Deep beneath the land of Wano, in a forgotten chamber carved into the bones of the earth, Shamrock stood before the sealed colossus, the ancient weapon Pluton. This was no mere legend or dusty relic. It was a god-slaying machine from a time when kings feared knowledge more than steel. The chamber's walls were lined with fossilized circuitry and forgotten languages carved in obsidian, whispering of a time when the world was almost destroyed.
Pluton itself was an immense construct, part warship, part demonic altar. Rusted pipes hissed as long-sealed magic-tech reactors flared to life. Shamrock approached slowly, each step measured. His presence exuded control, his very breath bending the flow of time around him. With one motion of his hand, the chains of time were undone.
Time reversed in a localized sphere. Dust reassembled into bolts. Cracked steel returned to unblemished plating. The chamber lit with a haunting blue glow as power coursed through Pluton once more.
The prison cracked like a rotting chrysalis. The seals of ancient empires shattered, and the colossal weapon awakened with a tremble that echoed across tectonic plates. Its armored hull stretched hundreds of meters. A cannon of such magnitude that it could wipe civilizations in a single volley began to hum softly with awakened power.
Above ground, the land still smoldered from Shamrock's earlier conquest. The Flower Capital was ash. The mountains rang hollow. Amidst this devastation stood Vegapunk York, the traitor turned servant. The last surviving satellite of the genius scientist, now utterly broken by Shamrock's will and reshaped into a perfect tool.
Hovering through darkness propulsion, Shamrock presented two objects. One is a masterpiece of violence, the other a key to divine engineering. In his hand was the severed, still-conscious head of Franky, its memory-core intact, glowing with blue neuro-threading. Beside him, the awakened Pluton loomed like a sleeping titan.
"These," Shamrock said coldly, "are your template and your blueprint. The memory of its blueprints and the weapon itself. You have three years to construct ten."
York's greedy intellect flared. She bowed, suppressing awe. "With Franky's neural maps and this sample, I will deliver. Ten Plutons. No more, no less."
"Good," Shamrock said. "Because if you fail, I will erase your creation from the chain of causality. You will never have existed."
Without another word, he raised his hand. The air rippled, twisted and in a moment, a Temporal Stasis Sphere enveloped the entire island of Egghead. Inside, time would race at 1000x the normal rate. Outside, the island simply disappeared from the flow of history for a moment.
Within the sphere, York worked without pause. Laboratories of black iron rose from scorched earth. Robotic laborers stitched together hulls as tall as mountains. Energy reactors flared under moons that passed in seconds. Franky's neural data was fed into supercomputers. His consciousness screamed, used and dissected.
Each Pluton was not simply replicated. They were perfected. Faster recharging, heavier armor, modular targeting arrays. York, driven by Shamrock's looming threat, surpassed even her creator's limits.
The world outside remained unaware. Egghead Island was marked as a ruin, its skies sealed in silence.
Three years passed inside the bubble.
Outside? Only a breath.
With a snap of Shamrock's fingers, the stasis collapsed.
The skies split open, and ten metallic monsters floated silently above the ruins of the once-scientific island. Each Pluton hummed with deadly potential. Cannon ports opened like dragon jaws. Tectonic resonance stabilizers pulsed through their cores.
York stumbled from the central lab, her body enhanced but weary, her eyes sunken but victorious. She fell to her knees before Shamrock.
"They're complete… every line, every system… as you ordered."
Shamrock looked upon the fleet, his eyes cold, devoid of pride. "Good. These ten are not just weapons. They are to be the hand of the new God. They will end any rebellion before it begins."
As he stepped aboard the lead Pluton, now named as Cerberus Prime, he gave the order.
"Prepare the fleet. The final conquest begins."
It is time for Imu to step down from his everlasting throne.
