After their victory, the kings created a formal governmental organization known as the World Government and their descendants went on to become the Celestial Dragons, also called the World Nobles, who wield tremendous political influence in the present day.

Over the centuries, the authority and reach of the World Government expanded drastically.

At the current point in the One Piece story, more than 170 nations are allied with or under the jurisdiction of the World Government.

To enforce its laws and maintain control across the globe, the World Government utilizes its military wing known as the Marines, as well as the Warlords of the Sea.

With its vast military and political influence, the World Government effectively dominates most affairs of the One Piece world.

Several key figures and groups yield enormous power in upholding the World Government’s regime. The Celestial Dragons retain wealth, privileges, and political clout beyond that of any royal dynasty.

Among the ruling body itself, a council of elders known as the Five Elders called the Gorosei, formed the highest governing authority and influenced global policy.

Yet above even the Gorosei stands the mysterious Im, who resides in the Holy Land of Mariejois and holds a supreme, almost godlike position within the World Government power structure.

Through this rigid hierarchy of power and far-reaching rule, the World Government regime asserts its authority over the seas, islands, and civilizations across the sprawling world depicted in One Piece.

The Secret Authority Behind the Empty Throne and the World Government’s Hidden Leader

Imu was first unveiled during the Reverie storyline arc in One Piece, which picks up right after the events on Whole Cake Island.

As rulers and royalty from nations affiliated with the World Government gathered for the Reverie council, which was held every four years, author Eiichiro Oda provided deeper insight into the World Government’s power structure and inner workings.

The story reveals the existence of an iconic seat known as the Empty Throne, located at the center of the World Government’s holy land of Mariejois.

This throne is meant to symbolize equality among the allied nations of the World Government, and it seemingly sits vacant as a representation of no single country holding a higher status.

However, this is merely an illusion fabricated by the World Government. In truth, the Empty Throne is covertly occupied by none other than the mysterious figure of Imu, who serves as the enigmatic supreme leader.

So, while the weapons of the past kings stand guard around it to reinforce the idea of equivalence, the Empty Throne is actually a seat of supreme authority for the commanding yet unseen ruler Imu.

Keeping even the existence of Imu extremely confidential, the World Government leverages symbols like the Empty Throne to present the allied nations as peers, while Imu retains absolute rule from the shadows as the decisive sovereign in their pyramid of power.

Through this pivotal revelation in the Reverie storyline, Eiichiro Oda peeled back the curtain on Imu’s central, albeit discreet, position over the World Government itself as well as the entire One Piece world.

Imu’s Supreme Authority, Enigmatic Power, and Potential Role as One Piece’s Central Antagonist

While creator Eiichiro Oda has kept most details about the enigmatic Imu tightly under wraps, his brief appearances provide critical insights.

As the covert figure who occupies the Empty Throne, Imu clearly acts as the supreme ruler and wields the pinnacle of power within the World Government structure.

One Piece (Credits: Eiichiro Oda)

This is evidenced by the fact that even the Gorosei, the highest governing public authority, bow before Imu and await his commands when reporting on high-priority global affairs.

So despite the World Government’s outward presentation of equivalent status among its allied nations, Imu alone holds supreme authority over its inner workings and major decisions.

Though his combat abilities remain unknown, Imu is depicted wielding a saber, which he ceremoniously uses to stab an image of Princess Shirahoshi.

In the same scene, he sliced up the wanted posters of Monkey D. Luffy and Marshall D. Teach, better known as Blackbeard, hinting at intriguing connections yet to be revealed in the One Piece storyline.

Given his shadowy yet absolute control over the World Government itself and his shaping of pivotal events from behind the curtain, Imu is most likely the central antagonist of the entire One Piece saga.

While details remain scarce, his presence at the peak of power and intersection with fateful characters position Imu as arguably the biggest villain lurking in the world of One Piece.

Imu’s Role in One Piece’s Final Saga, Immortality Speculations, and Ominous Foreshadowing

Given the timing and manner of his introduction, it is evident that author Eiichiro Oda has major plans for Imu in the final saga of One Piece.

As the current hidden King of the World Government, Imu already wields unmatched global power and influence from the shadows.

Furthermore, subtle hints indicate Imu may have an extraordinarily extended lifespan or even immortality, fueling theories that he could be a living relic from the mysterious Void Century, 800 years in the One Piece world’s past.

Some fans speculate Imu may have attained eternal youth via the Perennial Youth Surgery administered by a previous user of the Ope Ope no Mi Devil Fruit.

While mere speculation for now, this would perfectly position Imu as an all-powerful puppet master who has shaped history from behind the scenes for centuries.

As the story heads toward its climax, Imu has already begun making calculated moves from his seat on the Empty Throne.

At the close of the Reverie meeting, Imu directs the Gorosei to eliminate a particular threat, then ominously clutches an image of Princess Vivi of Alabasta Kingdom.

This foreshadows catastrophic events to befall Alabasta and Vivi herself soon after, suggesting Imu deliberately orchestrated an attack on her homeland.

With the final saga approaching, it is clear the supreme ruler Imu will step out of the darkness he has dwelled in for so long to bring his full power and influence to bear, making him undoubtedly one of the final villains to face the Straw Hats and their allies in their quest for the One Piece treasure.

Imu’s Unveiling as the True Antagonist Sets the Stage for Luffy’s Ultimate Showdown

At this pivotal point in the One Piece story, the central protagonist, Luffy, and his Straw Hat crew are engrossed in liberating Wano Country from the grip of Emperor Kaido and the Beast Pirates.

Meanwhile, unbeknownst to them, seismic shifts are happening across the wider world, masterminded by none other than the enigmatic Imu from his Empty Throne.

Once Wano’s borders finally open and word spreads of Imu’s maneuvers during the recent Reverie, the gravity of events will likely bring Luffy’s ultimate clash with the World Government to a head.

As Whitebeard and Kozuki Oden once foretold, a great war dwarfing the scale and stakes of Marineford will erupt. With Luffy’s ascent as the future Pirate King and discovery of the True History, this fated war with Imu and the World Government looms imminent.

Given the supreme authority he wields from the shadows, Imu will undoubtedly step forth as the principal antagonist when the final saga reaches its crescendo.

With Luffy and his allies challenging the global order, Imu and his forces will aim to ruthlessly quash this threat to his ironclad rule.

When the Great War ignites across the One Piece world, all of Imu’s secrets, motivations, and endgame will be thrust into the spotlight through his climatic clash against Luffy’s alliance.

Though the road ahead remains arduous, this ultimate showdown with Imu represents Luffy’s destined fight to usher in a new dawn.

The Empty Throne’s Enigmatic Ruler

While the full extent of Imu’s strengths remains a mystery, context clues denote his unrivaled supremacy within the One Piece world order.

As the one seated on the Empty Throne, an iconic seat historically associated with sole sovereign authority over the entire world, Imu clearly holds preeminent status.

One Piece (Credits: Eiichiro Oda)

This is further evidenced by the fact that Gorosei, the highest public-facing governing body, bowed to Imu and addressed him using the utmost honorifics.

Despite wielding such phenomenal power, Imu appears limited by an inability to assert his authority directly in public. Instead, he rules by proxy, covertly directing the Gorosei to orchestrate his will.

A prime example is Imu’s ability to instantly deploy the apocalyptic weapon, Mother Flame. Created by scientific genius Dr. Vegapunk, this weapon can completely annihilate an entire island within seconds when deployed.

The fact that Imu can trigger such instant mass destruction again shows that his word is absolute despite his enigmatic identity.

So, while specifics remain undisclosed, existing signs unambiguously establish Imu as the One Piece world’s supreme figure who has commanded history from the Empty Throne for centuries.

With the Great War looming, his capabilities as a warrior and leader will likely soon match his already unparalleled political clout at the apex of the World Government pyramid.
