I disagree.
Is jet pistol from G2 Luffy with advanced conqueror's, stronger than a full power supreme kong gum from rooftop Luffy? I don't think so. A low end attack from a stronger mode need not be stronger than the strongest move with full effort from a weaker mode. In fact, it tends to not be the case.
KoH Dragon Damnation >= Togen totsuka > Asura > anything else Zoro used in the arc
By the way, what is Ultra Gari? Ultra tiger? That didn't land on King IIRC, he dodged it
Yeah, check it out.
Just to add on. Scabbards went on offense against Kaido, did their own version of togen toksuka, had Kaido down, Kiku's hand got chopped and Kaido started his beatdown. Before BM vs Marco was finished.
