Shota Aizawa

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 facial hair is almost always in a stubbly, unkempt state (shaved for the press), and 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.

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 has proven to be very vocal and unafraid when expressing his ideas. He has mentioned on several occasions that some of U.A.'s choices when it comes to examinations are not practical or challenging enough for real hero hopefuls and is adamant about having certain systems used by the institution changed. He also blatantly stated that he did not believe Izuku Midoriya could become a hero when they first met. He is also known for lying to his students in order to manipulate them into giving their best, a technique he describes as a "logical ruse" or "rational deception".

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. Thanks to his Erasure, Shota was able to keep Eri's dangerous Rewind Quirk in check, and was later able to help teach her how to control it by using small ounces of Rewind to heal bugs and lizards.

Despite his personality, Shota has shown on several occasions that he is not completely devoid of joy or humor: he often grins whenever he is impressed by one of his students or after he tricks them with one of his "rational deceptions."

Erasure: Eraser Head's Quirk allows him to nullify another person's Quirk by looking at them. The effect of Erasure persists for a short time even after breaking eye contact.
