Saitama

Saitama was an unemployed man who dreamed of becoming a hero that could defeat villains with a single punch. After saving a child from a crab monster, he dedicated himself to intense training: one hundred push-ups, sit-ups, squats, and a 10 kilometer run every day for three years without air conditioning. This regimen caused him to become bald and granted him extraordinary strength, but left him bored as no opponent could challenge him. He hopes for a worthy adversary.
