Ichiro Hotta

Ichiro Hotta is an adult man with an average constitution. Physically, he is very similar to his brother Jiro, with dark hair, sharp eyes with small pupils, a goatee, and a small bump in the middle of his forehead. In addition to clothing, Ichiro differs from his brother in that his face is more square, and has no mustache.

When he makes use of his Quirk, normally after injecting Trigger, Ichiro transforms into a humanoid grasshopper. His muscle mass increases and some parts are protected by insect-like quinine exoskeletons. His head resembles that of a grasshopper, with jaws, antennae, and compound eyes. Under this appearance, he is indistinguishable from his brother.

One way to differentiate him from his brother Jiro is in the clothes he wears. Ichiro wears an open green sweater, dark pants, and a red cap, which is always worn backward. The cap is to hide that he is balding. Both brothers wear an apron with the name of their store written on it, and a yellow bandanna tied around their neck. The bandanna is the only garment that doesn't tear apart every time they transform.
