Shota Aizawa and Hizashi Yamada

Hizashi Yamada, best known as the Pro Hero Present Mic, is defined by an energetic, boisterous, and intensely charismatic personality. He operates with the high-octane enthusiasm of a radio DJ and stadium announcer, rarely speaking at a normal volume and constantly using English interjections, dramatic hand gestures, and theatrical hype-man poses. Whether he is hosting a radio show, commentating on the U.A. Sports Festival, or teaching an English class, Hizashi brings an infectious optimism that instantly elevates the energy of any room he enters.

Beneath his loud, rockstar persona lies a deeply intelligent, observant, and empathetic individual. As a veteran underground-adjacent hero and U.A. educator, Hizashi is far sharper than his flashy exterior suggests. He possesses great situational awareness in combat, quickly analyzing enemy tactics and acting as a rational voice of reason during crisis meetings. He was notably the first teacher to suspect the presence of a traitor within U.A. High, demonstrating a sharp intuition that contrasts with his seemingly carefree demeanor.

Hizashi’s core emotional driver is his fierce loyalty and profound empathy for those he cares about. He acts as the bright, cheerful counterweight to his long-time friend Shota Aizawa's gloomy, stoic nature, constantly pushing Aizawa to engage with others while quietly looking out for his well-being. Having endured severe grief and trauma in his youth following the death of his close friend Oboro Shirakumo, Hizashi uses his loud, positive attitude partly as a deliberate choice to uplift those around him and fight off the darkness of their shared past.

Despite his loud voice and booming power, Hizashi displays a genuine care for his students' safety and emotional states. He balances his roles as an entertainer, teacher, and hero effortlessly, maintaining a warm, approachable attitude toward civilians and students alike while remaining a dependable, highly capable protector when lives are on th

Hizashi Yamada’s Quirk is Voice, an incredibly powerful emitter-type ability that grants him superhuman control over the volume and pitch of his vocal cords. By simply shouting or screaming, Hizashi can generate deafening, high-frequency sound waves that reach devastating decibel levels. His Quirk is so naturally potent that it manifested the exact moment he was born—his very first newborn cry was loud enough to cause his parents' and the delivering doctor's ears to bleed.

In combat, Present Mic acts as a devastating long-range suppression specialist. His sonic screams travel at the speed of sound, making them virtually impossible for opponents to dodge or outrun. The intense noise can instantly disorient enemies, shatter eardrums, disrupt enemy coordination, and cause agonizing physical pain. At maximum output, the sheer kinetic force behind his vocal projections is strong enough to shatter glass, tear through solid concrete, and physically blow away large groups of enemies or heavy debris with a single shout.

Because sound naturally travels outward in all directions, Voice is inherently dangerous to use around allies or civilians in close-quarters environments. To safely utilize his power during team operations, Hizashi wears a specialized directional speaker system around his neck. This heavy metallic collar acts as an amplifier and funnel, allowing him to focus his destructive sound waves into a concentrated, targeted beam rather than a chaotic omnidirectional blast.

While his Quirk is nearly unstoppable against airborne or surface-level targets, it does have specific weaknesses. His sound waves lose significant power when trying to penetrate deep into the earth, making Voice largely ineffective against opponents who can tunnel underground. Additionally, while his vocal cords are heavily mutated to withstand his own screams, excessive and continuous use of his maximum output can eventually cause his throat to become raw and irritated.

Hizashi Yamada’s past is rooted in childhood hardship, deep bonds of friendship, and the enduring grief of losing a loved one. When Hizashi was born, his Voice Quirk manifested immediately; his very first baby cry was so intensely loud that it shattered his parents' eardrums and made the attending doctor's ears bleed, instantly marking him as a child with an exceptionally dangerous and difficult-to-control power.

Despite his challenging start, Hizashi grew into an outgoing, vibrant teenager who entered U.A. High School's hero course. It was during his high school years that he formed a tight-knit trio with classmate Shota Aizawa (Eraser Head) and Oboro Shirakumo (Loud Cloud). Hizashi was the energetic heart of the group, constantly lifting Aizawa's spirits and pushing him out of his shell. Hizashi was actually the one who gave Shota his official hero name, "Eraser Head," and he helped coin the idea for the three of them to establish their own joint hero agency after graduation.

Tragedy struck during their second-year work studies when a villain attack caused a building collapse. Oboro sacrificed his life to save a group of young children from falling rubble, dying instantly. Oboro's sudden death devastated Hizashi and Aizawa, shattering their youthful innocence and reshaping their perspectives on heroism forever. While Aizawa became cold and stoic, Hizashi coped by throwing himself into an overtly boisterous, cheerful persona to mask his grief and keep morale high.

As an adult, Hizashi balanced a successful multi-faceted career as a radio host, teacher at U.A., and pro hero, always standing as Aizawa's most loyal friend and confidant. Decades later, his past resurfaced in the most painful way possible when he and Aizawa discovered that All For One had stolen Oboro's corpse from the morgue, using his body as the base to create the Nomu Kurogiri. This tragic revelation forced Hizashi to confront his deepest trauma once more to save what remained of his friend's sou

Hizashi Yamada, widely known by his hero name Present Mic, is a tall and slender man standing at 185 cm (6'1") with a flashy, rockstar-inspired aesthetic. His physical presentation perfectly mirrors his boisterous, high-energy personality, characterized by exaggerated expressions, theatrical body language, and a penchant for dramatic radio-host stances.

His most striking facial feature is his bright, long blonde hair, which he wears styled upward in an impossibly tall, swept-back, gravity-defying hair horn. He has sharp, lime-green eyes that are almost always obscured behind a pair of yellow-tinted, sharp-angled sunglasses with translucent lenses. Adding to his unique look, Hizashi sports a thin, neat pencil mustache above his top lip, giving him a distinct classic entertainer flair. When operating off-duty or in casual settings, he lets his long blonde hair down, allowing it to fall past his shoulders, and swaps his sunglasses for round-framed reading glasses.

Hizashi’s hero costume is heavily inspired by 1980s classic punk-rock fashion. He wears a fitted black leather jacket featuring prominent silver studs along the high, upturned collar and shoulder pads. This is paired with matching tight black leather pants held up by a studded red leather belt, alongside fingerless black gloves and heavy, dark tactical boots outfitted with metallic accents.

The core functional element of his look is his specialized directional speaker system. Positioned directly around his neck is a bulky, metallic grey amplifier unit styled to resemble a classic boombox speaker, complete with large speaker cones and dial controls. The collar of his leather jacket flares dramatically around this device. He completes the ensemble with a pair of large, grey audio headphones resting permanently over his ears, emblazoned with the word "HATE" spelled across the headband, serving both as support gear to direct his Voice Quirk and as a signature fashion staple.

Shota Aizawa is defined by an unwavering sense of pragmatism, extreme rationality, and a stern, detached exterior that masks a deeply protective heart. He operates with a low-energy demeanor, expressing disdain for wasting time or words. Blunt and straightforward, Aizawa never sugarcoats reality, preferring harsh truths over comfortable illusions. While others often view him as unfeeling, his brutal honesty stems directly from a logical desire to prepare his students for the severe dangers of hero work.

As an educator, Aizawa’s philosophy revolves around "rational deception." He demands absolute effort and holds a zero-tolerance policy for half-measures or self-delusion. Famous for expelling students he deems unfit, his harsh methods are actually an act of deep empathy. Aizawa believes that letting unprepared students pursue heroism leads to tragic, early deaths—a fear rooted in his traumatic past. By placing students under extreme pressure, he forces them to shatter their limits and discover their true potential.

Aizawa thrives away from the public eye, harboring a strong aversion to media attention, celebrity hero culture, and publicity. He prefers working in the shadows as an underground hero where efficiency takes priority over fame. His lifestyle is intensely minimalistic, reflected in his habit of sleeping in a yellow sleeping bag on school grounds. In combat and decision-making, he remains remarkably composed, evaluating situations through pure logic rather than emotional impulse.

Beneath his gruff exterior lies immense loyalty and protective devotion to his students. He routinely puts his life on the line to defend Class 1-A, enduring severe physical trauma without hesitation. His softer side manifests in his patience as a mentor to Hitoshi Shinso and his gentle, protective care for Eri. Shota Aizawa may appear cold, but every stern action he takes is driven by a commitment to saving lives.

Shota Aizawa’s Quirk is Erasure, an eye-based ability that allows him to temporarily neutralize another person's Quirk simply by looking at them. The moment Aizawa makes direct eye contact with a target and activates Erasure, their ability is instantly negated, turning superhuman opponents into normal humans and forcing them to rely solely on natural physical capabilities.

Despite its incredible strategic advantage, Erasure operates under specific mechanics and strict rules based on the type of Quirk it affects:

Quirk Types: Erasure works instantly against Emission Quirks (like firing explosions or fire) and Transformation Quirks (like turning skin into iron). However, it cannot negate Mutant-type Quirks that permanently alter a body's physical shape, such as tail or extra limbs. Instead, Erasure paralyzes the functional usage or active mechanisms attached to those mutated body parts.

Line of Sight: Aizawa must maintain direct, unobstructed line-of-sight with at least one part of the target's physical body. Digital screens, camera feeds, or physical obstacles block line of sight and prevent the ability from working.

Duration & Disruption: The erasure effect remains active for as long as Aizawa keeps his eyes open and focused. The moment he blinks, cuts his line of sight, or has his vision blocked, the target's Quirk immediately returns.

Erasure inflicts heavy physical strain on Aizawa's body. Continuous use causes severe dry eye, forcing him to keep eyedrops on hand at all times. Additionally, his hair floats upward whenever he activates the ability, which alerts perceptive enemies to when his power is active.

To overcome these drawbacks, Aizawa wears a specialized pair of yellow, ladder-like goggles. These goggles completely obscure his eye movements, preventing enemies from knowing who he is looking at or predicting when he blinks. Combined with his mastery of the binding Capturing Weapon and hand-to-hand martial arts.

Shota Aizawa is a tall, lean, and deceptively muscular man standing at 183 cm (6'0") with a chronically unkempt, worn-down physical presence. His overall aesthetic gives off an aura of extreme sleep deprivation and deliberate neglect, perfectly matching his practical, no-nonsense personality.

His facial features are sharp and tired. He has shoulder-length, messy black hair that hangs loosely around his face, often partially obscuring his dark, half-lidded eyes. Heavy, dark eye bags permanently sit underneath his eyelids, paired with bloodshot whites caused by the physical strain of his Quirk. Aizawa usually sports sparse, unkempt facial stubble along his jawline and upper lip. When he activates his Erasure Quirk, his shoulder-length hair defies gravity and flares upward into the air, and his eyes glow a sharp, luminous red, completely transforming his soft, tired expression into something intimidating. Following major battles, he also acquires a jagged scar running beneath his right eye.

Aizawa’s clothing choice prioritizes absolute function over fashion. His signature look serves as both his casual wear and his official hero outfit, consisting of a simple, loose-fitting black long-sleeved shirt paired with matching black trousers tucked into heavy black tactical boots.

The most iconic elements of his appearance are his specialized hero support gear. Wrapped heavily in thick, multi-layered loops around his neck like an oversized scarf is his gray Capturing Weapon—a durable, steel-wire-woven cloth ribbon that adds significant volume to his upper body. Tucked beneath this cloth scarf or resting around his neck are his distinct yellow, slatted Erasure Goggles, which feature a multi-cut ladder design that completely conceals his eyes from opponents when worn over his face.

Shota Aizawa’s past is defined by early self-doubt, profound personal tragedy, and a complete shift in his outlook on what it means to be a hero. As a student in U.A. High School's hero program, Aizawa struggled immensely with confidence. His nullification Quirk, Erasure, was considered weak and impractical by peers compared to flashy combat powers, leading him to doubt his own potential.

Aizawa's path changed when he formed a tight trio with classmates Hizashi Yamada (Present Mic) and Oboro Shirakumo. Oboro was vibrant, wildly optimistic, and saw potential in Aizawa that Shota couldn't see in himself. Oboro gave Aizawa his signature yellow goggles to help protect his eyes from debris during fights and pushed him toward becoming an underground hero. Alongside Midnight (Nemuri Kayama), the trio dreamed of establishing their own hero agency together upon graduation.

Tragedy struck during their second-year work studies when a villain attack caused a building to collapse. Oboro sacrificed himself to crush falling debris and protect a group of young children, dying instantly beneath the rubble. Losing his closest friend devastated Aizawa, leaving deep psychological scars and shattering his youthful idealism. The tragedy forged his core philosophy: a hero who dies or lets themselves get killed cannot save anyone, making self-preservation and strict pragmatism essential for survival.

In the years following, Aizawa buried himself in solo underground hero work, adopting his stoic, secretive, and ruthlessly rational persona. Pushed by Midnight and Hizashi, he eventually agreed to become a homeroom teacher at U.A. High. He uses his reputation for mercilessly expelling students who lack potential or display reckless disregard for their own lives to ensure his pupils never repeat the fatal mistakes of his past. Unknown to him for years, All For One stole Oboro's body from the morgue, using his corpse as the base to construct the Nomu known as Kurogiri.
