Saitama always wanted to be a hero and he trained so hard that he is really powerful so much so that he can literally explode monsters into pieces by a single punch. For people who have no idea about this anime, Earth has lots of heroes who work for the hero organization.
It is fun to see Saitama disintegrate these monsters with just a single punch.
Some can even destroy entire cities and even planets. The anime has lots of monsters who seem very strong. This is because it is one of the best anime that has come out recently. ‘One Punch Man’ is in various lists of anime across the internet.
