Chapter 1: The Rifts Between Worlds
Ultra Space
A lone, fragmented island drifted through Ultra Space—until an explosion erupted from its surface, blasting a thick cloud of dust into the void.
As the dust slowly settled, a lone figure stood amid the wreckage.
He was Diamond, a trainer from Twinleaf Town in the Sinnoh Region. He looked about fifteen, with dark hair and a face streaked with dust and exhaustion. His breaths were shallow and ragged, weighed down by the battle and the strange world around him.
He wore a black V-neck T-shirt beneath a teal hooded jacket with short sleeves, trimmed with red and white along the hem. A Poké Ball logo adorned his right sleeve. His light brown pants, red-and-white sneakers, and light gray backpack with black outlines were all coated in dirt.
Diamond let out an exhausted sigh, standing beside his dirt-covered Pokémon.
Tru, the Torterra, stood exhausted but strong.
Lax, the Munchlax, lay on the ground, barely moving.
Fan Rotom flickered weakly.
Scattered across the battlefield, the broken remains of Rotom's appliances lay in pieces—its oven, washer, fridge, and lawn mower all battered.
Don, the Bastiodon, stood like a silent sentinel, his armor marked by battle.
Kit, the Lickilicky, was tired but standing.
And Moo, the Mamoswine, covered in debris, completed the group.
"How is it still standing?" Diamond thought to himself, mind racing. His Pokémon exchanged tired glances, but none of them complained. They were fighters—just like him.
From the far side of the island, a silhouette stepped forward.
Pheromosa.
Dusted and battered, the Ultra Beast stood tall, its elegant limbs coated in grime. The attack hadn't been enough. The air grew thick as it moved forward, graceful, yet undeniably weakened. Its gaze was sharp and unblinking.
Then, without warning, it lunged.
A blur of motion. A Poison Jab, fast as lightning, aimed straight for Diamond.
"Don!" Diamond called out.
"Bastiodon!"
Don rushed forward, throwing himself in front of Diamond. The attack struck him square in the face, but the sturdy Pokémon stood unfazed.
"Kit, Power Whip—now!"
Kit roared to life. With a grunt, he swung his long tongue in a lashing arc toward Pheromosa.
But it was too quick, darting up into the air.
Diamond's heart pounded.
"Not good... It's moving too fast. Can we even hit it in time?"
Above, Pheromosa hovered until it suddenly froze. Fan Rotom had drifted silently into position, just inches away.
Diamond's eyes flashed. "Now! Rotom, use Air Slash!"
"Roooo…tom!" With a spark of electricity, Rotom fired a slicing gust straight at Pheromosa, hitting it dead on. The Ultra Beast was knocked off course and crashed into the ground with a mighty thud.
But an Ice Beam shot through the dust cloud before Diamond could celebrate. It struck Fan Rotom directly. Sparks flew, and the ghostly Pokémon was blasted backward, spinning uncontrollably. The force of the hit separated Rotom's last appliance—its fan—which landed on the ground battered like the other appliances.
"Rotom!" Diamond cried out in alarm.
Before Diamond could move, Lax dashed forward and caught Rotom just in time, stumbling but keeping him safe.
Diamond knelt beside them. "You okay?"
Rotom buzzed faintly. "Ro...tom…"
"You did great. Just rest now," Diamond said gently.
He looked at Lax. "Watch over Rotom, okay?"
"Munchlax." The small Pokémon nodded and carefully sat beside Rotom, cradling the tired Pokémon.
With a quiet sigh, Diamond stood and turned his gaze back to the battlefield. The storm of dust had settled, but Pheromosa had returned.
"Phero..mosa." It moved slowly, steps uneven, body cracked and battered. But not giving in.
"It's still going…?" Diamond stared in disbelief
His team stood once more. Diamond slapped his cheek, feeling the determination surge through him. "Alright, one final stand," he said to his Pokémon.
"OK, Tru! Rock Slide!" Diamond commanded.
The earth rumbled. Boulders crashed down from above. Pheromosa weaved and dodged—until one block slammed down in its path, cutting off escape.
"Now we've got it! Moo—Ice Shard!"
Sharp shards of ice tore across the battlefield, striking Pheromosa square in the chest. It staggered, unable to avoid the hit.
"Pheromosa!" it roared, unleashing Bug Buzz.
"Ugh, this isn't good!" Diamond said while covering his ears. His Pokémon winced and staggered back, trying to resist the screeching sound.
But then, Pheromosa leapt forward, its glowing legs raised high as it aimed a High Jump Kick directly at Diamond.
Don rushed in, using Protect. The kick landed, but was deflected
Diamond gasped. "Don… thank you."
Pheromosa slowly recovered, its body twitching as it regained its senses. The Ultra Beast's eyes darted around, scanning its surroundings with razor-sharp precision.
It paused, a subtle shift in its posture as it realized something was wrong. One Pokémon was missing.
Without warning, the ground beneath it exploded—Kit burst from a Dig attack, slamming into Pheromosa and sending it sprawling.
"Kit! Nice one!" Diamond cheered.
Pheromosa struggled to rise, but Diamond could see the end was near. It was barely standing, its body bruised and battered.
Diamond's eyes gleamed as the end was near. "Tru, finish it! Wood Hammer!"
Tru charged forward, his tree-covered shell glowing as power surged into his legs. Pheromosa turned its head, just in time to see the final blow coming.
WHAM!
Tru's Wood Hammer slammed into Pheromosa with devastating force.
The Ultra Beast was hurled backward—
CRASH!
It smashed into a massive boulder, stone splintering on impact.
Dust exploded across the battlefield, swallowing the field in silence.
Then, slowly—
as the dust began to settle—
All eyes were locked on the broken shape slumped against the shattered boulder.
And there, unmoving… beaten…
Pheromosa lay defeated.
"It's over…" Diamond breathed, his voice weak but relieved. He sank to his knees as his Pokémon gathered around him, standing tall despite their injuries.
They had won.
For a moment, he simply sat there, the dust swirling around them in the stillness of Ultra Space. Everything felt distant—surreal, even.
He looked around at his team—tired, battered, but still with him.
Slowly, Diamond slung his backpack around and unzipped one of the side pockets. Beneath a spare Poké Ball case and a half-crushed Town Map lay a small bento box wrapped in a faded cloth patterned with red and white Oran Berries. He pulled it out gently, brushing off the dust.
His gaze softened. Then, with a familiar spark in his eyes, excitement bubbled up.
"Alright, enough with the emotional rollercoaster," he declared. "It's lunchtime!"
"Let's eat. We earned this meal."
He untied the cloth and pulled it back, revealing a neat row of onigiri tucked inside.
The note tucked under the lid caught his attention, and he smiled as he read it.
"I pack this onigiri, knowing you would get hungry. – Love, your mother."
Diamond gave a quiet, crooked smile. "Thanks, Mom."
Diamond took a bite of the rice ball, savoring its comforting taste. His Pokémon gathered around, enjoying their well-deserved meal in the strange void of Ultra Space.
Kit lazily curled his tongue around an onigiri while Lax snored softly, hugging Rotom like a pillow. Moo nudged a rice ball closer with his tusks, and Don ate slowly, dignified as always. Tru, ever relaxed, calmly munched on his portion, content in the moment.
"Man, this is the weirdest place I've ever had lunch," Diamond muttered, wiping his mouth. "I came to Alola for a vacation, not to get sucked into Ultra Space and battle Ultra Beasts."
His Pokémon all shared a quiet moment of contentment in the strange stillness of the void.
Diamond adjusted his backpack, the familiar weight settling on his shoulders. With a stretch, he smiled. "Well, no use crying over spilled onigiri," he said, standing tall. "Let's find somewhere to rest first. After that, we'll figure out how to get out of here."
His team roused themselves, ready to continue. Tru led the way, followed by Kit, Moo, Lax, and Rotom, who were still weak but determined.
Then, just as they took their first steps forward, a loud sound ripped through the silence.
A beam of bright light shot from far away, fast and direct, heading straight for Diamond.
His eyes widened. "What—?!"
He barely had time to react before the blast struck.
In an instant, Tru, Kit, Moo, and Don leapt in front of him, acting on instinct, shielding their trainer with their bodies.
"Everyone—!" Diamond cried out in disbelief.
The beam struck.
It tore through the air with a deafening roar, detonating on impact like a rocket engine igniting at full force. The shockwave blasted outward, launching Diamond and his Pokémon into the void. He felt himself hurled backward, weightless—like a rocket blasting off into the endless stretch of Ultra Space. Even the scattered pieces of Rotom's appliances were flung into the air, careening like random debris in a chaotic, explosive blast.
The space around them twisted.
Then the air behind them shimmered—and split.
A massive Ultra Wormhole opened wide, its glowing threads stretching outward like unraveling light. The pull was overwhelming. There was no escaping it.
Diamond reached out desperately for his Pokémon—arms stretched, heart racing. His grip found Lax, who had clutched Rotom tightly in his grasp, trying to shield the weakened ghost from the blinding light.
"Hold on, Lax!" Diamond cried, desperately pulling the Munchlax into his arms. But the light was too powerful. He felt himself being ripped away from everything he knew, the suffocating pressure unrelenting as it dragged him into the unknown.
There was no time to scream—no air to carry the sound. Diamond could only hold Lax tighter as the force of the wormhole pulled at them.
Lax. Rotom. Tru. Don. Moo. Kit. Even the shattered pieces of Rotom's appliances.
All of them were swallowed by the light.
And then—darkness.
Outside U.A. Campus
The sun dipped beneath the horizon, spilling golden light across the U.A. campus. Evening shadows stretched long across the stone paths, and a gentle breeze rustled the trees that lined the back garden. The school grounds, usually bustling with the energy of aspiring heroes, lay still. Almost too still.
Principal Nezu and Hound Dog emerged from the main building, their footsteps faint against the silence. The calm before the storm of the new academic year felt almost like a rare pause, a breath before everything began again.
Nezu's eyes gleamed with excitement as he looked over to Hound Dog. "Ah, and there's another important change this year—the addition of rescue points to the entrance exam."
Hound Dog raised an eyebrow, his attention now fully on Nezu. "Rescue points? You mean they'll be scored for saving civilians, not just defeating villains or completing obstacles?"
"Exactly," Nezu replied, his tail flicking behind him. "We've incorporated a new dynamic into the exam. While the physical challenges will still be present, we want to emphasize the true essence of being a hero—saving lives. Participants will now be awarded rescue points based on their ability to assist and protect civilians during the exam."
Hound Dog's expression became thoughtful, considering the implications. "So, it's not just about how strong or fast they are. It's about their judgment and ability to prioritize what's important in a chaotic situation."
Nezu nodded enthusiastically. "Precisely! A hero is not just someone who can fight. They must also be able to think quickly, assess the situation, and make decisions that protect the innocent. The exam will feature scenarios where the participants must decide between engaging with a villain or rescuing civilians caught in the crossfire. The challenge is to balance both, which is a critical skill for any hero."
"That's a smart move," Hound Dog agreed, his voice gruff but approving. "A real hero knows when to fight and step in and protect people who need help. I think it'll test the candidates in ways they haven't been tested before."
As they continued their quiet walk, the conversation about the entrance exam still fresh in their minds, a sudden, bright flash erupted from the south tree line. It wasn't lightning, nor a malfunctioning light—this was intense, pure, and blinding, lasting only for the briefest of seconds. The glow bathed the nearby treetops in a stark white hue before vanishing completely, leaving only darkness in its wake.
Nezu's sharp gaze snapped toward the source of the flash, his curiosity hardening into precision.
"Well, well… what do we have here?" he murmured, ears standing tall, his tail frozen mid-sway.
Hound Dog's instincts kicked in instantly. His body tensed, posture low, eyes narrowing toward the direction of the light.
"That wasn't normal," he growled. "Something's off about it. Way too fast and clean to be lightning."
Nezu's eyes remained locked on the tree line. The flash had vanished without a trace—no glow, residual light, but the memory of its brilliance. Like a camera flash in the middle of nowhere.
"Unnatural. Sudden. Controlled," he said softly, voice quiet but deliberate. "That wasn't random."
He reached for his comms device and raised a paw, his voice calm but edged with decisive urgency. "Ectoplasm, we've detected a sudden bright flash from the south tree line. It lasted a moment and vanished—potential Quirk activity or unauthorized presence. Proceed with caution. No alarms unless necessary."
A faint crackle answered, followed by Ectoplasm's voice through the static. "Copy that. I'm en route. I'll approach from the east perimeter and sweep the area. Stand by."
Nezu lowered the comm and turned to Hound Dog, who was already adjusting his stance, muscles coiled and ready.
"Let's move in quietly," Hound Dog said, his voice low and steady. "I doubt any student would be out here right now—so that leaves one possibility: an intruder."
Nezu gave a small nod. "Then we make sure it doesn't take another step onto this campus."
The two of them moved forward—silent, cautious, and aware that whatever had caused that flash might still be watching from the dark.
South Tree Line
Nezu and Hound Dog approached with care, their footsteps muffled against the soft forest floor. Overhead, the last streaks of daylight faded, allowing the early stars to peek through the canopy. But here, beneath the trees, darkness pooled heavily between the shadows.
Suddenly, Hound Dog stopped, his posture tense, ears twitching with focus. He began sniffing deeply.
"I count seven scents," he growled, his voice a quiet rumble. "One's human. Young. Male."
He shifted slightly, his nostrils flaring as he sifted through the lingering traces in the air, his eyes narrowing.
"The others... they're not human," Hound Dog said, his voice tense. "I don't recognize them. Not animals. Something... completely different. Their scent is faint."
A shift in the shadows ahead signaled another presence that moved without sound.
From the darkness, Ectoplasm emerged, his spectral form slipping through the trees like mist. He gave a short nod in greeting, his tone low and composed.
"I felt it too. The air's charged—like something passed through this place that doesn't belong."
Hound Dog straightened slightly, motioning toward the direction of the strongest scent. "They're close. Just ahead."
Nezu's eyes gleamed faintly in the low light as he exchanged a glance with both of them.
"Then let's not waste time."
They moved in silence, the forest growing denser around them as the moonlight barely filtered through the thick canopy. The scent trail was strong now, leading them toward a thinning in the trees where the air felt heavier, charged with something unseen.
As they stepped past a curtain of low-hanging branches, the forest suddenly opened into a small clearing.
And there he was.
At the center of the clearing lay a boy, no older than fifteen. His skin was pale, his limbs sprawled across the grass like a discarded doll. He didn't stir. The only indication that he was alive at all was the faint, unsteady rise and fall of his chest—shallow breaths, like his body was barely clinging to consciousness.
Hound Dog halted beside Ectoplasm, a growl rising quietly in his throat. "That's the human scent. Right there."
Nezu's voice followed, calm but edged with something deeper—curiosity, concern… and calculation.
"…But he's not alone."
Around the boy, six figures lay strewn across the clearing—draped over rocks, slumped against roots, or curled in the grass. None of them were human. Not familiar.
A small, round-bodied creature sprawled across the boy's chest, like a forgotten toy. Its stubby limbs hung limp, its soft fur matted with grime and dust. Each breath it took was faint and shallow—less like sleep, more like surrender.
From its tiny arms, a dim flicker of orange and blue plasma pulsed—brief, flickering, fragile. Like the last glow of a dying ember, the spark danced
At the boy's feet was a massive turtle-like creature, its moss-covered shell cracked in places, dirt clinging to its edges. It didn't stir, breathing barely visible. It looked like it had been carved from the earth—weathered, ancient, unmoving.
Leaning against the boy's side was a squat, heavily-armored beast, its shielded face battered, scorched in several places. It looked like it had been through a war.
Nearby, a hulking, furred creature with curled tusks lay stretched out in the dirt. Steam drifted slowly from its nostrils, each breath slow and strained.
And finally, just beyond them, a pinkish figure was splayed awkwardly on the ground, its thick tongue trailing through the grass. It too barely breathed.
Hound Dog's voice dropped low, heavy with concern. "They're drained. Every single one of them. Like they've been through hell."
Ectoplasm crept closer, shifting silently between shadow and mist. As his eyes adjusted to the strange scene before him, he stiffened.
"They're surrounded," he said, eyes scanning the edges of the clearing. "But not by enemies…"
He paused.
"…by appliances."
Hound Dog blinked. "Appliances?"
Scattered throughout the clearing were ordinary household devices, though battered, scorched, and strangely placed. A cracked microwave. A bent floor fan. A rusted lawnmower. A dented washing machine. A toppled refrigerator with its door ajar. All of them were the same odd, burnt-orange color. All of them are silent. Lifeless.
It looked like a battlefield. But the weapons were absurd. And still… something about it felt intentional.
Hound Dog sniffed again, unsettled. "What the hell happened here?"
Nezu didn't answer at first. He simply stared, expression unreadable, ears twitching with calculation. His eyes lingered on the boy, the creatures, and the machines. Finally, he raised a paw and pressed a finger to his comm.
"Call Recovery Girl," he said evenly. "And alert the medical team. No alarms. No media. Not yet. We're dealing with something… unprecedented."
Ectoplasm looked at him. "Containment?"
Nezu shook his head. "Have them on standby. No restraints. No aggression." His voice sharpened, final. "They're not prisoners. They're guests."
And as the wind rustled softly through the trees, the strange machines remained silent, watching like relics of a story no one had told.
The boy didn't stir.
But in the air… something stirred for him.
