ONE PIECE Analysis! – Summary of the Ancient Weapon Pluton! Is It a Flying Ship? An Airship That Can Fly to the Moon? Constructed by the Kozuki Family in Wano Country?

In the manga “ONE PIECE,” the “Ancient Weapons” are shrouded in mystery. They have appeared since the early stages of ONE PIECE and are crucial items related to the core of the story, much like the ONE PIECE itself.

The first of these to be introduced is the “Ancient Weapon Pluton,” a world-shaking battleship that was one of the major reasons the former Warlord of the Sea, Crocodile, invaded the kingdom of Arabasta. It has now been revealed that the hiding place of the Ancient Weapon Pluton is in Wano Country.

In this article, we will thoroughly explore the “ominous identity of the Ancient Weapon Pluton.”

Ancient Weapon Pluton: The “World’s Worst Battleship”

First, let’s review the information about the Ancient Weapon Pluton.

The Ancient Weapon Pluton is known as the “World’s Worst Battleship.” Rob Lucci of the intelligence agency CP9 was so determined to obtain Pluton’s blueprints from Franky that he and the World Government had infiltrated Water Seven for years.

According to Crocodile, who planned to invade the kingdom of Arabasta, the Ancient Weapon Pluton has the firepower to obliterate an entire island with a single shot. Considering it is a battleship, it likely has massive cannons mounted on its deck.

Pluton is thus regarded as the worst monstrosity in shipbuilding history. It possesses the destructive power to drastically change the world’s power balance, making it the ultimate weapon sought by both the navy and pirates. Therefore, the Ancient Weapon Pluton is considered the most dangerous battleship in human history.

The Blueprints of the Ancient Weapon Pluton Have Been Destroyed!

It is confirmed that the Ancient Weapon Pluton is a “ship.” This contrasts with the Ancient Weapon Poseidon, which is the mermaid princess Shirahoshi who commands the Sea Kings. Since Pluton is a physical object, blueprints for its construction exist.

The blueprints for the Ancient Weapon Pluton were owned by a shipwright named Tom.

Tom, a Fish-Man who also built the pirate ship Oro Jackson for the Roger Pirates, somehow came into possession of Pluton’s blueprints. It is speculated that he might have obtained them through Gol D. Roger, who reached Laugh Tale and uncovered the secrets of the Ancient Weapons.

Before his execution by the World Government, Tom passed the blueprints to Iceburg. Iceburg, sensing danger, eventually entrusted them to Franky. Interestingly, Franky hid Pluton’s blueprints inside his own body.

Upon seeing the blueprints, both Iceburg and Franky were astonished, exclaiming, “What is this for…?” and “Can humans really build this…?” Even Tom, the world’s greatest shipwright, said that constructing Pluton would bring about the end of the world, highlighting the terrifying nature of the Ancient Weapon Pluton.

To prevent it from falling into CP9’s hands, Franky ultimately burned the blueprints himself. This means it is practically impossible to reconstruct the Ancient Weapon Pluton from scratch. However, there is no need to rebuild it, as the Ancient Weapon Pluton already exists in a certain country.

Hiding Place: The Ancient Weapon Pluton Was Hidden in Wano Country

Next, let’s explore the hiding place of the Ancient Weapon Pluton.

It appears that the Ancient Weapon Pluton was hidden in Wano Country. Crocodile, a former Warlord of the Sea, investigated the Poneglyph in the kingdom of Arabasta to find Pluton’s location, but he was refuted by Nico Robin, who can read ancient texts.

As a result, various theories emerged in the ONE PIECE community, such as the idea that Pluton was Noah’s Ark from Fish-Man Island or the Ark Maxim from Skypiea. Another theory suggested that Franky, who possessed the blueprints for a long time, might have built Pluton himself.

However, all these theories were eventually proven wrong. In hindsight, if any of those had been Pluton, Nico Robin, who saw them firsthand, would have recognized it.

Did the Kozuki Family Construct the Ancient Weapon Pluton?

Conversely, it raises questions about why Nico Robin stayed silent about Pluton’s location until Luffy happened to awaken Gear 5 and defeated Kaido. Wano Country had been under the control of Kurozumi Orochi for a long time, so no one knew about the existence of the Ancient Weapon Pluton.

In fact, the only person who knew its location seemed to be Kozuki Sukiyaki. This strongly suggests that the Kozuki family might have constructed the warship known as the Ancient Weapon Pluton. The Kozuki family, known for their craftsmanship, created the Poneglyphs and Seastone. Pluton might be one of their creations as well.

Furthermore, the Nefertari family, which rules the kingdom of Arabasta, was originally part of the Celestial Dragons (World Nobles). Wano Country, on the other hand, is an isolated nation that never joined the World Government. Both share the trait of keeping their distance from the Celestial Dragons.

Why was the Ancient Weapon Pluton in Wano Country? And why was its location inscribed on the Poneglyph in the kingdom of Arabasta? It’s speculated that the Nefertari family might have renounced their status as Celestial Dragons either to protect the Ancient Weapon Pluton or to connect it to the D clan.

Is the Ancient Weapon Pluton an Airship?

Next, let’s consider why the Ancient Weapon Pluton was hidden in Wano Country.

In conclusion, it’s possible that an adult Kozuki Momonosuke could use his “Flame Clouds” to lift the Ancient Weapon Pluton. In other words, the world’s worst weapon, Pluton, might function as an airship, flying through the sky. This suggests the potential for pirates to become sky pirates.

In fact, Kaido used Flame Clouds to lift the massive Onigashima island. While the exact size of Pluton is unknown, an adult Kozuki Momonosuke should be able to lift a warship. He has already demonstrated his ability by safely landing the gigantic Onigashima.

The New Onigashima Project could have been laying the groundwork for the “Pluton as an airship” theory.

Could the sky pirate Ancient Weapon Pluton fly to the moon?

Additionally, during the Fire Festival, lanterns called “sky boats” were floated into the night sky. The name “sky boats” evokes the image of an airship. Why did the people of Wano Country name these floating lanterns “sky boats”? This could be a clue that the Ancient Weapon Pluton hidden in Wano Country is indeed an airship.

Thus, it’s possible that in the final chapter of ONE PIECE, the Ancient Weapon Pluton could be used to travel to the moon, which has deep ties to the D family. This suggests that Pluton might be the key to a new arc involving space pirates.

If the Ancient Weapon Pluton is as large as its reputation suggests, it might also serve as a Noah’s Ark, carrying people to safety. Like the historical battleship Yamato, its immense size would make it an easy target, implying that it could have purposes beyond just offensive capabilities.

There’s also the possibility that the Ancient Weapon Pluton could be powered by Poseidon’s Sea Kings, driving the massive warship Pluton.
