Synopsis

The seemingly ordinary and unimpressive Saitama has a rather unique hobby: being a hero. In order to pursue his childhood dream, he trained relentlessly for three years—and lost all of his hair in the process. Now, Saitama is incredibly powerful, so much so that no enemy is able to defeat him in battle. In fact, all it takes to defeat evildoers with just one punch has led to an unexpected problem—he is no longer able to enjoy the thrill of battling and has become quite bored. This all changes with the arrival of Genos, a 19-year-old cyborg, who wishes to be Saitama's discipleafter seeing what he is capable of. Genos proposes that the two join the Hero Association in order tobecome certified heroes that will be recognized for their positive contributions to society, andSaitama, shocked that no one knows who he is, quickly agrees. And thus begins the story of One PunchMan, an action-comedy that follows an eccentric individual who longs to fight strong enemies that canhopefully give him the excitement he once felt and just maybe, he'll become popular in the process.
