So wait a hardening punch cant be stronger just because its sabo s signature attack?
From what manga showed is fire fist cant damage base gorosei
Fire fist cant launch them across the island
Kuma s punch has more ap and dc
Next you would say fire fist is stronger than base luffy acoc punch bcs its sabo s signature attack
It's not just a random fire attack, it's the fire fist which had been used by Ace and Sabo. It has high fire power and lethality. It is also one of Ace' strongest fire techniques even though it's a signature move.
You remember when Sabo used a Ryuo technique to split the arena in half? His fire fist tore through the entire arena, immediately vaporized all water and the fire punch went through the underground. Even then, Sabo's basic hardening techniques yeeted Burgess away through city blocks as well. Again, DR Sabo is weaker than current Sabo.
Bruh, Saturn flew through some buildings. This is visually no different to Sabo yeeting Burgess away.
Kuma has a physical advantage due to his race but Sabo is not that far weaker than Kuma. He's his student... Kuma taught him all those techniques and power.
You hear yourself? 1.) It's ACoC, 2.) Kuma's been using the same Haki which Sabo also demonstrated several times.
Plus, only because it's ACoC doesn't mean it hits harder than non ACoC attacks. Does base ACoC Yamato hit harder than rooftop Zoro's Shishisonson?
