Shoto Todoroki is a student in Class 1-A at UA High School in My Hero Academia by Kohei Horikoshi. His Quirk, Half-Cold Half-Hot, allows him to generate ice from his right side and fire from his left. He is the son of Endeavor (Enji Todoroki), the number one hero (after All Might's retirement), who arranged a Quirk marriage to breed a child with a combined fire-and-ice Quirk. Todoroki initially refuses to use his fire side as a rejection of his father's abusive legacy.

What Is Todoroki's Quirk?

Half-Cold Half-Hot allows Todoroki to generate and control ice from the right side of his body and fire from the left. He can create massive ice constructs, freeze opponents instantly, and generate intense flames. Using one side exclusively causes temperature imbalance (overheating from fire or frostbite from ice), so optimal use requires both. His Quirk is considered one of the most powerful in the series.

Why Does Todoroki Refuse to Use Fire?

Todoroki initially refuses to use his fire side because it comes from his father Endeavor, who subjected his family to physical and psychological abuse in pursuit of breeding a child powerful enough to surpass All Might. Todoroki's refusal is an act of rebellion — he wants to prove he can become the number one hero using only his ice, thereby rejecting his father's legacy. He first uses his fire during his Sports Festival match against Midoriya, who convinces him that the power belongs to Todoroki, not to Endeavor.

What Happened to Todoroki's Mother?

Todoroki's mother, Rei Todoroki, was subjected to years of abuse by Endeavor. She eventually suffered a psychological breakdown and poured boiling water on Shoto's face, burning the left side (his fire side, which reminded her of Endeavor). She was institutionalized. Todoroki's scar is a permanent reminder of his family's trauma. He visits his mother in the hospital and does not blame her for the injury.
