In a distant corner of the cosmos, far beyond the reach of ordinary civilizations, a lone planet burned under siege.
Countless warships darkened its skies, their weapons raining destruction upon the surface. Swarms of monstrous entities poured forth from the void—soldiers of the Antimatter Legion, relentless and merciless.
The world was moments from annihilation.
Then—
A streak tore through space.
It moved faster than light itself, a blur so absolute that even starlight seemed frozen in its wake.
From the void descended a warrior.
A humanoid figure clad in mechanical armor, bearing the form of an insect—sleek, sharp, and unstoppable.
Kamen Rider Zero-Three.
Without hesitation, Zero-Three surged forward.
He crashed into the Legion's fleet like a living comet.
Warships exploded in chains of fire as he tore through them, one after another. Legion monsters rushed him in endless waves—
Voidranger: Reavers.Voidranger: Distorters.Voidranger: Eliminators.Voidranger: Tramplers.
None could even slow him down.
Even the colossal Doomsday Beast met its end—ripped apart in mere moments, its massive form reduced to drifting fragments in the vacuum of space.
Silence fell.
Only debris remained, floating like dust in the stars.
Zero-Three hovered in the aftermath, his gaze scanning the battlefield.
Then—
A presence.
He turned.
And saw him.
A man stood in the void.
His body was black and white, wrapped loosely in strips of white cloth that drifted like weightless fabric. His clawed fingers gripped a long, thin black blade. Behind him, five metallic rectangles floated in formation, extending like a fractured wing.
Zephyro.
Without a word, Zero-Three flicked his wrist and pressed the Progrisekey on his driver.
"Blade On Big Bang."
In a flash of energy, the Thousand Jacker materialized in his grasp.
Zephyro moved first.
His blade sliced through space itself, distorting reality as he struck—but Zero-Three met him head-on.
Their clash shattered the void.
Black and white distortions collided with blazing energy as the two exchanged blows at incomprehensible speeds. Each strike warped space, each impact echoed like thunder across the stars.
But as the battle raged on—
Something changed.
"LEARNING COMPLETE."
Zero-Three's voice rang out.
Every movement. Every distortion. Every technique Zephyro used—
Was being analyzed.
Copied.
Perfected.
Zero-Three began to overwhelm him.
Zephyro created a White Hole, a collapsing sphere of warped space meant to erase everything in its path.
But Zero-Three raised his weapon.
And mirrored it.
A second White Hole formed—perfect, identical.
The two forces collided.
Reality twisted violently before collapsing in on itself, the shockwave tearing through the battlefield.
Zephyro staggered—
Before the final blow could land—
He vanished.
Teleported away at the last possible moment.
Silence returned once more.
Zero-Three lowered his weapon, scanning the emptiness.
Then—
Another presence.
Heavier.
Colder.
Divine.
Zero-Three looked up.
Space itself fractured—
Like shattered glass.
And beyond it—
A being gazed down upon him.
A man with long white braided hair, golden eyes burning with quiet destruction. His brown skin was marred with wounds, golden ichor flowing from them like divine blood. His body seemed incomplete—parts of his arms floated apart, revealing radiant energy within. Golden flames and black smoke consumed half of his lower form.
Nanook.
The Aeon of Destruction.
Their eyes met.
"LEARNING COMPLETE."
Zero-Three pressed his Progrisekey once more.
"DESTRUCTION ON BIG BANG."
Golden energy surged into his hands—power mimicking the very essence of destruction itself.
He fired.
The blast tore through space.
Even Nanook reacted.
The Aeon shifted—barely avoiding the attack.
But not completely.
The edge of the blast grazed him.
A wound formed on his shoulder.
Golden ichor spilled.
For a brief moment—
Silence.
Nanook stared at Zero-Three.
Then—
Space sealed.
The fracture closed.
And the Aeon vanished.
The battlefield was quiet once more.
Zero-Three remained floating in the void, surrounded by remnants of war and fading energy.
He exhaled softly.
"…Where are you, Welt?"
