This attack by the strawhats is fight one after another: chopper, franky, brook, usopp, robin, nami, sanji, zoro and finally luffy.
The three last ones are the order, as we would order them by strenght. Does this mean anything or is this ranking just coincidence? As I do not believe that Oda has any coincidence in his great work… May he rank the strawhats this way in their fighting power? I do agree with the three last ones, but I think the other ones show us something else: Chopper was the first one after Sanji, Zoro and Luffy, who attacked Kumabot, what I think is awesome! Brook seems to like falling from the sky, he always falls somehow from the sky. He now uses his destiny to attack, great! Nami is pure pain. As her attack went through Kuma, I think she caused the malfunction.
Edit: Zoro feels the fatigue and pain, Luffy feels. Did Kuma told him anything about that this bubble is just a onetime thing, or could zoro have inhaled luffys fatigue and pain literally. like now and forever. damn, that would be incredible...but not unbelieveable....Oda is such a..
