Life gets pretty boring when you can beat the snot out of any villain with just one punch.
Nothing about Saitama passes the eyeball test when it comes to superheroes, from his lifeless expression to his bald head to his unimpressive physique. However, this average-looking guy has a not-so-average problem—he just can’t seem to find an opponent strong enough to take on!
Despite just finishing a martial arts tournament and immediately dealing with the Monster Association invasion, Saitama is still so incredibly strong that he feels empty inside. King lectures him on how to live like a hero, but it doesn’t help. Meanwhile, servants of the Monster Association close in on Speed-o’-Sound Sonic!
