5. How Did Devil Fruits Come Into Existence?

The Truth About The Devil Fruits Is Unknown

Devil Fruits have existed for quite a long time in the One Piece world. According to Vegapunk, Devil Fruits are a result of the desires of humanity. Since the desires go against nature’s natural evolution, the mother sea decides to hate those who consume Devil Fruits, which is why they sink to the bottom of the ocean.

Still, it does not explain how Devil Fruits came into existence and who was the first Devil Fruit user in the One Piece world.

The Ancient Weapons Exist For A Reason

Long ago, those of the Ancient Kingdom created the Ancient Weapons to combat against the power of the Founding 20. These Ancient Weapons were incredibly powerful. Fans know the names of all three of them to be Pluton, a giant warship, Poseidon, the Mermaid Princess capable of controlling the Sea Kings, and Uranus.

Exactly what circumstances they were created under and how remains unknown. Uranus, in particular, still remains a mystery, and fans will surely find out more about it later down the line.

2. What Was The Name Of The Ancient Kingdom?

The Ancient Kingdom’s Name Is Still Hidden

The Ancient Kingdom is at the center of the Void Century in the One Piece world. This Kingdom is believed to have been a very advanced society, such that even the technology of today that Vegapunk created is not comparable to it. This is one of the reasons why it was destroyed by the Founding 20, who collaborated and waged war on them.

In a war that lasted nearly 100 years, the Founding 20 eventually crushed the Ancient Kingdom. All records about it have since then been erased. However, the Final Saga will unearth everything about the Ancient Kingdom, from its name all the way down to its entire history.
