A Peacekeeper Or Hidden Mastermind

The red-haired pirate was introduced early in the series as Luffy’s inspiration, but how much do we really know about him? Then, in Elbaf, there is the shocking revelation of his twin brother, Shamrock Fingarland.

If Shanks and Shamrock were born into a noble family, why did one become a pirate, and the other serve the Celestial Dragons? Perhaps the most puzzling question of all is, what does Shanks really want? Unlike other emperors, he is not recklessly chasing after the one piece treasure, even though he has the power to claim it.

Red-Haired Shanks One Piece

Yet for years,he remained in the shadow, intervening only when necessary. Is he protecting something or waiting for the right moment to act? Every time we learn something new about Shanks, more questions arise, and as the final saga unfolds, it is clear he is not just a bystander in the series.

9Rocks D. Xebec

The Legendary Captain Of The Rock Pirates

Few pirates in history have ever commanded as much fear and intrigue as the pirate who captained the most dangerous crew. However, with all the legends surrounding him, we still know nothing about him.

The last known information about him was inthe God Valley incident, where Monkey D. Garp and Gol D. Roger defeated him. Since the event is shrouded in mystery, is he truly dead, and what happened at God Valley that caused his empire to collapse in a single day?

Rocks D Xebec of the Rock Pirates

There is still so much to know about him, because why the World Government will go through the length of erasing his legacy is still unknown.

The Walking Relic Of The Past

The elephant that provides a home to the Minks is a relic of the past and has been wandering the sea for ages. When she heard the rhythm of Luffy’s heartbeat in Wano, she reacted joyfully and was not confused about what it meant.

Her reaction to Luffy’s heartbeat means she knew Joyboy, and the mysterious figure was most likely there when history was rewritten. What does Zunesha know about the Void Century? Was it Joyboy’s companion, or maybe even a weapon of the past?

Zunesha One Piece

Zunesha remains bound by a punishment from 800 years ago, sowhat crime did she committhat warranted such an eternal sentence?

7Marshall D. Teach (Blackbeard)

The Unpredictable Pirate

There are many races in the One Piece series, and the race of Blackbeard is currently unknown. He is the only person to wield two devil fruits and a part of the D people.

7 One Piece Arcs With Best Fights

From emotional duels to era-defining clashes, these 7 One Piece fights stand among the best.

However, despite being one of the most important characters in the series, almost everything about him remains a mystery. During the era of Gol D. Roger, Buggy mentioned to Shanks that Blackbeard had never slept in his life, which is ridiculous.

Blackbeard One Piece

However, the fact that he can consume two devil fruits makes him different from other normal people in the series. Also, what is his backstory, and what are his true goals in the grand scheme of events?

6The Nobles Of Mariejois (The Holy Knights and The Five Elders)

The World Nobles

The five elders are the highest authority in the world government and have been manipulating history in the shadows for centuries. The revelation of theirpowers on Egghead Islandincreased the curiosity to know their true nature.

The fact that the five elders are shaken by the existence of Luffy and his devil fruit depicts that there are more secrets to unravel about them than just their witchy powers. The holy knights are a force that even the Revolutionary army fears.

If the five elders control the world through manipulation, then the holy knights are the enforcers or soldiers who carry out their wills and plans. In other words, these two forces are like the gatekeepers dictating the world, serving Imu.

5Monkey D. Dragon

The Revolutionary Army Leader

Dragon is the leader of the Revolutionary Army, Luffy’s father, and the son of Marine hero, Garp. He is an enemy of the World Government, a member of the D clan, and his past is still a mystery.

Also, what prompted Dragon to form the revolutionary army? Was it something he witnessed at Mariejois when he was a Marine officer? Another intriguing question surrounding Dragon is the nature of his devil fruit.

The revolutionary army seeks to dismantle the world government, yet he has never mentioned anything concerning the lost history. So, does he already know the truth?

4The Nefertari Family

The Oppositionist Of The Past

The Nefertari were one of the founding families of the World Government, but their ancestor, Lili, did not jointhe Celestial Dragonsand vanished without a trace. The question is, why is Imu so fixated on the Nefertari royal family?

Also, Cobra’s murder by Imu is just another reminder of the high stakes of the Nefertari family in the series, and why it was so dangerous for anyone to seek the truth. And then there is Vivi, who is also a target of Imu and a carrier of the will of D.

Perhaps Vivi carries the will of Lili, who is an enemy to Imu and the five elders, but all these are still speculations. Hence, the Nefertari family’s history is filled with half-baked truth, but they are definitely a key factor in the final saga.

3Captain John

The Man With The Legendary Treasure

Like Xebec, Captain John is also a figure in the past and a member of the Rock Pirates. He was part of the crew with powerfulfigures like Kaido, Big Mom, and Whitebeard, which means he was also not ordinary.

7 Best Outfits of Straw Hat Pirates in One Piece

Clothing defines a character’s style and personality. Here are some of the best outfits in One Piece.

He was betrayed and killed by his crewmembers, and his treasure is hidden in a place no one has been able to find. His treasure remains one of the series' unsolved mysteries, and Buggy the Clown is obsessed with finding the lost treasure.

In Marineford, Buggy puts his life in danger to get a relic to find John’s treasure from Luffy. Why does a coward like Buggy put his life at stake and dedicate years searching for the treasure, or could his treasure hold a secret to unraveling a bigger mystery in the series?

An Echo Of The Past

The existence of Joyboy in the past still continues to shape the future events in the series, yet so little is known about him. Why did he leave an unfulfilled promise that still influences the present day, and who was he, a warrior or a liberator?

Joyboy keeps resurfacing at the most critical point in the story, so his importance cannot be overstated because he threatens the existence of the World Government. He is tied to the Void Century, and now, through Luffy, his will seems to have been reignited.

Is Joyboy a single person, or was he the one who originally wieldedthe power of Nika? Despite these questions, one clear thing is that he is the key to understanding the greatest mysteries in the series.

The Shadow Ruler Of The World

The enigmatic Imu is currently the ruler of the world and the only one who sits on the empty throne. The world government’s highest-known authorities, the five elders, seek his acknowledgment before carrying out any occasion.

How long has Imu ruled from the shadows? The Void Century, the Great Cleansing, and the eradication of Lulusia all point to him as he controls the world behind the curtain. If he has been around since the days of Joyboy, how is he still in existence?

What makes Imu’s role even more unsettling is why he chose to kill Cobra, planned to eliminate Vivi, and even sought to erase the will of D and Joyboy’s existence. What connection do these characters have to the truth he wants to suppress, and what is he afraid of?
