Fuck the Calamities and F6, they can't do anything other than holding off the invading forces. Kaido himself has to do everything again, especially Kaido has been fighting the multiple top fighters of the invading force in the roof and whoops them. The beast pirates without Kaido is like a haki-less Luffy. Kaido carried his crew so much. If only he got a crew like Shanks he will already be the PK.
