After more than two decades of adventure, mystery, and world-building, One Piece officially entered its Final Saga in 2022. Eiichiro Oda has spent years weaving together an intricate tapestry of plotlines, and now fans worldwide are on the edge of their seats, wondering how it will all come together. From the true nature of the One Piece treasure to the identity of Imu and the fate of the Straw Hat Pirates, speculation has never been more intense.
The beauty of One Piece lies in its unpredictability. Oda has consistently subverted expectations, turning seemingly minor details into game-changing revelations. As we approach the endgame, let's dive into the most compelling theories circulating in the community right now.
What Is the One Piece Treasure?
The million-dollar question that's been haunting fans since Chapter 1: what exactly is the One Piece? Over the years, theories have ranged from the practical to the philosophical.
Some fans believe the treasure is advanced technology from the Ancient Kingdom, possibly something that could reshape the world's power structure. This would explain why the World Government is so desperate to keep it hidden. Others think it's connected to the Void Century's true history—perhaps documents or evidence that would expose the Celestial Dragons' crimes and legitimacy.
Then there's the more symbolic interpretation: the One Piece might represent freedom itself, or the journey and bonds formed along the way. This would align with Oda's emphasis on adventure and nakama (friendship). However, Oda himself has stated that the One Piece is a physical reward, not just a metaphorical one, which keeps the tangible treasure theories alive.
The most intriguing possibility? It could be all of the above—a treasure that's both physically real and philosophically significant, capable of literally bringing the world together as "one piece."
Joy Boy, Luffy, and the Sun God Nika
The revelation of Gear 5 and its connection to the Sun God Nika fundamentally changed how we understand Luffy's role in the story. We now know that Luffy's Devil Fruit isn't the Gomu Gomu no Mi at all—it's the mythical Hito Hito no Mi, Model: Nika.
But is Luffy actually Joy Boy reincarnated, or is he simply following in his footsteps? The distinction matters. Joy Boy was a figure from the Void Century who made a promise to the people of Fish-Man Island, one he failed to keep. The Poneglyphs he left behind suggest he knew someone would come after him to finish what he started.
Luffy seems to embody Joy Boy's will without being literally the same person. He's making people smile and liberating nations, just as Nika—the legendary "Warrior of Liberation"—was said to do. The parallel is clear: where Joy Boy failed, Luffy will succeed. His awakened powers even change the art style of the manga itself, bringing a cartoonish, joyful energy to battles that reflects the very essence of freedom.
The question remains: what was Joy Boy's original failure, and how will Luffy avoid the same fate?
The Mystery of Blackbeard
Marshall D. Teach might be the most enigmatic villain in One Piece. Unlike other antagonists, Blackbeard doesn't fit any traditional mold—he's cowardly yet ambitious, lucky yet calculating. But the biggest mystery surrounding him is how he possesses two Devil Fruits without dying.
The fan community has developed several theories. The most popular suggests Blackbeard's body is somehow abnormal—Marco once mentioned his body has a "different structure." Some speculate he has multiple souls or personalities inhabiting one body, which would explain his Jolly Roger featuring three skulls. Others think his Yami Yami no Mi (Darkness Fruit) has special properties that allow him to absorb multiple powers.
There's also the Cerberus theory: Blackbeard might have eaten a Zoan fruit that grants him three bodies or forms, like the mythical three-headed dog. This would explain why he never sleeps and why he could host multiple Devil Fruit powers.
Whatever the truth, Blackbeard represents the dark mirror to Luffy—someone who pursues dreams through betrayal and opportunism rather than friendship and determination. Many fans believe he'll be Luffy's final opponent, representing the ultimate ideological clash in the series.
Imu and the Void Century's Secrets
The shadowy figure sitting on the Empty Throne, Imu, might be the series' most mysterious character. We know almost nothing concrete about them—not their gender, their powers, or how they've remained hidden for centuries.
The prevailing theory is that Imu is immortal, possibly through the Ope Ope no Mi's immortality surgery. This would mean someone sacrificed their life in the distant past to grant Imu eternal life. But why? What makes Imu so important to the World Government's power structure?
The Void Century—that 100-year gap in recorded history—holds the key to understanding Imu's role. The Ancient Kingdom that existed during that time was clearly advanced and powerful enough to threaten the twenty kingdoms that would become the World Government. Imu likely played a central role in erasing that history and maintaining the current world order.
The connection between Imu, the Ancient Weapons (Pluton, Poseidon, and Uranus), and Joy Boy's promise suggests that the Final War will be about more than just defeating bad guys—it will be about revealing truth and reshaping the entire world.
The Final War and the Straw Hats' Dreams
As we enter the Final Saga, fans are already speculating about epic matchups. Will Zoro finally face Mihawk to claim the title of World's Greatest Swordsman? Will Sanji confront his past through battles with the Vinsmoke family or Admiral Kizaru? What about Usopp becoming a brave warrior of the sea, or Nami completing her world map?
Each Straw Hat has a dream that's been central to their character since they joined the crew. The genius of Oda's storytelling is how these individual dreams are all connected to reaching Laugh Tale and discovering the truth about the world. Luffy's dream of becoming Pirate King naturally facilitates everyone else's ambitions.
But will the crew stay together after achieving their goals? Roger's crew disbanded after reaching Laugh Tale, and there's a bittersweet poetry to the idea of the Straw Hats going their separate ways once their adventure concludes. However, given the series' emphasis on chosen family and unbreakable bonds, many fans hope (and believe) that the Straw Hats will remain together, perhaps rebuilding the world in a new era of freedom and truth.
The Fun Is in the Speculation
Here's the beautiful truth about One Piece theories: most of them will be wrong. Oda has proven time and again that he's several steps ahead of even his most dedicated readers. He plants seeds for revelations years—sometimes decades—in advance, and then delivers payoffs that nobody predicted but everyone recognizes as perfect in hindsight.
That's what makes theorizing so much fun. We're not trying to spoil the story; we're engaging with it, celebrating the depth and complexity that Oda has crafted. Every wild theory, every crack prediction, every detailed analysis is a testament to how much this series means to millions of fans worldwide.
As the Final Saga unfolds, we're witnessing the culmination of a story that's defined a generation of manga and anime fans. Whatever happens at Laugh Tale, whatever the One Piece turns out to be, and however our beloved Straw Hats' journeys end, one thing is certain: it's going to be an unforgettable ride.
