Izuku Midoriya is a normal quirkless boy, until he did a 3 year training regiment at the age of 12. The regiment? 100 pushups, 100 situps, 100 squats, and a 10 kilometer run for the next 3 years. He then became overwhelmingly strong. So strong in fact, that he found it boring. Watch his journey to become the world's greatest hero with ONE PUUUUUUUNCH!!!! (Art not mine)
