The most notable thing about Goku vs. Jiren fight, is that neither character was in their strongest form. They were down to 1% HP, and the fight was decided in their "base forms". I'm wondering if Oda is going to do the same with Luffy after Kaido comes back with awakening. Maybe after all the King Kong Guns, etc..., Luffy beats Kaido in his base form with some nice trickery.
Idea: what if Luffy grabs Kaido from Onigashima and crashes into Wano using a piledriver.
Kaido would be defeated in the same way he was introduced. Obviously Luffy would survive the fall because
I know it's likely Luffy wins with some Ultra Flaming spinning KKG or some shit like that, but I wouldn't rule a "basic win"
