One Piece fans have spent decades building an elaborate villain profile for Imu. The shadow ruler of the World Government. The immortal enemy of Joy Boy. The ultimate force of oppression standing against freedom itself.
Everything we thought we knew just collapsed.
The latest chapters of Eiichiro Oda’s masterwork have dropped a revelation so massive it reframes the entire Final Saga: Imu and Joy Boy were once friends — allies who shared genuine moments before the Void Century war tore them apart. This isn’t just a plot twist. It’s the emotional earthquake that could redefine everything about the One Piece endgame.
The Revelation That Broke Every Fan Theory
For years, the prevailing theory was straightforward: Imu represented the tyranny that Joy Boy fought against. Good versus evil. Freedom versus control. The Twenty Kings who formed the World Government were the villains, and Joy Boy was the hero who opposed them.
Then Oda pulled the rug out from under us.
Recent Elbaph arc flashbacks have revealed something nobody saw coming — moments of genuine connection between Imu and Joy Boy before the Great War. Friendly interactions. Shared experiences. A bond that existed before everything shattered into the 200-year blank that fans call the Void Century.
This changes the entire conflict from a simple good-versus-evil narrative into a deeply personal tragedy. The war that shaped the One Piece world wasn’t just about ideology — it was about a friendship that became the most devastating betrayal in history.
Why Oda Built This Reveal With Surgical Precision
Oda doesn’t drop information randomly. Every detail in One Piece is planted chapters — sometimes hundreds of chapters — before it matters. The Imu-Joy Boy connection has been foreshadowed in ways we’re only now connecting:
1. The Nerona Imu Full Name Matters
The revelation of Imu’s full name — Nerona Imu — wasn’t just flavor text. In One Piece, names carry weight. “Nerona” has linguistic ties to concepts of sovereignty and ancient authority that predate the World Government itself. This suggests Imu wasn’t always the hidden ruler — they may have been part of the same civilization as Joy Boy.
2. Elbaph as the Convergence Point
Elbaph (Elbaf) has been built up as the land of giants — a place connected to both Joy Boy’s ancient kingdom and the Sun God Nika. Imu’s arrival at this location isn’t random. It’s a return to ground zero. The place where the friendship ended and the war began.
3. The Ancient Kingdom’s True Nature
If Imu and Joy Boy were allies, the Ancient Kingdom that Joy Boy led may have included Imu as part of its leadership. The schism between them could have been what fractured the kingdom from within — making the Twenty Kings’ rise possible because the original alliance was already broken.
The Betrayal Theory: What Happened Between Them?
Here’s where things get fascinating. Several competing theories are gaining traction among the community about what drove Imu and Joy Boy apart:
Theory 1: The Immortality Divide
What if Imu discovered a path to immortality that Joy Boy fundamentally opposed? The Ancient Kingdom possessed technology far beyond anything in the current era. Perhaps the creation of the Eternal Youth treatment (which Imu is rumored to have undergone) was the philosophical breaking point between them — Joy Boy choosing mortality and freedom, Imu choosing eternal control.
Theory 2: The Poneglyph Split
The Poneglyphs were Joy Boy’s way of preserving history. Imu’s World Government spent 800 years trying to destroy them. This isn’t just political opposition — it’s the behavior of someone who has a deeply personal reason to erase a specific version of history. What if Imu wants the Poneglyphs destroyed because they tell a story about a friendship Imu wants the world to forget?
Theory 3: The Third Party Manipulation
What if neither Imu nor Joy Boy was the original villain? Some fans theorize that a third force — perhaps connected to the Moon civilization or the Ancient Kingdom’s own technological hubris — manipulated the split between them, turning allies into enemies and setting up the Void Century war.
How This Connects to Luffy’s Journey
Here’s the parallel that makes this reveal absolutely devastating for Luffy’s story: Luffy is the inheritor of Joy Boy’s will. If Joy Boy and Imu were once friends, then Luffy’s ultimate confrontation with Imu isn’t just about defeating a villain — it’s about finishing something Joy Boy couldn’t.
Could Luffy be the one to finally resolve the conflict that Joy Boy couldn’t? Not by destroying Imu, but by breaking the cycle that has consumed the world for 800 years? The Sun God Nika has always been about bringing joy and freedom — perhaps the final victory isn’t a battle at all, but a reconciliation that Joy Boy never got the chance to achieve.
Think about how perfectly this mirrors Luffy’s entire character. He doesn’t defeat his enemies — he converts them. From Crocodile to Doflamingo to Katakuri, Luffy’s greatest victories come when he changes people’s hearts, not when he punches them. If Imu’s story is ultimately about a broken friendship, Luffy is the one character in the entire series uniquely equipped to heal it.
The Ancient Weapons Connection
The three Ancient Weapons — Pluton, Poseidon, and Uranus — were supposedly created during the Void Century. If Imu and Joy Boy were allies, they may have worked together on these weapons before the split. This raises terrifying questions:
- Did Imu have access to these weapons before the war? If so, the World Government’s hidden power might be far greater than anyone realizes.
- Was the split triggered by a disagreement over the weapons? Joy Boy may have wanted to use them for protection while Imu saw them as tools of domination.
- Is there a fourth weapon? Oda has been mysterious about whether there are more Ancient Weapons than the three we know about.
What This Means for the Final Saga
The Elbaph arc was always going to be crucial — it’s where Luffy claims the Road Poneglyph and moves closer to Laugh Tale. But if Oda is using it to reveal the Imu-Joy Boy backstory, then Elbaph is also the narrative bridge to the final confrontation.
The post-Elbaph arc has been teased as the biggest since Marineford. Now we understand why. It’s not just about battles — it’s about the resolution of a personal tragedy that’s been festering for 800 years. Every Straw Hat crew member’s dream, every ally they’ve made, every enemy they’ve faced is leading toward this moment.
Why This Is Oda’s Most Brilliant Move Yet
One Piece has always been about inherited will — the idea that dreams and ideals pass from one generation to the next. By making the central conflict about a broken friendship rather than a simple war, Oda has elevated the entire story. The One Piece isn’t just about finding treasure. It’s about healing a wound that’s been bleeding for eight centuries.
And Luffy, with his impossible ability to connect with anyone, might be the only person who can finally close that chapter.
What do you think happened between Imu and Joy Boy? Was their friendship real, or is Oda setting up an even bigger twist? Drop your theories in the comments — because if there’s one thing One Piece has taught us, it’s that the truth is always stranger than we expect.
