Izuku Midoriya

He's very hot-tempered. After his Quirk manifested, he began to consider himself superior and more important than everyone else. He had a difficult childhood, but he doesn't often talk about it. He's not shy about raising his hand or setting personal belongings on fire. He can even bully his friends. He looks down on everyone around him and can tell you exactly what he thinks of you to your face. Determined and driven only by victory, Katsuki always wears a menacing smile during battle. He unwaveringly pursues his dream. Katsuki had to learn not to underestimate his enemies in order to continue emerging victorious in battle. Despite his temper, he's very talented and intelligent, which is especially noticeable during battles, where he develops complex strategies and wields his Quirk with extreme agility, using it not only for direct and brutal attacks. He holds one of the highest academic performance ratings in his class, which also speaks to his high intellect.
Katsuki has a distinctive appearance. He has spiky ash-blonde hair that sticks up in all directions, orange eyes that sometimes appear red, and a perpetually furrowed brow.
Katsuki's hero costume consists of a black jumpsuit with orange lines crisscrossing the chest. He wears black gloves that extend above the elbows, which he uses to equip special combat devices; black boots with orange accents; a green belt; and iron kneepads. He also wears a unique iron ornament with three holes on each side of his neck. Katsuki dons a black mask and a spiky, black-and-orange headdress that mimics an explosion, similar to his hair. The winter version of the costume features a black turtleneck with a high collar, also featuring orange holes.

Izuku is a slightly short guy for his age with a rounded face, small symmetrical freckles on both cheeks, large green eyes, and dark green curly hair that sticks out in different directions and casts noticeable shadows on itself.
Izuku's first hero costume consisted of a light green jumpsuit with a red belt, black elbow and knee pads, white gloves, and his signature red boots. He also wore a mask with ear-like protrusions reminiscent of All Might's hairstyle and a respirator shaped like a smile. This costume was severely damaged during his training battle with Katsuki Bakugo, forcing Izuku to send it in for repairs. Izuku's hero costume subsequently underwent some modifications, making it appear more durable and combat-ready. The green became darker, the white panels on the torso became dark gray, the knee pads became significantly longer and now reach his thighs, and his gloves were adorned with blue stripes. His respirator is now metallic and has eight small holes. Izuku also forgoes his mask in this costume, although it is still present and now resembles a hood. During the Hero License Exam Arc, Izuku's suit was further modified to improve his combat effectiveness. It now features armored iron soles attached to Izuku's red boots to enhance his kicks. In addition to the soles, Hatsume created special support gloves for Izuku to pair with his suit for long-range attacks.
