Can Somebody explain one Punch Man to me?

[Scowling Dragon]

Its not even a gag as just a easily recurring thing in Fighting Mangas.

"Dragonball did it only when it was a gag Manga!"

I don't get how thats a repudiation of my point. One Punch man isn't really doing anything original even as a Gag Manga. Outside of novelty factor I find nothing to my liking.

Its not even a dragonball thing....Heck I spent time to find something to help me stress my point:

Like is because most fights in other fighting shonen don't end with one punch somehow that is all it takes to make this gag all original or something?
