Kaido's fall at Onigashima marks the beginning of something far more terrifying. For over three decades, Caesar—Kaido's forgotten elder brother and wielder of the Zoan Fish Fruit Model: KunPeng—lay dormant beneath the cursed island. Once revered by Big Mom and dreaded by a young Whitebeard, he awakens to a world transformed. Caesar views his brother's defeat as nothing more than pathetic weakness. The Sun God Nika? A mere footnote. Admiral Ryokugyu? Beneath his notice. From Onigashima's burning core, a world-shattering roar tears through reality. A monstrous aura fractures the heavens. Shockwaves shred the very fabric of the sky. "KAIDO! Foolish little brother! At last, you fall!" "Thirty years of slumber ends now. I, Caesar, shall engulf this tedious world in chaos! Borororo!" [AU: Caesar and Linlin share four biological sons—Perospero, Katakuri, Daifuku, and Oven. The remaining children were adopted by Linlin, standing ten years younger than their eldest siblings]
