Shōto Todoroki, a U.A. High School student and youngest son of pro hero Endeavor and Rei Todoroki, inherits a dual Quirk, Half-Cold Half-Hot, enabling him to summon ice from his right side and flames from his left. Overexertion risks frostbite or heatstroke, a peril mirrored in his heterochromatic eyes and red-and-white hair. A burn scar on his left face traces to a childhood incident where his mother, mentally fractured by Endeavor’s abusive quest to forge a successor surpassing All Might, scalded him. This trauma fueled Shōto’s refusal to use his fire abilities, symbolizing his rejection of Endeavor’s legacy, and led him to depend solely on ice in combat. A pivotal U.A. Sports Festival clash with Izuku Midoriya rekindled memories of his mother’s resolve, compelling Shōto to harness his flames. This choice ignited his acceptance of his dual Quirk and a shift toward collaboration, though his reserved demeanor lingered. He later interned at Endeavor’s agency, prioritizing skill refinement over familial reconciliation, acknowledging his father’s heroism while preserving emotional detachment. During the OVA *Make It! Do-or-Die Survival Training*, Shōto joins a disaster rescue drill. Partnered with Fumikage Tokoyami, he halts falling debris with ice, avoiding flames to prevent carbon monoxide risks. As flooding escalates, he crafts an ice escape platform, then remains to freeze rising water, teaming with Katsuki Bakugo and Izuku Midoriya to engineer a geyser-propelled exit—a testament to his tactical flexibility and growing teamwork. Family strife resurges when League of Villains member Dabi unveils himself as Shōto’s presumed-dead brother Toya. Shaken by parallels between Toya’s vengeful descent and his own past resentment, Shōto vows to halt him, later offering Endeavor a hesitant olive branch, signaling fragile hope for shared healing. Post-graduation, he ascends to No. 2 pro hero, his fading scar reflecting incremental emotional recovery. His hero costume evolves from suppressing his fire side to integrating thermoregulatory tech, optimizing Quirk synergy. Later designs employ heat-resistant fabrics and efficiency-enhancing devices, embodying his journey toward equilibrium. Though childhood scars linger, Shōto forges a heroism defined by rescue ethics and combat integrity, transcending Endeavor’s shadow.
