Chapter 1027: The Battle for World Strongest Creature
The chapter spans 500 pages and consists purely of Luffy vs Kaidou. Each clash breaks the sky and the sea, culminating in the OP planet's atmosphere and also The Red Line completely destroyed, exposing All Blue, Uranus and Laugh Tale. Every 3 pages everyone commenting, "Holy Shit!" And every 10 pages there's experts like BM, Yamato, King, Zoro, Law, Kidd analyzing the details of Luffy vs Kaidou powerscaling. Every 200 pages, BB-Shanks-Imu use their CoC radar to sense the fight, smile and tell their underlings about how the tale of Lost History, Will of D, Voice of All Things, Inherited Will etc will be fulfilled beginning from now.
In the final clash, Luffy finally invents King's Star Ocean Gauntlet technique which destroys Kaidou's strongest attack ever and also shatters Kaidou's haki permanently, taking the WSC status from him. Kaidou, in no more possession of haki, tries to destroy Wano Capital by the use of Dragon Form and prepare the final Boro Breath which is stronger than Hakai, but before he can release it, Luffy gives a signal to Zoro and the Pirate Hunter fulfills ZKK by using new Thunder God Form Takemikazuchi, the second spirit after Asura.
While Luffy steps to the top of Onigashima skull, saying to an seemingly unseen person. "i know you are waiting here, laughing at all of us. Now come down here, and let's settle this."
Responding to that, a dimensional gate opens, and the Lurking Legend appears to destroy the world, making BB-Shanks-Imu (at each's headquarters) pale and shivers in fear. They all say "Holy Shit."
Because he is here to bring hellscape to the realm. He is Tonjit.
