Eye drops: Shota carries a small green case of eye drops. He uses them to treat dry eyes caused by keeping his eyes open for too long.

Capture Weapon (捕縛武器, Hobaku Buki ? ) : Eraser Head's preferred weapon is a cloth made of steel wire alloy woven with carbon nanofibers.

Eraser Glasses: Eraser Head is recognized by the golden glasses he wears around his neck, hidden by his scarf. These glasses complement his Quirk, obscuring his line of sight and preventing enemies from accurately determining which Quirk has been erased. He received the glasses during his school years with Oboro.

High-density weights: Eraser Head and the rest of the teachers use these wristbands to give themselves an advantage while fighting against their students.

Caltrops: Eraser Head used caltrops in the practice battle against Team Todoroki and Yaoyorozu. They were effective when combined with the Capture Gun. After suspending Shoto in the air with the Capture Gun, Shota threw caltrops beneath him so that he couldn't land safely if he escaped his restraints.

Knife: Eraser Head has a large knife that he uses to cut his Capture Weapon if it gets stuck on something. He can also use it in combat.

Eraser Head's Gift allows him to nullify another person's Gift simply by looking at them. The effect of Erasure lingers briefly, even after breaking eye contact. After suffering severe injuries during the USJ Incident, Eraser Head can no longer hold the Eraser for extended periods and requires longer breaks between uses. The erase function is deactivated when Shota flashes. Prolonged use causes dry eyes, leading to more frequent blinking and shorter activation windows. Most Mutant-type Quirks are unaffected, as their effects are permanent and physical. The erasure has no impact on innate physical abilities or enhancements that are not based on Gifts. When active, Erasure makes Shota's hair levitate, which is a visual cue that opponents can use to gauge activation. The Quirk has no inherent offensive capability. Since Shota's Quirk Factor is linked to his eyes, any serious injury to them could reduce or eliminate his ability to use Erasure effectively.

Immense Resilience: Eraser Head has repeatedly demonstrated great resilience and pain tolerance. During the USJ Incident, he fought multiple villains, held off Tomura, and continued fighting even after the Nomu fractured his arm and skull. He remained conscious long enough to protect Tsuyu Asui from a fatal attack. At the climax of the Paranormal Liberation War, Shota amputated his leg to prevent the full effects of a Quirk-Destroying Bullet from manifesting, yet he still managed to use Erasure despite his injury.

Keen Intellect: As a strategist, Eraser Head displays exceptional observation and deductive reasoning. He can accurately assess his students' personalities and mental states and analyzes combat scenarios to maximize the effectiveness of his Quirk and equipment. He wears protective goggles to conceal his line of sight, preventing enemies from knowing who he is targeting. In combat, he quickly devises plans against opponents with diverse abilities, even those immune to Erasure, and is able to grasp the mechanics of other Quirks after observing them only once.

Teaching Ability: Though initially reluctant to become a teacher (after being hired by Nemuri Kayama), Shota has become one of the most effective educators in the Hero Course. He teaches with complete honesty and strict expectations, emphasizing the serious responsibilities that come with being a Pro Hero. One of his signature methods is using "rational deceptions," such as the threat of expulsion, to push students beyond their perceived limits. Along with All Might and the rest of the U.A. faculty, he has trained Class 1-A into a highly skilled group of aspiring heroes.

Shota is a very stern and reserved man who has high expectations of his students. His primary motivation is logic, and he doesn't believe in the need to maintain a flawless appearance or filter his words or ideas for others. He often appears cold, apathetic, and impatient, displaying very little energy in most situations and preferring to nap in his sleeping bag. As a teacher with notoriously high expectations, Shota is known for expelling students he deems unfit for U.A. High School. However, it is revealed that this high expulsion rate is only theoretical and that he actually re-enrolls the students he expels: Shota does this so they can experience "death" once, providing them with an experience that motivates them to strive even harder,[14] though it should be noted that he has yet to expel any students from Class 1-A, despite being well-known for doing so.[15] He can be rigid and strict when necessary and has little tolerance for disobedience. Shota is not afraid to subject his students to rigorous training and often emphasizes the more unpleasant aspects of heroism so that they can overcome their limits. Shota has proven to be very outspoken and courageous in expressing his opinions. He has mentioned on several occasions that some of UA's exam decisions are neither practical nor challenging enough for true aspiring heroes, and he is adamant about the need to change certain systems within the institution. He also openly stated that he didn't believe Izuku Midoriya could become a hero when they first met. He is also known for lying to his students to manipulate them into giving their best, a technique he describes as a "logical trick" or "rational deception."

Shota is a tall, thin man with pale skin, shoulder-length, messy black hair that partially covers his face, and half-closed black eyes. He is usually recognized by his gaunt, often fatigued appearance. His facial hair is almost always unkempt and disheveled (unless he needs to look presentable to the press), and his gaze is tired and dull, unless he is in combat. He wears a loose-fitting black suit consisting of a long-sleeved shirt and matching trousers tucked into his boots. He also wears a utility belt and his signature scarf at all times. Eraser Head hides a pair of glowing yellow goggles beneath his scarf for use in combat.
