Izuku is caring and emotional, never hesitating to help or rescue someone in danger, even if he knows that he might not be strong or otherwise qualified enough to do it. Often, he does this on instinct, taking a more careless approach than the usual overthinking he goes through and putting himself in peril in order to protect someone. All Might claims that this trait gives Izuku the most important natural and innate instinct to be a hero; the pure and genuine desire to help people.
