A serious but well-meaning student enrolled by recommendation, Shoto is the son of Endeavor (Enji Todoroki), a famous hero ranking behind only All Might himself.

His Quirk is "Half-Cold Half-Hot", which allows him to generate and control large amounts of fire and ice from his left and right sides respectively, the former of which he inherited from his father and the latter from his mother.

Raised by Endeavor for the sole purpose of surpassing All Might, Todoroki hates how his father only views him as a tool and had originally vowed to become the number one hero without ever using his fire abilities as a form of rebellion.
