History Characters / StargateSG1SG1

* GenreSavvy: All of them, which is what gives them an edge over the rest of the galaxy more often than not.

* DeadpanSnarker: Jack and Daniel are the biggest culprits, but they all have their moments. Even [[TheStoic Teal'c]]; once he gets the hang of Earth humor, his deadpan is like no other.

* TheAllegedBoss: He admits as much, pointing out that since Carter is the same rank as him, Daniel is a civilian and Teal'c is an alien it's a little tricky getting them to follow orders they don't want to, especially since he's the new guy and they all have years of field experience. Eventually settles into a Type 4 as he gains the respect of his team.

* BadassNormal: He doesn't have the Ancient Gene, he's not an alien {{Badass}}, he's just a normal earthling. He still kicks plenty of ass.

* BrainsAndBrawn: ''Very'' roughly speaking, Carter and Daniel provide the brains while O'Neill and Teal'c provide the brawn. The reality is more complicated, as both O'Neill and Teal'c are much more intelligent that one might first suspect, while Carter and Daniel are definitely capable of kicking ass should the need arise.

* MyGodWhatHaveIDone: [=Replicator!Carter=] seeks Carter's help to prevent a replicator army from invading Earth's galaxy, which has become immune to the Ancient disruptor. Carter trusts her because she believes no-one with her personality could ever work with Fifth. It's the only thing she's right about. [=Replicator!Carter's=] plan is to gain immunity to the disruptor, [[TheStarscream destroy Fifth]], distribute her immunity to the replicator army she's now take control of and establish a foothold in Earth's galaxy. Carter's shocked reaction is 'What have I done?'.

* ScrewTheRulesImDoingWhatsRight: After a year as an ascended being, he gets fed up with AlienNonInterferenceClause and breaks the rules in order to help his friends. It doesn't end well.

%%* MacGyvering

--> '''Teal'c''': While in the service of Apophis I did many things. For these deeds my victims deserve retribution.
--> '''O'Neill''': Can we focus on this one case only for now, please?
--> '''Teal'c''': This case represents the many.
--> '''O'Neill''': Well it shouldn't!
--> (later)
--> '''Teal'c''': Hanno's father was not the first or the last of those whose lives I have taken. And I have done far worse, O'Neill. I can not give all of their loved ones retribution, but I can at least give it to this one.

* KlingonsLoveShakespeare: He's quite a movie buff, as he's [[SawStarWarsTwentySevenTimes seen Star Wars 9 times]], and is familiar enough with DieHard to catch reference to the main character.
* LoopholeAbuse: Like Daniel, Teal'c has avoided punishment for ignoring orders since he's not technically part of the military. Amusingly played with in "Upgrades", when Jack notes that Teal'c can't be punished for this reason, which Hammond acknowledges and points out that not only that, he actually ''did'' follow orders by not embarking on the unauthorised mission with the rest of [=SG-1=], only following them because Hammond ordered him to retrieve them.

%%* UnresolvedSexualTension: Samantha Carter.

%%* UnresolvedSexualTension: Jack O'Neill.

%%* NerdsAreSexy

%%* ThroughTheEyesOfMadness

* FamilyOfChoice: His attitude towards SG-1 once [[spoiler: Sha're is gone]]. As an orphan who was laughed out of his chose field and ridiculed by his contemporaries, he latches on to Sam, Jack, and Teal'c very quickly, obviously viewing them as de-facto siblings.

* AcePilot: O'Neill, Carter, Mitchell, Teal'c and Vala all easily qualify.

* RebelLeader: Tries this on in the season 3 premier. [[spoiler: It doesn't work]].

* UnresolvedSexualTension: By the bucketful with Samantha Carter.

* LikeAnOldMarriedCouple: Practically most of his interaction with Vala.

* UnresolvedSexualTension: By the bucketful with Jack O'Neill.

* BelligerentSexualTension: Pretty much sums up all of her interaction with Daniel.

* {{Greed}}: Her FatalFlaw.
* GroinAttack: One of her specialties.

* LikeAnOldMarriedCouple: Most of her interaction with Daniel.

* TheSmurfettePrinciple: Played straight for the first nine seasons when Sam was the only female member of the team, then subverted in the tenth and final season with the addition of Vala.

* TurnInYourBadge: Subverted. [[spoiler: It was a ReverseMole role he played as part of a sting operation against a rogue element that had infiltrated the SGC.]]

* BadassesWearBandanas: He sometimes wears a bandana in the field instead of the infantry caps worn by Jack and Sam, though it's technically a subversion of the trope until he [[TookALevelInBadass takes a level in badass]].

* BoyishShortHair: Due to Air Force regulations, her hair was initially never allowed to touch her shoulders, though the actual length varied from season to season and several alternate Carters who never joined the military have long hair. Eventually subverted in the series proper, as she grows her hair out and keeps it tied back during the two follow-up movies and her tenure on ''[[Series/StargateAtlantis Atlantis]]''.

* NumberTwo: To O'Neill as the team's military second-in-command, and indeed the ''only'' other military member of the team. Subverted with Mitchell in the later seasons, as they're the same rank and seem to share command more often than not, though he is nominally the leader.

* TheSmurfettePrinciple: Played straight for the first nine seasons, but eventually subverted when Vala joins the team.

* YouAreInCommandNow: She's given command of the team in season eight after O'Neill's promotion, and temporarily takes up the reigns on a number of instances before then whenever he's out of commission. Subverted in the last two seasons, when command is given to Mitchell instead.

* YouCantGoHomeAgain: He's initially branded a traitor by his home country of Kelowna after he steals the naquadria, preventing him from ever returning. This is later subverted due to the changing political situation on Langara however, and he eventually returns to become a respected ambassador for the Kelownan government.

* ClassyCatBurglar: Vala is something of a subversion; she certainly plays up to the role when she wants to, but whenever we actually see her try to steal something onscreen it rarely goes the way she'd planned.
%%* ConMan: Well, woman.

* FiveManBand: After Vala officially joins the team:
** TheLeader: Lt. Col. Cameron Mitchell, of the headstrong variety. At least nominally in charge, though his inexperience and recklessness occasionally exasperate the other team members. Responsible for PuttingTheBandBackTogether after the original team briefly disbanded.
** TheLancer: Dr. Daniel Jackson, civilian archaeologist and TheFace of the team. Often acts as a more jaded {{Foil}} to newcomer Mitchell's enthusiasm, and the most likely to clash with him. Sometimes overlaps with TheSmartGuy.
** TheSmartGuy: Lt. Col. Samantha Carter, resident astrophysicist, OmnidisciplinaryScientist and certified genius. Usually responsible for coming up with the solution to whatever the problem of the week is. Sometimes overlaps with TheLancer.
** TheBigGuy: Teal'c, token ProudWarriorRaceGuy and the most combat-proficient member of the team, as well as being physically the biggest. Mostly a Class 2 with occasional Class 1 leanings.
** TheChick: Vala Mal Doran, the newest addition to the team. More overtly feminine than Carter and neither a soldier nor a scientist by trade, though she's both highly intelligent and more than capable of holding her own in a fight.
* FourPhilosophyEnsemble: Of the original team:
** The Cynic -- O'Neill. Logical, pragmatic, occasionally hostile, has a somewhat shady past.
** The Optimist -- Daniel. Idealistic, self-sacrificing, stubborn, occasionally reckless.
** The Realist -- Carter. Usually the most objective of the team, tends to mediate between the others.
** The Apathetic -- Teal'c. Enigmatic, from a different background to the other characters, sometimes has different priorities.
* FourTemperamentEnsemble: Again, the original team:
** Choleric -- O'Neill. Goal-oriented and a strong leader, but can be harsh and prone to rebelling against authority.
** Sanguine -- Carter. Charming, compassionate, probably the friendliest member of the team but sometimes cares too much what others think.
** Melancholic -- Daniel. Introspective and sensitive but obsessive and prone to mood swings.
** Phlegmatic -- Teal'c. Quiet and dependable but can sometimes appear indifferent.

* WrittenInInfirmity: Michael Shanks came down with appendicitis during the filming of "Nemesis", forcing what the scriptwriter called "the fastest rewrite in history". They chose to give Daniel appendicitis, and had him still recovering from surgery in "Small Victories" (averting HollywoodHealing in the process).

* WrittenInInfirmity: Vala's pregnancy with Adria was due to Claudia Black's own.

[[folder:Colonel Dr. Samantha Carter]]

The token female of the team. Like Daniel Jackson, served as the voice of reason, as opposed to O'Neill's gung-ho approach to problems. As a scientist, was the source of much {{Technobabble}} and AppliedPhlebotinum, usually [[MacGyvering jury-rigged]] to solve this week's problem. Throughout the seasons, she went from "reasonably brilliant" to "genius who would be bathing in Nobel Prizes if not for the secrecy of the Stargate Program". Later promoted to full-bird Colonel and [[{{Transplant}} joined]] the [[Series/StargateAtlantis Atlantis Expedition]] after ''SG-1'' was cancelled. As of ''Series/StargateUniverse'', she has been given command of the ''Daedalus''-class battlecruiser ''George Hammond''. Appeared in more ''[[Franchise/StargateVerse Stargate]]'' episodes than any other character.

* [[MrFixit Ms. Fixit]]: She's usually the person the other characters turn to whenever the Stargate or any of the other AppliedPhlebotinum on the show breaks down.

** The Lancer: Dr. Daniel Jackson, civilian archaeologist and TheFace of the team. Often acts as a more jaded {{Foil}} to newcomer Mitchell's enthusiasm, and the most likely to clash with him. Sometimes overlaps with TheSmartGuy.

* RagtagBunchOfMisfits: The original team comprises a bona fide MilitaryMaverick, a discredited archaeologist and an alien defector; Carter is more normal than the others, but she's still an obsessive {{Woraholic}} with a pathological need to prove herself. Later additions include a convicted traitor who played an indirect role in the death of his predecessor, a former SpacePirate, and the new "commander" who has little if any authority over his team, and knows it. They're still widely considered to be the best at what they do, and have achieved near legend-status by the end of the series.

* FatalAttractor: It seems to be an unspoken rule that any woman Daniel gets involved with will inevitably try to kill him. Both of his major love interests (Sha're and Vala) became Goa'uld hosts at some point, as did his ex-girlfriend Sarah Gardner, who didn't even have anything to do with the Stargate program. He was raped by the Goa'uld queen Hathor, had a brief fling with a genocidal maniac called the [[NamesToRunAwayFromReallyFast "Destroyer of Worlds"]], and that's not even touching on the various one-shot female villains who attempt to hit on him.

* SugarAndIcePersonality: He can empathize with almost anybody and he usually comes across as quite affable and charming, but he's not afraid to let somebody know if he finds them irritating and he's capable of being condescending, snide and passive-aggressive, not to mention grouchy and sarcastic. The "Ice" aspect of his personality is more prevalent in later seasons and usually triggered by either Vala or Mitchell, for [[TheAllegedBoss different]] [[BelligerentSexualTension reasons]].

* TouchedByVorlons: Due to ascended, and the again later on when he briefly becomes a Prior.

* [[MrFixit MsFixit]]: She's usually the person the other characters turn to whenever the Stargate or any of the other AppliedPhlebotinum on the show breaks down.

* InternalReformist: Flashbacks in "Threshold" show that [[mentorArchetype Bra'tac]] instructed him to be this when he was made First Prime, telling him that he may occasionally be able to sway Apophis's decisions and blunt his worst actions.

* MrFanservice: The guy is ''ripped'' and he accordingly gets the most ShirtlessScenes among the male cast, especially after season six when he loses the symbiote and the unsightly pouch disappears.

* BigEater: The first few episodes he appeared in after joining the team showed him almost constantly eating, enthusing about his love for "traditional American cuisine". Then Sam points out that Americans ''also'' have the tradition of [[AWeightAesop hardened arteries]], and this aspect of his character is unceremoniously dropped.

%%* PuttingTheBandBackTogether: Invoked.

%%* TheGadfly

%%* StepfordSmiler: Type A

[[folder:Lieutenant General Jack O'Neill]]
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/Neill_5986.JPG]]
->'''Played By''': Richard Dean Anderson

The leader of the original SG-1 team. Gradually went from the tough, no-nonsense portrayal pioneered by Creator/KurtRussell in the movie to a more light-hearted and [[DeadpanSnarker sarcastic]] character that RDA was more accustomed to playing. Had zero tolerance for {{Technobabble}}. As of ''Series/StargateUniverse'', he is a three-star general.

%%* BunnyEarsLawyer

* TheCombatPragmatist: Though O'Neill shows plenty of restraint, he doesn't play around when he needs to start killing. In the first season, for example, he has no compunctions with sneak-attacking a Jaffa soldier, throwing him to the ground, and cutting his throat.

%%* GoingNative: "A Hundred Days."

* BadassBookworm: Well, as close to {{Badass}} as he could possibly get being a squishy civilian scientist. He has undoubtedly become one at about season seven.

%%* CunningLinguist

* ScienceHero: Well, Archaeologist/Linguist/Egyptologist hero, really, but science is close enough. He's usually the guy who's most likely to understand Carter's TechnoBabble.

%%* NumberTwo

%%* ParentalSubstitute: To Cassandra Fraiser.

%%* TheSquadette

%%* BluntMetaphorsTrauma
%%* BrutalHonesty

%%* TheSpock: Originally.

%%* WarriorPoet

%%* InstantExpert: See PhotographicMemory below.
