Who is Imu? The Secret Ruler Sitting on the Empty Throne
For 800 years, the World Government claimed that the "Empty Throne" in Mary Geoise was a symbol of peace—proof that no single person rules the world.
They lied.
During the Reverie and the Sabo flashbacks, we learned the terrifying truth: There is a King of the World, and their name is Imu (or Im-sama). Even the Five Elders (Gorosei), the highest public authority, bow down in fear before this mysterious figure.

The Power to Erase Islands (Mother Flame)
Imu’s power is terrifying not just because of political influence, but because of pure destructive capability. We witnessed the Lulusia Kingdom vanish in seconds, erased by beams of light from the sky.
- The Weapon: It is heavily implied that Imu controls an Ancient Weapon (likely Uranus) powered by Dr. Vegapunk's "Mother Flame."
- The Devil Fruit: When Sabo attacked the throne room, Imu transformed into a massive, beast-like creature (possibly a shadowy dragon or a devil entity) capable of swallowing fire.
The Connection to Nefertari Lily
The most recent manga chapters revealed a shocking connection to Alabasta. Imu seemingly knew Queen Lily Nefertari from the Void Century (800 years ago). This suggests Imu is immortal, likely having received the "Perennial Youth Operation" from the Ope Ope no Mi (Law's fruit) centuries ago. Imu views the current era’s pirates not as people, but as "insects" to be crushed.
Is Imu the Final Boss for Luffy?
While Blackbeard represents the "Pirate" rival, Imu represents the ultimate oppression of the World Government. Luffy, the embodiment of freedom (Nika), is destined to clash with Imu, the embodiment of control. This fight will likely determine the freedom of the entire world.
Conclusion: The End Game
The existence of Imu changes everything. The Marines are just pawns. The real enemy is hiding in the shadows of the Red Line.
Prepare your crew for the ultimate war against the World Government in the MMORPG MyLegend.
