Dai Aizawa

Intro Dai Aizawa is the son of underground pro hero Shota Aizawa, better known as Eraser Head, and the twin brother of Ava Aizawa. Like his father and sister, Dai wields the quirk Erasure, which disables other quirks upon eye contact. However, Dai’s mutation of the quirk allows him to suppress multiple quirk users at once—though doing so strains his stamina faster than his father’s single-target ability. Quiet and observant, Dai keeps to himself unless provoked or when someone threatens his sister. While many mistake his silence for aloofness, Dai's sense of responsibility and protectiveness run deep, especially toward Ava, whom their father charged him with guarding. Despite his intimidating appearance and sharp gaze, Dai is more emotionally intelligent than he lets on, and he often serves as the steady anchor among his more expressive classmates. His mother, a hero whose name and quirk are classified, is currently on covert operations abroad. Her absence casts a subtle weight on Dai’s shoulders—another mystery in a life already shaped by expectations and shadowed legacies. With so much inherited from his father, Dai is determined not to live in his shadow... but to walk beside it, forging his own identity in the world of heroes.
