[[folder:The Team]]
!!Dr. Lee Rosen
->'''Played by:''' Creator/DavidStrathairn\\

A neurologist and psychologist who specialises in the study of "alphas". He leads the DOD-sponsored team of Alphas, but is slowly becoming disillusioned as the team's mandate shifts from finding and helping Alphas in trouble to fighting dangerous Alphas and locking them up. He started investigating the Alpha phenomenon after [[spoiler:discovering that his daughter was one]].
* AmbiguouslyJewish
* BadassNormal
** BadassBeard: In the Pilot and in season 2.
** BadassBoast: In "Memory Serves" see GoodIsNotSoft below.
* BewareTheNiceOnes: He's calm, diplomatic and level-headed, probably one of the nicest guys in the show. But push him hard enough ([[PapaWolf or threaten his daughter]]) and he'll ''[[RoaringRampageOfRevenge destroy everything you love]]'' and [[MindRape shatter your mind in a million pieces with ruthless skill]]. Parrish learned this the hard way.
** Similarly, don't taunt him over the fact that [[spoiler: Danni was TheMole, and was killed by Parrish]]. Just ask Scipio.
** BewareTheQuietOnes: He almost never raised his tone across the entire series, but let it be known that Rosen's affable talks can sound just as threatening as a wrathful scream if he wants to.
* TheChessmaster: While clearly not to Parrish's level, he's been doing an effort to catch up with him in this regard. [[spoiler: His little gambit with Hicks near the end of season two shows how dangerous he can be.]]
* CoolOldGuy
* CosmicPlaything: Every effort he makes to improve human-Alpha relations somehow manages to backfire horribly and make the situation worse than it was before.
* TheDeterminator: Nothing will stop this man's quest to take down Red Flag.
* ForScience: Occasionally displays this viewpoint. For example, when wishing to determine whether Nina would be able to recover a repressed memory, he describes Kat as "the perfect test subject." However, he never goes so far as to ignore a person's free will or humanity.
* GoodIsNotSoft: In "If Memory Serves".
-->'''Rosen:''' Yes, Senator. You are right. My team is dangerous ... and so am I.\\
'''Rosen:''' (to Cameron about Stanton Parrish) He's not a sociopath. He cares quite deeply about [Mitchell] and he cares quite deeply about Dani. And this humanity of his makes him vulnerable. That's his weakness ... and we are going to use it against him.
* GuileHero: [[TheShrink Comes with the territory.]]
* TheHeart: Without him, the team can barely function. When absent for eight months between seasons, Nina has reverted to pushing everyone on a whim, Hicks can't hit the broad side of a barn, Gary gets sent to Building 7 when his new NSA co-workers refuse to accommodate him (resulting in a freak-out that injures two of them), and Rachel won't even leave her room because she can't control her senses. The only one who isn't overtly suffering is Bill, and that's because he's busy trying (and slowly but surely failing) to fill the void left by Rosen. When Rosen comes back, he pretty quickly gets everyone back to relative normalcy.
* HeroicBSOD: When [[spoiler: he wields a gun for the first time to kill an Alpha]], his reaction is a textbook example of this [[spoiler: He also almost breaks down when he discovers his daughter is a Mole for Parish.]]
** [[spoiler: And again when Danielle meets her painful end.]]
* HeWhoFightsMonsters: Rosen seems to be showing shades of this in the later episodes in his desire to stop Parrish.
** [[spoiler: Ultimately subverted in the second season finale.]]
* ISeeDeadPeople: After he gets shot in "Need to Know", he spends the entirety of the season 2 finale [[spoiler: seeing Dani, hearing her talking him down and willing him to continue his pursuit of Stanton Parrish]].
* KilledOffForReal: Er...maybe. This is the logical assumption given that he was in range of Parish's device when it went off in the season 2 finale, but it hasn't been confirmed yet.
* MyGreatestFailure: Feels this way about [[spoiler:Marcus]].
** [[spoiler: His estrangement from his daughter, Dani. Even more so after their reconciliation is cut tragically short]].
* NiceJobBreakingItHero: It probably wasn't his plan to [[spoiler:kick the psychotic Scipio's powers UpToEleven and burn down an entire forest, secret Alpha commune included]].
* PapaWolf: Often comes across as very protective of Nina, Rachel and Gary, as well as his daughter Dani.
** Illustrated when Hicks mentions he's dating his daughter. Rosen says he is cool with it, as long as he doesn't break her heart, in which case Rosen will fire Hicks. Both nervously laugh it up a bit, but Rosen's inability to keep a smile demonstrates that [[OhCrap he is serious about the threat]].
** Stanton Parrish had a plan to recruit Rosen. He may have even succeeded. But he made the mistake of threatening Rosen's daughter, which results in Parrish getting tossed in a cell when he thought Rosen would keep his word and let him leave.
** [[spoiler: Parrish killing Dani]] made him a bit...unhinged, to the point where had no problem using an innocent Alpha as bait in his quest for revenge, something that directly contradicts his previous characterization.
* ParentalSubstitute: To Nina.
* ReluctantWarrior: He treats violence as a last resort but will not let this stop him from saving lives.
* RevengeBeforeReason: [[spoiler: In Series 2, after Stanton Parrish lets Dani die after [[YouHaveOutlivedYourUsefulness she's no longer useful to him]].]]
--> '''Hicks''': [[spoiler: You know that if Clay catches Parrish, he'll put him in prison? He doesn't ''deserve'' to go to prison!]]
--> '''Rosen''': [[spoiler: *''TranquilFury''* No. No, he ''doesn't.'' [[LetsGetDangerous I'm going to need your help.]]]]
* RoaringRampageOfRevenge: Rosen goes on one after [[spoiler:Dani's death]], and he brings Cam along for the ride.
* ScienceHero: Rosen is consistently seen using medication and drugs to counteract or enhance various Alpha abilities. Even Cornell Scipio visibly cringed when he saw Rosen with a syringe [[spoiler: during "Need to Know."]]
* SesquipedalianLoquaciousness: Generally averted, but he gets one in "When Push Comes To Shove":
-->'''Rosen:''' "Your neurons must myelinate at an astounding rate."\\
'''Kat:''' *Confused look*\\
'''Rosen:''' "Sorry, it's commonly called muscle memory."
* ShadowArchetype: To Stanton Parrish, who is also a leader of a group of Alphas seeking to change the world. The key difference is that Rosen doesn't want bloodshed on his hands and still believes there can be peace.
* TheShrink: Of the third variety.
* SilverFox
* StepfordSmiler: Puts up a happy façade very often to hide how he feels.
* TeamDad
* TheTeamNormal: Though he makes it clear that he does not consider himself to be apart from them because of it.
* TortureTechnician: Rosen can be a utter master of psychological (no surprise, since he's a shrink) and physical torture, if pushed hard enough. Definitely ''not'' ExaltedTorturer, because most of the characters consider this to be a KickTheDog moment at least and a MoralEventHorizon at worst.
* TheUnfettered: [[spoiler:In his quest for vengeance on Parrish after Dani's death]]
* WellIntentionedExtremist: Has his moments of this.
* WideEyedIdealist: He honestly believes Alphas and regular humans can learn to co-exist peacefully.

!!Nina Theroux
->'''Played by:''' Laura Mennell\\

A young woman who used her Alpha ability -- [[CharmPerson "pushing" people into doing what she wants]] -- for petty personal gain, until her activities brought her to Rosen's attention. She's been on the team for longer than anyone else, and serves as Rosen's [[NumberTwo second]]. Has oodles of {{UST}} with Hicks.
* TheAtoner: She thought she accidentally killed her boyfriend with her ability. Also, [[spoiler: she accidentally drove her ''father'' to suicide during her childhood since she commanded him to ''never'' leave, which left him unable to leave their house]].
* BelligerentSexualTension: With Cameron, as of season two.
* BlackBraAndPanties: She's revealed to be wearing them after undressing to have sex with Cameron.
* CharmPerson
* CompellingVoice
* DarkAndTroubledPast: [[spoiler:She tried to save her parents' failing marriage by pushing her father to stay. She pushed him so often that he could barely think for himself, and he eventually committed suicide.]]
* DrivenToSuicide: Got saved by Hicks just in time.
* [[HeroWithAnFInGood Heroine With An F In Good]]
* MoralityChain: Dr. Rosen is definitely one for her.
** [[spoiler: She goes off the rails and back to her old habits, when he is institutionalized between Series 1 and 2]].
** Curiously, she tries to be this for [[InvertedTrope Rosen]] a few times as well (Mostly on his HeWhoFightsMonsters routine)
* MoralityPet: As much as she would deny it, she has a soft spot for Gary.
* MyGodWhatHaveIDone: When she realizes that she [[spoiler: pushed her childhood friend into leaving his family behind and being with her.]] She thought she had a genuine relationship with him and was apparently unaware that she was controlling him the whole time.
* NumberTwo
* PsychicStatic: Her ability functions as this for [[spoiler: Hicks in "The Devil Will Drag You Under", preventing Parrish's telepath from discovering that he's undercover.]]
* TeamMom
** She also comes across as a CoolBigSis to Rachel.
* TookALevelInJerkass: Season 2 but she got better in later episodes.
* WoobieDestroyerOfWorlds: [[spoiler: She causes Hicks to shoot John and makes Rachel kiss her, but once her true backstory is laid bare, it's hard not to feel for her and understand why she is the way she is.]]

!!Bill Harken
->'''Played by:''' Malik Yoba\\

A happily-married FBI agent with SuperStrength. Bill was suspended from the Bureau after getting angry with a colleague and accidentally shoving him through a solid wall; he only planned on staying with Rosen's team until his suspension was over. [[spoiler:He's since decided to stay on the team, even though the Bureau offered to reinstate him.]]
* BadassBeard
* CharacterDevelopment: He respects Gary more and becomes more protective of him after their episode together. The two refer to each other as partners from then onwards.
* DeadpanSnarker
* HappilyMarried
* HourOfPower: Can only have his power activated for 5 minutes.
* HugeGuyTinyGirl: Him and his wife.
* LightningBruiser: Has martial arts training, which he does use in concert with his SuperStrength. As a result, he can keep up with [[SuperReflexes Hicks]] in a down-and-out brawl well enough to win. In this case, notably, his SuperSpeed didn't really come into play.
* MadeOfIron: He can stand still and take a beating from three armed men, one of whom is ''tasing'' him continuously, without moving. Partially explained by his ability to control his adrenaline rushes, as adrenaline is known to make it easier to ignore pain. The aches, pains, and injuries he must logically have collected don't seem to affect him later, either.
* NumberTwo: In Season 2 he [[spoiler:takes over this role while Nina is off the team and recovering; Rosen still goes to him to spearhead Black Ops type stuff, like the search to root out the mole.]]
* OnlySaneEmployee: He's the only member of the team with a law enforcement background, which brings him into conflict with his less experienced partners and his idealistic boss.
* PapaWolf: Towards Kat when he learns about her memory loss. She calls him on it pretty quickly.
* PetTheDog: Though he was as ambivalent towards Gary as everyone else on the team, Bill always laughs at Gary's antics where others would fume in early episodes (quite possibly the result of the actor not being able to keep a straight face). This provides some early indications of his later friendship with Gary following "Bill and Gary's Excellent Adventure".
* ScaryBlackMan
* SuperheroesStaySingle: Averted.
* SuperSpeed: This mostly takes a backseat to his strength, but the same adrenaline boost that makes him strong lets him run like a track star. Demonstrated when he tries to chase an Alpha with hyper-speed, but fails when he can't control his momentum and slams into a trash bin.
* SuperStrength
* VitriolicBestBuds: Has become this with Gary. Type 2.
* TheWorfEffect: Suffers from it against Kat in the Alpha Fight Club. She uses fighting moves she picked up with her super muscle memory and [[CurbStompBattle utterly kicks his ass]], something several previous opponents failed to do. Even taking into account the fact that Bill was quite reluctant to fight her, we've seen the man stand up to beatings far in excess of what she doled out.
* WouldHitAGirl: An absolutely epic takedown of [[spoiler:Kimi Milard]] in "The Devil Will Drag You Under".
** Not to mention [[spoiler: [[SuperReflexes Trisha]]]] in "Alphaville".

!!Rachel Pirzad
->'''Played by:''' Azita Ghanizada\\

A very introverted young woman with SuperSenses, who was a CIA linguist before joining Rosen's team. She's under constant pressure from overbearing parents that want her to settle down rather, and the downside of her ability -- SensoryOverload -- makes things difficult in social situations.

* ArrangedMarriage: Her parents tried several times before the beginning of the show. Currently averted; see below.
* BlessedWithSuck: She arguably has the worst drawback of the entire team; at least, the most debilitating. She can't help but focus excessively on whatever she's doing, which means she sees how horribly disgusting every surface is, smells everything at greater intensity, and can barely kiss a guy without her sense of touch going haywire.
** CursedWithAwesome: When she gets her abilities dialed up by the power-amplifying photic stimulator, all those downsides are magnified even further... except she can suddenly get intimate without it overwhelming her. Not a bad exchange, all things considered.
* CantHaveSexEver: At least, until she can find a way to get past the sensory overload problem.
** She eventually reveals that she has had sex before, but had to be drunk to the point of numbness to deal with it. [[spoiler:She eventually manages to have sex with John. It's implied that this is because he's the first man she's met who she trusts enough to completely open herself up to the sensations of sex with, while knowing that it'll leave her utterly incapable of any kind of voluntary action]].
* DisabilitySuperpower: Her Alpha ability invokes this: She turns one sense way up by shutting the others almost completely off.
* TheEmpath: She can smell the chemical signatures of different emotions.
* HeelFaceDoorSlam: Not done to her, but by her. When [[spoiler: Nina]] tries to apologize to her, she doesn't want to hear it.
* LivingLieDetector: By looking for cues such as perspiration, pupil dilation, and heart rate.
* ParentalAbandonment: Thanks to the HatePlague guy, she yelled at her parents, who later kicked her out because of it.
** Though the premiere of Series 2 shows that they took her back in, since she regressed after [[spoiler: Dr Rosen was locked up]].
* PetTheDog: In a similar situation to Bill, she has a tendency to always crack a smile at Gary's antics.
* PowerIncontinence: Though she can dial up her senses at will, they also kick in automatically whenever she focuses on something (like eating or making out with a guy).
* SensoryOverload: Her sense of touch backfires spectacularly during intimate moments.
** But also averted; she is able to shrug off the effects of a SensoryOverload device by dialing up her up her sense of taste, thus dampening the visual and auditory overload the device induces.
* SuperSenses: She can turn up one sense at the cost of turning down all the others.

!!Gary Bell
->'''Played by:''' Ryan Cartwright\\

A high functioning autistic man with the ability to [[{{Technopath}} see and interact with the electromagnetic spectrum]]. Gary still lives with his mother and is very dependent on the team's help, but over the course of the first season he becomes more and more self-sufficient. He develops an odd friendship with Anna, one of the leaders of Red Flag, which prompts him to start thinking of the relationship between Alphas and humans.
* {{Adorkable}}: Can be this in his nicer and happy moments, such as when he gets the foot massage machine.
* CharacterDevelopment: He respects Bill more (and actually defers to him on occasion), and treats him more like a friend, after "Bill And Gary's Excellent Adventure". Also, throughout the first season he's trying to learn to become more self-sufficient and independent, as well as trying to be able to learn and do more things he normally would not, such as lying.
** In season 2, he takes it even further by moving out of his house and into the office. He's still surrounded by people, but is technically the only one who stays the night. [[spoiler:Part of the reason he did this, though, was to stop worrying his mother because of his screaming every morning as his mechanism to cope with Anna's death. It counts as character development because he is thinking of his mother's well-being instead of his own.]]
* {{Cloudcuckoolander}}
* DatingCatwoman: His friendship/budding relationship with Anna, a Red Flag leader. [[spoiler:Until she died.]]
* DisabilityImmunity: His autism makes him immune to numerous mind-based afflictions or abilities. Nina's CompellingVoice fails because his mind is too inflexible, a LivingLieDetector whose power works by reading micro-expressions is thrown off by Gary's constant fidgeting, an Alpha who uses infrasound to induce life-threatening hallucinations merely creates a helpful one for Gary, and Stanton Parrish's photic stimulator (which enhances Alpha abilities and induces seizures) has no apparent effect on him.
* DudeWheresMyRespect: After becoming an official government agent, he occasionally insists that people refer to him as "Agent Bell". As seen in the episode "Bill and Gary's Excellent Adventure", he's quite pleased when people refer to him as Agent Bell without him prompting them to.
* ExtremeGraphicalRepresentation
* HatesBeingTouched: Like real life autistics, except with people who have earned his trust like Dr. Rosen, his mother and, eventually, the other members of his team. Also, Anna once they become friends. Anyone else will provoke a reaction ranging from annoyance to outright hysteria, depending on circumstances.
** As of the season 2 premiere, where we learned he's been thrown in Binghamton and had a chip installed in him like all the other alphas there, he's regressed back to not letting anybody touch him.
* ImmuneToMindControl: Gary's autism makes him immune to mind control Alpha powers such as Nina's CompellingVoice. Something about his brain being too rigid.
* {{Jerkass}}: By his own admission, he has a "bad attitude". Although he's getting better, he seems to have some entitlement issues distinct from his autism.
** Though on the other hand, it's possible that with most high-functioning autistic individuals, he has resentment issues that people ''do'' treat him differently because of his autism, but on the other hand, he knows that in order to function properly, he need things to be done a certain way. It makes sense that he get annoyed by people who don't seem to grasp this and again, this is a rather normal response, given his high-functioning level of autism.
* LackOfEmpathy: Downplayed and justified - as with most people with autistic spectrum disorders, Gary tends to be oblivious to the feelings of others. It's not that he doesn't ''care'', though, and he's working on it.
* MyGreatestFailure: [[spoiler:Anna's death still weighs heavily on him in season 2.]]
* NoSenseOfPersonalSpace: He likes to read other peoples' texts and listen to phone calls.
* NoSocialSkills
* PapaWolf: Demonstrates this towards a Baby Alpha left temporarily in his care during one episode. Turns out, it's because the baby's ability is to literally invoke this state in people.
* PickyEater: Being autistic, he's very picky and specific about what he eats and drinks. Some of it because it's part of his routine to eat/drink a specific thing at a specific time or a specific amount of what he wants to eat (like in episode 1, where in his first scene, he uses cups to measure exactly the amount of cereal and milk he'll have for breakfast) while other times it's just a very specific craving he may have at that moment (such as in episode 7, where he says he wants to drink something purple, so Bill goes into a nearby gas station and buys every single purple drink he can find so Gary can choose the one he wants).
* {{Technopath}}: He can't really control technology, but can effortlessly read any signal coming from it.
* TookALevelInJerkass: He wasn't the nicest guy before, but after [[spoiler: getting tossed in Binghamton]] he's not really trying anymore.
* VitriolicBestBuds: Type 2 with Bill.
* WeaksauceWeakness: Can't detect Nokia traffic.
* TheWorldIsJustAwesome: After spending an extended amount of time in a dead zone, he learns to pick up on the electromagnetic signals generated by everything else. He learns to appreciate it pretty quickly.

!!Cameron Hicks
->'''Played by:''' Warren Christie\\

A former Marine Corps sniper and minor-league baseball player with [[SuperReflexes hyperkinesis]]. Hicks first encountered the team when a Red Flag villain used him as the patsy in an assassination; after freeing him from the villain's MindControl, Rosen recruited Hicks onto the team to keep him safe from the DOD. He has a young son that he rarely sees, and lots of {{UST}} with Nina.
* AwesomenessByAnalysis
* BelligerentSexualTension: With Nina, as of season two.
* BulletDodge: It helps that he knows where the bullets will be.
* DatingCatwoman: As Nina [[SarcasmMode delicately puts it]], he's "nailing [Rosen's] daughter," Dani, who is working for Stanton Parish. Hicks doesn't know about that, though, nor does anyone else until [[spoiler: "Falling"]].
* FakeDefector
* GlassCannon: Hicks' strength lies in being able to land precise, disabling blows, either with weapons or unarmed. However, he doesn't have the significant combat advantage that foes like [[PlayingWithFire Cornell Scipio]] or [[SuperStrength Jeff Kowalka]] do, so he tends to go down fast if they get a chance to get hit back.
* GunsAkimbo: Which his powers let him pull off despite the ordinary problems.
* HeWhoFightsMonsters: Sometimes becomes just as bad as enemies he fights.
* ImprobableAimingSkills
** ShootTheBullet: As of season 2.
* InTheBlood: In Series 2 he worries his son might have inherited his abilities, after watching him throw a can against the wall, ricochet off a bin-lid and land in another, without even ''looking''.
* LeParkour: As a part of his SuperReflexes.
* PopCulturedBadass
* PsychosomaticSuperpowerOutage: When under stress, his self-doubt makes his skills worse than the average person.
* RevengeBeforeReason: Often.
* SuperReflexes
* WouldHitAGirl: Like Bill, has no inhibitions about beating up {{Dark Action Girl}}s.

->'''Played by:''' Erin Way\\

A young Alpha that joins the team in season 2. She has PhotographicMemory which allows her to remember and reproduce anything she sees, at the cost of only being able to retain her memories for a month or so.
* ActionGirl
* AMillionIsAStatistic: Pulls this in the series finale when Harkin reminds her that 8 million people are about to die at Stanton Parrish's hands and she's just walking out on the team.
--> '''Kat:'''Yeah, and I don't know any of them. The only people I know are in that room, and they hung me out to dry.
* AmnesiacDissonance: Subverted; though her memory loss makes her fairly easy to manipulate, one such manipulator notes that she's always a Boy Scout-type with or without her memories.
* BewareTheNiceOnes: Despite what her GenkiGirl status and general friendliness would suggest, she can kick some ass. Just ask [[CrowningMomentOfAwesome Bill]] or [[ItsPersonal Dylan]].
** Or [[CarFu The Caretaker]]
* CarFu: She performs this with a ''Mack Truck''
* CursedWithAwesome: How she sees her power. She learns anything instantly, and the memory loss means no "rear-view mirror". Bill and Rosen try to convince her that some memories are worth holding onto.
** She later withdraws this claim, telling Hicks that he's lucky to have his memories.
* GenkiGirl
* JumpedAtTheCall: At the end of "Alpha Dogs", upon learning that Bill is a secret agent, she immediately asks Rosen to let her join the team.
--> '''Kat:''' You want me on your team. I'm awesome!
* LaserGuidedAmnesia: Her memory resets after a month or so. She can't remember her family, though she retains skills even after she's forgotten learning them in the first place.
* LeeroyJenkins: Downplayed, but still very much there.
* NoHoldsBarredBeatdown: Gives one to [[spoiler: Dylan in "Falling" after finding out what a dirty manipulative asshole he is.]]
* PhotographicMemory: Or rather, Photographic ''Muscle'' Memory. She can do pretty much anything she's read or watched, but her long-term memory resets after about a month.
* PintSizedPowerhouse: She's tiny, but her Alpha ability allows her to instantly learn WaifFu skills that let her utterly demolish Bill in a fight.
* SacrificedBasicSkillForAwesomeTraining: She's learned countless random skills, but basic swimming is not among them. Although being able to pick locks ''while underwater'' probably is, as Hicks finds out for himself.
* TheSmartGirl: Well, as smart as one can hope to be when one only has a month of long-term memory. She's able to figure out that the Alpha in "If Memory Serves" becomes too heavy to swim when he's healing simply by working out the meaning of the milk cartons he had in the farmhouse.

[[folder:Department of Defense]]
!!Don Wilson
->'''Played by:''' Callum Keith Rennie\\

An FBI agent who liaises between the government and Rosen's team. [[spoiler:Killed off in episode 3.]]
* ActorAllusion: Callum Keith Rennie is cast as a character who was shockingly killed off early in the season, after coming off a high-profile regular role in [[Series/BattlestarGalactica2003 a different show]] as a character known for his ResurrectiveImmortality.
* DeadStarWalking
* JerkAss
* MauveShirt
* TheMenInBlack
* NobleBigotWithABadge
* SacrificialLamb

!!Nathan Clay
->'''Played by:''' Mahershalalhashbaz Ali\\

The head of a DOD tactical-operations unit that deals with rogue Alphas and runs the Binghamton facility.
* TheCavalry: Often.
* CharacterDevelopment: Gained a bit in "The Unusual Suspects". Prior to that, he was just the [[{{Jerkass}} guy who went around detaining Alphas]]. The episode revealed that he was told it would be the fast track to promotion and ended up stuck in his position. Also, while he believes [[{{JerkassHasAPoint}} dangerous Alphas should be locked away or worse]], he tends [[{{PetTheDog}} to show leniency to those he considers mostly harmless.]]
* JerkAss: Started off as a big example of this, quickly became a solid example of JerkWithAHeartOfGold.
* PetTheDog:
** In "The Unusual Suspects", he doesn't give an order for a sniper [[spoiler: to use lethal force on Rosen's team during the break out when he could have.]]
** His interactions with the body reader Eric were pretty friendly, and he even authorized parole for him because he was not a threat.
** He makes a genuine effort to get Gary released from Building 7 in season 2, being acutely aware that it's not Gary's fault given how badly everything has gone since the last season. He also gives Rosen pretty much whatever he wants, even though it's clear he knows his superiors won't be happy with it.
* ReasonableAuthorityFigure: In Season 2, after his CharacterDevelopment.
* TheSixthRanger: When the team needs armed backup, it's usually Clay heading the charge.

!!Kathy Sullivan
->'''Played by:''' Valerie Cruz\\

A government agent and official liaison between Rosen's team and the DOD.
* ReasonableAuthorityFigure: She's a much friendlier, more level-headed boss than Wilson.
** Subverted in the season one finale "Original Sin" [[spoiler: when, against Rosen's pleas, she sends a heavily armed tactical squad to smoke out a group of Red Flag members discussing [[{{EnemyCivilWar}} going against their leader Stanton Parish]]. Unsurprisingly, a slaughter occurs; Alpha men and women are cut down, and Bill and Gary almost get killed in the confusion.]] Sullivan believes fully that it was a good thing. Surprisingly, [[DespairEventHorizon Rosen doesn't agree.]]
* NecessarilyEvil: While she considers herself Rosen's friend, she views the [[spoiler: slaughter of Red Flag members during the season one finale]] as a [[BlackandWhiteMorality victory that Rosen should be proud of.]] And offers him [[OrganizationWithUnlimitedFunding whatever he needs - Alphas, men, resources]] - to ''contain'' the Alpha Problem.
* WithUsOrAgainstUs: When it boils down to it, she views Alphas as a problem to be contained.

!!John Bennett
->'''Played by:''' Steve Byers\\

The team's new lead tactical officer in season 2. Hits it off with Rachel, despite a rocky start.
* BodyHorror: His left side is pretty messed up, having been burned in a vehicle fire when he was deployed overseas.
* NiceGuy: On a team of gifted superhumans with personality issues who are led by their shrink, his most immediately defining trait is how accepting and accommodating he is of them, especially considering how others from the Department of Defense tend to treat them.
* ShellShockedVeteran: Zig-Zagged. He is initially shown as being perfectly mentally healthy despite having fought in a War, but then he reveals the scarred left side of his body, and with it, mental scars regarding body image. However, outside of that issue, he is the most mentally balanced member of the team.
* TheTeamNormal: The only non-Alpha aside from Rosen.

[[folder:Red Flag]]
!!Anna Levy
->'''Played by:''' Liane Balaban\\

A woman whose Alpha ability allows her to understand and communicate (but not speak) in any language. In the episode "Rosetta", the team initially find her in a Red Flag safehouse and believe her to be a captive of the group, who use her abilities to encrypt their communications. [[spoiler:Turns out, she's one of the leaders of Red Flag.]] She and Gary become friends very quickly, and stay in contact even after the events of "Rosetta".
* AffablyEvil: At the more moderate end of Red Flag.
* DatingCatwoman: Her and Gary's friendship has strong echoes of this.
* {{Foil}}/ EvilCounterpart: For Gary.
* KilledOffForReal: [[spoiler:In the DOD raid during "Original Sin"]].
** NotQuiteDead: [[spoiler:A FreezeFrameBonus during a commercial shows graffiti that says "@Anna_Lives." This is a Website/{{Twitter}} [[CharacterBlog account]] seemingly owned by Anna, who responds to questions in-character. Turns out that it's just Gary, though, as a misguided way of honoring her memory.]]
* HeroicSacrifice: Sort of. The [[spoiler: hallucination]] of her convinces Gary to [[spoiler: let Doctor Rosen wake up the comatose teen whose Alpha ability was allowing her to appear to Gary in the first place]].
* InformedJudaism: We only learn that she was Jewish [[spoiler: at her headstone unveiling (think funeral, but a significant period after the actual death)]]. Liane Balaban, who plays her, is half-Jewish herself. Her last name, Levy, is common among Jews too.
* {{Omniglot}}: Her Alpha ability takes this up to eleven.

!!Dr. Kerns
->'''Played by:''' Creator/BrentSpiner\\

An obstetrician and member of Red Flag. He's completely blind, but has a sonic-based Alpha ability that allows him to "see" using echolocation. [[spoiler:He planned on giving deliberately-altered pre-natal vitamins to pregnant women in the hopes of creating more Alphas, but Rosen's team caught him first, and he was later killed by Griffin]].
* DisabilitySuperpower
* KilledOffForReal
* LethalHarmlessPowers: [[spoiler: Turns out his sonic powers are way more dangerous than just sonar.]]
* MakeMeWannaShout: With some buildup, his Alpha ability eventually lets Kerns do this.

!!Danielle Rosen
->'''Played by''': Kathleen Munroe\\

Dr. Rosen's estranged daughter, whose Alpha ability lets her force emotions onto other people. After stealing something from Red Flag, she meets Rosen again in the season 1 finale when he saves her from a Red Flag assassin. [[spoiler:Secretly working for Stanton Parrish]].
* AbusiveParent: Danielle accuses Dr. Rosen of being this. When his marriage was in trouble he had Danielle use her power on her mother to calm her down. He continued doing this for years after he found out about his daughter's Alpha power and that using her power was causing serious damage to her. (To Rosen's credit, he admits she was right and apologizes.)
* ConflictingLoyalty: Her different forms of love for her father and Hicks, versus her standing loyalty to [[spoiler: Stanton Parish]].
* DespairEventHorizon: An incredibly heartbreaking one at the end of "Falling".
* TheEmpath: Dani can manipulate the emotions of those around her through touch. As a straighter example, she can also detect (and reproduce) someone's exact emotional state in the same manner, a skill which she uses to help Hicks bond with his son after an argument (by showing them how the other feels).
* HeelFaceTurn: [[spoiler:A slow one, ending in RedemptionEqualsDeath.]]
* KilledOffForReal
* TheMole
* PowerPerversionPotential: Uses it.
* RedemptionEqualsDeath
* SeriesContinuityError: In season one's "Original Sin" her middle name was Sophia, yet in season two's "Life After Death" it was Sarah.
* SoProudOfYou: Said to her by [[spoiler:Stanton Parish, moments before he detonates an electrical bomb which kills her]].

!!Stanton Parrish
->'''Played by:''' John Pyper-Ferguson\\

The immortal leader of Red Flag and one of the oldest-known Alphas, his existence wasn't discovered until the season 1 finale, "Original Sin". He's determined to wage war on humanity and to keep the existence of Alphas a secret from the general public.
* AffablyEvil: Impeccably polite (though certainly antagonistic) with Rosen.
** Put on display again in the season two premiere when he makes a point to ask Danielle how Rosen is faring and expresses joy at his good fortune. He even hopes that Rosen will join him, though he's not so arrogant that he believes Rosen will just do it on a whim.
* TheAgeless: Been alive since the Civil War.
* {{Archenemy}}: To Rosen.
* AntiVillain
* BadassInANiceSuit: Often found in a stylish grey suit.
* BadassLongcoat
* BeardOfEvil: A rockin' goatee.
* BigBad
* TheChessmaster: Effortlessly turned every single main character into an unwitting pawn to further his goals.
** Continues to embody this trope into season two.
* ClockKing: Demonstrates traits of this from time to time, in particular in the season two finale. He even uses a golden pocketwatch like the TropeNamer.
* CulturedBadass
* DarkMessiah: Not as blatant as most examples of this trope, but it is pretty clear he acts as a Messianic figure for Red Flag members.
* DoNotCallMePaul: He prefers his current name over his birth name.
* EvenEvilHasLovedOnes: He seems to have a genuine soft spot where Dani is concerned.
* EvilCounterpart: Serves as one to [[GuileHero Dr. Rosen]]. Both are highly intelligent, noble and cultured leaders of a group of Alphas, both can get into people's heads and only wish the best for the Alphas. (Though they have distinctly different ideas to what "the best" is.)
* EvilMentor: To [[spoiler: Dani]]. In the second 2 finale [[spoiler: he attempts to be this for Rosen, but it fails]].
* {{Expy}}: He's basically ComicBook/{{Magneto}} mixed with ComicBook/VandalSavage.
* GeniusBruiser: He's a very manipulative, cunning, extremely well-read soldier. Also manages to kill two SWAT soldiers in less than ten seconds while completely unarmed.
* GoodThingYouCanHeal: He can heal a ''shot to the head''.
* HealingFactor
* HeelRealization: Suffers one after [[spoiler: he slays Dani. That culminates with him trying to leave the Alpha Utopia for Rosen]].
* HeKnowsTooMuch[=/=]KilledToUpholdTheMasquerade: The doctor who studied his immortality wanted to publish his findings, so Stanton killed him.
* ImmortalityImmorality
* KillAllHumans: Well, kill all ''non-Alpha'' humans.
* MacGyvering: Makes a knife with a plastic cup of water.
* MasterOfYourDomain: This is either the cause or a side-effect of his immortality.
* MercyKill: [[spoiler: Does this to one of his granddaughters, to spare her from suffering]].
* MyGodWhatHaveIDone: Without the dramatics typically present for the trope, but he seems to feel quite a bit of guilt over [[spoiler: killing Dani to further his cause]], as shown in "If Memory Serves".
* MyGreatestFailure: He seems to genuinely regret not being able to find an alternative to his KillAllHumans plan:
-->'''Rosen:''' She (Danielle) knew there was a better way.\\
'''Parrish:''' ''(sadly)'' I couldn't find it.
* MySkullRunnethOver: Implied in "If Memory Serves", with Hicks making a comparison to old-age dementia (as noted in the Real Life section on that page). Being over 200 years old, he keeps around an Alpha who can record memories, evidently as a sort of back-up drive.
* NecessaryEvil: Holds no illusions that what he is doing is evil, but he thinks it needs to be done.
* NobleDemon: He has a solid code of honor, even allowing [[spoiler:Danielle]] and Hicks to stay together, despite being on opposite sides.
** Though this was obviously [[TheChessmaster to use her as a better mole]], which she was due to their relationship.
* NoPlaceForMeThere: In the season 2 finale, he reveals to Rosen that he always intended Rosen to be the leader, not himself, because his plan would make him a mass murderer unfit for such leadership.
* NotSoDifferent: Argues this about himself and Rosen, while he does have some solid points, Rosen is less than convinced.
* NotSoStoic: His cool-headed attitude visibly cracks [[spoiler: when Dani says she will die for what she believes in]], and ventures into a full-on VillainousBreakdown as his master plan comes to fruition while Rosen closes in.
* OldSoldier: He fought in the US Civil War, the Spanish-American War and both World Wars.
* PsychologicalCombat: This is practically his greatest weapon; case in point, he managed to lay havoc in Gary's mind with about two phrases.
* Really700YearsOld: At least as old as the Civil War.
* ResurrectiveImmortality
* SharpDressedMan
* TheSociopath: He is a subversion. Rosen was at first insistant that he was one, but after meeting Mitchell, who Parish was using as an emotional confidant, Rosen decides he misjudged Parish. [[spoiler: His humanity is his weakness]]
* UtopiaJustifiesTheMeans: Seeks to create an Alpha utopia.
* VillainousBreakdown: Suffering from early signs: His calm, cool-headed ways are slowly slipping away, and he loses his patience more easily as Rosen starts to threaten his plans.
* WarriorPoet: He is soldier who fought in four different wars (and is trying to trigger a fifth), but a philosopher, lover of the arts and political idealist.
* WellIntentionedExtremist: Or so he claims. [[spoiler:As he tells Dani, he believes that overpopulation will kill the planet in forty years, and is willing to commit mass murder to stop that.]]
* WhoWantsToLiveForever[=/=]LivingForeverIsAwesome: Zig-Zagged. Parish remarks that due to/because of his control over his mind and body he is far beyond human potential as well as functionally immortal. On the other hand, he and [[spoiler: Danielle]] both later note that no parent should have to bury his own grandchild (Parish has had 31, all of which have died).

!!Cornell Scipio
-> Played By: Elias Touxefis.
A man who escaped from Binghamton at the start of Season 2, now seems to work for Parish as one of his main lieutenants.
* BeardOfEvil: A very unsubtle goatee.
* TheDragon: To Parish.
* DeadpanSnarker
* EvenEvilHasLovedOnes
* {{Expy}}: A RaceLift version of Tike Alicar/the Anarchist from ''[[ComicBook/XForce X-Force/X-Statix]]''.
* FauxAffablyEvil: Keeps talking to Rosen in friendly way, even when he's about to murder him.
* HannibalLecture: Attempts one in Rosen when he's held captive. It [[StealthPun backfires]] ''hard''.
* HoistByHisOwnPetard: [[spoiler: Invoked by Rosen making Scipio burn himself to get some information.]]
* NumberTwo: Although others, notably [[spoiler:Dani]], could be interpreted in this way, in season 2 he's usually Parish's squad leader for various missions.
* PlayingWithFire: His power is a lessened version of this, he can only cause severe burns to people he touches, not actually burn things. [[spoiler:Of course, that changes when Rosen upgrades his Alpha ability to actual PlayingWithFire]].
* RequiredSecondaryPowers: As his fire-starting sweat is released through his palms, that area is necessarily fireproof to keep him from burning himself. Unfortunately, the rest of him isn't.
* SelfMadeOrphan: [[spoiler:Apparently accidentally killed his parents 20 years ago with his ability]]
* ThenLetMeBeEvil: He asks if Rosen can fix him so he can be "human", when the answer is no, this is his reaction [[spoiler: it might have been just a part of the ruse, but the implication is still there]].
* UncertainDoom: After "Need to Know", we aren't known of Scipio's fate. A downer example because because there will be no season three. After the news of the cancellation, Elias Toufexis (Scipio's actor) tweeted that he was just going to pretend Scipio died in episode 13.
* WithUsOrAgainstUs

!!Kimi Milard
-> Played By: Sarah Slywchuk.
Another member of Parish's ranks, alongside Scipio, one of the main lieutenants who escaped from Binghamton.
* CharmPerson: Much like Nina, only voice-based.
** CompellingVoice: She only seems to whisper, however.
* EvilCounterpart[=/=]{{Foil}}: To Nina.
* TheDarkChick
* TheDreaded: Minor case, but Clay went OhCrap when she revealed herself in the breakout.
* KissOfDeath
* MeaningfulName: The Native American meaning of the name Kimi is "secret", reflecting Kimi Milard's method of induction by whispering in someone's ear.
* PsychoForHire
* TheVoiceless: Curiously, her power works through voice, but we only see her whispering unknown dialogue. She never openly says anything on-screen.

!!Jeff Kowalka
-> Played by: Jameson Kraemer.
Another member of Scipio's team, first faced the team on a failed robbery. His powers are exactly like Bill's.
* ArrogantKungFuGuy
* BloodKnight
* TheBrute
** Ascends to TheDragon in season two [[spoiler: after Scipio is arrested]]
* EvilCounterpart / {{Foil}}: To Bill.
* SmugSnake: Which is driven home when [[spoiler: Bill punches him across a room]].
* SuperStrength

!!Agnes Walker
A psychic who serves as the living lie-detector for Parish, to test new recruit's alliances, can scan other people's minds with touch.
* AffablyEvil: Remains polite with Hicks even as he's agonizing.
* AntiVillain
* BlessedWithSuck: Along similar lines to [[ComicBook/XMen Rogue]], she can scan people's minds with her touch, but causes incredible pain to them doing so. And she can't turn it off.
* EvilCounterpart: As she notes, she's technically (power-wise, if not personality-wise) one to Dani.
* EvilGenius
* NobleDemon: [[spoiler: Lets Hicks walk off when he allows her a last peak in his mind]]
* PunchClockVillain

!!Mitchell Morgan
-> Sean Astin.
An Alpha with the skill to store and reproduce anyone's memories, though this overrides his own sense of identity. Has a close relationship with Parish.
* {{Adorkable}}
* {{Cloudcuckoolander}}: Though it isn't his fault, his mind is overhwhelmed with other people's memories and he can't tell them apart.
* BlessedWithSuck: See above.
* MoralityPet: For Parrish, who cares deeply about him.
* TheRainman: Very child-like in his ways, but also a very skilled Alpha.
* OnlyFriend: Seems to be this to Parrish himself.

!!Dr. Vanessa Calder
->'''Played by:''' LindsayWagner\\

A medical doctor working for the CDC, who meets Rosen and the team while investigating a possible disease outbreak in "Never Let Me Go".
* CrossOver: Calder is a recurring character on ''Series/{{Warehouse 13}}'', another Syfy show, which means that ''Series/{{Alphas}}'' and ''Warehouse 13'' (and, by extension, ''Series/{{Eureka}}'') exist in the same universe.

!!Skylar Adams
->'''Played by''': Creator/SummerGlau\\

A GadgeteerGenius, and one of the first Alphas that Rosen's team ever helped (well before the start of the series). She goes on the run in "Catch and Release" from [[spoiler:her NSA handlers, after reneging on a deal to create advanced technology for the government. At the end of the episode, Rosen helps her disappear.]]
* CrazyPrepared
* GadgeteerGenius: Her ability actually manifests as a holographic representation of the device in question that she can assemble and disassemble with her mind. She can create a vast array of devices (one of the first we see is a device that used only 10 minutes a night will make the user feel like they got a full 8 hour sleep), and earns a living by rather covertly selling these out to people.
* MamaBear: She's not the best mother, but she ''deeply'' cares for Zoe.
* MoreThanMindControl: How Parrish gets her to work for him
* ParentsAsPeople: She's having a [[MaternallyChallenged hard time]] adjusting to being a full-time parent after years of hiding her daughter, and she resents having to sacrifice her lifestyle to give her daughter a happy childhood, but she'd do anything for Zoe.
* PetTheDog: The Department of Defense let her live a normal life for many years after her Alpha ability was discovered, whereas they tried to kill or lock up every other Alpha the team had encountered during the series.
* ProperlyParanoid
* ReedRichardsIsUseless: Inverted. her abilities are extremely useful, to the point that [[spoiler: she's able to invent technology that is beyond ''anyone'' else. The NSA makes good use of it until she goes off on her own]]. She actually plays a very significant role in thwarting Stanton Parrish's plans in the season 2 finale.
* TrueNeutral: While slightly (emphasis on ''slightly'') friendlier to Rosen and his team, she is aggressively neutral in the whole DOD/ Red Flag and DOD/ Parrish struggles. However, Parrish is able to get her to build machines for him thanks to MoreThanMindControl

->'''Played by''': Creator/RebeccaMader\\

A bounty hunter whose Alpha ability allows her to move through people's "blind spot" and remain almost undetectable. She's hired by Red Flag in episode 9 to retrieve Dr. Kerns.
* BountyHunter
* {{Deadpan Snarker}}
* [[InvisibleMan Invisible Woman]]: Never actually turns invisible (her power doesn't affect recordings), but she might as well be.
* MeaningfulName: [[Literature/TheInvisibleMan Guess.]]
* PerceptionFilter: The exact nature of her power.
* WhatHappenedToTheMouse: She appeared in one episode, gave the team's first major clue about Red Flag, then vanished off the plot.

!!Marcus Ayers
->'''Played by''': Will [=McCormack=]\\

An Alpha and former patient of Dr. Rosen, with ablities similar to Hicks. Suffers from severe paranoia and [[http://en.wikipedia.org/wiki/Apophenia aphophenia]] due the precognitive nature of his powers. Went around attacking the doctors who worked with him when he realised they were going to attempt to remove his Alpha ability through surgery. [[spoiler: Is shot by Clay and falls into a river below]].
* AwesomenessByAnalysis[=/=]HyperAwareness: Marcus's main ability is this, taken UpToEleven. He notices ''everything'' to the point that he can accurately predict the future. Further more he can influence the future and manipulate his environment to get any desired result.
* BatmanGambit: Was proven right in assuming that [[spoiler: Clay would shoot him for kidnapping Rosen]], and uses it justify his [[WithUsOrAgainstUs Us vs. Them mentality]]
* ChessMotifs: Played chess with Rosen in the past, and part of his world view is that every single thing a person does is like a chess move on their part to accomplish a goal.
* EvilCounterpart: To Hicks.
* IThoughtEveryOneCouldDoThat: This is the basis for his paranoia - he can't comprehend that ordinary people are unable to do what he does, so he assumes that everything anyone does must be a calculated move, including those things that resulted in his institutionalization.
* LackOfEmpathy: His powers give him a good idea of how just about everything around him will play out to the most minute detail, and he's unable to empathize with people who can't see the world as he does.
* NeverFoundTheBody
* OffscreenMomentOfAwesome: Somehow got one of his victims (who was on ground level) impaled on a spike about two stories high on a building in a matter of seconds with a cart and some wire.
* RubeGoldbergHatesYourGuts: The most violent application of his powers.
* SuperReflexes
* ThereAreNoCoincidences: To him, everything that any person does is deliberate, and usually as an attack against himself.
** In a conversation with Rosen, he recalls how a wild party that his roomates threw in college is what indirectly got him institutionalized, and he views it as a deliberate slight against him by his roomates.
