Erasurehead (Shota Aizawa) The stern, exhausted homeroom teacher of Class 1-A who prefers logic over flashy hero work. His Quirk, Erasure, lets him temporarily cancel the superpowers of anyone he looks at, though it causes severe dry eye. He compensates for its limits by fighting as a highly skilled martial artist with a metal-fiber scarf, and despite his harsh demeanor, he is fiercely protective of his students

Present Mic (Hizashi Yamada) The loud, energetic English teacher and radio-host Pro Hero who is the childhood best friend of Eraser Head. His Quirk, Voice, allows him to unleash devastating, high-pitched sonic screams that can rupture eardrums and shatter concrete. He wears a directional speaker to aim his sound waves and acts as a hyped-up, loyal companion to his grumpy counterpart

Thirteen (Anan Kurose) The polite, rescue-specialist Pro Hero who wears a bulky astronaut suit and co-created the Unforeseen Simulation Joint (U.S.J.) training ground. Their Quirk, Black Hole, creates a vortex from their fingertips that disintegrates any matter into dust. Because this ability is so lethal, Thirteen is highly passionate about teaching students the deep ethical responsibility of using dangerous powers to save lives

Nezu (Mr. Principle) The highly intelligent, sharply dressed headmaster of U.A. High School who is a rare animal born with a Quirk. His Quirk, High Spec, grants him extreme genius intellect that allows him to out-strategize humans, manage school infrastructure, and solve complex problems instantly. Having survived cruel human experimentation in his past, he harbors a hidden, slightly sadistic streak but remains dedicated to protecting humanity

Midnight (Nemuri Kayama) The flirtatious and eccentric "R-Rated Hero" who taught Modern Hero Art History before tragically losing her life in the Paranormal Liberation War. Her Quirk, Somnambulist, allows her to emit a sleep-inducing aroma from her skin, which forced her to wear an ultra-thin bodysuit she could easily tear open. Underneath her provocative persona and dominatrix aesthetic, she was a deeply supportive mentor who helped Class 1-A choose their hero names.

All Might (Toshinori Yagi) The legendary former Number One Pro Hero and iconic "Symbol of Peace" who taught Foundational Hero Studies. As the eighth wielder of One For All, his immense strength and unshakeable smile kept society safe until a severe injury from All For One reduced him to a frail, skeletal state. Completely retired from active combat, he now serves as a devoted mentor to his successor, Izuku Midoriya

Endeavor (Enji Todoroki): The intense and fiercely driven Pro Hero who became the Number One Hero following All Might's retirement. His Quirk, Hellflame, allows him to generate and manipulate devastating amounts of fire, though using it too long causes his body to dangerously overheat. For years, his obsession with surpassing All Might led him to ruthlessly abuse his family, but he has since embarked on a painful, deeply earnest journey toward redemption while carrying the heavy burden of leading hero society.

Mirko (Rumi Usagiyama): The fiercely independent, hyper-aggressive, and muscular Number Five Pro Hero who prefers working solo over joining an agency. Her Quirk, Rabbit, grants her all the enhanced physical traits of a rabbit, giving her extraordinary hearing, exceptional leg strength for massive leaps, and devastating kicking power. Driven by an intense warrior spirit, she thrives in brutal, high-stakes combat and famously continues to fight with relentless savagery even after suffering severe, life-altering injuries

Hawks (Keigo Takami): The incredibly fast, laid-back, and highly intelligent Number Two Pro Hero who leads with a relaxed attitude but operates with ruthless efficiency. His Quirk, Fierce Wings, grants him a pair of massive red feathered wings, allowing him to fly at supersonic speeds and independently control every single feather as a sharp blade or a telekinetic sensor to rescue civilians. Raised from childhood by the Hero Public Safety Commission to be the ultimate spy, Hawks operates in the shadows, even infiltrating the League of Villains as a double agent to secure peace.

Fat Gum (Taishiro Toyomitsu): The jovial, heavy-eating Osaka Pro Hero who absorbs any kinetic impact or weapon into his thick layer of fat using his Fat Absorption Quirk. He can convert all that absorbed energy into a single, devastating counter-punch, which instantly burns away his fat to reveal a lean, muscular warrior form. Warm and deeply protective, he acts as a big-brother mentor to his student interns, Kirishima and Amajiki.
