[[folder:The Atlantis Expedition - Main characters]]

!!Dr. Elizabeth Weir (Torri Higginson)
[[quoteright:218:http://static.tvtropes.org/pmwiki/pub/images/elizabeth-weir-stargate-atlantis-11801714-1450-967_3545.jpg]]

The original leader of the Atlantis expedition. An experienced diplomat prior to getting involved with extraterrestrial stuff, she prefers negotiation and talks to confrontation. Was left behind on Asuras in Season Four, and was replaced by Colonel Carter.

Associated tropes:
* BewareOfTheNiceOnes: As Kavanaugh discovered.
%%* BrainyBrunette
* IronLady: Governs Atlantis with a poker face and rarely shows weakness to anyone. (With the possible exception of Sheppard).
%%* HeroicSacrifice
* TheKirk: Fulfills this role occasionally, especially when mediating between [[TheSpock McKay]] and [[TheMcCoy Sheppard]].
%%* PutOnABusToHell
* OnlySaneMan: At times. What with having to deal with [[{{MadScientist}} McKay's]] tantrums, [[{{HairTriggerTemper}} Ronon's]] violent tendencies, [[{{ProudWarriorRaceGuy}} Teyla and the Athosians]] tribal customs and [[{{ChronicHeroSyndrome}} Sheppard's]] near-death experiences.
* PluckyGirl: Not much of a fighter, but she's got guts.
* RedOniBlueOni: The Blue to Sheppard's Red. Generally in any situation, Sheppard will blast in, shoot someone and Weir will clear up the mess.
* ShipperOnDeck: Retroactively revealed to be one for Teyla and Kanaan.
* ShipTease: With Sheppard
* StrawCivilian: At first, but she grows out of it. She will usually receive open contempt from the military people she interacts with, until she proves her worth to them.
* SilkHidingSteel: She's faced the Genii, Goa'uld, Asuran's and IOA, with nothing but her wits to prevent certain death.
* [[{{TheSmartGuy}} The Smart Girl]]: Has ''two'' doctorates, though she focuses on humanities (politics and languages) rather than sciences like [=McKay=].
%%* TeamMom
* TouchedByVorlons: [[spoiler:Became part-Replicator.]]
* {{Transplant}}: First appeared in the ''SG-1'' Season 7 two-part finale. It was known at the time that she would be moving to ''Atlantis'', although it was not known that it would be a parallel spin-off instead of a sequel show.
* WhatMeasureIsANonHuman: [[spoiler:''Self''-applied.]]
* TheWomanWearingTheQueenlyMask: Despite being a commander rather than royalty the trope certainly fits, as she deals with the pressure of being leader of Atlantis with incredible control throughout the series. She may ''feel'' terrified but she'll be damned if anyone ''see's'' it.
* UnresolvedSexualTension: With Sheppard: the two share the burden of command, confide worries to each other unbeknownst to the rest of TheTeam and when the other is in trouble their worry is noticably stronger compared to their other friends. The actors also deliberately played the characters from a romantic angle.
* WillTheyOrWontThey: With Sheppard. [[spoiler: They don't, at least, not that anyone knows of.]]

!!John Sheppard (Joe Flanigan)
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/shepperd_229.jpg]]

Originally picked because of his natural skill with Ancient technology. Known for having a bit of a problem with authority, but is a highly capable commander. Became Atlantis' ranking military officer and the leader of their main off-world team. Has a profoundly strong expression of the ATA gene.

Associated tropes:
* AcePilot: If it has wings, rotors, thrusters, anti-grav emitters, or any combination of the above, he can fly it.
* AmicablyDivorced: Sheppard and his ex-wife Nancy divorced due to the high risk of his job, but are on friendly enough terms that she uses her position at Homeland Security to pass along important information to him regarding an investigation of his.
* TheAtoner: Admits he constantly tortures himself for his past mistakes and shows a capacity for near suicidal self sacrifice. For more details see BrokenAce.
* {{Badass}}: Mind-boggling quantities of it. In one (two-part) episode in Season 1, kills about seventy Genii troops on his own (though 55 of those ran into the Atlantis stargate's shield).
-->'''Dr. Beckett''': ''(looking at a life-signs detector)'' These dots don't tell us much about who's who. How do we know which one's the Major?
-->'''Lt. Ford''': He'll be the dot getting rid of the other dots.
* BrokenAce: Attractive, charming, beloved by his team, MENSA accepted and the best Ancient pilot in two galaxies but also self hating, guilt ridden and secretly believes he deserves to be punished for every failure in his life.
* BoldlyComing: He's notorious for hooking up with and getting hit on by alien chicks. [=McKay=] nicknames him "Kirk" becomes of this.
* BunnyEarsLawyer: Sheppard, when given the right motivation, is a very accomplished pilot and soldier. He just prefers to goof off instead.
* BrilliantButLazy: Sheppard is smart enough to join MENSA, but preferred not to join, and admits that he's "naturally lazy". He's also proved on multiple occasions that he does take his rank and position as Atlantis's military leader seriously.
* ChronicHeroSyndrome: Overly eager to put his life on the line, whether its to save the city, his team, Elizabeth or strangers he's just met.
* ColonelBadass: After his promotion at the start of Season Two.
* DangerouslyGenreSavvy: Knows ''exactly'' what sort of genre he's in and what roles everyone plays. Especially pronounced when the genre changes or a new subgenre is added.
* DayInTheLimelight: Despite being the main character, actually has a really awesome one of these, Doppelganger, in which he gets to play an evil energy being that looks exactly like himself (because the entity was first in Sheppard, and so took his appearance).
%%* DeadpanSnarker
%%* TheHero
* HeroicSacrifice: Defied. [[spoiler: Flies a cloaked jumper carrying a Genii nuke into one of the hives besieging Atlantis at the end of Season 1, planning to detonate it with him inside. The Daedalus shows up at that moment and beams Sheppard out before the jumper explodes.]]
* InstantExpert: Has an incredibly good degree of control over Ancient Technology.
* TheKirk: Fulfills this role on his team, with [=McKay=] as the [[TheSpock everlasting Spock]], and [[FieryRedhead Teyla]] and [[BloodKnight Ronon]] as [[TheMcCoy the McCoys]].
* MajorlyAwesome: In the first season.
* MarriedToTheJob: His job was so secretive and he was so devoted to it that it led to his divorce.
* TheMcCoy: Is this in relation to [=McKay=] in many disputes, with [[IronLady Weir]] taking his place as [[TheKirk Kirk]].
* MildlyMilitary: His lax attitude has gotten him nearly court martialled more than once.
%%* MrFanservice
* TheNicknamer: Has given names to no fewer than five Wraith. First there was Steve, on whom they tested the Hoffan drug, and who died as a result.. Then there was Bob, whom Sheppard and crew captured and interrogated prior to the Siege at the end of the first season, and who ended up shot to death by Sheppard when he wouldn't give up any good intel. Then there was Michael, who became the closest the series has to a BigBad. Then there was Todd ("Guy I knew in college. Very pale."), the NobleDemon and LovableTraitor who probably ended up helping the Atlantis expedition more than any other non-Atlantis character, with the possible exception of the Travellers. And finally there was Kenny, Todd's second-in-command.
* NotAfraidToDie: Definately, and even hinted to be a DeathSeeker. He's shown to be haunted by his past mistakes and whenever there's a suicide mission he's the first to volunteer.
* ObfuscatingStupidity: His detractors tend to underestimate his easy-going personality, believing him to be completely undeserving of his rank and position. It usually comes back to bite them in the ass when Sheppard's sharp unconventional thinking give way to show how good he really is.
%%* TeamDad
* RebelPrince: Was groomed to take over his father's business enterprise but chose to join the Air Force instead, passing the buck to his brother.
* RedHerringShirt: Was introduced this way in the ''SG-1'' episode debuting Atlantis.
* ShipTease: With Elizabeth.
* ShellShockedVeteran / SurvivorGuilt: Whilst serving in Afghanistan, he watched best friends Mitch and Dex killed when their helicopter was hit by a RPG. He similarly failed to save downed pilot, Captain Holland, disobeying direct orders not to mount a rescue mission and getting ''himself'' shot down in the process, earning him a permanent black mark on his record.
* WillTheyOrWontThey: With Elizabeth. [[spoiler: They don't, as she gets killed off beforehand.]]
* UnresolvedSexualTension: With Elizabeth or Teyla, depending on the episode. More frequently with Elizabeth later on, as Ronon appeared and Teyla eventually hooked up with someone else. (Although, he did hallucinate having dinner date with Teyla). [[spoiler:Elizabeth was eventually captured,]] leaving Sheppard grief-stricken for the remainder of the show and ironically, the only long running cast member that was single at the end of the series. The semi-canon tie-in novels resolve his UST with Teyla, though whether they qualify as Canon is very dubious.

!!Dr. Meredith Rodney [=McKay=] (David Hewlett)
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/dr_rodney_mckay_2407.jpg]]

Atlantis' lead scientist. A brilliant astrophysicist, but also a JerkWithAHeartOfGold, an InsufferableGenius, and a [[ArsonMurderAndJaywalking Canadian]].

Associated tropes:
* AlwaysSomeoneBetter: A few episode hints he might have a few shades of this towards Colonel Carter. In their first appearance (And most of his appearance on SG-1) she'd end up proving him wrong, and its implied that, along with massive UST for the colonel, Rodney is ''excessively'' aware she's better than him and desperately seeks to prove himself her equal, especially to her.
* BigEater: Justified by his hypoglycemia. [[AlternativeCharacterInterpretation Or is his claim of having hypoglycemia just an excuse to eat more?]]
* BioAugmentation: He went through gene therapy in order to be able to use Ancient technology.
* CharacterDevelopment: Most likely undergoes more of this than any other character in the series. If not the entire franchise.
* ChildHater: He's hilariously uncomfortable around children, so naturally, they tend to adore him.
* ChivalrousPervert: He might be often DistractedByTheSexy and openly joke about his long-standing lust for Carter, but he tends to be very nervous and {{Adorkable}} when actually pursuing women, such as Katie Brown and Jennifer Keller.
* CluelessChickMagnet: Surprisingly often, usually with [=McKay=] being [[ObliviousToLove utterly oblivious]] until it's pointed out.
* CowardlyLion: The guy frets like clockwork about their impending doom when it happens, but somehow frequently ends up coming up with some of his best schemes to extricate everyone from the impending doom while in such a state.
* DidYouJustFlipOffCthulhu: Rodney cannot help but point out BondVillainStupidity wherever he sees it, belittling the various [[BigBad Big Bads]] for their idiotic plans even when being held hostage and threatened with torture or execution.
* EmbarrassingFirstName: Revealed about half way into the series once the team meets his sister. He prefers to go by his middle name, Rodney.
* InsufferableGenius: A very strong trait of his when he's first introduced in SG-1. It becomes much less prominent once he's spent some time in Atlantis and he gets some character development.
* JerkWithAHeartOfGold: While he may be rude and condescending to those around him, the doesn't mean he won't give his life to save them.
* LetsGetDangerous: Rodney is a coward most of the time, but if you corner him, get him sufficiently angry, or especially threaten his friends, watch out.
* NeverLiveItDown: In-universe. He once accidentally destroyed a solar system, and the rest of the team won't let him forget it. Luckily, it was uninhabited.
* PerpetualFrowner: It's because his vast intellect causes Rodney's mind to jump to very worst possibility imaginable. Seeing a Half-Empty Glass on a table will make him wonder just ''when'' it'll roll off the table, shatter, causing a laceration that gets infected, forcing him to amputate his hand with a rusty saw, causing him to die from Tetanis.
* ScienceHero: As far as [[InsufferableGenius he's concerned]], he's ''the'' resident ScienceHero of the Pegasus Galaxy. And he's probably right.
* TheEngineer: Rodney is much more a theoretical physicist than an engineer, but he becomes one when the situation demands it. Engineering was actually his second Doctorate.
* TheSmartGuy: Along with Zelenka, he's the go-to-guy to fix up a tech solution to get the team out of some mess. He's well aware of it, and is [[InsufferableGenius more than willing to boast about it]].
%%* TheSpock: So much of.
* SpottingTheThread: In both "Home" and "Phantoms", [=McKay=] eventually notices that something is wrong with "reality" because both science and the laws of physics simply do not ''work'' that way.
* UndyingLoyalty:
** There is very little that Rodney won't do for the team, if pushed. He once spends the last 25 years of his life (in a deleted timeline) developing a holographic companion for Sheppard when a time travel accident sends Sheppard 100,000 years into the future.
** His alternate universe counterpart "Rod" is no slouch either, volunteering for a dangerous mission into another reality to save his Atlantis from destruction, before returning home via equally dangerous means because he "couldn't abandon his team".
* {{Transplant}}: Appeared on SG-1 well before Atlantis.

!!Teyla Emmagan (Rachel Luttrell)
[[quoteright:200:http://static.tvtropes.org/pmwiki/pub/images/200px-teyla_emmagan_stargate_1079.jpg]]

Leader of the Athosians. Joins Sheppard's team after Athos is destroyed in the pilot.

Associated tropes:
%%* AbsoluteCleavage
%%* ActionGirl: She's later promoted to ActionMom.
* BareYourMidriff: All of her civilian clothes.
* BoobsOfSteel: Her bust size is modestly larger than Weir, Carter, or Keller, and she will kick your ass.
%%* DarkSkinnedRedhead
%%* FieryRedhead
%%* MamaBear
* MsFanservice: In terms of an actual character, Teyla is given very little to do, and scenes of her sparring with either Ronon or Sheppard as a means of opening an episode became suspiciously frequent. She does get ''some'' screen time, but it is usually only to show her fighting. In terms of who she is as a person, we really learn very little.
* TheMcCoy: Always, though sometimes has competition in this regard from the equally emotional Ronon, but she's far more compassionate and much less violent.
* PragmaticHero: Usually, she is the voice of compassion on the team, but she has the potential for extreme ruthlessness, especially when [[MamaBear her child or husband]] are threatened.
* PregnantHostage: Was kidnapped while pregnant.
* [[ProudWarriorRaceGuy Proud Warrior Race Girl]]: Not an extreme example; much closer to Proud Hunter Race Girl.
* RealLifeWritesThePlot: Rachel Luttrell's pregnancy was written into the show.
* ShipperOnDeck: Ships Elizabeth with a one-off character in the third-season episode Sunday, clearly with the goal of getting her to [[YouNeedToGetLaid unwind a little]].
* UnresolvedSexualTension: With Sheppard or Ronon, depending on the episode. She is close to both men; using Sheppard's name as her son's middle name (though, at that point, it's probably more just gratitude and enormous respect), and bonding with Ronon due to their shared history under the Wraith threat and status as the 'outsiders' of Atlantis. However [[spoiler:neither relationship went anywhere]], as she hooked up with [[spoiler:Kanaan and became a mother.]]

!!Lt. Aiden Ford (Rainbow Sun Francks)

A member of Sheppard's team. Didn't get much CharacterDevelopment in Season One; they didn't seem to know what to do with him. At the start of Season Two, became addicted to a Wraith enzyme and went rogue and was replaced by Ronon, a more colorful character with an interesting backstory. Was last seen in the Season Two mid-season two-parter; now everyone on the show talks like it's taken for granted they will never run into him again.

Associated tropes:
* BusCrash: They gave us a ''huge'' hint that he might show up again but he never did.
%%* DemotedToExtra
%%* TheGenericGuy
* NiceGuy: Was always friendly towards others, even people like Rodney.
* PerpetualSmiler: Not too much, but noticeable.
* ReassignedToAntarctica: A literal example in "Home", where this happens to him in the LotusEaterMachine.
%%* WeHardlyKnewYe
* WhatTheHellHero: A non-verbal one in "The Eye", when Beckett's facial expressions makes it look like he doesn't believe Teyla's claim that she didn't kill Tyrus in "Underground", Ford gives him a DeathGlare in response.
* WhatHappenedToTheMouse: His return was left open since the team NeverFoundTheBody. [[spoiler: Unfortunately, he appears to be dead after all]].

!!Dr. Carson Beckett (Paul [=McGillion=])
[[quoteright:199:http://static.tvtropes.org/pmwiki/pub/images/carson-beckett-199x300_2840.jpg]]

Atlantis' senior medical officer. Scottish. Has the ATA gene, but is afraid of using Ancient technology.

Associated tropes:
* BadassNormal: He doesn't fight often, being a doctor. But when he does he fights for keeps.
* BackFromTheDead: [[spoiler:Subverted, sort of, it's [[CloningBlues complicated]].]]
%%* BewareTheNiceOnes
%%* CloningBlues
%%* DroppedABridgeOnHim
* {{Expy}}: Of [[Series/StarTrekTheOriginalSeries Dr. McCoy]]. Even lampshaded in "Poisoning The Well";
--> '''Sheppard''': He's worse than Doctor [=McCoy=].
--> '''Teyla''': Who?
--> '''Sheppard''': The TV character that Doctor Beckett plays in real life.
%%* TheHeart
%%* HospitalHottie
%%* LovableNerd
* TheMcCoy: Oftentimes, and very much in the classical sense. Often tries so hard to help everyone that he has to be reasoned with or even physically restrained to preserve his own safety (very important, considering he's by far the most qualified medical doctor/surgeon in the ''entire galaxy'', for quite a while).
* MeaningfulFuneral: [[spoiler:The first one we actually see on the show, though Dr. Weir does refer to the people who already died on the show.]]
%%* TheMedic
* PatrioticFervor: Wears the Scottish flag as his mission patch, despite Scotland being part of the UK. Noticeable, since English characters, such as Peter Grodin, wear the Union Flag and not the England Flag. This would imply that Beckett ''specifically'' asked for his patch to be this way.
* PromotionToOpeningTitles: Season Two.
* YouLookFamiliar: Previously appeared in SG-1 as the Young Ernest Littlefield in "Torment of Tantalus".

!!Ronon Dex (Jason Momoa)
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/ronon_dex_8616.jpg]]

Satedan warrior. After the fall of his homeworld, the Wraith implanted him with a tracking device and hunted him for sport from planet to planet for years. Replaced Ford and became TheBigGuy.

Associated tropes:
* BackToBackBadasses: Once with Teal'c, and about 40 times with Sheppard and the rest of the team.
%%* {{Badass}}
%%* BadassBeard
* BadassFamily: According to Ronon, his grandfather taught him hand-to-hand combat, in addition to how to use a triple-barreled shotgun when he was just ten years old.
* BadassNormal: Sheppard and [=McKay=] have the ATA gene. Teyla has the ability to sense [[spoiler:and later sightjack]] the Wraith. What does Ronon have? A particle magnum, years of military service, and seven years of surviving Wraith attacks ''by himself.''
* BerserkButton: Go ahead, talk about Sateda, or better yet, insult his honor.
* TheBerserker: Ronon ''loves'' violence, to the point of it inducing the altered state associated with this trope.
%%* TheBigGuy
* CelibateHero: Despite getting a ''[[FemaleGaze lot]]'' of [[EatingTheEyeCandy attention]] from the female base personnel on Atlantis, Ronon has no romantic attachments over the course of the series. The closest he gets is a ShipTease with Keller, but loses the battle [[BettyAndVeronica for her affections]] to [=McKay=]. He does get a MaybeEverAfter with Amelia Banks in the last episode, though.
* CrusadingWidower: Although flashbacks in "Sateda" imply he was in a relationship with Melena, the hospital worker who perished in an explosion during the fall of their homeworld. "Sunday" implies that she was his fiancee, as he tells Sheppard that he wasn't married, but "close enough".
%%* DreadlockWarrior
* EnemyMine:
** Subverted in "Michael". Despite the eponymous character having lost his memories of being a Wraith, believing himself to be a amnesiac soldier, Ronan ''still'' remains completely hostile to Michael throughout the episode and repeatedly looks for even the slightest excuse to try to kill him.
** Played straight in an alternate reality shown in "''The Last Man''", where Ronon and Todd become BackToBackBadasses, teaming up in order to destroy a Wraith hive and sacrificing themselves in the process.
* {{Expy}}: He's a hot-headed version of Teal'c. There are several differences, however. Not only is Ronon's backstory very different, but the Jaffa were also a more conventional army than Ronon's old force is shown as being, and Teal'c was also [[OfficerAndAGentleman more elegant, and disciplined]]. Ronon eats with his hands, and is generally more of a [[TheBerserker berserker]].
* HairTriggerTemper: A very very ''very'' '''VERY''' short temper.
* TheHunterBecomesTheHunted: He hunted his Wraith pursuers just as much as they hunted him.
%%* JerkWithAHeartOfGold
* KnifeNut: Only three things are infinite: The universe, human stupidity, and [[http://www.youtube.com/watch?v=1q0f6qxhOJI Ronon's supply of hidden knives]].
-->'''Lt.Col. Sheppard:''' How many of those do you have?
-->'''Ronon:''' How many do you need?
* MeaningfulName: "Ronon" is pronounced like "ronin"--the term for a masterless, wandering samurai. Given his backstory, his situation when he meets the Atlantis team, and his fondness for blades...
* TheMcCoy: Often, in a very bloody-minded way.
%%* MrFanservice
* MultiRangedMaster: There probably isn't a weapon type in existence, that Ronon can't immediately pick up and use. He is shown as being a very competent wrestler/grappler as well.
* PerpetualFrowner: Rarely smiles, but it's worth it when he does.
%%* ProudWarriorRaceGuy
* ShellShockedVeteran: Due to the fall of Sateda, the annihilation of his race at the hands of the Wraith and witnessing the death of his fiancee right in front of his eyes, before being forced to spend over seven years as a Runner.
* ShipperOnDeck: He ships Sheppard/Teyla.
* ShutUpHannibal: Talking too much, for villains, tends to end with a mouthful of gun.
* StunGun: His pistol does have a stun setting, though he often needs to be reminded to use it. Ronon prefers to keep it set at the [[TheresNoKillLikeOverkill highest kill setting possible]], particularly when dealing with Wraith.
* TheDeterminator: He seems intent to depopulate the Wraith species on his own.
* TraumaCongaLine: Seriously, could they have screwed this guy worse?

!!Dr. Jennifer Keller ({{Jewel Staite}})

Replaced Beckett as chief medical officer for the last two seasons.

Associated tropes:
%%* HiddenDepths
%%* HospitalHottie
* ImprobableAge: She's named the head of the expedition's medical team at the ripe old age of ''twenty-six.''
* TheLoad: Freely acknowledges being this in "Missing", although by the end of the episode she manages to take a few [[TookALevelInBadass levels in badass]] at least.
* LoveTriangle: Between Rodney and Ronon. [[spoiler:She chose Rodney]].
%%* TheMedic
* PromotionToOpeningTitles: Season Five.
* TeenGenius: Supposedly how she got the head doctor's job so young.

!!Colonel Samantha Carter (Creator/AmandaTapping)

{{Transplant}} from ''Series/StargateSG1''. Replaced Weir as head of the Atlantis Expedition for Season Four.

Associated tropes:
* ActionGirl: Though she doesn't get to show off her combat talents much anymore.
%%* BadassBookworm
%%* HotScientist
* TheKirk: Pulls this off sometimes, despite having an extremely hard science background like [=McKay=]
%%* MacGyvering
* SeenItAll: Often lampshaded.
* [[TheSmartGuy The Smart Girl]]: Overlapping with TheLancer.
%%* TheSquadette
%%* OmnidisciplinaryScientist
* {{Transplant}}: From ''SG-1''.

!!Richard Woolsey (Robert Picardo)

A high-ranking IOA operative, who primarily performed reviews of both Stargate Command and Atlantis and made reports back to the IOA committee. Due to his being a bureaucrat and his job necessitating judging the actions of the main characters, he is not the most popular person in the Stargate program. Despite this, he is known as a fairly reasonable bureaucrat, and is willing to forgive some rule-bending if the results are satisfactory. Succeeds Carter as leader of the Altantis Expedition in Season Five.

Associated tropes:
* BadassBoast
--> "I was Harvard Law Review. I was chief counsel of the US Army Corps of Engineers. Prior to that, I was an appellate advocate for Hartshorne & Slaughter, one of the most prestigious litigation boutiques in all New York City. Believe me, I can handle three tribal leaders with a stack of papyrus."
* BadassBureaucrat: Once he undergoes some loosening up, he uses his eminent skill in navigating bureaucracies for the betterment of the Atlantis expedition.
* BreakTheHaughty: Continuing his arc from SG-1, as he learns to take himself less seriously and know when to bend the rules.
* ButtMonkey: Nobody liked the fact that he replaced Carter, especially [[BadFuture Sheppard]]. None of them made any effort to hide this from him either. For a while he was bordering on being TheWoobie. Even Atlantis ''itself'' won't give the guy a break sometimes. There was a time the motion-sensing door of a conference room closed and decided to ignore his efforts to reopen it.
* CharacterDevelopment: Learns to bend the rules and become less of an ObstructiveBureaucrat during his time in command, continuing this character arc from [=SG1=]. The writers and producers referred to his arc as being one of redemption.
* CowardlyLion: When he was first introduced. He spent most of his time hiding in a corner, until he [[TookALevelInBadAss took a level in badass]].
%%* GuileHero
* HeelFaceTurn: Beginning in [=SG1=]'s PoorlyDisguisedPilot for Atlantis, when he realizes what an absolute tit Kinsey is, and arguably reaching a head in Inquisition, when he goes into the field solo to defend the team.
* HiddenDepths: Becomes more apparent over the course of his time in command, particularly in "The Shrine".
* ObstructiveBureaucrat: Though he becomes one less and less during his time in command.
%%* StraightMan
* StrawCivilian: Eventually grows out of it, but it takes longer than for Weir. This probably has to do with the fact that he was cast as an antagonist on SG-1, so he needed to be given a redemptive arc.
* {{Transplant}}: Just like Rodney, he first appeared in a couple of ''Series/StargateSG1'' episodes.

[[/folder]]

[[folder:The Atlantis Expedition - Recurring characters]]

!!Dr. Radek Zelenka (David Nykl)

Atlantis' number two scientist. Exists primarily to discover impending Wraith attacks and take abuse from [=McKay=].

Associated tropes:

* BeleagueredAssistant: Is constantly put upon by Dr. [=McKay=] and often acting as his helper/second fiddle, despite the fact that he's still the ''2nd top scientist'' in an organization full of Earth's best and brightest.
* BilingualBonus: Speaks a lot of Czech.
* BreakingTheFourthWall: He says the following in Czech at one point: "Jesus, I can't work with these actors!"
* CrouchingMoronHiddenBadass: While under the influence of an amnesia virus (as was most everyone else), he successfully evaded the Marines and ''took one out'' to boot.
%%* {{Foil}}: Definitely one to [=McKay=].
%%* ForeignCussWord
%%* ForeignLanguageTirade
%%* GeniusDitz
* HomelessPigeonPerson: Is a major pigeon enthusiast, having raised pigeons back on Earth.
* TheKlutz: He's not ''that'' big a klutz, but it is noticeable.

!!Major Evan Lorne (Kavan Smith)
[[quoteright:240:http://static.tvtropes.org/pmwiki/pub/images/lorne_6243.jpg]]
Atlantis' military second in command. Joined the expedition in Season Two.

Associated tropes:
%%* DeadpanSnarker: At times.
* HeroOfAnotherStory: He first appeared in SG-1, then he popped up now and again afterwards.
%%* MajorlyAwesome
* MauveShirt: Security personnel who managed to survive to the end of the series.
* NumberTwo: He's implied to be second-in-command of the military personnel, but he is not TheLancer.
%%* SixthRanger
* {{Transplant}}: First appeared in the ''SG-1'' episode "Enemy Mine".

!!Colonel Steven Caldwell (Mitch Pileggi)

Commander of the ship the ''Daedalus''. Not officially a member of the expedition, but definitely someone they can always depend on.

Associated tropes:
%%* BaldOfAwesome
%%* ColonelBadass
* DevilInPlainSight: [[spoiler: See Driven To Villainy, below.]]
* DrivenToVillainy: [[spoiler: Thanks to the Goa'uld spy symbiote implanted in him against his will. He gets better after it's excised, though.]]
%%* FakeGuestStar
%%* ReasonableAuthorityFigure

!!Chuck (Chuck Campbell)

Canadian technician who works in the Atlantis Gate room.

Associated tropes:
* DeadpanSnarker: Feels like Woolsey doesn't show him the respect he deserves and snarks about it.

!!Sergeant Bates (Dean Marshall)

Atlantis' head of security in Season One. Later discharged and became an IOA agent.

Associated tropes:
* AntiHero: He's not evil, just an ass.
%%* TheBusCameBack
* FantasticRacism: Makes it very clear he doesn't like the Athosians.
* {{Jerkass}}: He must have written the book on being a jerkass.
* ProperlyParanoid: Immediately comes to the conclusion that Teyla was giving away their position to the Wraith. He actually was ''right'', sort of. Turned out her father's pendant had been implanted with a tracking device.
* TheStoic: To the point of being ''more'' grim than '''Ronon Dex'''!

!!Dr. Peter Grodin (Craig Veroni)

British scientist who runs the control tower. KilledOffForReal at the end of Season One.

Associated tropes:
%%* KilledOffForReal
%%* MissionControl
%%* SacrificialLion
* YouShallNotPass: [[spoiler:Tried using Ancient tech to stop the Wrath in their tracks, but he was only able to take out one ship out of three.]]

!!Dr. Kate Heightmeyer (Claire Rankin)

Expedition psychologist. KilledOffForReal in Season Four.

Associated tropes:
%%* AllPsychologyIsFreudian
%%* DeadSerious
* HollywoodPsych: And not very good at it either.
%%* TheShrink
* WrongGenreSavvy: Doesn't seem to realize she's in a world where time travel, alternate realities and people being taken over by alien entities are a ''regular'' occurrence. No, clearly if someone is experiencing something weird, it's all in their head.

[[/folder]]

[[folder:The Wraith]]

!!"Michael Kenmore" (Connor Trinneer)

First Wraith on whom the expedition tested their new gene therapy to turn him into a human. It worked. [[HalfHumanHybrid Partly]].

Associated tropes:
* BigBad: Closest the show had to an individual BigBad.
* EvilutionaryBiologist: Tried to kill almost everybody and turn the rest into an unstoppable army of destruction.
* FreudianExcuse: He was betrayed by both humans and Wraith. No wonder he went completely crazy.
%%* HalfHumanHybrid
%%* KilledOffForReal
* NiceJobBreakingItHero: Was your run of the mill Wraith until Atlantis tampered with his genes ([[{{WhatTheHellHero}} twice]], [[IDidWhatIHadToDo without his consent]]). Pretty much turned your average Wraith into a savage Hybrid with a vision of genocidal vengeance and the pure hatred to pull it off. Big mistake, to be sure, but, as Beckett, Weir, and Sheppard point out, they had to try, considering that the Wraith possess every major advantage over Atlantis (with the possible exception of technology, since most of Atlantis' really high-tech goodies are either Ancient or Asgard).
* NotSoDifferent: Likes to think that the Wraith and Atlantis team are basically the same, and seems to say it at least once in every episode he appears in.
* ThenLetMeBeEvil: Was a Wraith who the protagonists forcibly converted into an amnesiac human. His introductory episode has the characters mistreating him for no clear reason, before he realizes that he's a TomatoInTheMirror and breaks out to return to his people... but they won't accept him either, since he's still partly human. He desperately returns to the protagonists and offers valuable aid, just begging them that they don't de-Wraithify him again. They do, and when he recovers, he's fed up of saying WhatTheHellHero, and he snaps completely and becomes an EvilutionaryBiologist.
%%* OmnicidalManiac
* VillainousCrush: For Teyla, possibly the only being ever who showed him compassion, once. This didn't stop him from trying to kill her a half-dozen times throughout the series and trying to harvest her child, however.
* WhatTheHellHero: Calls them out on their actions, repeatedly.

!!"Todd" (Christopher Heyerdal)

A Wraith scientist who was imprisoned alongside Sheppard and was made to feed on him. Different than other Wraith in that he actually keeps his end of the bargains and isn't particularly malicious towards the expedition, finding that they make useful temporary allies.

Associated tropes:
* AffablyEvil: Well, depending on the definition of "evil", but nails the "affably" part pretty well.
* BackhandedCompliment: Agrees that [=McKay=] is highly intelligent... ''for a human.''
* DeadpanSnarker: If he wants to, he can be pretty snarky.
--> '''Ronon''': We're just gonna blow it up.
--> '''Todd''': ''(resigned)'' Naturally. ("The Last Man")
* DefectorFromDecadence: When the expedition came up with a way to remove the Wraith need to feed on humans, he was willing to try it. Didn't quite work out, though, mostly because he wasn't willing to do it on their schedule.
* EnemyMine: Isn't afraid to turn to the Atlantis crew if they have a mutual enemy, but often does it to suit his own interests...
* {{Expy}}: Of Ba'al from ''Series/StargateSG1''. AffablyEvil that occasionally slips into FriendlyEnemy territory? Check. [[EnemyMine Willing to work with the main characters if it's in his best interests?]] Check. DeadpanSnarker from a race with NoSenseOfHumor? Check. Down to earth character from a race of [[LargeHam large hams]]? Check. [[RoyalsWhoActuallyDoSomething In command of a large force but prefers a hands-on approach?]] Check.
* FriendlyEnemy: Comes across as one to Sheppard and [=McKay=] when they're [[EnemyMine forced to team up.]]
* HandshakeRefusal: Intentionally invoked this by offering his hand forward to Woolsey and causing everyone in the vicinity to immediately raise their weapons. Turns out he was just [[{{Troll}} screwing with them]].
--> '''Todd''': *''Laughs''* Just a bit of Wraith humour.
%%* NobleDemon: Probably Stargate's best example.
* ReallySevenHundredYearsOld: It's revealed in "The Lost Tribe" that Todd is over ''10,000 years old''. Given [[ChronicBackstabbingDisorder the nature of Wraith society]], the fact he's lasted that long makes this a rather impressive feat.
* ReliableTraitor: He will invariably screw Atlantis over the moment that the tide might turn in his favour. Pointed out by Sheppard when he explains that dealing with Todd feels like walking around with a live grenade in your pocket.
* RoyalsWhoActuallyDoSomething: Even after Todd has built up his forces again, he still deals with a lot of matters personally.
* SoWhatDoWeDoNow: In "First Contact", agrees that while the gene-therapy will mean they are free from their reliance on Humans as food, it's the end of a ''millennia'' of Wraith society and culture, particularly their self-image of themselves as the SuperiorSpecies.
--> '''Dr. Keller''': It's for your benefit too. If you don't have to rely on human feeding, the war would be over.
--> '''Todd''': Perhaps... But then what would we do? ''Who'' would we be?
* WorthyOpponent: Sees the Atlantis crew and Sheppard in particular as one.
