Joyboy was Binks, the first pirate and Davy Jones' brother, who went on a voyage, met Imu, and crashed Davy's wedding to Princess Lili, leading to Imu's corruption by the devil Mu after finding the Great Grimoire.
Imu does not act like a man who defeated Joyboy. Even centuries later, JB's haki is enough to make Imu tremble and clutch at his emotional support butterflies. If Imu did not defeat Joyboy outright, then how exactly did JB lose? How did his crew fail him?
What if the Void Century wasn’t simply the story of Joy Boy versus Imu, but the aftermath of a world-changing failure? The Harley describes three Worlds: two end in separation, while the Third promises that “they will surely meet.” Joy Boy failed. Roger arrived “too early.” Rocks believed he could overthrow Imu, yet was also too early. Meanwhile, Lily preserved the truth, the Ancient Weapons survived, Poseidon was born eight centuries later, and Loki now carries the power of the ancient Warrior God who once fought the Sun God. What if these aren’t separate mysteries? What if history keeps recreating the same failed configuration and Luffy’s generation is the first to bring its missing pieces together?
