One Piece has always thrived on its ability to turn everything you thought you knew upside down. Just when you thought you had the Final Saga figured out, Eiichiro Oda drops a flashback that completely rewrites the foundation of the entire story. The latest Elbaph arc reveal — that Joy Boy and Imu were once allies — isn’t just a plot twist. It’s the kind of revelation that makes you want to go back and reread every single chapter from the beginning.
This changes everything. The centuries-old conflict between the forces of freedom and the shadowy World Government isn’t just a clash of ideologies. It’s personal. It’s a story of broken trust between two people who once stood side by side. And understanding how that relationship shattered might be the key to predicting where One Piece is heading.
The Elbaph Flashback That Rewrote One Piece History
The newest flashback sequence in the Elbaph arc has fans absolutely reeling. For years, Joy Boy and Imu have been portrayed as the ultimate opposites — Joy Boy as the champion of liberation and Imu as the faceless tyrant ruling from the Empty Throne. The narrative seemed straightforward: a war between good and evil, freedom and control.
But the latest panels reveal something far more complex. Before the Void Century erupted into its devastating war, Joy Boy and Imu shared genuine, friendly moments. They weren’t always enemies. At some point, they were close enough that their eventual betrayal cuts infinitely deeper than a simple ideological disagreement ever could.
Think about what this means. Oda didn’t just give us another villain backstory — he gave us a tragedy. The Void Century wasn’t merely a political conflict. It was a personal fallout between two people who once trusted each other, escalated into a war that reshaped the entire world and erased centuries of history.
What This Means for Joy Boy’s True Identity
If Joy Boy and Imu were allies, it raises questions that have massive implications for the Final Saga:
- Were they co-rulers? The most popular theory is that Joy Boy and Imu once governed the Ancient Kingdom together. Imu may have been Joy Boy’s closest confidant before choosing a different path. This would explain why Imu has such intimate knowledge of the Ancient Kingdom’s secrets and why the World Government seems so terrified of the truth resurfacing.
- What caused the betrayal? This is the million-dollar question. Did Imu become corrupted by the power of the Eternal Pose? Was there a fundamental disagreement about the use of the Ancient Weapons? Or did Joy Boy discover something so dangerous about Imu’s true nature that their alliance became impossible to maintain?
- Is Luff destined to repeat Joy Boy’s mistakes? If Luffy truly is Joy Boy’s reincarnation — as the Gear 5 awakening and the Drums of Liberation strongly suggest — then understanding Joy Boy’s relationship with Imu becomes critical. The pattern of alliance-turned-enemy could repeat unless Luffy learns from history.
Five Theories About the Joy Boy-Imu Rift That Could Define the Final Saga
1. The Ancient Weapons Disagreement
The most compelling theory suggests that Joy Boy and Imu’s split centered on what to do with the Ancient Weapons — Pluton, Poseidon, and Uranus. Joy Boy may have believed they should be sealed away, while Imu wanted to weaponize them for absolute control. This would explain why the World Government has spent 800 years hunting for these weapons.
2. Imu Was Never Human
Some fans believe Imu is not a person at all but rather an entity — possibly connected to the mysterious “Devil” referenced in Devil Fruit lore. If Imu was never truly human, the betrayal becomes even darker: Joy Boy may have been allied with something inhuman that slowly revealed its true, terrifying nature. This connects beautifully to the three God-level Devil Fruits theory that’s been building throughout the Elbaph arc.
3. The “One Piece” Itself Is Their Shared Promise
Here’s where it gets wild: what if the One Piece treasure on Laugh Tale isn’t just a hoard of wealth but something Joy Boy and Imu created together? A promise, a message, or even a weapon they designed as allies before their falling out. Gol D. Roger’s famous line — “We are too early” — takes on a whole new meaning if the treasure involves reconciling their broken bond.
4. The Void Century Was a Civil War Within the Ancient Kingdom
This theory reframes the entire Void Century conflict. Rather than an external invasion, it may have been an internal civil war — Imu’s faction versus Joy Boy’s faction. This would explain why the World Government was so thorough in erasing history. The Twenty Kings who founded it weren’t conquerors from outside; they were the victorious side of a devastating internal conflict.
5. Luffy’s Gear 5 Is the Key to Healing the Original Wound
The most emotionally resonant theory suggests that Luffy’s awakening as Joy Boy isn’t just about power — it’s about finishing what Joy Boy started. If the original conflict was a personal betrayal, then defeating Imu might not just mean winning a battle. It might mean something far more complex: proving that Joy Boy’s vision of freedom was right all along, and healing a wound that’s festered for 800 years.

How This Connects to the Current Esperia Storyline
The Elbaph flashback isn’t isolated from the present narrative. The World Government’s arrival in the Esperia Kingdom — and their ruthless destruction of it — mirrors exactly what they did 800 years ago. The pattern is clear: any kingdom or people that get too close to the truth about the Void Century face the same fate.
Brook’s connection to the Esperia Kingdom, as explored in our Chapter 1185 theory article, adds another layer. If Esperia held knowledge about the Joy Boy-Imu alliance, its destruction was not random — it was calculated. The World Government is systematically eliminating any thread that could unravel their version of history.
What This Means for One Piece’s Ending
Here’s the bold prediction: One Piece won’t end with Luffy simply punching Imu into the ground. The finale will require something deeper — exposing the truth of the Void Century, revealing what happened between Joy Boy and Imu, and offering the world an honest history for the first time in 800 years.
The final battle won’t just be about power. It’ll be about truth. And if the Joy Boy-Imu alliance reveal is any indication, that truth is going to be far more complicated — and far more emotional — than anyone expected.
The World Government’s worst nightmare isn’t a pirate king with the power of a sun god. It’s a world that finally learns what really happened 800 years ago. Because once people know that the “gods” of the Empty Throne were once friends with the man they now call a demon… the entire foundation of their rule crumbles.
What Do You Think?
Do you believe Joy Boy and Imu were co-rulers of the Ancient Kingdom? What do you think caused their betrayal? And most importantly — will Luffy be able to break the cycle, or is he doomed to repeat Joy Boy’s tragedy?
Drop your theories in the comments. The Void Century’s secrets are finally coming to light, and every fan has a piece of the puzzle.
