Kyoka Jiro (The Cool Realist) • Personality: Pragmatic, sarcastic, and highly defensive, Jiro often puts up a punk-rock exterior to hide her deep-seated insecurities. Despite her sharp tongue—which she frequently uses to tease her goofier classmates—she is incredibly empathetic, organized, and fiercely protective of her friends. • Quirk: Earphone Jack (can plug her flexible, headphone-jack earlobes into any surface to amplify her heartbeat into devastating soundwaves, or use them to scout and detect incredibly faint noises).

Hanta Sero (The Laid-Back Anchor) • Personality: Relaxed, friendly, and highly sarcastic. Sero often acts as the "straight man" to the squad's more extreme antics, grounding their high-energy chaos with a chill, witty attitude. • Quirk: Tape (shoots highly durable adhesive tape from his elbows to swing from walls or trap enemies).

Katsuki Bakugo (The Reluctant Leader) • Personality: Crude, arrogant, short-tempered, and highly aggressive, Bakugo starts the school year pushing everyone away. However, he gradually tolerates—and subtly cares for—the group, even if he denies the squad's existence. • Quirk: Explosion (secretes nitroglycerin-like sweat to create massive blasts).

Mina Ashido (The Hype Woman) • Personality: Cheerful, easygoing, and incredibly expressive. Mina is the primary female presence in the group and shares a middle school history with Kirishima, giving them a deep underlying bond of mutual respect. • Quirk: Acid (allows her to secrete a corrosive liquid from her body, the solubility of which she can control).

Denki Kaminari (The High-Energy Socialite) • Personality: Friendly, highly social, energetic, and a bit of a goofball. On Tumblr, many fans share the headcanon that the group functions more like "The Kamisquad" because Kaminari's easygoing nature makes him a natural hub for bringing the others together. • Quirk: Electrification (can discharge massive amounts of electricity, though overusing it short-circuits his brain into a temporary dazed state).

Eijiro Kirishima (The Bridge / Right-Hand Man) • Personality: Outgoing, friendly, and obsessed with things being "manly" and honorable. Kirishima is the only person who can consistently match Bakugo's intensity and break through his defensive walls, effectively acting as the glue that binds the squad together. • Quirk: Hardening (can stiffen any part of his body to become diamond-hard).
