Former members


SG-1 was one of the initial teams formed during the founding of Stargate Command. Their first mission was to go to Chulak with SG-2 to gain information on the Goa'uld and attempt a rescue of Sha're and Skaara. They went to Chulak City but were captured by Apophis. O'Neill convinced Teal'c, the First Prime of Apophis, to help him free the other prisoners and he turned against his fellow Serpent Guards. After returning to Earth, O'Neill recommended that Teal'c join SG-1. (SG1: "Children of the Gods") After Teal'c helped stop the Goa'uld that had taken over Major Charles Kawalsky from escaping through the Stargate, he was allowed to join SG-1. (SG1: "The Enemy Within") While on a mission to P3X-797 with SG-3 the human members of the teams became infected with the Touched virus but luckily a cure was developed which SG-1 helped distribute on P3X-797. (SG1: "The Broca Divide")

When communication was lost with SG-9, SG-1 was sent to locate them, finding that the team's commander Captain Jonas Hanson was ruling over the local population as a god; they eventually convinced the people that he was not a god and helped activate a force field over part of the planet to protect the people from intense radiation. (SG1: "The First Commandment") SG-1 made contact with the Nox and intended to try to make contact with the Asgard, resulting in O'Neill and Teal'c being trapped in the Labyrinth on Cimmeria and having to destroy Thor's Hammer to get Teal'c out. (SG1: "The Nox", "Brief Candle", "Thor's Hammer") The team was joined by Catherine Langford to find her former fiance Ernest Littlefield who went through the Stargate in 1945 and found proof that the Stargate was not built by the Goa'uld. (SG1: "The Torment of Tantalus")

The team was taken by the Oannes Nem who gave fake memories of Daniel Jackson's death to the rest of the team in order to find out what had happened to his mate Omoroca; the team eventually learned the truth and went back for Jackson. (SG1: "Fire and Water") While visiting Cartago Teal'c is accused of murder and put onto trial and the rest of SG-1 served as his defenders. (SG1: "Cor-ai") They went to a planet in the middle of volcanic eruptions and rescued several Tollans, later helping them escape through the Stargate to join the Nox. (SG1: "Enigma") On a mission to P4A-771 they came under attack and the Stargate was struck by energy weapons fire and overloaded sending O'Neill and Carter throught the Stargate hidden in Antarctica. (SG1: "Solitudes") The Altairan Harlan stunned SG-1 when they came to Altair and created synthetic duplicates of the team. (SG1: "Tin Man")

While on a mission on P3R-233 Jackson disappeared and the team had to bring in help to find him; when they did he warned them that the Goa'uld were coming to Earth after witnessing a similar event in an alternate reality. The team joined Major General George Hammond in briefing Senator Robert Kinsey on the importance of the SGC after Kinsey decided to cut their funding completely; Kinsey was unmoved even after being told of the incoming attack. Deciding that they had to do something about the attack, SG-1 went through the Stargate without authorization and boarded a ship headed for Earth. After being captured they teamed with Bra'tac to destroy both of the ships sent to Earth. (SG1: "There But for the Grace of God", "Politics", "Within the Serpent's Grasp", "The Serpent's Lair")

SG-1 helped evacuate the Nasyans from their world when they were attacked by the Goa'uld and were then tasked with trying to find a new world for them to go to. (SG1: "In the Line of Duty") The team helped a man who was running from someone and were tried for murder alongside him, being sent through the Stargate to the prison planet Hadante. They made friends with Linea who was able to provide them with a power source to manually dial out the Stargate and escape. (SG1: "Prisoners") SG-1 were pulled into Virtual reality chairs and forced to relive some of their traumatic pasts, they eventually escaped and allowed the other people in the chairs to reclaim their world. (SG1: "The Gamekeeper") The team was captured on P3R-636 and put into the mine and the Princess Shyla took an interest in Jackson who eventually negotiated for their release. (SG1: "Need")

When it was discovered that the Goa'uld had invaded Cimmeria, SG-1 returned to help free the Cimmerians. They made contact with Thor and he arrived to remove the Goa'uld presence from the planet. (SG1: "Thor's Chariot") They brought back an Orb from P5C-353 which anchored itself with spikes in the gateroom and began releasing an organism throughout the base. (SG1: "Message in a Bottle") SG-1 returned to Chulak to free Teal'c's son Rya'c from Apophis, bringing him back to Earth. (SG1: "Family") O'Neill and Carter attended an award ceremony while Jackson and Teal'c went to Abydos and were later reunited when O'Neill and Carter arrived to find that Heru'ur had come to the planet and they fought him and his forces. (SG1: "Secrets")

While exploring BP6-3Q1, Teal'c was stung by an alien insect which began to change his DNA. (SG1: "Bane") SG-1 went in search of the Tok'ra and made contact with them but were unable to offer anything of value to the Tok'ra so they refused to form an alliance and told them that they would remain as their guests while the Tok'ra searched for a new base location. When SG-1 helped them discover a spy, helped them evacuate their base and provided a host for a dying Tok'ra, they were thankful of SG-1. (SG1: "The Tok'ra, Part 1", "The Tok'ra, Part 2") O'Neill was injured so the rest of SG-1 had to go to PXY-887 to locate SG-11. The team came back with SG-11, who were actually aliens pretending to be SG-11. (SG1: "Spirits") SG-1 went to Madrona and were shown the Touchstone, they returned to examine the Touchstone again but it had been stolen. They returned to Earth to help find it, discovering that someone had used the second Stargate to go to Madrona to steal it.

(SG1: "Holiday") After receiving a set of coordinates, SG-1 went to a planet thinking it was the Tok'ra trying to contact them but a Death glider crashed and they found Apophis aboard. (SG1: "Serpent's Song") The team went to PJ2-445 where they encountered some strange aliens that began to fall ill.

They located the Stargate but were accidentally sent forward decades past the time they wanted; they were sent back by Cassandra. (SG1: "1969")

They were captured by Hathor who left Teal'c behind and took the others into a fake SGC, pretending that they had been frozen and awoke in the year 2077.

(SG1: "Pretense") The team visited P4X-884 but had no memory of going to the planet and it was found that they had small devices installed in their brains. The devices allowed them to communicate with the artificial intelligence Urgo who increases their senses to gather information from their experiences.
