The end of the Wano arc signified quite a massive change for One Piece. After the most prominent pirates from the Worst Generation joined forces to defeat the Emperors Kaido and Big Mom, Luffy was promoted to the rank of Emperor as well, but was thought of as being on the same level as Trafalgar Law and Eustass Kid, which can be seen through their matching bounty of 3 Billion Berries and their equal number of Poneglyph rubbings.
