    In General
The AI units used by Project Freelancer play a large role in the ongoing plot of the series. The Director used the AIs to experiment with their abilities to enhance the performance of their hosts, but was only able to acquire a single AI under UNSC law. This AI was the Alpha, and was based on himself. To create other AIs, the Director tortured the Alpha with elaborate scenarios, causing it to splinter into other AIs, like split personalities. These AIs, each based on one aspect of the Alpha, were harvested and given to the agents one by one. The exception was Beta - as she was not created as a result of torture, instead of the memories of someone the Director loved dearly, she was given a robotic body, and accepted into the project as one of the agents - Tex.

When the Chairman of the UNSC Oversight Sub-Committee became conscious of the fact that Project Freelancer had acquired more than one AI, and the project was ultimately disbanded, the Alpha was sent to live, unaware of its identity as an AI, in Blood Gulch, as Private Leonard Church, a member of the practice armies Project Freelancer had used. After the events of The Blood Gulch Chronicles, the AIs were rounded up, their hosts murdered, by "The Meta" (Agent Maine, under his AI Sigma's controlling influence), until they were all destroyed, along with all other Freelancer equipment in the EMP blast initiated by the Alpha himself.

The only AI to survive the blast was Epsilon (Alpha's memories), whom Caboose reactivated and explained what had happened after the Alpha was moved to Blood Gulch, thereby "recreating" Church. Since Epsilon had the memories of the complete Alpha, it also had the memories of all the other AIs, and has now controlled the ability to duplicate them without losing his own form, essentially bringing them back in some way or another.

Associated Tropes:

  • A.I. Is a Crapshoot: They are deliberately warned about the dangers of rampancy, an issue in the Halo universe.
    • Made all the more ironic given the fact that most of them are a result of driving an AI completely insane over and over again.
  • Anthropomorphic Personification: All of them except the Alpha are some defining attribute of the Alpha that it sheared off.
  • Artificial Intelligence: It's what they are, as the page title may indicate.
  • Back from the Dead: While the original AIs are all technically dead, Epsilon brings them back in the form of his memories after Season 10. He actively suppresses the copies of Omega and Sigma, and spends time talking to and joking with Delta and Theta. According to Word of God from the Afterbuzz stream, after Epsilon's Heroic Sacrifice the Fragments are back, but in a more "potent" form, condensed down to their core attributes. However, they all died again after the fight, rendering the suit useless.
  • Blue and Orange Morality: As noted multiple times, the A.I.s are not ones who view morality as a human may, leading to their actions being strange and occasionally chaotic to anyone not following their mindset.
  • Color-Coded for Your Convenience: Much like the agents, though AI also have other physical ways to distinguish themselves, such as animation styles or whether or not they are wearing a helmet.
  • Digital Avatar: How they present themselves. By the end of Season 6, we had seen almost all of them, with Epsilon being the last one, having to make one for himself.
  • Doomed by Canon: In Season 9 and 10, all of the AIs except for Epsilon are this, due to having been killed off at the end of Reconstruction.
  • Embodiment of Vice: Omega is the personification of Alpha's rage, and Gamma personifies deceit. Sigma is said to embody Alpha's ambition and creativity, which aren't bad traits per say, but he certainly gives them an evil spin. Connie's files on Project Freelancer also mention the "Greed" AI, although it hasn't appeared on-screen, even if it had actually existed.
  • Enemy Without: Omega and Gamma to the Alpha during The Blood Gulch Chronicles. The rest of them end up antagonizing their progenitor in The Recollection and The Project Freelancer Saga.
  • Flanderization: An in-universe example. Due to the nature of memory, the recreations of the fragments caused by Epsilon's splitting are more "potent", and their core attributes are emphasized.
  • Gratuitous Greek: All the artificial intelligences are named after letters of the Greek alphabet. They all come from a single intelligence, the Alpha, that had parts of it that controlled specific emotions grafted off and turned into intelligences of their own. The letter each AI is matched with is somewhat significant; take Omega, named after the last letter, who's made from the Alpha's hatred and as such, is very likely to end you.
  • Literal Split Personality: All of them but the Alpha and Beta are fragments sheared off by the Alpha and captured by the Engineer at Project Freelancer.
  • Made of Evil: Gamma, Sigma and Omega are the personifications of Alpha's deceit, ambition and rage respectively. See Embodiment of Vice above.
  • Phlebotinum-Handling Equipment: For certain armor enhancements.
  • Projected Man: How they typically present themselves, almost all of them being in armor like their partnered agents.
  • Restraining Bolt: Of a sort. It's incredibly dangerous to activate armor enhancements without an AI to help run them. Otherwise, the power is likely to short out, overdo it, or kill the user.
  • Robot Buddy: That is, if they aren't more malicious.
  • Shell-Shocked Veteran: The fragments are known to have symptoms of post-traumatic stress disorder after the method for creating them.
    York: I wonder if they're all like this, the A.I.s. You know, jittery, nervous, no, not nervous...
    North Dakota: Anxious.
    York: Yeah. Anxious. It's like Delta always thinks that something bad is always about to happen. I don't get it. What do they have to worry about?
  • Sliding Scale of Robot Intelligence: All over the place. Delta and the complete Alpha seem in the range of Nobel Bot, but the rest seem more like an Average Joe Android, but with more emotion and interpersonal skills.
  • Walking Spoiler: Their true nature isn't revealed until Reconstruction, with further reveals to cement them in this status.


Omega (O'Malley)
Voiced By: Burnie Burns (Default voice and while possessing Tex), Joel Heyman (while possessing Caboose), Matt Hullum (while possessing Doc, "Head Cannon")
Attribute: Rage

"I will devour their hearts and crap out their souls! They will all taste oblivion! Which tastes just like Red Bull...which is disgusting."

The Arc Villain of the Blood Gulch Chronicles, Omega was the AI partner assigned to Tex as part of the Freelancer program ("O'Malley" is a portmanteau of their names, Omega and Allison). While Tex was already, according to Church, "a rotten bitch," the addition of Omega turned her into "a rotten bitch with cybernetic enhancements." After the Freelancer program was shut down following Agent Washington's breakdown (see below), Omega possessed Tex and fled the facility before he could be removed. A bloodthirsty and malevolent AI, O'Malley was capable of possessing soldiers via their helmet radios like a virus. Once Tex was killed, O'Malley briefly possessed Caboose (and may have contributed towards his drop in intelligence), then seized the medic Frank DuFresne (see below) up until the finale. Though a real danger, O'Malley's dialogue frequently dips into cartoonish levels of villainy.

Reconstruction revealed that Omega was actually a fragment of the Alpha, the AI given to Project Freelancer which was subsequently tortured into fragmenting. Omega inherited the Alpha's anger, which explains O'Malley's ability to inspire fury in those it possessed, as well as the Alpha's ability to travel via radio transmissions. Omega was recovered by the Meta (see below) and was destroyed at the end of the series.

Associated Tropes:

  • Affably Evil: During the Blood Gulch Chronicles. He may have been an insane megalomaniac, but he spent most of his time bickering with Doc or being a Laughably Evil Large Ham.
  • A.I. Is a Crapshoot: The most noticeable in the series. Than again, it's justified as he's made of rage.
  • Anti-Hero: When he manifest himself as a Split Personality inside of Doc. He's on the side of the good guys, but he's still the Ax-Crazy megalomaniac we all know and love.
  • Arch-Enemy: To Church. Almost all the problems he has can be traced back to Omega. Hell, he even gives Epislon!Church some trouble.
  • Arc Villain: Of the Blood Gulch Chronicles.
  • Ax-Crazy: Being the personification of rage can do that to an AI.
  • Big Bad: Of the Blood Gulch Chronicles. Although he is Laughably Evil, his actions against the Reds and Blues as well as his world domination efforts are the primary reason for the situation the Reds and Blues are in.
  • Big Bad Wannabe: Was effectively the main antagonist for the first five seasons, but O'Malley was portrayed more along the lines of a Large Ham parody of the Big Bad archetype.
  • Body Surf: Omega can switch from host to host through inhabiting their minds if their built-in helmet radios are on.
  • Card-Carrying Villain: That's at least the affect he has on those he possess.
  • Cerebus Retcon: Omega in Seasons 1-5 is largely an ineffectual random villain. In season 6 onward, he's a completely dangerous psychopath. In Episode 13 of Season 10, Sigma and Gamma describe Omega as the most powerful of the Freelancer A.I.s, stating that "Omega's strength is unmatched. I don't know if anyone could beat him." Granted, Sigma and Gamma aren't exactly the most reliable sources of informationnote  and are clearly manipulating Carolina into doing something rash. However, it does in hindsight make Church beating Omega out of Caboose's head at the end of the Blood Gulch Chronicles something of a CMOA.
  • The Corrupter:
    • Whenever Omega possesses someone, he changes their behaviors into something that's somewhat more in line with his own personality, along with essentially amplifying their own negative traits ten-fold. Inside Tex, he gave no indication of presence or even sentience, and merely made her more bitter. Inside Caboose, he was more of a random psychopath. It isn't until he possesses Doc that he gets any aspirations towards omnicide.
    • From Walter's description at the first episode of Reconstruction, Omega's sting at possessing the Blues stationed at Valhalla was more... brutal, to put it mildly.
    • He also seems to have a corrupting influence on Doc to some degree. Even after Omega is gone, Doc actually starts cursing, speaking more offensively, and is more lenient about violence. Though this might also be attributable to hanging out with the Reds and Blues. This comes to a head in Season 13, where Omega apparently had enough influence on Doc that when Doc went nuts, he gained a split personality that's a perfect imitation of O'Malley.
  • Demonic Possession: Kind of, more like Evil AI Possession.
  • Disc-One Final Boss: He is the final enemy of The Blood Gulch Chronicles, which is the first story arc in the series.
  • The Dreaded: His laugh is enough to make Felix whimper in fear.
  • Eviler Than Thou: Believe it or not, YES. He pulls this on Felix in the season 13 finale.
  • Evil Is Hammy: He's a megalomaniac. It shows, from the Evil Laugh to the flourished speech.
  • Evil Is Not a Toy: In the final two episodes of The Blood Gulch Chronicles, it's revealed that the UNSC/Freelancer Command's ultimate plan to win the war with the Aliens was to have Omega possess Junior (their Chosen One) and use him to take over their religion and subvert it from the inside. In short, their plan to bring about peace was to hand over an entire alien army to the guy who was literally made of hatred. Church even points out what an incredibly stupid plan this is.
  • Evil Sounds Deep: When taking control of another person, he uses a lower pitched version of their voice. When possessing Doc he also has a weird accent added on.
  • Face–Heel Turn: Tortured the Alpha after being fractured off from him.
    • Heel–Face Turn: When he returns as a split personality inside Doc's head. While he still dishes out threats and beat the shit out of Tucker, he allowed Doc to partake in combat alongside the army of Chorus.
  • Knight of Cerebus: The majority of his time spent in Blood Gulch averted this, but in Reconstruction he gets darker and darker through flashbacks. Especially with the revelation of his torturing the Alpha. Though his return in season 13 brings him back to Laughably Evil.
  • Lamarck Was Right: Due to a very literal case of Powers as Programs, Omega inherited his ability to Body Surf from the Alpha, his source Smart AI.
  • Large Ham: Very, very much so, at least in The Blood Gulch Chronicles.
  • Laughably Evil: Omega, in Doc's body, is too ineffectual and hammy to be taken seriously. In the Reconstruction series and after that, however, he crosses into more horrifying territory with the description of his encounter with another group of soldiers and Tex's revelation that Omega ruthlessly tortured the Alpha. He returns to this when he comes back in season 13.
  • Not-So-Harmless Villain: In Episode 15 of Season 10, we get Omega urging Tex to kill Carolina, who by that point was immobilized by the two AI in her head. And unlike all those threats he made in the Blood Gulch Chronicles, this was played completely straight. He also speaks in a genuinely intimidating deep, gutteral growl that wouldn't sound out of place coming out of the Meta.
  • Portmanteau: O'Malley —> Om-Alli (Omega-Allison)
  • Robotic Psychopath: He's an Ax-Crazy A.I. made of rage and hatred.
  • Starter Villain: The first enemy the Blood Gulch Crew had to Enemy Mine against to defeat. Due to a combination of being inside of Doc and having to rely on the bodiless Lopez, he wasn't so much "A threat to the galaxy" as he was really annoying, especially when compared to later antagonists, such as The Meta, Project Freelancer, and Charon Industries. But, as the Omega-based split personality inside of Doc tells Felix…
    "Oh, please. I'm the original bad boy. Muhahaha."
  • Take Over the World: A hilarious parody of this type of villain in The Blood Gulch Chronicles. Works especially well when he's in the body of a pacifist.
  • Unstoppable Rage: He's literally formed from the Alpha's rage.
  • Villain Decay: Inverted. During the Blood Gulch Chronicles he's a Laughably Evil Harmless Villain. Starting in Season 6 he's portrayed as far more dangerous with a recount of how he drove an outpost of simulation troopers to kill each other.
  • Villainous Legacy: Even after death, some of his personality still remains in Caboose, who can manifest it when angry. Eventually, Doc's O'Malley personality comes back as well after being trapped in limbo from the teleportation grenade.


Gamma (Gary)
Voiced By: Mac OS X Fred
Attribute: Deceit


Encountered by the Red and Blue Teams in the form of an ancient computer built by the aliens as an expert on humans, who then proceeds to warn them about a vague prophecy. They eventually figure out that Gary is really Gamma, Wyoming's AI (the name "Gary" is a portmanteau of "Gamma" and "Reginald", and Burnie Burns has revealed the it is the same name of his late cat). Gamma was evidently the personification of the Alpha AI's deceit, and is described as having removed itself from Wyoming, with potentially harmful results. In the end, they reunite during their attempt to kidnap Junior. Gamma was another one of those AIs recovered by the Meta during Reconstruction. It had a strange fondness for knock-knock jokes.

Associated Tropes:

  • Affably Evil: Initially seems to be this, especially as "Gary".
  • A.I. Is a Crapshoot: However, this is less of a problem to his operator than to others he comes in contact with.
  • Bald of Evil: He's basically a blue, laggy twin to Sigma.
  • Catchphrase: "Knock-knock."
  • Cold-Blooded Torture: Burnie Burns has revealed that the entire "time travel" aspect of Season 3 was just an instantaneous torture scenario built by Gamma for the Alpha.
  • Creepy Monotone: Him literally being voiced by a computer gives off this effect.
  • Even Evil Has Loved Ones: He seems to actually be upset by Wyoming's death (see Little "No" below)
  • Evil All Along: Same with Vic, more or less.
  • Evil Genius: For O'Malley, Wyoming and Vic, arguably.
  • Evil Has a Bad Sense of Humor: The second type, though his jokes are just corny instead of being twisted.
  • Face–Heel Turn: Tortured the Alpha along with Sigma and Omega after being split from him.
  • Faux Affably Evil: Eventually turns out to be this.
  • Foreshadowing: In "Out of Mind", York refers to the fact that "Reginald" always told stupid knock knock jokes in reference to the merger between A.I.s and their partners. Astute viewers will take this, the fact that York says "Speak of the Devil" after Wyoming is mentioned, and the fact that "O'Malley" is a portmanteau of Tex's real name (Allison) and Omega, in order to realize that the time bending, knock-knock joke spouting A.I. Gary is actually Wyoming's partner.
  • For the Evulz: There was no reason for him to put Church through a time-travelling scenario, convincing him that he could avert the events of the series. He just did it to be a jackass.
  • Hidden Agenda Villain: Even after everything has concluded, Gamma's motives through the story remain unclear. Was he planning to become a part of the Meta from the start? Was he as dedicated to winning the Human-Covenant war as Wyoming was? Was he just doing random things For the Evulz? We might never know.
  • Kick the Dog: Killed Caboose at least once, despite posing no real threat to him. And was the one who make Church suffer the mental breakdown that created Epsilon.
  • Laughably Evil: Even the supercomputer, but only in The Blood Gulch Chronicles.
  • Little "No": When Tucker stabs Wyoming.
    Gamma: Reggie.
  • Manipulative Bastard: Personification of deceit, after all. It's even worse when he and Sigma are working together.
  • Portmanteau: Gary is a mix of Gamma and Reginald (Ga-Re), it's also the name of Burnie Burns' late cat.
  • Robot Buddy: A rare example of him being both this and A.I. Is a Crapshoot. Upon splitting from the Alpha, he began torturing him alongside Sigma and Omega, and is overall malicious. However, he's rather nice around Church while in his fake thousands of years of a Stable Time Loop, to the point of them spending a lot of time telling jokes to each other. He is also upset, saying the birth name of his operator (rather than Code Name), when said operator's last known Stable Time Loop created copy dies. When Epsilon is shown working with the Living Memory duplicates he made of the Alpha's fragments in season 12, he visibly distrusts Sigma and Omega but trusts Gamma enough to give him a job to do.
  • Shoo Out the Clowns: He hasn't been given a speaking role since Season 5, because his character no longer fits with the more serious plot. Subverted by Season 10, when he returns, although his humor has been dropped entirely.
  • Villainous Friendship: Heavily implied by his anguish at Wyoming's chronologically final copy dying.
  • Villain Team-Up: With Sigma as of the flashback in Episode 13 of Season 10.
  • Write Who You Know: In-Universe. The reason why the original A.I. of Sheila is named F.I.L.S.S. in the "time travel" plot of Season 3 is because that is the name of the A.I. in what Gamma remembers from Project Freelancer, who has the same voice.


Voiced By: Mark Bellman
Attribute: Logic

"Hello. How may I be of assistance?"

An AI formed from the Alpha's logic centers, and as a result has a cool and calculating personality, calmly informing his partner of attackers' locations and running the numbers to predict their behavior. He starts out as York's AI, but after the Out of Mind side arc, he ends up working with Agents South Dakota and Washington during the Recovery One series, and is introduced to the Blues during Reconstruction. Of all the Freelancer AIs, Delta is the most fervent believer in the existence of the Alpha, and leaves clues that inspire Washington to try to unlock it. Presumed destroyed after being captured by the Meta, who in turn was hit by the E.M.P. His holographic avatar is bright green.

Recreation reveals that Epsilon houses memories of all the Alpha fragments. Delta appears to give advice and information on their behalf to Caboose. He also was transferred into the Forerunner Monitor along with Epsilon. Whether he is still exists as a separate consciousness or has been fully assimilated into Epsilon has yet to be revealed.

Associated Tropes:

  • Art Shift: No matter which format the videos are being made in, Delta is filmed using Halo: Combat Evolved footage. Particularly evident in later seasons.
  • A Form You Are Comfortable With: When speaking to Caboose, Epsilon takes on Delta's form for this purpose. Caboose being Caboose, though, the effect is somewhat wasted.
  • Blue and Orange Morality: He comments in "Out of Mind" that "good and evil are human constructs", and tends to focus on whatever produces the most logical, optimal, and courteous result. He'll do things like wish an enemy good luck, attempt to talk one into helping with a What Is Evil? speech, suggest Kick the Dog solutions, or even outright admit he might side with the enemy... while simultaneously performing acts of aid, kindness, self-sacrifice, and loyalty to his allies and bystanders as well. All with a blandly friendly, sincere, and non-malicious demeanor.
  • Breakout Character: At this point, Delta has received the most screen time of any AI character (excluding Church and Tex). He's incredibly popular among both the staff and the fans, and some form of him has appeared at least once a season since Reconstruction, despite being technically killed off at the end of said season.
  • Crazy-Prepared: In order to make sure he survives if 479er makes a fatal crash in Episode 8 of Season 10, he makes a backup of himself.
    Four Seven Niner: Wait a second, why did you just blink like that?
    Delta: That was just a standard maintenance routine.
    Four Seven Niner: Dude! Did you just make a backup of yourself?
    Delta: Confidence is one thing, but it is always prudent to prepare for failure.
  • Deadpan Snarker: More deadpan and less snarky than York, but it's still definitely there.
  • Face–Heel Turn: Forced into one when he is incorporated by the Meta.
  • Gentleman Snarker: Always polite, but always a snarker.
  • Good Is Not Soft: Suggests that Washington kill South after her Chronic Backstabbing Disorder becomes fully apparent.
  • In-Series Nickname: "D", especially by York.
  • Kick the Son of a Bitch: He coldly suggests to Washington "that we do not allow [South] to hamper our progress". But considering she had by this point betrayed her own brother, Wash, and Delta himself, it's hard to sympathize with the victim in question.
  • Ludicrous Precision: Has a habit of doing this at times with automatic unit conversion. Also, according to York in Season 10, he finds running probabilities in his head to be fun.
  • Mr. Exposition: Justified as he's made of logic and thus inclined to provide exposition.
  • Nice Guy: Though he does sometimes give York a hard time, he's even nice to his supposed enemies, unless they try to sell him out personally.
  • Not So Above It All: Despite being stoic, Delta is one who doesn't turn down the chance at revenge, opting to go after Wyoming despite the fact only his agent had been harmed by the former's previous actions. He also opts to kill South at the first possible opportunity after she had planned to betray him.
  • Not So Stoic: Has one of the "protocol violated alert" sort of moments when South ends up shooting Wash in the back.
  • Revenge: Surprisingly, he's a rather big fan of this.
  • The Spock: The Alpha's logic.
  • The Stoic: He's not based on emotion, but logic.
  • The Tape Knew You Would Say That: He left a recording for Church in Caboose's memories, using logic to predict Church's responses. Including his inanity in trying to test that.
    Church: Oh, reall-
    Delta: Yes, really.
    Church: Okay. I like cheeseburgers.
    Delta: Stop trying to test me.
    Church: Empire State Building.
    Delta: Seriously, stop.
  • Tin Man: For someone who's supposed to be pure emotionless logic, he's incredibly helpful, courteous, capable of great kindnesses, and even self-sacrifice for no other reason than to care for his dying owner. He's also one hell of a Gentleman Snarker.
  • Undying Loyalty: When York is mortally injured, Delta stays to administer painkillers until York dies instead of going with Tex, even though at the time he and Tex thought it would mean Delta's own erasure as well.
  • Unreliable Narrator: It is established that Delta is one of the few A.I. that can actually lie, and can skew information in his favor, both of these make it unsure how reliable a source of information Delta actually is.
  • Vitriolic Best Buds: He and York love to have snarky conversations with each other, but it's based out of affection and York's naturally snarky nature.
  • We Have Reserves: Like Lopez years later, he makes backup copies of himself in case of the death of those around him.
  • What the Hell, Hero?: 479er lays this on him for his Crazy-Prepared behavior right in front of her.
    Four Seven Niner: That's a dick move, green guy.
    Delta: I apologize if I have offended you.
    Four Seven Niner: Dick. Move.


Voiced By: Elijah Wood
Attribute: Creativity/Ambition

"Well, as the Director always says, it is important to have ambition."

Little was known about Sigma until he made his debut in Season 10, voiced by Elijah Wood (yes, that Elijah Wood). In the season, it is revealed that he was originally Carolina's AI partner, but was transferred to Maine after Maine had his throat shot out in Season 9 as a way of helping Maine communicate by being his voice for him. We also discover that he's the reason Maine eventually had a Face–Heel Turn, and that Sigma is responsible for most, if not all of the Meta's actions throughout The Recollection.

Associated Tropes:

  • Affably Evil: Seems to have a favorable relationship with Carolina prior to becoming Faux Affably Evil and causing the Meta incidents.
  • A.I. Is a Crapshoot: His ambition get really out of hand.
  • Ambition Is Evil: He's the personification of Alpha's creativity and ambition.
  • Arc Villain: He's retroactively revealed to be The Man Behind the Man for the Meta in Reconstruction, and is this during the Season 9 and 10 flashbacks,
  • Bald of Evil: Similar to Maine, the person whom he possess.
  • Become a Real Boy: His goal in life is to achieve metastability, which, to quote the Halo wikis, is the "theoretical fourth stage of rampancy, where an AI can finally be said to be a true 'person.'" However, given how he goes about achieving this, it's hard to feel sympathetic. Lampshaded by Aiden Price when asked about the Meta by Locus.
    Locus: When you said that Maine performed at his best when controlled by Sigma, then the Meta strove to be the perfect weapon.
    Price: You're mistaken in assuming Sigma's definition of "perfection". The Meta never wanted to be a weapon. The Meta wanted to be human.
  • Big Bad: Is this for Reconstructon as he is the one controlling the Meta and is reason for his attacks on the Freelancers and the AI stealing. Oddly enough, his status as this is only revealed long after his death.
  • Bond Breaker: Responsible for South betraying North. His manipulation of Carolina indirectly led to her fight with York.
  • The Chessmaster: Before he even get's his first line of screentime, he's already taking steps to achieving his goal of metastability. He was originally assigned to Carolina, but he manipulates her compassion and competitiveness so that she'll give him to Maine, a Freelancer who will be much easier to corrupt. Later Sigma and Gamma are shown persuading Carolina into using two AIs at once, which she plans to use on Tex, allowing Sigma to analyze and test the affects of having multiple A.I's in one body. They were most likely banking on Carolina being weak enough after the battle for Sigma to possess Maine and take her out, thus acquiring both of her A.I's at very little personal risk.
  • The Corrupter: He's the reason behind Maine becoming the Meta, thereby also making him indirectly responsible for the downfall of Project Freelancer itself.
  • Early-Bird Cameo: Can be seen and is killed in Reconstruction along with all of the other AIs that the Meta possessed, and is mentioned offhand by Washington as Alpha's "creativity" earlier.
  • Evil Is Burning Hot: His avatar looks like it's made of fire.
  • Evil Sounds Deep: Has a noticeable deeper undertone to everything he says.
  • Faux Affably Evil: Though he was originally just Affably Evil, his politeness with Carolina only makes it more horrifying when he attempts to murder her in cold blood.
  • Glowing Eyes of Doom: His eyes sure help with his Obviously Evil look.
  • Greater-Scope Villain: While he's only directly manipulating Big Bad in Reconstruction, he could also be considered this for Recreation and Revelation - while dead, his influence over the Meta remains. He's also responsible for Carolina receiving two AI fragments and losing her mind, Washington receiving Epsilon and losing his mind, South not receiving a fragment and betraying North, and the overall cause of the fall of Project Freelancer.
  • Ink-Suit Actor: Downplayed example, but the animation team explicitly said they modeled his face to resemble Elijah Wood's a little more.
  • Irony: Sigma pursued the concept of metastability, but the process of his actions eventually led to Epsilon becoming metastable instead of the Meta, according to Word of God. Sigma was also killed in the process. Doubly ironic in that each Greek letter in the Meta's symbol is associated with one of the fragments — but the letter Epsilon is not included.
  • Light Is Not Good: Has an orange avatar, but definitely not good.
  • The Man Behind the Man: To the Meta, whom he controlled.
  • Manipulative Bastard: Especially when working with Gamma.
  • Meaningful Name: His name could be a reference to mathematics, where the Greek letter Sigma represents the sum of an equation. The term "Meta" derives from Sigma's obsession with the fourth stage of AI Rampancy, Metastability, in which an AI can be considered fully sentient.
  • Mouth of Sauron: Subverted, in a sense. He was given to Maine by Carolina in order to let him still be able to communicate after his throat was damaged beyond repair, but recent information has let us know that it is really Sigma who is in charge, not Maine.
  • Non-Action Big Bad: While Sigma was behind everything Maine did as the Meta (at least up until the end of Reconstruction), he involves himself in combat and other direct physical actions much less than the other Freelancer A.I.s, even taking a break to "bad touch" Delta while Maine is busy fighting the Insurrectionist elites.
  • Obviously Evil: In addition to appearing as a man engulfed by flames with Glowing Eyes of Doom, Sigma speaks very ominously and notoriously ignores the A.I. protocols. Really, his rebelion should have came as no surprise.
  • Red Eyes, Take Warning: Has creepy red eyes and is behind the Meta.
  • Rule of Symbolism: In somewhat archaic Talmudic lore, the Metatron is a very high ranking angel, said to be second only to God himself, paralleling the Meta and it's nature in relation to the Alpha.
  • Start of Darkness: Seems to have been the AI coursework, where he learned and became curious about the Metastability stage.
  • Small Role, Big Impact: Sigma only physically appears in a handful of scenes of Season 10, but his actions, specifically his hold over Maine and his interest in metastability, not only kicks off the actions of the Meta, but the initial collapse of Project Freelancer that caused the Alpha to be relocated to Blood Gulch, where the series began.
  • Unnecessarily Creepy AI: Most AIs have holograms modeled on Mjolnir armor. His resembles a man on fire, and he has Voice of the Legion. It's like he was designed to be Obviously Evil.
  • Villain Team-Up: He and Gamma convinced Carolina to accept an AI. It's unclear how much Gamma knows about Sigma's plan to achieve metastability; and though they both mention Omega, there's no indication whether he's in on the plan as well, though he does help in the fracturing of the Alpha alongside them.
  • Voice of the Legion: It's not too noticeable, but it's a hint that he's no good.
  • Wham Line: In Episode 19 of Season 10, though the second half was stated out of context in the Season 10 teaser:
    Sigma: You run, Agent Texas. We are the Meta. And we will find you, very soon.
  • Wreathed in Flames: He certainly looks this way.

Attribute: Inner Child/Trust

Theta is North's AI, and represents the Alpha's trust, with a very shy and child-like demeanor and voice to match. Appearance-wise he looks like one of the standard armored soldiers similar to Delta, but done up in bright neon red and purple and with a higher range of movement. North seems to treat him like a proud daddy would treat his son.

Associated Tropes:

  • Adorkable: Slightly nervous around others, loves skateboarding virtually, outright adorable.
  • Attention Deficit... Ooh, Shiny!: Rather than pay attention during the AI class, he's playing around with a skateboard. Though to be fair, the class seems to be more for the Freelancers themselves.
  • Badass Adorable: Very capable of badass battle strategy and calculations. Very ridiculously cute.
  • Child Prodigy: A childlike AI who is also a Badass Adorable.
  • Children Are Innocent: He knows about the true nature of the AI fragments, but doesn't realize what it is.
  • Child Soldier: The darker, more disturbing flipside of Theta's Badass Adorable qualities. Most prominent in the episode of his introduction, Episode 5 of Season 10.
  • The Conscience: Epsilon's memory of Theta seems to serve as his conscience, urging him to apologize after he snaps at Tucker.
  • Creepy Child: Inverted. Theta is shy and lovable, which throws the utter creepiness of his origins into even sharper relief. Well, until he becomes part of the Meta. There was a creepy child voice quite prominent in Reconstruction speaking through Maine.
  • Early-Bird Cameo: Like Sigma above, Theta can be seen right out front with the other AI's the Meta had captured in reconstruction.
  • Embodiment of Virtue: Unlike the other AIs, which represent either a negative or a neutral trait, Theta embodies trust and shows it by being easily the nicest member of his "family".
  • The Klutz: Downplayed, but he is shown in episode 6 of season 10 having a hard time balancing on a holographic skateboard.
  • Shrinking Violet: Tries to hide behind North when being shown to Wash and the others. He only really speaks freely to Delta and North. He's also violet.
  • The Power of Trust: He is the manifestation of the Alpha's Trust.

    Eta and Iota 

Eta and Iota
Voiced By: Unknown
Attribute: Fear (Eta), Happiness (Iota)


Eta and Iota are the two AI fragments implanted in Agent Carolina. Eta and Iota were originally planned to be implanted in Agents South Dakota and Washington. They are also the first two AIs to be incorporated alongside Sigma to create the Meta.

Associated Tropes:

  • The Quiet Ones: Unlike other AIs, Eta and Iota only speak one line of dialogue in the series unless one counts them in Season 6.
  • Single-Minded Twins: They were applied to Carolina together, and so are only seen acting in tandem. Epsilon calls them "the twins" in his own versions of them in Season 12.
  • Synchronization: With each other, Carolina, the other fragments, and, apparently, the Director and the Sarcophagus. The movement of their avatars mirrors Carolina's when she's reeling in pain.
  • Unknown Character: Their implantation in Carolina ended up causing a whole host of problems for her, Wash, and South (and arguably Maine and Tex as well), collectively setting off the entire plot of the entire (non-flashback) series; and yet despite this plot significance, they have to date received only a single line and were killed off without any character interaction. Until the release of the guidebook, we didn't even know which one was which, or what their attributes were.


How well does it match the trope?
