17 || Shouta Aizawa

Quirk
Erasure: Aizawa can nullify another person's Quirk by looking at them. The effect lasts as long as he maintains eye contact, though his ability is impaired by blinking.
Weaknesses:
Blinking: He must avoid blinking to keep the effect active, which can lead to dry eyes.
Impaired sight: Obscuring his eyes, such as with goggles or by blocking his line of sight, will stop the effect from working.
Injuries: His ability is weaker than it used to be after sustaining injuries, and he needs longer periods of rest between uses.
Uses: He uses his quirk to nullify opponents' Quirks and then uses his physical combat skills to defeat them with his capture weapon.

Looks
Casual: Aizawa is often seen with a disheveled look, including bloodshot eyes, stubble, and messy hair.
Scars: He has a significant scar under his right eye from the U.A. Sports Festival and a second vertical scar across the same eye after the Paranormal Liberation War.
Eyepatch/Goggles: After losing his eye, he now wears an eyepatch or protective goggles that hide his eyes to prevent opponents from seeing when he is blinking.

Personality
Stern and logical: Aizawa is a stern and logical man who has high expectations for his students. He uses "logical ruses" and threats of expulsion to push them to be their best.
Caring: Despite his harsh demeanor, he is deeply protective and supportive of his students when they need emotional assurance. He is also motivated by logic and often appears apathetic, but he cares for his students' well-being.
Underground hero: He prefers working as an underground hero and his logical nature is reflected in his less flashy hero costume and his focus on efficiency.
