15 Biggest Unresolved Mysteries In ‘One Piece’
The anime ‘One Piece’ (1999-2025) has captivated me with its vast world of pirates, epic quests, and secrets buried across the Grand Line. Eiichiro Oda’s masterpiece keeps me hooked with its intricate lore and unanswered questions after over a thousand episodes.
As ‘One Piece’ heads into its final saga, the mysteries surrounding the past, key characters, and the ultimate treasure grow more tantalizing. Here are the 15 biggest unresolved mysteries in the series that have me eagerly awaiting answers, ranked from least to most intriguing.
Florian Triangle Shadows (1999-2025) – Giant Figures with Red Eyes
In the Thriller Bark arc, massive shadowy figures with glowing red eyes appeared in the Florian Triangle’s fog. These towering silhouettes, larger than the giant ship Thriller Bark, suggest unknown creatures or forces lurking in the seas.
I’m curious if these are ancient beings or just a creepy backdrop. Their unclear connection to the broader story makes them a haunting puzzle.
Zoro’s Eye Scar (1999-2025) – The Swordsman’s Hidden Injury
Roronoa Zoro returned after the time skip with a scar over his left eye, which he keeps closed. This mysterious injury from his training with Dracule Mihawk has sparked questions about its cause and meaning.
I’m eager to know if the scar hides a new ability or is simply a battle mark. Oda’s silence on this keeps the intrigue alive.
Crocodile’s Secret (1999-2025) – Ivankov’s Blackmail
During the Impel Down arc, Emporio Ivankov hinted at knowing a secret about Crocodile, using it to sway the former Warlord. The nature of this undisclosed weakness fuels speculation about Crocodile’s past.
I’m intrigued by what Ivankov holds over him. Could it be a hidden history or a personal truth? This secret promises to add depth to his character.
Shanks’ True Power (1999-2025) – The Red-Haired Emperor’s Strength
Shanks, one of the Four Emperors, has shown incredible feats, like stopping a war with his presence alone. Yet, his full combat abilities, Haki mastery, and motives remain largely unseen despite his long-standing role in the story.
I’m excited to see Shanks unleash his true strength, especially with his ties to Luffy. His mysterious power level makes him a wildcard in the final saga.
Man with the Burn Scar (1999-2025) – The Final Road Poneglyph
Introduced in the Wano arc, the Man with the Burn Scar holds the last Road Poneglyph needed to find Laugh Tale. Described as a weather-manipulating figure, his identity is completely unknown.
I’m thrilled at the idea of meeting this key figure. His role in the race for the One Piece makes him a crucial piece of the puzzle.
Ancient Weapons: Uranus (1999-2025) – The Unknown Destroyer
Pluton is a ship in Wano, Poseidon is Shirahoshi’s Sea King control, but the third Ancient Weapon, Uranus, remains a mystery. Its powers and whereabouts are unknown, likely tied to the World Government’s arsenal.
I’m eager to discover if Uranus is a weapon or a person. Its reveal could tip the scales in the coming war against the government.
Giant Straw Hat (1999-2025) – Mariejois’ Hidden Relic
The Reverie arc revealed a giant straw hat, like Luffy’s, in a secret chamber in Mariejois, guarded by Imu. Its massive size suggests it belonged to a giant, possibly Joy Boy, from the Void Century.
I’m fascinated by its link to Luffy’s iconic hat. Could it hold secrets about the ancient past or the One Piece itself?
Voice of All Things (1999-2025) – A Rare Power
The Voice of All Things lets characters like Luffy, Roger, and Momonosuke hear animals and objects, like Poneglyphs or Zunesha. Its origins and why only a few have this ability remain unexplained.
I’m curious about what makes this power so special. Its connection to the Void Century makes it a compelling mystery.
Kozuki Toki’s Origins (1999-2025) – The Time Traveler
Kozuki Toki, Oden’s wife, used her Time-Time Fruit to jump forward from the Void Century. Her reasons for fleeing and her true background are still shrouded in secrecy.
I’m excited to learn why she left her era. Her ties to the ancient past could unlock key details about the world’s history.
God Valley Incident (1999-2025) – A Buried Battle
The God Valley Incident, 38 years ago, saw Gol D. Roger and Monkey D. Garp face off against Rocks D. Xebec’s crew. The island vanished, and details of this clash remain scarce.
I’m eager to uncover what went down in this epic battle. Its links to characters like Shanks and Kuma make it a vital piece of lore.
Blackbeard’s Body (1999-2025) – A Strange Anomaly
Marshall D. Teach, aka Blackbeard, can wield two Devil Fruits, defying normal limits. Marco noted his body is ‘different,’ and his sleepless nature adds to his enigma.
I’m intrigued by what makes Blackbeard unique. Is it a genetic quirk or something tied to the Void Century? His secrets are central to the story.
Imu’s Identity (1999-2025) – The Hidden Ruler
Imu, revealed in the Reverie arc, rules the World Government from the Empty Throne in secret. Their motives, origins, and possible immortality remain completely unknown.
I’m dying to know who or what Imu is. As the power behind the government, their role makes them a key figure in the final saga.
Will of D (1999-2025) – The Inherited Legacy
The ‘D’ initial, carried by characters like Monkey D. Luffy and Gol D. Roger, signifies defiance against the World Government. The meaning of this inherited will is still a core mystery.
I’m excited to find out what the ‘D’ represents. Its link to the ancient past promises a reveal that will shake the story’s foundation.
Void Century (1999-2025) – The Erased History
The Void Century, a 100-year period erased by the World Government, hides the truth about the Ancient Kingdom’s fall. Poneglyphs, read by Nico Robin, are the only clues to this lost history.
I’m thrilled to uncover this hidden past. Its secrets will likely reshape the world and explain the government’s desperate cover-up.
One Piece Treasure (1999-2025) – The Ultimate Prize
The One Piece, left by Gol D. Roger on Laugh Tale, drives the entire series. Its true nature, beyond mere wealth, made Roger’s crew laugh, but remains a complete enigma.
I’m on edge waiting to see what Luffy discovers. The treasure’s connection to Joy Boy and the Void Century makes it the ultimate mystery.
