Suggested by Anonymous Buggy may be a pretty good counter against the sword with how his body splits apart but that still won’t be enough to deal with Whitebeard. Whitebeard has his haki which is incredible in combat and so one good hit would end things. Buggy isn’t fast enough to keep up nor does he have the defense to withstand these kinds of blows. This is why he will be crushed here because Whitebeard is just completely out of his league. Whitebeard wins.
