The core meaning of "My Hero Academia" revolves around the central question of "what makes a hero?". Creator Kōhei Horikoshi explores the idea that heroism is not defined by innate power or talent, but by unwavering determination, self-sacrifice, and the courage to act in the face of fear. The series posits that anyone, regardless of their background or abilities, can become a hero through hard work and a strong will to help others.
It delves into the nature of legacy and responsibility, symbolized by the passing of the torch from one generation to the next, most prominently through the One For All Quirk. The narrative also serves as a critique of a society that commercializes heroism and creates rigid structures, exploring the resulting societal cracks and the villains who emerge from them. Ultimately, the series champions the power of hope, friendship, and the idea that true strength lies not only in saving lives but also in inspiring the spirits of others.
