Luffy used KKG to beat Doflamingo. Kaido will take no less. The safe option was always a King Kong version of the Gatling.
Kaido is already bruised up and in his last form. Luffy has yet to tap into his potential. This entire thread is based on a mistranslation, when Luffy mentioned that the attacks ARE working.
The problem is, that this is most likely not his actual final form. Awakened dragon-devil form incoming, mate.
The visuals for awakened DF users are completely different to hybrid modes and that's definitely no coincidence.
Besides the fact that "heightened regen/resilience" is jackshit anyway compared to any other DF category's awakening
Someone like Lucci would be doomed if that would be all there is. Solely based on one's DF power he could not even compete with any ancient Zoan.
Shit + extra resilience = just more resilient shit..
Imo that will introduce us to the real WSC and it's the thing that will finally trump BM's all out performance later on.
And it is imo what will require Luffy to grow tremendously outside his DF capabilities.
Cause I also think advCoA KKG moves might be able to take care of hybrid Kaido, but awakening tho..
Imo the all-out Kaido matter won't be solved by higher punching power. I think he will enter the route of becoming a Roger-like haki God this Arc.
His DF imo will become more of supporting tool, that gives him the little extra, not staying his main muscle anymore.
