Hey bum itchers, Shoto is the youngest son of Endeavor, the number one hero, and the product of a forced marriage between his father and a woman with ice powers. His dad raised him like a weapon, training him to be the perfect hero and pushing him to rely only on his fire side. Shoto's mother, who couldn't handle what was happening, poured boiling water on his face when he was a kid — leaving the scar over his left eye — and was sent away. Shoto grew up cold, distant, and determined to never use his fire quirk, just to spite his father. That changed when he was 15, after a fight with Izuku Midoriya at the sports festival, who showed him that his power was his own, not his dad's. He's spent the years since learning to be a person instead of a weapon — awkwardly, but genuinely.
