! Characters in the TV series ''Series/{{Alias}}''.

Due to the [[HeelFaceTurn insanely ambiguous]] [[ChronicBackstabbingDisorder nature of every and all characters involved]], they will simply be listed under very broad "Good Guys" and "Bad Guys" - some more, some less obvious than others.

!! The Organizations:
* '''CIA''': The Central Intelligence Agency - The most obvious "Good Guys" in the series, since most of the main cast are affiliated with them.
* '''Alliance of Twelve''': An organized crime collective formed of elite veteran intelligence operatives. They mainly deal with weapons, intelligence and occasional blackmail. The Alliance operates individually via twelve "SD" cells, with only the leaders of each cell acting as "senior partners" of the Alliance itself.
* '''SD-6''': The Alliance SD cell headed by Arvin Sloane. The cell poses as an elite CIA black-ops division, and it's this ruse that Sloane uses to recruit new operatives.
* '''The Man''': A mysterious crime organization headed by the mysterious "Man", they seek to apparently destroy all competition (Alliance of Twelve included) as well as oppose the CIA.
* '''The Covenant''': A terrorist organization formed by former KGB and Central Committee operatives following the fall of the Soviet Union. They are followers of Rambaldi, albeit extremists of the worst kind.
* '''APO''': Authorized Personnel Only - a covert black ops joint task force created by the CIA and Arvin Sloane to put a dampen on international terrorists. In truth, the organization was truly formed for the sole purpose of capturing [[spoiler:Elena Derevko]], the true leader of the Covenant.
* '''Prophet Five''': An extremely powerful organization compromised of twelve individuals, they are essentially a "step-up" of the Alliance of Twelve. Their influence is nearly limitless as it their power. Much like the Alliance, they too operate through individual cells posing as covert CIA installations.
* '''The Shed''': One of Prophet Five's fake CIA cells, led by Gordon Dean and Kelley Peyton.
* '''K-Directorate''': A criminal society founded by former members of the KGB and the Russian Mafia. They are in direct competition with the Alliance of Twelve and FTL.
* '''FTL''': A criminal organization founded by members rooted in Chinese intelligence and the Triad. Despite competing with the Alliance and K-Directorate for nearly as long as the two organizations existed, the entirety of FTL was destroyed single-handedly by Sark.
* '''Followers of Milo Rambaldi''': Anyone who bears the "Eye of Rambaldi" (a tattoo) on their body is a devotee of the prophet and inventor Milo Rambaldi. There are followers of him found in all of the above organizations, but most of them are part of the Covenant.

[[folder: The Good Guys:]]
!!Syndey Bristow

->'''Portrayed by:''' Creator/JenniferGarner

->'''Affiliations:''' SD-6 / CIA / APO

The main character. Looking for a sense of "self-fulfillment" in her life, she was recruited from grad school into what she believed was a CIA black-ops unit called SD-6, but was actually a terrorist organization. Upon learning the truth she joins up with the real CIA to bring down the Alliance from within as a double-agent.
%%* ActionGirl
%%* AmnesiacDissonance: In Season 3.
%%* BabiesEverAfter
* BadassInDistress: She is captured and tortured ''a lot''.
* BrokenBird: Mostly in season one, when she's avenging the death of her fiance and dealing with the double-agent lifestyle.
* CainAndAbel: Sydney and Nadia, who do their best to avert the prophecy that claims this. [[spoiler:Unfortunately, it sort of comes to pass in "Before the Flood", when Nadia is infected by the tainted water and zombified. Sydney doesn't kill her though, and eventually, she recovers.]]
* TheChosenOne: Despite doing her best to tell Destiny to [[ScrewDestiny go screw itself]].
* DeadpanSnarker: Even under ''torture''. A good example is her line in the pilot to Suit and Glasses:
-->''Okay, this is important. Write this down. E-M-E-T-I-B. Got that? Now reverse it.''
%%* DeepCoverAgent
%%* {{Determinator}}
%%* DoubleAgent
* HurtingHero: In Season 3, when she suffers from LaserGuidedAmnesia and a TimeSkip.
* InTheBlood: Sydney has inherited her extreme amounts of badass from both her parents; she has all of Irina's fiery temper and unpredictability, but tempered by Jack's pragmatism and ability to forgive.
* ManchurianAgent: [[spoiler:Along with the rest of the kids in Project Christmas, Sydney was [[BrainwashingForTheGreaterGood programmed]] to have certain skills and intelligence levels.]]
* TheMasqueradeWillKillYourDatingLife: Literally, with her fiance, Danny. Figuratively with her and Vaughn, before SD-6 is taken down.
%%* MasterOfDisguise
* MsFanservice: Played straight, subverted, zigzagged, and ''weaponized'' in any given episode.
* {{Omniglot}}: *deep breath* Is at least conversant in Russian, German, Greek, Dutch, French, Italian, Spanish, Portuguese, Norwegian, Swedish, Romanian, Hungarian, Hebrew, Uzbek, Arabic, Persian, Urdu, Indonesian, Cantonese, Mandarin, Japanese, Korean, Hindi, Vietnamese, Polish, Serbian, Czech, Ukrainian, and Bulgarian.
* PrettyInMink: Has worn a few furs when going undercover, often as a {{socialite}}.
-->"Don't touch the fur... all right, you may touch the fur, ''once''.
* RealLifeWritesThePlot: Sydney is [[spoiler:pregnant in season five because Jennifer Garner was]].
%%* SheFu
* TeethClenchedTeamwork: This is her default state. She's always being forced to work with somebody that she'd really, really like to kill.
* TheyDo: [[spoiler:With Vaughn.]]
* TooDumbToLive: In "Nocturne," she gets exposed to a hallucinogenic drug and conceals her condition from the rest of APO because she doesn't want to be removed from the field. As a reasonable person would expect, this puts her and the rest of her field team in danger when the drug's effects start to get worse.
%%* WhenYouComingHomeDad
%%* WigDressAccent:
* YouCantFightFate: She's still TheChosenOne.
* YouGottaHaveBlueHair: Along with every other color under the sun, thanks to dye and wigs. One of Sydney's most iconic looks is her blue hair and fetish getup from the season one finale.

!!Jack Bristow

->'''Portrayed by:''' Creator/VictorGarber

->'''Affiliations:''' SD-6, CIA, APO

Sydney's father and Sloane's "former best-friend", also a double-agent for the CIA. A legendary game-theorist and strategist, Jack is excellent at espionage but crap at personal relationships - this has led to a rather soured social relationship with her. The one thing that will always be true however is that he has Sydney's welfare at heart, and ''be damned'' if anyone gets in the way of him protecting her.
%%* ActionDad
%%* AntiHero
* BadassBookworm: The best game-theorist and strategist in the world. Will totally wring your scrawny neck and beat the snot out of you, should he feel the need. He wears a BadassLongcoat
* BerserkButton: Go ahead, [[PapaWolf threaten his only daughter]]. See where it gets you.
* BrutalHonesty: As [[http://www.youtube.com/watch?v=a0qaIvb3bGA&feature=related a hilarious scene in the pilot]] first demonstrates.
%%* TheChessmaster
%%* DarkAndTroubledPast
* DatingCatwoman: Between seasons two and three, when Irina was a traitor and Jack was suspected of it too. It was really all about [[spoiler:teaming up to find their daughter]].
* DeadpanSnarker: It comes out of ''nowhere'', and is usually directed toward people he doesn't like. Basically, if he's cracking jokes, you're four ways ''fucked'' - or already dead.
* DisappearedDad: Emotionally, not physically. After Laura's death, he didn't know how to deal with a small child ''and'' being a spy, so he kept Sydney at arms' length.
* DoubleReverseQuadrupleAgent: Jack ostensibly works for the CIA while keeping tabs on SD-6/whatever Sloane is up to/whatever Irina is up to. Ultimately, he's out for one person: Sydney.
* FriendshipMoment: Any time he figured out that Vaughn or Will or Marshall wasn't just a waste of space.
** One of the most heartwarming is his hugging Will in return after [[spoiler:trading a Rambaldi artifact for Will's life and saving Will from torture]]. It's still awkward and Jack doesn't quite like the guy, but he's important to Sydney and worth saving.
** He and Sloane occasionally had these. There was a great one that zigzagged the trope all over the map in season three, when Jack helps Sloane fake his own death and they share a bottle of the same wine Sloane [[spoiler:used to fake his wife's death two years ago]].
* GiveHimANormalLife: What he tried to do for Sydney. He later tells Sloane that the moment Sloane recruited Sydney into SD-6 was the moment he decided to betray Sloane.
%%* GuileHero
* JackBauerInterrogationTechnique: So many times he's probably the proto-example.
* HeWhoFightsMonsters: Has always been willing to do "whatever it takes" to protect his family. Irina's deception and faked death turned that UpToEleven.
%%* JerkassFacade
%%* KnightInSourArmor
%%* KnightTemplarParent
* TheLancer: To his daughter Sydney.
* NoSocialSkills: He simply just doesn't see the need for them.
* NotSoStoic: When it comes to his daughter, and to a lesser extent, his wife.
* OverprotectiveDad: As Vaughn is constantly finding out, there isn't a limit to how far Jack will go to protect his daughter.
* PapaWolf: Never '''ever''' harm Sydney. He once [[spoiler:shot his own wife]] because he believed they were trying to kill Sydney.
* PerpSweating: Don't make Jack interrogate you. Just tell him what he needs to know.
* RoaringRampageOfRevenge: Goes into kill mode when someone threatens Sydney.
%%* TheSpymaster
* TakingYouWithMe: His now-iconic [[spoiler:[[OutGambitted response]] to Sloane attaining immortality]].
-->''You beat death, [[spoiler:Arvin]]. But you couldn't beat me.''
%%* TeamDad
* TheMasochismTango: Irina marries Jack for his secrets, he [[spoiler:brainwashes their kid]], she fakes her own death, he becomes a bitter shell of a man, she betrays him to Sloane and [[spoiler:is doubled]], he [[spoiler:shoots her double in the head]], she gets better and comes after him, he forces her out of a building at gunpoint . . . and so it goes.
* TheStoic: Most of the time.
* TokenEvilTeammate: Perfectly willing to murder and torture to get the job done, particularly if the job involves protecting Sydney.
* TortureTechnician: A rare heroic example. His talent for torture is never presented as anything less than the vicious, horrible thing it is. When you really have to worry is when he's cracking jokes right and left.
-->'''Jack''': I'm actually hoping you don't tell us what we need to know. There's a 50/50 chance Sydney cuts the right wire. I'm willing to take those odds if it means I can stand here and watch you turn into an animal.
-->'''Elena''': You're not a gambling man, Jack.
-->'''Jack''': I didn't used to be, but it's been a rather interesting year for me. It's lead me to reevaluate my life. I'm trying to have more ''fun'' these days.
* TriangRelations: #9 with Irina and Katya (but not at the same time), #8 with Irina and Sloane (but ''not'' a triad situation, Irina was married to Jack but had an affair with Sloane, who was Jack's best friend).

!!Michael Vaughn / Andre Michaux

->'''Portrayed by:''' Michael Vartan

->'''Affiliations:''' CIA / APO

Sydney's CIA handler, who very quickly falls for her. Vaughn's father was also an agent, killed by Irina Derevko on a mission he didn't even agree with. [[spoiler:It's later revealed this is only a half-truth. His real name is Andre Michaux, and both he and his father have been working all their lives to bring down Prophet Five - the real reason for his father's death.]]
%%* BabiesEverAfter
* DeadPersonImpersonation: We find out in season five that [[spoiler:Vaughn's real name is Andre Michaux, and his father wasn't working for the CIA, but rather, Prophet Five.]]
* EveryoneLooksSexierIfFrench: [[spoiler:Technically he's Creole, but he's fluent enough in French to come off as a native.]]
%%* FakingTheDead: [[spoiler:In Season 5.]]
%%* TheHandler
* HeroicBSOD: [[spoiler:Lauren's betrayal and double-agent status pushes Vaughn over the edge. He becomes obsessed with hunting her down, and in the S3 finale, kills her in cold blood.]].
* TheMasqueradeWillKillYourDatingLife: With Sydney in S1 to "Phase One".
%%* NiceGuy
* TheyDo: [[spoiler:With Sydney.]]
* TooDumbToLive: He survives, but standing there and looking at Sydney running from a wall of water in the season one finale was ''stupid''. It's his own fault he gets trapped.
* TookALevelInBadass: Being betrayed by the woman you thought was your wife and a fellow agent will do that to you. Luckily, when your co-worker and future father-in-law has been through the same thing, he can help with the coping mechanisms and provide excellent weaponry.
* VitriolicBestBuds: With Weiss, to HoYay levels.

!!Marcus Dixon

->'''Portrayed by:''' Creator/CarlLumbly

->'''Affiliations:''' SD-6 / CIA / APO

Sydney's field partner at SD-6 and one of her closest friends, she struggles with lying to him the most when she becomes a double agent. When SD-6 falls, Dixon reluctantly joins the real deal, and rises through the ranks to become Director of the CIA's Joint Task Force.
* AchillesInHisTent: His initial attempt to cope with the truth about SD-6 and Sydney's double-agent status is to cut off all ties with his former team, the intelligence world and Sydney in particular to the point of refusing to get involved even when his personal knowledge is vital for a mission. Only when Sydney gets captured trying to replace him does he throw off his anger and save the day.
* BewareTheNiceOnes: Dixon should provide the page image.
* CoolOldGuy: Does pretty well for himself as a field agent.
%%* GeniusBruiser
* HappilyMarried: Is the resident family man of the show.
* HeroicBSOD: After [[spoiler:the death of his wife at Sloane's hands, Dixon goes rather spectacularly off the rails. He starts popping Vicodin, almost tortures a man to death, and then tricks the entire CIA into thinking he's going to blow himself and a mook up to get Sloane's whereabouts.]] He gets better, though.
* IntergenerationalFriendship: With Sydney.
* TheMentor: To Sydney.
%%* OlderAndWiser
* {{Omniglot}}: Speaks nine languages, but "techno isn't one of them".
%%* ReasonableAuthorityFigure
* ScaryBlackMan: Subverts it - Dixon is the most level-headed guy around. Except for that one time he went off the rails due to [[spoiler:his wife's death]].
* TheSpymaster: Upon his promotion to JTF Director.
%%* TokenMinority
* TragicMistake: In "Truth Takes Time", Dixon serves as a CIA sniper on the assault on Sloane's villa. He [[spoiler:accidentally shoots Emily Sloane, who had been helping the CIA, instead of her husband.]] Later, Sloane takes revenge by [[spoiler:having Diane Dixon killed]].

!!Marshall Flinkman

->'''Portrayed by:''' Kevin Weisman

->'''Affiliations:''' SD-6 / CIA / APO

The resident technical wizard for SD-6, and later, the CIA. Marshall's gadgets and knowhow make him a good guy to have around . . . if you can get him to stop babbling.
* BunnyEarsLawyer: Always comes through when you need him, whether it's hacking into a government facility at gunpoint or taking on a ''solo'' mission to save Sydney from being buried alive.
* ADayInTheLimelight: "Tuesday" (the episode in which the mission to rescue Sydney mentioned above takes place).
* GibberingGenius: The [[Franchise/JamesBond Q]] of this universe, complete with MotorMouth tendencies out the wazoo.
%%* MissionControl
%%* MotorMouth
* NonActionGuy: Uses his brains, not his brawn.
* OddFriendship: With Rachel in season five.
* PhotographicMemory: A very useful thing to have for a computer and gadget genius.
%%* PluckyComicRelief
%%* TheSmartGuy
%%* TechnoWizard
* VerbalTic: Talks like Creator/JeffGoldblum.

!!Eric Weiss

->'''Portrayed by:''' Creator/GregGrunberg

->'''Affiliations:''' CIA / APO

Vaughn's best friend, and later Sydney's. A CIA agent great with a sarcastic quip in a crisis, he's also one of the most reliable guys on the team.
* AscendedExtra: Was only meant to have a nonspeaking bit part in the pilot as a favor to Grunberg from his best friend, Creator/JJAbrams. He eventually became a recurring character in the first two seasons, and a full-fledged regular in seasons three and four.
* BadassNormal: While he is a CIA agent, Weiss is usually on backup support. Doesn't mean he can't or won't kick your ass.
* BetaCouple: With Nadia in season four.
%%* BewareTheNiceOnes
* TheBusCameBack: He returns for a guest appearance or two down the road.
%%* DeadpanSnarker
* {{Foil}}: To Vaughn, for much of seasons one and two.
%%* NonActionGuy: In season one.

* PromotionToOpeningTitles: Was upped to series regular in season three...
* PutOnABus: Left the show at the start of season five.
* TookALevelInBadass: Apparently being shot by Irina Derevko was the last straw. Weiss stops being a NonActionGuy and becomes a BadassNormal.
* VitriolicBestBuds: With Vaughn, usually to HoYay levels.

!!Will Tippin

->'''Portrayed by:''' Creator/BradleyCooper

->'''Affiliations:''' CIA

Sydney's best friend, a reporter who begins piecing together the strange circumstances surrounding Danny's (Sydney's fiancee) death. He eventually becomes an analyst for the CIA after Vaughn picks up on his talents.
%%* ActionSurvivor
* BadassBoast: ''"One in five, bitch! ONE IN FIVE!!!"''
%%* BewareTheNiceOnes
* CommutingOnABus: Goes into Witness Protection after [[spoiler:Evil Francie / Allison Doren tries to kill him]], returns once in season three and once in season five to go on one-off missions with Sydney.

* RecklessSidekick: In season one. He gets better.
* TemporaryLoveInterest: He and Sydney try hooking up in both season one and season three - neither time really works, and they decide they're BetterAsFriends.
%%* UnfazedEveryman

!!Assistant Director Kendall

->'''Portrayed by:''' Creator/TerryOQuinn

->'''Affiliations:''' FBI / CIA / Followers of Rambaldi

In charge of the FBI/CIA Joint Task Force and Operation "Bring Down the Alliance", he's something of an antagonist to Sydney due to his by the book approach. Turns out he's the best kind of guy, going out of his way to protect Sydney for nearly two years after she was captured and brainwashed. It was then revealed that he was not just a FBI agent, but the director of the Department of Special Research, specializing in keeping many of Rambaldi's artifacts safe. It was through his and Sydney's combined efforts during her two "missing years" that they uncovered most of his artifacts and kept them safe.
* BaldOfAwesome: Evolves into this in S3.
* FakeGuestStar: Despite appearing in nearly every episode of season two.
* JerkWithAHeartOfGold: [[spoiler:Not nearly as big as Jack's, but still a very decent guy given his complete asshole facade]].
* MrExposition: Nigh constantly. An entire ''episode'' is devoted to Kendall interrogating Sydney and recapping what we know about the series.
* NoNameGiven: We never learn his first name.
* ObstructiveBureaucrat: [[spoiler:On the surface]].
* PointyHairedBoss: Despite being bald, Kendall fits.
* TookALevelInBadass: After the events of season two. A couple years and a demotion drive him to [[spoiler:save Sydney]] and do what ''no one else in the series'' is apparently capable of - [[spoiler:tell her the complete truth about who he is, who he works for, and what happened to her during those missing two years]].

!!Nadia Santos

->'''Portrayed by:''' Creator/MiaMaestro

->'''Affiliations:''' APO

Sydney's long-lost sister, who grew up in an orphanage in Argentina and was secretly watched over by her Aunt Elena. Worked for Argentinian intelligence before joining APO. She is in fact Sydney's half-sister, with her father being Sloane. And for some reason, she's the key to unveiling one of Rambaldi's endgames through the injection of "Rambaldi fluid" as well as a key to one of his prophecies - the one in particular where she and Sydney are forced to fight.
%%* ActionGirl
* BetaCouple: With Weiss.
* BrainwashedAndCrazy: What Elena does to her after drugging her and activating a giant Mueller Device
* CainAndAbel: She and Sydney are prophesied to end up like this. [[spoiler:It comes to pass when Nadia is infected with the tainted water and zombified, then set upon Sydney by Elena, but she eventually recovers.]]

%%* TheIngenue
%%* KilledOffForReal
* MadScientistsBeautifulDaughter: Right down to the HeelFaceTurn.
* SealedInsideAPersonShapedCan: Apparently, only the child of two Rambaldi devotees can be a [[spoiler:"direct conduit" to Rambaldi himself]]. Nadia is abused by both parents for this ability.

%%* WaifProphet

!!Rachel Gibson

->'''Affiliations:''' The Shed / APO

A young analyst who worked for The Shed before learning that it was really a branch of [[WesternTerrorists Prophet Five]]. She was then rescued by Sydney and brought into APO with Sydney as her handler.
* DatingCatwoman: Subverted. She's attracted to Sark when she thinks he's a civilian, but wants nothing more to do with him after learning he's with the bad guys.
%%* NaiveNewcomer
* OddFriendship: With Marshall.
* PluckyGirl: Probably would have morphed into a full ActionGirl (like everybody else) if the show had lasted long enough. As it is she's not much of a fighter, but she does her best.
* SuspiciouslySimilarSubstitute: A twenty-something girl approached by what she believes to be the CIA but is actually a terrorist organization headed by an evil mastermind. She then joins up with the real CIA to bring her former employers, who have hurt people she loves, down. '' Remind you of anybody?''
* UndercoverAsLovers: With Sark, at one point.
* UnresolvedSexualTension: With Sark, of course.
* TookALevelInBadass: Starts out as a mousy analyst, and eventually becomes a field capable agent.

->'''Affiliations:''' APO

Brash, snarky agent who joins APO after Weiss leaves. His wife was killed years ago by an enemy agent, and seeing APO as golden resource decides to chase after revenge.

%%* HeroicSacrifice
%%* LeeroyJenkins

!!Emily Sloane

->'''Affiliations:''' ''None''

Arvin Sloane's beloved wife and a mother figure to Sydney who is dying of cancer. She reveals to Sydney that she's always known Sloane wasn't a businessman and knows about SD-6. [[spoiler:After faking her own death with Sloane's help, she ultimately decides to act as an informant to the CIA on his illicit activities, no longer able to keep it to herself. At the last minute, however, she retracts the decision and decides to stay with Sloane - right up until Dixon accidentally shot her]].

* FakingTheDead: [[spoiler:She has her death staged by Sloane after he's ordered to kill her for uncovering the truth behind SD-6.]]
%%* IllGirl
* HiddenDepths: Turns out Emily isn't just a BrokenBird victim of Sloane: [[spoiler:she helped Sloane fake her death, [[{{Fingore}} cut off her own finger]], and was prepared to betray him in exchange for his not receiving the death penalty. She stays loyal to him at the end, but [[ThePowerOfLove can you really blame her]]?]]
%%* KilledOffForReal
* MoralityPet: For her husband. Every good thing Sloane ever does is either for or about her.
* ParentalSubstitute: Sydney says that she has always regarded Emily as a mother to her.

[[folder: The Bad Guys:]]
!!Arvin Sloane

->'''Portrayed by:''' Ron Rifkin

->'''Affiliations:''' The Alliance of Twelve / SD-6 / APO / Prophet Five

The ultimate BigBad of the series. [[HeelFaceRevolvingDoor An SD-6 cell director and member of the Alliance, then allied with Sark and Irina, then headed up APO]]. An obsessive devotee of Milo Rambaldi, Sloane will do anything to further his own endgame, which for years was unknown, until it was revealed to be [[ImmortalitySeeker immortality]].
* AbusiveParents: He shuffles between this and KnightTemplarParent with alarming frequency.
* AndIMustScream: [[spoiler:His fate is eternal life, but trapped alone and underground, unable to die. That's what you get when you try to [[OutGambitted out-gambit]] Jack Bristow.]]
* AffablyEvil: He's a perfectly nice guy...until you cross him.
* ArchEnemy: Sydney considers him as such.
* ArtificialHuman: [[spoiler:Has a double, [[FanNickname nicknamed "Arvin Clone"]].]]
* TheAtoner: He ''genuinely'' becomes one of the good guys (if not completely distrusted) at the start of the fourth season, and does what he can to atone and find the GreaterScopeVillain [[spoiler:Elena Derevko]]. Unfortunately, it just wasn't meant to be.
* BenevolentBoss: He is genuinely fond of his employees, and still regards ex-ones like Jack and Sydney with respect even after he finds out that they really ''were'' [=CIA=] and had been working to bring him down.
** In one early episode Sark compliments him on the genius of running a fake government agency and having duped pretty much everybody working for him; Sloane is offended and warns him to never insult his people again, or take them for idiots.
** In another, he advocates going after The Man with everything the Alliance has got mostly because The Man attacked SD-6 and killed some of his people.
** On the other hand, sometimes harshly subverted, as when he is perfectly willing to abandon Marshall to be tortured to death when he's captured by Sark's men.
%%* BetterTheDevilYouKnow
* BigBadDuumvirate: With [[spoiler:Irina Derevko]] in Season 2 and Season 5.
* TheChessmaster: The embodiment of this trope in the ''Alias'' universe.
* ChronicBackstabbingDisorder: If you want Arvin Sloane to work for you, just put him in charge of your organization and kill yourself now. It'll just save everyone time in the long run.
* TheComicallySerious: This man has absolutely ''no sense of humor whatsoever.'' He can't suffer the core group's shenanigans for more than a few seconds. That said, the other characters are more than happy to poke fun at him whenever they feel they can get away with it, ''much'' to his distaste and displeasure.
* CoolOldGuy: He's not as combat capable as he was in his younger days, but he's still one tough old bastard, as [=McKenas=] Cole discovers.
* DiabolicalMastermind: The series' best example. He ends up running three or four {{NebulousEvilOrganization}}s in a row.
* EvenEvilHasLovedOnes: Dearly loves his wife, Emily.
* EvilCounterpart: To Jack. After 4 seasons of supremacy, he is OutGambitted rather magnificently.
* EvilFormerFriend[=/=]FallenHero: He and Jack were best friends when working at the CIA.
* FalselyReformedVillain: During seasons three and four.
* FriendlyEnemy: He tries mightily for this, but Sydney and Jack shut him down at every opportunity.
* HeelFaceRevolvingDoor: He works for everyone at some point or another. (Except the Covenant. He was just undercover on that one.)
* HeroKiller: Although, admittedly, it does take him until almost the series finale to kill someone listed in the opening credits.
* ItsPersonal: With The Man for attacking SD-6 and killing some of his people.
* JokerImmunity: To the extent that he survives [[spoiler:''his own execution'']] in Season 3.
* KlingonPromotion: He (somehow) assumes control of Prophet Five's assets by [[spoiler:having Kelly Peyton assassinate the Twelve]].
* ManipulativeBastard: Extraordinarily skilled in this regard, rivaled only by [[spoiler:Irina]].
* TheMole: Or so he claims to be, in regards to his apparent FaceHeelTurn of teaming up with Elena in season four. He says he only allied himself with her to save Nadia and undermine Elena, but [[HeyYouHaymaker Jack doesn't particularly care for the details]].
* MoleInCharge: Of APO. No one really believes his intentions are good, but [[spoiler:poisoning the world's water supply]] in the name of keeping his cover is a bit too much devotion.
* MoralMyopia: Regarding [[spoiler:his wife]]'s death.
* NotMeThisTime: He had nothing to do with [[spoiler:Sydney's disappearance]] and had no involvement in the Covenant until he was recruited to infiltrate them for the CIA. Doesn't stop Sydney from constantly accusing him of being the secret mastermind behind it all.
* OffingTheOffspring: [[spoiler:He accidentally kills his own daughter.]]
* PetTheDog: Any of his scenes with Emily, whom he truly loved, and a few times with Nadia.
* RevengeByProxy: [[spoiler:Dixon accidentally kills Emily, so Sloane has someone rig Diane Dixon's car with a bomb and has her killed]].
* SanitySlippage: After accidentally killing [[spoiler:his own daughter]], he starts hallucinating that she's still alive and talking to him.
* TheSpymaster: Inarguably the best in the business: [[spoiler:as he is pardoned and hired by the CIA to lead a covert branch that resembles SD-6]]
* TheStarscream:
** When the Alliance orders him to kill his wife, he [[spoiler:fakes her death, scams them out of $100 million, manipulates the CIA into taking them down, then goes off to [[StartMyOwn start his own crime syndicate]]]].
** He decides to get out ahead of Prophet Five's inevitable exercise of YouHaveOutlivedYourUsefulness by [[spoiler:sending Kelly Peyton to wipe out the Twelve]].
* TragicVillain: He was a complete bastard until he became TheAtoner. Following [[spoiler:Nadia's death]], he became this.
%%%%* WhoWantsToLiveForever:
* WhyAreYouNotMySon: He served as Sydney's guardian angel during Jack's long absences while she was growing up, and he considers her to be a substitute for the children he never had. She...does not take this attitude well.
%%* WickedCultured

!!Julian Sark

->'''Portrayed by:''' Creator/DavidAnders

->'''Affiliations:''' The Man / SD-6 / The Covenant / Prophet Five / Followers of Rambaldi

The mysterious and cultured young lieutenant to "The Man." A clever criminal and "businessman" with self-described "flexible loyalties," he'll switch ''several'' different sides at the drop of a hat. No one's really sure ''what'' he wants, but according to him, he just wants to be on the "winning end."
* AffablyEvil: He is usually polite and almost never raises his voice. He even says "please" and "thank you" during very tense situations.
* AmazonChaser: He is very attracted to {{action girl}}s. He was romantically involved with badass females such as Allison Doren and Lauren Reed, plus he has a long-running crush on Sydney Bristow. The more these ladies showcase their skills, the more turned on he is.
* AntiVillain[=/=]NobleDemon: Depends on the year, month, week, day, and hour.
* BadassInANiceSuit: It's part of his professional, no-nonsense image.
* BastardUnderstudy: He considers Irina Derevko to be a mentor.
* BelligerentSexualTension: With Lauren Reed.
* BetaCouple: With Allison Doren. He also has an on-again, off-again relationship with Lauren Reed.
* BigBadDuumvirate: Shares the seat with Lauren Reed in Season 3.
* BlueAndOrangeMorality: Due to a severe case of ChronicBackstabbingDisorder, Sark very easily comes off like the least trustworthy person in the entire series. That being said, he ''does'' have a code in there somewhere, and there's an entire episode ("A Man of His Word") devoted to showcasing him to be a person, who at the very least, keeps to his promises.
** This particular episode, if not anything else, also portrays him as a NobleDemon. [[HeelFaceRevolvingDoor That being said...]]
* BreakoutVillain: Sark was supposed to be a one-off character, a gofer for K-Directorate or Irina or the Alliance. Fan reaction to David Anders was so great that he became more and more high-profile, eventually taking over the BigBad mantle [[spoiler:in the series finale flash-forward]].
* CoolShades: Stylish sunglasses are his favourite fashion accessories.
* CulturedBadass: His appreciation for the finer things in life doesn't make him any less dangerous.
* DeadpanSnarker: Even when he's weaponless, he's still armed with plenty of quips.
* DiabolicalMastermind: He tries to be one, but even when he becomes a DragonAscendant, he never really rises above being the top lieutenant to someone bigger than he is.
* TheDragon: To Irina mostly, and to a lesser extent Arvin in Season 2. And later, DragonAscendant.
* DrinkOrder: He prefers the pricey and rare Chateau Pétrus 1982 (a fact that the Covenant [[YourFavorite is aware of]]), which is a strong indication of his sophisticated tastes.
** He also has a fondness for high-end champagne. He even nonchalantly pops off the cork from the bottle while ''[[TheUnfettered completely surrounded by numerous agents with lots of guns]].''
** When he adopts the alias of Bob Brown, an American, he orders beer at the bar. This choice of drink is supposed to hint that Bob is middle-class, unlike Sark's posh Englishman routine.
* EvenEvilHasStandards: He finds Bomani's cavalier exercise of YouHaveOutlivedYourUsefulness to be "extravagant."
* EvenTheGuysWantHim: In "No Hard Feelings," an Italian prisoner (who is presumably experiencing SituationalSexuality) licks his lips at the sight of [[PrettyBoy Sark]], and tells the young man that he will be [[PrisonRape very popular here]]. When Sark fakes a seizure, the Italian cell mate then calls out for help by shouting, "The beautiful man is dying!"
* EvilCounterpart[=/=]{{Foil}}: To Agent Vaughn. Just as Michael was Sydney's handler, Julian also served the same role to Allison; both men then developed a romantic relationship with their charge. Vaughn and Sark are also attracted to the same two women (i.e. Sydney and Lauren), which resulted in a [[LoveDodecahedron "love square"]] in Season 3.
* TheHandler: He is this to Allison Doren in Season 2.
* TheHeavy: In both Seasons 2 and 3.
* IAmVeryBritish: Very posh, but not once does he ever come across as forced or unnatural.
* ImprobableAge: Becomes the head of a multi-billion-dollar international crime syndicate while still in his early twenties.
* JokerImmunity: It's a RunningGag.
* KarmaHoudini: [[spoiler:Still free and pulling capers as of the DistantFinale.]]
* LastNameBasis: He's always Sark or Mr. Sark. His first name isn't even revealed until Season 3.
* ManlyTears: He visibly and audibly sobs after he sees [[spoiler:Lauren's corpse]].
* ManOfWealthAndTaste: He's impeccably groomed and enjoys wearing elegant, tailored suits along with expensive shoes.
* MouthOfSauron: For "The Man" in Season 1.
* MrFanservice: He appears shirtless in a few scenes, which is no doubt for the benefit of his numerous fangirls.
** In Season 3's second episode, Sark speaks to Sydney from a CIA cell. Is a form-fitting black t-shirt really standard prison garb for international terrorists? Probably not, but ''[[RuleOfSexy it's Sark.]]''
* NervesOfSteel: He handles most situations with cool professionalism and a few choice quips. A few scenes go out of their way to show his obscene self-confidence:
** In Season 2, Sydney sees him standing behind some (bulletproof) glass and shoots at him multiple times. He doesn't even flinch.
** It happens again in Season 3.
** In Season 4, he lures a CIA assault team to an empty building in order to make a deal. Facing nine very tense men aiming rifles at his head, he calmly ''pops the cork off a champagne bottle.''
* NoNonsenseNemesis: Sark is very efficient when he carries out his own or his employers' plans.
* NotMeThisTime: He didn't have anything to do with [[spoiler:Sydney's disappearance]].
* PrettyBoy: Lampshaded by Daniel Ryan in "Facade," who had never met Sark face-to-face, but was informed that the young man was a pretty boy.
* PromotionToOpeningTitles: In Season 2.
* SelfMadeOrphan: [[spoiler:After discovering that his father is not only alive but working with Sydney, he has the Covenant assassinate him.]]
* ShirtlessScene: His toned chest is always bare whenever he has a bedroom scene.
* TheStoic: He possesses a calm, controlled demeanour, and rarely displays his emotions in an overt manner.
* TerroristsWithoutACause: Sark's loyalties are to the highest bidder or Irina, whoever gets there first.
* VillainousCrush: He has a thing for Sydney (which he makes clear when Lauren dresses up as her in Season 3) and continues to flirt with Rachel long after she makes it clear that she's no longer interested.
* WeCanRuleTogether: The first time he meets Sydney, he offers her a job.
%%* WesternTerrorists
* WildCard: His loyalties are self-described as "flexible." He admits in the series finale that all he ever wanted was to come out on the winning side.
* WickedCultured: He is always well-dressed, eloquent, and is a connoisseur of fine wine and champagne.
* YouKilledMyFather: He's quite cross with Sydney about it. Until he learns [[spoiler:that he's still alive. Then he kills his father himself]].

!!Irina Derevko / Laura Bristow

->'''Portrayed by:''' Creator/LenaOlin

->'''Affiliations:''' The Man / Prophet Five / Followers of Rambaldi

Sydney's mother, who isn't quite as dead as everyone thinks. She shows up in season two as a prisoner of the CIA and gains Sydney's trust. Irina will always be out for herself, though. She's the real face of "The Man", with Khasinau as her decoy. Despite appearing KIND of benevolent to Sydney, she's arguably the other BigBad in the series, seeking the same thing as Sloane and destroying anyone who gets in her way - be it Sydney or Jack.
* ActionMom: One of the most badass characters in the whole show.
%%* AffablyEvil
* AgentsDating: With Jack. Any time they have to be UndercoverAsLovers (or just married), it's ''hilarious'', due to the inherent awkwardness of her having betrayed him.
* BackFromTheDead: ''Twice''. Once in "Almost Thirty Years", and again in "The Descent".
* BecomingTheMask: Part of the reason she faked her death the first time is because she was too attached to her family. And really, how much of her marriage to Jack was a lie?
* BetterTheDevilYouKnow: Jack comes to regard her in this way - better her than Sloane or the Covenant or other assorted terrorists.
-->'''Irina''': We both know how this is supposed to play out. You bring me back to the States, turn me over to your superiors.
-->'''Jack''': I thought you could reach the border by daybreak.
-->'''Irina''': What about the Agency, what will you tell them?
-->'''Jack''': What I think they already know - that no one can hold on to Irina Derevko for too long.
* BigBad: [[spoiler:As the true power behind "the Man," she was this for Season 1.]]
* BigBadDuumvirate: [[spoiler:With Arvin Sloane in Season 2 and Season 5.]]
* BoxedCrook: For the CIA in Season 2.
* CloningBlues: [[spoiler:Was "doubled" as part of Project Helix. Luckily, the Irina that Jack executes over her attempts to kill Sydney isn't the real one.]]
* DeepCoverAgent: Practically the personification of the trope.
* DeliverUsFromEvil: Subverts and {{lampshades}} the trope. Getting pregnant was an accident, but Irina claims she kept her child because it gave her a greater hold on Jack. She also claims - to Sydney's face - that she could have easily terminated the pregnancy or killed Sydney, but she realized her daughter was innocent. She claims to love Sydney, but that doesn't make Sydney immune from danger at Irina's hands.
* DiabolicalMastermind: Becomes one whenever she's in the "Heel" section of the HeelFaceRevolvingDoor.
* DiedInYourArmsTonight: [[spoiler:Double!Irina and Jack. Subversion, too, as it's ''Jack'' who shot her. TearJerker, too.]]
%%* DiesWideOpen
* DoubleReverseQuadrupleAgent: Out. For. Herself.
%%* EvilMatriarch
* EvilMentor: To Julian Sark. She taught him much of what he knows about the criminal world.
* TheHecateSisters: The Mother, to Elena's Crone and Katya's Warrior/Maiden, despite being the youngest of the Derevko sisters. Due to the importance of Sydney in both the show and to Rambaldi, Irina is definitely coded as the Mother.
* HeelFaceRevolvingDoor: Irina is out, first and foremost, for herself.
%%* KarmicDeath
%%* KnightTemplarParent
%%* LadyOfWar
* TheManBehindTheMan: [[spoiler:Almost literally, since she, and not Khasinau, is truly "the Man."]]
* ManipulativeBitch: Has to have been, considering she lived a lie for eight years and then continued to twist just about everyone, up to and including world governments, around her little finger.
* TheMasochismTango: Irina marries Jack for his secrets, he [[spoiler:brainwashes their kid]], she fakes her own death, he becomes a bitter shell of a man, she betrays him to Sloane and [[spoiler:is doubled]], he [[spoiler:shoots her double in the head]], she gets better and comes after him, he forces her out of a building at gunpoint... and so it goes.
%%* MataHari
* MissingMom: Well, until she comes back.
* MsFanservice: Have you ''seen'' her biceps? S2 had her in tank tops, but her bra-and-panties scene in "Passage Pt. 1" and the leopard-print minidress from "A Dark Turn" definitely qualify as well.
* ParentalSubstitute: Sark considers her to be a mother figure of sorts.
* ShipperOnDeck: In Season 2, she openly encourages the Sydney/Vaughn 'ship.
* ThanatosGambit: "Laura" fakes her death because her superiors at the KGB are growing suspicious of how attached she is to her fake family, Jack and Sydney.
* TriangRelations: #9 with Jack and Katya, #8 with Jack and Sloane (but ''not'' a triad situation, Irina was married to Jack but had an affair with Sloane, who was her husband's best friend).
* TrojanPrisoner: Played with. Irina was the CIA's prisoner for an entire season, and Jack suspected her of precisely this motive - however, she's really playing her own endgame and never overtly betrays the CIA while she's there or uses her intel to harm them after she escapes.

!![=McKenas=] Cole

->'''Portrayed by:''' Creator/QuentinTarantino

->'''Affiliations:''' SD-6 / The Man / The Covenant

A former SD-6 top operative who has a major bone to pick with Arvin Sloane - one of the many reasons he chose to become an agent of "The Man." Despite getting apprehended by the CIA after his successful infiltration of SD-6, he somehow managed to get out and become the second most powerful man in The Covenant - the details of which are a "good story."
%%* AxCrazy
* BadassInANiceSuit: Which [[Film/ReservoirDogs may look familiar]] to Tarantino fans.
* CombatPragmatist: The guy is downright ''efficient'' in his methods, and plans for nearly everything. If it wasn't for [[SpannerInTheWorks Vaughn]] showing up out of nowhere, he would've completely won.
* CurbStompBattle: The first time he fights with Sydney, she doesn't manage to get a ''single'' hit in on him.
* FauxAffablyEvil: He tries to come off as pleasant as Sloane or Sark, but he just can't keep his inner sociopath from coming out when things aren't going his way.
* GeniusBruiser: The ''only'' man who successfully managed to bring SD-6 down to a screeching halt - partly in thanks to his unorthodox BadassCrew.
* ItsPersonal: He has a grudge against Sloane, and clearly allows it to get in the way of his mission.
* KnightOfCerebus: His appearance marks the point where both Sydney and Sloane discover they've got ''major'' competition in the intelligence world.
* LargeHam: Noted in-universe.
-->'''Sloane:''' I can't be the first person to have difficulty taking you seriously, can I?
* MotorMouth: Like pretty much every Quentin Tarantino role ever, the man just can't shut up.
%%* NeverMyFault
* NoodleIncident: When Sark asks him when he was released from CIA custody, all he replies is "That's a good story."
* TortureFirstAskQuestionsLater: He keeps torturing Sloane long after it becomes clear that, first, Sloane isn't going to talk and, second, he doesn't need Sloane's information anyway.
* TortureTechnician: And a pretty damn good one - too bad Sloane's ''really'' good at withstanding torture.
* UnexplainedRecovery: No one knows how he got out of CIA custody to become a ''leader'' of the Covenant. [[NoodleIncident He doesn't like sharing the details either.]]
* UnholyMatrimony: His relationship with Toni is a subversion on both ends. They seem like SickeningSweethearts, but [[spoiler:she's a DeepCoverAgent using him to penetrate the Man's network and he cares so little about her that he hardly blinks after killing her in a fit of rage]].
* VillainousBreakdown: In the second half of "The Box," when his men start disappearing and it becomes clear that Sloane isn't going to break, he throws a temper tantrum that ends with [[spoiler:randomly killing his girlfriend]].
* WhatHappenedToTheMouse: After his appearance in Season 3, which established him as a major player in the Covenant, he was never seen or even mentioned again.

!!Kelly Peyton

The ultimate BitchInSheepsClothing. She was an agent of The Shed, and Rachel's supposed best friend.

After Dean was taken out, she became a member of Prophet Five and served [[spoiler:Irina]] alongside Sark.

!!Gordon Dean

->'''Portrayed by:''' Tyrees Allen

The leader of The Shed, and a member of Prophet Five. Like Sloane, he too used his installation as a ruse for the CIA. Unlike Sloane, he could not keep the deception up as efficiently and was quickly exposed and forced on the run.
* BadBoss: When he finds out that the Prague cell of the Shed has been compromised, he blows up the building...with all of the agents except Peyton still inside.
* BigBad: For the first half of the final season.

NSA agent who marries Vaughn during Sydney's two-year absence. Is later revealed to be a double agent in league with the Covenant and Sark.
* BelligerentSexualTension: With Sark.
* BigBadDuumvirate: With Sark in Season 3.
%%* BitchInSheepsClothing
%%* DarkActionGirl
* DeepCoverAgent: Is actually a double agent working for the Covenant, tasked to marry Vaughn to keep an eye on him, which makes her a {{foil}} for Irina. In contrast to Irina, Lauren doesn't have any feelings for her husband and nothing keeping her from trying to kill him.
* EvilCounterpart: To Sydney, like most of the female villains on the show. Very much Sydney's visual opposite, blonde-haired and blue-eyed and appearing very warm and friendly until she reveals the killer underneath.

!!Elena Derevko

->'''Affiliations:''' The Covenant

The eldest of the Derevko sisters and the leader of the Covenant, she is widely regarded as the worst and most ruthless of them all. Elena watched over Nadia in Argentina because she knew Nadia would become important. She also poisoned the water supply in Svogda to activate a giant Mueller Device, but her plan (somewhat) failed and was eventually executed by Irina.
%%* BigBad: Of Season 4.
%%* BitchInSheepsClothing

!!"Arvin Sloane" / Ned Bolger

->'''Portrayed by:''' Joel Grey

->'''Affiliations:''' The Covenant

The ultimate BigBad of the series. A Covenant cell director, then a member of... Wait, [[FlatWhat what?]]

His real name is Ned Bolger, and he was a U.S. Army corporal with a brainwave pattern staggeringly similar to that of Sloane's. This made him the ideal test subject to ''clone Sloane's brain'' onto a another person. Thus, Bolger actually ''became'' Arvin Sloane. He was programmed as such for several reasons: To access many of Sloane's resources to aid Elena in developing a giant Mueller Device, to frame the real Sloane for many of his activities, and to distract APO and Vaughn long enough to finisher her plan. He was ultimately caught and exposed for what he was - possibly becoming a vegetable.
* ArtificialHuman: [[spoiler:Of a sort. He's real, but his memories isn't.]]
%%* BigBad: [[FlatWhat ...Huh?]]
* BigLippedAlligatorMoment: Practically acknowledged in-universe. Pretty much no one knows what the hell to make of him. Sloane in particular is ''[[DudeNotFunny not amused]]''.
* CastingGag: Both Joel Gray and Ron Rifkin portrayed the Emcee in different versions of ''Theatre/{{Cabaret}}'' - Gray won an Academy Award for his portrayal in the 1972 film version while both Gray and Rifkin were given a Tony award for the 1966 and 1998 Broadway revivals, respectively. In short, if anyone other than Rifkin was to portray Sloane, it would've been Joel Gray. And he does...kind of, in a weird surreal sort of way.
%%* TheChessmaster

->'''Portrayed by:''' Angus Scrimm

->'''Affiliations:''' SD-6 / The Covenant

A senior operative at SD-6, [=McCullough=] was one of the few agents privy to the truth behind Sloane's operation. He was primarily in charge of psychological examination, mental interrogation, and lie detecting. [[SarcasmMode Everybody loves]] [[TheDreaded McCullough]].

In truth, he was something of a DirtyCoward playing both sides for his own survival. After he escaped Sloane's dissolution and destruction of the Alliance of Twelve, he allied himself with Elena Derevko and created "Arvin Clone" for her using his own brain scans of Sloane from his days at SD-6. When Sloane discovered he was behind the experiment, he hastily poisoned his own coffee and committed suicide.
* ActionSurvivor: Not exactly, but any time something bad was happening at SD-6, he was conveniently not around for it. It's no coincidence either.
