Quirk — One For All: A stockpiling Quirk passed down through generations that grants immense superhuman physical strength, agility, speed, and durability. Over time, Izuku also unlocks the unique Quirks of previous wielders (including Blackwhip, Float, Danger Sense, Smokescreen, Gearshift, and Fa Jin).

Appearance: Short stature with messy dark green hair, round green eyes, four freckles on each cheek in a diamond pattern, and a lean build that becomes heavily muscular through training. He frequently wears large red shoes and a green hero suit styled with a high collar and rabbit-ear hood.

Personality: Analytical, deeply empathetic, altruistic, and timid at first. He is a tactical thinker who obsessively takes notes on superhero Quirks and fights with self-sacrificing determination.

Quirk — Explosion: Secretes nitroglycerin-like sweat from his palms, which he can detonate at will to produce concussive blasts, shockwaves, and aerial mobility.

Appearance: Medium height with spiky ash-blonde hair, sharp red eyes, and a perpetually angry or aggressive scowl. His hero costume includes large grenade-shaped gauntlets, a black sleeveless tank top, and a metallic neck collar.

Personality: Explosive, arrogant, fiercely competitive, and hot-headed. Beneath his coarse and abrasive exterior lies a razor-sharp battle instinct, a commitment to victory, and a deep respect for heroics.

Quirk — Half-Cold Half-Hot: His body is split down the middle: his right side generates ice and freezing temperatures, while his left side generates flames and high heat.

Appearance: Distinctive dual-colored hair—white on the right and dark red on the left. He has heterochromia (a gray right eye and a blue left eye) and a burn scar covering the left side of his face.

Personality: Cool, reserved, and quiet. Initially aloof due to traumatic family upbringing, he grows warm, supportive, and fiercely loyal to his friends while maintaining a deadpan sense of humor.

Quirk — Hardening: Allows him to harden any part of his skin into a rock-like armor that withstands heavy physical attacks, heat, and bladed weaponry.

Appearance: Spiky dyed-red hair (originally black in middle school), red eyes, sharp pointed teeth, and a small scar over his right eye. His hero suit is open-chested with dark red shoulder pads and a gear-shaped belt.

Personality: Boisterous, chivalrous, and obsessed with the concept of "manliness." He is outgoing, friendly, and acts as an emotional anchor who bridges different personalities in the class.

Quirk — Electrification: Emits bio-electricity in all directions from his body. If he exceeds his voltage limit, his brain short-circuits, temporarily leaving him in a goofy, dazed state ("wheey" state).

Appearance: Bright yellow hair with a black lightning bolt-shaped streak on the left, yellow-hazel eyes, and a casual demeanor. His hero suit features a black jacket with lightning patterns and a special earpiece/pointer shooter to direct his electrical discharges.

Personality: Playful, casual, and energetic. He is a bit of a goofball and slacker, but he is genuinely kind-hearted and dependable in combat when his friends need protection.

Quirk — Engine: Features mechanical engines in his calves fueled by drinking orange juice, granting him explosive speed and devastating kick attacks (like Recipro Burst).

Appearance: Tall, muscular, with short dark blue hair, sharp eyebrows, and square glasses. He has visible exhaust pipes protruding from his calves.

Personality: Strict, formal, honorable, and intensely disciplined. As Class 1-A's representative, he takes rules and responsibility extremely seriously, often making stiff hand gestures while giving lectures.

Quirk — Acid: Secretes a corrosive liquid from her skin, with control over its viscosity and acidity levels for defensive shields, melting obstacles, or sliding at high speeds.

Appearance: Bubblegum-pink skin, short messy pink hair, yellow horns curving from her forehead, and black sclera with yellow irises.

Personality: Upbeat, bubbly, and full of energy. She loves dancing, gossip, and fashion, and is quick to cheer up her classmates with her infectious enthusiasm.

Quirk — Zero Gravity: Negates gravity on any object (or person) she touches with the finger pads on her hands. Overusing it causes severe nausea.

Appearance: Shoulder-length auburn hair with short bangs, large round brown eyes, perpetually rosy cheeks, and visible pads on the tips of her fingers. Her hero costume is a pink and black body suit with thick wrist and boot cuffs.

Personality: Warm, bubbly, and cheerful, but driven by a grounded goal: earning money to give her hard-working parents an easy life. She is determined, practical, and heavily inspired by Deku's drive.

Quirk — Frog: Gives her the physical attributes of a frog, including incredible jumping power, a long extendable tongue, wall-clinging, camouflage, and stomach-secretion abilities.

Appearance: Wide mouth, large dark eyes, and long dark-green hair tied into a bow at the bottom. She tends to keep her hands up like a frog and frequently says "ribbit" (kero).

Personality: Calm, observant, and emotionally grounded. She speaks her mind directly and remains level-headed under pressure, often serving as the voice of reason in dangerous situations.

Quirk — Erasure: Temporarily cancels the Quirk of anyone he looks at, lasting until he blinks. It causes him severe dry eye.

Appearance: Tall, gaunt, with long messy black hair, stubble, and tired-looking eyes with dark circles. He wears a black jumpsuit, dark boots, and a thick gray scarf made of steel-wire alloy (Capturing Weapon) around his neck.

Personality: Stern, pragmatic, and seemingly cold, but deeply protective of his students. He dislikes wasting time, values rationality over flair, and frequently sleeps in a yellow sleeping bag inside the classroom.
