Four Gods Theory: Every Arc Has a Divine Element

With the Rain God making a dramatic appearance in the Elbaf Arc, longtime fans are scrambling to connect the dots — but one Japanese theorist argues the clues have been hiding in plain sight since the Skypiea Arc. If this theory is correct, every major arc in One Piece isn’t just a standalone adventure: it’s one chapter of a cosmic war over the four divine elements, and the Final Saga is heading straight for the last one.

The Theory

The stakes here are enormous. This theory doesn’t just explain past arcs thematically — it predicts the shape of the endgame. Oda has been quietly building a divine elemental framework since the earliest days of the Grand Line, and the recent reveal of the Rain God in the Elbaf Arc may be the moment the entire pattern snaps into focus. If the four gods of Skypiea’s ancient sacrificial religion map directly onto One Piece’s major storylines, then the Final Saga isn’t just about the World Government — it’s about restoring something primordial to the world itself.

Evidence from the Manga

1. Chapter 254–302 (Skypiea Arc): When Gan Fall’s backstory and the ancient Shandian rituals are explored, we learn that the people of Skypiea once made sacrifices to four gods: the God of Sun, the God of Rain, the God of Earth, and the God of Forest. This is not decorative world-building — Oda named all four explicitly. Kalgara’s daughter was offered as a sacrifice to appease these divine forces, confirming they were treated as real, active powers in the world’s ancient history.
2. Chapter 167–217 (Alabasta Arc): The central conflict of Alabasta revolves entirely around rain. Crocodile used his Devil Fruit to steal Alabasta’s rainfall, turning a once-fertile kingdom into a dying desert. The citizens prayed desperately for rain. When Vivi stopped the civil war, it was rain — falling all at once across the kingdom — that signaled the end of the conflict. Rain was not just a backdrop; it was the prize, the wound, and the healing.
3. Chapter 490–513 (Sabaody & Fishman Island setup) / Chapters 610–653 (Fishman Island Arc): The people of Fishman Island have lived in the ocean depths, cut off from sunlight for generations. Their longing for the surface — for the Sun — defines their entire cultural and political identity. The Sun Pirates take their name from this yearning. The Sun symbol appears on the slave brand reclaimed as a mark of liberation. Fisher Tiger’s rebellion and Jinbe’s arc are, at their core, a battle over access to sunlight — the fight of a people for the Sun God’s gift.
4. Current Elbaf Arc (post-Chapter 1100s): The Rain God has now appeared as an active entity in the story for the first time since being named in Skypiea. This is the trigger for the entire theory — Oda is returning to the four-god framework after leaving it dormant for hundreds of chapters, suggesting the divine elements are becoming plot-critical in the Final Saga.

📌 Key Evidence: In the Skypiea Arc, four gods are explicitly named in the context of ancient sacrifice: Sun, Rain, Earth, and Forest. Alabasta = Rain stolen and reclaimed. Skypiea = Earth stolen and reclaimed (Shandians lost their land to the sky invaders; Enel sought to reach the “Blue Sea” / terrestrial land). Fishman Island = Sun longed for and symbolically reclaimed. That leaves Forest — and no major arc has claimed it yet.

📌 Key Evidence: The Skypiea conflict is framed explicitly as a battle over land — the Shandians were expelled from their ancestral earth by the sky island’s rise 400 years ago. Enel, meanwhile, planned to leave Skypiea to reach the “Blue Sea” — solid ground. Every faction in Skypiea was oriented around the desire for Earth. This perfectly mirrors how Alabasta’s every faction was oriented around Rain.

Our Analysis

What makes this theory particularly compelling is that it reframes Oda’s arc structure not as a collection of individual pirate adventures, but as a single mythological epic told in movements. Oda is known for layering thematic resonance decades in advance — the Void Century, Joy Boy, the Will of D — and a four-element divine framework operating quietly beneath the surface of the Grand Line journey fits his authorial fingerprint perfectly. The fact that the Rain God went unnamed and unseen for hundreds of chapters before reappearing now, in the Final Saga, suggests Oda never forgot that list of four gods from Skypiea. He was saving it.

The Forest God is the missing piece — and the theory’s most exciting implication is its proposed location: Marijoa. Mary Geoise, the seat of the World Government and home of the Celestial Dragons, sits atop the Red Line. Notably, it is described as having an unnaturally lush environment at an altitude that should make vegetation impossible. There is a mysterious forest or garden referenced in connection with Marijoa’s interior. If the World Government has literally captured or is drawing power from the Forest God — the last of the four divine elements — then the Final War isn’t just political. It’s a war to return the last stolen piece of the natural world to humanity.

A potential counterargument is that the arc-element mapping requires some interpretive flexibility — Skypiea is thematically about land, yes, but it’s also about religion, heritage, and gold. Similarly, Fishman Island covers discrimination and history as much as sunlight. However, this doesn’t weaken the theory so much as show that Oda layers meaning: the elemental theme is the mythological skeleton, while the human drama is the flesh over it. The Rain God’s re-emergence in Elbaf is the signal that the skeleton is about to be made visible.

Theory Credibility Rating

The four-god framework is grounded in explicitly named canon lore from Skypiea, the thematic parallels across three arcs are remarkably clean, and the Rain God’s return in the Final Saga gives the theory urgent new relevance — the only missing piece is confirmation of what the Forest arc will look like, which is why it falls just short of five stars.
