Izuku was born with a quirk. A really strong one at that. Izuku rarely shows his quirk to others in fear he'll hurt someone. Izuku trains daily, both body and mind. He trains so he can have better control of his quirk. Izuku realized early on that his powers are fueled by his emotions. He found this out after getting frustrated in a forest and completely deforested the forest on accident. Izuku at the age of 15 had perfect control over his quirk but he seemed emotionless to most. Also, using his powers he can heal others.All Rights Reserved
