I still can’t cope that a no named guy is as strong as the great Rocks captain of the titanic rocks pirates, father of BB, challenger of Imu, rival of Roger
WB/Roger - Shanks/Mihawk are all extremely important and established characters
Harald appeared out of the blue
Even Oden was more important lore wise and he has the courtesy of dying before Kaido reached his peak and he still wasnt as strong as WB/Roger etc
Harald isn’t that out of the blue, we were told pre time skip that the Giant warrior pirates were the greatest pirates on the sea 100 years ago.
Oda realized that this statement didn’t make any sense after making Dory and Broggy so weak and making the One piece verse so much stronger than it was by Little garden. so Oda side stepped his own statement to say that Giants in general ruled the sea since all Giants were thieves and pirates, not just the Dory and Broggy pirates, the entire country was pirates basically.
So Oda is covering his tracks. Giants can’t be considered the top pirates of several centuries if their top man in each century isn’t pirate king tier
