The Secret Behind Lulusia’s Destruction: Imu-Sama, Uranus, and the Mother Flame

 

The Imu-Sama & Ancient Weapon Connection: How One Piece Is Setting Up Its Final War

The climax of One Piece is accelerating toward an all-out global war. With the revelations surrounding the Void Century, Dr. Vegapunk’s worldwide broadcast, and the aerial destruction of the Lulusia Kingdom, Eiichiro Oda has provided the key missing link to the ancient world: how the World Government intends to wage its final war.

At the center of this looming global catastrophe sits Imu-Sama, the sovereign of the Empty Throne, and an insidious connection between the Ancient Weapon Uranus and Vegapunk's artificial energy creation, the Mother Flame.

1. Who is Imu-Sama? The Immortal Ruler of the Void Century

For centuries, the World Government maintained the public illusion that the Empty Throne in Pangaea Castle remained vacant to symbolize absolute equality among its founding kingdoms. However, the introduction of Imu-Sama shattered that foundational myth.

• The First Twenty Connection: Emperor Ivankov theorized that Imu belongs to the Nerona Dynasty—one of the original twenty monarchs who formed the World Government 800 years ago during the Void Century.
• Perpetual Youth Vow: It is heavily implied that Imu underwent the Ope Ope no Mi’s Eternal Youth Operation, granting them immortality that has spanned over eight centuries.
• Absolute Authority: The Five Elders (Gorosei) bow directly to Imu, executing horrific "Great Cleansing" orders that wipe entire nations off the map with zero public oversight.

2. The First Twenty's Arsenal: The Holy Knights and Relic Weapons

Recent events in the Elbaf Arc revealed that Imu's reign is not maintained merely through political authority or standard Haki, but through direct manipulation of ancient legacy weapons via the God’s Knights (Holy Knights).

During the invasion of Elbaf, Holy Knights like Sommers and Killingham were seen wielding specialized, legendary weapons—such as the broadsword Gram (belonging to the Shepherd Family) and the holy spear Longinus (belonging to the Rimoshifu Family).

Imu manifests these weapons using a dark power known as Omen, bestowing the original armaments of the First Twenty directly to top enforcers. This confirms that the founding families did not just leave swords in front of the Empty Throne as a pledge of peace; those weapons were active tools of conquest preserved to suppress rebellions across generations.

3. The Mother Flame: The Missing Spark for Destruction

For decades, the existence of the three Ancient Weapons—Pluton, Poseidon, and Uranus—was shrouded in mystery. While Poseidon is Shirahoshi's inherited mermaid ability and Pluton remains buried beneath the walls of Wano Country, Uranus remained completely unverified until the sudden obliteration of the Lulusia Kingdom.

Dr. Vegapunk developed the Mother Flame inside the Fusion Reactor on Egghead Island, intending it to serve as an infinite, clean energy source for the entire world. However, the rogue satellite York secretly stole a small fragment of this power source and supplied it directly to the World Government.

Key Takeaway: The Mother Flame itself is not a weapon; it is the power source required to activate ancient high-technology.

Without a self-sustaining power source like the Mother Flame, the World Government possessed the physical structure of Uranus for hundreds of years, but lacked the raw energy required to charge its destructive light beam array.

4. Lulusia’s Destruction and the Rising Sea Levels

When Imu ordered the test run on the Lulusia Kingdom, a giant flying construct hidden above the clouds rained down sixteen concentrated beams of light, erasing the island from existence in a matter of seconds.

1. Immediate Total Erasure: Lulusia was wiped off physical maps, leaving behind a massive, bottomless ocean hole identical to the one at Enies Lobby.
2. Global Cataclysm: The usage of the Mother Flame-powered weapon triggered massive earthquakes, causing world sea levels to permanently rise by one meter overnight.
3. The Sinking World Truth: Vegapunk’s worldwide broadcast confirmed that during the original Void Century war, sea levels rose by 200 meters. This proves that the ancient conflict 800 years ago was fought using these exact same superweapons powered by ancient energy.

5. Major Manga Developments: The "King of the World" and Elbaf

The Elbaf Arc has dramatically expanded the lore regarding Imu's true standing and historical reach. Key revelations from the latest manga chapters include:

• Shanks' Warning to Prince Loki: Flashbacks reveal that "Red-Haired" Shanks met with Prince Loki of Elbaf and explicitly warned him about the "King of the World" hiding behind the Gorosei. Shanks noted that Imu's power is beyond measure and that attempting a direct, uncalculated strike would lead to immediate destruction.
• Imu Descends on Elbaf: Imu personally manifested in Elbaf, utilizing dark weaponry—including the vitality-draining blade Fragarach—to overpower both Prince Loki and Monkey D. Luffy, pinning Luffy to Yggdrasil before the arrival of Scopper Gaban.
• The War for Elbaf's Sovereignty: Elder Jarul explained to Hajrudin that the World Government’s sudden invasion of Elbaf was not a decision voted on by the Levely, but a personal directive from Imu to subjugate the giants and secure their ancient knowledge.

6. Popular Fan Theories: What Comes Next?

With the narrative entering its most intense phase, the One Piece community has put forward several major theories:

Theory A: Luffy’s Yggdrasil Awakening (The Norse Odin Connection)

In Norse mythology, Odin hung himself on the cosmic tree Yggdrasil for nine days to gain ultimate wisdom. Following Luffy being pinned to the giant tree in Elbaf by Imu’s weapon, fans theorize Luffy will undergo a mental or Haki awakening while immobilized, gaining a deeper understanding of the Void Century or the origin of Devil Fruits before breaking free.

Theory B: The Sun God Nika vs. The Artificial Sun

Vegapunk created the Mother Flame as a synthetic "sun" energy source. Because Luffy represents Sun God Nika, theories suggest that Luffy’s true Gear 5 capabilities will allow him to absorb or neutralize the Mother Flame's energy, rendering Uranus completely unpowered once again.

7. The World Government’s Ultimate Weapon Strategy

The World Government's long-term survival relies on absolute control over historical information and physical resources. By securing York and the Mother Flame manufacturing infrastructure, Imu solves a century-old problem:

• Infinite Fuel for Uranus: With continuous access to the Fusion Reactor's production capabilities, Imu can fire Uranus at will without waiting centuries to recharge.
• Controlled Deluge: By selectively target-destroying rebellious nations, the World Government can deliberately raise global sea levels to submerge islands, drowning revolutionary bases while keeping Mary Geoise safe atop the high-altitude Red Line.
• Resource Dominance: Nations that lack high-elevation territory will be forced to submit completely to World Government protection, consolidating Imu’s rule.

8. The Revolutionary Army’s Counter-Strategy

Now that Sabo witnessed Imu on the Empty Throne and Dragon understands the true nature of the Lulusia incident, the Revolutionary Army has shifted its strategic priorities:

• Targeting Supply Lines: Instead of attacking Mary Geoise head-on, Dragon's forces are cutting off shipping routes and food supplies to the Holy Land.
• Preventing Fuel Delivery: Halting the transport of the Mother Flame from Egghead or future manufacturing sites directly neutralizes Uranus' capability to fire again.
• Exposing the Truth: Spreading the reality of the Void Century prevents the World Government from framing island destructions as natural disasters or God's wrath.

9. The Final War Roadmap: World Government vs. Sun God Nika

As Luffy fully embraces his Gear 5 awakening as Joy Boy, the narrative sets up an inevitability: a direct clash between the ancient weapon of destruction (Uranus) and the warrior of liberation who brings the dawn to the world.

• Imu’s Goal: Use Uranus and the Mother Flame to flood the world, extinguish the Will of D., and freeze society in a perpetual state of censorship and stagnation.
• Luffy’s Path: Unite the remaining Ancient Weapons—Poseidon (Shirahoshi) and Pluton (once Wano's borders open)—to counter Uranus and tear down the Red Line, restoring freedom to the seas.
