The Exploration Of The Ancient Weapons' Power

Delving into the mysteries of the Void Century reveals a profound connection with the ancient civilization of the Ancient Kingdom and their enigmatic creations, the Ancient Weapons. Unveiling the secrets of this lost era has the potential to resurrect the power and significance of these formidable artifacts, thereby reshaping the delicate balance of power in the world. The emergence of these ancient weapons could ignite massive conflicts and forge unexpected alliances as factions vie to control or eradicate these sources of immeasurable power. Among the known Ancient Weapons, Poseidon possesses the ability to communicate with the mighty Sea Kings, adding to its mystique and desirability.

The quest for Gol D. Roger's treasure and the search for the road poneglyphs have already caused turmoil within the Grand Line. The revelation of the existence and true importance of the ancient weapons would amplify these tensions, potentially driving even the closest of friends to become adversaries. Understanding the history of the Void Century would shed light on Poseidon's true nature and elucidate the deep connection between its wielder and the enigmatic Sea Kings. This knowledge would provide insights into their purpose and the immense influence they can exert over the vast seas, allowing for a greater comprehension of their potential and the implications they hold for the world at large.

The Three Ancient Weapons

In the world of One Piece, the Ancient Weapons are renowned as incredibly potent instruments of mass destruction, possessing the capability to bring about the total annihilation of the world. Their immense power is so formidable that they were named after deities, namely Pluton, Poseidon, and Uranus, drawing parallels to the godlike forces they embody. The significance of the Ancient Weapons becomes evident when examining the enigmatic Void Century, an essential component of the overarching plot in the One Piece universe.

During the distant past, the enigmatic Ancient Kingdom, whose name remains unknown to fans, flourished as a powerful entity. However, this era witnessed a monumental shift in power due to a war involving multiple kingdoms, with records of this conflict largely eradicated. The details of this century-long void, which transpired approximately 900 to 800 years ago, remain shrouded in mystery. At its conclusion, the World Government was established by 20 kings, whose descendants relocated to the lofty city of Mariejois and eventually became known as the Celestial Dragons. It is widely believed that the Ancient Weapons were either "created" or employed by the Ancient Kingdom in their fateful war against a formidable adversary from their past.

While the true nature and events of the Void Century continue to elude fans, the presence and significance of the Ancient Weapons signify their pivotal role in shaping the world of One Piece. Unraveling the mysteries surrounding these legendary artifacts and their origins holds the potential to unveil the secrets of the past and shed light on the grand history that has influenced the present state of affairs.


Among the Ancient Weapons, Uranus remains a mystery to One Piece fans, with little to no information available about its nature or capabilities. However, the other two Ancient Weapons have been explored by Oda to some extent. The first of these weapons to be introduced in the story is Pluton, which holds immense significance in the history of One Piece. It is believed that the Ancient Kingdom utilized Pluton to resist their powerful adversaries. Pluton takes the form of a warship that was constructed over 800 years ago on the island of Water 7. Its power is described as being so immense that a single attack has the potential to obliterate an entire island. To safeguard this devastating weapon, the blueprints of Pluton were passed down through generations within the shipwrights of Water 7, until they eventually fell into the hands of Franky. Trusting in Nico Robin, Franky destroyed the blueprints, ensuring that they would not be misused. Presently, the whereabouts of Pluton remain unknown.

Additionally, Princess Shirahoshi, a mermaid in One Piece, has been linked to the Ancient Weapons. Although the exact connection between Shirahoshi and the Ancient Weapons is yet to be fully revealed, her importance in the grand scheme of these powerful artifacts is hinted at throughout the story. As the narrative progresses, more details about Shirahoshi's role in relation to the Ancient Weapons may be unveiled, adding further depth and intrigue to the ongoing plot of One Piece.


In subsequent story arcs, Oda introduced another Ancient Weapon known as Poseidon to the fans. Unlike Pluton, Poseidon is not a weapon or warship but rather a mermaid who is reborn every few centuries in the world of One Piece. It is believed that Poseidon's power will eventually be guided by a chosen individual to ensure its proper use. The identity of the previous Poseidon remains a mystery, but currently, the daughter of King Neptune and Queen Otohime, Shirahoshi, possesses this extraordinary ability. As one of the strongest characters in the One Piece world, Shirahoshi possesses the potential to become a devastating force.

Poseidon's unique power lies in her ability to communicate with and command the mighty Sea Kings, making her an invaluable ally to those who befriend her. The Sea Kings are fiercely loyal to her, and while she may not possess great physical strength herself, the power she wields surpasses even the mightiest individuals in the world. To comprehend Shirahoshi's immense strength, one need only consider the Noah, a monumental ark cherished by the Fishmen and Merfolk who believe it will transport them to the surface when Joy Boy returns to fulfill his promise. The Noah itself is larger than half the size of Fishman Island, an already colossal landmass. Yet, with just a few commands from Shirahoshi, the Sea Kings effortlessly halted the Noah's advance. If she desired, Shirahoshi could easily submerge multiple islands and bring about the destruction of the entire world. In the ongoing narrative, Shirahoshi's role as Poseidon will undoubtedly be explored further, unveiling her significance in the story's future developments.
