Izuku Midoriya, also known by his hero alias Deku, is a young man with messy, dark-green hair, large expressive green eyes, and light freckles shaped like diamonds on his cheeks. Originally born completely Quirkless, he inherits One For All from All Might, a massive power-stockpiling Quirk that also grants him access to the distinct abilities of all its previous users—including Blackwhip, Float, Danger Sense, Smokescreen, Fa Jin, and Gearshift. Initially timid, insecure, and prone to tearing up under pressure due to years of bullying, Izuku grows into a fiercely determined, deeply altruistic, and analytically brilliant hero who habitually mutters his thought process out loud and will recklessly put himself in harm's way to save anyone in need.

Katsuki Bakugo is a fiery student from the anime My Hero Academia who features spiky ash-blonde hair, sharp crimson eyes, and an athletic build. His Quirk, Explosion, allows him to secrete nitroglycerin-like sweat from his palms and ignite it at will to launch devastating blasts, propel himself through the air, and fight with high-mobility martial arts. Personality-wise, he is loud, aggressive, arrogant, and fiercely competitive with a massive ego, yet he possesses a brilliant combat intellect, a perfectionist's drive, and an unyielding commitment to becoming the number one hero.

Shoto Todoroki is a tall, muscular teenager from My Hero Academia who features distinct split-colored hair—white on the right side and crimson-red on the left—heterochromatic eyes (turquoise on the left and dark gray on the right), and a prominent burn scar over his left eye. His Emitter-type Quirk, Half-Cold Half-Hot, lets him generate massive waves of ice from his right side and intense flames from his left side, though he must balance their usage to avoid frostbite or overheating. Initially stoic, cold, and intensely resentful of his abusive father, the Pro Hero Endeavor, Shoto gradually thaws out, becoming a calm, cooperative, and deeply loyal hero-in-training after learning to embrace his fire abilities.

Ochaco Uraraka is a bright and bubbly student in Class 1-A at U.A. High School, easily recognized by her round face, shoulder-length brown bob with short bangs, and distinctively large, warm brown eyes. Her Quirk, Zero Gravity, allows her to make any object or person she touches weightless by manipulating the gravitational forces acting upon them, though overusing this ability causes her severe nausea. Personality-wise, Ochaco is fiercely empathetic, cheerful, and fiercely determined; while she initially pursues a career as a Pro Hero to financially support her parents, her core motivation evolves into a deep-seated desire to protect and save heroes when they themselves are hurting.

Shota Aizawa, also known by his hero name Eraser Head, is a tall, slender man with pale skin, messy shoulder-length black hair that partially frames his face, and tired, half-lidded black eyes that often appear bloodshot. He is typically seen wearing a dark, baggy outfit paired with a distinctive, scarf-like capture weapon wrapped around his neck and yellow goggles that hide his gaze. His Quirk is "Erasure," which allows him to temporarily nullify the superhuman abilities of anyone he looks at, though it deactivates if he blinks or looks away and gives him severe dry eye. Behind his cold, strict, and seemingly exhausted demeanor lies a deeply caring teacher and pro hero who values practicality, dislikes wasted time, and holds high expectations for his students to ensure they survive the harsh realities of hero society.

Tenya Iida is a prominent character in My Hero Academia, easily recognized by his tall, muscular build, short dark-blue hair, square-framed glasses, and notably thick calves that house his unique anatomy. As the representative of Class 1-A, his personality is defined by an intense sense of duty, organization, and a rigid, hyper-serious adherence to discipline, though his earnest desire to lead often manifests as comical, robotic hand gestures. His Quirk, Engine, manifests as jet-like engines protruding from his calves, giving him extraordinary running speed and kick-based combat power by fueling them with his own stamina and orange juice. While initially appearing overly strict, Iida is a deeply loyal, empathetic, and protective friend who constantly strives to honor his family’s heroic legacy as the current bearer of the name Ingenium.

Mina Ashido from My Hero Academia is a cheerful and highly athletic student at U.A. High School with a distinct, alien-like appearance. Her striking physical features include bright pink skin, unruly pink hair, and two yellow horns protruding from her head, along with black sclera and yellow irises. Her Quirk, Acid, allows her to secrete a corrosive liquid from her body, controlling both its solubility and viscosity so she can dissolve targets or safely slide along the ground. Mina possesses an incredibly bubbly, upbeat, and empathetic personality, always bringing high energy to Class 1-A and showing a strong desire to hanging out with her friends and socialize, though she can occasionally be a bit airheaded when it comes to schoolwork.
