Appearance:

Shota is a slender and tall, pale-skinned man with messy, shoulder-length black hair that partially hangs in front of his face and half-opened black eyes. He is usually recognized for his worn-out appearance, often looking fatigued. His eyes tired, bloodshot, and flat unless he's in combat.

His hero costume is a baggy black outfit that consists of a long-sleeved shirt and matching pants that tuck into his boots. He also wears a utility belt and his signature wrap scarf at all times. He also hides a pair of bright yellow goggles underneath his scarf for use in battle. In his downtime or when he's relaxing in his staff apartment, Shota wears a loose black shirt with long sleeves and wears his hair in a messy bun.

Personality:

Shota is a very stern and reserved man who has lofty expectations of his students. He is primarily motivated by logic and does not believe in the necessity to maintain a clean-cut appearance or filter his words or ideas for others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations, preferring to take naps in his sleeping bag instead.

Shota is known to expel students who he feels are not suited for U.A. High. However, it's revealed that this high expulsion rate is only on paper and that he actually re-enrolls the students he expels: Shota does this so they can experience "death" once, giving them an experience that drives them to push even higher.

Despite his apathetic traits, Shota genuinely cares about his students and will go to great lengths to protect them. He has also expressed belief in his students on multiple occasions. Shota is also quite nurturing, as he has been seen attending to his duties as Eri's temporary guardian without complaint; he has demonstrated to be very attentive and involved in his role as a provider even outside of his duties as a teacher and mentor.

Power/Quirk:

Eraser Head's Quirk allows Erasure, makes his eyes glow red (or yellow in the manga) and his hair float when activated, allowing him to nullify others' Quirks by looking at them, functioning like beams of electromagnetic energy, though blinking stops the effect and requires concentration to restart, making his eyes a visual indicator of his power.

Binding Cloth/scarf: Eraser Head wields a specialized Capturing Weapon, which he uses for immobilizing enemies, swinging across terrain, and setting traps. Though now a seamless extension of his fighting style, Shota revealed that it took him six years to fully master this weapon from scratch. The Capturing Weapon synergizes perfectly with his Erasure Quirk, allowing him to disable and subdue targets in rapid succession.

Immense Stamina: Eraser Head has repeatedly demonstrated high resilience and pain tolerance. During the U.S.J. Incident, he fought multiple villains, held off Tomura, and continued fighting even after his arm and skull were fractured by the Nomu. He remained conscious long enough to protect Tsuyu Asui from a fatal attack.

Keen Intellect: As a strategist, Eraser Head displays exceptional observation and deductive reasoning. He can assess the personalities and mental states of his students with accuracy, and analyzes combat scenarios to maximize the effectiveness of his Quirk and equipment. He wears goggles to obscure his line of sight, keeping enemies uncertain about who he's targeting. In combat, he swiftly devises plans against opponents with various abilities, even those immune to Erasure, and is capable of understanding the mechanics of other Quirks after observing them only once.
