The remnants of the Universal Space Domain were eerily still, a breathless void stretching infinitely. Kael and the Demon King stood in their colossal dragon forms, their wounds instantly healing as if nothing had transpired. The stars reappeared, and the fractured galaxies repaired themselves in a cosmic rewind, resetting the stage for the next battle.
The Demon King's crimson eyes glowed with intensity as he chuckled darkly. "Enough games, Kael. Let's get serious now."
Kael's golden scales shimmered, his divine aura pulsating. "Serious? I thought you already were. Don't disappoint me now."

The Legion of Shadows
The Demon King grinned, raising his massive claw. Shadows began to writhe and multiply, forming endless duplicates of his enormous form. Millions of dark copies now surrounded Kael, each radiating malevolent energy.
"How do you like this?" the Demon King roared.
The duplicate dragons opened their mouths, each forming a massive sphere of black energy. The void trembled as millions of red beams erupted simultaneously, converging toward Kael with cataclysmic force.
Kael's eyes narrowed as he spread his wings wide. "You think numbers will overwhelm me?"

The Golden Arsenal
Kael raised his claws, summoning countless golden weapons—swords, spears, and axes—materializing in a dazzling display of light. Each weapon hovered around him, glowing with divine energy.
"Let's see how your shadows handle this!" Kael roared, launching the golden arsenal toward the duplicates.
The weapons streaked through the void like shooting stars, piercing through the chest of each shadowy duplicate. As each weapon struck, the duplicates disintegrated into dust, their screams echoing across the battlefield.
Kael spun mid-air, releasing another volley of golden weapons, erasing the remaining duplicates in a brilliant cascade of light.
When the chaos cleared, Kael and the original Demon King stood alone once more.

The Final Duel Begins
The Demon King stepped forward, his aura flaring with renewed power. "Impressive, Kael. But now it's time to end this."
Kael smirked, his golden eyes blazing. "Then stop stalling and show me what you've got."
Suddenly, the Demon King raised his claw, summoning an enormous, ancient, demonic eye. The eye hovered above the battlefield, pulsating with dark energy and gazing with malevolent sentience.
Kael's expression hardened. "That's no ordinary attack."
The eye turned and looked beyond the battlefield, peering into dimensions unseen. It caught sight of Miko, Kuro Shin, and Elder Ralnor, who were observing the battle from the past.
Elder Ralnor's face paled. "Ah, I forgot to mention... That eye can see across time and space. It's aware of us!"

The Darkness Unleashed
The demonic eye turned back to Kael and began to glow with an ominous red light. The Demon King spread his wings, his voice reverberating across the domain. "Ultimate Attack: Annihilation!"
The entire Universal Space Domain darkened as the attack activated. A massive sphere of darkness expanded outward, consuming stars, galaxies, and all forms of light.
Kael's golden aura flickered as the void turned into a sea of nothingness. The Demon King laughed triumphantly, his glowing red eyes piercing through the consuming darkness.
"I've devoured everything!" the Demon King declared, his voice filled with malevolent glee.

The Light Strikes Back
But then, a piercing light emerged from the abyss. It was Kael, his golden form shining brighter than ever, his voice echoing with divine power.
"You may have devoured everything, but light cannot be extinguished!" Kael roared.
Raising his claw, Kael unleashed his ultimate skill. "Let there be Light!"
A massive wave of golden light erupted from Kael, consuming the darkness in an explosive collision. The light spread across the void, restoring balance as it clashed with the Demon King's shadowy power.
The two forces collided repeatedly, creating shockwaves that twisted space and time. Stars reappeared, galaxies reformed, and the void pulsed with the struggle of light and darkness.

The Final Stand
Kael and the Demon King reverted to their humanoid forms, standing face-to-face amidst the swirling chaos of their energies. Their eyes burned with determination, their bodies radiating unimaginable power.
The Demon King began chanting in a guttural, ancient tongue, his words dripping with malice. Strange symbols materialized around him, multiplying the strength of his ultimate attack.
Kael responded by summoning the remnants of his golden energy, his aura flaring like a supernova.
"This ends now!" Kael declared, charging forward with a golden spear in hand.
The Demon King met him head-on, wielding a massive, dark blade. Their weapons clashed, sending shockwaves across the Universal Space Domain, as the final battle for existence began.
