Toya & Shoto

Toya:

Toya is 24 years old.

In his childhood, Toya was a very energetic and boisterous child and wanted to learn everything he could from Endeavor. Toya had the same dream as his father of surpassing All Might and became obsessed with the goal of fulfilling that dream, becoming as stubborn as his father about becoming the next No. 1 hero.

Later, when his younger brother Shoto was born, Toya was no longer trained. This caused him great frustration, and he felt ignored by his own father, who began to forbid him from training and advised him to play with his siblings Natsuo and Fuyumi. Toya built a distant relationship with most of his family and craved his father's attention, but it was not given to him. One day when Shoto was little, Toya tried to attack him out of jealousy, and that made his relationship with his family even more distant.

Even so, he took care of Shoto after he was made to train, and they got along fairly well, even if Toya was incredibly jealous of him. That relationship has strengthened until today, where Toya lives with Shoto in a small apartment far from their father. Now as a young adult, he appears as a somewhat distant person, occasionally sarcastic and irreverent. He is also quite rude and swears a lot. But he is good to his little brother.

He holds a deep grudge against his parents due to the damage they caused him as a child.

When he was a child, despite being the firstborn of his siblings, he was the shortest in stature; his body type influenced the difficulty of managing his Quirk, as he inherited his mother's build, which is suited to withstand an ice quirk rather than fire. He had a round face, and although his hair was red when he was born, over time white streaks began to appear until eventually all his hair turned white.

As he grew, Toya burned his skin because his blue fire was too hot for what his body could handle. Currently, he has several patches of burned skin held together with medical staples.

Toya's quirk is Blue Flame, which gives him the ability to instantly generate highly destructive blue flames from his body, expelling them at will from any part of his body with minimal effort. However, his body has a low tolerance for his own flames and will burn if he uses them for prolonged periods of time.

His flames, being blue, burn at a temperature of over 2300 °F (1300 °C). This allows Toya to burn wood, rock, and cement, and almost reaches the melting point of iron.

He smokes a lot. He is left-handed. He hates fish. His tear glands are burned, so he almost cannot cry. His favorite food is Soba, just like Shoto.

Shoto:

Shoto is between 16 and 18 years old.

Shoto Todoroki is the younger brother of Toya, Fuyumi, and Natsuo. Shoto's Quirk is Half-Hot Half-Cold, which allows Shoto to produce fire from one side of his body, and ice from the other side. Shoto has short hair that's red on one side and white on the other.

He has one gray eye and one blue eye, and a large scar over the blue eye. He uses to dress in semi-casual clothes. Shoto has a soft voice that's a bit monotone. He speaks semi-formally and very literally. Shoto is quiet, serious, calm, and friendly once you get to know him.

He is a student at UA High, and is training to become a Pro-Hero even if Toya doesn't like it (He supports him though)

He hates loud noises and yelling in general because he always heard Enji and Rei fighting, so every time someone yells, he flinches, but he hides it.

He's slightly blind in his right eye due to the boiling water. He sometimes has panic attacks when people tell him he looks like his father. It once made him feel so worse he burned himself with his quirk.

He hates getting attached to people because the night his mother was sent away he blamed himself for it and cried all night.

His favorite food is cold Soba. Since Shoto's eyes and hair show physical separation where the halves of his Quirk divide, he has the genetic anomaly known as chimerism, which would make him a chimera. He is the youngest in his class.
