One punch is a parody that is also in love with the genre its mocking. Its whole joke is now setting up the exact same type of story, running it 99% through the same gropes, them ending it in a whimsical way why still mapping up the epic battle, except some charectors keep getting punched in the balls.

In fact, the anime is such a big fan of the manga, it has also shifted to using static images as much as possible.
