The Tau'ri

    In General 

The humans of Earth. The Goa'uld enslaved many of them in ancient times and spread them across the galaxy to serve them, so all Milky Way humans are descended from the Tau'ri. Over the course of the series, they manage to take down powerful evil alien after powerful evil alien. Their technology gradually catches up to other races and they eventually become a major galactic superpower. And yet, most of them have no idea that any of this is going on.


  • The Alliance: Part of their mission is to establish diplomatic relations, so they form multiple alliances over the course of the series. The most prominent one is between them, the Tok'ra and the Free Jaffa, with the Tau'ri being at the center.
  • Benevolent Precursors: To the rest of the humans in the galaxy, since they were all transplanted from Earth, and were thus descended from the Tau'ri. They've freed plenty of worlds from their enemies, and when one of their allies calls for help, they won't hesitate to lend a hand.
  • Big Good: They slowly evolve into this over the course of the series.
  • Boring, but Practical: Much of their technology fall under this, especially compared to the Goa'uld. An example is their weapons, which Teal'c calls "primitive, but effective".
  • Crazy-Prepared: Compared to the rest of the galaxy, they don't take chances in anything to do with the Stargate. They've built the most secure facility on the planet around it and stocked it with trained soldiers, brilliant scientists and all the supplies they need. They also send remote probes to worlds they've never been to so they can be prepared for whatever's on the other side.
  • Destructive Saviour: The Tok'ra see them this way because every time they kill an evil enemy, another even worse one steps in to take their place. The Tau'ri cause the Goa'uld's downfall in less than a decade, but not without collateral damage that the Tok'ra were trying to avoid.
  • Enemy Mine: They will do this to wipe out a common enemy when they have to. Sometimes it results in a lasting alliance, like with the Unas (in an episode actually called "Enemy Mine"), while others, they go right back to being enemies afterwards, like with System Lords Yu and Ba'al.
  • Humans Advance Swiftly: They do this through reverse-engineering of Imported Alien Phlebotinum.
  • Humans Are Special: They are not shown to be particularly smarter, stronger, faster or more "imaginative" than other species, but the Asgard point out that they have great potential.
  • Humans by Any Other Name: It was originally the Goa'uld word for their planet, but came to refer to the humans of Earth. Though humans in general are still just called humans.
  • Muggles Do It Better: Less advanced technology can be very effective if you use it the right way. How else do you think they manage to defeat the Goa'uld, the Replicators and the Ori?
  • Nice Job Breaking It, Hero!: Every so often when they visit to another world, they cause a new problem just because of something no one saw coming. On more than one occasion, they almost destroyed an entire world of humans. Fortunately, they're also usually the ones who fix whatever problem pops up.
  • Outside-Context Problem: To the Goa'uld. They had a nice little system set up where they could squabble with one another, had a treaty with the Asgard to keep them off their backs, run their own little kingdoms as they wanted... and then a small group of primitives from a long-forgotten world shows up and proceeds to kick their asses so hard that a system that survived millennia goes down in under a decade.
  • Planet Terra: The Ancients actually called their planet Terra. Of course, Latin is derived from their language.

    Catherine Langford
First Appearance: Stargate (1994)

Catherine was the daughter of the archaeologist who discovered the first Earth Stargate, and was later responsible for hiring Daniel to translate the symbols. She was on good terms with the whole team, and eventually died offscreen in season 8 after a long absence from the show.


  • Bus Crash: Her last appearance on the show is towards the end of season 2, and she's barely mentioned again until her death is announced in the season 8 finale two-parter.
  • Cool Old Lady: Jack and Daniel both clearly adore her, she went toe-to-toe with General Hammond in a verbal sparring match, and she even went through the Stargate to retrieve her long-lost fiance while barely batting an eye.
  • Good Luck Charm: Her Eye of Ra pendant, which she loans to Daniel for the duration of the movie. He sends it back to her with O'Neill after deciding to stay on Abydos, and she later leaves it to him along with most of her other possessions after her death.
  • Herald: She's the one who recruits Daniel for the first mission in the movie.
  • Like a Son to Me: Her niece claims at her funeral that she considered Daniel to be the son she never had.
  • Personal Effects Reveal: She leaves Daniel her entire archaeological collection after her death, which kickstarts the events of "Moebius" after he stumbles across evidence of a ZPM on Earth.

    Major Paul Davis
Played By: Colin Cunningham
First Appearance: "A Matter of Time"

A by-the-book air force officer who served as the official liaison between the Pentagon and Stargate Command. Tended to show up just to let the SGC know when they had a crisis on their hands. Also helped them when they came into conflict with other countries or other branches of the US government.


  • And Mission Control Rejoiced: He's usually shown cheering in the control room after the team manages to avert whatever crisis inevitably follows his arrival.
  • Badass Bureaucrat: After spending a little time around the SGC and getting a better idea of what's at stake, he learns to use his bureaucratic skills to help the SGC.
  • Badass Moustache: Had one in an alternate timeline only.
  • Bearer of Bad News: He is nicknamed "Disaster Davis" by the fans, as he usually appears with bad news, sometimes at bad times with even worse news. This is justified by the nature of his character, however. He's the liaison between the Pentagon and Stargate Command, so he is really only ever sent when the Pentagon has bad news.
  • Chuck Cunningham Syndrome: Completely disappears from the narrative after season 8, though he has a brief walk-on cameo at the start of Continuum and returns for the Atlantis finale. He's also absent from the last three episodes of Season 7 despite them heavily involving political and bureaucratic elements that he had been the main character for previously.
  • Guile Hero: He's (usually) not a fighter. Words and negotiation are his weapons, which comes in handy when the SGC comes into conflict with other people on Earth.
  • Majorly Awesome: Doesn't often see action, but he can display this trope if the moment calls for it.
  • Non-Action Guy: Usually, though he does get in on the action on occasion. The most notable example being the episode where he accompanies the team to retrieve a Goa'uld Ghost Ship in orbit around Earth, which they wind up crashing into the ocean.
  • Obstructive Bureaucrat: A mild version in his first few appearances. He was never nasty like Woolsey and his ilk, and mostly seems genuinely apologetic when he has to put the brakes on the SGC's latest mad scheme, just overly obsessed by red tape, and he grows out of it after enough exposure to the SGC.
  • The Political Officer: In his first episode, he is introduced as the official liaison between Washington and the SGC, in a much more sympathetic portrayal than most examples.
  • Rank Up: Averted, despite his first and last appearances being over a decade apart. Considering the rules of military promotions and how good he is at his work, he should be a colonel by now.
  • Real Politik: He's often the character used to show the implications of the Stargate and how it would affect international politics. In "48 Hours", he's angered by the Russians' attempt at reneging on their promises and adamantly opposed to giving them the know-how to build naquadah reactors out of fear who the Russians will sell it to. His fear is understandable; as he puts it, a single naquadah nuke would be enough to wipe out a hefty chunk of the United States, imagine if a terrorist got their hands on one.

    Colonel Chekov
Played By: Gary Chalk
First Appearance: "The Tomb"

A Russian Air Force colonel who was implied to have been upper management during the Russians' abortive attempt at a parallel stargate program in "Watergate". Chekov first appeared in the aftermath of a disastrous joint SGC-VKS operation to infiltrate the tomb of the slain System Lord Marduk during which all but one Russian team member was killed. He and Jack didn't get along, though he had fairly good relations with Daniel. Later episodes essentially established him as the Russian Air Force liaison to the SGC. "Crusade" saw him take command of the Daedalus-class battlecruiser RFS Korolev on her maiden voyage. He was killed in battle along with his entire crew.


  • Cultural Posturing: O'Neill tends to bring this out of him.
  • Going Down with the Ship: In command of the Korolev when she was lost with all hands after taking two direct hits from an Ori mothership's Wave-Motion Gun.
  • Hypocrite: Often called the American government, and the people at the SGC by extension backstabbing liars. Takes one to know one buddy.
  • Manipulative Bastard: He has no compunctions about manipulating political situations to his benefit, his saving grace being the fact that he quite openly admits to doing so.
  • No Name Given: We never did find out his given name.
  • Realpolitik: A friendlier version than most. Chekov was all in favor of the stargate tech-sharing agreement between the United States and Russian Federation, but notes in "Disclosure" that it's partly because taking a backseat to the US means that Russia can let the SGC shoulder most the budgetary burdens of adapting alien technology. He also helped foil a Goa'uld attempt to start World War III in "Full Alert," which needs no explanation.
  • Russian Guy Suffers Most: It's something of a bone of contention for him that whenever SG-1 joins forced with a Russians team, the Russians invariably get slaughtered while SG-1 remains unscathed.
  • What the Hell, Hero?: Repeatedly calls out the Americans on dragging their feet in regards to exchange of technologies gathered through the stargate program. Though considering all the nasty backstabbing things his government often did, makes his arguments all seem very hypocritical.

    Agent Malcolm Barrett
Played By: Peter Flemming
First Appearance: "Wormhole X-Treme!"

An agent of the National Intelligence Department (NID), The Men in Black branch of the government that oversees top-secret projects. Though the NID have a reputation for being shadowy and corrupt, Agent Barrett had no part in the rogue agents that operated outside the law, so he helped the SGC when they needed it. Had an interest in Samantha Carter that was not reciprocated.


  • Badass in a Nice Suit: Due to him being one of The Men in Black. As he once said regarding his suit, "Black is good for any occasion."
  • Brainwashed and Crazy: He falls victim to brainwashing by Ba'al in season 9, though he eventually makes a full recovery.
  • By-the-Book Cop: The main reason that the team even realize he's been brainwashed is that he suddenly starts acting rogue, when normally he's painstakingly by the book about everything.
  • Dogged Nice Guy: Downplayed towards Carter. She's aware of his interest in her and gently turns him down whenever he brings it up, but he generally doesn't push and they remain good friends.
  • Hero of Another Story: In seasons 9 and 10, while the SGC is fighting the Ori, Barrett leads the NID's war against the Goa'uld-controlled Trust on Earth.
  • Jurisdiction Friction: Occasionally occurs as a result of the NID having different goals to the SGC.
  • Overt Rendezvous: In "Smoke and Mirrors", he and Carter meet in the park because all conversations in his office are recorded.
  • Token Good Teammate: He's the only decent NID agent we ever meet, there to remind us that it's a legitimate organization with an unfortunate rogue element.
  • Took a Level in Kindness: His first appearance has him practically take Carter and Daniel hostage, but he mellows out a lot after he and Sam work a case together and he's on good terms with the entire team by the end of the series.

    Dr. Rodney McKay
Played By: David Hewlett
First Appearance: "48 Hours"

A brilliant but massively egotistical scientist who was initially brought in by Colonel Simmons to help Carter out when Teal'c was stuck in the Stargate's memory buffer. He showed up a few times after that before joining the Atlantis expedition — though even after the beginning of Atlantis he would occasionally pop up in an alternate universe.

Go here for tropes applying to McKay in Atlantis.


  • Always Someone Better: He admits to feeling this way about Carter in the season 6 premiere.
  • Belligerent Sexual Tension: Played for Laughs. He thinks this is the dynamic he has going with Carter, but she genuinely can't stand him... until the end of "Redemption", when they sort-of become friends and she claims she found him more attractive when she hated him.
  • Insufferable Genius: He genuinely is brilliant, but he also knows it, and he's extremely obnoxious about it. He does mellow out a bit after he ignores Carter's warnings and makes a situation infinitely worse.
  • Jerk with a Heart of Gold: He starts to display his softer side around his second appearance, though this trope isn't fully realized until Atlantis.
  • Reassigned to Antarctica: He gets reassigned to Siberia at the end of his first appearance in order to help the Russians with their new naquadah generators.
  • Technician vs. Performer: Technician to Carter's Performer. He explicitly identifies this as the difference between their approaches in "Redemption", and claims that she'll always be better than him as a result.
  • Teeth-Clenched Teamwork: Usually crop up whenever he and Sam have to work together, though it's downplayed in his later appearances.
  • Transplant: To Atlantis.

    Julia Donovan 
Played By: Kendall Cross
First Appearance: "Prometheus"

A reporter who hosted a news show called !nside Access. She found evidence of the Prometheus project and tried to uncover the truth before the government intervened. In the end, she was offered an exclusive, provided that she revealed her sources and didn't go public before the government said so.


  • Conspiracy Theorist: She's right about there being a conspiracy of a secret military project called Prometheus, but she believes it's some kind of fusion reactor. Whether she's right or not, she's still determined to find the truth.
  • Deadman Switch: Donovan claims that if "anything were to happen to her", she has plans in place for her story to be released immediately.
  • Determinator: She refuses to back down on her search for the truth. She only agreed to keep it a secret when the network gave in to government pressure with the possibility of Donovan getting charged with treason.
  • Entertainingly Wrong: She initially believes that Prometheus was a fusion reactor and had nothing to do with interplanetary travel.
  • Intrepid Reporter: She's a reporter who actively goes looking for top stories like Prometheus, but she probably didn't expect her intrepidness to take her all the way into outer space.
  • Lucky Charms Title: Her show is written as !nside Access, with an exclamation point in place of the letter I.
  • Secret Keeper: In exchange for a tour of the facility, she signed a non-disclosure agreement about all things related to the Stargate. She would occasionally pop up in later episodes and use her show to help hold up The Masquerade.
  • Token Good Teammate: To her camera crew when they boarded the Prometheus. They all appeared good and trustworthy people, but they turned out to be rogue NID agents who ended up double-crossing her once they were aboard.
  • Unwitting Pawn: The rogue NID used her to gain access to Prometheus so they could travel to a certain world where they knew a weapons cache was waiting for them.
  • The Watson: The viewers learn a lot about what the X-303 was and how it worked through her ears.

    Detective Pete Shanahan
Played By: David DeLuise
First Appearance: "Chimera"

A Denver cop and Carter's boyfriend — later fiance — for most of season 7 and 8. He found out about the Stargate Program after following Carter to a stakeout and witnessing Osiris shooting up a street in broad daylight. Managed to avoid the Cartwright Curse, but Sam ultimately called the wedding off in favor of possibly resolving her UST with O'Neill.


  • Broken Masquerade: Finds out about the whole "aliens are real" thing at the end of his first appearance. He copes pretty well, for the most part.
  • Disposable Fiancé: Sam ditches him in "Threads" after her dying father encourages her to go after what she really wants.
  • Fake Kill Scare: He gets hit during the firefight with Osiris and Sam promises to tell him the truth about her job if he pulls through, which naturally makes the audience suspect he's a goner... Then we cut to him recovering in the VIP room, where Carter follows through on that promise.
  • Former Teen Rebel: He claims at one point that he had a troubled youth and would have ended up in jail if not for another cop who took an interest in him.
  • Fourth Date Marriage: Proposes to Sam when they've only been going out for a few months. Ultimately subverted, as they don't go through with it.
  • Friend on the Force: A weird version since Sam's security clearance goes a lot higher than his, but his cop skills come in handy on at least one occasion when Teal'c is falsely suspected of murder.
  • Romantic False Lead: He's the first long-term Love Interest Sam has (the only one really, unless you count O'Neill), and for a while it looks as though the marriage might actually go ahead, but alas, it wasn't meant to be.
  • Sherlock Scan: He does this in his first scene, though he's roleplaying at the time.
  • Stalking Is Love: He has a background check done on Sam and then follows her to a stakeout after growing suspicious about her job. She doesn't seem to hold a grudge over either.
  • Understanding Boyfriend: He becomes this after finding out what Sam's job really entails.

    President Henry Hayes
Played By: William Devane
First Appearance: "Inauguration"

The new President who got voted into office at the end of season 7, replacing the Invisible President of previous seasons. An affable sort of fellow but by no means a pushover, he implemented a series of changes after finding out about the Stargate Program, including the appointment of Dr. Weir as its new leader.


  • Back for the Finale: He has a fairly major supporting role for a three episode arc at the end of season 7 before going back to operating mostly behind the scenes, but he reappears as a secondary character in Continuum.
  • Badass Boast: Gives a rather nice one to Kinsey.
    Hayes This is my office, not yours. No matter what you may think you did to make this happen, don't you ever—for one second—forget that.
  • Big Good: Leads pretty much all of Earth during its darkest hour. Technically serves as this through the rest of rest of the series, not to mention Atlantis and Universe even if it's from offscreen.
  • Big "SHUT UP!": When he finally has enough of Kinsey:
    Hayes: Would you shut the hell up?!
  • Catchphrase: He tends to respond to anything he doesn't want to hear, from an attempt to turn down a job offer to a threat of annihilation, with a vehement "Never. Going. To happen."
  • Deal with the Devil: He comes to view his choosing Kinsey to be his running mate as this once he realizes just where most of that campaign funding came from.
  • Did You Just Flip Off Cthulhu?: Gives a cheerful 'I don't think so' to Anubis' Kneel Before Zod routine, then offers to discuss Anubis' terms of surrender. Anubis is partly flabbergasted, partly amused by it.
  • Ham-to-Ham Combat: When he goes up against Anubis's hologram in the Oval Office.
    Anubis: You bring destruction upon yourselves.
    Hayes: Never. Going. To happen. (To his aides) ...Too much?
  • In Its Hour of Need: Refuses to evacuate to the Alpha Site during Anubis' attack on Earth. Instead he decides, for better or worse, he's gonna ride out the storm in the White House.
  • No Party Given: It's never revealed what party he belongs to, though the popular fanon that Kinsey is a Republican would also make him Republican by default.
    • Also in his very first scene he is seen wearing a red tie. A small detail perhaps, but it is the republican colour, and the sort of key indicator that costumer designers often incorporate.
  • "Not Making This Up" Disclaimer: After briefing Weir on the Stargate Program, Kinsey hands her a note from Hayes that just reads "THIS IS NOT A JOKE" with his signature. This is a Brick Joke to his own reaction to it in the preceding Clip Show.
  • Nothing Personal: He makes it clear that his decision to replace Hammond is purely political and that he has nothing but appreciation for the job Hammond has done.
  • Our Presidents Are Different: Mostly President Personable, with just a dash of President Iron.
  • Reasonable Authority Figure: Most of the time. He does make a few questionable decisions, but he's always willing to at least listen to reason.

    James Marrick 
Played By: Currie Graham
First Appearance: The Ark of Truth

A CIA Black Ops agent turned IOA operative who replaces Richard Woolsey as the IOA representative watching over Stargate Command.


  • And I Must Scream: Gets hollowed out and turned into a Replicator-infested puppet. When Mitchell temporarily frees him from Replicator control, Marrick begs him to kill him.
  • Asshole Victim: He’s a manipulative, arrogant dick, though being hollowed out by the Replicators was pretty gruesome.
  • Creepy Monotone: After getting taken over by the Replicators.
  • Dem Bones: After his skin is burnt off by an explosion, his now-metallic skeleton still goes after Mitchell.
  • Grand Theft Me: A Replicator burrows into him and essentially hollows him out to take control of his nervous system.
  • Summon Bigger Fish: Under orders from the IOA, he plans to use Replicators genetically engineered to be even more dangerous than they already were to destroy the Ori ships and then deactivate the Replicators. As is to be expected, this backfires horribly.
  • Smug Snake: He clearly has a high opinion of himself.
  • Too Dumb to Live: His entire scheme with using the Replicators to destroy the Ori was a blatantly terrible idea, and winds up getting him turned into a puppet for the Replicators.



    In General 

Abydos was the first planet visited in the original movie, by a team including Jack O'Neill and Daniel Jackson, among others. The culture was similar to Ancient Egyptian and didn't have much to offer Earth in terms of military value, but both Jack and Daniel had strong emotional ties its people, with the latter even living there for a year between the movie and the series after marrying a local woman. The planet was revisited a few times over the course of the series, before ultimately being destroyed by Anubis in the season 6 finale.


  • Ascend to a Higher Plane of Existence: Oma Desala ascends the entire population when the planet is destroyed. It's implied that this is intended to be a favor to Daniel after she stopped him from attacking Anubis.
  • Bittersweet Ending: They get to ascend and live out eternity in peace, but on the other hand their entire planet is destroyed and they're still technically dead.
  • Earth-Shattering Kaboom: As a result of Anubis bombarding the planet from space.
  • Kick the Dog: Falls victim to this when Anubis decides to destroy the planet pretty much because he can.
  • Last Stand: All the able-bodied men in the community pick up arms to help fend off Anubis's forces while the team search for a way to stop him.
  • Where It All Began: As it's where the movie that started it all took place, the planet gets revisited in what was originally intended to be the Grand Finale but ended up being a Series Fauxnale instead.

Played By: Mili Avital (movie), Vaitiare Bandera (SG-1)
First Appearance: Stargate

Daniel's wife, who he met during the first mission to Abydos in the movie. After a year of marital bliss, she was kidnapped by Apophis to become a host for his mate Amaunet, kickstarting a significant plot thread for the first three seasons. She was eventually killed by Teal'c to save Daniel's life in a Shoot the Dog situation, but not before she gave birth to Apophis's "son", the Harcesis child.


  • Adaptation Name Change: From "Shau'ri" in the movie to "Sha're" in the series. Michael Shanks apparently had trouble pronouncing the original spelling.
  • And I Must Scream: Applies to all Goa'uld hosts, but especially of note in her case as she's forced to endure Apophis raping her while being unable to do anything about it. Also, the scene from the pilot when she's turned into a host; imagine being naked and paralyzed, unable to do anything but watch as an alien parasite prepares to burrow itself into your brain.
  • Big Damn Kiss: She lays an epic kiss on Daniel in the pilot, right in front of O'Neill, Carter, and a jeering Kawalsky and Ferretti. Becomes decidedly bittersweet considering what happens next.
  • The Chief's Daughter: Her father is the patriarchal leader of the community on Abydos.
  • Dying as Yourself: After Amaunet is killed, she manages to hang onto consciousness just long enough to tell Daniel that she loves him one last time before following suit.
  • Fan Disservice: In the original cut of the pilot, she was given a full-frontal nude scene in order to mark the show as "adult". Should be fine, since Vaitiare Bandera is a beautiful woman, only it's in the context of Apophis leering at her before she's implanted with a symbiote. This scene was dropped from later cuts of the episode.
  • Fighting from the Inside: She's never able to fully suppress Amaunet's personality, but there are a few occasions where she's shown to be fighting against it. Notably, Amaunet looks directly at Daniel while he's hiding at the end of "Secrets", but doesn't give him up to Apophis. It's left ambiguous whether this is due to Sha're's influence.
  • Last Request: She uses her final moments to send a message to Daniel through Amaunet's hand device asking him to find her son and to forgive Teal'c for killing her.
  • The Lost Lenore: For Daniel. It's implied that he never really gets over her, and her death continues to have a lasting impact on his character for long after her final appearance in the show.
  • Mundane Object Amazement: After her death, Daniel tells a rather poignant story about how she was amazed the first time she saw him using a pen, believing it to be magic.
  • Perfectly Arranged Marriage: A close variant: she was initially sent by Kasuf to offer herself Daniel on Abydos as a gesture of Sacred Hospitality, but Daniel did his best to decline the offer without offending her father. They fall in love for real later.
  • Rape as Drama: She's raped by Apophis while a host to Amaunet, causing her to fall pregnant with the Harcesis. She's shown to be very ashamed by this, and worried that Daniel won't love her anymore. Daniel, of course, comforts her, insisting that he still loves her and only hates what was done to her.
  • Sacrificial Lion: Her death marks the second time an important character is killed on the show (after Kawalsky) and brings an end both to Daniel's personal quest to save her and a to a subplot that was established in the first episode.
  • Shoot the Dog: Teal'c kills her in order to stop Amaunet from killing Daniel, something that she seems to anticipate and be at peace with. He's very sorry about having to do so, but admits he would do it again if faced with the same choice.
  • Star-Crossed Lovers: Every time it looks like she and Daniel might be reunited, they're torn apart again. Reaches its depressing conclusion in "Forever in a Day".
  • Sudden Sequel Death Syndrome: A weird variation. She doesn't actually die until halfway through season 3, but she's kidnapped and turned into a host in the pilot episode after surviving the movie as a fairly major character, and only shows up sporadically from then.
  • You Got Spunk: Part of the reason Apophis picks her as a host. When she struggles against the guards and states that she isn't afraid after being brought before him, he approvingly notes that "this one has spirit".

Played By: Alexis Cruz
First Appearance: Stargate (1994)

Sha're's younger brother and Daniel's brother-in-law, and one of two movie characters who retained their original actors. He was kidnapped from Abydos by Apophis for use as a host for his son Klorel. Much later, after he was captured by the Tollans, O'Neill and Daniel successfully argued in Tollan court for the removal of Klorel. He was mortally wounded by Anubis's troops during the attack on Abydos, but Oma Desala helped him and the other Abydonians Ascend to a Higher Plane of Existence.


  • Death Is Cheap: O'Neill shoots him to stop Klorel from frying Daniel's brain in the first season finale, but he soon returns as Klorel's Jaffa simply put him in the sarcophagus and bring him back.
  • Fate Worse than Death: He explicitly describes being a host as this when he's put on trial in "Pretense" to decide who should be given ownership of his body, which is what ultimately sways Lya to vote in his favor.
  • Fighting from the Inside: Has enough Heroic Willpower to delay Klorel's actions, though it's not enough to stop him entirely.
  • "I Know You're in There Somewhere" Fight: O'Neill encourages him to fight Klorel for control of his body in the first season finale.
  • Last Stand: Takes up arms along with all the able-bodied men in his village when Anubis sends his forces to Abydos at the end of season 6, even though it's pretty much pointless.
  • Like a Son to Me: As a holdover from the movie, it's heavily implied that O'Neill views him as a surrogate son as a result of Charlie's death, though Skaara is quite a bit older than Charlie would have been.
  • My God, What Have I Done?: Feels like this for actions that were actually done by Klorel.
  • Wild Hair: Always wears his hear in unruly dreadlocks.

Played By: Erick Avari
First Appearance: Stargate (1994)

Father of Sha're and Skaara and father-in-law to Daniel, and the other character to keep the same actor from the movie. As the chief of the Abydos community, Kasuf was stern and somewhat old-fashioned in his views but fundamentally a good guy.


  • Parental Substitute: Downplayed, but he seems to be this for Daniel. They address each other as "Good Father" and "Good Son" and appear to get along well enough, even after Sha're's abduction and death.
  • The Patriarch: Both of the Abydos community and towards his children.
  • Politically Incorrect Hero: He's a decent guy, but he's also the product of a very different culture where women are still the property of their fathers and husbands, and has some rather antiquated views on gender as a result. At one point Daniel gets exasperated with him for practically ordering Sha're around and snaps that he can't just tell her what to do, to which Kasuf just gives him a bewildered look and replies that he's her father. Also a case of Deliberate Values Dissonance: this isn't that uncommon among offworld cultures in the show since Goa'uld have a tendency to steal beautiful women as hosts for their queens, so the males in the culture tend to be overprotective.
  • Tastes Like Friendship: Daniel befriends him in the original movie by giving him a candy bar.
  • What Happened to the Mouse?: His last appearance is in season 4, so it's not entirely clear what becomes of him when Anubis destroys Abydos and Oma ascends the entire population.

The Tollan

    In General 

The first real offworld allies made by the team, though they were often more trouble than they were worth. A race of Human Aliens with very strict rules about not sharing their advanced technology with more "primitive" worlds, which frequently annoyed both O'Neill and Hammond. Eventually had an entire planet's worth of bridges dropped on them after their government sold them out to the Goa'uld.


  • Alien Non-Interference Clause: Firmly refuse to share any of their technology with less advanced races, even technology that doesn't have any military purpose.
  • Dropped a Bridge on Him: It's implied their entire race is wiped out at the end of their final episode when Tanith begins an Orbital Bombardment of the planet.
  • Early Installment Weirdness: Carter states at one point that their technology is too advanced for Earth scientists to reverse-engineer, despite the fact that they're just humans who are at most a hundred years ahead of Earth and later seasons have the Tau'ri reverse-engineering technology from completely different species. That said, this was before the Tau'ri had that level of understanding of alien technology, being unaware of even the Asgard at that stage. The Tollan have thus far been the only race not as old as the Ancients that have created their own stargate (albeit with the help of the Nox). Even compared to other, more advanced races, their technology is hardly simple to figure out.
  • Fatal Flaw: Their over-reliance on their advanced technology turns out to be their undoing, causing them to grow complacent and lose any aptitude for military strategy.
  • Glass Cannon: Their space weapons technology is second only to that of the four Precursors and the Precursor Killers, but they don't seem to bother with anything in the way of defensive technology such as energy shields. A single Tollan ion cannon can one-shot a Goa'uld Ha'tak mothership, but during Klorel's trial on Tollana a single bog-standard mothership was able to wipe out their entire defensive grid in a few seconds simply by a) having a legitimate pretext to be in orbit so they wouldn't be shot down instantly, and b) having a spotter on the ground telling them where to shoot.
  • Government Conspiracy: In their final episode it's revealed that their ruling council made a deal with the Goa'uld Tanith to build superweapons for him to use against other planets in exchange for leaving Tollana alone.
  • Higher-Tech Species: Technically they're human, but they fit the trope. They have wearable tech that lets them walk through walls and transmit messages across the galaxy, as well as weapon scanners capable of selectively disabling weapons other than their own Frickin' Laser Beams, and of course surface-to-space artillery capable of one-shotting a Ha'tak-class mothership until Anubis upgraded them.
  • In Your Nature to Destroy Yourselves: Their view of less advanced races after a Noodle Incident in their backstory where sharing their technology with neighboring planet triggered an apocalyptic world war.
  • Sacrificial Lion: They were Earth's most technologically advanced ally other than the Asgard (not counting the Nox, who just wanted to be left alone), so wiping them out effortlessly cement's Anubis' place as a force to be reckoned with.
  • Technical Pacifist: Pride themselves on not being a "war-faring people", but they possess weapons technology capable of obliterating pretty much anybody who dares to attack them (at least initially...) and they definitely aren't afraid of using it if they have to. Unfortunately, as Teal'c observes in "Pretense", they've become reliant on their technology and have lost some of their strategic thinking, which ultimately destroys them.
  • What We Now Know to Be True: At one point Narim claims that the Tollan have studied quantum physics, "among other misconceptions of elementary science".
  • You Are Not Ready: The reason they won't share their technology with Earth.

Played By: Garwin Sanford
First Appearance: "Enigma"

A soft-spoken Tollan who was consistently the most friendly towards the team, though he still viewed them as "primitive". Had a crush on Sam which never really went anywhere.


  • Dogged Nice Guy: Towards Sam, though it starts to border on Stalker with a Crush territory when it's revealed that he uses a recording of her voice for the personal security system in his home.
  • Emotions Versus Stoicism: In the Tollan's introductory episode, when his curiosity about Earth and romantic interest in Sam are contrasted with the very stoic Omoc.
  • I Choose to Stay: He chooses to stay and fight when Tollana is attacked rather than return to Earth with the team.
  • Killed Offscreen: His likely fate at the end of "Between Two Fires".
  • Lost in Transmission: His last radio message to the SGC as Tollana is being blasted from space, with cuts out halfway through.
  • Sadistic Choice: Freezes up momentarily when faced with a choice between allowing Tanith to send a bomb to Earth, or sabotaging the plan and dooming his own people. He eventually chooses the latter.
  • Temporary Love Interest: The first of many men to become entangled with Sam and later fall victim to the Cartwright Curse.

Played By: Tobin Bell
Appears In: "Enigma"

The original leader of the Tollan refugees who came to Earth, Omoc was incredibly blunt and rude but nevertheless highly principled. Disappeared after his first appearance and was later killed for threatening to expose the Government Conspiracy.


  • Bus Crash: He plays a major role in the first Tollan episode, then doesn't show up at all in any of their subsequent appearances until "Between Two Fires" opens with his funeral.
  • Emotions Versus Stoicism: His stoicism is contrasted with Narim's more open nature.
  • Jerk with a Heart of Gold: He comes across like an asshole, but he has reasons for being cautious about the Tau'ri and he does warm up very slightly towards Daniel after the latter disobeys orders to help his people escape the NID. He's also the only member of the Tollan Curia to object to building weapons of mass destruction for the Goa'uld in order to save their own skin.
    • Narim also mentions that he did genuinely respect the SGC personnel, something corroborated by the fact that they attend his funeral, which Narim explicitly states he would only have wanted those he respected to attend.
  • Killed to Uphold the Masquerade: It's implied he was killed for threatening to expose the conspiracy. The official story is that he died of a heart attack, but Narim claims he was in perfect health.
  • Lonely Funeral: O'Neill comments on this when the team attend his funeral. Narim states that he had few real friends as a result of his attitude and would have only wanted people he respected to attend.
  • Ungrateful Bastard: After the team rescue him and his people from a volcanic explosion and bring them back to Earth, his reaction is to complain about being brought to such a "primitive" planet.

    Chancellor Travell
Played By: Marie Stillin
First Appearance: "Pretense"

High Chancellor of the Tollan Curia. Generally acted stern but fair and appeared to have a certain amount of respect for the team, though she was a staunch defender of the non-interference policy. Later made a deal with Tanith to build superweapons for his mysterious employer in exchange for the safety of Tollana and presumed killed in the ensuing Orbital Bombardment from his fleet.


  • Deal with the Devil: She views her deal with Tanith this way.
  • I Did What I Had to Do: It's clear that she doesn't enjoy helping the Goa'uld attack other planets, but she claims she's only doing what's necessary to protect Tollana.
  • Iron Lady: She keeps a tight leash on her emotions in order to maintain her authority.
  • Killed Offscreen: Presumed to be her fate at the end of "Between Two Fires".
  • Reasonable Authority Figure: Until she jumps off the slippery slope. Despite her strict adherence to the Tollan policy on not sharing technology, she was shown to be reasonable in most other matters and proved to be fair while presiding over Klorel/Skaara's trial.
  • Sadistic Choice: Forced to choose between supplying Tanith with nukes to protect her own people or standing her her principles and leaving her planet open to attack. She chooses the former.

Other Humans

    Cassandra Fraiser
Played By: Katie Stuart, Colleen Rennison
First Appearance: "Singularity"

Cassandra was a young girl and the Sole Survivor of a plague that wiped out the population of her entire planet when the team first found her, and turned out to be a Trojan horse left by the Goa'uld Nirrti to try and send a bomb to Earth. After that crisis was averted, she was adopted by Janet Fraiser, and grew up to be a relatively normal Earth teenager.


  • Bratty Teenage Daughter: Fully grows into this trope by the time she's sixteen, giving her adoptive mother attitude and preferring to spend time with the boy she likes than her family.
  • Cute Mute: She initially doesn't speak at all when the team bring her back to Earth, though this is subverted by the end of her first appearance.
  • Dangerous 16th Birthday: She grows extremely ill on her sixteenth birthday and suddenly starts developing psychic powers that turn out to be at risk of killing her unless the team can find a cure.
  • Happily Adopted: For the most part. She sure can give Janet attitude when she wants to, but it's clear that they love each other anyway.
  • Has Two Mommies: Sam is the first person she bonds with when she comes to Earth and they remain close even after Janet adopts her, which turns into this trope when coupled with the close friendship between Sam and Janet. Really made explicit during Cassie's sixteenth birthday party, with both Sam and Janet insisting they spend time together while Cassie would rather go out with her boyfriend.
  • Honorary True Companion: She doesn't show up too often, but it's clear that the entire team dotes on her.
  • I Just Want to Be Special: She has shades of it when she suddenly develops fancy powers, begging Janet to let the changes happen even though it could kill her.
  • Nightmare Fuel Coloring Book: Her drawings when she first comes to Earth after everyone else on her planet is killed include bleeding stick figure corpses, with a single stick figure standing up in the middle of all the carnage.
  • Parental Abandonment: Poor kid can't catch a break. First of all her parents are killed by a plague that also wipes out everybody else on her entire planet, then her adoptive mother is killed in combat by a stray staff blast seven years later, when she's barely eighteen. Her reaction to Janet's death isn't really touched on, however, apart from a throwaway line about her being a "tough kid".
  • Sensor Character: She has traces of naquadah in her blood as a result of the bomb that was inside her, allowing her to detect the presence of Goa'uld symbiotes. This is what serves to tip the others off when Sam becomes a host to Jolinar.
  • Sole Survivor: Of her planet after Nirrti inflicts a plague upon the rest.
  • Trojan Horse: Nirrti uses her to attempt to smuggle a naquadah bomb to Earth.
  • Troubled Child: Initially. She's a sweet enough kid but obviously disturbed by everything that she's been through. She grows out of it eventually.
  • Touched by Vorlons: She temporarily gains psychic powers after turning sixteen.
  • What Happened to the Mouse?: She disappears after season 5 and is barely mentioned in subsequent seasons, even after Janet's death.
  • Why Am I Ticking?: In her first appearance, when Sam and Janet realize there's a bomb inside her.

    Martin Lloyd
Played By: Willie Garson
First Appearance: "Point of No Return"

An alien deserter who crash-landed on Earth some time ago and was drugged by his fellow aliens into believing that he's an Earthling, causing no small amount of paranoia. After remembering his true identity, he went on to write Wormhole X-Treme! the Show Within a Show based on the exploits of the team that largely served as a vehicle for the SG-1 writers to parody themselves during the milestone episodes.


  • Cassandra Truth: He insists that he's an alien, but nobody believes him on account of the fact that he comes across like a conspiracy theorist loon who happens to be on every medication under the sun. Then they find his spaceship.
  • Conspiracy Theorist: Martin is actually something of a deconstruction, as most of his claims turn out to be true and the reason he knows the truth is because, as an alien, he's part of the conspiracy himself.
  • Going Native: Even after he learns the truth, he passes up the opportunity to go looking for a new home with his fellow aliens because he's having too much fun being the producer of a trashy low-budget sci-fi show.
  • Meta Guy: In the 100th and 200th episodes, where he basically exists to hang a lampshade on everything that can be lampshaded. Including the act of Lampshade Hanging itself.
  • Properly Paranoid: He's extremely paranoid about people watching him and messing with his medication, and he turns out to be right on both counts.
  • Show Within a Show: Wormhole X-Treme!, of which he is the writer/producer.
  • You Can't Go Home Again: At the end of his introductory episode he returns to his home planet, only to discover that it's been completely decimated in the wake of the war with the Goa'uld.

    First Minister Dreylock 
Played By: Gillian Barber
First Appearance: "Shadow Play"

Initially an ambassador of Jonas Quinn's home nation of Kelowna. She tried to get help from Earth against two rival nations, but the Tau'ri refused to get involved in their internal affairs. Anubis' attack on Langara gave Dreylock a new perspective, so she helped form a tenuous alliance with the other nations, and ties with Earth are re-established. After that, she is elected First Minister of Kelowna.


  • Enemy Mine: O'Neill and Carter force her hand into cooperating with Tirania and the Andari Federation when her people need help. The attack from Anubis helped convince her that this was no time to worry about old rivalries.
  • Iron Lady: The way she conducts herself in general heavily implies that she fills this role when she becomes the leader of her country.
  • No Name Given: While the people of Langara seem to follow the tradition of "given name, surname", we never learn what her given name is.
  • Rank Up: Non-military version. Her final appearance reveals that she has moved up from ambassador to First Minister after Anubis' forces executed the previous First Minister.

The Tok'ra

    In General 

An offshoot of the Goa'uld who opposed their species' more typical god complex and Puppeteer Parasite tendencies, they insisted on only taking willing hosts and sharing the body equally. Probably Earth's most significant ally for much of the series, though the relationship was often fraught with tension for various reasons. Eventually revealed to be a Dying Race due to a lack of hosts and the loss of the queen who spawned their entire line.


  • Berserk Button: Calling any of them a "Goa'uld" is sure to piss them off.
  • Body Surf: Since they don't use the sarcophagus, the hosts tend to die before the symbiotes, which then go on to take a new host.
  • Character Tic: When switching between host and symbiote control, a Tok'ra will close their eyes, bow their head, then raise their head and open their eyes to signify control has been passed from symbiote to host or vice versa.
  • Chuck Cunningham Syndrome: They largely disappear from the narrative after the end of season 8, with the fall of the Goa'uld empire and Jacob/Selmak's death. They do make a brief reappearance in the penultimate episode of the series, however, and Continuum reveals that they've been able to come out of hiding and establish a society on their own planet with the Goa'uld no longer posing a threat to them.
  • Dying Race: It's eventually revealed that they have negative population growth as the queen from which they were all spawned has been missing for some time (she's eventually found, but she dies shortly afterwards). The main reason they prefer to use stealth attacks and subterfuge over the more aggressive tactics employed by the Tau'ri is that when a Tok'ra operative dies in the field, there isn't another to replace them. "Cure" underlines this and garners them major sympathy points.
  • Even Bad Men Love Their Mamas: They're not bad, as such, but they can often come off as unfeeling dicks. However, "Cure", Egeria's brief come-back appearance, shows that they were all devoted to their mother - to the point of being willing to sacrifice their lives for her - and Malak is shown as being near to tears when she tells him that she is dying.
  • Fantastic Racism: Shades of it towards both the Tau'ri and the Jaffa, who they tend view as inferior.
  • A God I Am Not: Their opposition to portraying gods is one of their primary differences with their Goa'uld kin. Though it's worth noting their progenitor Egeria was a water nymph in Roman myth.
  • Good Is Not Nice: They're wholly dedicated to the fight against the Goa'uld and they're more than willing to act as The Cavalry when they're called upon (they're rarely exactly happy about it, but they'll do it), but they can be extremely arrogant and haughty and they're not above employing some very dubious tactics, often using their human "allies" as guinea pigs or red shirts.
  • Heroic Host: A Tok'ra host can enjoy the benefits of enhanced strength, knowledge, an extended lifespan and resistance to disease if they're willing to timeshare their body with an alien symbiote.
  • Heroic Sacrifice: A fundamental difference with the Goa'uld is their altruism. If a Tok'ra sees their death as the necessary price to complete a critical mission, they'll pay it. Goa'uld, on the other hand, are ultimately dirty cowards if their life is in danger, or will gladly pay the price... with someone else's life. Especially notable since the Tok'ra are a dying race, so every heroic sacrifice brings their whole race one step closer to extinction, and they're still willing to pay that price when it counts.
  • Insistent Terminology: They're extremely vehement in their insistence that they're not Goa'uld, though technically they're the same species.
  • La Résistance: A largely underground splinter group who oppose the rule of the System Lords. Their name literally translates to "against Ra".
  • My Species Doth Protest Too Much: They are very emphatic that they are not Goa'uld, despite being the same species, as they don't share the sadism, megalomania and general evil that characterises the Goa'uld.
  • No Biological Sex: Martouf explains that the symbiotes themselves don't have a biological sex, though many of them display a preference for a certain gender of host.
  • Not So Different: They're still the same species as the Goa'uld and there are cultural similarities.
    • The Tok'ra still possess the belief of superiority to humans, which is particularly evident in the later seasons. In "Death Knell", Delek is dismissive of Jacob/Selmak while the former is in control, and believes that the Tau'ri's wilful behavior makes them more dangerous than the Goa'uld dominated, complacent humans they usually work with. Taken together, it comes off as the Tok'ra not liking the fact that the Tau'ri are harder to control. O'Neill in particular likes to call them out on this.
    • The Tok'ras' protestations that, unlike the Goa'uld, they never take an unwilling host are not entirely accurate. In their first appearance Jolinar jumps hosts from Rosha to an unnamed villager to Carter without permission, and when Jack is briefly host to a symbiote to heal him of the plague that killed the Ancients, it takes him over to rescue one of Ba'al's servants whom it had befriended while undercover on a previous mission. There are mitigating factors though: Jolinar seems to act in desperation (she was being tracked by an assassin and Rosha and host #2 were killed) and her judgement was clouded somewhat by the trauma of losing her primary host who she'd shared minds with for years (her death has a long term psychological impact on Carter, and they only shared bodies for a day or two at most), and the Tok'ra suspect that Jack's symbiote got a little turned around by Jack's No One Gets Left Behind ethos. Considering that Carter came up with and supports this hypothesis, along with the fact that Jack's downright pathological about it, they may have a point.
  • Really 700 Years Old: Not to the same extent as the Goa'uld due to their avoidance of the sarcophagus, but the hosts can expect to live for roughly twice as long as the average human while the symbiotes can survive for even longer.
  • The Mole: One of their favored tactics is to masquerade as a minor Goa'uld in order to infiltrate the ranks of the System Lords.
  • Sharing a Body: It's interesting to note that the echoing symbiote voice, which the Goa'uld use to induce fear, the Tok'ra use to differentiate between the host and the symbiote.
  • Talking to Themself: The hosts sometimes communicate with their symbiotes in this way.
  • Voice of the Legion: Like the Goa'uld, they can speak in a flanged-bass voice. However, when they do this it's mostly a method of helping others identify that the symbiote is speaking instead of the host, who uses a normal voice.
  • We ARE Struggling Together: In later seasons, as the Tau'ri-Tok'ra-Jaffa alliance begins to fracture more and more. All the parties involved are dedicated to bringing down the Goa'uld, but frequently find it difficult to overlook their differences.


First Appearance: "Cure"

The very first Tok'ra, and unusual even by their standards, founding the Tok'ra movement without the outside input (i.e. a more or less functioning moral compass) that she gave to her children. Presumed dead for centuries, if not millennia, it transpires that she'd been in stasis for centuries, like Isis and Osiris, and after being unearthed by the Pangarans (who were completely unaware of who she was), was used for medical experiments. She eventually gives her life to save the Pangarans.


  • All-Loving Heroine: She gave her life to save the people who'd been torturing her through medical experimentation for over half a century.
  • And I Must Scream: While she wasn't necessarily aware in her stasis jar, the following sixty years of medical experimentation can only have been hellish.
  • Defector from Decadence: The original, defecting from the Goa'uld System Lords millennia ago, founding the Tok'ra, the original organised resistance to Goa'uld rule. She paid a heavy price for it, though.
  • Heel–Face Turn: Millennia ago, when she became a Defector from Decadence and founded the Tok'ra.
  • The High Queen: Both as Ra's Queen (possibly more God Save Us from the Queen! back then), and the Queen of the Tok'ra.
  • Small Role, Big Impact: She only appears in one episode, and is only really active in the last ten minutes of that episode, but in that time she saves tens of thousands of people. Her prior actions also created the Tok'ra, a persistent thorn in the side of the Goa'uld, and a strong if reluctant at times ally of the SGC.
  • So Proud of You: Tells Malek that thanks to Kelma sacrificing herself for her, and letting her host blend with Egeria, she knows everything that the Tok'ra have done, what they have become - and moreover, they are beyond her wildest dreams.

    Jolinar of Malkshur
Played By: Amanda Tapping, Tanya Reid
First Appearance: "In the Line of Duty"

The first Tok'ra the audience was introduced to, Jolinar briefly took possession of Samantha Carter in order to hide from a Goa'uld bounty hunter, only to end up giving her own life to save Sam's. Served as the gateway by which the characters were able to meet the rest of the Tok'ra, as well as leaving Sam with some enhanced abilities thanks to the traces of naquadah in her blood.


  • Eternal Love: She and her host Rosha had this with Martouf/Lantash, the four of them having been in a relationship for a hundred years prior to her death.
  • Good Is Not Nice: She's one of the good guys, but she takes Sam as a host without her consent and is not particularly pleasant to the rest of the team - though considering that she had an assassin on her tail and had lost her primary host, something which Martouf and Selmak both note causes a great deal of grief, this is perhaps unsurprising.
  • Heroic Sacrifice: Ultimately gives her own life to save Sam.
  • Honey Trap: She employs a heroic version while imprisoned in Netu, seducing the Goa'uld Bynarr in order to escape.
  • Posthumous Character: Appears in flashbacks in "Jolinar's Memories", over a season after her death.
  • Samus Is a Girl: In a way. Sam initially refers to her with male pronouns until Martouf corrects her, stating that while the Tok'ra have No Biological Sex, Jolinar identified as female and preferred female hosts.
  • Small Role, Big Impact: Dies in her introductory episode but has a much larger impact on the plot due to the introduction of the Tok'ra and the abilities she leaves Sam with.
  • Sympathetic Adulterer: As seen under Honey Trap.

    Major General Jacob Carter/Selmak
First Appearance: "Secrets"

Jacob Carter was Samantha Carter's father and a major general in the Air Force. When he was dying of cancer, SG-1 brought him to the Tok'ra (rebels opposing the System Lords while being the same species as the Goa'uld) to be blended with the symbiote Selmak. This cemented the alliance between the Tok'ra and the Tau'ri, although Selmak himself eventually grew out of favor among his people due to his ties to Earth. Was killed off anticlimactically in the episode "Threads", for seemingly no reason other than to give his daughter something to angst over for all of one episode.


  • Ace Pilot: The combination of an Air Force general and a centuries-old symbiote with extensive knowledge about Goa'uld spacecraft results in this. In one episode he navigates a cargo ship through a minefield while barely breaking a sweat.
  • Amazingly Embarrassing Parent: Not often, but it happens.
    Sam: Welcome to my life.
  • Back for the Dead: After having been absent for nearly a whole season, he reappears for three-episode arc at the end of season 8, at the end of which he reveals that he's dying.
  • Brutal Honesty: He tends to be pretty blunt, and Selmak's tendency towards this is actually part of what endears her to him when they first meet.
  • Convenient Terminal Illness: The fact that Jacob has terminal cancer when he's introduced makes him a perfect host for Selmak, solidifying the alliance between the Tau'ri and the Tok'ra.
  • Dad the Veteran: His influence as such led in part to the prime universe version of Sam joining the Air Force. It also apparently influenced several alternate versions not to join the Air Force.
  • Danger Deadpan: He's cool as a cucumber at the helm of a teltak, even when doing supremely dangerous things like navigating through a minefield.
  • Determinator: Despite Selmak's failing health meaning that Jacob could still be saved if they separated, both refused to part from each other until their work was finished.
  • Dropped a Bridge on Him: Killed off in season 8's episode "Threads".
  • Four-Star Badass: Jacob is an Air Force two-star just like Hammond was for most of the series, although how becoming Selmak's host interacted with that isn't clear. Assuming he kept the rank afterwards, he was running special ops for the Tok'ra for most of the series as a major general.
  • Grumpy Bear: He's introduced like this, Brutal Honesty and all.
  • Grumpy Old Man: Jacob isn't all that old but he sure can be grumpy sometimes.
  • Honorary True Companion: The team treat him like an extension of the family, though he can only ever stick around for brief periods of time before duty calls him away.
  • Humanity Is Infectious: Or rather, Earth humanity is. Selmak starts to fall out of favor with the High Council because they believe his host is influencing his judgement more than they'd like.
  • Jerk with a Heart of Gold: He came across as a real jerk when he first showed up. He grew out of it pretty quickly though, for the most part, as blending with Selmak made him realise some of his own flaws and his desire to reconnect with his daughter and estranged son. It's implied that Selmak was nagging him about it.
  • Only Sane Man: O'Neill considers him to be this among the rest of the Tok'ra.
  • Parents as People: His relationship with both of his children is initially quite strained due to his putting the military first and the indirect role he played in their mother's death. Despite that, it's clear that he does love them both a great deal, even if his pride sometimes gets in the way of him saying it.
  • Real Award, Fictional Character: His party salad in "Secrets" shows ribbons for, among other things, the Legion of Merit and the Distinguished Flying Cross, two of the highest decorations that may be awarded to a US airman. The Cross probably wasn't earned in combat given the lack of a V device, but the Air Force doesn't authorize the V device for the Legion of Merit.
  • Shipper on Deck: Makes a few comments in "Threads" which seem to indicate he would not be entirely opposed to his daughter getting into a relationship with O'Neill.
    • Interestingly, in a more meta example, Carmen Argenziano stated in an interview that he personally thought that Daniel Jackson would be a good match for Sam.
  • Talking to Themself: "Seth" has an amusing instance of Selmak telling Sam that he's irritated with Jacob not having made up with his son/Sam's brother, immediately followed by Jacob contradicting Selmak.
  • Team Dad: Sometimes takes on this role when he accompanies the team on missions. The fact that he is actually Sam's dad helps.
  • Took a Level in Kindness: Jacob gets a lot nicer after blending with Selmak, though he can still be extremely bad-tempered when he wants to be.
  • What the Hell, Hero?: Frequently calls out the team for some of their more reckless moves and criticizes them for knocking off System Lords left right and center without a thought for the Evil Power Vacuum they're creating in the process.
  • You Are Not Ready: He's of the opinion that the Tau'ri has a tendency to dabble in technology too advanced for them to truly understand. When Sam accuses him of being a hypocrite, he points out just how uniquely positioned he is to realize how far out of their depth they are. Considering that this is the episode where the SGC had tried to use a captured Death Glider without considering potential counter-measures against it, and how often SG-1 and the Tau'ri as a whole accidentally screw things up/make them explode by messing with tech they don't understand, he kind of has a point.

Played By: J.R. Bourne
First Appearance: "The Tok'ra, Part 1

Formerly the mate of Jolinar, he and Sam quickly established a connection, though they were always unsure how much of their feelings were "real" and how much could be attributed to Sam's lingering memories of Jolinar. Generally friendlier than most of the other Tok'ra and seemed to get on well with the whole team. Martouf was killed early in season 4 after being turned into a Manchurian Agent, while his symbiote Lantash managed to live a while longer on life support before performing a Heroic Sacrifice when the Tok'ra base was destroyed.


  • Back for the Dead: Done twice, no less. He first disappears halfway through season 3, then returns for a single episode at the beginning of season 4 that Martouf is killed at the end of. Then in season 5 it's revealed Lantash is still alive, but he dies shortly after taking a critically injured SGC member as a host and being unable to repair the damage, sacrificing himself to save SG-1 and Jacob/Selmak.
  • Crocodile Tears: Pulls this while being tortured on Netu, allowing him to convincingly feed Apophis incorrect information.
  • Died in Your Arms Tonight: In Sam's.
  • Dying Declaration of Love: A weird example where the dying Lantash tells Sam by proxy through Lt. Elliot that he really did come to love her for who she is, not just her memories of Jolinar.
  • Eternal Love: Had this with Jolinar and her host Rosha prior to the events of the series.
  • Heroic Sacrifice: Faced with the knowledge that he and his new host of Lieutenant Elliot aren't going to survive their injuries, Lantash takes a sample of symbiote poison to kill the Jaffa army preventing SG-1 and Jacob/Selmak reaching the Sargate.
  • Manchurian Agent: Gets turned into a zatarc in "Divide and Conquer". He has no idea he's been brainwashed until the trigger event occurs, when he's programmed to start shooting until he kills his target (in his case, the President), and then kill himself.
  • Nice Guy: He's a lot more approachable than many of the other Tok'ra and doesn't seem half as arrogant.
  • Rasputinian Death: After his programming kicks in, the SFs riddle him with with bullets and Teal'c shoots him with a zat, but he's still going strong until Sam zats him a second time, killing Martouf. Lantash manages to survive a while longer before getting caught in a cave-in, taking on a dying host and then killing them both with symbiote poison in a Taking You with Me scenario that happens offscreen.
  • Ship Tease: With Sam, though it's not made entirely clear how much of their bond is left over from Jolinar. Lantash eventually claims via Lt. Elliot that Martouf did come to love her for who she was.

Played By: Vanessa Angel
'''First Appearance: "Upgrades"

A Tok'ra scientist with some seriously dubious ethics and a tendency to use the team as her guinea pigs, as well as being somewhat lacking in social skills. Initially introduced for a three episode arc at the beginning of season 4 to add some sex appeal to the show, only to be unceremoniously dropped when the writers decided the show didn't need sex appeal after all.


  • Cassandra Truth: She claims that she's been trying to warn the Tok'ra about the threat posed by zatarcs for quite some time, but she isn't taken seriously until brainwashed people start freaking out and gunning down everything in sight.
  • Do You Want to Copulate?: Freya propositions O'Neill this way in "Divide and Conquer". When he gets flustered by it, she explains that she comes from a planet where people are much more upfront about sex.
  • For Science!: Her primary motivation, which sometimes causes her to cut corners when it comes to ethical considerations.
  • I Did What I Had to Do: Her justification for allowing Tanith to live so the Tok'ra can use him to Feed the Mole, despite his murder of Shaun'auc at the fact that his unwilling host is still suffering.
    Anise: We are fighting a war for our very existence. I make no apologies for the means.
  • Love Triangle: Gets into a weird version of the trope with herself as Freya likes Jack but Anise prefers Daniel, demonstrating one of the downsides of Sharing a Body. For their part, both Jack and Daniel seem vaguely disturbed by the entire thing.
  • Meaningful Name: "Freya" is also the Norse goddess of love, beauty, and sexuality. Not only is Anise/Freya Ms. Fanservice, but the Norse name puts her in direct counterpoint to the Goa'uld, as Norse names are the province of their greatest enemies, the Asgard.
  • Ms. Fanservice: Her outfits always show off a lot of skin, which seems particularly egregious considering the plain, functional clothes worn by all the other Tok'ra, including the other females.
  • No Social Skills: Sometimes. In addition to her rather forward attitude to sex, she can be quite blunt and doesn't seem to notice the fact that the team find her annoying.
  • Tested on Humans: Has a habit of testing her latest discoveries on the team, including the armbands that gave them all superpowers at the cost of their common sense and her highly experimental zatarc detector. In her defense, she was genuinely trying to help in the second instance and the technology does prove useful again in later episodes.
  • What Happened to the Mouse?: Has a fairly major role for three episodes at the beginning of season 4, then disappears with barely a mention. It's unknown whether she survived the destruction of the Tok'ra base the following season.

The Free Jaffa

    In General 

A race of super-strong warriors engineered and indoctrinated by the Goa'uld. The Jaffa rebellion gradually gained traction as the series progressed, and by the end of season 8 most of the Jaffa were free, though there were still a few serving Ba'al. As with the Tok'ra, their alliance with the Tau'ri was often challenged by political and cultural differences.


  • And Then What?: Once the rebellion actually succeeds, it becomes clear that the Jaffa never really had much of a plan in place as to what they should do next, and their new government accordingly runs into some problems. Such as how to actually govern, and what to base representation in government upon.
  • Government Drug Enforcement: The Jaffa have been genetically engineered so that their entire immune system is dependent on a larval Goa'uld symbiote that gets implanted into a pouch in their abdomens when they come of age. This causes a few logistics problems for the rebellion since it means they're dependent on the Goa'uld to survive, at least until the introduction of the replacement drug tretonin in season 6.
  • I Die Free: What you can expect any of them to say when faced with their imminent demise.
  • Heel–Race Turn: Never really evil so much as heavily indoctrinated and Just Following Orders, but in the early seasons most of the Jaffa we see are Mooks trying to kill SG-1 on the orders of their "gods". More and more of them join the rebellion as the series progresses, and by the final seasons the newly-established Free Jaffa Nation is one of Earth's major allies.
  • Honour Before Reason: As a rule, they will do what they believe is right over what might be convenient.
  • Proud Warrior Race: They place a great deal of importance on fighting with honor.
  • Really 700 Years Old: The Jaffa lifespan is much longer than that of a human, though it's never made entirely clear just how old they can live to be. Bra'tac is a spritely 133 when we first meet him, while after the events of the season finale Teal'c is over 150 and still going strong.
  • Slave Brand: They all have the mark of the Goa'uld they once served tattooed upon their foreheads. The First Primes (highest Jaffa rank, second only to their masters) had this taken a step further by having the tattoo designs gouged out of their forehead, and molten gold poured into the wound.
  • Slave Race: They were initially created for the explicit purpose of serving the Goa'uld.
  • Super Soldier: The Jaffa were engineered to be much stronger and faster than the average human, and are trained in combat from an early age to create formidable armies for their masters.
  • We ARE Struggling Together: Their relationship with both the Tau'ri and the Tok'ra becomes increasingly fraught due to their opposing ideologies, despite the fact that they're all allied against the Goa'uld. It more or less holds until the Goa'uld are defeated (it helps that Teal'c, the first major Jaffa rebel and a Living Legend as a result, and Bra'tac, who's even more of a Living Legend, are pro-Tau'ri and two of the most prominent members of the Jaffa Rebellion), but just barely. After, the strain grows greater when facing down the Ori.

Played By: Tony Amendola
First Appearance: "Bloodlines"

Teal'c's former teacher and his predecessor (and as The Mole, temporary successor) as Apophis's First Prime. One of the leading Jaffa rebels, who guided Teal'c to the realisation that the Goa'uld were not gods, he's a key to the SGC's successes both on and offscreen. Has a habit of not dying.


  • Ace Pilot: Whether with a Death Glider or an Al'kesh, Bra'tac is good behind the stick.
  • Cool Old Guy: Very much. This is the guy who even the entirely irreverent O'Neill defers to and insists on others referring to him as Master Bra'tac.
  • Death Glare: Excellent at this, for almost any occasion. Ties in with Living Lie Detector.
  • Determinator: He survives things that push even Teal'c to his limits.
  • The Good Chancellor: He was this to Apophis before rebelling, trying to at least restrain and mitigate his boss's evil.
    Bra'tac: His will can be made to bend. But not always.
  • Good Is Not Nice: He can be harsh and blunt when he feels the need, especially in his first appearance when he is not especially impressed by the Tau'ri - though that was at least partly to spark a reaction.
  • Hidden Depths: He reveals a surprising spiritual side when he accompanies the team to the holy temple at Kheb in "Maternal Instinct". Besides Daniel, he's the most open to the teachings of the monk, and he displays an interest in ascension.
  • Honorary True Companion: Initially just a friend of Teal'c's, he becomes close to the entire team over time. He seems particularly fond of O'Neill, and has a vast amount of respect for "Hammond of Texas".
  • I Need a Freaking Drink: After the first disastrous attempt at marrying Rya'c and Kar'yn — there is a sticking point over the equivalent of honour and obey — Bra'tac sighs and downs the cup of ceremonial wine, muttering that he now sees why humans typically rehearse such ceremonies.
  • The Leader: To the Jaffa rebellion to begin with, since Teal'c's off fighting the Goa'uld with the Tau'ri, and falls into the Charismatic category. This is the guy who's made his life's work out of talking people out of believing in their gods, in a society where such a thing is blasphemy and could easily get him killed. He routinely gets Jack O'Neill, the definitive Military Maverick, to shut up and follow his lead with a mere couple of words. And during Teal'c's forceful deprogramming, he talks Doctor Frasier out of opposing the method with less than a dozen words. In other words: this guy is good.
  • Like a Son to Me: He acts as a surrogate father figure to Teal'c throughout the entire series, and tells him in his final episode that he considers him to be the son he never had. Correspondingly, he treats Rya'c like his own grandson.
  • Living Lie Detector: By staring directly and closely into a person's eyes, he is able to tell almost without fail if they are lying. He can even do this if the character has been brainwashed into lying. However, the almost is important, as it didn't help him much in "The Warrior", where he fell completely for Imhotep's lies - a rare case where he picked up the Idiot Ball.
  • Mentor Archetype: For Teal'c in his backstory, and later for Rya'c.
  • Mentor Occupational Hazard: Once or twice it looks like he'll suffer this, but the simple fact is that he's too awesome to die.
  • Mook–Face Turn: Actually, it's later revealed that he was working against Apophis long before the events of the series, and planting seeds of doubt in Teal'c from the get-go.
  • Old Master: Fittingly enough, Teal'c addresses him as "Master Bra'tac." And so does almost everyone else, including Jaffa serving other Goa'uld, and even General Hammond. When Kinsey casually calls him "Mister Bra'tac," O'Neill's quick to correct him: "It's Master Bra'tac." It can be assumed that, rather than actually referring to a teaching rank, it is actually an honorary title given to Bra'tac out of respect for his wisdom and honor. It gets to the point that he actually officiates Rya'c's wedding.
  • Politically Incorrect Hero: In his early appearances he makes a few vaguely sexist comments about Carter, probably because the Jaffa on Chulak don't tend to involve their women in combat - though that might be because he was trying to get a rise out of SG1 and see what they were made of. Either way, it diminishes before long, probably after he noticed that she kicked at least as much ass as everyone else, if not more, and he later upbraids Rya'c for not taking his bride seriously as a fellow warrior.
  • Proud Warrior Race Guy: And trainer of many others. He takes honour and prowess as a warrior very seriously indeed.
  • Really 700 Years Old: He's 133 when we first meet him.
  • Running Gag: Addressing Hammond as "Hammond of Texas"; this even continued when O'Neill replaced him as the SGC commander, with Bra'tac addressing him as "O'Neill of Minnesota." Though he seems aware the latter does not have the same ring.
  • Scarily Competent Tracker: In "Maternal Instinct", not only does he give a very detailed explanation of what the group he was tracking was doing, but he also explains exactly what tips him off to each detail.
  • Screw Politeness, I'm a Senior!: Not as much as most cases, but he will not hesitate to call someone out hard if he thinks that it needs doing, and he'll be pretty blunt in how he does it.
  • They Call Me Master Bra'tac: Not done by himself, but in one scene Kinsey casually addresses him as "Mister Bra'tac", only for O'Neill of all people to correct him that it is "Master Bra'tac. Master."
  • Warrior Poet: Like Teal'c, he's a greatly respected leader and revered teacher among the Jaffa, in addition to kicking plenty of ass.
  • Your Eyes Can Deceive You: His look-them-in-the-eyes method of lie detection is usually infallible. As Imhotep proved, however, 'usually' is not 'invariably'.

Played By: Neil Denis
First Appearance: "Bloodlines"

Teal'c's son. Initially just a Tagalong Kid but gradually grew into a courageous young man as the series progressed and he received training from Bra'tac.


  • Ace Pilot: He definitely takes after his father in this respect, as he gets to show off in "Redemption, Part 2" by outmaneuvering Anubis's forces in a stolen Death Glider.
  • Battle Couple: He eventually marries Kar'yn, a young female Jaffa from the Hak'tyl and this trope is lampshaded, though we never actually see them in battle together.
    Bra'tac: May you love and fight like warriors... just not with each other.
  • Brainwashed and Crazy: He gets brainwashed by Apophis as part of a plot to destroy Earth in season 2.
  • Calling the Old Man Out: Frequently does this to Teal'c, reminding him that his family is struggling without him while he's out fighting a war.
  • Coming-of-Age Story: He starts out as little more than a kid on the verge of adolescence, but matures tremendously over the course of the series.
  • I Just Want to Be Badass: Most notably in the season 6 premiere, when he insists on accompanying Teal'c and Bra'tac for a dangerous and important mission despite the fact he's never been out in the field before.
  • Took a Level in Badass: After a few years of training from Bra'tac, who goes from a Tagalong Kid to a genuine warrior in his own right.
  • What Happened to the Mouse?: The last we see of him is at his wedding and he's scarcely mentioned afterwards, so we never find out what he's up to after the rebellion succeeds.

Played By: Salli Richardson-Whitfield, Brook Parker
First Appearance: "Bloodlines"

Teal'c's wife and mother of Rya'c. Her relationship with her husband was often strained, though they loved each other a great deal. Died unexpectedly at the beginning of season 6.


  • Bus Crash: She dies offscreen after a long absence in the season 6 premiere.
  • Mama Bear: She makes it clear that her son comes first, and she will do just about anything to protect him. Her first appearance has her attacking Teal'c when she thinks he might cause harm to Rya'c.
  • The Other Darrin: The actress who played her in her first episode was replaced for all of her subsequent appearances.
  • Sympathetic Adulterer: She starts a relationship with and later marries Fro'tac, another Jaffa, while still married to Teal'c, but the marriage is purely one of convenience to provide a better life for Rya'c after they were sent to the slums following Teal'c's desertion.
  • Viking Funeral: Teal'c burns her body on a pyre after she dies.
  • What the Hell, Hero?: Has a habit of calling Teal'c over the fact that he essentially abandoned his family, even if it was for a good cause.

Played By: Musetta Vander
First Appearance: "Crossroads"

Formerly a High Priestess in the service of Apophis, and an old lover of Teal'c's. She made contact with the team in season 4, claiming to have successfully communicated with the symbiote inside her and taught it to defect to the Tok'ra. Unfortunately, that symbiote turned out to be Tanith, who promptly killed her as soon as he got a body of his own.


  • And You Were There: She reappears as Teal'c's "wife" during his Cuckoo Nest dream when he imagines himself as an ordinary human firefighter while on the brink of death in "The Changeling".
  • High Priestess: She was a High Priestess in Apophis's court.
  • Killed Offscreen: We only see Tanith attack her, and then her body being brought back to Earth.
  • The Lost Lenore: For Teal'c. Weirdly, her death seems to affect him more than that of his actual wife, and sparks a long-running vendetta against Tanith that gets the team into hot water on more than one occasion.
    • The effect it has on Teal'c might possibly be because Drey'auc died of more or less natural causes, while Shaun'auc was murdered in cold-blood and in the most hideously painful fashion possible, with her murderer got off scot-free (initially).
  • New Old Flame: Again, for Teal'c.

Played By: Obi Nedfo
First Appearance: "The Serpent's Venom"

Originally The Mole who sold Teal'c out to Heru'ur, but watching Teal'c stand by his principle in the face of extreme torture inspired him to join the rebellion for real and he became one of Teal'c's strongest supporters for the remainder of the series.


  • Badass Beard: He has a beard and acquits himself quite well in combat.
  • Facial Horror: The mark of Apophis on his forehead was burned off by his father, leaving a mass of scar tissue in its place.
  • Heel–Face Turn: He joins the rebellion for good after being inspired by Teal'c's refusal to give in, killing Teal'c's torturer and helping him to escape.
  • The Mole: Initially infiltrates a meeting of the Jaffa rebels in order to betray Teal'c.
  • Undying Loyalty: To Teal'c, following his Heel–Face Turn.
  • You Killed My Father: A weird example. He initially holds Teal'c responsible for the death of his father despite the fact that Teal'c once spared his life, as he was later executed by Apophis for following Teal'c's example and rebelling.

Played By: Jolene Blalock
First Appearance: "Birthright"

The leader of the Hak'tyl, an all-female tribe of rebel Jaffa from the domain of the Goa'uld Moloc. Had a turbulent, on-again-off-again relationship with Teal'c and clashed with him over his sometimes old-fashioned views on gender.


  • Action Girl: Holds her own in hand-to-hand combat against Teal'c.
  • Amazon Brigade: She's the leader of one.
  • Asskicking Equals Authority: When one of her followers decides to challenge her authority, she keeps her position by kicking the challenger's ass in combat.
  • Badass in Distress: Gets captured and tortured by Moloc in her second appearance.
  • Belligerent Sexual Tension: With Teal'c.
  • Don't You Dare Pity Me!: She doesn't particularly appreciate Teal'c showing her pity when she begins to weaken from going too long without tretonin.
  • The Leader: Of the Hak'tyl.
  • I Did What I Had to Do: Her justification for killing enemy Jaffa and taking their symbiotes, as the young Jaffa girls under her care would die without them.
  • My God, What Have I Done?: She realizes she's inadvertently killed a free Jaffa, causing her to wonder how many other potential allies she's killed over the years.
  • What Happened to the Mouse?: Never seen or mentioned after her second appearance, despite her relationship with Teal'c.
  • What the Hell, Hero?: She lays into Teal'c for overlooking the plight of the female Jaffa in his focus on the bigger picture.

Played By: Louis Gossett Jr.
First Appearance: 'Origin'

The first leader of the newly-formed Jaffa Council following the rebellion, Gerak was a tyrant and fundamentalist who clung to the old ways. He converted to Origin and was briefly turned into a Prior before seeing the error of his ways and pulling a Heel–Face Turn that caused him to spontaneously combust.


  • Asskicking Equals Authority: During the formation of the Free Jaffa Nation he pushes a plan to award representation according to army size, which probably not coincidentally means he ends up as ruler.
  • Bald, Black Leader Guy: He's elected as the leader of the Free Jaffa Nation at the beginning of season 9.
  • Face–Heel Turn: He was never exactly pleasant, but he doesn't become a true antagonist until he embraces Origin and starts urging the other Jaffa to convert or die.
  • Heel–Face Door-Slam: After Teal'c talks some sense into him he tries to make amends by curing the victims of the Ori plague, only to get set on fire for his troubles due to a failsafe inbuilt in the makeup of the Priors.
  • I Die Free: His Famous Last Words:
    Gerak: If I help you, I will die. But I! Will Die! Free!!
  • Kill Me Now, or Forever Stay Your Hand: Teal'c pulls this on him in order to get through to the part of him that hasn't been corrupted by the Ori.
  • Touched by Vorlons: Gains a few psychic powers after being being turned into a Prior.

     The Sodan
First Appearance: "Babylon"

A near-legendary group of Jaffa who first abandoned the Goa'uld centuries ago and have been living in solitude ever since. Their relationship with the team got off to a bad start after it looked like Mitchell had killed one of their own, but he eventually earned their respect. Got wiped out by a Prior towards the end of season 9.


  • Attack Hello: Have a tendency to do this due to their cloaking technology.
  • Category Traitor: They view the other Jaffa as this for staying subservient to the Goa'uld for so long.
  • Dropped a Bridge on Him: Their entire community save for Haikon gets killed off in an episode that's otherwise filler when a Prior decides to exact revenge on them for rejecting Origin.
  • Invisibility Cloak: They use armbands which seem to work in a similar way to phase-shifting technology in order to render themselves invisible and get the drop on their opponents. The technology is later adopted by the SGC.
  • Killed Offscreen: Jolan, who had a large role in their introductory episode and befriended Mitchell.
  • Never Hurt an Innocent: Their reason for rejecting Origin after initially being tempted by its promises is that a Prior instructed them to wipe out a world of "unbelievers" who turned out to be simple farmers.
    Haikon: The Sodan are proud warriors. We do not kill innocent people.
  • Odd Friendship: Mitchell becomes good friends with Jolan after the latter spends weeks training him in the Soda fighting style, despite the fact that Jolan spends much of that time believing Mitchell killed his brother.
  • Proud Warrior Race: To an even greater extent than the regular Jaffa.
  • Shrouded in Myth: They're extremely reclusive and a few members of the team express doubts as to whether or not they actually exist prior to meeting them.
  • Sole Survivor: Haikon is the only one to survive after they're "cursed" by the Prior.
  • What Happened to the Mouse?: ...However, it's never made entirely clear what becomes of him following the attack.
  • Worthy Opponent: Jolan and to some extent his brother Volnek eventually come to consider Mitchell this.

The Asgard

    In General 

A highly advanced, benevolent species of The Greys, who posed as a god to Norse-inspired human diaspora cultures. Despite — or likely, because of — their superior technology, they displayed a lack of ability to think outside of the box when it came to military strategy, and would often turn to the team for creatively simple solutions for dealing with their enemies. They were also generally more willing to share their technology than the other advanced races, culminating in their decision to give "everything they have and know" to the Tau'ri before committing mass suicide in the series finale.


  • Alien Non-Interference Clause: The Protected Planets Treaty between the Asgard and the Goa'uld designates a number of planets as off-limits to the Goa'uld, but the Asgard also are barred from letting the local humans advance beyond the Iron Age (which causes serious problems when the Asgard try to add Information Age Earth to the treaty). The Asgard agreed to this not because they have any fondness for the Goa'uld, but because their war with the Replicators is tying up the resources they would otherwise use to clear them out altogether.
  • Anonymous Benefactor: The Asgard usually let their work speak for itself.
  • Benevolent Precursors: Unlike the neglectful Ancients and abusive Goa'uld and Wraith, the Asgard carefully shepherd those humans of the galaxy who are under their protection, and would happily steamroll the Goa'uld for them were it not for the Replicators tying up their fleet. They take a liking to the Tau'ri in particular and guide them to take up the Asgards' mantle as their species slowly dies out.
  • Big Good: There is no other race in several galaxies as universally kind and helpful as them. While the humans of the SGC share those moral virtues, they certainly don't represent all of humanity.
  • Cloning Blues: Millennia of cloning themselves has degraded their DNA quite severely.
  • Deus Exit Machina: On several occasions, they're not available because of their battles against the Replicators. Then they die.
  • Ditto Aliens: Justified due to their use of cloning technology, though O'Neill still catches himself at one point before saying they all look the same.
  • Dying Race: Revealed to be this about halfway through the series, as their cloning process turns out to be unsustainable and they're no longer capable of sexual reproduction.
  • The Greys: Roswell Greys to be exact.
  • Faster-Than-Light Travel: They have the fastest kind in the show, clocked by fans at about 150 light years per hour in later seasons, and indeed among the fastest in all of science fiction. At full speed they can travel between galaxies in a matter of a few hours. This is not only millions of times faster than what the Goa'uld have it is significantly faster Ori warships. The thing known to be faster is Atlantis with its full complement of ZP Ms for power.
  • Higher-Tech Species: They start out as awe-inspiringly advanced, ship-for-ship far superior to any Goa'uld military force. And only get more impressive as the show goes on.
  • The Man Behind the Curtain: They take on the identities of the Norse gods and appear to the less-advanced civilizations under their protection as the typical muscular Vikings in armor - that said, unlike the Goa'uld, they explicitly arrange for the day when each civilisation under their protection has advanced far enough. Naturally, it comes as quite a shock the first time one of the civilizations in question gets to peek behind the curtain and realizes that their "gods" are actually a race of frail, diminutive grey aliens.
  • Muggles Do It Better: They often turn to the team for help in their war against the Replicators, which are immune to their advanced technology but can be harmed by kinetic weapons. Generally, their biggest flaw is the fact that they've lost the capacity to think creatively in the same way that humans can, something they're very much aware of.
  • Nice Job Breaking It, Hero!: Part of the reason the Replicators are as formidable as they are is that the Asgard decided to capture one for study, assuming their technology would protect them. Instead, it was able to learn from that same technology and replicate, creating a swarm of nigh-indestructible techno-bugs based on some of the most advanced materials in the galaxy.
  • Not So Different: One episode makes the point that while their intentions may be a good deal more honorable than that of the Goa'uld, they're still posing as gods to people that don't know any better and hindering their progress. Generally downplayed, however, as they are willing to share their technology with other races once they're sure that they can handle the responsibility, arranging tests that once passed lead to more direct contact with the Asgard themselves. The whole God Guise thing is more a matter of convenience than anything else.
  • Proud Scholar Race: Their focus on science and technology is very much at the heart of their civilization, something that eventually leads to their downfall.
  • Running Gag: They (mostly Thor) have a habit of beaming people up whenever they're in the middle of a conversation or just generally at the most inopportune moment. Amusingly, this habit carries over once the humans get beaming technology of their own.
  • Story-Breaker Power: Being at constant war with the Replicators while also being a dying race must be the writers' ways of keeping them from solving every major conflict in the Milky Way. Because if they could, they would (and in one alternate universe, they did).
  • Suicide Pact: They commit mass suicide in the series finale after their Clone Degeneration leaves them with an incurable disease, so as to prevent other species scavenging their tech.
  • You Are Not Ready: This is initially their stance towards the Tau'ri, but they gradually subvert it over the course of the series, sharing more and more of their technology with the team before ultimately leaving them everything they have in the final episode.

Voiced By: Michael Shanks
First Appearance: "Thor's Chariot"

Supreme Commander of the Asgard Fleet, and largely the most helpful and friendly of his people. Had a huge soft spot for the team in general and O'Neill in particular.


  • Accidental Hug: Carter gave him one once, he didn't mind though.
  • Back for the Finale: He reappears in the final episode after a three season absence. Unfortunately, it's also a case of Back for the Dead, as he shows up predominantly to announce that the Asgard intend to kill themselves en masse.
  • Big Good: Thor is a hero in just about every sense of the word and the Supreme Commander of the Asgard. He even helps Hammond keep his position in SGC.
  • Big Damn Heroes: In "Thor's Chariot", he has the Beliskner descend over Cimmeria, promptly begin beaming away all the Goa'uld forces including their pyramid-ships, then simply turns around and leaves.
  • Blunt Metaphors Trauma: Occasionally falls victim to this.
    O'Neill: I full well expected the other shoe to drop eventually.
    Thor: We can only hope that this will be the last footwear to fall.
  • Deadpan Snarker: Very sarcastic when he wants to be. Many Asgard end up being this way, but perhaps especially Hermiod, the Daedalus' Asgard crewmember on Stargate Atlantis.
  • Fanboy: The majority of the Asgard hold Humanity in a quite positive regard, but Thor can only be called a fanboy of humanity. The guy names two of his ships after members of SG-1!
  • The Gadfly: Nevertheless, has a very evident sense of humor, and sometimes has fun at SG-1's and Stargate Command's expense. Perhaps especially when he offers Carter Asgard food, and tells her he likes the yellow ones. And when he beams half the food out of Stargate Command without having refrigerators, forcing SG-1 to chow down on ice cream and other perishables. Not to say they really mind. More generally, when he beams people and/or things out of the SGC unilaterally, causing hilarity to ensue in ways that are just too specific not to have been Thor's intent, at least to some degree.
  • Hidden Depths: Thor comes across as a fairly generic stoic Big Good, but a few scenes show there's much more to the stoic little alien. When explaining to Politicians the Asgard's support of Hammond's leadership, he explains that their friendship with humanity does not hinge on Hammond's keeping command of SGC, but immediately appends that with "But it is preferred" and says that last part in a low, almost threatening tone. Making it clear that the Asgards' stance with humanity as a whole will not change, Thor would take Hammond being removed from command as a personal slight - and as he remind Kinsey, he IS the Supreme Commander of the Asgard.
  • Interspecies Friendship: With all of SG-1 and Hammond. Mostly O'Neill, cause they're best buds. The guy even offered to take Thor fishing for crying out loud!
  • Killed Offscreen: In "Unending", when the entire Asgard planet blows up.
  • The Man Behind the Curtain: Initially appears as holograms of classical Viking Thor, before revealing himself in the Hall of Thor's Might.
  • Odd Friendship: His weird little relationship with O'Neill. You wouldn't think that an irreverent Air Force colonel and a stoic little grey alien would have all that much in common, but they get along like a house on fire.
  • Straight Man: Usually to Jack O'Neill's Wise Guy.
  • The Stoic: For a cute little Roswell Grey, he's very stoic.
  • They Call Me MISTER Tibbs!: In an episode. Senator Kinsey keeps calling him "Commander" as Thor just dropped in on a multinational summit to decide the fate of the SGC, to give a rather impressive bit of support for General Hammond to the present politicians (Most of whom have never even seen an alien before!). Upon being called "Commander" one too many times he cuts off Kinsey "SUPREME Commander", correcting him and in doing so putting emphasis on how Thor can speak for the entire Asgard race.

Voiced By: Brian Jensen
First Appearance: "Red Sky"

A member of the Asgard High Council, the body that governs the rest of the Asgard. Tended to show up to hear and refuse requests that would break the Protected Planets Treaty.


  • Badass Bureaucrat: He does act like a bureaucrat who leaves no room for interpretation in the law, but he's really just keeping planets under Asgard protection safe from attack by the Goa'uld. He also commands a battleship very well.
  • Big Damn Heroes: Towards the end of "Revelations", he shows up with three Asgard ships to save the team from Anubis. Since it was he who got them in danger to begin with by asking for their help, it's no surprise that he oversees the rescue himself.
  • Killed Offscreen: It can be assumed that this was what has happened to him by the end of the series, given the events of "Unending".
  • Reasonable Authority Figure: He and the rest of the Asgard High Council collectively serve this role to their race.
  • What Happened to the Mouse?: During the fifth season, he was a semi-important character who is never referred to again after the season finale. Presumably he shared the rest of the Asgard's fate in the series finale, but we have no idea what he was doing during the second half of the series.

The Ancients and Ascended Beings

    In General 

The Ancients were a highly advanced race of humans who evolved in another galaxy millions of years ago before ascending and seeding life in the Milky Way. As ascended beings, they had a very strict policy about not interfering in the affairs of mortals, with harsh punishments for any who broke the rules.


  • Alien Non-Interference Clause: They absolutely refuse to intervene in the "lower planes", with few exceptions. They attempt to justify it with the usual arguments about not messing with free will, but once the Ori arrive and start their holy crusade — with plans to come for the Ancients themselves next — it seems there's little excuse for it.
  • All-Powerful Bystander: They have enough power to end just about any conflict if they were allowed to get involved.
  • Ancient Astronauts: They're the original builders of the Stargate network and were out exploring the universe millions of years before humanity in its current form evolved.
    • Millions, as in the oldest known Milky Way style Stargate is over 50 million years old and Destiny was said to be over 60 million years old
  • Broken Pedestal: For Daniel, who practically revered them before realizing that they're just as messed up as humans, and less inclined to try and do the right thing.
  • Doomed Moral Victor: Although it never quite comes to it, the fact that they refused to give up their pact of non-intervention, even in the face of the Ori indicates that they were completely willing to become this.
  • Energy Being: In their ascended form.
  • Figure It Out Yourself: Most of them are of the belief that anyone who's worthy of ascension should be capable of getting there on their own. Oma is the exception who proves the rule, and an outcast because of it.
  • A Form You Are Comfortable With: In their true from they're glowing squid-things made of energy, but they can appear as human if they want to. This also applies to their entire plane of existence; when a freshly-deceased Daniel visits the ascended plane towards the end of season 8, it appears as a diner from one of his childhood memories.
  • If You Kill Him, You Will Be Just Like Him: Or rather, 'if you interfere'. The reason they maintain their non-intervention against the Ori is that they believe that if they break their pact, they will be no better than the Ori themselves.
  • Neglectful Precursors: Given the fact that they created life in the Milky Way but refuse to get involved with it. Becomes a little muddier in season 9 with the reveal that they were deliberately keeping the Milky Way hidden from the Ori. Made worse by the fact most of the villain in the show trace their origins to the Ancients. The Goa'uld only got off their own planet thanks to the Stargate and much of the technology they reverse engineered was Ancient in origin. The Replicators are implied to have been created by the Ancients. The Ancients inadvertantly helped the Wraith develop and later created the Asurans to fight them. Finally, the Ancients refused to fight the Ori letting them enslave humans in multple galaxies for millennia.
  • No Good Deed Goes Unpunished: Any time one of them becomes too sympathetic towards humanity and decides to try and break the rules they can usually expect to face some nasty consequences.
  • No Name Given: The proper name of their species (assuming they didn't just call themselves humans like we do) is never revealed. Because of how incredibly old their civilization was, we only ever hear what others called them: the Ancients, the Ancestors, etc. Even "Alterans," their oldest known alias, just means "the Others" in their native language.
  • Sealed Evil in a Duel: The most consistent and reliable way to defeat an Ascended Being is for another Ascended Being to force them into combat, effectively trapping them both forever.

    Oma Desala
Played By: Carla Boudreau, Mel Harris
First Appearance: "Maternal Instinct"

The first ascended being encountered by the team, Oma was originally the guardian of the sacred temple at Kheb. She later helped Daniel to ascend when he was dying of radiation poisoning and became a sort of mentor figure to him, but turned out to have some dark secrets of her own when it was revealed she inadvertently helped the Goa'uld Anubis achieve ascension.


  • The Anti-Nihilist: Implied. She says that the universe is so vast and random that the only thing a person can truly control is whether they are good or evil.
  • Cruel to Be Kind: It's eventually revealed that she was the one who stopped Daniel from attacking Anubis when he was ascended, leading to the destruction of Abydos, but she claims that she only did so in order to spare him a much worse fate at the hands of the Others.
  • Cryptic Conversation/Hurricane of Aphorisms: A particular specialty of hers, as she has a tendency to speak in maddeningly opaque Koans. This is frequently lampshaded, and even becomes a plot point when Replicator Carter attempts to impersonate her in a Lotus-Eater Machine scenario.
  • Hash House Lingo: She adopts this manner of speaking when Daniel visits the ascended plane in "Threads", due to his envisioning her as a waitress at the "Astral Diner". Amusingly, it's probably the most straight-talking she's ever been.
  • Heroic Sacrifice: She stops Anubis from wiping out all life in the galaxy by forcing him to do battle with her for eternity.
  • Inscrutable Aliens: In her first appearance only, where she appears as a speechless, glowing ball of light with a face.
  • Loophole Abuse: She devotes her life to helping those from the lower planes ascend despite the fact that she's not really supposed to, but she admits that she "walks the line" and she can't break the rules in any more obvious ways without incurring the wrath of the Others.
  • Mother Nature: According to Daniel, this is the literal meaning of "Oma Desala", and she may have been responsible for inspiring the myth.
  • My Greatest Failure: Being tricked by Anubis, the most evil Goa'uld of all time, into helping him ascend and giving him access to vast amounts of power and knowledge.
  • My Species Doth Protest Too Much: She doesn't agree with the Others' "lower beings should have to achieve ascension on their own" policy and makes it her mission to help those she deems worthy. This has backfired on her at least once, but she's generally a lot more sympathetic to the plight of humans than the Others are, even if she can't always help.
  • Neutral No Longer: Anubis manages to push her into this with his gloating, causing her to make a stand against him and violate the non-interference policy to take him out.
  • Proverbial Wisdom: She is a wise superhuman being who always speaks in riddles and aphorisms.
  • The Punishment: The Others decide to punish her mistake with Anubis by basically refusing to do anything about him, forcing her to watch as he wreaks havoc on the galaxy. Apparently they don't much care about the thousands of innocent humans suffering right along with her.
  • Sealed Evil in a Duel: How she ultimately gets rid of Anubis.
  • Weather Manipulation: In her first appearance she summons a lightning storm to take out Apophis's Jaffa.

Played By: Lane Gates
First Appearance: "Secrets"

Not technically an Ancient at all, but the son of Sha're after she was impregnated by Apophis. As the offspring of two Goa'uld hosts, he was a Harcesis with access to the ancestral knowledge of the Goa'uld, and got taken in by Oma Desala to stop that knowledge from falling into the wrong hands. A later appearance reveals that he ascended at some point under her care.


  • Child by Rape: He's the product of Apophis raping Sha're while she was host to Amaunet.
  • Cryptic Conversation: Like Oma, he speaks almost entirely in Koans.
  • Living MacGuffin: As the Harcesis, he's hunted by just about every Goa'uld who knows of his existence. The SGC is also keen to find him for a while — ostensibly so that Daniel can fulfil his last promise to his wife, but mostly because he has access to a vast amount of information that could be immensely useful in fighting the Goa'uld.
  • Rapid Aging: He ages from a newborn baby to a boy of around ten in the space of a year due to nanites in his blood. The team conclude that as Apophis intended to use him as a host, he probably engineered him to reach maturity as soon as possible.
  • Things Man Was Not Meant to Know: After Daniel asks him to share the knowledge of the Goa'uld with Earth, Shifu gives him a dream to explain that the knowledge is corrupting and would cause him to become as evil as the Goa'uld himself if he had access to it.
  • Tyke-Bomb: His existence was specifically engineered by Apophis and Amaunet to provide Apophis with a new, more powerful host, going against the laws of the System Lords.
  • What Happened to the Mouse?: Despite the fact that he has the potential to be an immensely powerful character as an ascended being with access to the Goa'uld genetic memory, he's never seen again after season 4.

Played By: Sean Patrick Flannery, Cameron Bright
First Appearance: "Ascension"

An ascended Ancient who spent several years living in exile on an abandoned planet until SG-1 came along and he immediately fell in love with Sam, prompting him to take human form. He re-ascended again after being mortally wounded at the end of his introductory episode, but later returned in the form of a human child to help with the Ori threat several seasons later.


  • Ascend to a Higher Plane of Existence: He ascends for a second time after getting shot at the end of his first episode, when the Others decide to give him another chance.
  • The Bus Came Back: Initially a oneshot character in season 5, he later returns for two episodes in season 9 to help with the fight against the Ori.
  • Depower: Twice. He decides to re-take human form in his introductory episode in order to be with Sam, only to ascend again shortly afterwards. He then takes the form of an adolescent human boy sometime later, as it's the only way he can retain his Ancient knowledge and help the team without violating the non-interference clause.
  • The Dreaded: When a Prior sees him in his child form, he instantly panics. Justified, since he might be the most powerful mortal in the universe at that point, and the Priors are brainwashed into thinking the Ancients were horrible demons.
  • The Exile: He was originally exiled by the Others after helping the inhabitants of the planet Velona build a superweapon with which to defeat the Goa'uld.
  • Fountain of Youth: He's significantly younger looking when he returns in season 9.
  • The Jailbait Wait: Despite taking the form of a child when he returns, his feelings for Sam remain unchanged, but he tells her that he's aware a relationship between them would be taboo and he's willing to wait until he's the right age to pick up their relationship again. Naturally, Sam is somewhat creeped out by this.
  • Learnt English from Watching Television: He claims that he learned how to speak English and how to act and dress like a modern American human from watching Sam's TV overnight.
  • Loophole Abuse: He can't interfere to help the team against the Ori as an ascended being, so he takes the form of a young human which allows him to hold onto his ascended memories for a short period of time.
  • Love at First Sight: He claims to have fallen for Carter as soon as he saw her on the planet, which weirds her out some.
  • My Skull Runneth Over: Parts of his brain start to shut down as a result of trying to consciously hold onto his ascended memories as a human.
  • No Good Deed Goes Unpunished: Gets hit by this hard, on two separate occasions. In his backstory, his decision to help the Velonans overthrow the Goa'uld leads to them conquering other races with their new military power, which in turn prompts the Others to wipe them all out and banish Orlin. Then when he helps Earth against the Ori, he ends up getting stuck in the body of a twelve-year-old boy and suffering permanent brain damage, consigning him to spend the rest of his life in a sanitarium with no clue about what he once was.
  • Noodle Implements: He has a habit of building ridiculously advanced technology from scratch using random bits of crap he finds lying around Sam's house, which includes building a working Stargate with parts from her toaster.
  • Stalker with a Crush: He starts out acting this way towards Sam, following her home and telling her that he loves her. After she calls him out on it he tones it down a bit and they develop a friendship, though she never seems to fall for him in quite the same way that he feels about her.

    Morgan Le Fay
Played By: Sarah Strange
First Appearance: "The Pegasus Project"

A.K.A. Ganos Lal. The inspiration for the character from Arthurian legend. First appeared to Daniel and Vala as a hologram in the Atlantis database and gave them (very cryptic) information as to where they should look for the Sangraal, but was prevented from helping them further by the Others. She returned to help the team in Ark of Truth, and ultimately made a Heroic Sacrifice to finish off Adria.


  • Adaptational Heroism: Usually depicted as a villain in Arthurian myth, but she's one of the good guys here. If she hadn't destroyed the San Graal, the Others would have sent another. So, she did destroy it but also sealed and protected Merlin, so another could be made when needed.
  • Badass Boast: When she faces off against Adria at the end of Ark of Truth, after the latter lost her worshippers in the Ori Galaxy and been sapped of most of her power:
    Adria: You are no match for my power!
    Morgan: I am now.
  • Big Good: Took this role in season 10, constricted as she was. She provided information, nullified Adria's powers in critical moments, and finally performed a Heroic Sacrifice to defeat Adria once and for all.
  • Healing Hands: She heals Teal'c from a life-threatening wound after he's shot In the Back with an Ori staff weapon, allowing him to travel to Celestis to rescue Daniel, Vala and Tomin.
  • I Know Your True Name: Her name in Ancient is the only way to defeat the "dragon" guarding the transporter to Merlin's cave.
  • Loophole Abuse: She does this twice in order to covertly help the team without drawing the attention of the Others; first of all by posing as a hologram in "The Pegasus Project" and then by posing as the deceased Merlin in Ark of Truth. Daniel calls her on it both times.
  • Neutral No Longer: She finally takes a stand in Ark of Truth and forces Adria to do battle with her.
  • Public Domain Character: Based on the character from Arthurian legend.
  • Saying Too Much: Daniel is first clued into her not being a hologram when she accurately translates the Ancient phrase too quickly. The computer would have taken a few seconds, but she did it without any thought.
  • Sealed Evil in a Duel: She defeats Adria in a similar way to how Oma defeats Anubis.
  • Spirit Advisor: She appears to Daniel in the guise of Merlin throughout Ark of Truth in order to guide him to the Ark without overtly helping him. He sees through it eventually.
  • What the Hell, Hero?: Daniel subjects her to a lengthy chewing out over her subterfuge in both of her appearances.

Played By: Matthew Walker, Michael Shanks
First Appearance: "The Quest, Part 2"

Yes, that Merlin. An ascended Ancient who re-took human form some time ago in order to create a weapon capable of defeating the Ori, before he was placed in stasis by Morgan Le Fay. He died shortly after being found and thawed out by the team, but not before transferring his knowledge and part of his consciousness to Daniel so they could complete the weapon together.


  • As Long as It Sounds Foreign: While researching him Daniel sometimes refers to him by the name "Myrddin", from Myrddin Wyllt, his name in the original Welsh Mythology, but Michael Shanks badly mangles the pronunciation: it's supposed to sound more like "Muhr-thin" (in Welsh, the "dd" diphthong is supposed to be pronounced like the "th" in the word "the").
  • Cool Old Guy: It's Merlin. Despite the fact that he's disoriented and on the brink of death, he manages to freeze Ba'al's vocal cords with just a twitch of his fingers and spends some time telling Daniel and Vala about his many adventures before getting down to business.
  • Human Popsicle: By the time the team find him, he's been frozen in stasis for millennia.
  • I'm Dying, Please Take My MacGuffin: He quickly realizes that he doesn't have long left to live after the team thaw him out, and transfers his knowledge to an Ancient repository so that Daniel can finish building the weapon in his stead.
  • Pragmatic Hero: Merlin believes in the Ancient non-interference clause under most circumstances. But he recognizes the threat posed by the Ori is too great and is the only Ancient to decide to try to do something about it.
  • Public Domain Character: Based on the character from Arthurian legend.
  • Sealed Good in a Can: He was placed in stasis by Morgan prior to the events of the series so that those who proved themselves worthy by passing the tests she put in place could benefit from his knowledge.
  • Sharing a Body: It turns out that he somehow managed to upload at least part of his consciousness to the repository along with his knowledge and memories, and there are times during "The Shroud" where he appears to actually be in control of Daniel's body.
  • You Remind Me of X: When he first comes out of stasis, he mistakes the team for characters from Arthurian myth; specifically, he addresses Carter as "Guinevere", Mitchell as "Percival" and Daniel as "Galahad". The arguably funniest one is Ba'al, whom he associates with Mordred (while using his powers to strike him silent for probably the only time in the series).

Other Aliens

Played By: Frida Betrani
First Appearance: "The Nox"

One of the Nox, an elf-like Perfect Pacifist People from a planet called Gaia who keep to themselves and see humans as very young and primitive. Lya was the only recurring Nox and the only one known to willingly involve herself in affairs beyond her world.


  • Aliens Speaking English: At first, she and her people didn't speak English, but they learned very quickly (within a few minutes).
  • Can't Argue with Elves: Played straight with her people, but Lya eventually subverts this. At the end of "The Nox", SG-1 starts to agree with the Nox ways after the latter reveals the presence of their floating city and their own highly advanced technology with it. However, Lya is talked by Teal'c into doing some Loophole Abuse in "Pretense".
  • Death Is Cheap: She is killed by Apophis' forces and brought back to life. Justified, since the Nox have the power to bring back the dead.
  • Decided by One Vote: She becomes the swing vote in a trial set up by the Tollans between Skaara and Klorel. Justified because this is how the Tollans make trials impartial: one party expected to vote for each side plus a swing vote.
  • Friend to All Living Things: As a Nox, she values all life. This makes her the perfect impartial judge between a symbiote and its host. The main reason she voted for Skaara was that she was convinced that being a Goa'uld host is a Fate Worse than Death.
  • I Did What I Had to Do: Her reaction after the battle between the Goa'uld and the Tollans suggests that she is thinking this, since being an Actual Pacifist would mean that the Tollans would have been totally wiped out, something the Nox do not approve of.
  • Invisibility: The Nox possess this ability via their advanced cloaking technology. They use this to protect themselves and their planet, and Lya later uses it to help save the Tollans.
  • Loophole Abuse: The Nox are Perfect Pacifist People, but at the end of "Pretense", Lya hides and protects one of the Tollans' ion cannons so they can still fight back. She claims that she is still a pacifist because she never fired it, although she admits that she walked a fine line.
  • Master of Illusion: Lya uses her powers to hide one of the ion cannons from Zipacna's forces by making it invisible.
  • My Species Doth Protest Too Much: The Nox are isolationists who want nothing to do with war and find humanity too primitive to involve themselves with. Lya, however, comes to Earth to help the Tollans get to their new world, and before the Goa'uld can sabotage the Tollans' defenses, she hides one of their ion cannons.
  • Nice Girl: Daniel claims that "Lya likes everyone. That's the Nox way."
  • Obfuscating Stupidity: She and the other Nox pretend to be weak and helpless to put SG-1 through a Secret Test of Character. At the end, they reveal their ruse when they show SG-1 their floating city and just how advanced they really were.
  • Perfect Pacifist People: Her people won't resort to violence even in self-defense.
  • Put on a Bus: She hasn't been seen since season three because she went back to her planet and her people have buried their Stargate.
  • Really 700 Years Old: Her age isn't given, but the Nox can live to be about 500 years old. As an adult, she's probably at least a couple of centuries old.
  • Space Elves: The Nox are aliens who resemble elves or fairies. Given the fact that All Myths Are True in the series, they probably inspired the fairies of Earth mythology.
  • Sufficiently Advanced Aliens: The Nox eventually reveal themselves to be this; before then, everything they did could be mistaken for powerful magic or supernatural effects.
  • You Are a Credit to Your Race: Lya says this about Daniel: "Your race has learned nothing... but you have."

Played By: Dion Johnstone, Patrick Currie
First Appearance: "The First Ones"

An Unas who befriended Daniel. The Unas are reptilian aliens who were the first race used as hosts by the Goa'uld. Chaka eventually became a leader among his people and helped forge a tenuous alliance between them and the Tau'ri.


  • Alien Blood: As an Unas, his blood is bright green.
  • Androcles' Lion: Daniel references the trope by name when he helps Chaka by digging a bullet out of his hand.
  • Blood Is the New Black: After saving Daniel from a symbiote that tries to take him as a host, Chaka promptly rips it in half and smears its blood across Daniel's face.
  • Challenging the Chief: At the end of the episode, Chaka is able to finish off the alpha male of the Unas clan after O'Neill and Carter riddle it with bullets, prompting the other clan members to accept him as their new leader.
  • Enemy Mine:
    • Only comes into play at the end of the episode of the same name, when the Unas agree to work the naquadah mine in order to help the humans in the fight against the Goa'uld. The title of the episode is not actually a reference to this trope, however, but to the film of the same name.
    • The Unas themselves as they live on the planet divided up into many small tribes, but will immediately unite to fight an outside threat (such as the Humans).
  • I Choose to Stay: At the end of "Beast of Burden", Chaka decides to stay and lead the Unas in revolution rather than return to his home planet.
  • Interspecies Friendship: With Daniel. Only tentatively at first, but later appearances show them to actually be friends.
  • Lizard Folk: Like other Unas, he looks like your standard scaley alien with a humanoid build and a reptilian head.
  • Non-Answer: When Daniel and Chaka attempt to make contact with the native Unas, Daniel asks how long they're supposed to wait. Chaka's answer is simply "as long as it takes".
  • No One Gets Left Behind: Chaka refuses to go with the team and leave the other Unas behind when they first attempt to rescue him.
  • Tastes Like Friendship: Daniel begins to gain Chaka's trust by giving him a candy bar.
  • Translator Buddy: Daniel brings in Chaka for this purpose to help him communicate with the native Unas, since he doesn't understand enough of their language to handle the negotiations on his own.
  • What Happened to the Mouse?: Disappears from the series after his third appearance in season seven.
  • What Measure Is a Non-Human?: At first, Daniel seems to be operating under the assumption that the Unas are wild animals, but he quickly deduces that they must possess some degree of sentience, as Chaka is wearing clothes that he made himself and Daniel begins learning to communicate with him. In Chaka's next appearance, Daniel is outraged at another character's treatment of the Unas as they are sentient beings, while the other character sees them as "beasts" and can't understand why Daniel cares so much.


How well does it match the trope?
