[[folder:Decima Technologies]]
[[folder:"Vigilance"]]
Introduced in Season 3, Vigilance is a mysterious organisation dedicated to fighting against those that have destroyed privacy including private businesses and the government through the strategic use of assassination and Cyberwarfare. They have recently made contact with Team Machine.

!!In General

* TheCracker: A high percentage of Vigilance's core group are skilled computer programmers. The organization uses a [[https://www.torproject.org/ Tor network]] to communicate.
* CommieNazis: Combines ideology and tactics from the Tea Party, the Occupy movement and Anonymous.
* ThemeNaming: Their operatives' cover names are taken from the names of people who participated in the American Revolution.
* [[WellIntentionedExtremist Well-Intentioned Extremists]]
* [[WesternTerrorist Western Terrorists]]: They're American, and they want a revolution.


!!"Peter Collier"
->Played by Leslie Odom Jr.
-->''"We at Vigilance respect your privacy, unlike the government."''

* FauxAffablyEvil: After taking the foster brother of a defector from Vigilance hostage, he politely explains to the man how he's going to murder them both, while preparing to ambush the prison transport his target is on.
* TheFundamentalist: When John successfully talks [[spoiler: a man who had been ruined by Wayne Kruger]] into putting his handgun down and has seemingly made [[spoiler: Kruger, one of the most reprehensible POI's in the shows history]] see the error of his ways, Collier pulls out his own weapon, shoots [[spoiler: Reese and Kruger]] and then executes the POI. He's also not pleased that one of his hackers wasn't completely loyal to the direction he was taking Vigilance after the group committed it's first assassination. [[spoiler: He put quite a lot of resources in hunting the man down going, so far as to kidnap the man's foster brother for leverage and assemble a well armed hit squad to set up an ambush for the target.]]
* IHaveManyNames: Claims that "Collier" is but one of his names.
* KnightTemplar: In a big way. Initially Vigilance was merely planning to scare [[spoiler: Wayne Kruger]] into retirement but Collier convinced the majority of the group's leadership to go further [[spoiler: and approve of his proposal to assasinate the guy to teach "the first lesson".]] Later, after one of the hacker involved in that operation [[spoiler: turned traitor after getting a case of EvenEvilHasStandards and attempted to go to the CIA, Collier ruthlessly hunted him down, kidnapped his foster brother and calmly explained to the man exactly how he was going to murder them both as he and a Vigilance hit squad prepared to ambush the CIA prisoner transport.]]
* ManipulativeBastard
* TheMole: [[spoiler:He was this to the Kruger, watching him and getting close as a business associate.]]
* ScaryBlackMan: When he drops the charming businessman act he's all this,[[spoiler: coolly calling out Wayne Kruger on his perceived crimes before shooting him dead]]
* WeaponOfChoice: A Ruger SR9C
* WickedCultured: Has a deep appreciation for and is inspired by the American Revolution
--> '''Collier:''' Energy and persistence conquer all things -- Benjamin Franklin. ''

!!Alistair Wesley
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/wesley_alistair_2955.jpg]]
[[caption-width-right:350:''"This isn't your game and no one's invited you to play."'']]
->'''Played By:''' Julian Sands

* AffablyEvil: Very friendly with Reese. Slides into FauxAffablyEvil with virtually anyone else, however.
* BadAssCrew: His ex-SAS operators. However, John still manages to wipe the floor with them
* BlondeGuysAreEvil
* TheChessmaster: Even Reese admits his plan is remarkably well-put. See CrazyPrepared below.
* CrazyPrepared: in "Critical," he has a sniper in place to shoot a doctor's wife to blackmail the doctor into killing a patient. He has a backup plan to kill the wife in case his sniper is incapacitated, and then has a backup plan in case the first backup fails. Then we find out that this was just plan A and he also has a plan B already in place.
* GracefulLoser: Called Reese to congratulate him with foiling his plans.
* EvenEvilHasStandards: He won't break the rules he makes when he sets up his 'games.'
* EvilBrit: "Smashing."
* EvilCounterpart: A [[SharpDressedMan well-dressed]], cultured, polite, former member of a major intelligence organization who now works as a rogue agent on the criminal world. Both Wesley and Reese fit that description, the key difference is the side each other is on. And of Finch, both prefer to coordinate their operatives from a safe distance and are skilled strategists.
* ManipulativeBastard: Was manipulating the [=POI=] in "Critical" into being the perpetrator.
* ManOfWealthAndTaste: Not as rich as most examples, but he definitely qualifies (notice the size of his squad and how he dresses).
* NobleDemon
* NonActionBigBad: Implied from his dialogue in his final conversation with John when he talks about the time they met. Unlike John who is more hands on and likes to take part in the action, Wesley is trained to conceal himself and plan and coordinate operations from a safe distance.
* [[PrivateMilitaryContractors Private Military Contractor]]
* PsychopathicManChild: Sees his operations as "Games" with rules. As a result Finch uses this to pick apart his operation by invoking LoopHoleAbuse to buy time for the POI and her lover when he hacks the blood bank computer in the hospital to delay the surgery.
* RetiredBadass: Former MI6.
* SharpDressedMan
* SmugSnake: "Don't test me. I was expecting everything."
* WickedCultured
* WorthyOpponent: Sees Reese as one.

->'''Played By:''' Natalie Zea\\
'''Appeared in:''' "[[Recap/PersonOfInterestS01E01 Pilot]]"

An Assistant District Attorney whose Social Security number was the first given to the recently formed partnership of Reese and Finch. She's initially believed to be in danger of being killed [[spoiler: when in fact, she's actively assisting in framing innocent people for crimes committed by HR]]

* AmoralAttorney: On retainer for HR and is even more so than usual for this trope. She knowingly prosecutes innocent people framed by HR for the crimes they committed.
* BitchInSheepsClothing: Due to her pretty face and charming demeanor, she was quickly mistaken for (and assumed to be) a victim instead of a perpetrator. Comes to bite John hard after he's caught off guard with Fusco getting the drop on him.
* BlondesAreEvil: Yes she is.
* CaughtOnTape: Part of her EngineeredPublicConfession.
* EngineeredPublicConfession: How Reese and Finch take her down.

->'''Played By:''' James Carpinello\\
'''Appeared in:''' "[[Recap/PersonOfInterestS01E03 Mission Creep]]"

!!Megan Tillman
->'''Played By:''' Linda Cardellini\\
'''Appeared in:''' "[[Recap/PersonOfInterestS01E04 Cura Te Ipsum]]"

A physician who spent her adult life stalking her sister's rapist to get revenge.

* ActorAllusion: This isn't the first time Linda Cardellini has played someone in the [[{{ER}} medical profession.]]
* CrazyPrepared: To commit the perfect murder of her sister's rapist. Reese is extremely impressed in particular at the measures she's taken in preparing for her targets disposal once she's killed him.
* HospitalHottie: She's a doctor, and there's plenty of interest in her when she turns up to bars.
* NaughtyByNight: Averted, she plays this up to find her sister's rapist.
* SheWhoFightsMonsters: Reese warns her about the danger of this trope and convinces her to let him punish her target instead so she doesn't have to live with blood on her hands.

!!Samuel Gates
->'''Played By:''' David Costabile \\
'''Appeared in:''' "[[Recap/PersonOfInterestS01E05 Judgement]]"

* PapaWolf: When his son was taken, he was willing to go to extremes to save him.
* ReasonableAuthorityFigure: As a man of the Law, he is a tough but reasonable judge. He acknowledged Reese did a morally good action but not the legally right one, as Reese broke plenty of laws. Reese claims to Finch the Judge also implied he would assist them at some later date as a reward for getting his son back.

!!Ulrich Kohl
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/kohl_ulrich_5669.jpg]]

->'''Played By:''' Alan Dale\\
'''Appeared in:''' "[[Recap/PersonOfInterestS01E08 Foe]]"

A former East German Stasi spy who was betrayed by members of his unit, and planned to eliminate his former colleagues.

* {{Badass}}
** BadassGrandpa: Despite being well into his old age, he runs rings around the young German intelligence officer sent to take him down and has the honor of being the first person seen in the show who can go head-to-head with Reese, stay one step ahead of him and even incapacitate him with a well performed nerve strike.
* TheChessmaster: Has had a while to draw up a plan to track down and get rid of his former colleagues while in jail and executes it in a very efficient, methodical manner.
* ColdBloodedTorture: His preferred form is acupuncture needles to major nerves. Very clean and intensely painful.
-->They laughed at me when I learned to use these needles. They didn't laugh long.
* CoolGuns[=/=]RareGuns: His WeaponOfChoice is a [[http://en.wikipedia.org/wiki/Welrod Welrod]], a UsefulNotes/WorldWarII-era bolt-action pistol with an integrated suppressor that renders it extremely quiet (by gun standards).
* DrivenToSuicide: After he's informed that his wife is alive and meets with her, she informs him she's completely terrified by him and as he's got nothing else to live for, purposely makes Reese kill him by levelling his empty gun at his wife.
* EvenEvilHasLovedOnes: The whole reason why he's back in New York, to take revenge for himself and his wife. And when his wife reveals she's utterly terrified by him, he decides to make Reese kill him as he's got nothing left to live for.
* EvilCounterpart: To Reese .
* FriendlyEnemy: He is very friendly to John. They bond over discussing tradecraft and costs of being a professional killer while Kohl is taking breaks between torturing Reese. He's also highly regretful when he has to depart while at the same time is preparing to plug John in the head. Later after their final confrontation, they have a rather touching yet bitter-sweet conversation as Ulrich bleeds out on a park bench.
* NotSoDifferent: From Reese.
* RoaringRampageOfRevenge: Against his former comrades in the Stasi, for collectively betraying him after having {{Heel Realization}}s.
* SuicideByCop: Variation. He makes like he's going to shoot somebody and Reese fatally shoots him, then it turns out the gun was empty.
* TragicVillain: Began to scare those around him due to his fanatical and bloody kill count, so they betrayed him when they defected. He wasn't pleased and flew to New York to get even--but then he meets the wife he thought was dead, and his daughter who he never met and then after realising what he's become when his wife tells him she's utterly terrified by him gets Reese to shoot him, killing him.

* TraumaCongaLine: All she and her friends wanted after taking half a million dollars in laundered money was to take a modest finders fee and return it to the owners. The owner of the money hires a pair of professional killers to hunt them down, blowing one of her friends to smithereens and nearly ambushing her and Paula in their house. Later, Paula gets kidnapped and they nearly die in a hostage exchange gone wrong. Thanks to John's efforts, they live and even get to keep the money.

* ClearTheirName: She is seeking to prove her clients are really innocent of their crimes.
* CrusadingLawyer: Her primary goal is to help her clients.
* DefiantToTheEnd: Isn't begging when one of her colleagues (who's masterminded a scam which involves taking parolee's children into the foster care system for profit) is trying to kill her. She's rather angry in fact.
%%* HelloAttorney
* MarriedToTheJob: Her clients are number 1, 2, and 3 on her priorities.
* WideEyedIdealist: Even the man who tried to executes her points it out and in her superb ShutUpHannibal to his self serving justifications about why he's going to kill her, she "would rather bleed than not have a heart".

* [[{{Badass}} Badass Banker]]: With Finch's funding he's able to outflank the group that's trying to illegally short a certain gas company and ruin them. He also ruined Carl Elias' plans; Elias had expected to gain $300 million but only got $4 million for his war chest before the operation was blown by Team Machine.
* DarkAndTroubledPast: Abandoned by his father.
* ForensicAccounting
* HonestCorporateExecutive: Is genuinely trying to do the right thing, and while he gambles of a sort on the stock market, it's all calculated risk, and when a company his uncle invested in is shorted, he does his best (with a good deal of help from Finch) to restore the stock price.

Whoever he is, he saves a lot of lives...and he shoots a lot of kneecaps.”''

* BreakTheHaughty: Published a story without fully confirming the facts because she wanted the big scoop. She ended up unintentionally getting a crucial (and innocent) FBI informant killed. Agent Donnelly revealed crucial details of their investigation just to show her how badly she screwed up. Her reputation and career were devastated, with her past stories now in doubt. She managed to pick herself up with the help of John, and located the ledger that the informant planned to give to the FBI.
* GoingForTheBigScoop: Her main drive ad biggest character flaw.
* IntrepidReporter
* NiceJobBreakingItHero: Launched a story claiming that a man was being suspected of being HR's boss. Turned out he was actually an FBI informant who had the ledger that could point the direction to HR's boss, but had a bullseye painted on him with that story and got him killed.

* ForgivenessRequiresDeath: That's what Caleb thought, anyway, deciding to leave the proceeds of his future compression algorithm in a trust for his alcoholic mother. Finch vehemently disagrees.
* TalkingDownTheSuicidal: Finch does this alluding to the events which forced him to fake his death and lose his Fiancée and OnlyFriend, resulting in a HappilyFailedSuicide.
* TeenGenius: He's very smart, and developed a new compression algorithm. He's not quite on Finch's level... but he's very close and Finch sees a younger version of himself in Caleb.

* BadAssInDistress: Some Force Recon Marines attempt to kidnap him, beating him up, knocking him out and tossing him in the boot of a car. [[spoiler: Luckily, John's driving.]]
* DareToBeBadAss: His commanding officer believes he'd make a great SEAL if he tried out for his BUD/S.
* {{Expy}}: He's basically a younger Reese in a different service branch who hasn't made career decisions like joining the CIA or suffered personal tragedy in his life. Even Reese sees the similarities between him and Jack, giving him some friendly advice and also warning him not to accept any job offers from the CIA if he decides to become a SEAL.

[[spoiler: Collier is not impressed however and shoots him]]
* NeverMyFault: His main flaw, he never accepts responsibility for how his website helped destroy so many lives.

[[/folder]]

[[folder:Northern Lights]]
Northern Lights is the codename for an organization/program within the United States Government that controls the Machine, distributes its intelligence and takes action to keep its activities secret from the rest of the world. Northern Lights receives Numbers from an entity codenamed "Research" (actually the Machine's relevant list), and pulls its personnel from various government agencies, including the NSA, the CIA and the [[http://en.wikipedia.org/wiki/Intelligence_Support_Activity Intelligence Support Activity]].

!!In General

* CovertGroupWithMundaneFront: The late Special Counsel who oversaw their field operations masqueraded as the head of the RealLife Office Of Special Counsel, the people who conduct their field work are officially from the CIA and ISA and their entity known as "Research" belongs to the NSA.
* GovernmentAgencyOfFiction: They're a secret counter-terrorist organisation who uses The Machine's relevant list to hunt down threats to America's national security and stop them before they even occur.
* TheMenInBlack: They don't officially exist and are dedicated in keeping it that way.
* KillEmAll: Standard operating procedure in the event the existence of the Machine is compromised to the outside world. They're also willing to let terrorists attacks occur if necessary, if it means the source of the leak stands a good chance of dying in one.
* ProfessionalKiller: Their true strength. They have a small army of them to conduct counter-terrorist operations worldwide. They're also at Reese's calibre (like the ISA hit-squad in "No Good Deed" and Samantha Shaw). And if they find anyone who shouldn't know about the machine has learnt of its existence, they will be re-tasked in making sure that person does not live to tell anyone else.
* PunchClockVillain: The majority of their hit-squads have no knowledge of the Machine and are simply following orders.
* WellIntentionedExtremist: Their stated mission is to hunt down threats to America's national security and terminate them with extreme prejudice in order to prevent massive loss of life. However, they're paranoid about the American public finding out the existence of the machine and are all too happy to re-task their multiple hit squads to kill anyone, including innocent civilians, in order to keep it's existence secure.
* YouHaveOutlivedYourUsefulness: Does this to any employees who wish to leave the program and performed this to many of the personnel who built the machine.

* FamousLastWords: See FaceDeathWithDignity above.
* KillEmAll: To anyone who even suspects the Machine exists.
* TheManBehindTheMan: With respect to Weeks and Hersh.
* MoleInCharge: Has his day job in an agency that protects whistleblowers. As Henry Peck found out, he's not going to do his job if you try to expose the Machine.
* MissionControl: Fulfils this role for the project in the event the existence of the machine is compromised.
* TheNeedsOfTheMany: What he believes justifies his actions. See the quote above.
* [[NonActionBigBad Non Action]] [[TheManBehindTheMan Man Behind The Man]]: He has yet to pick up a gun or even get into a physical fight. That said, he isn't adverse to tense situations and remains ice cool.
* NoNameGiven: His name has yet to be spoken on screen. He was credited as "Pennsylvania Two" in the press release for "No Good Deed," but the press releases for all episodes since have credited him as "Special Counsel".
* NotSoDifferent: Invokes this when meeting Shaw. She agrees entirely.
** YouAreNumberSix: Given no real name given.
* PragmaticVillainy: Doesn't mind when Shaw blows Wilson away as she's called him out on the latter's stupidity in rashly taking a ContractOnTheHitman and given him the compromising evidence he was looking for. He lets her walk out....and makes sure Hersh intercepts her.

* TheDragon: With respect to "Pennsylvania Two".
* EvenEvilHasLovedOnes: He has a lover, which is how Root gets to him.
* DeathBySecretIdentity: He soon dies after finding out Finch is the one who actually built The Machine.
* {{Jerkass}}: Harold helps saves him but the guy turns on him and plans to bring him back to Northern Lights.

* BoomHeadshot: At the hands of Root.
* DeathBySecretIdentity: Finds out Finch built The Machine, and, well, see above trope.
* DroppedABridgeOnHer: Was played up as a potential threat in the final two episodes of season 1 - she was shown stalking Finch, discovering the Library, and finally confronted him with the intent of making him shut down the Machine - but ended up being killed off by Root practically mid-sentence.]]
* HeelFaceTurn: At some point, she turned against Nothern Lights and its methods and wanted to find a way to shut down The Machine.
* ProperlyParanoid: She knows The Machine is watching her, knows at least some of the ways it might be performing that monitoring--she moved to the National Radio Quiet Zone to avoid monitoring by wireless methods--she may be aware that it can act to protect itself should it figure out that she wants to shut it down, and she ''definitely'' knows just how ruthless Denton Weeks and the people behind him are.

* AssassinOutClassin: Gets subjected to this by Reese to a minor extent. Later suffers a more severe experience when going up against Root.
* AuthorityEqualsAsskicking: Since Special Counsel's death, he's been more or less in charge of the operations, now answering directly to Control.
* {{Badass}}: Since he's Reese's EvilCounterpart.
* CombatPragmatist: Just like Reese.
** BadassInANiceSuit: Nearly always wearing a nice suit.

** DragonAscendant: [[BiggerBad Control]] orders him to kill Pennsylvania Two, and he does so. He doesn't count as TheStarscream because he was JustFollowingOrders.
* EvilCounterpart: Reese describes him as "a lot like me."
** Hersh {{lampshades}} in "Booked Solid" that he and Reese [[NotSoDifferent aren't so different]].
* EvilMentor: For Shaw. As a result, she's just as good as John during combat situations. However, he may have taught her everything he knows but is perfectly willing to poison her when she resigns from the ISA.
** On the other hand in Season 3 during [[spoiler: 4C, he has a surprisingly amicable conversation with her while drugged and even asks in a concerned tone if Team Machine is treating her well.]]
* TheDeterminator: Rain or shine, he ''will' finish his mission.
* TheFixer: If there is a problem in Northern Lights that the other "official" hit-squads need not know about, he will be the one to clean it up. It also seems to extend to eliminating those that decide to leave the program including his protégée Shaw.
* GetIntoJailFree: His plan to infiltrate Rikers: pull a gun in a crowded street and start shooting in the air.
* ImplacableMan: Like the Terminator, even if he's grievously wounded, it will barely slow them down.
* KillEmAll: His general orders to anyone who might know about the Machine.
* LastNameBasis: Nobody ever refers to him by his given name. His full name wasn't even revealed until "Lethe", a good season and a half after his first appearance, when it appears in one of the Machine's calculation tables.
* MadeOfIron: And how! The man has been subjected to kitchen knives, gunshots and hand grenades, shrugging most of it off.
* MysteriousMiddleInitial: His full name was revealed as Robert N. Hersh. We don't know what the "N" stands for.
* ProfessionalKiller: As the fixer, he will handle situations, usually leaving behind a body or two.
* TheStoic: He keeps a calm face in most situations. Even when [[spoiler:Reese beat him and left him with a potentially fatal stab wound, the man didn't show much pain or anger, and later he's calm as a button about murdering his protégé ("Relevance") and his immediate supervisor and multiple co-workers ("God Mode")]]. Drops this when Root shoots him in ("Lady Killer"), he's left gasping on the floor bleeding out and is visibly in pain. In "4C" he's concerned about whether Shaw is doing fine in her new workplace.
* TortureTechnician: Shown as this in "God Mode". Control later implies he is rather skilled at it.

* TheCracker: During "Trojan Horse", they shut out Harold from the Rylatech servers by taking control of his laptop, overheating its battery and cause it to explode. So far, this is the only demonstration of their hacking abilities.

* HiddenAgendaVillain
* TheManBehindTheMan: With regards to Kara. But apparently, there's an even bigger fish behind Greer.
* ManOfWealthAndTaste: If his suits are any indication.
* NervesOfSteel: Maintains his composure even when Reese and Shaw are killing his minions and pointing guns at him.
* NobleDemon: Kept his end of the bargain with Stanton.
** He also kept his bargain with another one of his assets; commit suicide and take Decima Tech's secrets to the grave, and his family would be taken care of.
* NoNameGiven: On screen anyway. The press release for "Dead Reckoning" credits him as "Greer".
** OnlyOneName
* PragmaticVillainy: Seems to be his modus operandi; he's ruthless but never needlessly cruel, and seems to follow the line that the carrot rather than the stick is the better way to get your underlings to be loyal and willing to do anything.
* SharpDressedMan
* TheSpook
* TheSpymaster: The ultimate example in the show. ''He knows Reese and Shaw.'' And he knows of Finch.
* StiffUpperLip: Nonchalantly continued to look at a bit of paperwork while Reese and Shaw blasted through some of his mooks without even turning around to look, then leisurely finished looking at the paper and turned his attention to Reese and Shaw without so much as batting an eyelid or showing a flicker of discomfort at the situation that was apparently not in his favor. The fact that reinforcements were on the way probably contributed to this.

Reese's former CIA partner who was widely believed to be dead, but is later recruited by Decima Technologies.

* {{Badass}}: Gets Reese and Snow to be her puppets by attaching bombs to their chests.
* ColdSniper
* EvilMentor: For John, when they first meet, he's the NewMeat while she's the senior agent who's supervising him and after critiquing his insistence on not drinking wine (he's no longer a soldier and not drinking would probably blow his cover in a operational setting), she teaches him his first lesson by executing two traitors without warning and ordering John to clean up.
* FauxAffablyEvil: Very friendly and courteous towards Snow (and John Reese) while explicitly informing him he's a disposable asset.
* HiddenAgendaVillain: Whatever she's doing in season 2 that’s worth killing random civilians. It's eventually revealed that she was working for another covert organization which was seeking control of The Machine.
* ItsPersonal: She isn't happy that her superiors tried to have her eliminated.
* KarmicDeath: Snow kills her using the bomb vest she uses as his ExplosiveLeash.
** LaserGuidedKarma: Killed by the same explosive leash she was using to force Snow to work for her.
** [[HoistByHisOwnPetard Hoist by Her Own Petard]]]]
* JadeColoredGlasses: Utterly cynical, she lives only for her job, enjoys it and it rubs off on John during their time together.
* JerkAss: Rather abrasive to John when they first meet, him being the NewMeat who has much to learn while she is the more experienced agent who's wearing some heavy JadeColouredGlasses.
* KickTheDog: Has her moments but a major one is when she locks John, Mark and a innocent scientist in a DOD facility control room after activating the bomb vests.
* KillEmAll: Her solution to everything.
* NeverFoundTheBody: Admittedly, it does look like she was blown up so there wouldn't be a body, but that it didn't work out too well last time.
* NoOneCouldSurviveThat: The first time she escaped death, it was somewhat believable since she was covered by building structure. But seeing as how she was sitting right next to Snow with less than 10 seconds from detonation, and the sheer magnitude of the explosion, it's very hard to believe that she survived.
* ProfessionalKiller
** PsychoForHire: Snow considers her one. Rightfully so, it would seem.
* SemperFi: She's a former Marine and has a playful InterServiceRivalry exchange with John who's former Army Special Forces.
* [[HeWhoFightsMonsters She Who Fights Monsters]]: Like Reese, very aware of what it has done to her but doesn't mind in the slightest. "We're not... walking in the dark. We ''are'' the dark."
* [[HeKnowsTooMuch They Might Know Too Much]]: The suggested reason for why she and John were set up to be killed.
** Subverted in "Dead Reckoning" when Mark Snow reveals that his reasoning for setting them up to kill each other was because they were "damaged goods" and it was "poetic." It does nothing to help endear him to Stanton.
*** Not necessarily true. He was just noting the fact that it was poetic. But the fact that they knew too much likely was the main reason.
* WeaponOfChoice: suppressed Sig Sauer P239 which she uses to ambush Snow, kill Evans and later execute Donnelly.
* WomanInBlack
* YouHaveOutlivedYourUsefulness: Subjects John and Mark to this. It doesn't stick and leads to her undoing.

Introduced in Season 3, Vigilance is a mysterious organisation dedicated to fighting against those that have destroyed privacy including private businesses and the government through the strategic use of assassination and Cyberwarfare. They have recently made contact with Team Machine.

!!In General

* TheCracker: A high percentage of Vigilance's core group are skilled computer programmers. The organization uses a [[https://www.torproject.org/ Tor network]] to communicate.
* CommieNazis: Combines ideology and tactics from the Tea Party, the Occupy movement and Anonymous.
* ThemeNaming: Their operatives' cover names are taken from the names of people who participated in the American Revolution.
* [[WellIntentionedExtremist Well-Intentioned Extremists]]
* [[WesternTerrorist Western Terrorists]]: They're American, and they want a revolution.

-->''"We at Vigilance respect your privacy, unlike the government."''

* FauxAffablyEvil: After taking the foster brother of a defector from Vigilance hostage, he politely explains to the man how he's going to murder them both, while preparing to ambush the prison transport his target is on.
* TheFundamentalist: When John successfully talks [[spoiler: a man who had been ruined by Wayne Kruger]] into putting his handgun down and has seemingly made [[spoiler: Kruger, one of the most reprehensible POI's in the shows history]] see the error of his ways, Collier pulls out his own weapon, shoots [[spoiler: Reese and Kruger]] and then executes the POI. He's also not pleased that one of his hackers wasn't completely loyal to the direction he was taking Vigilance after the group committed it's first assassination. [[spoiler: He put quite a lot of resources in hunting the man down going, so far as to kidnap the man's foster brother for leverage and assemble a well armed hit squad to set up an ambush for the target.]]
* IHaveManyNames: Claims that "Collier" is but one of his names.
* KnightTemplar: In a big way. Initially Vigilance was merely planning to scare [[spoiler: Wayne Kruger]] into retirement but Collier convinced the majority of the group's leadership to go further [[spoiler: and approve of his proposal to assasinate the guy to teach "the first lesson".]] Later, after one of the hacker involved in that operation [[spoiler: turned traitor after getting a case of EvenEvilHasStandards and attempted to go to the CIA, Collier ruthlessly hunted him down, kidnapped his foster brother and calmly explained to the man exactly how he was going to murder them both as he and a Vigilance hit squad prepared to ambush the CIA prisoner transport.]]
* ManipulativeBastard
* TheMole: [[spoiler:He was this to the Kruger, watching him and getting close as a business associate.]]
* ScaryBlackMan: When he drops the charming businessman act he's all this,[[spoiler: coolly calling out Wayne Kruger on his perceived crimes before shooting him dead]]
* WeaponOfChoice: A Ruger SR9C
* WickedCultured: Has a deep appreciation for and is inspired by the American Revolution
--> '''Collier:''' Energy and persistence conquer all things -- Benjamin Franklin. ''

!!Alistair Wesley
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/wesley_alistair_2955.jpg]]
[[caption-width-right:350:''"This isn't your game and no one's invited you to play."'']]
->'''Played By:''' Julian Sands

* AffablyEvil: Very friendly with Reese. Slides into FauxAffablyEvil with virtually anyone else, however.
* BadAssCrew: His ex-SAS operators. However, John still manages to wipe the floor with them
* BlondeGuysAreEvil
* TheChessmaster: Even Reese admits his plan is remarkably well-put. See CrazyPrepared below.
* CrazyPrepared: in "Critical," he has a sniper in place to shoot a doctor's wife to blackmail the doctor into killing a patient. He has a backup plan to kill the wife in case his sniper is incapacitated, and then has a backup plan in case the first backup fails. Then we find out that this was just plan A and he also has a plan B already in place.
* GracefulLoser: Called Reese to congratulate him with foiling his plans.
* EvenEvilHasStandards: He won't break the rules he makes when he sets up his 'games.'
* EvilBrit: "Smashing."
* EvilCounterpart: A [[SharpDressedMan well-dressed]], cultured, polite, former member of a major intelligence organization who now works as a rogue agent on the criminal world. Both Wesley and Reese fit that description, the key difference is the side each other is on. And of Finch, both prefer to coordinate their operatives from a safe distance and are skilled strategists.
* ManipulativeBastard: Was manipulating the [=POI=] in "Critical" into being the perpetrator.
* ManOfWealthAndTaste: Not as rich as most examples, but he definitely qualifies (notice the size of his squad and how he dresses).
* NobleDemon
* NonActionBigBad: Implied from his dialogue in his final conversation with John when he talks about the time they met. Unlike John who is more hands on and likes to take part in the action, Wesley is trained to conceal himself and plan and coordinate operations from a safe distance.
* [[PrivateMilitaryContractors Private Military Contractor]]
* PsychopathicManChild: Sees his operations as "Games" with rules. As a result Finch uses this to pick apart his operation by invoking LoopHoleAbuse to buy time for the POI and her lover when he hacks the blood bank computer in the hospital to delay the surgery.
* RetiredBadass: Former MI6.
* SharpDressedMan
* SmugSnake: "Don't test me. I was expecting everything."
* WickedCultured
* WorthyOpponent: Sees Reese as one.
