One Piece fans have spent over eight years theorizing about Nerona Imu, the shadow ruler of the World Government. But when Eiichiro Oda finally gave us Imu’s full reveal in the Elbaph arc, it wasn’t just a face we were waiting for. It was a weapon.
The Sword of God — a blade introduced alongside Imu’s devastating descent into Elbaph — might be the single most consequential detail Oda has dropped in the Final Saga. And if you look closely at everything we’ve learned about Imu’s powers, the Void Century, and the ancient weapons, a terrifying picture starts to emerge. This isn’t just a sword. It’s the key to how the world was broken — and how it might finally be set free.
The Sword of God: What We Know So Far
During the climactic moments of the Elbaph arc, Imu appeared wielding a weapon that the narrative itself called the “Sword of God.” This wasn’t casual naming. In One Piece, when Oda gives something a name like that, it carries weight. The sword was introduced in the context of Imu’s Devil Fruit abilities, suggesting the blade is either a manifestation of those powers or intrinsically connected to whatever Devil Fruit Imu consumed.
What makes this especially chilling is the timing. Imu arrived in Elbaph — the legendary land of the giants, a kingdom that has stood for millennia and holds some of the deepest secrets of the Void Century. The sword didn’t just appear in any arc. It appeared here, at the crossroads of the Ancient Kingdom’s history and the World Government’s darkest lies.
Imu’s Devil Fruit: The Akuma no Mi That Started It All
Here’s where things get wild. Recent chapters have heavily implied that Imu’s Devil Fruit might be the original Devil Fruit — the Akuma no Mi itself. The name “Akuma” literally means “demon” or “devil.” In a series that has spent 1,100+ chapters building toward this reveal, the possibility that Imu wields the first and most powerful Devil Fruit is staggering.
Think about what we’ve seen Imu do: command ancient weapons like Uranus, wield destructive powers that can obliterate entire islands in seconds, and maintain dominion over the world for over 800 years. If Imu’s Devil Fruit is the primordial source of all Devil Fruit power, it would explain why no other ability user — not even Luffy with Gear 5 — has been able to match the sheer scale of Imu’s authority.
The Sword of God might be the physical manifestation of this power. In many mythological traditions, the first weapon wielded by a godlike figure isn’t forged — it’s born from their power. Oda has a history of pulling from these archetypes, and the Sword of God fits that pattern perfectly.
How the Sword of God Connects to the Void Century
The Elbaph arc has been dripping with Void Century lore, and the Sword of God sits right at the center of it. Here’s the theory that’s been gaining serious traction among fans:
- The Sword of God was used to destroy the Ancient Kingdom. The 20-year gap between the Ancient Kingdom’s golden age and its sudden, total annihilation suggests a weapon of unimaginable power. The Sword of God fits this perfectly — it’s not just a blade; it’s a world-ending instrument.
- The “God” in Sword of God refers to the Ancient Kingdom’s sun god. Oda has established Sun God Nika as the symbol of liberation and freedom. If Imu’s sword claims the title of “God,” it represents the usurpation of divine power — the World Government stealing and corrupting what belonged to the Ancient Kingdom.
- The blade is connected to Mother Flame and the ancient weapon Uranus. Imu has demonstrated the ability to command destruction on a planetary scale. The Sword of God may be the focusing tool that channels Uranus’s power, making it a weapon that can be wielded in direct combat, not just as a distant threat.
Why Luffy’s Gear 5 Is the Counter to the Sword of God
This is where the final battle starts to take shape. If the Sword of God represents absolute tyranny, oppression, and the corruption of divine power, then Sun God Nika — Luffy’s awakened Devil Fruit — is its natural opposite. Nika is the Warrior of Liberation. The Sun God who brings laughter, freedom, and the breaking of chains.
The symbolism is almost too perfect: the Sword of God (oppression, destruction, stolen divinity) versus the Sun God (liberation, joy, reclaimed power). Oda has been building toward this clash since the very first chapter. Every Straw Hat victory, every defeated tyrant, every freed island has been a stepping stone to this final confrontation.
But here’s the twist that nobody saw coming: Luffy might not be the one to face the Sword of God directly. Some of the most compelling recent coverage points to the Elbaph arc setting up an unexpected final Straw Hat member who could play a crucial role in the God Devil Fruit theory. If there’s one more crewmate to join before the final war, their connection to the Sword of God’s origins could be the linchpin of everything.
The Brook Connection: Why the Void Century Matters More Than Ever
We can’t talk about the Sword of God without mentioning Brook. Recent chapters have hinted at Brook’s unexpected connection to the Void Century, and if that thread leads back to the Sword of God’s origins, we’re looking at one of the most shocking reveals in shonen history. Brook has been the comic relief for two decades — what if Oda’s been hiding the most important lore clue in plain sight?
The fact that Brook’s Yomi Yomi no Mi grants him mastery over his own soul raises a chilling question: what if the Soul King’s power has something to do with the souls consumed or corrupted by the Sword of God? The Ancient Kingdom didn’t just fall — its people were erased. And Brook is the man who cheated death itself.
What the Final War Will Actually Look Like
Based on everything we know about the Sword of God and Imu’s powers, here’s what the final battle might involve:
- Multiple fronts: Imu won’t fight alone. The Holy Knights, the Five Elders, and potentially the remnants of Rocks’s crew (remember, Loki and Imu already clashed in Elbaph) will create chaos across the battlefield.
- The Sword of God as the centerpiece: Imu’s blade will be the focal point of the Straw Hats’ assault. Breaking or neutralizing it could be the objective, not necessarily defeating Imu in direct combat.
- Gear 5’s true awakening: Luffy’s Nika form may have stages we haven’t seen yet. Some fans theorize a “Gear 6” or a Sun Ring evolution that would represent the full restoration of Nika’s original power.
- The Ancient Weapons turn against the World Government: Pluton, Poseidon, and Uranus could switch sides. If the Ancient Kingdom’s legacy is one of liberation, these weapons might respond to the will of the people rather than Imu’s commands.
The One Thing Oda Has Been Hiding Since Chapter 1
Here’s the theory I’m most excited about: the Sword of God might not be Imu’s weapon at all. It could belong to the Ancient Kingdom — the true “God” weapon — and Imu simply stole it. Everything about the World Government is built on theft and lies: they stole the history, they stole the power, and they stole the name of God itself.
If that’s true, then Luffy doesn’t need to destroy the Sword of God. He needs to reclaim it. And the moment the sword recognizes the true heir of Nika’s will, the entire power structure of the One Piece world comes crashing down.
What Do You Think?
The Sword of God changes everything we thought we knew about Imu, the Void Century, and the final war. Is it Imu’s original weapon, or a stolen artifact of the Ancient Kingdom? Does it connect to Brook’s mysterious past? And will Luffy’s Gear 5 be enough to counter it?
Drop your theories in the comments. The Elbaph arc is only getting started, and Oda has proven time and time again that the truth is always stranger — and more brilliant — than anything we could predict.
