Hero Name: Lemillion. Quirk: Permeation (allows him to pass through any physical matter). Characteristics: The central figure of the Big 3. With a bright and positive personality, he is a top-tier student described by Mr. Aizawa as "the man closest to being the No. 1 hero." Hair style: Retro, classic American comic-style blonde hair. He wears it in a style similar to a pompadour or regency, with the bangs swept up and the rest slicked back. Design origin: To match his facial features, which pay homage to classic American comic book heroes, his hair is designed in a simple yet powerful cartoonish style.

Hero Name: Nejire-chan. Quirk: Wave Motion (converts her vitality into shockwaves. They travel in a spiral, making them slow but high-powered). Characteristics: The only female member of the Big 3. She is a free-spirited girl with intense curiosity who will ask about anything she finds strange. Hair style: Extremely long, pale blue hair that reaches down to her feet. Her bangs are parted in the center, and the most distinctive feature is the large spiral curls on both sides of her face, reminiscent of her "Wave Motion" quirk. Design origin: An iconic design that directly incorporates her quirk and her name, "Nejire" (meaning twist/spiral), into her hairstyle.

Hero Name: Suneater. Quirk: Manifest (can manifest the characteristics of things he has eaten into his body, using things like octopus or clams as weapons). Characteristics: Mirio's childhood friend. While his skills are pro-level, he is mentally very fragile and has the heart of a flea. Hair style: Messy, unkempt dark blue hair that is long enough to cover half his face and eyes. Design origin: His introverted and negative personality, and his desire to "become a wall" due to fear of others' gazes, are directly reflected in his bangs and side hair that shroud his face.
