The Thunderous Battle! Kuuga vs. Shadow Moon!

At that moment, Kamen Rider Shadow Moon raised his hand, releasing countless green lightning bolts. The bolts, like wild dragons unleashed, wreaked havoc around them. The area around Kamen Rider Kuuga exploded, forcing him to leap to avoid the blast.

However, while airborne, Shadow Moon fired another wave of green lightning. The bolts coiled around Kuuga like serpents, slamming him into a wall. The impact damaged the wall, and Kuuga nearly collapsed from the force.

Shadow Moon approached with his sword. Kuuga rolled away just in time, narrowly avoiding the attack. Rising swiftly, he countered with his Dragon Rod. The two clashed fiercely, but it was clear that Shadow Moon had the upper hand. Each strike from Shadow Moon was deadly, forcing Kuuga to stay on the defensive.

Shadow Moon's relentless attacks eventually broke Kuuga's Dragon Rod. As Shadow Moon's sword descended for a final blow, Kuuga barely managed to block it with his broken weapon. The impact sent sparks flying, and Kuuga was thrown to the ground, gasping for breath.

As Shadow Moon advanced, Kuuga's body began to change. His blue colour faded, replaced by a silver armour with purple edges. His eyes turned purple, and his broken weapon became a purple-edged golden sword.

When Shadow Moon swung his sword again, Kuuga met the strike head-on. Their blades clashed, creating a blinding flash of light. Surprised by Kuuga's resilience, Shadow Moon attacked again, only to be blocked each time.

The two exchanged rapid blows, their movements becoming blurry. Neither could gain the upper hand, and the battle reached a stalemate.

Elsewhere, S.H.I.E.L.D. agents struggled against Pierce's Gaia Memory-enhanced soldiers, who vastly outnumbered them. Even Director Fury had to take up arms to protect the Cosmic Cube. But conventional weapons were ineffective against the Dopants.

Seeing the dire situation, Kamen Rider Kabuto activated his Clock Up system, entering a state of super speed. He moved too fast for the Dopants to see, striking them down with powerful blows.

"Clock Up!"

In the blink of an eye, Kabuto knocked out several Dopants, their bodies flying through the air before exploding. He landed, striking a pose as the explosions illuminated his back.

"Not even worth my time," Kabuto muttered, pointing to the sky.

Furious, Pierce transformed into the Weather Dopant and launched himself at Kabuto with a lightning whip. The whip moved unpredictably, making it difficult for Kabuto to dodge. When he tried to counterattack, Pierce kicked him away with incredible force.

Kabuto quickly recovered, but Pierce summoned a storm cloud, unleashing a barrage of lightning. Kabuto punched the bolts away, but the constant assault began to wear him down. Realising the danger, Kabuto prepared to accelerate again.

"Clock Up!"

But Pierce anticipated this, ensnaring Kabuto with his lightning whip. Electricity surged through Kabuto, causing him to cry in pain and collapse. Pierce continued his relentless attack, laughing maniacally as lightning and explosions consumed Kabuto.

Despite the overwhelming odds, Kabuto refused to give up. As the dust settled, he activated his Hyper Clock Up system, transforming into Hyper Kabuto. His armour glowed renewed power, and he drew his Hyper Zecter sword.

Hyper Kabuto closed the distance with blinding speed, slashing through Pierce's defences. The Weather Dopant's attacks were no match for Hyper Kabuto's speed and strength.

"Hyper Clock Up!"

Kabuto moved faster than the eye could see, delivering a flurry of strikes. Each blow resonated with thunderous impact, finally bringing Pierce to his knees.

"You... can't defeat me!" Pierce screamed, summoning all his power for one final attack.

But Hyper Kabuto was already prepared. He raised his sword, channelling his energy into a devastating finishing move.

"Rider Kick!"

With a powerful leap, Kabuto delivered a crushing kick to Pierce, shattering his Gaia Memory and sending him flying. The explosion that followed marked the end of the Weather Dopant.

As the dust settled, Kabuto stood tall, victorious. The remaining Dopants, witnessing their leader's defeat, hesitated, giving S.H.I.E.L.D. the opening they needed to turn the tide.

Amid the chaos, Kuuga and Shadow Moon continued their fierce duel. Kuuga, now in his ultimate form, faced Shadow Moon with renewed determination. The battle of Showa and Heisei was far from over, but the tide had begun to turn in favour of justice.
