Can Somebody explain one Punch Man to me?

[Kato]

Yes He Does. Thats my point. Even in Dragonball, the defining Shonen show, the exact same thing would happen to goku:

"Mwahahaha, Im big giant monster with superpowers talkin **** about you small boy"
"ONE PUNCH VICTORY!"

You don't GET to do a sigh at the camera if your doing what every other shonnen does anyway.

I'm not sure what episodes of DB you've seen but this is hardly ever the case, so....
