Even without his Quirk, Eijiro has above-average durability. According to Katsuki, even though Eijiro took a barrage of direct blasts during their fight at the sports festival, it wasn't just due to Eijiro's armored skin. This assertion proves that Eijiro's natural durability is quite strong, but can be enhanced by hardening.

Eijiro is a cheerful, loud, and outgoing guy. He has a strong bias towards the concept of masculinity - for example, he uses the words "manly" and "unmanly" to describe what he likes and dislikes, and is fixated on "manly" actions. Anyone who demonstrates bravery, nobility, or determination in his presence will earn his boundless admiration and respect, and vice versa. He is also a big fan of the retro hero Scarlet Riot. He even chose his hero name in his honor.

Eijiro is honest, kind, and straightforward. Judging by the fact that he is one of the few who communicates normally with Bakugo, he makes friends easily. For the sake of his friends or even just acquaintances, he is ready to do anything, even break the law, and is very worried if he cannot somehow help them.

Eijiro's appearance is quite ordinary, except for his red-dyed hair, styled so that it resembles a cluster of small, sharp spikes. This isn't his natural hair color. He started dyeing it before entering UA. During middle school, his hairstyle was completely normal—straight, slightly tousled, black (natural) hair. He has a scar above his right eye, which he acquired as a child after unexpectedly activating his Quirk. His teeth are sharply pointed, giving him a slightly aggressive appearance. Despite his young age, he also possesses an impressive build.
