Now, the final saga ofOne Piecehas well and truly begun and, as such, Oda himself has promised to draw the biggest mysteries of the story in this section. From the Ancient Weapons to the One Piece itself, here are the biggest questions thatOne Piece’sfinal saga will provide an answer to.
9What Is The One Piece?
Quite possibly the biggest question in every fans' minds is regarding the One Piece itself.Gol D. Roger, the Pirate King, started the Great Pirate Era and everyone since then has been looking to get their hands on this grand treasure.
Despite having received some hints about it, nobody really knows what the One Piece truly is. It is only in the final saga that the truth about the treasure will be revealed to the fans once Luffy reaches Laugh Tale and finds the treasure himself.

8What Happened During The Void Century?
The Void Century is a blank period of 100 years that took place 800-900 years before the current time of theOne Pieceworld. No information about this period is known to people and it has, quite craftily, been hidden from the entire world.
Although there are individuals who know about the happenings of the Void Century, the fans don’t know what transpired during this 100-year blank in history. Once Luffy reaches Laugh Tale, the true history of the world will finally be revealed.

7What Is Shanks' Motive?
Shanks is one of the Yonkoof theOne PieceWorld. Introduced quite early into the series, very little is known about him so far. Shanks has sidelined himself from the majority of the events that have taken place in the Great Pirate era.
It was only after Luffy defeated Kaido that he made his interest in finding the One Piece known. Shanks' motives remain unknown to this day and fans hope to find the answer in the last saga of the story.

6Who Was Joy Boy?
Joy Boy is a mysterious characterwho lived long ago in the Void Century. It was first brought up during the Fishman Island arc where Nico Robin found an apology written by him on a Poneglyph.
Since then, his name has been mentioned on quite a few occasions, however, no concrete story about Joy Boy has been revealed yet. SinceOne Piece’slast saga will delve into all the mysteries of the world, fans will also find out more about him.

5Where Did Devil Fruits Come From?
Devil Fruits are the main power systemin theOne Pieceworld and were introduced in the very first chapter of the series. These fruits have tremendous powers and hold great significance to the story.
So far, little to nothing is known about how they came to be and what secrets they hold within. Oda has previously mentioned that Vegapunk would be the one to reveal the secrets of the Devil Fruits. Since he’s likely going to be a key character and the last saga, fans should expect this question to be answered as well.

4Who Is Luffy’s Mother?
Luffy’s family has always been quite intriguing toOne Piecefans. Nearly all members of his family are big shots, such as Garp, the Navy Hero, Dragon, the Revolutionary Army leader, and his brothers, both of which are incredibly famous.
Luffy’s mother has not been revealed to the fans so far, however, when she does make an appearance, she will likely carry a similar pedigree.

3What Are The Ancient Weapons?
The Ancient Weapons are powerful toolsof mass destruction that exist in theOne Pieceworld. Going by the names of gods in Uranus, Poseidon, and Pluton, these weapons carry tremendous significance to the true history of the world.

So far, nothing apart from their destructive powers has been revealed to the fans. In the last saga, these weapons could very well come into play and fans expect Oda to reveal all the answers about the Ancient Weapons in this saga of the story.
2What Is The D Clan?
The D name is quite peculiar in theOne Pieceworld. Those carrying this initial are known to be the enemies of the Gods. So far, very little is known about the true meaning of this initial and why it holds such significance to the main plot.
In the last saga, however, fans will certainly find out more about what it means and where it comes from. These questions could very well tie to Joy Boy or Nika, as well as the Ancient Kingdom.

1What Was The Ancient Kingdom?
The question of the Ancient Kingdom will finally be answered inOne Piece’slast saga. During the Enies Lobby arc, it was revealed that long ago in the Void Century, a very prosperous kingdom existed.
Somehow, the very existence of this kingdom was wiped out and nothing is known about it right now. Once Luffy finds theOne Piece, fans will also know about the true history of the Ancient Kingdom and the many battles that it fought against the 20 Kings.
