Izuku is the core protagonist of My Hero Academia. Born "Quirkless" in a world where nearly everyone has superpowers, he retained an unwavering, borderline obsessive desire to save others. His analytical mind is reflected in his habit of frantically muttering while scribbling detailed hero analyses in his notebooks.

After a chance encounter with the legendary hero All Might, Izuku inherits the legendary stockpile Quirk, One For All. This power grants him immense physical strength, speed, and durability, though his body initially breaks under the strain of its output. To cope, he develops "Full Cowling" to distribute the energy evenly. As the story progresses, he unlocks the Quirks of the previous One For All vestige holders:

Gearshift: Alters the speed of targets he touches.

Fa Jin: Stores and releases kinetic energy.

Danger Sense: Warns him of nearby threats.

Smokescreen: Generates thick clouds of smoke for cover.

Float: Allows him to suspend himself in mid-air.

Blackwhip: Produces tendrils of dark energy for grappling and restraint.

Physically, Izuku has messy, dark-green hair, freckles, and a initially slight build that he develops into a muscular physique through grueling training. His hero costume is a green jumpsuit featuring a cowl with rabbit-ear-like protrusions (mimicking All Might's signature hair) and a metal respirator mask.

Bakugo is Izuku’s childhood friend turned fierce rival. Defined by an explosive temper, massive pride, and a raw, instinctual genius for combat, he views victory as the ultimate expression of a hero. While initially arrogant and antagonistic, Bakugo undergoes profound character growth, evolving from a bully into a deeply loyal teammate who carries the heavy burden of his own expectations.

His Quirk, Explosion, allows him to secrete nitroglycerin-like sweat from his palms and ignite it at will. This lets him unleash devastating blasts, create shockwaves, and propel himself through the air with incredible speed and maneuverability.

Bakugo has spiky ash-blonde hair, sharp red eyes, and a perpetually intense scowl. His hero costume is highly aggressive, featuring massive grenade-shaped gauntlets on his forearms that store his sweat to release massive, concentrated explosions, along with a black sleeveless tank top, metallic neck brace, and a black-and-orange knee-burst design.

Shoto is the son of the Flame Hero, Endeavor. He entered U.A. High School through official recommendations, carrying a quiet, stoic demeanor and a heavy emotional trauma stemming from his father's abusive, perfectionist training. For a long time, Shoto refused to use the fire powers inherited from his father, relying solely on his mother's ice powers as a rejection of Endeavor's legacy. He eventually embraces his full potential after Izuku helps him realize the power belongs to him, not his father.

His Quirk, Half-Cold Half-Hot, splits his body down the middle:

Right Side: Generates freezing ice and frost.

Left Side: Unleashes scorching fire and heat.

This split is physically striking: his hair is perfectly divided into white on the right and red on the left, and his eyes are heterochromatic (grey on the right, blue on the left). He also bears a distinct burn scar over his left eye, a mark from a childhood trauma involving his mother. His hero costume has evolved from a simple white suit that covered his fire side to a practical, dark-blue tactical jumpsuit equipped with temperature-regulating gear.

Kirishima is the energetic, warm-hearted "heart" of Class 1-A. Obsessed with the concept of "manliness"—which to him means chivalry, courage, and protecting others—he is one of the few classmates who successfully befriends the abrasive Bakugo. Despite his boisterous personality, Kirishima secretly struggled with deep self-doubt regarding the perceived plainness of his Quirk compared to his classmates.

His Quirk, Hardening, allows him to stiffen any part of his body to a rock-solid, blade-like density. This makes him an exceptional close-range brawler and human shield. His ultimate technique, Red Riot Unbreakable, pushes his hardening to its absolute limit for a short duration, making him completely impervious to most physical attacks and giving him a monstrous, jagged appearance.

Kirishima has bright, dyed-red hair styled into spiky tufts, sharp teeth, and a small scar over his right eye. His hero costume is designed for close-combat mobility, consisting of a dark, bare-chested design with gear-shaped shoulder guards, a tattered red sash around his waist, and protective headgear that frames his face.

Kaminari is the friendly, social, and somewhat goofy casual guy of Class 1-A. While not academically gifted, he is incredibly supportive of his peers and acts as a major source of comic relief, frequently flirting or teasing his classmates.

His Quirk, Electrification, allows him to absorb and emit electricity from his body. While highly powerful, he initially struggled with aim, discharging his power in wide, uncontrolled bursts. If he exceeds his wattage limit by releasing too much electricity at once, his brain short-circuits, leaving him in a temporary, dazed state of complete silliness for about an hour. He eventually utilizes pointer-and-shooter support gear to aim his electrical currents precisely.

Denki has messy yellow hair with a black lightning-bolt streak on the left side and golden eyes. His hero costume is a casual, streetwear-inspired outfit featuring a black jacket with white lightning patterns, a white shirt, black pants, and a headpiece equipped with an eyepiece for aiming his electrical attacks.

Iida is the class representative of Class 1-A. He is highly disciplined, intensely serious, and governed by a strict moral code, often seen executing rigid, robotic hand gestures while urging his classmates to behave. He comes from the prestigious Ida family, a dynasty of beloved running heroes, and inherits the moniker Ingenium from his older brother, Tensei, after Tensei is forced into retirement by the Hero Killer, Stain.

His Quirk, Engine, manifests as physical engines protruding from his calves. Fuelled by orange juice, these engines grant him extraordinary running speed and kick-based kicking power. He can shift gears to adjust his speed and utilize Recipro Burst for a massive, high-speed dash that temporarily stalls his engines afterward.

Iida is tall, muscular, wears rectangular glasses, and has neatly parted dark-blue hair. His hero costume is a high-tech, aerodynamic suit of white-and-silver armor that closely resembles a sleek robotic exoskeleton, designed to minimize wind resistance and protect his legs.

Mina is an upbeat, highly athletic, and highly social girl who loves dancing and hanging out with her friends. She possesses an infectious energy and is often the driving force behind class social gatherings. Despite her bubbly nature, she is incredibly brave, having stood up to giant villains even before entering U.A.

His Quirk, Acid, allows her to secrete a corrosive liquid from her skin. She can control both the solubility and viscosity of this acid, utilizing it offensively to melt barriers, defensively to dissolve incoming projectiles, or practically to create a slick film under her feet to slide across the ground at high speeds.

Mina has a distinct alien-like appearance, featuring light pink skin, messy pink hair, two yellow horns protruding from her head, and eyes with black sclera and yellow irises. His hero costume is a flashy, colorful teal and purple camo-patterned skin-tight bodysuit paired with a cropped, fur-rimmed vest and protective acid-resistant boots.

Ochaco is a warm, bubbly, and fiercely empathetic girl who originally pursued hero work to earn money and give her parents a comfortable life. Over time, her motivations deepen as she witnesses the heavy burdens carried by heroes like Izuku, shifting her focus to "saving the heroes who save everyone."

Her Quirk, Zero Gravity, allows her to nullify the gravitational pull on any object she touches with all five pads of her fingertips. This lets her make heavy debris float, which she can then release to drop on opponents. Overusing her Quirk past her weight limit causes severe nausea and motion sickness. To offset this and handle close-combat situations, she trains extensively in martial arts under the pro hero Gunhead.

Ochaco has shoulder-length brown hair with a short fringe, large brown eyes, and permanent pink blush marks on her cheeks. Her fingertips feature distinct, pink pads resembling those of a cat. Her hero costume is a sleek pink-and-black bodysuit equipped with oversized wrist guards and boots designed to cushion her landings and mitigate gravity-related strain.

Tsuyu is an exceptionally level-headed, observant, and brutally honest girl who prefers to be called "Tsu" by her friends. She is a pillar of emotional stability for Class 1-A, often keeping her cool in high-stress situations where others panic.

Her Quirk, Frog, grants her the physiological traits of a frog. This includes:

Mobility: Incredible jumping power and the ability to cling to walls.

Tongue: An incredibly strong, prehensile tongue that can extend up to 20 meters.

Camouflage: The ability to blend into her surroundings.

Stomach: The capacity to swell her stomach to secrete a mild, paralyzing venom or store objects.

Tsuyu has a frog-like appearance with a wide mouth, large eyes, and long, dark-green hair tied in a bow-like knot at the bottom. Her hero costume is a green-and-black skin-tight suit with large, goggle-like headgear and yellow-and-green gloves that mimic webbed frog hands.

Wouldn't let me add more on details page, But Aizawa is the teacher with a quirk that allows him to disable other quirks :p
