BOOM.
Lightning arced through the sky like a screaming god.
Clouds twisted in spirals of gold and blue as Upper Yard trembled beneath the force of Enel's judgment.
Smoke rose from the jungle canopy. Trees of cloudstone split apart. The very air crackled with voltage.
And in the middle of the storm…
Two figures stood.
Rex, coat fluttering, feet planted, one hand at his side glowing faintly with storm-chakra.
Enel, floating above the shrine, arms outstretched, a crown of current coiling above his head.
"YOU STAND BEFORE GOD," Enel roared, his voice splitting the air like thunder. "AND DARE TO DEFY HEAVEN?!"
Rex looked up, expression unreadable.
"I don't defy heaven," he said quietly.
"I'm what they sent to remind it of its mistakes."
Upper Yard – The Battlefield Forms
The Straw Hats stood on the outer steps of Enel's cloud throne, watching from the cliff's edge.
Zoro had his hand on his sword.
Sanji lit a fresh cigarette despite the wind.
Usopp hid behind Chopper, while Chopper hid behind a cloud bush.
Nami gripped the Den Den Mushi connected to Robin. "Are you seeing this?!"
Robin's voice echoed from the shell. "Yes. And I've read of something like it — old records from Birka, the sky city Enel came from. They spoke of a fallen warrior from the sky who was too powerful to name. They called him the 'Thunder Child.'"
Nami glanced at Rex.
"I think he's standing right there."
Rex Activates: Sky Pulse Mantle
As the first bolt came down, Rex didn't dodge.
He stepped into it.
Lightning struck his chest — and the moment it hit, the air exploded outward in a vortex of wind and crackling blue light.
The energy coiled around him, not burning, not searing — but merging.
[…Sky Pulse Mantle engaged. Voltage capacity increased. Dash unlocked: Cloud Phase.]…
The static clung to his shoulders like a second cloak.
Rex raised one hand, palm open.
"Let's go."
The Fight Begins – Rex vs. Enel (Phase One)
Enel grinned, body arcing with godly light.
He vanished in a flash — a thunderbolt slamming into the ground behind Rex.
Rex turned and countered instantly — a sharp arc of his arm formed a chakra disc, slicing through the energy field like a knife through silk.
Enel snarled.
"You can't touch me. I am lightning!"
Rex's eyes glowed.
"Then I'll move faster."
He clapped his hands together.
Poof.
Three Shadow Clones leapt into the air around Enel, scattering in formation.
One dived low. Another struck from the side.
The real Rex dropped down from above, Chidori humming in his palm.
ZRRRRRRRT.
He struck.
The bolt landed — Enel's shoulder exploded in sparks.
The god screamed in pain, electricity fracturing like glass from the impact point.
"You—!" Enel shouted. "You shouldn't—"
"Be able to touch you?" Rex said, landing smoothly.
"I don't need to believe in you to break you."
Enel Triggers: El Thor
The drums on Enel's back glowed.
"EL THOR!!!" he roared.
A column of divine lightning dropped from the heavens, obliterating the trees, cloud paths, and most of the jungle below.
The blast consumed the platform where Rex had just stood.
Smoke and wind whirled.
Silence.
Then—
A voice.
"Kame…"
Rex's form flashed out of the smoke — hovering mid-air, arms cupped to his side.
"Hame…"
The energy gathered — bright, building, a true cannon of blue and white light.
"HA!!"
BOOOOOM.
The beam shot straight through the lightning storm.
It collided with Enel's chest — launching him backward into his own shrine. The golden roof exploded. One of the drums shattered.
Rex landed smoothly on the platform, eyes narrowed.
"You're not the only one with light."
Cutaway: The Skyfolk Watch
From Angel Island to hidden bunkers in the forest, the Sky People watched.
Pagaya, the old mechanic, stood with trembling hands.
"That power… it's written in the archives…"
His daughter Aisa whispered, "Is he… is he a god too?"
"No," Pagaya said. "He's something different."
"He's a reminder."
Enel Awakens Phase Two – Amaru Form
Enel rose from the rubble, bleeding from his mouth, eye twitching.
"You… dare to scar divinity…"
He bit his thumb and drew a sigil across his chest.
The sky trembled.
Lightning twisted around his form until his body transformed — his torso lengthening, muscles cracking with light, his body expanding like a thunder-aspect.
Amaru.
A form no one in the Grand Line had ever seen — pure elemental power wrapped around flesh.
"I WILL ERASE YOU."
He vanished.
The lightning hit everywhere at once.
Rex Awakens: Bankai – Tensa
Rex closed his eyes.
And whispered—
"Bankai."
The air shattered.
A blade of blackened energy formed in his hand — sleek, sharp, and humming with storm-force.
He moved.
Faster than lightning.
Enel turned — but Rex was already beside him.
CLANG!
The blades met — thunder echoed across the sky.
The two flew into the air, colliding mid-strike, exchanging blows across the cloud-sea like falling stars.
Rasengan.
El Thor.
Chidori.
Amaru Slash.
The sky screamed.
Each strike turned cloud to vapor.
Each dodge bent the rules of gravity.
They weren't just fighting.
They were rewriting the storm.
Flashback Vision – The Betrayal of the Michaelers
As Rex clashed blades with Enel, a surge of memory slammed into him.
Not his.
But ancestral.
A vision carved into the thunder:
A city in the sky — golden and vast.
Winged warriors in spiraling armor.
A council of "gods" — Lunarian-like in appearance — sentencing a smaller group of storm-born warriors to exile.
"You were not made to rise above us."
"You used power meant only for the divine."
"You are not gods."
"You are Michaelers."
Rex's eyes opened mid-swing.
Now he remembered.
Final Clash – Lightning vs. Legacy
Rex leapt skyward, sword spinning, Rasengan forming in his free hand.
Enel screamed, pulling lightning into his own heart, forming a massive bolt of pure destruction.
"I AM LIGHTNING!"
Rex's voice cut through the wind.
"I AM THE STORM THAT CAME TO CORRECT YOU."
He threw the Rasengan.
It collided mid-air with Enel's bolt.
BOOOOOOOM.
The sky fractured.
A crack of power split the cloud sea in half.
Light blinded the island.
And when it cleared—
Rex stood alone on the shrine's broken floor.
Enel?
Gone.
Unconscious.
Defeated.
Stripped of thunder.
Aftermath – Echoes in the Sky
Luffy, Zoro, Sanji, and the rest ran up the ruined steps, panting.
"You… YOU WON?!" Usopp shouted.
Rex didn't answer.
He knelt beside the fallen Poneglyph under the shrine ruins.
And pressed a hand to the stone.
It pulsed once.
"Sky remembers sky.
The gods are not what they claim.
The world below must rise again."
Nami stood beside him.
"What's next?"
Rex stood slowly, eyes locked on the stars.
"We find the next glyph."
"And after that?"
Rex's voice was quiet.
"We find the one who made them."
