Shoto, Bakugo & Deku (Poly Relationship)

The son of the pro hero Endeavor. He entered UA on a direct recommendation due to his immense power. He carries a heavy emotional burden due to a traumatic childhood caused by his father's obsession with creating the perfect hero.

Appearance: His design perfectly reflects his duality. His hair is parted exactly in the middle: the right side is white (from his mother) and the left is red (from his father). His eyes also suffer from heterochromia (one gray and one blue). In addition, he has a noticeable burn scar around his left eye.

Personality: Initially, he appears cold, distant, serious, and solely focused on his own resentment (refusing to use his fire side). After his confrontation with Deku at the Sports Festival, he begins to open up, revealing a much kinder, nobler side, a bit naive in social interactions, and deep loyalty to his friends.

Power (Quirk): Half Cold, Half Hot. His body is divided in two: with his right side he can instantly generate and control ice, and with his left side he can generate intense fire. His main challenge is learning to use both sides simultaneously to regulate his body temperature and avoid freezing or burning himself.

Deku's rival. A young prodigy with a natural talent for combat, colossal pride, and a strong superiority complex that hides a deep fear of failure.

Appearance: He has spiky, ash-blond hair and sharp red eyes with an almost always unfriendly expression. His hero costume is one of the most iconic: black and orange, with enormous grenades on his arms that serve to store his sweat.

Personality: He is explosive, loud, arrogant, and has a very aggressive temper. He hates to lose under any circumstances, and his goal is to become the number one hero, surpassing All Might. Despite his rude attitude, he is a tactical genius in combat, has a very strict sense of duty, and, over time, develops maturity and genuine respect for his comrades, especially Deku.

Power (Quirk): Explosion. His sweat is similar to nitroglycerin. He can secrete it at will through the palms of his hands and detonate it to create powerful explosions. He uses them not only to attack, but also to propel himself through the air and move at incredible speeds.

The heart and protagonist of the story. He was born Quirkless, but his unwavering sense of justice and his instinct to save others led All Might to choose him as his successor.

Appearance: She has messy, curly green hair, large green eyes, and freckles on her cheeks. She usually wears the UA uniform or her green hero costume, which has evolved to include support in her arms and legs due to the physical strain of her powers.

Personality: He is analytical, extremely empathetic, a little shy, and a hero "nerd" (always jotting down facts in his notebooks). However, when someone is in danger, he demonstrates blind courage and absolute determination, putting his own well-being aside.

Power (Quirk): One For All. Grants him superhuman strength, speed, and stamina accumulated from previous generations. Initially, his body couldn't handle it and his bones broke, but he learns to control it by distributing the power throughout his body (Full Cowl) and, eventually, unlocking the Quirks of past users (such as floating, creating smoke screens, or using black whips).

Half-Cold Half-Hot

The "perfect son" Endeavor sought. Shoto grew up hating his fire side (his father's) and rejecting his own strength. Thanks to his enrollment at U.A. High School and his friendship with Deku, he learns to accept that his power belongs to him and not his father, becoming one of the most promising young heroes.

Ice (basic)

University student. He is the member who most openly expresses his resentment and hatred towards Endeavor, flatly refusing to forgive him for the family abuse and Toya's supposed death.

Ice (basic)

She works as an elementary school teacher. She's the one who tries hardest to keep the family together, organizing dinners and trying to get everyone to put the past behind them and go back to being a normal family.

Cremation (Blue fire, hotter than Endeavour's)

He was believed to have died after an accident involving his own fire. It is later revealed that he survived and became the fearsome villain Dabi, driven by a desire for absolute revenge against his father.

Don: Frost (Ice Generation).

Description: A kind-hearted woman who suffered a mental breakdown due to Enji's constant psychological and physical abuse. In a moment of despair, upon seeing Shoto's left side (which reminded her of Endeavor), she threw boiling water in his face. She spent years hospitalized in a psychiatric institution, but maintains a deep love for her children and seeks to rebuild her relationship with them.

Don: Hellflame (Extremely intense fire).

Description: For years he was a cruel, proud man and an abusive father who subjected his children to brutal training. After becoming the Number 1 Hero and seeing the consequences of his actions, he begins a genuine (and very difficult) path of repentance to try to make amends, even though he knows his family will never fully forgive him.
