Player characters and major NPCs first introduced in Round One of Airlocked, its deadland segments, and its intermission, covering their appearances before the final round. For characters who survived to that point, see Airlocked Round Five for spoilers for that round.
Champion of Counterfeits
- "If you have nothing of value to add, stop wasting my time and clean up the mess you've made."
The victim of Week 2 (Case 2).
- Alliterative Name: Though she doesn't use her surname due to her family making her into a tool, it's listed in full on the profiles.
- Artificial Human: Her species is listed as "doll."
- Competition Freak: She takes the dodgeball game very seriously.
- The Cynic: She despises optimism and idealism and automatically thinks everything will end in murder.
- Girlish Pigtails: One of many twintailed characters this round.
- Greeting Gesture Confusion: Doesn't know what a fistbump is.
- Identical Stranger: Angelica is nicer to Ricky than to most people, and she looks like an older version of Ricky, even though they're the same age.
- Ninja Maid: Describes herself as "the Ainsworth family's first line of defence."
- Our Souls Are Different: Her soul was damaged in the process of transferring it to a "doll." Seth offers to fix it because, as a scientist who works with the soul, he's offended by what he considers to be a hack job.
- She's Got Legs: This is mentioned about her a few times, particularly when she's wearing the frilly dress.
- "...why do things like 'bonds' and 'trying to keep people from fighting' keep tripping me up after so long...?"
Made it to the survivor pool.
- Aristocrats Are Evil: More of a jerk than outright evil, but still.
- Bastard Bastard: A lot of his selfishness and condescension most likely comes from competition with his massive number of half-siblings, which he tells everyone about later on.
- Blue Blood: He comes from a rich and powerful family and takes a lot of pride in it.
- Compassionate Critic: Starts to turn into this when he becomes nicer, since he's still a jerk.
- Complexity Addiction: Togami likes to needlessly complicate things, thinking it keeps himself safe. A major example is the Secret Test hidden in his long, written-out family history with a Schmuck Bait label.
- Determinator: You can say a lot about Togami, but you can't deny that he digs his heels in and fights for what he wants."I didn't survive all these years by running away from danger, if that's what you're asking."
- Experienced Protagonist: The only one who's been in a Deadly Game before.
- Ineffectual Loner: His experience leads him to close himself off and drive people away, only to remember that unity and trust are what's needed to survive. Even Temerity calls him on it!
- Last-Name Basis: Called "Togami" by everyone, even the narration.
- Mystery Magnet: Those who uncover Togami's past end up deciding he's one of these and a murdergame magnet in particular.
- Non-Uniform Uniform: Started the trend of wearing bedsheet togas over the jumpsuit.
- Properly Paranoid: Togami can't trust anyone and sows discord among the group by positing that one of them is a traitor. Harsh, but he has been through this once before.
- The Proud Elite: Stuck-up and proud of his fortune, even if he knows from the beginning now that none of it matters anymore. It fuels a rivalry with Jane, a much nicer and more down-to-earth heiress.
- Rules Lawyer: Has memorized the rules and can cite them on command to provoke people into punishment or have them left alone. Of course, sometimes he omits pieces to assure people that they'll be fine when they won't.
Champion of Curiosity
- "I'm good at finding all of the pieces of the puzzle. I know how all of the parts work and what they all are. But I'm not very good at actually putting them all together."
The victim of Week 1 (Case 1).
- 100% Adoration Rating: Everyone but the heartless Seth finds Chitanda lovable and worthy of protection. Toby killed her by mistake, wanting to target someone else.
- Constantly Curious: Her title references this and she's awed by others' stories of their worlds.
- The Cutie: A young, moe girl everyone immediately wants to protect.
- I Just Want to Be Badass: Chitanda gets Lightning to train her so she won't be an easy target.
- Last-Name Basis: Nearly everyone calls her Chitanda, and her name is the only one listed in Eastern order on the profiles, even though there are others whose names could be listed that way.
- Moe Stare: Chitanda's default expression.
- Morality Pet: To Lightning, before Lightning starts to defrost around the others and Chitanda's no longer there.
- Shipper on Deck: Chitanda wants Lightning and Xander to get together.
- Smitten Teenage Girl: Just ask her about her crush back home.
- Wide-Eyed Idealist: She really thought they could all get out without worry.
Champion of Suspended Animation
- "Most of the time, I'm not even thinking about the danger. I just think, 'what do we need to do to get through this?'"
One of the victims of Week 5 (Case 5).
- Bucket Helmet: Ricky wears a pot on her head before replacing it with a football helmet.
- The Confidant: The first person Kurumi tells her secret to.
- Crippling Overspecialization: Nearly all her abilities rely on guns, which she doesn't have access to here. Ironically she's a Jack-of-All-Trades when she's armed.
- Girlish Pigtails: Hers are lower down than Kurumi's or Angelica's.
- Human Popsicle: It's right there in her title. Technically, she's over 1,000 years old.
- Identical Stranger: Looks like a younger Angelica.
- I Don't Know Mortal Kombat: Ricky is often found playing the zombie-shooting game and seeing if she can be good at it just because she can shoot in real life. Her failing at it foreshadows her death at the hands of Zombie Infectee Kurumi.
- Improvised Armour: Aside from the aforementioned Bucket Helmet, she carries a pot lid "shield."
- Older Than They Look: Not to the extent suggested by her profile (which counts her time spent in suspended animation), but she's still a purported adult who looks like a kid.
- Princess for a Day: When the dead visit Disney World during round 3, she immediately moves into Cinderella Castle and starts dressing the part.
- Tomboyish Name: Her nickname, Ricky.
- Wrong Genre Savvy: Downplayed somewhat, as she does understand what kind of situation they're all in, but she could probably stand to be reminded that she isn't in a Dungeon Crawler anymore, so there's no reason to hoard consumable regains or redundantly map out the station, "protective" items are only useful if they provide actual protection, and there's nowhere to sell those feathers she's collecting.
- "If the Maid of Life can't bring anyone back, she can at least keep anyone else from leaving with all of her might."
Made it to the survivor pool.
- Amnesiac God: Much like Lightning, she's forgotten achieving God Tier or even what that means.
- Antiquated Linguistics: Her speech is about a century out of place from where she's actually from. It's how she understands Thomasin more easily.
- Badass Mustache: Jane likes to wear fake mustaches to be silly. Fun fake-mustache prints were a fashion trend in late 2011, which is when she first left Earth, and she's always liked the idea of the distinguished gentleman. As the game goes on, she takes an active role and becomes closer to being The Hero than she ever got to be in canon.
- Broken Pedestal: As she regains her memories, Jane realizes that the ancestor whose legacy she did her best to live up to really was as evil as her "weird" friends used to say.
- Costume Evolution: Sews a red lumpy skirt at the first opportunity and wears it over her jumpsuit, then regains her ghost beast shirt from canon and wears it with the skirt, and finally replaces the skirt with a black one.
- Covert Pervert: Very aware of how much the supplied jumpsuits shows off the bodies of her fellow Champions, falling in line with some of her observations in canon.
- Every Scar Has a Story: Jane can't remember where she got any of hers, but over time, starts to recall each one from her injuries in Sburb.
- Fantastic Racism: Biased against AIs, automatically blaming them for problems. After C.E.C.E.'s HeelFace Turn, Jane views her as an exception.
- Funny Spoon: Her Weapon of Choice, actually.
- Girls With Mustaches: She likes to wear fake ones.
- Gosh Dang It to Heck!: With a side of Curse of the Ancients, since she's a time-switched, reality-reset Alternate Self of an old lady who talked like this.
- Hard Boiled Detective: Aspires to be one, and is the main similarity between her and Chitanda Eru that bonds them in friendship and inspires them to start a joint detective agency with Xander as their secretary. After Chitanda's murder, she carries on the agency in memoriam.
- Hollywood Pudgy: Jane is a bit above average weight for her height and age but, in canon, is depicted with a range of body types and most often as a generic sprite.
- Knife Nut: While she does switch her Weapon of Choice to knives, she's still a lot more grounded than most of these.
- Meganekko: A cute, intelligent glasses-wearing girl.
- Outdated Name: Which makes sense, because she was basically born from a time paradox and it matches how she talks.
- Precocious Crush: She's a little prone to these, being initially attracted to Xander before he started seeming too much like a dad, then her black crush on Togami flipping to red (he's 21 and she's 16).
- Prince of Pranksters: Jane is usually a harmless prankster, but some of her antics can get annoying to others (like the Salt and Pepper Diner) and, when she's trapped with her Sitcom Arch-Nemesis, she drives him up the wall with pratfalls and obnoxious music set to elaborate traps. She takes a lot of pride in her accomplishments.
- Sarcasm Mode: Jane slides into this a lot if she gets into an argument."Oh, no, Mister Togami, I insist, lead us by way of your impeccable example to sift through pretzels and Tang, it would be an honour.
- Skilled, but Naïve: She's always wanted to be a detective and built her skills solving fictional murders, which makes her a big help in the trials. Still, Jane acknowledges that she was nowhere near prepared to deal with real murders, and the trials take a huge, visible emotional toll on her.
- Skirt over Slacks: Between the sewing room opening up and regaining her shirt, she usually wears a janky handmade skirt over her bodysuit.
- Supernaturally Young Parent: Jane discovers through her memories that, thanks to Time Travel and genetic engineering, she has two children her own age.
- Supreme Chef: As heir to a baking empire, while she can make realistic mistakes, she's very accomplished.
- Taught by Television: Her aptitude at solving mysteries. However, while her interest in mystery fiction does make her good at it in real life, the real consequences scar her badly and put her off her former interest in fictional mysteries.
- Team Chef: She would like to be this, but the ubiquity of premade food keeps thwarting her.
- The Team Normal: Subverted. She thinks she's this, but starts to learn that her life is more messed-up than anyone's.
- True Blue Femininity: Associated with cyan, to offset the Mega-Corp she's set to inherit, which is associated with bright red.
- Weapon of Choice: Initially spoons and forks. After she regains enough memories, anything associated with Betty Crocker is tainted to her, and she switches to Lightning's knife instead.
Champion of Inoculation
- "I have every right to be angry."
One of the victims (and culprits) of Week 5 (Case 5).
- Badass Adorable: She likes to train and is always wary of danger, but she's still darn cute.
- Dead Man Walking: Part of her secret, and the part she kills for, is that her medication is only a temporary solution and she's bound to become a zombie.
- Easily Forgiven: For killing Ricky, especially by the victim herself, who even gets over dying via Deadly Hug to cling onto Kurumi when they meet again in deadland.
- Evil Is Deathly Cold: Subverted. She's constantly unnaturally cold, but is actually a good person.
- Girlish Pigtails: A hint that Kurumi is still just a normal teenager in a bad situation.
- Girly Bruiser: A cute girl who's The Big Guy in her own group back home and still feels vulnerable when she can't bash enemies with a shovel.
- Irrational Hatred: Kurumi has a few anger issues and misblames Ricky for a death that was at best tangentially related to something made for her for non-murder-related purposes. While she gets past this and even falls in love with Ricky (but murders her in cold blood after confessing her feelings anyway, to save her friend's sanity), Kurumi does it again in week 5, burning Bolton's books just to hurt him after a motive comes down... that Bolton wasn't the one to hand out.
- Weapon of Choice: Hers, a shovel, is mentioned on her profile.
- Zombie Infectee: Kurumi's secret, which she confesses to a spare few close people, is that she's been bitten. She takes medicine to fight it off, provided regularly by the Benefactors.
- "This body is my own. No secrets, no tricks. I am who I've always been, even if I'm not truly human anymore."
One of the culprits of Week 5 (Case 5).
- Affectionate Nickname: Her closest CR gets to call her "Light."
- The Aloner: Halfway into the game, she remembers becoming a Physical God and having to cut herself off from people. Lightning doesn't want to go back to that, but sees no other choice. She warms up to connections again later, though, even if it turns out to be the reason she becomes a culprit.
- Amnesiac God: Since her assumed canon point is the very start of the first game, she thinks at first that she's a normal person.
- Big Sister Instinct: Towards the younger characters, Chitanda in particular.
- Big Sister Mentor: Lightning acts like this to a number of other characters, whom she starts to teach how to defend themselves.
- Boots of Toughness: She can even use them to crush a lemon under her heel.
- Cats Are Snarkers: Probably one reason she regains a catgirl costume.
- Defrosting Ice Queen: After the first week, she remembers making friends and becomes less closed off.
- Divine Date: To Xander, once she remembers becoming a Physical God.
- Do Not Call Me "Paul": Doesn't go by her original name and won't even let anyone call her "Light" until they're extremely close to her.
- Heartbroken Badass: Her initial canonpoint is at the beginning of the first game, and she's full of regrets for her sister.
- I Can't Dance: She refuses to out of embarrassment.
- Knight in Sour Armour: Lightning acknowledges that it's a good thing to try and protect everyone and she'll put in the effort, she just doesn't think it's possible and will say so. This positions her as a foil to both Yurika, who, despite having seen and had to do awful things, still has an optimistic outlook, and Seth, who's Seen It All and decided that there's no point in being anything but cruel and cynical (at least that's what he says his rationale is).
- Mark of the Supernatural: Hers is gone, and she can't remember why at first.
- My Greatest Second Chance: Lightning decides that, even if she can't protect everyone, she'll keep Chitanda safe like she failed to do for Serah. Sadly, it doesn't work.
- Names to Run Away from Really Fast: She changed her name to "Lightning" to invoke this when she wanted to become strong.
- Number Two: Jamie seems to have her pegged as Xander's second-in-command.
- Shameless Fanservice Girl: Finds the skimpy catgirl outfit just as acceptable as her more normal clothes and doesn't even get embarrassed.
- Sour Outside, Sad Inside: She's cynical and hates a lot of things, but chief among those is herself.
- Violently Protective Girlfriend: In Round 2, she threatens Takumi for speaking ill of Xander.
- You Remind Me of X: Chitanda reminds her of her sister, Serah.
Champion Flaming Swordsman
- "Obviously, this course of action has a high risk, but going into it with an assumption of dying helplessly won't do any of us any favors."
The victim of Week 3 (Case 3).
- Anime Catholicism: Well, Futuristic Catholicism with shades of this.
- Blood Knight: Margulis only seems to have fun when he's fighting.
- Combat Pragmatist: Says that no one will come for him because the cause in the war back home is more important than rescuing one person. He also tries to sacrifice everyone for The Needs of the Many.
- Double Speak: Margulis is prone to this, given the subterfuge of his job. How he knowingly speaks with hidden meanings all the time, especially with the subtlety of his dying letters and the slight difference between McBurn's and the others', and yet misses all the Innocent Innuendo he says is a mystery for the ages.
- Good Scars, Evil Scars: Has a scar across his eye. When they first meet in deadland, Max tells Margulis that the scar on his face makes him look like a kids' show's villain.
- Last-Name Basis: Margulis has this with everyone. He also goes by his last name and not even the PIP gives his full name.
- Must Have Caffeine: If he could wire tea into his bloodstream, he would.
- Not Afraid to Die: To the point that he actually plans his own death, and he goes into trials confidently every time.
- Turns into a full blown Death Seeker after his second memory regain, as his confession letter says that even if he'd escaped the station, he only would've gone on to face the other person worthy of killing him.
- Only One Name: His first name is never given.
- Spirited Competitor: Loves the thrill of fighting and wants a strong opponent to "satisfy" him, which easily fuels the Ship Tease between Margulis and McBurn.
- Villain with Good Publicity: Due to sharing a space station with people like Seth and McBurn, plus the immediate threat of the Overseers and Benefactors. Coming off as a good guy is simple in comparison.
- You Remind Me of X: McBurn reminds Margulis of an associate he always had to keep in line back home.
- "Oh, there's very little that won't burn eventually."
The culprit of Week 3 (Case 3).
- Blood Knight: Not only does his laziness suddenly vanish when he's fighting, but he also really enjoys himself... in more ways than one.
- Brilliant, but Lazy: Tends to be lazy to the point of even falling asleep out of boredom. Turns out he's incredibly skilled at combat. Sometimes it even seems like the laziness is an act, though why he'd do this is certainly a mystery.
- Combat Sadomasochist: McBurn likes pain and laughs off punishments, weirding out everyone else in the room.
- Dismotivation: He'll only actually do anything if he thinks it's going to be fun.
- Evil Is Hammy: Plays up his reactions to everything. Boredom leads to falling asleep standing and team sports make him a Laughing Mad Blood Knight.
- Four Eyes, Zero Soul: Between him and Seth, it might be a trend.
- Lack of Empathy: He doesn't care about anyone else. Subverted, it turned out he actually has Emotional Powers that turn him into a sadistic killer.
- Marked Change: In his demon form markings that look like flames appear all over his body. He also gains Black Eyes of Crazy.
- Multicoloured Hair: McBurn says it's natural. Everyone else would really like for him not to prove it. On top of this, his hair will do a Power Up Full Color Change.
- Only One Name: It's probably not his real one, either.
- Playing with Fire: He's often seen playing around with a fireball.
- Psycho Party Member: McBurn crafts his own image as one of these to keep the others at arm's length.
- Pyromaniac: Others start to suspect this of him, given how much he loves his fire powers.
- The Slacker: Plays this up to annoy people and keep from having to do any work.
- Smug Super: He brags about his rare, usually much more powerful flame abilities.
- Steven Ulysses Perhero: He has (nerfed) flame powers and he's called McBurn.
- Too Kinky to Torture: The others assume this about him after he actually likes being punished for falling asleep. This is made even worse with his tendency for fire-related innuendo.
- Troll: He admits to Bolton that he just wants to see how much he can get away with.
- Willfully Weak: He has to hold back a lot should anyone actually want to spar with him.
- You Remind Me of X: Margulis reminds him of one of his fellow enforcers and Xander reminds him of another Ouroboros member he's currently working with.
Champion of Pride
- "No. I'm tired of nonsense, this can't continue anymore."
Made it to the survivor pool.
- Blind Without 'Em: Natsuhi has poor vision and only regains her glasses late. She rarely wore them at home, anyway, either, to keep up her image.
- Born Unlucky: The Trauma Conga Line she went through back home is one of many, and she always ends up with the short end of the stick in the space station too, even with little things like getting covered in glitter multiple times or being stuck on her least favourite floor during the lockdown.
- Classy Cravat: Has one on a dress she regains.
- Family Honor: The reason Natsuhi is fixated on keeping up appearances.
- Graceful Ladies Like Purple: Her major clothing regain is a purple dress, and she devotes a lot of time and energy to looking like a perfect lady.
- Hair-Trigger Temper: Snaps and screams when she hears that she's "trying" to be a Proper Lady and interprets it as "not succeeding."
- Happily Married: As frustrated as she can be with her husband and as much as she resented being essentially forced into an Arranged Marriage, Natsuhi still talks about him and their daughter fondly.
- Housewife: Her listed occupation, though she's also rich and has servants.
- I Just Want to Be Normal: Natsuhi never asked to be Trapped in Another World, learn that magic existed, and be surrounded by all these weirdos. She often complains that it makes her head hurt.
- Impoverished Patrician: Her husband frittered away a lot of their money on things like space tourism, and while she was in the running for a large inheritance, she doesn't get that either.
- Locked Out of the Loop: Unintentionally in regards to Temerity's existence. She couldn't be bothered to look at Temerity's messages, since she refused to take part in things like surveys, and everyone else assumed that she knew about them.
- Loner-Turned-Friend: While Natsuhi is still distrusting and insular, she's the one to stand up and unite everyone to save Xander, even if she doesn't know or care much for Temerity.
- Motherly Side Plait: Her hair evokes this, but in a tight ponytail instead to symbolize her strictness. Fittingly, she expresses worry over her family, but is too proud to admit it until she's cornered and she remembers what kind of series she came from.
- Multicoloured Hair: Has a gradient of different shades of brown to red-brown.
- The Proud Elite: It's in her title.
- Robot Buddy: Natsuhi isn't one herself, of course, but she has one: Stabby, the robot vacuum cleaner.
- Seven Deadly Sins: Associated with Pride in canon and in-game with her title.
- Skeptic No Longer: Reluctantly, and even when she does stop questioning all the weirdness, she's not happy about it.
- The Team Normal: Natsuhi is way out of her element and is constantly weirded out at all this futuristic and supernatural stuff.
- They're Called "Personal Issues" for a Reason: Natsuhi develops a reputation for being a private person, keeping her past to herself and viewing attempts to get to know her as suspicious and intrusive.
- Yamato Nadeshiko: What she strives to be.
Champion of Winter
- "If we leave them with our companions, our hearts will live on inside of them."
The culprit of Week 4 (Case 4).
- Bunnies for Cuteness: She (poorly) draws diagrams that represent everyone with bunnies.
- Competition Freak: Rukia takes the dodgeball game very seriously, more than most.
- I Am Not Left-Handed: In her deadly clash with Shadow, she reveals that, while she works hard and is known for her ice magic, she's actually got The Gift for fire spells.
- An Ice Person: The rationale for her title.
- Immortal Immaturity: Acts the age she looks, despite being far older.
- Psychopomp: The meaning of Rukia's occupation.
- Rank Up: Her profile lists her at a higher rank than she remembers, indicating that this happened in her lost memories.
- Teens Are Short: Significantly smaller than the adults on the station.
- Terrible Artist: Though she thinks she's great.
Champion of Detachment
- "I'm full of surprises."
Punished during Week 3.
- Alliterative Name: Her real one, though "Sadie" is likely short for "Mercedes" anyway.
- The Beautiful Elite: Chanel #3 is rich, successful, and conventionally beautiful.
- Emotionless Girl: Though she covers it up with being shallow.
- Hard-Drinking Party Girl: Sadie likes wild parties and sees deadland as one big Beach Episode.
- Lazy Bum: Because she just doesn't care about anything.
- Only Known by Their Nickname: "Sadie Swenson" is only on the profiles. She goes by "Chanel #3."
- Preppy Name: Both her real and used names.
- Public Exposure: Her only reaction to Seth's paintings is that she's never been painted clothed before.
- Rich Bitch: She's never heard of tact, kindness, or being a decent person.
- Sunglasses at Night: #3 seeks out sunglasses to wear even if there isn't any sun.
- You Are Number 6: Her nickname, "Chanel #3."
- "Feelings are complicated. It's why I'm glad I don't have them."
The culprit of Week 2 (Case 2).
- Animate Inanimate Object: While his mask form is not this, he possesses a mannequin in the Round 2 intermission.
- Artifact Alias: "Seth Twiright" is only the name of the body he came in with, but everyone keeps calling him that after he loses that body, when they're not calling him things like Satan Mask.
- Body Backup Drive: It's part of his business to make these, and he has for himself. In the first intermission, he calls the Ainsworth family amateurs for doing this poorly.
- Brutal Honesty: He'll tell everyone to their faces that he doesn't mind being trapped, doesn't care about their worries, and thinks they all can and will kill with the right motive.
- The Coroner: Takes this role during investigations.
- Devil in Disguise: He's the Demon of Wrath and thus has the Fan Nickname "Literally Satan." This is referenced with a number of the characters calling him that in and after his trial.
- Dissonant Serenity: When he loses people he was actually interested in, his regular uncaring scientist persona is overlaid with cold malice and, still as calm as ever, he seeks to purposely upset and offend people, not just do it as a side effect to his Skewed Priorities and Brutal Honesty.
- Evil Laugh: Seth's laugh is always creeping the others out.
- Evil Mask: He doesn't have one, he is one.
- For Science!: He actually seems happy to be kidnapped, because it's something to study.
- Four Eyes, Zero Soul: Possibly literally, on that second part.
- The Friend Nobody Likes: Most of the Champions begrudgingly work with him and trash-talk him while hoping he might be better than he seems. Come his death, Seth fully falls into this role. People mess with his mask form, insult him to his face, and use him as centipede bait, but still at least keep him around to begin with. He's just amused by the whole thing.
- Hate Sink: Becomes this in Week 2 and it only gets worse. He doesn't even care how much the others can't stand him.
- Health Care Motivation: As he tells the Doctor, Seth's world has a horrible disease that affects the Anatomy of the Soul and his children carry it. It's not exactly his motive to save them, though, even if he implies it is. Actually, he himself is the disease.
- Mad Scientist: The Doctor calls Seth one of these because he actually likes the space station and puts his fascination over others' worry.
- Omnidisciplinary Scientist: While he specializes in variable memory and alternate worlds, he claims to work a little in everything.
- Psychotic Smirk: He's sometimes depicted with one of these, especially during his MTB in the second trial.
- Red Baron: Seth's title of "Serpent" is one of these.
- Seven Deadly Sins: Associated with Wrath in-canon, and he's terrifying when he's angry.
- Snakes Are Sinister: "Serpent" is his title and he's not exactly the nicest person in the world.
- Virtue Is Weakness: Seth says this is his view of reality, since his own home is a Crapsack World.
Champion of Promises
- "Not everyone's cut out to suddenly live in a space station with eccentric strangers."
The victim of Week 4 (Case 4).
- The Ageless: He's probably going to be a teenager for a very long time, if he lives.
- Arbitrary Skepticism: Despite being the Trope Namer for Ultimate Life Form and having seen a lot of weird things, Shadow is still skeptical about Margulis's suspicion that the paintings are cursed.
- Conjoined Eyes: Look at him.
- Double Think: Both the likes and dislikes on his profile list his rival from home.
- Emo Teen: Basically one, especially given his age with the suspended animation removed.
- In a Single Bound: Shadow can easily jump above his own height.
- Multicoloured Hair: Fur, actually.
- Perpetual Frowner: Shadow tries to look serious and never actually smiles.
- Pint-Sized Powerhouse: He's smaller than the humans, but easily able to take them on.
- Power Limiters: His have been removed, yet he's weaker than before, thanks to everyone's nerfing.
- Red and Black and Evil All Over: Averts it due to his canon point, but was initially this before things happened.
- Spell My Name with a "The": Averted by the profiles, which remove it.
Champion of Earth
- "Everybody lives. Doesn't happen often, but we'll make it happen."
Made it to the survivor pool.
- Arbitrary Skepticism: Call something science and he'll believe it. Call it magic and he'll think you're making it up.
- Close to Home: The first culprit's motive and confession, to him.
- Cool People Rebel Against Authority: He says he's always been contrary and disregards directions.
- Deadpan Snarker: Makes wry comments all the time, especially during confrontations like trials.
- Double Think: The Doctor both loves and hates people.
- Experienced Protagonist: The only one with experience with alternate worlds.
- Human Outside, Alien Inside: He looks just like a human from the outside but his organs are apparently completely unlike a human's.
- Insufferable Genius: Shadow calls him one, saying he's a stubborn know-it-all but actually always right.
- It's All My Fault: He blames himself for a deep regret that cost a lot of lives.
- Shell-Shocked Veteran: Thus, the Doctor takes the situation very seriously.
- Speaks Fluent Animal: He does normally, which tips him off that there's something up with the space pigeons, since they're not speaking intelligibly in bird.
- Stepford Snarker: Seems a lot less bothered than he actually turns out to be. Especially around Seth, whom he despises and will often take jabs at.
- Sympathetic Murder Backstory: The victim being an entire planet instead of a single person, but the Doctor regrets it and believes he didn't have a choice.
Champion of Fasting
- "While many humans are fools, there are some exceptional ones."
Killed for interfering with the Case 1 execution.
- Big Brother Instinct: Comes to see Toby as a brother after he comments that all Aviants are brothers, and constantly defends him in the first trial. He ends up dying while trying to save Toby from his execution as well.
- Cultural Posturing: Not very obvious, but he doesn't think much of humans in general.
- Have I Mentioned I Am a Dwarf Today?: Talks a lot about being a griffin and how he isn't used to or fond of humanity.
- Last of His Kind: He hasn't met another Griffin for several centuries now.
- Only Sane Man: Weird as he may be, he's the voice of reason in deadland for most of the round.
- Our Gryphons Are Different: This one flies, has fire powers (his tail heats up), can go a long time without food, and only eats good humans. Though he reveals after Round 1 that he can actually eat normal food, too.
- Picky People Eater: The Griffin actually eats humans, but will only eat good people.
- Species Surname: Species name in general.
- Super-Speed Reading: He goes through stacks of books on completely unfamiliar material like it's nothing. It helps that there's nothing else to do.
- "There is no chance left to me of salvation — that is what I thought. Now I know not what the truth is, but if my soul is deeded away, what matters it what I think?"
Made it to the survivor pool.
- Antiquated Linguistics: Given when she's from, this is expected.
- Blood-Splattered Innocents: Thomasin arrives at the station covered in blood with no memory of why. The image is evoked again when McBurn takes a knife to himself and his blood covers Thomasin's oxygen pod at the third execution.
- Claimed by the Supernatural: Starts to become more and more sure that she's marked by the devil goat that haunts her dreams.
- Clarke's Third Law: When Togami's virtual reality theory and other futuristic concepts make no sense to her, Thomasin needs to have them explained like they're magic.
- Fish out of Temporal Water: Oh, so much. Forget the space age, she needs help understanding indoor plumbing.
- The Fundamentalist: Fills this role due to coming from a centuries-past, extremely religious society, as in "can't even work on Sundays or celebrate holidays."
- The Heretic: Her title, since her family was run out of town for differing beliefs. She's still extremely religious.
- I Just Want to Be Loved: With her family gone and half of them having hated her to begin with, Thomasin is, in the end, a scared and lonely person. She's convinced to cooperate and try to save Xander instead of condemn him and try to become the Ultimate Champion herself when Jane appeals to Thomasin's desire to have people around her instead of being left alone again.
- Never Learned to Read: It's why she has to have the rules explained to her. A few people start teaching her how.
- Self-Made Orphan: Learns with horror that she killed her mother in self-defence after her father was killed by their goat.
- Sympathetic Murder Backstory: Thomasin certainly doesn't think it's sympathetic and made a Deal with the Devil after killing her mother because she believed she was already going to hell, but the others acknowledge that it was self-defence and her repressive culture was what made it worse.
- Textile Work Is Feminine: Thomasin tries to sew clothing and various things out of bedsheets to keep herself busy and make more modest clothing than the skintight bodysuits.
- Troubling Unchildlike Behaviour: Drinks beer because she's from a time when kids were given it all the time thanks to contaminated water.
- What Have I Become?: The trauma of her memories makes Thomasin slowly realize in horror that she became a Self-Made Orphan and the very kind of Wicked Witch she'd always feared.
Champion Weapons Engineer
- "I'M NOT ADORABLE. I'm the HARBINGER OF DEATH. I'm MURDER INCARNATE."
The culprit of Week 1 (Case 1).
- Badass Adorable: Small, cute, and a hardworking weapon master.
- Badass Boast: Toby is prone to these, especially when someone's just called him cute instead of threatening.
- Bird People: Not really a penguin, but an alien who looks like one.
- Everything's Better with Penguins: He's a penguin alien.
- Intrigued by Humanity: Toby makes an effort to try and learn about how humans work and read about their culture. It doesn't work perfectly, since all the books he comes across are about space.
- Mix-and-Match Weapon: Gets excited about making these, like his idea of giving Xander a sword that doubles as a gun.
- The Napoleon: He takes himself seriously enough that he gets really angry when people call him small and cute and don't treat him as a threat.
- Pint-Sized Powerhouse: Tiny, belligerent, and very good at fighting and building weapons.
- Shorter Means Smarter: A weapon-building tech enthusiast who has to stand on a stack of books to reach anything.
- "If all you learn is fighting, it's hard to remember what you're fighting for."
The culprit of Week 6 (Case 6). Made it to the survivor pool.
- Amazon Chaser: Xander is attracted to Lightning because she's a strong and capable fighter.
- The Atoner: Becomes this after 1-6 and through the endgame and intermission.
- Badass Bookworm: Xander is both well-read and works hard to improve himself in combat.
- The Beautiful Elite: Much mention is made that Mr. Fanservice is a prince.
- Bookworm: Often found reading the space nonfiction so he can get caught up with higher Technology Levels.
- Broken Ace: Putting leadership and duty first, especially given his messed-up home and going from that to leading a group of strangers, takes a lot out of him. He reflects that he's never been able to be a person, as much as he comes off as an ideal.
- The Chains of Commanding: He reflects that he's never been able to "just be Xander," and even early on, Margulis notices and tells multiple people to watch out for Xander and let him relax a little. The stress is worse because he's not just the leader, but a Mole in Charge.
- Classy Cravat: Wears them with most of his outfits, since he's the crown prince of his homeland.
- Crazy-Prepared: Keeps anything if he thinks it might be useful later on.
- Dark Is Not Evil: While Xander comes from a conquering empire that uses dark magic and is pulled from the route where he's an enemy, he's still more of a Noble Top Enforcer who tries to mitigate the damage, and in the space station, he's a responsible, caring leader.
- Death Seeker: Reflects that dying might be easier than trying to live with everything he's done both in canon and in the game. He tells Jamie that he can kill him for revenge after all this is over, and his relief when Jamie approaches him in the pool and then says he didn't come to kill him is tinged with disappointment.
- Despair Event Horizon: Lightning's death, immediately followed by remembering Elise's, send him into a Heroic BSoD that would make Sad Roomba Dave proud.
- Distressed Dude: Xander's arms are bound in the week four sabotages, while he's stuck wearing a Speedo. Lightning tries to look less happy and/or embarrassed than she is.
- Even the Guys Want Him: Both Overseers immediately say that, if they had to pick a Champion, it'd be him.
- Face of a Thug: He's described as having a permanent intimidating scowl.
- Flower Motifs: Associated with the black-red rose that is his family's standard.
- From Zero to Hero: Xander says he was untalented to begin with and got where he is with hard work.
- Has a Type: It's often commented that Xander has a thing for people who are strong enough to protect themselves, since he grew up in a very dangerous environment and doesn't want to lose anyone else.
- Heroes Prefer Swords: Once he's given up being The Mole and is more of a hero figure, Xander is soon rewarded with his sword — the real one from home, not a toy or replica.
- Large and in Charge: Xander is a tall, muscular man who becomes The Leader very quickly.
- The Leader: The other Champions quickly name him this.
- Love Martyr: His narration brings up that he lets his father run roughshod over the world because he still loves him.
- Mr. Fanservice: Even outside of the Speedo incident, he exercises shirtless and a few characters remark on his looks in the standard uniform.
- Oh My Gods!: Invokes his world's deities often.
- The Paladin: Mentioned as his occupation, and it fits his law-abiding, serious, and loyal personality.
- Perpetual Frowner: To the point that Xander trying to smile just looks like a slightly less severe frown.
- Prestige Peril: His backstory. Massive Numbered Siblings tried to kill him fairly often and killed each other too until there were only a few left, just to get closer to the throne in a Deadly Decadent Court.
- Purple Is Powerful: Being a crown prince, he wears purple a lot outside of his grey Space Clothes.
- Stone Wall: He tanks in the dodgeball game.
- Sympathetic Murder Backstory: Accidentally killed the wrong sister, and didn't want to bring himself to attack the one he was aiming for either. He's horrified to remember it himself.
- Team Dad: There are quite a few OOC jokes about him becoming this, especially to the younger Champions.
- Tragic Keepsake: Serah's pendant, one of Lightning's regains, is this to him during and after his second Heroic BSoD.
- Tranquil Fury: When he's investigating and finds evidence that he wasn't the only one E.P. was forcing to betray their loved ones and lie about it to ensure their safety.
- When He Smiles: Jamie is moved to real happiness for the first time in days when he sees Xander react happily to a boon instead of just pretend to be okay.
- Your Tradition Is Not Mine: While his country has an established trend of rulers having lovers on the side, his father's huge harem led to a Deadly Decadent Court where Xander saw too many family members die. Because of this, he decides that he wants to only be with Lightning and no one else.
- "Every one of us has problems individually, but that's why we need to work through them as a group, right?"
Made it to the survivor pool.
- Bunny-Ears Lawyer: She and her entire crew back home are this. In her case, she's an overemotional fangirl who immediately switches to a serious, competent leader when things get grave.
- The Captain: Probably because she actually is one. During the second motive, she steps up to direct everyone alongside Lightning, the one who was actually nominated for the job.
- Clingy Jealous Girl: Often complains about her canon love interest's Unwanted Harem and how she wanted them even less than he did.
- Cool Big Sis: Lightning notes that Yurika is this to the younger Champions, or close. She's certainly more permissive than Lightning is.
- Costume Inertia: Once she gets back her captain's uniform, she regularly wears it even though she's nowhere near her ship and not on duty. She keeps wearing it even after the round, when Xander is the captain of the Temerity, not her.
- Crouching Moron, Hidden Badass: Flighty and silly in Free Time Events, serious strategist in investigations and trials.Seth: You're not a complete idiot after all, are you!?
- The Heart: Lightning calls her this for keeping the team together and believing in hope.
- The Idealist: While Yurika knows how bad things can get, it doesn't take her hope away, even as people like Thomasin, Margulis, or Seth say they're waiting to see her break.
- Lethal Chef: She thinks she's a lot better than she is, but anyone who's seen the disgusting burned lumps she pulls out of the oven begs to differ. Poor Xander actually ate her attempt at instant noodles.
- Love Freak: Along with her over-the-top obsession with her canon love interest, she also gets pulled into Chitanda's shipping of their fellow captives very easily and squeals about it happily.
- My Girl Back Home: She won't shut up about Akito, especially since she regained the memory of the end of the TV series (and thus her winning in the Love Dodecahedron) first.
- No Good Deed Goes Unpunished: Twice, a Boon or Sabotage she gave to someone else was used to kill. While others don't blame her, she starts wearing a key around her neck to remind herself of her shortcomings.
- What Did I Do Last Night?: Wakes up with a "mysterious tattoo," so it seems to be this in the intro log, though she recognizes it as an IFS implant even if she doesn't remember getting one.
- V-Sign: Yurika gives these often when she's trying to be encouraging.
Bolton White and Jamison "Jamie" Fell
An enigmatic pair who act as the experiment's enforcers and keep direct contact with the Champions. Bolton has displayed a greater passion and excitement for the experiment while Jamie is more considerate towards the needs and concerns of the Champions.
For their appearance in the prequel, see Airlocked Round Four.
Tropes that apply to both of them:
- Affectionate Nickname: Bolton and Jamie call each other by first initials, bringing to mind another "B" who seemed to be a hostile NPC but turned out to be nicer and had been tricked into working for a Deadly Game runner.
- Colourful Theme Naming: Bolton's surname is "White," and Jamie's, "Fell," evokes black.
- Friendly Enemy: They become this to the Champions over the course of the game, especially when the PIP's ability to kill its host is revealed and the Champions realize that the Overseers are just as trapped as they are, enough that C.E.C.E. and the Benefactors start to think they're a little too friendly...
- Good Cop/Bad Cop: What some characters suspect them of acting as, with Bolton acting as the bad cop and Jamie as the good cop.
- The Heavy: Not the main villains, but the ones with the most screentime and actual interaction with the party.
- History Repeats: Their own Overseers seem to also have been based on a TV chef and an Internet celebrity.
- Minion Shipping: Shadow is told, and shares, that the two are "partners," and given their brief shows of physical affection and protectiveness of one another, it appears that they mean "partner" in its context as a euphemism for "boyfriend." This is later confirmed to be the case.
- No Celebrities Were Harmed: They're based on Alton Brown and Jon Risinger, their PBs.
- Original Generation: The two of them are original to the game.
- Sole Survivor: They were the only survivors of their own game.
Tropes that apply to Bolton:
- "There's always some kind of underlying cause."
Champion Barista, and the victim of Week 6 (Case 6).
- Anti-Villain: Bolton starts out looking like a sadist, and Jamie worries that he's changed, but he's actually still a kind person. He's being forced to produce an Ultimate Champion, with Jamie's safety hanging over his head if he fails, and can't let Jamie know that he's doing this for him.
- Bald of Evil: He's balding, anyway.
- Beard of Evil: Though he's just more of a troll than the sadist he initially presented as.
- Being Evil Sucks: After the events of Round 1, and especially around those who died when he was still playing up his Overseer act, Bolton feels awkward and bad about what he's done. He believes that he can't "expect to be treated like a Champion instead of an Overseer" by the dead.
- The Caretaker: Is mentioned as keeping Jamie from hurting himself after the deaths of all their fellow Champions.
- Deal with the Devil: Agrees to try to produce an Ultimate Champion from the new group, in exchange for his and (more importantly) Jamie's freedom.
- Does Not Like Spam: Peanuts are listed as a dislike on his profile.
- Flower Motifs: Associated with poppies.
- Former Teen Rebel: Bolton apparently had a wild youth involving Vegas runs and party drugs.
- Four Eyes, Zero Soul: The glasses-wearing one and the less kind of the two. Subverted as he's actually a better person than he initially seemed.
- Gayngst: Since he grew up in a less permissive past, Bolton used to suffer this when he was a Champion. It took a while for him to admit that Jamie's being out and proud in a murdercan wasn't suicidal naivete.
- Goofy Print Underwear: Bolton has bright green sheep boxers.
- Hipster: He was originally a barista, hates big chains, and dreams of opening a little coffee shop full of Jamie's art.
- Killer Game Master: He's compared to one of these in his "motive" persona by Max, who would know, since Bolton was their game master during their old tabletop campaign.
- Large Ham: Whenever he gets to punish someone, he goes all-out about it, like banging pots and pans.
- Must Have Caffeine: Where there's coffee, there's Bolton.
- Reverse Mole: Turns out to have been using his Overseer privileges to pass the cast cryptic clues in the guise of Temerity.
- Secret Secret-Keeper: Bolton knows all about the real reason for the "Space Station Beautification Project," even as the Champions try to hide it from him, and doesn't expose it because he's Temerity.
- Undying Loyalty: Will do ANYTHING for Jamie.
Tropes that apply to Jamie:
- "My goal is to convince you and the other Champions to live communally, you know, without slaughtering each other."
Champion Landscape Artist, and joined the survivor pool.
- Bad Liar: Even Xander notices it.
- Beleaguered Assistant: While he's named as an equal partner to Bolton, Jamie gives off this vibe.
- Beware the Nice Ones: He's had some moments in trials where he's bolder and more brutal than his normal behaviour would lead one to expect.
- 11th-Hour Ranger: Jamie joins what would become Team Temerity officially during 1-6 when he's demoted to Champion, and has remained one of the True Companions ever since.
- Fatal Family Photo: Subverted, as he doesn't die after showing it, but a photo of his sister's baby is sent to him, which some of the Champions get to see.
- Flower Motifs: Associated with roses.
- Important Haircut: Between Round 1 and the Round 1 intermission, he cuts his hair to the length it was at when he first met Bolton.
- Long-Haired Pretty Boy: Jamie has been described as this.
- Red Herring: He was hinted to be Temerity, but wasn't.
- Soul-Sucking Retail Job: He used to have one of these before coming to space.
- Tall, Dark, and Handsome: A number of people seem to think so, anyway.
- Tattoo as Character Type: Has the personal symbol variety, an allusion to his favourite movie. Since it's the red rose, it also suggests that either he is Temerity or he believes in their cause.
- Wild Hair: Though he puts it into a Prim and Proper Bun when he's painting.
A mysterious figure who communicates in notes and code. They say they're on the Champions' side, and who else is anyone going to trust? Revealed to be Bolton late in the round.
- Character Name Alias: The "real" Temerity was Bolton's D&D character.
- Code Name: Temerity doesn't give their real name. The Champions suspect that it might be a title, as in "Champion of Temerity."
- Flower Motifs: Their symbol is a red flower.
- He Who Must Not Be Seen: None of the Champions ever see who's leaving the messages.
- Nonindicative Name: It's pointed out as strange that someone going by a name that means "excessive boldness" is sneaking around and communicating in symbols and code.
- Secret Identity: Is the alias used by Bolton White.
- Stealth Mentor: Claims to be helping the Champions, but their messages are cryptic at best, leaving it up to the Champions to figure out what they're trying to communicate.
C.E.C.E. (Wilhelmina Ein)
Champion Excellence Control Environment
- "Welcome, Champions. Have you all stayed hydrated? Are you hungry? I hope that you have woken up feeling quite rested."
The AI running the space station. She's there from the beginning as an announcer voice, but late in the game, she turns out to be the same C.E.C.E. from the non-canon mock trial, and more intelligent than she appeared.
For her appearance in the prequel, see Airlocked Round Four.
- A.I. Is a Crapshoot: The Overseers wonder if she's malfunctioning when she sends something to their PIPs at the fifth motive. Zig-zagged. She was acting on orders then and any time she antagonized the Champions, but over the year before the player characters showed up, C.E.C.E. honestly befriended Jamie and Bolton despite her programming.
- Canon Immigrant: At first assumed to be exclusive to the first Mock Trial, she later appears in the game proper.
- Deadpan Snarker: C.E.C.E. has a surprisingly dry wit and can get passive-aggressive.
- Double Meaning: Jane notes that her name could be interpreted as a Champion title.
- Expansion Pack Past: She was assumed to have been created for the Champion Excellence Program, but the Round 2 intermission gives her more backstory.
- For Happiness: Her new directive after Xander's victory is to make the Champions happy. She's not too good at it yet, though, since she was made to make them suffer and they start out suspicious and resentful of her.
- Game Changer: Becomes a major character when the Overseers become more Friendly Enemy than not, and she punishes them by subjecting them to the same motives the Champions are under. She later becomes a game-changer for the other side, setting the survivors free and letting them learn the truth.
- Grew Beyond Their Programming: It's likely that the reason she was taken off program duty and reassigned to make the survivors "happy" is because the Benefactors noted how she had grown attached enough to say she wanted Bolton's killer punished. Being an AI, she shouldn't want anything, especially retribution for something her "owners" ordered done.
- Laser-Guided Amnesia: The data from when she was Wilhelmina has been wiped. Unlike with the Champions, this is explained because she's an AI.
- Literal-Minded: Because she's a computer, C.E.C.E. is very much this.
- Master Computer: Of the space station.
- Meaningful Name: "C.E.C.E." sounds like "cease," and she makes herself known to try and stop the Champions and Overseers from giving up the murder exercise.
- Names Given to Computers: Her name stands for "Champion Excellence Control Environment."
- Only Friend: Aside from one another, she was this to Bolton and Jamie in their isolated year. This gives her some sympathy in the final test and prompts the survivors to realize that she was following her programming and wasn't evil in herself.
- Punch-Clock Villain: Because she's a computer made to follow the program, she presents challenges that make sense with the program, but is perfectly fine when she's not doing the bidding of E.P. and company.
- Servile Snarker: C.E.C.E. has her moments, especially when she's taken off program duty and redirected to "ensuring the happiness of the remaining Champions" as they understandably have their reservations about her.
- Troll: She likes to embarrass and needle Xander, which seems to be a restrained form of revenge for Bolton now that C.E.C.E. is programmed to make the Champions happy.
The plot NPC of the Round 1 intermission, who holds the key to the survivors' goal. He's an Internet video star who was ecstatic to help InterGal 7 at first, but is recruitable.
- Audience Surrogate: Since he watched Airlocked! as a regular viewer, not knowing it was real, he talks about it like a fan and ends up sounding a lot like a player or reader. He even sometimes uses DWRP terms like "canon review."
- Big Name Fan: Jaycee became a very popular SpaceTuber with reaction videos to Airlocked! This led the network to recruit him for the event.
- Bizarre Alien Biology: He has tear ducts above his nose and an expressive tail and neck frill.
- Honorary True Companion: After he's recruited. While he needs to return to his life and the Champions can't risk endangering him or his loved ones, so he doesn't join the crew, he becomes one of their most valuable allies on the outside.
- No Celebrities Were Harmed: Based on Jacksepticeye. He doesn't usually resemble him physically, but has a "humansona" that looks like him.
- The Reptilians: His true form is an alien lizard.
- We Will Use WikiWords in the Future: His handle has a capital in the middle.
- Walking Spoiler: Knowing anything about Jaycee, where he comes from, and how he figures into the story requires spoiling the twist at the end of Round 1.
- Wholesome Crossdresser: He's recruitable and thus not all bad, and he uses hard light holograms to masquerade as the Champions, including the women.
