Ever since Crocodile first mentioned the ancient weapon Pluton way back in the Alabasta arc, many fans have wondered at the true nature of the three Ancient Weapons; Pluton, Poseidon, and Uranus. As the series has gone on, we have learned a bit about the former two, but not the last.

Pluton has long since been revealed to be a battleship of extraordinary power; the Poneglyph hidden beneath Alabasta contained information about its location, while the blueprints for it were eventually handed down to Franky, who destroyed them to keep them out of the government’s hands.

Poseidon was first mentioned on Skypeia, and it wasn’t until Fishman Island that we learned exactly what (or rather, who) it was; a mermaid princess, born with the ability to communicate and command the titanic Sea Kings that populate the world’s most dangerous waters.

All that is currently known about Uranus, however, is that it is another weapon similar in strength to the previous two.

These three weapons are all named after gods in mythology, and the two we have learned about so far have both had some connection to their name.

Poseidon was named after the Greek god of the sea, child of Cronus and brother to Zeus and Hades. This is fitting, as Poseidon is often depicted as having full control over all of the sea’s creatures.

Pluton is a bit trickier, but still feasibly connected; It is named after Pluto, the Greek god of the Underworld, also known as Hades. Having been made to select his domain last, after Zeus (Jupiter) chose the sky and Poseidon (Neptune) chose the sea, Hades was made to rule the Underworld. While Hades himself is not typically associated with boats, someone in the Underworld is; Charon the ferryman, who transports newly deceased souls across the rivers Styx and Acheron that separate the world of the living and the world of the dead. Thus, Pluton could be seen as a subtle nod to Charon’s ferry, delivering people to death.

Uranus, as noted above, is not representative of Zeus; Jupiter is Zeus’ counterpart. Uranus was a god even older than they, husband and son of Gaia and personification of the sky. It was he who sired the first generation of Titans, including Cronus, the father of Zeus, Poseidon, and Hades, among others.

A common theory for Uranus’ role as a weapon is that it is some form of weather control machine; I have seen a number of fans who believe it may be in the possession of the Revolutionary Army, or possibly even Dragon himself, given that Poseidon is also a living being.

My theory, however, is that we have already seen Uranus. Or at the very least, a prototype of sorts. Where, you may ask?

The Ark Maxim!
The Ark Maxim, Enel’s ultimate weapon, was quite the impressive piece of work. A large vessel that, by combining chemicals with Enel’s own incredible powers, was able to destroy an entire island by producing a gigantic thundercloud.
It is stated that Enel directed Gan Fall’s men to construct the ark after he usurped his role as “God”, but I find this somewhat strange. While Enel does not seem to be particularly stupid, neither does he seem especially intelligent. While it is certainly possible that he could have designed the Ark Maxim on his own, I have yet to find evidence that he was knowledgeable to create such a devastating weapon. I believe that Enel, at some point in time, discovered the blueprints to Uranus and, unable to recreate its advanced technology with what was available to him or with his own knowledge, he modified its design so that he could reproduce its power to a smaller, though still impressive scale by using his own powers.

Enel likely incorporated large amounts of gold and dials in order to make up for the technological deficiencies he may have encountered, seeing as the former’s high conductivity would make for a good material thanks to his electrical powers.

Usopp was able to use gas from a Breath Dial during his battle with Luffy to create an enormous explosion using only a small flaming projectile to ignite the gas. Enel did something similar with his lightning.

Considering that the ancient civilization(s) who built the ancient weapons were advanced enough to create a battleship that even now is feared by the World Government, it is reasonable to assume that they had a means of producing similar destructive forces without the aid of a Devil Fruit like Enel’s.

It is also possible that the ancient weapons were invented by aliens, such as those Enel encountered when he reached the moon. It is stated in the translation of the cover story below that the Birkans descended to the “Blue Planet” because their home was low on resources; perhaps they brought the blueprints to Uranus to the sky islands, but lacked the technology or power output to create it until Enel came along with his lightning powers?

In conclusion:

1. I believe the Ark Maxim is a prototype version of the Ancient Weapon Uranus.
2. I believe Enel discovered the blueprints of Uranus and modified it so that he could use its power for himself.
3. I think that Uranus may have been developed, or perhaps entrusted, to the Birkans, who were unable to recreate it when their resources ran out.

*Theory by Beast of Rendall

In One Piece green databook it is written that Blackbeard was originally supposed to be so strong that he was even unbeatable by the three admirals.

The truth is, this statement is actually a misinterpretation.
In the original setting for BB’s power, Oda did make him very strong. In his early design, BB was unable to feel hot, cold, pain or even numbness. His only weakness was being unable to swim..

The Florian Triangle, (literally translated as Zone of Demonic Triangle) is a stretch of sea that one has to cross over when heading from Water 7 to Fishman Island. It is covered in a fog so thick that it blocks out all sunlight.

It has also been said that there are many haunted ships with dead bodies sailing across the sea

The Void Century is a century-long gap in recorded and archaeological history, the study of which is forbidden by the World Government. These events occurred 800 to 900 years before the current storyline. It was hinted at during the Skypiea arc; the dates were seen in Robin’s flashback.
