This internal conflict could be explored as he tries to find his place and purpose, perhaps leading him to form alliances with unexpected characters.
A third plotline might be that Izuku's non - human form gives him a unique connection to some ancient or otherworldly power. This power could be either a great boon or a terrible curse. As he tries to master this power, he has to face challenges not only from the villains but also from those who are jealous or afraid of his new - found abilities.
