At the age of 4 a certain doctor told him to give up his dreams of being a hero. He told him, that it's likely that his quirk won't ever manifest. But Izuku knew that he had a quirk, but no one wanted to believe him. A new, never before seen quirk, had appeared in the boy. "Hah, I bet that he only pretends he has a quirk" "Show us your quirk, oh wait. You can't haha." "He is just being delusional. He is fooling us because he doesn't want us to know that he is a quirkless loser!" "Don't even think about going to U.A. DEKU! Or else I will kill you! He will prove them wrong.
