PokeIsland - Exploring the New Base

The sun shone brightly on PokeIsland as Xpovac and his crew stood before the newly constructed base, towering over the island like a fortress. The sheer size and grandeur of it impressed even Xpovac, who had grown accustomed to monumental feats. His Pokémon stood alongside him, staring up in awe as they prepared to explore their new home.

"Let's check this out," Xpovac said, gesturing for his Pokémon to follow him inside.

As they walked through the wide stone corridors, Xpovac noted the various rooms laid out perfectly by the system's design. The first room they entered was a Pokémon Daycare, where younger or less experienced Pokémon could be raised and nurtured. Several incubators lined one of the walls, glowing softly in anticipation of the Pokémon eggs Xpovac planned to place there.

Next, they entered the Pokémon Park, a wide, open expanse filled with lush greenery, lakes, and playground-like structures designed for Pokémon to train, play, and relax. Xpovac smiled, imagining his Pokémon enjoying themselves here during downtime.

From there, they moved into the Treasure Room a cavernous space filled with various treasures and valuables Xpovac had acquired in his adventures. This room was where he would later place many treasures.

Further into the base was the Training Room, outfitted with the best equipment to hone both physical and spiritual strength. It had specialized zones for practicing with different weapons, from swords to haki, as well as areas for Pokémon to practice their attacks in a controlled environment. Xpovac noted how his own training would benefit greatly here.

After exploring the base, Xpovac clapped his hands together. "This place is perfect," he declared, his Pokémon nodding in agreement.

Turning to the system, Xpovac issued his next command, "System, purchase 100 Pokémon eggs. Put them in the incubators and transfer them to the daycare when they're ready."

Within moments, the incubators filled with eggs from every generation of Pokémon. The glowing warmth from the machines hummed softly as the process began. It would take about 30 minutes to an hour for them to hatch.

During that time, Xpovac assigned his main Pokémon the task of overseeing the island's protection until more legendaries could be acquired. "You guys need to keep the island safe. We'll have new additions soon," Xpovac said with a grin.

When the eggs finally hatched, the base filled with the sounds of newly born Pokémon. Charmanders, Pidgeys, Rattatas, Eevees, and countless others from across the generations emerged from their shells, all looking up at Xpovac with awe. These common Pokémon were the beginning of something grand on PokeIsland.

The Gacha Spins

With the island secured, Xpovac decided it was time to use his recently earned gacha spins. He called up the system and selected the two S-Tier+ spins.

> Spin 1: Millennium Puzzle.

> Spin 2: Zanpakuto.

Xpo smirked as the Millennium Puzzle materialized in his hand, its ancient golden pieces glimmering with mystery and power. He immediately decided that it belonged in the Treasure Room, alongside his other treasures. As for the Zanpakuto, he felt the energy of the sword flow into his hand. This was not just any blade; this one had a spirit, a partner, waiting for him to uncover its name.

"Looks like I have a new friend to bond with," Xpovac said to himself, feeling the latent power of the Zanpakuto resonate with his own. Over the next five days, Xpovac trained rigorously with the sword, meditating and focusing to unlock the name of his new partner. He could feel he was on the cusp of learning the name, but it eluded him just slightly.

Legendary Eggs Hatch

After five days, Xpovac felt a tingle from the system. It was time. Opening the store once again, he purchased three Legendary Pokémon eggs, hoping for some of the stronger legends to watch over the island.

> System: Legendary Eggs Purchased.

> Time until hatch: 24 hours.

A day later, Xpovac and his Pokémon stood eagerly around the incubators. The eggs glowed brightly before shattering into light, revealing three mighty figures:

1. Necrozma: A towering, jet-black figure with diamond-shaped wings that glowed with a cosmic aura. Necrozma's presence was overwhelming, its very essence radiating control over light and darkness. Its gaze was calculating, as if it could bend reality to its will.

2. Moltres: The legendary firebird spread its fiery wings, flames flickering along its body as it soared into the air. Moltres screeched a majestic call, flames bursting around it in a display of raw power. The air around it shimmered with intense heat.

3. Mewtwo: Clad in sleek purple and gray, Mewtwo emerged, its psychic aura flaring around it as it floated effortlessly in the air. Its gaze was piercing, a mixture of intelligence and battle-ready determination. The sheer force of its presence made the air vibrate.

Xpovac grinned at the sight of these new legendary allies. "Welcome to the team," he said, his eyes gleaming with excitement.

Turning to the system, Xpovac had one more request. "System, buy me a Hyperbolic Time Chamber with a gravity function. Make it have its own room in the base."

The purchase was made, and a door appeared in one of the deeper chambers of the base. Beyond it was the Time Chamber, where gravity could be controlled, and time itself stretched beyond the limits of normal space.

Training the Legendaries

With his new Pokémon hatched, Xpovac decided to put them to work. He sent Necrozma, Mewtwo, and Moltres into the Time Chamber with Lugia, instructing them to train for a full year inside, though only a day would pass on the outside.

For a day, Xpovac waited, continuing his own training. He spent the next 24 hours inside the chamber himself, pushing his body to the limit under 50x gravity, feeling the intense strain but also the immense growth.

When Lugia and the legendaries returned, they were visibly stronger, their auras even more intense than before. Xpovac assigned them the roles of protecting the island, and ensuring its safety.

The Breaking Point

After a day of non-stop training, Xpovac exited the chamber, his body and spirit strengthened. But just as he stepped outside, the system issued a new notification.

> System Alert: Ace has been defeated by Blackbeard and sent to Impel Down. Luffy's crew has been separated.

The words hit Xpovac like a punch to the gut. Blackbeard had followed through with his treachery, and now Ace was imprisoned. Rage flooded Xpovac's mind, his vision blurring as his power began to spike uncontrollably. The ground beneath him trembled, and in an instant, a massive *red-eyed black dragon* appeared, summoned by Xpovac's fury.

The dragon let out a mighty roar, and its aura surged outward, shaking the very seas. The sky darkened, and the earth itself seemed to tremble in fear. Xpovac's power exploded outward alongside the dragon, causing the world to shudder as if nature itself feared his wrath. Massive waves rocked the oceans, and lightning split the sky as he leaked out his immense power.

His Pokémon, sensing their master's rage, growled and roared in response, their own power escalating, adding to the destruction. The world seemed to quake under the combined force of Xpovac and his creatures.

After five minutes of chaos, Mew intervened, floating before Xpovac with a calm yet determined look. Slowly, it calmed him, urging him to rein in his power and de-summon the dragon. Xpovac, breathing heavily, managed to regain control, his aura subsiding as the dragon faded away.

Switching POVs

Across the world, the aftermath of Xpovac's uncontrolled fury became evident.

On multiple islands, people were left shaken, staring in disbelief at the destruction caused by forces they couldn't comprehend. Buildings had collapsed, waves had flooded coastal towns, and the skies still rumbled ominously, as if the world itself had suffered a great wound.

Shanks, far out at sea, felt the power and recognized it instantly. His face grew serious. "That's Xpovac's power… but why?" He thought of Ace and knew the reason. Worry crept into his mind. "If Xpovac is this angry… things could get much worse."

At Impel Down, Garp stood at the entrance, his hands clenched into fists. He had felt his grandson's power shake the world, and he shared his rage. "Blackbeard," he growled. "You've unleashed a force you can't handle. And for what? Power? You fool." Garp looked up at the massive prison, preparing himself to speak with Ace.

Meanwhile, Luffy, still reeling from the loss of his crew, stood on Amazon Lily, gazing at the chaos caused by Xpovac's power. His mind raced, confused by the destruction. "Why's Xpovac so angry?" he muttered to himself.

Back to Xpovac

After calming down, Xpovac sighed deeply, shaking off the last

 remnants of his rage. He turned to his Pokémon, who had gathered around him.

"Get ready," Xpovac said, his voice steady now. "When Ace's execution day comes, we're taking action. Until then, we train."
