With the God of Rain making a dramatic appearance in the Elbaf Arc, One Piece fans worldwide are scrambling to understand what this ancient deity means for the story’s endgame. But what if the God of Rain isn’t a new concept at all — and what if Oda has been hiding a breathtaking structural pattern across every major arc of the entire series? If this theory is correct, the Final Saga isn’t just a conclusion: it’s the culmination of a divine war over the four fundamental forces of nature that has been quietly raging since Alabasta.
The Theory
Each major One Piece arc represents a struggle over one of the four ancient divine forces — Rain, Earth, Sun, and Forest — and the Final Saga’s Elbaf Arc will conclude with a battle over the Forest, centered on Mary Geoise.
The stakes here are enormous. This theory reframes the entire One Piece journey not as a series of disconnected adventures, but as a single mythological epic in which humanity has been fighting to reclaim stolen divine gifts — rain, land, sunlight, and forest — from those who hoarded them. The God of Rain appearing now in Elbaf isn’t a coincidence: it’s Oda completing the puzzle he laid out in Skypiea over two decades ago.
Evidence from the Manga
- Chapter 254–302 (Skypiea Arc): When Calgara’s daughter was offered as a sacrifice, she was given to four gods — the God of the Sun, God of Rain, God of Earth, and God of the Forest. This establishes that all four divine forces existed in the ancient world and were worshipped by humanity. The God of Rain is not new to Elbaf — he was named in Skypiea.
- Chapter 178–217 (Alabasta Arc): Crocodile’s entire scheme revolved around stealing rain from Alabasta. He used Baroque Works to trigger a civil war and suppress rainfall via Miss April Fools’ Day’s powers, leaving the country to die of thirst. When Vivi stopped the war, rain finally fell across the land. Alabasta’s conflict is, at its heart, a war over Rain.
- Chapter 490–653 (Fishman Island Arc): The Fishmen and Merpeople, forced to live on the ocean floor, desperately longed for the surface sun. Their history is defined by this yearning — which is precisely why Fisher Tiger’s Sun Pirates branded their members with the Sun symbol, turning a mark of slavery into a symbol of aspiration and freedom. The Fishman Island arc is a war over the Sun.
- Chapter 1106+ (Egghead/Elbaf transition): The God of Rain’s appearance in the current arc connects directly back to the four gods named in Skypiea. His presence signals that the “divine forces” framework is now entering its endgame phase, with Rain becoming a central narrative element once again.
📌 Key Evidence: In the Skypiea Arc, the central conflict is the Shandians’ 400-year battle to reclaim their homeland — the earth beneath the sky island. Enel, who sought to reach the “Fairy Vearth” (solid land), represents the divine appropriation of Earth itself. Both sides of the Skypiea war — Shandians and Skypeians alike — were fighting over land that was violently stolen from them. This arc is a war over Earth.
| Arc | Divine Force | Who Was Deprived | Symbol of Longing |
|---|---|---|---|
| Alabasta | Rain 🌧️ | The people of Alabasta | Vivi’s prayer; Nanohana’s desert |
| Skypiea | Earth 🌍 | Shandians / Skypeians | Fairy Vearth; Calgara’s homeland |
| Fishman Island | Sun ☀️ | Fishmen and Merpeople | Sun Pirates; Fish-Man Island’s light |
| Elbaf / Final Saga | Forest 🌲 | ??? | Mary Geoise? |
📌 Key Evidence: Mary Geoise — the seat of the World Government and the Celestial Dragons — sits atop the Red Line and is notably described as having a lush, paradisiacal environment. It is one of the few places in the One Piece world with abundant greenery. If the Forest is the final divine force to be “liberated,” Mary Geoise is the only location in the story that fits the profile of a place where the Forest is being monopolized by those in power.
Our Analysis
What makes this theory particularly elegant is that it recontextualizes Oda’s thematic DNA across the entire series. Oda has always embedded his arcs with elemental symbolism — water, sky, ocean floor, nature — but framing those elements as stolen divine forces transforms the Straw Hats’ journey into something almost mythological: a crew of mortals unwittingly restoring the four pillars of nature to the world. Luffy didn’t just defeat Crocodile; he returned rain to a dying nation. He didn’t just beat Enel; he gave the Shandians back their earth. The pattern is too deliberate to be accidental.
The Forest angle for the finale is the most compelling and underexplored part of this theory. Mary Geoise’s suspiciously verdant environment — amid a world of oceans, deserts, and undersea kingdoms — has always felt narratively incongruous. If the Celestial Dragons have been hoarding the “Forest,” this would give the final conflict a thematic weight that goes far beyond political revolution. It would mean Luffy’s assault on Mary Geoise is, mythologically speaking, humanity reclaiming the last stolen gift of the gods. That is a finale worthy of the series’ scope.
Counter-evidence worth acknowledging: Wano and Whole Cake Island don’t fit neatly into this framework, which suggests Oda may not have designed every arc around this pattern — or that these four arcs were specifically chosen as the “divine pillars” while others serve different narrative functions. Still, the fact that Rain, Earth, and Sun align so precisely with Alabasta, Skypiea, and Fishman Island — three of the most thematically rich arcs in the series — makes it very difficult to dismiss this as coincidence.
Theory Credibility Rating
Based on manga evidence and foreshadowing
The three confirmed data points — Alabasta/Rain, Skypiea/Earth, Fishman Island/Sun — are rock-solid, and the Skypiea sacrifice scene explicitly naming all four gods provides direct textual anchoring; the only uncertainty is whether Oda will fully execute the Forest/Mary Geoise payoff in the Final Saga, which keeps this just short of a perfect score.
