Best Wano chapter.
But I have some negatives: Art was rather spotty for chapter 1000. Characters look rather sketchy and undefine. And this isn't really a quality issue, the character models themselves look simplistic and rough.
That said, the composition on a lot of the panels was top notch. That giant spread of the Supernova vs the Emperors was spicy. That one picture encapsulates the timeskip saga up until now.
The Dawn
Luffy. The main man, planned to take out the Emperors to come closer to his ultimate dream of Pirate King. It started by defying Linlin, something no one on FMI dared to do.
His claim to take them out materialized further when he teamed up with Law. Quickly, the two became world wide partners, toppling Doflamingo and his underworld organization and destroying Caesar's manufacturings. This caught the attention of Kaido who still didn't take these brats seriously.
Luffy not only faces Kaido (and Linlin) for his dream, but to also liberate the home of the friends he's made. Momonosuke, Kin'emon, Hyogoro, and more. Luffy is the outsider who has garnered the trust and belief of people who were untrusting of the world beyond their borders.
His resolve to rescuing Wano strengthened when learning young children like Tama can't even eat whenever they want.
After a crushing defeat at the hands of Kaido, Luffy now stands against him, armed with the power he unlocked through the support of the Samurai that were once untrusting of outsiders.
He brings the world together in a way no one else can.
Shifting to Yamato and Ace's conversation, it's clear whatever Luffy and Roger said was monumental. So much so, most people would laugh at the proposition. Something even more ludicrous than becoming Pirate King. That can be covered in another day, but I can't help but think it's related to Luffy's ability to bring people together. Think about it, possibly the last big destination before Laugh Tale is a xenophobic, isolated nation, and you have someone with the charisma to touch people's hearts. In the real world, we're are all divided, just as how the One Piece world is divided into sections. Literally.
The Legendary Samurai
Zoro, Luffy's partner, is also there, and Oda's been building up his involvement in this battle even before the timeskip. When Zoro defeated zombie Ryuma, he retrieved Shusui and returned it to the country. Its absence was compared to a bad omen befalling the country, as Kaido and Orochi took on power and deteriorated the lands of its food, natural resources, and warriors.
Wano was a land of powerful and revered Samurai due to the legacy of Ryuma and its warriors upholding it, but we see now with all the Samurai either defeated or having to depend on Pirates. Zoro, whom's backstory is teased, stands as both a Strawhat Pirate and a bred, possibly born, Samurai of Wano fighting to save the country and reclaim the honor that's been lost.
True Pirates
Kid and Killer have had a journey that mirrored Luffy's and Zoro's. They both entered the New World with the intent of defeating the Emperors, and to do that they formed alliances.
Though it didn't go too well, and only hardship has befallen them; from imprisonment, betrayal, humiliation, misrepresentation (Caribou). Their reason for being here is retribution. Can they prove the world wrong and cement themselves as part of the big leagues? Whatever happens, Kid and Killer are going to contribute in the world's further destabilization. They do so for their own sake as next gen pirates.
The Mastermind
And lastly, Law was the originator of the whole operation vs Kaido. His first plan was to defeat Doflamingo and stop his distribution. He also made the first declaration that the era was shifting and that his generation will overtake the old that has grown stagnant.
All in all, this chapter didn't have much in the way of theories. Even the Yamato/Ace moment but re-acknowledged the importance of what Luffy and Roger said off-panel. But this chapter is the beginning of the narrative payoff for what's been building for almost a whole decade and more. That's what chapter 1000 represents, and it's a huge achievement. Yes, One Piece is not perfect. This chapter isn't perfect. But the level of investment and plotting Oda's crafted is nigh unrivaled in the Manga world.
Thank you, Oda.
P.S. Yamato is the final Strawhat.
