Kid made linlin cough up blood without haki
awakening made Luffy so strong haki isn’t necessary
Perhaps Kid hurt BM via his df power who probably ignore durability.
Fact is that Kaido didn´t even got a scratch via jumping from 10000km, you wanna say me a simple swing of Luffy did more then all his previous attacks where Kaido didn´t caugh up blood?
And you didn´t answer my question, why all off sudden Kaido got a cartoon character beat down, when a villian in Op ever got such thing?
