Many of the characters are members of alien species discovered while exploring the galaxy through the [[Stargate (device)|Stargate]], although there are an equal number of characters from offworld human civilizations. While ''Stargate SG-1'', ''[[Stargate Atlantis]]'' and ''[[Stargate Universe]]'' are separate shows, they take part in the same [[fictional universe]], so no character is internally show-specific.
==Main characters== Except for the commanders of the top-secret [[Stargate Command]] military base (SGC), all main characters of ''Stargate SG-1'' are members of the SG-1 team, the primary unit of the SGC in the show. SG-1's duties include [[First contact (science fiction)|first contact]], [[reconnaissance]] and combat, diplomacy, initial [[archaeology|archaeological]] surveying, and technological assessment. The composition of SG-1 changes several times during the series run and varies in several [[Parallel universe (fiction)|alternative universes]].<ref>In Season 3 Charles Kawalsky was included. Alternative teams in Season 9's "[[Ripple Effect (Stargate SG-1)|Ripple Effect]]" include [[Martouf]] and [[Janet Fraiser]]. Season Ten's "[[The Road Not Taken (Stargate SG-1)|The Road Not Taken]]" includes reference to an SG-1 commanded by [[Lorne (Stargate)|Major Lorne]].</ref>

===Daniel Jackson=== {{main|Daniel Jackson (Stargate)}} Dr. Daniel Jackson is a brilliant [[archaeologist]] and [[linguist]], specializing in [[Egyptology]], whose unusual theories concerning the origin of the Egyptian Pyramids led to his participation in the original mission through the stargate in ''[[Stargate (film)|Stargate]]''.

He also appears in both direct-to-DVD films and in seasons 1 and 5 of ''Stargate Atlantis''. Daniel joins the SG-1 team in search of his kidnapped wife (Sha're), until she dies in season 3. However, he decides to remain a part of SG-1, and does so until his [[ascension (Stargate)|ascension]] at the end of season 5. Following his decision to retake human form, he rejoins SG-1 at the beginning of season 7.
As stated in season 2's "[[1969 (Stargate SG-1)|1969]]", Daniel speaks 23 languages, including Russian, German, Spanish, and [[Egyptian language|Egyptian]]. Throughout the run of the series, he becomes Earth's foremost expert on the [[Ancient (Stargate)|Ancients]], and also learns many alien languages, such as [[Goa'uld#Language|Goa'uld]], [[Ancient (Stargate)#Language and writing system|Ancient]], and [[Unas (Stargate)|Unas]].
===Samantha Carter=== {{main|Samantha Carter}} Samantha "Sam" Carter is an astrophysicist and [[USAF]] captain (later major, lieutenant colonel, colonel, then brigadier general).

Teal'c states that he is 101 years old in season 4's "[[The Light (Stargate SG-1)|The Light]]", and ages an additional 50 years in season 10's "[[Unending]]". His catchphrase is "Indeed". Teal'c's most notable feature is a golden tattoo on his forehead, a sign that he once served the Goa'uld [[Apophis (Stargate)|Apophis]] as First Prime, the highest Jaffa rank. His interaction with [[Bra'tac]] (Apophis' former First Prime) and his own personal experiences led him to doubt the divinity of the Goa'uld.
Teal'c defects from Apophis in the pilot episode and joins the SG-1 team, believing this to be an opportunity to eventually defeat the Goa'uld and bring freedom to all Jaffa.<ref name="Children of the Gods">"[[Children of the Gods (Stargate SG-1)|Children of the Gods]]"</ref> He leaves his wife [[Drey'auc]] and his son [[Rya'c]] behind on Chulak.

Teal'c and Bra'tac lose their symbiotes after a sabotaged rebel Jaffa summit in season 6's "[[The Changeling (Stargate SG-1)|The Changeling]]", but the [[Tok'ra]] drug Tretonin can sustain them and eventually becomes instrumental in liberating Jaffa from physiological reliance on Goa'uld symbiotes,. Teal'c and Bra'tac eventually lead the Jaffa to victory over the Goa'uld in season 8's "[[Reckoning (Stargate SG-1)|Reckoning]]"/"[[Threads (Stargate SG-1)|Threads]]". Teal'c is chosen as a member of the new [[Jaffa High Council]] and supports Bra'tac as an interim leader in season 9's "[[The Fourth Horseman (Stargate SG-1)|The Fourth Horseman]]" before a type of government is solidified.
===George S. Hammond=== {{main|George Hammond (Stargate)}} George S. Hammond is a [[USAF]] Major General (later Lieutenant General) who commands [[Stargate Command]] in the first seven seasons.

Hammond took over from [[Major General West]], commander of the Stargate Project in the original ''[[Stargate (film)|Stargate]]'' film, and originally intended the Stargate Program to be his last assignment before retirement.<ref name="Children of the Gods" /> In season 2's "[[1969 (Stargate SG-1)|1969]]", General Hammond is shown to have worked at the Cheyenne Mountain complex (the present-day location of Stargate Command) in 1969. Hammond originates from [[Texas]]<ref>Master [[Bra'tac]] has been known to call Hammond "Hammond of [[Texas]]"</ref> and became a widower when his wife died of [[cancer]].

He is promoted to the rank of [[lieutenant general]] at the beginning of season 8, being placed in command of the new Homeworld Security command, a department in control of Stargate Command, the ''[[Prometheus (Stargate)|Prometheus]]'' project, and the Atlantian Antarctica outpost. Hammond recurs in the season 1 of ''[[Stargate Atlantis]]'' and seasons 8 through 10 of ''Stargate SG-1''. Hammond appears in a civilian suit instead of a military uniform in season 9's "[[The Fourth Horseman (Stargate SG-1)|The Fourth Horseman]]", and Carter confirms his retired status in season 10's "[[The Road Not Taken (Stargate SG-1)|The Road Not Taken]]". In his last appearance in the alternate timeline film ''[[Stargate: Continuum]]'', Hammond acts as a military advisor to President [[Henry Hayes (Stargate)|Henry Hayes]].

General Landry is introduced in ''SG-1''{{'s}} season 9 premiere, "[[Avalon (Stargate SG-1)|Avalon]]", having been hand-picked by Jack O'Neill to succeed him. Landry once served as a pilot in the [[Vietnam War]]<ref>{{cite episode | title = Uninvited | episode-link = Uninvited (Stargate SG-1) | series = Stargate SG-1 | series-link=Stargate SG-1 | credits = [[Will Waring]] (director); [[Damian Kindler]] (writer) | network = [[Syfy|Sci-Fi Channel]] | season = 10 | number = 5}} * Landry: "I was flying air support out of [[Bien Hoa]].

Bridges said that "Landry truly loves his work [but] respects and appreciates his daughter. He wants a real relationship with her and hopes that will happen some day. At the start of [season 9], you're not sure what their relationship is."<ref name=tvzones64_50 /> The late season 10 episode "[[Stargate SG-1 season 10#ep18|Family Ties]]" brings some conclusion to the Landry-Lam enstrangement, showing a reunification between Landry, Carolyn and Kim Lam in a restaurant.
''[[TV Zone]]''<nowiki>'s</nowiki> Steven Eramo described Landry as "fair, intelligent, even-tempered and having a good sense of humour".<ref name=tvzones74_44>{{cite journal |last=Eramo |first=Steven |title=Actor Beau Bridges – Building Bridges |journal=[[TV Zone]] |issue=Special 74 |pages=44–46 |date=January 2007}}</ref> Bridges thought that "[Landry] likes to empower his team. He realizes how challenged they are. It's a huge burden to protect their country from the entire galaxy, but he also recognizes that, like himself, they are human beings.

And he likes to fool with people."<ref name=gw_bridging_seasons /> According to Bridges, Landry appreciates Carter's knowledge, and needed some patience with the fast-speaking Daniel Jackson to realize "how important a piece of puzzle" he is. He respects Teal'c as a warrior, and is willing to foster the potential he sees in Vala.<ref name=tvzones74_44 />

===Vala Mal Doran=== {{main|Vala Mal Doran}} Vala Mal Doran is a con artist from an unnamed planet and a former human host to the Goa'uld Qetesh. She is played by former ''[[Farscape]]'' actress [[Claudia Black]] in a regular role in season 10 after having recurred in seasons 8 and 9 of ''SG-1''. Her 1st appearance in season 8's "[[Prometheus Unbound (Stargate SG-1)|Prometheus Unbound]]" is followed by a recurring role in season 9, where she and Daniel unintentionally set off the new [[Ori (Stargate)|Ori]] threat. She joins SG-1 after giving birth to the new leader of the Ori at the beginning of season 10, and appears in both direct-to-DVD films.
Vala was created by [[Damian Kindler]] and [[Robert C. Cooper]] as a one-time character, but because of the on-screen chemistry between Black's Vala and Shanks' character Daniel Jackson, and the character's popularity with the producers and the audience, Claudia Black became a recurring guest star in season 9 and joined the main cast in season 10. For her portrayal of Vala, Claudia Black was nominated for a 2006 [[Saturn Award]] in the category "Best Supporting Actress on Television",<ref name="Fetter"/> and won a Constellation Award in the category "Best Female Performer in a 2006 Science Fiction Television" in 2007.<ref>{{cite web |url=http://constellations.tcon.ca/2007.shtml |title=Looking Back At...

It is the main setting in ''Stargate SG-1'' and occasionally features on ''[[Stargate Atlantis]]''. The base extends many levels beneath the ground and is protected from most forms of attack including indirect nuclear detonations, also serving to contain biological, chemical or alien hazards to the outside world by means of a 'lockdown' status. Stargate Command is typically commanded by a General and is staffed by subject matter experts and military support personnel, several elite special operations teams, and several SG teams, including [[SG-1]]. The majority of the teams are [[United States Air Force]] with some [[United States Marine Corps]], civilians and [[United States Army]], but other nations have SG teams operating from the SGC as well after the events of season 5.

On many occasions, she also cares for the health of alien refugees to Earth, including Goa'uld symbiotes. In her first appearance in "[[The Broca Divide (Stargate SG-1)|The Broca Divide]]", Dr. Fraiser holds the rank of captain, and is promoted to major in Season 3. In season 1's "[[Singularity (Stargate SG-1)|Singularity]]", Fraiser adopts [[Cassandra (Stargate)|Cassandra]], an alien orphan whose people had been exterminated by the Goa'uld [[System Lord]] [[Nirrti (Stargate)|Nirrti]]. Dr. Fraiser is killed by a staffweapon blast in season 7's "[[Heroes (Stargate SG-1)|Heroes]]" during an off-world medical emergency, but she returns in season 9's "[[Ripple Effect (Stargate SG-1)|Ripple Effect]]" as a [[Parallel universe (fiction)|parallel universe]] version of Dr. Fraiser, in her reality a regular member of SG-1. Before Fraiser returns to her reality, Carter, Jackson and Teal'c are able to give her a final goodbye. Dr. Fraiser is also shown alive in an alternate timeline in the year 2010 in season 4's "[[2010 (Stargate SG-1)|2010]]", but Fraiser and SG-1 alter the timeline to prevent a catastrophe on Earth involving the [[Aschen (Stargate)|Aschen]] race.
Fraiser joined the [[United States Air Force]] (USAF) after breaking up with her husband; there she got some training with [[firearm]]s. Her husband did not want Fraiser to join the [[US military]] which is one of the main reasons for their [[breakup]]. As a [[Physician|doctor]], Fraiser looks for peaceful solutions and is disinclined towards [[armed force|armed solutions]]. In the episode "[[Serpent's Song (Stargate SG-1)|Serpent's Song]]", Fraiser is the only one in [[Stargate Command]] (SGC) who is resistant to the idea to give [[Apophis (Stargate)|Apophis]] over to his enemies.

[[Teryl Rothery]] was asked by then producer and writer (for ''Stargate'') [[Jonathan Glassner]] and [[Brad Wright]] if she wanted to play the role as Fraiser.<ref name="eclipse"/> In an interview, Rothery was asked what it was like to play a [[Physician|doctor]] in ''[[Stargate SG-1]]''. Rothery replied, "just being true to the character. And as far as the medical stuff, knowing what to do and what to say." She got a lot of help from the medical advisor on the set.
In the first two seasons, Rothery did not have a contract and was booked on every episode in which she appeared. In [[Stargate SG-1 season 3|season three]] of ''SG-1'', she finally got a contract deal with the producers.

=== Walter Davis Harriman === {{anchor|Walter Davis Harriman|Norman|Chevron Guy}} [[Image:Gary Jones stargate cropped.jpg|thumb|Gary Jones played Walter Harriman, an SGC technician who was also known as "Norman Davies" and "Chevron Guy"]] [[Chief Master Sergeant]] Norman Walter Davis Harriman (portrayed by [[Gary Jones (actor)|Gary Jones]], seasons 1–10) joined the [[Stargate Command]] (SGC) after excelling in navigation and automatic flight control operations during the first [[Operation Desert Storm|Gulf War]]. General Hammond recruited him as someone with excellent technical ability and a cool head to operate the Stargate under extreme pressure. He specializes in installing, maintaining and repairing bomb navigation, weapons control as well as automatic flight control systems. He is also an expert in radio and navigational equipment, and in maintaining test and precision measurement equipment. He is primarily a Stargate technician, running the dialing computer and other equipment from the Control Room. He also acts as an occasional administrative assistant to the head of [[Stargate Command]], and has manned the flight console on the bridge of the [[Prometheus (Stargate)|Prometheus]].<ref name="walter"/> From [[Stargate SG-1 season 8|season 8]] to [[Stargate SG-1 season 10|10]], Harriman's role is expanded to advisor to the Head of Command of the SGC.
His name has been a source of confusion for many fans of ''[[Stargate SG-1]]''. Originally, he was simply "[[Technician]]" or "[[Sergeant#United States|Sergeant]]", listed as such in the show credits.<ref name="chevron">{{cite web|author=Gilles Nuytens |url=http://www.thescifiworld.net/interviews/gary_jones_01.htm |title=Interview with Gary Jones |publisher=The SciFi World | access-date=June 17, 2009}}</ref> At some point, some of the writers gave him the name "Norman Davis", which came with a name tag, but was never used in dialogue. In the episode "2010", [[Jack O'Neill]] refers to him as "Walter". Later, in the eighth season of "Stargate SG-1", the character is addressed as "Sergeant Harriman", with "Harriman" actually based on [[General (United States)|General]] [[George Hammond (Stargate)|George Hammond]] addressing him as "Airman" what was misheard by fans because of [[Don S. Davis]]'s Texan accent, resulting in the final name of "Walter Harriman".

As the series continued Harriman got a heavier role in the series. According to Jones, his role was expanded since [[Richard Dean Anderson]] wanted him as his personal assistant in the show when his character [[Jack O'Neill]] was the leader of the SGC.

=== Charles Kawalsky === {{anchor|Charles Kawalsky}} [[File:Jay Acovone Creation Con 2007.jpg|thumb|upright|[[Jay Acovone]] at [[San Diego Comic-Con International|Comic Con]], 2007]]
Charles Kawalsky portrayed by [[John Diehl]] (in the film) and [[Jay Acovone]] (in the series), is introduced in the 1994 ''[[Stargate (film)|Stargate]]'' as [[Lieutenant colonel (United States)|lieutenant colonel]]. He is [[Jack O'Neill]]'s [[second in command]] for the first mission through the [[Stargate (device)|Stargate]] to [[Abydos (Stargate)|Abydos]] and returns to Earth afterwards. When the [[Goa'uld]] [[Apophis (Stargate)|Apophis]] attacks the SGC in [[Children of the Gods|the pilot episode of ''Stargate SG-1'']], Kawalsky is re-introduced as a [[Captain (United States O-3)|captain]] and reunites with his former teammates to bring Daniel Jackson back to Earth. Kawalsky is promoted to [[Major (United States)|major]] and becomes the leader of the newly formed SG-2 team, accompanying SG-1 on their mission to Chulak to rescue [[Sha're]] and [[Skaara]]. However, before returning to Earth, Kawalsky is invaded by a Goa'uld parasite from a dead Jaffa warrior. In season 1's "[[The Enemy Within (Stargate SG-1)|The Enemy Within]]", the [[symbiosis|symbiote]] starts to take control of him back on Earth. A surgical removal of the Goa'uld is initially successful, but the symbiote turns out to be a dead husk whose intelligence has already taken over Kawalsky's mind. Kawalsky is eventually killed when Teal'c forces his head through the [[Stargate (device)#Matter transmission|event horizon]] and closes the gate, severing most of Kawalsky's skull including the lobes controlled by the symbiote.
Despite the character's death, Kawalsky appears several more times in the series. In season 2's "[[The Gamekeeper (Stargate SG-1)|The Gamekeeper]]", O'Neill and Teal'c encounter Kawalsky in a [[virtual reality]] simulation. In season 3's "[[Point of View (Stargate SG-1)|Point of View]]", Kawalsky and [[Samantha Carter]] from an [[Parallel universe (fiction)|alternate reality]] arrive through the gate seeking help in contacting the [[Asgard (Stargate)|Asgard]]. His last appearance is in season 8's "[[Moebius (Stargate SG-1)|Moebius]]", in which Kawalsky returns in an [[alternate history (fiction)|alternate timeline]] accidentally created when the destruction of their time machine traps SG-1 in the distant past. Kawalsky accompanies O'Neill, Carter and Daniel to Chulak and again meets his end, although here he is merely shot; it is the alternate Daniel Jackson who is infected with the Goa'uld and killed by Teal'c.
Darren Sumner called Kawalsky "one of the [1994] film's strongest characters". Sumner called the high death numbers of secondary and recurring characters on the show, ''The Kawalsky Effect''.<ref name="thekawalskyeffect">{{cite web |author=Darren Sumner |url=http://www.gateworld.net/opinion/columns/gatewatch/the_kawalsky_effect.shtml |title=The Kawalsky Effect |publisher=GateWorld |access-date=June 15, 2009 |archive-url=https://web.archive.org/web/20090625133704/http://www.gateworld.net/opinion/columns/gatewatch/the_kawalsky_effect.shtml |archive-date=June 25, 2009 |url-status=dead }}</ref> He also has a card in the [[card game]], ''[[Stargate TCG]]''.

== Recurring NID characters == {{anchor|NID|Trust|International Oversight Advisory|IOA}}
=== Background of NID, Rogue NID, Trust and IOA === The NID is a shadowy [[intelligence agency]] that appears throughout the run of ''[[Stargate SG-1]]'' and occasionally on ''[[Stargate Atlantis]]''. The official mandate of the NID is to provide vital civilian oversight of top secret military operations, but one of their unofficial primary goals is to procure alien technologies. A set of well-resourced illegal cells named the Rogue NID uses unscrupulous methods to achieve the goals of the official NID and is later replaced by The Trust, a shady interplanetary terrorist group. The International Oversight Advisory (IOA) is a civilian oversight committee created after the United States and Russia revealed the existence of the Stargate Program to the other permanent members of the UN Security Council in season 6.{{citation needed|date=April 2023}}

After collaborating with SG-1 in season 7's "[[Heroes (Stargate SG-1)|Heroes, Part 2]]" and "[[Resurrection (Stargate SG-1)|Resurrection]]", Barrett expresses a personal romantic interest in Samantha Carter in season 9's "[[Ex Deus Machina (Stargate SG-1)|Ex Deus Machina]]" and season 10's "[[Uninvited (Stargate SG-1)|Uninvited]]", but she rejects his advances. His last ''SG-1'' appearance is in season 10's "[[Dominion (Stargate SG-1)|Dominion]]". Agent Barrett also recurs in ''[[Stargate Atlantis]]''. He warns General Landry in that show's season 2 episode "[[Critical Mass (Stargate Atlantis)|Critical Mass]]" of the [[Trust (Stargate)|Trust]]'s plan to destroy [[Atlantis (Stargate)|Atlantis]] with a bomb, and aids several Expedition team members to track down [[Rodney McKay]]'s sister [[Jeannie Miller]] on Earth in season 4's "[[Miller's Crossing (Stargate Atlantis)|Miller's Crossing]]".{{citation needed|date=April 2023}}
Peter Flemming had a two-line audition for "Wormhole X-Treme" for a "[[Men in black|Man in Black]]" character in a possible recurring role.

In season 2's "[[Bane (Stargate SG-1)|Bane]]", Maybourne leads an NID attempt to claim Teal'c for study after an alien insect infected Teal'c. After further antagonizing SG-1 through rogue NID operations in "[[Touchstone (Stargate SG-1)|Touchstone]]" and "[[Shades of Grey (Stargate SG-1)|Shades of Grey]]", and helping SG-1 in "[[Foothold (Stargate SG-1)|Foothold]]", Maybourne flees to Russia and aids in establishing the Russian Stargate Program. He is caught in season 4's "[[Watergate (Stargate SG-1)|Watergate]]", convicted of treason, and placed on [[death row]]. O'Neill contacts Maybourne in season 4's "[[Chain Reaction (Stargate SG-1)|Chain Reaction]]" to help reinstate General Hammond, who was blackmailed into resigning from his position. Maybourne escapes after the mission's success and covertly helps O'Neill in season 5's "[[Desperate Measures (Stargate SG-1)|Desperate Measures]]" and "[[48 Hours (Stargate SG-1)|48 Hours]]" in the Adrian Conrad case. Maybourne tricks SG-1 into taking him off-world in season 6's "[[Paradise Lost (Stargate SG-1)|Paradise Lost]]", and is eventually exiled to a far-off planet. When SG-1 meets him again in season 8's "[[It's Good To Be King (Stargate SG-1)|It's Good To Be King]]", Maybourne leads a life of leisure as the seemingly clairvoyant ruler of the local peoples, King Arkhan I. Although the people later discover the deception, they welcome him to stay as his technological expertise has improved their standard of life, and SG-1 returns to Earth without him. He had ascended to power using an Ancient time-travelers log of his journeys into the future of the planet and ended up facing a Goa'uld invasion, but the soldiers were repelled by Jackson and Teal'c with help from one of the villagers, and O'Neill destroyed in the ship in orbit, killing the System Lord behind the attack. When the team leave, O'Neill and Maybourne part amicably with Maybourne having finally accepted responsibility towards the people he was ruling.{{citation needed|date=April 2023}}
After auditioning for the part as Harry Maybourne, the producers revealed that he "maybe" could get a spot as a recurring character in the show.

=== Robert Kinsey === [[Image:Ronnycox.jpg|thumb|Ronny Cox plays Robert Kinsey.]] {{anchor|Robert Kinsey}} [[United States Senate|Senator]] Robert Kinsey, (played by [[Ronny Cox]], seasons 1, 4–8) – A US senator who first appears in season 1's "[[Politics (Stargate SG-1)|Politics]]". In "Politics", Kinsey ignores warnings of an imminent Goa'uld invasion and instead manages to briefly shut down Stargate Command for budget reasons, only for SG-1 to prove the program's worth and save Earth through defying orders. In season 4's "[[Chain Reaction (Stargate SG-1)|Chain Reaction]]", Kinsey and the NID temporarily succeed in controlling the Stargate by blackmailing General Hammond into retirement and appointing a new general to his position, but O'Neill is able to find evidence of the blackmail and get Hammond reinstated. In season 5's "[[2001 (Stargate SG-1)|2001]]", Kinsey aims to gain prestige through an alliance with the [[Aschen (Stargate)|Aschen]], but the alliance fails (However, the alliance went ahead in the alternate but unfulfilled future reality witnessed in season 4's "[[2010 (Stargate SG-1)|2010]]", in which Kinsey also achieved his goal of the presidency; only a warning from that future helped the SGC prevent it). In season 6's "[[Smoke and Mirrors (Stargate SG-1)|Smoke and Mirrors]]", a group controlling the rogue NID, known as "the Committee", tries to assassinate Kinsey and frame Col. O'Neill for his murder, but NID agent Malcolm Barret and SG-1 foil this attempt. Kinsey becomes [[Vice President of the United States|Vice-president]] in season 7's "[[Inauguration (Stargate SG-1)|Inauguration]]" and tries again to take control of the Stargate Program in "[[Lost City (Stargate SG-1)|Lost City]]". Shortly after NID Agent [[Richard Woolsey]] presents incriminating evidence against Kinsey to President [[Henry Hayes (Stargate)|Henry Hayes]] in the same episode, Hayes "accepts" Kinsey's resignation. Kinsey makes his last appearance in season 8's "[[Stargate SG-1 season 8|Full Alert]]", where the SGC convinces Kinsey to go undercover to undermine the hierarchy of the Trust. However, the Goa'uld have completely infiltrated the Trust through their operatives working outside of the solar system, and have already implanted a symbiote within Kinsey to aid in their plans of starting a nuclear war between the US and Russia. After the SGC foil the attempt, Kinsey flees aboard an Al'kesh, but Kinsey's future remains uncertain as the Al'Kesh is destroyed while he operated a transport device, leaving it open-ended if he was able to escape or the ship was destroyed before he could transport away. Kinsey is briefly mentioned as a President in the alternative timeline (with Hayes as Secretary of Defense) in season 8 finale "[[Moebius (Stargate SG-1)|Moebius]]".{{citation needed|date=April 2023}}
The producers of ''[[Stargate SG-1]]'' asked [[Ronny Cox]] if he would be interested in a role in one episode, but according to Cox it was "so much fun that they and I decided we would like to do more together". According to [[executive producer]] [[Brad Wright]], every time they got a [[Teleplay|script]] from an outside editor, Kinsey was included. Cox has been noted for saying that the character has become a "Malevolent force on the show". Because of the collaboration between the producers and himself, Cox described him as a "self-aggrandizing senator who like[s] to throw his weight around", and as "Kinsey feels that the [[Stargate (device)|Stargate]] [is] being used in completely the wrong way and one that is endangering American ideals and a way of life that he believes in" and a "Born-again, right-wing, Christian fundamentalist"; Cox played him as a heroic antagonist rather than villainous.

[[Robert Picardo]] was in the main cast of ''[[Star Trek: Voyager]]'' from 1995 to 2001. He was familiar with ''Stargate SG-1'' from his time as a [[Showtime (TV network)|Showtime]] subscriber. He was offered a one-day guest star as Richard Woolsey for the ''SG-1'' episode "[[Heroes (Stargate SG-1)|Heroes]]" in season seven (2004) while he was working on ''[[The Outer Limits (1995 TV series)|The Outer Limits]]'' in [[Vancouver]] (where ''Stargate SG-1'' is filmed). He was then brought back for the follow-up episode "[[Inauguration (Stargate SG-1)|Inauguration]]", which began the rehabilitation of the Woolsey character. With the story introduction of the [[IOA (Stargate)|IOA]], the Woolsey character made more regular appearances to "annoy people". Eventually, humor was added to the role, and the character was spun over to ''Atlantis'' as a recurring guest character. Picardo later became a [[main character]] in ''[[Stargate Atlantis]]''.<ref name="bravenewwoosley">{{cite web|first=Darren|last=Sumner|url=https://gateworld.net/news/2008/07/brave-new-woolsey/|title=Brave New Woosley|publisher=[[GateWorld]]|date=2008-07-15|access-date=2009-04-06}}{{Dead link|date=May 2026 |bot=InternetArchiveBot }}</ref><ref name=jm_080926>{{cite web|first=Joseph|last=Mallozzi|url=http://josephmallozzi.wordpress.com/2008/09/26/september-26-2008-robert-picardo-answers-your-questions/|title=2008-09-26 Robert Picardo Answers Your Questions|publisher=josephmallozzi.wordpress.com|date=2008-09-28 |access-date=2009-06-18}}</ref>

=== Earth ship crew characters=== {{anchor|Earth ships|X-301|X-302|F-302|Prometheus|Daedalus|Odyssey|Korolev|Apollo|Sun Tzu}} In the show, Earth's efforts to construct starships of its own using reverse-engineered alien technology begin in the season 4 episode "[[Tangent (Stargate SG-1)|Tangent]]", with the less-than-successful X-301. The first spaceworthy Earth fighter, the X-302 (later F-302), is introduced in season 6's "[[Redemption (Stargate SG-1)|Redemption]]", and a few episodes later in "[[Prometheus (Stargate SG-1)|Prometheus]]", Earth's first space battlecruiser, the ''[[Prometheus (Stargate)|Prometheus]]''. Squadrons of F-302s are eventually stationed on Earth, [[Atlantis (Stargate)|Atlantis]], the SGC's alternative sites, and its battlecruisers. In season 2 of ''Stargate Atlantis'', the ''Daedalus''-class battlecruiser is introduced, incorporating advancements that were tested on the ''Prometheus''. Six ''Daedalus''-class battlecruisers appeared in the franchise: the ''Daedalus'', the ''Odyssey'', the ''Korolev'', the ''Apollo'', the ''Sun Tzu'', and the ''George Hammond'' (named the ''Phoenix'' in an alternate timeline). Except for the ''Korolev'' and the ''Sun Tzu'', which are operated by the Russians and Chinese respectively, all Earth combat spacecraft are operated by the [[United States Air Force]].
Set designer Peter Bodnarus based the design of the F-302 on the [[F-117A]] U.S. Air Force stealth fighter and the [[Northrop HL-10|HL-10]] aircraft from the 1970s, while still leaving the Goa'uld glider origins of the design recognizable. He and his team focused on creating a realistic-looking cockpit interior for the X-302 in terms of the headrest with overhead ejection handles and emergency systems.<ref name=tvzones46_41>{{Cite journal |last=Eramo |first=Steven | title=SG-1 – The Production Design Team – Peter Bodnarus – Set Designer |newspaper=[[TV Zone]] |issue=Special 46 |pages=41–42 |date=July 2002 }}</ref> The original concepts for the look of the ''Prometheus'' as well as the X-303's interior were [[aircraft carrier]]s.<ref name=tvzones46_41 /><ref name=ac_914 /> For the ''Prometheus'', the producers wanted to build something that was exactly the opposite of Goa'uld ships, which, according to [[Paul Mullie]], are basically big empty rooms with nowhere to sit, no screens and no buttons to press.

==Abydonians==
The Abydonians are the people whom Colonel O'Neill's team encounters on another planet in the [[Stargate (film)|''Stargate'' film]]. They are the slaves of the alien [[Ra (Stargate)|Ra]] and are descendants from [[ancient Egypt]]ians brought through the Stargate to mine the fictional mineral naqahdah. The film gives the location of their homeworld—named Abydos in ''SG-1''<nowiki>'s</nowiki> pilot episode "[[Children of the Gods]]"—as the Kaliem galaxy "on the far side of the known universe" in the film; and as the closest planets to Earth in the Stargate network in "Children of the Gods". In the film, O'Neill and Daniel Jackson inspire the Abydonians and their leader, Kasuf, to rise up against Ra. The military personnel return to Earth, while Daniel falls in love with Kasuf's daughter Sha're and remains behind. In "Children of the Gods", set a year after the film, the Goa'uld [[Apophis (Stargate)|Apophis]] attacks Abydos, abducting Sha're and her brother Skaara to serve as hosts for his queen Amonet and son Klorel. In season 6's "[[Full Circle (Stargate SG-1)|Full Circle]]", the Goa'uld [[Anubis (Stargate)|Anubis]] destroys Abydos, but [[Oma Desala]] helps its entire population [[Ascension (Stargate)|Ascend]].

Kasuf helps Daniel to hide the newborn child from [[Heru-ur (Stargate)|Heru-ur]]. Kasuf returns in season 3's "[[Forever in a Day (Stargate SG-1)|Forever in a Day]]" when his daughter Sha're dies. Kasuf last appears in season 4's "[[Absolute Power (Stargate SG-1)|Absolute Power]]", introducing SG-1 to his rapidly aged grandchild, Shifu. In the prequel web series ''Origins'', it is shown that Kasuf served Aset in Abydos and met Catherine Langford and her group when a German officer named Brucke first activated the Stargate in a warehouse near Giza on Earth. Upon Ra's return to Abydos, Aset made Kasuf the leader of the village of Nagada. * {{Anchor|Sha're|Shau'ri|Amaunet|Amonet}} Sha're (Sha'uri in the film), played by [[Mili Avital]] (film) and [[Vaitiare Bandera]] (seasons 1–3) – Kasuf's daughter who becomes Daniel Jackson's wife and the host of the Goa'uld Amonet (also spelled Amaunet). In the film, her father Kasuf offers Sha're to Daniel Jackson as a gift, and although he initially refuses to take her as his wife, they eventually fall in love with each other. After one year of marriage in "Children of the Gods", [[Apophis (Stargate)|Apophis]] takes Sha're hostage and makes her a host for his symbiote queen Amonet against her will. Daniel meets a now vastly-pregnant Sha're on a visit to Abydos in season 2's "[[Secrets (Stargate SG-1)|Secrets]]". She hides her child, a [[Harcesis]] fathered by Apophis, from [[Heru-ur (Stargate)|Heru-ur]] as Amonet is dormant during the pregnancy.

Skaara wins the trial and eventually returns to Abydos, where he meets SG-1 one last time in the season 6 finale, "[[Full Circle (Stargate SG-1)|Full Circle]]". Skaara helps SG-1 in the search for the [[Eye of Ra]] before [[Anubis (Stargate)|Anubis]] can find it on Abydos. Skaara is mortally wounded during the firefight with Anubis' Jaffa, but ascends with the help of [[Oma Desala]].
==Ancients== {{main|Ancient (Stargate)}} {{see also|List of Stargate Atlantis characters#Ancients}} The Ancients are the original builders of the [[Stargate (device)|Stargate]] network, who, by the time of ''Stargate SG-1'', have [[Ascension (Stargate)|ascended]] beyond corporeal form to a higher plane of existence. The humans of Earth are the "second evolution" of the Ancients. The Ancients (originally known as the [[Alterans]]) colonized the Milky Way galaxy millions of years ago and built a great empire. They also colonized the Pegasus galaxy and seeded human life there before being driven out by the [[Wraith (Stargate)|Wraith]]. The civilization of the Ancients in the Milky Way was decimated millions of years ago by a plague and those who did not learn to ascend travelled to the Pegasus galaxy on board [[Atlantis (Stargate)|Atlantis]]. With few exceptions, the ascended Ancients respect free will and refuse to interfere in the affairs of the material galaxy. However, their legacy is felt profoundly throughout the ''Stargate'' universe, from their technologies such as Stargates and Atlantis to the Ancient Technology Activation gene that they introduced into the human genome through interbreeding.
===Oma Desala===
Oma Desala ("Mother Nature"), played by Carla Boudreau (season 3) and [[Mel Harris]] (seasons 5, 8) – An Ascended being who goes against the ways of the Ancients. It is unclear if she is an Ancient herself, as the Ancients Orlin and Merlin give different accounts of knowing Oma. Oma is responsible for once helping the fallen System Lord [[Anubis (Stargate)|Anubis]], the main ''SG-1'' antagonist between seasons 5 through 8, ascend. Although the Ancients banished her for her actions, Oma remains convinced of her responsibility to guide those beneath to the "Great Path" of enlightenment, even if this interferes in the lower planes of existence. Oma therefore only guides individuals, leaving the final decision to travel the great path to them. SG-1 first encounters Oma Desala on their search for Shifu in season 3's "[[Maternal Instinct (Stargate SG-1)|Maternal Instinct]]". Oma eventually guides Shifu to ascension in season 4's "[[Absolute Power (Stargate SG-1)|Absolute Power]]". Oma is involved in Daniel Jackson's ascension in "[[Meridian (Stargate SG-1)|Meridian]]" and forceful de-ascension in "[[Fallen (Stargate SG-1)|Fallen]]", and also helps the entire [[Abydonians (Stargate)|Abydonian]] population ascend after [[Anubis (Stargate)|Anubis]]'s attack in season 6's "[[Full Circle (Stargate SG-1)|Full Circle]]". Oma Desala last appears in season 8's "[[Threads (Stargate SG-1)|Threads]]", sacrificing herself to enter an eternal battle with Anubis to prevent him from wreaking further havoc on the galaxy.
Note: Mel Harris's teenage son was a ''Stargate SG-1'' fan and introduced her to the series. The ''Stargate'' producers offered her the part when she was visiting the set while in Vancouver for another job. The best direction she got for playing this almost "omniscient" character was that she was not like others and was a "being" of her own.<ref>{{cite web|last=Read|first=David|url=https://gateworld.net/news/2004/06/oma-in-brief/|title=Oma In Brief: An interview with Mel Harris|publisher=[[GateWorld]]|date=June 14, 2004|access-date=2008-11-27}}{{Dead link|date=May 2026 |bot=InternetArchiveBot }}</ref>
==Asgard== {{anchor|Asgard|Aegir|Heimdall|Loki}}
The Asgard are a benevolent race whose former homeworld is the planet [[Othala]]. According to the mythology of ''Stargate'', they gave rise to [[Norse mythology]] on Earth and inspired accounts of the [[Roswell, New Mexico|Roswell]] [[grey alien]]s. The Asgard can no longer reproduce and perpetuate themselves by transferring their minds into new clone bodies as necessary. Extremely advanced technologically, the threat of their intervention shields many planets in the Milky Way from [[Goa'uld]] attack, including Earth.
The Asgard provide much assistance to Earth in the way of technology, equipment, and expertise. Their main adversaries in ''Stargate SG-1'' are the mechanical [[Replicator (Stargate)|Replicators]], against which they enlist the aid of SG-1 on several occasions. The entire Asgard civilization chooses to self-destruct in "[[Unending]]" (S10E20; series finale) due to the degenerative effects of repeated cloning. A small colony of Asgard still exists in the Pegasus galaxy and they were able to stop cloning's diminishing returns.
Most Asgard characters on the show are directly named after [[Norse mythology|Norse gods]]. Prominent one-time characters include Aegir (voiced by [[Michael Shanks]] in "[[New Order (Stargate SG-1)|New Order]]", named after [[Aegir]]), Heimdall (voiced by [[Teryl Rothery]] in "[[Revelations (Stargate SG-1)|Revelations]]", named after [[Heimdallr]]) and Loki (voiced by [[Peter DeLuise]] in "[[Fragile Balance (Stargate SG-1)|Fragile Balance]]", named after and based on [[Loki]]). ''Stargate SG-1'' had several Asgard puppets, and six puppeteers were necessary to make the different parts of the main Asgard puppet work.<ref>{{cite video|people=[[Andy Mikita|Mikita, Andy]]|date=2005|title=Audio commentary for "[[New Order (Stargate SG-1)|New Order]]"|medium=DVD|publisher=[[MGM]]}}</ref>
===Thor=== {{anchor|Thor}}
Thor, voiced by [[Michael Shanks]] (seasons 1–8, 10) – The Supreme Commander of the Asgard Fleet. [[SG-1]] first encounter him as a [[Viking]] holographic recording (played by [[Mark Gibbon]]) on the planet [[Cimmeria (Stargate)|Cimmeria]] in "[[Thor's Hammer (Stargate SG-1)|Thor's Hammer]]". They meet the real Thor one season later when they enlist him to save Cimmeria from [[Heru-ur (Stargate)|Heru-ur]]'s invasion. After O'Neill manages to make friendly contact with the Asgard in their galaxy, Thor includes Earth in the [[Protected Planets Treaty]] to safeguard it from a direct Goa'uld attack. Late in season 3, SG-1 helps to destroy Thor's ship, the ''Beliskner'', which had been overtaken by the [[Replicator (Stargate)|Replicators]], in "[[Nemesis (Stargate SG-1)|Nemesis]]". Impressed by SG-1's primitive but effective tactics, Thor requests SG-1 to help fight the Replicators in his Asgard homeworld soon after, in "[[Small Victories]]" Anubis captures Thor and probes his mind for Asgard technology, and Thor's body lapses into a coma in "[[Revelations (Stargate SG-1)|Revelations]]". SG-1 retrieve Thor's consciousness from the ship's database a while later, and transfer it into a new body.
Thor asks for SG-1's assistance after his people's plan to trap the Replicators inside a time-dilation field on the planet Halla backfired. Thor personally makes an appearance at a secret meeting between the permanent members of Earth's [[UN Security Council]] taking place in [[the Pentagon]], to ensure that [[Stargate Command|SGC]] retains control over the Earth [[Stargate (device)|Stargate]]. As the time-dilation device on Halla cannot keep the Replicators bottled up forever, Thor collapses Halla's sun into a [[black hole]], but some Replicators escape. Some weeks later, Thor and Carter modify their Replicator Disruptor, but as the Replicators quickly adapt, they use the [[Mythology of Stargate#Dakara|Dakara]] superweapon to destroy all Replicators in one strike. Thor gets a new clone body soon after. Thor summons the ''Odyssey'' to the Asgard homeworld Orilla and installs the entire knowledge base of the Asgard race on the ship. As attempts to save the Asgard civilization from their genetic difficulties have failed, he informs Lt. Col. Carter that the Asgard consider people of Earth the fifth race, heirs first to the Ancients and now the Asgard, and that it is their turn to safeguard the future. Thor perishes along with the rest of the Asgard race when their planet [[self-destruct]]s before the [[Ori (Stargate)|Ori]] can attack. Carter later programs the Asgard data core's interface to look and behave like Thor, but admits that it is not the same as talking to the god that became her friend.
Thor originally speaks more slowly in the first season, but Michael Shanks, who voiced him since the beginning, joked that he was not getting paid by the hour but by the amount of dialog, when he commented on the increased dialog speed in later episodes. As the Thor puppet is able neither to walk nor stand, the puppet is often put in a chair.<ref name=ac_401_jt>{{cite video |people=[[James Tichenor]] (VisFX supervisor) |date=2001 |title=Audio Commentary for "Small Victories" |medium = DVD – Stargate SG-1: Season 4 |publisher=[[MGM Home Entertainment]]}}</ref>
==Goa'uld== {{main|Goa'uld}} The Goa'uld are the dominant race in the Milky Way and the primary adversaries from seasons 1 to 8 of ''Stargate SG-1''. The most powerful Goa'uld in the galaxy are collectively known as the System-Lords. They are a parasitic species that resembles finned snakes, which can burrow themselves into a humanoid's neck and wrap around the spinal column. The Goa'uld symbiote then takes control of its host's body and mind, while providing longevity and perfect health. In their fictional backstory, the Goa'uld invaded and ruled over Earth thousands of years ago, masquerading as gods from ancient mythologies. The Goa'uld transplanted humans throughout the galaxy to serve as slaves and hosts, and created the Jaffa to serve as incubators for Goa'uld larvae.
===Anubis===
Anubis, played by [[David Palffy]] (seasons 5–7, hooded), Dean Aylesworth and Rik Kiviaho (season 8's "[[Reckoning (Stargate SG-1)|Reckoning]]"), and [[George Dzundza]] (season 8 as "Jim") – A half-[[Ascension (Stargate)|ascended]] Goa'uld System Lord who replaces [[Apophis (Stargate)|Apophis]] as the main enemy in season 5. Based on the god [[Anubis]] of [[Egyptian mythology]], the character is first mentioned by name in season 5's "[[Summit (Stargate SG-1)|Summit]]" (although is alluded to in the earlier episode "[[Between Two Fires (Stargate SG-1)|Between Two Fires]]"), and makes his first appearance in "[[Revelations (Stargate SG-1)|Revelations]]". It is revealed that like all the other Egyptian "gods", he is in fact a Goa'uld—one so vicious and cruel that he was banished by the other Goa'uld. Earth is eventually able to annihilate Anubis's fleet above Antarctica in "[[Lost City (Stargate SG-1)|Lost City]]", but Anubis survives in energy form ("[[Lockdown (Stargate SG-1)|Lockdown]]"). Anubis regains his power throughout season 8 and develops a plan to destroy all life in the galaxy and then repopulate it to his own designs ("[[Reckoning (Stargate SG-1)|Reckoning]]"). Just as he prepares to use the weapon in "[[Threads (Stargate SG-1)|Threads]]", [[Oma Desala]], who aided in his ascension thousands of years ago, engages him in an eternal battle.
David Palffy was cast to play [[Sokar (Stargate)|Sokar]] before he got the part of Anubis.<ref name="gw_anubis1">{{cite web|last=Read|first=David|url=https://gateworld.net/news/2004/07/the-hour-of-anubis-part-1/|title=The Hour of Anubis (Part 1 of 3) – GateWorld talks with David Palffy|publisher=[[GateWorld]]|date=July 2004|access-date=2008-12-22}}{{Dead link|date=May 2026 |bot=InternetArchiveBot }}</ref> Since Anubis is cloaked all the time, Palffy had to express the character's weight through the voice and movements. Mainly because of the severe time-restraints of filming television, the producers gave Palffy no background on the character and encouraged Palffy to experiment and find the character's tone himself.<ref name="gw_anubis2">{{cite web|last=Read|first=David|url=https://www.gateworld.net/news/2004/07/the-hour-of-anubis-part-2/|title=The Hour of Anubis (Part 2 of 3) – GateWorld talks with David Palffy|publisher=[[GateWorld]]|date=July 2004|access-date=2008-12-22}}{{Dead link|date=May 2026 |bot=InternetArchiveBot }}</ref> What was under Anubis' cloak became a main question among fandom.<ref name=gw_anubis1 /> Anubis was received as an over-the-top-character,<ref name=gw_anubis2 /><ref name=anubis3 /> but Palffy pointed to what the character represents, saying "Anubis is a god – he's not fully ascended, he's basically an outcast. And as I say, this resulting displacement of energy that's evil, that has been temporarily harnessed under a hood to give him physical form. He's the image of death, the figure of death incarnate, and he's surrounded by a black robe. That symbol in itself has been around since the dawn of time. That in itself is over the top. [...] His whole existence is basically predicated on living up to that theme, and that's a theme that's time immemorial. And of course, as an actor, you've got to work with that. To do otherwise, to underplay that, will work against the idea of what he represents."<ref name=anubis3 /> Palffy was open to continue playing Anubis beyond season 7, but other actors played the character in season 8.<ref name="anubis3">{{cite web|last=Read|first=David|url=https://www.gateworld.net/news/2004/07/the-hour-of-anubis-part-3/|title=The Hour of Anubis (Part 3 of 3) – GateWorld talks with David Palffy|publisher=[[GateWorld]]|date=July 2004|access-date=2008-12-22|archive-date=2019-07-20|archive-url=https://web.archive.org/web/20190720013736/https://www.gateworld.net/news/2004/07/the-hour-of-anubis-part-3/|url-status=live}}</ref>
===Apophis=== [[File:Apophis Symbol (Stargate).svg|thumb|100px|Apophis' symbol]] Apophis, played by [[Peter Williams (actor)|Peter Williams]] (seasons 1–6, 8) – A System Lord and the main villain for most of the first four seasons of ''Stargate SG-1''. Based on the god [[Apep]] of [[Egyptian mythology]], the character gained power after [[Ra (Stargate)|Ra]]'s death in the film and commands a raid on Earth and [[Abydos (Stargate)|Abydos]] in "[[Children of the Gods]]", leading to the restart of the Stargate Program. His then First Prime, Teal'c, defects from his army afterwards. Apophis's standing amongst the System Lords is severely diminished after a failed full-scale assault on Earth in season 2's "[[The Serpent's Lair (Stargate SG-1)|The Serpent's Lair]]". Apophis is killed and eventually revived by the Goa'uld [[Sokar (Stargate)|Sokar]] in season 3. After defeating Sokar's massive fleet and army in season 3's "[[The Devil You Know (Stargate SG-1)|The Devil You Know]]", Apophis becomes the most powerful Goa'uld in the galaxy. Despite his death aboard his [[Replicator (Stargate)|Replicator]]-infested ship in season 5's "[[Enemies (Stargate SG-1)|Enemies]]", Apophis appears in visions and alternate timelines in season 6's "[[The Changeling (Stargate SG-1)|The Changeling]]", season 8's "[[Moebius (Stargate SG-1)|Moebius]]" and ''[[Stargate: Continuum]]''. In the latter, he is the last System Lord to resist the rule of Ba'al who kills Apophis shortly before his attempted takeover of Earth.
The astronomers [[David J. Tholen]] and [[Roy A. Tucker]] enjoyed the character so much that they named a [[near-Earth asteroid]] that they co-discovered in 2004, [[99942 Apophis]].<ref>{{cite journal |last=Cooke |first=Bill |url=http://www.astronomy.com/asy/default.aspx?c=a&id=3434 |title=Asteroid Apophis set for a makeover |journal=Astronomy Magazine |date=August 18, 2005 |archive-url=https://web.archive.org/web/20051110131201/http://www.astronomy.com/asy/default.aspx?c=a&id=3434 |archive-date=2005-11-10}}</ref>
===Ba'al=== [[File:Baal Symbol (Stargate).svg|thumb|100px|Ba'al's symbol]] Ba'al, played by [[Cliff Simon]] (seasons 5–10) – A System Lord based on the [[Baal]] of [[Canaanite religion]]. Introduced in season 5's "[[Summit (Stargate SG-1)|Summit]]" and recurring until the end of the show, he is the longest-running villain in ''Stargate'' history. After Anubis' fleet is destroyed in season 7's "[[Lost City (Stargate SG-1)|Lost City]]", Ba'al gains substantial power and wages a war against all other System Lords, driving them to the brink of defeat in early and mid-season 8. Anubis' return in "[[Reckoning (Stargate SG-1)|Reckoning]]"/"[[Threads (Stargate SG-1)|Threads]]" forces Ba'al back into his service. Ba'al secretly collaborates with SG-1 and [[Jacob Carter|Jacob/Selmak]] to thwart Anubis' plan of overtaking the galaxy with the Dakara Superweapon, but flees when the Jaffa storm his mothership. With his traditional power base gone, Ba'al exiles to Earth and takes over the [[Trust (Stargate)|Trust]], posing as a wealthy businessman in season 9's "[[Ex Deus Machina]]". Having made multiple clones of himself, Ba'al begins a campaign to battle the invading [[Ori (Stargate)|Ori]] for control of the galaxy in "[[Stronghold (Stargate SG-1)|Stronghold]]" and tries to gain power through various means in "[[Off the Grid (Stargate SG-1)|Off the Grid]]", and season 10's "[[Insiders (Stargate SG-1)|Insiders]]" and "[[The Quest (Stargate SG-1)|The Quest]]". Ba'al captures [[Adria (Stargate)|Adria]] in "[[Dominion (Stargate SG-1)|Dominion]]" and implants one of his cloned symbiotes within her, massacring most of his other clones with symbiote poison. The symbiote is extracted and killed, but he fatally poisons Adria first, forcing her Ascension to survive. The [[Tok'ra]] extract the symbiote from the last Ba'al clone in ''[[Stargate: Continuum]]''. However, the real Ba'al travels back in time to 1939 and alters history by intercepting the Stargate as it is transported by the ocean freighter ''Achilles'', creating a timeline in which Ba'al gains dominion over the System Lords and lays siege to Earth with Teal'c as his First Prime and Qetesh, the Goa'uld who used Vala as a host, as his queen. Cameron Mitchell manages to travel back in time to 1929 and set an ambush for Ba'al when he boards the ''Achilles''. The real Ba'al is shot and killed by Mitchell, restoring the original timeline. With Ba'al gone, the extraction of the last Ba'al clone proceeds as planned and the symbiote dies, ending the reign of the System Lord forever. Ba'al's host survives the extraction and Vala plans to help him adjust to life after over two thousand years under Ba'al's control.
[[Cliff Simon]] met with [[executive producer]]s [[Robert C. Cooper]] and [[Brad Wright]] and auditioned eight months before the character Ba'al was created for the series. Simon, Cooper and Wright came to an agreement to wait until they found the right character for Simon in the show. Simon said "I was very lucky," when talking about his character in an interview with The Sci Fi World.<ref name="scifi">{{Cite web| author=Gilles Nuytens |url=http://www.thescifiworld.net/interviews/cliff_simon_01.htm |title=Cliff Simon Interview |publisher=The Sci Fi World |access-date=2009-04-16}}</ref> According to portraying actor Simon, Ba'al was the most "interesting" character he had done, because of Ba'al's character development and diversity. Simon felt that he needed to diversify the character to make it more exciting. As he put it, "if you're always bad, it gets pretty boring." He wanted to change the development of the character. The writing staff eventually agreed with him and started fleshing out his character.<ref name="dragon">{{Cite web |author=Desiree Jackson |url=http://dailydragon.dragoncon.org/2008/system-lord-summit-with-cliff-simon/ |title=System Lord Summit: An Interview with Cliff Simon |date=September 2008 |publisher=Daily Dragon |access-date=2009-04-16 |archive-date=2008-10-18 |archive-url=https://web.archive.org/web/20081018224254/http://dailydragon.dragoncon.org/2008/system-lord-summit-with-cliff-simon/ |url-status=live }}</ref>
==Jaffa== {{main|Jaffa (Stargate)|Teal'c}} The Jaffa are an offshoot of humanity, genetically engineered by the [[Goa'uld]]. They have an abdominal pouch which serves to incubate larval Goa'uld. The infant Goa'uld provides strength, longevity, and good health, at the cost of supplanting the Jaffa's natural immune system, making them dependent on the Goa'uld for more symbiotes. The Jaffa have a warrior culture and form the armies of the Goa'uld. In season 8 of ''Stargate SG-1'', the [[Jaffa Resistance]] wins their race's freedom from Goa'uld oppression, resulting in the [[Free Jaffa Nation]].
===Bra'tac=== {{Anchor|Bratac|Bra'tac}} [[File:Tony Amendola Creation Official Stargate Convention 2007.jpg|thumb|[[Tony Amendola]] played Bra'tac from season 1 through 10 of ''Stargate SG-1''.]]
Bra'tac, played by [[Tony Amendola]] (seasons 1–3, 5–10) – A Jaffa warrior, former [[First Prime]] of the [[Goa'uld]] [[System Lord]] [[Apophis (Stargate)|Apophis]], and Teal'c's former teacher and closest friend.<ref>{{Citation |title=002: Tony Amendola, "Bra'tac" in Stargate SG-1 (Interview) | date=10 October 2020 |url=https://www.youtube.com/watch?v=OReoltxqeu0 |access-date=2023-09-01 |language=en}}</ref> His surviving to an age of retirement as First Prime is a noted rarity, and affords him a significant amount of respect among Jaffa.

Bra'tac, having been one of the first Jaffa to doubt the Goa'uld as gods, has been an outcast among the Jaffa since at least season 1. Bra'tac was also the one who initially influenced Teal'c to doubt the Goa'uld as well. Bra'tac helps Teal'c and SG-1 on many missions. He is initially suspicious of the humans, particularly O'Neill. This dynamic is played out somewhat comically, but Bra'tac slowly learns to trust and respect humans.<ref name="tvzones46_10">{{Cite journal | last=Eramo | first=Steven | title=Tony, Tony | journal=[[TV Zone]] | issue=Special #46 | pages=10–11 | date=July 2002 }}</ref> In seasons 1 and 2, Bra'tac helps to save Teal'c's son, [[Rya'c]] from several threats and becomes a guardian to him. During a mission to find the [[Harcesis]] child ([[Shifu (Stargate)|Shifu]]) on Kheb in season 3's "[[Maternal Instinct (Stargate SG-1)|Maternal Instinct]]", Bra'tac is presented with the idea of [[Ascension (Stargate)|Ascension]] but in the end decides against this possibility for himself. At the end of season 6, Bra'tac and Teal'c are both badly wounded during a Jaffa meeting and lose their symbiotes, surviving only by taking the new drug Tretonin. Bra'tac is the primary instigator of the [[Jaffa Resistance]], a rebellion aimed at overthrowing the Goa'uld and establishing the freedom of all Jaffa. At the end of season 8, Bra'tac and Teal'c convince the other members of the Jaffa Rebellion to attack Dakara in an ultimately successful mission. The Jaffa obtain freedom, and Bra'tac receives a position of honor. He becomes a member of the High Council, the governing body of the new [[Free Jaffa Nation]] but still stays loyal to Stargate Command. Some time after the destruction of Dakara by the [[Ori (Stargate)|Ori]], leaders of the Free Jaffa Nation meet to consider the future, but Bra'tac and Teal'c are badly injured during an ambush by a former enemy of Teal'c. When they get nursed back at the SGC, Bra'tac tells Teal'c that he is like a son to him.
==Lucian Alliance== {{redirect|Lucian Alliance|characters in Stargate Universe|List of Stargate Universe characters#Recurring Lucian Alliance characters}} The Lucian Alliance is an interstellar group of human smugglers and mercenaries that have joined together from many different human-settled worlds across the Milky Way Galaxy to fill the power vacuum created by the demise of the [[Goa'uld]], and have obtained and modified Goa'uld technology for their own use. When their trade partner [[Vala Mal Doran]] does not keep an agreement in their first appearance in season 8's "[[Prometheus Unbound (Stargate SG-1)|Prometheus Unbound]]", she and Daniel are placed on a Lucian Alliance wanted list. The Lucian Alliance is first referred to by name in season 9's "[[The Ties That Bind (Stargate SG-1)|The Ties That Bind]]" and reappears as a recurring foe in seasons 9 and 10. The Lucian Alliance story arc is continued in ''[[Stargate Universe]]''. Producer [[Joseph Mallozzi]] explained in retrospect, "Much of the Lucian Alliance we saw in ''SG-1'' was inept and, dare I say it, a bit goofy. They fit in with ''SG-1''{{'}}s lighter, more high adventure-driven tone but would have stood out (and not in a good way) in the new series [''Stargate Universe'']. As a result, I was initially leery at the prospect of introducing them to ''SGU'' but, as so often happened over the course of my many years in the franchise, I trusted in Brad [Wright] and Robert [C. Cooper] and, in the end, that trust was rewarded with a terrific story element that not only succeeded as planned [...] but offered up plenty of interesting story material for future episodes [of ''Stargate Universe'']. The Alliance was always envisioned as a loose coalition of mercenary groups so it made sense that certain factions would have been more capable and threatening than others."<ref>{{cite web |last=Mallozzi |first=Joseph |author-link=Joseph Mallozzi |url=http://josephmallozzi.wordpress.com/2010/12/25/december-25-2010-christmas-marty-g-and-the-return-of-the-mailbag/ |title=December 25, 2010: Christmas!

* {{anchor|Jup|Tenat|Jup and Tenat}} Jup and Tenat, played by Geoff Redknap and Morris Chapdelaine (seasons 8–10) – Oranian minor members of the Lucian Alliance who make their first appearance in season 8's "[[Prometheus Unbound (Stargate SG-1)|Prometheus Unbound]]", aiming to trade a case of weapons-grade-refined naqahdah to Vala in exchange for the stolen ''[[Prometheus (Stargate)|Prometheus]]''. After Daniel foils the plot, the Alliance sends Jup and Tenat to capture Vala in season 9's "[[The Ties That Bind (Stargate SG-1)|The Ties That Bind]]", but Mitchell and Teal'c double-cross them. Upon meeting and recognizing Mitchell as a scam artist aboard a Lucian Alliance ship in season 10's "[[Company of Thieves (Stargate SG-1)|Company of Thieves]]", Tenat asks for a part of the spoils and is double-crossed again, dying in a self-induced firefight against Netan's mothership. Jup last appears in "[[Bounty (Stargate SG-1)|Bounty]]" as one of several bounty hunters attempting the capture of SG-1 on Earth, but another bounty hunter kills him. * {{anchor|Netan}} Netan, played by [[Eric Steinberg]] (seasons 9–10) – The leader of the Lucian Alliance. He first appears in "[[Off the Grid (Stargate SG-1)|Off the Grid]]", trying to intercept [[Ba'al (Stargate)|Ba'al]] in stealing Stargates from several planets, including one controlled by the Lucian Alliance. Teal'c approaches the Lucian Alliance for help in attacking the invading [[Ori (Stargate)|Ori]] battlecruisers in "[[Camelot (Stargate SG-1)|Camelot]]", and Netan commits three motherships to the battle. After the big losses during that battle, one of Netan's seconds (Anateo) moves against Netan in season 10's "[[Company of Thieves (Stargate SG-1)|Company of Thieves]]", but Anateo's skills and a trick by Mitchell lead Netan to declare war on the people of Earth. SG-1 actually does Netan a favor, killing Anateo for him while retaking the ''Odyssey''. After SG-1 makes raids on Lucian Alliance assets in "[[Bounty (Stargate SG-1)|Bounty]]", Netan places a bounty on the heads of SG-1 and is implied to die at the hands of another bounty hunter himself when the hunters fail. <!--DEAR EDITOR.

==Ori== {{main|Ori (Stargate)}} The Ori are Ascended beings who use their infinite knowledge of the universe to force lesser beings to worship them. In essence, they used to be Ancients, however they split into separate groups due to different views of life. The Ori are religious while the Ancients prefer science. The Ori sway lesser-developed planets into worshipping them by promising Ascension through an invented and empty religion called "Origin". This religion states that they created humanity and as such are to be worshipped by their creations. It also promises its followers that, on death, they will Ascend. However, Origin was designed to channel energy from the human worshippers to the Ori. As such, the Ori never help anyone else Ascend because then they would have to share the power that they sap from their worshippers. Their ultimate goal is to completely destroy the Ascended Ancients, who they know as "the Others". All of their efforts, including their technology, are for the purpose of garnering worshippers. As Ascended beings, the Ori do not interfere directly in the mortal plane. Instead, they use humans called [[Prior (Stargate)|Priors]], which they artificially evolve so that they are one step from Ascension, giving the Priors godly powers. Because the Ori have worshippers across the entire home galaxy of the Ancients, and using their knowledge to spread, they are nearly unstoppable.

The Ori had impregnated [[Vala Mal Doran]] with Adria against her will in season 9 to circumvent the Ancients' rules in the [[Milky Way galaxy]], and as such Vala named the child after her "witch of a woman" stepmother. Losing contact with young Adria in "[[Flesh and Blood (Stargate SG-1)|Flesh and Blood]]", Vala meets her daughter again as an adult in "[[Counterstrike (Stargate SG-1)|Counterstrike]]". In "The Quest", Adria tricks SG-1 into obtaining the Sangraal for her and captures Daniel before he can complete the device. Adria attempts to convert Daniel to the path of [[Origin (Stargate)|Origin]] and makes him a Prior, but he betrays her in "[[The Shroud (Stargate SG-1)|The Shroud]]" and uses the weapon on the Ori galaxy. Adria is briefly implanted with the Goa'uld [[Ba'al (Stargate)|Ba'al]] in "[[Dominion (Stargate SG-1)|Dominion]]", but the removal of the symbiote almost kills Adria and she ascends. She nevertheless continues the Ori's assault on the Milky Way in ''[[Stargate: The Ark of Truth]]'', where the Ancient [[Morgan le Fay (Stargate)|Morgan le Fay]] engages her in an ascended battle, "eternally distracting her from being able to continue her evil ways".<ref name="mythmaker2">{{cite web|last=Sumner|first=Darren|url=https://gateworld.net/news/2008/04/myth-maker-part-2/|title=Myth Maker (Part 2): An Interview With Robert C.

Tomin had been crippled since childhood, and was therefore looked down on by his fellow villagers. Tomin married Vala and accepted her pregnancy as his child, not knowing that it was an immaculate conception set by the Ori. A little later, a Prior visited the village and cured Tomin of his limp, allowing him to become a warrior for the Ori. The prior also told Tomin the truth about the child as "the will of the Ori", who would later be the [[Orici]]. Tomin is later able to forgive Vala.<ref name="Crusade">"[[Crusade (Stargate SG-1)|Crusade]]" (''[[Stargate SG-1]]'')</ref> As seen in "[[Camelot (Stargate SG-1)|Camelot]]", Tomin and Vala depart aboard the first wave of Ori vessels entering the Milky Way, and they go separate ways in season 10's "[[Flesh and Blood (Stargate SG-1)|Flesh and Blood]]". Tomin rises to the rank of commander within the Ori warrior armies, and he and Vala meet again in "[[Line in the Sand (Stargate SG-1)|Line in the Sand]]". Because a Prior twists the words of the Book of Origin, Tomin begins to doubt the Priors and their interpretations of Origin's teachings, and helps Vala escape. Despite his betrayal, Tomin survives and remains an Ori commander by the time of ''[[Stargate: The Ark of Truth]]'', leading the Ori forces in the ruins of Dakara. After the Prior he serves is killed by Mitchell, Tomin finally loses his faith in the Ori and surrenders to SG-1. Tomin helps Daniel decipher his visions of the Ark of Truth and accompanies SG-1 back to the Ori galaxy where Tomin is instrumental in finding the Ark and ending the Ori threat for good. After the defeat of the Ori, Tomin becomes the new leader of his people, but Vala declines Tomin's offer to return with him, feeling that her place is with SG-1.

He first appears in season 9's "[[Origin (Stargate SG-1)|Origin]]", residing in the city of Celestis, with his chambers next to the Ori's ''Flames of Enlightenment''. He also appears in a short flash in "[[The Fourth Horseman (Stargate SG-1)|The Fourth Horseman, Part 1]]" and is hit by the Ark's beam in ''[[Stargate: The Ark of Truth]]'', stopping his belief of the Ori as gods so that he spreads the truth to all of the Priors in the Ori galaxy and through them to their followers. The Doci immediately breaks down in tears, begging for forgiveness for his actions.{{•}} Although Sands' limited availability was a hindrance in ''The Ark of Truth'', the producers felt it was better to include the Doci than to forgo the character.<ref name=mythmaker2 /> Had Julian Sands not been able to resume the role, the producers had planned to hire another actor as a different Doci in charge in Celestis.<ref name="newdirections">{{cite web|author1=Sumner, Darren|author2=Read, David|name-list-style=amp|url=https://gateworld.net/news/2007/06/new-directions-part-1/|title=New Directions (Part 1): An Interview With Robert C.

As a reward for fulfilling his duties and putting Vala through a Trial by Fire, he is transformed into a Prior in "[[Origin (Stargate SG-1)|Origin]]". He is later sent to the Milky Way and appears in "[[The Powers That Be (Stargate SG-1)|The Powers That Be]]" unleashing a plague in a defiant village, in "[[The Fourth Horseman (Stargate SG-1)|The Fourth Horseman]]" turning [[Gerak]] into a Prior, and in season 10's "[[Line in the Sand (Stargate SG-1)|Line in the Sand]]" ordering the destruction of a village by spaceship. In ''[[Stargate: The Ark of Truth]]'', he commands Ori ground forces alongside Tomin during the search for the Ark of Truth. With a Prior disruptor blocking his powers, the Prior is killed by Mitchell with a shot from an Ori staff weapon, proving to Tomin once and for all that the Ori are not gods. * {{anchor|Prior}} Prior, played by Doug Abrahams (seasons 9–10) – A one-eyed Prior introduced in "[[Crusade (Stargate SG-1)|Crusade]]", who cures Tomin of his limp and later informs him of being unable to father children. He is on-board one of the Ori battlecruisers invading the Milky Way in "[[Camelot (Stargate SG-1)|Camelot]]" and is present during [[Adria (Stargate)|Adria]]'s birth in season 10's "[[Flesh and Blood (Stargate SG-1)|Flesh and Blood]]", informing Vala and Tomin of her divine purpose. The Prior nearly kills Daniel Jackson, but he and Vala are rescued at the last second by the ''Odyssey''. In "[[The Quest (Stargate SG-1)|The Quest]]", he accompanies Adria in the search of the Sangraal. He is captured in ''[[Stargate: The Ark of Truth]]'' during an attempt to convince Earth to surrender or face destruction. After the Ark of Truth is retrieved from the Ori home galaxy, the Prior is exposed to it, spreading the truth to all of the Ori followers in the Milky Way galaxy and ending their crusade.
==Replicators== {{anchor|Replicator (Stargate)|Replicator|Replicators}} The Replicators are a potent mechanical life-form who use a quiron-based [[nanotechnology]]. They strive to increase their numbers and spread across the universe by assimilating advanced technologies. They are hostile to all other life and are opposed primarily by the Asgard. In the episode "[[Unnatural Selection (Stargate SG-1)|Unnatural Selection]]", the Replicators had used technology extracted from their Android creator to make shapeshifting, human-form Replicators. While standard Replicators are resistant to energy weapons but can be destroyed by projectile weapons, human-form Replicators are resistant to projectile weapons as well, thanks to the change in their nature from large blocks to smaller units the size of organic cells (cell blocks). In the episode "[[New Order (Stargate SG-1)|New Order (Part 2)]]", an [[Ancient (Stargate)|Ancient]] weapon called the Replicator Disruptor was developed by O'Neill while he still had the knowledge of the Ancients in his mind. It works by blocking the cohesion between the blocks that make up the Replicators. The Replicators in the Milky Way galaxy were wiped out by the Dakara Superweapon in the two-part episode "[[Reckoning (Stargate SG-1)|Reckoning]]" at the climax of Season 8. It has been indicated that the Asgard used the same technology to defeat the Replicators in their own home galaxy as well.
===Fifth=== {{anchor|Fifth}} Fifth, played by Patrick Currie (seasons 6, 8) – A human-form Replicator introduced in season 6's "[[Unnatural Selection (Stargate SG-1)|Unnatural Selection]]". He is the fifth human-form to be created on the Asgard planet Halla, and unlike the others he lacks the programming flaws of the android Reese, on which the human-forms are based. This makes him more "human" than the other Replicators, who consider him "weak" as a result. After SG-1 is captured by the Replicators, Fifth becomes fascinated by them, especially Carter, and attempts to help them, but SG-1 break their promise and leave Fifth behind in a time dilation field. Fifth has escaped the time dilation field in the season 8 episode "[[New Order (Stargate SG-1)|New Order]]", and en route to the new Asgard homeworld of Orilla, he captures Samantha Carter and tortures her in revenge. He eventually relents when she appeals to his humanity again, and professes his love for her. He lets Carter go but creates a Replicator duplicate of her to serve as his consort. Fifth appears for the last time in "[[Gemini (Stargate SG-1)|Gemini]]", conspiring with Replicator Carter to obtain data from the SGC that would immunize them from the Replicator Disruptor. Replicator Carter however never returned his feelings, believing him unfit to command the Replicators. She ultimately betrays him, taking the data for herself while manipulating him into being destroyed by the Disruptor.
Patrick Currie had auditioned for the show about 15 times before being cast, according to Currie, because the producers always short-listed him and waited for the perfect episode to use him in. When preparing for the role of Fifth, Currie was unsure where to take the innocence and vulnerability of the character, and later figured that the key to this character is to know "what it's like before we learn to play games and pretend". He thinks Fifth is a misunderstood character and not a villain; Fifth believes he loves Carter, but lacks comparisons.<ref name="gw_fifthunleashed">{{cite web|last=Read|first=David|url=https://gateworld.net/news/2005/01/fifth-unleashed/|title=Fifth Unleashed: An Interview With Patrick Currie|publisher=[[GateWorld]]|date=January 15, 2005|access-date=2008-12-03}}{{Dead link|date=May 2026 |bot=InternetArchiveBot }}</ref>
===Replicator Carter===
{{Anchor|Replicator Carter|RepliCarter|Replicator}} Replicator Carter (also known as RepliCarter), played by [[Amanda Tapping]] (season 8) – A human-form Replicator created by Fifth. She first appears at the end of "[[New Order (Stargate SG-1)|New Order]]", and becomes a major adversary in the eighth season of the series. Fifth intended her to be a duplicate of the real Samantha Carter, but one who would return his affections. Replicator Carter seemingly defects from Fifth to the SGC in "[[Gemini (Stargate SG-1)|Gemini]]", but in fact abandons him to be destroyed while she develops a means to immunize herself from the Replicator Disruptor. In "[[Reckoning (Stargate SG-1)|Reckoning]]", Replicator Carter launches a full-scale invasion of the Milky Way and personally eliminates the last of the [[Goa'uld]] [[System Lord]]s. She abducts Daniel and probes his mind to find the location of the Dakara superweapon, the only thing in the galaxy capable of stopping her. She also sends Replicators to fight the forces of [[Ba'al (Stargate)|Ba'al]], the [[Jaffa Rebellion]], and Stargate Command on Earth. Daniel Jackson is able to exploit his connection to the Replicator network at a critical moment, buying enough time to finish calibrating and activating the Dakara weapon. The resulting energy wave breaks Replicator Carter and all her brethren into their constituent parts.
==Tok'ra==
The Tok'ra (literally "against [[Ra (Stargate)|Ra]]", the Supreme System Lord) are a faction of Goa'uld symbiotes who are opposed to the Goa'uld culturally and militarily. Spawned by the queen Egeria, they live in true symbiosis with their hosts, both beings sharing the body equally and benefitting from each other. The Tok'ra have fought the Goa'uld for thousands of years, favoring covert tactics and balancing the various System Lords against one another. Since season 2 of ''Stargate SG-1'', the Tok'ra have become valuable allies of Earth.
===Jacob Carter=== {{anchor|Jacob Carter}} [[File:Carmen Argenziano - 2012 Sci-Fi Convention Toulouse 271.jpg|thumb|upright|[[Carmen Argenziano]] played [[Samantha Carter]]'s father Jacob and the [[Tok'ra]] Selmak.]]
Jacob Carter, played by [[Carmen Argenziano]] (seasons 2– 8) – A retired United States Air Force Major General and the widowed father of Samantha Carter and Mark Carter. Jacob Carter is introduced in season 2's "[[Secrets (Stargate SG-1)|Secrets]]" as a [[USAF]] general dying of [[cancer]], and after becoming a willing host of a [[Tok'ra]] named Selmak who would cure his illness ("[[The Tok'ra]]") he frequently recurs as the Tok'ra liaison to Earth. As a member of the Tok'ra High Council, Jacob/Selmak engages in Tok'ra covert operations and provides help to Stargate Command when problems arise. He goes on off-world missions with SG-1, and frequently provides valuable knowledge and expertise, including the ability to use a [[Goa'uld]] healing device. When the Earth-Tok'ra relations deteriorate, Jacob/Selmak remains the strongest link between the allies despite his loss of influence in the Tok'ra High Council. In season 7's "[[Death Knell (Stargate SG-1)|Death Knell]]", Jacob helps his daughter devise the Kull Disruptor as an invaluable weapon in fighting the army of [[Kull Warrior]]s of [[Anubis (Stargate)|Anubis]]'s creation. He also plays a key role in setting the Dakara Superweapon to the right pattern to attack the [[Replicator (Stargate)|Replicators]] in season 8's "[[Reckoning (Stargate SG-1)|Reckoning]]", but Selmak dies of old age one episode later in "[[Threads (Stargate SG-1)|Threads]]", along with Jacob who would not let go of him a few weeks earlier knowing by keeping Selmak alive he would help in the fight against the replicators but would ultimately die with Selmak due to release of a poison when a Symbiote dies. Selmak fell into a coma shortly after the Dakara Superweapon was activated thus preventing him from saving Jacob.
===Martouf=== {{Anchor|Martouf|Lantash|Lieutenant Elliot|Kevin Elliot|Elliot (Stargate)|Lieutenant Kevin Elliot (Stargate)}} Martouf, played by [[JR Bourne]] (seasons 2–4, 9) – A leader in the ranks of the Tok'ra. Martouf had been the mate of Rosha, host to [[Jolinar]], for almost a century. SG-1 first meet Martouf during their first encounter with the Tok'ra in season 2's "[[The Tok'ra (Stargate SG-1)|The Tok'ra]]", and since Jolinar was once blended with Samantha Carter, Martouf develops an interest in her. Some episodes later in "[[Serpent's Song (Stargate SG-1)|Serpent's Song]]", Martouf recommends that [[Apophis (Stargate)|Apophis]], who sought asylum at the SGC, should be handed over to [[Sokar (Stargate)|Sokar]]. In the season 3 two-parter "[[Jolinar's Memories (Stargate SG-1)|Jolinar's Memories]]"/"[[The Devil You Know (Stargate SG-1)|The Devil You Know]]", Martouf joins SG-1 on a mission to rescue [[Jacob Carter]], the host of the Tok'ra Selmak, from [[Ne'tu]]. They are captured and tortured, but Martouf, Selmak and SG-1 can escape when a new Tok'ra weapon destroys Ne'tu. However, Martouf is unwittingly subjected to Goa'uld mind control, turning him into a zatarc. His attempt to assassinate the President of the United States in season 4's "[[Divide and Conquer (Stargate SG-1)|Divide and Conquer]]" ends in failure, and Carter is forced to kill him. Martouf's symbiote, Lantash, survives and is placed in a Tok'ra stasis chamber, which is destroyed in a Goa'uld attack in season 5's "[[Last Stand (Stargate SG-1)|Last Stand]]". The new SGC recruit Lieutenant Elliot (played by Courtenay J. Stevens, season 5) blends with Lantash after a severe injury, but they give their lives to save the rest of SG-1 and the Tok'ra, eliminating the entire Goa'uld invasion force with a vial of symbiote poison. An alternate version of Martouf arrives at the SGC when many SG-1s from alternate realities start coming through the Stargate in season 9's "[[Ripple Effect (Stargate SG-1)|Ripple Effect]]". That universe's Martouf had joined the SGC to be closer to Carter, but their relationship did not last.
According to portraying actor Courtenay J. Stevens, the first draft for the character was that he was supposed to be a young [[Jack O'Neill]] in the then new [[Spin-off (media)|spin-off]] show ''[[Stargate Atlantis]]''. The producers dropped Elliot and minimized his role so that he was never even mentioned in ''Stargate Atlantis''. Many fans of ''Stargate'' thought that Elliot and his team would replace [[Samantha Carter]], [[Teal'c]], [[Daniel Jackson (Stargate)|Daniel Jackson]] and O'Neill as the [[main characters]] of the show. Stevens has stated that the producers took much time to look at new "Options", for the series and further stated that he knew "they were looking at it". But the plans were changed and actor Stevens left the ''Stargate'' set in [[Vancouver]] after the shooting of "[[Last Stand (Stargate SG-1)|Last Stand]]". When shooting the episode, "[[Summit (Stargate SG-1)|Summit]]" [[J.R. Bourne]] was booked, so he was replaced with Stevens. Before being cast in the episode "Summit", the producers told the history behind the [[Tok'ra]] symbiote [[Lantash]]. Stevens was later cast as Keras in the ''Stargate Atlantis'' episode "[[Childhood's End (Stargate Atlantis)|Childhood's End]]".<ref name="courtenayjstevensinterview">{{cite web|last=Read|first=David|url=https://gateworld.net/news/2004/08/chillin-with-elliot/|title=Chillin' With Elliott: An Interview With Courtenay J.

In season 4's "[[Absolute Power (Stargate SG-1)|Absolute Power]]", Aldwin is sent to the SGC to verify via a zatarc-detecting device that [[Shifu (Stargate)|Shifu]] is indeed the supposed Harcesis. Alwin is killed in season 5's "[[Summit (Stargate SG-1)|Summit]]"/"[[Last Stand (Stargate SG-1)|Last Stand]]" when [[Zipacna (Stargate)|Zipacna]] attacks the planet Revanna where Aldwin guided SG-17 through the Tok'ra base. * {{Anchor|Anise|Freya}} Anise, played by [[Vanessa Angel (English actress)|Vanessa Angel]] (season 4) – A gifted scientist and historian whose human host Freya is attracted to Jack O'Neill, although the symbiote prefers Daniel Jackson, as stated in season 4's "[[Divide and Conquer (Stargate SG-1)|Divide and Conquer]]". She is introduced in season 4's "[[Upgrades (Stargate SG-1)|Upgrades]]", researching the Atanik armbands on SG-1 in the hope to use the armbands' powers on a dangerous SG-1 mission to destroy [[Apophis (Stargate)|Apophis]]' new prototype mothership. Anise is present for [[Tanith (Stargate)|Tanith]]'s introduction in "[[Crossroads (Stargate SG-1)|Crossroads]]", and assists Stargate Command in "[[Divide and Conquer (Stargate SG-1)|Divide and Conquer]]" to uncover possible Zatarcs within the SGC ranks.

In "[[Enemies (Stargate SG-1)|Enemies]]", she travels to Earth to inform General Hammond that, though their plan to destroy [[Apophis (Stargate)|Apophis]]' fleet was successful, no trace of SG-1 or Jacob/Selmak has been found. In "[[Summit (Stargate SG-1)|Summit]]", Ren'al briefs the SGC on an upcoming summit of the [[Goa'uld]] [[System Lord]]s and the Tok'ra plan to assassinate them using symbiote poison. When the Tok'ra base on Ravenna comes under attack by Anubis' minion [[Zipacna (Stargate)|Zipacna]] in "[[Last Stand (Stargate SG-1)|Last Stand]]", Re'nal is killed by falling debris.
== Tollan== {{anchor|Tollan}} The Tollan are an advanced human civilization who are introduced in season 1's "[[Enigma (Stargate SG-1)|Enigma]]" when the SGC helps a group of them relocate from the original Tollan homeworld that had undergone catastrophic volcanic activity. The [[Nox (Stargate)|Nox]] take the Tollan in while they continue to search for a new home, later revealed to be named Tollana. The Tollan have a strict policy against sharing technology with more "primitive" races, instituted after such a transfer caused the civilization of their neighboring planet Serita to destroy itself in a single day.<ref name="Enigma">{{cite episode|title = Enigma| episode-link = Enigma (Stargate SG-1)| series = Stargate SG-1| series-link = Stargate SG-1}}</ref> Teal'c notes in season 3's "[[Pretense (Stargate SG-1)|Pretense]]" that despite the Tollans' technological superiority, they "do not think strategically". The Tollan are wiped out by the forces of the Goa'uld [[Tanith (Stargate)|Tanith]] in season 5's "[[Between Two Fires (Stargate SG-1)|Between Two Fires]]" after the Goa'uld [[Anubis (Stargate)|Anubis]] developed shields impervious to Tollan weaponry.
* {{anchor|Narim}} Narim, played by [[Garwin Sanford]] (seasons 1, 3, 5) – An influential Tollan who befriends SG-1 after they save him and a group of fellow Tollans in "[[Enigma (Stargate SG-1)|Enigma]]". He develops an apparent attraction to Carter and reconfirms his feelings for her in "[[Pretense (Stargate SG-1)|Pretense]]", although she informs him that she is not looking for a relationship at that time. After the death of the Tollan leader, Omoc, in "[[Between Two Fires (Stargate SG-1)|Between Two Fires]]", Narim and SG-1 discover that his government was collaborating with the Goa'uld. Narim takes action to spare Earth from destruction, but the Goa'uld begin attacking the planet. Narim escorts SG-1 to the Stargate and stays behind to help his people fight. Shortly afterwards, Narim informs Earth of Tollana's devastations via a transmission, which ends abruptly. * {{anchor|Travell}} Travell, played by Marie Stillin (seasons 3, 5) – High Chancellor and a member of the Curia, the Tollan's highest ruling body. She is first seen in "[[Pretense (Stargate SG-1)|Pretense]]", where she presides over the hearings about the future of the Goa'uld [[Klorel]] and his unwilling host [[Skaara]]. In season 3's "[[Shades of Grey (Stargate SG-1)|Shades of Grey]]", Travell participates in an undercover operation conducted by the SGC to expose the rogue [[NID (Stargate)|NID]] agents as thieves. In Travell's final appearance in "[[Between Two Fires (Stargate SG-1)|Between Two Fires]]", she offers Tollan ion cannon technology to Stargate Command, later discovered to be part of Tanith's extortion of the Curia.
==Other alien recurring characters== * {{anchor|Cassandra}} Cassandra, played by [[Katie Stuart]] (seasons 1–2), Pamela Perry (season 2, old woman), and [[Colleen Rennison]] (who also played Ally in the S02E10"Bane") (season 5) – A young girl whom SG-1 discovers in season 1's "[[Singularity (Stargate SG-1)|Singularity]]" as the sole survivor of a biological plague on the planet Hanka, and whom Janet Fraiser subsequently adopts. A naqahdah bomb that the Goa'uld [[Nirrti (Stargate)|Nirrti]] once planted in Cassandra's chest shuts down on its own and is eventually absorbed into her body's tissues, allowing Cassandra to sense the people who are infested, or blended with, a [[Goa'uld]]. As such, Cassandra senses Carter to have been taken over by [[Jolinar]] in season 2's "[[In the Line of Duty (Stargate SG-1)|In the Line of Duty]]". In season 5's "[[Rite of Passage (Stargate SG-1)|Rite of Passage]]", a retrovirus Cassandra contracted on her home planet several years ago causes her to evolve into a ''hok'taur'' (an advanced human being), but SG-1 makes a deal with Nirrti to save Cassandra's life. After Janet Fraiser's death in season 7's "[[Heroes (Stargate SG-1)|Heroes]]", Carter promises to inform Cassandra about what happened to her adopted mother. Travelling from the year 1969 to several decades into the future, SG-1 meets Cassandra as an old woman in season 2's "[[1969 (Stargate SG-1)|1969]]", who helps them return to their own time. In season 9, Carter mentions that Cassandra is going through a hard time. * {{anchor|Chaka}} Chaka, played by Dion Johnstone (seasons 4–5) and by Patrick Currie (season 7) – A young [[Unas (Stargate)|Unas]] from P3X-888 who captures Daniel in season 4's "[[The First Ones (Stargate SG-1)|The First Ones]]" to prove his maturity to his tribe. When the two learn to communicate, Chaka kills his tribe's existing Alpha male and rises to become the new leader. After SG-1 frees Chaka from slave dealers in season 5's "[[Beast of Burden (Stargate SG-1)|Beast of Burden]]", Chaka chooses to remain behind to lead an ultimately fragile but successful fight for the freedom of his fellow Unas. Chaka last appears in season 7's "[[Enemy Mine (Stargate SG-1)|Enemy Mine]]" to negotiate between a large group of aborigine Unas and SGC personnel, whose naqahdah mining operations on the Unas planet unwittingly encroached on holy Unas ground.{{•}} When Dion Johnstone was unavailable to play Chaka in "Enemy Mine", Patrick Currie (who had previously been cast to play [[Fifth (Stargate)|Fifth]]) prepared for the role by watching Johnstones's previous performances. Director [[Peter DeLuise]] told Currie to follow Dion's lead but to add his own spin to the character. Playing an Unas is a challenging job as it requires a full prosthetic body-suit, contact lenses, and fake teeth.<ref name=gw_fifthunleashed /> * {{anchor|Dreylock|Langarans}} Dreylock, played by [[Gillian Barber]] (seasons 6–7) – A high ranking Kelownan official from Jonas Quinn's home planet Langara, and a Kelownan ambassador to other nations and planets. She approaches Earth in season 6's "[[Shadow Play (Stargate SG-1)|Shadow Play]]" to obtain more advanced military technology against Kelowna's two rival nations, but the SGC refuse to share their technology.

Drugged with [[pharmaceutical]]s by his comrades, Martin loses his memories and becomes a paranoid conspiracy theorist who learns of the [[Stargate Program]]. In season 4's "[[Point of No Return (Stargate SG-1)|Point of No Return]]", O'Neill helps Martin to slowly regain his memory, and Martin chooses to remain on Earth. By season 5's "[[Wormhole X-Treme!]]", Martin has become so disgruntled with his life that he starts taking the drugs again. His latent memories inspire him to create a [[Camp (style)|campy]] science fiction television show, ''Wormhole X-Treme!'', based on the real Stargate program and SG-1, and O'Neill helps Martin recover his memories once again. A ship approaches Earth to pick up Martin's former comrades, but Martin chooses to stay behind to continue working on ''Wormhole X-Treme!'' as a creative consultant. As becomes known in season 10's "[[200 (Stargate SG-1)|200]]", Martin's show only aired for three episodes but had high DVD sales. Martin approaches the SGC to review a script for a television movie based on the series, and although the movie is eventually cancelled, the series is renewed, ultimately lasting ten years with Martin Lloyd as producer. * {{anchor|Lya}} Lya, played by [[Frida Betrani]] (seasons 1, 3) – A [[Nox (Stargate)|Nox]] woman. She first appears in season 1's "[[The Nox (Stargate SG-1)|The Nox]]", where her family brings her back from the dead after one of [[Apophis (Stargate)|Apophis]]' [[Jaffa (Stargate SG-1)|Jaffa]] killed her. In season 1's "[[Enigma (Stargate SG-1)|Enigma]]", Lya offers the Tollan sanctuary with the Nox. In season 3's "[[Pretense (Stargate SG-1)|Pretense]]", Lya serves as the neutral attorney at a Tollan hearing and eventually gives the deciding vote to remove the Goa'uld [[Klorel]] from his host [[Skaara]]. Lya also enables the Tollan to repel a Goa'uld attack. * {{anchor|Shifu|Harcesis}} Shifu, played by Lane Gates (season 4) – The son of [[Sha're]] and of the host of the Goa'uld [[Apophis (Stargate)|Apophis]], conceived while Sha're was the host to the Goa'uld Amonet. Apophis intended him as his new host. As the offspring of two human hosts, Shifu possesses the Goa'uld genetic memory and is referred to as "Harcesis". After his birth in season 2's "[[Secrets (Stargate SG-1)|Secrets]]", the boy is hidden safely on [[Abydos (Stargate)|Abydos]] until Amonet discovers him in season 3's "[[Forever in a Day (Stargate SG-1)|Forever in a Day]]". She sends him to Kheb to keep him safe from the Goa'uld who want the child killed. In season 3's "[[Maternal Instinct (Stargate SG-1)|Maternal Instinct]]", SG-1 finds and leaves him there in the care of a powerful energy being called [[Oma Desala]]. In season 4's "[[Absolute Power (Stargate SG-1)|Absolute Power]]", SG-1 encounters Shifu on Abydos and invites him to Earth. After SG-1 acknowledges that Shifu would never reveal his genetic knowledge, Shifu [[Ascension (Stargate)|ascends]]. In season 4's "[[Absolute Power (Stargate SG-1)|Absolute Power]]" Dr. Daniel Jackson translates ''Shifu'' into English as "light"; however, in [[Chinese language|Chinese]] the word ''shifu'' also means "teacher". In the same episode, Shifu says that all he is doing is teaching Daniel. * {{anchor|Kull Warrior|Kull Warriors|Supersoldiers|Supersoldiers}} Kull Warriors (also known as Supersoldiers), played by [[Dan Payne]] and [[Alex Zahara]] (seasons 7–8) – Creatures created by [[Anubis (Stargate)|Anubis]] for use as his personal army against minor Goa'uld. The Kull Warriors first appear in the two-part episode "[[Evolution (Stargate SG-1)|Evolution]]", where seemingly none of the weapons of SG-1 or the [[Jaffa (Stargate)|Jaffa]] are effective against them. In "[[Death Knell (Stargate SG-1)|Death Knell]]", [[Samantha Carter]] and [[Selmak]] develop a prototype weapon designed to counteract the energy animating the Kull Warriors. After the apparent defeat of Anubis in "[[Lost City (Stargate SG-1)|Lost City]]", [[Ba'al (Stargate)|Ba'al]] gains control of the Supersoldiers and thus a significant advantage over his rivals. As a result, in the episode "[[New Order (Stargate SG-1)|New Order]]" the other System Lords approach Earth for a new military arrangement. A simulated invasion of Stargate Command by Kull Warriors is the main premise of the episode "[[Avatar (Stargate SG-1)|Avatar]]". In "[[Threads (Stargate SG-1)|Threads]]", the remaining Kull Warriors become aimless and confused after Anubis' final defeat, and are easily dispatched. The Kull Warriors make one appearance in the ''[[Stargate Atlantis]]'' episode "[[Phantoms (Stargate Atlantis)|Phantoms]]", where they are [[hallucination]]s caused by a [[Wraith (Stargate)|Wraith]] device. The Kull Warriors were conceived as a much more powerful adversary than the Jaffa, and one that would be more palatable to fight.<ref>Interview with Robert C. Cooper. ''SFX Magazine'' (May 2003)</ref> The art department developed the final concept while "Evolution" was written; in the original plans, the face looked a lot like that of the [[Borg]], which eventually developed into the idea of the fiber-optic network that ran over the skull. The motion of the Kull Warrior was deliberately styled to be unique and not resemble other robotic characters, such as [[RoboCop]], the Borg, or human-form [[Replicators (Stargate)|Replicators]].<ref>Interview with Dan Payne. ''Gateworld.com'' (September 2006)</ref> Dan Payne described the suit as the most functional, mobile full-body unit he has ever been in. It took 15 to 30 minutes to get him into the suit, making him about seven feet tall due to the helmet and the boots.<ref name="kull_special">Dan Payne in a DVD special about the creation of the Kull warriors.</ref>
