Wdym? Every title is rooted in the majority’s perception, whether their opinions matter or not. I already explained that Roger’s title was the result of everything he accomplished: his actions, his reputation, and his very existence. Finding a mythical island was just the icing on the cake. Nobody would care if some random pirate claimed they left treasure on a mythical island. What made it legendary was Roger himself. Even Mihawk, of all people, showed interest in witnessing Roger’s final words. The world was stirred up because it was Roger’s treasure. His name carried the weight of the One Piece treasure, not the other way around.
Should I instead start listing all the moments that put Roger on a pedestal strength-wise? The legends themselves such as Kaido , Big Mom, Garp, Shiki, they all acknowledged him. Whitebeard’s hype came from being Roger’s equal, not the other way around. Saying the Pirate King title isn’t strength-related, especially in Roger’s case, is ridiculous. “Wealth, fame, power” — a man who achieved everything.
