With nearly 30 years of storytelling, One Piece has built one of the richest worlds in anime. But even with so many revelations, Eiichiro Oda has deliberately kept major secrets hidden, ensuring that fans continue speculating until the very end. Some mysteries shape entire arcs, while others are still just teased in passing.
Here are the 10 biggest unresolved mysteries in One Piece that fans are still waiting to see answered.
10. What Is the Will of D?
The enigmatic “D” initial appears in the names of Luffy, Roger, Blackbeard, and other world-shaking figures. They’re called the “natural enemies of the gods,” opposing the Celestial Dragons and World Nobles. But the true purpose of the D Clan remains unknown. When the full truth is revealed, it could change the entire One Piece world.
9. Who Is Imu?
The supposed “empty throne” of Mariejois was meant to symbolize equality. Yet the Five Elders bow before Imu, the true ruler of the world. Their identity, origin, and motives are one of the story’s most explosive mysteries, tied directly to the series’ endgame.
8. What Is Luffy’s Real Dream?
Becoming Pirate King isn’t Luffy’s only ambition. In flashbacks with Ace, Sabo, Shanks, and even his crew, Luffy mentions another dream — one Oda censors from readers. Based on the Straw Hats’ shocked and amused reactions, it seems childish yet world-shaping. What exactly Luffy wants beyond the One Piece remains a tantalizing puzzle.
7. What Happened During the Void Century?
A full century of history has been erased, with only Poneglyphs preserving fragments of truth. The Void Century holds answers about the Ancient Kingdom, the World Government’s rise, and the origin of weapons like Poseidon and Pluton. Uncovering it could expose why the World Government fears history itself.
6. What Is Monkey D. Dragon’s Goal?
Dragon is the world’s most wanted man, leader of the Revolutionary Army, and Luffy’s father. But beyond rebelling against the World Government, his ultimate ambition remains unclear. When Oda finally pulls Dragon into the spotlight, the balance of the world will surely shift.
5. How Can Blackbeard Wield Two Devil Fruits?
The rule of the world is clear: one Devil Fruit per person. Yet Blackbeard somehow stole Whitebeard’s Gura Gura no Mi after already having the Yami Yami no Mi. Is it due to his bizarre body, hinted at when Luffy and Zoro noted “he’s not a normal man”? Or is it tied to the Will of D and his strange physiology?
4. Who Was Joy Boy?
First referenced in Fishman Island, Joy Boy is tied to the Poneglyphs, Noah, Zunesha, and even the legendary Nika. We know Joy Boy wielded the Hito Hito no Mi: Model Nika — the same fruit Luffy awakened. But his true story, promises, and role in the Void Century remain one of the series’ ultimate reveals.
3. Who Is the Man With the Burn Scar?
Before Egghead, Kid mentioned a mysterious figure known as the “man with the burn scar,” believed to be essential in reaching the One Piece. Ships near him are said to be swallowed whole. His identity is still unknown, sparking wild theories. Could he be a new character — or someone hidden in plain sight?
2. What Are the Florian Triangle Monsters?
At the end of Thriller Bark, the Straw Hats glimpsed shadowy colossi so massive they dwarfed even Moria’s giant ship. Fans connected them to Japanese umibōzu folklore, but Oda has left their nature unexplained. Will they resurface in the Final Saga, or remain an eerie unresolved mystery?
1. What Is the One Piece?
The treasure that started it all. Roger laughed upon finding it, and the World Government fears its revelation. Is it material wealth, knowledge, freedom, or something else entirely? After decades of clues through Poneglyphs, prophecies, and Joy Boy’s legacy, the truth of the One Piece remains anime’s greatest unanswered question.
Conclusion
Oda has masterfully woven One Piece with mysteries that keep fans engaged long after each chapter or episode ends. From the Will of D to Joy Boy and the treasure itself, these puzzles are more than plot devices — they’re the heartbeat of the story.
As the Final Saga unfolds, one thing is certain: every answer will raise even bigger questions, until the day Luffy finally finds the truth of the One Piece.
