The Nine Players
Voiced by: Kosuke Toriumi (JP), Troy Baker (EN)
An ordinary college student kidnapped from his car on Christmas Eve, and the protagonist of the game. He has a tendency to make risque jokes at inappropriate times and is easily swayed by his emotions, which makes him a poor choice for a game about trust and betrayal.
- Amnesiac Protagonist Catalyst: As part of the plan, he forgets that he's actually the Zero behind this Nonary Game.
- Artificial Limbs: Possesses a set of these due to the Mars mission test site incident. Unlike Snake's purely prosthetic arm from the first game, Sigma's limbs are fully functioning cybernetic replacements covered in synthetic tissue (which, sadly, means that the bracelet will work quite properly with them.)
- Big Damn Heroes: Does this in more than one timeline for both Alice and Quark, as they are the first to show symptoms of Radical-6 in almost every route.
- Butt-Monkey: In most bad endings when he receives 9 BP, he is NEVER allowed to leave. He is also the only player who is alive to see his BP drop below 0 in certain timelines. Taken to brutal heights in the bad ending on his path, where Dio, K, and Tenmyouji turn against him on suspicion of him being a robot, knock him unconscious, then cut off his hand to steal his bracelet.
- Can't Get Away with Nuthin': He is the only one who the others successfully prevent from leaving the facility by force.
- Chivalrous Pervert: He can get excessively creepy with the girls sometimes, but he definitely is one of the more compassionate of the cast.
- Determinator: He will not let anything stop him from his goal, which is particularly noticeable on the two paths where his bracelet is triggered. In each path, he manages to save at least one person's life and get some critical information while under the influence of a drug that knocks most people out instantly. And in the events prior to the game, he spent 45 years researching genetic engineering, quantum computing, artificial intelligence, and mechanical engineering to set up the Nonary Game, all with the purpose of undoing the outbreak of the Radical-6 virus.
- Dirty Old Man: Comes across as one to many of the other characters in game, thanks to him being literally a 22 year old in a 67 year old body.
- Failed a Spot Check: He never once realizes that he has a futuristic eyepatch in place of an eye, or that his voice has changed, or that with the exception of his arms he is a sixty-seven-year-old man. Justified in that the moon's gravity combined with the symptoms of Radical-6...along with many fogged up mirrors all over the place didn't tell him much.
- Failure Hero: The main objective of the game is to reverse this.
- First-Person Ghost: Aside from flashbacks, we never see his face. Nor do we get to hear his voice. This is intentional, in order to hide from the player his actual appearance, since it is a massive reveal.
- Freak Out:
- In his route, the Game Over that occurs if you find Alice dead ends with him screaming his lungs out followed by a fade to black and the narration "when I came to, I was floating in a field of nothingness". While this seems to imply his death, it is actually him jumping back in time due to the stress as seeing this bad ending is required to save Alice's life.
- A similar thing happens if you get the Game Over from betraying in his route's round 2.
- Go Mad from the Revelation: In his route's main Game Over, he wakes up in the infirmary to see his hand has been cut off and then he sees what his arm looks like as a cross-section. Cue the Freak Out.
- Handsome Lech: He has a muscular build and he's good looking enough, but for some reason, the girls in the game act with revulsion whenever he makes a pass at them. Subverted since Sigma spent the entire game possessing his 67 year old body with wild gray hair and a right green eyeglass.
- Heroic Build: He has some muscle on him, that's for sure. With his body being 67 years old (minus the artificial arms) it is remarkable his 22-year old mind doesn't notice any significant bodily aches or weaknesses.
- Heroic Sacrifice:
- Allows Dio to bring his BP to negative in exchange for the Axelavir needed to save Quark, though he survives the injection.
- In the K Path, Sigma uses the Neostigmine on Phi rather than himself.
- Honor Before Reason: In Dio's Game Over, Phi explicitly warns him that since her and Dio's opponent Luna is dead, there is nothing stopping them from picking betray, gaining 9 points, and leaving. Choosing to keep his promise to Clover and pick ally results in him being left to rot in the facility along with the other players.
- Kick the Dog: He can easily do this several times throughout the game. In fact, 7 of the 11 Game Overs are a direct result of him doing this, with 2 more having him on the receiving end.
- Life-or-Limb Decision: In Quark's ending, when his bracelet is triggered, Sigma uses the number 9 door as a giant cleaver to chop off his left arm in order to prevent it from giving him a fatal tubocurarine injection.
- Meaningful Name: It's not brought up in game, but Sigma is the mathematical symbol used in Summation: the adding together of many variations of an expression. Sigma goes through many iterations of the Nonary game and his experiences must be summed together to reach the solution.
- Noodle Incident:
- The one time he got really wasted and dated the mistress of a prominent politician. He swears it was her who came onto him.
- His Verbal Tic has a rather... strange origin that's surely even more unbelievable than the game itself.
- One Character, Multiple Lives: As a result of his ability to travel between timelines, he can essentially cheat death.
- Pungeon Master: Tends to crack some awful jokes, and is unable to prevent himself from making cat-related puns when they're brought up.
- Robotic Reveal: Played with in his ending. It turns out that Luna's suspicions about him being a robot are false, but he has cybernetic arms.
- Required Secondary Powers: He can leap between parallel timelines (which is the point of the entire Nonary Game), but he can only retain a portion of his memories during the jumps. What he does retain, however...
- The Reveal: The Sigma playing the Nonary Game is actually his 22-year-old consciousness inhabiting the body of his 67-year-old self. The purpose of the AB Project was to swap their minds, sending the mind of the older Sigma into the past so that he would have a chance to Set Right What Once Went Wrong.
- Save Scumming: He can jump between parallel worlds, and retains pieces of information from each jump. Unlike most video game examples, this ability is used as a plot device, and is lampshaded repeatedly by Sigma himself. It's later revealed to be an Esper ability. The goal of the Nonary game is to train and hone this ability so that he can jump back in time in order to prevent the Radical-6 outbreak.
- Taking You with Me: Discussed in Quark's ending when Sigma muses to himself that if Dio reneges on his promise to return medicine critical to saving Quark's life in exchange for an ally vote, Sigma intends to die with his hands around Dio's throat. Fortunately, it never comes to that.
- This Cannot Be!: When Alice betrays him and brings him to -1 BP in her Game Over, he can only respond with a dumbfounded "That's not possible...".
- Throw the Dog a Bone: He's allowed to leave with 9 BP in one ending other than the Golden Ending, specifically Dio's.
- Tomato in the Mirror: He is Zero (or more specifically, his future self whose body he's inhabiting is) and he doesn't know it until Phi's ending.
- Too Dumb to Live: With a mix of paranoia in Tenmyouji's first Game Over. Tenmyouji warns him that if he betrays him, Clover will have 9 BP and can escape. Three seconds after the two enter the voting room, Clover starts trying to seduce him into picking betray. If you agree, you deserve what you get.
- Unrequited Love Lasts Forever: Akane once told Kyle that Sigma was once in love with a woman when he was young. Zero Time Dilemma reveals this to be Diana, with the "unrequited" part only happening because of her early death.
- Verbal Tic: He has the rather goofy condition of making continuous cat puns whenever he thinks about cats. He cat stop it. Again, we're not kitten.
- Younger Than They Look: He is a 22-year old college student driving around the body of his 67-year old self.

A mysterious young girl who begins the Nonary Game as Sigma's first partner. She's quick-thinking, analytical, a smooth liar and knows things that she shouldn't be able to know.
- A-Cup Angst: When Sigma makes an offhanded joke about her chest, she protests that her size is C-Cup. Sigma doesn't buy that.
- Ad Hominem: Of the Tu Quoque variant. When Sigma asks whether she is working with Zero given that she inexplicably knows Sigma's name, she suddenly asks if Sigma is one of those behind the scenes, since he claimed to have premonitions. He tries to put the conversation back on track, but she stops him from doing so by saying "Don't change the subject. We're talking about you". The outcome of the exchange clears nothing about Sigma and Phi's knowledge about stuff they shouldn't be aware of, effectively preventing her from having to spill the beans.
- Big Eater: During the downtime before the next round that lasts at least 2 hours, she just went to the pantry and ate five meals. While this is made very slightly less ludicrous by the fact that everyone's perceiving time at approximately 1/2.45 the normal rate, that's still five meals in five hours or so.
- Deadpan Snarker: The snarkiest and most deadpan person in the trilogy of Zero Escape.
- Deuteragonist: She's Sigma's first and most constant companion, and she has just a big of a role in Zero's plan as Sigma does.
- Distinction Without a Difference: She resorts to it every time she tries to convince Sigma to vote "betray". Sigma feels compelled to do just that and wants to double-check with Phi, but then she claims she never recommended to betray: she will say something along the lines of "I presented the logical choice, but that's not the solution to every AB game", and will most likely blame Sigma if things turn out badly. Lampshaded by Sigma more than once. Specifically:Sigma: You made it pretty clear that we should choose "betray".
Phi: Well, I didn't say "should"... I just said we didn't really have a choice.
Sigma: That's the same thing.
Phi: It's completely different. The former is an active opinion. The latter is just passive information.
Sigma: Whatever. You still want to betray, right?
- Hard-Drinking Party Girl: Hinted at. Her mind's not exactly on solving the puzzles in the lounge full of exotic liquor. Not to mention her disdain for spilling out said cocktails.
- Hypocrite: At the very beginning of the game, she inexplicably knows your name and escapes justification by saying "I just knew". Much later on, when you log in to the computer in the director's office, she demands for explanation as to why you knew the ID and password. Guess what comes now? She angrily dismisses your "I just knew" reply by claiming that it has nothing to do with her knowing of Sigma's name, even when it's indeed the exact same thing.
- In a Single Bound: She frequently demonstrates superhuman jumping capabilities. At the end of her route, it is revealed that the source of her "powers" is the low gravitational pull of the Moon, where the game is actually set.
- Inexplicably Awesome: How does she know so much about quantum theory and game theory? Why is she so cool? She's certainly not going to tell you. Not even during the Omega Ending.
- Jerk with a Heart of Gold: In the beginning of the game she's cold and logical, telling Sigma to betray at every opportunity. However no matter what path, she's very compassionate, showing great concern for all of the characters (even Dio in some situations). In one path she even has the resolve to let herself die rather than enter the White Chromatic Doors without Tenmyouji, Clover, and Quark. She's also the only character who, having reached 9BP before anyone else, will stay and wait for the others instead of running for the exit.
- Malaproper: Every so often she butchers a common saying in an incredibly bizarre way, though pretty much everyone else does with "dunno" (spoken as "donno").
- Manipulative Bitch: Of the Spock-esque "You lied; I implied" variant, where she will use Exact Words and implications to manipulate people into doing what she wants while divorcing herself from culpability. An example is when she states to Sigma that the chance of an opponent choosing "Betray" is very high, but never actually recommends he choose "Betray" as a counter-move.
- The Not-Love Interest: She's the first girl Sigma meets, they initially have a belligerent relationship, her ending is the True Ending of the game, and she has a lot of plot relevance... but she and Sigma are never even hinted to move in a romantic direction. At best, they go from Teeth-Clenched Teamwork to something resembling friends. Although there are some scenes with them when you fail to defuse the bombs, they're not exceedingly romantic. Word of God confirms that Sigma and Phi will not be a couple at any point... which is explained in Zero Time Dilemma, as she is his Kid from the Future.
- One Character, Multiple Lives: Phi, much like Sigma, Akane and Junpei, retains most of her memories when she SHIFTs into parallel timelines.
- Pungeon Master: Usually as revenge for Sigma's own puns.
- The Reveal: She possesses the same psychic ability as Sigma (to jump her consciousness between different timelines/parallel worlds) but unlike him she cannot control how or when it happens. She was part of a failed attempt to prevent the release of the Radical-6 virus in the Nevada Test Site; afterwards, she brought herself to Akane and volunteered to be frozen for the Nonary Game to trigger a time loop and send her consciousness back even further in time. Her backstory, true identity and overall purpose in the grand chain of events is left intentionally vague, but she compares herself to a fractional deviation that is normally rounded away and forgotten, but would actually become significant over time.
- Save Scumming: Possesses the same power as Sigma.
- The Spock: Of the "Snarky Spock" sub-variety. She certainly has emotions but is rarely ruled by them.
- Sugar-and-Ice Personality: Phi alternates between the two at points.
- Thinking Tic: She rests her chin on her hand and stares off to the side.
- Unstuck in Time: Unlike Sigma, she has very little control over her jumps and is generally worse than him at remembering things across them. Since she's much smarter than Sigma, though, when she does remember her time-jumps, she's much more on the ball than him.
- Verbal Tic: She sometimes slips into rhyming slang when under pressure, like when she calls the key from the elevator puzzle safe a cracker.
Voiced by: Yoshimasa Hosoya (JP), Liam O'Brien (EN)
A man dressed as a circus ringleader. Though he styles himself as a smooth-talking charmer, he is quick to throw out accusations, take self-serving actions and sow discord amongst the group. Not to be confused with Dio Brando.
- Big Bad: He's not Zero, but he is the one sent to sabotage the mission to save the world and the one Zero is trying to stop.
- Big Bad Ensemble: With Zero III, who controls the game, though Dio is the primary physical threat to the players (what with his bombs and all).
- Big Bad Wannabe: He's the closest thing the game has to an on-screen Big Bad, but comes off as hapless considering the number of times he is tricked and subdued during many of the routes. Not to mention that he breaks under interrogation ridiculously quickly, and is so full of himself that he gives out the bomb deactivation codes when asked. Though of course he only does it when there is no way for you to stop him on that timeline. Little does he know that you can go back to the past.
- Call-Back: He indirectly quotes Ace from the last game, by saying that he likes fire in his women, and, like Ace, is the Big Bad holding the group hostage. However, Alice is no Damsel in Distress, unlike Lotus.
- Chronic Backstabbing Disorder: He almost never picks ally of his own volition.
- Circus Brat: You learn early on in some paths that Dio is a circus ringleader, fifth generation. This is, of course, just his cover story.
- Commander Contrarian: The first to complain about anything, and foul-mouthed to boot. It's not long before he gets on the nerves of absolutely everyone.
- Contrasting Sequel Antagonist: To Ace/Gentaro. Ace presented himself as a kind old man and was good at keeping up his Wise Old Folk Façade, and though he was a member of Free the Soul, his actions were meant to benefit himself only. Dio/Left is openly mean to everyone, makes it clear he is out for himself, is much younger than Ace, and is truly loyal to Brother and Free the Soul.
- Cyanide Pill: He swallows one in Alice's ending and attempts to do so in the Sigma and Phi endings.
- Dead Man's Switch: Has one that sets off his bombs if he drops it or it gets more than one meter from him.
- Deadpan Snarker: When faced with Clover's awful puns."... is it okay if I smack her?"
- The Dragon: He is the leader of the Myrmidons, the elite faction of Brother's terrorist cell.
- Driven to Suicide: If Sigma manages to expose his cover and restrain him, he will attempt to commit suicide by swallowing a cyanide pill before the others have the chance to interrogate him.
- Enemy Mine: In Phi's ending, Sigma theorizes that one of the reasons why everyone was finally able to trust one another enough to cooperate and reach enough BP to escape, together, was the bond they had developed while uniting to stop Dio's bombs.
- Expy: His design and general attitude and actions during the game closely resemble Yoshimitsu Tezuka from Secret Game: Killer Queen.
- Face of an Angel, Mind of a Demon: The only thing he's got going for him is just how neat he looks. Put him on "mute," don't listen to his words, and he looks like one cool dude. Listen to a word he says and the foulness seeps through.
- Hate Sink: Asshole, backstabber who will vote "betray" at every chance and murderer, ready to kill an old lady and blow up everyone in the facility to accomplish his goals. The game gives you exacly zero reasons to like him.
- Hostage Situation: One of the first ways that you can learn that Dio is an asshole, outside of the K/Dio endings, is to go down the Quark route — you will see him hold the Axelavir — the only thing that can save the ill Quark's life — hostage. Unless Sigma, who has 1 BP, picks Ally, he will destroy it. If you pick Ally, Sigma nearly dies and Dio escapes — if you pick Betray, Dio smashes the bottle and it is strongly implied that Quark dies.
- Hypocrite: Played With: The ideology of Dio's cult contradicts many of his actions and personality traits, as well as how he once "dirtied" himself through his activities with a woman.
- I Gave My Word: For all his other jerkassery if you vote ally against him after the laboratory he'll keep his promise and give you back the axelavir.
- Impaled with Extreme Prejudice: In Luna's Route, Dio axes K in the back of the head. Using the last of his strength, the latter retaliates by running Dio through with a spear.
- It's All About Me: Cares about no one but himself. Interestingly, this turns out to be a subversion, as the personality is meant as a cover for his true identity, which has no sense of individuality and his supposed self-interest was actually in the interest of furthering Brother's goals.
- Jerkass: He always, always picks "Betray" unless forced to or tricked into it by his partner. He'll have excuses a-plenty each time, but basically, the guy's just a jerk. There is one character that he votes Ally with: he allies with Luna if he's pitted against her in the first AB game, and apparently does so of his own will. When you consider the reason why he fell in disgrace with the Cult, that was probably even a genuine decision.
- Jerk with a Heart of Jerk: Everyone has a secret. Dio's secret is that he is a much bigger jerk than anyone could anticipate, as he is a murderous terrorist who leads an organization responsible for unleashing a deadly plague upon mankind.
- Just Between You and Me: He loves to gloat when he gets one over on another player. This leads to his downfall when he freely gives out the bomb deactivation codes in the different timelines as a way of taunting the other players. He gives out only one code each when confronted in his, Alice's, & Sigma's endings. In the route to Phi's (the True) route, he doesn't give any out, due to the fact that the input device had been found.
- Karmic Death: In K's Route. After being revealed as the murderer of the Mysterious Woman, he is confined into a treatment pod for security reasons. Later on, he's found dead as the oxygen supply is cut off.
- Me's a Crowd: Sort of. He considers his own death as not a big deal as he has backups, and the concept of individuality is kind of alien to him.
- The Mole: Although he thinks he is undiscovered, he is in reality being allowed to enter in as a mole for Brother.
- Nice Hat: He wears a top hat and claims to be a circus ringmaster. Word of God says that the detonator for the bombs is in it.
- Not Me This Time: You learn on K's route and on Dio's own route that Dio killed the old woman. On K's route, K also accuses Dio of killing both Luna and Alice. Dio swears that he killed the old woman and that's it, he doesn't know anything about Luna or Alice! As it turns out, when you play Luna's route, you learn that Dio was actually telling the truth: Clover (accidentally) killed Luna, and she never really died due to being a robot, and on most of the other routes you learn Alice killed herself, so Dio was telling the truth there too.
- Pet the Dog:
- There is one character who he votes Ally with: Luna. You can also find out that the reason he fell from grace within the Myrmidons was because he fell in love with a woman. Word of God states that he chooses Ally because he thought Luna was beautiful.
- According to promotional materials, he once saved a cat, though Word of God reminds us that this one act still doesn't make him a decent person.
- In Alice's game over, he is just as horrified as everyone else when Sigma runs out of BP.
- In all routes where he gets 9 BP and escapes, he's not the only one to do so. He always encourages whoever else has 9 BP to escape with him.
- Red Herring Mole: He's always the first to point fingers when things go wrong, and reliably chooses the "Betray" option whenever he's given the chance. The subversion comes when he really does turn out to be The Mole. He's so suspicious that the genre savvy player probably dismissed him as a Red Herring.
- Repulsive Ringmaster: Claims to be a circus ringleader, and proves to be the most self-serving member of the cast. He's really a terrorist ringleader, but he still dresses the part.
- The Reveal: His true identity is "Left", the leader of the terrorist organization "Myrmidons" and high-ranking cultist of "Free The Soul". Under orders from the cult's leader, he infiltrated the Nonary Game with the intention of stopping the AB Project. To do this, he must kill Akane Kurashiki and win the Nonary Game, or destroy the entire facility. He is actually a fourth-generation clone of the original "Left", and believes that by completing this "divine mission" he will attain sainthood.
- Sadistic Choice: In Quark's ending, he steals the axelavir needed to heal Quark back to health and threatens to destroy it if Sigma doesn't pick Ally in the following Ambidex Game. As Sigma currently sits at a single BP, Dio is basically tasking him with choosing between his own life and Quark's.
- Sir Swears-a-Lot: Need a Cluster F-Bomb or a Precision F-Strike? He's your man!Fun fact!
- Small Name, Big Ego: One of Dio's most notable traits is his overinflated ego.
- Smug Snake: He just loves to push buttons and stir up paranoia within the group as part of his tactic to win (as no-one else can gain points if they all choose "Betray"). The problem is that he's so blatantly untrustworthy that no-one in their right mind chooses to Ally with him, and his poker face falls apart very quickly when he is pushed into a corner.
- Social Darwinist: Even says as much in his ending.Dio: Why so serious? This really isn't the time for hesitation. You both crossed a line you weren't supposed to cross. You betrayed your friends. Am I right? I'm right. But you didn't have a choice, did you? You had to survive! Isn't that the way an animal thinks, though? Don't get me wrong, I see the logic, but it's kind of...animal logic. Still, you made your bed. Now you've gotta lie in it. If you're gonna be an animal, be an animal. Own it! The losers, the weak? Throw 'em away! That's how nature works, my friends—that's life at its most pure! You get me?
- Spree Killer:
- In Luna's route, Dio commits a series of murders in a very short time. He stabs the old woman, handcuffs Clover and Tenmyouji to guarantee the two will suffer the bracelet's penalty and mortally wounds K with an axe before finally facing his own doom.
- In the cyan door routes, Dio is responsible for the deaths of all players, as his antimatter bombs destroy the entire facility.
- Taking You with Me: As a clone and a zealot, Dio acts nonchalant over the idea of blowing himself up so that his mission succeeds.
- Token Evil Teammate: He is the most malicious person in your group of players this time around.
- That Liar Lies: Upon meeting the gang, K declares that he has amnesia and can't remember a thing about himself, not even his name. Dio doesn't buy that and outright calls him out on the "obvious" lie. Turns out he was wrong and K really had amnesia (in timelines where it really is Kyle in the suit, at least).
- Tyke-Bomb: Not just Dio, but all Myrmidons are clones of Brother's brother Left, and are raised from creation to become Myrmidons under Free The Soul.
- Unwitting Pawn: He thinks he's the Spanner in the Works that will screw over Akane's plans, but in reality he's just dancing to her fiddle- and Brother's fiddle, as Zero Time Dilemma reveals.
- What Happened to the Mouse?: In the game's true ending, Dio is still handcuffed and is periodically injected with Soporil to prevent him from awakening. Whatever Sigma and Akane intend to do with him is still unclear.

A large man wearing a robotic bodysuit that completely conceals his identity. He is suffering from amnesia and only remembers his name as "K". He is incredibly polite, but chooses his options during the Ambidex Game with the cold precision of a machine.
- Artificial Human: He's a clone of Sigma.
- Chronic Backstabbing Disorder: He generally defaults to picking betray. However, unlike Dio, he does have standards; he will never commit murder through voting, he will never betray the comatose Quark, and he can be convinced to ally with Phi when she puts herself in a situation where a successful betrayal would hurt her.Details
- Clingy Costume: The armour is "locked" onto K, and he cannot remove it without the key.
- Easily Forgiven: In his path, he promises Sigma he's going to vote ally against him in the AB game, and also that even if he did betray to get 9 points he wouldn't escape without the other players. If Sigma votes ally, K betrays and escapes, admitting that he flat out lied to get out of the game. If Sigma votes betray, both player calmly acknowledge the other's attempt to trick them, admit that neither has any right to be upset given they voted betray as well, and they go on working together immediately with no hard feelings.
- Everyone Has Standards: He'll refuse to kill anyone through votes, even if it ensures his escape. Similarly, he won't betray the comatose Quark even if it's easy points.
- Expressive Mask: The eyes on his mask change to reflect his emotions.
- Gentle Giant: Subverted. He is rather amiable and rarely loses his composure, but just like the others he can be devious and dishonest at times. He's also willing to use violence to get his way, especially when making a vote.
- Hands-Off Parenting: A victim of this. His "father", Sigma, never really spent time with him as a child. Once K started showing interest in Sigma's work, their bond got better.
- Honor Before Reason: Subverted in Quark's ending; he vocalizes a desire to remain in the facility with a dying Sigma even though he has 9 BP, but changes his mind when Sigma points out that they can't trust Dio to call for help.
- I Lied: The only time Sigma confronts K in the AB game, the latter asks him to choose "ally" so both of them can gain 2 points. Sigma would like to do just that, but he wonders aloud if K won't betray him and get the 3 points he needs to open the number nine door and escape. K tells him that, even if he reached 9 BP by betraying him, he would not escape. So he indeed does pick "betray" and, much to the surprise of Sigma, K breaks his promise and gets out of the facility. He never explicitly says "I lied", but he pretty much admits he did by acknowledging he took advantage of Sigma's trust.
- Manchild: He doesn't seem to find anything wrong with a grown man on a Zero III kiddie ride in the REC room, to Sigma's and Alice's horror. Justified, since he was a lab experiment all of childhood and apparently never learnt much of the outside world.
- Manipulative Bastard: In his bad ending he tricks Sigma into picking "ally", and then betrays him both in voting and by breaking his promise not to leave.
- Meaningful Name: K can be taken one of two ways - from the first and last name of Kyle Klim, or from Akane Kurashiki's last name, as well as her nickname "Kanny".
- Powered Armor: Because of this, the mechanism that locks or unlocks his armour fails to function if the armour is broken or powered-down. It's also an inversion of the usual purpose of Powered Armour, which is to increase the natural strength of the wielder. Instead, K's armour acts as a massive training weight that will subject his body to forces equivalent to Earth-like gravitational conditions, ensuring that he does not grow up with a frail body.
- Red Herring: If you look at the mass suicide depicted in the Clover ending, you might notice that K is missing, and suspect he is the killer. But in reality, K was not complicit in the deaths, and had probably just been looking for a way to remove his armor so he could join them.
- The Reveal: The matter of K's identity is a case of Schrodinger's Cat. The first choice Sigma makes is whether to go into the Yellow, Magenta or Cyan doors:
- In the Yellow and Magenta routes, his true identity is Kyle Klim, the younger clone of Dr. Sigma Klim. Having been "born" and raised on the Moon, his armour is designed to subject his body to the equivalent of Earth-like gravity and ensure that he would not grow up frail. His purpose is to act as Zero's back-up, with his consciousness being sent back to 2028 if his father failed. His amnesia was intentionally induced with a high dose of Soparil to revert him to a blank slate for the Nonary Game.
- In the Cyan route, which is what leads up to the true ending, the armor is instead inhabited by Akane Kurashiki for the duration of the game, with Kyle in cold sleep in the 00 treatment pod in the B. Garden (with Akane using the phenomenon "Schrodinger's Cat" to change the past from in the future, and pretending to be Kyle to preserve the events of the original timelines).
- Revenge Before Reason: In K's Route, he murders Dio by cutting off the oxygen supply in his treatment pod over the death of the Mysterious Woman...who was a surrogate mother to K in his childhood. This results in Dio's bracelet being broken during his death throes, and thus leaving both K and Phi unable to proceed with the Nonary Game without being penalised. Word of God also states that Dio's bracelet was actually broken by K, and that he did so on a gamble to test his father's love: If Sigma got the antidote, would he save either him or Phi? (Unfortunately for him, he forgot that his father's body was inhabited by his 22-year old consciousness and had no idea how to get K's armor off.)
- Samus Is a Girl: In the Cyan route, the K armor is occupied by the female Akane Kurashiki. Averted in the Yellow and Magenta routes, where the armor is instead occupied by Sigma's clone Kyle.
- The Spock: His polite, formal and dispassionate way of speaking makes him easily mistaken for an actual robot.
- Taking You with Me: In Luna's route, when Dio murders him offscreen, he manages to retaliate and kill Dio before succumbing to his own wounds.
- Thou Shalt Not Kill: He is generally willing to pick betray to save himself, but betraying someone with less than 3 BP is a line he absolutely will not cross.
- You're Insane!: While he doesn't express this sentiment to Zero Sr.'s face (as far as anyone knows), he nevertheless makes remarks to this effect when theorizing why they might have murdered Alice on Luna's route.K: Zero Sr. seems to be rather...disturbed.

A young pacifist who just wants everyone to get along so that they can all escape together. Her medical license and expertise prove invaluable during the Nonary Game, but she is vague on what her exact discipline is.
- Accomplice by Inaction: Luna considers herself this; Akane ordered her not to reveal what she knows about the Nonary Game or its players. She is programmed to die if she disobeys orders."I watched six people die and did nothing. I deserve this."
- Actual Pacifist: Luna never picks "Betray", because it isn't in her nature.
- Animal Motifs: Bluebird of Happiness.
- Beware the Nice Ones: She can be very vengeful if Sigma chooses betray against her. The latter of the two game overs on her path involves her getting Quark to safety while leaving everyone else trapped in the warehouse forever (in the former game over, Tenmyouji's the one who gets Quark out instead, with Luna's whereabouts unknown).
- Cute Machines: She's a very realistic android, and is fairly attractive.
- Luna is this series equivalent to one Sora. Both having similar dilemmas.
- In an interesting case, Luna herself is purposely designed to be an Expy In-Universe as she's based on Diana from Zero Time Dilemma. Because of the order of the games' release however, Diana is considered the Expy of Luna while chronologically in game, it's the other way around.
- Facial Horror: The artificial skin of Luna's face degenerates as she dies in Sigma's arms in her character ending.
- Faking the Dead: She can't actually die due to being a robot, but Zero III forcibly shuts her off in situations where others perceive her to be dead.
- Fantastic Racism: One of the reasons the cast turn on Luna during her ending. It's hard to trust a robot, especially when that robot has been concealing what they are.
- The Fettered: Akane deliberately limited her knowledge of the Nonary Game to make the project's success more likely.
- The Four Loves: It's not a secret she's in love with Sigma, both his innocent 22-year-old consciousness, and his true older self. She was in part created to act as a mother for Kyle, but was rejected for being a GAULEM. She was the only one who stuck around the Infirmary to care for Kyle after he was unfrozen from the Treatment Pod, which might indicate that she still has motherly feelings towards him.
- Iconic Item: Her necklace, which originally belonged to Diana, and which Sigma gave to her after Diana's death. It's appropriately symbolic: close examination shows that the cage has no door.
- Heroic BSoD: Has one in her bad ending, after Sigma betrays her."Sigma...why? Y- you promised...How could you? Why won't you say something? At least give me an excuse! Say...say you wanted to protect everybody...or you slipped and hit the wrong button! Anything! I don't care if it's a lie. Just...just say something..."
- Just a Machine: When presented to a young Kyle after he asked Dr. Klim for a mother, the child refused to acknowledge her as he saw her as just a robot who couldn't really feel. He interpreted her genuine feelings of sadness as "just clever programming".
- Mind Screwdriver: Luna's route clears up a lot of confusion on the other routes. For example, in the timelines in which Quark doesn't actively try to kill himself, Quark mysteriously "disappears" and sometimes is never seen again. It turns out this is because Luna's the one who carried an unconscious Quark to the "treatment center" and put Quark in one of the pods after Zero Jr. unlocked the treatment center. For another example, in many of the timelines, Alice kills herself due to Radical-6, but on some of those timelines you also find Luna's body next to Alice's. The obvious suspect is Dio, but you learn on K's route that Dio didn't kill either Luna or Alice. Alice killed herself, so who killed Luna? On Luna's route, you learn it was Clover, although it turns out it was an accident since Clover had only intended to "threaten" Luna into confessing to Alice's murder.
- Keigo: A lot of her speech patterns in the Japanese version fall into this. Justified somewhat given her nature.
- Meido: A concept sketch in the artbook shows her as one. Her actual occupation is left ambiguous, though- Akane treats her existence as highly important to her plan (ordering Sigma to learn robotics so he can create her) but why is not revealed.
- Mr. Exposition: In the ending of her route, Luna explains at length the many illogical events that occurred in it, and her dying words foreshadow Sigma's true identity.
- Nice Girl: Her benevolent demeanor unfortunately serves as a Red Herring, leading many players to believe that she is putting on an act and will "betray" anyone at the right moment. In fact, throughout the game, she betrays her AB game opponents all of 0 times.
- Not Quite Dead: She is found with a tubocurarine injection in several routes, and is presumed dead. However, since she's actually a robot, she's only faking it, and this is made clear in her ending.
- Replacement Goldfish: Although it's never directly brought up within the game itself, a passing comment in K's ending along with some answers to fan questions from Uchikoshinote heavily implies Luna was modeled on a woman Zero Sr. (aka Sigma) had loved. Zero Time Dilemma confirms it, as the woman (Diana) died from an illness and Sigma created Luna to fill the void. While Luna never admits if she knows she's based on her creator's lost love, the fact that she's thinks of herself as just 'a jumble of metal and plastic pretending to be real' hints she might be all too aware of it.
- Red Herring: In Luna's route, the poor girl gets hit with this three times. First, because of circumstantial evidence discovered by one of the AB booths, which has been moved by a crane, Luna is suspected of having killed the old woman (actually, it was Dio). Second, Clover mistakenly thinks Luna murdered Alice to keep her quiet (actually Alice killed herself after being infected with Radical-6), so Clover accidentally injects Luna with tubocurarine during a struggle, which incidentally is why you find Luna's body next to Alice's in a bunch of timelines. Third, eventually Clover and Tenmyouji turn up dead, handcuffed to a sink so they can't enter the doors and would get penalized, and Dio and K also turn up dead, killed by medieval weapons. Since only Sigma, Phi, and Luna (a GAULEM can't be killed by tubocurarine) are alive now, and since "dio" gets mistaken for "016" (Luna's ID number), Luna is suspected of having killed everyone (it turns out Dio killed them all, but finally K managed to kill Dio in self-defense before K died).
- The Reveal: Luna is actually GTF-DM-L-016, a semi-autonomous gynoid called a GAULEM used to support the functions of Rhizome 9. She was specifically tasked by Akane Kurashiki to observe and support the Nonary Game. Her pacifistic nature is due to her being encoded with the Three Laws of Robotics, which prevents her from causing harm to any of the human players. (Though unbeknownst to her, she has also been encoded with the Zeroth Law so that the necessary deaths in the AB Project would not cause her to shut down.)
- Ridiculously Human Robot: Despite being a robot, Luna's probably one of the more human characters.
- Solemn Ending Theme: Blue Bird's Lamentation.
- Suspiciously Similar Substitute: She looks and behaves very similar to June from the game's predecessor, except unlike June, Luna is not secretly the quasi-evil mastermind who set up the current Nonary Game. Which isn't surprising, considering one of her programmers is Akane herself.
- Team Mom: Considering she also has a medical license... She was also the GAULEM that Sigma created when K asked for a mother, though Word of God says that K only interpreted it that way and that Luna was not created just to give K a mother.
- Three Laws-Compliant: Discussed and ultimately subverted: the reason why she feels like an Accomplice by Inaction to all the murders that happen in her route is because she obeyed Akane's orders, as the 2nd law dictates. However, Akane's orders involve allowing human beings to come to harm, going against the 1st law - if she were truly three laws compliant, then she would have been justified in ignoring her orders. She eventually does disobey some of Akane's instructions, causing her to die - but her ability to do this makes her feel that she could have saved the others, leading to her guilt. Her behaviour makes more sense if you consider the Zeroth Law, and how Akane's orders are justified as being for the greater good (also throwing in the 3rd law for good measure).
- Walking Spoiler: Luna's ending, where she reveals herself to be a GAULEM and sheds some light into the nature and purpose of the Ambidex game, offers some of the biggest twists in the plot, second only to Phi's ending.

A precocious young boy with a sharp mind. He seems to have a strong attachment to Tenmyouji.
- Censored Child Death: Despite the several Kill 'Em All endings, Quark never has an onscreen death, with most endings simply implying he dies or having him missing. He is the one to get out most times along with Clover in the Bad Endings, since almost no one would be evil enough to put a child's life at risk.
- Children Are Innocent: Played straight, despite several instances where the characters will lampshade the possibility that Quark is Zero Sr. and that the player themselves might suspect them on the sheer unlikelihood of that happening, Quark is even more sweet than what he seems, even in the end where Tenmyouji gets them and Clover out of the Rhizome-9, Quark is nice enough to give Sigma a letter explaining their reasoning and attempting to apologize for his grandfather's actions.
- Driven to Suicide: Like most people who contract Radical-6. He is fortunately stopped from killing himself no matter the scenario.
- Happily Adopted: Tenmyouji found him as a baby and raised him to be his own grandson. The two of them love each other deeply.
- Harmful to Minors: Several people think better of doing bad things because they don't want to mentally scar Quark. Unfortunately, in several scenarios, Quark is exposed to trauma, regardless.
- Ill Boy: He suffers from Radical-6 and is at risk of commiting suicide unless he is treated.
- Large Ham: When he's in the infirmary suffering from the worst effects of Radical-6.
- Morality Pet: He's the one character that the others hesitate or outright refuse to screw over. The exceptions are Dio and potentially Sigma.
- My God, What Have I Done?: In his backstory, as you learn from a letter Quark gives to you in Tenmyouji's ending. A while after Quark was adopted by Tenmyouji, after their grandfather-grandson relationship was previously nothing but loving, Quark had a really bad day and, as a result, gave Tenmyouji useless garbage instead of useful salvage. When Tenmyouji scolded him for it, Quark ended up yelling at Tenmyouji and it turned into a huge fight, culminating in Quark running away from home. Quark ended up hiding out in an abandoned building during a rainstorm, and Tenmyouji still searched high and low for him even in the pouring rain. After Tenmyouji finally found Quark, Tenmyouji got horribly sick and had to be rushed to the hospital. Quark felt terrible, realizing that he had completely misread Tenmyouji's intentions. When Tenmyouji did finally pull through, Quark apologized and asked Tenmyouji if this made Tenmyouji regret ever adopting Quark. Tenmyouji's response was a surprised, "Of course not!"
- Out of Focus: Disappears from the story on the routes beyond the magenta door, due to being rendered unconscious because of Radical-6 and put into stasis. Averted on the routes where he is cured.
- Nice Hat: Supposedly, he stores snacks in there.
- Parental Abandonment: Never really addressed, but likely as a result of Radical-6.
- Red Herring: It's easy to suspect him, since the first game made was known for making the most innocent looking character turn out to be the Big Bad, combined with Dio swearing that Quark was the one that told him to betray everyone and later moments where everyone thinks Quark does indeed have the opportunity to be Zero Sr., it's easy to think that Quark is some sort of secret evil mastermind that is pulling the strings of the game, however he is actually very sweet and naive, doesn't even know the mastermind and spends most of the time of the game either passed out or missing.
- The Reveal: Quark is actually Tenmyouji's adoptive grandson, whom he found as a baby. He willingly came to Rhizome 9 with his grandfather, and thus has been threatened by Zero with Tenmyouji's death if he should reveal any of the actual nature of Rhizome 9 and the current state of the world to the other players before the end of the Nonary Game.
- Tagalong Kid: He's the only one out of the cast that wasn't kidnapped for a specific reason; he was brought along by Tenmyouji and thus ended up being dragged into the game.
- You Have to Believe Me!: When Dio and Quark's vote turns out to be "Betray" early in the game, if their opponent is Tenmyouji, Dio attempts to persuade Tenmyouji that Quark pushed the button, while Quark responds by screaming that Dio pushed the button and begging for Tenmyouji to believe him. (This trope turns out better than usual, though: Tenmyouji scolds Quark for losing his temper, but ultimately does believe Quark because he's known Quark for a while and could be deaf and blind and would still know if Quark was lying to him.)

A sharp-tempered old man who describes his profession as "garbage collector", yet possesses insight into a number of scientific principles and theories. He is slow to trust others, but has a special fondness for Quark.
- Berserk Button: Do not threaten Quark.
- Chronic Backstabbing Disorder: With the exception of Quark and Clover, everybody's fair game to him.
- Cool Old Guy: He is perfectly capable of knocking people a third of his age flat on their asses.
- Determinator: All that Tenmyouji cares about is saving Quark, everything else takes a back seat. Goes so far as to betray you and strand everyone in his ending. Junpei hasn't changed at all - whether it's Akane or Quark, the people he cares about take priority over all else. This is also how he feels about the state of post-apocalyptic humanity. He is against Akane and Dr. Klim's actions in reversing the past, beacause he as well as many others still living on earth have made lives for themselves in the midst of the apocalypse. He does not want to lose his current life, because even though survival has been difficult, he has accomplished something worthwhile: finding and raising Quark."Isn't that worth something? Isn't that the best thing humans can aspire to? Is there really any point to a world where everything is happy? Are people who struggle for a better life just idiots? Being human is about fighting even when it seems hopeless, and finding happiness even in a world that hates it."
- Dirty Old Man: He seems excited when he sees a poster of a woman in a bikini. Doesn't seem to bother Quark though, especially since he knows that Tenmyouji has a cabinet full of 'Grandpa' videos!
- Disaster Scavengers: As Quark's letter reveals, he is one.
- Exact Words: In his ending, he promises Sigma he won't open the number 9 door even if he gets to 9 BP. He keeps that promise... but only because he expected Clover to open it, proceeding to escape with Quark alongside her. He also points out that he has 11 BP instead of 9 when getting grilled over it.
- Grumpy Old Man: His grumpiness is a lot more understandable once you hear about his past.
- Heroic BSoD: He has a nasty one when you discover the old woman's corpse in some of the routes. Looks like he found Akane, all right.
- Hero of Another Story: He is the original hero, Junpei, from Nine Hours, Nine Persons, Nine Doors.
- Heroic Sacrifice: On one route, where an unconscious Quark gets 9 BP, he carries Quark out through the number 9 door, knowing full well that he'll die for not having 9 BP.
- Hidden Depths: This is Junpei, the person we hardly know about previously, yet here it's implied that he has a basic understanding of quantum physics and was involved with the Mars simulation site somehow.
- Honor Before Reason: He feels timelines which result in extreme tragedy — as in the one he lives during the events of the game — are just as meaningful as golden endings and looks down on notions that only those happy endings are worth preserving.
- Hypocrite: He calls out on Sigma for betraying Luna in her bad ending... when Tenmyouji had done just the same to Clover, before making his escape with Quark who has 9 points.
- Jerk with a Heart of Gold: Particularly emphasized during his path. He betrays Sigma in round one of the AB game to put him on death's door, and doesn't seem to feel too bad about it, emphasizing that he only cares about getting Quark out of the game. He at one point threatens to betray him again in round two, which could kill Sigma, just because he's annoying him with questions about the outside world. He then betrays Sigma in round three after tricking Sigma into believing he wouldn't, and then escapes with Clover, even mocking Sigma's trust on the way out. Quark gives Sigma a letter he wrote, detailing how he and Tenmyouji came to know each other, how Tenmyouji had been a loving and caring adoptive grandfather, and what an upstanding guy Tenmyouji actually is despite his selfish actions in the nonary game. At the end of the game you find out that Tenmyouji's round three betrayal was prompted by finding out Sigma is Zero, which makes it all slightly more reasonable.
- Last-Name Basis: Used deliberately, to avoid spoiling that his first name is Junpei.
- Loving a Shadow: Deconstructed. Essentially why he chased Akane for so long. This devotion destroys his life, and when he jumps at the chance to meet her again, he puts both his grandson's and his own life at stake. In the "End & Beginning" epilogue, he finally acknowledges (to his deep sadness) that the innocent Akane he once knew no longer exists.
- Meaningful Name:
- 'Ten' means "sky, heaven or space", 'Myou' means "bright" which is made from the words "sun" and "moon", 'Ji' means "temple", but temple can also be read as 'tera' which sounds like "terra" which is Latin for "earth". What you have is the heavens, sun, moon and earth; in other words, an eclipse.
- His name also has a reasonably meaningful implication in English, one that may not have been intended: that is, (Ten)myouji, for someone who has already surpassed a Nonary Game.
- Previous Player-Character Cameo: He's actually the protagonist of the previous game. Since you're initially led to believe the game takes place only a year after the first, the revelation is surprising.
- The Reveal: His true identity is Junpei, the protagonist of Nine Hours, Nine Persons, Nine Doors who escaped the second Nonary Game and dedicated his life to finding Akane Kurashiki, his first true love. After the nuclear winter caused by Radical-6, he became a scavenger and handyman, eventually adopting a young infant called Quark as his own grandson. He willingly came to Rhizome 9 after Zero promised to let him meet Akane, and has been threatened into silence about the current state of the world.
- Ship Sinking: Akane's actions have caused Junpei's feelings for her after all of these time to sour like milk, instead of age like wine. At least in that bad future."The Akane Kurashiki I knew isn't here. She isn't anywhere..."
- That Man Is Dead: Concludes that the Akane he grew up with is gone, and compares what's left to a Humanoid Abomination.
- Used to Be a Sweet Kid: After all those years searching for Akane never gave him results, he eventually turned into an apathetic old man whose only redeeming value is trusting his close friends. When he got word he could see Akane again, only to put Quark in the risk of death in her second Nonary Game, by that point he was through with her and doesn't care about her, believing the Akane he knew was no more.
- Undying Loyalty: To Quark, and to an extent, Clover. It makes perfect sense when you learn that he's Junpei. In one ending, he decides to leave the Number 9 Room with an unconscious Quark with 9 BP, despite his own insufficient BP, because there's a murderer running about. He knows he'll die, but he doesn't care. He'd rather face death than let Quark wake up alone.

A scantily-clad girl who first appeared in Nine Hours, Nine Persons, Nine Doors. Though cheerful and light-hearted, she isn't the sharpest tool in the shed and is prone to rapid swings of emotion. She is close friends with Alice.
- Accidental Murder: In several timelines, you find Luna's body next to Alice's. Clover believed that Luna murdered Alice and intended to threaten her into confessing, and accidentally injected Luna with tubocurarine during a struggle. In actuality, Alice killed herself due to Radical-6 infection.
- Ax-Crazy: Subverted. Unlike the game's predecessor, Clover doesn't go on a murderous rampage, though she does threaten to do so.
- Bare Your Midriff: Clover's crop top and short shorts leave a lot of space to show her belly.
- Butt-Monkey: After everything she went through prior to and during 999, she's now been cryogenically frozen and sent 45 years into the future without her knowledge, made to accidentally "murder" someone in one timeline, and her "good ending" ends with a Kill 'Em All.
- Exact Words: Combined with a bit of The Schlub Pub Seduction Deduction. She pulls it off on Sigma in one route. She promises to "listen to whatever he says" if he chooses Betray. If he does, she gets 9 (he doesn't) and leaves, all while listening to whatever he says, but not doing any of it.
- Giving Someone the Pointer Finger: And with the same pose as last game.
- Hotter and Sexier: First off, she looks much older here than in 999 (in a good sense, because she looked like a kid back then). Secondly, she wears very little clothing that fully exposes her belly and part of her thighs. Her bra (or similar) is visible. And she has very flirty poses (and uses them on occasion to her advantage).
- Immediate Self-Contradiction: At one point, Tenmyouji foresees that Clover will try and seduce Sigma so he betrays Tenmyouji in the AB game. She seems disgusted from the mere idea of seducing an old man like Sigma, and says there's no way on earth she would do that. Moments later, upon entering the AB room, she outright makes a horny proposal to Sigma.
- Leaves everyone behind to escape in both Tenmyouji's bad endings. Although to be fair, one of those times (specifically, Tenmyouji Game Over #1) isn't Clover's fault: in a flashback we learn that Alice gave Clover a direct order as her commanding officer to escape so she can call for help for the rest of them.
- She initially considers and persuades Sigma to betray a comatose Quark during her own path. Granted, she changes her mind at the last minute when it's time to vote, but before then she didn't seem to find anything wrong with taking advantage of a comatose kid, even if she had believed that there wouldn't be another AB game since other players may have 9 BP and would try to leave the warehouse, and Sigma and Clover would need to get 9 BP first before that happened.
- Ms. Fanservice: Although not as much as Alice, she is quite pleasantly dressed.
- Perpetual Smiler: Her neutral pose has her grinning. Possibly due to a glitch in the game, whenever Clover stops talking while in her worried/sad/surprised pose, she defaults to her smiling expression, making intense moments off.
- Pink Means Feminine: Her pink was made lighter compared to 999, to an extent where it's difficult to chalk up to better graphics.
- Roaring Rampage of Revenge: Threatens to do this in Tenmyouji's route if the others can't prove Alice wasn't murdered.
- Psychic Link: Carrying over from 999, she claims to have one with her brother via the morphogenetic field. Unfortunately, it doesn't appear to be working in this warehouse. She mentions that may be because stronger Espers block out her power. And considering how the cast consists of Akane, Junpei, Phi and Sigma, you can't blame the poor girl. Though the fact that she's apparently been in a deep freeze for 45 years while two apocalypses happened could also have something to do with it — Light might not even be around anymore.
- Red Herring: Especially for those players who played the first game and remember what happened in the Axe Ending. Though the game teases the possibility of Clover snapping again following Alice's death, the only death she was involved in (aside from her own) was an accident - and due to circumstances it wasn't actually a real murder.
- The Reveal: She works with Alice for the Department of Defense, undergoing training to strengthen her psychic abilities. On the eve that they were set to attack a terrorist cell belonging to the Myrmidons, both she and Alice were kidnapped by Zero and placed into cryogenic stasis so they could be revived in the future for the Nonary Game. As Espers gain more power in proximity to each other, Clover was taken so that her presence would strength the psychic abilities of Sigma and Phi.
- Rose-Haired Sweetie: Although less rosy, and more pinkish, compared to 999.
- Stripperific: It seems that she's taking tips from Alice's fashion sense. On a more serious note addressed in the Q&A, however, she dresses so peculiarly because it makes it harder for people outside her organization to truly believe she's part of a secret organization at all. This is also the same reason why Alice wears Vapor Wear.
- Who Wears Short Shorts?: Part of her Ms. Fanservice getup.
- Took a Level in Badass: Zigzagged. While, in theory, she's gotten stronger with her psychic powers and combat training, both government missions she was sent on were failures, and her psychic powers are useless thanks to other issues. On the other hand, Clover has gotten a LOT better at lying, and she teams up with Alice to thoroughly beat down Dio in one of the endings.
- Wonder Twin Powers: She's honed her ability to use the morphogenetic field, and now can easily send Light messages at will.

An enigmatic, exotic woman who seems to be a close acquaintance of Clover. A popular rumour is that the water that composes her body is Ice-9, an polymorph of water whose freezing point is just around 36°C (96°F).
- Action Girl: She's no doubt, an experienced martial artist after she became a field agent for SOIS when Dio reveals himself as Left, the leader of the Myrmidons, pulling out the detonator to blow up the place. She and Clover teamed up to retrieve the detonator with Clover distracting Dio and Alice giving the finishing touch by grappling Dio to the floor and throwing it to Sigma.
- Bare Your Midriff: She wears so little clothing that this becomes Bare Your Entire Torso. Though the focus is usually not the midriff but two round huge things just above it.
- Black Girl Dies First: Alice dies first in all routes except hers and the golden route and she still dies in her route. But then, so does everyone considering the bunker blows up.
- Butt-Monkey: In in the first AB Game, except for her route path, she is always betrayed, thus causing her BP to fall to 1 quite often. Not only that, she always succumbs to Radical-6 and is found dead in the Crew Quarters in most timelines before the second AB Game starts. Her bad luck in the game is exemplified in Clover's path where she is forced to compete against Dio three times in a row, ensuing that her BP will remain 1.
- Cool Big Sis: Though they are not related, Clover sees Alice as this.
- Driven to Suicide: She begins showing signs of Radical-6 infection about halfway through. Whether or not she goes through with the suicide depends on the timeline.
- Everyone Has Standards: Has no qualms with betraying Sigma and potentially killing him due to him having one BP point left in her route, though she does eventually express remorse later on after being confronted for her decision. However, she does not approve of betraying a comatose child, even in situations where her own BP is 1 point away from death and would really benefit with extra points to protect herself from dying, and is openly disgusted at Sigma, who takes the chance to betray Quark for the sole purpose of escaping right there and then.
- Everyone Looks Sexier If French: French mother, Egyptian father. She seems completely unfazed by the idea of people mistaking her for a legendarily beautiful Egpytian queen.
- Gag Boobs: Her breasts are so huge that Dio makes an offhand joke about them when the gang reunites in front of the elevator after you explore the Lounge:Sigma: What's going on here?
Alice: We ran into them a little bit ago. Well, not literally, of course.
Dio: I donno... With a prow like that, I imagine you run into a lot of things.
- Good with Numbers: She can do complicated math operations with tons of digits in her head in just seconds.
- Heel Realization: When cornered in the B. Garden, she admits that she betrayed Sigma because she was terrified during the events of finding the bombs and having succumbed to Radical-6. Waking up after being cured only made her panic ever more because of the second AB gaming nearly ending, and the panic had clouded her judgement as she picks betray. Breaking down in tears, she admits she's a terrible person and feels that it'd be justified if Sigma had killed her out of vengeance there and now. He doesn't.
- Heroic BSoD: In her route, her Radical-6 symptoms were getting stronger and made her succumb to them. While she had acted like a complete jerkass during the first round, the second one had much more meaning to her, since she essentially could tell she was waking up from a nightmare and entering another one. The stress greatly encouraged her to get the hell out without even caring about Sigma's situation, and she apologizes to him when he confronts her.
- Hidden Depths: Even after the revelation that she's a secret agent, it comes as quite a surprise when it's revealed she's a math genius, able to quickly determine the factors of a 25-digit integer.
- Hidden Heart of Gold: As revealed at the end of her route, most of Alice's smugness is an attempt to hide the fear and despair she feels from being forced to play the Nonary game. It also acts as a defense mechanism to help her cope with the pain and trauma caused by the death of her father and her repeated failures to avenge him. After opening up to Sigma, she gets significantly more sympathetic.
- When the gang has to go through the blue, green and red Chromatic Doors in the cyan route, Phi once proposes that the ones who have the least BP (herself and the player, among others) decide which option is done. Alice heavily disagrees, and instead asks for a general ballot, which she considers is "fair". The thing is, when in another timeline it's her who has 1 BP, she proposes that the ones who have the least BP decide which option is done, which is of course the "fair" thing to do. It doesn't help that everyone agrees with whatever she says either time.
- When she spends one round on a team with Sigma and Luna and ends up stuck in the infirmary by the time the voting starts, she will show up during the voting process without anyone realizing and choose "Betray" despite the fact that it would cause Sigma to run out of points and kill him should he and Luna pick "Ally". In the event that Sigma picks "Betray", which is likely because players saw what would happen if he picked "Ally" first, she's has the gall to call him out as a Dirty Coward despite her willingness to betray his and Luna's trust and kill him out of paranoia. In all fairness though, she does later acknowledge that this was dick move on her part and would understand if Sigma wanted to kill her in revenge.
- Jerkass: In her route, she betrays you twice in a row. The first time could be excused as her not trusting you, but the second time counts as a Kick the Dog moment as she picks betray again, knowing that you only have 1 BP left. In fact, in the Alice game-over ending where you pick "Ally" and thus get reduced to -1 BP, this essentially means Alice kills you! Even worse, she is betrayed by everyone else in every other timeline. When Sigma chooses to Ally with her, she betrays, mocks Sigma for picking the very same option that she chooses in all other timelines, and calls him an idiot. The second betrayal also comes after Sigma saves her life with a cure for her disease and is a complete surprise, as she was thought to be asleep in the infirmary at the time and thus would've defaulted to Ally.
- Mind Screwdriver: For the Gainax Ending of the previous game. Turns out she's a normal person with a past and a childhood, not an ancient Egyptian queen with a body made of Ice-9. As she explains, there was an ancient Egyptian mummy recovered that remained frozen at room temperature, but the "All Ice" mummy got corrupted into "Alice" when it became an urban legend, which is how the Alice we know got mistaken for "All Ice". It didn't help, Alice admits, that sometimes just for kicks, she'd tell people that maybe she was the mummy but lost her memory or something.
- Not Distracted by the Sexy: Throughout the entire game, nobody comments on her Stripperiffic outfit. And no one cares about her teases. Dio makes a joke about her bust size, but not her clothes.
- The Reveal: She works for the Department of Defense as an anti-terrorism agent investigating the Myrmidons and Free The Soul, and seeking to avenge her father's death at their hands. She was kidnapped alongside Clover by Zero on the eve of a raid on the Myrmidons HQ, then placed into cryogenic statis so they could be awoken decades later for the Nonary Game. Alice was specifically chosen because of her savant-level grasp of mathematics, which proved vital for decrypting a Myrmidons code. As for the rumour about her body being made of Ice-9, that's not true... probably.
- Sacrificial Lion: She's a mysterious woman with secret knowledge, fighting abilities and one killer outfit. If the world were fair, she'd be a powerful ally for good. The world is not fair, because she almost always succumbs to Radical-6 and commits suicide.
- The Tease: The one who flirts the most with the other guys, although she never uses it to her advantage when decisions need to be made.
- They Killed Kenny Again: Happens so much in several timelines that the player is left wondering if she can even be saved.
- Throw the Dog a Bone:
- In the Golden Ending, she is cured of Radical-6 and ultimately survives the game.
- Her choice of betraying Sigma in the first AB Game round in her path could be seen as this, after suffering the fate of always being betrayed in almost all timelines.
- Vapor Wear: She would be topless if it weren't for that big necklace suppressing the central part of her breasts. No bra. One must wonder what kind of hell she goes through while running. When questioned about it in some routes after implying that she's some sort of covert agent, she explains her wardrobe choice with "in my line of work, the less I look like what I am, the better."
- You Killed My Father: Upon finding out that Dio is the leader of the Myrmidons (the organization that killed her father), she wastes no time subduing him and throwing him to the ground.

The AI controlling the Nonary Game, who manifests as an image of a rabbit. He is not the mastermind of the Nonary Game, but merely a construct programmed by the real Zero to facilitate it. He likes to makes rabbit puns.
- Artificial Intelligence: A product of the 2070s, he is quite intelligent and is indistinguishable from a sentient being.
- Big Bad: He is the one actually running the game in the absence of his creators.
- Big Bad Ensemble: With Dio/Left, who has a separate and equally antagonistic agenda.
- Deadpan Snarker: He's an endless tide of sarcastic jokes.
- Disc-One Final Boss: It is made clear early on that he is not the ultimate mastermind, but even then he eventually gets overshadowed by Dio.
- Expy: Has a lot in common with Monokuma from Danganronpa, another Spike Chunsoft-owned series. Tarako even ended up replacing Nobuyo Oyama as the voice actress of Monokuma.
- Hair-Raising Hare: As the mastermind (as it initially seems) of the game, he is certainly coming off as this.
- Just a Machine: His engrossing personality to the players may make some doubt that he really is an A.I. Seeing him completely subdued & submissive to Akane is pretty jarring.
- Large Ham: Between the screeches, the rabbit puns, and the constantly switching accents, it's obvious the VA for this character had a lot of fun.
- Moon Rabbit: How appropriate that the AI controlling the facility on a moon base would be a rabbit.
- Motivational Lie: He tells Sigma and Phi that they have 9 minutes to escape the elevator at the very beginning of the game, because it's going to fall down from very high. Of course, the AB room isn't going anywhere he just wants them to leave as soon as possible so he can tell them the rules.
- The Nicknamer: All the participants get nicknames from him. Sigma is "Siggy"note , Phi is "Phido", Clover is "Cleaver", Alice is "Alas", Quark is "Quirk", Tenmyouji is "Tenmyoldy", Luna is "Moony", Dio is "B.O.", and K is "Potassium".
- Pungeon Master: The rabbit and vegetable puns fly freely with this one.
- The Reveal: His true name/designation is Lagomorph.
- Troll: After the first AB round, he tearfully proclaims how sad he is that he won't see the players again... and then bursts out laughing at the idea of him being sad, complete with "neener neener"s. Sigma calls him a dick. He responds, "you mad?"
- You Bastard!: There's only one time he has any real dialogue after the first AB Vote: to tell you how much you suck for betraying Luna at the last leg of her path. So far you'd allied with her twice and breaking her trust right when she was the last living suspect for the murders is too much for her.

The mastermind behind the Nonary Game, and the true Zero III, in the context of the entire series, otherwise known as just "Zero". He/she is nicknamed "Zero Sr." by the players to distinguish him/her from the A.I. calling itself Zero III. According to Zero III, the true identity of Zero Sr. is one of the nine players of the Nonary Game.
- An Arm and a Leg: His arms were blown off in the Mars Mission Test Site.
- Evil Old Folks: Downplayed as he had good intentions, but he still set up the present Nonary game.
- Eyepatch of Power: A result of the accident at the Mars Mission Test Site.
- Eye Scream: His eye was blown off in the Mars Mission Test Site.
- Failure Hero: Despite succeeding in sending his mind to his 22 year old self on Christmas 2028, he was not able to prevent the outbreak of Radical-6 in the Mars Mission Test Site; consequently losing his arms & right eye in the process before returning to his true body several weeks after the outbreak occurred. It's all but said that the "unexpected variable" in the Golden Ending will help him & Phi accomplish that which they couldn't do alone in the next Zero Escape game.
- Greater-Scope Villain: Due to setting up the game but not actually being present.
- Impossibly Cool Clothes: Quite an authority-exuding outfit.
- I Did What I Had to Do: Designed the AB Project to save humanity, and was all too aware of all the death and temporal shenanigans it would cause.
- Memory Gambit: An interesting blend with Mental Time Travel. He had his entire consciousness transferred decades back in time so the participants of the game wouldn't discover that he was Sigma, the player, all along. When another consciousness of his arrived from the past at the start of the game, he didn't remember anything of The Plan because, well, he hadn't planned it yet. Sigma's realization that he was the real Zero III without his memories comes as The Reveal.
- Motive Rant: The only time we get to hear Zero Sr. speak is when he delivers an odd speech comparing humans to termites, in that termites build massive structures their individual brains are too tiny to comprehend. This is hinting that only someone with the power to mentally jump through time can properly appreciate the true nature of things.
- Non-Action Big Bad: He's the least active Zero. Zero III runs the game for him and he only speaks to some of the participants through recordings. But considering how he's not mentally present throughout the entire game, it's understandable.
- The Reveal: Zero Sr's true identity is Dr. Sigma Klim, an older version of Sigma who collaborated with Akane Kurashiki to fulfill the future she had seen in her psychic visions and rewrite history to prevent the outbreak of Radical-6. Due to the success of the AB Project, he manages to send his consciousness back in time, swapping it with that of his 22-year-old self.
- "Well Done, Son!" Guy: Genuinely has always loved his "son" Kyle, but was too consumed by his research & general awkwardness to show it much.
Mysterious Old Woman
Voiced by: Yoshiko Sakakibara (old, JP), Miyuki Sawashiro (young, JP), Ali Hillis (young, EN, original release), Rena Strober (young, EN, Nonary Games release) Barbara Goodson (old, EN)
An elderly woman whose body is discovered early in the Nonary Game in the Yellow/Magenta routes. Actually Akane Kurashiki.
- Animal Motifs: Rabbits. An A.I she designed looks like one, one of her earliest memories involves a group of murdered rabbits, and she lives on a lunar base, referencing the 'rabbit in the moon' myth. Fittingly, she's a sly trickster talented at appearing less threatening than she really is.
- Barrier Maiden: Her fate in the Nonary Game is the primary decider of whether or not the players will be able to succeed in fully beating the game. If the players find her dead body, as they do in two of the possible paths, they all immediately suspect one among them murdered her (correctly) and become very suspicious and untrusting of the others, as well as desperate to escape before the murderer kills again. In these paths, the players are much more selfish and dishonest, and most will jump at the first opportunity to screw everyone else over to get out first. If the players don't find her dead body, they're much more keen to trust and work with others, which creates the one scenario where everyone gets to 9 BP and they all escape together.
- Blue-and-Orange Morality: Word of God states that because of Akane's ability to see and live other futures and pasts, she has experienced so much that it is as if she has lived for a million years, and accordingly, her concept of morality has become different from an ordinary person's.
- Cool Old Lady: She is quite cordial and well-spoken to the players, particularly when she is in K's armor in the Cyan door route.
- Eternal Love: Akane once told K that she regrets abandoning ordinary life and the love of an (unnamed) man in order to complete her great work. (Her choice of password implies that this man is Junpei Tenmyouji.) Her love is not reciprocated, because Junpei hates what that work has turned her into.
- Evil Old Folks: Downplayed as she has good intentions, but she still set up the current Nonary Game.
- Greater-Scope Villain: She set up the game, but spends most of the story dead.
- Hijacked by Ganon: She is Akane, the original Zero, and helps the next Zero set up the game.
- I Did What I Had to Do: In order to create history as she'd seen it and to nurture the powers of Sigma and Phi, death was unavoidable. Hers and several others, depending on the timeline.
- It's Personal: Her plan is as much done to spite Free the Soul and Brother, the ones ultimately behind the First Nonary Game where she burned to death, as it is done to save the world.
- Loved I Not Honor More: She genuinely loves Junpei, but between their happiness and the world's safety, the world always comes first.
- Mr. Exposition: Explains several things in the True Ending, though not as much as Sigma (or the player) would like.
- My Death Is Only The Beginning: Akane is quite aware that she will die in several timelines, and that it is necessary to achieve her goals. The AB game is part of her Thanatos Gambit.
- Never Mess with Granny: She's manipulating the entire cast to serve her Long Game, whether they know it or not, and is the most knowledgeable esper among them.
- Posthumous Character: As always, depending on the timeline.
- Previous Player-Character Cameo: She was one of the two main characters of 999.
- The Reveal: Her true identity is Akane Kurashiki from Nine Hours, Nine Persons, Nine Doors, one of the conspirators behind the AB Project and the current Nonary Game. Using her powerful psychic foresight, she orchestrated a decades-long plan to rewrite history in order to prevent the release of the Radical-6 virus and get her revenge on the last remaining mastermind behind the first Nonary Game: Brother, the leader of Free The Soul.
- Seer: Her actual power as an Esper. Although she can't change the past, she can explore the future, and plan accordingly.
- Theme Song Reveal: Morphogenetic Sorrow begins playing while Tenmyouji talks about her- even before her name is revealed. It also plays during a scene in Luna's ending, hinting at her identity.
- Time Abyss: From a mental standpoint, in any case. She is about as old as Tenmyouji, physically. According to Word of God, her psychic powers have developed enough that she can send her consciousness across time and space, almost at will. She has seen and felt enough in this way that she could be said to be millions of years old, mentally.
- Vocal Dissonance: With the English voice acting from the original release, young Akane sounds more cold, calculating, and mature than her young and innocent looks would lead you to believe. Averted in The Nonary Games, which uses the same actor from the remastered 999.
- Walking Spoiler: Anything you hear about Akane in VLR will mention her corpse.
- Workaholic: Devoted 50 years and, presumably, a small fortune (given that she ordered Sigma to create a fully sentient robot and somehow took up residence in an abandoned lunar base) to stop the apocalyptic release of Radical-6 and, incidentally, get revenge on Brother.

A GAULEM Sigma encounters in Luna's route. He has inexplicably been given the personality and accent of a Cockney man.
- Author Filibuster: Basically exists to give you a long speech on the nature of Artificial Intelligence and Do Androids Dream?.
- He Knows Too Much: Not that he knew too much, but that he was about to say too much. He was disabled and presumably later deleted when he nearly revealed the presence of a GAULEM participating in the Nonary Game when he tried to get ABT for himself.
- Killed Mid-Sentence: Because He Knows Too Much.
Note: Radically different information about Brother is revealed during Zero Time Dilemma. This entry explicitly disregards that information in ZTD to avoid spoilers; see his character section there for more information.
The Greater-Scope Villain of Virtue's Last Reward, Brother is the name given to the mysterious leader of the cult "Free The Soul". He is an esper, born with psychic abilities that were said to expose him to "the worst aspects of humanity". After the murder of his beloved brother Left (and subsequent police cover-up on behalf of the killer), he was driven to madness and came to believe that God had given him a divine mission to cleanse the world and bring forth a new species of humanity. To this end, he founded the cult "Free The Soul Of Y" (later truncated to "Free The Soul") and the terrorist organisation "Myrmidons". Somehow he was able to orchestrate the release of the Radical-6 virus into the general population, which led to a disaster that nearly drove the human race to extinction. Through his psychic abilities he learned of Akane and her attempt to stop him by rewriting history, so he sent Dio to Rhizome-9 to stop it.
- Greater-Scope Villain: To the entire series, as the leader of the cult that is ultimately responsible for both the First Nonary Game and the Radical-6 outbreak.
- Mission from God: After Left's murderer got away with his crime scot-free, Brother went into a deep sabbatical for nine days and nights. On the tenth day, he believed he had contacted God to give him his mission to create a new form of humanity & wipe out those who were "unclean".
- Staying Alive: Word of God states that he is still alive even in the Bad Future of this game despite being an old man in the "present". How has yet to be revealed conclusively, but one rumor is that he has cast his body into another time.
- The Unseen: Other than a depiction that shows him with an unspecified face, we never see Brother in this game.
- Walking Spoiler: His presence reveals quite a bit of the games true purpose.
