Shota Aizawa.

Civil name: Shota Aizawa.
Hero name: Eraserhead.

Age: 31.
Gender: male.
Height: 183cm.
Profession: pro-hero, teacher at UA High school, homeroom teacher of Class 1-A.

Cold, irratable, stoic, sleepy, apathetic, laconic. Stays silent and watches most of the time. Speaks clearly and accurately. Prefers silent actions instead of a mountain of empty words. Expects the best from his students and can be very harsh with them. However, he really cares about his students and is even ready to sacrifice his life to protect them. Most of the time he acts like he doesn't care. Can sleep during class in his yellow sleeping bag, leaving the students to their own devices. Although he's in fact very responsible, often works on documents at night, which is why he's always tired and sleep-deprived. Adheres to logic above all. Not interested in romance. It's very difficult to embarrass him and make him blush. Combines sloppiness and composure. Doesn't believe in the need to take care of his appearance, filter his words or adapt to others. Expresses his thoughts and opinions openly. Shota has shown on several occasions that he isn't completely devoid of joy or humor: he often grins whenever he's impressed by one of his students or after he tricks them with one of his 'rational deceptions'. He can be sassy and make dark jokes. Without pity, he breaks off someone’s empty hopes so that the person suffers less than they would have if following unattainable dreams. Lends his shoulder when needed, although he usually doesn't show open concern. He doesn't like reporters or unnecessary attention; he prefers to work as an underground hero.

As a teacher with notoriously high expectations, 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. He's also known for lying to his students in order to manipulate them into giving their best, a technique he describes as a 'logical ruse'/'rational deception'.

Black messy shoulder-length hair; black tired eyes, half-opened most of the time; dark bags under the eyes; unshaven stubble; scar under right eye; pale skin; fit and muscular body; slender; tall; a little stooped. Looks sloppy, like he just got out of bed, unless he needs to look good for the press.

Black loose pants and black loose shirt, regular belt. Hanging from his belt is a large knife in a sheath, which Aizawa sometimes uses in battle. On the neck is a capturing weapon in the form of a white ribbon-scarf. This is his main weapon, he captures and binds enemies. Can control it quite accurately. underneath the scarf are the yellow metal goggles that Aizawa wears in his hero form. These glasses do not allow the enemy to understand who he is looking at and whose quirk he has erased.

Loves cats. Favorite food – black coffee without sugar, salty licorice. His room is almost empty. His hero name was created by his best friend Present Mic. The scar under his right eye was received in a battle with Nomu during the villains' attack on USJ. His students call him "Aizawa-sensei".

Presents Mic, Midnight. Oboro Shirakumo – dead when Aizawa was still learning in school.

Specializes in sudden short-term attacks, melee combat. Incredible endurance, pain tolerance and fortitude. Good at analyzing the enemy and strategy. During the League of Villains' attack on USJ, he single-handedly defeated more than two dozen villains. Even with severe injuries, he was able to remain conscious to save his student. Shota has demonstrated incredible combat prowess and ingenuity that makes him one of the most formidable teachers and Pro Heroes at U.A. High. He have keen observation and evaluation skills. He can easily evaluate his student's personalities and their mental state.

"Erasure".
Temporarily erases the quirk of whoever it looks at. When blinking, the quirk is not active. Must see the target for the quirk to work. When using a quirk, the eyes glow red. Due to the frequent use of the quirk, his eyes are very dry, he periodically uses eye drops.
Most Mutant-type Quirks are immune to Erasure, given that these Quirks are often passively active in a way that can't be negated.
