More I see about Kaido crew, so more I can tell that the Minks would have it even harder.
Imagine Kaido sending two flyers like Pageone and Ulti+many headliners to backup Jack, for sure the Minks would get overwhelmed.
It show that Kaido crew is really tough and large, if one squad of him can give a whole nation like the Minks very trouble.
And it seems like he have over 10Squads...
King squad
Queen squad
Jack squad
Who´sWho squad
Sasaki squad
Black Marie squad
Ulti and Pageone squad(I think both where in same crew)
xDrake squad
Apoo squad
Hawkins squad
Overall you can see how balanced and well Kaido crew are, each squad is powerful and strong, alone these make his crew looking very good. Outside of the Yonkous,RA and Navy no one could even fight him back, I can understand why Doflamingo fear Kaido so much, Kaido himself isn´t even need to take out other countries.
