Izuku was misdiagnosed as quirkless as his family hated him. Everyday the talk down on him as if he's trash. One day Izuku overheard that he is not even their real son as that he's someone else's and they only kept him for ransom which they had never paid. Soon Izuku ran away as he look for his real family as one day he saw that his hair was dyed green as he saw from that rain that he now has black hair like his father. As the day progressed Izuku unlocked his quirk which his real father had which is fire (not Endeavor) which was stronger then Endeavor himself. One day Izuku did find his real biological dad (Hisashi) and they both became the best of father and son as he introduced his real mother (chisato).
