22Why Did Nefertari Lily Betray The Other Nations?
For a long time, fans were under the impression that all twenty nations were loyal to the World Government, but it turned out that wasn’t the case. Nefertari Lily,the ruler of Alabastaat the time, turned against the other 19 nations for unknown reasons.
Due to her actions, the Poneglyphs were released into the world. This enraged Imu, and they probably ordered her execution. For now, it remains unclear why Lily retracted her support after initially deciding to help them. As the story progresses further, this particular mystery will definitely be unraveled.

21Who Is The Man With Burn Scars?
Toward the end of the Wano Country arc, Eustass Kid revealed that in order to leapfrog others in the race for One Piece, they needed to find the man with the burn scar. But they had no idea where to find him. Judging from their statement, it is safe to say that this person will drastically affect the future ofOne Piece.
The man with the burn scar was also mentioned by the Blackbeard Pirates. So, there is more than one crew who knows about his existence, and they will try to chase him down at some point.

20What Is Luffy’s Dream?
Luffy is the main protagonist of the series, so most details about his life are known to the fans. However, the one big thing that the audience still doesn’t know about him is what his dream really is.
Luffy has only told his dream to a handful of characters, but he has never publicly revealed what it is. Sure, he talks about being the Pirate King, but that’s not the only thing that he wishes to achieve. There is more to his dream than meets the eye. For a long time, even his crew didn’t know about what their captain wanted, and he only told them about it after they left Wano.

19Who Are Franky’s Parents?
Franky is the shipwright of the Straw Hat Pirates. He joined the crew after the Enies Lobby arc, where he played a key role in helping the heroes rescue Robin from the clutches of CP9.
As a child, Franky was abandoned by his parents, after which Tom took him in and raised him. Under Tom’s tutelage, Franky learned a lot. Oda is known for saving characters and using them later in the story. So, there is a chance that the truth about Franky’s parents will come to light in the upcoming arcs.

18What Is The One Piece?
One Piece is the greatest treasure in the world. It was found by Gol D. Roger many years ago, but instead of taking it, he simply laughed at the sight of it. Roger believed that his crew arrived too early, so they left the treasure untouched and disbanded.
Not long after, Roger turned himself in to the Marines, and his execution was held in Loguetown. Before being executed, Roger confirmed that he left One Piece on a certain island, waiting to be claimed. The legendary treasure is unquestionably one of the biggest mysteries in the series, and it will be answered toward the end.

17What Is Kuma’s Lineage?
In the Egghead Island arc, it was revealed that Bartholomew Kuma belongs to a special race. It is unknown what race the former Shichibukai belongs to, but it wouldn’t be a stretch to believe that it is now extinct.
Previously, Big Mom had stated that her island was missing three races— giants, Lunarians, and one unknown race. It is possible that Kuma belongs to this unknown race, which should be disclosed in the Egghead Island arc.

Resolved:It has been confirmed that Kuma belongs to an ancient race known as Buccaneers.
16The Ancient Kingdom
The ancient kingdom existed before the Void Century. According to Clover, this ancient kingdom was so wealthy and powerful that other kingdoms feared it. As a result, twenty kingdoms banded together to destroy this civilization and wipe out all trace of its existence.
The twenty kingdoms that eradicated the ancient kingdom would go on to form the World Government. Recently, in the manga, it was confirmed that this kingdom was technologically very advanced, which is another reason why the other kingdoms feared its existence. The name of this kingdom is still unknown, and there is no information about who inhabited it.

15Zunesha’s Punishment
Zunesha is a gigantic elephant that endlessly wanders in the sea while carrying the Mokomo Dukedom on its back. It is nearly impossible to find it without a vivre card because it constantly moves from one location to another.
Momonosuke stated that Zunesha is forced to travel as a punishment for a crime that it committed in the past. What makes this more interesting is the fact that Zunesha was acquainted with Joy Boy.

14Why Was Nefertari Cobra Murdered?
Nefertari Cobra was the ruler of the kingdom of Alabasta. Cobra was a kind ruler, who cared about his subjects and when Crocodile tried to take over the country, he tried his very best to stop the Shichiukai from causing any harm to them.
After the Alabasta arc concluded, Cobra only made an appearance in the Levely arc, where he voiced his concerns over the existence of the Shichibukai system. Many other kings also shared the same opinion as Cobra, and it led to the dissolution of the Shichibukai system. Needless to say, Cobra was overjoyed, but his happiness didn’t last for long as he was murdered. The Marines released a statement in which they named Sabo as the culprit. Later, Sabo assured Dragon that he had not killed Dragon. This raises the question, “who killed Cobra and why?”

Resolved:Nefertari Cobra was killed by Im and the Five Elders after he learned about the true ruler of the world.
13Shanks' Abilities
Shanks is arguably one of the most popular characters inOne Piece(as proven by his high ranking amongst many popularity polls). Despite this, Shanks is a mysterious character. He’s incredibly notorious, despite not appearing frequently enough to know what his abilities areother than his absurdly strong Conqueror’s Haki. Fans have speculated that Shanks is not a Devil Fruit user due to his ability to swim, but beyond that, very little is known.
Hints at Shanks' immense power can be gathered from his status as one of the Four Emperors of the New World, his history with the infamous Roger Pirates, and his overall reputation. But even with these accolades, there still has been very little demonstration of Shanks' fighting capabilities, which is odd considering that the show has demonstrated how Gol D. Roger fights, but not Shanks.
