History StargateSG1 / AToF

* ColonelBadass: 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 [[TheMole mole]], [[ColonelMakepeace named a trope]].

** Lampshaded in one instance 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.

** Lampshaded by Thor himself in one episode, enlisting SG-1's help for exactly this reason.

* DanceBattler: Any practitioner of the Jaffa martial art Mastaba (seen most prominently in "The Warrior"). In RealLife, 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.

* DepletedPhlebotinumShells: Besides naquadah-enhanced nukes (see the main StargateVerse 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.

* BeethovenWasAnAlienSpy: Literal example. [[http://en.wikipedia.org/wiki/Yu_the_Great Yu the Great]], one of China's earliest emperors, was one of the Goa'uld System Lords. Merlin and Morgan la Fey were ascended Ancients.

** Every team member died at least once and got better, but it happened to Daniel Jackson so many times -- between 6 and [[BeyondTheImpossible 22 times]] over the course of the show, depending on whether you count [[LeftForDead presumed deaths]], [[AlternateReality alternate realities/timelines]], AllJustADream episodes, [[BigFinish expanded universe audio dramas]], etc. -- that it became one of the series' {{Running Gag}}s. Consider this scene where two {{Mauve Shirt}}s are exploring an archeological site on another planet:

* ElaborateUndergroundBase: The SGC, hidden beneath NORAD in the Cheyenne Mountain Air Force Station.

* ElaborateUndergroundBase: The SGC.

* TheAlliance: Oh, geez.
** The Tau'ri, Tok'ra, and Free Jaffa ally against the Goa'uld about halfway through ''SG-1's'' run. Then in season 8 the alliance teams up with the Goa'uld and Asgard to fight the Replicators.
** In the backstory, the Alliance of Four Great Races, composed of the Asgard, Ancients, Nox, and Furlings. At present it is broken: the Ancients ascended, the Nox are PerfectPacifistPeople with their entire race (apparently) confined to one planet, and the Furlings are a NoodleIncident nonentity. The only member with any remaining military presence is the Asgard.
** During the Ori arc, the Tau'ri, Asgard, and Jaffa ally against the Ori.
** The Lucian Alliance is a malevolent version of the trope, a cartel of drug runners that formed in the power vacuum left by the Goa'uld Empire's downfall.

* FacialMarkings: Jaffa are effectively ColorCodedForYourConvenience, as the sigil on their forehead indicates which Goa'uld they serve. Or served, in the case of free Jaffa.

* FantasticDrug: 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, [[CallARabbitASmeerp an addictive corn-like grain]]. When not fighting the Ori, the SGC does a lot of kassa interdiction ops, because, [[DrugsAreBad you know]]... Said operations end up getting SG-1 a serious price on their heads in "Bounty".

* FacialMarkings: Jaffa

** Particularly the US Air Force. Multiple real-life Air Force Chiefs of Staff have appeared on the show, playing themselves.

** The Navy loaned them a submarine for "Small Victories".

** Specifically the US Air Force. Multiple real-life Air Force Chiefs of Staff have appeared on the show, playing themselves.

* DidISayThatOutLoud

* ArmorIsUseless

%% Please do not add a note to this section explaining that SG-1 switched to the P90 for its better armor penetration, this was never mentioned in the show. Jack requested that the entire team carry P90's when they were chasing an Unas, and later mentioned to a Russian colonel that it was his personal preference for a weapon, but armor penetration was never discussed.

** [[StargateSG1/SToZ Tropes S to Z]]

* ActingForTwo:
** Amanda Tapping played multiple Carters in several different episodes. "Point Of View" had '''''Dr.''''' Samantha Carter, "Gemini" featured extended interactions between Carter and ''Repli''Carter, and "Ripple Effect" featured over a dozen Carters in a single scene.
** "Tin Man", where the alien Harlan created robotic duplicates of SG-1. They reappear in "Double Jeopardy," where the two O'Neill's get into a fistfight.

* ActorAllusion:
** The show was fond of making ''MacGyver'' references -- which of course, leads to CelebrityParadox. Lampshaded by Amanda Tapping in a blooper shown in the 200th episode special "Inside the 200th Episode" ([[http://www.youtube.com/watch?v=7PdY3L-JYzk Watch it here]]):
** John Billinsley guest-starred in the season six episode "The Other Guys" as Dr. Coombs, who was a profound {{Trekkie}}. John Billinsley was at the same time starring as Dr. Phlox on ''StarTrekEnterprise''.

** When Vala is pitching story ideas to Martin Lloyd in "200," he immediately recognizes her pitches as retreads of classic stories, including ''Film/TheWizardOfOz'' and ''GilligansIsland''. He recommends that, if she is going to rip off something, make sure it is something nobody has ever heard of. Her next suggestion is ''{{Series/Farscape}}'', the series she (Claudia Black) and Mitchell (Ben Browder) had previously starred in before joining SG-1, with Claudia reprising her role as Aeryn Sun (Browder did not appear as John Crichton, but instead as Stark, while Michael Shanks was Crichton; in a meta-reference to the resemblance between the two actors). [[SelfDeprecation Martin admits that he had never heard of that one.]]

* AffectionatePickpocket: Vala in season 9 episode 3, asking for a parting hug from Daniel -- to steal again the valuable artifact he'd just parted her with.

** The [[http://gateworld.net/wiki/Goa%27uld_hand_device Goa'uld Hand Device]] (also called a "Ribbon device") 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 [[http://gateworld.net/wiki/Pain_stick a cattle-prod 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 [[ThroatLight 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.
* AlienNonInterferenceClause:
** 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.

* AllJustADream:

** [[spoiler: "Absolute Power"]], where Daniel learned the consequences of [[WithGreatPowerComesGreatInsanity gaining access to the Goa'uld genetic memory]].

* AllYourBaseAreBelongToUs: In an alternate reality Daniel found in Season 1 Alternate!Teal'c leads an attack on Stargate Command through the front door. [[spoiler: He kills everyone except Daniel on his way to the Star gate.]]
* AlmostOutOfOxygen: 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, [[ShownTheirWork but rather from high levels of CO2 after they run out of power and the life support systems can no longer recycle the air]].

* AlwaysOnDuty: 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".

* ANaziByAnyOtherName: In "The Other Side", the Eurondans are [[spoiler:white supremacist eugenicists who have gone so far as to poison the entire surface of their planet in attempted ethnic cleansing. SG-1 royally throws a wrench into the works.]]

* AndThenWhat: Seasons eight, nine and ten 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 [[spoiler: 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.
* AnnoyingArrows: Averted

** In "It's Good To Be King," a villager kills a Jaffa ([[ArmorIsUseless through his chainmail armor]]) with a crossbow.

* {{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.

** Standard kevlar body armor worn by USAF personnel have absolutely no affect on either staff weapons or zats (See also the entry on BulletproofVest below).

* AscendedMeme: 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.

* AsskickingEqualsAuthority:

* {{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, ''Series/StargateAtlantis'', followed the expedition that located and explored the city itself.

* BackedByThePentagon:

* BackForTheDead: [[spoiler: 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.]]
* BackFromTheDead:

** Apophis died at the end of "Serpent's Song," but was resurrected by Sokar for further torture and returned in 'The Devil You Know."

* BadFuture: "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 [[SterilityPlague reducing human fertility]] with the plan to conquer the planet once the population has dropped significantly.
* BaldOfAwesome:

* BattleInTheRain: 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.
* BeardOfEvil:

** [[LampshadeHanging Lampshaded]] by Colonel Mitchell in "Ripple Effect:"

-->'''O'Neill''': I always have a reason that I'm not required to explain. It's a military thing.

* BeneficialDisease:

** In one episode, the characters receive armbands that bestow superpowers on the wearers. They work by infecting the wearer with a virus 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 virus.

* BigEater:

* TheBigRace: Season seven episode called, appropriately, "Space Race."
* BilingualBackfire: In "The Scourge," Daniel Jackson and Shen Xiaoyi briefly converse in Mandarin, during which [[BilingualBonus they briefly insult Mitchell]], only for Mitchell to respond (In Mandarin) "Screw you!"
* BilingualBonus:

** In "The Scourge," Daniel Jackson and Shen Xiaoyi briefly converse in Mandarin after being introduced.

'''Shen:''' It shows. (about Mitchell) You're bringing him along?\\

'''Mitchell:''' (in English) Yeah, that's very funny. [[BilingualBackfire (in Mandarin) Screw you!]]

* BluffTheImpostor: 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, [[SomethingOnlyTheyWouldSay and that if he did he would not let Jack near her]], convinces him.
* BluntMetaphorsTrauma: Teal'c, Vala, Bra'tac and Thor... basically, every friendly ProudWarriorRaceGuy and every SufficientlyAdvancedAlien who has not already [[AscendToAHigherPlaneOfExistence ascended to a higher plane of existence]].
** Teal'c eventually got enough exposure to Earth culture to avert this trope in later seasons

* BogglesTheMind: One episode had 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 [[BunnyEarsLawyer filled in 'celestial body' as 'Uma Therman']].
* BoldlyComing: In the first episode to feature the trope in its purest form, [[{{Deconstruction}} 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.

* BottleEpisode: 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.
* BountyHunter:

** 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.

* BugWar: Season nine's "The Scourge," at the end of which the team decides to watch ''Film/StarshipTroopers'' for movie night.
* BulletproofVest:
** [[RealityEnsues A realistic depiction]]. When O'Neill is shot [[InTheBack 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 penetrated, and the impact from the bullet that ''was'' stopped still broke a rib and knocked him unconscious.
** In "Heroes," Dr. Bill Lee explains why standard bulletproof vests do not work against staff weapon blasts, and in some cases actually ''amplify'' the affects of the blast 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. [[spoiler:The inserts end up saving Jack O'Neill's life.]]

* BusmansHoliday: 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.
* ButtMonkey:

** Lieutenant Grogan appeared in two episodes and O'Neill, despite admitting that he was a fine officer, [[LampshadeHanging pointed out that was 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.
* ButYouWereThereAndYouAndYou:
** "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 and Jonas is "Probie" ('[[NewMeat Probationary firefighter]]'). Daniel Jackson appears as a psychiatrist, but there are hints (And it is all but confirmed in the following season) that he is the ''real'' Daniel.
*** Never mind the following season; the real Daniel appears to the real Teal'c at the end of the episode and essentially confirms it.
** In "200," Vala pitched to Martin Lloyd a thinly-disguised [[OffToSeeTheWIzard retelling of]] ''Film/TheWizardOfOz'', 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) and Mitchell, Daniel and Teal'c are the Scarecrow, Cowardly Lion and Tin Man, respectively.

** 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.

* CanonDiscontinuity: 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.
* CantGetAwayWithNuthin: In "Endgame," it is when Walter is taking a break for a cup of coffee, the ''only'' break Walter takes in the ''entire series'', that the stargate is stolen. When Daniel discovers this he briefly begins yelling, [[SubvertedTrope but then tells him that the coffee break had nothing to do with the gate being stolen and not to worry]].

* CastFromHitPoints: When [[spoiler: 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.
* CasualDangerDialogue: 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''.

** Jack O'Neill: "Ah, fer cryin' out loud!" -- "Ya think?" -- "{{You have GOT to be kidding me}}!" -- "O'Neill. Two L's." -- "[[ItMakesSenseInContext Magnets]]."
** Cameron Mitchell: "Like my grandma always said, '*insert proverb or adage here'." -- "That's what I'm talking about!"

** Sam Carter: "With all due respect, sir..." and when positing a logical but probably incorrect guess "I don't think so"

** Rebel Jaffa: "''[[IDieFree I die free!]]''"

* CatFight: "Avenger 2.0" closes with Carter in a fight with Dr. Jay Felger's assistant over who gets his affections...[[DaydreamSurprise before Felger snaps out of it]].

* ChekhovsArmoury: Everyone they meet. Everything they find. Everything they bring back. Everything they do to their Stargate [[strike:beyond simple dialing]]. Even the EngagingChevrons[[invoked]] is a plot point in some episodes (''because'' it is so slow).
* ChekhovsGunman:
** 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 [[spoiler: and is revealed to be an agent of the NID.]]

* ChekhovsLecture: In "The Warrior", K'tano attempts to address O'Neill's objections to the way he runs the Jaffa Rebellion by explaining the [[KlingonPromotion rite of]] ''[[KlingonPromotion joma secu]], whereby any Jaffa has the right to challenge K'tano for leadership if he is dissatisfied. [[spoiler:After Lord Yu reveals to Teal'c that K'tano is [[TheMole 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.]]

* TheChosenZero: 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 with, "Let me get this straight, you need someone ''dumber'' than you?"
-->'''[[DeadpanSnarker Jack O'Neill]]:''' I think we can help you with that.

* ClipShow: Done once a season. Except for season eight's "Citizen Joe" each clip show advanced the plot of the series, sometimes [[NothingIsTheSameAnymore 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".
* CloningBlues: 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 averted it as he did not talk at all.
* CloneDegeneration:

* CloseEnoughTimeline: "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. WordOfGod 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.
* ClothingDamage:
** 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 [[DressingAsTheEnemy 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.
* ColdEquation: In "Tangent," Teal'c and O'Neill are AlmostOutOfOxygen 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.
* CollapsibleHelmet:

** 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."

* ConLang: Goa'uld, the language of (obviously) 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.

** 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.

** The episode "Heroes," though not a ClipShow, 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, [[DiscontinuityNod 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 ''StargateAtlantis'', 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 ''Series/StargateAtlantis''.
** 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.
* ConvergingStreamWeapon: The weapon made out of the six Eyes that Anubis uses on Abydos, in "Full Circle".

* CoolStarship:

* CopBoyfriend: For Sam. [[spoiler: It does not last.]]

* CosmopolitanCouncil: The Goa'uld, whose hosts are male, female, Caucasian, Black, Asian and various combinations thereof. Does not make them any less evil though.
* CouldSayItBut:
** 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 [[IronicEcho "I would never say that."]]
* CourtroomEpisode: "Cor-Ai", "Pretense"
* CowboyBebopAtHisComputer
** The episode summaries that come with the box-set DVD releases for the series are often wildly incorrect with regards to basic information about the show. This includes the occasional misnaming of technology and aliens, [[CriticalResearchFailure but also refers to the show as taking place on a ship, with SG-1 as "the crew".]]
** The text on the back of the DVD cover of the Swedish release of "Children of the Gods" (DVD release of the pilot episode) claims that the villains of the movie are Ra, "the brutal Goa'uld", and ''General Hammond''. This is very not correct.
* CrazyEnoughToWork: 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 one instance 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.

-->'''Thor''': It was your stupid idea, Major Carter.

--> If you immediately know the candle is fire, then the meal was cooked a long time ago.
* CrystalSkull: In "[[ExactlyWhatItSaysOnTheTin Crystal Skull]]"
* CultureClash: 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.

* CurbstompBattle: The [[http://stargate.wikia.com/wiki/Battle_of_P3Y-229 Battle of P3Y-229]]

--> '''Garshaw:''' We cure it all the time, it's no problem.
* CurseCutShort: In "Möbius", when SG-1 gets taken out by a Jaffa grenade.

* CycleOfRevenge: 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.

* DareToBeBadass: Ironically given to a (Up to that point) ''villain'', when Mr. Woolsey [[HeelRealization 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."
* DarkAgeEurope: 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.
* DataCrystal: Used by most space faring peoples.
* DaydreamSurprise:

** In the episode "Grace" Carter has repeated hallucinations of her friends and family, several appear (And might be, or might not be) real.
* [[DeadGuyJunior Dead Girl Junior]]: [[spoiler:Janet]] Wells.
* TheDeadHaveNames: 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 [[spoiler:Janet Fraiser]].

* DeathOfAThousandCuts:

* {{Defictionalization}}: There is a door in the real-life Cheyenne Mountain Complex labelled "Stargate Command," which some sources say has six locks and a guard placed next to it. Whether or not the locks and guard are really there, the door itself leads to a broom closet.
* DeliveryGuy: Daniel Jackson in "Brief Candle," where the team stumbles upon a woman giving birth in an empty temple, and again in "Secrets," [[spoiler: when Sha're, Goa'uld-infested and heavily pregnant with Apophis' child, goes into labor]].

* {{Determinator}}:

* DevelopmentGag: 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."

* DidISayThatOutLoud:
** 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?"
* DieHardOnAnX: "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=]," [[PopculturalOsmosisFailure which Daniel does not understand]], so Teal'c explains that he is referring to [[Film/DieHard the movie]].
* DiggingYourselfDeeper: 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, [[LieDetector 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."

* DirtyCoward:
** Colonel Samuels, an NID-affiliated officer, smugly presented his "Goa'uld buster" weapons as the key to defeating Apophis' attack on Earth in "The Serpent's Lair." When the attack failed to have any appreciable affect, and his subsequent suggestion to send a nuclear weapon to Chulak was overruled as being pointless, he requested to evacuate to the Alpha Site. General Hammond seemed to almost take glee in denying his request, explaining that the idea was to send the best and brightest and Samuels did not qualify.

* DiscontinuityNod: See also CanonDiscontinuity
** 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 ShowWithinAShow 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.
* DiscriminateAndSwitch:

** [[InvertedTrope Inverted]] in "The Other Side." The Eurondans are extremely uncomfortable around Teal'c, with the implication that it is [[FantasticRacism because he is a Jaffa]], but it turns out that they are just regular old "hate black people" racists, regardless of their planet of origin.

'''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.\\

* DistractedByTheSexy: 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.

* DoctorDoctorDoctor:

* DocumentaryEpisode: 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, [[ContinuityNod discussions of past events]], and debates on whether or not the program should be kept secret from the public. Scenes from the documentary [[ArtShift are filmed with different lighting and staging]] to reflect the presence of an in-show camera.

* DoingItForTheArt: One of the "flashbacks" from "200" featured an incident where O'Neill was rendered invisible; one of the scenes featured him walking down a hallway and talking with Teal'c, but since he was invisible he could only be located by the coffeee cup that he was carrying at the time. The plan was to have one of Richard Dean Anderson's stand-ins or stunt-doubles actually perform the scene, since it would require wearing a full-body green suit in order to have the body edited out in post production, but RDA insisted on actually performing the scene himself. You still cannot see him, since he is invisible, but hopefully you can just ''tell'' that it is '''really''' O'Neill walking with Teal'c.

* DrivenToSuicide:
** In "The Light," Daniel and the members of SG-5 go through withdrawl after leaving a Goa'uld "opium den" (Note: Not actually about opium), and attempt to kill themselves. The episode opens with Lieutenant Bader running directly into the kawoosh of an opening stargate.

* DroppedABridgeOnHim: [[spoiler: 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.
* DueToTheDead:
** In "Forever in a Day," an Abydonian funeral is witnessed. It draws heavily from [[AncientEgypt Egyptian]] funerary rights, including the preservation of organs in canopic jars and weighing the deceased heart against a feather.

* DullSurprise: 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.
* DyingAsYourself:
** When Klorel is shot in "Within the Serpent's Grasp," Skaara briefly awakens and smiles at O'Neill.

* DynamicEntry: In "Talion," Teal'c kidnaps Ba'kal by walking out of the shadows and knocking him out with a blow to the face.
* EarlyInstallmentWeirdness: The later seasons definitively established that beings with naquadah in their bloodstream, including Jaffa, could "[[ByTheEyesOfTheBlind 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.

* EnemyMine:

** The Tau'ri, Tok'ra and rebel Jaffa cooperate with the Goa'uld against the Replicators, who launched a full-scale invasion of the Milky Way in "Reckoning."

* EpicFail: 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''.

* EvilIsBurningHot:

* EvilSoundsDeep:

* EvilTwin: [[spoiler:[=RepliCarter=]]].

* ExposedExtraterrestrials: 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. {{Lampshade}}d in "Ripple Effect;" Col. Mitchell is surprised on first meeting one, and remarks that he was kind of expecting pants.
* {{Expy}}: The Goa'uld bear many similarities to a creature encountered by the ''Enterprise'' in ''Series/StarTrekTheNextGeneration'' in season one: a worm-like creature that attaches to the spinal cord, cannot be removed, grants superhuman strength and assumes control of the host body.

* FacingTheBulletsOneLiner:
-->'''Gerak:''' If I do this, I will die. But, [[IDieFree I will die free!]] ("The Fourth Horsemen", Part 2)
-->'''Ne'rus:''' But I'm so interesting. ("Off the Grid")

* FakeAmerican: Filmed in Canada, so a large segment of the cast.
* FakeMemories: "Fire and Water", "The Fifth Man", "Beneath the Surface", "Summit", "Collateral Damage", "Dominion".
* FakeNationality: Perhaps most notably, English actors Gary Chalk and Marina Sirtis play Russians.
* FakeRussian: With BilingualBonus and shades of NoFourthWall at times if you can handle the bad grammar.
* FamedInStory: SG-1 is legendary throughout the galaxy, but Teal'c is particularly famous (Or infamous) as 'the shol'va' (traitor) who started the Jaffa rebellion and almost personally lead to the downfall of the Goa'uld.

* FeedTheMole:
** The Tok'ra allow Tanith to live and believe that he has tricked them in order to feed Apophis false information through him. [[spoiler: 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.

* FirstNameBasis:
** Emmett Bregman, shooting a documentary at the SGC, repeatedly tells the colonel he is working with [[DontCallMeSir 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 'General' anyway.
* FlashbackWithTheOtherDarrin:
** 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' [[RememberTheNewGuy 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.

** 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.
* FlashedBadgeHijack: 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''.

* FlingALightIntoTheFuture: In "There But For the Grace of God", an unknown race that was about to be wiped out by the Goa'uld in an AlternateUniverse 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 AppliedPhlebotinum. He was able to bring back the message to his own SGC and it enabled them to stop the Goa'uld from invading Earth.

* FirstContactMath: The Asgard do not reveal their true selves to a people until they have demonstrated that they understand pi (The ratio of a circle's radius to its circumference), indicating that they have developed sufficient science to understand their existence as "aliens" and not "gods."

* ForTheEvulz: 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.

[[Series/{{StargateSG-1}} Back to main.]]

* CycleOfRevenge: 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* DanceBattler: Any practitioner of the Jaffa martial art Mastaba (seen most prominently in "The Warrior"). In RealLife, 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.

* CyanidePill: Carried by all the Russians working with the SGC.

* {{Expy}}: The Goa'uld bear many similarities to a creature encountered by the ''Enterprise'' in ''Star Trek TheNextGeneration'' in season one: a worm-like creature that attaches to the spinal cord, cannot be removed, grants superhuman strength and assumes control of the host body.

* FridgeHorror: It's been demonstration that knowledge of the stargate's abilities is limited to Stargate Command and other SufficientlyAdvancedAlien species while all the other societies have no knowledge that it's dangerous to stand in front of the gate when a wormhole is activated. That means every time Earth dials up a new planet to explore they run the risk of vaporizing uninformed masses of people.

* BoardToDeath: Ba'al to all his clones. [[spoiler:At least most of them.]]

* BossInMookClothing: Anubis's Kull warriors. Their armor is [[MadeOfIron impervious to everything from machine guns to staff weapons to claymores]] and [[BeamSpam equipped with dual wrist-mounted rapid-fire staff weapons]]. Killing them requires a specialized energy weapon that negates the the advanced technology that granted hem life in the first place.

** [[RealityEnsues A realistic depiction]]. When O'Neill is shot [[InTheBack 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 penetrated, and the impact from the bullet that ''was'' stopped still broke a rib and knocked him unconcious.

* CartwrightCurse: [[WordOfGod 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 Shannahan 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.
