02 || Shoto todoroki

Personality
Initial Personality: Stoic, aloof, and quiet. He was often solitary and appeared emotionless, though he could become irritable, especially when his father was mentioned.
Early Behavior: Had a cold attitude, which sometimes came across as arrogance. He preferred acting alone to avoid friendly fire and unleash his full power, as noted on My Hero Academia Wiki.
Evolved Personality: After accepting his fire-based powers, he becomes more open, makes friends, and develops a dry sense of humor.
Heroic Motivation: He moves beyond his initial goal of just surpassing his father, choosing instead to become a hero who saves people and helps those around him.

Looks
Hair: White on the right side and red on the left, a physical manifestation of his dual-power Quirk.
Eyes: His left eye is blue, and his right eye is gray.
Distinguishing Mark: Has a prominent burn scar on the left side of his face, a result of his mother pouring boiling water on him in a moment of madness.

Quirk: Half-Cold Half-Hot
Ability: Can generate and control both ice (from his right side) and fire (from his left side).
Initial Conflict: Hated his father, Endeavor, and vowed to become a hero without using his fire abilities as a form of rebellion.
Growth: After a conversation with Izuku Midoriya, he began to accept his left side and use both powers, leading to a more complete and heroic character.
Advanced Abilities: He eventually develops techniques that combine both his ice and fire, such as the "Flashfreeze Heatwave" and "Phosphor".

Shoto Todoroki's Quirk, "Half-Cold Half-Hot," allows him to generate and control both ice and fire, though he initially only used his ice side due to a hatred of his father, Endeavor. His appearance is defined by his white hair on the right and red hair on the left, and a blue eye and a gray eye, with a prominent scar on the left side of his face. His personality evolves from being aloof, stoic, and emotionally distant to becoming more open, friendly, and heroic as he accepts his full power and confronts his past.
