[[folder:The Current [=BAU=] Team]]

!! Aaron "Hotch" Hotchner (Thomas Gibson)
TheStoic [[TheLeader leader]] of the Behavioral Analysis Unit's lead team, a former prosecutor who transitioned to criminal profiling and eventually rose to his current position. Until J.J.'s marriage, he was the only member of the team with a stable home family life ([[spoiler: for the first few seasons, anyway]]).

* AbusiveParents: It's heavily implied that Hotch's father abused him, and that's why he grew up to catch serial killers.
* AloneWithThePsycho: His encounter with Foyet.
* AwesomeByAnalysis: So much that the trope should be renamed "Hotchalanche".
* BadassBeard: Only in "It Takes a Village". The fandom consensus seems to be that he should grow it back. Apparently others associated with the show liked it, too: a brief clip of the BadassBeard is shown in the Season 7 opening credits.
* BadassBookworm: Collected coins as a kid, grew up to be a prosecutor, then took an apparent [[TookALevelInBadass level in badass]] and joined SWAT and then the elite unit of the BAU at the Bureau.
* BadassInANiceSuit: Always wears a suit, with the jacket buttoned neatly and a plain white shirt.
* BerserkButton: Threatening his family is a good way to get yourself a one-way trip to the emergency room. [[spoiler:Or beaten to death.]]
* BigBrotherInstinct: In addition to being this with BAU members, he's this to his little brother.
* BreakTheCutie: Done to him by Foyet.
%%* ByTheBookCop
* CaptainSmoothAndSergeantRough: On the rare occasion when a situation requires both him and Rossi to throw their weight around, Hotch is Captain Smooth.
* TheChainsOfCommanding: Takes his position as head of his unit very seriously.
* ColdSniper: Used to be with SWAT, one of the best shots in the cast, and the BAU agent with the highest killcount.
* TheComicallySerious: Even when joking, he maintains a very serious demeanor.
* DarkAndTroubledPast: It's heavily implied that his father who died from lung cancer was abusive.
* DeadpanSnarker: It comes out of ''nowhere''.
-->"Did you join a boy band?"
* DeadPersonConversation: Has one with Haley and ''Foyet'' after he's seriously wounded, in a coma, and unsure if he wants to stay with Haley or Jack more. It seems they both want him to return to the living and move on with his life.
* DeathGlare: Look at the picture to the right. That's him on a good day.
* DespairEventHorizon: [[spoiler: Listening to Foyet psychologically torture his ex-wife and son, promising to kill them, hearing Haley shot over the phone, and finding her body in their old home. Hotch ''loses it'' and empties his gun into Foyet, then beats him to death with his own hands.]]
* FamilyVersusCareer: In season three, Haley makes him choose - her and Jack or the FBI. He chooses the FBI. In season five, [[spoiler: after Haley is killed]], he must choose between them again. FBI's still winning, though he does [[spoiler: work out an arrangement with his sister-in-law to help raise Jack]].
* FBIAgent: And a very good one.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Choleric
* GoKartingWithBowser: Apparently Haley and Foyet got along in the afterlife (or Hotch's unconscious mind) a lot better than one would expect.
* GoodIsNotSoft: He's a very nice and pleasant guy, off the job and sometimes when on, but he never hesitates to pull the trigger to stop someone. That said, he does try to reason with them when he can.
* TheGunslinger: Of the team members he demonstrates the highest degree of skill and familiarity with firearms, especially when it comes to marksmanship.
* HeroicSecondWind: [[spoiler: After Foyet murders his wife, ambushes him in his own house, beats him badly and then threatens to go after his son after he's killed him, [[UnstoppableRage Hotch makes sure he doesn't survive long after that.]]]]
* HeterosexualLifePartners / HoYay: Hotch and Rossi, who are the only two team members to regularly call each other by their first names and have been very close friends for over fifteen years. Rossi is also able to consistently get a smile from Hotch, and Hotch has been known to joke with and confide in Rossi, something he almost never does with the rest of the team. To top it all off, in "The Pact", Hotch actually calls Rossi sexy, if a bit indirectly:
--> '''Garcia''' ''(In reference to Rossi giving away his vacation days.)'' Altruism is sexy.
--> '''Hotch:''' Yes it is.
* HighSchoolSweetHearts: Hotch and Haley married right out of high school. Apparently, it was love at first sight and Hotch joined a production of ''Pirates of Penzance'' as the "worst Fourth Pirate ever" to impress her.
* InSeriesNickname: Frequently called "Hotch" by the others.
* ItsPersonal: Any and all violence against children (especially physical child abuse) and cases that leave children without a father, not to mention his obsession with catching the Reaper. After the Reaper and the events of "100", we can add [[spoiler: [=UnSubs=] torturing their victims over the phone, and [=UnSubs=] who use knives and sexual sadism against their victims]].
* LastNameBasis: Except for Haley and Rossi, everyone calls him "Hotch".
* TheLeader: Type II.
* TheMario: His skill set seems to be the most well-rounded of the team members; conversely, while he's a very skilled profiler, he never shows detailed expertise in any specific area, beyond skill with firearms and ability to tolerate the bureaucracy involved in leading an FBI team.
* MarriedToTheJob: It leads to his divorce.
* NiceJobBreakingItHero: In "Doubt", [[spoiler:he ends up getting the [=UnSub=]'s profile ''completely wrong'', directly leading to the deaths of three people. This very nearly destroys his career, and ''does'' destroy Gideon's.]]
* NotSoStoic: "Mayhem", "Outfoxed", and especially "100". In general, whenever it comes to his family.
* OnlyKnownByTheirNickname: Almost everyone calls him Hotch, with occasional exception of Rossi who is an old friend.
* PapaWolf: Do ''not'' mess with his team. It will end badly. Furthermore, let the fate of [[spoiler: George Foyet/The Reaper]] serve as a cautionary tale against attacking Hotchner's family.
* PerpetualFrowner: Rarely smiles at work.
* TheProfiler: Along with the rest of the team.
* ReasonableAuthorityFigure: Honestly cares about his team and tries to do right by them.
* SamaritanSyndrome: Hotch tends to think he can save everybody, and actually goes and tries.
** This is deconstructed in the series twice - first, in "Omnivore", when Rossi gives him a verbal smackdown ("That isn't your conscience talking, Aaron, it's your ego."); and second, in "Hopeless", when he, along with Rossi and Prentiss, leave the group of [=UnSubs=] to their intended SuicideByCop, knowing he can do nothing to stop local law enforcement from enacting revenge.
** The unsub of "Scared To Death" lampshades this.
* SecondLove: Has this with Beth in season 7.
%%* TheSouthpaw
* TheStoic: Usually. In Season 7, he's largely gotten over Haley's death and has started dating. He now appears more often in casual clothing, smiles and laughs more, and everyone (especially Rossi) is absolutely delighted to see this.
* TallDarkAndHandsome: As a result of being played by Thomas Gibson.
* TeamMom: Truly cares about the well-being of all his people.
* UsedToBeASweetKid: Given how many bad things have happened to him, its sometimes sad to see moments in early episodes when we see how happy his family made him.
* [[WhenSheSmiles When He Smiles]]: They are few and rare (and occur mainly around his young son), but when they appear, they are stunning.

!! David Rossi (Joe Mantegna)

One of the founding members of the [=BAU=], who became wealthy and somewhat famous writing books about his experiences in the early days of the unit. Came out of retirement to fill the spot left empty by Jason Gideon's departure early in Season 3, serving as the team's oldest and most experienced member, though he's noticeably more wry and ornery than Gideon was.

* AmicablyDivorced: Above and beyond this with first ex-wife Carolyn, implied to be this with his two other ex-wives as well.
%%* AgentScully
* BadassBeard: Even [[GrowingTheBeard grows one]]. In his first appearance, "About Face", he's clean-shaven and a total jerkass. In the next episode, "Identity", he seems to have taken Hotch's advice to heart along with growing his goatee.
%%* BadassGrandpa
* BreakTheHaughty: "Damaged" does a number on him in season three; "Epilogue" does a worse one in season seven. He wasn't so haughty anymore, but [[spoiler: "The Replicator"]] breaks him ''even more''.
* ButForMeItWasTuesday: Inverted, Rossi spent twenty years obsessing over a case where parents were murdered in front of their children, and expected everyone else to do the same. When he tries to follow up on it, he is genuinely shocked that an isolated cold case has no new information and no one working on it. By the time the series rolls around, even the surviving children tell him to just drop it because they want to get on with their lives.
* CaptainSmoothAndSergeantRough: On the rare occasion when a situation requires both him and Hotch to throw their weight around, Rossi is Sergeant Rough.
* TheCasanova: Largely in backstory. Apparently, Rossi is the reason behind the Bureau's "no-fraternization" policy.
* TheChessmaster: His hostage-negotiation in "Minimal Loss" and interrogations in "Masterpiece" and "Zoe's Reprise" teach us that you do not want to try and out-maneuver David Rossi.
* TheConsigliere: Mostly to Hotch, but as of S5, to Morgan as well.
* CoolOldGuy: Knows enough about VideoGame/GrandTheftAuto to identify characters from it, claims he's played video games, and explains Twitter to Reid.
** He's also seen playing video games with Ashley at the end of "Coda".
** Helps Hotch coach Jack's soccer team. It's really kind of adorable.
* DealWithTheDevil: In "Profiling 101" [[spoiler: Rossi makes a deal with the [=Unsub=]. The [=Unsub=] is off death row and he will give Rossi the name and location of the body of one of his victims every year on a certain day. But it has to be on a special day of the [=Unsub's=] choosing. He chooses Rossi's ''birthday''.]]
* DeadpanSnarker: Among many other examples, he explains Reid by saying "He was left in a basket on the steps of the FBI."
* DisappearedDad: He recently learned that he had an adult daughter that he was not aware of by his second wife who gave birth after their divorce. To really add to it, it turns out his daughter is married with a two year old son.
* FamedInStory: When Manilow's not in town.
* FBIAgent: And well-known author on the topic.
* FirstNameBasis: Hotch is the only one to regularly call him "Dave". Likewise, he's one of the three people who ever call Hotch "Aaron". Rossi also calls Strauss by her first name ("Erin"), usually to piss her off.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Leukine
* GuileHero: As one of the most experienced profilers on the team.
* HeroicBSOD: Suffers from one in "The Replicator" after the titular [=UnSub=] [[spoiler: kills Strauss]]. Of course, part of his breakdown (him [[spoiler: pointing a gun at Morgan]]) can be blamed on the fact that he'd been [[spoiler: drugged by a deadly combination of ecstasy and other stuff that exacerbated his distrust]].
* HeterosexualLifePartners / HoYay: Rossi and Hotch, who are the only two team members to regularly call each other by their first names and have been very close friends for over fifteen years. Rossi is also able to consistently get a smile from Hotch, and Hotch has been known to joke with and confide in Rossi, something he almost never does with the rest of the team. To top it all off, in "The Pact", Hotch actually calls Rossi sexy, if a bit indirectly:
--> '''Garcia''' ''(In reference to Rossi giving away his vacation days.)'' Altruism is sexy.
--> '''Hotch:''' Yes it is.
* HiddenDepths: You wouldn't expect it given his age, but Rossi seems to be the team member with the most in-depth knowledge of video games.
* HonoraryUncle: Jack calls Rossi "Uncle Dave" at least once.
* ItsPersonal: The Galen case ("Damaged"), the Butcher case ("Remembrances of the Past"), idol worship/emulation, especially directed toward him ("Limelight", "Zoe's Reprise"), and religion ("Demonology", "Public Enemy").
* {{Jerkass}}: [[WriterOnBoard Depending on the writer]]. Moreso in season three, but there have been episodes in season five where writers of various episodes have him lapsing back into his Jerkass-y ways.
* JerkassFacade: Rossi comes off as an egotistical bastard when he first shows up, baiting [=UnSubs=] and insulting a lot of people's intelligence. Turns out he's just kind of crap at this whole "team" thing, and he has good intentions and simply isn't the best at expressing them; once he realizes that these people have his back ("Damaged", most notably), he's a lot more open and caring toward them, until he finally grows into the role of TeamDad.
* JerkWithAHeartOfGold: This is probably a better description of him. Yes, he's a little arrogant and egotistical at first, and yes, he may come across as a jerkass, but he's definitely a good guy who is truly passionate about catching bad guys and helping people. A good example is in "Penelope", when he's kind of pushy and harsh when questioning Garcia...but only because he wants to catch the guy who shot her.
* LargeHam: Can pull it off when needed, usually in the course of distracting the press (as seen in "The Performer" and "Painless"). Also, when cooking.
* LyingToThePerp: Rossi's a master at this - see "Masterpiece" and "Reckoner" for particularly spectacular examples. "Reckoner" deconstructed this, as Rossi tells the somewhat SympatheticMurderer that he slept with his wife, multiple times, and [[spoiler: the unsub dies without learning that it was a lie, which just adds an extra tinge of tragedy to an already fairly brutal episode]].
* MarriedToTheJob: Rossi, in his own words, is "more married to this team than I have been to three wives." He also hates going on vacation.
* TheMcCoy: Usually playing this role to Reid's [[TheSpock Spock]] and Morgan or Hotch's [[TheKirk Kirk]].
* TheMentor: To Seaver.
* NewOldFlame: It takes until season 7, and it's in [[TearJerker heartbreaking]] circumstances, but we do meet the first ex-Mrs. Rossi, Carolyn.
* NonIdleRich: He could stay retired thanks to being a wealthy best selling author but he just loves the job. He's also used his wealth on one occasion ("Snake Eyes") to help solve a case.
* OutGambitted: Pulls this on Henry Grace fairly magnificently in "Masterpiece", and it's one of his major moments of awesome.
* PapaWolf: It takes a bit for him to warm up to the team, but by "Masterpiece", he'll ''destroy'' you if you touch his team.
* ParentalSubstitute: For Ashley Seaver. Ironically, Rossi [[spoiler: captured her real father, a notorious serial killer]].
* RealMenCook: Turns out to be an excellent cook, especially Italian food.
* ReasonableAuthorityFigure: Acts as the ''de facto'' leader when Hotch isn't around; especially when compared with [[TyrantTakesTheHelm Erin Strauss]].
* RetiredBadass: Before he returns to the Bureau. He's not so much retired anymore.
* ScrewTheRulesImDoingWhatsRight: He does this often. In "Hit", when the FBI Director orders Strauss to sacrifice the [=UnSubs=]' hostages in order to take them down, the team immediately protests. Strauss asks them if they plan on defying the Director. Rossi's response is simply "Yes."
* SemperFi: He served in the Marines in [[VietnamWar Vietnam]].
* TeamDad: By virtue of being the oldest and most experienced member of the team.
* TokenReligiousTeammate: Is Catholic, and is the most openly sympathetic and comfortable member of the team in dealing with religious matters.
* UnclePennyBags: A bit more sarcastic than most but he still fits. He's invited his co-workers to his house to drink expensive wine, used his wealth to help victims that he's involved with personally like buying and maintaining a house for some kids ("Damaged") and paying for a victim's funeral ("Zoe's Reprise").

!! Derek Morgan (Shemar Moore)

[[TheLancer The team's second-in-command]], Morgan is a former Chicago cop turned FBI agent. The most socially outgoing and athletically inclined member of the team, he maintains an ongoing mock-romantic banter with Garcia as well as a big brother relationship with the bookish, nerdy Dr. Reid. Originally specializing in obsessional crimes, his role on the team has evolved to more general duties such as acting as Devil's Advocate when spit-balling ideas, bonding with victims[=/=]witnesses, and kicking down many, many doors.

* BaldOfAwesome: Does anyone actually remember the last time Shemar Moore had hair? [[Film/DiaryOfAMadBlackWoman He looked pretty nice then, too.]]
* BaldBlackLeaderGuy: Briefly in Season Five.
* BerserkButton: Touch his "babygirl" Garcia, and you are going to wish for death. Also, does not deal well with sexual abuse cases--it's [[ItsPersonal kind of close to home]].
* BigBrotherInstinct: He will put your head on a pike if you DARE to touch a single hair of his surrogate little brother Spencer Reid. Or anyone else on the team, actually.
* CantActPervertedTowardALoveInterest: Averted and subverted with Garcia--she's not technically his "love interest" and he doesn't have a problem at all sexualizing her. She has ''no'' problem reciprocating.
* ClearTheirName:
** In "25 to Life", when a man Morgan profiled as a rehabilitated offender is suspected of murder.
** Morgan himself in "Profiler, Profiled", when he is suspected of a series of murders in his old neighborhood.
* CoolShades: When it's sunny outside, Morgan is always wearing them.
* DarkAndTroubledPast: Watch "Profiler, Profiled" and all of Morgan's issues with authority figures and sexual abuse make sense. Then take a look at "Big Sea" and "The Company" and get a look into how fractured the stalking and disappearance of his cousin Cindy caused the family to be.
* FairCop: Literally. Morgan used to be a cop before he joined the BAU.
* FBIAgent: His job.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Choleric
* {{Flanderization}}: In the first season--particularly the first half--Morgan dressed in suits and other professional attire and was known as an intellectual who just happened to be good at fighting. While his brain hasn't left him, his style of clothing (to a much more casual dress) and the pronouncement of his emotions suggest that the "fighter" part of his persona has shoved his brain to the back seat, though he goes back toward his previous characterization after being promoted to unit chief. See also WhatHappenedToTheMouse below for more.
* GeniusBruiser: The most physical of the team, but as highly intelligent as any of them.
* HandsomeLech: The playful, mostly-directed-toward-Garcia kind. He's mostly smooth with ladies he seriously wants to date, and turns on a more over the top 'lech' attitude with Garcia, older women and/or bums...and it's ADORABLE.
* HeterosexualLifePartners: With Reid. Although the fandom prefers to forget the "Heterosexual" part.
* HollywoodAtheist: He was a devout Christian who lost his faith after [[spoiler:being molested]] and became angry and resentful towards religion and God.
* ItsPersonal:
** Sexual abuse cases ("Profiler, Profiled"), racism ("Fear and Loathing", among others), and violence against cops ("Brothers in Arms").
** He's also had the Prince of Darkness ("Our Darkest Hour"/"The Longest Night"), the Reaper ("Omnivore", "Faceless, Nameless"), clearing the name of Don Sanderson ("25 to Life"), and his cousin's disappearance in "Big Sea" and "The Company".
** He spends almost every waking moment after Prentiss's "death" hunting down Ian Doyle, culminating in going off-grid.
* MixedAncestry: Like his actor, Morgan's dad is black, while his mother is visibly white.
* MrFanservice: Particularly apparent in "Snake Eyes," where he steps out of a shower dripping wet with a loving pan up his body.
* TheNicknamer: Can fall into this when talking to Reid ('Kid', 'Pretty Boy', 'Genius') or Garcia (too many to list). His favorite by far is "Babygirl".
* NoOneGetsLeftBehind: He does this for Prentiss in "Lauren".
* ParentalSubstitute: For Ellie Spicer.
* PlatonicLifePartners: With Garcia. No one messes with his "Baby Girl".
* RaisedByDudes: Inverted, with interesting consequences. All of the relatives we've ever met of his are female (his mother, his three sisters, his aunt, his cousin), which reinforces why Morgan treats the women in his life ([[PlatonicLifePartners especially Garcia]]) so well.
* RapeAsBackstory: Painfully revealed in "Profiler, Profiled".
* SmarterThanYouLook: [=UnSubs=] often assume he's just DumbMuscle. He's not.
* TokenMinority: The only person of color on the team.
* ToKnowHimIMustBecomeHim: Fun drinking game in the first couple seasons - count the number of times Morgan says "I'm the [=UnSub=]".
%%* UrbanLegendLoveLife
* WhatHappenedToTheMouse: Not Morgan himself, but his work specializing in obsessional crimes. The fact that he has this specialty hasn't come up in ages, even in episodes such as "The Big Wheel" where the crimes clearly are obsessional.
* WouldHitAGirl: Blows Lucy away without a second thought.
* WouldHurtAChild: If that child were a killer, or so he claims to a teenage unsub in "Safe Haven." Fortunately, the unsub ultimately surrenders voluntarily.
* YouCalledMeXItMustBeSerious: After being promoted to Unit Chief in Season Five:
-->'''Morgan''': Thanks, Babygi--Agent Garcia.

!! Spencer Reid (Matthew Gray Gubler)

The youngest member of the team, Reid is a child prodigy genius with an I.Q. of 187, an eidetic memory, and an encyclopedic knowledge of a wide variety of different fields. He also has underdeveloped social skills and various Vulcan-like character tics that stem from being a walking computer and serve as the source of a lot of the show's humor.

* {{Adorkable}}: In general, but especially with his giant NerdGlasses when he was a child.
* AspergersSyndrome: According to WordOfGod. The [=UnSub=] of "Broken Mirror" mentioned this as well.
* AwesomeByAnalysis: Does all the pattern analysis for the team.
* TheBabyOfTheBunch: Reid is the youngest member of the main characters.
* BadassAdorable: He's a fully trained FBI agent, but acts like an overgrown puppy at times.
* BadassBookworm: If the BoomHeadshot in "L.D.S.K." didn't convince you, his thirteen-minute-long profile from thin air to keep from being killed by Chester Hardwicke in "Damaged" might. When Hotch compliments him on the headshot in "L.D.S.K." however, Reid blushes and jokes he was actually aiming for the unsub's knee.[[note]]The unsub is wearing body armor, and it's made clear than if he's not killed immediately, he ''will'' take someone with him. It's also clear that given the setup, he was actually aiming for the head.[[/note]]
* BadDreams: Nightmares have been plaguing him since childhood.
* BerserkButton:
** Don't tell him that bullying is something some kids ''have'' to deal with. If looks could kill...
** Don't abuse or insult the mentally-ill around the kid whose mother is a diagnosed schizophrenic.
* BewareTheNiceOnes: He can shoot straight ''sometimes'', you know. PlayedForLaughs in "Painless".
--> "Never wage a practical joke war against an MIT graduate, because we have a history of going nuclear."
* BreakTheCutie: ''So'' many times. It seems the writers like to torture him, lock him up, drug him, [[spoiler: infect him with anthrax,]] tie him up...
** [[spoiler: Prentiss' supposed death]] could count as well. How did he spend the time while she was away? At JJ's house, crying, and almost relapsing on Dilaudid.
** He finally gets a girlfriend, a clever geneticist, but they only communicate via handwritten letters and payphones. When he finally sees her face-to-face, [[spoiler:she's being held at gunpoint by a jealous woman, then she's ''killed in front of him'' by said jealous woman in a single-bullet murder-suicide.]] Ouch, writers. ''Ouch.''
* CallingTheOldManOut:
** Reid does this to his own father in 4x7 "In Memoriam", and then to [[spoiler: the unsub's father in "The Uncanny Valley"]].
** Inverted in 4x20 "Conflicted", when he [[spoiler: interrupts Adam/Amanda Jackson's murderous version of this]].
* CannotTellAJoke: Spencer tells hilarious jokes ... if you're a genius speed-reading polymath with an eidetic memory. Otherwise, not so much. He seemed pretty surprised when the villain from "Masterpiece" actually understands a joke he told a university class.
* ChildProdigy: Graduated from high school at 12, had two [=BAs=] by 16, has an IQ of 187 and an eidetic memory.
* CluelessChickMagnet:
** Poor guy doesn't realize that when beautiful movie stars kiss him it's because he's a babe, not because of '[[FlorenceNightingaleEffect transference]]'.
--->'''Prentiss''' ''(after interviewing the homeless for information)'': How'd you guys do?\\
'''Hotch''': Well, Reid got propositioned by every prostitute we talked to...
** Also this (after Morgan teases him about "not being able to get a date") [[note]]Of course, given that we've actually ''seen'' women throwing themselves at him, he probably just didn't notice. [[/note]]:
--->'''Reid:''' Do you think that [being interested in weird things] is why I can't get a date?\\
'''Elle:''' Have you ever asked a girl out?\\
'''Reid:''' No.\\
'''Elle:''' That's why you can't get a date.
* DarkAndTroubledPast: Poor kid. Mommy's schizophrenic and Dad abandoned everyone. At one point, he was going to be the next victim of a local pedophile and child murderer. Biggest brain in the room and usually the one targeted physically by the serial killers.
* DisappearedDad: First with his own father, and then with his ''father figure'', Gideon.
* DisturbingStatistic: He's a veritable fountain of these. If the team needs to know a statistic relating to crime, you can bet he'll know it.
* FanWank: In an in-universe example, Reid has a tendency to bore his colleagues with rants about the specs of the [[Franchise/StarWars Death Star]], that ''Film/BillAndTed'' was a ripoff of ''Series/DoctorWho'', and the nature and "surprising infrequency" of science errors in the original ''Series/{{Star Trek|The Original Series}}''.
* FBIAgent: Though he goes by "Doctor" and not "Agent."
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Phlegmatic
* {{Flanderization}}: We all know that athletics are not Reid's strong suit, but failing EVERYTHING involving physical exertion (marksmanship, physical training, the obstacle course, Hogan's Alley, etc) at the Academy? It's a little extreme and it begs the question of how he not only passed the Academy, but continues to pass his field qualifications.
* GeekPhysiques: The skinny kind. Probably as a result of ForgetsToEat.
* GeniusSweetTooth: If there's junk food around, Reid ''will'' find it.
* GoodCounterpart: He has the most EvilCounterpart's and even physically resembles some [=UnSubs=].
* GoodWithNumbers: And has been banned from many a casino as a result.
* HeterosexualLifePartners: Definitely shows signs of this with Morgan.
* HiddenDepths: Who'd have pegged ''Reid'' as a basketball coach in high school?!
* HollywoodNerd: He's played by a former model.
* ILetGwenStacyDie: [[spoiler:He blames himself for letting Maeve be killed by her stalker.]]
* [[ImTakingHerHomeWithMe I'm Taking Him Home With Me]]: He does tend to engender this type of response in some people.
* InSeriesNickname: "Spence" from JJ, "Kid" and "Pretty Boy" from Morgan, and countless ones from [[TheNicknamer Garcia]], 'Gorgeous Grey Matter' being a notable example. "Pipe cleaner with eyes" from a witness.
* InsistentTerminology: ''Doctor'', not ''Agent''.
* InsufferableGenius: Unlike most versions, this comes not from arrogance (because he's quite humble) but simply his habit of outshining others with his knowledge, making them look bad by comparison, and his MotorMouth tendencies.
-->'''Prentiss:''' ''(After he puts together a star puzzle)'' There's a lot to hate about you Dr. Reid.\\
'''Rossi:''' Play poker with him sometime.\\
'''Morgan:''' Try playing chess with him.\\
'''Garcia:''' Or Go.
* IntelligenceEqualsIsolation: Reid's school experience - "Being the smartest kid in class is like being the only kid in class."
* JamesBondage: Definitely. The most danger-prone agent out of the bunch. Enough said.
* TheLostLenore: [[spoiler: seems to see Maeve as this in in season 9.]]
* LovableNerd: Everyone seems to want to take care of him.
* MotorMouth: Talks ''extremely'' fast, about virtually any subject down the the most pedantic minutiae. A fun drinking game is to count how often Reid is interrupted by an irritated teammate.
* MustHaveCaffeine: Everyone in the BAU appears to like coffee, but Reid's is the only one to have a big point made of it. Probably because of all of the sugar he takes with it.
* NearDeathExperience: [[spoiler:Tells the team in "Epilogue" that when he was dying in Tobias Hankel's shed, he felt a warmth and saw white lights.]]
* NerdGlasses: Wears these from time to time.
* NerdsAreSexy: Lila Archer (1x18 "Somebody's Watching"), Austin (4x9 "52 Pickup"), and various prostitutes (c.f. 2x22 "Legacy" and 4x7 "In Memoriam") seem to think so.
* NiceGuy: He might have NoSocialSkills, but Reid compensates by having ample amounts of compassion.
* NoSocialSkills: He's VERY awkward around people other than the team.
-->'''Reid''': I was able to differentiate between two distinct voices, two authors. I found various idiosyncratic words, phrases, punctuation and orthography within the blog. Entries consistent with each separate person, words like soda and pop. One guy uses dashes while the other guy uses ellipses. ''(chuckles)''\\
'''Detective Linden''': ... where'd you find this kid?\\
'''Rossi''': He was left in a basket on the steps of the FBI.
* NotThatKindOfDoctor: Gideon always introduces him as "Dr. Reid" and Hotch does occasionally, leaving Reid to explain that he hasn't been to medical school, [[http://www.youtube.com/watch?v=1qMKGuel6OQ but does have three [=PhD=]s]]. Note that this doesn't stop him from trying to use his title of "Doctor" to approve himself for active duty in Season 5 when he disagreed with the notion of taking time off to let his leg fully heal.
* OlderThanTheyLook: Post 'boy band' haircut, he manages to look about 12, despite the actor being 29 at the time.
* OmnidisciplinaryScientist: Oh god. So much.
* PhotographicMemory: His eidetic memory has been proven to be imperfect - for example, his memories from his very young childhood are murky at best - but, generally, it's reliable.
* PrankDate: Was victim to this in high school. It was... brutal, to say the least. He was lured to the football field, where he was ambushed, stripped naked and tied to a goal post ''all night''.
* ThePrankster: Do ''not'' try and prank an MIT grad, Morgan. Giving Reid's number to a bunch of press leads to a hilarious return-serve of Reid hijacking all of Morgan's electronic equipment ([=iPod=], cell phone, etc) and programming them to play a looped message of him ''screaming''.
* PrecisionFStrike: Reid easily having the cleanest mouth of the team, when he does swear, it means something.
** Played for comedy in season 7.
--->'''Reid:''' Loner, invisible, boiling rage--''son of a bitch!''
** And played for drama in season 8.
--->[[spoiler:'''Reid:''' Maeve ''is'' somebody and this ''bitch'' is a nobody!]]
* PrettyBoy: Hoo boy. In the words of Shemar Moore (the actor who plays Morgan), 'Matthew's so pretty he's almost a girl.' It's also his [[InSeriesNickname nickname.]] Unsurprising, given that he's a real-life Calvin Klein model.
* PrimalFear: It's revealed in ''The Boogeyman'' that he's scared of the dark.
* PuppyDogEyes: It's his default expression.
* RevolversAreJustBetter: Switches from a pistol to a revolver as his sidearm in Season 4. This is especially notable when you remember that when Reid was kidnapped by Tobias Henkel, [[spoiler: he was forced to play Russian Roulette four times and survives, and later manages to get the same gun (still with only one bullet) away from him and kills him with one shot.]] It's quite possible he started carrying a revolver for this reason.
* SarcasmBlind: Not always, but part of him having NoSocialSkills means that he often gives sarcastic questions actual answers, hearing a request for information rather than an expression of exasperation. He's actually pretty good at using sarcasm, though.
* SesquipedalianLoquaciousness: He uses so many SAT words that it's not even funny.
* TheSmartGuy: Three [=PhD=]s, one of them in engineering, check. Difficulty with guns (at least, in "LDSK"), check. Prefers to talk people down rather than risk shoot-outs, check. BadassBookworm, check.
* SmartPeoplePlayChess: Inverted and subverted; Reid plays, but is constantly beaten by Gideon, and Prentiss out-thinks him in 2x10 "Lessons Learned." Additionally, in "The Uncanny Valley," it's implied that he stopped playing against people after Gideon left, while playing out every possible game with himself. [[spoiler: Until the end of the episode, anyway.]]
* SnarkKnight: Turns into this towards JJ after he finds out that [[spoiler: JJ lied to him about Prentiss' death.]]
* SomedayThisWillComeInHandy: Reid has so much apparently useless knowledge that it is, in fact, ridiculous. By contrast, his knowledge of pop culture varies: he knows Siouxsie and the Banshees but not ''Literature/{{Twilight}}'' or Music/LadyGaga.
** And some of it does come in handy, such as in "Plain Sight", where he recognizes the literature that the unsub writes quotes from at the crime scenes.
** Lampshaded by Morgan in "True Night":
--->'''Reid:''' You should have listened to me.\\
'''Morgan:''' It wouldn't have saved that much time, Reid, let it go.\\
'''Reid:''' The interchange between the 405 and the 101 freeways is consistently rated the worst interchange in the entire world.\\
'''Morgan:''' ''Why do you know that?''\\
'''Reid:''' The government report.\\
'''Morgan:''' So what?\\
'''Reid:''' So you work for the government, you don't read the reports?\\
'''Morgan:''' On traffic patterns in a city 2,500 miles from where I live?\\
'''Reid:''' 2,295 miles.\\
'''Morgan:''' ''Don't'' make me smack you in front of all these people.
* TheSpock: An interesting take on this trope. He's usually the most logical team member and the one to come up with the most effective plans, but he's still not even close to handling cases unemotionally.
* SuperSpeedReading: Has been shown reading and rapidly turning the pages.
* TeamPet: Everyone wants to take care of him.
* TeensAreMonsters: Holy ''shit'', his classmates in his {{Backstory}}. See PrankDate above, and keep in mind he would've been ''at most twelve''.
* TookALevelInBadass: A few over the course of the show, but a spectacular one in "It Takes a Village".
-->'''Interviewer''': Now, calm down, Agent--\\
'''Reid''': [[Awesome/CriminalMinds This is calm and it's]] ''[[Awesome/CriminalMinds Doctor]]''.
* TropaholicsAnonymous: In 3x16 "Elephant's Memory," he's seen attending a meeting of "Beltway Clean Cops" to cope with the Dilaudid addiction he developed in season two.
* WhatTheHellHero: He is ''not'' happy to learn that [[spoiler:the fact that Prentiss' death was [[FakingTheDead faked]] was intentionally hidden from him]]. He lets go of most of his anger after "Proof", but he still remains somewhat distant from the rest of the team, [[spoiler:JJ]] in particular.

!! Penelope Garcia (Kirsten Vangsness)

The team's MissionControl, Garcia is an extremely skilled hacker who was captured by the FBI and offered a job by Hotchner as an alternative to prison, due to her extreme skill and obvious strong sense of justice. In both style and personality she's the most free-spirited and non-traditional member of the team, due to her origins in hacker culture and her status as a techie rather than a field agent.

* {{Adorkable}}: She is enthusiastic and awkward in equal parts.
* AwesomeByAnalysis: She's a technical analyst, which means she sifts through electronic records and finds the good bits, and then puts them all together in a big picture. And remember, she learned at the feet of Aaron Hotchner.
* BadassBoast: In a slightly nerdy way whenever she answers the phone to the team, for example she's announced herself "the fountain of all knowledge" on one occasion. Also see the quote under BewareTheNiceOnes, she could absolutely do that. There's also her CMOA at the end of "The Internet Is Forever".
* BewareTheNiceOnes:
-->"Girlfriend? Kevin, if you come within 100 feet of Agent Rossi, I will unleash an unrecoverable virus onto your personal computer system that will reduce your electronic world into something between a Commodore 64, and a block of government cheese... call me later!"
* BreakTheCutie: Her [[spoiler: shooting]] in "Lucky"/"Penelope", and the subsequent episodes that show her healing process - "House on Fire" and "Exit Wounds".
* BunnyEarsLawyer: Does not look the part of an FBI employee at all, but it doesn't matter because she's brilliant at her job.
* CantActPervertedTowardALoveInterest: Averted and subverted with Morgan - he's not her love interest and she sexualizes him plenty.
* CharacterizationMarchesOn: She's nearly unrecognizable to what she would later become in the pilot, in which she's a DeadpanSnarker who dresses like a stereotypical "working stiff" and who actually easily gives up trying to hack something.
* ChronicHeroSyndrome: One of the sweetest and most justified versions. After spending her days catching murderers, she volunteers one day a week to counsel the families of murder victims.
* ControlFreak: She admits to being one.
* DarkAndTroubledPast: Both of her parents died in an automobile accident when she was only 18.
* DependingOnTheWriter: Whether or not she's an only child. S2 says she has four brothers. S6 says she doesn't.
** Mind you, she mentioned having a step-father and that she was 18 when her parents died, so both could be true at once if the brothers were older.
** It's funny how a character on a show about murders and such that a character can go from four brothers to none and instead of making a plot they just ignore it.
* DoesntLikeGuns: In "Penelope", Morgan tries to give her one for protection.
-->'''Garcia''': I don't believe in guns!\\
'''Morgan:''' ''(shoves one into her hands)'' Believe me, they are '''[[DialogueReversal very real]]'''!
* {{Expy}}: Garcia shares a lot of personality traits with [[Series/{{NCIS}} Abby Sciuto]], though their precise roles are different. Both shows are on CBS. Funnily enough, this is likely a complete coincidence; Garcia's character was originally going to be a chubby, middle-aged Latino man. Then they met Kirsten Vangsness.
* FakeGuestStar: In Season 1; they just didn't have the money to put her in the title credits. In fact, she is the ''only'' character to be [[PromotionToOpeningTitles Promoted To Opening Titles]] who was not a replacement for a departed character. She's credited with "Also Starring" from Episode 14.
* FeminineWomenCanCook: Subverted in "Proof". Garcia can bake, but apparently lacks most cooking skills. Rossi ends up teaching her.
* FieryRedHead: For one season.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Sanguine
* GeekyTurnOn: How she first meets Kevin.
* TheHeart: She and JJ tend to share this role between them.
* HeterosexualLifePartners: She, Prentiss, and JJ are all extremely close - Garcia is even godmother to JJ's son Henry.
* InSeriesNickname: So, so many from Morgan.
* MagicalComputer: Garcia can do things with computers that are flat out impossible and can deliver instant search results from {{Omniscient Database}}s that sometimes contain info that have absolutely no business being online. Months old surveillance footage, sealed court records, records that predate the digital age, etc. Nothing is off-limits or takes any real amount of time to sift through or cross-reference. On the other hand, this saves us from having to deal with months of subpoenas and dead end searches, so TropesAreNotBad. The show {{lampshades}} this with repeated references to how good she is in that "she can find anything". The Sheriff in "A Rite of Passage" evens says she wants someone like Garcia for Christmas.
%%* ManicPixieDreamGirl
* {{Meganekko}}: When she's wearing her glasses.
* MissionControl: Does all the BAU's computer work and rarely goes out in the field.
* MoralityPet: To Morgan, but mostly to the entire team as a whole.
* MulticoloredHair: With more colors than a cotton candy machine. Garcia digs the Manic Panic.
* MsFanservice: She's quite well-built, to say the least, and several of her outfits, particularly the dress she wore to [[spoiler:JJ's wedding]], seem designed to show it off. Rather blatant in "Snake Eyes," which almost literally opens with a ''very'' good look down her nightshirt. May or may not be a coincidence that the same episode had the series' most blatant bit of ''male'' fanservice, as well. Considering Garcia would be HollywoodPudgy on most shows, it's refreshing to see her being treated as one of the most attractive characters on the show.
* NearDeathExperience: In "Penelope", she tells Morgan, Emily, and Reid that she heard the David Bowie song "Heroes" while she was coding in the ambulance, which makes her wonder if David Bowie is God.
* TheNicknamer; You could count on one hand the number of time she refers to anyone she's talking to by their real name. Made all the more impressive in that she comes up with a new one ''every'' time. In fact, this is ''such'' an important character trait, that when Reid calls her after he's [[spoiler: been infected with anthrax,]] he can tell how upset she is by the fact that she calls him "Reid".
* [[NonActionGuy Non-Action Girl]]
* OhCrap: When she gets a call from Morgan she usually answers in a very flirty way, which leads to these moments when he replies "You're on speakerphone". The crowner has to be Garcia's expression in "In Name and Blood":
-->'''Garcia''': Talk dirty to me.\\
'''Strauss''': This is Section Chief Strauss.
** Interestingly enough, "The Internet Is Forever" implies she's not a fan of social networking sites.
** Goes to a major convention with Reid in "Hit/Run", dressed as the Eleventh Doctor from ''Series/DoctorWho''.
* PlatonicLifePartners: With Morgan, her "sweet prince" and other assorted nicknames.
* PlayfulHacker: One of the most dangerous in the world, actually.
* PromotionToOpeningTitles: From season 2 onwards.
* RecruitingTheCriminal: After she got caught hacking the FBI's database, the choice was pretty much "join the Bureau or we put you in jail". In "The Black Queen" it's implied that she let herself be caught to escape her controlling boyfriend.
* TheReliableOne: Always working away in her office, just a phone call away.
* RightBehindMe: How she meets Prentiss' replacement, complete with lampshading: "Oh god, I'm doing that thing where I'm talking and they're right [-behind-] [--me--]..."
* WhyDoYouKeepChangingJobs: Averted in that any time Garcia takes a role other than computer-related analysis, there's always a good reason and she goes back to technical analyst when it's finished (ex: doing some profiling during "House on Fire" at Hotch's request; becoming the interim media liaison [[spoiler: when JJ leaves]] because she wants to help out).

!! Jennifer "JJ" Jareau (A.J. Cook)

Originally the team's media liaison in charge of controlling the media response around investigated crimes (and thus its potential effect on the [=UnSub=] as well as the community), in the latest seasons she has transitioned to a more hands-on role as a full-time field agent[=/=]profiler.

* ActionMom: Don't try to go after her son. It will not end well for you.
* AlliterativeName: Applies with and without her nickname.
* AloneWithThePsycho: ''The Performer'' and [[spoiler: ''All That Remains'']].
* BewareTheNiceOnes: "Revelations" and kill-shots to three rabid dogs. "Penelope" and one beautiful [[BoomHeadshot headshot]] through a plate-glass window. "The Performer" and a shovel to the back of an [=UnSub=]'s head. In ''Nanny Dearest'' she [[BoomHeadshot pops the [=UnSub=] in the forehead]] from nearly [[ImprobableAimingSkills a block away with her sidearm]]. Do ''not'' fuck with JJ.
* TheBusCameBack: In "Lauren" for one episode, then as of "Out of the Night", JJ is officially back.
* CharacterDevelopment: JJ's original role on the team was to manipulate the media (and through them the bad guys) as well as deal with people the team came into contact with. Starting at the end of season five her role noticeably expanded until her temporary departure part way through Season 6. As of Season 7's "Proof" she's out pounding the pavement with Reid as well checking out body dumps and talking profiler-speak to the locals with Rossi. Part of this has to do with the fact that in Season 7, she has a different official job. The role of media liaison had already been filled when she returned to the team. The only way she could come back was to fill Prentiss' (then) vacated spot. (When Prentiss came back, she took Seaver's spot, and Seaver left). She's officially one of the profilers now. Hotch had suggested getting qualified for that role years before (back in something like Season 3), but she was happier as a media liaison at the time.
* DarkAndTroubledPast: Her sister killed herself when JJ was eleven by slitting her wrists.
* DeadpanSnarker: JJ seems to have absorbed best-bud Emily's penchant for sawdust-dry wit in season 7.
%%* FairCop
* FBIAgent: Like all the main cast.
* FirstNameBasis: She's the only person besides his mother who calls Reid "Spencer".
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Phlegmatic
* HappilyMarried: In Season 3's "Lo-Fi", Will [=LaMontagne=] tells the team that he's asked JJ to marry him. They are shown living together during Season 7, with Will taking care of Henry while JJ is chasing a serial killer in Tornado Alley, but not officially married until the season 7 finale.
* ItsPersonal: Small-town violence ("North Mammon", "Risky Business"), stalking ("The Crossing"), and suicide ("Risky Business").
* MamaBear: DO NOT threaten her kid when she's around, she WILL kick your ass, as a thrillseeking bank robber/terrorist found out in the season seven finale.
** And don't do anything to harm her team, either, that gun is not for show.
* PutOnABus: Thanks to ExecutiveMeddling, she left in Season 6's "J.J.", accompanied by loads of RealitySubtext.
* TookALevelInBadass: ''Four'' over the course of the show.
* WhatHappenedToTheMouse: Will and Henry seem to appear and disappear in continuity DependingOnTheWriter.

!!Kate Callahan (Jennifer Love-Hewitt)

An undercover member of the FBI's Sex Crimes Unit who joins the Behavioral Analysis Unit in Season 10 after Alex Blake's departure at the end of Season 9.

* MsFanservice: Wears a ''very'' low-cut shirt in her last scenes.
* ParentalSubstitute: After her sister and brother-in-law died in 9/11, Kate became the legal guardian to their (now 13-year-old) daughter Meg.
* RememberTheNewGuy: Apparently the team has already met her several times off-screen. They all comment how great she is.
* TomboyAndGirlyGirl: A bit more girly than the Bureau's previous brunettes: she tells Garcia about cute animal videos she's seen, which astonishes Garcia in that there could possibly be something cute on the internet she hasn't seen before due to her need for BrainBleach, and talks with JJ about what skin treatments are best to help heal injuries.
* UndercoverCopReveal: In the season premier, we saw her working as an undercover cop before joining the BAU.
* [[WhenYouComingHomeDad When You Coming Home, Mom?]]: At the end of the season premier, she apologizes to Meg for being away for two days. (We learn the details of their relationship later, but their FirstNameBasis indicates that Kate may not be Meg's mother.)

[[folder:Former [=BAU=] Members]]

!! Jason Gideon (Creator/MandyPatinkin)

One of the founding members of the [=BAU=], Gideon served as an older, experienced wise mentor-type team member in the first two seasons of the show. Though intellectual and slightly eccentric, he was still much more grounded than Dr. Reid.

* {{Archenemy}}: He and Frank.
* AloneWithThePsycho: The Footpath Killer in "Extreme Aggressor" and "Compulsion".
* AwesomeByAnalysis: Took a very intellectual approach to the work, compared to the more hands-on approach of some of the team members.
%%* BadassGrandpa
* BusCrash: [[spoiler:Gideon hadn't been in contact with the BAU for years, so it was very surprising to see his cabin again in the recent episode "Nelson's Sparrow." Then we find out it's because he's the VictimOfTheWeek. Cue an ItsPersonal TearJerker for the entire team, especially Reid. Counts as a BusCrash rather than a BackForTheDead because the corpse is always covered by a sheet.]]
* TheChessmaster: Could beat Reid in chess.
* DarkAndTroubledPast: One of the main subplots of the pilot episode is Hotch having to decide if Gideon is a risk in the field, due to an incident in Boston where he caused the deaths of six agents and his subsequent nervous breakdown.
* DefectiveDetective: Has PTSD from pre-series case.
* FBIAgent: Of course.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Melancholic
* GuileHero: As an experienced and skilled profiler
* ItsPersonal:
** [[TwoWords One Word]] - Frank.
** The bomber in "Won't Get Fooled Again" turns out to be a copycat of the imprisoned Adrian Bale, the guy who killed Gideon's original team.
* LeavingYouToFindMyself: The in-series reason for Gideon leaving.
* MysteriousPast: A lot about him is never revealed. He has a son, but it's never made clear what his relationship with the mother was, and where literally every other main character has had their youth delved into at least a little, his remains a complete mystery.
* NotSoDifferent: Frank implies the two of them are.
* ParentalSubstitute: The closest thing to a father Reid had, which made the abandonment all the more heartbreaking.
* RealLifeWritesThePlot: The reason Gideon disappears without a trace is because actor Creator/MandyPatinkin couldn't take the constant emotional impact of the horrific cases on the show.
* SickEpisode: In "Blood Hungry" he's stuck at headquarters due to a skydiving accident.
* TheStoic: To a lesser degree than Hotch, but capable of keeping cool even when having a shotgun pointed at his face.
%%* TheStrategist
* TeamDad: Though he doesn't actually want you calling him "dad", as he informs Elle.
* ToKnowHimIMustBecomeHim: All the time.
* WalkingTheEarth: After leaving the bureau, he abandons his cabin and is last seen traveling the country on a personal quest of self-discovery. [[spoiler: At some point he goes back to living in his cabin, where he is murdered by an old [=UnSub=] from one of his earliest cases]].

!! Elle Greenaway (Lola Glaudini)

The original holder of the team's HighTurnoverRate position, Elle was a member of team for Season 1 and the beginning of Season 2 who specialized in sexual offense crimes. Driven and somewhat impulsive, she served honorably but ends up leaving the team under fairly shady circumstances.

* ActionGirl: Shows herself to be this not even a minute into her first appearance. Not afraid to take on the [=UnSubs=] directly
--> '''Elle''' What's the matter, Scotty? Can't deal with a woman who's not afraid of you?
* BrainyBrunette: Very intelligent, in Extreme Aggressor she figures out they are following a decoy due to the way he is driving - and of course intelligence is a given in her line of work.
* BrokenBird: After the events of The Fisher King [[spoiler: she is shot in her own home and brought back from the dead, left with PTSD that is triggered when she goes undercover to catch a rapist, costing the team the case... so she shoots him to stop him from raping anyone else.]]
%%* BecomingTheMask
* ButNowIMustGo: Something of a darker variant- after [[spoiler: getting shot by the Fisher King]], she feels that the team let her down, and she dreads the advent of new cases while she used to love them, so she quits the team, knowing that she simply can't do the job anymore.
* DarkAndTroubledPast: [[spoiler: Raped when she was younger.]]
* DeadpanSnarker: The amount of one-line zingers she gets off is amazing. It also helps that she's got the timing and tone down pat as well.
* DrowningMySorrows: After the events of "The Fisher King", there's at least one scene where she drinks quite a bit.
* FallenHero: As a result of her own trauma. She even gets PTSD.
%%* FairCop
* FBIAgent: Like all the team members.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Choleric
* {{Foreshadowing}}: In one episode in Season 1, she said that when she worked in Sex Crimes, she saw dozens of offenders get away with it. [[spoiler: In season 2, she KNOWINGLY fucks up and a rapist gets away with it- so she follows him home and kills him.]]
* GenreSavvy: When she quits, the first thing she says after handing over her badge and guns is "This is not an admission of guilt."
* GroinAttack: How she gets the unsub from "Broken Mirror" to tell her where the girl he abducted is. When Reid wonders how she got him talking later on, Gideon suggests that its best not to think about it.
* TheGunslinger: After the events of "The Fisher King", she wears double holsters, totalling two guns in easy reach.
** She had her double holster as early as "The Fox" (1x07)
* ImportantHaircut: Gets one after returning to work after the events of "The Fisher King".
* InstantDeathBullet: [[spoiler: Averted. After she's shot by the Fisher King, she actually remained lucid long enough to dial 911, and while the King thought he'd killed her, she got through it.]]
* ItsPersonal: Violence against women and sexual assaults. After [[spoiler: "The Fisher King"]], it's also people getting attacked at home.
* IWishedYouWereDead[=/=]NeverGotToSayGoodbye: The last thing she said to her father before he was killed in the line of duty was "I hate you!", though it should be noted that she was about eight at the time.
* KarmaHoudini: [[spoiler: Rapist or not, she mercilessly killed a man and got away with it. Hell, she didn't even get fired, she quit voluntarily- and she told Hotch that if she had to do it again, she wouldn't change a thing.]]
%%* KnightTemplar
* MadeOfIron: See InstantDeathBullet. In addition, [[spoiler: the paramedics said 'we might lose her again', implying that she actually died but they brought her back.]]
* MoralMyopia: [[spoiler: Aside from apologizing at her father's grave, she shows no regret whatsoever for murdering the [=UnSub=] in "Aftermath", and argues that the other team members would've done the exact same thing if they had been put in a similar situation. Before that, she blames the local police for not being able to prevent the [=UnSub=] from raping a woman in her own home, even though they had no legal reason to break into her house. Finally, she blames the team for being shot because they weren't there for her, even though none of them could be expected to guard her in her own house.]]
* NeverMyFault: [[spoiler: The only reason the [=UnSub=] got away in "Aftermath" is because Elle confronted him before he did something that would have given the team legal cause to get his DNA. Despite this, Elle acts like the [=UnSub=] getting released is a failure of the system, and never admits that it was her carelessness that allowed him to be released in the first place. She even says that she would do the exact same thing again, apparently preferring to be a murderer to easily putting the guy behind bars.]]
* NotSoDifferent: [[spoiler: Her unshakeble conviction that she did the right thing in killing the [=UnSub=] in "Aftermath", ignoring any alternatives and making numerous leaps in logic to convince herself that it was the only way is scarily similar to how many [=UnSubs=] justify their actions.]]
* RapeAsBackstory: [[spoiler: When she was younger. One of the reasons she works sexual crimes.]]
* SpicyLatina: Her mother is Cuban and Elle displays many of the qualities that are a part of the trope, especially being able to take care of herself and confrontational tendencies.
* ThousandYardStare: Sports one when she comes back to the team.
* VigilanteExecution: "The Aftermath". After accidentally fucking up and letting the [=UnSub=] walk, she follows him home and shoots him.

!! Jordan Todd (Meta Golding)

An FBI media liaison who took over J.J.'s duties while she was gone on maternity leave. Having dealt mostly with general enforcement and non-violent crimes, she was understandably disturbed by the serial murders and other extreme crimes investigated by the [=BAU=].

* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Phlegmatic
%%* TheHeart
* HeroicBSOD: Her arc on the show is basically her descent into this.
* MoralityPet: Serves as one to remind the audience (and the team) that most people find what the BAU does to be a horrible job and cannot cope with the constant mental trauma.
* SheCleansUpNicely: Not that Meta Golding was unattractive before, but going undercover in "52 Pickup" gives her a chance to look extremely pretty.
* SkewedPriorities: In "52 Pickup", Jordan lies to the mother of a victim, telling her that her own sister was killed and her mother wouldn't help the police, pressuring the mother into letting the sister of the victim talk to the FBI. Hotch calls her out on it and delivers a blistering verbal smackdown. She gets herself back on track by teaming up with Prentiss to go undercover and catch the [=UnSub=].
* SuspiciouslySimilarSubstitute: For JJ, while she was on maternity leave.
* TemporarySubstitute: For JJ's maternity leave.

!!Ashley Seaver (Rachel Nichols)

An FBI trainee who was temporarily brought onto the team for the duration of Season 6 to fill the position left open by J.J.'s [[spoiler: and later Prentiss']] temporary departure. She was recruited into the team due to her unique insight into the psychology of serial killers, due to the fact her father was a serial killer himself.

* [[CaptainObvious Agent Obvious]]: Seems to be her main role on the team.
%%* [[AscendedExtra Ascended Guest Star]]
%%* BrokenBird
* CharacterDepth: Quite a bit. We learn a good deal about her in her introductory episode.
* EmotionlessGirl: Comes off as this at first.
* {{Expy}}: Ashley is ''very'' similar to Rebecca Locke from ''Series/TheInside'', another young [[TheProfiler profiler]] played by Rachel Nichols. Substitute "[[spoiler:my daddy was a serial killer and I have issues]]" for "I was kidnapped by a serial killer and I have issues".
%%* FauxActionGirl
* FBIAgent: In training, at least.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Leukine
* InformedAbility: Despite supposedly great marks at the Academy, she shows quite a lack of judgment toward the climax of her debut episode.
* ParentalIssues: Hoo boy. [[spoiler: Daddy was a serial killer.]]
* ParentalSubstitute: Rossi is hers. Ironically, he captured her real father.
* PutOnABus: Transferred to another unit. Prentiss and JJ are happy for her, at least.
* TheWatson: Her main role on the team, due to her status as the rookie newcomer.

!! Emily Prentiss (Paget Brewster)

[[HighTurnoverRate The team's 7th member slot has often been shifting for the duration of the entire show]]. Of all the characters who have had the position, Emily Prentiss held it for the longest period of time, for almost a full 6 seasons. The daughter of a prominent U.S. diplomat, Prentiss is fluent in several languages, is knowledgeable about many foreign cultures, and [[spoiler: was formerly an international undercover agent of Interpol prior to her time in the FBI.]] She joins the team early in Season 2, taking the position left open after Elle Greenaway resigns after her [[spoiler: vigilante execution of the serial rapist in "Aftermath"]].

* ActionGirl: Not one to sit back and solve issues by analysis alone.
* AgentMulder: Especially in "Demonology", where she's the one to bring up the exorcism angle.
* BigSisterMentor: Towards Ashley Seaver.
* BoobsOfSteel: She's not as busty as Garcia, but each one is still roughly the size of her head. Fittingly, the episode that shows this off most, "Lauren," is also when she's at her most {{Badass}}.
* BrainyBrunette: Like all profilers, she's highly intelligent.
* BreakTheCutie: All through her story arc involving Ian Doyle. Also, the writers sometimes seem committed to literally breaking her, as she is the team member most likely to have to endure a savage beating.
* TheBusCameBack: Returned for the 200th episode.
* CommutingOnABus: Luckily, only for part of season 6.
* CoolBigSis: To Reid, especially after [[spoiler: her return from the dead]].
* DarkAndTroubledPast: Druggie friends, a neglectful mother, disappeared father, and an [[spoiler: abortion at fifteen]]. Not to mention [[spoiler: her time as an undercover operative tracking terrorists for Interpol]].
* DeadpanSnarker: Probably the preeminent snarker amongst the cast.
* DeathFakedForYou: To deal with Doyle
* DisappearedDad: We know a lot about Prentiss's mother, the Ambassador, but her father is never mentioned.
%%* EeriePaleSkinnedBrunette
* {{Expy}}: Well, she's '''not''' an expy, but she ''did'' inspire the BBC to create Yvonne Rippon, a pretty clear-cut {{Expy}} of her, on ''Series/{{Casualty}}'' (played by Rachel Shelley).
* FairCop: Most of the time, but especially when she's undercover in "52 Pickup".
* FakingTheDead: To deal with Doyle.
* FBIAgent: Until she leaves for England.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Melancholic
* GoodGirlsAvoidAbortion: Subverted. We find out in "Demonology" that Prentiss got pregnant in Rome when she was 15, and had an abortion. While she does show regret that she endured that time in her life without much in the way of support, she is never shown to be "damaged" in any way from the decision. Rather, it is the reaction of the Catholic church and the ignorance of her mother that is the problem.
* {{Goth}}: In high school.
** Also, EightiesHair.
* HeroicSacrifice: Subverted. With the exception of JJ and Hotch, the whole BAU team thinks Prentiss died from her encounter with Doyle, and there is a funeral. At the end of "Lauren" however, it is clear that Prentiss is in fact still alive, but in Witness Protection.
* HonorBeforeReason: Some of her behavior in "Valhalla" and "Lauren".
* ICannotSelfTerminate: In "Lauren", she tells Morgan, "Let me go", which prompts a NoOneGetsLeftBehind response from him.
* ItsPersonal: Politics ("Honor Among Thieves") and violence against women (especially rapes, as in "Slave of Duty"). "The Thirteenth Step" starts the Ian Doyle arc, which is played out until "It Takes a Village".
* IWasQuiteAFashionVictim: Prentiss's {{Goth}} look in high school is played for laughs:
-->'''Prentiss''': What'd you do to it?\\
'''Garcia''': Do?\\
'''Prentiss''': You obviously photoshopped it or something. I mean, that hair!\\
'''Garcia''': Oh no, Pussycat, that's all you. Garfield High, class of '89.\\
'''Prentiss''': You really didn't change anything?\\
'''Garcia''': I hacked it as is. You trying to tell me you seriously don't remember rocking that look?\\
'''Reid''': Perhaps your lack of recognition stems from a disassociative fugue suffered in adolescence. Like, say, at a Siouxsie and the Banshees concert?
* NearDeathExperience: Reveals in "Epilogue" that when she coded in the ambulance in "Lauren", all she felt was cold and darkness. Being a very lapsed Catholic, she says she desperately wants to change.
* OlderThanTheyLook: According to her [[spoiler:fake tombstone]], she's in her forties, and Prentiss is actually a year younger than the actress who plays her.
* ParentalSubstitute: To [[spoiler: Declan Doyle]], though not at all in the way his father intended.
* ParentheticalSwearing: Usually directed toward [[TyrantTakesTheHelm Strauss]]. Only Prentiss can make the address "ma'am" sound like "fuck you, you soulless bitch".
** She also gives Hotch a rather icy "sir" in "Sex, Birth, Death" when he touches a raw nerve by accusing her of playing political games.
** And her response of "And also with you" (to unsub Father Paul's condescending "May God's love be with you") is delivered in a tone that sounds more like a spit to the face.
* PutOnABus: But it's a happy ending for her as she's now the head an Interpol team.
* ShipTease: For a series that is strictly NoHuggingNoKissing among the main cast, she gets quite a bit with Reid, Hotch, and Morgan. Especially Reid.
* SugarAndIcePersonality: Cold and sarcastic towards most people and prefers living alone with her cat to an unsatisfying love life, but definitively caring toward the rest of the team.
* ThisIsGonnaSuck: Her response to going "undercover" in "52 Pickup".
* TookALevelInBadass: Sure, we always knew Prentiss was badass, but in her Doyle story arc she suddenly becomes a superspy when she [[spoiler: turns out to have been an undercover operative for Interpol; over the course of her final episodes she winds up going rogue, staring at the door all night with her gun out, tossing grenades into [=UnSubs=]' cars and spraying them with machine-gun fire, and shooting hood rats in the ear. To say nothing of her badass change in wardrobe at the end of "Valhalla".]]
* WhatHappenedToTheMouse: The [[spoiler: scarification shamrock]] inflicted by Doyle seems to have magically disappeared.
* [[WhenYouComingHomeDad When You Coming Home, Mom?]]: While it's never really confirmed, Emily Prentiss does not have a good relationship with her mother, and has implied numerous times that Ambassador Prentiss was neglectful toward her (most notably in "Honor Amongst Thieves", when she's surprised the Ambassador would go to her, and in "Demonology", [[spoiler: when she says her mother "would have killed" her if she'd found out Emily was pregnant and had an abortion]]). It really doesn't get much more neglectful than [[spoiler: failing to attend your own daughter's funeral.]]

!! Dr. Alex Blake (Jeanne Tripplehorn)

A linguistics professor and experienced FBI agent, formerly a contemporary of Rossi, Strauss, and [[spoiler: John Curtis]]. One of the agents working on the infamous Amerithrax case, her career was badly damaged in the aftermath of the case's failure, and she had to spend the past decade working her way back into the FBI's good graces, with her assignment to the [=BAU=]'s lead team in Season 8 and Season 9 (to fill the position left open by Prentiss' departure) being her "second chance".

* AloneWithThePsycho: "The Good Earth"
* BrainyBrunette: Has a PhD in linguistics.
* CunningLinguist: It's her defining characteristic, and it's come in handy several times. The best instance of this was in "The Silencer"[[spoiler:, when her knowledge of sign language was instrumental in capturing the [=UnSub=], who was deaf]]. [[{{Irony}} Ironically]] she is ''terrible'' at communicating with her own family and hasn't gone home to Kansas City in five years ([[spoiler: big brother getting killed and mom dying of cancer (in the same hospital no less)]] can do that).
-->'''Blake's younger brother''' (paraphrased): You're a big fancy linguist but ''you don't talk to us''!
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Melancholic
* PutOnABus: [[spoiler:Resigns from the BAU at the end of "Demons" due to being heavily traumatized by Reid getting shot.]]
* RightBehindMe: Her introduction to Garcia.
%%* TheStoic
* ThoseTwoGuys: Has shades of this with Reid.

The wife of team leader Aaron Hotchner, the two of them were initially a loving, stable couple, but the high time and travel demands of his job eventually began to put pressure on their relationship.

Hotchner's young son.

* DaddyHadAGoodReasonForAbandoningYou: The first half of season five.

* MoralityPet: For his dad, of course.
* MyDadCanBeatUpYourDad: According to Jack, "no one beats Daddy".
* {{Nephewism}}: [[spoiler:Hotch makes a deal with Jessica, Haley's sister, that she will help him raise Jack. We have yet to see any ramifications of this.]]

!! Detective Will [=LaMontagne=] (Josh Stewart)


A N'orleans detective who assisted the team on an early case, he returned to participate in a couple other cases and eventually became the love interest and later husband of J.J.

* AscendedExtra: Originally only meant to appear in "Jones," when A.J. Cook became pregnant, the writers had to create a love interest for her quickly, and remembering her chemistry with Will, brought him back to be her mate.
* TheBigEasy: But not quite avoiding stereotypes.
* ADayInTheLimelight: While "Hit" and "Run" don't focus entirely on him, he plays a huge role in the story and we learn a lot about him.
* EvenTheGuysWantHim: [[DiscussedTrope Discussed]] on British radio.
%%* FairCop
* FunetikAksent: Has a thick Louisiana accent.
* HappilyMarried: Maybe not married, but certainly living with JJ, and it's kind of adorable. Official, as of "Hit/Run".

* RealLifeWritesThePlot: His entire existence is thanks to this. J.J.'s pregnancy was written in after A.J. Cook got pregnant. Henry is even played by her actual son.
* SatelliteCharacter: To J.J.

!! Kevin Lynch (Nicholas Brendon)

A fairly nerdy FBI computer technician, who was a co-worker of Garcia's and eventually her love interest for several seasons.

%%* BigEater
* TheBusCameBack: Shows up again in the 200th episode.
* ButtMonkey: He is, after all, played by TropeNamer Nicholas "Xander Harris" Brendon.
* EleventhHourRanger: Joins the team in "Penelope", [[spoiler:when Garcia is in the hospital]], then again in "100" to help catch the Reaper, and again in "Hit/Run" to run backup for Garcia during the bank takeover.

* PutOnABus: He and Garcia break up after she turns down his proposal of marriage; while he probably hasn't actually ''gone'' anywhere, we no longer see him very much.
* TemporarySubstitute: For Garcia in "Penelope".

!! Section Chief Erin Strauss (Jayne Atkinson)

The Section Chief for the entire [=BAU=], and thus the team's immediate superior, Strauss' role fluctuated between being an ObstructiveBureaucrat and ReasonableAuthorityFigure, though the team generally saw her as more of the former rather than the latter due to the political pressure she often put on them.

* TheAlcoholic: Revealed to be one in season seven.
* BaitAndSwitchTyrant: She has the occasional, ''very rare'' PetTheDog moments. Recently, after her [[TheBusCameBack return]], she's become much more [[ReasonableAuthorityFigure reasonable]].
* BelligerentSexualTension: At times her interactions with Rossi come off as this.
* DependingOnTheWriter: In her first appearances, she's trying to be a [[ManipulativeBastard manipulative bitch]]. Then it look like she is [[TyrantTakesTheHelm A Tyrant Taking The Helm.]] In her next appearance, she becomes a BaitAndSwitchTyrant and gets a few PetTheDog moments. Then she's back to the ObstructiveBureaucrat boss who does things over the team's objections. Now she's politicking while still giving the team a chance to do things their way, and at times seems to be trying to make up for previous jerkish behavior.
* {{Expy}}: A GenderFlip of [[Series/HolbyCity Henrik Hanssen]], same personality traits.
* FaceDeathWithDignity: [[AvertedTrope Nope.]] She's crying and wants her kids and wishes she had [[spoiler: died]] before allowing the baddie to humiliate her.
* FBIAgent: Of the supervising sort
* GenreSavvy:
** In "It Takes a Village", she knows as soon as Emily asks for permission to [[spoiler: trade Ian Doyle for Declan]] that the BAU's already set the plan into motion.
** In "The Replicator" it is revealed that [[spoiler: she already suspected that the [=UnSub=] was FBI insider and modified one of her team's reports, knowing that the [=UnSub=] would give himself away as having read said reports (the accessibility of which is privy only to a select few) by unknowingly using in one of his recreations the false detail she inserted]].
* IronLady: As a supervisor of the team, plays this role.
* JerkWithAHeartOfGold: She comes off as a politically-minded ObstructiveBureaucrat, but there are a great number of instances where it's clear that she's actually just trying to help/protect the team.
* ObstructiveBureaucrat: Started out as one, before becoming more of a supporter of the team.
* PetTheDog: Surprisingly, in "100", after spending the entire episode [[spoiler: investigating the events around Haley Brooks Hotchner's death and Hotch going off the rails, interrogating the team and trying to pin the blame on Hotch, she's in tears after Hotch's testimony, and refuses to pursue the matter any further]].
* PutOnABus: [[spoiler:Left for rehab; see TheAlcoholic above]]. She's back [[spoiler: and better]] as of "Hit/Run." Well, [[spoiler:before "The Replicator," anyway.]]
* StayWithMeUntilIDie: After being fatally poisoned by the Replicator, she asks Hotch to stay with her so she won't [[DyingAlone die alone]]. [[TearJerker He does.]]

!! Diana Reid (Jane Lynch)


Spencer Reid's mother, who did her best to raise him from a very young age after his father fled the family, despite her severe paranoid schizophrenia.

* BrokenBird: Severe paranoid schizophrenic who had to be committed to a sanitarium by her then-eighteen year old son. Has just as brilliant a mind as Spencer, under the delusions and medication. [[spoiler:It's implied that part of her mental breakdown was the result of seeing a friend of hers kill Gary Michaels, a pedophile who killed Riley Jenkins and targeted Spencer.]]
* ConspiracyTheorist: Of the "government is watching me and my son works with fascists" variety.
* CoolTeacher: Was once a university professor, before the schizophrenia.
* MamaBear: The Instincts/In memoriam two-parter makes it very clear that she would never let anything hurt her son. Or have him stay in a mental institution for longer than a one night visit. [[spoiler:When he asks her about Riley Jenkins, she tried her best to avoid talking about him, especially since her own son could have ended up like him.]]
%%* TheSchizophreniaConspiracy
* SocialServicesDoesNotExist: Spencer's father left the family when he was very young, so Diana raised Spencer single-handedly. Apparently social services felt that it was totally okay for Spencer's sole guardian to be an unstable paranoid schizophrenic who thought BobDylan was spying on her.

!! Carolyn Baker Rossi (Isabella Hoffman)

* AmicablyDivorced: She even kept her husband's surname.
* DiedInYourArmsTonight: Rossi is with her when she dies.
* NewOldFlame: Though Rossi had already mentioned his divorces.

* StockholmSyndrome: Averted, thank God.

[[folder: Recurring and Multi-Part Episode [=UnSubs=]]]
!! Karl Arnold, The Fox (Neal Jones)

A family psychiatrist and VillainOfTheWeek serial killer who would use his small size to sneak into the homes of his patients, forcing them to treat him as their father before killing the entire family, due to issues he had with his own family (his wife had divorced him and got full custody of the children). The [=BAU=] consult him in prison regarding another family annihilator [=UnSub=] with a similar M.O. as his, only to discover it's a ploy by the Reaper to taunt Hotchner and announce his endgame.

* GrievousHarmWithABody: When cornered, he threw ''a baby'' at Gideon.

* KnifeNut: Stabbed mothers and children to death.
* KnightTemplar: He thought that not only he had to punish families he saw as dysfunctional, but also that he had to [[ForcedToWatch show the father]] what happens when "the head of household isn't strong".

%%* NeatFreak

The villain of the Season 1 finale. A wealthy, deformed psychotic with a flare for the dramatic, Garner learned of and became inspired by the [=BAU=]'s exploits and, styling himself as "the Fisher King", set up a high-stakes life-or-death quest for them based on Arthurian legend.

* FairyTaleMotifs: He's the Fisher King, his surviving daughter is the grail, and the BAU are the Knights of the Round Table.

* WoobieDestroyerOfWorlds

!! Carl Buford/Mohammed Alam (Julius Tennon)

A football coach and pillar of the community who was secretly a child molester. Most notable for having molested [=BAU=] team member [[spoiler: Derek Morgan]] as a child. Like Karl Arnold, he is interviewed in prison in a later episode to gain insight into a new series of crimes seemingly connected to his own original crimes.

* CatchPhrase: [[spoiler: "Look up to the sky." In "Restoration" Morgan revealed that this was what he used to say to him as he molested him and possibly many of his other victims too.]]
%%* FatBastard
* KarmicDeath: After the [[spoiler: other inmates discover what he really did]] they [[spoiler: murder him]].
* SerialKiller: He only killed three people but what's worth mentioning is his list of children that he molested in the 80s. According to the Criminal Minds Wiki there are 54 names [[spoiler: including Derek Morgan's]] on that list. With 4 others (one in the 90s and three in the 00s) this makes him the most prolific child molester seen on the show.

* TokenMotivationalNemesis: To Derek Morgan
* VillainOfTheWeek: Of "Profiler Profiled".
* VillainWithGoodPublicity: Known for coaching a football team of troubled youths,

!!Frank Breitkopf (Creator/KeithCarradine)

The show's original recurring villain, Frank was a psychopathic serial killer who traveled from state to state, abducting victims at random and killing them by dissecting them alive. With no specific preference in victim type (and thus no pattern for law enforcement to notice), he was able to stay off the radar and continue killing for decades, becoming the most prolific serial killer ever encountered by the [=BAU=] (until their discovery of Billy Flynn, the Prince of Darkness, a few years later). He had an intelligent, eerily calm demeanor as well as a fondness for elaborate XanatosGambit schemes, as discovered by Gideon and the [=BAU=] when they finally try to confront him.

* AndIMustScream: Puts his victims in this state via drug that leaves them paralyzed, but fully conscious as he slowly vivisects them... in a room with a mirrored ceiling.
* {{Archenemy}}: Fixates on Gideon as one. It quickly becomes mutual.
* BigBad: Of Season 2.
* BreakingSpeech: Loves giving these to Gideon.
* CallingCard: Taking a right rib bone and making wind chimes out of them.
* DepravedBisexual: Downplayed. He doesn't care what gender his victims are and seems to have or at least really want to be in love with Jane. He also thinks Morgan's pretty: "If I had your looks, do you know how much easier my life would be?" "Beauty can cover a multitude of sins, but underneath we all look exactly the same."
* DrivenToSuicide: [[spoiler: In No Way Out II: The Evolution of Frank, he and Jane jump in front of a train when he is cornered by the FBI.]]
** [[spoiler:TakingYouWithMe]]
* EmotionEater: Like the Reaper after him, Frank requires his victim's fear to feed off of. He spared Jane's life because she wasn't afraid of him when he captured her (due to her believing he was an extraterrestrial who wanted to study her), and claims to have fallen in love with her due to this.
* EvenBadMenLoveTheirMamas: Subverted. While he kept his mother's body in a pristine apartment, and surrounded it with flowers, it's heavily implied that she was his first victim.
* EvilGenius: Though he probably never received any formal education, he's very intelligent and sets up an elaborate plan to outsmart the FBI in order to get what he wants. He also has a compulsive need to memorize facts, and recites them when engaging in his CriminalMindGames.
* FauxAffablyEvil: He's polite and soft-spoken, but he's not a nice person at all.
* FinalBoss: Of Season 2.
* FirstNameBasis: He always calls Gideon by his first name and introduces himself by his.
* FreudianExcuse: His mother was a prostitute, who he witnessed perform and have performed on her every indignity imaginable.
* ItsPersonal: Killed Gideon's old flame, then started targeting people he had saved in the past.
* [[spoiler:KarmaHoudini / TheBadGuyWins: Dies how he wants, is TogetherInDeath with Jane, and posthumously sends Gideon over the DespairEventHorizon and out of the BAU forever.]]

* MeaningfulName: Points out that his name is derived from a type of spear and Gideon shares his with a Greek Hero and a biblical figure.
* MoralityPet: Jane.
* NotSoDifferent: Implies that he and Gideon are this.
* NotSoStoic: The ever so brief look he gives when Gideon mentions they've learned who his mother is, and what his childhood was really like.
** Lividly yells at a cop who seemingly subdues Jane too hard.
* ThePlan: Pulled off successfully in "No Way Out", but he's OutGambitted in "No Way Out II".
* RecurringCharacter: In Season 2
* RippedFromTheHeadlines: real-life torturer David Parker Ray filled his trailer with medical implements and a mirrored ceiling and drugged his victims to cause amnesia.
* SelfMadeOrphan: In "No Way Out II: The Evilution of Frank", the team discovers his mother's corpse in his apartment and it's implied that he killed her.
* SerialKiller: That goes without saying but Frank took it to a whole new level. He's killed at least ''166 people'' all over the United States for at least thirty years, though it should be noted he's nothing compared to Billy Flynn and a few RealLife serial killers.
* SmugSmiler: Sees himself as better than everyone else.
* SmugSnake: The poster boy. He manages to make sitting in a diner drinking a strawberry milkshake look arrogant.
* TheSociopath: He feels no remorse for the people he kills and is incapable of empathy.
%%* SonOfAWhore
* TheSouthpaw
* StartOfDarkness: "No Way Out II: The Evilution of Frank".
* StalkerWithACrush: He developed an unhealthy obsession with Jane when he was about to torture her. "Fortunately" for him, she developed a form of StockholmSyndrome and returned his obsessive feelings.
* ThatOneCase: For Gideon, apparently even before "No Way Out".
* TooGoodForThisSinfulEarth: Espouses a belief akin to this before killing himself and Jane.
* TortureTechnician: Tortures his victims with knives.
* WhatIsThisThingYouCallLove: Can't feel it, but wants to.
* WickedCultured: Enjoys classical music, ornithology, literature, names and has an interest in mythology. He'd be interesting to spend time with if you could get past the whole "Cuts people open" aspect of his personality.
* WouldntHurtAChild: Well, not ''directly''...
* WorthyOpponent: Sees Gideon as one of the few people who deserves to catch him.
* {{Yandere}}: He won't stop until he has Jane back.

!!Tobias Hankel/[[spoiler:Charles Hankel/Raphael]] (James van der Beek)

The villain of the two-part episode "The Big Game" and "Revelations" early in Season 2. A telephone computer tech support worker [[spoiler: suffering from multiple personalities]] involved in the murder of several people perceived as engaging in the 7 deadly sins. Most notable for his kidnapping and torture of Spencer Reid.

* AbusiveDad: His father is a contender for worst parent in the entire series. The [[spoiler:Charles personality is modeled after him, and compulsively abuses anyone who comes into his power.]] So bad in fact, that when the BAU informes Tobias' sponsor [[spoiler:they believe Tobias killed his father, he replies "Good for him."]]
* ArchangelRaphael: [[spoiler:The Raphael personality believes himself to be the angel in question.]]
* {{Archenemy}}: Fans tend to see him as Reid's and not without reason. While he doesn't have the arc that Frank, The Boston Reaper, or Ian Doyle recieve, no other [=UnSub=] has ever had this sort of impact on Reid. Between traumatising him, getting him addicted to dilaudid, and making DID his personal BerserkButton, Tobias is still with Reid seasons later. That being said, Reid clearly empathizes with Tobias. [[spoiler:The Charles and Raphael personalities, not so much]].

!! Deputy Jason Clark Battle (Bailey Chase)

A charming stranger at the coffee shop who asks Garcia out on a date after she helps him fix his broken laptop in the episode "Lucky". The date goes well up until he suddenly pulls out a revolver and shoots Garcia in the chest at the end of the episode. In "Penelope", he's revealed to be a local sheriff's deputy who would secretly shoot random bystanders then step in as the first responder in order to be a hero. He stalked Garcia with the intention of killing her due to the (mistaken) belief that she was about to discover his criminal activities due to her coincidentally examining several of the cases he was involved in.

* BoomHeadshot: [[spoiler: How he dies]].
* CreateYourOwnVillain: As it turns out, Garcia has been overstepping her authority by flagging the unsolved murders of loved ones in her bereavement support group. Two of those murders happened to be Jason, who assumed the FBI was onto him and went after Garcia. He was a killer before, but he probably would have stayed hidden and left Garcia alone if she hadn't drawn attention to herself.
%%* HotGuysAreBastards

* ManOfWealthAndTaste: Attempts to give this impression.
* RevolversAreJustBetter: Uses a large caliber revolver. When Morgan notes the unusual nature of it, Reid muses that it's because it ensures he wont leave bullet casings at a crime scene. A gun shop owner comments that revolvers don't hold many bullets, but he counters that's irrelevant if you don't miss.
* SuicideByCop[=/=]TakingYouWithMe: Once he realizes his number's up, the only thing he wants to do is take as many FBI down with him as possible. [[spoiler:The only casualty is him, as he didn't count on JJ gunning him down from behind]].
* ThatOneCase: For Garcia.
* VillainOfTheWeek: Of "Penelope".

The first major ArcVillain of the show. An infamous serial killer driven by power, control, and manipulation who terrorized the Boston area 10 years ago, and who was the subject of Hotchner's first case as team leader of the [=BAU=]. Similar to the Zodiac Killer (who he was based off of), the case was never solved. The [=BAU=] finally uncover his identity in "Omnivore", only for him to pull off a daring escape at the end of the episode. He personally assaults Hotchner in his home at the end of Season 4, and continues to stalk Hotchner and his family for the duration of Season 5 until a final confrontation in the show's 100th episode.

* [[AbusiveParents Abusive Father]]: Plus neglectful mother equals screwed up kid. It's implied, or at least believed by Hotch, [[spoiler:that he sabotaged their car, leading to the accident that killed them]].
* {{Archenemy}}: To Hotch, whom he fixates on as his "nemesis."
* ArcVillain: First appears in Season 4, personally attacks Hotchner in the final episode, then menaces him and his family for most of Season 5 until Hotchner finally confronts him in "100".
* [[spoiler: AssholeVictim]]: [[spoiler: In "100", after finally pushing Hotch too far, Hotch finally puts an end to his reign of terror by violently beating him to death]].
* {{Back from the Dead}}: For an appearance in Season 9, when [[spoiler: Hotch collapses and hallucinates a trip to the movies with Foyet and his wife]].
* BadassLongcoat: Wears a black trench coat while dressed up as the Reaper.
* BiggerBad: In "Nameless, Faceless" and "[[spoiler: Outfoxed]]"
* CallingCard: The Eye of Providence and/or the word FATE; also had a habit of taking something from his victims and leaving the object at the scene of the next murder.
* ColdBloodedTorture: Hotch and Marshal Kassmeyer.
* ControlFreak: Gets off on controlling and domineering others.
* CrazyPrepared: He spent the decade he was on hiatus obsessively prepping for the possibility he would be caught. He created fake identities, stockpiled weapons, and memorized the blueprints of every police station, jail, and courthouse in Massachusetts in preparation for an escape.
* CrimefightingWithCash: An inverted, evil version. His activities as the Reaper were helped considerably by the inheritance he received from his wealthy adoptive parents. While his actual killings didn't require ''that'' much in the way of money, his wealth helped him establish a large number of safe houses, alternate identities, and weapon stockpiles in preparation for the day when he would need to disappear from the grid after his identity is revealed, giving him the resources to stalk Hotch from the shadows throughout Season 5.
* CriminalMindGames: He likes to send taunting messages to the press and the cops.
%%* DangerouslyGenreSavvy
* DarkIsEvil: Always dresses all in black when he's in his Reaper persona.
* DiscOneFinalBoss: In Seasons 4 & 5, where FinalBoss credits are taken by Mason Turner and Billy Flynn respectively.
* EmotionEater: The BAU profiles him as feeding off his victims' fear. He doesn't kill Morgan after knocking him out due to being unable to intimidate him while he's unconscious, and Hotch makes a point of never showing him fear when confronting him later.
* {{Ephebophile}}: Rossi profiles him as one, due to the disproportionate amount of time he spends with his younger female victims (knifed anywhere from ten to ''sixty-seven'' times), as opposed to his male and older female victims (all simply shot, [[ColdBloodedTorture except for Hotch]]).
* EvilCripple: To a degree. The damage he inflicted on himself requires a massive cocktail of drugs to be administered daily if he doesn't want his organs to start shutting down.
* EvilisPetty: Considering that he had already killed plenty of people and achieved the fame that he desired, and he even could've gotten away if he wanted, [[spoiler: it was entirely unnecessary for him to actually kill Hotch's wife; even more so with his plan to murder Jack.]]
* EvilOrphan: Adopted by a wealthy family after his parents died. It didn't improve him.
* FalseReassurance:
-->'''The Reaper:''' Shhh. I'm not going to shoot you. Shhh.\\
'''Nina Hale:''' Thank you.\\
'''The Reaper:''' You're welcome. ''(Takes out a knife and slits her throat.)''
* FauxAffablyEvil: He often gains people's trust by pretending to be polite and friendly and even tells Hotch how he's going to kill his family in the same tone.
* {{Fingore}}: Takes delight in cutting off a man's fingers.
* TheGlassesComeOff:[[spoiler: He ditches his NerdGlasses at the end of "Omnivore" after he's revealed as The Reaper.]] He also [[BaldOfEvil shaved his head in his later appearances]].
* GutturalGrowler: Used in his debut to disguise his identity. He stops bothering after TheReveal.
* TheHeavy: For much of Seasons 4 & 5.
* HoistByHisOwnPetard: [[spoiler: Hotch [[WhatCouldHaveBeen was originally]] going to stab him to death with his own knife, but they decided to change the cause of death to ExtremeMeleeRevenge.]] In a sense, it still counts. He could have easily gotten away from the BAU if he hadn't stayed to see Hotch suffer or threaten his family.
* InTheHood[=/=]MalevolentMaskedMen: Combos a mask and hood in his Reaper costume.
* ItsAllAboutMe: Believes that Hotch has no right to hunt him down (despite his being a ''SerialKiller'') and goes out of his way to blame Hotch for his problems.
* ItsPersonal: With Hotch.
* [[spoiler: KarmicDeath]]: [[spoiler: Literally at the hands of Hotch by way of ExtremeMeleeOfRevenge]].
* KnifeNut: But also known to use firearms.
%%* KnightOfCerebus
* LackOfEmpathy: Has none for anyone.
* NoKillLikeOverkill: His young female victims were stabbed an excessive number of times (one had somewhere in the range of sixty stab wounds). The entire bus massacre scene in "Omnivore".
* RecurringCharacter: Shows up in "Omnivore", "...And Back", "Nameless/Faceless", "Outfoxed", and "100".
* RevolversAreJustBetter: His .44 magnum.
* RippedFromTheHeadlines: In "Omnivore," he's blatantly based on the Zodiac Killer: a serial killer who gives himself an [[RedBaron eye-catching alias]] and a [[CallingCard distinctive logo]], wears a CoatHatMask costume, wields both a gun and a knife, targets couples in their cars, sends [[CriminalMindGames taunting letters]] to the cops and the press, uses ciphers, targets a busload of people (although the Zodiac only threatened to do that and never actually followed through), and [[KarmaHoudini simply disappeared]] after killing for years with impunity.
* SelfHarm: Cut himself up in order to make himself look innocent.
* SelfMadeOrphan: Hotch accuses him of having murdered his parents in a [[MakeItLookLikeAnAccident fake car accident]] (at the [[EnfantTerrible age of nine]], no less). He denies it, albeit rather flippantly.
* SerialKiller: A serial spree killer to be exact.
%%* SmugSnake
* TheSociopath: Blatantly.
* ThatOneCase: For Hotch.
%%* TheUnfettered
* VillainsWantMercy: [[spoiler: In "100", after Hotch breaks Foyet's leg and pins him down with a fist to his face, he had the gall to get him to stop by saying he surrenders. Considering he just murdered Haley and seconds before started gloating about how he plans to hunt down Jack to psycologically torture him and kill him, Hotch basically tells him that he can take his surrender and shove it up his ass in the form of brutally breaking his stupid head open in the most painful way possible]].
* WhamLine: "You should have made the deal..."
* WouldHurtAChild: If Hotch hadn't stopped him, he would have probably tortured and then killed [[spoiler:Jack.]]

!! The Turner Brothers (Garrett Dillahunt and Paul Rae)

The villains of the Season 4 finale. A pair of Canadian brothers who own a farm just across the border from Detroit. Lucas, a mentally handicapped giant of a man, captures and kills homeless people from Detroit under the orders of his quadriplegic brother, Mason, to provide raw material for Mason's stem cell experiments in search of a cure for his condition.

* BrainsAndBrawn: Mason is the brains, Lucas the brawn.
* DoesNotKnowHisOwnStrength: Lucas, who tends to forget just how big he is. This is how Mason got crippled.
* TheDragon: Lucas to Mason.
* DropTheHammer: Lucas's MO. He draws an "X" on the back of his victims' necks with a marker, than smacks it with a claw hammer until they die.
* DumbMuscle: The severely handicapped Lucas.
* EvilCripple: Mason, a quadriplegic barely kept alive by a ton a of machinery.
* EvilGenius: Mason is very, very bright.
* {{Expy}}:
** Mason is based heavily on Mason Verger from ''Literature/{{Hannibal}}.'' Both are sexual sadists (though the latter is a pedophile) who were crippled by a SerialKiller (albeit in very, very different circumstances, and unlike the EvilGenius Lecter the ManChild Lucas wasn't a killer at the time) and seek humiliating revenge on them (of very different sorts though). Both have farms with man-eating pigs, and are verbally and emotionally abusive to their carers- in the novel, Verger's carer is his sister, which only adds to the similarities. Most obviously, both are named Mason.
** The Turner Brothers as a unit also have some similarities with Charles Holcombe, and his right-hand man, Steven, from Season 2. Both are serial killer teams who prey on the poor, perform surgical experiments on their victims, and believe that the homeless have no value to society. In each case one partner is also manipulating the other.
* ExtremeDoormat: Lucas' low IQ, poor social skills, and the guilt he feels over his brother's injuries makes him one wherever Mason is concerned.
* FatBastard: Lucas, although much more sympathetic than most.
* FateWorseThanDeath: How Mason views his condition.
* FinalBoss: Of Season 4.
* ForScience: How Mason tries rationalizing manipulating his mentally handicapped brother into killing the homeless for his experiments, saying that he is searching for a cure for his condition. Earns him a ShutUpHannibal from Rossi, who calls him out as just another sadistic bastard since his farm and equipment are no where near adequate for such a task, and he's arranged mirrors around the house in a way that lets him see his victims suffer from his bed.
%%* GeniusCripple: Mason.
* GentleGiant: Lucas would be this if not for his bastard brother and his own inability to handle anger well.
* GoOutWithASmile: Mason, who lies back and smiles before he is shot.
* ImAHumanitarian: Sorta. Lucas doesn't really seem to mind eating pigs that he's fed a ton of people to.
* ItsAllAboutMe: Mason doesn't give a good goddamn about anyone but himself, even willing to let the FBI kill Lucas, whom he sees as expendable.
* KarmaHoudini: [[LampshadeHanging Lampshaded]] by Rossi, who says that selling the idea that a bed-ridden former doctor is really a manipulative homicidal maniac to a jury is going to be an uphill struggle, especially since Lucas actually did all the killings. [[spoiler:One victim's brother solves the problem with a VigilanteExecution.]]
* KillThePoor: They prey on homeless people, prostitues and junkies on the premise that they're useless, and no one will miss them.
* LackOfEmpathy: Mason has no empathy for those they've killed, saying that they should be grateful that they can become a part of something greater than themselves. Subverted with Lucas, who starts empathising with the last victim after the police show up to the farm and he's forced to spend time with her in his old childhood hideaway.
* MadDoctor: Mason, with Lucas acting as his hands. He's conducting extremely primitive stem cell experiments.
%%* ManChild: Lucas, in all ways.
* ManipulativeBastard: Mason, who convinces Lucas to do the murders, and later tries to manipulate the FBI into killing Lucas and letting him go.
* MercyKill: Mason's take on Lucas' death.
* MissingWhiteWomanSyndrome: Along with the "useless to society" thing, Mason presumably had Lucas target the homeless because he believed no one would really care or notice.
%%* MotiveRant: Mason gives a pretty good one.
%%* NonMaliciousMonster: Lucas.
* NoSocialSkills: Lucas, who twitches, easily gets confused, and can barely carry on a conversation.
* PsychopathicManchild: Lucas, implied to be extremely volatile even before Mason manipulated him into killing.
* RefugeInAudacity: Mason gloats that he'll never be convicted, even with all the circumstantial evidence against him, because no one would believe that a quadriplegic was able to mastermind the torture and murder of almost 90 people from his adjustable bed.
* {{Serial Killer}}s: They've murdered 89 people in just a few years, with Kelly, whom the FBI save, as number 90.
* ShoutOut: An EvilCripple named Mason who lives in a pig farm. [[Literature/{{Hannibal}} Subtle]].
* SiblingYinYang: Lucas is a six and a half foot tall, three hundred pound DumbMuscle [[TheBrute Brute]] and PsychopathicManchild with severe retardation and Autistic tendencies, who dresses in overalls, loves the farm, and doesn't seem to understand that he's killing actual people. Mason is a short, cold-blooded EvilCripple and EvilGenius who attended [[MadDoctor med school]], wanted to move away from home, and is ''fully aware'' of what they're doing, but just doesn't care.
* SiblingsInCrime: Mason as the brain, and Lucas as the brawn
* SmugSnake: Mason, whose low opinion of his victims is matched by his high opinion of himself.
* SoftSpokenSadist: Mason, who thanks to damage to his neck, can't raise his voice.
* SympatheticMurderer: ManChild Lucas, very much so. His brother Mason, [[LackOfEmpathy not so much.]]
* VeryLooselyBasedOnATrueStory: Robert Pickton, a Canadian farmer who killed primarily prostitutes, and disposed of the remains by feeding them to his pigs.
* VigilanteExecution: Mason's death.
* VillainOfTheWeek: Of the "To Hell and Back" two parter.

!!Billy Flynn, The Prince of Darkness (Creator/TimCurry)

The villain of the Season 5 finale. Sloven and uneducated but incredibly cunning and ruthless, Flynn is a transient serial killer who travels across the country in his [=RV=], breaking into homes at night during city-wide blackouts and robbing and killing the families inside. His M.O. of only attacking at night during blackouts earns him the nickname "The Prince of Darkness" from the media once his killings finally become public knowledge. Having attacked over 200 families across the entire country, with a body count over 400, he's by far the worst serial killer ever faced by the [=BAU=].

* AllThereInTheManual: His name was revealed prior to "The Longest Night", on the "Our Darkest Hour" cast pages of sites like imdb or TV.com.
* {{Archenemy}}: The fandom tends to see him as Morgan's, for obvious reasons. Between his prominence in the show, his humiliation of Morgan in their first encounter, and the way that his murder of Detective Spicer and kidnapping of Ellie turn the entire thing [[ItsPersonal personal]] there really isn't a better candidate for the title. Morgan himself describes him this way - toward the end of "The Longest Night", when arguing with Hotch about going in to the house Flynn had just broken into, Morgan reasons with Hotch by telling him, "you had Foyet, this one's mine!"
* BookDumb: Billy's uneducated and can't spell, but he's smart enough to leave no evidence at his crime scenes, and has been getting away with home invasion, serial rape and murder since 1984.
* BoomHeadshot: How most of his victims are killed.
* TheCorrupter: To Ellie.
* DarkIsEvil: Works during a planned blackout
* DarknessEqualsDeath: Kills at night
* DrugsAreBad: Meth to be exact. It's what lets him stay up all night.
* EnfantTerrible: Killed his mother and one of her clients when he was thirteen, apparently forcing the latter to beg for his life before shooting him.
* EvilBrit: Curry can't quite suppress his British accent.
* EvilIsHammy: Especially when played by Tim Curry.
* EvilMakesYouUgly[=/=]ThePigpen: Between the drug abuse, the late nights, the high-risk lifestyle, the bad food, and constantly being on the run from the cops, Billy's a wreck, with bad posture, terrible teeth and breath, a distinctly unhealthy looking body, and baggy, bloodshot eyes.
* EvilMentor: To Ellie Spicer, teaching her how to lie, steal, and kill with the best of them.
* EvilOldFolks: Chronologically he's only in his mid-fifties, but looks a lot older thanks to two decades of smoking meth and not sleeping.
* EvilSoundsDeep: Due to being played by Tim Curry.
* {{Expy}}: Of Frank. Both are prolific serial killers, who travel from location to location, have been active for decades, have killed more victims than anyone else appearing in the show, serve as ThatOneCase for one of the agents (and the FinalBoss of a season), have one person they can empathise with, and got their start because of their prostitute mothers. Since their modus operandi, appearance, and presentation are radically different, with Frank being a smarter-than-thou SmugSnake with a professorial air, and Billy an uneducated, meth-addicted thug this is harder to notice than you'd think.
* TheFamilyThatSlaysTogether: Since Detective Spicer only had a kid because he allowed him to live years earlier, Flynn developed a kind of "grandfather delusion" towards Spicer's daughter, who he tries to make his sidekick.
* FinalBoss: Of Season 5.
* ForcedToWatch: If he's in the mood for some rape, he'll force someone (usually the victim's children) to watch. His own mother would force him to watch her have sex.
* FreudianExcuse[=/=]MonsterSobStory: His early life was truly horrible: his mother was a hooker; she made him watch, and later pimped him out to paedophilic clients. This is however defied by JJ. She refuses to empathize with him, and says that as horrible as his upbringing was it doesn't justify what he's doing. In fact it makes it worse, since he of all people knows how bad it is.
* AGodAmI: "I decide who dies, but mostly, I decide who lives. I'm like... God."
* HeelRealisation: Which prompts his VillainousBreakdown.
* LargeHam: He has some moments. Being played by Tim Curry surely helps.
* MercyKill: Over the years he eventually came to rationalize his mother's murder as this. However, he's fully aware that this version ''is'' a post-rationalization, and actually questions whether he made it up to make himself feel better, showing a level of self-reflectiveness which is ''really'' unusual for the murderers on the show.
* {{Narcissist}}: His final crime spree is motivated by a desire to take credit for [[spoiler:Detective Spicer]]'s career and he is obsessed with listening to news reports about himself (to the extent that he stops in mid-rape to listen to a news flash on the radio).
* NotSoDifferent: From Ellie, as invoked by JJ. It works.
* ParentalSubstitute: Wants to be a grandparental substitute for Ellie. She's not interested.
* PetTheDog: His release of Ellie. Even before that, his treatment of her is surprisingly gentle, given who and what he is. As Billy himself notes, "I was nice to you."
* ScaryTeeth: Courtesy of smoking lots of meth.
* SelfMadeOrphan: Killed his mother.
* SerialKiller: UpToEleven, in all likelihood having in the neighborhood of ''four hundred'' victims. For the curious, this likely makes him (within the context of the show, of course) either the most- or second-most prolific murderer ''in human history''.
* SerialRapist: He rapes the men and women alike.
* SlasherSmile: It's Tim Curry. Were you expecting any other kind?
%%* SmugSnake
* SonOfAWhore: Part of what caused his issues.
* SuicideByCop: Forces Morgan to kill him.
%%* TalkingTheMonsterToDeath
* ThatOneCase: For Morgan.
* UncleanlinessIsNextToUngodliness: The word "slovenly" comes to mind.
* VeryLooselyBasedOnATrueStory: Has some elements of Richard Ramirez, better known as the Night Stalker.
* VillainOfTheWeek: Of "Our Darkest Hour" and "The Longest Night".
* VillainousBreakdown: After hearing JJ's radio address.
* WoobieDestroyerOfWorlds: Doesn't initially act like it, being a sadist who's ended and/or ruined over ''400'' lives, but when his FreudianExcuse finally gets out, he gets more sympathetic and self-reflective--[[spoiler:even invoking SuicideByCop to let Morgan avenge said lives (and end Flynn's own mental pain).]]
* WouldntHurtAChild: Played with. If his victims have children, he'll leave them alive, but witnessing their parents' murders will inevitably traumatize them.

!! Ian Doyle, Valhalla (Creator/TimothyVMurphy)

An ArcVillain whose presence is felt throughout Season 6 of the show. A breakaway IRA terrorist and international criminal mastermind with a connection to Emily Prentiss' past. Escaping from prison early in Season 6, he begins hunting down Emily and all of her former team members from Interpol.

* AlasPoorVillain: [[spoiler:Spends his last moments apologizing to his son.]]
* AntiVillain: [[spoiler:Becomes one in "It Takes A Village", helping the BAU stop a rival terrorist to save his son.]]
* {{Archenemy}}: Doyle is to Prentiss as The Reaper is to Hotch.
* ArcVillain[=/=]BigBad: Of Season Six.
* BoomHeadshot: How most of his victims are disposed of, though he's not adverse to knives and poison.
* TheDragon: A mook named Liam appears to fill this role.
* HasAType: Brunettes, Possibly with a ruthless streak considering [[spoiler: Emily in her Lauren Reynold's persona]] and Chole Donaghy.
* ItsPersonal: Has quite the grudge against Emily, more so than anyone else he's after.
** And with good reason, too. She [[spoiler: went undercover as a fellow arms dealer, Doyle fell in love with her, proposed what amounted to marriage to her, and expressed a desire for children with her. After his arrest, he found out that she'd been a spy, and believed she was responsible for the death of his son, Declan.]]
** [[spoiler:And she was, though his death was actually faked. While trying to tell him this she accidentally makes it seem like she actually murdered the boy, which takes this trope UpToEleven for about 5 seconds, when she explains he's still alive and she had him in hiding.]]
* ManOfWealthAndTaste: A wealthy international terrorist[=/=]criminal mastermind, Prentiss notes Interpol can track him by his money trail, as he will be unable to resist living extravagantly even when on the run from every major government on Earth.
* MonsterSobStory: Doyle was led to believe that [[spoiler: his painfully adorable son had been executed, as a ploy to help the North Koreans break him.]]
* NeverFoundTheBody: [[spoiler:A big question fans are all asking--what happened to Doyle and where did he disappear to? Is he dead, or did he escape?]] As of "It Takes A Village," [[spoiler:he's gone. Permanently.]]
* OffscreenVillainDarkMatter: It's never really elaborated how a breakaway IRA terrorist can afford a huge mansion and enough firepower and equipment to run a small army, though given how much heat he was getting from Interpol he was probably involved in some very lucrative international criminal activity.
* ReallyGetsAround: The list of his exes is pretty long.
* RecurringCharacter: Appeared in several episodes
* RevengeBeforeReason: Doyle keeps threatening to kill Emily but takes so long to do it, he is thwarted--despite all outward appearances...
* RoaringRampageOfRevenge: Killing everyone responsible for putting him away, Emily included.
* StatingTheSimpleSolution: Liam does this several times.
* TattooedCrook: A four-leaf clover on the wrists of him and his followers.
* ThatOneCase: For Prentiss.
* WesternTerrorists: Headed an offshoot of [[UsefulNotes/TheTroubles the IRA]].
* WhiteMaskOfDoom: Worn by him and his {{Mook}}s.

!! Matthew Downs and the Face Cards (Evan Jones, Seth Laird, Creator/TriciaHelfer, and Josh Randall)

The villains of the Season 7 finale.

* [[AbusiveParents Abusive Grandfather]]: Implied for Izzy. [[spoiler:His name was Henry and he had blond hair, so Izzy takes her rage at him out on [[HarmfulToMinors JJ's son]]]].
* BaldOfEvil: Oliver, and Chris has a buzz-cut, as well.
* BigBadWannabe: Chris.
* DesignatedGirlFight: JJ vs Izzy, probably surpassed only by [[spoiler:Hotch vs. Foyet]] as the most epic fight the series has had so far. Also justified in that ItsPersonal: Izzy abducted Will and [[spoiler:went after JJ's son]].
* TheDragon: Izzy to [[spoiler:Matthew]]. As The Queen she also plays DragonInChief to Chris.
* FemmeFatale: Izzy is an archetypical one. She even wears black leather.
* FinalBoss: Of Season Seven.
* ForTheEvulz: The only reason [[spoiler:Matthew]] and Izzy do all the terrible things they do is that it gets them high, essentially.
* GodSaveUsFromTheQueen: The Queen is easily the most evil member of the group.
* HarmfulToMinors: Izzy does not seem to like children; she shot one at one of her previous robberies, shot a father in front of his daughter in the robbery the episode focuses on, [[spoiler:and psychologically screws with poor little Henry [=LaMontagne=]]].
* IneffectualSympatheticVillain: All things considered, the Strattons are kind of pathetic, and their caring for each other makes it difficult to properly hate them.
* ItsAllAboutMe: [[spoiler:Matthew]], whose entire motivation is that he was kicked out of the Marines for being a jackass and feels like the world owes him somehow.
* LackOfEmpathy: Izzy; it's implied all the empathy was beaten, or possibly even molested, out of her by her grandfather. [[spoiler:Matthew]] too, with no known FreudianExcuse.
* MalevolentMaskedMen: And, as Izzy would probably be quick to remind you, one woman.
* MauveShirt: [[spoiler:Oliver, who dies less than halfway into the first episode of the two-parter]].
* MoralityPet: The Stratton brothers to each other.
* OutlawCouple: [[spoiler:Matthew]] and Izzy
* ShellShockedVeteran: [[spoiler:Matthew]]
* TheSociopath: [[spoiler:Matthew]], who does and orders others to do terrible things while smugly grinning all the while. Izzy has shades of this, too; her favorite method of killing people is shooting them in the stomach, as that's the slowest and most painful place to bleed out from. In-show, Izzy is one of the few characters to actually be profiled as a straight-up psychopath, possessing no empathy, extreme rage, and poor impulse control, beneath a facade of intelligence and charm.
* SociopathicSoldier: Izzy and [[spoiler:Matthew]] are both disgraced ex-military.
* ThemeNaming: They're the Face Cards: Chris the King, Izzy the Queen, and Oliver the Jack, [[spoiler:plus mastermind Matthew, who doesn't take part in the robberies]].
* WoundedGazelleGambit: Matthew pretends to be a hostage.
* YouHaveOutlivedYourUsefulness: [[spoiler:Izzy does this to Chris. It's not entirely clear whether this killed him, but she shot him non-fatally in the chest and then abandoned him where he'd have no medical care, so it seems likely]].

!! The Replicator/[[spoiler:John Curtis]] (Creator/MarkHamill)

The ArcVillain of Season 8, the Replicator stalks the [=BAU=] team throughout the entire season, killing victims using M.O.s copied from the various [=UnSubs=] encountered by the [=BAU=] during the season.

* ArchEnemy: Sees himself as one for the entire BAU.
* ArcVillain: Of Season 8. More prominently than the Reaper or Ian Doyle, as he's introduced in the first episode of the season and lasts right up until the final episode.
* BigBad: Of Season Eight
* {{Catchphrase}}: "Zugzwang."
* TheChessmaster: Has a chess theme going on with his love of the word "Zugzwang"; manipulated the Unsub of Carbon Copy to kill and implicate himself as the Replicator to throw the BAU off his trail.
* DisproportionateRetribution: Is basically having a fit at [[spoiler:his demotion.]]
* EvilGenius: He's described as a genius in multiple fields, including computer hacking and biochemistry. His [[spoiler: FBI employment]] dossier lists him as having an I.Q. of 178, compared to Reid's stated I.Q. of 187.
* FallenHero: [[spoiler:Was an extremely skilled and successful FBI agent (Garcia describes him as a rockstar), but then mishandled the Amerithrax case. Strauss managed to pin the blame on him (and Alex Blake), saving herself. Strauss was fine, Blake recovered, but Curtis was [[ReassignedToAntarctica transferred to Kansas.]] His career never fully recovered, and now he wants revenge.]]
* FinalBoss: Of Season 8.
* HiddenInPlainSight: In the Season 8 finale, he hides from a massive FBI task force sent to capture him by ''standing around pretending to be an anonymous member of the task force''. This occurs after the FBI already know his identity and appearance. It works because it's night, he knows how to blend in, and the FBI expect him to be barricaded in his compound and not standing around right in their midst.
* HoistByHisOwnPetard: He tries to kill the BAU team by trapping them with him after playing with them for a year, but in the end Rossi manages to trick him and leaves him trapped in his own trap.
* IntelligenceEqualsIsolation: Blake describes him as having been brilliant but socially isolated [[spoiler: during the time the two of them served together in the same FBI unit]].
* JackTheRipoff: His MO is to kill his victims in the exact same way as [=UnSubs=] the BAU dealt with earlier, copying specifically the victims in Season Eight as well as an unnamed serial killer in Seattle that was active before the events of "The Silencer".
* KarmicDeath: Tries a TakingYouWithMe on Rossi, but is OutGambitted via ChekhovsGun from the late Strauss and left to die alone.
--> [[spoiler: '''Rossi:''' [[IronicEcho Zugzwang.]]]]
* TheManBehindTheMan: The BAU originally thought Donnie Bidwell was the Replicator, at least until Bidwell was DrivenToSuicide.
* ManipulativeBastard: Manipulates both the BAU and Bidwell extremely well.
* {{Revenge}}: [[spoiler:Mostly on Strauss]].
* ShoutOut: He likes using Adam Worth as his alias, who as Reid points out, was the inspiration for [[Literature/SherlockHolmes Moriarty]]
* WhosLaughingNow: But only for [[spoiler:Strauss and Blake.]]

[[folder:Other Notable [=UnSubs=]]]

!!Mark Gregory (Andy Comeau)
%%* CaptiveDate
* FreudianExcuse: [[spoiler: His mother cheated on his father, and his father was too spineless to call her out on it.]]
* MakingASplash: He kills his victims by drowning.
* MasterOfDisguise: He's the only [=UnSub=] whose identity is know by the BAU in advance, but the local authorities need help catching them because he keeps changing his appearance.
* NoCelebritiesWereHarmed : Well not really a ''celebrity'', but Gregory was clearly based on infamously successful real life serial killer Ted Bundy. Their MO is practically identical, charming and convincing attractive young women into following them to secluded areas and then killing them. Gregory's use of the " cripple carrying groceries " disguise was directly lifted from Bundy. Also, much like Bundy, he devolves from using elaborate plans to plain snatching women, which made it possible to catch him (only whereas Gregory devolves after a couple of days, Bundy, scarily, took ''years'' to devolve).
%%* SerialKiller
* VillainOfTheWeek: Of "Charm and Harm"
* VillainousBreakdown: He starts out luring his victims with a ruse, staging romantic dinners with them, then torturing and drowning them, but eventually devolves to simply abducting and killing them immediately as the BAU closes in on him.
* WickedCultured: As seen when he discusses the qualities of fine Scotch whiskey over a gourmet steak dinner with one of his victims.

!!Paul and John "Johnny" Mulford (Jim Parrack and Jake Richardson)
* AlasPoorVillain: The conclusion of "Open Season" sees [[spoiler: Paul getting shot fatally for refusing to let the target who wounded his brother go and mumbling Johnny's name as he dies; Johnny, who has Gideon staying with him and gently trying to keep him calm, hears the gunshots and breaks down crying just before dying himself.]]
* TheArcher: The compound bow is their WeaponOfChoice - requires precision for an efficient kill.
* BewareTheQuietOnes: A hunting supply shopkeeper casually reflects that their late uncle, who taught them to hunt humans, was "a quiet man". She also claims that Johnny is a ShrinkingViolet, and that she thought it was kind of endearing.
* DeathByIrony[=/=]HoistByHisOwnPetard: Paul's the better hunter of the two of them and insists that they shouldn't go for easy kills either of two occasions during the episode that they have their victims cornered. They end up keeping them alive long enough for their main target to turn the tables on them and hunt them back.
* EvenEvilHasLovedOnes: Profiled as having an "us against them" mentality, and were practically each other's only company growing up. They're obviously close, and behavior by each of them when the other is in danger is what gets them caught.
* TheFamilyThatSlaysTogether: They were raised by and picked up human-hunting from their uncle, and kept on as SiblingsInCrime after he passed away.
* GigglingVillain: Mostly Johnny. Murder clearly tickles them pink.
* HuntingTheMostDangerousGame: Their modus operandi.
* IronicEcho: "He's all I have." First said to the B.A.U. by the father of one of their victims; later said [[spoiler: by Johnny while he's begging the team not to kill his brother.]]
* PleaseDontLeaveMe: [[spoiler: A wounded Johnny clings to Paul and tells him "no" before Paul leaves him by a campfire to try finishing off their target regardless.]]
* SuicideByCop: [[spoiler: The team surround Paul with their guns pointed when he finally has Bobbi cornered, ordering him to drop his bow. He pauses for just a moment - and then tries to take the shot anyway. Since they would've opened fire on him even if he'd hit her, it comes off as this with a side of TakingYouWithMe.]]
* VillainOfTheWeek: Of "Open Season".

!!Charles Holcombe (Tahmus Rounds)
* DeathCourse: The way he has modified the meatpacking plant his family owned. His maze includes such disturbing features as gas vents and vicious dogs to keep victims moving, identical rooms and dead ends to keep victims confused, a room with the floor covered with broken glass, and a room with parts of his previous victims suspended by chains from the ceiling.
* EvilCounterpart: To Detective [=McGee=]. Both suffer from obsessive-compulsive disorder, both have lost their own father and both are focused on street people.
* TheFaceless: His face is always hidden behind a surgical mask, and isn't shown until [[spoiler:after the police gun him down to stop him from killing his latest victim.]]
* HopeSpot / ILied: He offered his victims a way out, only to [[spoiler: knock them down with gas if they managed to reach the exit]].
* {{Jerkass}}: Is profiled as one and it helps turn his OnlyFriend against him.
* JudgeJuryAndExecutioner
-->'''Maggie:''' I don't have any diseases. I just went to the clinic. I'm clean.
-->'''Charles:''' You don't even know the meaning of the word. You've been judged and sentenced to death.
* KillThePoor: His victims are homeless people, prostitutes and junkies.
* KnightTemplar: Believes he's doing the world a favor by eliminating "undesirables".
-->'''Charles:''' ''(as the cops bust into his lair)'' Just let me do my job!
%%* ManipulativeBastard
* MissingWhiteWomanSyndrome: Nobody seems to notice his kidnappings since nobody notices his victims in the first place. Lampshaded by Hotch, as these exchanges illustrate:
-->'''Hotch''': What do you think happened to them, Captain?
-->'''Capt. Wright''': I told you, I don't think anything happened to them.
-->'''Hotch''': Oh, that's right. You think they all got houses and jobs.

-->'''Hotch''': What if they were cheerleaders?
-->'''Capt. Wright''': Excuse me?
-->'''Hotch''': Or teachers, or mothers? How did you put it, "Can bums even be missing?" Well, sir, they can. They can be hurt, they can be scared, and they can be killed.
* SerialKiller: of the homeless
* ShoutOut: In the opening scene, he's whistling "[[Theatre/SweeneyToddTheDemonBarberOfFleetStreet Johanna]]". Also, there are a lot of references to the ''Franchise/{{Saw}}'' saga.
* SmugSnake
-->'''Charles:''' But you will beg, whore. They all do.
%%* SuperOCD
* TortureTechnician: Via his maze
* VeryLooselyBasedOnATrueStory: Inspired by H. H. Holmes, a serial killer in 1890s Chicago who built a fake hotel riddled with booby traps to torture and kill unwitting guests and staff.
* VillainOfTheWeek: Of "Legacy".

!!Stanley Howard (Michael O'Keefe)
* AbusiveParents: His mother.
%%* AffablyEvil
* AwesomeByAnalysis: Believe it or not, he manages to profile ''Hotch'' the first time he sees him. Being a professional psychologist probably helped.
--> '''Stanley Howard:''' I think your greatest fear is that [[SamaritanSyndrome you can't save everyone]].
* CatchPhrase: "Is it worse than you thought?"
%%* ControlFreak
* EvenBadMenLoveTheirMamas: Subverted. He didn't even attend his mother's funeral. He had his own motivations, however.
* {{Foreshadowing}}: He noticed Hotch's SamaritanSyndrome, which became prominent during the Reaper story arc.
* ForScience: How he tries to rationalize his murders when [[spoiler: facing Hotch]].

* SerialKiller: of his patients, via their fears.
* VillainOfTheWeek: Of "Scared to Death".

!! Floyd Feylinn Ferell (Jamie Kennedy)
* BornLucky: He is the beneficiary of lucky breaks so implausibly often that even Reid wonders if he might have someone downstairs looking out for him.
* CuteAndPsycho: Part of his background. He was institutionalized when he was only seven years old, after taking a bite out of ''his nine-month-old sister.''
* DemonicPossession: Part of his delusion is that he believes he is possessed by a flesh-eating demon.
* EatTheRich: Started out by targeting prostitutes and junkies, but moved up to more well-off women because his first targets "tasted funny."
* EatsBabies: His first victim was his infant sister.
* EvilChef: He cooks people.
* FatBastard: As a teenager at the mental hospital, due to the harsh side effects of the antipsychotics he was on.
* ImAHumanitarian: His homemade cookbook includes recipes with such charming names as "Kobe Girl Steak" and "Skewered She".
* NumberOfTheBeast: Each of his three names starts with 'F', the sixth letter of the alphabet. Additionally, his names have an average of six letters each.
* ReligionOfEvil: His belief system is based on Satanism, but it's all part of his delusion. The BAU classify Ferell as an "Adaptive Satanist", a serial killer who rationalizes his murderous urges by blaming them on outside forces. To quote Rossi, "He doesn't kill because he believes in Satan, he believes in Satan because he kills."
* TheSecretOfLongPorkPies: His day job is running a BBQ restaurant, and considering the "secret ingredient" in the chili he served to the search party, it's a good bet that some of his customers got a lot more than they paid for...
* SerialKiller: Of women
* SlasherSmile: Gives one to [[spoiler:Father Marks when he reveals what kind of meat was in the chili he served to the search party.]]
* SoundtrackDissonance: His favorite song is "Sittin' in the Dark" by Louie Armstrong.
* TastesLikeChicken: [[spoiler:Except the "Chick" part of his "Chick 'n' Chili" has nothing to do with chicken...]]
* TooSpicyForYogSothoth: "The skinny ones take drugs. They taste funny."
* VillainOfTheWeek: Of "Lucky".
* WhamLine: When Father Marks tells him, "God is in all of us," Floyd responds, [[spoiler: "So is Tracey Lambert."]]

* AntiHero[=/=]AntiVillain: The episode even ended with a quote from FrankMiller.
%%* BadassLongcoat
* CreatorBreakdown: In-universe.
* DarkIsNotEvil: Played with. Sure, True Night is a murderer, but [[spoiler:his victims were worse criminals than him]].
%%* DarknessEqualsDeath
* DualWielding: Is seen dual wielding katanas, but he's actually dual wielding machetes.
* IronicEcho: "You're not gonna wanna miss this".
* KickTheDog: He attacked a man who had nothing to do with [[spoiler: the gang he was targeting]]. Luckily, the man didn't die.
* NoKillLikeOverkill: His victims were hacked to bits. In particular, [[spoiler: Glen Hill]] was gutted, dismembered and then beheaded.
* PowerBornOfMadness: His unexpected strength and extremely high tolerance to pain come from a severe psychotic break.
* RoaringRampageOfRevenge: What motivates his killings.
* SympatheticMurderer: All his victims were gang criminals who [[spoiler:had raped and killed his pregnant girlfriend and gutted him]].
* VigilanteMan: Goes after gang members.
* VillainOfTheWeek: Of "True Night".
* WoobieDestroyerOfWorlds: Even the team feel sorry for him.

!! Jeremy Andrus (Christopher Allen Nelson)
%%* BeardOfEvil
%%* BlondesAreEvil
* BreakTheHaughty: His preferred victims are women with influential, high-paying jobs, but since he's a [[HeManWomanHater misogynist]] who [[StayInTheKitchen expects women to be submissive]], he's the only one who sees these women as "haughty", and is trying to break them for that reason. Otherwise, no evidence is given that any of his victims were any more stuck up than their male counterparts. [[spoiler: The only one who comes close is Agent Morris, who is egotistical and trying to use his case to gain personal fame, but he gets arrested before he can follow through on her.]]
* CreepyCrossdresser: Acts out "rehearsal fantasies", wherein he wears the clothes of his victims while listening to recordings of their torture and pleasuring himself, so he can relive their pain while preparing to take his next victim.
* ADateWithRosiePalms: During his rehearsal fantasies.
* ElectricTorture: The method he eventually chose when he started killing.
* EvilCounterpart: To Agent Morris. Both of them are using his crimes to make names for themselves and become famous.
%%* AGodAmI
* HeManWomanHater: Is motivated by his hatred of women.
* {{Narcissist}}: He intentionally stopped paying the rent on his storage unit so the authorities would find his writings because he not only wanted them to know he existed (he'd been killing for six years straight without anyone noticing), he wanted them to be able to chart his entire killing spree from beginning to end. The attention his case attracts feeds his ego and allows him to relive his murders in a new way.
* SerialKiller: of women.
%%* TheSociopath
* TortureTechnician: Wrote extensively about the various torture methods he fantasized about using.
%%* UnsexySadist
* VillainOfTheWeek: Of "Limelight".

!! Owen Savage (Cody Kasch)
* [[AbusiveParents Abusive Father]]: His father resented him since he had had to leave the Marines to take care of his son.
* AdultsAreUseless: Given everything that he went through in his life, Owen was basically a time bomb. As Reid pointed out, if the police or school authorities had actually taken advantage of the many chance they had to intervene, he probably wouldn't have gone on his spree. The cop he angrily yells this to tries to disagree but he clearly knows Reid is right.
* AmbiguousDisorder: Reid realises Owen has a undiagnosed learning disabiltiy but is otherwise pretty smart while looking through his schoolwork and grades.
* ADateWithRosiePalms: Three of his victims were the guys who had filmed him when he masturbated in the shower room as initiation and posted it on the schools social network from which it presumably reached the Internet.
* BullyHunter
* KickTheDog: When he stabbed Ike Stratman, though it was to avoid being discovered, and he clearly showed remorse.
* MissingMom: She died in a drunk driving accident.
* MisunderstoodLonerWithAHeartOfGold: Before the killings started, at least.
* MonsterSobStory: His life pretty much sucked.
* MoralityPet: Has one in Jordan.
* NoKillLikeOverkill: His father and Kyle Borden ([[AssholeVictim the guy who had taken advantage of Jordan]], Owen's girlfriend with slower learning abilities) were shot in the face at a point-blank range. The team actually profile this when he shoots his already dead father in the face, ignoring the other cop who is still alive.
* NotSoDifferent: Reid identifies with him because they both went through hell at high school.
* SuicideByCop: [[spoiler:Attempted. Reid managed to stop him.]]
* SympatheticMurderer: A bullied, abused kid.
* VillainOfTheWeek: Of "Elephant's Memory".
%%* WhosLaughingNow

!! Henry Grace (Creator/JasonAlexander)
* AwesomeByAnalysis: Deliberately plays on this, hoping that the team will figure out his pattern without him giving too obvious hints or clues, so that they will walk into his trap and, further, so that he can get OffOnATechnicality when Rossi doesn't have any evidence that doesn't sound like a BatDeduction.
* BatmanGambit: Draws attention to his own crimes and goads Rossi into staying behind to interview him in order to trick the rest of the team into walking into his DeathTrap, while only giving very vague clues to this end so that they have to get themselves killed by their own work and he can reasonably plead coincidence and lack of evidence. [[spoiler: He's OutGambitted by Rossi who realises what's going on and pulls one of his own to get an EngineeredPublicConfession.]]
* BreakingSpeech: A whole episode of these, mostly directed at either Rossi or Reid.
%%* CriminalMindGames
* DirtyCoward: Always attacks his victims from behind, both because he's a pretty small guy and because women intimidate him. Rossi calls him out on it after [[spoiler: he attacks him too; Rossi ''knew'' he would do it and ''knew'' he would wait for Rossi's back to be turned.]]
* DisproportionateRetribution: Murders several women just because they reminded him of the fiancee` who dumped him years ago.[[spoiler: And plans on killing the entire team to get back at Rossi... for exposing his brother as a SerialKiller.]]
%%* EngineeredPublicConfession
%%* EvilGenius
* ExactWords: Kidnaps a teacher and four students, and then tells the BAU that in 9 hours 5 people will be dead. [[spoiler:The exact wording is used twice. First when he reveals that the traps will kill someone every 2 hours (except not), pointing out that he didn't say they'd ''all'' die at once at the ninth hour mark. The second is when it's revealed the 5 man BAU team are the targets, as he never said the 5 hostages would die]]
%%* FauxAffablyEvil
* FirstNameBasis: With Rossi.
* TheFettered:[[spoiler: The team realises he didn't kill the teacher and kids, even when it looked like he actually started to, because that would have messed up his "perfect" murder pattern.]]
* InsufferableGenius: He's clearly smart and incredibly full of himself. But he isn't quite as smart as he thinks.
* InTheBlood: Firmly believes this. Rossi calls it "junk science" and thinks he's just looking for excuses.
* ItsPersonal: Blames Rossi for ruining his life...[[InsaneTrollLogic for capturing his Serial Killer older brother.]]
* LonersAreFreaks: Mentioned as being a non-teaching professor, to the point where nobody on campus seems to know who he is. Justified in that everyone who he ''had'' been on normal terms with didn't want to know him after his brother was exposed as a homicidal maniac.
* OffOnATechnicality:[[spoiler: Subverted. When he realises he has lost he tries to pull this off, since he disposed of all his bodies with sulphuric acid and, despite drawing attention to his own killings, the [=BAU=] had to simply guesstimate who they thought he might have killed by themselves, while the family he kidnapped never saw him and the team only saved them thanks to highly esoteric and very well hidden clues he left, that border on a BatDeduction enough that he could plead lack of evidence. But circumstantial evidence along with his EngineeredPublicConfession are enough to put him away.]]

%%* SerialKiller
* ShutUpHannibal: Rossi gives him a nasty one resulting in a VillainousBreakdown.
%%* SmugSnake
* SympatheticMurderer: He would be if not such a bastard.

* GoingPostal: [[spoiler: Subverted. It looks like he's about to when his much-younger supervisor asks him about some overdue paperwork, but he decides against it when the supervisor says he actually likes him as a person, and is just worried that the higher-ups will look for any excuse to fire him due to cutbacks.]]

* SympatheticMurderer: [[spoiler:He watched his youngest daughter die while he was fixing a flat tire, fell into depression and became a paranoid schizophrenic, believing that everyone hated him and blamed him for his daughter's death. Early on, he killed his wife and daughters in their sleep and hallucinated that they were still there and were upset with him.]]

* BrainsAndBondage: She's a learned woman and at least one of her victims had been consensually bonded before being poisoned.
%%* BrokenBird
* DaddysGirl: Averted. Her father is an abusive and violent man, who nevertheless tries to use this trope to get what he wants from her. [[spoiler: He fails.]]
* DatingCatwoman / FoeYay: Her interaction with Hotch implies she sees herself this way. Her reaction to Trent claiming that the FBI was in the pocket of the Execs she was exposing with her murders made her feel like Hotch was no better than the people she was trying to hurt. [[spoiler: though her mind changed when Hotch stayed with her when she died.]]
* {{Dominatrix}}: Some of her clients wanted her to play this role.
%%* DrivenToSuicide
* DumbBlonde: Averted. She's interested in foreign literature, can speak and read French and is also very cunning.
* EatTheRich: Only hunts {{Corrupt Corporate Executive}}s.
* FirstNameBasis: Assumes one with Hotch, openly calling him Aaron. Much to the surprise of the team.
%%* FreudianExcuse

* HighClassCallGirl: Though not for money. She wanted to punish the men on her list.

!! Adam Jackson (Jackson Rathbone)
* {{Asshole Victim}}s: His preferred victims were jerkasses who reminded him of his stepfather. At least one cheated on his girlfriend with no remorse and they all tended to treat women badly. One even shoved him to the ground when Adam tried to stand up for a girl he was bothering.
* BewareTheNiceOnes: Adam is, on his own, a pretty nice and likable guy. But when he snaps, he goes into full berserker rage.
* FreudianExcuse: [[spoiler:Was abused physically and sexually by his stepfather when he was a boy. The trauma of the abuse spawned a SplitPersonality who only comes out when Adam is harassed or bullied by dominant men. Unfortunately for him, he has no clue about any of this.]]

* EnfanteTerrible: He's nine years old.
* HairTriggerTemper: Has an absolutely explosive temper, at one point becoming enraged over his inability to open a bag of chips.
* KickTheDog: Murdered his puppy.
* LackOfEmpathy: Danny has far more attachment to his models than he does to his dog, his brother, or even his parents. He's also incapable of real emotion in general, though he can fake it.
* ManipulativeBastard: Fooled his parents into believing he was sorry as a way to avoid punishment.
* TheResenter: Resented Kyle for being in the way.

!! Samantha Malcolm, the Dollmaker (Jennifer Hasty)
* AbusiveParents: [[spoiler:Her father used to molest her as a child. To keep her from telling what he had done, he coached her on what to say, making her get electroshock therapy if she ever got the story wrong, which permanently warped her mind.]]
* AccidentalMurder: She doesn't want her victims to die. Instead, she does her best to keep them alive, even if the state of paralysis in which they are inevitably leads to their death.
* AndIMustScream: She uses injections to paralyze her victims so she can dress them up and have tea parties with them.
* BlondeBrunetteRedHead / TokenMinority: Her dolls are a blonde, a red head, and an African-American girl.

* SerialKiller: Not that she's aware of it.
* SympatheticMurderer: Without {{Asshole Victim}}s.
* VillainOfTheWeek: Of "The Uncanny valley".
* [[ManChild Woman Child]]: The way she acts and moves puts you in the mind of a five year old. She even has tea parties with her "dolls". Also, when one of her victims dies, she leaves the body in places crowded by children, like parks or carnivals.

%%* EvilOldFolks
* FauxAffablyEvil: They often pretend to be polite and friendly while actually being cold-hearted monsters.
* GenericDoomsdayVillain: Their reasons for doing what they do are never explored, unlike with most [=UnSubs=]. Semi-justified, though: this episode focuses more on the victims and their families.
* GuiltRiddenAccomplice: Roger seems to show slight traits of this, but the interpretation is left open and is ''very'' debatable.

* AbandonedMine: His hideout, which gives him a secluded place to imprison his victims as well as shelter during the winter.
* AnAxeToGrind: Used one to mark trees near his dump sites.
* BeardOfEvil: Though he shaves it off [[spoiler: after he successfully escapes.]]
* EvilCripple: Has a degenerative joint disease, which gives him a bad limp.
* FatBastard: Though it's more accurately "Stocky Bastard", since aside from his limp, he's still fit enough to easily navigate the wooded terrain.
* TheHermit: Abandoned civilization for the woods along the Appalachian Trail to make it easier for him to hunt children (the Trail is a popular family camping destination) and harder for law enforcement to find him (since he knows the terrain better than they do, and nobody expects a child abductor to be operating out in the wilderness).
* KarmaHoudini: One of the only [=UnSubs=] to elude the BAU [[spoiler:and the only unsub to get away completely scot-free.]] However, he has a degenerative disease that is slowly and painfully crippling him, and is no longer able to get the pain medication he needs, so he will likely die a very unpleasant death in the mountains.
