So... how about... a mob psycho x BNHA crossover where izuku is a powerful esper and he knows it so he hides it by not using his power. Inko registers him as quirkless and he is bullied daily. one for all would basically be useless because izuku's esper powers overpower the quirk... he gets in to UA and decides that he's finally (after 15 years of suppression) gonna use his abilities but then he kinda loses control and almost destroys the earth but manages to contain it and decides never again. The problem is that nedzu saw all of that and now izuku is going through quirk and emotional therapy!!!!!!!!!!!!!! He's not gonna show a lot of emotion nor is he gonna try to because it's really dangerous to him, if his emotion is strong it will cause destruction. (He wants to feel it though.)
