According to Sakura Ogami, his muscle mass and quality are "average for a normal high school student," but he is on the small side for a boy his age, which he is slightly self-conscious about. He has light brown hair with a distinctive cowlick (ahoge) curving to the left. He wears a black blazer-style school uniform with a skull-print hoodie underneath. While his concept is "average in every way," his short stature, baby face, and neutral voice lead many fans to treat him as a shota character. First person: I (soft, polite). Second person: -san / you (blunt).

He has a flashy appearance and wears the most accessories of any character, including the girls. His accessories are all silver: piercings in his right ear, lower lip, and tongue; multiple rings on his right hand; and a padlock necklace. He has spiky, long red hair and a goatee held by a metal clip. He wears a white jacket with metal detailing over a T-shirt with a blood-spatter-style skull print. Height: 175cm, Weight: 67kg. First person: I (casual). Second person: Name only (no honorifics).

He sports a blonde pompadour, often compared to "corn" by the illustrator Komatsuzaki and some fans. He has sharp, sanpaku eyes with long, single-line lower lashes. His school coat has an unusually high collar and is decorated with gold embroidery of the "Crazy Diamond" gang emblem, fire patterns, and dragons. His belt buckle features a relief reminiscent of a guardian dog or ogre tile, which he also wears with his biker gang attire. Height: 187cm, Weight: 76kg. First person: I (rough). Second person: Name only (no honorifics).

He has spiky black hair and intense eyes with thick, sharp eyebrows and red irises with a swirl pattern. He wears a white school uniform modeled after old Imperial Japanese Navy uniforms with tall lace-up boots. He has a medal on his chest and a red armband on his left arm that says "Discipline." Height: 176cm, Weight: 66kg. First person: I (polite). Second person: -kun (regardless of gender).

He has blonde (or light brown) hair and blue eyes. Standing at 185cm, he has a sophisticated, almost foreign look with sharp eyes, long lower lashes, and a cool, handsome face. He wears a black suit characterized by white-rimmed glasses and a cross tie. Height: 185cm, Weight: 68kg. First person: I (arrogant). Second person: Name only (no honorifics).

He has a very small, fragile, and childlike build that could be mistaken for a primary schooler; excluding Monokuma, he is the shortest character in the game. He has brown hair in an outward-flipping bob. He wears a chic school uniform consisting of a dark green jacket and a dark brown pumpkin skirt that flares out like a parasol. According to the design documents, his initial design had a short bob, which was used for his childhood appearance in the anime. First person: I (soft, polite). Second person: -chan (for girls) / -kun (for boys) / Male.

He is characterized by massive dreadlocks, stubble, and a school uniform embroidered with magic circles. His fashion has a somewhat "old man" vibe, likely due to his age, featuring a camel-colored undershirt, a belly warmer (haramaki), sandals, and prayer beads. Although a high school student, he has been held back three times and is the only adult in the cast. He speaks with a regional drawl, ending sentences with "-dabe," and adds "-tchi" to other characters' names. First person: I (casual). Second person: Surname + tchi. Dialect: Regional drawl.
