If Buggy ends up saving or protecting Vivi at any point in this series I will be so happy.
He really does have the same hair. It would be amazing if Buggy was connected to the Ancient History that heavily. We still don't know how he joined the Roger Pirates... Buggy could be conencted to so much.
Just Buggy protecting the Straw Hats would destroy me, though. Honestly. I would fall out of my chair and weep if Buggy protected the Straw Hats in a crucial moment.
And I think he will. No one loved Roger more than Buggy and Shanks, to me. Roger's death destroyed Buggy. Once Buggy realizes Luffy really IS the man Roger was looking for... Buggy will do something amazing, to help Luffy. I believe that.
Buggy's treasure was never gold, or the One Piece. It was the memories he made on Roger's crew, as Roger's nakama. Once Buggy realizes this, he'll be free, and become a completely different clown.
