“One Piece” is currently in its Final Saga, where Oda has promised to reveal some of the series’ biggest mysteries. With the Egghead Arc, he introduced a fascinating twist to the story, unveiling some of the most significant secrets of the world — especially regarding Devil Fruits and the mysterious Void Century.
Now that the story has moved into the Elbaf Arc, Oda continues to gradually reveal major developments, particularly related to the Land of the Giants and their understanding of Sun God Nika. In doing so, Oda has also introduced some intriguing new Devil Fruits, and even the concept of what could be the most powerful Devil Fruit in the entire One Piece universe.
The Concept of Devil Fruit Creation in “One Piece”
Dr. Vegapunk himself discussed the concept of Devil Fruits during the Egghead Arc. While he didn’t explain how they are physically created, he made it clear what he believes their origins to be. Simply put, Devil Fruits are born from the desires of humanity. Vegapunk believes that everything is brought into the world due to people’s desires — and that includes Devil Fruits.
Some people in the One Piece world desire certain realities, while others dream of something completely different. These desires are what lead to the creation of Devil Fruits — which in turn grant people the powers to fulfill those imagined futures. In other words, Devil Fruit users exist in a different dimension of possibility, made real through the wishes of those who came long before them. Vegapunk officially stated this in the Egghead Arc, making it a major revelation in the series.
Considering Vegapunk’s explanation, the door is wide open to infinite possibilities. This helps explain why some powers are bizarre or strangely specific, while others are overwhelmingly strong — all depending on the intensity of the desire behind them. This also ties back to the Skypeia Arc, where physicist Willy Gallon once said, “Everything that humans can imagine is a possibility in reality.”
Combining that quote with Vegapunk’s theory, fans now understand that any ability imaginable can potentially exist in the One Piece world — and among them, Oda has already hinted at the most dangerous power yet in the Egghead Arc.
Did Oda Hint at Most Destructive Devil Fruit in “One Piece”?
Based on everything Oda has revealed about Devil Fruits and their creation, fans know that any power conceived by the human mind can manifest in the “One Piece” world. For instance, lightning exists naturally and also as a Devil Fruit ability. The same applies to fire, wind, and nearly any other element or force of nature. Even more destructive forces, such as magma, earthquakes, or natural disasters, can exist as Devil Fruit powers — proving that if humans can imagine it, it can be made real.
This is where the concept of Motherflame comes in. Fans know that Motherflame is a special energy source in the “One Piece” world — or rather, something that has been artificially created. Essentially, it is described as an eternal and immortal flame with immense power. This energy could be used to solve the world’s problems, provide limitless power, and make life drastically easier for everyone.
However, at the same time, Motherflame can also be weaponized for destruction. To explain, Motherflame has the potential to power the Ancient Weapons, and put simply, it is comparable to nuclear energy — capable of destroying the entire planet.
What’s more, Motherflame could easily exist in the form of a Devil Fruit, just like many other powers in One Piece. If someone had long wished for the powers of Motherflame, it is very possible that a Devil Fruit could have emerged, granting whoever eats it the power to destroy the world.
