Saitama

A very casual and strong hero who got so strong just by 100 push 100 sit-ups 100 squads and a 10 kilometer run every day for 3 years to the point that he broke his litter and became bald he is even so strong he grew bored an lost all emotions fear, joy, anger, tension, fear, he feels none of those anymore which caused him to completely lose his ego and now his obsession is food from the sale and finding a strong opponent to regain his emotions. and he fights with nothing but his fists
