One Punch Man
 

Saitama is an unemployed, depressed young man with no deep purpose in his life. One day he meets a crab man who is looking for a young boy "with a chin slit like an ass" in his words. Saitama ends up meeting this young boy and decides to save him from the crab man, whom he manages to beat with difficulty. From then on, Saitama decides to become a superhero and trains for three years very seriously: 100 push-ups, 100 squats, 100 abs and 10 km of running every day and there are no heating or air conditioning conditions. . At the end of his training "so intense that he loses his hair", he notices that he has become so strong that he now manages to beat all his opponents with one punch. His inordinate strength is a source of problems for him, since he cannot find opponents to his size and is bored in his job as a hero because the fights no longer give him any sensation or adrenaline ... Although he has put an end to a number of threats, each more dangerous than the next, no one seems to notice Saitama's incredible ability, except for his friend and disciple Genos, a young man turned cyborg.
