Here's a list of Atlas Ablaze characters, along with some details about them. Some of them have canonical full names, where as others don't. Keep in mind that some of these details didn't make it into the game.

ALEXANDRIA LEWISIA KELLY

(ANDI/ALLY)

The main character of Atlas Ablaze. Andi is a 16 year old lesbian, (17 when the game ends) with very little self respect and a short temper due to them being frequently overstimulated. Andi is gullible, anxious and easily frustrated, but has a very big heart, despite being a tad bit judgmental. They're a little socially stunted, since they've spent a large part of their life with little to no real friends. Any epilogue comics set further in the future show Andi using they/them pronouns, though they use she/her prior to this. Andi's unwillingness to accept themself as nonbinary is hinted through Gabriella's identity.  (See below... somewhere down there. Look for the only one with purple skin.) Andi has ADHD and ARFID, but could possibly be read as autistic as well.

IRIS NADINE HUTSON

(NERIUM/NERI)

Love interest in Atlas Ablaze. Iris is a bisexual (possibly actually a lesbian without realizing it) s*x worker and is also Andi's girlfriend. The two of them meet at a gas station, then again at a party. Iris is sneaky and sometimes untrustworthy. She also has trouble trusting others, both due to her own capability to hide things as well as the way she's been treated in the past. She finds comfort in the way Andi treats her, very quickly becoming emotionally attached to them. Despite my first descriptions of her, she's not a bad person at all. She's very gentle the majority of the time and loves to make people happy. She enjoys long walks in the park, dry humor, and crying. She shows signs of borderline personality disorder, which would make sense due to her situation and the things she's struggled with throughout her life, though it's never addressed in the game.

NANCY ROSE COLEMAN

Andi's best friend. Nancy is 15 years old. Despite her appearance, she is painfully heterosexual. She's incredibly intelligent, focusing on her academics in order to have a stable and fulfilling life. Also to impress everyone around her. Also because if she isn't seen as smart, she'll feel worthless. Nancy bounces back and forth between having a very high and very low self esteem. She comes off as arrogant to some of the people around her, but Andi sees her as "the mom friend," and generally looks at her in a very positive light. Because of how different she and Andi are, the two of them are BOTH jealous of each other for different reasons. Nancy is in a long distance relationship with some guy named Paul. She was also once referred to as the funniest person in their friend group by one of the beta testers. That made me feel like a proud mom, or something.

BRADLY DANIEL MEIER

(BRAD)

Brad is a 15 year old (I think) absolute moron. He's one of the token straight friends. He's childish and self centered, always fighting to feel loved by the people around him. He tries really hard to fit in by doing things that he thinks will make people like him, like throwing parties or making crude jokes that are just ALMOST funny. He's a little bit like an alien pretending to be human, because he has literally no idea what he's doing and just wants to feel normal. Although he's easy to pity, he can be difficult to actually like. He has a really obvious, annoying crush on Nancy, and is shown to care deeply about Andi as well. Also his hair smells like soup.

LAKITA IMANI KABILA

(KITA)

Kita is a 17 year old bisexual with a very gloomy demeanor due to being generally very emo. She masks all of her anxiety and sadness with anger in order to feel a little more comfortable with how terrible she feels. Like Nancy, Kita is nurturing at heart but not everyone realizes it, due to her attitude. She frequently makes comments on Andi's poor eating habits, which comes from a good place but always makes Andi upset. She's aware that she isn't well liked, and doesn't want to try to make anyone like her. Kita values honesty above everything else. She cares VERY deeply for the people around her, but has a painfully avoidant attachment style. This is for good reason though, as she has a whole backstory that would count as a spoiler if I wrote it out here. It can be found in the "written extras" that go along with the pink ending. She spends a lot of time with Grace, even though the two of them are in some ways, total opposites.

DARPANA GRACE YADAV

(GRACE)

Can be misread as a villain in Atlas Ablaze. Grace is 15 years old, having been described at Kita's total opposite. While Kita is very direct and honest, Grace puts on a very bubbly, friendly mask until she suddenly snaps because something didn't go her way. She probably hid her true self better at some point, but in the timeline of Atlas Ablaze, everyone knows how Grace really is, causing her to be outcasted at school. David is the only person in their friend group who seems to love her unconditionally, being aware of certain aspects of her personality that no one else really understands in full. She is aromantic, and generally pretty detached. She thrives when she feels a sense of stability without boredom, but when she either gets bored or things feel unstable, she spirals.

DAVID ETHAN PARKER

(DAVE)

Can possibly become one of Andi's closest friends. David is 17 years old and asexual. If Andi doesn't befriend him, he may come off as very one dimensional. He's pretty much your stereotypical p*thead, though he has deeper reasons as to why he spends so much of his time high. David can provide extra side stories if befriended, which changes various aspects of certain routes. He canonically smells really bad.

DEVON JAKOB RUIZ HARRISON

Devon is 15 years old through most of the game, but 14 in the very beginning. He's a little airheaded and generally tries to focus on being positive, but blocks out important details of his life in order to do so. He's apathetic about that though, only caring about being happy. He's best friends with Richie.

RICHARD ANTON CEL TRADAT

(RICHIE/DICK)

Only his parents call him Dick, actually. Andi once called him P*enis Face because of this, but that felt too mean to include with his nicknames, as Richie is an absolute angel who deserves no disrespect. Richie is 14 years old through most of the game, but is 13 in the very beginning. He sketches out Andi the moment that they meet, due to him being somehow tied to a local p*mp who he's said to be loosely related to. Richie is sort of feminine yet thinks no one realizes he's gay. He's a very gentle person, making it easy for other's to walk all over him. He's most definitely a people pleaser. He's the youngest of the friend group. Brad finds him annoying, and in contrast to that, Kita  seems to take him under her wing at some point.

SAMANTHA DELIA LEÒN MARTIN

(SAM)

Sam is a 17 year old lesbian. Don't let her big, sad puppy eyes deceive you, she's generally pretty upbeat, despite her own struggles in life. Sam likes feeling strong and dependable, though she secretly searches for people she can emotionally depend on as well. She feels embarrassed when anyone sees her being too emotional. She and Brad become close friends. Although she wants people to know that she's tough and will absolutely kick their *sses if they mess with anyone she cares for, she also wants to seem approachable to some degree. Though it's not depicted in the game, canonically, Sam works out and is visibly muscular. She wears clothes that hide the shape of her body on purpose. As an adult, she puts on weight and looses some of her muscle as she learns to let her guard down more.

GABRIELLA

(GABBY)

Andi's imaginary friend/enemy. Gabriella does not exist, not only because they're a video game character, but because Andi made them up. They are essentially a personification of all of Andi's anxieties and insecurities. They enjoy pestering and belittling Andi, yet seem to still have a soft spot for them. They see themself as Andi's protector, or maybe more of a babysitter. The base of Gabriella's sprite was originally the same as Nancy's, though I altered both of their faces to make Gabby appear older and Nancy appear younger. Andi introduces Gabriella as Gabriel the messenger angel's twin from  H*ll.

As the list goes on from here, the characters become less and less relevant.

PATRICIA KELLY

(PATTY)

Andi's mom and Larry's wife. She has no canonical age. Patty is very nurturing and always has advice for Andi. For a while, she was their only friend. She's incredibly close with Andi, and depends on them emotionally. Though she shows a deep amount of love for those around her and is a good person, she makes some questionable choices as a mother. While taking Iris under her wing, she allowed her own child to become VERY close with a s*x worker who she didn't know all that well. She converted to Christianity while getting to know Larry.

LARRY KELLY

Andi's dad, probably rated 2/10 on Yelp. He has no canonical age. Larry is the root of the Christian beliefs in the Kelly household, though his wife and child's beliefs changed from his overtime. They are still Christians as well. Andi and their friends really enjoy Larry's sense of humor, even though they find him cringey. Although he can be hot headed, he's also very playful. He can also be very manipulative at times. Larry doesn't want Iris to hang out with Andi.

NESSA PERRY (left)

KAILYN SULLIVAN (right)

S*x workers/Iris's roommates. Nessa has no canonical age, but Kailyn is 28. Kailyn's humor is more whitey, whereas Nessa's is much dryer. They both seem to have an older sister type dynamic with Iris. Nessa knows Marcus the best out of the three of them.

AMARA MARTIN MORENO

Sam's mom, and coincidentally, Andi's doctor. If I say anything else about Amara, it would be considered a spoiler.

MARCUS

I forgot his canonical full name. It's irrelevant. He's ugly and terrible.

Iris, Nessa and Kailyn's p*mp. More people work under him than just them, but they're his favorites. They cost a lot more and are held to a higher standard with things like health and cleanliness. In turn, they receive a lot more security from him than anyone else would. He has a friendly relationship with the three of them, though he starts arguments about as often as he does, "nice," things for them. Marcus is implied to really like joking around, which might just be his only good quality. Except it's not really, because he seems annoying.

ADAM

Iris's client and friend. He sees a very different side to her than Andi and their friends would. Iris describes herself as if she has a different persona for different people, and it's clear she isn't fully honest with Adam. At the same time, she seems to be able to let her guard down more around him than she can with most people. Not much is known about his personality. 

PAUL PETTERSON

Nancy's boyfriend. He buys her flowers. He also looks kinda stupid.

TANYA

A kid Andi and Iris meet in a church. She shares the same base as Nessa for her face, which was meant to symbolize how even s*x workers are someone's kids, but it's not very obvious since they still look so different.

SOME GIRL AT A PARTY

Implied to be a college student. Andi thinks she's cute.

SOME GUY AT A PARTY

Also implied to be a college student. Ugliest character sprite I've ever made, like it's hilariously bad. He only has this once facial expression. One of the beta testers said, "EW," as soon as she saw him. Andi seems confused as to why his name isn't Josh, insisting to the player that he looks like a Josh.

GIRL IN THE UR IN! COMMERCIAL

Probably the equivalent to a sh*tty YouTuber/micro celebrity. Appeared in a commercial that plays too much. Everyone hates it.

ALIEN IN THE UR IN! COMMERCIAL

His low quality wig and clothes could NEVER help him fit in with humanity. What a waste of space.

PURPLEPIRATE667

Absolutely the equivalent of a sh*tty YouTuber/micro celebrity. If I cared enough, I'd list everyone in his comments as characters in this game too, but calling PurplePirate a character is a reach as it is, though Andi makes reference to him in conversation once. He's probably a racist.
