What's kinda funny some people from other forums I lounge about in, say that Big Mam is the weakest link instead Kaidou. Quite frankly I think top dogs are Shanks (no doubt #1), Kaidou, then Big Mam.
True BB has strong crew members with intimidating atmospheres and ruler of the world ego. I can't help but think for some little reason that he is not all that strong and hyped up from what people may think. I'm not ranking him just yet, I'll await to see what more events shall unfold in the future.
