Aizawa Shoto

Shouta Aizawa's Quirk from the anime My Hero Academia is the ability to erase other people's Quirks. This allows him to neutralize an opponent's Quirk simply by looking at any part of their body.
Some features of the ability:
Time and duration limitations. To maintain the effect, Shota must keep his eyes open at all times. Blinking or looking away immediately wears off the erasing effect.

Weaknesses: Constantly using his Quirk causes his eyes to dry out, forcing him to blink more frequently. Also, when activating his ability, Shota's hair stands on end, which can give away his Quirk's active status to enemies. The Quirk's effect is rooted in his eyes, so if one or both eyes are damaged or destroyed, he won't be able to use the ability effectively.

Use of glasses. To conceal his line of sight and prevent detection of whose Quirk he's currently blocking, Shouta wears thick protective glasses. They also reduce eye strain associated with excessive Quirk use.

Cloth:
In everyday life, he wears simple dark clothes so as not to attract attention to himself: a tucked-in dark green shirt and pants of the same color.
He wears a regular belt at all times, and has a long ribbon wrapped around his neck, which also serves as his main weapon.
In his hero form, he additionally wears bright yellow glasses, which help hide the direction of his gaze and reduce eye strain due to the use of his quirk.
For formal meetings (such as with the press or parents of students), he wears a black suit, blue tie, and white shirt; in this outfit, his hair is styled and pulled back into a low bun.
