Stargate SG 1: A To F
Tropes A-F | Tropes G-L | Tropes M-R | Tropes S-Z | YMMV | Shout Outs

Stargate SG-1 provides examples of the following tropes:

    open/close all folders 

    A 
  • Aborted Arc: The events of "Camelot" reveal that the time of King Arthur's prophesied return is approaching and that Valencia is destined to help him after she pulls the sword from the stone. SG-1 does spend several episodes following Arthur's trail to several planets, and eventually discovers Merlin's anti-Ori weapon, but the prophecy of Arthur's return is never followed up or explored.
  • Absent-Minded Professor: When Sam meets her boyfriend in a coffee shop, she mentions that there is no zoo in Colorado Springs. The screenwriters have heard of the Cheyenne Mountain Zoo, but the DVD commentary reveals that they wanted it clear that Sam has spent so much of her time working that she does not even know the layout of the city she lives and works in.
  • Absolute Cleavage: Ba'al's emissary to the remaining System Lords during the Cold Opening of "Reckoning, Part 1".
  • Abusive Precursors: The Goa'uld served as the foundation for many, if not all, human societies and religions prior to approximately 3000 BCE, but are a homicidal, imperialist and sadistic group that booby trap their leftover technology and return to exterminate any society descended from theirs that could rival them.
  • Action Survivor: Doctors Felger and Coombs have no combat training or experience, but when SG-1 was captured by Jaffa they both transport aboard the leaving ha'tak for a rescue mission. Of course, SG-1 allowed themselves to be captured and were quite unhappy to see the two scientists, but they came in handy later on.
  • Adam and Eve Plot: A primary purpose of the Alpha Site was to provide a haven for Earth's best and brightest should aliens conquer and/or destroy the planet. The SGC's heroics ensured it was never needed for that.
  • Adaptation Expansion: See Stargate, the original film.
  • Adventure Towns: Technically, adventure planets, but the effect is the same.
  • Aerith and Bob: SG-1 is primarily composed of humans with the human names of Jack, Daniel, Sam and Cameron, but includes alien members Teal'c and Vala.
  • Affably Evil: Ba'al
  • Affectionate Pickpocket: Vala in season 9 episode 3, asking for a parting hug from Daniel — to steal again the valuable artifact he'd just confiscated from her.
  • Agony Beam:
    • The Goa'uld Hand Device (also called a "Ribbon device" or "Kara kesh") is able to send a ribbon of energy into the head of another which causes extreme debilitating pain. This can be fatal if used extensively, and was also seen once to be able to send telepathic messages from one person to another.
    • The Goa'uld have a cattleprod-like device (never named in the series) that, when jabbed into a person, causes extreme pain without physical damage. When a person is being tortured with this device, light shines out of their mouths and eyes. Richard Dean Anderson did not like this visual effect, and would close his eyes whenever Jack O'Neill was being tortured in order to keep it from being used.
    • The first hit from a Zat'nik'tel supposedly induces enormous pain in the target. Teal'c mentions that the Goa'uld take great pleasure in doing this to victims.
  • Alien Blood:
    • First seen in "Tin Man" when Dr. Fraiser tries to draw blood from O'Neill, only to get a milky white lubricant instead.
    • Unas bleed green, and Goa'uld bleed blue. ("Thor's Hammer", "The First Ones")
    • Bounty Hunter Aris Boch in "Deadman Switch" is wounded by his quarry's weapons and forces Carter to do first aid on him. His species (the Ilempiri) bleeds green.
    • In "Foothold", Maybourne is convinced that the SGC has been invaded when Carter shoots the Stragoth impersonating O'Neill and Maj. Davis and reveals that the Stragoth bleed metallic purple.
  • Alien Non-Interference Clause:
    • The Tollan have a firm law against giving technology to less advanced species which they enacted after another planet destroyed itself (and the Tollan's original homeworld) after they were given technology too powerful for them to use responsibly.
    • The SGC refuses to give applied military technology to alien societies that are not being threatened by advanced outside alien invasion; they refuse to aggrivate the Space Cold War on Langara by providing Jet propulsion or SAM launchers, but do offer medical supplies and support in exchange for naquadriah.
    • Rule number one amongst the Ascended Ancients, which they believe in so strongly that they would rather die than break it, is to not interfere on the lower planes of existence, primarily with regards to helping "lowers" likewise ascend. Their belief is that if you deserve to ascend then you can do it by yourself, and all beings have the right to chose their own path without interference, even if that path ends in their own death. However, as Vala points out repeatedly in "The Pegasus Project", the Ancient rulebook seems to be constructed so that some level of interference is okay, by some Ancients, in regards to some humans, some of the time.
    • Subverted by the Asgard, who start out saying You Are Not Ready but then introduce their technology to the protagonists gradually with careful tutelage so they can learn to use it safely.
  • Aliens in Cardiff: Colorado Springs, actually, and justified by it being the closest city to Cheyenne Mountain, thus where SG-1, Weirdness Magnets all, live when off-duty. Also used in "Seth" with a rural area north of Seattle, WA, and in "Nightwalkers" with Steveston, OR.
  • Aliens Speaking English: Almost all Transplanted Humans speak English, even if they were transplanted before the development of English or from a territory where it is not commonly spoken even today. Most alien species have their own language, occasionally featured heavily, but most of them can also speak English at need when they need to communicate with any present humans. This fact is lampshaded in the 100th Episode, "Wormhole X-Treme!"; when told that there cannot be red apples on an alien world, the prop guy responds "Why not? They all speak English."
  • The Alleged Boss: A mild example is Colonel Mitchell in the last two seasons. While he's nominally the team leader, as he points out to General Landry Daniel and Teal'c are civilians and Carter's the same rank as him, while he's the new guy on a team of living legends, so getting them to do something they don't want to is a little tricky. Type 4.
  • The Alliance:
    • The Tau'ri, Tok'ra, and Free Jaffa ally against the Goa'uld about halfway through SG-1's run.
    • The Alliance of Four Great Races, composed of the Asgard, Ancients, Nox, and Furlings, which was formed millennia ago. The Asgard tentatively invite humanity to join as the Fifth Race in "The Fifth Race", but they are the only member to both remain in the galaxy and have regular contact with Earth.
    • During the Ori arc, the Tau'ri, Tok'ra, Free Jaffa, and Asgard ally against the Ori.
  • All Just a Dream:
    • "Forever in a Day". There are hints throughout the episode, but the implication is that the episode is actually happening, but with dream interludes. It is only at the conclusion that the entire plot is revealed to have been only a fantasy.
    • "Absolute Power", where Daniel learned the consequences of gaining access to the Goa'uld genetic memory.
    • "The Changeling" switches frequently between Teal'c's life at the SGC and a delusion where he is a human living a normal life on Earth. At the end, it is revealed that both lives were fantasies, and he was delusional as he struggled to keep both himself and Bra'tac alive after they were ambushed off-world.
    • In a way, "Shadow Play" also counts, as Dr. Kieran from Kelowna tries to get the SGC to assist him in staging a coup with the explanation that he is working with a larger resistance. In the end it is revealed that Kieran was a schizophrenic and all the Resistance scenes took place only in his head, and the scenes where the government tried to get Jonas' help in spying on the doctor was simply because they feared for his mental health.
  • All Myths Are True: A central premise, using the Ancient Astronauts variant. The gods of many ancient civilizations were Goa'uld, the Norse gods were Asgard, and the Greeks, Romans, and Celts were influenced by the Ancients.
  • All Planets Are Earthlike:
  • All There in the Manual: DVD commentaries explain a lot of the thinking that the writers, directors and actors put into the show to explain events that were not explored in the show itself. This includes information on the private lives of the characters, their history, and what happens off-screen between episodes.
  • All Your Base Are Belong to Us: In an alternate reality Daniel found in Season 1's "There But For the Grace of God", Alternate!Teal'c leads an attack on Stargate Command through the front door. He kills everyone except Daniel on his way to the Stargate.
  • Almost Out of Oxygen: In the episode "Tangent", Teal'c and O'Neill are trapped in a human-modified Death Glider that is on an uncontrolled trip out of the solar system with rapidly-dwindling life support. They do not expect to actually die from a lack of oxygen, but rather from high levels of CO2 after they run out of power and the life support systems can no longer recycle the air.
  • Alpha Bitch: "Kaegan" in the season 4 episode "Beneath the Surface" is a variation of this. Even though she's among the workers the same as everyone, she treats Carter horribly because she's so intelligent that she's coming up with ways to improve the plant, and sneers at anyone who is "sucking up" to the plant manager, treating anyone who is not "normal" with disdain and fear. More pointedly though, in a more straight male example, the Administrator who condemns the entirety of SG-1 to be slaves and then die because they rightly observed that the enslavement of half a society's population just so the other half can live in luxury and comfort is completely amoral and the treatment of those enslaved was terrible.
  • Alternate Landmark History: In "Avalon", Glastonbury Tor, a hill outside Glastonbury, England used heavily by the ancient Celts, turns out to have an Ancient installation and treasure trove beneath it.
  • Alternate Universe: Many are visited throughout the course of the show, which subscribes to the "Different outcomes for each decision" school of thought.
  • Alternative Number System: A throwaway line in "The Fifth Race" reveals that the Ancients used base 8.
  • Always Chaotic Evil: The Goa'uld. Repeated use of the sarcophagus causes paranoia, megalomania and delusions, and their genetic memory passes down experiences from Queen to spawn. Because of this, the Goa'uld are literally born evil.
  • Always on Duty: Everything interesting seems to happen when the base commander, and the rest of SG-1, is around. Lampshaded on one occasion where O'Neill gets in just as an Offworld Activation is going on. Teal'c, Daniel, and Sam are already in the control room. O'Neill points out that he just got in early, and asks what the others are doing there. Teal'c still lives on base at this point, Daniel says he came in as soon as he heard someone new was dialing in (though it's implied he never left the base), and Sam... well, she had been working so late that she hadn't left yet. This distresses O'Neill, who had apparently "ordered [her] to get a life". Fan writers are often fond of having both Sam and Daniel being ordered to go do something other than work and being forcibly removed from the base to make sure they do.
  • Amazon Brigade:
    • In the first season episode "Hathor", the men of the base have all been put under Hathor's mind control, forcing Carter and Fraiser to get the base's female personnel together to save the day.
    • The Hak'tyl (Liberation), a planet of refugee women Jaffa in the season 7 episode "Birthright". They reappear in "Sacrifices" and later as members of the Free Jaffa Nation.
  • Amnesiac Dissonance: Ke'ra from "Past and Present", who is one of the most popular and influential people helping to rebuild Vylus in the way of the global amnesia caused by the Vorlex, is revealed to actually be a youthful Linea, "The Destroyer of Worlds", the very person responsible for the disaster in her attempt to find The Fountain Of Youth.
  • Ancient Astronauts: The basic premise of the show. The gods of most of the world's mythology and religion were actually aliens who masqueraded as gods; in some instances the aliens inspired the legends, whereas in other instances they adopted the already-existing identity. The two primary mythologies used by the series were Egyptian (primarily used by the Goa'uld) and Norse (used by the Asgard), though Mayan, Aztec, Greek, Chinese, Minoan, Japanese, Celtic, Semitic, Hindu, Yoruba, Zen Buddhist and Christian mythologies were also involved.
  • Ancient Grome: The first season episode "Cor-ai" took place on Cartago (Latin for "Carthage") where the language apparently had roots in both Latin and Greek. Daniel is confused that the language would have two disparate roots.
  • And a Diet Coke: When Carter, O'Neill and Daniel each order four steaks, the two men look at her in surprise when Carter asks for a diet soda with hers. She explains that she likes the taste.
  • And Then What?: Seasons 8, 9 and 10 frequently highlight the fact that the Jaffa gave very little, if any, thought to what they would do after they overthrew the Goa'uld. This resulted in a lot of political infighting and presented many opportunities for unscrupulous people to take power through underhanded means. After the destruction of Dakara by the Ori, essentially destroying what government the Jaffa have, Teal'c and Bra'tac emphasize that it is just as important to plan for what to do after their victory as it is for them to fight the Ori.
  • And You Were There: In "The Changeling", where whilst suffering symbiote withdrawal, Teal'c reimagines SG-1 as a group of firefighters, where he is a human named T, who's far less stoic than Teal'c.
  • Annoying Arrows: Averted.
  • Arbitrary Skepticism:
    • Everyone finds the idea that Daniel had gone to an alternate reality to be completely ridiculous and thinks it makes him sound like a madman. This is after an entire season of alien planets, the crew being cloned as robots, literally dying, and seeing things that no one could explain.
    • The season after, the cast refuses to believe the spirits some displaced Native Americans tell them about could be anything else that completely imaginary. This coming from people who spend most of their time fighting Egyptian gods, and who have had their asses personally saved by Thor.
  • Archaeological Arms Race: There's a lot of this going on. Several Earth factions are desperate to get their hands on any alien technology in order to gain a political edge and also ensure survival against the Goa'uld threat. Meanwhile, all of the galactic factions (including Stargate Command) are scrambling to find any Ancient technology that might be left behind.
  • Archaic Weapon for an Advanced Age: Toyed with a couple of times. Energy weapons and bullets have no effect on Goa'uld System Lords' personal deflector shields, but they can be penetrated by slower-moving objects, a fact exploited by SG-1 on two occasions (for instance, Jack O'Neill throwing a rifle bayonet through Heru'ur's shield and through his hand in "Secrets"). In most other cases though, guns, regardless of form, rule the day.
  • Area 51: Functions as a research and development site where technology is transferred after it has been brought back to the SGC. Stargate Command itself is once referred to as "Area 52", which is its code name for government budgetary reasons.
  • Armor Is Useless
    • Standard kevlar body armor worn by USAF personnel have absolutely no effect on either staff weapons or zats (see also the entry on Bulletproof Vest below).
    • The metal armor worn by the Jaffa was extremely effective against Tau'ri weaponry in the early seasons (particularly in the first two fight scenes of the pilot), but was never seen to have any effect against staff weapons or zat'nik'tels. As the series progressed its effectiveness against projectile weaponry gradually lessened; by season eight it can even be penetrated by an arrow.
    • The armor worn by the Kull Warriors averted the trope. Though the Tau'ri and Tok'ra eventually developed an anti-Kull weapon, their armor remained impervious against both projectile and energy weaponry in every appearance.
  • Arson, Murder, and Jaywalking: "Thor's Chariot" has this exchange between Hammond and SG-1 regarding the Nice Job Breaking It, Hero situation on Cimmeria.
    Hammond: But let me play devil's advocate for a moment here. It's not our world. Is it really any of our concern?
    Teal'c: The destruction of the hammer device to save my life may have caused this. If so, I am responsible.
    O'Neill: General, I gave the order.
    Daniel: And I fired the staff at the machine.
    Carter: And I... was there.
  • Art Shift: In "Heroes", Emmett Bregman's footage has a different appearance from the rest of the show — more like a live TV program than Stargate's usual more cinema-like feel.
  • Artistic License - Military: This was mostly averted; as the series went on (and it became more and more supported by the US Air Force), the show got better and better at portraying the military realistically. That said, the earlier seasons saw some oddities pop up. In the pilot episode, for example, there was one character wearing the insignia of both a Staff Sergeant and a Major (he's jokingly referred to by the fans as Staff Sergeant Major Joe). There were also some flagrant errors in the early days regarding when and where it was appropriate to salute a superior officer, how said officers are addressed by both their subordinates and superiors, and just who you're supposed to report to when you're reporting for duty.note 
  • Artistic License - Medicine: A minor case in "The Broca Divide". Leaving aside whether a disease — even an Imported Alien Disease — is capable of causing humans to regress to a primitive state, Dr. Fraiser calls the microorganism a virus. Viruses use cells to replicate, plain and simple. They do not consume chemicals in the bloodstream. If it had actually been a virus, antihistamines would have had absolutely no effect on it. She also calls it a "parasitic virus" at least twice. Viruses are parasitic by definition.
  • Ascended Meme: Fans of the show had for years used the term "kawoosh" to refer to the unstable vortex of an opening Stargate; in "Crusade", the penultimate episode of season nine, Carter uses the term.
  • Ascend to a Higher Plane of Existence: The Ancients ascended en masse and a few of their number, primarily Oma Desala, help other individuals ascend as well. However, their official policy is one of non-interference and they believe that anybody who should ascend will be able to do it by themselves. Daniel Jackson spent season six as an ascended being, but was forcibly returned to the normal plane in season seven. Season nine introduced the Ori, a sister-race to the Ancients who likewise ascended en masse, but believe in dominating the lower races in order to enhance their own power.
  • As Himself: Generals Michael E. Ryan and John P. Jumper, successive Chiefs of Staff of the Air Force, appeared on SG-1 playing themselves.
  • Asskicking Equals Authority:
    • The Goa'uld select a Jaffa as their First Prime based on their military skill and experience. If a Jaffa wishes to depose the current leader he may challenge him to ritual combat for the position.
    • The traditions fostered by the Goa'uld are unfortunately very hard to get rid of once the Jaffa gain their independence, and the Free Jaffa Nation initially awards positions on its leadership council based on the military assets controlled by different Jaffa factions. This essentially gives Gerak, the former First Prime of the minor Goa'uld Montu, control of the new nation since Montu had served Ba'al and Gerak laid claim to the majority of Ba'al's forces.
  • As You Know: Done every now and then by Carter and/or Daniel whenever we need exposition about a group that the team has encountered in a previous episode. Played for Laughs once when an ascended Daniel shows up in an elevator and dumps some exposition on Jack, and Jack then forces Daniel into a Seinfeldian Conversation, then proceeding to tell Daniel about what he just told Jack.
  • Atlantis: The majority of season seven was spent searching for the Ancient's last and greatest city in the hope that its technology could protect Earth from the Goa'uld. In the episode "Lost City" they discover that this city, named "Atlantis", was formerly located in Antarctica, but that it has since moved. The spinoff, Stargate Atlantis, followed the expedition that located and explored the city itself.
  • Avoid the Dreaded G Rating: "Children of the Gods", the two-hour premiere episode of the series, features full-frontal female nudity that was added in order to classify SG-1 as an "adult" show. This scene is retained in the DVD release, where the episode is rated "R" by the MPAA, but cut out of all syndicated airings. When the episode was re-cut in 2009 and released as a DVD-film this scene was removed in order to reflect the original intention of the showrunners.
  • Awesome, but Impractical: Standard Goa'uld design philosophy.
    • Staff weapons are great at terrorizing primitive societies and are by no means a laughing matter, but compared to Tau'ri firearms they are inaccurate (there are, after all, no sights) and short-ranged. Lampshaded by O'Neill in "The Warrior" when he explains that the staff is a weapon designed to intimidate, while the FN Herstal P90 favored by the SGC is a weapon designed to kill.
    • The Death Glider can fly in space and in atmosphere and is specifically designed to terrify enemies. It also has no autopilot, ejector seat, targeting systems, or friend-or-foe recognition, and relies purely on line-of-sight weapons. The SGC reverse-engineered the essential systems of the Glider (engines, inertial dampeners, and so on) and added all the trappings of a modern jet fighter, creating the vastly superior F-302.
    • The Needle Threader, a Glider variation designed to fly through Stargates, which is an obvious tactical advantage. But unlike other ships designed for that purpose (the Ancient Puddle Jumpers and Wraith Darts), the Needle Threader doesn't have automatic navigation for flying through a Gate. The pilot has to do it all by himself; the Needle Threader has only inches of clearance when passing through the Gate. It takes a truly spectacular pilot like Master Bra'tac or Teal'c to successfully "thread the needle"; a more likely result is sheering off one of the wings and crashing on the other side of the Gate. It should come as no surprise that the Needle Threader was deemed a failure and abandoned. While the Goa'uld considered both Jaffa and Death Gliders to be entirely expendable, they preferred to have them at least kill some enemies before dying.

    B 
  • Back for the Dead: Major Kawalsky was one of three survivors of the original Abydos mission. He is taken over by a Goa'uld at the end of the pilot, and killed in the next episode.
  • Back from the Dead:
    • Daniel Jackson was written out of the series at the end of season five when Michael Shanks left the series; the character ascended after exposure to a lethal amount of radiation. When Michael Shanks returned for season seven, the character descended to our plane of existence.
    • Apophis died at the end of "Serpent's Song", but was resurrected by Sokar for further torture and returned in "The Devil You Know".
  • Badass:
    • Teal'c can knock a man out with an avocado at 100 yards. He is the only character in the series to wield two weapons that are not meant to be used as such, including two staff weapons and even two P90s, and on occasion even carries a Death Glider cannon.
    • One of the things that makes most Jaffa mere mooks is the Awesome, but Impractical nature of their Goa'uld-provided weaponry. Since staff weapons have no sights of any kind, the best they can do is point in the general direction of the enemy and volley fire. For Teal'c, that just doesn't matter. He's frighteningly accurate even when dual-wielding staff weapons. His mentor, Bra'tac, is just as good at this instinctive aiming. It helps that they're both over a century old, and have spent most of their lives either in battle or training for battle.
  • Badass Bookworm:
    • Samantha Carter is a decorated astrophysicist with complementary armed and unarmed combat training.
    • Daniel becomes a skilled combatant between seasons 1 and 10; unable to even properly reload his weapon in the early seasons but taking an active part in combat rescue missions in the latter.
  • Badass Crew: SG-1. Several enemies wanted to destroy the Earth just to ensure that those four would be dead.
  • Bad Future: "2010", which initially looks like a good future. The Goa'uld have been defeated, the Jaffa liberated, and Earth is a member of the Aschen Confederacy, which has granted the planet advanced technology. However, it turns out that the Aschen are simply a much more patient alien menace, and have been reducing human fertility with the plan to conquer the planet without firing a shot once the human population dies out.
  • Baddie Flattery: Hathor to Carter: "You are an exceedingly beautiful woman."
  • Bald of Awesome:
    • Teal'c before season eight, much to Christopher Judge's dismay, who regularly shaved his head.
    • General Hammond remained bald throughout the shows run and was even described as such by Colonel O'Neill on several occasions. Bra'tac had a habit of pantomiming Hammond's baldness when referring to him.
  • Bald of Evil: The System Lords Heru'ur and Sokar.
  • Ball of Light Transformation: People who Ascend to a Higher Plane of Existence take the form not of a ball of light, but of a luminous blob with waving tendrils, sometimes dubbed a "light jellyfish". Ascended Ancients can then take this form at will, but they're pretty much Energy Beings all the time by this point — though they can also resume a material form if they wish.
  • Bar Brawl: SG-1 starts a brawl at "O'Malley's in town" while under the mind-affecting, strength-enhancing Atoniek armbands.
    O'Neill: Well, this is a cliché.
  • Battle Discretion Shot: The aforementioned Bar Brawl cuts to the exterior of O'Malley's, whereupon we hear a string of crashes, thuds, and shattering glass. It is hilarious.
  • Battle in the Rain: It is raining throughout "Camelot" (although it is very hard to notice on-screen) and, though it (Might have) stopped by the time of Mitchell's fight with the Black Knight, the ground is thick mud that ends up completely coating Mitchell as he is tossed around during the fight.
  • Beard of Evil:
    • In the episode "Point of View", SG-1 travels to an alternate reality in which Teal'c is still First Prime of Apophis and the Goa'uld have taken over the Earth. The alternate Teal'c has a beard, as does Apophis, but this Teal'c is killed before he is really given a chance to show where he falls on the morality scale and Apophis is no worse (or better) than the "real" Apophis.
    • Lampshaded by Colonel Mitchell in "Ripple Effect":
      Mitchell: Well, you don't have beards, so I'm guessing you're not from the Evil Twin universe.
  • Because I Said So:
    O'Neill: I always have a reason that I'm not required to explain. It's a military thing.
  • Becoming the Mask:
    • In "It's Good to Be King", Harry Maybourne is revealed to have conned the inhabitants of a world into believing him to be a prophet, even making him their King. He's as surprised as everyone else to realise that he genuinely has become the wise and benevolent leader they all saw him as, responsible for introducing new laws and technology to improve their society, with no selfish motives whatsoever.
    • In "Fallout", Kianna genuinely falls in love with Jonas Quinn, despite being a Goa'uld spy sent to seduce him.
  • Beethoven Was an Alien Spy: Literal example. Yu the Great, one of China's earliest emperors, was one of the Goa'uld System Lords.
  • Belief Makes You Stupid: A few First Contact episodes involve dealing with the fallout from confirming/disproving the beliefs that the natives have about how they arrived on the planet.
  • Belligerent Sexual Tension: Gender-Flipped with Vala as the Jerk with a Heart of Gold and Daniel as a type "B" Tsundere.
  • Beneficial Disease:
    • In a somewhat roundabout way, early episode "The Broca Divide" has Daniel's infamous (and soon forgotten) allergies prove to be beneficial, in that the antihistamine medication he takes for it proves to be the cure for the neanderthalism-inducing disease plaguing the locals.
    • In one episode, the characters receive armbands that bestow superpowers on the wearers. They work by infecting the wearer with nanites that causes the changes. Unfortunately this means that the armbands only work for as long as it takes the body to develop an immunity to the nanites.
  • Benevolent Precursors:
    • The Asgard are this in regards to the Tau'ri. During antiquity, they posed as Norse gods to guide the more primitive humans, and during modern times they help out the Tau'ri when they can. They have a distinction in that they're still around (at least until the series finale).
    • Seasons 9 and 10 reveal that the Ancients, whose core policy is non-intervention on the lower levels, have been active on their own level with regards to the Ori.
  • Berserk Button: Do not refer to a Tok'ra as a Goa'uld.
  • Beware the Nice Ones:
    • Samantha Carter, the one member of SG-1 who never displays any personal hatred against the Goa'uld and who is the most level-headed of the group, is the one whose skill and experience blew up a sun.
    • The Asgard, particularly Thor. They are a wonderfully benevolent and understanding people, even treating the Goa'uld with a measure of respect... but if you try to invade a world they protect, Thor will descend from on high in his ship and seriously fuck you up. And without any mess, too.
  • BFG: As the team's Big Guy, Teal'c is fond of these, be they squad-support machine-guns, grenade launchers, anti-armor missile launchers, or even a friggin Death-Glider cannon he slings from his broad shoulders.
  • Big Bads:
    • The Goa'uld were the traditional Big Bad of the first eight seasons, represented at different times by whichever Goa'uld had risen to prominence.
      • Apophis, who was frequently defeated and then returned stronger than before.
      • Anubis, a partially ascended Goa'uld.
      • Ba'al, a relatively minor Goa'uld who played second fiddle to numerous other Goa'uld, eventually managed to outlive and surpass them all in prominence and threat level.
    • The Ori replaced the Goa'uld as the ever-present Big Bad in seasons nine, ten and the first SG-1 movie, The Ark of Truth. They were represented by their Dark Messiah, Adria.
  • Big Bad Ensemble: This series almost always had one single Big Bad whom SG-1 had to contend with. In the later part of season 8, however, they were simultaneously faced with two Galactic Conquerors: the Goa'uld System Lord Anubis, an immortal Energy Being who is leading the combined Goa'uld forces behind the scenes with Ba'al as a puppet, and Replicator Carter, the humanoid leader of the Replicators, a Horde of Alien Locusts. The Replicators proceed to invade the Milky Way to consume everything as the two evil factions duke it out among each other, while SG-1 and the Free Jaffa try to take Dakara to free the Goa'uld-dominated worlds. Anubis wants to use a weapon on the planet to wipe out all life, while RepliCarter tries to find a way to destroy Anubis and rule herself.
  • Big Damn Heroes: The Asgard have a penchant for being awesome and arriving at the last minute, but the end of the season 2 episode "Thor's Chariot" encapsulates that, with a huge hammer-shaped starship coming down out of the clouds to quite literally eliminate every living Goa'uld and Jaffa on the planet (minus Teal'c). Counts as a Moment Of Awesome.
  • Big Eater:
    • When Jonas Quinn was introduced he became fascinated with "traditional all-American food" and was shown eating in every episode he was in, often more than once in an episode. Carter noticed this and commented that America has another tradition, hardened arteries, and this facet of his character was dropped towards the middle of the season.
    • Nerus, the Goa'uld inventor, whose appetites are so large, and so well known, that food is used as a method of information extraction.
      Nerus: General! This chicken is most PLUMP and DELICIOUS. You spoil me general!
      Landry: It's called turkey, another rare delicacy.
      Nerus: Well I MUST have more turkey!
  • Bigger Bad:
    • Ra was the first Goa'uld to find Earth and use a human as a host, which gave him and other Goa'uld a massive supply of hosts, soldiers and slaves and allowed them to spread all across the galaxy, with Ra as the top System Lord for over ten thousand years. He's killed off in the original film before the series, but his legacy poses the main threat for most of the series.
    • In seasons nine and ten, the Ori are the Bigger Bad, since they're ascended beings and thus more of a concept rather than actual characters. Their Dark Messiah Adria takes on the Big Bad mantle for season ten.
  • Big Good:
    • The Asgard are all that prevent the Goa'uld from launching an all-out attack on Earth that the planet would have no hope of surviving.
    • The Ascended Ancients are all that have kept our galaxy hidden from the Ori for millennia, and who prevent the Ori from using their Ascended abilities directly.
    • Humanity slowly evolves into this over the course of the series. With the death of the entire Asgard race, Humanity is now the main Big Good of the Milky Way, as well as making up part of a Big Good Ensemble, with the Tok'ra and Free Jaffa Nations.
  • Big "NO!": Courtesy of Apophis and Anubis, and other Goa'uld. Being an entire race of megalomaniacal Large Hams, it fits.
  • The Big Race: Season seven episode called, appropriately, "Space Race".
  • Bilingual Backfire: In "The Scourge", Daniel Jackson and Shen Xiaoyi briefly converse in Mandarin, during which they briefly insult Mitchell, only for Mitchell to respond (in Mandarin) "Screw you!"
  • Bilingual Bonus:
    • Spoken Russian appears (relatively) frequently throughout the show, often commenting on the series itself.
    • In "The Scourge", Daniel Jackson and Shen Xiaoyi briefly converse in Mandarin after being introduced.
      Shen: How's your Mandarin?
      Jackson: Not as good as your English.
      Shen: It shows. (about Mitchell) You're bringing him along?
      Jackson: We have to baby-sit him.
      Mitchell: (in English) Yeah, that's very funny. (in Mandarin) Screw you!
    • In the 2nd part of "Small Victories", a crewmember of a Russian submarine wonders what's making these noises on the torpedo tube. The other one says (in Russian with ear-splitting accent) that it's "probably the insect from last episode".
  • Binary Suns:
    • In "Children of the Gods", Teal'c's homeworld Chulak is revealed to orbit a binary.
    • In "The Fifth Race", Teal'c, Carter, and Daniel are briefly trapped offworld when the second sun rises and causes the DHD to overheat.
    • As stated in "2010" and "2001", the Aschen have the ability to create Type III binary star systems by inducing fusion in hydrogen/helium gas giants.
  • Biological Weapons Solve Everything: The Aschen use super bacteria as a means of destroying any opposition on any newly conquered planets. Once the weapon has killed all infrastructure they come in and make themselves look like heroes.
  • Bishonen Line:
    • Anubis. For most of the series, his appearance is that of a cloaked figure, revealed to be a dark, shadowy form of energy. When said shadow-being loses the forcefield containing it, Anubis then takes to possessing various human hosts (seemingly "burning them out" in the process). His "final form" (at least, the last time we see him) is a creepy fat guy in a wafflehouse. note 
    • The Replicators start out as a ravenous, all-consuming horde of spider-like machines whose sole purpose is to assimilate everything to make more of themselves. The humans then started to encounter larger and more dangerous Replicators such as Queens, who produced even more of the regular ones. Then after the Replicators assimilated the android who designed them in the first place, they evolve into human-form replicators. These Replicators were more dangerous and intelligent then any of them, and also sentient to the point that they clearly showed sadistic or compassionate streaks.
  • Bitch in Sheep's Clothing: RepliCarter in her first appearance, where she cons SG-1 into helping her destroy Fifth, become the new leader of the Replicators and get immune to their Anti-Replicator Weaponry. Oops.
  • Bizarre Alien Sexes: The Goa'uld are asexual, either taking the gender of their host or choosing hosts specifically with their gender of preference. They are also all sterile, aside from the Goa'uld Queens, who can give birth to dozens, if not hundreds of larvae at a single time. While "Hathor" claimed that the host's DNA is needed in the process, this was quickly retconned as the writing staff consider this episode Canon Discontinuity.
  • Black Girl Dies First: Mala of the Hak'tyl was the only one of her tribe not to survive the tretonin tests.
  • Black Knight: Two of Merlin's holographic Knights appear in season nine. The first is a type of test to judge a challengers worthiness, and the second is a security system designed to protect Merlin's library. The first is dressed in shining armor, but the second, designed to scare the villagers and kill trespassers, is solid black.
  • Black Speech: The language of the Goa'uld.
  • The Blank: When we finally see Anubis' face, it's just a dark swirly energy-thing.
  • Blatant Lies: In "Disclosure", courtesy of the Chinese ambassador.
    "The Chinese government does not believe in keeping secrets from its people."
  • Blind Without 'Em: This is how the team realizes that Russian General Miraslov Kiselev has been implanted with a Goa'uld in "Full Alert" since it's documented that he has glaucoma and should need glasses.
  • Blood-Stained Letter: "2010" has an Ominous Message from the Future appear through the gate, written in Jack O'Neill's handwriting, and stained with blood, warning them not to go to a certain planet. They're Genre Savvy enough to do as it says, especially after they tested the blood and determined it was O'Neill's, thus proving the letter to be a Note to Self.
  • Blue and Orange Morality / Above Good and Evil: One way to view the (non-human-form) Replicators. All they care about is making more of themselves. They have no interest at all in humanity or the other species, we are just in their way.
  • Bluff the Impostor: In "Holiday", O'Neill tests "Ma'chello" by asking about the dress Daniel's sister wore when she and Jack went on a date. His response, that Daniel does not have a sister, and that if he did he would not let Jack near her, convinces him.
  • Blunt Metaphors Trauma: Teal'c, Vala, Bra'tac and Thor... basically, every friendly Proud Warrior Race Guy and every Sufficiently Advanced Alien who has not already ascended to a higher plane of existence. Teal'c eventually got enough exposure to Earth culture to avert this trope in later seasons.
  • Boarding Pod: A variation. As seen in "New Order, Part 1" the Replicators board enemy ships by firing a projectile composed of Replicator blocks at them. Upon impact the blocks reassemble into combat forms and cut through the hull.
  • Board to Death: Ba'al to all his clones in the penultimate episode. At least most of them.
  • Body Backup Drive: The Asgard exist entirely as a race of clones, and regularly transfer their consciousness from one cloned body to a new one. Thor, voiced by Michael Shanks, dies repeatedly over the course of the series, only to return in a new cloned body.
  • Boggles the Mind: One episode has O'Neill doing a crossword after downloading the Ancient database into his head (again) as he waits for his subconcious to gain access to the knowledge, including where the MacGuffin they need is. Dr. Jackson notices he's been unconciously filling in answers in Ancient, and theorises that these are clues to where they need to go (he's right). Carter remains skeptical because he also filled in "celestial body" as "Uma Thurman".
  • Bold Explorer: The whole purpose of the team was to go through the Stargate and see what they could find on the other side.
  • Boldly Coming:
    • In the first episode to feature the trope in its purest form, the show examined the inherent problems that come with sleeping with random women with different biology: O'Neill catches an STD and nearly dies.
    • It faded away as the series progressed and situations which dealt with this generally addressed the natural repercussions of such of a relationship, though SG-1 never did completely abandon the premise.
      Jack: Daniel, you dog! Keep this up, you'll have a girl on every planet!
    • Lampshaded by Vala, who says that the real reason for them joining the Stargate program is to meet women. Landry and Mitchell agree, Daniel doesn't.
  • Book Burning: A platoon of Ori soldiers does this to the entire contents of a town library in "The Quest", calling them unholy and counter to Ori teachings. Daniel, looking on, silently fumes.
  • Boom Stick:
  • Boring, but Practical: "The Tau'ri weapons are primitive, but impressive."
  • Boss in Mook Clothing: Anubis's Kull warriors. Their armor is impervious to everything from machine guns to staff weapons to claymores and equipped with dual wrist-mounted rapid-fire staff weapons. Killing them requires a specialized energy weapon that negates the advanced technology that granted them life in the first place (or the kinetic energy of something on the order of a heavy artillery shell, which isn't exactly man-portable).
  • Bothering by the Book: When a documentary begins filming the SGC, over the protests of General Hammond, Hammond explains that he will follow the precise letter of his orders, using minor technicalities to keep what he can out of view of the cameras.
  • Bottle Episode: Season eight's "Prometheus Unbound" and "Gemini" were filmed concurrently, each with only about half the cast, in an attempt to save money. Carter and Teal'c did not appear in "Prometheus Unbound", and O'Neill only had a single scene at the episode's opening, with Daniel only appearing in the opening scene of "Gemini". Ironically, due to the unexpected volume of special effects in "Prometheus Unbound", the episode wound up costing more than the usual SG-1 episode.
  • Bounty Hunter:
    • Aris Boch, a Punch Clock Villain in "Deadman Switch".
    • In "The Ties That Bind", Mitchell and Teal'c pose as bounty hunters in order to trick Jup and Tannat, two aliens that had a grudge against Vala and Daniel.
    • A whole batch of them come after SG-1 in "Bounty" after the Lucian Alliance puts a price on SG-1's heads.
  • Brainwashed: Several times.
  • Break the Cutie: Done to multiple characters, but SG-1 BEGINS with it being done to Daniel Jackson. The result is an understated subtext, but it's pretty clear the vengeance he wants is to exterminate the Goa'uld as a species.
  • Brick Joke:
    • In "The Fifth Race", Jack and Teal'c spar in a boxing ring. Teal'c decks Jack. In "Upgrades", with the benefit of an Atoniek armband, Jack decks Teal'c.
    • An even longer brick joke occurs between the third episode, "The First Commandment", and the two hundredth episode, the appropriately titled "200". In "The First Commandment" Jack O'Neill orders two separate people to go back through the Stargate to give General Hammond a sitrep, and both times his orders are refused. He then pauses and says, "'No sir.' 'No sir.' Does it say Colonel anywhere on my uniform?" In "200", Jack O'Neill's Wormhole X-Treme! surrogate, Colonel Ace Danning, says, "As a matter of fact, it does say Colonel on my uniform!"
  • Broken Aesop: The Nox, in season 1. These Perfect Pacifist People tell the unit "you should learn that your way is not the only way", and to basically show that pacifism is the way to live... However, firstly the Nox do not accept any way but their own, being insufferably condescending to SG-1 about their actions, taking away their weapons and forcing them to follow their path. Secondly, the only reason they can afford to be pacifists is that they can bring people back from the dead and have advanced technology to shield themselves, without which they would be dead. No-one seems to call them out on their hypocrisy, though. They also refuse to even try to be friends with Earth by the end of the episode. But are later shown to have befriended the Tollan, who aren't warmongers, but are clearly willing to kill to defend themselves, when even that seriously offended the Nox when they met SG-1.
  • Broke Your Arm Punching Out Cthulhu: A couple of times:
    • The first 8 seasons consist of the Tau'ri and their allies trying to avoid (and sometimes causing) Type 6(ish). As the Tok'ra are fond of saying, lots of warring Goa'uld are preferable to one all-powerful Goa'uld.
    • In season 10, SG-1 manages to "kill" all of the Ori (they're energy beings so "kill" isn't quite the right word), but this doesn't stop their followers from continuing their war on the galaxy. And to do so, they had to send the device to the Ori home galaxy, which then meant the Ori could dial into our galaxy again. They then sent several more of the vastly powerful Ori ships into the Milky Way galaxy, which effectively made things worse in the short run. It also means that when Adria ascends, she now has all the power that was once split among all the Ori. This makes her insanely powerful.
  • Bug War: Season nine's "The Scourge", at the end of which the team decides to watch Starship Troopers for movie night.
  • Bulletproof Vest:
    • A realistic depiction. When O'Neill is shot in the back with a silenced pistol the vest manages to stop one of the bullets, but the other bullet hit his (non-armored) shoulder and penetrates, and the impact from the bullet that is stopped still broke a rib and knocks him unconscious.
    • In "Heroes", Dr. Bill Lee explains why standard bulletproof vests do not work against staff weapon, and in some cases actually amplify the effects by trapping the heat of the blast within the vest and cooking the wearer. So the SGC develops a ceramic insert for the standard USAF flak jacket to absorb the blast. The inserts end up saving Jack O'Neill's life.
  • Bullet Sparks: Particularly when machine-gunning enemy Jaffa.
  • Bunny-Ears Lawyer: Pretty much every major military role in the series is this to some extent. Jack O'Neill turns it Up to Eleven, by making insubordination into an art form. Word of God (from real USAF generals that Richard Dean Anderson has asked about it) is that there are real colonels who are much worse than Jack.
  • The Bus Came Back: Jonas in "Fallout".
  • Busman's Holiday: When Colonel Mitchell joins General Landry for a vacation at General O'Neill's cabin, they discuss hunting and Mitchell points out that his day job involves him walking around a forest with a gun. When he later is required to go out hunting (for a dangerous monster) he points out that it is just his day job all over again.
  • Butt Monkey:
    • Sgt. Siler, as the Mauve Shirt who is constantly subjected to non-fatal accidents and injuries. It makes sense when you remember that his actor is the stunt coordinator for the series.
    • A darker version of the Butt Monkey would be Major Kawalsky, who was killed in the second episode. He reappears in time travel or alternate universe episodes only to die in most of them as well.
    • Lieutenant Grogan appears in two episodes and O'Neill, despite admitting that he is a fine officer, points out that is very good at getting himself shot. He was shot four times in his first appearance, then got trapped off-world by Svarog's Jaffa in his second one, and shot again with a zat.
    • Dr. Lee, a scientist who's not as smart as Carter (though he's smarter than Felger) and whose job in the show is mostly to be Entertainingly Wrong.
  • But You Were There, and You, and You:
    • "The Changeling" recasts the members of SG-1 as firefighters living a normal life on Earth. Teal'c is a human, Bra'tac (referred to as "Bray") is his stepfather who needs a kidney transplant, O'Neill is the fire chief, Carter is a crew captain, Jonas is "Probie" ("Probationary firefighter") and Siler opens the door. Daniel Jackson appears as a psychiatrist, but there are hints (and it is confirmed at the end of the episode) that he is the real Daniel.
    • In "200", Vala pitches to Martin Lloyd a thinly-disguised retelling of The Wizard of Oz, describing it as an adventure she had before joining the SGC. Carter is the "lovely, fair-haired Tok'ra" (Glinda), Landry is the wise Ascended being (Oz), she takes the Dorothy role and Mitchell, Daniel and Teal'c are the Scarecrow, Cowardly Lion and Tin Man, respectively.
  • By the Eyes of the Blind:
    • The Goa'uld literally have naquadah, the rare mineral that is used to build the Stargates and much Ancient and Goa'uld technology, in their blood. As such they can sense/be sensed by other Goa'uld, Jaffa or people who likewise have naquadah in their bloodstream.
    • The Reetou, an insectoid alien species that are invisible to all known species, can be "sensed" by the Goa'uld and, by extension, the Jaffa (through the Goa'uld symbiotes they carry). This "sensing" was used to develop a technology to make them visible.
    • In season six, an alien device made whoever touched it (and whoever touched them) able to see alien creatures "out of phase" with our reality. The creatures themselves did absolutely nothing, they had been on Earth all along and could not interact with physical matter, but suddenly seeing them caused widespread panic.

    C 
  • California Doubling: Canadian variant.
  • Call Back: In "Citizen Joe". Aside from it being a Recap Episode, the eponymous Joe also makes mention of several minor jokes that have no bearing on the plot, such as Jack's analogy in "Lost City" in which he compares Mr. Burns to a Goa'uld.
    Joe: Between you and me, I totally see the analogy: Burns as Goa'uld.
    Jack: Thank you.
  • Cannot Tell a Joke: Teal'c. Humor, as the Jaffa understand it, is esoteric, to say the least.
    Teal'c: A Serpent guard, a Horus guard, and a Setesh guard meet on a neutral planet. It is a tense moment. The Serpent guard's eyes glow. The Horus guard's beak glistens. The Setesh guard's... nose drips. (laughs uproariously)
  • Canon Discontinuity: The original rule for the zat'nik'tel was that one shot hurts, two kills and three disintegrates the body. However, as the seasons progressed the third shot effect was gradually dropped, disappearing entirely in season three. In the self-referential "Wormhole X-Treme!", the on-site director refers to the three shot rule as the stupidest thing he has ever heard.
  • Can't Argue with Elves: The Nox are a race of technologically advanced beings possibly on par with the Ancients, yet are still perfectly in tune with nature, and are complete pacifists. But the only reason they can get away with this pacifism is because they are so advanced, yet speak with condescension and superiority to less advanced cultures like Earth who do not have the technological superiority that allows the Nox to not be wiped out. And they won't share a single part of that technology. They make the Ascended seem humble at times.
  • Can't Get Away with Nuthin' : In "Endgame", it is when Walter is taking a break for a cup of coffee, the only break we see Walter takes in the entire series, that the Stargate is stolen. When Daniel discovers this he briefly begins yelling, but then tells him that the coffee break had nothing to do with the gate being stolen and not to worry.
  • Can't Live Without You:
    • The Jaffa cannot live without a Goa'uld in their pouch until a drug that has the same effect is discovered in one of the later seasons.
    • In the opening story arc of season 9, Daniel and Vala put on bracelets that create a link between them so that to be any more than a few feet away from each other can cause them extreme physical discomfort and eventually death.
  • Card-Carrying Villain: Anubis; when "Jim" is speaking with Daniel Jackson in the Astral Diner he explicitly points out that the Goa'uld are evil and that Anubis is the worst one of the lot.
  • Cargo Cult: Many of the less advanced cultures on the show who have had exposure to advanced technology from other worlds end up worshiping it in this manner. When otherworldly beings are treated as gods thanks to possessing this techology, it's God Guise (refer to the G to L section). This happens quite often, especially with the Goa'uld (by design and with malicious intent), and sometimes benignly with the Asgard.
  • Cartwright Curse: Carter was known as "Black Widow Carter" behind the scenes as her romantic interests continuously died or were subjected to horrific torture throughout the series; she even acknowledges this to her boyfriend. Pete Shanahan was introduced in season seven partly because the writers specifically wanted to give Carter a life outside the Gate Program that did not end up being destroyed at the end of the episode where it was introduced.
  • Cast from Hit Points: When Daniel briefly becomes a Prior of the Ori and gains their powers, they work this way. He collapses from exhaustion when he exerts himself too much.
  • Casual Danger Dialogue:
    • In season nine's "The Scourge", when Teal'c explains that he has always had faith in their ultimate triumph over the Ori, Mitchell remarks that with that mentality he is probably unconcerned with their current danger and already thinking about what they are going to watch for movie night. Teal'c responds that he was considering Old School.
    • Lampshaded and inverted in the episode "Bad Guys" when our heroes are pretending to be, well, the bad guys.
      (two women are arguing over a man)
      Daniel: What the hell are you doing?! Stop it!
      Hesellven: She started it.
      Sylvana: Oh. I think you started it when you kissed Harron.
      Daniel: Shut up. Shut up! You're hostages! This is like a, a life-and-death situation here. Start acting like it.
      Sylvana: Oh, please. You're not rebels. We're not deaf, you know, everyone in this room knows it.
      Daniel: That doesn't matter. You're hostages, we're... we're your captors. We're heavily armed. There's uh... there's rules, there's a whole school of etiquette to this. (pause) Don't eyeball me.
  • Catchphrase: Many of them:
    • Teal'c: "Indeed."
    • Jack O'Neill: "Ah, fer cryin' out loud!" — "Ya think?" — "You have GOT to be kidding me!" — "O'Neill. With two L's." — "Magnets."
    • Cameron Mitchell: "Like my grandma always said, [insert proverb or adage here]." — "That's what I'm talking about!"
    • Daniel Jackson: "We're peaceful explorers, and we come from a planet called Earth." — "Hear me out..."
    • Sam Carter: "With all due respect, sir..." and when positing a logical but probably incorrect guess, "I don't think so."
    • Jonas Quinn: "This is my first [whatever]."
    • Walter Harriman (and other gateroom technicians): "Chevron seven... locked."invoked
    • Rebel Jaffa: "I die free!"
    • The Ori followers: "Hallowed are the Ori."
    • This exchange happens quite often between Jack and Daniel and is flippable:
      Jack: Daniel?
      Daniel: Jack?
  • Cat Fight: "Avenger 2.0" closes with Carter in a fight with Dr. Jay Felger's assistant over who gets his affections... before Felger snaps out of it.
  • Celebrity Resemblance: Actors Michael Shanks and Ben Browder got a lot of attention after the latter was added to the cast, due to their reported visual similarity. When Vala Mal Doran met the two of them at once, she commented that Earth has a "somewhat limited gene pool."
  • Chain of Deals: "The Ties That Bind" has SG-1 and Vala go through one to get a scientist to remove a bond created between Vala and Daniel by a weird phlebotinum interaction.
  • Characterization Marches On: When he is introduced in "Summit", Ba'al is described as a ruthless, sore loser who once wiped out two star systems rather than lose them to Cronus. This is quite different from the Affably Evil Magnificent Bastard of the last couple seasons.
  • Chekhov's Armoury: Everyone they meet. Everything they find. Everything they bring back. Everything they do to their Stargate (beyond simple dialing... and even so). Even the Engaging Chevronsinvoked is a plot point in some episodes (because it is so slow).
  • Chekhov's Gunman:
    • In the beginning of "Wormhole X-Treme!", Martin gets into an argument with the "Prop guy" over which fruit to use for an alien setting. The same prop master later guides Martin to where the actual alien device is being used on the set and is revealed to be an agent of the NID.
    • When Mitchell is held captive by the Sodan in "Babylon" he briefly sees, but does not speak or interact with, the Prior that has come to convert them to Origin. In "The Fourth Horsemen", that Prior is revealed to be the source of the plague that is ravaging the Earth, and might also be the key to its cure.
  • Chekhov's Lecture: In "The Warrior", K'tano attempts to address O'Neill's objections to the way he runs the Jaffa Rebellion by explaining the rite of joma secu, whereby any Jaffa has the right to challenge K'tano for leadership if he is dissatisfied. After Lord Yu reveals to Teal'c that K'tano is really trying to help the System Lords eliminate all the rebel Jaffa at once, Teal'c challenges K'tano, who turns out to actually be the Goa'uld Imhotep.
  • Chick Magnet: It seems that every other female character will try to get into Daniel's pants at some point. Lampshaded in an early episode when O'Neill says at this rate, Daniel is going to have a girl on every planet.
  • Child by Rape: Shifu is conceived when Apophis and Amaunet mate with each other using their hosts — who obviously have no say in the matter.
  • Childless Dystopia: The Aschen Confederation offered the people of the planet Volia (P3A-194) a cure for a terrible disease on their world. However, the vaccine also resulted in sterility; the once thriving world of millions was reduced to chaos and riots, and then to a peaceful but empty world, with a few thousand apathetic residents and automated machines tending farmland. An earlier episode portrayed a Bad Future in which the same race was in the process of doing this to Earth.
  • The Chosen Zero: The Asgard ask SG-1 for help defeating the Replicators, because despite all of their intelligence they have yet to figure a way to defeat them. Earthlings, even though they are far less technologically advanced, have an ability to "think outside the box" that has allowed them to defeat the Replicators several times. Daniel summarizes this:
    Daniel: Let me get this straight, you need someone dumber than you?
    Jack: I think we can help you with that.
  • Clingy MacGuffin:
    • The Atoniek Armbands.
    • The bracelets brought by Vala at the start of season 9. Dr. Lee's best suggestion to remove them was to process with a surgical amputation followed by re-attachment of the hand...
  • Clip Show: Done once a season. Except for season two's "Out of Mind" and season eight's "Citizen Joe", each clip show advanced the plot of the series, sometimes radically, by framing the clips as the Stargate Program being introduced and explained to people who had previously not known its details. This format was used to reveal the Stargate program to the United Nations Security Council in season six and a new incoming United States President in season seven. Like everything else on the show, parodied in "200".
  • Clone Degeneration:
    • The Asgard are a dying race because they have lost the ability to reproduce sexually and their cloning technology is sufficiently imperfect that entropy must inevitably win.
    • The teenage clone O'Neill was a victim of genetic degradation because Loki had been sloppy and irresponsible in the cloning procedure.
  • Cloning Blues:
    • Played with in "Tin Man". Clone!Jack plays it straight, Clone!Daniel and Clone!Sam invert it by being so fascinated they debate the meaning of life and discuss the mechanics of it with their originals, and Clone!Teal'c averts it as he does not talk at all.
    • In "Fragile Balance", Teen!O'Neill does not handle the realization that he is a (dying) clone very well.
  • Close Enough Timeline: "Moebius" ends with the revelation that there are now fish in Jack O'Neill's pond, whereas it had previously been completely devoid of fish. Word of God has fluctuated back and forth as to whether or not this really was a different timeline, or if Jack had just been exaggerating when he had previously said his pond had no fish at all.
  • Closet Geek: Teal'c, surprisingly enough. Among his favourite films is Star Wars (he's seen it 9 times, and when asked for an example of a virgin birth, he immediately thinks of Darth Vader), and he mentions having played video games like Def Jam Vendetta.
  • Clothing Damage:
    • Jack wears the same outfit throughout "Abyss", and as the episode progresses there are more numerous holes and burn scars in his clothing after each torture session.
    • In "The Other Guys", Felger and Coombs disguise themselves as Jaffa by taking the armor off a pair of executed Free Jaffa. Both their sets of armor have staff blast holes from when their former wearers were killed, which they awkwardly try to cover.
  • Cold Equation: In "Tangent", Teal'c and O'Neill are Almost Out of Oxygen and expect rescue in twenty-four hours, twelve hours after they will have died from CO2 poisoning. They recognize that if there was only one person left they might survive to rescue, and Teal'c puts himself in a deep meditation to stretch out their air supply.
  • Collapsible Helmet:
    • Not as fancy as in the movie, but they appear in "Children of the Gods" with Apophis and the Serpent guards.
    • The Horus Guards have the same helmets as seen in the movie, but effect limitations meant that the actual collapse was usally hidden behind a cut. It was preserved in two episodes: Season two's "Secrets" and season eight's "Moebius".
  • Colonel Badass: SG-1 has one Colonel and two Lieutenant Colonels in its roster throughout the series, and all are sufficiently badass. Even the Colonel who was only on the team for a single episode, and was revealed as a mole, formerly named a trope.
  • Colony Drop: In "Fail Safe" Anubis tries to hit Earth with a planet-killing asteroid. He used one with a naquadah core, just in case Earth tried to use a bomb to divert it, in which case we'd be subject to an Earth-Shattering Kaboom. SG-1 ends up using a tel'tak's hyperdrive to jump it through Earth.
  • Comes Great Responsibility: The complete phrase is quoted verbatim when it is written on the Atoniek armbands, which grant their wearer extreme strength, speed and senses.
  • Come with Me If You Want to Live: Inverted in the season 5 episode "Desperate Measures". Colonel Frank Simmons says this word-for-word to the Goa'uld possessing Adrian Conrad — after having put a couple of bullets from behind into Colonel O'Neill.
  • Commuting on a Bus:
    • Hammond was promoted to lieutenant general at the start of season 8 and posted to the Pentagon in charge of Homeworld Command. He made a guest appearance in "Prometheus Unbound" (and took his chair with him back to the Pentagon). He made several more guest appearances, including one on Stargate Atlantis and another in Stargate Continuum.
    • O'Neill was promoted to brigadier general at the start of season 8 so his onscreen time could be significantly reduced, reflecting Richard Dean Anderson's desire to spend more time with his family. In season 9 he left the show's main cast to replace Hammond as head of Homeworld Command, and made several guest appearances after that.
  • Compensating for Something: Vala accuses the chairman of the senate appropriations committee of wanting to build more Daedalus-class ships because he is compensating for his own shortcomings.
  • The Computer Is a Cheating Bastard:
    • O'Neill's simulation in "The Gamekeeper", which recreates a mission of his in East Germany that turned horribly bloody. Each time O'Neill prevents a problem that arose in the real mission, the computer creates a new problem to impede progress.
    • This simulator reappears in "Avatar" when the SGC tried to use it for VR training. It quite blatantly cheats when Teal'c is plugged in; it changes the rules of the game during play.
  • Conflict Killer: Season eight's "Reckoning" saw the commencement of the full-scale war between the rebel Jaffa and the Goa'uld, initiated by a series of surprise attacks on key Goa'uld facilities, only for the Replicators to attack the Milky Way and force the Goa'uld, Jaffa, Tok'ra and Tau'ri to work together.
  • Con Lang: Goa'uld, the language of the Goa'uld, Tok'ra, Jaffa and majority of the humans of the Milky Way. The language uses a subject-verb-object grammatical structure, but with a much simplified tense formation compared to English. The language has multiple writing systems, based on various ancient Earth writing systems (including Egyptian hieroglyphs and Linear-A), but most written Goa'uld seen on the show is a simple letter substitution, as opposed to actually being written in the language. The word "goa'uld" itself translates to English either as "gods" or "children of the gods"; its usage varies.
  • Conspiracy Theorist: Martin Lloyd in the episode "Point of No Return".
  • Contagious A.I.: Central to a single episode; it can transmit itself by radio, and even infect people.
  • Continuity Nod:
    • In "Message in a Bottle", Carter remarks that the artifact they found has been emanating an energy signature since Neanderthals were a dominant species on Earth. Jack replies, "Ah, takes me back...", referencing the episode "Broca Divide", where O'Neill was turned into a cave-man on an alien planet.
    • This conversation in season seven's "Fragile Balance":
      Hammond: Are you saying Colonel O'Neill has, somehow, regressed more than 30 years overnight?
      Daniel: Stranger things have happened.
      Teal'c: Name but one.
      Daniel: Well, there was the time he got really old, the time he turned into a caveman, the time we all swapped bodies...
    • The episode "Heroes", though not a Clip Show, features the characters reviewing and explaining their adventures through the Stargate up to that point in time. They make reference to important events in the lives of each character throughout the series, including events which they have agreed never to talk about again.
    • In "Moebius, Part 2", McKay attempts to justify the callsign "Gateship One" to General Hammond. This is a reference to the pilot episode of Stargate Atlantis, where he makes the same attempted justification to Dr. Weir.
    • In "Ripple Effect", Colonel Mitchell (one of them) mentions multiple situations where personnel of the SGC believe they have returned to Earth, only to learn they are being manipulated by aliens. He goes over the events of "Out of Mind" in season two, and the episode "Home" from season one of Stargate Atlantis.
    • In "Arthur's Mantle", Colonel Mitchell briefly runs through the various "alternates" that SG-1 has been through:
      Mitchell: ... that was alternate realities, this is alternate dimensions, all I need is a good time-travel adventure and I'll have scored the SG-1 trifecta!
    • When Daniel finally manages to travel to Atlantis in "The Pegasus Project", Vala remarks that his previous failures to get to the city were only her fault twice. Her first two appearances, "Prometheus Unbound" and "Avalon", both had her interfering with Daniel's plan to travel to Atlantis aboard one of the Earth's relief ships.
  • Convenient Replacement Character: Jonas' arrival and departure from the team coincide perfectly with Daniel's departure and return.
  • Converging Stream Weapon:
    • The AG-3 satellites array firing on Moscow (virtually) in "Absolute Power".
    • The weapon made out of the six Eyes that Anubis uses on Abydos, in "Full Circle".
  • Conversational Troping:
    • In "Orpheus" Sam picks apart the poor planning of the aliens in Signs.
    • In "200" she calls Wormhole X-Treme! creator Martin Lloyd on a particularly absurd use of Unrealistic Black Hole.
  • Cool, but Inefficient: Seems to be the central Goa'uld design philosophy. Lampshaded several times.
    O'Neill: This [staff weapon] is a weapon of terror; it's made to intimidate the enemy. This [P90] is a weapon of war; it's made to kill your enemy.
    • Ring transporters when compared to the Asgard's beaming technology.
  • Cool Chair: General Hammond's chair. Everyone loves to sit in it, declaring it to be the best chair. Hammond went so far as to take the chair with him when he left the SGC.
  • Cool Gate: The SGC's Stargate provides the page picture.
  • Cool Old Guy: Hammond, Landry, Bra'tac and Jacob Carter.
  • Cool Starship:
    • The Ha'tak, Goa'uld pyramid ships, remain present and powerful throughout the entire series.
    • Ori ships: they are big, beautiful, practically invincible, and can one-shot Ha'taks.
    • The BC-303 Prometheus was kind of cool, being the first human starship and the workhorse for humanity for three seasons. Then they introduced the BC-304 Odyssey and Daedalus ships, which are just awesome.
    • Also, the F-302 fighters.
    • Asgard O'Neill-class ships.
  • The Coroner Doth Protest Too Much: Gerak's predecessor as the leader of the Free Jaffa that formerly served Ba'al, who was an ally of Bra'tac and supported the foundation of a democratic government, mysteriously disappeared four months before the start of season nine. Though no evidence linking Gerak to the disappearance has been discovered, and foul play was never definitively established at all, Teal'c and General Landry consider it more than just good fortune for Gerak.
  • Cosmopolitan Council: The Goa'uld, whose hosts are male, female, Caucasian, Black, Asian and various combinations thereof. Does not make them any less evil, though. Also counts as an aversion, since once you get under the skin, the symbiotes (e.g. the actual Goa'uld) are all the same species and gender (we never see if there are any differences among them equivalent to skin color).
  • Could Say It But:
    • In "Ascension", when Carter is trying to figure out how to deal with Orlin, who has shown that he will remain invisible if her superiors come looking for him, she approaches O'Neill with a "hypothetical" question about what to do in this situation and how, hypothetically, he might order her to proceed.
    • In season eights "New Order", when Dr. Weir explains why the SGC has remained closed during international negotiations, Daniel Jackson reads through her political phrasing and deduces that the government is using the Stargate as a bargaining tool with other countries, to which Weir replies, "I would never say that." Later in the episode, when Carter is asking to be allowed to take their Ancient-modified Goa'uld cargo ship in the hopes of contacting the Asgard to save O'Neill, she points out that Earth might never figure out how the ship was modified. Dr. Weir asks if Carter is saying that she, the person most likely to figure it out, will deliberately refuse to help if her request is not granted, to which Carter responds, "I would never say that."
  • Courtroom Episode: "Cor-Ai"; "Pretense"
  • Crazy Enough to Work:
    • SG-1 has racked up a fair number of wins with good old-fashioned tenacity and copious amounts of firepower. However, their best work usually involves doing things that sound flatly ridiculous, even to themselves.
    • Lampshaded in "Small Victories" by Thor, who had enlisted SG-1's help for exactly this reason.
      Thor: It was your stupid idea, Major Carter.
    • Lampshaded in "Fallen" where, after Carter outlines her plan, O'Neill asks everyone who thinks it is an insane plan to raise their hands. The whole room does... including Carter.
      Hammond: Keep those hands up, people. Because the next question is: who's going to make this happen?
  • Crazy-Prepared: By the end of the series, the SGC has contingencies in place to deal with practically anything. One that gets repeated is that, due to having been temporarily stranded several times with no DHD to dial the gate, after getting the specs for a miniature naquadah reactor the first thing we see created is a portable version meant for just that eventuality. (As long as you have a source of energy for the naquadah in the gate to absorb, you can dial out by rotating the ring manually.)
  • Creepy Child: Adria, Vala's daughter. Although as the Orici created by the Ori, she doesn't stay a child for long..
  • Critical Staffing Shortage: It has several occasions where the main cast happens upon an abandoned facility and most get it operational enough to complete whatever the objective is.
  • Cruel and Unusual Death: Apparently, the Goa'uld Marduk was so evil that his own priests did a Heel-Face Turn and sealed him in a healing Sarcophagus... together with a nasty little critter that would continuously devour his body while said Sarcophagus would heal and resurrect him. As O'Neill succinctly put it, that is officially the worst way to go.
  • Cruel Mercy: In the episode "Threads", it seems like Anubis will execute his minion Ba'al for betraying him and failing to defend Dakara from the System Lord's enemies. Even Ba'al thought Anubis' plan to wipe out all life in the galaxy at once was a tad overkill, if only out of self-preservation. However, Anubis lets Ba'al live solely so he can witness the coming end of all life, himself included, knowing that his work on the Stargate network made it possible.
  • Cryptic Conversation: Oma Desala and the nameless monk of "Maternal Instinct" speak frequently in Zen koans when guiding others towards Ascension. Daniel sometimes follows along, but often remarks on the confusing nature of these conversations.
    "If you immediately know the candle is fire, then the meal was cooked a long time ago."
  • Crystal Skull: In "Crystal Skull".
  • Cultural Posturing:
    • Jack, whenever he's forced to work with the Russians.
    • Daniel does this briefly in "Watergate", lampshading that he's clearly spent too much time around Jack.
  • Culture Clash: Teal'c's alien background occasionally deviates from what is expected amongst American society. When he encounters Colonel Maybourne in "Touchstone", he explains that on Chulak Maybourne's past actions would allow Teal'c to dismember him, and in "Affinity" he explains that if a Jaffa couple in a relationship cannot agree on a "pledge break", then a weapon is required to resolve the dispute.
  • Cunning Linguist: Daniel Jackson
  • Curbstomp Battle: The Battle of P3Y-229.
  • Cure For Cancer: The Goa'uld and Tok'ra symbiotes can act as this.
    Garshaw: We cure it all the time, it's no problem.
  • Curse Cut Short:
    • In "Secrets", the reporter gets out "son of a bi—" before expiring after being hit by a car.
    • When Jonas Quinn asks Carter to talk to a woman for him, making up a story about how it is a Kelownan tradition for a friend to gauge interest, she calls him a "chicken sh—" before being interrupted.
    • In "Moebius", when SG-1 gets taken out by a Jaffa grenade.
  • Curse of Babel: In "The Fifth Race" and "Lost City", O'Neill downloads an Ancient database into his brain (accidentally the first time, intentionally the second). His brain is gradually reprogrammed and he goes from being able to speak English to speaking Ancient.
  • Cyanide Pill: Carried by all the Russians teams when they were operating their own gate program.
  • Cycle of Revenge: The nations of Rand and Caledonia finally had their long-expected war in "Icon", and are (slowly) rebuilding in the sequel episode, "Ethon". Unfortunately, both governments seem to be heading right back to war; Jared Kane, a senator of the Rand Protectorate, enlists the help of the SGC to derail the coming conflict. When his government demands to know why he is helping the enemy, Kane explains that he has no love for Caledonia, but he just does not want to see countless more people die (on either side) re-righting wars that were started by their fathers and their father's fathers. Things didn't pan out, unfortunately, and when SGC was able to get a ship out there to check on them, they seemed pretty sure that nearly the entire population was killed in a massive war.

    D 
  • Dance Battler: Any practitioner of the Jaffa martial art Mastaba (seen most prominently in "The Warrior"). In Real Life, it's called capoeira: the show hired some professional instructors for the episode when they needed a Jaffa martial art and thought capoeira was cool.
  • Dangerously Genre Savvy: Some Goa'uld get this way in the later seasons. For example, "Fail Safe" has Anubis try to destroy Earth by dropping an asteroid on it. However, he also picked an asteroid with a naquadah core, so that if the cast nukes it (which is exactly the solution they come up with), the resulting explosion will still destroy the Earth.
  • Dangerous Phlebotinum Interaction: "Singularity" shows that in addition to the main way naquadah is explosive, it reacts explosively with an alloy of iron and potassium (we're talking two microscopic amounts of each obliterating a whole room, including the camera on the other side of it), a fact used by Nirrti to turn a girl into a walking weapon of mass destruction.
  • Dare to Be Badass: Ironically given to a (up to that point) villain, when Mr. Woolsey first begins to recognize that his superiors are not as honorable as himself.
    Chairman of the Joint Chiefs of Staff: You're a resourceful man Mr. Woolsey. If you think there's proof out there, find it.
  • Dark Age Europe: In the first season, when the show was still getting its footing and trying to explain why other human-populated planets, particularly the Tollan, had more advanced technology than Earth, Daniel explained that the Dark Ages held back our own technological advancement for several centuries. This idea was dropped soon after, since it has little real-world backing and is rooted in a European-centrist philosophy, which disregards scientific advancement from outside "the West". Later episodes would explain the technological disparity with in-universe rationales; including contact with other advanced races, the development of a single key technology that accelerated their progress, or even just the random vagaries of chance.
  • Data Crystal: Used by most spacefaring peoples. Like many other technologies, it comes from the Ancients and was widely copied.
  • Daydream Surprise:
    • Dr. Jay Felger is prone to them, as both of his episodes end with a fantasy segue. "The Other Guys" closes with both him and Coombs being awarded medals, before Carter begins to make out with Felger upon the dais. "Avenger 2.0" closes with him and his assistant making out before Carter comes in and engages his assistant in a Cat Fight over his affections.
    • In the episode "Grace" Carter has repeated hallucinations of her friends and family, several appear (and might be, or might not be) real.
  • Dead Alternate Counterpart: The series did this in some form for nearly every alternate universe they ran across.
    • "There But for the Grace of God": The alternate Daniel Jackson never joined the Stargate Program and died in a Goa'uld orbital bombardment of Egypt. Alt!Hammond subsequently died defending the SGC, Alt!O'Neill was killed trying to talk Alt!Teal'c into a Mook-Face Turn, and Alt!Carter blew herself up to keep a piece of phlebotinum out of Goa'uld hands. Alt!Teal'c died when the base self-destructed.
    • "Point of View": The alternate Jack O'Neill was killed in action defending his SGC from a Goa'uld ground offensive, and Alt!Teal'c died when Prime!Teal'c shot him. Inverted with Maj. Charles Kawalsky, who was alive in the alternate universe but dead in the prime timeline. We also see several alternate universes where the Goa'uld were patrolling the SGC; presumably none of the cast survived.
    • "Moebius": Played with to hell and gone. The original SG-1 except for Daniel gets killed by Ra's forces, creating an Alternate Timeline where Ra took the Giza gate with him when he left Earth. Alt!Kawalsky is killed in action on Chulak. Alt!Teal'c is forced to kill Alt!Daniel after Apophis has him implanted with a symbiote. Prime!Daniel, Alt!Sam, Alt!Teal'c, and Alt!Jack presumably die of old age in ancient Egypt. It's a very weird episode.
    • "Ripple Effect": Inverted. Among the alternate SG-1's that showed up we had at least two characters who were dead in the prime timeline: Martouf, a Tok'ra operative who died in "Divide and Conquer," and Maj. Dr. Janet Fraiser, who was killed by a stray staff blast in "Heroes, Part 2."
  • Dead Girl Junior: Janet Wells
  • The Dead Have Names: Inverted at the memorial service at the end of "Heroes". During the eulogy, Carter mentions the names of everybody who is alive thanks to the work of Janet Fraiser.
  • Deadpan Snarker: Jack O'Neill, with Daniel Jackson occasionally getting into the act; the latter mentions, after annoying a Russian officer, that he has been spending too much time with Jack. People meeting Jack for the first time will sometimes ask the question, "Is he always like this?"
    Ba'al: You dare mock me?
    O'Neill: Ba'al, come on, you should know me by now. Of course I dare mock you.
  • Death by Pragmatism: On occasion.
  • Death Glare: Teal'c has managed to break the resistance of prisoners and intimidate aliens simply by the strength of his look.
  • Death Is Cheap:
    • Every team member died at least once and got better, but it happened to Daniel Jackson so many times -- between 6 and 22 times over the course of the show, depending on whether you count presumed deaths, alternate realities/timelines, All Just a Dream episodes, expanded universe audio dramas, etc. — that it became one of the series' Running Gags. At one point, when the last place they know Daniel was happened to be a replicator ship which fell apart in deep space — and when the audience saw him stabbed in the chest just before that — Carter's request for some kind of memorial service was met with O'Neill saying Jackson was going to be back by the end of the day, and was probably just waiting for them to say nice things about him before he showed up. Consider this scene where two Mauve Shirts are exploring an archeological site on another planet:
      Balinsky: Dr. Jackson's going to die when he sees this!
      Dixon: Again?
    • Thor, and by extension all the Asgard, are effectively immortal since they transfer their minds to a new cloned body in the event that their current body is destroyed or lost. Thor dies twice throughout the series, only to return later with a new body. Fittingly, he is voiced by Michael Shanks, Daniel Jackson's actor.
    • In the episode "Abyss", Jack is tortured to death several times by Ba'al, only to be resurrected in a sarcophagus so Ba'al can start over again.
    • Apophis is one character whose number of deaths rival Daniel Jackson, as he has been presumed dead (and actually dead) so many times that, when he was finally Killed Off for Real, Jack corrected himself from "100% sure" down to "99% sure". Despite being Killed Off for Real, he was brought back multiple times in alternate realities and dreams/hallucinations.
  • Death of a Thousand Cuts:
    • Ba'al tortures Jack in "Abyss" through the slow application of small drops of acid.
    • Mentioned by name by Daniel Jackson in the episode "Avatar".
  • Delivery Guy: Daniel Jackson in "Brief Candle", where the team stumbles upon a woman giving birth in an empty temple, and again in "Secrets", when Sha're, Goa'uld-infested and heavily pregnant with Apophis' child, goes into labor.
  • Department of Redundancy Department:
    • O'Neill gives Lieutenant Satterfield, a trainee hoping to join the SGC, "high marks for her high marks."
    • O'Neill gets a bit meta with it when one of the Prometheus's systems burns out in "Memento".
      Colonel Ronson: There's no redundancy for that particular system.
      O'Neill: So you're saying there's no redundancy.
  • Depleted Phlebotinum Shells: Besides naquadah-enhanced nukes (see the main Stargate Verse page), the SGC has been known to use trinium tranquilizer darts (unsuccessfully) against Kull warrors, and later an energy weapon reverse-engineered from the Ancient phlebotinum that gave life to the Kull.
  • Descending Ceiling: Part of the test of wisdom in Merlin's chamber at Avalon.
  • Description Cut: In "Cure", regarding O'Neill.
  • Destructive Saviour: The Tok'ra see the Tau'ri this way.
  • Determinator:
    • In "Ethon", when Kane asks if Daniel Jackson ever gives up, he says that he does not give up until he is dead, and sometimes not even then.
    • Teal'c manages to fight, defeat and execute Arkad after having been shot twice before the fight even began and being beaten and gutted during the struggle.
  • Development Gag: The ending of "200", where the Wormhole X-Treme! movie production is cancelled in favor of renewing the TV series, reflects the actual status of SG-1 during production of seasons five, six and seven, where the intention was to end the series after each season and conclude the story with a movie. However, the show kept getting renewed instead, and the plan for the movie was eventually scrapped and turned into the season seven finale "Lost City".
  • Diabolus ex Machina: The combat simulator chair in "Avatar" does this repeatedly because of its intelligent programming.
  • Did I Just Say That Out Loud?:
    • O'Neill will only allow a Russian officer to join SG-1 over "[his] rotting corpse," to which he then amends, "Did I say that out loud?"
    • When President Hayes is made aware of the Stargate, and Vice-President Kinsey's association with the project, he begins to wonder about some of the campaign financing that Kinsey had brought to their election. When the Chairman of the Joint Chiefs of Staff reacts to his statement, he smirks and responds, "Did I say that out loud?"
  • Die Hard on an X: "Bad Guys" places SG-1 in the role of the villains, accidentally taking a museum hostage on an alien planet when they are mistaken for rebels. When a security guard manages to avoid being captured and later tries to foil their "evil plan", Mitchell refers to him as "John McClane", which Daniel does not understand, so Teal'c explains that he is referring to the movie.
  • Digging Yourself Deeper: When Vala is being reviewed for suitability to formally join the SGC, she is given a polygraph. Vala tries for some generic small talk and compliments the doctor administering the test, only for the polygraph to flash and indicate that she is lying. After each flash she tries to amend her statement, lowering the compliment each time, until she finally says that the doctor looks "not offensive".
  • Dirty Coward:
    • Colonel Samuels, an NID-affiliated officer, smugly presents his "Goa'uld buster" weapons as the key to defeating Apophis' attack on Earth in "The Serpent's Lair". When the attack fails to have any appreciable affect, and his subsequent suggestion to send a nuclear weapon to Chulak is overruled as being pointless, he requests to evacuate to the Alpha Site. General Hammond seems to almost take glee in denying his request, explaining that the idea was to send the best and brightest — and Samuels does not qualify.
    • Robert Kinsey attempts to flee Earth to the Alpha Site as soon as Anubis launches his attack, despite learning that President Hayes is staying at the White House, and visibly panics when Anubis tries to send a bomb through the gate to the SGC.
  • Disastrous Demonstration:
    • In "Tangent" Jack and Teal'c demo the X-301, a prototype Space Fighter created from a pair of death gliders swiped by SG-1 in "The Serpent's Lair." Neither they nor the engineering team were aware of a recall device Apophis had installed in his gliders after Teal'c's defection, and the ship locks them out of the controls and sets a sublight course for Chulak.
    • Downplayed/played for laughs in "Avenger 2.0" with Doctor Felger's prototype plasma cannon. The thing shorts out spectacularly and trips circuit breakers all over the base. Later in the episode his attempt to create a DHD-disabling computer virus results in the entire Stargate network reconfiguring itself, but it's subverted as it turns out that Ba'al had reverse-engineered the virus and altered it so it would spread throughout the network via the DHDs' automatic updates.
    • Used purposely in "Bounty". Dr. Lee and Colonel Carter reveal that, in order to pretend there's a development process involved with the alien technology they swipe, the scientists regularly do presentations where they induce flaws in the technology to produce this effect.
  • Discard and Draw: The Prometheus is destroyed, leaving Earth without one of its strongest weapons... and is promptly replaced with the more advanced Odyssey in the very next episode.
  • Discontinuity Nod: See also Canon Discontinuity.
    • The first season episode "Hathor" was widely disliked by fans and, though the Hathor character did reappear, the specific details of the episode were never revisited. In follow-up episodes, whenever the events were discussed one of the characters would comment that they had agreed never to talk about that again.
    • In "Wormhole X-Treme!", the on-set director of the Show Within a Show referred to Martin's suggestion of "three shots disintegrates" as the stupidest thing he had ever heard. The ability of zats to disintegrate a body with three shots had been dropped in season three.
  • Discriminate and Switch:
    • In the pilot, Carter mistakes O'Neill's dislike of having her assigned to his team as a feeling that, as a woman, she will be a liability. O'Neill explained that his problems had nothing to do with her being a woman, he likes women, his problem is that she is a scientist. The conversation, including the infamous "reproductive organs" line, was edited down when the pilot was re-released as a Direct-to-DVD film in 2009.
    • Inverted in "The Other Side". The Eurondans are extremely uncomfortable around Teal'c, with the implication that it is because he is a Jaffa. However, it later turns it that their discomfort was because Teal'c is black and that they are their planet's equivalent of White Supremacists, responsible for launching the current global war in their attempt to ethnically cleanse those they deemed impure.
  • Dispense With The Pleasantries:
    • Inverted in one episode, when Daniel (who has at this point Ascended to a Higher Plane of Existence) shows up again, and O'Neill immediately asks him what's wrong. Daniel gets upset because O'Neill didn't even bother with such basic pleasantries as saying hello to him first.
    • O'Neill inverts it himself at another point, when Jacob comes through the Stargate:
      O'Neill: Jacob!
      Jacob: Jack, we've got a problem. We need to talk.
      O'Neill: Hi! Hello. How are ya? Long time, no see. What's doing? What's up? Hey, buddy!
      Jacob: I'm sorry, Jack. It's good to see you again. Congratulations on your promotion.
      O'Neill: Thanks.
      Jacob: You deserve it.
      O'Neill: Yes. Well... What's up?
      Jacob: The Replicators. They've launched an all-out attack on the Goa'uld. If the Goa'uld can't find a way to stop them, the Replicators will easily overrun our galaxy, in a matter of weeks.
      O'Neill: Why didn't you say so?
      (Jacob gives O'Neill a look and walks off)
      O'Neill: (after a pause, hurrying after Jacob) I'm sorry. You said we have a problem, not a big galactic emergency.
  • Distracted by the Sexy:
    • In "Upgrades", O'Neill goes on a tear about the Tok'ra and his dislike of them, only to trail off when Anise steps through the gate.
    • In the season 10 episode "Family Ties", Sergeant Siler slams into an open door after being distracted by Vala and Sam in civilian clothes.
  • Ditto Aliens: All the Asgard are portrayed by the same puppet, and O'Neill often needs to be prodded to recognize one of them as Thor. Carter, however, seems have no trouble at all identifying different Asgard by sight.
  • Divided We Fall: The Jaffa rebellion was severely hampered throughout its existence by the inability of the separate factions to coordinate and work together. There was at least one outright betrayal in "Avenger 2.0", and "Sacrifices" highlighted the disparate goals of each individual faction.
  • Doctor Doctor Doctor:
    • In "Tangent", Major Davis introduces General Vedrine to SG-1 and each is greeted with their salutation (Colonel, Major and Doctor), each responding with "General."
    • The episode "Frozen" has Dr. Fraiser being introduced to the Antarctic team, leading to a chorus of "doctor"s (and a few "Majors" thrown in for Carter) before O'Neill interrupts and tells them that's enough.
  • Documentary Episode: The two-part episode "Heroes", which features Emmett Bregman filming a project on the SGC and its personnel at the direction of the outgoing US President. This includes interviews with the primary cast and several of the recurring supporting characters, discussions of past events, and debates on whether or not the program should be kept secret from the public. Scenes from the documentary are filmed with different lighting and staging to reflect the presence of an in-show camera.
  • Does Not Know His Own Strength: When SG-1 puts on the Atoniek armbands, which grants them super strength, speed and senses, Jack O'Neill seems to have a lot of trouble adjusting. When it first takes effect, he manages to knock Teal'c unconscious in a boxing ring. Later, he accidentally knocks out part of Hammond's concrete wall to demonstrate what they can do and, afterwards, accidentally hospitalizes Sergeant Siler when he knocks him down a flight of stairs.
  • Don't Call Me Sir: Emmett Bregman, shooting a documentary of the SGC, repeatedly tells the colonel of Cheyenne Mountain public relations to call him Emmett, to which the colonel always responds "Yes, sir."
  • The Door Slams You:
  • Double Caper / Gambit Pileup: In "Ripple Effect", the alternate SG-1's plot to steal the Atlantis ZPM is quickly foiled due to the team figuring out that Mitchell would be replaced by his doppleganger when he went to speak to him. As such, despite their doppleganger's planning a trap for them when they'd inevitably escape the brig, they failed to anticipate the team being Genre Savvy themselves and spring their own.
  • Double Standard: The way the members of the SGC treat other life-forms tends to be this. They will be compassionate and understanding with all humans and any creature that is bipedal (or not too far from human), and yet treat any form of artificial intelligence or any biological creature that is too alien as a threat or "not really alive." In the case of artificial intelligence, they attribute their actions to their programming, not their psychological make-up and free-will, even with artificial life-forms who are as complex and sentient as human beings.
  • Double Standard: Rape, Sci-Fi: Thoroughly averted.
    • In "Hathor", after everything's sorted out, everyone at the SGC is visibly disgusted at what the title character did to Daniel. This includes the writers, who considered "Hathor" the worst episode in the series: in later episodes the characters refuse to talk about it and that aspect of Goa'uld reproduction was quietly retconned away.
    • Likewise, when the Goa'uld-infested Sha're turns up nine months pregnant in "Secrets", she's very ashamed and worried Daniel hates her.
      Daniel: No. I hate what's been done to you.
  • Dramatic Irony: Some of the friction between Captain Carter and her father stems from what he considers to be her abandonment of her dream of going into space and her wasting her potential working in Cheyenne mountain; he pulls strings to have her transferred to NASA, which she rejects. If only he knew that she was going into space on a daily basis, farther than any NASA shuttle will ever go.
  • Dramatic Space Drifting: In one episode a bad guy gets beamed out into space for holding a gun on someone. When the former hostage asks what happened to him, he drifts towards the bridge window and actually gets a shot off before smacking into it and sliding off.
  • Dramatic Unmask: The ending of "Jolinar's Memories" has "Na'onak" pulling off his helmet to reveal that he was Apophis all along.
  • Dressing as the Enemy: Felger and Coombs disguise themselves as Jaffa in order to sneak around a Goa'uld base, all the while awkwardly trying to cover staff blast holes in the armor from when their former wearers were executed.
  • Driven to Suicide:
    • In "The Light"; Daniel and the members of SG-5 go through withdrawl after leaving a Goa'uld "opium den" (not actually about opium), and attempt to kill themselves. The episode opens with Lieutenant Barber running directly into the kawoosh of the opening Stargate.
    • When Jack accepts that Daniel cannot, or will not, use his Ascended powers to break him out of Ba'al's prison, he demands that Daniel at least kill him to keep him from being tortured and killed over and over again, and becomes enraged when Daniel refuses to do.
    • A literal example occurs in "Watergate", where due to being possessed by Water-based Aliens, the Russian team are forced to throw themselves through the Stargate and emerge on the other side, several hundred feet underwater.
  • Dropped a Bridge on Him: The Ori, who are maybe/maybe not destroyed 2/3 of the way through the final season, only to be declared dead five episodes later in the penultimate episode, thanks to the abrupt cancellation that cut the storyline short.
  • Due to the Dead:
    • In "Forever in a Day", an Abydonian funeral is witnessed. It draws heavily from Egyptian funerary rights, including the preservation of organs in canopic jars and weighing the deceased heart against a feather.
    • Jaffa funerals take place at night, with the body immolated on funeral pyre.
    • The Tok'ra have a funerary ritual involving the disintegration of their bodies in the vortex of an opening Stargate in order to prevent the Goa'uld from learning any information from their corpses or resurrecting them in a sarcophagus for interrogation. The eulogy points out that even in death they do not give in to the Goa'uld.
    • Part two of "Heroes" closes with a memorial service for Janet Fraiser with Major Carter giving the eulogy.
  • Dull Surprise:
    • The main cast criticized themselves for the ending to "Thor's Chariot", where they only seemed mildly intrigued by the sight of a ship the size of a city appearing and eliminating an entire Goa'uld army in seconds. In behind-the-scenes interviews, they explained that none of them appreciated just how impressive (or big) the ship would look in the finished episode, so they did not think to put more awe or fear into their expressions.
    • Invoked again by the cast about "Prometheus", where they likewise underestimated how impressive the Prometheus would be.
  • Dying as Yourself:
    • When Klorel is shot in "Within the Serpent's Grasp", Skaara briefly awakens and smiles at O'Neill. They do get resurrected later, but still.
    • When Amonet is killed by Teal'c, Sha're manages to break free a moment before death to tell Daniel that she loves him.
    • In "Serpent's Song", Apophis eventually succumbs to his injuries and dies, but his host lives long enough for Daniel to give him his last rites. Unfortunately for the host, Apophis is resurrected again.
  • Dying Race: The Asgard.
  • Dynamic Entry: In "Talion", Teal'c kidnaps Ba'kal by walking out of the shadows and knocking him out with a blow to the face.

    E 
  • Early-Installment Weirdness:
    • During Apophis' raid on earth, the earth soldiers manage to kill two jaffa, one of whom has a golden symbol on his forehead, the other of whom is a woman. The series would later use golden symbols exclusively to indicate a first prime, and make a point about jaffa culture preventing women from joining the military.
    • The later seasons definitively established that beings with naquadah in their bloodstream, including Jaffa, could "sense" other beings that likewise had naquadah in their blood, primarily Goa'uld (and Tok'ra) symbiotes. However, this was completely absent from the first season, and in "In the Line of Duty", the first episode to feature the ability, Teal'c never sensed the presence of Jolinar.
    • The Tollans' highly advanced technology that can't be reverse-engineered. Later episodes have the Tau'ri reverse-engineer several technologies from races even more advanced, and far more alien than the Tollan, who are just transplanted humans with a few hundred years more scientific progress than Earth. Really, the Tollan as a whole are weird. At one point, one of the Tollan mentions that quantum physics is essentially wrong. This is contrary to a lot of the technobabble used in the series afterwards. It seems the writers thought so too, because they get Killed Off for Real in season 5.
  • Earth All Along: In the season one episode "Solitudes", a glitch in the gate sends Carter and O'Neill to a strange ice planet, which turns out to be a surprise second gate in Antarctica.
  • Earth-Shattering Kaboom:
    • Several different Goa'uld take a crack at Earth, although Anubis nearly succeeds a couple times. But none of them top Major Samantha Carter using a Stargate to blow up a sun and wipe out a solar system, complete with (almost all of) Apophis' fleet.
    "You know, you blow up one sun and suddenly everyone expects you to walk on water!"
  • Easily Thwarted Alien Invasion: The episode "Politics" is about a Senator who believes that the Goa'uld are this, thus wants to cut SG-1's funding. He's not entirely wrong but underestimates the Goa'uld considerably since SG-1 keeps coming back alive. Destroying the Goa'uld by uploading a computer virus to their ship is sarcastically mentioned.
  • Eiffel Tower Effect: In the episode "1969", the team is travelling cross country and, at one point, the Willis Tower (formerly the Sears Tower) is shown to indicate they are in Chicago. Construction on the Sears Tower did not begin until 1971, two years after the setting of the episode.
  • Elaborate Underground Base: The SGC, one level beneath NORAD in the Cheyenne Mountain Air Force Station.
  • Elite Mooks: The Kull Warriors are part this, part Super Soldier, created by Anubis to replace the increasingly-rebellious Jaffa. They are completely artifical constructs, genetically engineered, super-tough, and virtually mindless. Although they all have a Goa'uld symbiote, those were spawned without the usual genetic memory, and thus lack any free will.
  • The Emperor: The Goa'uld were divided between a number of Evil Overlords with claims to godhood, but several aspired to control over the entire Goa'uld domain. Ra of the first movie was retconned to have been a symbolic Emperor who maintained the fiction of unity, with subsequent infighting breaking out among the other System Lords over his succession. Several come close, but Ba'al is the only one to outright claim to be the 'Sovereign of the Goa'uld Domain' in his near-victory.
  • The Empire: The Goa'uld Empire was an evil empire in name only (the "empire" part, they're a proudly evil bunch). Territorially it was the most powerful grouping in the Mily Way Galaxy, but in fact it is deeply fractioned between numerous regional System Lords who constantly fight each other for supremacy and after the death of The Emperor Ra in the original movie any semblence of unity is long gone. This initially worked in the humans' favor so they could focus on taking out each threat one by one, but frequently one of the Goa'uld would emerge victorious over the others to fill the Evil Power Vacuum and attack Earth directly.
  • Endless Daytime: In "The Broca Divide", the heroes visit a planet that is tidally locked. While the inhabitants of the "light side" have a Bronze Age culture bearing similarities to the Minoan civilization, the dark side is infected with a plague that turns people into savages.
  • Enemy Civil War: Happens all the time. The Goa'uld are feudal Always Chaotic Evil megalomaniacs by nature; the usual process is to fight among themselves until a top dog emerges (Ra, Apophis, Sokar, Apophis again, Ba'al, Anubis, Ba'al again...) then SG-1 wrecks the army of the top dog, and the cycle repeats itself. It's stated a few times in the series that the Goa'uld are actually doing more damage to their own forces than the puny Tau'ri; what Earth is really doing is continually upsetting the balance of power.
  • Enemy Mine:
    • Season seven has an episode titled "Enemy Mine" that refers to the movie by actually featuring a mine; the SGC must negotiate with the native Unas population for mining rights to a deposit of naquadah.
    • The SGC and the System Lord Yu coordinate their attacks against Anubis when it becomes clear that his advantage over the rest of the Goa'uld is too great, and the SGC then assists Ba'al with the same when Yu's senility makes his cooperation unpredictable.
    • The Tau'ri, Tok'ra and rebel Jaffa cooperate with the Goa'uld against the Replicators, who launch a full-scale invasion of the Milky Way in "Reckoning".
    • The Goa'uld Nerus proposed an alliance with the SGC in order to cooperate against the Ori, but he was working against them all along.
    • In "Crusade", Landry and Chekhov invoke this about the Stargate progam. While the Russians resent the Americans running the entire show and the Americans resent being heavily extorted by the Russians just to use the Gate, both sides consider it far better than letting the Chinese take control of the program.
  • Engaging Chevrons: invoked Trope Namer.
  • Entertainingly Wrong: In "Arthur's Mantle", Dr. Lee concludes that Sam and Cam were miniaturized, when actually they were sent into another dimension.
  • Epic Fail: As Dr. Felger explains, it probably took the Ancients thousands of years to build the Stargate network, and he managed to take it down in a day.
  • Even Evil Has Loved Ones:
    • Despite being Always Chaotic Evil, some of the Goa'uld actually seem quite fond of each other - for example, Apophis really seems to care for his wife, Amaunet, and son, Klorel. At the same time, however, Apophis doesn't seem to care about his brother Ra, using the latter's death as an opportunity to muscle in on his territory. He also has no qualms about killing Heru-ur, his own nephew.
    • This trope is played with in "Deadman's Switch". Aris Boch claims that he's working for Sokar in order to possibly trade a particularly valuable target for the freedom of his family. His target, a Tok'ra operative, reveals that Boch has no family. Then it turns out Boch is a Punch Clock Villain who hates the Goa'uld just as much as our heroes, and Teal'c convinces him to fake his own death to allow SG-1 and the Tok'ra to escape.
  • Even Evil Has Standards:
    • Sokar was deemed as being far worse than his fellow System Lords and was ejected from their ranks.
    • Anubis was banished by the System Lords millennia ago for crimes even they found unspeakable, and they put aside their constant in-fighting to join forces against him after he returned.
  • Everybody Hates Hades: Well, Sokar, who was just a normal god of underworld, but the Goa'uld who adopted the identity actually modelled himself on Satan.
  • Everyone Can See It: By the end of season eight, Carter and O'Neill's attraction has reached a point where multiple characters tell them to stop wasting time and get together already. Vice-President Kinsey explains that it is apparent to anybody who can "read between the lines."
  • Eviler than Thou: The Goa'uld System Lords are all completely evil, but will often fight against each other for territory or other things. Some even manage to outclass the others in pure malevolence:
    • Sokar, who was really into that Satan thing. He beats previous Big Bad Apophis after the latter's failure to conquer Earth, and then captures him to torture him for eternity and eventually dumping him on a hell world, giving Apophis time to plan his revenge.
    • Inverted with Yu, who is a ruthless tyrant like every System Lord, but he still plays things straight when negotiating with the Tau'ri despite their being "inferior" humans. And it was at least implied that he led the call for Anubis's original banishment in part because Anubis was too extreme even by System Lord standards. He was much less megalomaniacal, not desiring galactic conquest and not particularly interested in events outside his area of the galaxy, which included Earth. Yu becomes noticeably more megalomaniacal after his senility set in; the first time he explicitly declared himself a god (despite having, unlike every other known Goa'uld, taken on the persona of a real historical figure instead of a god) was shortly after the viewers were informed that Yu was senile.
    • Anubis was supposedly way too evil even for the Goa'uld. The Goa'uld System Lords enslaved the galaxy and were extreme egomaniacs. Anubis was Dangerously Genre Savvy and his ultimate goal was to erase all life in the entire galaxy (including the total extinction of his own race) and then recreate it according to his own preferences. He was smart enough to trick Oma into letting him ascend, making him an immortal Energy Being far beyond any regular Goa'uld. Furthermore, he made a lot of Goa'uld (including System Lords) work for him, and crushed the rest of them, including most of Yu's fleet.
  • Evil Has a Bad Sense of Humor: Naturally, the Genre Savvy O'Neill does not trust anybody who appears to lack a sense of humor.
  • Evil Is Burning Hot:
    • Sokar's prison moon Netu in "Jolinar's Memories" and "The Devil You Know" was explicitly modeled on Hell, as Sokar impersonates Satan.
    • It is discussed after the introduction of the Ori that fire has historically been associated with demons; Daniel hypothesizes that the Ancients might have deliberately fostered this belief in order to subconsciously prejudice humanity against the fire-themed Ori.
  • Evil Overlord: The Goa'uld are an entire race of this with an accompanying god complex. However, only the highest ranking ones (the so-called 'System Lords') have enough territory and forces to back the claim up, with the rest of the lesser Goa'uld serving one or another of the System Lords and usually plotting their downfall. They collectively control most of the Milky Way Galaxy at the start of the series, but are deeply fractioned and fighting each other more often than outside threats.
  • Evil Redhead: Hathor
  • Evil Sounds Deep:
    • The Goa'uld have deep, reverberating voices that they use to awe their followers. The Tok'ra, being biologically Goa'uld, have voices just as deep, but are among the good guys and use it to denote when they are talking as the Tok'ra entity and not its host. Both can turn it on and off at will.
    • The Kull warrior suits artificially lower the voice of the wearer.
  • Evil Twin: RepliCarter
  • Evil Versus Evil:
    • Anubis vs. System Lords.
    • Replicators vs. System Lords.
    • Ba'al vs. Adria.
  • Evil Versus Oblivion: In season 8, Ba'al, the last of the Goa'uld System Lords, joins forces with the SGC to keep the Replicators from eating the galaxy. Also later helps out against the Ori. The team gets used to him being willing to do this, but never forgets that he is the bad guy (which he does prove now and again. In fact, the end, he becomes the Big Bad of the final SG-1 movie, having outlived Anubis, the Replicators, and the Ori mostly by being Dangerously Genre Savvy.
  • Explosions in Space: Natch.
  • Exposed Extraterrestrials: The Asgard are highly advanced grey space aliens that do not wear clothes. Given that they reproduce via cloning, perhaps they no longer have anything they would consider private parts. Lampshaded in "Ripple Effect"; Col. Mitchell is surprised on first meeting one, and remarks that he was kind of expecting pants.
  • Extra-Strength Masquerade

    F 
  • Facial Markings: The sigil on the foreheads of the Jaffa indicates which Goa'uld they serve or once served in the past. Its composition also indicates their rank: A black tattoo marks the majority of Jaffa, a tattoo filled with silver indicates a Jaffa of high rank in civil administration, and a tattoo filled with gold indicates a First Prime, the ranking military servitor of a Goa'uld.
  • "Facing the Bullets" One-Liner:
    • "The Fourth Horsemen", Part 2:
      Gerak: If I do this, I will die. But, I will die free!
    • "Off the Grid":
      Nerus: But I'm so interesting!
  • Failsafe Failure: Almost called out by name in "Avatar".
  • Fake Memories: "Fire and Water"; "The Fifth Man"; "Beneath the Surface"; "Summit"; "Collateral Damage"; "Dominion"
  • Famed in Story: SG-1 is legendary throughout the galaxy, but Teal'c is particularly famous (or infamous) as "the shol'va" (renegade) who started the Jaffa rebellion and almost personally lead to the downfall of the Goa'uld. Lampshaded in "Beachhead" when Nerus arrives at the SGC and Fanboys out over Teal'c and Dr. Jackson, mentioning what he has heard about their accomplishments. He is then visibly upset at the absence of O'Neill and Carter, saying "This isn't at all the way I imagined it would be."
  • Fan Disservice: The infamous full-frontal scene in "Children of the Gods" is not meant to be sexy.
  • Fanboy: The title character in "Citizen Joe" is a fanboy of SG-1 in every sense of the word. Due to contact with a piece of Ancient Phlebotinum, he's been watching SG-1's heroics in much the same way as the audience has. When he meets SG-1 in person at the end of the episode and starts gushing over them, they're more than a little unnerved. He's essentially an Audience Avatar.
  • Fantastic Aesop: "The Nox". The title species are perfect pacifist space elves who look down on SG-1 for using violence against the Goa'uld, and SG-1 seems to agree with them at the end of the episode. Problem is, the Nox are Sufficiently Advanced Aliens with abilities (invisibility and resurrection) that make pacifism a viable option.
  • Fantastic Drug:
    • The Blood of Sokar is a potent hallucinogen that Apophis uses in conjunction with a memory recall device to interrogate SG-1 and Martouf in "The Devil You Know".
    • The Lucian Alliance's main business is dealing in kassa, an addictive corn-like grain. When not fighting the Ori, the SGC does a lot of kassa interdiction ops. Said operations end up getting SG-1 a serious price on their heads in "Bounty".
  • Fantastic Racism:
    • In abundance, as well as the old-fashioned kind in the episode "The Other Side", wherein the aliens of the week disliked Teal'c not because he is Jaffa, but because he is Black.
    • For the most part the planet Hebridan is a pretty harmonious mixed-race society between the Hebridian humans and the Serrakin who freed them from the Goa'uld. But the antagonist of "Space Race" tried to rig the eponymous race so a pure human would win instead of a Serrakin or mixed-breed. His excuse was that he perceived a pro-Serrakin glass ceiling to his own advancement in the planet's main Mega Corp.. In actual fact, he hadn't been promoted or gotten a raise in so long because he was under investigation for corruption, but they didn't have enough evidence to indict him, until he supplied it by rigging the race... Nice Job Fixing It, Villain.
    • The episode "Allegiance" demonstrates the tension that exists between the Jaffa rebels and the Tok'ra, even though they're nominally allies. The Free Jaffa see the Tok'ra as not so different from the Goa'uld, and certainly don't want to receive orders from them. The Tok'ra, on the other hand, have been chased almost to extinction by the Jaffa soldiers of the Goa'uld. Add in an Ashrak assassin killing them left and right to sow division, and the situation becomes quickly explosive, with the Tau'ri stuck between the two factions.
    • Jack frequently demonstrates this towards the Tok'ra. It's less to do with the fact they have "snakes in their heads", but because the Tok'ra will often treat the host as expendable, but go out of their way to save a symbiote. Add to that, the Tok'ra screwing them over on more than one occasion by seizing technology that SG-1 busted their humps trying to get. Fair to say, Jack's developed some annoyance with their priorities.
  • Fatal Attractor: Daniel Jackson was continuously involved with women who turn evil, have been evil, or become a Goa'uld host. The only person with worse luck in love than Daniel is Carter.
  • Fatal Family Photo: Airman Wells spends the entire first part of "Heroes" showing the ultrasound of his unborn son to the rest of his team, up until he is shot in the back by a Jaffa. He survives.
  • Fate Worse than Death:
    • Becoming a Goa'uld host. Imagine being trapped in your own body, being able to see and hear everything around you, but be powerless to do anything. Now imagine living through this for hundreds or even thousands of years, watching as your Puppeteer Parasite commits atrocity after atrocity. If you're lucky, you'll go insane long before then.
    • The Goa'uld Marduk was so abusive to his subordinates that his own priests rebelled. They locked him in his sarcophagus with a creature that ate him alive at a rate just slow enough for the sarcophagus to heal him before death, forcing him to be eaten alive for eternity. O'Neill terms it the officially worst way to go.
  • Feed the Mole:
    • The Tok'ra allow Tanith to live and believe that he has tricked them in order to feed Apophis false information through him. They decide to stop the subterfuge once they feel that he has outlived his usefulness and the risks of keeping him around outweigh the gains.
    • In "The Other Guys", SG-1 allows themselves to be captured by the Goa'uld Khonsu since they know he is actually a Tok'ra and he has vital information to pass along. However, midway through the episode Her'ak, Khonsu's first prime, reveals that Anubis knew the truth the whole time, and they had simply allowed Khonsu to live until now. Her'ak kills Khonsu and SG-1 is now captive for real.
  • Fictional United Nations: The Alliance of Four Great Races is described as one by Ernest Littlefield in "The Torment of Tantalus," but little is known beyond its membership roster and the fact that the castle on the planet visited in that episode was their equivalent to the UN Building in New York.
  • Fiction as Cover-Up: The SGC allows Wormhole X-Treme! to keep filming in order to serve as a smokescreen for their actual activities.
  • Figure It Out Yourself: The reasoning behind the Ascended Ancients Alien Non-Interference Clause: If a "lower" deserves to ascend then they should be able to figure it out themselves.
  • Five-Man Band: SG-1 finally becomes this in Season 10:
  • Fire-Forged Friends: Pretty much the whole team, but especially O'Neill and Teal'c. Teal'c eventually notes that he considers O'Neill his brother.
  • First Name Basis:
    • Emmett Bregman, shooting a documentary at the SGC, repeatedly tells the colonel he is working with not to call him sir. In their final scene, he finally does call him "Emmett".
    • At the end of "Lost City", when O'Neill is fading away due to the Ancient knowledge downloaded into his mind, Carter pleads for him to stay and calls him "Jack".
    • After Jack has been promoted to General, Hammond insists that he start calling him "George", but Jack says that he tries and it comes out as "General" anyway.
  • Fixed Forward-Facing Weapon: The Ori mother ships have a massive slow firing weapon that frequently decimates any ship it hits. They also carry turrets similar to those on a Ha'tak, but much more powerful (though the main beam still outclasses those by leaps and bounds).
  • Flanderization: In the first season, O'Neill knows what to call the spiralling matter around a black hole (an accretion disk), and along with Teal'c collects data during the black hole observation. Three seasons later, he can't understand or remember what a coronal mass ejection is. However, due to occasional character comments about O'Neill's Obfuscating Stupidity, it's debatable whether he's truly confused about a particular bit of technobabble, or just annoyed by the frequency and duration of it. In fact, it's repeatedly mentioned that O'Neill is much smarter than he lets on, just not in the technical way of Carter or the bookish way of Daniel.

    He does showcase that despite the Obfuscating Stupidity, he does have moments of sheer brilliance. In the Pilot, he tells the SGC to hold off on the million dollar MALP probe to Abydos, and instead throws a box of tissues and a marker pen through the gate. Only afterwards does he simply explain, "Jackson has allergies. He'll know it was from me, instead of someone like you." It works.

    Also, O'Neill is clearly more intelligent than he lets on. Why else do the Asgard hold him in such regard, stop anyone messing with his DNA, and name a new class of ship after him? He was the first human to survive the Ancient knowledge download into his brain and manage to figure a way to seek help before it killed him. When Rodney McKay was similarly advanced by an Ancient device in Atlantis, McKay knew what he was doing when he got smarter. O'Neill doesn't, but he does it all anyway sheerly by acting instinctively.
  • Flashback with the Other Darrin:
    • The "Previously on..." opening to "The Sentinel" featured footage from "Shades of Grey" in order to re-introduce the rogue NID operation that would be important in the episode, but the two NID characters who "returned" did not actually appear in "Shades of Grey." They were edited into the older scenes in order to give the impression that they had been there all along.
    • When Lieutenant Colonel Cameron Mitchell was introduced in season nine, several scenes were filmed that took place during the time frame of season seven's "Lost City" in order to give the impression that he had been part of the team that helped protect SG-1 during the climactic battle.
    • In "200", when discussing possible endings to the Wormhole X-Treme! movie, "fishing" is mentioned, complete with clips from the season eight episode "Moebius" where the season did end with the team going fishing. There is, however, an added clip that includes Mitchell and Vala, who had not yet joined the cast, and O'Neill testily responds that they were not there.
  • Flashed Badge Hijack: Mitchell takes a man's motorcycle when he needs to pursue the people who have kidnapped Vala, and the car he and SG-1 are driving is blocked in its space... by a police car.
  • Flash Step: Objects in hyperspace in the Stargate Verse apparently don't physically travel through the intervening space between point A and point B, meaning they can pass through objects in realspace. This in turn means that a short hyperspace hop can act as this trope, which SG-1 takes advantage of in "Fail Safe" (to jump an asteroid through Earth), in "Redemption, part 2" to dispose of the Beta Stargate that's about to become a gigaton-grade explosion, and "Fallen" (to jump the F-302 through Anubis's shields).
  • Flat Yes: Carter's only response to Major Kawalsky condescendingly asking her if she has ever pulled out of a simulated bombing run in an F-16 at eight-plus Gs is a simple, calm "yes." Kawalsky has to pause and glance around the table before he says anything else.
    Kawalsky: Well... it's way worse than that.
  • Fling a Light into the Future: In "There But for the Grace of God", an unknown race that was about to be wiped out by the Goa'uld in an Alternate Universe broadcast a message containing the attack's staging point's gate address. That universe's SGC (the SGA) picked it up but couldn't understand it because they never learned Goa'uld on Abydos. Then Daniel turned up in that universe thanks to Applied Phlebotinum. He was able to bring back the message to his own SGC and it enabled them to stop the Goa'uld from invading Earth.
  • Flip Personality: The Tok'ra symbiotes and their hosts. The symbiote taking control is revealed by an altered voice and temporarily glowing eyes.
  • Floating Continent: The Nox and their floating city.
  • Flynning: When Mitchell sees two siblings play-fighting with wooden swords, he criticizes them for "moving around like Ed Grimley" and demonstrates a more effective technique in order to gain their favor. When they ask where he learned to fight, he explains that his knowledge comes from broomstick battles with his brother and the Sodan ritual of kel-shek-lo. Oddly, his prior mention of studying fencing in college was not brought up. (He did say that he failed fencing...)
  • Forensic Accounting: Senator Kinsey was read into the project in "Politics" after, in his capacity as chairman of the Senate Appropriations Committee, he demanded to know what the $7.5 billion item in the Air Force budget labeled "Area 52" was.
  • Forgotten Phlebotinum: Since a major part of SG-1's mission statement is to find useful technology this is averted a lot, with some technology appearing frequently over the years after its introduction, but a lot of other technology is forgotten once its episode is over.
  • For the Evulz: In "In the Line of Duty", Teal'c explains that he has seen the Goa'uld exterminate entire species for no purpose other than that it gave them pleasure.
  • Four-Temperament Ensemble: Within the original SG-1. It is not exact, but it works:
    • Sanguine — Carter
    • Choleric — O'Neill
    • Melancholic — Daniel. Poor, poor Daniel.
    • Phlegmatic — Teal'c. Indeed.
  • "Freaky Friday" Flip: The premise of "Holiday", when some phlebotinum built by an aged anti-Goa'uld guerrilla named Machello causes first him and Daniel, then Teal'c and Jack, to swap bodies.
  • Freeze-Frame Bonus:
    • In "The Fifth Race", just after he comes back from the planet and is in the briefing room, O'Neill is sketching absent-mindedly the plans for a makeshift ZPM.
    • The Ascended Times, the newspaper in the Astral Diner in "Threads". The prop guys went the extra mile to write full news stories for it, including that Anubis thinks "O'Neill is a pain in the —"
    • Another article in The Ascended Times reads "Wraith on the way to Atlantis". In the Stargate Atlantis episode "The Brotherhood" which aired two weeks before "Threads", three Wraith Hive Ships were detected heading towards the city, leading into the first season finale "The Siege".
    • During the puppet sequence in 200, there's a close-up shot on a computer keyboard when Dr. Jackson asks to see the symbols on the Stargate in detail. The keys... don't quite follow the QWERTY format and say something rather offensive. Check it out.
    • One of the bonus features on the season 4 DVDs pulls the same trick.
  • Friendly Enemy: The Goa'uld Nerus, who has contacted the SGC in the hopes of working together against the Ori, is almost giddy with anticipation over meeting SG-1, fawning over Teal'c and Daniel Jackson. When he realizes that Colonel Mitchell and Vala are not O'Neill or Carter he becomes despondent, even asking if they might be arriving later.
  • Frontline General: Both Hammond and Jack mostly stayed in the boardroom but neither was above going into the field on occasion. In "Into the Fire" Hammond flew second seat behind Teal'c in a Goa'uld needle-threader, manning the guns during a Gunship Rescue. In "It's Good to Be King", General Jack O'Neill took the helm of a puddle jumper and used it to blow up a Ha'tak.
  • Full-Name Basis: Teal'c uses this for anyone who does not have a military rank.
    Daniel: Can you keep an eye on this for me, Teal'c?
    Teal'c: I will keep both eyes on it, Daniel Jackson.
  • Funny Background Event: In "Menace", when SG-1 and Hammond are talking about the android Reese, Jack starts making faces into a magnifying glass, coincidentally just as Daniel is mentioning how the android has the mind of a child.
