"'''Captain Jack Harkness'''" was the alias adopted by the [[human]] [[Time Agent]] and [[Con artist|con man]] '''Javic Piotr Thane''' ([[AUDIO]]: {{cs|Month 25 (audio story)}}, {{cs|R&J (audio story)}}) from the [[Boeshane Peninsula]] in the [[51st century]]. He was a [[companion]] of the [[Ninth Doctor]], and an associate of the [[Sixth Doctor|Sixth]], [[Tenth Doctor|Tenth]] and [[Thirteenth Doctor|Thirteenth]] [[The Doctor|Doctor]]s.

Originally a [[Time Agent]], Harkness lost his memories of his previous life and became a [[con artist]]. Upon meeting the [[Ninth Doctor]] and [[Rose Tyler]] in [[1941]], he tried to scam them into buying a [[Chula ambulance]], having mistaken them for fellow Time Agents. After assisting the Doctor and Rose in curing a [[Empty Child Syndrome|plague]] unleashed by rogue [[Chula]] [[nanogene]]s from the crashed ambulance, however, he would go on to join them in their travels in [[The Doctor's TARDIS|the TARDIS]], inspiring him to become a better man.

After he was shot and killed by a [[Dalek]], Jack was revived by Rose, who at the time had been transformed into a [[Bad Wolf (entity)|nearly omnipotent being]] by gazing into the [[heart of the TARDIS]]. Unable to control her powers, she accidentally turned him into an [[immortality|immortal]] being. Because of this, the Doctor saw his companion as a [[fixed point]] — a [[temporal paradox]] that threatened the TARDIS's functionality. Consequently, the Doctor abandoned him in the year [[200,100]] aboard [[Satellite Five|a space station]] orbiting a Dalek-devastated [[Earth]]. Stranded, the former Time Agent had to use his own devices to catch up to the Doctor. He thought it likely that he'd find the Ninth Doctor in the early [[21st century]], since that was Rose's home era. But [[Jack Harkness' vortex manipulator|his vortex manipulator]] failed to deliver him there due to the damage caused when he was exterminated by the Daleks, missing by more than a century — and going on the fritz immediately thereafter. This left the immortal no choice but to simply wait from the mid-[[19th century|19th]] to the early [[21st century]] to reconnect with the Doctor.

During his long wait for the "right Doctor", he experienced what was to him [[Earth]]'s history firsthand and he even served in a few of the well-known conflicts. He also had many different relationships, some of which produced offspring. For the majority of those years, he also worked for [[Torchwood Three]]. After several decades as an informal free-lancer, he eventually became its head in the year [[2000]]. Later that decade, he finally met up with the Doctor, although the [[Time Lord]] had by this time [[regenerated]] into his [[Tenth Doctor|tenth incarnation]] and was now travelling with [[Martha Jones]]. The Doctor told Harkness why he had abandoned him, and explained there was nothing he could to fix Harkness's condition. Together the Doctor, Harkness and Jones thwarted [[the Master]] and his plan to turn Earth into a new [[Gallifrey]] during [[the Year That Never Was]], before Harkness parted ways with them to return to Torchwood.

Over the years, Torchwood lost many of its members. At the dawn of the [[2010]]s, [[the 456]] returned to Earth. Although Torchwood was able to repel the threat, their success came with the loss of their headquarters and the loss of Harkness's grandson, [[Steven Carter]], as well as his teammate and lover, [[Ianto Jones]]. He, therefore, disbanded the group and left Earth. However, he returned during the events of the so-called "[[Miracle Day]]", and a [[Torchwood (team)|new Torchwood]] team arose. Later though, after several further changes to the team, Torchwood lost contact with Harkness, with his exact whereabouts unknown.

Eventually Harkness once again returned to Earth on board a stolen spaceship in [[2020]]. Attempting to warn the Doctor of the threat of the [[Ashad|Lone Cyberman]] and his quest to [[Restoration of the Cyber-Empire|restore]] the [[Cyber-Empire]] in the [[far future]], he was only able to [[Quantican Scoop|scoop]] up [[Team TARDIS|the companions]] of the [[Thirteenth Doctor]] during the [[Gloucester Incident|an invasion]] of [[Judoon]] in [[Gloucester]]. Promising to find the Doctor again when she needed him, he told them of an [[The Alliance (Fugitive of the Judoon)|alliance]] that sent [[Cyberium|something]] the Lone Cyberman was looking for [[Time travel|back in time]] and that, should the Doctor find it, she must not give it to the [[Cyberman]] at any cost. He later proved true to his word, and rescued the Doctor from imprisonment at a [[Judoon prison]], before assisting her and her companions in repelling the Daleks [[Security Drone Incident|once more]] in [[2021]]. With the threat of the Cybermen in the future already neutralised, Harkness went off to catch up with [[Gwen Cooper]], his former teammate at Torchwood.

An important facet of Jack's existence on [[Earth]] was its temporal complexity. There were whole decades when multiple versions of Jack existed on Earth. Indeed, during the whole of the [[20th century]], there were always at least two Jacks on Earth since a younger version was a part of Torchwood Three and an older one was in a grave dug by [[Gray (Adam)|his brother]] in ancient [[Britain]]. During the [[World War II]] era, Earth had at least one more Jack — the younger "con artist" who first met the Doctor and Rose.

== Biography ==
=== Early life ===
[[File:Young jack.jpg|thumb|left|Javic on Boeshane Peninsula. ([[TV]]: {{cs|Adam (TV story)}})]]
Javic Piotr Thane was born before the year [[5094]]<ref>In [[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}, [[Captain]] [[John Hart (Kiss Kiss, Bang Bang)|John Hart]] refers to him as "[[Rear of the Year]], '''5094'''".</ref> ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}) to [[Franklin (Adam)|Franklin]] and [[Jack Harkness' mother|his wife]]. He had a younger brother called [[Gray (Adam)|Gray]]. ([[TV]]: {{cs|Adam (TV story)}}) He was raised on the [[Boeshane Peninsula]] ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) where he spent time with his brother and father playing [[cricket]] and singing around a [[campfire]]. ([[TV]]: {{cs|Adam (TV story)}})

On what he would later call the worst day of his life, Javic fled from a host of creatures with Gray and lost him in the [[confusion]] when he accidentally let go of his hand. He returned home and found his mother crying over his father's body. He spent years looking for Gray without success, eventually burying the [[memory]] of what happened as well as his happy memories of his father. ([[TV]]: {{cs|Adam (TV story)}})

Javic persuaded [[Jack Harkness' best friend|his best friend]] to "join up" with him to fight the creatures. They were captured, and the enemy thought Javic's friend the weaker of the pair and tortured him as a lesson for Javic. They let Javic go, to bear the guilt of his friend's fate. ([[TV]]: {{cs|Captain Jack Harkness (TV story)}})

In 5094, Javic won the [[Rear of the Year]] award. ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}})

=== The Time Agency ===
{{section stub|Info from {{cs|Month 25 (audio story)}} needs to be added}}
Javic was the first Boeshane resident to be signed up for the [[Time Agency]], making him a "poster boy" for the area, known as the "Face of Boe". ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) Going undercover during [[World War II]] in [[1941]], Javic assumed the identity of an [[United States|American]] volunteer named [[Jack Harkness (Captain Jack Harkness)|Captain Jack Harkness]], who had died in action the January prior. He knew very little about the real Jack, other than basic information such as the date and manner of his death. ([[TV]]: {{cs|Captain Jack Harkness (TV story)}})

On one of his first missions for the Time Agency, Jack fought the [[Navigator (species)|Navigators]] ([[COMIC]]: {{cs|World Without End (comic story)}}) and went to a [[black market]] on [[Fluren's World]] to bid on a Monstrom Time Destroyer, but lost it to a pair of [[Wrightosaur]] mercenaries, whom he also had a sexual encounter with. ([[COMIC]]: {{cs|Weapons of Past Destruction (comic story)}}) He later spent some time living as a [[Priest]] in the [[17th century]], under the alias of "Father Julian Horst". ([[COMIC]]: {{cs|Slaver's Song (comic story)}})

Jack worked as a [[Time Agency|Time Agent]] with [[John Hart]], a partner both professionally and sexually. They once spent five years trapped in a two-week [[time loop]], becoming the equivalent of a married couple after spending so much time together. Hart admitted to having been "a good wife", closing an argument between the two as to the details of the relationship. ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}) On another occasion, the two agents faced off against a horde of [[Weeping Angel]]s. ([[COMIC]]: {{cs|Secret Agent Man (comic story)}})

Once, when [[death sentence|sentenced to death]], Jack ordered four [[hypervodka]]s as a last meal and ended up bedding both executioners at the same time. He recalled them as a lovely couple who kept in touch. ([[TV]]: {{cs|The Doctor Dances (TV story)}})

While still a Time Agent, ([[COMIC]]: {{cs|Secret Agent Man (comic story)}}) Jack acquired a small, sleek [[Chula warship]] fitted for [[human]] use, which could turn invisible. ([[TV]]: {{cs|The Empty Child (TV story)}})

Jack found that the Agency had erased two years of his memory, ([[TV]]: {{cs|The Empty Child (TV story)}}) which other Time Agents like Hart refused to discuss with him. ([[COMIC]]: {{cs|Secret Agent Man (comic story)}}) He left the Agency and became a time-travelling con artist, running scams using his knowledge of future events. His preferred schemes involved collecting payment for items he knew would be destroyed before the buyer could see it. Finding pieces of space junk and directing them to the soon-to-be disaster sites, Jack would sell them to passers-by, then allow the items to be destroyed before the buyers could pick up their merchandise. ([[TV]]: {{cs|The Empty Child (TV story)}})

=== Adventures with the Ninth Doctor ===
{{section stub|Info from ''[[Doctormania (comic story)|Doctormania]]'', ''[[The Transformed (comic story)|The Transformed]]'', ''[[Official Secrets (comic story)|Official Secrets]]'', {{cs|Slaver's Song (comic story)}}, ''[[Sin-Eaters (comic story)|Sin-Eaters]]'', {{cs|Supremacy of the Cybermen (comic story)}}, ''[[Christmas Special (WEB short story)|Christmas Special]]'' & {{cs|The Deviant Strain (novel)}} needs to be added}}
Though there are records of Jack having already been travelling with the [[Ninth Doctor]] when the Time Lord met [[Rose Tyler]], ([[PROSE]]: {{cs|Dr. Ninth (novel)}}) the most common account of the Doctor and Jack's first encounter states that while running a scam involving a [[Chula ambulance]] in the [[London Blitz]], Jack spotted [[Rose Tyler]] hanging from a [[barrage balloon]]. Just as she fell, he rescued her and took her aboard his ship. Deducing she came from the future, and thinking she was a Time Agent, he tried conning her into purchasing the ambulance. Upon meeting Rose's "companion", the [[Ninth Doctor]], Jack realised that they were just freelancers like he was. The Doctor pointed out that the landing site of the ambulance was where the ground zero of the [[Empty Child]] plague started. Jack believed the object was empty space junk, ([[TV]]: {{cs|The Empty Child (TV story)}}) but in fact, the ambulance contained [[nanogene]]s. The nanogenes had not seen a human before; they took the gas mask for the deceased [[Jamie (The Empty Child)|child's]] face and fused it to him, spreading to other people who touched him, also transforming them into undead creatures with no life signs.

Jack teleported the Doctor and Rose to his warship to JEWS ARE SUBHUMAN FILTH, and they went to the bombsite near the hospital, where they realised the truth. The ambulance started its emergency protocols, calling the creatures, who had been armed as "[[Chula]] warriors", and was ready to "tear the world apart" to find the boy's mother.

[[File:Jack Love the t-shirt.jpg|thumb|left|Jack saves the [[Ninth Doctor]] and Rose from the falling bomb. ([[TV]]: {{cs|The Doctor Dances (TV story)}})]]
Every patient and soldier at the bombsite converged on the Doctor, Rose and Jack. The Doctor fixed the nanogenes' mistakes by comparing the DNA of the child and [[Nancy (The Empty Child)|Nancy]], who was his mother, restoring the infected zombies to normal. Jack stopped the bomb from hitting the bomb site by placing it in stasis inside his warship and when everyone got to safety, the Doctor destroyed the ambulance, making sure that history said that a bomb hit that location. The Doctor rescued Jack from his Chula warship just before it exploded, taking him aboard [[The Doctor's TARDIS|the TARDIS]] as his latest companion, to the delight of both Rose, who found Jack attractive, and Jack, who found both Rose and the Doctor attractive. ([[TV]]: {{cs|The Doctor Dances (TV story)}})

The Doctor took Rose and Jack to where the planet [[Excroth]] should have been but found it was gone. The TARDIS was taken aboard a [[Lect]] spaceship, but the Doctor and Jack escaped after it was attacked by [[Unon]], after Jack shot one of them. However, Rose was blasted into the [[Time Vortex]] but was protected from the [[time wind]]s by the [[tachyon inhibitor]] she found. Jack tracked Rose down to the [[Fluren Temporal Bazaar]]. The Doctor called the attention of the Unon but attracted the Lect who attacked one another, and which subsequently led to the emergency protocol being triggered, dissipating the [[time bubble]] protecting [[Fluren's World]]. Separated from Rose, Jack, in the TARDIS, was captured and taken to the [[Unon]]'s [[Perpetual City]], where he reunited with the Doctor, who he believed to have died.

[[Arnora]], mother superior of the Unon, tricked the Doctor into coming to the planet [[Traxis]] with Jack, and the Doctor used a [[temporal stabiliser]] to seal a [[time fissure]]. After Rose tricked the Doctor into giving the co-ordinates of the Perpetual City to the Lect, [[Evja]], the Grand High Seer of the Unon, took Jack to a [[sub-dimensional void]]. In the void, Jack saw what future would come if the Doctor wasn't around and the Unon was in charge of time. Released from the void, Jack and Evja saved the Doctor. After Arnora was killed by the Lect, the Doctor, unable to stop the overloading [[entropy engine]], took as many Unon as he could to another world so they could start again. ([[COMIC]]: {{cs|Weapons of Past Destruction (comic story)}})

Visiting the [[Eye of Orion]], Jack, Rose and the Doctor found a giant ziggurat and the [[Hanging Gardens of Slarvia]], which had been destroyed centuries before.
The Doctor used his sonic screwdriver to discover a ship in orbit, which transmatted them on board and brought them face to face with [[Taggani]], the most famous geohacker in history. They stopped him from using the Doctor's memories to recreate everything lost in the [[Last Great Time War]], and exposed his true identity as an art historian from the [[Braxiatel Collection]] before handing him over to the [[Judoon]]. ([[COMIC]]: {{cs|Hacked (comic story)}})

While on [[Clix]], Jack and the Doctor disguised themselves as [[Slitheen]]s to find Rose, who had been kidnapped by [[Slist Fayflut Marteveerthon Slitheen]]. ([[COMIC]]: {{cs|Doctormania (comic story)}})

The trio shared numerous adventures together, including encountering [[Russia]]n special forces and the [[Novrosk spaceship]]. ([[PROSE]]: {{cs|The Deviant Strain (novel)}})

Jack later spent a month in [[2006]] [[Bromley]], helping a [[Neanderthal]] named [[Das (Only Human)|Das]] to fit in with [[21st century]] society. ([[PROSE]]: {{cs|Only Human (novel)}})

When the TARDIS became powerless to travel through time, the three travellers stopped off in [[Cardiff]] in 2006 so that the TARDIS could refuel via a scar in a [[Cardiff Space-Time Rift|rift]] running through the city. Whilst in Cardiff, Jack met Rose's estranged boyfriend, [[Mickey Smith]]. Together, they captured [[Blon Fel-Fotch Passameer-Day Slitheen|Blon]], the sole [[Slitheen family|Slitheen]] survivor of a prior attack on [[10 Downing Street]] who had become Lord Mayor. When the TARDIS was refuelled, they stopped off at [[Raxacoricofallapatorius]] to return her home. ([[TV]]: {{cs|Boom Town (TV story)}})

Afterwards, they visited [[Arkannis Major]] in [[2775]], where Jack was committed to an asylum for telling fictional stories. ([[PROSE]]: {{cs|The Stealers of Dreams (novel)}})

At some point, the Doctor, Rose and Jack went to [[New Vegas]] in the [[23rd century]], where they assisted detective [[James McNeil]] to investigate [[The Whisper]], a strange vigilante that had terrorised the city's underworld. This involved Jack working undercover as a reporter for the ''Daily Galaxy'', where he befriended [[Daisy Hewett]], but she later betrayed him to Mafia boss [[Cyrus Wolfsbane]], who kidnapped Jack so that the Doctor would lead him to the Whisper, with Cyrus subsequently killing the Whisper. ([[AUDIO]]: {{cs|Night of the Whisper (audio story)}})

After visiting [[Kyoto]], [[Japan]] in [[1336]], Jack, the Doctor and Rose were abducted by [[transmat]] beams, and awoke on the [[Satellite Five|Game Station]]. Jack found himself on a makeover game show hosted by [[Trine-E]] and [[Zu-Zana]]. When the android hosts threatened him, he shot them, and improvised a more powerful gun out of their [[defabricator]].

Jack met up with the Doctor and an escapee from the deadly games, [[Lynda Moss]], and tracked down Rose. They raced to save Rose from ''[[The Weakest Link]]'' hosted by a deadly [[Anne Droid]]; they were unsuccessful in preventing the Anne Droid from seemingly killing Rose. Completely heartbroken, Jack was tempted to shoot the staff behind the games and threatened to kill the guards when they arrested the Doctor and Lynda, only to get arrested himself for breaking in and out of the games. However, he and the Doctor physically overpowered the guards and set off to stop the deadly "entertainment".

Taking "hostages" in the control room, Jack found the TARDIS stowed away in an archive room. Using the TARDIS, he discovered the laser that "killed" the games' losers was actually teleporting them across space. Puzzled, the Doctor discovered that the Game Station was unknowingly broadcasting a secondary signal to an empty location of space, which was where all the losers ended up. Disabling the signal, the Doctor was horrified to find two hundred [[Dalek]] battleships. Establishing contact, the Doctor learned his old foes had taken Rose hostage, but promised the Daleks that he would rescue her and destroy them for the final time. ([[TV]]: {{cs|Bad Wolf (TV story)}})

Jack and the Doctor flew the TARDIS into the Dalek mothership, rescued Rose and discovered the [[Dalek Emperor]] was controlling the Game Station and turning the contestants into Daleks. Returning to the Game Station to prepare for the battle ahead, Jack formed a resistance group consisting of contestants and staff members to fight the Daleks. Knowing he was fighting a losing battle and would most certainly perish, Jack [[kiss]]ed Rose and the Doctor goodbye. In the ensuing battle, all of the resistance were killed and the Doctor sent Rose home in the TARDIS. Now the last man fighting, Jack was killed defending the satellite against the Daleks as they attacked the Game Station, and seemingly accepted his death. Rose Tyler, while holding the powers of the [[Time Vortex]] which turned her into the [[Bad Wolf (entity)|Bad Wolf]], returned to the Game Station, destroyed the Daleks, and resurrected Jack. The TARDIS departed before Jack could rejoin them since his new immortal nature perverted the [[Laws of Time]], and would interfere with the operations of the TARDIS. He was left stranded on the satellite. ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) Rose couldn't control her powers and had brought Jack back to life forever, making him immortal, and as the Doctor claimed, a fixed point in time. ([[TV]]: {{cs|Utopia (TV story)}})

Shortly following the Doctor's [[regeneration]] going wrong, Rose suggested going back to find Jack, thinking he might be able to help; the Doctor claimed that he was busy rebuilding the Earth, not yet wishing to tell her the truth about what had just happened. ([[TV]]: {{cs|Born Again (TV story)}})

Somehow making his way to the ravaged Earth, Jack, though recognised as a hero for his fight against the Daleks, chose to live as a recluse in a small cabin located near the ruins of the [[Black Country Dome]]. A [[200101|year]] passed, and Jack found himself approached by [[Silo Crook]], an aspiring reporter. Though Jack vehemently wished to be left alone, both shared a suspicion of the [[Hope Foundation]], a charity founded by [[Vortia Trear]] ostensibly to take the surviving humans off Earth and give them new, better lives. Sneaking aboard [[Trear Station]], repurposed from the Game Station along with several [[starliner]]s and a couple of [[freight ship]]s, Jack reunited with Silo and found that Vortia was part of a rich elite which had always looked out for themselves and intended to exploit those below them. In the ensuing revolt, Trear was deposed and the station was left falling to [[Earth]], forcing Jack to interact with live cables to land it safely. Reviving after being [[electrocute]]d, Jack reasoned that the universe liked him and saw that an abundance of resources was salvaged from the grounded station, confident that humanity would ultimately rebuild itself. ([[AUDIO]]: {{cs|The Year After I Died (audio story)}})

=== Life on past Earth ===
==== 19th century ====
Eventually, Jack used the [[Jack Harkness' vortex manipulator|vortex manipulator]] in his Time Agency wrist strap to return to [[Cardiff]], the site of an active [[Cardiff Space-Time Rift|space-time rift]]. Jack knew that the TARDIS could refuel itself using the rift, and therefore attempted to reach there in the early 21st century so that he could find the Doctor again. However, Jack ended up in [[1869]], and his vortex manipulator burned out, leaving him stranded. ([[TV]]: {{cs|Utopia (TV story)}})

Jack stayed in Cardiff, choosing to continue using the Harkness alias (or at least using it when he started working for [[Torchwood Three]]). ([[TV]]: {{cs|Fragments (TV story)}}) His third death and resurrection occurred when he was shot in [[1892]] during a fight on [[Ellis Island]]. Jack found that he still aged, but very slowly — he noted that he had a couple of grey hairs in the 2000s,{{note|name="drums"|According to the episode {{cs|The Sound of Drums (TV story)}}, [[Martha Jones]]' present day during [[Series 3 (Doctor Who)|series 3]] of ''[[Doctor Who]]'' takes place over a six-day period, with {{Simm}} being elected three days after ''Smith and Jones'', and the [[Toclafane]] [[Toclafane invasion|invading Earth]] five days after ''Smith and Jones''. However, [[Aliens of London dating controversy|sources differ on which dates these stories are set]]. According to [[PROSE]]: {{cs|The Paradox Moon (short story)}}, the Toclafane invasion happens on [[23 June]] [[2007]], placing the events of ''Smith and Jones'' on [[18 June]]. According to [[AUDIO]]: {{cs|Hysteria (audio story)}}, ''Smith and Jones'' takes place in [[2008]], with a [[UNIT]] mission log in [[AUDIO]]: {{cs|Recruits (audio story)}} referring to the recovery of moon rocks from [[Royal Hope Hospital]] in [[March]] 2008. A newspaper clipping in [[PROSE]]: {{cs|The Secret Lives of Monsters (short story)}} places ''Smith and Jones'' on a [[Sunday]] [[4 June]], thus placing the Toclafane invasion on [[Friday]] [[9 June]]. In the real world, these dates do not fall on a Sunday and Friday in either 2007 or 2008.}} over 100 years after arriving in Cardiff ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) — and could recover from any degree of physical harm, including death itself, given a few minutes time. ([[TV]]: {{cs|Utopia (TV story)}})

In [[1898]], Jack went to the music hall performance of [[Anthony Bradshaw]], also known as "the Wonder of 1898", who could foretell the future through his invisible friend the [[Lawphoram]]. Jack asked him, "how will I die?" and Anthony did not know. When [[Edward Hardiman]], Anthony's "uncle", tried to leave the theatre, Jack stopped him, and told him to scram after buying Anthony from a workhouse [[1897|the previous year]]. Jack forced the Lawphoram, a creature from the future which was feeding on Anthony's mind, out of Anthony using the [[Jack Harkness' vortex manipulator|vortex manipulator on Jack's wrist]]. He cradled Anthony, promising him he'd be all right. ([[PROSE]]: {{cs|Best Friends (short story)}})

[[File:9kkkk.jpg|thumb|left|Jack in [[1899]]. ([[TV]]: {{cs|Fragments (TV story)}})]]
In [[1899]], [[Torchwood Three|Torchwood Cardiff]] agents [[Alice Guppy]] and [[Emily Holroyd]] found out about Jack. They captured and tortured him to discover why he could not die and what connection he had to [[the Doctor]], who the [[Torchwood Institute]] had designated an enemy. After telling them that the Doctor was a hero who would save them from aliens, Jack was released on the condition that he undertake a mission for Torchwood. Jack was sent to stop a criminal [[Blowfish]], which he returned to Torchwood Three's Hub, only to see it killed by a shot to the head. Disgusted by Torchwood's methods, Jack walked away from the organisation. He ended up in a bar, where he drowned his sorrows alone until [[Little girl (Dead Man Walking)|a young cartomancer]] offered to read him his fortune. She gave a completely accurate prophecy of the Doctor's [[Utopia (TV story)|eventual return to Cardiff 100 years into the future]]. Left with nothing to do but wait for a full century until his version of the Doctor coincided with his timeline, Jack reconsidered Torchwood's offer and began working for them and awaiting the Doctor's return.

Jack continued working for Torchwood for over a hundred years, still pursuing his goal of finding the Doctor in the meantime. ([[TV]]: {{cs|Fragments (TV story)}})

Shortly after this, Jack and the rest of Torchwood infiltrated and destroyed the [[HMS Hades|HMS ''Hades'']] after it was found to be a lab for experimenting on aliens. ([[PROSE]]: {{cs|The Baby Farmers (short story)}})

On [[17 May]] 1899, Jack was temporarily working with the [[London]] [[Torchwood One|branch]] of Torchwood based at the [[Natural History Museum]]. The [[Life-stealer]] escaped custody and started feeding on the youth of Londoners at the same time Torchwood was being visited by [[Queen]] [[Victoria]] for her annual inspection of the Institute, resulting in him sharing an adventure with the Queen as she took to pursuing the creature. After Victoria killed the creature by exploiting its weakness against the elderly, Jack declined her offer to take command of Torchwood London, the position having been left vacant when its [[Archie (The Twilight Streets)|previous director]] was rendered rapidly aged permanently incapacitated, telling her that his place was in Cardiff. ([[AUDIO]]: {{cs|The Victorian Age (audio story)}})

Jack went to [[China]] during the [[Boxer Rebellion]], where he worked with explosives. ([[TV]]: {{cs|The Blood Line (TV story)}})

Jack presented Torchwood‘s findings about [[Object 1]] to Queen Victoria. She ordered him to get rid of it by throwing it into the Rift. He took it back to Cardiff but neglected to follow her orders, hoping the Object's temporal effects might attract the Doctor. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

==== 20th century ====
In [[1902]], Jack investigated strange visions at [[Ravenhall Manor]], a Gothic 18th century house. He defeated the creature responsible. ([[COMIC]]: {{cs|Hell House (comic story)}})

In [[1906]], Jack set up a bank account, the interest of which would lead to a small fortune by 2011. ([[TV]]: {{cs|Dead of Night (TV story)}}) In the same year, Jack began two affairs with a couple called [[Alison (The House That Jack Built)|Alison]] and [[Miles (The House That Jack Built)|Miles]], and even attended their wedding. On the same day, Miles drowned Alison and turned himself into the police, leaving Jack to face the guilt of his role in their volatile demises. ([[PROSE]]: {{cs|The House That Jack Built (novel)}})

In [[1909]], Jack was travelling through [[Lahore]] by train with a group of soldiers under his command, when they were killed by [[Fairy|Fairies]]. Some of the soldiers had recently run over and killed one of the Fairies' [[Chosen One]]s. In revenge, the Fairies suffocated the soldiers by forcing rose petals down their throats. ([[TV]]: {{cs|Small Worlds (TV story)}}) 

In 1914, he investigated strange disappearances in [[Tiger Bay]] and discovered that the missing sailors were becoming [[Weevil]]s. He realised that this must have had something to do with [[Object 1]] and finally threw it into the Rift. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}}) Jack later left Torchwood to fight in [[World War I]]. ([[TV]]: {{cs|To the Last Man (TV story)}}, {{cs|Utopia (TV story)}})

In [[1914]], during the [[Christmas truce]], Jack was recovering in a [[hospital]] after surviving a bullet to the head. ([[COMIC]]: {{cs|The Forgotten (comic story)}})

Jack was present at [[Gallipoli]] during the [[Gallipoli campaign]]. By this point he was wearing a battered [[coat]] which had sustained several holes as a result of gunfire. He was responsible for saving the life of [[Ata]], an [[Ottoman]] soldier, while warding off a creature which fed on [[fear]] in times of [[war]]. While doing so, Jack was killed twice, first from a gunshot inflicted by Ata when he initially approached him, then again by Ottoman forces when they recovered Ata. ([[AUDIO]]: {{cs|What Have I Done? (audio story)}})

Jack fought in the [[Battle of Passchendaele]] and the [[Battle of the Somme]]. ([[TV]]: {{cs|To the Last Man (TV story)}})

In [[1918]], [[Gerald Carter]] and [[Harriet Derbyshire]] brought in [[Tommy Brockless]] to be put in suspended animation and use him as a key to fix [[time shift]]s happening then and in the 21st century. At some point after this, Jack retrieved instructions on what to do with Tommy in a box temporally locked until the Rift met the same conditions as in 1918. Jack witnessed Tommy being awakened each year to see if he "still worked". ([[TV]]: {{cs|To the Last Man (TV story)}}) Jack was witness to the [[Spanish Influenza Epidemic of 1918]], which killed 5[[%]] of the human race. ([[TV]]: {{cs|Children of Earth: Day Four (TV story)}})

In [[1919]], Jack assisted in convicting [[Roderick Simonsen]], though he was unaware of the true nature of Simonsen's crimes. ([[PROSE]]: {{cs|They Keep Killing Andy (short story)}})

In the [[1920s]], to investigate the [[Night Travellers]], Jack joined a travelling show in which he was billed as "the man who couldn't die". ([[TV]]: {{cs|From Out of the Rain (TV story)}}) In [[1924]], Jack was sent to shut [[Torchwood India]] down. During his stay in [[Delhi]], he had a brief fling with Torchwood India's leader, [[Eleanor (Golden Age)|Eleanor]]. He arranged for all their alien artefacts to be transported back to Britain ([[AUDIO]]: {{cs|Golden Age (audio story)}}) except for Object 1, which the angry Eleanor had sent to him anyway. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

In [[1927]], Jack went to [[New York City]] on a mission to stop the [[Trickster's Brigade]] from infecting [[President]] [[Franklin Delano Roosevelt|Roosevelt's]] brain with a [[Brainspawn|parasite]]. When he arrived at [[Ellis Island]], Jack met [[Angelo Colasanto]]. The two stayed in a room in New York together and had [[sex]]. Comparing Angelo to one of the Doctor's [[companion]]s, the two went to the warehouse where the parasite was being kept and killed it. As the two tried to escape, however, Jack was killed and Angelo was captured and taken to jail.

[[File:TORCHWOODx407x204913.423.jpg|thumb|left|Jack is tortured repeatedly. ([[TV]]: {{cs|Immortal Sins (TV story)}})]]
[[1928|The next year]], after Angelo got out of jail, Jack returned claiming that he had only been playing dead. Angelo didn't believe Jack, however, and assumed that Jack was the Devil. Angelo stabbed Jack and was shocked when Jack came back to life. Jack was then chained up and repeatedly killed, since people assumed that his immortality was either a [[miracle]] or a blessing. Jack then saw three men come to the room where he was chained, but he never learned who they were. Angelo decided to help Jack escape, but Jack jumped off of a building and disappeared from Angelo's life. ([[TV]]: {{cs|Immortal Sins (TV story)}})

Jack later fought in [[World War II]]. ([[TV]]: {{cs|Utopia (TV story)}}) He claimed to have been a [[prisoner of war]] on a German U-Boat for a couple of weeks, during which time he seduced a number of the submariners. ([[PROSE]]: {{cs|Plant Life (short story)}}) During the war, he met [[Estelle Cole]]. The pair became lovers and 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. ([[TV]]: {{cs|Small Worlds (TV story)}})

In the [[1950s]] Jack discovered that members of Torchwood Three were selling alien artefacts at [[auction]]s in Cardiff. To put a stop to this he flooded the market with fake artefacts, destroying the buyers' demand. ([[PROSE]]: {{cs|The Beauty of Our Weapons (short story)}})

In [[1955]], Jack was burnt to death whilst trying to save [[Hugo (Outbreak)|Hugo]] and other men infected with [[Invictus]]. He revived in a room with [[Norton Folgate]], whom he blamed for what happened. Norton eventually won him around and they had a [[sex]]ual relationship, ([[AUDIO]]: {{cs|Prodromal: Love}}) also coming up with a plan should [[Good Thinking]] ever be used again, inserting a [[trojan horse]] into Jack's personal data. ([[AUDIO]]: {{cs|Invasion: Kill}})

In [[1965]], the alien race known as [[the 456]], communicating through radio, set up a deal: Jack, with the involvement of [[Andrew Staines]], [[Ellen Hunt]] and [[Michael Sanders]], 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 them a cure for a new strain of an [[Indonesia]]n [[Influenza|flu]] that the aliens claimed would mutate and kill twenty-five million people. Jack received the assignment specifically because of his immortality, and the perception, as [[Venessa|one of the officers]] later told him, that he "didn't care." Despite his misgivings, Jack followed his orders, and delivered the children. [[Clement McDonald]], however, slipped away from the exchange, and had nightmares about Jack for the rest of his life. ([[TV]]: {{cs|Children of Earth: Day Four (TV story)}})

In the [[1970s]], Jack sported a [[moustache]]. ([[TV]]: {{cs|End of the Road (TV story)}}) He dated [[Stella Courtney]] for five weeks. ([[AUDIO]]: {{cs|The Dead Line (audio story)}})

In [[1975]], Jack and another Torchwood agent, [[Lucia Moretti]], had a daughter, [[Alice Carter|Melissa Moretti]], who aged 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 Program, 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 [[14 February]], [[1977]]; however, Jack eventually rebuilt a relationship with his daughter. Although Jack was a Torchwood agent at the time, he was still considered a freelance operative rather than a full-time employee. ([[TV]]: {{cs|Children of Earth: Day Three (TV story)}})

On several occasions during the [[1990s]], Jack visited the [[Powell Estate]] to watch Rose Tyler grow up, but did not approach her to avoid disrupting her timeline. ([[TV]]: {{cs|Utopia (TV story)}})

At some point during the 20th century, Jack found a [[Rehabilitator]] and documented it in Torchwood's archives. ([[PROSE]]: {{cs|Kaleidoscope (short story)}}) 

At another point, he briefly met the [[author]] [[Arthur Machen]] and found him to be an interesting man. Jack later revealed himself to be familiar with Machen's writing. ([[PROSE]]: {{cs|The Wrong Hands (short story)}})

Around [[Christmas]] [[1999]], Jack dropped a truck on the [[Millennium Bug]]. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

On [[1 January|New Year's Day]] [[2000]], Jack, now a full-time agent for Torchwood Three, suffered a major emotional blow when one of his colleagues, [[Alex Hopkins]], suffered a nervous breakdown and killed the entire Torchwood Three staff. Knowing Jack couldn't die, he did not attempt to kill Jack and waited for him to arrive at the Hub before committing suicide. As the only surviving member of Torchwood Three, he spent the next few years recruiting new members. ([[TV]]: {{cs|Fragments (TV story)}})

After taking over, Jack found two people the Rift had taken and later returned to Cardiff inside the vaults. He established an institution for them on [[Flat Holm]] Island, and told the careers there that they, and others that came through, were experiments gone wrong. ([[TV]]: {{cs|Adrift (TV story)}})
[[File:Jack Harkness as Sixth Doctor.jpg|thumb|left|Jack disguised as the [[Sixth Doctor]]. ([[AUDIO]]: {{cs|Piece of Mind (audio story)}})]]
Over several years Jack rebuilt his decimated organisation. He headhunted weapons expert [[Suzie Costello]] to come to Cardiff to join ([[AUDIO]]: {{cs|Moving Target (audio story)}}) and later recruited [[Toshiko Sato]] from [[UNIT]] imprisonment. ([[TV]]: {{cs|Fragments (TV story)}}) [[Sebastian Vaughan]] joined the team thanks to [[Sebastian Vaughan's father|his father]], a [[Cabinet of the United Kingdom|Cabinet]] [[minister]]. ([[AUDIO]]: {{cs|The Vigil (audio story)}})

In [[2004]], Torchwood Three shutdown an [[Ovid Industries|Ovid]] factory making duplicates of a village's population in South Wales. Suzie found Object 1 in the factory, so Jack had her phone [[Yvonne Hartman]] to pass it on to [[Torchwood One]]. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

Jack was present in the Hub on [[26 March]] [[2005]] when it was temporarily frozen in a [[time bubble]] for a day by Torchwood One's [[Rajesh Singh]] so that director Yvonne Hartman could procure a [[Drahvin scanner]] from the Hub unhindered. Yvonne observed the frozen Jack, noting this was the first time they had met, though he was unable to notice her. She commented that his photographs did not do him justice. Understanding that Jack did not work "for Queen and Country", Yvonne regarded him as a liability and "not Torchwood" and would soon after arrange for the new [[Lord Mayor of Cardiff]], [[Barry Jackson]], to inform her when [[the Doctor]] appeared in Cardiff, knowing that Jack would not. ([[AUDIO]]: {{cs|One Rule (audio story)}})

Jack met [[Owen Harper|Dr Owen Harper]] when he dealt with an [[tumour alien|alien parasite]] which had inhabited the [[brain]] of Owen's [[fiancée]] [[Katie Russell]] under the guise of a tumour before revealing itself during surgery, with Jack being forced to sedate Owen when he refused to let him recover her body before altering security footage to remove all traces of himself. Jack later went to observe, from a distance, Owen standing by Katie's [[grave]] following her [[funeral]]. He was seen by Owen, who angrily rushed towards and attacked him before breaking down in his arms. After Owen calmed down, Jack offered Owen a job with Torchwood Three, so he could save people and find purpose without Katie. Owen reluctantly accepted. ([[TV]]: {{cs|Fragments (TV story)}})

Jack's activities at the time of the [[Blaidd Drwg]] incident in Cardiff in [[September]] [[2006]], which involved Jack's younger, mortal self, ([[TV]]: {{cs|Boom Town (TV story)}}) included keeping the entire Torchwood team on lockdown in the Hub, to prevent them from seeing his younger self, and vice versa. ([[PROSE]]: {{cs|The Twilight Streets (novel)}})

After [[Torchwood One]]'s old regime was "destroyed" in the [[Battle of Canary Wharf]], Jack rebuilt and changed Torchwood's organisation. Within a few years,{{note|name="drums"}} there was a half dozen of them left. He later told the [[Tenth Doctor]] that he did this in the Doctor's honour. ([[TV]]: {{cs|The Sound of Drums (TV story)}}) In the 2000s,{{note|Episodes 1-10 of the [[Series 1 (Torchwood)|first series]] of ''[[Torchwood (series)|Torchwood]]'' are set anywhere from [[2006]]-[[2009]] as a result of [[Aliens of London dating controversy|conflicting evidence]] shown in the episodes {{cs|Ghost Machine (TV story)}}, {{cs|Greeks Bearing Gifts (TV story)}}, {{cs|Random Shoes (TV story)}}, {{cs|To the Last Man (TV story)}}, {{cs|Reset (TV story)}}, {{cs|Adrift (TV story)}}, {{cs|Fragments (TV story)}}, {{cs|Exit Wounds (TV story)}}, and {{cs|The New World (TV story)}}. As episode 10, {{cs|Out of Time (TV story)}}, is set at the end of [[December]], this means that episodes 11-13 are almost certainly set the year after episodes 1-10. The [[Ianto Jones]] flashback in {{cs|Fragments (TV story)}} itself is 21 months before that [[Series 2 (Torchwood)|series 2]] episode.}} he took in [[Ianto Jones]], a survivor of Torchwood One, after some heavy persuasion by Ianto himself. ([[TV]]: {{cs|Fragments (TV story)}}) At some point afterwards, [[Sebastian Vaughan]] was killed by a [[cortex leech]]. ([[AUDIO]]: {{cs|The Vigil (audio story)}})

During this time, Jack held on to the hope of re-establishing contact with the Doctor, who he believed could help him. At some point after Torchwood One destroyed the [[Sycorax]] ship in 2006 under orders from [[Harriet Jones|Prime Minister Harriet Jones]], ([[TV]]: {{cs|The Christmas Invasion (TV story)}}) Jack obtained [[the Tenth Doctor's hand|a severed hand]] that had fallen from the Sycorax craft and which was identified as having belonged to the Tenth Doctor. ([[TV]]: {{cs|Utopia (TV story)}}) He kept the hand in a portable container in Torchwood Three's nerve centre, the Hub, and treated it as a prized possession, much to the occasional consternation of his colleagues. ([[TV]]: {{cs|Everything Changes (TV story)}}, {{cs|Day One (TV story)}})

The team had been testing the [[resurrection gauntlet]] on a series of murders which unknown to Jack were committed by Suzie to make her understand the glove further. At a [[hospital]], he helped capture a [[Weevil]]. Police Constable [[Gwen Cooper]] began investigating Jack and followed him from the hospital to Torchwood. He showed her around the Hub, then laced a drink with [[retcon]] to make her forget about everything.

After Suzie was exposed as a serial murderer, she tried escaping by shooting Jack, but when he revived, she shot herself. Jack recruited Gwen, whose memories had resurfaced, as Torchwood's newest member. Gwen became the only person on the team who knew of Jack's immortality. ([[TV]]: {{cs|Everything Changes (TV story)}})

Jack chased after a meteorite containing the [[sex gas]] creature, where Gwen had accidentally released it. He tricked the gas creature into leaving [[Carys Fletcher]] and entering the Torchwood [[portable prison cell]]. The entity was poisoned by [[Earth]]'s atmosphere and died. ([[TV]]: {{cs|Day One (TV story)}})

As Gwen was a "beat cop", and untrained in firearms, Jack trained her to protect herself. ([[TV]]: {{cs|Day One (TV story)}}, {{cs|Ghost Machine (TV story)}})

Jack helped Gwen and Owen capture a [[quantum transducer]] [[Bernie Harris]] had been carrying. He later confiscated the alien artefacts Bernie had been trying to sell. He failed to prevent the death of [[Ed Morgan]] Gwen indirectly foresaw with the transducer. Jack then ordered the transducer locked away. ([[TV]]: {{cs|Ghost Machine (TV story)}})

Ianto had hidden the partially-[[Cyber-conversion|converted]] [[Cyberman (Pete's World)|Cyberman]] [[Lisa Hallett]] inside the Torchwood Hub. Jack and the others managed to bypass the Hub's lockdown and escape, but Ianto rushed back for his girlfriend. After Lisa had placed her brain inside the body of another human, the rest of the team had no choice but to kill her. ([[TV]]: {{cs|Cyberwoman (TV story)}}) Sometime later, Jack asked Ianto how he was after Lisa's death and took him on a Weevil hunt. ([[AUDIO]]: {{cs|Broken (audio story)}})

Jack re-encountered the same fairies that had killed his men in Lahore. He saw them kill Estelle Cole and he prevented Gwen from stopping [[Jasmine Pierce]], their new [[Chosen One]], from joining their ranks as they could have destroyed the Earth. His team turned their backs on him after this, angry at his decision. ([[TV]]: {{cs|Small Worlds (TV story)}})

Jack and Ianto worked together against an incursion of [[Scorchies]] at the Millennium Centre. Afterwards Ianto confessed he wanted to be more involved in the team and Jack promised to try to help with that. ([[AUDIO]]: {{cs|Broken (audio story)}})

The Torchwood team travelled to the [[Wales|Welsh]] countryside to investigate a series of disappearances, fearing the Rift was expanding. The [[Torchwood SUV]] was stolen by [[Brynblaidd cannibal|a group of cannibals]] that harvested travellers once every ten years. The team followed the cannibals to [[Brynblaidd|their village]]. Right as his team were captured, Jack stepped in and incapacitated the cannibals with a shotgun. The cannibals were arrested by the [[police]]. ([[TV]]: {{cs|Countrycide (TV story)}}) He asked Ianto how he was coping a few days later, as Tosh had been reporting having nightmares. ([[AUDIO]]: {{cs|Broken (audio story)}})

The Torchwood team discovered a teleporter buried in the ground for two hundred years, alongside a corpse of a soldier with his [[heart]] ripped out. An [[Arcateenian]] called [[Mary (Greeks Bearing Gifts)|Mary]] threatened Tosh's life, demanding her transporter back. Jack reprogrammed Mary's teleporter as he handed it back and she was teleported straight into the [[Sol|Sun]]. ([[TV]]: {{cs|Greeks Bearing Gifts (TV story)}}) That night he went to [[The Ferret]] to investigate disappearances and possible Rift activity and encountered Ianto in the pub. Despite Ianto's requests for him to stay away, he followed him when the barmaid Mandy took him to meet [[the Saviour]]. Jack knew what the Saviour really was and that his race were slave traders. Distressed at Mandy's betrayal, Ianto pushed him into the rift which the Saviour had opened. Ianto then regretted his decision and went to retrieve him from the camp. Afterwards they had a proper talk about what Ianto was going through and began a relationship. ([[AUDIO]]: {{cs|Broken (audio story)}})

Jack decided to investigate the conspiracy theorist [[George Wilson (The Conspiracy)|George Wilson]] who talked about [[the Committee]], as he knew that the Committee actually existed. He posed as an investigator for [[Plexus Magazine]] to attend one of Wilson's conferences where he met by accident with [[Sam Hallett]] who recognised him. He managed to get an interview from [[Kate Wilson]] with her father. He learnt about the different phases that George believed the Committee was arranging. He then spent his time looking through video footage of George learning more about him. During his research he was contacted by Sam and Jack was forced to watch Sam commit suicide. He went to Wilson to find out why Sam was killed. Jack learnt what Wilson thought he had made it all up, though Jack knew some of it was true. He found out that Kate was a member of the Committee and that they knew all about him. Kate told him that she was feeding enough information to George to make the humans believe the conspiracy and that they were doing this to make the humans complacent. He then went AWOL from Torchwood for a while to investigate them, leaving a recording for the rest of the team to explain his disappearance. ([[AUDIO]]: {{cs|The Conspiracy (audio story)}})

Jack decided to investigate [[Neil Redmond]] after learning Kate had escaped the country in one of his private's jets, learning about his doppelganger [[NJ]]. He investigated Neil's crash and traced mysterious things following the accident. Talking with Neil, he discovered that [[Eve Trent]] from [[Ovid Industries]] had supplied him with the doppelganger. He told Neil that his actions had cost a lot of people their lives. Neil detailed how he got the robot to take over his operations and his social life, but he started to resent him. Jack informed Neil that NJ was going rogue and dealing with terrorists. He later met with NJ who tried to seduce him and succeeded. After having sex with NJ he told Neil to shut him down but this didn't work. NJ attacked Jack after this and killed him. After Jack came back to life he managed to destroy NJ, but not before NJ confirmed that he was made by the Committee and that the Committee weren't invading the Earth, they had been invited. Jack decided he couldn't do this alone and rejoined Torchwood. ([[AUDIO]]: {{cs|Uncanny Valley (audio story)}})

While investigating a murder case with Suzie's involvement, Gwen revived Suzie using the resurrection gauntlet, and started having her life drained by the constant link the gauntlet maintained between them. After shooting her achieved nothing, Jack ordered Tosh to destroy the gauntlet, killing Suzie and saving Gwen's life. ([[TV]]: {{cs|They Keep Killing Suzie (TV story)}})

When Gwen was investigating the death of [[Eugene Jones]], Jack tried to make her stop but she refused. Jack was later present when Eugene reappeared to save Gwen's life from a speeding car. Jack thanked Gwen for not giving up on Eugene. ([[TV]]: {{cs|Random Shoes (TV story)}})

At some point in 2007, Jack was kidnapped by [[the Three Families]]. Gwen came looking for him and was also captured. They were transported to [[Chernobyl]], where the Families extracted blood samples from Jack, and used retcon gas to remove his and Gwen's memories of the event. This event would prove significant later. ([[TV]]: {{cs|Miracle Day (TV story)}}, [[WC]]: {{cs|Web of Lies (webcast)}})

Jack saw [[John Ellis]], [[Emma-Louise Cowell]] and [[Diane Holmes]] come through the Rift from [[1953]] Earth in the ''[[Sky Gypsy]]''. He befriended John, as he was also a man out of his own time. As John had nothing left to live for, he committed [[suicide]]. Unable to convince John to continue living, Jack held his hand as the [[car]] fumes overwhelmed John. ([[TV]]: {{cs|Out of Time (TV story)}})

Jack shut down a [[Weevil Fight Club]], freed the Weevil captive there and saved Owen's life. Owen chastised Jack for saving him, saying that he felt "totally at peace". ([[TV]]: {{cs|Combat (TV story)}})

Tosh and Jack investigated music from the [[1940s]] playing from [[the Ritz]]. The Rift brought them back to 1941, where they met Jack's namesake. Jack bonded with the real Jack over war stories and inadvertently complicated his relationship with [[Nancy Floyd]]. The two Jacks had a brief romance. Owen opened the Rift with the [[Rift Manipulator]] to return Jack and Tosh to the [[21st century]]. ([[TV]]: {{cs|Captain Jack Harkness (TV story)}})

The opening of the Rift brought diseases and people across time and space so Jack felt forced to dismiss Owen. Owen later returned and shot Jack; through [[Bilis Manger]]'s manipulations, Owen re-opened the Rift to send everything back. Jack resurrected and the rest of his team learnt of his immortality.

After the Rift was opened, Jack was forced to confront [[Abaddon]]. Abbadon was destroyed while attempting to leech Jack's life, though the exertion resulted in Jack remaining dead for days, his immortality apparently unable to save him. He was brought back to life after a [[kiss]] from Gwen.

A short while 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. ([[TV]]: {{cs|End of Days (TV story)}})

=== Reunion with the Doctor ===
{{Section cleanup|Character pages are not the place for plot summaries. A brief 2-3 sentence summary per story is all that is needed.}}
Having heard the TARDIS, Jack left the Hub with the Doctor's hand in a backpack. Rushing to where it was parked, he managed to jump onto the ship before it dematerialised, clinging on as it travelled through the time vortex to the year [[100000000000000|100,000,000,000,000]]. The Doctor and Jack had an awkward reunion, owing both to the Doctor's [[regeneration]] into his [[Tenth Doctor|tenth incarnation]] since they last met and the fact the Ninth Doctor had abandoned him on Satellite Five. Before long the Doctor admitted that he had run from Jack because his unique nature as a living temporal anomaly made the Time Lord physically uncomfortable when near him — even ''looking'' at Jack was an effort. Jack made the happy discovery, though, that Rose had not been killed in the [[Battle of Canary Wharf]] as he had believed. They met and helped [[Yana|Professor Yana]] to repair a [[Utopia Project rocket|spaceship]] in order to help the last humans in the universe reach [[Utopia (Utopia)|Utopia]]. After Yana became {{jacobi}}, who regenerated into {{simm|n=a new body}} and took off in the TARDIS with the Doctor's hand still inside, Jack, the Doctor and the Doctor's companion [[Martha Jones]] were left stranded at the end of the universe to be killed by the [[Futurekind]]. ([[TV]]: {{cs|Utopia (TV story)}})
[[File:31ll.jpg|thumb|right|Jack, Martha and the Doctor in hiding. ([[TV]]: {{cs|The Sound of Drums (TV story)}})]]

After the Doctor fixed [[Jack Harkness' vortex manipulator|Jack's vortex manipulator]], the trio used it to escape the Futurekind and travel back to the 2000s,{{note|name="drums"}} where they discovered the Master, using the alias "Harold Saxon", had been elected [[Great Britain]]'s [[Prime Minister]]. He framed them for terrorism, planting explosives in Martha's flat. He also made sure that Jack couldn't get help from his Torchwood team by sending them to the [[Himalayas]] "on a wild goose chase". With nowhere to go, Jack, the Doctor and Martha went on the run.

On board the Master's airship, the ''[[Valiant (aircraft carrier)|Valiant]]'', the Doctor discovered his TARDIS had been turned into a [[paradox machine]]. After failing to foil the Master's plot, the Master summoned the [[Toclafane]], whom he ordered to assassinate [[President of the United States|US President]] [[Arthur Winters]], attack the Earth, and decimate the population. He then killed Jack and aged the Doctor with his [[laser screwdriver]]. ([[TV]]: {{cs|The Sound of Drums (TV story)}}) As the Toclafane began slaughtering the population, Jack, realising they couldn't stop the Master, told Martha to escape using his vortex manipulator. ([[TV]]: {{cs|The Sound of Drums (TV story)}}, {{cs|Last of the Time Lords (TV story)}})

Being kept prisoner aboard the ''Valiant'' for [[The Year That Never Was|a year]], Jack, the Doctor and the Jones family witnessed the Master and the Toclafane devastate Earth's civilisations and reduce the human race to camps of survivors, and suffered at his hands themselves. Bound in chains aboard the Valiant, the thing that kept Jack going during the year of hell was the thought of getting back to his Torchwood team.

When Martha allowed herself to be taken to the Master, she and the Doctor revealed their plan; using the Archangel Network, the Doctor harnessed the psychic energy of humanity's hope, as Martha had spent a year travelling the world telling humanity about his importance to them. On the Doctor's orders, Jack destroyed the paradox machine keeping the Toclafane in the present, undoing the entire year; Earth was restored as time resumed for everyone else right after the President was killed, but those on the ''Valiant'' retained their memories due to being at the "eye of the storm". After the Master's death, the Doctor offered Jack the opportunity to end his long exile on Earth and join him in the TARDIS, but out of loyalty to his Torchwood team, he decided to stay in Cardiff.

Jack returned to Torchwood and the team, while they were on a mission in the 2000s,{{note|The [[Series 2 (Torchwood)|second series]] of ''[[Torchwood (series)|Torchwood]]'' is set anywhere from [[2007]]-[[2010]] as a result of [[Aliens of London dating controversy|conflicting evidence]] shown in the episodes {{cs|Ghost Machine (TV story)}}, {{cs|Greeks Bearing Gifts (TV story)}}, {{cs|Random Shoes (TV story)}}, {{cs|To the Last Man (TV story)}}, {{cs|Reset (TV story)}}, {{cs|Adrift (TV story)}}, {{cs|Fragments (TV story)}}, {{cs|Exit Wounds (TV story)}}, and {{cs|The New World (TV story)}}, as well as {{cs|Meat (TV story)}} placing the series about a year after the start of [[Series 1 (Torchwood)|series 1]].}} saving the life of a woman being menaced by a [[Blowfish (Kiss Kiss, Bang Bang)|Blowfish]].

He quickly had yet another visit from the past, this time even further back; Jack was reunited with Captain John Hart from his [[Time Agent]] days, who had come through the Rift searching for some canisters that had also come through. Captain John told Torchwood that they contained radioactive bombs. John tricked Jack, pushing him off the top of an office building and taking the canister. Jack caught up with John, but the contents of the canisters were actually components of a bomb that latched onto the [[DNA]] of [[hologram woman|the owner of the canisters']] murderer. Jack confused the bomb by injecting John with the DNA of the Torchwood team and safely disposed of it. Jack then asked John to leave. As he did so, he told Jack that he had found Gray. ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}})

Torchwood took in [[Beth Halloran]] on suspicion over the deaths of two burglars. Jack ordered a [[mind probe]] on her, and her true identity, the [[sleeper agent]] [[Kayehla Janees]], surfaced. Once Tosh deactivated the link, an advance guard of [[Cell 114]] attacked Cardiff. Jack and Gwen stopped "[[David (Sleeper)|David]]" from attacking a stockpile of nuclear warheads. Before David committed suicide, he told Jack the rest of Cell 114 had already arrived on Earth and factored Torchwood into their plans. Rather than let her sleeper agent form take over, Beth pretended to threaten Gwen and Torchwood killed her. ([[TV]]: {{cs|Sleeper (TV story)}})

Jack and Ianto tracked a [[Cell 114]] signal to [[Serenity Plaza]] and went undercover to track the sleeper agent. Pretending to be an idyllic couple, Jack went off to work each day returning to the hub, whilst Ianto stayed at home. When [[Mary (Serenity)|Mary]] thought Jack was attracted to her husband [[Bob (Serenity)|Bob]] he played along. Once the sleepers had activated, they found their control centre and Jack devised a way to completely wipe out Cell 114. ([[AUDIO]]: {{cs|Serenity (audio story)}}) 

When Ianto discovered an [[Artefact (The Beauty of Our Weapons)|alien artefact]] was missing from the archive, Gwen and Tosh tracked it down to a [[Arkanovitch Hotel|Cardiff hotel]]. When Jack arrived he recognised the artefact as a [[nuclear bomb]], and proposed the team return to the hotel later on, to steal the artefact and cast it into the Rift. ([[PROSE]]: {{cs|The Beauty of Our Weapons (short story)}}) 

Jack reawakened Tommy Brockless for the last time. Time shifts at [[St Teilo's Hospital]] started occurring and Jack's instructions to send Tommy and Toshiko back opened. Jack gave Tommy a small [[Rift Manipulator]] in order to close the time shifts. Toshiko then projected an image of herself to Tommy to tell him how to use the "key". ([[TV]]: {{cs|To the Last Man (TV story)}})

Gwen's [[fiancé]] [[Rhys Williams]] discovered the true nature of Gwen's job. Jack gave Rhys a brief tour at Torchwood and used his position as a transport manager to sneak into [[Harries & Harries]]. [[Cash Cow|An alien]] that could replenish its cells indefinitely was being mutilated there so its [[meat]] could be sold. Jack saw Owen mercy kill the creature and felt sorry for it. Torchwood then had its workers retconned and the alien incinerated. Jack asked Gwen to give Rhys retcon, but she refused. ([[TV]]: {{cs|Meat (TV story)}})

The memory-altering creature [[Adam Smith]] altered Torchwood Three's memories, making them think he had been a team member for years. After doing this, Jack's memories of Gray and his father resurfaced. Jack realised that all the memories of Adam were false and that Adam's files only dated back 48 hours. Torchwood Three took retcon and erased all trace of Adam's existence on file. ([[TV]]: {{cs|Adam (TV story)}})

Jack invited Martha onto the team to investigate [[the Pharm]], a medical organisation that could cure diseases thought incurable. He ordered Toshiko to close the Pharm down once he learnt of their mistreatment of humans and aliens alike, but the Pharm's manager, [[Aaron Copley]], shot Owen and then Jack shot him. ([[TV]]: {{cs|Reset (TV story)}})
[[File:Jack and owen bond.jpg|thumb|Jack and Owen commiserate over immortality. ([[TV]]: {{cs|Dead Man Walking (TV story)}})]]
Unwilling to accept the loss of another teammate, Jack tracked down the other resurrection gauntlet and brought back Owen. The attempt, though successful, left Owen unable to digest food, sleep, or enjoy sex. In addition, the glove released an extradimensional alien, [[Duroc]], the embodiment of death. Owen saved the day by using his new condition to stifle the needs of the entity, but still expressed a deep resentment towards Jack. ([[TV]]: {{cs|Dead Man Walking (TV story)}})

A regretful Jack was forced to temporarily relieve Owen until he could acclimatise. Jack later had Owen retrieve [[the Pulse]] from an ailing [[Henry Parker]]. Owen became medical officer again after Martha had taken over for Owen to acclimatise, and Jack [[kiss]]ed Martha goodbye. ([[TV]]: {{cs|A Day in the Death (TV story)}})

Gwen was impregnated by a [[Nostrovite]] Jack had killed. She decided against postponing her wedding to Rhys. The biological mother, "[[Carrie (Something Borrowed)|Carrie]]", tried forcibly taking her unborn child from Gwen's womb and Jack was forced to stop the wedding. Rhys killed the child that was killing Gwen with the [[singularity scalpel]], while Jack killed the Nostrovite mother. The wedding proceeded and Jack put retcon inside the wedding guests' drinks. ([[TV]]: {{cs|Something Borrowed (TV story)}})

Jack, feeling stuck on Earth, met [[Val Ross]] and attended some of the [[lecture]]s at the [[Church of the Outsiders]]. However, he turned against them after [[Davey Russell]]'s [[suicide]], manipulating Val into spreading [[footage]] of his [[resurrection]] and turning the Church into a laughing stock. He also saved Cardiff by telling [[Andromeda Ross]] that nobody cared about the message she sent through [[the Rift]]. ([[AUDIO]]: {{cs|Believe (audio story)}})

The Night Travellers escaped from a reel of film playing inside the [[Electro]] and took the last breaths of people in Cardiff. As more of the Travellers began to leave, Jack captured the Travellers, which were made from the same material as the film, onto a camera and destroyed the negatives by exposing them to light. Before he was destroyed, the [[Ghostmaker]] threw the flask containing the breaths and all but one of the victims died. ([[TV]]: {{cs|From Out of the Rain (TV story)}})

Jack warned Gwen not to investigate the disappearance of [[Jonah Bevan]], who unknown to Gwen had been taken away by the Rift. Ianto gave Gwen a GPS that pointed her towards Flat Holm and she found Jonah was inside, forty years older. Jack explained to Gwen what had happened to those taken to Flat Holm. Despite his protests, Gwen showed [[Nikki Bevan|Nikki]] her ill son and how he screamed for most of each day. ([[TV]]: {{cs|Adrift (TV story)}})

Jack's team came under further pressure when Captain John Hart returned, laying bombs within a warehouse in an attempt to kill all of the Torchwood Three team. This failed and Jack found a message from John on [[Jack Harkness' vortex manipulator|his vortex manipulator]], which included an appearance by Gray. 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. ([[TV]]: {{cs|Fragments (TV story)}})

On meeting John again, Jack was killed before being chained up and made to listen whilst John explained his predicament. Jack's rogue partner then detonated strategically placed bombs in and around Cardiff, obliterating the city before abducting Jack and taking both of them back through time to Cardiff in [[27]] AD.

[[File:TW Exit Wounds Jack 27ad.jpg|left|thumb|Jack in [[27]] AD. ([[TV]]: {{cs|Exit Wounds (TV story)}})]]
Here, Jack discovered that John was being manipulated by Gray, who marked his return by stabbing Jack in cold blood. Gray then forced John to bury Jack alive, twenty feet beneath what would become Cardiff. Gray, transformed into a merciless, sadistic beast by a lifetime of horrific torture, 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. Before burying Jack, John, now 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 Torchwood in [[1901]], who had picked up the signal of John's ring. 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 107 years. Despite being baffled, the two granted him this request.

Jack awoke again inside Torchwood Three concurrent to Gray's mayhem – just in time to prevent Gray from finishing off Toshiko with a bullet. Despite Gray's own unwillingness to absolve him, Jack forgave his brother of his trespasses. 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 parted ways on better terms, with John travelling the world of the 21st century, determined to find out why Jack found the time period so interesting. Torchwood Three continued on, reduced to Jack, Ianto and Gwen. ([[TV]]: {{cs|Exit Wounds (TV story)}})

Disappearing from Torchwood for a while, Jack agreed with [[Jonty (Expectant)|Jonty]] to be a surrogate for the next leader of the [[Yalnix Empire]], hoping to make up for the recent deaths by creating a new life. He returned to Earth heavily pregnant, with Jonty his midwife, to Ianto's shock. He started to get very emotional due to the hormones which coursed through his body, but attempted to keep going with his duties for Torchwood including hunting Weevils. Ianto eventually booked him into a spa to wait out the rest of his pregnancy. At the Spa the rest of the clients started acting strangely, which freaked out both Jonty and Jack, fearing it was the Yalnix's enemies. They later realised that this was due to the influence of [[Junior (Expectant)|Junior]]. Ianto saved them and Jack was transported to the birthing ship. ([[AUDIO]]: {{cs|Expectant (audio story)}})

Not long after Owen and Tosh's deaths, Martha phoned Jack for help at the [[CERN]]'s [[Large Hadron Collider]]. He, Ianto and Gwen flew to [[Switzerland]] and met up with Martha. They investigated twelve accidents and found [[Neutron eater|a creature]] that fed on neutrons was responsible. ([[AUDIO]]: {{cs|Lost Souls (audio story)}})

==== Dalek invasion of Earth ====
Later, when the Earth was relocated by the [[Dalek]]s to the [[Medusa Cascade]] in the 2000s,{{note|The present day of ''[[Doctor Who]]''{{'}}s [[Series 4 (Doctor Who)|fourth series]] is [[Aliens of London dating controversy|not consistently dated]], with [[TV]]: {{cs|The Fires of Pompeii (TV story)}}, [[TV]]: {{cs|The Waters of Mars (TV story)}}, and [[AUDIO]]: {{cs|SOS (audio story)}} setting the present of the 13 regular episodes in [[2008]] (heavily implied by [[TV]]: {{cs|The Star Beast (TV story)}} and [[TV]]: {{cs|The Giggle (TV story)}} as well), and [[PROSE]]: {{cs|Beautiful Chaos (novel)}} setting them in about [[April]] to [[June]] [[2009]].}} [[Harriet Jones]], a former Prime Minister and acquaintance of the [[Tenth Doctor]], contacted Torchwood and [[Children of Time|other allies of the Doctor]] via the [[Sub-Wave Network]]. After receiving vital information from Martha that allowed him to reactivate [[Jack Harkness' vortex manipulator|his vortex manipulator]], Jack [[teleport]]ed to the Doctor's side just as a Dalek shot him. ([[TV]]: {{cs|The Stolen Earth (TV story)}})

[[File:61.jpg|thumb|left|Jack is killed by the [[Supreme Dalek (The Stolen Earth)|Supreme Dalek]]. ([[TV]]: {{cs|Journey's End (TV story)}})]]
Subsequently, after the Doctor's abortive regeneration, Jack boarded the [[Crucible]] and surrendered to the Dalek forces. After the TARDIS was supposedly destroyed, he attempted to shoot the [[Supreme Dalek (The Stolen Earth)|Supreme Dalek]] in anger and was promptly "exterminated". Reviving before his body could be incinerated, he subsequently burrowed into the Crucible and linked up with [[Sarah Jane Smith]], [[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 transported to [[Davros]]' chamber instead.

When [[Donna Noble]] disabled the Daleks, the Supreme Dalek descended into the vault and destroyed the Magnetron that was bringing the [[stolen planets]] back to their rightful positions, leaving Earth behind. Jack blasted the Supreme Dalek again, this time successfully destroying it.

The [[Meta-Crisis Tenth Doctor]] finished off the Daleks, destroying the Crucible. Jack 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. ([[TV]]: {{cs|Journey's End (TV story)}})

Jack made a series of tutorial videos about [[Adipose]], [[Pyrovile]]s, [[Ood]], [[Sontaran]]s, [[Slitheen family|Slitheen]], [[Hath]], [[Vespiform]]s, [[Vashta Nerada]], [[Judoon]], the [[Midnight entity]], [[the Trickster's Brigade]], Daleks, Davros, festive [[alien]]s and [[Cyberman|Cybermen]] in the Torchwood Three Hub. These were confiscated by [[UNIT]] and were made top-secret footage. ([[WC]]: {{cs|Captain Jack's Monster Files}})

Following a cannibalistic massacre on a yacht in [[Cardiff Bay]], Jack and Ianto found themselves [[zombie]]-hunting in [[Trowbridge]]. As Jack captured a zombie, which he nicknamed [[Mildred (Bay of the Dead)|Mildred]], Ianto saved mother-to-be [[Sarah Thomas]], along with her injured husband, [[Trystan Thomas]], who were under attack from a quartet of "[[Search unit|zombies]]". While putting Mildred in the boot of the SUV, Jack was attacked and knocked unconscious by a zombie which jumped out from beneath the vehicle. He later awoke in the autopsy room, and travelled with Ianto to [[St Helen's Hospital]]. There, they met up with Gwen and Rhys, and found that [[Leet (Bay of the Dead)|Leet]] - a [[Dellacoi]] - had created the zombies to search for his [[life-shell]] and control over [[Search unit|the creatures]] had passed to [[Oscar Phillips (Bay of the Dead)|Oscar Phillips]], a coma patient. As Oscar ran at the hospital window, Jack held Gwen back from saving him. Oscar fell to his death, relinquishing his control over the zombies. Following Oscar's funeral, Jack went with Gwen to place [[snowdrop]]s on Oscar's grave. ([[PROSE]]: {{cs|Bay of the Dead (novel)}})

While trying to locate an [[Torrosett 51 binary heat-cannon|alien weapon]], Jack and Gwen discovered a parasitic [[Czisch|alien baby]]. Their actions caused the baby to unlatch from [[Pam Feerce|its host]], and the host then killed herself along with the baby. ([[PROSE]]: {{cs|The Wrong Hands (short story)}}) The [[Alien father (Virus)|baby's father]] then came after Torchwood, infecting Jack and Gwen with the [[Kagawa Virus]]. Jack and Gwen remained comatose for almost a full day while Ianto searched for an [[antidote]]. ([[PROSE]]: {{cs|Virus (short story)}})

Jack, Ianto, Gwen and [[Andy Davidson]] helped a confused girl named [[Freda]] who had been sent to [[2009]] by Torchwood representatives in [[2069]] to escape social prejudice against [[Ghostie]]s. ([[AUDIO]]: {{cs|Asylum (audio story)}})

Jack's past, once again, came back to haunt him when he, Gwen and Ianto began investigating visions at [[Ravenhall Manor]], which Jack had done in 1902. He re-encountered the creature that was responsible for creating the visions, and after being reunited with a trapped Gwen and Ianto, he destroyed the house. ([[COMIC]]: {{cs|Hell House (comic story)}})

Investigating an alien energy field, Jack, Gwen and Ianto travelled to [[Delhi]], [[India]], where Jack was surprised to discover that [[Torchwood India]] had maintained its existence by using a [[time store]] to remain frozen in time. Horrified at [[Eleanor (Golden Age)|Eleanor's]] plan to turn the entire Earth back to [[1924]], Jack destroyed the time store and Torchwood India. ([[AUDIO]]: {{cs|Golden Age (audio story)}})

Torchwood Three combated a mysterious force that put people into coma-like trances after they answered the phone. ([[AUDIO]]: {{cs|The Dead Line (audio story)}})

After Rhys' uncle, [[Bryn Williams]] died in the 2000s,{{note|The first two episodes of ''[[Torchwood: The Lost Files]]'' are supposedly set no earlier than [[2011]], as [[Joanna Carew]] was born in [[1930]] and is 81 years old by the time of {{cs|The Devil and Miss Carew (audio story)}}, and dialogue places {{cs|Submission (audio story)}} "more than 50 years" after the successful return of the ''[[Trieste (submarine)|Trieste]]''{{'}}s crew from the depths of the [[Mariana Trench]] in [[1960]].

She was a woman in her eighties who was fit and at work after being on her deathbed not long before. Carew worked with [[Fitzroy (The Devil and Miss Carew)|Fitzroy]] to destroy all electricity on Earth, but was stopped. ([[AUDIO]]: {{cs|The Devil and Miss Carew (audio story)}})

Torchwood Three, working in cooperation with [[UNIT]], tracked a distress signal to the [[Mariana Trench]] and discovered [[Sam Doyle]] of the [[Guernica (submarine)|Guernica]] who hadn't aged in fifty years. The team defeated [[Parasite (Submission)|the entity]] possessing him which later entered [[Carlie Roberts]]. ([[AUDIO]]: {{cs|Submission (audio story)}})

In [[2009]], Jack recognised [[Invictus]] when he met the infected [[Luke Palmer]]. He [[quantum seal]]ed the Hub to prevent himself from killing Gwen and Ianto, but the latter was still inside. ([[AUDIO]]: {{cs|Incubation: Know}}) He had [[hallucination]]s about what happened in [[1955]] and tried to kill Ianto, only failing because he entered Stage 4 and died, his data being uploaded to the [[Data Core (Outbreak)|Data Core]].

([[AUDIO]]: {{cs|Invasion: Kill}})

Jack and Ianto played with a dog, [[Untitled (The Torchwood Archive)|Untitled]], whilst being observed by [[Roy (Ghost Mission)|Roy]]. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

Jack had kept the medical officer position vacant in the hopes of Martha deciding to join, but ultimately she went freelance instead. ([[AUDIO]]: {{cs|Dissected (audio story)}})

==== Fighting the 456 ====
Also in September, Jack's past returned to haunt him when the 456, in need of more subjects for their drug production, once more contacted humanity by using the children of Earth as a collective mouthpiece. The [[British government]], fearing that the secret of the deal would come out, assigned [[John Frobisher]] to deal with the situation. Frobisher, knowing Jack's role as part of the team which had negotiated with the 456, reluctantly ordered Jack's assassination. Speculating, incorrectly, that the Hub had special properties which enabled Jack's regenerative abilities, Frobisher insisted on the complete destruction of the Hub, along with Jack, who was already attempting to investigate by seeking to examine his grandson [[Steven Carter|Steven]].

The government, through a ruse involving their agent [[Rupesh Patanjali]], killed Jack and planted a bomb inside his body before he revived. When Jack, unsuspecting, returned to the Hub, the bomb detonated, destroying both Jack's body and the Hub, but not before Jack managed to evacuate Gwen and Ianto. ([[TV]]: {{cs|Children of Earth: Day One (TV story)}})

[[File:Jack Harkness chained burnt CoE Day2.jpg|thumb|Jack chained up, after the effect of the explosion inside him. ([[TV]]: {{cs|Children of Earth: Day Two (TV story)}})]]
A covert ops team conveyed Jack's scattered remains to a holding facility, where he slowly regenerated his body and returned to life. When Frobisher's chief of operations in the task force realised that destroying the Hub had not rendered Jack mortal, she had him encased in concrete. Gwen and Ianto, however, had not been idle, and with the help of [[Rhys Williams|Rhys]] and Ianto's sister [[Rhiannon Davies|Rhiannon]], they infiltrated the facility and rescued him. ([[TV]]: {{cs|Children of Earth: Day Two (TV story)}})

With Ianto's knowledge of Torchwood One's old infrastructure and a little criminal mischief orchestrated by Gwen, Jack headquartered his team inside a former Torchwood facility. Gwen arranged for the protection of former 456 victim Clem MacDonald by bringing him to "Hub 2," as Rhys came to call it. Jack himself tracked down Frobisher and warned him to call off the assassination, or the 1965 incident would be disclosed. However, Frobisher countered with a new bombshell: Johnson's team had taken Jack's daughter Alice and grandson Steven hostage in order to ensure Jack's silence in the plans to negotiate terms with the 456. ([[TV]]: {{cs|Children of Earth: Day Three (TV story)}})
Jack, Gwen, Ianto and Rhys retaliated by persuading [[Lois Habiba]] to collect incriminating evidence against the entire [[Cabinet of the United Kingdom|Cabinet]] regarding the new terms, then threatening full disclosure unless Torchwood was allowed access to the 456. Storming into [[Thames House]] to confront the aliens, Jack and Ianto promised a "fight to the death." In response, the 456 released a virus into the Thames House, killing all inside. Among the victims was Ianto, who died in Jack's arms. ([[TV]]: {{cs|Children of Earth: Day Four (TV story)}})

A tearful Captain Jack surrendered to the authorities, blaming himself for Ianto's death. He instructed Gwen to have Rhys surrender himself as well, and arranged for the couple to return to Cardiff, with instructions to inform Rhiannon of her brother's death and to see to the needs of her family.

As the world governments began capitulating to the demands of the 456, and began rounding up children by the millions, Jack found himself sprung from prison by a surprise ally — Agent Johnson, who had become disillusioned and convinced by Alice to take a stand. With the aid of Johnson and Mr [[Dekker]], who had managed to escape the massacre at Thames House, Jack devised a way to defeat the 456 using a [[reconstitution wave]] of a similar wavelength to that the 456 had used to kill Clem, using the children as one vast transmitter. There was one major catch: in order for it to work, the wave needed to be channelled through one child, for whom the force of the transmission would be deadly. Only one child was available to serve as the "transmitter." Ignoring his daughter's screams and protests, Jack used his own grandson, Steven, as the prime transmitter. The plan succeeded, and the 456 were violently ejected from Earth. However, Steven died as a result, and Alice severed all contact with Jack, walking away without speaking a word. ([[TV]]: {{cs|Children of Earth: Day Five (TV story)}})

Jack was officially declared dead as a result of the [[456 Regulation]]. ([[TV]]: {{cs|The New World (TV story)}})

=== Leaving Torchwood Three ===
In [[October]] 2009, Jack was present in Cardiff when Suzie Costello was resurrected for the second time. He informed Suzie over the phone that he was "coming for her". He later observed her final death from the top of the Millennium Centre. ([[PROSE]]: {{cs|Long Time Dead (novel)}})

Jack then went on to travel the world. He did not find it enough to rid himself of his guilt. After six months he returned to Cardiff to destroy [[the House of the Dead]], believing it would seal the Rift forever. He encountered the ghost of Ianto Jones at the house, and the couple finally confessed their love to each other for the first and last time. Ianto refused to let Jack sacrifice himself to seal the Rift and tricked him into leaving. Jack watched as the House of the Dead was destroyed with the ghost of Ianto unable to leave. ([[AUDIO]]: {{cs|The House of the Dead (audio story)}}) Shortly after this event, Jack decided to leave Earth. After saying goodbye to Gwen and Rhys, he used [[Jack Harkness' vortex manipulator|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 [[teleport]]ed off into space. ([[TV]]: {{cs|Children of Earth: Day Five (TV story)}})

[[File:The-end-of-time-73.jpg|thumb|left|Jack in a [[Zaggit Zagoo bar|bar]]. ([[TV]]: {{cs|The End of Time (TV story)}})]]
Some time later, Jack was drowning his sorrows in [[Zaggit Zagoo bar|a bar]] surrounded by various alien species, when a barman handed him a folded piece of paper which indicated that someone's name was [[Alonso Frame|Alonso]]. Looking up, he saw the Tenth Doctor staring back, before gesturing towards the man approaching the bar. Seizing the opportunity, Jack addressed Alonso by his first name and told him that he was psychic when asked how he knew him. The Doctor left as Jack continued to flirt with Alonso. ([[TV]]: {{cs|The End of Time (TV story)}})

Their evening was soon interrupted as the [[space station (One Enchanted Evening)|space station]] they were on was attacked by the forces of [[Mother Nothing]], a giant [[cannibal]] [[beetle]] that sought its [[diamond engine]]. Ultimately, with Alonso Frame's assistance, Jack was able to defeat Mother Nothing and resolve the crisis. It was at this point that Jack learnt that Alonso had met the Doctor as well. Left with only a single operable [[escape pod]] between the two of them, Jack was knocked out by the [[midshipman]] who, unaware of his immortality, sent him out to safety. Awaking in his pod, Jack, presuming Alonso [[dead]], was enraged to know he sacrificed himself in vain only to learn that he had managed to repair a pod for himself and survive. However, Jack and Alonso were separated when a [[meteor shower]] sent them on different paths. ([[AUDIO]]: {{cs|One Enchanted Evening (audio story)}})

=== Mortal once again ===
[[File:Jack saves gwen.jpg|thumb|Jack reunites with Gwen. ([[TV]]: {{cs|The New World (TV story)}})]]
Jack returned to planet Earth when the word "Torchwood" was emailed all around the world, coinciding with the start of the [[Miracle Day]] phenomenon. He used malware to expunge evidence of Torchwood from the Internet, and went to the CIA hard copy records to clear the last of the information. There he encountered [[Central Intelligence Agency|CIA agent]] [[Esther Drummond]], on whom he used [[Retcon]]. Jack used the alias "Owen Harper" while he gathered more information; he learned that the Miracle had given humans a version of his immortality, once seeing a severed head continue to live but unable to reform or heal. Jack also discovered that on Miracle Day, he lost his immortality, or perhaps just his instant healing ability as he kept minor wounds that normally would have healed in a day for him (from the explosion at the CIA Archives). He followed [[Rex Matheson]], also CIA, to Wales to protect Gwen. There, they fought off assassins. Despite planning to investigate the Miracle with Gwen, Matheson extradited them to the United States against their will. ([[TV]]: {{cs|The New World (TV story)}})

Once the pair were forced onto a plane headed for America, Rex confiscated Jack's vortex manipulator and handcuffed him to his seat. Hearing his manipulator beeping, Jack told Rex he had low sodium levels. Jack asked for a Coke, but was poisoned with arsenic by corrupt CIA agent [[Lyn Peterfield]]. He was saved by Rex and Gwen with the help of [[Vera Juarez|Dr Vera Juarez]] via phone call. Upon arrival at the airport, Rex freed Jack (along with Gwen) to fight the now corrupt CIA who wished to frame and dispose of them. After Lyn's neck was broken and the guards knocked out, the three boarded the car of Rex's fellow ex-agent, Esther. They left the airport after Jack briefly met the doctor who had saved his life. ([[TV]]: {{cs|Rendition (TV story)}})

Jack took command of the now ex-CIA agents with Gwen to form a [[Torchwood (team)|new Torchwood team]]. They began stealing materials needed for operations again, and purchasing necessities with his [[cash machine|ATM]] card, which had a large amount to spend. Soon coming into possession of the phone of [[Brian Friedkin]], the CIA director who had given the orders to eliminate Torchwood, Jack led the team to a warehouse owned by [[PhiCorp]]. Inside was a stockpile of painkiller drugs, indicating that they knew "Miracle Day" would happen. Seemingly out of character, Jack decided to take the night off from his usual persistence in solving a mystery and had [[Sex|a one-night stand]] with a bartender. The following night, Jack confronted PhiCorp's new public face, [[Oswald Danes]], and got him to admit his true feelings about his crime. Jack realised that Danes wished desperately for death. He was tossed out by Danes' guards, who took the recording he made of his conversation with Oswald. ([[TV]]: {{cs|Dead of Night (TV story)}})

Jack went to [[Los Angeles]] with the new Torchwood team to infiltrate a PhiCorp facility there. Unknown to him, they were followed by an [[The Gentleman (Escape to LA)|assassin]] with orders to kill Jack. After arriving in LA, Jack and Gwen tricked [[Nicolas Frumkin]] into giving them access to the PhiCorp base. However, the assassin also gained access, and followed Jack and Gwen there. Inside the building, the assassin tied up Jack and Gwen, and informed them he had been ordered to kill Jack. However, the assassin was fascinated that Jack was the only mortal man left, and did not want to kill him. After informing Jack that something that he did in the past was involved, the assassin threatened to cut Gwen's throat. Before he could carry out his threat, he was shot in the throat by Rex. This earned Jack's anger as the assassin could have filled in the blanks about the new enemy they were facing. ([[TV]]: {{cs|Escape to LA (TV story)}})

After the new [[categories of life]] were released and the [[overflow camp]]s were opened, Gwen returned to Wales to free her father from one and Dr. Vera Juarez came to LA to join Torchwood. Rex, Vera, and Esther decided to infiltrate [[San Pedro Overflow Camp|an overflow camp]]. As he was recognised easily by anyone working for this new enemy, Jack couldn't go. Learning Oswald Danes was to give a speech at the [[Miracle Rally]], Jack sneaked in and tried persuading Danes to read a speech he wrote, revealing PhiCorp knew of the Miracle beforehand, instead of the speech that [[Jilly Kitzinger]] had written. If Danes read his speech, Jack promised that when the Miracle ended, he would help him die as he desperately wished. Much to his disappointment, Jack watched as Oswald took parts from both speeches to make his own, saying humanity had evolved into ever-lasting angels. ([[TV]]: {{cs|The Categories of Life (TV story)}})

Jack gained access to [[Stuart Owens]]' email and found out that he was having an extra-marital affair with [[Janet Tanner]] and that he planned to transfer her. Jack met Janet in a bar and persuaded her to help him meet Owens. Janet pretended to have been kidnapped over the phone, while Jack spoke with Stuart in a restaurant. Stuart explained that despite his position in PhiCorp, he did not know anything about the Miracle. He had been trying to find out about it. He also told Jack that something called [[the Blessing]] was involved. The police soon arrived and Jack was forced to leave. Jack returned to Torchwood's base and began to investigate the Blessing. Gwen contacted him using the [[Eye-5]] contact lenses, and Jack recorded Gwen blowing up the [[module]]s at the [[Cowbridge Overflow Camp]]. He also put Rex's footage of both the [[San Pedro Overflow Camp]] and Vera's death online with Gwen's, starting public outrage at the conditions that the injured and ill were enduring; however, as "Torchwood wasn't designed to fight politics," they had no more success than that. ([[TV]]: {{cs|The Middle Men (TV story)}})

Gwen received a message on the Torchwood contact lenses, telling her they had Rhys, [[Mary Cooper|her mother]], and [[Anwen Williams|Anwen]]. She would have to hand over Jack if she wanted to see her family again. Gwen returned to LA, and asked Jack to come outside. Once outside, Gwen stunned Jack and tied him up in the car. She drove him to where the contact lenses instructed her. Once they arrived at the specified location and a van arrived carrying three people, Rex and Esther revealed that they had followed them. They pointed sniper rifles at the people from the van. Jack was told they wanted to take him to [[Angelo Colasanto]], the only person who knew the true nature of the Miracle. ([[TV]]: {{cs|Immortal Sins (TV story)}})

The person who had arranged to have Gwen's family kidnapped was [[Olivia Colasanto]], Angelo's granddaughter. Olivia took Jack and the rest of the Torchwood team to Angelo's house, where Jack was told Angelo had been able to live to over a hundred years through artificial means, but had aged normally and was in a coma on life support. Angelo had become wealthy thanks to the advice Jack had given him and kept pictures of him from throughout the [[20th century]]. Olivia explained that three families, [[Ablemarch]], [[Costerdane]] and [[Frines]], had made a deal to purchase Jack back in [[1926]] for his immortality. When he escaped, they vowed to find him again, destroying all evidence of their existence to cover their tracks.

Rex soon brought the CIA to Angelo's house, and [[Allen Shapiro]] had Olivia and [[Brian Friedkin]] arrested; Friedkin killed himself and Olivia with a bomb to escape the families' wrath for failing. Jack spoke to Angelo even though he was unconscious, and unplugged Angelo's life support equipment, assuming that he would survive due to the Miracle, and was surprised when Angelo died. After Shapiro had Gwen deported to Wales, Jack discovered a [[null field generator]] under Angelo's bed that cancelled out the [[morphic field]] that had caused the Miracle in the first place. Jack didn't want the CIA to obtain the null field technology, so he persuaded Rex and Esther to help him escape with a vital component of the generator. Unfortunately, Jack was shot soon after he escaped. Esther was forced to go with him, while Rex stayed with the CIA. ([[TV]]: {{cs|End of the Road (TV story)}})

Jack spent the next two months with Esther, ending up in Scotland. Esther collected his blood, which she believed relevant to the Miracle. Eventually, they were contacted by Gwen, who told them Oswald Danes was in her house and wanted to speak to Jack. Jack and Esther went to Wales, where Jack [[retcon]]ned a man who was watching Gwen's house before going in. Oswald explained to Jack that he had stolen [[Jilly Kitzinger]]'s laptop. He knew what she was doing for the families. Jilly was helping them to mistranslate video from other countries to hide the location of the Blessing. Torchwood realised that there were two Blessings, one in [[Shanghai]], and one in [[Buenos Aires]]. Jack went to Shanghai with Gwen and Oswald. Once they arrived there, his gunshot wound began to hurt more. Gwen helped him change his bandage, and Oswald noticed that Jack's blood was moving by itself. Gwen determined that Jack's blood must be moving towards the Blessing. ([[TV]]: {{cs|The Gathering (TV story)}})

=== Back to abnormal ===
With Oswald's help, Jack and Gwen located [[the Blessing]], which was about to be blown up by the Families to bury it forever. They knew that Torchwood had located it. Strapping Oswald to a bomb, the three forced their way into the Blessing. Rex and Esther were captured while trying to infiltrate the Blessing in Buenos Aires. Jack, despite being from the future and having had experiences with the Doctor, had no idea what the Blessing really was. He believed it to have been on Earth since the beginning. The Blessing seemed to show everybody themselves, but Jack didn't appear significantly affected by seeing all the lives he had lived. Jack learned that his blood was used to change the Blessing, which ran Earth's [[morphic field]]. Jack realised the Blessing changed in self-defence and that his mortal blood could change it back. [[The Mother|A family member]] revealed that mortal blood would need to be put into the Blessing from both ends to reverse the Miracle. Jack would have no way to do it. Rex, however, had transfused Jack's blood into his own body.

The two men were prepared to sacrifice themselves to end the Miracle, but Esther was shot by the Families to prevent this, as ending the Miracle would kill Esther. The two decided to end the Miracle anyway, and Gwen shot Jack while Rex removed his bandage. Jack appeared to die of the gunshot wound. Oswald decided to stay behind to blow up a family member, and Gwen and Jilly decided to escape. Jack's immortality returned and he escaped with Gwen as Oswald detonated his bomb. Rex also survived the ordeal, but Esther did not make it.
[[File:Jack and gwen surprised.jpg|left|thumb|Jack and Gwen react to Rex's immortality. ([[TV]]: {{cs|The Blood Line (TV story)}})]]
The friends attended Esther's funeral. There, [[Charlotte Wills]] exposed herself as the CIA mole that kept the Families informed about actions taken against them and killed Rex before being killed herself. Rex resurrected, having somehow gained Jack's immortality. ([[TV]]: {{cs|The Blood Line (TV story)}})

=== Taking a holiday ===
After the events of Miracle Day, Jack decided to take a holiday away from humanity, and find solitude by going to [[Cotter Paluni's World]]. ([[AUDIO]]: {{cs|Red Skies (audio story)}}) After this, Jack then returned to Cardiff to assist [[Andy Davidson]] solve the mystery of Mr Invincible. ([[AUDIO]]: {{cs|Mr Invincible (audio story)}})

By [[2013]], [[Jack Harkness' vortex manipulator|Jack's vortex manipulator]] was held in [[UNIT]]'s [[Black Archive]]. A [[Zygon]] posing as [[Kate Stewart]] told [[Clara Oswald]] it was bequeathed to the UNIT archive by Jack on the occasion of his death, "one of them". ([[TV]]: {{cs|The Day of the Doctor (TV story)}})

Jack was captured by [[Adam Mitchell]] and trapped with many other [[companion]]s of [[the Doctor]] in [[Adam Mitchell's fortress]]. ([[COMIC]]: {{cs|The Choice (comic story)}}) Along with the others, he was released by [[Frobisher]] and assisted the first eleven [[incarnation]]s of the Doctor as they fought through {{Ainley}}'s army of [[Auton]]s. After Adam thwarted the Master's plot to destroy the universe at the cost of his life, all the Doctors and their companions oversaw his memorial before taking their leave. ([[COMIC]]: {{cs|Endgame (POT comic story)}})

=== Return to the fight ===
{{Section stub|Info from {{cs|Station Zero (comic story)}} needs to be added}}
In [[2012]], Jack Harkness returned to [[Earth]] to assist [[Gwen Cooper]], [[Rhys Williams]] and [[Andy Davidson]] to stop an attempt by the [[Mandragora Helix]] to attack [[Earth]]. ([[PROSE]]: {{cs|Exodus Code (novel)}}) Jack then travelled with the crew of the ''[[Ice Maiden (ship)|Ice Maiden]]'', an ice-rigging ship augmented with alien technology, to explore Earth and other planets. ([[COMIC]]: {{cs|World Without End (comic story)}})

Jack realised that [[the Committee]] was behind the Three Families and, hoping to find out how [[the Evolved]] had kept their worlds safe from the Committee, travelled to [[Peritus IV]]. He begged the Evolved to help him save Earth and agreed to a controlled experiment of their technology upon humans. When he learnt of what that entailed, they held him captive and tried to kill him.

Due to his immortality, the Evolved instead transferred him into the body of [[Griffith (Forgotten Lives)|Mr Griffith]] at [[Bryn Offa Residential Care]]. He had [[Elunedd]] call Gwen and later offered the Evolved his mind in return for Rhys, Anwen and the other people whose minds they had swapped being restored. ([[AUDIO]]: {{cs|Forgotten Lives (audio story)}})

Travelling from the third planet in the [[Otega system]], back to Earth, Jack and the crew of the ''Ice Maiden'' were attacked by ninjas on jet-skis who came from a flying saucer. ([[COMIC]]: {{cs|World Without End (comic story)}})

=== Sorvix occupation ===
==== Leading the new Torchwood ====
After being "dumped" by the crew of the ''Ice Maiden'', ([[AUDIO]]: {{cs|Aliens & Sex & Chips & Gravy (audio story)}}) Jack resumed his work with Gwen at Torchwood. They were joined by [[St John Colchester]] and operated from a partially-restored Hub. ([[AUDIO]]: {{cs|Changes Everything (audio story)}}) He was unaware of Gwen's possession by [[Ng]]. ([[AUDIO]]: {{cs|Orr (audio story)}}, etc.) The three became aware of the presence of [[Sorvix|an alien race]] that had taken over the city and Jack set his sights on [[Tyler Steele]] to join them due to his skills with [[computer]]s and investigation.

Jack vetted Tyler whilst investigating [[3Sol]] but refused to let him join after he encouraged [[Vorsun]] to kill her human [[hostage]]s, although he did tell him to continue looking into the aliens. ([[AUDIO]]: {{cs|Changes Everything (audio story)}}) They continued a sexual relationship. The two of them met [[Orr]], whom Jack drove out of Cardiff to protect the city from the explosive [[control necklace]], and Jack began to feel distanced from "Gwen" when she did not invite him to [[Mary Cooper|her mother]]'s [[Mary Cooper's funeral|funeral]]. ([[AUDIO]]: {{cs|Orr (audio story)}}) He posed as a [[bartender|barman]] at the [[Cardiff Bay Intelligent Hotel and Spa]] to gather information and later killed himself to shut down the CPU. At the Hub, he invited Orr to join them. ([[AUDIO]]: {{cs|Superiority Complex (audio story)}})

Jack was infected by [[parasite (Love Rat)|a parasite]] after being [[rape]]d by [[Duncan B.|Duncan]]. He went on to infect Tyler and Ng and, after the three were given [[curative worm]]s by [[Ro-Jedda]], Tyler called off their relationship and told Jack to do something about [[Red Doors]]. ([[AUDIO]]: {{cs|Love Rat (audio story)}}) He and Orr went to help [[Andy Davidson]] with a hostage situation whilst Mr Colchester went to [[Ritz Tower]] to save [[Colin Colchester-Price|Colin]] ([[AUDIO]]: {{cs|A Kill to a View (audio story)}}) and went to [[Neath]] to get spare parts for the [[Rift Manipulator]] when [[Deliverables]] began taking control. ([[AUDIO]]: {{cs|Zero Hour (audio story)}})

To save Andy and prevent 3Sol from gaining complete control of policing, Jack allied himself with [[Xander Vaughn]] of Red Doors, promising to supply them with [[quantum tech]] in return for their help in locating [[Helen White]] and thwarting Ro-Jedda's plans. He recruited a number of students to the Red Doors cause and supplied them with [[flash grenade]]s and the like for the [[protest]]. In the end, he reached a compromise with Ro-Jedda. ([[AUDIO]]: {{cs|The Empty Hand (audio story)}}) [[Yvonne Hartman (Pete's World)|Yvonne Hartman]] arrived at the Hub afterwards and exposed him, also framing him for helping Red Doors place [[glitterbomb]]s around the city. Torchwood turned against him and Yvonne took his place, telling Jack to join Red Doors and put them to a better use. ([[AUDIO]]: {{cs|Poker Face (audio story)}})

==== Leading Red Doors ====
From the ruins of the intelligence of the [[Cardiff Bay Intelligent Hotel and Spa]], Jack engineered [[the Meme]] with the intention of using it to encourage rebellion against the Sorvix. However, Red Doors altered it into instead encouraging [[violence]] and [[revenge]]. Mr Colchester asked Jack to meet with him and admonished him for his role. ([[AUDIO]]: {{cs|Tagged (audio story)}})

Jack tempered Red Doors and directed them solely against the Sorvix and empty buildings. However, he was unable to prevent them from [[bomb]]ing [[Cardiff Airport]] and died in the explosion. With Orr, he decided to bring an end to Red Doors and met with [[Bernstein (Herald of the Dawn)|Inspector Bernstein]] to take them down, although they found that Yvonne and 3Sol already got to them. He returned to the Hub after warning [[Cardiff City Hall]] of the oncoming bomb attack and allowed the Rift to open, splitting Gwen from Ng. He said goodbye to his friend as she left with [[Rhys Williams|Rhys]]. There was an explosion at the Hub ([[AUDIO]]: {{cs|Herald of the Dawn (audio story)}}) which made Jack mortal again. ([[AUDIO]]: {{cs|See No Evil (audio story)}})

=== God and the Committee ===
Due to what she did to Gwen, Jack avoided Ng and did not talk to her. ([[AUDIO]]: {{cs|Future Pain (audio story)}}, {{cs|Night Watch (audio story)}}) He hunted the [[plasmic psychovore]] under the misconception that it was [[God (Future Pain)|God]] and was almost late to [[St John Colchester's funeral|Mr Colchester's funeral]] because of it. He was surprised and confused when Orr transformed into him in [[Colin Colchester-Price|Colin]]'s presence and was convinced by them into rejoining Torchwood as they had reservations about Yvonne. ([[AUDIO]]: {{cs|Future Pain (audio story)}})

Jack convinced to [[Jo Jones]] to come with him to [[Llanfairfach]] to investigate [[Proper Grub]]. In the mines he was bitten by one of the [[Maggot]]s and started to glow green. He discovered with Jo that [[BOSS]] was behind it and they the supposed [[vegan]] food was actually made from the maggots. He struck a deal with BOSS for the giant maggots and flies to stay in the mines. ([[AUDIO]]: {{cs|The Green Life (audio story)}})

[[Brent Hayden]] believed that Jack and Orr watched a [[speech]] that he made concerning [[racism]] and [[conspiracy|conspiracies]] and that they planned to destroy him. Brent also imagined that he was a [[homophobia|homophobic]] [[Yank]] who used language and phrases from old [[film]]s. ([[AUDIO]]: {{cs|The Man Who Destroyed Torchwood (audio story)}})

Jack avoided Ng and went to help Colin when [[predator (See No Evil)|a predator]] shrouded Cardiff in [[darkness]]. His [[night-vision goggles]] were broken in [[St Martin's]] but he let Colin continue to believe that he was wearing them despite the fact that Colin himself was the one leading them to [[Ritz Tower]]. In [[Flat 151]], Jack told Colin that he thought that he had become mortal again. Colin kissed Jack, whereupon Mr Colchester appeared and asked Jack what he was doing. ([[AUDIO]]: {{cs|See No Evil (audio story)}})

Believing Mr Colchester to be a ghost, Jack returned to the Hub unaware that the [[light (Night Watch)|blue light]] had latched onto him and was giving [[waking nightmare]]s to those disconnected from him, namely Yvonne, Tyler and Mr Colchester. Orr later absorbed the light from him and he decided to make an effort with Ng. He protested when Yvonne said that she was going to use the [[pharadyne projector]] to bring back [[Ianto Jones|Ianto]] and witnessed when, instead, [[Norton Folgate]] appeared. ([[AUDIO]]: {{cs|Night Watch (audio story)}})

Jack was on a rooftop when Mr Colchester approached him, telling him to keep away from his husband and asking about resurrection. Jack believed that he had become immortal again thanks to the [[Night Sun]]. ([[AUDIO]]: {{cs|Flight 405 (audio story)}}) He convinced Yvonne to let Tyler live in a repurposed cell in the Hub and told him to talk to him should he ever need to. ([[AUDIO]]: {{cs|Hostile Environment (audio story)}})

After having sex with seven [[Penashi]], Jack found himself in Mr Colchester's body and pretended to be him so as not to ruin Colin's [[birthday]]. He took him on a tour of rooftops and to watch the [[duck]]s before receiving a [[text]] telling him of a reservation at [[Antonio's]]. There, he convinced Mr Colchester that it was in Colin's best interests that he continue pretending to be him, later taking him through Mr Colchester's [[Rift corridor]]s. When their bodies switched back, Mr Colchester was grateful. ([[AUDIO]]: {{cs|Another Man's Shoes (audio story)}})

Jack, Mr Colchester, Ng and Norton travelled in [[Torchwood submersible|a submersible]] to the [[Sorvix power station]] to stop it from exploding and destroying western [[Europe]]. He and Norton went to shut the station down, but Norton trapped him in a concentration filter and had him absorb the energy, also admitting that he was working for [[the Committee]]. Jack was saved by Ng and he later saved Mr Colchester from [[drowning]]. The three were in the submersible when the [[tsunami]] hit Cardiff. ([[AUDIO]]: {{cs|Eye of the Storm (audio story)}})

=== After the tsunami ===
Jack planned for Torchwood to go back underground and had Andy start working for him as a [[spy]], becoming [[director]] of the [[Disaster Recovery Committee]] and ostensibly working for the Committee. ([[AUDIO]]: {{cs|Thoughts and Prayers (audio story)}})

Two months after the tsunami hit, Jack planned to expose Yvonne for her role. He attended [[inquiry (A Mother's Son)|the inquiry]] into the response of the [[emergency services]] and told [[Bethan Foster]] that there was clearly a cover-up, as well as saying that Yvonne was powerful and dangerous. This eventually resulted in Bethan realising that the drinking [[water]] contained [[retcon]], replacing it and exposing Yvonne. ([[AUDIO]]: {{cs|A Mother's Son (audio story)}})

Jack approached Yvonne outside of the [[Disaster Recovery Committee]] building and fled from a security guard with her to a "crappy car" that he said would let them sit unnoticed. They discussed the situation and, whilst Yvonne went to [[God (Future Pain)|God]], Jack went to the [[Ritz Tower camp]]. He was shot and killed by [[security guard (Day Zero)|a security guard]] when he tried to stop him from shooting [[boy (Day Zero)|a boy]]. Andy had him taken away when he did not revive. ([[AUDIO]]: {{cs|Day Zero (audio story)}})

Andy took Jack's body to a jail cell where he was joined by [[God (Future Pain)|God]]. The two of them left the cell and went to the Hub, leaving Yvonne and Orr in there with the [[Lens]] to destroy the Committee and [[Erebus]]. Jack saved the two of them on the [[invisible lift]] after the Hub began falling apart and went on the run with Ng, Mr Colchester, Orr and Tyler when Andy informed them that they were fugitives. ([[AUDIO]]: {{cs|Thoughts and Prayers (audio story)}}) The split up team subsequently lost contact with Jack. ([[AUDIO]]: {{cs|Aliens Next Door (audio story)}}) Ng later asked Gwen if she'd heard from him, which she hadn't. ([[AUDIO]]: {{cs|Misty Eyes (audio story)}}) His disappearance was known to [[Kristin (Heistland)|Kristin]], leader of Torchwood's Icelandic counterpart. ([[AUDIO]]: {{cs|Heistland (audio story)}})

=== Ally of the Thirteenth Doctor ===
[[File:Jack's back (FOTJ).jpg|thumb|Jack greets [[Graham O'Brien]], mistaking him for the Doctor. ([[TV]]: {{cs|Fugitive of the Judoon (TV story)}})]]
In [[2020]], Jack travelled in a stolen spaceship to warn the Doctor about the [[Ashad|Lone Cyberman]] and [[Cyberium|what he was searching for]]. He caught up with [[Team TARDIS]] in [[Gloucester]], but was only able to make contact with [[Graham O'Brien|Graham]], [[Ryan Sinclair|Ryan]], and [[Yasmin Khan|Yaz]] due to interference by the [[Judoon]] who were hunting [[The Doctor (Fugitive of the Judoon)|an unknown incarnation]] of the Doctor. With the ship's previous owners and defense [[nanogene]]s attacking, Jack explained that [[The Alliance (Fugitive of the Judoon)|the Alliance]] had sent something back through time that the Lone Cyberman was after and that the [[Thirteenth Doctor]] must not give the Cyberman what it wanted or risk the [[Fall of the Cyber-Empire|fallen]] [[Cyber-Empire]] rising again. Before teleporting away, Jack said that it would be some time before the Doctor saw him again, but he would be there if she needed him. The Doctor was pleased to hear from her old friend again, ([[TV]]: {{cs|Fugitive of the Judoon (TV story)}}) but was ultimately forced to ignore Jack's warning when the time came due to the circumstances surrounding the event. ([[TV]]: {{cs|The Haunting of Villa Diodati (TV story)}})

Jack later learned that the Doctor had been locked in [[maximum security facility|prison]] and purposefully got himself arrested for a number of unspecified crimes in order to break her out. After nineteen years, Jack managed to reach the adjoining cell to the Doctor's and drew her attention by knocking four times on the wall. The next day, Jack revealed himself and used a device the surrounded them in a bubble of frozen time to race himself and the Doctor to a hidden compartment in another cell containing [[Jack Harkness' vortex manipulator|his repaired vortex manipulator]]. Dodging questions about how he had smuggled it in, Jack teleported them away as the alarms went off.

Returning the Doctor to her TARDIS, the two reminisced and Jack was dismayed to learn that the Doctor had given the Lone Cyberman the Cyberium although she reassured Jack that she eventually fixed it "[[Restoration of the Cyber-Empire|sort of]]." Jack was surprised to learn that she had been locked up for running from the Judoon twice at once and only 7,000 other offences. Upon returning to Earth, Jack happily greeted Team TARDIS, only to learn that it had been ten months for them. Yaz, Graham and Ryan revealed that they were dealing with a Dalek threat and the group tried to figure it out with Jack explaining his immortality and how the Daleks had once killed him a long time before.

While the others went to interrogate [[Jack Robertson]] for answers, Jack and Yaz went to investigate the corrupted Dalek DNA trace that the TARDIS had detected. Jack reminisced on his 51st century origins and sympathized with Yaz's fear of the Doctor not coming back based on his own experiences. Jack warned Yaz that being the Doctor's [[companion]], you had no choice in when it stopped, whether you left the Doctor or they left you. However, despite how hard it is to experience traveling with the Doctor and then losing it, Jack told Yaz that it was worth it and to enjoy it while she had it "because the joy is worth the pain."

Opening the door to the facility with his [[sonic blaster]], Jack and Yaz discovered to their horror that the facility was a clone farm growing thousands of cloned Daleks. Jack began planting explosives to blow the facility up as Yaz gathered samples of the Dalek mutants food in the hopes of finding a way to stop them. The two came under attack by Dalek mutants, but Jack managed to kill them with his sonic blaster. Shortly thereafter, the Doctor, Ryan, Graham and Robertson arrived in the TARDIS with Jack expressing pleasure at hearing the TARDIS again. The group was confronted by [[Reconnaissance Dalek|the Dalek]] responsible for the creation of the clone farm possessing [[Leo Rugazzi]]. The Dalek explained how it connected itself into Robertson's systems and used them create the clone farm and its new race of Daleks, disgusting Jack to learn that they were being fed liquidized humans. The Dalek revealed that it intended to use Earth as a base to begin a conquest of the universe and utilized [[ultraviolet light]] to teleport the Daleks into their [[Defence Drone]] shells. Robertson revealed that thousands of drones had been built before the Dalek killed Leo and disappeared.

Returning to the TARDIS, the Doctor announced to the others that their only chance was the nuclear option that might backfire upon them. Jack immediately realized what the Doctor meant and warned her that it was a planet-threatening risk. However, Jack didn't have any better ideas to stop the threat. The Doctor explained that the Daleks were built from the original [[Reconnaissance Dalek]] and she would give them what they wanted. The Doctor began to send a message through the [[Time Vortex]] and Jack told Yaz that she was doing something that you never want to do. The message was received by [[Dalek Death Squad spacecraft|a]] [[Dalek saucer]] containing [[Death Squad Dalek]]s with the Doctor revealing that her plan was to bring in more Daleks to deal with the Defence Drones, although they must not know that she was there. However, they will have to deal with the new Daleks once the Defence Drones are dealt with.

The Doctor's plan succeeded and thousands of Death Squad Daleks [[2021 Dalek civil war|exterminated the Defence Drones]], but Robertson betrayed the group. In order to stop the Death Squad Daleks, the Doctor asked Jack to blow up their ship which he was only too happy to do and Ryan and Graham volunteered to help. Jack armed the two men with some of his bombs and the Doctor and Yaz ordered them not to detonate until they were sure that all of the Defence Drones were destroyed and until the men were clear of the ship. Jack teleported the three to the saucer using his vortex manipulator and they began to spread out and plant bombs. However, the ship's internal sensors detect non-Dalek lifeforms onboard and Jack witnesses Robertson betraying them and warning the Daleks about the Doctor. After witnessing the extermination of the last of Robertson's Daleks, Jack warned the Doctor that Robertson had sold her out to the Daleks. Coming up with a plan to deal with the remainder of the Daleks, the Doctor ordered Jack to stand by for Yaz's signal to teleport out and destroy the ship. Jack, Ryan and Graham rescued Robertson, but became cornered by Daleks. Yaz gave the signal and after introducing himself, Jack teleported them out as the Daleks fired. Ryan detonated the bombs as they left, destroying the Dalek saucer. Returning to the TARDIS, Jack was elated to learn that the plan had worked and that all of the Daleks were destroyed, embracing Yaz as the Doctor confronted Robertson over his betrayal.

After the defeat of the Daleks, Jack departed from the TARDIS again, leaving a message that he was staying on Earth to catch up with [[Gwen Cooper]] but promising to call the Doctor. ([[TV]]: {{cs|Revolution of the Daleks (TV story)}})

=== Far future ===
{{Section stub|Info from {{cs|Mighty and Despair (audio story)}} needs to be added}}
Now owning the "latest model" of [[vortex manipulator]], Jack was contacted by the Doctor's automated helpline to rescue [[River Song]] after she'd jumped out of [[Stormcage]] into space. He retrieved her in an air bubble and gave her a lift to her home in [[1939]] [[New York City]]. ([[PROSE]]: {{cs|The Ruby's Curse (novel)}})

Jack and Torchwood helped the [[Human Empire]] to combat [[the Enemy (The Torchwood Archive)|the Enemy]]. He befriended [[Jeremiah Bash Henderson]] and asked him to visit the [[Torchwood Archive]], which had travelled beyond the Empire's space. This may all have been a lie, as Jeremiah confessed to having faked a “sob story” to infiltrate the Archive. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

=== Potential fate ===
Before the Doctor had reason to ponder that Jack was the [[Face of Boe]], ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) whose [[death]] he had previously witnessed; ([[TV]]: {{cs|Gridlock (TV story)}}) if Jack was indeed the Face of Boe, he once unknowingly visited his own [[funeral]]. ([[AUDIO]]: {{cs|R&J (audio story)}})

Before he had reason to speculate Jack was the Face of Boe, ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) the [[Tenth Doctor]] speculated another fate; that Jack, being immortal, could well still be alive by the [[end of the universe]] in the [[year]] [[100,000,000,000,000]]. ([[TV]]: {{cs|Utopia (TV story)}})

=== Legacy ===
Shortly before his regeneration began, the [[Twelfth Doctor]] dreamt of Jack saying his name. ([[TV]]: {{cs|The Doctor Falls (TV story)}})

As a member of Torchwood, Jack's likeness was among those assumed by the [[intuitive hard-light simulation]]s of the [[Torchwood Archive]]. ([[AUDIO]]: {{cs|The Torchwood Archive (audio story)}})

== Parallel worlds ==
=== Donna's World ===
In a [[Donna's World|parallel world]] where [[Donna Noble]] never saved the [[Tenth Doctor]], Jack lost fellow Torchwood members [[Gwen Cooper]] and [[Ianto Jones]], who sacrificed their lives to save the Earth from the [[Sontaran]]s' [[Sontaran invasion of Earth|plan involving ATMOS]], and was transported to [[Sontar]], the Sontaran homeworld. ([[TV]]: {{cs|Turn Left (TV story)}})

== Alternate timelines ==
John Hart once created an [[Alternate timeline (The Death of Captain Jack)|alternate timeline]] by marrying Queen [[Victoria]]. Jack came to stop him and John shot him, discovering his inability to die. He used Torchwood technology to siphon energy off him, and used it to extend his life. Jack took back what was stolen from him and told John that when he died, the world would return to normal and John would be trapped. ([[AUDIO]]: {{cs|The Death of Captain Jack (audio story)}})

In an [[Alternate timeline (Supremacy of the Cybermen)|alternate timeline]] created when [[Rassilon]] allied with the [[Cyberiad]], the [[Cyberman|Cybermen]] used [[Time Lord]] resources to conquer all of history. The Ninth Doctor, Jack and Rose fought on the [[Cyber-Earth]] in [[2006]], rescuing [[Jackie Tyler]]. When they tried to reclaim the TARDIS, the ship exploded. As the group evacuated, Rose fell victim to the Cybermen's [[techno-virus]] and was upgraded into a [[Cyber-Warrior]], shooting Jack dead. This sequence of events was later undone by the [[Twelfth Doctor]] with the aid of a remorseful Rassilon. ([[COMIC]]: {{cs|Supremacy of the Cybermen (comic story)}})

== Personality ==
[[File:Jack flirts with Chantho.jpg|thumb|Jack "says hello" to [[Chantho]]. ([[TV]]: {{cs|Utopia (TV story)}})]]
Jack Harkness' personality was wilfully enigmatic. He enjoyed his persona of "mysterious time traveller", much of which remained constant in his experiences with Torchwood and the Doctor. Before being cursed with immortality, he was a flippant former con man who loved adventuring with the Doctor and seducing beings throughout the universe. Jack automatically flirted with most people he met, not caring about their gender or if they were human, alien or even robots. The Doctor often told him to stop and Jack would often reply, "I'm just saying hello". But as the Doctor pointed out, "For you, that's flirting". ([[TV]]: {{cs|Bad Wolf (TV story)}}, {{cs|Utopia (TV story)}}, {{cs|Journey's End (TV story)}}, {{cs|The End of Time (TV story)}})

Besides being a flirt, Jack was a drinker. He once remarked that on one occasion when he was sentenced to death, he got drunk and ended up in bed with both his executioners. ([[TV]]: {{cs|The Doctor Dances (TV story)}}) He told Rose that he preferred to discuss business while he was drinking. ([[TV]]: {{cs|The Empty Child (TV story)}}) He smoked but gave up in the [[1980s]]. ([[AUDIO]]: {{cs|A Mother's Son (audio story)}}) Jack claimed to the [[Ninth Doctor]] that before he met him he had been a coward and said that he might have been better off that way. ([[TV]]: {{cs|The Parting of the Ways (TV story)}})

Despite the fact that he was incapable of dying even if he wanted to, Jack retained a sense of humour, frequently telling jokes and being lively and cheerful. However, underneath his cheerful demeanour, Jack was unsure if he wanted to die or not. ([[TV]]: {{cs|Utopia (TV story)}}) Living forever (or at least as near to forever as a human could live) brought him to an existential viewpoint. While he joked about grey hairs and remained silent about mortality, Jack saw death as the ultimate end of being; there was no afterlife and no one waiting for him from his past lives. Jack expressed annoyance at people in the 21st century being unable to figure out that aliens exist, believing the [[Sycorax]] invasion on the Christmas of 2005 and the [[Battle of Canary Wharf]] were more than enough proof that they did. ([[TV]]: {{cs|The Christmas Invasion (TV story)}}, {{cs|Doomsday (TV story)}}, {{cs|Everything Changes (TV story)}}) While escaping a Dalek saucer, Jack gleefully told the surrounding Daleks that "I'm Captain Jack Harkness and I'm immortal." ([[TV]]: {{cs|Revolution of the Daleks (TV story)}})

Although friendly and flirtatious, Jack could also be ruthless at times and did not hesitate to kill anyone or anything that he felt was a threat. He was also equally unwilling to do anything that could endanger the [[Torchwood]] facility. This sometimes got him into trouble with his allies who disapproved of his lack of compassion. An example of this was when he tried to force [[Ianto Jones]] to execute his girlfriend [[Lisa Hallett]], who had been turned into a [[Cyberman]], instead of letting someone else do it. He reasoned that the entire thing was Ianto's responsibility and even threatened to kill them both if he didn't do it, causing Ianto to say "You like to think you're a hero, but you're the biggest monster of all". ([[TV]]: {{cs|Cyberwoman (TV story)}}) Another example of his ruthlessness was when he refused to open the Rift despite it being their best chance to change everything back to normal, even insulting the rest of the team when they attempted it. This caused [[Owen Harper]] to shoot him because he felt that Jack didn't care about what they had lost. ([[TV]]: {{cs|End of Days (TV story)}}) Because of these incidents, the entire team was surprised by Jack's desire to save the [[Cash Cow]], with [[Gwen Cooper]] going so far as to imply she thought he didn't have a heart. ([[TV]]: {{cs|Meat (TV story)}}) Indeed, although he could be aggressive, Jack still cared deeply about his allies and was devastated when any of them were killed. ([[TV]]: {{cs|Exit Wounds (TV story)}}, {{cs|Children of Earth: Day Five (TV story)}})

Always a vocal, unreliable narrator of his own adventures, Jack was as much of a mystery to the people he met as the countless lives he claimed to have led. Jack continued to protect himself with an air of mystery. No one he encountered knew his real name or many details about his career or life. He often told anecdotes about his sex life, but no one knew how many were real, however since he was a successful flirt, it is likely a lot of his tales were true. He rarely told his teammates anything about himself or his past unless the situation demanded it; Gwen even once lamented the fact that they knew almost nothing about him and that he just came and went whenever he felt like it. This was because Jack believed that his past didn't matter and that who he was now was important. He was shown to greatly dislike being reminded of his past, such as his desperation to remove [[Captain]] [[John Hart (Kiss Kiss, Bang Bang)|John Hart]] from his life as he was a reminder of his past. In contrast to this mysterious nature, Jack could also be brutally honest at times, such as when he bluntly told [[Beth Halloran]] that she was a ruthless killing machine and that there was nothing they could do to change that. ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}, {{cs|Sleeper (TV story)}})

Despite being [[immortal]], and so coming back after being [[kill]]ed numerous times, Jack continued to have a [[fear]] of [[death]], which he acknowledged during the [[Gallipoli campaign]] of [[World War I]]. He remained ever uncertain whether his next death would be his last. ([[AUDIO]]: {{cs|What Have I Done? (audio story)}})

Though he professed "responsibility" as his motto after [[the Year That Never Was]], the utter devastation Jack experienced in the space of five days over the course of the 456 incident and the deaths of his grandson and Ianto Jones left him wrecked with guilt and grief, unable to remain on Earth. When he returned to Earth, Jack seemed to be a shadow of his old self because he had lost so many people he cared about, although he had recovered enough to stay on Earth in order to defend it. ([[TV]]: {{cs|Children of Earth: Day Five (TV story)}}, {{cs|Miracle Day (TV story)}})

Jack was haunted by the loss of his younger brother Gray and spent many decades searching for him. He blamed himself for Gray's disappearance because he'd let go of his hand when they were fleeing from aliens during their childhood, describing it as the worst day of his life. Jack loved his brother deeply and, even after Gray turned against him, Jack told him that he forgave him. However, Gray refused to give him absolution and Jack had no choice but to chloroform him and seal him in the cryo-chambers. [[John Hart (Kiss Kiss, Bang Bang)|John Hart]] insisted that killing him was the only option, believing that Gray would never recover from the trauma, but Jack refused, believing that there had been enough death. ([[TV]]: {{cs|Adam (TV story)}}, {{cs|Exit Wounds (TV story)}})

Jack possessed a deep hatred of the [[Dalek]]s due to their being responsible for his first death and was only too gleeful at the chance of destroying them. ([[TV]]: {{cs|Revolution of the Daleks (TV story)}})

After becoming a [[companion]] of the [[Ninth Doctor]], Jack retained a great loyalty to the Doctor as a whole, aiding the Doctor's various incarnations as much as he could. After not having seen the Doctor for a very long time, Jack attempted to warn the Doctor, now in their [[Thirteenth Doctor|thirteenth incarnation]], about the [[Ashad|Lone Cyberman]] and the [[Cyberium]] and told [[Team TARDIS]] that if the Doctor ever needed him, he would be there for her. ([[TV]]: {{cs|Fugitive of the Judoon (TV story)}}) After learning that the Doctor had been imprisoned, Jack purposefully allowed himself to be arrested and imprisoned for 19 years just to break her out and enjoyed aiding the Doctor and her companions in defeating [[2021 Dalek civil war|the renewed Dalek threat]] before going his own way again. ([[TV]]: {{cs|Revolution of the Daleks (TV story)}})

In a private conversation with [[Yasmin Khan]], Jack revealed his understanding of the pain of getting left behind by the Doctor and not knowing if they would ever return or were still alive. Due to his long history with the Doctor, Jack knew better than anyone that companions had no choice when their time ended, whether the companion chose to leave or got left behind in the end. However, Jack encouraged Yaz to enjoy her time travelling with the Doctor, as he knew that the joy was worth the pain that would inevitably come. ([[TV]]: {{cs|Revolution of the Daleks (TV story)}})

== Other information ==
=== Skills and abilities ===
==== Pheromones ====
Like other men in the [[51st century]], Jack possessed evolved human pheromones which made him naturally nice-smelling and attractive to others. Ianto thought Jack was wearing aftershave. ([[TV]]: {{cs|Fragments (TV story)}})

==== Immortality ====
After he was first killed when shot by a Dalek, he was resurrected by Rose Tyler as the [[Bad Wolf (entity)|Bad Wolf]]. While using the power of the Time Vortex to restore Jack, Rose couldn't totally control the power she wielded, and she brought him back forever by accident. As such, Jack became a singularity in a fixed point of time, an immortal being that the Doctor had trouble even looking at, and even the TARDIS tried to get rid of him. While undoing Jack's functional immortality was beyond even the Doctor's ability, ([[TV]]: {{cs|Utopia (TV story)}}) Jack still aged, albeit very slowly, having grown a few grey hairs in two centuries' time. ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) When Jack reunited with the [[Thirteenth Doctor]], he had visibly aged, his wrinkle lines becoming more prominent. ([[TV]]: {{cs|Revolution of the Daleks (TV story)}}) In the [[far future]], at a time where the [[Vampire]]s thought the [[Time Lord]]s to be myths, Jack's hair had turned completely grey. ([[AUDIO]]: {{cs|Mighty and Despair (audio story)}})

Since his first resurrection, whenever he did die, he automatically came back to life almost instantly, each time awaking with a very deep gasp of breath as his respiratory system resumed its functions, ([[TV]]: {{cs|The Parting of the Ways (TV story)}}, {{cs|Everything Changes (TV story)}} et. al) though he once reanimated without the gasp. ([[TV]]: {{cs|Journey's End (TV story)}}) However, on occasion his resurrection was delayed if experienced enough trauma. ([[TV]]: {{cs|End of Days (TV story)}}, {{cs|Children of Earth: Day One (TV story)}}) While not understanding the mechanics of his condition, his just-deceased body is apparently held in stasis while time ran backwards over it, repairing wounds and mending the damage. ([[PROSE]]: {{cs|Bay of the Dead (novel)}}) Jack could sense what was done to his body during his brief periods of death, such as when [[Martha Jones]] unsuccessfully attempted to resuscitate him using the [[kiss]] of life. ([[TV]]: {{cs|Utopia (TV story)}}) Jack viewed this power as a curse as much as a blessing, ([[TV]]: {{cs|Everything Changes (TV story)}}) Jack describes the process of resurrection as being "hauled over broken glass." ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}})

Jack could survive heat and radiation which would have burned or vaporised regular humans. ([[TV]]: {{cs|Utopia (TV story)}}) He also didn't need an immune system, as his body never needed to build up any resistance, although this meant he would easily fall ill without his immortality. ([[TV]]: {{cs|Rendition (TV story)}}) Jack's immortality granted him regenerative powers far beyond those of the [[Time Lord]]s, allowing him to automatically restore himself to perfect condition without changing his appearance or personality as Time Lords were forced to do when they regenerated. Jack could fully regenerate an infinite number of times as opposed to a Time Lord's fixed set of twelve regenerations. However severe enough trauma could delay his resurrection, such as suffering the pallor of a corpse before returning to full health. He could even re-grow his whole body; when he was blown up after having a bomb implanted in his stomach, he fully regenerated from just an arm, a shoulder, and part of his head in a bit over twelve hours. His regeneration process began with growing bones, followed by his internal organs, and lastly his flesh and skin. He also retained all his memories and knowledge as well.

The process of resurrection could often be very painful, especially in this instance. He regained consciousness before his healing was complete, with his eyes and his flesh yet to regrow, but the ability to feel pain intact, causing Jack to scream for hours on end and hold extreme resentment to those who planted the bomb inside him. ([[TV]]: {{cs|Children of Earth: Day Two (TV story)}}) Pain appeared to be dependent on the amount of damage to the body, with more pain in cases where foreign objects remained within the wound. ([[TV]]: {{cs|Fragments (TV story)}}, {{cs|Children of Earth: Day Two (TV story)}}) Jack's body would heal around objects lodged inside his body, such as [[bullet]]s or [[shrapnel]], but would otherwise remain completely healthy. ([[WC]]: {{cs|Web of Lies (webcast)}}) Asphyxiation in an airless environment would make him die and instantly revive in cycle endlessly if he was never unearthed. ([[TV]]: {{cs|Exit Wounds (TV story)}}) It is theorized that there is a limit to how much he can regenerate from as after being asked by Ianto what would happen if his body were totally destroyed, Jack merely said "Maybe we ought to try it some time". ([[PROSE]]: {{cs|Bay of the Dead (novel)}}) Notably, although Jack quickly recovered from fatal injuries, minor injuries sustained like a cut lip or a black eye will remain and heal at the rate of a normal human. ([[TV]]: {{cs|Cyberwoman (TV story)}}, {{cs|Fragments (TV story)}})

An interesting side effect, used only once on record, was the ability to heal another being, allowing that person to recover very quickly, although this may have only been possible as the subject was possessed by a gaseous entity that drew life energy from others to sustain itself. ([[TV]]: {{cs|Day One (TV story)}}) [[Toshiko Sato|Tosh]] could not use [[Mary (Greeks Bearing Gifts)|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. ([[TV]]: {{cs|Greeks Bearing Gifts (TV story)}})

Jack had no other superhuman abilities as such, but was in excellent physical condition and an expert in various firearms. ([[TV]]: {{cs|Ghost Machine (TV story)}}, {{cs|The New World (TV story)}}, {{cs|Last of the Time Lords (TV story)}}) He was physically strong enough to rip the bolts of chains he had been bound with by the Master out of the wall, which ultimately resulted in the use of special clamps on his restraints. ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) He also demonstrated extremely fast reflexes, such as when he noticed and fired on a Dalek seconds after teleporting from Cardiff to London. ([[TV]]: {{cs|The Stolen Earth (TV story)}}) He was also a skilled fighter, capable of taking out several trained soldiers and CIA bodyguards with little assistance, ([[TV]]: {{cs|Bad Wolf (TV story)}}, {{cs|Rendition (TV story)}}) and successfully tackled and pinned Angelo Colasanto. ([[TV]]: {{cs|Immortal Sins (TV story)}}) He even went toe to toe with fellow time agent [[John Hart (Kiss Kiss, Bang Bang)|John Hart]]. ({{cs|Kiss Kiss, Bang Bang (TV story)}}) He was overpowered, however, by Angelo and Gwen Cooper, the latter of which disabled him with a single punch. ([[TV]]: {{cs|Immortal Sins (TV story)}}, {{cs|End of Days (TV story)}}) [[Rhys Williams]] also punched Jack to the ground. ([[TV]]: {{cs|Something Borrowed (TV story)}})

=== Future as the Face of Boe ===
Jack had mentioned that in his childhood home, the [[Boeshane Peninsula]], he was referred to as the "Face of Boe," a poster-boy name resulting from being the first one ever to sign up to the Time Agency. This led the Doctor and Martha to speculate that Jack may in fact become the [[Face of Boe]] himself. ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) Jack had previously mentioned that he did know of the Face of Boe, a being that existed for billions of years. ([[PROSE]]: {{cs|The Stealers of Dreams (novel)}}) Remaining unsure of his continued ageing process due to seeing grey hairs over hundreds of years, Jack inquired of the [[Tenth Doctor]] about his facial appearance if he were to live for a million years and was told he was an "impossible thing," knowing something he had already been told before with no concise answer as to his fate. ([[TV]]: {{cs|Last of the Time Lords (TV story)}})

=== Multiple Jacks ===
Due to Jack's immortality and time travel, there were occasions in which several Jacks existed on Earth at the same time. At the time of Jack's first encounter with the [[Ninth Doctor]] in World War II, there were three versions on Earth: the young mortal Jack who subsequently joined the Ninth Doctor and Rose; ([[TV]]: {{cs|The Empty Child (TV story)}}/{{cs|The Doctor Dances (TV story)}}) the immortal Jack working for Torchwood (location at this point in time unknown); ([[TV]]: {{cs|Utopia (TV story)}}, [[TV]]: {{cs|Fragments (TV story)}}) and a still older Jack being kept in cryogenic sleep at the Torchwood Three Hub in Cardiff. ([[TV]]: {{cs|Exit Wounds (TV story)}}) Later, when the Doctor, Rose, and Jack arrived in Cardiff prior to the [[Blaidd Drwg]] power station incident, they were only feet away from the Torchwood Three Hub where the older Jack was based and the cryogenically frozen Jack awaited resurrection. ([[TV]]: {{cs|Boom Town (TV story)}}, [[TV]]: {{cs|Exit Wounds (TV story)}}) 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 Jacks (the 21st century Jack, the 1940s Torchwood member Jack and the frozen Jack) but a fourth as [[Jack Harkness (Captain Jack Harkness)|the original user of the name]] was also present. ([[TV]]: {{cs|The Empty Child (TV story)}}/{{cs|The Doctor Dances (TV story)}}, [[TV]]: {{cs|Captain Jack Harkness (TV story)}}, {{cs|Fragments (TV story)}}, {{cs|Exit Wounds (TV story)}})

At the end of the two years missing from a younger Jack's memories, he encountered an older Jack who was investigating his history, and the pair slept together. ([[AUDIO]]: {{cs|Month 25 (audio story)}})

=== Possessions ===
[[File:145.jpg|thumb|Jack killing a Dalek shortly after it shot the Tenth Doctor. ([[TV]]: {{cs|The Stolen Earth (TV story)}})]]
When Rose and the Ninth Doctor first met him, Jack owned a small [[Chula ambulance|Chula ship]], fitted out for human use, as well as [[psychic paper]] and a store of [[nanogene]]s in the ship. When saving the Doctor and Rose by carrying a [[German]] bomb a safe distance away from London, the bomb exploded inside the ship; luckily, the Doctor and Rose saved him. ([[TV]]: {{cs|The Empty Child (TV story)}}/{{cs|The Doctor Dances (TV story)}}) 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]]. ([[TV]]: {{cs|The Doctor Dances (TV story)}}) He also managed to store a [[compact laser deluxe]] away somewhere "you ''really'' don't wanna know", in case of emergencies. ([[TV]]: {{cs|Bad Wolf (TV story)}}) During his travels with the Doctor, he modified the [[defabricator]] to be capable of destroying a Dalek. ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) As the leader of [[Torchwood Three]], Jack liked to carry a [[Jack Harkness' Webley Revolver|World War II Webley]]. ([[TV]]: {{cs|Everything Changes (TV story)}})

Jack's most significant possession was [[Jack Harkness' vortex manipulator|his]] [[vortex manipulator]], a device from his life as a Time Agent that often functioned as Jack's version of [[the Doctor's sonic screwdriver]]. Even after the time travel and teleport functions burned out, ([[TV]]: {{cs|Utopia (TV story)}}) Jack kept and continued to use the device. The vortex manipulator was fully repaired by the [[Tenth Doctor]], ([[TV]]: {{cs|The Sound of Drums (TV story)}}) but he twice disabled the time travel and teleport functions to keep Jack from having free use of time travel and teleportation. ([[TV]]: {{cs|Last of the Time Lords (TV story)}}, {{cs|Journey's End (TV story)}}) Following one of his deaths, Jack bequeathed his vortex manipulator to UNIT where it was eventually taken by [[Clara Oswald]] in order to reunite with the [[Eleventh Doctor]] in Elizabethan England. ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) By the time of Jack's reunion with the [[Thirteenth Doctor]], he had somehow managed to reacquire his vortex manipulator and repair at the very least the teleport function. ([[TV]]: {{cs|Revolution of the Daleks (TV story)}})

=== Romantic interests ===
Given his long life and Jack's comment, "If you went through my back catalogue, we'd be here 'til the sun exploded", Jack had numerous to uncountable relationships through the hundreds of years he was alive. ([[TV]]: {{cs|Day One (TV story)}}) His charismatic and flirtatious nature combined with his naturally evolved pheromones would seem to confirm this.

Although once described as [[gay]] by Owen Harper, Jack was, correctly, omnisexual, in that he found not only both human males and females attractive, but members of alien races as well. He had many lovers of both sexes and of numerous species. By nature, Jack flirted with nearly everyone he met. The earliest known example was his Time Agency partner Captain [[John Hart (Kiss Kiss, Bang Bang)|John Hart]], ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}) but Jack also recalled lovers from his Time Agency days such as his would-be executioners (a couple) and a boyfriend with no mouth. ([[TV]]: {{cs|The Doctor Dances (TV story)}}, [[TV]]: {{cs|Fragments (TV story)}}) He was considered to be sexually prolific by his Time Agency colleagues and by future norms of relationships. ([[AUDIO]]: {{cs|Month 25 (audio story)}}) When a time travelling Jack travelled back to his Time Agency era, the younger and older Jacks had sex, although the younger Jack dosed them both with [[retcon]] beforehand. ([[AUDIO]]: {{cs|Month 25 (audio story)}})

Operating as a Time Agent alongside John Hart, Jack and he made a habit of having [[sex]] together with several historical figures, namely [[Alexander the Great]], [[Catherine the Great]], and [[Christopher Marlowe]]. ([[AUDIO]]: {{cs|The Death of Captain Jack (audio story)}})

During his stint as a con man during [[World War II]], Jack had an affair with a soldier named [[Algy]]. ([[TV]]: {{cs|The Doctor Dances (TV story)}}) While travelling at their side, Jack appeared to develop romantic feelings for [[Rose Tyler]] and the [[Ninth Doctor]], [[kiss]]ing them both on the mouth upon leaving them to fight the Daleks. ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) The Doctor chose neither to encourage nor discourage Jack, though he did playfully tease Jack at one point. ([[TV]]: {{cs|Boom Town (TV story)}})

While stranded on Earth, Jack alluded to countless romances. He was known to have dated notables [[Christopher Isherwood]] ([[TV]]: {{cs|Reset (TV story)}}) and [[Marcel Proust]], ([[TV]]: {{cs|Dead Man Walking (TV story)}}) and may have had a sexual relationship with [[Alan Turing]]. ([[PROSE]]: {{cs|The Twilight Streets (novel)}}) Other mentions included acrobatic twins and the possibility of relationships with other coworkers and acquaintances, such as [[Eleanor (Golden Age)|Duchess Eleanor]]. ([[AUDIO]]: {{cs|Golden Age (audio story)}}) In 1927, Jack had a brief relationship in New York with Italian thief [[Angelo Colasanto]], whom Jack likened to being his "[[companion]]", similar to those of [[the Doctor]]. Jack left him after Angelo, and later the wider Italian-American community, attempted to kill him after Angelo was released from prison the following year. ([[TV]]: {{cs|Immortal Sins (TV story)}})

Of his more significant relationships, in the early 1940s, Jack fell in love and developed a relationship with a Torchwood coworker named [[Greg Bishop]]. ([[PROSE]]: {{cs|The Twilight Streets (novel)}}) Later in the 1940s, he had a relationship with [[Estelle Cole]] but seemingly disappeared out of her life forever one day. ([[TV]]: {{cs|Small Worlds (TV story)}}) In this period, Jack also became married — as black and white photos showed — but outlived his wife. ([[TV]]: {{cs|Something Borrowed (TV story)}}) The [[Eleventh Doctor]] implied that he knew Jack to have been married, or at least engaged several times. ([[TV]]: {{cs|The Wedding of River Song (TV story)}}) In the late 1960s, Jack met and had a brief relationship with involuntary time-traveller [[Michael Bellini]]. ([[PROSE]]: {{cs|Trace Memory (novel)}}) Later still, with Torchwood agent [[Lucia Moretti]], Jack was the father to [[Alice Carter]], who in turn produced a grandson. ([[TV]]: {{cs|Children of Earth: Day One (TV story)}}, {{cs|Children of Earth: Day Three (TV story)}}) Jack was vague when asked precisely how many children he had fathered. ([[TV]]: {{cs|Immortal Sins (TV story)}})

In the early 21st century, Jack recruited [[Gwen Cooper]], with whom he had a great deal of sexual tension. ([[TV]]: {{cs|Everything Changes (TV story)}}, {{cs|Day One (TV story)}}) Gwen ultimately chose her boyfriend [[Rhys Williams]], whom she later married. ([[TV]]: {{cs|Something Borrowed (TV story)}}) Jack had also recruited [[Ianto Jones]], with whom he developed a romantic relationship. ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}, {{cs|Fragments (TV story)}}) Despite these burgeoning relationships, Jack met the [[Jack Harkness (Captain Jack Harkness)|real Captain Jack Harkness]] after travelling back in time and the two developed a romantic bond, culminating in a [[kiss]] upon their pained farewell. ([[TV]]: {{cs|Captain Jack Harkness (TV story)}})

On [[Malcassairo]], Jack also met and was attracted to [[Martha Jones]], the [[Tenth Doctor]] and even fleetingly to the [[Malmooth]] [[Chantho]], as well as a human male refugee. ([[TV]]: {{cs|Utopia (TV story)}}) On witnessing Martha's obvious unrequited love for the Doctor, Jack commented, "You, too, huh?" showing that like with the Ninth Doctor, Jack also had feelings for the Tenth. ([[TV]]: {{cs|The Sound of Drums (TV story)}}) When he returned to Earth and John Hart departed, ([[TV]]: {{cs|Kiss Kiss, Bang Bang (TV story)}}) he began an exclusive relationship with Ianto, though he continued to flirt with everyone he met. During the Medusa Cascade incident, Jack confessed to being a fan of Sarah Jane Smith, citing specifically her triumph against the [[Slitheen family|Slitheen]], which did include some brief flirting. ([[TV]]: {{cs|The Stolen Earth (TV story)}})

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. ([[TV]]: {{cs|Children of Earth: Day Four (TV story)}}) It was also close enough for Jack to attempt to stay in the Rift after it closed forever, not wanting to live in a world without Ianto. Ianto tricked Jack into not attempting suicide, killing himself (or, technically, his spirit). Before Ianto died for the second time, though, the two finally confessed their love to each other. ([[AUDIO]]: {{cs|The House of the Dead (audio story)}})

He was later introduced to [[Alonso Frame]] by the [[Tenth Doctor]] during his [[Final reward|last farewells]] prior to [[Regeneration|regenerating]] into the [[Eleventh Doctor]]. ([[TV]]: {{cs|The End of Time (TV story)}}) However, a [[meteor shower]] forced them to separate soon after they met, having been caught up in the onslaught of [[Mother Nothing]]. ([[AUDIO]]: {{cs|One Enchanted Evening (audio story)}})

=== Relatives ===
Jack's known relatives were his father, [[Franklin (Adam)|Franklin]], his younger brother, [[Gray (Fragments)|Gray]], and [[Jack Harkness' mother|his mother]]. His father was killed during an attack on the [[Boeshane Peninsula]]. ([[TV]]: {{cs|Adam (TV story)}}) Gray later turned against his brother and was eventually cryogenically frozen in the Torchwood Hub; the Hub's subsequent destruction during the 456 incident rendered Gray's fate unclear. ([[TV]]: {{cs|Exit Wounds (TV story)}}, {{cs|Children of Earth: Day One (TV story)}})

He also had many spouses. When the [[Eleventh Doctor]] explained to [[Dorium Maldovar]] the possibilities a time machine could bring, he said he could go on all of Jack's stag parties. ([[TV]]: {{cs|The Wedding of River Song (TV story)}}) At least one of his spouses was female. ([[TV]]: {{cs|Something Borrowed (TV story)}})

On Earth he had a daughter, Melissa Moretti (later known as [[Alice Carter]]), and a grandson, [[Steven Carter]]; Steven died at the resolution of the 456 incident, and Jack's relationship with his daughter became estranged. ([[TV]]: {{cs|Something Borrowed (TV story)}}, {{cs|Children of Earth: Day Three (TV story)}}, {{cs|Children of Earth: Day Five (TV story)}})

The fact his daughter was ageing and his grandson died indicated that Jack's immortality could not be passed genetically. By this time, Jack's only known living relative was his daughter, Alice. ([[TV]]: {{cs|Children of Earth: Day Five (TV story)}})

== Behind the scenes ==
=== The Face of Boe? ===
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]], John Barrowman and [[David Tennant]] have all gone on record as saying that Jack is the Face of Boe.

While promoting ''[[Series 4 (Torchwood)|Torchwood: Miracle Day]]'', Davies insisted that the idea of Jack living to become the Face of Boe is just a conjecture, and the possibility of Jack not surviving ''Torchwood'' remained. <ref>[http://io9.com/5818770/what-the-creators-of-torchwood-miracle-day-promise-youll-see io9 - What the Creators of Torchwood: Miracle Day Promise You'll See], 6 July 2011; accessed 5 December 2011</ref>

On May 30, 2020, during the ''New Earth'' and ''Gridlock'' #NewNewYork tweetalong on Twitter, Davies officially confirmed that Jack is indeed the Face Of Boe. <ref>https://twitter.com/russelldavies63/status/1266814545793880064?s=20</ref><ref>https://twitter.com/russelldavies63/status/1266815575801696262?s=20</ref>

=== Torchwood website ===
The [[torchwood.org.uk|Torchwood website]] gave more information about Captain Jack Harkness. The series 1 version of the site, which no longer exists as of 2013, though the individual pdf files still exist on the BBC website as of then, shows a letter addressed to an undisclosed boss referring to a scam to pull diamonds away from soldiers guarding a diamond mine in 1908 Lahore, conveniently making a shipment go "missing". <ref>{{cite web |url=http://downloads.bbc.co.uk/doctorwho/torchwood/5lahore-letter.pdf |title=Letter written in Lahore |date of source= |website name=Torchwood website |accessdate= 23 July 2013 }}</ref> It also shows letters dated February 1944, June 1944 and August 2004 from Estelle Cole after they had met. In the 2004 letter, reminded of when her father told her not to bother with an address, as His Majesty would see to it being properly delivered regardless, Estelle wrote that she sent it off without an address, just a name. She had noticed that Jack, whom she spotted outside a Newport pound shop, either hadn't aged a day since his supposed death in "secret combat", or had fathered a son that was identical in appearance to "haunt" her. <ref>{{cite web |url=http://downloads.bbc.co.uk/doctorwho/torchwood/5estelle.pdf |title=Letters from Estelle |date of source= |website name=Torchwood website |accessdate=23 July 2013 }}</ref>

=== Age ===
''[[The Time Traveller's Almanac]]'' provided estimates of Jack's [[age]] across his televised appearances and other notable events. By this reckoning, he joined the [[Time Agency]] between the age of [[15 (number)|15]] and [[20 (number)|20]], left the Agency to become a [[conman]] between the age of 20 and [[35 (number)|35]], was 35 when he encountered the [[Ninth Doctor]] and [[Rose Tyler]] in [[1941]] and as late as his arrival in [[1869]] following the [[Bad Wolf Incident]]. It was at the age of [[58 (number)|58]] that Jack realised his [[immortality]] after being shot at [[Ellis Island]] in [[1892]]. Aged [[157 (number)|157]]-[[166 (number)|166]] in the [[1990s]], Jack watched over Rose at the [[Powell Estate]]. In [[2006]], Jack, aged approximately [[172 (number)|172]], was working at [[Torchwood Three]] in [[Cardiff]] whilst his younger self, aged 35, was present for the [[Cardiff Earthquake]]. Having waited [[139 (number)|139]] years for a version of the Doctor who coincided with his own [[personal timeline]], Jack, aged [[174 (number)|174]], joined the [[Tenth Doctor]] in [[the TARDIS]] before being embroiled in the [[Toclafane invasion]]. Having lived through [[the Year That Never Was]], Jack rejoined Torchwood at the age of [[175 (number)|175]]. He was [[2157 (number)|2,157]] when he and Torchwood Three were embroiled in the [[Planetary Relocation Incident]] in [[2009]].

===''Doctor Who: Legacy''===
In the story of ''[[Legacy (video game)|Doctor Who: Legacy]]'', Jack uses the [[Cardiff Space-Time Rift]] as a focal point for creating artificial [[time paradox]]s to reach [[the Doctor]]s and their [[companion]]s, joining them as they travel through time to stop and fix the damage caused by the [[Sontaran]]s' attacks throughout [[history]].

=== Other matters ===
* 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|''Doctor Who'' universe]].
* Barrowman auditioned for the role with Scottish, English and American accents. The writers decided that he use his American accent.
* Davies has said he got the surname "Harkness" from {{iw|marvel|Agatha Harkness (Earth-616)|Agatha Harkness}}, a recurring character from the ''[[Fantastic Four]]'' comic book. This is not the first time he has used the name Harkness. He used it previously in one of his earlier works, {{wi|Century Falls}}.
* 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 {{wi|The Friday Night Project}}, a late-night talk show). This bed and manhole are seen in {{cs|Small Worlds (TV story)}}.
* Jack Harkness has the distinction of being the first ongoing character in the televised ''Doctor Who'' universe to be definitely confirmed within that era as non-heterosexual. Specifically, Jack is described as omnisexual. However, in the expanded [[Doctor Who universe|''Doctor Who'' universe]] he is far from the first, as [[Seventh Doctor]] companion [[Chris Cwej]] was revealed to be bisexual in the 1996 [[Virgin New Adventures]] novel ''[[Damaged Goods (novel)|Damaged Goods]]'' (written by Russell T Davies), while [[Third Doctor]]-era recurring character [[Mike Yates]] was "outed" as [[gay]] in [[PROSE]]: {{cs|Happy Endings (novel)}} (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 (comic story)|Oblivion]]''. Companion [[Sam Jones]] was bisexual: she had [[kiss]]ed a female classmate before travelling with the Doctor ([[AUDIO]]: {{cs|Bounty (audio story)}}) and later had a long relationship with a woman named Chris. ([[PROSE]]: {{cs|Seeing I (novel)}}) Retroactively, television companion [[Adric]], from the [[Fourth Doctor|Fourth]] and [[Fifth Doctor]]'s eras, would later be confirmed bisexual in [[AUDIO]]: {{cs|A Full Life (audio story)}}, and [[Tegan Jovanka|Tegan]] and [[Nyssa]] would go on to be a couple in [[WC]]: {{cs|Farewell, Sarah Jane (webcast)}}.
* Much like [[Nicola Bryant]]'s portrayal of [[Peri Brown|Peri]] and various guest actors portraying Americans, sometimes Barrowman used word choices and pronunciations that an American wouldn't use. The most obvious example was his way of saying "estrogen" in [[TV]]: {{cs|Everything Changes (TV story)}}. (This is mainly because the word is spelt ''oestrogen'' in British English.) Unlike Peri, [[Canton Delaware]], [[Sanchez|Lt.Gen. Sanchez]], and others, however, Jack is from a distant future where those British usages may well have become the norm. He is also not actually American ''per se'', but rather a human from another planet entirely. Finally, in most of his appearances, he had lived in Britain for many decades and would presumably have adopted vernacular.
* Jack Harkness wore the rank slide of a Group Captain but has been addressed, incorrectly, as "Captain". However, in his initial appearance in ''Doctor Who'' he was incorrectly wearing the cap and insignia of a Squadron Leader.
* The [[Pete's World]] counterpart of Jack Harkness was planned to appear in the scrapped ''[[Rose Tyler: Earth Defence]]'' spin-off.
* Had [[Christopher Eccleston]] returned for [[Series 2 (Doctor Who)|season two]], Jack would have returned and the season would have focused on his missing memories. It was decided that [[David Tennant]] needed room to establish his Doctor without another, more established male companion around. Furthermore, [[Russell T Davies|Russell T. Davies]] wanted to explore the effects of the Doctor's regeneration on Rose, believing that Jack would take it in his stride.
* Jack was originally slated to appear in the [[Series 6 (Doctor Who)|''Doctor Who'' Series 6]] episode ''[[A Good Man Goes to War (TV story)|A Good Man Goes to War]]'', working with the [[Eleventh Doctor]]'s army. However, John Barrowman was unable to appear due to the filming of ''[[Series 4 (Torchwood)|Torchwood: Miracle Day]]''.<ref>[http://twitter.com/#!/steven_moffat/status/77350574932246528 Steven Moffat's Twitter feed, 5 June 2011] (broken)</ref>
[[File:Six with Jack.jpg|thumb|Jack Harkness as a companion of the [[Sixth Doctor]]. ([[GAME]]: {{cs|LEGO Dimensions (video game)}})]]
* Jack's true name has never been revealed on screen. {{as of|2020}}, the name Javic Piotr Thane has only been spoken in [[AUDIO]]: {{cs|Month 25 (audio story)}} and [[AUDIO]]: {{cs|R&J (audio story)}}.
* Harkness appears in the 2015 game ''[[LEGO Dimensions (video game)|LEGO Dimensions]]'' as a companion of all [[The Doctor|thirteen Doctors]].
* He is the first male companion to kiss the Doctor in a televised story.
* Captain Jack Harkness was set to feature in [[Doctor Who 2021 Event (comic story)|a graphic novel]] by Titan Comics, however following sexual harrasment accusations against John Barrowman, plans were shelved. <ref>{{cite web |last1=Carr |first1=Flora |title=Doctor Who graphic novel centred around Captain Jack Harkness on hold after John Barrowman allegations |url=https://www.radiotimes.com/tv/sci-fi/doctor-who-graphic-novel-john-barrowman-captain-jack-newsupdate/ |website=Radio Tmes |publisher=Immediate Media Company Ltd. |access-date=17 June 2021}}</ref> ''[[Absent Friends (Torchwood audio story)|Absent Friends]]'' was also cancelled.
