leaving them to fight the Daleks. (DW: The Parting of the Ways) When once again living around the time of World War II (this time immortal and working for Torchwood) he had a relationship with Estelle Cole (TW: Small Worlds) but seemingly disappeared out of her life forever one day (possibly to go off to war again).

While stranded on Earth between 1869 and 2007, Jack alluded to countless romances. He is known to have dated notables Christopher Isherwood (TW: Reset) and Marcel Proust (TW: Dead Man Walking) and developed a relationship a Torchwood coworker named Greg Bishop (TWN: The Twilight Streets). Other mentions include acrobatic twins and the possibility of a relationships with other coworkers and acquaintances, such as Duchess Eleanor (BBCR: Golden Age). During this period Jack also became married, but outlived his wife. (TW: Something Borrowed) With Torchwood Agent Lucia Moretti, Jack was the father to one Alice Carter (TW: Children of Earth). In the late 1960s, Jack met and had a brief relationship with involuntary time-traveler Michael Bellini. (TWN: Trace Memory) Later, Jack recruited Gwen Cooper, who was romantically drawn to him, and Ianto Jones whom he developed a romantic relationship with. Despite these burgeoning relationships, Jack met the real Captain Jack Harkness after time-traveling back in time and the two developed a romantic bond, culminating in a kiss upon their pained farewell. (TW: Captain Jack Harkness) Jack also met and was attracted to Martha Jones, the handsome Tenth Doctor and even fleetingly to the Malmooth Chantho and a human male refugee. (DW: Utopia) When he returned (TW: Kiss Kiss, Bang Bang), and John Hart departed, he began an exclusive relationship with Ianto, though he continued to flirt with everyone he met. The relationship with Ianto however, was close enough for him to surrender the world to the 456 to stop them killing Ianto. This did not save him, and the relationship was tragically ended. (TW: Children of Earth: Day Four)

Relatives
Jack's known relatives include his mother, his father, Franklin, and his younger brother, Gray. His mother was killed during an attack on the Boeshane Peninsula. The fate of his father is unknown. Gray later turned against his brother and was eventually cryogenically frozen in the Torchwood Hub; the Hub's subsequent destruction during the 456 incident renders Gray's fate unclear. (TW: Children of Earth: Day One)

He also had a mother and at least one wife, whose names are unknown. On Earth, he had a daughter, Alice Carter, and a grandson, Steven Carter; Steven died at the resolution of the 456 incident, and his relationship with his daughter has become estranged. (TW: Children of Earth: Day Five)

The fact his daughter was aging and his grandson died indicates that Jack's immortality cannot be passed genetically.

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.
 * Davies has said he got the surname "Harkness" from Agatha Harkness, a recurring character from the Fantastic Four comic book.
 * John Barrowman revealed that 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, a late-night talk show.) This bed and man hole are seen in Small Worlds
 * Jack Harkness has the distinction of being the first ongoing character in the televised Doctor Who universe to be definitely confirmed as being non-heterosexual (although, as described above, it is not strictly correct to refer to him as homo- or bisexual, either, more omnisexual). However, in the expanded Doctor Who universe he is far from the first, as Seventh Doctor companion Chris Cwej was revealed to be bisexual in the 1996 novel Damaged Goods (written by Russell T Davies), while Third Doctor-era recurring character Mike Yates was "outed" as gay in Happy Endings (although there is no suggestion of this in the televised episodes, which showed him flirting with Jo Grant on occasion). The Doctor Who Magazine Eighth Doctor comics featured recurring character Fey Truscott-Sade and the Doctor's companion Izzy Sinclair came out as a lesbian in her final regular appearance in Oblivion.
 * Much like Nicola Bryant's portrayal of Peri, sometimes Barrowman uses word choices and pronunciations that an American wouldn't use. The most obvious example is in his way of saying "estrogen" in Everything Changes. (This is mainly because the word is spelt oestrogen in British English.) However it needs to be noted that Harkness is not an American, but rather someone from the far future pretending to be one, and it is established that he has spent much of his life (especially after gaining immortality) based in the British Isles or travelling with "British-speaking" companions such as The Doctor and Rose Tyler.
 * Jack Harkness wears the rank slide of a Group Captain but is addressed, incorrectly, as "Captain". However, in his initial appearance in Doctor Who he is incorrectly wearing the cap and insignia of a Squadron Leader.
 * The implication that Jack is destined to become the Face of Boe is not considered set in stone due to Russell T Davies waffling over the issue during the DVD commentary for Last of the Time-Lords in which he would not commit absolutely to Jack becoming the Face in the future. However, in media and public (i.e. science fiction convention) statements, producer Julie Gardner, along with both John Barrowman and David Tennant, have all gone on record as saying that Jack is the Face of Boe.
 * Jack has appeared in every season in the revived series, with an exception of Series 2.
