Recently news of Big Mom and Kaidou’s defeats spread all across the world and the three responsible for it Luffy, Eustass Kid and Trafalgar Law, were issued huge bounties as a result: 3,000,000,000 Berries each! The 3 captains were equal and only Luffy had the Emperor title? Why was that?
I saw a theory according to which their bounty was based on the total bounty of Big Mom and Kaido, which is roughly around 9 Billion Berries and split between the three of them. Which makes sense for me, now the next mystery would be why only Luffy got to have the title of Yonko.
Is it because Luffy defeated Kaido alone? It might be. Then an idea came in mind, it also might be because of what it’s happening outside Wano.
I remembered this cover from Chapter 875.
This only shows the Straw Hat Grand Fleet has been wreaking havoc all over the Grand Line spreading the Straw Hats’ influence and the Marines can’t control it. This also aligns with how Buggy must’ve been crowned as Emperor, due to his influence and he must’ve amassed a fleet with big names that the Marines can’t control.
