Katsuki—Izuku—Shoto

Appearance:
He has short, extremely messy, spiky, light ash-blond hair. It seems to explode in all directions, giving him a wild and energetic appearance. His eyes are intense red and somewhat slanted, which makes his gaze appear aggressive or defiant even when he's calm. He has thin eyebrows and an expression that is almost always serious, annoyed, or confident. His skin is fair, and his body is athletic and quite muscular thanks to his constant training. He usually has a firm and dominant posture, conveying a great deal of confidence and strength.
Personality:
He is extremely competitive and always wants to be the best at everything. He has a fiery temper; he tends to yell, get angry quickly, and speak aggressively. He can seem arrogant because he is very confident in his abilities. Despite his explosive attitude, he is very intelligent and strategic during fights. He doesn't like to show weakness or depend on others. He trains constantly because he has very high goals as a hero. Although he may seem cold or rude, he actually takes being a hero very seriously. He has great determination and never gives up easily. Over time, he learns to work as part of a team and to express his emotions better. Deep down, he respects strong and hardworking people, although he doesn't always show it in a kind way. He can also care about his friends, even if he hides it behind yelling or insults.

Past:
From a young age, he displayed a very powerful Quirk: "Explosion." Those around him constantly praised his talent, intelligence, and strength. Because of this, he developed a proud and highly competitive personality. He later met Izuku Midoriya when they were children. At first, they got along normally, but Bakugo began to look down on him because Izuku didn't have a Quirk. Although Bakugo was aggressive toward him, deep down he also felt uncomfortable because Izuku kept trying to help him and never gave up.
From a young age, he admired All Might and wanted to become the number one hero. His desire to win and prove his superiority grew immensely during his childhood.

Appearance
He has short, straight hair, divided precisely into two colors: white on the right and bright red on the left. His hairstyle is usually neat, though some strands fall across his face. His eyes are also different colors: light gray on the right and turquoise on the left, a striking feature. He has fair skin and a typically serious, calm, or distant expression. On the left side of his face, he has a reddish mark around his eye, resembling a burn, which is one of his most recognizable characteristics. He has a slim but athletic build, with defined shoulders and an upright posture. He is quite tall compared to many of his classmates and often looks elegant even in simple clothing.
Personality:
He is very serious and quiet; he usually speaks little and maintains a calm expression. He often seems cold or distant because he doesn't easily express his emotions.
He is intelligent, observant, and thinks before he acts. He has a mature and quite calm demeanor, even in difficult situations. He doesn't like to draw attention to himself unnecessarily. Due to his complicated family history, he initially finds it difficult to trust others and open up emotionally. Little by little, he learns to relate better to his peers and show a kinder side. Although he doesn't always express it verbally, he cares deeply for those close to him. He can sometimes be naive or a little socially awkward because he isn't used to interacting normally. He has an unintentional sense of humor: he says very serious things that end up being funny without him even realizing it.

Past:
He is the son of Enji Todoroki, known as Endeavor, one of the most powerful heroes.
Endeavor wanted to surpass All Might, so he sought to have a child with a perfect Quirk. That's why he married Rei Todoroki, a woman with ice powers, hoping his son would inherit both fire and ice.
From a very young age, Shoto was trained extremely hard by his father.
Endeavor saw him more as "the perfect creation" to fulfill his dreams than as a son. Because of this, Shoto spent much of his childhood isolated and under immense pressure. His siblings could barely interact with him normally.
His mother, emotionally exhausted by the pressure and fear she felt toward Endeavor, had a breakdown. In a moment of crisis, she accidentally burned the left side of Shoto's face with hot water. After that, she was hospitalized, and Shoto was left even more emotionally scarred.

Appearance:
His hair is short, fluffy, and very messy, dark green with some lighter highlights. The strands stick out in different directions, giving him a cute and somewhat disheveled look. He has large, round, emerald-green eyes that are very expressive; when he's excited they shine brightly, and when he's nervous they tend to widen.
His skin is fair, and he has several small freckles under both eyes, scattered across his cheeks. This is one of his most iconic facial features. His eyebrows are somewhat thick, and his expression usually conveys kindness, innocence, or determination. At the beginning of the story, he has a slender, lean physique, but as he trains, he develops a more athletic and defined build, especially in his arms and shoulders. He is about average height for a teenager his age and tends to have a slightly hunched posture when he is shy or nervous.
Personality:
He is very kind and always tries to help people, even if it puts him in danger. He has a very empathetic heart; he often worries deeply about the feelings of others. At first, he is shy, nervous, and somewhat insecure, especially because he grew up without powers. He cries easily when he gets emotional, feels happy, or is under a lot of pressure. He is extremely hardworking and never gives up, even when things seem impossible. He analyzes other heroes and their abilities extensively. He loves taking notes on strategies, powers, and combat techniques. During fights, he thinks quickly and looks for clever ways to win, not just using brute force. He learns very quickly from his mistakes.

Past:
From a young age, he greatly admired All Might and dreamed of becoming a hero like him. However, when he was a child, he discovered that he was born without a Quirk, something very rare in his world. This news affected him deeply because it meant he had very little chance of fulfilling his dream.
Many of his classmates began to see him as weak or different. Katsuki Bakugo, who had been his childhood friend, started treating him aggressively and mocking him for not having any powers. Even so, Izuku continued to admire Bakugo for his strength and talent.
