In Another World With Omnitrix

The silence in the icy chamber was suffocating.

Frost coiled around ancient metal and stone like ivy, growing thicker the deeper Riven went. His boots crunched over thin sheets of ice layered atop worn tiles marked by symbols he couldn't decipher. The chill wasn't just physical — it was ancestral. Like the walls remembered a time before warmth.

This place wasn't built. It was sealed.

And something inside was still alive.

He stepped into the core of the dungeon — a domed vault lined with pillars of jagged crystal. Old scaffolding and shattered machinery jutted from the sides like broken bones. At the center stood a massive altar of sorts, partially encased in ice.

Lining the walls were motionless figures. Dozens of them.

They weren't statues.

"Test subjects?" Riven whispered.

Some wore long-rotted uniforms. Others had armor, blades still frozen in their sheaths. All were preserved in haunting stillness. Faces caught in terror, some mid-scream.

The Omnitrix on his wrist pulsed — once. Then again, brighter.

"Compatible alien DNA detected. Source within 5 meters."

Riven's breath caught.

At the heart of the room was a hulking mound of ice and armor. At first glance, it looked like a broken mech, half-buried. But then the glow pulsed — a cold blue light in the center of its chest.

It look like it was breathing.

A voice echoed through the chamber, mechanical and ancient:

"Cryo-golem system: rebooting… core stabilizing… intruder detected."

The ice cracked. Limbs unfurled. A giant stood.

It was at least twelve feet tall, its body made of jagged armor and rune-carved frost plating. One arm ended in a massive hammer-fist, the other a cleaver of crystalline ice. Its chest pulsed with swirling alien energy — a broken core trying to stabilize.

The frozen walls trembled. And the door behind Riven slammed shut.

"Guess it saw me," he muttered.

He slammed down the Omnitrix dial.

Green light flared.

Flames roared.

"HEATBLAST!"

Heatblast emerged with a fireball already in his hand.

"Round one, popsicle."

He launched it straight at the golem's face. The impact cracked a chunk of frost off its shoulder, but the creature didn't even flinch. It raised its arm and launched a wall of spikes from the ground — Riven dove aside, the ice grazing his leg.

He returned fire with a sweeping arc of flame, catching the Golem's leg and searing the ice-plated joint. The behemoth stumbled slightly.

"Temperature anomaly detected. Initiating adaptive resistance."

The golem's runes flared brighter. The armor around its legs thickened with rapidly regenerating frost.

"It's learning already?" Riven growled. "You've got to be kidding me."

He blasted again, aiming higher. The golem raised its hammer-arm, blocking the flames. Its shield cracked — but the heat was clearly losing its edge.

Then the Golem struck.

Its hammer slammed down. Riven threw up a shield of flame and rolled back — but the shockwave of the impact sent him flying.

He crashed against a column, sparks trailing from his arms.

Omnitrix energy: 64%

Still holding, but the cold wasn't helping. This wasn't a normal environment. The dungeon was draining him in more ways than one.

"This place is built to kill fire," he muttered, staggering up. "Figures."

The golem advanced slowly, each step shaking the ground. Its chest glowed more erratically now, pulsing in time with the Omnitrix's feedback.

Riven noticed it — every time the golem used energy to attack or regenerate, the core shimmered. Became unstable. That was his opening.

"Alright." he muttered. "Let's get clever."

He transformed back, conserving energy. Flames fizzled out, and cold slammed into him like a wall.

He ducked behind an overturned scaffold, scanning the chamber. The ceiling was filled with hanging icicles — heavy. Deadly. There were frozen pipes snaking along the walls. Steam valves. Rigid terrain that could be manipulated.

And at the center, one very angry golem.

He took a breath, then dashed out from cover.

"HEY, ICE HEAD!" he shouted.

The golem turned and fired a barrage of ice lances. Riven zig-zagged between them, letting one slice past his shoulder — tearing his sleeve but missing vital flesh.

"Arghh"

He dove behind a broken console and flanked left.

Then, just as the golem lifted its arm for a follow-up slam—

Riven pulled a loose pipe and yanked it hard.

A column of pressurized steam erupted — blinding the golem for just a second.

That was enough.

He slammed the Omnitrix again. Green light burned.

Heatblast was back.

He launched upward using a fire jet and aimed a focused stream directly at the golem's chest — not to damage it, but to keep the core destabilized.

The Golem groaned. The runes on its body flickered wildly. Its stance shifted — slow, confused.

Omnitrix: 43%

He jumped back as the golem retaliated with a wide arc of its cleaver arm. The shockwave shattered a pillar. Debris rained down.

One of the large icicles fell — stabbing into the golem's shoulder. It roared, falling to one knee.

Its core pulsed, brighter than ever.

Then the Omnitrix beeped — different this time.

Not a warning.

A signal.

"Unknown alien DNA synchronized. Species: Polar Manzardill. Transformation available."

Riven froze.

"Right now…?"

The golem tried to rise, its body still sparking and groaning from the strain.

Riven looked at the Omnitrix. The symbol was spinning slowly. A new silhouette had appeared.

Thin. Reptilian. Sharp-finned.

His breath fogged. His hands trembled — not from fear. From the cold. From the thrill.

"That thing… that thing was powered by alien DNA. This whole dungeon was built around it."

He looked at the barely-standing Golem, and his eyes narrowed.

"And now it's mine."

He raised his arm, Omnitrix dial glowing green.

But he didn't press it. Not yet.

The moment wasn't over.

And he wasn't finished.

End of chapter.

Thank you for reading.
