The Poneglyphs, which were introduced during the Alabasta saga ofOne Piece,are one of the biggest mysteries of the series. Not much is known about them aside from the fact that they contain the details about the history of theOne Pieceworld, and that they are indestructible. As the story progressed, the importance of these Poneglyphs has also increased.

Out of all the Poneglyphs, the four road Poneglyphs are the ones that, when combined, can disclose the location of Laugh Tale which is the final island in the hunt for theOne Piecetreasure. This is why they are the biggest threat to the World Government and they have been actively trying to destroy them.
However, the strange thing about the Poneglyphs is their indestructibility. No one knows how the Poneglyphs were made and how they have been so intact even after so many years. But there is one theory that states that the Poneglyphs were imbued with Haki during their creation, which is why they cannot be destroyed at all.

The Indestructibility of the Poneglyphs inOne Piece
Poneglyphs are enormous, cubic slabs fashioned from an unidentified, unbreakable stone. They are classified into three sorts that can be found all over the world: historical, instructional, and road. The Historical and Instructional Poneglyphs are dark blue, whereas the Road Poneglyphs are deep red.

There are thirty Poneglyphs that have been spread across the islands inOne Piece. It was recently disclosed that the Kozuki family carved them during the Void Century and after that, only Oden, who was a part of Gol D. Roger’s crew, was able to achieve this feat. However, this led toOne Piecefans’ questioning about how they accomplished this given the stone’s indestructibility.
Even theWorld Government, the most powerful institutionin theOne Pieceworld, was unable to destroy a single Poneglyph and ultimately declared a ban on researching and studying about them. This in itself speaks about the strange nature of the Poneglyphs.

Theory Suggests Poneglyphs Are Imbued With Haki
According to a wild theory posted byu/Eastern-Carpenter-71on Reddit, the Poneglyphs, just like the Black Blades, are imbued with Haki which is why they are indestructible. There have only been two black blades sighted by fans thus far, making them extremely unusual. The Black blades are made by imbuing Armament Haki on them continuously.
In theOne Pieceuniverse, Black blades do not appear by chance. Rather, the user must forge them on their own. Mihawk and Ryuma are the only users who have been known to forge the Black blades. It is thought that a Black Blade is far more robust than a conventional blade and nearly unbreakable. They are the only known things other than the Poneglyphs which are termed as indestructible inOne Piece.

Therefore, according to the theory, just like Black blades, Poneglyphs were also made by imbuing Haki in them. This also sits perfectly with Kaido’s comment about Haki being the supreme power inOne Piece. And because Gol D. Roger and Oden were two of the strongest Haki users, they were able to carve out details on the Poneglyphs.
