And yet you didn't notice the series subverting many of the shonen formula tropes?

Foremost this episode being the assertion that a hero that hurts themselves overdoing it is completely worthless. Most shonen series will make such an action the pinnacle of heroics as some form of noble sacrifice. This one states unequivocally that if the hero themselves has to be rescued, they're better off simply not being in the field in the first place.

Kacchan is also one of those "rival" characters who comes off definitely more as a villain than he does as a hero, but overall, his motives seem pretty pure aside from wanting to be the center of attention. He hasn't been beating up Deku the way he used to ever since Deku saved him. I'd be pretty interested where it goes from here. How else can someone like him get ZERO rescue points, yell "DIE!" when he uses his powers, but not actively bully Deku? Something doesn't quite add up here.
