Izuku embodies timidity, reserve, and politeness, often reacting with exaggerated expressions to unusual circumstances. Enduring years of belittlement from Bakugo due to his lack of a Quirk, he initially appears as insecure, tearful, and non-expressive. Despite this, Izuku is caring and emotionally driven, always ready to aid or rescue those in peril, regardless of his own limitations. His actions stem from instinct rather than overthinking, often endangering himself to safeguard others.
