Article summary:
In the vast universe of Eiichiro Oda, one name frightens the World Government more than any other: Joy Boy. He is not merely a historical figure, but a promise of freedom. Discover who he was, his connection to the Void Century, and why Luffy is his rightful successor.
For years, this character remained a shadow, a legend inscribed on indestructible stones. But today, as we enter the final saga, the veil is lifting. Why is this character so central? What is his connection to the One Piece treasure? Let us delve into the secrets of the most important character in the story.

Joy Boy's return marks the beginning of the end for the World Government.
The First Joy Boy: A Figure from the Void Century
To understand who Joy Boy is, we must go back 800 years. Joy Boy was not an ordinary pirate; he was a central figure of the Ancient Kingdom. We know from the Poneglyphs that he made a promise to the mermaid princess of that era (the former Poseidon): to use one of the Ancient Weapons to bring the Fish-Men back to the surface.
He failed. His apology message is the first concrete evidence of his existence. But his failure did not mark the end of his dream. As the manga often says, a person's will never dies.
Is Luffy the Reincarnation of Joy Boy?
This is the question on every fan's lips. Since the Wano Kuni arc, the connection has become undeniable. When Luffy awakened his Devil Fruit, the giant elephant Zunesha spoke these words: "I hear the Drums of Liberation... Joy Boy has returned."

However, it is crucial to make a distinction. Luffy is not the literal reincarnation. He is the one who inherited Joy Boy's title through the awakening of Luffy Gear 5. The fruit he ate, the Hito Hito no Mi, Model Nika, carries the will of the "Warrior of Liberation" within it.
If you want to embody this freedom, our collection of Luffy figures traces the captain's entire evolution, from ordinary pirate to the new Emperor of the Sea.
Why Do Imu and the Government Fear Him?
If Joy Boy represents absolute freedom, his natural opposite is the rigid order imposed by Imu-sama. Joy Boy's return means the end of the Celestial Dragons' control.
The World Government has done everything to erase his name, even manipulating the history of names (such as the mystery of the D in One Piece). But they cannot extinguish a light passed down from generation to generation.
His clues are everywhere:
- The prophecy of Fish-Man Island (see our article on the island's prophecy).
- The giant Straw Hat preserved in Marie-Joie.
- The awakening of Mythical Zoan-type Devil Fruits.

Conclusion: The Dawn of a New Era
Joy Boy is far more than a character from the past. He is the symbol of rebellion. In 2026, as the manga draws to a close, we understand that the story of One Piece is that of an 800-year-old promise.
