The Three Ancient Weapons of One Piece
One Piece features three legendary Ancient Weapons: Pluton, Poseidon, and Uranus. Their names come directly from Greek mythology, but their deeper inspirations span multiple ancient civilizations.
1. Greek Mythology — The Origin of the Names
Uranus (Οὐρανός) is the primordial Greek god of the sky — the first ruler of the cosmos, father of the Titans, grandfather of the Olympians.
Poseidon is the Olympian god of the sea, earthquakes, and horses. In One Piece, Poseidon is Shirahoshi — a mermaid princess capable of communicating with Sea Kings. The parallel to a sea deity is obvious.
Pluto (the Roman equivalent of Hades) is the god of the underworld and the dead. Pluton in One Piece is described as a ship capable of destroying entire islands — destruction on a godly scale.
2. Hindu / Vedic Mythology — The Vimana
Ancient Indian sacred texts, including the Vedas and the epics Ramayana and Mahabharata, describe flying weapons called Vimana — divine aerial vehicles capable of mass destruction.
The Pushpaka Ratha, a celestial flying chariot used by Ravana in the Ramayana, is the closest mythological parallel to Pluton: a massive flying warship built by the gods, capable of carrying armies and raining destruction.
3. Norse Mythology — Ragnarok-Level Weapons
Norse mythology describes weapons with apocalyptic power: Gungnir (Odin’s spear that never misses), the hammer Mjolnir (Thor’s world-shaking weapon), and the ship Naglfar (built from dead men’s nails, crewed by the forces of Ragnarok).
Naglfar in particular — an enormous ship associated with the end of the world — resonates with Pluton as a catastrophic naval weapon.
4. Aztec Mythology — The Sun God Nika
The Aztec sun god Tonatiuh required sacrificial blood to continue rising each day. The connection to Nika, the “Sun God” in One Piece whose power brings liberation and joy, suggests Oda drew from multiple solar deity traditions.
Uranus, as an as-yet-unrevealed weapon, may have strong connections to solar or sky-deity mythology.
5. Zoroastrian / Iranian Mythology — The Final Layer
Ancient Iranian religion (Zoroastrianism) describes a cosmic battle between Ahura Mazda (truth, light, order) and Angra Mainyu (chaos, darkness, destruction). This duality — the force of liberation versus the force of oppression — mirrors the central conflict of One Piece perfectly.
The ancient weapons may represent both sides of this duality: instruments of the ancient kingdom’s truth, versus the tools of oppression wielded by the World Government.
Conclusion
The three ancient weapons in One Piece are not merely Greek references — they draw from a global mythology of divine weapons of creation and destruction. Understanding these layers adds profound depth to One Piece’s worldbuilding and foreshadows the ultimate conflict that will determine the fate of the world.
