Enji Todoroki The patriarch and Flame Hero: Endeavor. Driven by a crippling obsession to surpass All Might, he entered a "Quirk marriage" to breed a child strong enough to claim the Number One spot. This blind ambition led him to abuse his wife and children. After achieving his dream but realizing it felt hollow, Enji undergoes a painful, complex journey toward redemption. Rei Todoroki The matriarch of the family, possessing a powerful ice Quirk. Rei was bought into a loveless Quirk marriage with Enji, which quickly became an abusive nightmare. Driven to a severe mental breakdown by Endeavor's relentless pressure and cruelty, she infamously burned her youngest son Shoto with boiling water after being triggered by his resemblance to his father. Toya Todoroki (Dabi) The eldest son, whose tragic descent is the family’s darkest secret. Toya inherited a fire Quirk even hotter than Endeavor’s, but possessed his mother's fragile tolerance for heat. Desperate for his father’s approval, he pushed his body past its limits, leading to a catastrophic accident where he was presumed dead. Instead, he survived, became the scarred villain Dabi, and joined the League of Villains. Fuyumi Todoroki The eldest daughter and a dedicated elementary school teacher. Blessed with an ice Quirk, Fuyumi was largely spared from her father's brutal training regime, allowing her to take on a nurturing, maternal role within the household after her mother was hospitalized. She acts as the ultimate optimist and peacemaker of the family. Fuyumi constantly tries to organize family dinners and bridge the massive emotional divide between her bitter brothers and her transitioning father. Natsuo Todoroki The second youngest son and a busy college student studying medical welfare. Like his mother and sister, Natsuo possesses an ice Quirk and was deemed a "failure" by his father's standards, leading to severe emotional neglect. Unlike Fuyumi, Natsuo refuses to play nice or forgive. He openly and deeply resents Enji for the systemic abuse of the family and fiercely blames him for Toya’s presumed death, refusing to let his father off the hook for a lifetime of trauma. Shoto Todoroki The youngest son and a top student at U.A. High School. Shoto is the "perfect creation" Endeavor wanted, possessing the dual Quirk Half-Cold Half-Hot. Bearing a physical and emotional scar from his mother's breakdown, he initially rejected his fire side to spite his father. However, through his friendship with Deku, Shoto learns to embrace his full power as his own. He walks a heroic path, balancing his own growth while trying to help his family heal from their deeply scarred past.
