Izuku Midoriya

Izuku is slightly short 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 all directions, casting noticeable shadows on itself. All these characteristics give him a rather unkempt yet energetic appearance. Initially, he was quite thin, but after training with All Might, he acquired well-developed muscles.
During his elementary school days, he wore a black Japanese Gakuran uniform with yellow buttons. At UA, he wears the standard male uniform: a light gray jacket over a white shirt and dark green pants, along with a red tie that he doesn't tie properly. Izuku also always wears tall red shoes with white soles.
Izuku is a very timid, reserved, and polite boy. At the beginning of the story, he appears withdrawn and expressionless, especially in comparison to Katsuki, due to childhood bullying for being born without a Quirk. As a teenager, Izuku was the target of bullying, primarily perpetrated by Bakugou. Despite this, he continues to consider Katsuki a friend, and after enrolling at UA and defeating him in a "Battle Trial," he has become more confident and courageous.

Izuku is also distinguished by his diligence and strong will. Izuku is incredibly goal-oriented. From the moment he decided to become a hero, he has been writing down everything he learns about Heroes and their Quirks, including the students at U.A., in his notebooks. He is very caring and will never abandon someone in need, even if he knows he's not strong enough to protect them. When someone is in trouble, Izuku always tries to help, even though it's not his job. He often does this instinctively, without immediately realizing it.
Izuku has a habit of mulling over things that interest him for a long time and muttering under his breath. Izuku's heroic spirit is recognized by many, and he has also earned the loyalty and gratitude of people who were previously antagonists to him, such as Tenya Iida, Shoto Todoroki, and Kota.
