The Red Line's Role
In the vast world of One Piece, the Red Line is a massive, continent-sized ring of land that circles the entire globe. Stretching from the sky down to the ocean floor, it acts as a physical barrier that divides the world's oceans into the East Blue, West Blue, North Blue, and South Blue. For centuries, the One Piece Red Line has served as the ultimate symbol of separation and control. At its highest peak lies Mariejois, the capital of the World Government and the home of the Celestial Dragons. By controlling the only points of passage through the Red Line—Reverse Mountain and Fish-Man Island—the World Government maintains its iron grip over global travel and trade. This geographical dominance is why many fans believe the destruction of the wall is necessary for true freedom to exist.
Pluton's Purpose
The Red Line destruction theory often centers on the Ancient Weapons, specifically Pluton. Described as a massive warship capable of destroying entire islands in a single shot, Pluton's true power has been a mystery for most of the series. During the Wano Country arc, it was revealed that Pluton is hidden beneath the depths of old Wano. If Luffy or his allies were to awaken this weapon, its primary purpose might not be conquest, but rather the literal reshaping of the world. Utilizing such immense firepower would be the most logical way to breach the seemingly indestructible Red Line, effectively removing the walls that keep the world divided. Many theorists suggest that the "dawn of the world" requires the removal of the very structures that the World Government uses to stay in power.
Fish-Man Island Prophecy
One of the most compelling pieces of evidence for this theory is the prophecy delivered by Madame Shyarly during the Fish-Man Island arc. She predicted that Monkey D. Luffy would one day destroy Fish-Man Island. While this initially seemed like a dark omen, the Red Line destruction theory reinterprets this as a necessary step toward liberation. Fish-Man Island is located directly beneath the Red Line at the Holy Land of Mariejois. If Luffy were to destroy the Red Line above, Fish-Man Island would inevitably be crushed by the debris. However, with the help of the Ancient Weapon Poseidon (Shirahoshi) and the massive ship Noah, the Fish-Men could be evacuated to the surface. This would fulfill the ancient promise of Joy Boy, allowing the Fish-Men to live under the real sun while the physical barrier separating the seas is obliterated.
All Blue Connection
Sanji’s dream is to find the All Blue, a legendary sea where fish from all four oceans coexist. Throughout the series, the existence of the All Blue has been treated as a myth because the Red Line and the Calm Belt physically prevent the four seas from mixing. However, if the Red Line were to be destroyed at the intersection of Reverse Mountain and Mariejois, the barriers would vanish. This catastrophic yet transformative event would result in all seas united into one singular ocean. In this new world, every species of fish would be able to swim freely across the globe, making Sanji's dream a reality. The creation of the All Blue is not just a culinary achievement but a geographical consequence of the world finally being "in one piece."
Supporting Evidence
The narrative of One Piece has consistently focused on the theme of "Inherited Will" and the eventual collapse of the current world order. Several clues support the idea of the Red Line’s demise:
- The Name of the Series: The title "One Piece" may refer to the world itself being returned to "one piece" after the Red Line is destroyed.
- Joy Boy’s Apology: Joy Boy’s apology to the past Mermaid Princess suggests he failed to move the Fish-Men to the surface, a task Luffy is expected to complete.
- The World Government’s Fear: The Five Elders and Imu are obsessed with maintaining the "balance" of the world, which the destruction of the Red Line would permanently shatter.
- Luffy’s Dream: While Luffy wants to be the Pirate King, his true, hidden dream likely involves a world where everyone can be free, which is impossible with the current restricted geography.
