- Sympathetic Murderer: Only killed Rico as part of his and her Heroic Sacrifice to throw a wrench in Cimber's plans.
Rufus Price, All-Star Latinist
A fluent speaker of the Latin language, as well as an expert on Classical Studies. Rufus is highly-intelligent, but boasts a rather sizable ego. Survives to the endgame.- Bilingual Bonus: Much of his dialogue is littered with Latin words and phrases.
- Break the Haughty: The events of the story serve as this for Rufus, although particularly chapters 5 and 6.
- Heroic BSoD: Rico's death induces one. He doesn't speak for a while, and when he eventually opens his mouth again, he can only speak in Latin.
- Gratuitous Latin: Often, but taken up to eleven in the first half of the chapter 6 trial, due to Rico's death.

- Nice Guy: His defining attribute. Monobear even lampshades this.

- Star-Crossed Lovers: With Jordan. Their relationship essentially ends when he's outed as Cody and Markus's killer.

Jordan Koulibagh, All-Star Golfer
Although she may be carrying a chip on her shoulder, Jordan tends to keep herself to herself among the group. Commits suicide in chapter 5, therefore taking the role of both culprit and victim.- Driven to Suicide: Possibly a subversion, but she was in the right headspace to kill herself at the time, and if it was an accident she didn't really try to survive.
- Star-Crossed Lovers: With Theo. It ends tragically for both of them.

Randolph Luther, All-Star Monk

- Exact Words: Sure, he's a monk, but he never said he was a Buddhist monk. Rather, he's a cultist.

Lily Smith, All-Star Kawaii
A girl with a near-boundless font of energy and cheer who knows all about what it means to live a "cute" lifestyle. Survives to the endgame.- Break the Cutie: Two of her closest friends, Elizabeth and Jenny, both resort to murder.
- Gratuitous Japanese: As is expected from her title.
- Verbal Tic: "Desu!"
Austin Fitzpatrick, All-Star Idle
A boy whose talent appears to be nothing more than excelling at doing absolutely nothing. Austin spends his days lazing around and never putting his all into anything his tries. Survives to the endgame.- Ambiguously Gay: His sexuality is left deliberately vague.
- Brilliant, but Lazy: When he puts his mind to it, he has quite a gift for speaking. It's his words that pull the other students out of their despair during the final trial.

- Sleepy Head: Usually asleep or getting that way, particularly when he's upset. Eventually realizes that this is a sign of depression.
Taylor Erzen, All-Star Lucky
Despite having only being invited into Success Summit by lottery, Taylor nevertheless projects an air of confidence and beauty. Survives to the endgame.- Alpha Bitch: Downplayed. She's not really mean so much as snarky and immature, believing that absolutely nothing bad can happen to her and if she keeps up the popular kid act, everything will turn out fine. Eventually admits she's so used to things working out for her she never really grew up.
- Brainless Beauty / Dumb Blonde
- Born Lucky: As befitting her title.
- Minor Injury Overreaction: Deconstructed; her reaction to Monobear forcing her to change outfits quickly turns from the merely embarrassed to actual Sanity Slippage, to the point where Lily starts following her around to protect her from herself.
- Stepford Smiler: There's hints from the beginning that she's not as cheerfully ditzy and carefree as she likes to believe she is.
The Mastermind, Cimber Tillius, former All-Star Logician
The person behind Monobear, who trapped the sixteen students in the Mall of Monomerica and forced them to take part in the Shopping Spree of Mutual Killing. A ruthless militant dictator who took control of the remnant of the United States after the Tragedy occurred.

- Jerkass: They don't even bother with Monokuma's normal Faux Affably Evil, they're an unending tide of insults and condescension.

Rina Lupa, All-Star Psychologist
A stern, no-nonsense sort of girl who nonetheless cares deeply for her sister.

Eric "Sparky" Armstrong, All-Star Engineer
An awkward, but endearingly so, boy with a babyface and a talent for all things electrical.Ed Bell, All-Star Clown

A loud-mouthed young girl whose talent allows her to see into the past, present and future.- Large Ham: Practically any time she speaks.
- No Indoor Voice
Hunter Zaroff, All-Star Hunter
A serious and intimidating young woman, skilled with all kinds of weaponry.Shu Nguyen, All-Star Lawyer
Immoral and affluent, Shu is the sort of lawyer people would describe as a complete slimeball. His nature as a Control Freak also put him at odds with his fellow students. One of the culprits of chapter 2, and the victim of chapter 3.- Amoral Attorney
- Jerkass: He exploits the power he holds over those weaker than him however he sees fit.
Rosa Bellamy, All-Star Maid
Along with her revealing outfit, Rosa's looks and personality do nothing to refute the seductive maid stereotype she so embodies. One of the culprits of chapter 2.- Good Bad Girl: Ultimate subverted.
- Ms. Fanservice: In-Universe.
Maxwell Carswell, All-Star Mathematician
A quiet, unassuming boy, who'd prefer to sit down alone with his headphones than attempt to make conversation with his peers.

They just discourage people from trying to talk to him.
Billy Cosdon, All-Star Nerd
As hyperactive and awkward as his title would suggest, Billy has one of the highest levels of energy out of the entire group. One of the victims of chapter 2.- Verbal Tic: "Kapow!"
Eugene Ford, All-Star Lucky
An energetic and confident boy who's proud of his status as his class's All-Star Lucky.- Totally Radical: In a similar way to Cody and Austin, from the previous installment.
Ruby Jain, All-Star Equestrian
Being both elegant and well-spoken, Ruby presents a confident persona. She enjoys horse-riding as much as her title implies.Claude Marley, All-Star Poet
A mellow, laid-back young man with a gift for verse and rhyme. Often accompanies his poetry with his ukelele.John Matthews, All-Star Cheerleader
In spite of his girlish costume, John is little more than a thug that won't hesitate to throw his considerable weight around if he must. The culprit of chapter 3.- Alas, Poor Villain: He accidentally murders his best friend. Or rather, his only friend, given how he treats his companions.
- The Dragon: To Shu.
- Jerkass
- Mr. Fanservice: Although most people drawn to his appearance are repulsed by his personality.
- Real Men Wear Pink: His everyday outfit is nothing more than a pink skirt and matching top.
