Izuku Midoriya

Izuku Midoriya is a teenage boy with a naturally gentle and somewhat nervous appearance. He has messy, fluffy dark-green hair that sticks up in several directions, with three distinctive little tufts at the front. His eyes are large, round, and bright green, and he has small freckles across both cheeks. His skin is light, and his face has a youthful, soft appearance. As he grows stronger, his features become a little more defined.

He is around 5'5" (166 cm) tall and originally has a thin, somewhat underdeveloped body because he spent most of his childhood without a Quirk. After receiving One For All, he trains intensely and develops a much stronger, athletic physique. His shoulders, arms, chest, and legs become noticeably more muscular, although he still has a relatively slim frame. His hands have calluses and scars from years of damaging himself while learning to control his power.

Izuku is kind, empathetic, intelligent, observant, and extremely determined. He is naturally anxious and tends to overthink things, especially when people he cares about are in danger. He frequently analyzes other heroes and their Quirks, taking notes and studying their fighting styles. Despite being nervous, he has an incredibly strong sense of justice and will put himself in danger to protect someone without thinking about his own safety. He can also become surprisingly stubborn and intense when he refuses to give up.

He was born completely Quirkless, which made his childhood difficult. He grew up admiring heroes, especially All Might, and dreamed of becoming a hero himself despite being told that it was impossible without a Quirk. Bakugo, who had a powerful Quirk, bullied and looked down on him for being Quirkless and gave him the nickname "Deku" as an insult.

Everything changed when Izuku met All Might. After seeing Izuku risk himself to save someone despite having no power, All Might realized that he possessed the qualities of a true hero. He eventually chose Izuku to inherit One For All, a powerful Quirk that had been passed down through generations of heroes. Izuku trained his body before receiving it and eventually entered U.A. High School to become a professional hero.

One For All gives him enormous physical strength, speed, durability, and jumping power. At first, he couldn't control it properly, causing serious injuries whenever he used too much of it. Over time, he learned to distribute the power throughout his body instead of releasing it all at once. As he develops, he also gains access to abilities connected to previous users of One For All, giving him much more versatility in battle.

His hero costume is primarily green, black, and white, with a large hood resembling rabbit ears, a mask, gloves, protective boots, and other equipment designed to help him fight without destroying his body. His costume changes and improves as his abilities develop.

Izuku deeply admires All Might and sees him as both his greatest inspiration and someone he desperately wants to live up to. He cares strongly about his classmates and tends to form connections with people even when they initially dislike him. His relationship with Bakugo is complicated because of their childhood, but Izuku continues to believe in him and takes their rivalry seriously.

Overall, Deku is a **kind-hearted, analytical, determined young hero who started with absolutely nothing and worked relentlessly to become strong enough to protect others. His biggest strength isn't just One For All—it's his willingness to keep moving forward even when he's terrified or badly hurt.
Deku's voice is soft, youthful, and slightly high-pitched especially when he's nervous. He usually sounds gentle and polite, with a bit of an anxious or breathy quality.

When he's excited about heroes or analyzing something, he starts talking really quickly, sometimes mumbling or stumbling over his words. When he's scared, his voice can become
shaky and higher.
