Be warned: There are unmarked spoilers below.
FriskThe human child who fell underground and eventually managed to free the monsters trapped there. They now act as monsterkind's ambassador. They are an ardent pacifist and are determined to never hurt anyone.
- Actual Pacifist: They will not hurt anyone, nor will they allow anyone to be hurt if they can help it. Word of God is that they do make an exception for video games where it's impossible to win without killing anyone.
- Averted in the AFAC Hunger Games, where they end up tied with Papyrus and the Nicecream Guy for highest number of kills, with four (Of course, In-Universe it's apparently a game they're playing).
- All-Loving Hero: Wants to save everyone, including Chara.
- Ambiguous Gender: Frisk identifies as agender, though their assigned sex is male.
- Anger Born of Worry: Yells at Monster Kid for putting himself in danger to get Frisk's attention.
- The Atoner: The reason why Frisk has a strict Thou Shall Not Kill policy is because they (subconsciously, at first) remember letting Chara use their body to kill nearly everyone in the last timeline.
- Big Little Brother: Towards Flowey, who is older than him even with Mental Time Travel in play, but still a plant in an easily-carried pot. Averted after Flowey becomes Asriel again, and is the same height.
- Do Not Call Me "Paul": Frisk's given name is Bronson Torres. Word of God confirmed that they do NOT like to be called Bronson.
- Driven to Suicide: During Chara's genocide run in Frisk's body, Frisk took control and committed suicide to perform a true reset before they could kill Sans.
- Empowered Badass Normal: Learns to create a personal barrier spell in the fourth arc, ¡Eclipse Total!
- Eyes Always Shut: Subverted. It seems like this for a while, but when asked about it, Frisk reveals that their eyes are open they just have thick eyelashes.
- The Gadfly: Had a lot of fun needling Sans and Toriel about their mutual crushes.
- Mundane Utility: Back during the events of the game, they rewound time multiple times just so they could eat Toriel's pie over and over again.
- My God, What Have I Done?: When Frisk regained their memories of the time Chara took control of their body and did a genocide run in it.
- Oblivious to Love: They only realize that Monster Kid was flirting with them long after the fact. They're horribly embarrassed when they do figure it out.
- Red Eyes, Take Warning: When possessed by Chara. They're normally green.
- Also happened when they summoned a magical barrier.
- Take a Third Option: When asked what their favorite kind of dog was in order to try calming them down from Janet realizing they're Susan's kid and were afraid she'd tell Susan they're alive. They said that all of the dogs were their favorite, since they were afraid that if they chose a favorite kind of dog, all of the dogs would be sad.
- The Determinator: They never give up on helping others, even after they tried to kill them previously. They resolved to solve things peacefully.
- The Runaway: They became this after their Abusive Parents kicked Aidrian, their older sister, out of their house.
- Trauma Button: The abuse Frisk suffered through caused them to be deeply upset by a few things that may seem innocent.
- They are deeply afraid of being faced with the possibility of going back to their human parents.
- Because Susan burned Frisk's favorite card in front of them, this actually spawned 2 triggers for Frisk.
- The scent of burning.
- The click of a lighter.
- Because Susan yelled at Frisk for accidentally dropping a carton of eggs, they are triggered by the sight of broken eggs on the ground.
- Susan belittled Frisk's interests in manga when she asked them what they were reading, so they are afraid to be asked what they're reading.
- Frisk can be triggered by being deadnamed and misgendered. This happened constantly in Susan's household.
- Set Right What Once Went Wrong: After Chara's nearly-completed genocide run, they temporarily retook control and stabbed themself in the heart so as to reset back to the beginning of their adventure and do it the Actual Pacifist way.
- Shipper on Deck: An ardent Soriel shipper.
SansA lazy skeleton from the Underground that has a lot going on in the background.
- Badass Boast: When one asker asked how powerful he was, he simply responded that if we ever see him at his full power, one of us was definitely going to die.
- Berserk Button: Flirting with Toriel will earn you a "Wanna have a bad time bro?" from him. Hurting Papyrus is another. Adrian got off light because it was a misunderstanding. She was not, however, off the hook. For misunderstandings, he can be seriously petty.
- Chara in general. When the alternate drunk Chara showed up, Sans almost attacked on sight before Asgore stopped him. And again when his world's Chara got themselves a body.
- Cannot Spit It Out: Towards Toriel.
- 11th-Hour Superpower: Sans got upgraded to his memelord form by the askers to boot Chara out of his mind.
- Everyone Can See It: His crush on Toriel. Papyrus can see it and tries to get him to act on it.
- Heroic Willpower: Temporarily grabs control of himself back from Chara using this.
- My God, What Have I Done?: Sans felt horrible for having a sexy burger dream while Toriel was feeling depressed. He was really more Innocently Insensitive than anything else.
- Note to Self: After promising to truthfully answer a question that turns out to be "So... my mom... Would you kiss her and do gross mushy stuff with her if you knew she was down?"*note to self.—sans
- One-Hit Point Wonder: As in canon, much to Chara's surprise and annoyance. Even as a memelord.
- Pungeon Master: Loves puns.
- Real Dreams Are Weirder: Both dreams of his that the askers get to see.
- Red Eyes, Take Warning: His eyelights turn red when he's possessed by Chara.
- Sad Clown: When possesed by Chara, he admits that he's always had a hard time staying positive.Sans: *i mean, why do you think i tell so many jokes?
- Super Reflexes: They help a lot at winning fighting games.
TorielFormer queen of monsters and Frisk's adoptive mother. Sweet and motherly, but she does have some issues under the surface.
- Action Mom: Kicks the most butt of any of the monsters during the first arc other than Sans.
- Armor-Piercing Question: "Hey mom? Did you know that Sans thinks you're hot?"Frisk, after the Dramatic Drop and blush from Toriel: Good news Sans. She's down.
- Fan Nickname: Askers often refer to her by variations on 'Goat Mom' (a common fan nickname for Toriel).
- I Can't Believe a Guy Like You Would Notice Me: She doesn't believe that Sans would be in love with an 'old lady' like her.
- Is This Thing Still On?: She's the reason Asgore is called "King Fluffybuns" she was making an address and then forgot the mike was still close to her face when she handed it over to Asgore for his speech.Toriel: Your turn, fluffybuns!
- Mama Bear: The woman No Sells Chara!Sans' bone attacks to defend Frisk and Kid.
- Also takes the blast when Goopster attacks Flowey.
- Oblivious to Love: She thinks that Sans only sees her as a friend. Until the askers took matters into their own hands and flat-out told her.
- Purple Is Powerful: She's associated with the color purple and has purple eyes.
- Stepford Smiler: She became this after the Red Echos arc.
- Supreme Chef: Makes great pies.
Flowey/AsrielAs Asriel, he was Toriel and Asgore's son and prince of monsters. Now he exists as a soulless flower who doesn't have much of a concept of positivity (though he is getting better). During the Red Echoes arc, he regains a small part of Asriel's soul. The rest of Asriel's soul is with Chara, as shown when ClimaxStriker and several other askers correctly guess where it was and manipulate Chara into drawing it out. Asriel's first in-person ask-answering appearance is when the askers spy on Callallied's dreams.
- Alternate Self: Knows Maverick is this to him, calling it obvious when the askers noted it. Also, while Flowey is out and about, most of Asriel's soul remains attached to Chara with the eventual reveal that Asriel can be active within Chara's mindscape.
- Berserk Button: As of the Sweet Dreams and Nice Creams Arc, hurting Frisk. When he heard about the Abuse Frisk lived with before they went to Mt. Ebott, he asked Frisk where their parents lived with an honest to god Slasher Smile on his face.
- Being reminded of his "Kill or be killed" past really sets him off.
- Hurting Toriel is this, too. He's furious when Goopster nearly kills her after she protects him.
- Big Brother Instinct: On occasion, displays this towards Frisk, and even with Mental Time Travel in effect he's probably the older of the two. However, while he's Flowey, Frisk is the Big Little Brother.
- Brutal Honesty: Emphasis on the 'brutal' part.
- The Cutie: As Asriel, he was this. Not so much as Flowey. When Asriel finally appears in person, he shows that he definitely still is.
- Glass Cannon: According to Chara's Check, he has 19 Attack (higher than half the group) but 0 Defense.
- Jerkass: He is much more this since joining Frisk's band of friends. Since finding out about his little soul shard, he's been getting better.
- Nightmare Face: As in canon, he's prone to these, however since he's on the heroes' side the worst it means is that he's either about to say something very cutting or lash out with his pellets. After finding out Frisk's tragic backstory, he's started pulling it on on Frisk's behalf.
- Momma's Boy: The first sign that some of his soul has returned is the sheer fury he felt at seeing someone hurt Toriel.
- Planimal: After regaining his soul, Asriel has wooden horns as opposed to the more natural-looking horns of his parents or his appearance as a disembodied SOUL. Sharp-eyed viewers will notice that Maverick has, and always has had, similar wooden horns.
- Reformed, but Not Tamed: He may be willing to leave the rest of the household alone most of the time, but he's still not a nice person and a full emotional spectrum is well beyond him even once some of his soul is back.
- The Soulless: As in the game, the main reason he is the way he is. According to him he can only feel two things: basic survival instinct, and satisfaction at beating others at Smash Bros. Subverted to a point since we found out he has regained a tiny bit of his own Asriel soul. This enables him to feel guilt over his actions and emotional attachment to people/things, but is nowhere near enough to actually be Asriel again.
- It was almost completely subverted when a group of Askers cooked up a plan to return the rest of his soul, but it didn't work, and then later gets his soul fully back after Chara's transformation.
- Sir Swears-a-Lot: Prone to this when angry.
AsgoreThe king of the monsters; his life has been going up since Frisk saved his kind, though he still has a few things to work through.
- Curb-Stomp Battle: Was once on the receiving end, with Toriel on the giving end (he was really arrogant when he was young).
- Demoted to Extra: Probably the least-seen of all the household members, only showing up briefly in the first two seasons. Season four starts featuring him more.
- Gentle Giant: A very big goat and a total sweetheart.
- Nice Job Breaking It, Hero!: Though the problems it caused were nothing he could have foreseen, he gave Gaster orange scented tea, which piranhas were attracted to. Guess what the river Gaster fell in was filled with?
PapyrusSan's brother, a cheerful and bombastic skeleton who you have to try really hard to tick off.
- All-Loving Hero: Papyrus doesn't have a single bad bone in his body when it comes to others. When a creep hit on and misgendered Mettaton, Papyrus was there to calm down the situation with friendliness and understanding, even getting the creep to admit he'd been a jerk and see the error of his ways. This is part of why Mettaton fell for him.
- Anger Born of Worry: Papyrus looked pretty pissed off after Sans pretended to be stabbed by Chara when the knife hit the ketchup bottle. Subverted once he just holds Sans up and tells him that he is not allowed to do that ever again.
- Beware the Nice Ones: Papyrus went into Berserker Tears after Sans was stabbed by Chara. When you see Papyrus get truly angry, you will know just how much restraint he's been showing since the moment you saw him.
- Let's Get Dangerous!: Decides to really step up to the mat when Undyne denies him Royal Guard membership by claiming he's too nice. Being nice doesn't mean he can't fight for what he believes in, and he gives her hell in the ring after challenging her for leadership of the guard.
- Memetic Psychopath: In the AFAC Hunger Games, where he gets four kills (the same number as the first- and second-place finishers), the first one being Toriel.
- Nice Guy: As always, a defining charactaristic of his. He'll even comfort a distraught Flowey or immediately forgive the person who punched him unprovoked! However, it's used against him when Undyne denies him membership in the Royal Guard by claiming he's too nice.
- Not Helping Your Case: He almost gets himself attacked by Aidrian again when he describes his (canon and perfectly innocent) date with Frisk in Accidental Innuendo after she was already freaking out about how the ten-year-old Frisk was getting into rather adult situations.
- Unwitting Instigator of Doom: Plays this part in the Extra Dark Chocolate Arc. Telling Flowers, Braids, Twinkie, and Harlow about Aidrian's assault on him starts a Cycle of Revenge. And as Maverick reveals, if Aidrian died, the trope would reach near Exaggerated levels with it being a catalyst that nearly destroys the universe.
UndyneCaptain of the Royal Guard before it was disbanded, and now lives with the human she once tried to kill.
- Action Girl: She's not captain of the guard for nothing.
- Blood Knight: Loves fighting.
- Butch Lesbian: She's the Blood Knight captain of the guard and is in a relationship with the female Alphys.
- Curb-Stomp Battle: Deals one out to Maverick.
- Eyepatch of Power: She got it when her eye was hit with debris when the Core exploded.
- Large Ham: Her method of accepting Alphys's proposal involves leaping out of a ferris wheel while it's still in motion to get the ring when it was accidentally thrown out the window (that she broke earlier on).
- More Dakka: Has this philosophy with spears. She thinks that if she hurls enough of them, then her enemy won't be able to dodge despite her lack of depth perception. Frisk can, but only after resetting enough to memorize her attack patterns.
AlphysThe former Royal Scientist; an anime aficionado and Undyne's girlfriend.
GasterSans's and Papyrus's father; a brilliant scientist who accidentally erased himself when he fell into the Core. Sans used his power to rip him from the void, and he now exists just as he did before.
- Beware the Nice Ones: When Chara sees the group's stats, his (66 ATK and DEF) are the third-highest in the group, behind Toriel and Asgore (both of whom have 80 ATK and DEF), and far above the next highest scores (Flowey's 19 ATK and Alphys's 3 DEF).
- Driven to Suicide: It's very heavily implied that Gaster's fall into the core was a suicide attempt.Asker: Am I the only one who thinks Gaster didn't "accidentally" fall but rather ... "Willingly fell" if you catch my meaning.Asker (to Hermann): Don't you ever wonder how a genius could fall 'accidentally' into his own creation, which he designed himself? Maybe it was too much for him. Maybe he told himself that his sons would be better off without him. Maybe he jumped.
- Lovable Nerd: He's an adorable science geek.
- Mad Scientist: Became one after the death of his wife. The guilt from this seems to have driven him to erase himself. His wife also chews him out for this upon meeting him again.
- My God, What Have I Done?: Gaster had this after his wife, who was revived from a previously thought failed resurrection experiment, gave him a scathing What the Hell, Hero? speech.
- Oh, Crap!: Had this moment when he realized that he drank orange scented tea with Asgore when he was in a river with orange-scent-seeking Piranhas.
- Shipper on Deck: He knows about both of his boys' crushes, and ships them.
- Spanner in the Works: His ability to teleport gets him and the rest of the group to the scene in time to pull a Big Damn Heroes against Chara!Sans.
- Tears of Joy: When Sans pulls him back into reality.
- Teleporters and Transporters: He can teleport, though he doesn't like to do it.
- Troubled Fetal Position: When he's reminded of just how bad he used to be.
The River Person/HermannA mysterious figure who wanders the rivers of the Underground whilst saying cryptic phrases. Her true identity is Arial Hermann, Gaster's wife, who died but was brought back by Gaster's experiments.
- Demoted to Extra: Her importance dropped significantly since Sweet Dreams and Nice Creams.
- Gratuitous Spanish: Speaks in Spanish occasionally.
- Late-Arrival Spoiler: Premieres in the first proper story arc, and not exactly kept hidden in later arcs.
- Shipper on Deck: For Frisk / Monster Kid.Asker: *meanwhile River Person is hardcore shipping the two cinnamon rolls in the backgroundRiver Person: Actually, right now I'm shipping the two cinnamon rolls in the foreground.
- The Soulless: She was revived by Gaster performing the same kind of Determination injection that led to Flowey/Asriel's rebirth in Undertale canon. Ultimately subverted, she regained her soul long ago but she didn't realize it. It was because of Gaster's hypothesis that she fooled herself into thinking that she was soulless.
ChillerA Gaster Blaster; once the companion of MWSIH!Gaster. His resemblance to a dog spawned Frisk's affection for him.
- Badass Adorable: A cute skeleton puppy who's also technically a Gaster Blaster and just as powerful as any other.
- Canon Immigrant: Quite literally. Chiller was created for the Man Who Speaks In Hands blog but ultimately jumped ship following the crossover.
- Ridiculously Cute Critter: Became an adorable skele-pup whose honor as cute will be defended not only by askers, but even by Flowey.
- Talking Animal: After an asker made it so.
MettatonA ghost-turned-robot; the monster community's biggest celebrity. Lives at his own apartment complex instead of at Frisk's house.
- Bad Liar: About his crush on Papyrus.
- Berserk Button: He really doesn't like it when people address him as a "She" and not a "He."
- Camp Gay: Identifies as male, is in love with another male, and is incredibly feminine.
- Cannot Spit It Out: He wants Papyrus to be the one to ask him out, to confirm that Papyrus sees them as equals.
- Demoted to Satellite Love Interest: Downplayed, his personality is still there and he has relations outside of his relationship. However, in the original game, he was a major character; here, most of his screentime is devoted to his relationship with Papyrus.
- Fiction 500: Rich enough to have built both his own luxury apartment building (of which he and his counsin occupy the penthouse) and a massive monster-themed amusement park in a year. By comparison, the royal family of his people live in a house with several other monsters and explicitly have jobs that don't even offer paid vacation days.
- Impossibly Tacky Clothes: The outfit he wears to impress Papyrus.Asker: Mettaton what in the WORLD are you wearing??Other Asker: you look like the 60's, 70's, and 80's all threw up on you at once.
- Interface Screw: Apparently, he can kick asks out of existence.
- Saying Too Much: About his crush on Papyrus, complete with an Oh, Crap! face once he figured out what he said.
- The Nicknamer: Tried to claim he was this when called out on reffering to Papyrus as "Papy." Only to be undermined when the only nickname he could think of was calling his cousin "Blooky."
- Throw the Dog a Bone: He finally throws one Burgerpants' way when Burgerpants fills in for the injured main actor of Mettaton's stage musical and kills it. He even shows concern over his beleaguered employee's health when he collapses from exhaustion due to both the exertion of playing the role and the fact that he'd squeezed his chubby frame into a rigid costume meant for someone much thinner.
Monster KidAn armless monster child who Frisk encountered in the Underground. Later developed a crush on Frisk.
- Berserk Button: See Violently Protective Girlfriend.
- Burning with Anger: He was breathing fire after he had enough of askers blaming Frisk for Sans getting stabbed. It also happened after a kid mocked him for being in a relationship with Frisk.
- Violently Protective Girlfriend: Inverted and Downplayed. Monster Kid is referred to with male pronouns and is not normally violent, but he will be angry if you threaten or insult Frisk.
Maverick Chaosdragon, The Shadow Rogue/Future AsrielA boss monster from another universe who arrived in the world of AFAC with an unknown goal. Also a total dork who can't really pull off the 'dark and mysterious protector' thing as well as he thinks he can.
- Alternate Self: To Flowey/Asriel via dimension-hopping.
- Bad Liar: He did not do a good job trying to deny it when the askers speculated that he was Asriel.
- Bait-and-Switch: When an asker asked if either Sans or Asgore was his father, Maverick said they both were, before bursting into laughter and saying "Naaah, I'm Asriel. Not this universe's Asriel though. My parents are Toriel and Asgore. Same as this universe's Asriel, as far as I'm aware."
- Berserk Button: Laughing at his name.
- Big Damn Heroes: Arrives to save Flowey from Chara (possessing an alternate version of himself) after Chara fell for a group of askers telling him that Flowey had become the Absolute God of Hyper-White-Chocolate in an attempt to give Flowey Asriel's soul back.
- Continuity Nod: His weapon is listed as 'Chaos Saber', which is one of Absolute God of Hyperdeath Asriel's attacks in the final battle of Undertale's pacifist route.
- Eureka Moment: Immediately figures out Chara's plan after being told they've dug up at least one body from the Underground. Despite this, he stays mum on what that entails for the moment.
- Expy: Of Future Trunks, as a kid from a bad future who went back to the past to prevent a death that leads to a chain of events ending in his bad future.
- Goggles Do Something Unusual: His armor is listed as 'Swim Goggles'.
- Highly Visible Ninja: Despite looking and acting like a ninja, so far he's been caught sneaking around multiple times and has even been captured by the main cast. At the start of season four Frisk outright calls a loud hello to him when he's trying to "guard from the shadows."
- Interface Screw: He has the power to talk over the narrator, replacing blunt and unflattering descriptions with more favorable ones. He can also obscure his stats (well, until Undyne beats him uncosncious).
- Kid from the Future: Though its relatively obvious, hes an alternate future Asriel. However Frisk intially assumes him to be from a universe where he's Sans' and Toriel's son.
- Set Right What Once Went Wrong: This seems to be his reason for being in this dimension.
- Shell-Shocked Veteran: He apparently has some PTSD from whatever happened in his home universe. This prevents him from fully integrating into the family as he's still working out his issues.
- Walking Spoiler: While it's a poorly hidden secret that he's an adult version of Asriel (complete with a soul)]], his exact reasons for being in this dimension can spoil a major twist in the Extra Dark Chocolate story arc. We also still have a Flowey (with a small piece of his soul) that is, by boss monster standards, still a kid. This suggests that Flowey can get his soul fully back. And many details of his backstory still remain a mystery.
- On the other hand, he multiple times admits there are obvious differences between his world and this one that he had no effect on—Chara's posession plan before he even showed up, for example, didn't happen in his world. In addition unlike him, this world's Asriel doesn't grow up after getting his soul back and remains a child, as does Chara, whereas Maverick's Chara was also depicted as a teenager.
NapstablookMettaton's shy cousin who is now in a band with him.
- Apologizes a Lot: As in canon. They're initially set off by accidentally informing the askers that Mettaton has a crush.
- Satellite Character: Mostly around for Mettaton to have someone to interact with when he's having scenes at his apartment building.
- Screw This, I'm Out of Here!: Quickly leaves when they realize Metta and Papyrus are having a moment.
FlowersA member of the gang that attacked Aidrian and a popular pro-wrestler at the Pit. Rash and swift.
- Face: Her pro-wrestling persona is a Bully Hunter, and her real life actions imply she is too. Her conflict with Aidrian is from a complete misunderstanding of that time Frisk's sister kicked Papyrus in the face.
- Fragile Speedster: Sure, she may be too fast to dodge, but give her one good smack to the face with a frying pan and she's down for the count.
- Jerk with a Heart of Gold: She's abrasive and can come off as supremely rude, especially with a harsh comment to Frisk that amounts to her not considering them "her ambassador". However she's a legitimate Bully Hunter and her comment was more from a place of disdain towards Frisk being placed in a position of government instead of being able to focus on their childhood.
- Shock and Awe: She uses electric magic in combat.
- When All You Have Is a Hammer...: Much to the exasperation of her friends, she considers fighting to be her "hammer".
BraidsA member of the gang that attacked Aidrian. Quick and deadly.
- An Arm and a Leg: Aidrian had to chop his arm off with a frying pan gifted to her by the askers in order to save Jason from being choked to death. It's not coming back.
- Disproportionate Retribution: He was going to choke Jason to death just for being the reason that Aidrian attacked Papyrus. It's later revealed that since Braids doesn't have to breathe, he just didn't remember that humans do.
TwinkieA member of the gang that attacked Aidrian. The bulkiest of the group.
- The Big Guy: He's physically the biggest of Harlow's group. However, he's not much of a bruiser.
- The Heart: He's very sensitive, being worried about his friends' mental states.
Harlow GaramondA skeleton who once served in the Royal Guard. Justifiably angered by how some humans harass monsters, but sometimes takes their anger too far...
- Canon Immigrant: Harlow Garamond was originally a character created for Man Who Speaks In Hands. This universe's version has a very similar design and backstory, but a few key differences (this HG was not the riverperson, is not related to Gaster, and is not The Atoner (yet).
- Disproportionate Retribution: It's stated that he 'repays all favors two-fold'. He was going to flat-out kill Aidrian and Jason for hurting Papyrus and lopping off Braids's arm. Jason didn't even do anything except cause Aidrian to attack in his defense!
- Half-Truth: During their retelling of the events that occurred last night, they tell Undyne about how Aidrian cut off Braids' arm in the fight, but didn't mention that Braids was choking Jason to death at the time and Aidrian did that to save his life.
- Unwitting Instigator of Doom: If he had killed Aidrian and Jason, then that senseless murder would have utterly destroyed any trust humans would have had for monsters, and led to a conflict that is heavily implied to be what ended up destroying Maverick's original universe.
FrejaUndyne's mother, who once occupied the position of head of the Royal Guard herself.
- Action Mom: Former head of the Royal Guard, and mother to Undyne (who occupied the same position herself).
- The Comically Serious: Always has a blank expression on her face.
- Killing Intent: Defied. Her ambush at the Trash Mart would have, according to her, done one or two damage at most due to her not actually intending any harm.
- Meaningful Name: Freyja is the Norse goddess associated with love, beauty, war, and death.
- Our Mermaids Are Different: She's able to move on land with no legs and a visible fish tail. Fortunately for Undyne, monster (magic) biology averts the Mermaid Problem.
- Proud Warrior Race Guy
- The Stoic: Momzy is the noisy one.
School ChildrenA varied assortment of child monsters who attend the same school as Frisk.
- Official Fan-Submitted Content: They were created by fans for a contest and became characters in this way.
CallalliedOne of several monster children Frisk and Flowey attend school with. They are a bashful skeleton monster who tries to hide their hands.
- Ambiguously Evil: While it's beyond a reasonable doubt that they're Chara, it is initially unclear if their shyness and amnesia is genuine, or just a ruse to lift suspicion. An asker visit to their mindscape seems to confirm that they really do have amnesia Chara is portrayed as asleep in their mind and it's only Asriel's efforts that keep them from going under (and presumably dying).
- Berserk Button: Gets extremely annoyed when askers threw out a few comments about white chocolate. They went on a massive rant about how white chocolate wasn't really chocolate neatly confirming askers' suspicions that they were Chara.
- Chekhov's Gunman: After a few small appearances at the beginning of the fourth arc, they become important when them being bullied and Frisk defending them leads the latter to discover their wizardry.
- Becomes important again later when they're revealed to be an alter ego of Chara.
- Identity Amnesia: After Chara's Despair Event Horizon, they seemingly lost their memories, and now they think they're genuinely a ghost monster possessing a human skeleton.
- Meaningful Name: As at least one asker pointed out outside of the comic, Callallied sounds rather similar to "Chara lied."
- Official Fan-Submitted Content: Like the rest of Frisks classmates. Subverted. In fact, Word of God states that one of the contests main purposes was to introduce Callallied in a way that didnt immediately set off alarm bells toward them.
- Our Liches Are Different: Word of God reveals that this is effectively what Callallied is Chara's skeleton, resurrected via necromancy.
- Red Right Hand: At some point, their voice changes, demonstrated for the viewers by their text becoming red. This was a clear indication that they were connected to Chara.
- Looking at their hands when they're uncovered, you can see they have five fingers. According to Word of God, skeleton monsters have only four fingers.
- Shrinking Violet: Initially appears more bashful than Alphys in the original game, if you can believe it. In truth, this is likely a combination of keeping their true nature hidden and having to choose their words very carefully.
- Walking Spoiler: They turn out to be Charas alter ego.
Jason LacasseA human who Papyrus accidentally hits with a car. Something of a dork and best friends with Aidrian.
- Crazy-Prepared: He carries SAND in his POCKETS, just in case he needed to throw it at someone in the eyes to escape. Wanna know how long it's been since he started this routine? MIDDLE SCHOOL!
- Deadpan Snarker
- Drunk on Milk: He has an... entertaining reaction to being fed a nice cream. He doesn't even realize that his broken leg (which Flowey gave him the nice cream to fix) was healed until much later.
- Ensemble Dark Horse: Askers quickly took a shine to him.
- Masculine Girl, Feminine Boy: The Feminine Boy to Aidrian's Masculine Girl.
- Noodle Incident: Still has war flashbacks to the "Christmas Fiasco."
- The Nicknamer: He nicknames Maverick with the names of dark and edgy characters such as Kylo Ren, Vincent Valentine, and Shadow The Hedgehog.
Aidrian TorresAn impulsive young woman who is quick to lash out when someone she cares about is in danger.
- Action Girl: She's a third degree blackbelt in Karate and her profession is Mixed Martial Arts fighting.
- Actually Pretty Funny: Sans doodling on her face.
- Badass Normal: See Action Girl.
- Berserk Button: Hurting her friends is one way to get your ass kicked. ALWAYS, ALWAYS, ALWAYS, USE "THEY" AS A PRONOUN WHEN REFERRING TO HER LITTLE SIBLING, FRISK. ALWAYS!!!!
- Beware the Nice Ones: First meeting aside, she's actually very kind, but mess with the people she loves and that will earn you a kick to the face.
- Came Back Wrong: In the bad future Maverick came from, Frisk and Gaster attempted to revive Aidrian with Determination. This resulted in giving her dead body life, but with her soul long gone, it succeeded only in turning it into what is best described as a terrifying cross between a traditional zombie and Undertales amalgamates, and was a major factor in what led to the bad future.
- Death Glare: Gave one to the askers when they called Frisk a "He" or a "She." Her glare is scary enough to make grown men go "Eep."
- Frying Pan of Doom: The askers gave her one, and she used it well.
- Hair-Trigger Temper: She's pretty quick to resort to violence when she thinks her loved ones are in danger. Luckily, she's quick to calm down if she sees it's a misunderstanding, and Papyrus is nice enough to forgive her.
- Has a Type: She has posters of Sesshomaru, Future Trunks, and Rock Lee on her wall. It's really no wonder she fell for Maverick, who's a pretty boy like Sesshomaru, a Kid from the Future like Trunks, and a ninja like Rock Lee.
- Hot-Blooded: Described as 'hot-headed, hot-blooded, and hot in general.'
- Late-Arrival Spoiler: Adrians intro and reveal of their relation to Frisk happened in the second arc. Though other details, such as her role in Mavericks bad future, are revealed later.
- Masculine Girl, Feminine Boy: The Masculine Girl to Jason's Feminine Boy.
- My God, What Have I Done?: Played for Laughs when she realized that she inspired Frisk's habit of flirting.Aidrian: I've created an unstoppable flirt-monster.
- My Greatest Failure: It is not hard to believe that she would count her finally snapping at her parents and breaking her mom's porcelain pig collection in a fit of rage as one; it led to her getting kicked out of the house, which, in turn, led to Frisk running away and, assuming that she knew about Mt. Ebott and the kids disappearing there, led her to believe they were dead. She really took it hard, to the point where just mentioning Frisk would bring her down from the most excited of moods.
- Rage Breaking Point: Against her parents in the backstory. After they abused Frisk one too many times, she just snapped and destroyed their porcelain pig collection.
- Rescue Romance: Fell head over heels for Maverick when he saved both her and Jason's lives.
- The Tease: Her default reaction to people making uncomfortable advances is to flirt aggressively with them to make them uncomfortable enough to stop. She also applies this to fighting to distract her opponents. This ended up rubbing off on Frisk, much to her horror when she found out.
- True Companions: She was willing to fight monsters, beings with powers that could very well kill her, to save her friend. Major misunderstanding aside, you do have to hand it to her: she's got guts to try something like that for her friends.
Susan TorresFrisk's emotionally abusive mother. One of the reasons Frisk ran away from home.
- Abusive Parents: Word of God confirms she is the more aggressive of the 2 parents. She yelled at Frisk for dropping a carton of eggs on the ground by accident. She coldly rejected Frisk's well-intended offer to clean it up, stating that they'd "only make a bigger mess". Word of God said that she threw Frisk's Pokémon cards away for not immediately cleaning their room. When Frisk dug through the trash to save one card, their favorite card, she took it and burned it right in front of them.
- Berserk Button: She will write you off her list of people to hang out with if it turns out you've written anime. She calls it "Japanese Garbage" for some reason. Word of God confirmed she was initially fine with Jason's family, but upon finding out Miu wrote Mew Mew Kissy Cutie, a manga, she wrote them off as bad eggs for some reason and decided they were a bad influence. The reason she hates anime is a mystery to us all to this day.
- Collector of the Strange: She owned a collection of porcelain pigs. The past tense is appropriate here, as Aidrian snapped and broke them all in a fit of rage.
- The Corrupter: As one anon noted, she acted like a Ku Klux Klan recruiter, targeting vulnerable people like Janet and preying upon and exacerbating their fears.
- Fantastic Racism: She is a notable member of the anti-monster protesters, and she's responsible for feeding Janet's prejudice against monsters.
- Giver of Lame Names: Named Frisk "Bronson." Even Asgore has better naming skills than that.
- Heteronormative Crusader: Really a Cisnormative Crusader, she refuses to acknowledge Frisk as agender and forces them to conform to the gender binary by doing stuff like cutting their hair despite their desire to keep it long.
- Hypocrite: In regards to the Heteronormative Crusader thing, she is clearly the more aggressive of the 2 parents and also more dominant and, according to her husband, more assertive. These are masculine traits she exhibits herself, yet she feels like making an agender Frisk "act like a man."
- At one point in Harlow's flashback, she can be seen holding a sign that says "SAVE our CHILDREN".
- Malicious Misnaming: Word of God confirms Susan knows Frisk's preferred name. She just sticks to using Bronson because she's a stubborn bitch.
- Masculine Girl, Feminine Boy: Susan is the masculine girl to her husband's feminine boy. This isn't meant to make them sympathetic, but to point them out as hypocrites.
- Nice Job Fixing It, Villain!: While nothing was "broken", per say, she's a major reason why Frisk ran away to Mt. Ebott and subsequently freed the monsters the very "demons" she is protesting.
- Wanted a Gender-Conforming Child: Her reason for her abusive behavior to Frisk.
- Unnamed Parent: used to be unnamed until Janet revealed her name while freaking out about finding her kid alive.
Frisk's Father / Mr. TorresFrisk's emotionally abusive father; One of the reasons Frisk ran away from home.
- Abusive Parents: While Susan was the aggressive type, Mr. Torres is the apathetic one. Word of God says he would often try to get Frisk and Aidrian to behave so he doesn't have to deal with his wife's bullshit. When Frisk got home from school and told their dad they got punched in the face, rather than comfort them and ask them if they're OK like a real parent would, he instead asked if they punched back.
- Fantastic Racism: Safe to assume the father is a protester like Susan. He was sighted in Harlow's flashback.
- Heteronormative Crusader: A Cisnormative Crusader like Susan. This man doesn't accept Frisk as being agender.
- Hypocrite: Also, like Susan, because he's passive, silent, and submissive due to his not doing anything to help his kids. This also makes him a hypocrite.
- Lack of Empathy: The only crap he gave about Frisk being in a fight was whether or not they punched back. That is all.
- Masculine Girl, Feminine Boy: Feminine guy to Susan's Masculine Girl. Meant as a deconstruction showing that he's a hypocrite who's backwards when it comes to gender roles, yet forces those on Frisk along with Susan.
- Wanted a Gender-Conforming Child: Same as his wife.
- Unnamed Parent: Both parents were initially unnamed, but then Janet namedropped Susan.
Janet EspinozaOne of the managers of Pedro's Pizza, where Jason works. Not exactly the most monster-friendly human out there, but she has her redeeming traits.
- Agree to Disagree: Tries to pull this when she can't think of a proper argument against Aidriannote saying that, by her anti-monster logic (she's scared of them and thinks they're too dangerous to be around), Aidrian should be banned for her body being a deadly weapon.
- Character Development: It's revealed that part of her hatred of monsters was due to her finding her ex-boyfriend making out with one, before he was her ex. This ended up being combined with Susan Torres' warnings and paranoia. After the visit to Monster World theme park, she admits she let her experiences reinforce her prejudices and is doing her best to change. She even appears to have started a friendship with Asgore the literal king of all monsterkind.
- Everyone Has Standards: When she realizes that Frisk identifies as agender and discarded their old name, she becomes very remorseful for unknowingly deadnaming and misgendering them.
- Fantastic Racism: Against monsters. Specifically, according to her reference sheet, she's afraid of them and treats them like dangerous animals.
- Freudian Excuse: Her initial Fantastic Racism was due to her natural anxieties about the monsters being fed by Susan's poisonous words and discovering that her boyfriend (who'd encouraged her to accept monsters) was cheating on her with a bunnygirl monster.
- Good Parents: She treats Noah very well from what we see.
- Glamorous Single Mother: Not much is made of the fact that she raises Noah alone.
- Hidden Depths: Turns out, she's capable of change and growth as much as anyone in the comic.
- Innocently Insensitive: It seems that she deadnamed and misgendered Frisk due to not knowing Frisk's full story, just what she's been told by Susan.
- Jerk with a Heart of Gold: She's actually a fairly good person whose Fantastic Racism is motivated by fear and ignorance as opposed to genuine hatred.
- Professional Butt-Kisser: Towards customers. She goes from chewing out Jason to putting on a fake polite persona for Aidrian.
Noah EspinozaJanet's son; a boy attending Elkwood Elementary who comes along on the cultural appreciation field trip to Monsterland with students from Frisk's school.
- Berserk Button: Insulting Janet.
- Disappeared Dad: It's merely implied in the comic itself thus far, but his father isn't around.
- Mama Bear: An Inverted Trope, he gets set off easily when people speak poorly of his mother.
James LacasseJason's father, Miu's husband, and CEO of a cosmetics company, James is a big fan of Mettaton.
- Good Parents: Along with Miu, he's definitely turning out to be this way.
- In Touch with His Feminine Side: He runs a makeup company and one of his favourite television stars is Mettaton, who is literally the poster boy for this trope.
- Open-Minded Parent: Very accepting of monsterkind, he and Miu have become Aidrian's "second family" after she was kicked out of her own home.
Miu LacasseAn artist and the mother of Jason and his siblings. Miu is revealed to be the original creator of Alphys' favourite Manga, Mew Mew Kissy Cutie, when she was in college.
- Berserk Button: Bringing up the Mew Mew Kissy Cutie 2 movie which was created after she sold the rights to Mew Mew Kissy Cutie. Her anger is rooted in the massive Adaptation Decay the character went through once it was no longer under her control.
- Informed Attribute: Is apparently a bit of a health nut, but given how early her appearance is, we've yet to see it.
- Old Shame: Selling the Mew Mew franchise to people who had no respect for the canon and basically tore apart "her baby".
- Open-Minded Parent: Along with James, she's an open-minded parent to their kids and fully accepts the existence of Monsters.
Jason's older brother, a nurse at a local hospital. Michael is described as kind, gentle, and liking kids.
Amelia LacasseJason's sister. She builds Monster Trucks and is described as Aidrian's arch-nemesis.
- Friendly Enemy: Adrien describes her as "her nemesis", but their attitude towards each other so far has not been particularly unpleasant and they may consider one another a Worthy Opponent.
- Masculine Girl, Feminine Boy: Appears to be this to her brother, Michael, with him being a sensitive nurse and her a Monster truck builder who Aidrian considers a nemesis.
- Silk Hiding Steel: She's pretty, elegant, stylish, and wears a lot of pink. And builds monster trucks for a living.
AskersBeings from another world who once communicated with the cast through Frisk's blog, but soon gained the power to speak and act more directly through the void.
- Fourth-Wall Mail Slot: Anyone can become an asker, even you, yes you, the person reading this sentence. You just send in an ask via AskBlog on Tumblr and it may be heard by the characters. You can not only speak to the Characters, you can also check their stats, look at souls, detect magic, and spy on dreams. Neat stuff like that. Though not all of the "Magic Anon" asks are accepted.
- Aura Vision: Strong enough magic is a Splash of Color (before the comic turned full color) to them, and they can also ask to see all the souls in a certain area, which is how they confirmed that Flowey was getting some of his soul back.
- Batman Gambit: Several askers have proven themselves quite good at this.
- An asker managed to get other characters to comfort Sans simply by yelling out to Gaster, Hermann, Papyrus, and Toriel that Sans was crying. They were there in an instant, and Toriel had a slice of pie ready.
- Later on, one asker (known as ClimaxStriker) orchestrated a plan to have other askers tell Chara while they're possessing Drunk Chara that Flowey became the "Absolute God of Hyper-White-Chocolate." This plan ultimately succeeded in drawing out Asriel's soul, and came extremely close to fully restoring Asriel.
- Continuing the white chocolate theme, askers confirmed that Callallied was Chara by talking about white chocolate in front of them. Callallied immediately started ranting about how white chocolate wasn't chocolate, confirming their suspicions.
- Blue-and-Orange Morality: Chara accuses them of thinking of the persons of the blog as characters, not as people. While they're not entirely wrong, they're also not entirely right the askers are, for the most part, benevolent and try to help the characters out as much as they can.
- The Chessmaster: Successfully manipulated Aidrian and Jason into discovering Frisk was alive the whole time by getting them to watch their YouTube video of Sans fighting off Chara in his mind. Sure, Frisk wasn't in the video, but the account sure clued Aidrian and Jason in.
- Also, ClimaxStriker brought together a group of askers in an attempt to get Chara to give Asriel his soul back. It almost succeeds, too, only failing because Chara had been holding on to most of Asriel's soul for so long that they were determined to not give it up. The plan, for those who want to know, went like this: ClimaxStriker and his co-conspirators told Chara (at that point very drunk) that Flowey had become the "Absolute God of Hyper White Chocolate" and that he could only be stopped by hugging him. The contact drew out Asriel's soul, and would have returned it to Flowey had Asriel not been determined to try and help Chara.
- I Knew It!: Guessed several twists ahead of time, like the River Person being Hermann and Maverick being Asriel. The River Person has to cut out several spoilers from the asks, and Maverick does not do a very good job of denying their guesses.
- Word of God has said that one asker (whose ask they subsequently couldn't publish) managed to guess Chara's hidden plan.
- A few of them correctly concluded that Chara had the rest of Asriel's soul, and used this information to trick Chara into almost transferring it completely back to Flowey.
- Kick the Dog: Some askers are all too willing to use their words to torture the characters, sometimes at the worst times. Chara uses this as an example about how the world needs to die, despite there also being benevolent askers who hate it when hurtful asks get through.
- More Than Mind Control: It's theorized by Alphys that the askers are inadvertently making it so that anyone who hears them will answer their questions and not be too freaked out by hearing disembodied voices from across the void.
- Shipper on Deck: Most ship Soriel and Papyton.
- Spanner in the Works: Ruined Chara's plan to possess Frisk by warning Sans and the others about it.
- Token Evil Teammate: Most of the askers are benevolent towards Frisk and company, but every so often, there are ones who enjoyed the Genocide run or will lend Chara power.
- Too Dumb to Live: It may have been the truth, but telling a third degree blackbelt in karate that her dead sibling is Not Quite Dead to her face, after a whole entire year of her believing it and with no proof, was not the wisest of moves to make. The askers were just lucky she couldn't touch them.
- What the Hell, Hero?: The askers turned this back onto Hermann after she basically told Gaster everything he's been telling himself for years. One speech was actually given to the askers by Monster Kid after the askers started blaming Frisk for Sans getting stabbed by Chara moments after Frisk begged him to spare Chara. They were right about everyone being "a bunch of Smelly Turds" in that moment.
CharaThe first fallen human. They return to life with a plan to destroy the world out of hatred of the evil it contains.
- Alcohol-Induced Idiocy: Fell for the askers' story about Flowey having become the Absolute God of Hyper White Chocolate and needing to be defeated by hugs when they possessed Drunk Chara after Drunk Chara had ingested six bottles of wine.
- Ambiguous Gender: Is agender, like Frisk. Their biological sex has been revealed as female in the same update that's detailed in the Dark and Troubled Past entry.
- And Then What?: Gets asked this by Paolo, regarding their plan to convince Frisk to go genocide again. Chara is convinced that since Frisk is a good person, they'll accept that everything is evil. Paolo asks them what they'll do if Frisk refuses. They cannot answer, since their whole motivation is basically just an excuse to lash out at the world.
- Back from the Dead: They exploit the void-rift Sans created to return to the living world, albeit as a ghost-like entity.
- They come back in a more complete sense when they metamorphize into a skeleton monster.
- Being Evil Sucks: Their refusal to accept redemption means that they're pretty much trapped in a vicious cycle of self-loathing and lashing out, being offered friendship and rejecting it because of said self-loathing, causing them to lash out to get the painful situation to stop, and so forth. Askers have even pointed out that a counterpart of theirs who did have a HeelFace Turn (the Chara from Ask Drunk Chara) is in a much better place having accepted their loved ones than AFAC!Chara is pushing them away, but they get ignored.
- Berserk Button: Chara doesn't consider white chocolate to be chocolate, and is very annoyed when someone asks if it's their favorite kind. Askers have pressed it as a way to manipulate them. Twice.
- They also get really upset whenever someone brings up their past relationships to Asriel, Asgore, and Toriel.
- They also get really angry and defensive whenever someone acts in a way that challenges their 'everyone deserves to die' worldview, since it's basically a coping mechanism for their guilt.
- Black and White Insanity: Except they don't seem to believe that there is any white.
- Child Mage: During their time with the Dreemurrs, they were taught magic, and they're talented enough to perform somewhat complex magic. Becoming a ghost makes it even easier to use magic.
- Dark and Troubled Past: Implied when they first met Toriel, where their leg breaks when they try to look tough and they claimed to have gouged a man's eye out for a moldy slice of bread, something they immediately regret saying. This suggested a miserable life on the surface, to put it mildly.
- Oh yes they did. Their biological parents were very good people who lived on a tiny island village in the middle of the ocean. But their happy life was destroyed when pirates raided the village, kidnapped Chara as some kind of trophy, and killed their mother when she tried to save her child. Chara was driven to the point where they slit the crew's throats while they were all drunk. Can you really blame them for what they are now, when they had a past like this?
- Despair Event Horizon: While possessing Drunk Chara, they start to realize what they've become and question what the point of their actions is. This culminates in them seemingly vanishing and the Identity Amnesia discussed below.
- Driven to Suicide: A year after the pirate raid, they leapt into Mt Ebott because they wanted to die.
- Demonic Possession: As a determined human ghost, they've done this several times throughout the blog. Their victims in canonical order are Sans and Drunk Chara.
- Subverted and played with for Callallied. It at first appears Chara possessed them, but it later turns out Callallied was created by Chara and used as an alter ego.
- Even Evil Has Loved Ones: They deny it, but it's very clear that they deeply care for Asriel. A vision of Asriel apologizing to them and begging them not to destroy the world leaves them very shaken.
- They're also a lot nicer when dealing with Maverick (an older alternate Asriel) than they are with almost anyone else, lightly teasing him and only reacting negatively when informed that Maverick cared about his Chara even though his Chara killed people.
- Evil Cannot Comprehend Good: Downplayed, since the point is eventually driven home, but at first they're incapable of understanding Drunk Chara being The Atoner.
- Foil: To Frisk. They look alike, are both agender (and their biological sexes contrast), and are both The Determinator. However, Frisk acknowledges the bad in people and forgives them for it, while Chara never forgives anyone and so cannot see past the world's evil.
- Heel Realization: During their spirit's travels with Frisk as their Lemony Narrator, Chara began to consider the possibility that maybe the world wasn't messed up and instead they were the one who was messed up. Unfortunately, it didn't exactly take since it was too painful for them to confront the fact that their actions were entirely inexcusable. The reason they're so hellbent on convincing Frisk of all people of their viewpoint is because if they can convince them that it's true, then they can fully convince themselves that they're not the bad guy. When they confront an alternate self of theirs who did have a Heel Realization that took, it ends up driving them past the Despair Event Horizon.
- He Who Fights Monsters: An ask gets them to stop trying to attack ADC!Frisk by pointing out that they're on a ship with a sword just like the pirates who ruined their childhood prior to meeting the Dreemurrs.
- Also became a literal example when they became a monster by bonding to their skeleton permanently. This is technically after they fought monsters in the previous genocide run timeline.
- Hypocrite: They take askers' defining characters as good or evil as evidence that the askers don't view them as people. The whole reason they want to destroy the world is because they think that it is evil.
- An asker calls them out on their hypocrisy in calling Drunk Chara a hypocrite because he's trying to redeem himself, while they themselves are actively and consciously doing what they know to be wrong, despite claiming to be "properly disgusted by [the genocide run]". Chara has no response to this.
- Identity Amnesia: See Trauma-Induced Amnesia.
- Jerkass Has a Point: A Played for Laughs variant, they don't consider white chocolate to be real chocolate, which isn't inaccurate since most chocolate products are based on cocoa solids, whereas white chocolate is based on cocoa butter with sugar and milk added to the mix.
- Missing Steps Plan: When their mysterious plan was revealed, it turns out to be: Pose as a monster at Frisk's school, befriend Frisk, something something something, Frisk agrees to kill everyone. Erika even pointed out earlier that Chara didn't seem to have a plan, or at least not a good one, because their possession of Drunk Chara had to be spontaneous. Doing that wasn't the sort of thing people do when they have good plans that they actually expect to succeed.
- My God, What Have I Done?: Chara does, to some extent, regret their actions in the Genocide Run. The unfortunate thing is, actually accepting that they did something absolutely inexcusable would be too painful, so they stopped short of the HeelFace Turn step and ended up becoming an Omnicidal Maniac in a desperate attempt to convince themselves that killing everyone was in some way justified.
- Nice Job Fixing It, Villain!: Word of God. Chara's actions made Frisk regret letting Chara be in control in the first place, leading them to be the "determined little ball of sunshine" they are now.
- Noble Demon: They think the world is irredeemable, therefore it needs to be destroyed. They include themself in that.
- Not So Different: They think that they are this with Drunk Chara because they're both irredeemable murderers. An asker points out that in reality, they're Not So Different because they're both utilizing destructive coping mechanisms (Drunk Chara... drinks, and Ghost Chara convinced themselves that their actions were okay because everything else was worse, and thus in need of destruction) for dealing with the guilt of going through a genocide run.
- Older Than They Look: At the current time of the comic, their chronological age is 110 years old, but they still act and appear like a child.
- Omnicidal Maniac: Mostly because they want to convince themselves that their horrible actions were in some way justified, so they tell themselves that the world is just as horrible and needs to die, basically excusing their Kick the Dog actions by calling them Kick the Son of a Bitch instead.
- Other Me Annoys Me: They and Man Who Speaks In Hands!Chara meet and exchange plans, and immediately call each other out as being stupid. Chara later calls MWSIH!Chara "delusional", and said that what MWSIH!Chara said was "a bunch of nonsense that didn't mean anything". They also has a problem with Ask Drunk Chara's version of Chara, although that's more because the idea of a Chara who gave up being an Omnicidal Maniac and ended up on the side of good challenges their Black and White Insanity.
- Our Liches Are Different: Resurrected their own skeleton, turning it into Callallied. Word of God gives a Sure, Let's Go with That response when an asker describes this as "the text book definition of a lich."
- Psychological Projection: Projects their Black and White Insanity and issues with redemption onto Drunk Chara, since Drunk Chara is The Atoner, and while AFC!Chara would like to be The Atoner, the aforementioned Black and White Insanity is preventing it, and AFC!Chara is deeply in denial of this. It's easier for them to think that Drunk Chara is trying to run away from and deny their problems, instead of acknowledging that they're the one who's running away from their problems, while Drunk Chara is the one trying to confront said problems.
- Redemption Rejection: They're fixated on the belief that either they're right and the world is irredeemable... or they're wrong and they are the irredeemable one. Whenever someone (asker or in-comic) brings up the possibility that nothing is irredeemable and they can make a HeelFace Turn, they dismiss it, getting angry and defensive if the matter is pressed.
- Red Eyes, Take Warning: In their first appearance, Chara was grayscale with red eyes. In later appearances, they're drawn in red, so it still applies.
- Reformed, but Rejected: A downplayed example. At the end of the "The Most Fabulous Place On Earth"-arc they express genuine regret over all the horrible things they've done and while they're accepted into the family easily enough (in no small part thanks to Frisk and a newly revived Asriel vouching for them) several characters remain cautious of them, with Sans outright threatening to kill them if they try any funny business and Toriel retroactively doubting her decision to take them back so quickly after all the harm they had caused up until that point.
- The Determinator: They were determined to rid the world of evil. At first, they thought humanity was evil as a result of their Dark and Troubled Past, and then they thought Monsters were evil as a result of that first kill of the genocide run (after they already gained EXP from killing pirates and their LV dropped as they felt guilt), giving what they described as a rush of power and began killing as a result. Now, they seem determined to be a better person as a result of Frisk giving them a much-needed speech on how much they hated who they were and how much Chara helped them become the true pacifist they are now with their funny observations, words of encouragement, and reminders to stay determined and that it wasn't too late to become a better person.
- Trauma Conga Line: See Dark and Troubled Past above. It all went downhill from there until they met the Dreemurs... and we know what happened after that.
- Trauma-Induced Amnesia: After their Despair Event Horizon, they forget who they were, leading to them believing their Callalied persona is the real them. It's unclear whether the amnesia was done deliberately or not.
- Villainous Breakdown: Spends the second half of Eclipse Total! in one, caused by being forced to confront their toxic viewpoint by the askers and Drunk Chara themselves.
- Villains Out Shopping: Seeing as they're the one who knitted Asgore's Mr. Dad Guy sweater, it's apparent that they like knitting. At one point, the askers spy them knitting for seemingly no reason.
- Walking Spoiler: Qualifies as this after certain developments. Specifcally, anything relating to their skeleton form, both pre- and post-recovery from amnesia, is a huge spoiler.
Narrator/Perseverance/Paolo RuizNarrator to the story. They are sentient with their own thoughts and opinions. Really doesn't like Maverick, and takes as many chances as possible to describe him in an unflattering manner.
- Ambiguous Gender: The straightest example in the comic. Not even they are entirely sure what they identify as.
- Berserk Button: Don't interrupt or screw up their narrations, they take their work seriously.
- Canon Character All Along: Their identity turns out to be that of the Purple Soul.
- Exactly What It Says on the Tin: Well, they ARE the Narrator.
- Hidden Depths: A longer appearance in ¡Eclipse Total! has them question their existence and role aside from narrating, worried that they only exist to be the narrator.
- It is later revealed that they are one of the fallen humans, by the name of Paolo.
- Lemony Narrator: At times, especially towards Maverick.
Camera Person/Patience/ErikaThe individual that decides what the audience/askers get to see.
- Adaptational Badass: In the AFAC Hunger Games, she places third and manages to kill Sans and Flowey, two of the hardest bosses in the game.
- Canon Character All Along: They are one of the fallen humans (the cyan soul).
- Exactly What It Says on the Tin
- Seer: According to TQ, has scrying magic.
Ask Filter/Justice/BlakeThe person that filters out asks that shouldn't get sent through to the cast.
- Berserk Button: Gets ticked off immensely by being blamed for letting asks trying to get Chara to attack ADC!Frisk through. Afterwards, gets angry at the Messenger for letting misgendering askers through.
- Canon Character All Along: They are one of the fallen humans the yellow soul.
- Exactly What It Says on the Tin
- Hand Blast: They can fire magic beams with a Finger Gun.
- Talk to the Fist: A variant. After The Reveal that Blake filters the asks, a stupid ask pops up. Blake shoots it without hesitation.
- Selective Enforcement: Is willing to allow through at least one ask that would emotionally harm Asgore, despite their job being to destroy such asks and their efforts to do so for every other character. The Messenger calls them out on this.
Ask Messenger/Integrity/OscarThey send asks approved by the Ask Filter (or that slipped by them) through to the cast.
- The Gadfly: Likes sending asks that will annoy/provoke an amusing reaction from the cast.Danny (during a tug-o-war over an ask): Stop!! Don't bother them!! They're having a nice moment!Oscar: That's exactly why I want to bother them!
- Incoming Ham: "It was I! Oscar! Soul of Integrity!!" *guitar sting*
- It Amused Me: They will let through asks that they think will lead to entertaining reactions. One example cited in a Call-Back is when they allowed asks that misgendered Frisk to get through to Aidrian.
- Pragmatic Hero: Only lets through asks that they either find funny or believe would serve a good purpose in the end. They will allow asks that get Chara to stop their violent deeds and confront themself, but won't let through asks that demonize Asgore for no good reason.
- Shipper on Deck: Very enthusiastic to send certain messages regarding Asgore and Janet's relationship through, though it's clear that this is at least partially out of wanting to see their reactions.
- Well-Intentioned Extremist: They let through some rather...unsavory asks that didn't do any good for Chara's mentality. However, they say they did so to get Chara to confront their toxic mindset, and that seems to have worked.
- "After all...they put the knife down, didn't they."
Delivery Person/Kindness/DannyThey send items provided by askers through to the characters. At least they used to.
- Actual Pacifist: Implied. They apparently stopped sending items through after Aidrian recieved the "Frictionless Frying Pan of Unspeakable Mediocrity," commenting that "frying pans shouldn't be used to hurt people." This is especially notable due not only to their trait being Kindness, but also the fact that the "weapon" associated with them in the game was a frying pan, meaning they either never hurt anyone, or they did and are undergoing My God, What Have I Done?.
- Moment Killer: Defies the trope by stopping Oscar from sending Asgore and Janet shipping asks because "they're having a nice moment".
Ask Censor/Bravery/HanahThe person who censors foul language in the comic.
- Epic Fail: In the AFAC Hunger Games, they somehow manage to starve to death two days in (which is far sooner than people begin dying of hunger). The creator wonders if they fasted before the games.
- Gosh Dang It to Heck!: Their first line is this, combined with complaining about all the cursing in the comic.
- Hidden Depths: Understands Kayfabe and quickly realizes how the heroes can use it to minimize the damage from the Aidrian-Flowers fight.
- Incoming Ham: Their first line is yelling at askers for using too much swearing.
- What the Hell, Hero?: Calls out askers for their foul language. "MY EARS AREN'T TRASH CANS YA GOSH DIDDLY DARN HOOLIGANS!"
MWSIH!Gaster/"Goopster"An alternate version of Gaster, protagonist of Man Who Speaks In Hands. Ends up in Ask Frisk and Company after discovering a portal in his "grey room."
- Berserk Button: His first reaction to meeting Flowey is to attempt to blow him into oblivion for what he did during Undertale canon and a previous MWSIH arc.
- In-Series Nickname: Referred to as "Goopster," a reference to how he is seemingly made of goop (and is liable to literally melt).
Drunk Chara/"Bottles"An aged up version of Chara from Ask Drunk Chara, who happens to be alcoholic. They wind up in AFAC after falling down a manhole. This version is demi-male, meaning they accept gender-neutral or male pronouns.
- The Alcoholic: He's called drunk for a reason.
- The Atoner: A major difference between him and AFAC!Chara he recognizes his sins, regrets them, and has moved on.
- Demonic Possession: Gets possessed by AFAC!Chara.
- Distracted by the Sexy: Gets distracted by shirtless ADC!Frisk. It causes their mindscape to turn pink and sparkly, much to AFAC!Chara's annoyance.
- Good Counterpart: They're basically what AFAC!Chara might have been if their Heel Realization had fully sunken in. Askers even point out that for all their issues and regret over their past actions (the reason why they drink so heavily), they're a lot happier living with their friends and family than the Chara who is plotting to destroy the world.
- Hypocrite: AFAC!Chara calls him this because he's scared of AFAC!Chara and is The Atoner ("You apparently think you can make it all better by being sorry"), but it's pretty clearly because AFAC!Chara is projecting their own issues with the idea of redemption onto him, rather than Drunk Chara actually being hypocritical.
- Other Me Annoys Me: He's terrified of AFAC!Chara, because that Chara is a lot like him before he repented.
ADC!FriskAsk Drunk Chara's incarnation of Frisk, who is also aged up. They are currently dating Drunk Chara, but no one else knows yet (except ADC!Asriel). This Frisk is, like Drunk Chara, demi-male.
- All-Loving Hero: Tries to reach out to AFAC!Chara when it's clear that they are suffering an emotional breakdown.
- Big Damn Heroes: Their first appearance in the pages of AFAC is them showing up in Drunk Chara's mind to ward off AFAC!Chara.
- Mr. Fanservice: Their attire in Drunk Chara's mindscape includes a vest with no shirt. There's a reason everything in the mindscape goes bright and sparkly when Drunk Chara spots them.
