Going back to the power lvl discussion, I doubt Pekoms and the other dude are the weakest, logic says otherwise..
Rockstar was a member of Shanks crew who seemed like one of the weakest links in the bunch, his bounty was 94 million, so if fighters worth 300 million are the weakest in BM's crew,the difference in power between both crews seems huge, considering that shanks was shown to have a relatively small amount of followers, I doubt that a random guy in BM's crew would be worth around 3 times more than a random guy from shanks' team and both would be yonkous..It may be the case,but it seems unlikely.
