So, I've been thinking about good gold buggy... he is in quite a pinch in between crocodile and mihawk, both people that can defeat him easily for the most part. We know he recently offered his organization to crocodile to form the cross guild. Presumably this organization is made up of the combination of resources of buggy, mihawk and crocodile. Buggy's cross guild is made up of former ID prisoners along with whoever else he picked up on the way. Overall a pretty strong militia. Then you have mihawk that brings his own ass to the table. In practice he is probably the yonko of the organization. And then crocodile... I am thinking he probably brings to the party smarts and perhaps some executive types?
But buggy is still in a precarious situation. In the end neither crocodile nor mihawk care about him. Though him winning over mihawk is not impossible IMO. Buggy is a god damn idiot but when required he can make friends and throw a party. But still, even outside of that the plot in the long run actually has a more or less favorable scenario for him. Mihawk is zoro's ultimate target and odds are that mihawk will die to zoro at the end. So that's one enemy down for buggy. Which leaves the much less threatening crocodile. Crocodile is not someone luffy has any love for so he might be defeated again by him. Or perhaps a crewmember.. In any case if crocodile is taken out then that leaves buggy as the sole head, officially and in practice, of the cross guild. A presumably more powerful organization than he had. It's mostly a matter of how the plot solves the crocodile issue.
