Daniel Jackson

"You are... brilliant. One of the most caring, passionate...you're the type of person who would give his own life for someone he doesn't even know. If you had one fault, it was that you wanted to save people so badly, y-you wanted to help people so much, that it tore you apart when you couldn't make a difference."

- Samantha Carter

Daniel Jackson, Ph.D., is an archaeologist and linguist from Earth, and a member of SG-1, Stargate Command's flagship team.

After his wife, Sha're was kidnapped by the Goa'uld, Apophis in 1997, Daniel reluctantly returned to Earth and later ended up joining the SGC's flagship team, SG-1 in the hope of saving her but wasn't able to do so as both she and her symbiote, Amaunet were killed by Daniel's teammate, Teal'c of Chulak in 1999.

In spite of that tragedy, Daniel chose to stay on with SG-1 up until 2002 where he ascended after being left with a lethal case of radiation poisoning.

Following his ascension, Jonas Quinn took Daniel's place with Daniel walking among the Ascended for over a year before he descended and eventually rejoined SG-1 in 2003.

As such, Daniel remains a member of SG-1 to this day and is also a veteran member of the team, having served on SG-1 longer than any of its current members which include Teal'c, Colonel Cameron Mitchell and Vala Mal Doran.

In addition to that, Daniel remains a huge asset to Stargate Command due to the fact that he is also the person responsible for deciphering and unlocking the Stargate for the United States Air Force. He is also currently the foremost expert in Ancient language and history with Dr. Meredith Rodney McKay, Chief Science Officer of the Atlantis Expedition presumably a close second to Daniel.

Background information
At age 8, Daniel lost his parents, Melburn and Claire Jackson, when they were killed in an accident at the New York Museum of Art. They were crushed while directing the moving relocation of massive stone blocks, effectively leaving Daniel an orphan. His grandfather, an archaeologist named Dr. Nicholas Ballard, being too wrapped up in his own career which largly revolved around the crystal skull he found while working in Belize, refused to adopt Daniel and as such, young Daniel was put in foster care.

As a child, his parents referred to him as "Danny."

Daniel eventually grew up to become an archaeologist, linguist and expert in ancient writing systems, languages and cultures. He worked under Dr. David Jordan at the University of Chicago and met Dr. Sarah Gardner. However, he was ostracized from the scientific community for his radical theories involving cross-pollination of ancient cultures and the Egyptian pyramids being landing sites for alien spaceships and were far older than previously thought.

He suffered from allergies and took a high dose of Antihistamines everyday to treat them. He is also afraid of heights.

1996
Since his grants had all run out and he had been evicted from his apartment, Daniel was desperate for work when he met a mysterious elderly woman named Catherine Langford; she gave him a job translating ancient Egyptian hieroglyphs for the United States Air Force. After translating the coverstone found near Giza in 1928 and realizing the symbols he could not translate were in fact constellations, he determined that they represented a six point destination. After briefing Major General W. O. West, he was shown the Stargate and he identified the seventh symbol. After dialing the address and sending a MALP, he convinced West that he could open the gate on the other side and he accompanied Colonel Jack O'Neil's team to Abydos.

After arriving on the planet and discovering a Naquadah mine and meeting the Abydonians, they were taken to the city where a feast was prepared while they waited out a Sandstorm. The Abydonian Elders sent Sha're to him as a gift but he refused and began trying to talk to her. She was able to lead him to a cave with hieroglyphs on the wall and reading the walls he began to learn the language and was able to learn about Ra. He also discovered the address to Earth but the seventh symbol was worn off. After the sandstorm hit the base camp, Ra arrived in his ship and had his Horus Guards attack the team members still in the Abydos pyramid. In the skirmish that followed, Lt. Porro and Lt. Reilly were killed while Lt. Louis Ferretti and Lt. Freeman were captured. When O'Neill, Jackson, Lt. Charles Kawalsky and Lt. Brown returned to the pyramid, they found Ra's ship overlooking it and armed themselves before entering. Kawalsky was captured and Brown was killed while O'Neill tried to arm a Mark III Nuclear warhead that he had brought along in case of threats, but found the bomb gone. Anubis and Horus came down the Transportation rings and O'Neill and Jackson were forced to surrender or die. They were taken aboard the ship where O'Neill managed to get a Staff weapon and kill one of the Horus guards, but Jackson was killed and Ra was shielded by the children that follow him and O'Neill was beaten down when he hesitatesd to fire. After Ra resurrected Daniel in his Sarcophagus, Ra explained that he was going to send the bomb to Earth with a shipment of Naquadah to increase its destruction.

The next day, Ra forced Daniel to execute his friends publicly, but a group of young Abydonians, led by Skaara and Sha're, having learned their history from the cave walls, rebelled and created a distraction, allowing him to shoot at Ra and escape with the team, though a few Abydonians along with Freeman were killed. They returned to the caves, while in the caves Daniel finds out Sha'uri and him are married. He asks Sha'uri about this marriage and states that she hasn't told them he didn't want her, yet by now Daniel has feelings for Sha'uri and kisses her saying he accepts being her husband. While talking to Sha'uri's brother he discovers the seventh symbol. The next day, the team and the rebels infiltrated the miners and O'Neill killed Horus. Jackson exposed Horus' face to the Abydonians to show them that their gods were just regular men and then the team joined the caravan that delivers a tribute of Naquadah to Ra. Jackson, O'Neill and Sha're went inside the pyramid with a few of the rebels while Kawalsky and Ferretti along with the rest of the rebels waited outside. O'Neill was revealed and started a gunfight that left two of the three Horus guards dead and all but himself. Jackson and Sha're killed the last Horus guard closed the door and shot a blast that knocked everyone outside (charging the temple) off their feet before O'Neill killed him with a staff weapon. O'Neill discovered the bomb and armed it, but before he could do anything else, Sha're was killed by a Horus guard that Jackson then killed.

Desperate, Jackson used the opportunity when Anubis ringed down to send the bomb to Earth to ring to Ra's ship and used his sarcophagus to resurrect Sha're while O'Neill fought Anubis and tried to disarm the bomb. Ra found Jackson on the rings trying to return to the pyramid and started killing him with his Kara kesh. O'Neill managed to overpower Anubis and positioned him under the rings, activating them, decapitating Anubis. On the ship, Jackson managed to break free as the rings activated and he and Sha're escaped as Anubis' head traveled to the ship. Seeing that they won, O'Neill tried to deactivate the bomb, but was unable to as Ra rigged it. Having lost, Ra left Abydos in his ship. With less than a minute left and no way to disarm the bomb, Jackson and O'Neill came up with the idea to send the bomb to Ra's ship. They ringed the bomb on board and Ra could only watch in horror as the bomb exploded, destroying the ship and killing him. After Ra was killed, Daniel remained on Abydos with Sha'uri, to be with his wife.

1997
Having lived on Abydos for one year, Daniel had no access with Earth and lived peacefully with the Abydonians. After Apophis went through Earth's Stargate, the United States government thought he came from Abydos. Colonel Jack O'Neill was able to convince Major General George S. Hammond to contact Daniel Jackson, which was successfully performed via a Kleenex box. Jackson replied back to send more, which prompted O'Neill and his team to journey to Abydos, where they were reunited with Daniel Jackson and the other Abydonians. Daniel Jackson had discovered a cartouche, which charted a vast network of Stargates across the galaxy, on Abydos, which he showed O'Neill and Captain Samantha Carter. Apophis also arrived, kidnapping Sha're and implanting her with his queen, Amaunet. Daniel was brought back to Earth and, upon his request, made a member of SG-1 with O'Neill and Carter. When he, along with SG-1 and SG-2 went to Chulak, he and his team were caught by Apophis and imprisoned. They were able to escape with help of the Jaffa Teal'c, but Daniel was unsuccessful in retrieving Sha're. Shortly after the mission on Chulak, Teal'c joined the team as well, having proved his loyalty by killing the Goa'uld inhabiting the body of Major Charles Kawalsky.

Jackson discovered that Ernest Littlefield had gone through the Stargate in 1945 and convinced Major General George S. Hammond to authorize a rescue mission. On the planet, dubbed Heliopolis, Littlefield showed Daniel a meeting hall containing information about an Alliance of Four Great Races, including a diagram that explained the mystery of life. Even though the whole structure was about collapse into the ocean, Jackson was more than a little reluctant to leave the planet.

His teammates were made to think he was dead by Nem, an Oannes, who kidnapped Daniel to discover the fate of his mate, Omoroca. Under the influence of her hypnotic breath, Daniel had sexual intercourse with Hathor in order for her to produce Goa'uld symbiotes. Though he can't have any recollection of this, having lost all his memory of what happened while he was under Hathor's control, he is rather repulsed by the knowledge.

1998
On a mission to P3R-233, Daniel discovered the Quantum Mirror and was transported to an alternate reality where he had never joined the SGC and Earth was being annihilated by Apophis. Using information from that reality which included the gate address for the location where the invasion would be launched from, SG-1 managed to prevent the same attack in their reality, simultaneously confirming the worth of the Stargate Program despite the efforts of Senator Robert Kinsey, who considered the Program to be a huge waste of money and resources.

After Jackson saved Shyla, the daughter of Pyrus, from suicide, SG-1 was imprisoned. Shyla, however, took personal responsibility for Daniel, with whom she was infatuated. Daniel became addicted to the Goa'uld Sarcophagus and experienced severe withdrawal symptoms when brought back to Earth while also displaying Daniel's darker side as he became increasingly arrogant and selfish, even turning on his teammates. He tried to escape but eventually suffered a breakdown and was returned to the infirmary. Once he was returned to his normal state, he convinced Shyla to destroy the sarcophagus.

A year after joining SG-1, Jackson and Teal'c traveled to Abydos and discovered Sha're was pregnant with Apophis' child. After the birth, Amaunet resumed control of Sha're's body having 'retreated' during the pregnancy due to the risks of causing a miscarriage and rejoined Apophis. The child, a boy, was hidden away to prevent it from falling into Apophis' hands.

1999
Some time after the successful mission that resulted in the death of the Goa'uld Setesh, SG-1 and SG-12 brought a Goa'uld artifact known as the Gift of the Gods to Stargate Command. The Gift created an alternate reality in which only the SGC existed, along with its personnel, amid nothing. Shortly after that, the SGC was attacked by a Jaffa strike force. The Tau'ri held the line, but Daniel was killed in the battle. Meanwhile, the SGC personnel in the alternate reality decided to avert the potentially disastrous effects of the Gift, which linked the Stargates of the two versions of the SGC in a manner that could destroy Earth in the main reality if the wormhole closed. The alternate Daniel Jackson removed the artifact from his reality, which was created only hours ago along with himself, with false memories, thus destroying that reality. He subsequently replaced his dead counterpart in the main universe.

On a planet where they were rescuing the Abydonians, Daniel again met Sha're/Amaunet, who had stolen back her child. However, when Amaunet used her Kara kesh on Daniel, Teal'c was forced to kill her. Daniel wakes up after being knocked out to discover his wife is dead. Not taking the news lightly, he views her body to make sure of it himself. A short time later he has visions from Sha're, one in the hospital, second at his home, and third at his house where Sha're died. After recovering from his wounds, Daniel resigns from his duty at Stargate SG-1 due to the fact he stayed on to find his wife and now that she is dead he has nothing left. In his final vision from Sha're she explains how he needed to find the child, whom he discovered was a Harcesis. They kiss one last time. At the end, Sha're is shot but in her final moments regains control over her body, saying, "I love you, Daniel," before dying. Daniel replies "I love you, too," while he strokes his wife's cheek. He then returns to his position with SG-1 to find the Harcesis.

2000
Daniel Jackson finally located the boy on Kheb and discovered the Ascended, including Oma Desala, and he left the child in her care.

Daniel was reunited with his grandfather Dr. Nicholas Ballard when SG-1 discovered a Crystal skull similar to one Nick had discovered in Belize in 1971. Nick chose to remain behind on the planet with the "giant aliens" they discovered there, so he could teach and learn from them.

When the Eurondans offered Earth their technology in exchange for heavy water, which would allow them to win a world war, Daniel Jackson protested, stating that they should find out more about the war before making the Eurondans their allies. Colonel Jack O'Neill didn't agree with him until he discovered the Eurondans were nazist.

On P3X-888, Daniel made friends with an Unas known as Chaka. When Colonel Jack O'Neill wanted to destroy a ship that was killing the Enkarans, Jackson again protested, as it would have wiped out the Gadmeer, an extinct race who were being recreated by a terraforming ship they had developed. While talking with Lotan- an artificial Enkaran created by the Gadmeer ship to communicate with the population-, Daniel was able to convince him to stop the ship's terraforming of the planet by arguing that the Gadmeer would not want to be restored to existence at the cost of another civilization. Scanning the ship's databanks, Lotan was able to discover the location of the Enkaran home world, providing his ship to relocate the population to that planet on Daniel's suggestion before it resumed the original terraforming project.

When David Jordan, an old mentor of Jackson, died, Daniel attended his funeral and was reunited with his some of his old colleagues, including his ex-girlfriend Sarah Gardner. However, Gardner was taken over by the Goa'uld Osiris, who escaped from Earth in a starship hidden in Egypt.

2001
On Abydos, Daniel again met his stepson, who he discovered had been genetically aged and was named Shifu. Jackson asked the boy for the information he possessed on the Goa'uld, but Shifu said Oma Desala had taught him to forget the information. When Daniel tried to convince him to remember it anyway, Shifu gave him a vision that showed how Daniel would have been corrupted by the knowledge of the Goa'uld with Daniel having become a ruthless, emotionless, cold-hearted power-monger who eventually had the safety of the world in his hands but he had gone to great lengths to achieve it, even alienating and killing his former friends for which he had no guilt or remorse whatsoever, suggesting that he had also developed psychopathic or sociopathic tendencies as well.

In the aftermath of Teal'c dying on Vorash, Daniel tried to offer Jack some comfort with Jack even going so far to speak to Daniel, demonstrating their strong friendship.

Later on while fleeing from Replicators who had claimed Cronus's ship, Daniel was seen firing at many Replicators, hinting that he had received training regarding military weapons and combat tactics. He, Jack and Sam later witnessed Apophis's ship crashing into Delmak.

About a year after first meeting him, Daniel's Unas friend Chaka was kidnapped by a civilization that used the Unas for slave labor. SG-1 freed Chaka, but Chaka chose to remain behind so that he could begin an Unas rebellion.

2002
When Teal'c was trapped in the Stargate, Daniel was sent to Russia to help Major Paul Davis convince the Russians give the Americans their DHD so that Carter could save Teal'c.

Jackson impersonated Yu's servant Jarren at a summit of the System Lords, where he planned to release a deadly poison that would kill the System Lords. There he again met Osiris. Osiris revealed that Anubis had returned and, realizing how powerful Anubis was, Daniel didn't carry through the Tok'ra's plan to kill off all the System Lords.

Jackson again became angry with Colonel Jack O'Neill when he killed Reese to save the base from an infestation of Replicators. Always one to see the best in humankind (or android or alien-kind), Daniel believed he was very close to persuading Reese to cease the attack, but O'Neill stated he had no way of knowing that and pointed out what would have happened if just one Replicator had escaped from Cheyenne Mountain.

"The hardest part of being who or what I am is having the power to change the things I want to change and knowing that I can't. Even when I'm certain, even when it's…absolutely clear to me, even when it affects the people I care about."

- Daniel Jackson

Daniel sacrificed himself to save the people of Kelowna from a Naquadria bomb, but the dose of radiation was lethal and he died. However, with the help of Oma Desala, he ascended. As an ascended being, Daniel found that he was not allowed to interfere in worldly matters. When Colonel Jack O'Neill was captured and tortured by Ba'al, Jackson helped in the only way he could—by offering O'Neill the opportunity to ascend himself. O'Neill rejected the offer and was eventually rescued thanks to Jackson who told Teal'c in kelno'reem how to give O'Neill a fighting chance.

2003
Jackson later appeared to Teal'c as well when he was injured, appearing in Teal'c's delusions as a psychologist who helped him to see the reality of his delusion and return to the real world in time to be rescued. In the real world, he appeared to Teal'c again to confirm that what he was experiencing now was real and he would be okay. He also observed the capture of Bra'tac and Rya'c on Erebus but was powerless to do anything about it.

When Abydos was under a threat from Anubis, he told SG-1 and they went to the planet to help. When he discovered that Anubis was ascended himself, he decided the law against interfering no longer applied and tried to stop Anubis from destroying Abydos himself. However, Oma Desala stopped him to avoid drawing the wrath of the others and Anubis succeeded in annihilating the planet.

"I think the hardest part is not knowing whether or not I—chose to be here like this. You know, whether I could be doing more good if I was still…"

- Daniel Jackson

Returned to his physical form, Daniel was found naked on the planet Vis Uban by the Nomads of Vis Uban. He had no memory of who he was, so they dubbed him Arrom, meaning "naked one," and accepted him into their society. After two months, SG-1 discovered him and convinced him to come back to Earth, where he slowly began regaining his memory. When Jonas Quinn was soon after made the Kelownan representative for the Joint Ruling Council, he left SG-1, leaving Jackson free to rejoin the team.

With the help of Teal'c, Daniel recalled his memories of Bra'tac and Rya'c's fate, which enabled a rescue mission to be mounted, simultaneously helping Daniel feel more at peace with his return to human form after his Ascension. When SG-1 were later captured by Aris Boch, Daniel was taken as a host by the Goa'uld Sobek in an attempt to access a locked chamber on Boch's homeworld, but Sebek's control over Daniel was weakened by both the chamber- created by the Ancients to contain a knowledge-draining parasite- and Sebek's own need to kep Daniel's consciousness more active than the Goa'uld preferred in order to access the subtle nuances of Daniel's linguistic knowledge. These factors, combined with his greater age and lack of a sarcophagus, eventually forced Sebek to abandon Daniel before his death, leaving Daniel relatively unharmed from his time as a host.

While on P2A-347, Daniel's body was used by a desperate engineer called Pharrin as a host for the minds of twelve dead passengers, but Pharrin eventually agreed to remove the minds from Daniel's body in exchange for a Naquadah generator to repair the Stromos. He also vouched for the Unas living on P3X-403, using Chaka as an ambassador to negotiate an alliance between Stargate Command and the Unas to mine the Naquadah on the planet to create weapons to fight the Goa'uld.

When SG-1 were briefly trapped in the time dilation of a black hole while rescuing SG-10 using stolen anti-gravity technology, Senator Kinsey was able to arrange an alliance between Earth and the Kinahhi, providing the Kinahhi with prisoners to create an Earth-based version of a monitoring technology known as the sheh-fet, unaware that this gave the Kinahhi virtual control over the SGC. Returning to Kinahhi to rescue Jack and Sam when Kinsey had them handed over to the Kinahhi for their theft, Daniel was able to make contact with the Arxanti, another group living on the Kinahhi homeworld who possessed ties to the Ancients; the sheh-fet had been created to monitor the Kinahhi cities in the belief that they were about to be attacked by the Arxanti, but the Kinahhi had faked terrorist attacks to justify the  sheh-fet' s continued existence. When the Arxanti linked Daniel up to the sheh-fet, he was able to transmit his unique insight and knowledge of the Ancients into the minds of everyone currently connected to the sheh-fet, thus confirming that the Arxanti were no threat to the general population, Jack O’Neill subsequently releasing the prisoners from the sheh-fet thanks to his more powerful Ancient gene granting him superior control over the system.

While on a mission to Honduras to recover the Ancient healing device that could be used to fight Anubis' Kull warriors, Jackson and Dr. Bill Lee were captured by local guerrillas. After being rescued from the Honduran terrorists by Colonel Jack O'Neill and CIA agent Burke, Jackson and Lee were brought back to Stargate Command.

2004
When Osiris beamed into Daniel's home and attempted to manipulate his dreams in order to locate the Lost City, SG-1 figured out what was going on and captured her. She was taken to the Tok'ra, who had her symbiote removed. Daniel told Sarah that what Osiris made her do wasn't her fault and that he would help her overcome her feelings of guilt.

When Earth's alliance with the Tok'ra and the Jaffa Rebellion broke down, Daniel tried passionately to rectify it, but to no avail. On Emmett Bregman's advice, Jackson recorded a few seconds of a mission to P3X-666. Bregman was reluctant to include this footage, which depicted the death of Dr. Janet Fraiser, in his documentary, but Daniel told him that he thought it showed "what Janet Fraiser was all about."

When Anna was discovered at a secret NID laboratory, Daniel tried to help and comfort her, although the security tapes seemed to show she was guilty of murder.

After discovering the Antarctic outpost and foiling Anubis' attack on Earth, Jackson, with the help of Dr. Elizabeth Weir, negotiated a shaky agreement with the System Lords.

He later determined the Gate address that would allow a team to reach the lost city of Atlantis. He pleaded with Brigadier General Jack O'Neill to allow him to join the expedition but was denied.

When SG-1's arrival on the planet Tegalus caused civil unrest by confirming the beliefs of a religious group, Daniel attempted to prevent a full-scale civil war from occurring. He failed and was trapped on the planet until he was rescued and Soren, a religious zealot that had taken over the Rand Protectorate, was killed. When Teal'c was trapped inside a Virtual reality pod, Daniel entered the simulation too in order to rescue him, the system being reprogrammed so that Daniel would experience a two-second 'warning' of any danger in the system so that he could help Teal'c anticipate potential threats and beat the game.

A group working for The Trust blackmailed Daniel into giving them the translation to beam aboard the Al'kesh left behind by Osiris after framing Teal'c for murder. When this group used the beaming technology on board to steal the Stargate, Jackson discovered, from Dr. Hugh Bricksdale, how to beam aboard the ship. With the help of Lt. Colonel Samantha Carter and Teal'c, he recovered the Gate, but the Al'kesh escaped into hyperspace.

On Jack's protests and insisting that they needed Daniel here, Lt. General George S. Hammond selected Daniel to accompany an expedition on the Prometheus to locate the lost Atlantis expedition. However, the ship was hijacked by Vala Mal Doran, who was planning to sell it to two prospective buyers. She had more than a passing amorous interest in Daniel, but he considered her a "fruitcake" and was more interested in regaining control of the ship. He was ultimately successful, but Vala escaped in an Al'kesh that had recently been repaired by the rest of the Prometheus's crew. The damage sustained was such that the mission had to be discontinued.

2005
When Robert Kinsey was captured by Goa'uld agents of The Trust and turned into a Goa'uld himself to trick the Russians into thinking the American administration had been overtaken by the Goa'uld, Jackson went to Russia and, with the help of Captain Daria Voronkova, he tried to prevent a nuclear war from occurring.

When Daniel was captured by Replicator Carter, he was tricked into revealing the location of the weapon on Dakara, which was the only weapon that could be used to destroy her and all the other Replicators. However, the weapon was still activated and the Replicators were wiped out, but Jackson was killed. The success of this was partially due to Daniel himself as he engaged Replicator Carter in a battle of wills and defeated her, taking control of the entire Replicator army and freezing them long enough for Lt. Colonel Samantha Carter and Jacob Carter to recalibrate and fire the weapon. Replicator Carter managed to regain control and killed Daniel by stabbing him through the heart with a sword composed from her own right hand which happened seconds before the weapon fired.

Oma Desala gave him the chance to ascend again, but he was reluctant when he learned that Anubis was planning to retake Dakara and use the weapon to destroy all life in the galaxy. Eventually, Oma decided to fight Anubis. She wouldn't be able to win, but neither would he and he wouldn't be able to do anything but fight her back. With the galaxy effectively rid of Anubis, Daniel ascended and immediately returned to his physical form.

Using a modified Puddle Jumper, SG-1 traveled back in time to Ancient Egypt to acquire a Zero Point Module. However, Ra's Jaffa found their ship, preventing them from returning to the future. SG-1 placed the ZPM in a tomb that would be discovered shortly before they left, so they would never have to go on the mission in the first place. However, the future was altered and alternate versions of the team, minus Daniel, who had been killed, traveled back in time to set things right. The Daniel Jackson of the "original" timeline lived out the remainder of his life in Ancient Egypt, but the "future" Jackson never went on the mission and remained part of SG-1.

Sometime after this, Daniel decided to leave SG-1 and join the Atlantis expedition. However, Vala Mal Doran came to Earth in search of a treasure. Daniel concluded that the Ancient who made the tablet was Merlin, and the treasure was hidden in Avalon. In order to ensure that she would get her "fair share," she bound herself and Jackson together with two Kor mak bracelets. However, she was unaware their powers would work both ways. Along with Lt. Colonel Cameron Mitchell and Teal'c, they did find Avalon hidden under a hill located in the England. There they found a Long-range communication device that Daniel and Vala used to place themselves in the bodies of Harrid and Sallis, two s living in another galaxy. Although Mitchell eventually managed to free them by throwing the device into the Unstable vortex of the Stargate, the Ori became aware of the existence of the Milky Way galaxy. Feeling responsible, Daniel decided to remain with SG-1.

During a later mission to a lab containing a laboratory that had once belonged to Anubis, SG-1 discovered a man called Khalek, who was later revealed to be the 'son' of Anubis, an evolved human possessing Anubis's genetic memory and a portion of his powers. Although Daniel argued in favor of killing Khalek, aware of the danger he could pose, the International Oversight Advisory kept him alive so that he could be studied in the hope that analysis of him would help them find a way to counter abilities like his in the field, as the Ori's Priors possessed similar powers. The research proved successful in identifying certain sound frequencies that, when broadcast, could prevent a Prior from using his abilities for a certain time, but Khalek was responsible for two deaths while he was being studied, and the SGC were only narrowly able to prevent him returning to Anubis's lab and completing his goal of Ascension.

2006
After Daniel was accidentally shifted into an alternate dimension with Lt. Colonel Cameron Mitchell and Lt. Colonel Samantha Carter, Daniel learned of a weapon designed by Merlin to neutralize the Ori. They traveled to Camelot, where they learned that the weapon in question was the Sangraal. It was also said that King Arthur and the Knights of the Round Table left to three distant lands to search for it: Castiana, Sahal, and Vagonbrei.

Daniel was presumed killed in the Battle of P3Y-229, but actually ringed over to an Ori warship, one which was carrying Vala Mal Doran. They attempted to kidnap Adria the Orici, but when that plan failed, Daniel resolved that they had to kill her, as she was "an Ori in human form". Traveling to Atlantis, he encountered the ascended Morgan Le Fay, asking her for the addresses of the planets the Sangraal might be on. All three turned up empty.

Several months later, Daniel realized that the three planets in question formed a perfect triangle in space with in the center of that triangle a point showing a fourth planet, while Vala Mal Doran realized that the address for the planet with the Sangraal was on one composed of Castiana, Sahal, and Vagonbrei's addresses. However, they had been lead there by Adria, who needed Daniel to find the weapon. It was learned that Morgan Le Fay was not protecting the Sangraal, but Merlin, who was in stasis. However, Merlin's body had deteriorated too much during that time, and his memories were downloaded into Daniel. Daniel managed to build to phases of the Sangraal, but was soon captured by Adria, with SG-1 being forced to leave him behind.

2007
While Adria's prisoner, Daniel was seemingly swayed to become a Prior, but he actually hoped to complete the Sangraal and send it to the Ori home galaxy, Merlin's downloaded personality protecting Daniel's mind from Adria's influence. After allowing himself to be captured by SG-1, he tried to convince them and Major General Jack O'Neill that he was still on their side, and gave SG-1 intelligence to capture the Ori warship carrying the incomplete Sangraal, but used O'Neill to hijack the Odyssey. Daniel redirected the Ori ship through the now deactivated Supergate, destroying the Ori before a "kill switch" Merlin had implanted during the original download caused Daniel's body to revert to its original state. However, more Ori warships were able to come through as a result.

Sometime in 2007, Daniel recruited Dr. Nicholas Rush to the Stargate program, and to work on the Icarus project.

Some time after this, Daniel began to have visions of what appeared to be Merlin - although it was later revealed to be Morgan Le Fay - alerting him to the existence of the Ark of Truth, a device that, when activated, would make anyone who looked into it believe that the Ori were not gods. Guided by his visions and with the help of Tomin, Daniel, Vala Mal Doran and Teal'c were able to discover the Ark, although they were subsequently captured and taken to the City of Celestis, where they learned that the now ascended Adria was the sole Ori left. Having activated the Ark, Daniel and Teal'c arranged for the Doci to look into it, his newfound disbelief in the Ori subsequently being 'transmitted' to every other Prior in the galaxy due to the link between them and their staffs. With Adria now weakened, Morgan attacked her, the two engaging in eternal battle much like Oma Desala and Anubis.

2008
Over a year after the fall of the Ori, around the time Atlantis rescued Teyla Emmagan and Colonel Samantha Carter returned to the Milky Way, Daniel went with SG-1 to the extraction ceremony of the last Ba'al clone. Along with SG-1 and General Jack O'Neil, they watched as the last Ba'al clone was killed and the host was being helped by Vala. Daniel then returned to the SGC and wondered about what Ba'al had meant about his plan and such with Colonel Cameron Mitchell.

A couple of months later, Daniel traveled to Atlantis to carry out research on the renegade Ancient scientist Janus. With the aid of Dr. Meredith Rodney McKay Daniel discovered Janus' lab, but the two of them were captured by the Vanir - a renegade group of Asgard who had long ago split away from the rest of their people - and forced to activate a forbidden weapon created by Janus called the Attero device, which destroyed Wraith ships currently in hyperspace at the cost of simultaneously destroying every active Stargate in the Pegasus galaxy. Having discovered that the alien race were a group of Asgard who had long since cut off contact with their brothers, Daniel and McKay were able to shut down the Attero Device using the Asgard's Armored exoskeleton, although Daniel was injured in the attempt and subsequently sent back to Earth after Atlantis' Stargate - which had been destroyed when the device was activated - was replaced.

2009
By 2009, Daniel hosted a series of videos in order to provide a crash course of the Stargate program to those who just been cleared to know of its existence. It is unknown exactly how many videos he helped to create, but it was at least six.

A short time later, Daniel tailed Dr. Nicholas Rush, who tried to infiltrate the Lucian Alliance in Colonel David Telford's body. Unfortunately, Rush's cover was blown and he was unable to call in the strike team before Commander Kiva and her team could board a Tel'tak. Later, he briefed Colonel Everett Young and Lt. General Jack O'Neill on Kiva. He objected to Young's intention to force Telford to talk by any means necessary.

Alternate realities

 * In the alternate reality that the Daniel Jackson of our reality visited in 1998, Daniel refused Catherine Langford's offer to work on the Stargate. She commented that he was "quite rude" when rejecting the offer. Catherine and her team nevertheless determined how to operate the Stargate and Jack O'Neill led the first mission through the Stargate to Abydos. As of 1997, he was living in Egypt, where he was probably killed in the Goa'uld invasion of his Earth.
 * In another alternate reality, Daniel Jackson never became involved with the Stargate Program. It was Doctor Samantha Carter who discovered how to activate the Stargate in 1995. His fate is unknown.
 * An alternate version of the SGC, along with Daniel Jackson, was created by the Gift of the Gods. This Daniel is actually the one who has been in SG-1 since 1999, as he left his reality after his counterpart who was born in the main universe died in a subsequent Jaffa attack on the SGC.
 * In 2006, an alternate version of Daniel Jackson came to our reality in an attempt to steal a Zero Point Module from Atlantis and return it to their reality to use in securing their Earth from an Ori attack. When the original SG-1 took steps to stop additional SG-1s from arriving, the alternate SG-1 gained control of the Prometheus and set course for Atlantis. Eventually, the original Mitchell outsmarted his counterpart and his team was captured. The original SG-1 was able to use the alternate SG-1's methods to send the various SG-1s back to their own realities. This version of Daniel likewise defeated Anubis with the assistance of Oma Desala in 2005.
 * In another alternate reality, Daniel was a member of an SG-1 - which consisted of Cameron Mitchell, Doctor Janet Fraiser and Martouf/Lantash - who became stranded in our reality in 2006. In their reality, Earth was attacked by the Prior virus, though the team was given the anti-virus to combat it, since our reality had already combated the plague. In this reality, Brigadier General Jack O'Neill was still the commanding officer of Stargate Command. In 2004, he assisted Dr. Fraiser in stabilising Senior Airman Simon Wells on P3X-666 and managed to get them all out safely. In our reality, this mission resulted in Janet's death.
 * In another alternate reality, Daniel was a member of an SG-1 who wore Blue Digital Tiger Stripe uniforms. In 2006, he and his team were under heavy fire and ended up in our reality. Shortly afterwards, they were examined in the infirmary. Eventually, this SG-1 were sent back to their own reality.
 * In another alternate reality, Daniel was a member of an SG-1 who wore Digital Woodland USMC MARPAT uniforms. His teammates were Samantha Carter, Cameron Mitchell and Teal'c, who was still bald in this reality. In 2006, he and his team were under heavy fire and ended up in our reality. Shortly afterwards, they were examined in the infirmary. Eventually, this SG-1 were sent back to their own reality.
 * In another alternate reality, Daniel was a member of an SG-1 who wore Hazmat suits. In 2006, he and his team ended up in our reality but were eventually sent home to their own.
 * In another alternate reality, Daniel was a member of an SG-1 who wore green jungle fatigues. In 2006, he and his team ended up in our reality but were eventually sent home to their own.
 * In the alternate reality to which Lt. Colonel Samantha Carter was accidentally transported in 2007, Major Evan Lorne stated that Daniel had been taken prisoner by the Ori several weeks prior to her arrival. The same fate had befallen the Daniel of our reality at approximately the same time. While the Daniel of our reality became a Prior of the Ori during his captivity and had Merlin's consciousness transferred into his body, it is unknown if the same was true of the Daniel of this reality.

Alternate timelines

 * In an alternate timeline, Daniel Jackson, along with Teal'c, learned about the sterilization of the Earth's population by the Aschen from Dr. Janet Fraiser and Samantha Carter. Later, they were able to convince Jack O'Neill to help with their plan to prevent it from ever happening. When the plan was put into motion, Daniel covered O'Neill while he tried to send a note through the Stargate. After O'Neill was killed, Daniel made his attempt, but was also killed by the automated defense system.
 * In another alternate timeline created by Shifu in a realistic dream, Shifu gave Daniel his genetic Goa'uld knowledge. With his knowledge, Daniel unofficially took command of the Stargate Program and began designing anti-Goa'uld satellites, known as AG-3's. His personality also began to develop into a more ruthless and cruel one. When planning the construction, Daniel forbade informing the Russians or the Tok'ra of the construction, completely breaking the treaty between Russians and Americans. Jackson took a much greater interest in Goa'uld technology and wished he could use it. One year later, the AG-3 satellites were finally ready and much had changed at Stargate Command. Colonel Jack O'Neill was apparently retired because his presence in the SGC wasn't necessary anymore and Daniel thought he was jealous. Major Samantha Carter had become a protestant against the AG-3 satellite program and believed that Jackson intended to take over the world. Something mysterious happened to Teal'c as well 1 year ago during his mission. Shifu was living with Daniel. Major General George S. Hammond was unmentioned. After another confrontation, Carter was finally arrested and pleaded that O'Neill kill him. When the long-awaited day came, Jack went to see Daniel, who took him to an underground complex which served as Jackson's main base of operations. After the success of the satellites, the Russians became angry and sent weapons to destroy the satellites. The AG-3 system easily destroyed them and the Chairman of the Joint Chiefs, General Vidrine advised to take out their launch sites. In a "wish to prevent a global nuclear war", Jackson boldly overrode the command of the satellites and took control over the AG-3 system. He cut off communication with Vidrine and targeted Moscow. Jack tried to shoot him, convinced his friend was gone, but the bullets bounced off the Goa'uld shield. Moscow was destroyed and Daniel triumphed... until the dream ended.
 * In another alternate timeline created through accidental interference by SG-1, Dr. Daniel Jackson taught English as a second language after he was disgraced in the archaeological community following the publication of his theories. He, Samantha Carter and Jack O'Neill (who first didn't come) were called into Stargate Command because of a tape which contained the recordings of the original SG-1. He claimed to always believe that something was wrong with his life. Daniel, Carter, and O'Neill, Major Charles Kawalsky and a few soldiers traveled to Chulak to recruit Teal'c. He was tortured by Apophis and then implanted with a Goa'uld. The Goa'uld pretended to still have bad vision, but Teal'c sensed the Goa'uld and subsequently killed him. In this version, Daniel had a different-styled long hair and wore glasses which were completely different from the original Daniel's (although similar to the new pair of glasses Daniel later gets). He has worse eye-vision than the original timeline's one (in the later seasons, Daniel uses his glasses much less and apparently sees fine although he could have been in an unmentioned eye operation).
 * In an alternate timeline created by SG-1 traveling back in time to retrieve a ZPM, Daniel was the only survivor of a failed rebellion that killed the rest of the team. In 2995 BC, he led a successful rebellion that drove Ra from the planet, but he stole the Stargate, changing the future. As a result, Daniel created a tablet and left it where the Stargate was supposed to be buried, knowing his future self would be able to translate it and use it to fix history.
 * In alternate timeline created by the original SG-1 traveling back to retrieve a ZPM, Daniel was the only survivor of the team when their attempted rebellion failed. He remained in the past for five years, gathering support and planning the real rebellion he knew would happen. However, an alternate SG-1 arrived to inform him that while the rebellion succeeded, Ra fled with the Stargate and Daniel was forced to change the plan so the alternate team could use the Time Jumper to hide the Stargate from Ra. In the aftermath of the rebellion, Daniel, changing his name to Danyel, became a scribe in Pharaoh Hor-Aha's court and joined the team for a final mission through the Stargate to Abydos three years later to procure Teal'c a new symbiote. This drew the attention of Ra, but with the help of the current SG-1, Doctor Carolyn Lam, the granddaughter of an Ancient named Ai and Egeria, Danyel was part of another successful rebellion that drove Ra from the planet once more. Despite being offered the chance to return to the future, Danyel chose to remain in the past as he felt at home there as did all of the alternate SG-1.
 * In another alternate timeline created by Ba'al, Daniel was a reclusive archaeologist living in Cairo, Egypt in 2008 who had been ridiculed for his theories that the pyramids were built as landing sites for alien spaceships. He wrote a book containing these theories entitled The Truth About the Pyramids, which the Daniel of the original timeline bought at Tlostart Crow Books at a 70% discount. In Major General Henry Landry's words, this version of Daniel was "a discredited whack-job living on the fringes of society." When the original Daniel arrived in that timeline, he called his counterpart and told him that all of his theories were true but the alternate Daniel hung up, thinking that the original Daniel was making fun of him. The original Daniel lost his left leg due to frostbite in the Arctic and he was killed during the final confrontation with Qetesh's Jaffa. This timeline was erased after SG-1 discovered the Solar observation outpost on Praxyon that Ba'al used to travel in time and Cameron Mitchell used it to travel to 1929 and set history back on course.

Ascension
After achieving Ascension, Daniel gained the abilities of an Ascended Being:
 * Energy Form: While Ascended, Daniel usually took the form of a spectral being made of glowing energy.
 * Tangible Form: At times, Daniel was able to appear to his friends in a tangible form.
 * Invisibility: As an Ascended Being, Daniel was invisible to those on the mortal plane unless he so chose to appear to them.
 * Ascension of others: Daniel possessed the ability to Ascend others who were willing, something he offered to do for Colonel Jack O'Neill.
 * Dream Walking: Daniel was able to enter the dreams of others for various purposes. He first used this to subtly plant an idea in Teal'c's mind of how to save Jack O'Neill and later to help Teal'c in the guise of a psychiatrist in his dream world following the Ambush of Kresh'ta.
 * Energy Manipulation: Daniel displayed the ability to create orbs of energy that are indicated to have been capable of destroying the partially-Ascended Anubis.

Residual abilities from Ascension
Following his Deascension, Daniel displayed a few residual abilities from his time as an Ascended Being:
 * Instinctual Knowledge of the Ancient language: Following his return from Ascension, Daniel possessed an immediate understanding of the Ancient language even when memory-less and thus without the knowledge of the pre-Ascension Daniel. When looking over a translation based on his pre-Ascended self's work, the amnesic Daniel noted that he had been "way wrong" with his interpretation after gaining this new instinctual knowledge of the language.
 * Knowledge of the Ancients: As discovered by Replicator Carter, Daniel possessed within his subconscious mind the collective knowledge of the Ancients, but lacked the ability to access it due to the limitations of the human mind. It is unknown if he still retains this following his second Ascension and return.
 * Telepathy: While being mind-probed by Replicator Carter, Daniel was able to use the knowledge of the Ancients she was accessing to read her mind and later enter it himself through the connection she established between them through the Replicator mind probe.
 * Replicator Collective Control: Using the Ancient knowledge exposed by Replicator Carter, Daniel was able to enter Replicator Carter's mind and take control of the entire Replicator collective, forcing every Replicator in existence to freeze in place. However, as a human, Daniel lacked the endurance to maintain this control for long.
 * Ascended Being Recognition: Following his Ascensions, Daniel displayed the ability to see through an Ascended Being's various illusions and recognize them for what they really were.

Merlin/Prior
While containing Merlin's consciousness and as a Prior, Daniel gained several near ascension abilities temporarily:
 * Access to all of Merlin's knowledge: As a result of having Merlin's consciousness in his body, Daniel gained access to all of his knowledge and memories and was able to utilize this to build a new Sangraal. Before becoming a Prior, using Merlin's knowledge in this way was very draining to Daniel. He was able to use this knowledge to grant the Odyssey a cloak presumably based on Lantean technology with the help of the Odyssey's new ZPM.
 * Telekinesis: While possessing Merlin's mind, Daniel was able to cause a water bottle to fly into his hand purely on instinct. As a Prior, he displayed a greater level of telekinetic ability, flinging people around with only a glare and pinning Richard Woolsey to a wall with no apparent effort.
 * Nature Control: While possessing Merlin's consciousness, Daniel was able to cause lightning to strike from overhead clouds and kill Ori soldiers. However, this left him drained.
 * Energy Manipulation: While containing Merlin's consciousness, Daniel was able to project a beam of energy in order to hold Adria's own energy attack back. However, he was not able to hold this for long and was left drained of energy after just a couple of minutes. As a Prior, Daniel retained this ability and used it to blast through Adria's personal shield and stun her while using a Prior disruptor to block her powers. However, breaking through Adria's personal shield required a great deal of energy from Daniel who was close to reverting to human and left him near-unconscious.
 * Technopathy: After becoming a Prior, Daniel displayed the ability to take mental control of various systems. Using this, Daniel was able to take control of the Odyssey and an Ori warship. He was also capable of dialing the Supergate with this ability.

Personality and traits
A civilian, Daniel often prefers using peaceful methods over violence which has often had him clashing with the other Stargate Command members who are part of the military including Lt. General Jack O'Neill. ,

In recent years, since returning from Ascension, Daniel has retained his original sense of justice but has often displayed a lack of patience and has even gained a willingness to resort to military tactics, which is demonstrated when he suggests that they kill Khalek instead of preserving him for the sake of studying him (although this can be attributed to his personal experience of Ascension and Anubis making it clear to him that there is no other way to contain Khalek).

In addition, Daniel has also developed something of a deadpan, almost sarcastic sense of humor.

Despite being calm and the voice of reason for SG-1, Daniel is by no means a pushover or someone who can be simply underestimated. He can easily fight back and has even shown that his mental will is far stronger than anyone else's which is shown when he goes up against Replicator Carter.

This is also demonstrated by his use of a pistol, rather than a standard MP5 or P90 in most of his career with SG-1. Despite this, he eventually became capable with such weapon as seen during the battle with the Replicators on Cronus' Ha'tak and the rescue of Colonel O'Neill and "Lieutenant Tyler" from Jaffa, demonstrating training in small team tactics. When he first believed Vala to be a dangerous Kull warrior on their first meeting, he showed no hesitation in trying to kill the intruder with a modified P90 on his own.

Due to his wife, Sha're being taken as a Goa'uld host, Daniel has developed something of a strong grudge against all Goa'uld. This is evident when he shoots a tank containing infant Goa'uld symbiotes despite Sam warning him not to do so, stating that if he did do it, then they would be no better than the Goa'uld themselves.

Relationships
Coincidentally, perhaps even ironically, most of Daniel's relationships have at some point or another been used as hosts for a Goa'uld, a fact that Colonel Frank Simmons attempted to exploit to accuse Daniel of sympathizing with their enemies when questioning him. The only definitive exception to this rule is Leda Kane, as Ke'ra (as Linea)- committed crimes that were apparently on part to those committed by the Goa'uld, and Shyla was under the indirect influence of Goa'uld technology during their relationship.

All three of Daniel's most notable romantic interests have been hosts: Vala Mal Doran was a host to Qetesh some years before she met Daniel, while Dr. Sarah Gardner and Sha're were taken as hosts by Osiris and Amaunet respectively (although it is important to note that in both cases, their relationships with Daniel were coincidental). A young Jaffa called Nesa even developed a crush on Daniel, although she never possessed a symbiote herself as she was too young at first and was instead put on Tretonin when she reached the age of Prim'ta.

Sarah Gardner
Dr. Sarah Gardner was Daniel's college girlfriend. The two broke up when Daniel was more focused on his research, to the point of forgetting their two-month anniversary. In 2000, they were reunited at the funeral of Dr. David Jordan, Daniel's old professor, but Sarah was subsequently taken as a new host for the long-trapped Goa'uld Osiris when the canopic jar that had been holding Osiris was broken while it was being taken to the museum. She remained a host for three years serving under the returned Anubis until Daniel managed to save her.

Sha're
Although Sha're was given to him as a 'gift' upon the team's first visit to Abydos, Daniel quickly bonded with Sha're, remaining on Abydos after the mission to live with her. A year later, however, Apophis' forces attacked the planet and Sha're was taken as a host for Amaunet, Apophis's queen. The two were briefly reunited when Amaunet withdrew from Sha're's mind when Apophis and Amaunet attempted to conceive a Harcesis, with Sha're returning to Abydos so that the child could be safe, but they were separated again when the child was born and Amaunet regained control. Daniel finally lost her when Teal'c was forced to kill Amaunet as she attacked Daniel with a Kara kesh, although Sha're was able to use the mental link created by the device to say goodbye to Daniel before she died, asking him to not blame Teal'c.

Hathor
Hathor was Goa'uld queen that used her pheromones to seduce Daniel and use his DNA to create a new breed of Goa'uld, but the resulting symbiotes were subsequently destroyed by Captain Samantha Carter and Dr. Janet Frasier before Hathor fled through the Stargate.

Shyla
Shyla was a Princess Daniel saved from committing suicide in 1998. She seduced Daniel by taking advantage of his somewhat-delusional state of mind after he was convinced to repeatedly use a Sarcophagus while trying to save his friends from the Naquadah mines; the relationship ended after Daniel was cured of his addiction.

Ke'ra
Ke'ra, formerly known as Linea, the 'Destroyer of Worlds', her past and knowledge of her crimes was erased when her latest experiment in biological warfare resulted in her and the population of the planet she was on at the time regressing back to the prime of their adult lives and losing virtually all of their memories. Ke'ra and Daniel developed feelings for each other, but after Ke'ra took the drug to restore her memory, the mental strain caused by who she was as Ke'ra and who she'd been as Linea proved too traumatic for her, and her memory was again erased for the safety of her and others.

Leda Kane
Leda Kane was a native of Tegalus in the Rand Protectorate. Leda cared for Daniel after her country was devastated in an attack, the two forming a deep relationship due to Leda's currently-poor relationship with her husband Jared Kane. She was killed a year later during the Ori invasion as one of the victims of the Priors' plague.

Vala Mal Doran
Although Daniel initially met Vala Mal Doran when Vala tried to steal the Prometheus, they have developed an interesting relationship since then during such occasions as their time trapped in the Ori galaxy after activating the original Long-range communication device, Daniel trusting Vala when nobody else had shown her such faith in the past. Although he tends to dismiss her flirtation as nothing serious in the main timeline, considering her merely a frustrating friend, the two had a relationship while trapped on the Odyssey, but it is unclear if this will ever take place in the main reality.

Samantha Carter
Carmen Argenziano, who plays Jacob Carter, once noted in an interview that he favored the idea of a relationship between Samantha Carter and Daniel Jackson; given their mutual intellects, coupled with the fact that Carter has also served as a Goa'uld host - albeit in the form of the Tok'ra, Jolinar of Malkshur - continuing Daniel's 'curse' without falling directly victim to it, the idea of a relationship between them is not as implausible as it might be. Even without a romantic relationship, Sam and Daniel continue to be close friends, the two often collaborating to solve some of the scientific mysteries they come across on their missions, Sam determining how their discoveries work after Daniel determines their mythological origin or translates their instructions.

Jack O'Neill
Jack and Daniel have a great respect for one another, despite their differences. Ever since the mission to Abydos, they have been on a first name basis, even after Jack was promoted. Although their relationship became more strained after Jack lied to Daniel during his undercover operation and ignored Daniel's advice during a crucial mission, in the aftermath of Daniel's Ascension they became closer once more, Daniel commenting that he was essentially Jack's best friend when talking with an alternate version of Jack. Spacemonkey is the nickname of Daniel Jackson, given by Jack O'Neill.

Teal'c
Although Teal'c was responsible for the abduction of Sha're, Daniel's wife, while he was still a servant of Apophis, and later her death, Daniel was eventually able to forgive Teal'c for his actions, recognizing that Teal'c had only been doing his duty at the time. They became loyal friends during their time on SG-1; when Daniel was dying of radiation poisoning, Teal'c stated that Daniel's death would not only cost them a great warrior against the Goa'uld, but would also deprive him of a great friend.

Sam Carter
Daniel and Sam have a strong, bidding friendship and a deep respect for each other.

Rodney McKay
Initially Daniel and Rodney seemed to have a friendly rivalry with each other, with McKay less than thrilled that he had to put aside his research to accommodate Daniel's search for Janus lab. However, once the lab was discovered and they were subsequently abducted by the Vanir, they began to develop a much more cooperative relationship. By the time they deactivated the Attero Device, they had a solid working relationship with a mutual respect for each other. (ATL: "First Contact", "The Lost Tribe")
