Well, hello there, you folks and welcome to this story itself.

Now, before I want to start, I just want to ask something.

I have finally been given the permission to take inspiration from 'The Empire's Doomsday' by 'Andrew78591' which, spoilers, is what will happen when the author had watched the Death Battle of Hulk vs Doomsday, I would like to ask: what kind of monster or villain should I put in Akame ga Kill?

I do wanted to try Scion from the Worm series but unfortunately, I don't know much about Worms at all and what can I actually do to actually implement Scion in Akame ga Kill.

I could try V1 from Ultrakill or Homelander from The Boys or anything that is so destructive and evil that it will actually make enemies become allies when dealing with a much more dangerous threat.

And besides, at least it's better than whoever takes inspiration from the story itself with their serious seizure inducing grammars, poor writing and many many more problems from reading that crap.

Hell, I could even try to make an Akame ga Kill/Doom Crossover where demons are invading the Empire or a RWBY/Akame ga Kill crossover where the Grimm are invading the Empire.

Or even the Skaven from Warhammer Fantasy.

Or the Genestealer Cult from Warhammer 40k, maybe even the Dark Eldar, if only because I could have helped with that.

Hell, if you have anything, let me know in the comments below.

Now, enjoy the story.

In the world of planet Earth, there lived it's inhabitants...

The Terenos...

A race of bipedal species of ultimate perfection, formation, strength and power where they are a dominant force on their home planet, having been blessed with a resilient and very adaptive body that allows them to survive through anything that no matter the dangers of the environment from jungles to deserts to cold winters to volcanoes, the Terenos are able to adapt their bodies to survive and withstand such a dangerous environment with ease.

And with such adaptation comes their ability to make homes in anything as aside from the race's blessed powers of adaptability but also immense intelligence and they have been creating many levels of advance technological machines, tools and more, having created buildings that are shown to be incredibly monumental in the scope and scale, it's design being sleek and clean, a testament to them being an intellectual, enlightened and civilised display of their orderly culture.

Overall, they are a race that are truly considered to be the perfect civilization and one would think that they are either chosen or by prestige in what they had achieved in how they become such an advanced and perfect race that ruled the planet of Earth like how they truly owned the place.

But now...

Now is the time where they will put their intelligence and adaptability to the test.

The sun, a molten pearl in the cerulean sky, cast a warm glow on the gleaming spires of Xylos, the Terenos capital. It was a day of vibrant beauty, a deceptive calm before the storm.

Below, in the meticulously ordered streets, the Terenos bustled with a strange mix of urgency and quiet resignation.

The Age of Calamity was upon them.

Eryx, with his metallic sheen of skin, vivid teal eyes, and silvery waterfall of hair, was an unremarkable cog in this well-oiled machine. His minimalist high-collar jacket, shifting subtly from a calm blue to a thoughtful grey as he walked, reflected the subdued mood of the city.

He was a Terenos citizen, perfectly adapted to their technologically advanced world, yet utterly average. He was, he thought, perfectly content with that.

His comm-unit chirped, his friend, Lyra's voice slicing through his thoughts. "Eryx! Where are you? We're almost ready!"

"Just taking a morning stroll," Eryx replied, his voice calm. "I'll be home soon."

Lyra's tone shifted. "Just…make sure you're on time. Okay?"

The unspoken hung between them, heavy with the knowledge of the impending supernova.

The scientists had delivered their grim verdict: the sun was nearing critical overload.

Even the Terenos' unparalleled adaptability couldn't save them from that.

Their salvation lay in the Cryo-Chambers – state-of-the-art hibernation pods designed to see them through the apocalypse, waking them only when the danger passed.

Eryx sighed, his jacket flashing briefly with a tinge of irritation. He watched a scene unfold on a nearby plaza: a squad of Terenos, clad in armoured riot gear, herded a group of humans into metal cages.

The humans, primitive and brutish in their defiance, struggled, their cries swallowed by the city's hum.

Eryx felt a flicker of something akin to pity, quickly suppressed.

Humans.

A troublesome, primitive species that are only served as a necessary workforce for the truly ultimate race like the Terenos, nothing more.

Their inherent violence and unpredictability made containment necessary as he watched them being caged with such a detached air.

Lyra's voice crackled in his comm-unit. "What is it?"

"Nothing," Eryx said, his tone flat. "Just… the usual human wrangling."

"Damn Terenos elite getting all the slaves," Lyra grumbled. "Us working stiffs don't get the luxury of human servants."

Eryx rolled his eyes. "What difference does it make? It's all ending soon anyway."

He paused. "Frankly, I'm glad I don't have to deal with those…things." He chuckled, a dry, humourless sound. "Probably busy making a mess somewhere."

Lyra laughed, a harsh sound that mirrored Eryx's own amusement. "True enough. See you at home, then. Good luck."

The call ended as Eryx continued walking, his steps brisk. He reached his apartment, a sleek, minimalist space reflecting his personality.

The Cryo-Chamber stood ready, a silver monolith humming softly in the corner. The city-wide announcement blared, its synthesized voice devoid of emotion: "Age of Calamity commencing. Initiate Cryo-stasis protocols."

Eryx activated the chamber, the smooth surface yielding to his touch. He stepped inside, the cool embrace of the pod enveloping him. He lay down, the soft padding cushioning him.

As the chamber sealed, a wave of drowsiness washed over him. He closed his eyes, visions of his friends, family, and a future, however uncertain, filling his mind.

He would dreamt of a time when the sun would shine again.

He would dreamt of a dawn after the apocalypse.

He would dreamt of a world where he and his people would emerge triumphant, adapting and thriving once more.

And maybe, just maybe, the humans would finally learn to clean up after themselves.

The ache in his bones was a familiar kind of torment, the kind that followed a long, unwanted sleep.

Eryx's eyelids fluttered, finally giving way to the faint, cool light filtering through the glass of his Cryo-Chamber.

He felt a strange combination of relief and trepidation bubbling in his chest.

Relief that he was awake, trepidation at the unknown that awaited him.

He remembered the panic, the chaos, the inevitability of the Age of Calamity.

The Terenos, with all their adaptive prowess, had no defense against the cataclysm.

Cryosleep had been their only hope.

The chamber hissed and slid open, and Eryx, stiff as a board, pushed himself to a standing position.

He stretched, feeling his muscles protesting at the sudden movement, and let out a long, groggy yawn.

He imagined Lyla's bright smile, her infectious laugh, and the anticipation of seeing her again quickened his heart.

They'd been so close, making plans for after the awakening. The thought propelled him forward, but just as he took his first step, the world lurched.

He was dangling, his fingers scrabbling for purchase on the cold, metal edge of the Cryo-Chamber. It hung precariously, a metallic island jutting out from the precipice of a vast drop.

His heart pounded in his chest, the initial excitement replaced by a primal fear that constricted his throat. He took slow, deliberate breaths, forcing himself to calm down.

He looked up at the chamber, its wires frayed and barely holding on.

It was a cruel joke, a twisted reminder that the world he knew was gone.

Then, the inevitable happened for with a sickening snap, the wires gave way, and Eryx screamed, the sound lost in the vastness of whatever void lay below.

He hit the ground with a bone-jarring thud, the air whooshing from his lungs as dust and debris swirled around him, and for a moment, he could only cough and groan, the impact sending waves of pain through his body.

He was a Terenos, built to endure, but even for him, that fall had been brutal.

Slowly, Eryx pushed himself up, his body protesting with every movement. He looked around, and his breath caught in his throat.

The scene before him was a stark and horrifying contrast to the gleaming city he remembered.

Gone were the sleek, monumental structures of Terenos ingenuity and now, it is instead a wasteland of twisted metal, crumbling concrete and vegetation that had aggressively reclaimed what was once their domain.

The open, airy designs of his people's architecture were now obscured by decay.

This wasn't just neglect; it was annihilation.

Where were the government's preservation plans? Where were the automatic repair systems? This was not how he'd imagined their return. A cold dread began to creep into his heart. He had expected the buildings to be somewhat weathered, maybe even a little overgrown, but not this… this utter devastation.

Then, the horrifying realization hit him:The people!

"Lyla!" he cried out, his voice echoing in the ruins. "Can anyone hear me? Is anyone there?" He yelled until his throat was raw, desperately hoping for a response, for any sign that he wasn't alone. His cries were met with silence. He screamed again, each shout filled with a growing panic, yet still, silence answered.

He couldn't wait any longer.

His Terenos heritage granted him incredible speed, and he channeled his fear and adrenaline into his legs, bolting across the ruined landscape, becoming a blur of motion as leap over fallen debris, wall-running on battered structures and sliding across collapsed walkways.

He pushed himself through in his determination, tenacity and a single-minded drive through the desperation of a young man trying to find his people that have been mysteriously disappeared where their should have been survivors in this ruin.

He even used his Terenos abilities to smash through walls, kicked open doors, and flipped through ruined vehicles, all in his hope to find them yet as he continues to search through empty rooms, empty streets and empty buildings with no living soul in sight, his hope dwindled.

Worse is that Cryo-Chambers, where his people were supposed to be, were also wrecked, their metallic shells twisted and broken.

Panic threatened to engulf him but he has an idea as thankful that he sleeps in the Cryo-Chamber with his comm-unit, he then activated it with his shaky fingers, his hopes momentarily rising.

He tried to send a distress signal, tried to connect with anyone through any network possible yet no matter how much he tries, the only thing he sees are the screen only flickering with static and white noise, a deafening silence in digital form.

He frantically typed a message for Lyla, his fingers flying across the holographic keys, but the message wouldn't send.

He tried again and again and again and yet no matter how much he typed, the answer is still the same: Nothing.

His shoulders slumped, and despair finally washed over him. The city, once a beacon of Terenos civilization, was a tomb, and he was its sole occupant. But he refused to stay down. He wouldn't allow the fear to consume him. He had to find his people. He had to believe that they had survived. Theyhadto have.

With renewed determination, Eryx decided to leave the ruined city. Surely, his people had relocated. They must have found another place to survive, another sanctuary. He remembered the network of pipes that once crisscrossed the planet, connecting different biomes and cities. He sprinted towards where the pipes should have been, only to find it, like everything else, broken and useless.

He stared at the ocean, the waves crashing against the ruined beach. It was a barrier, but also a possible path. He glanced at his bodysuit as well as his colour shifting emotion jacket, its adaptive fabric still shimmering with color, and took a deep breath. He would not be deterred. He jumped into the cold water and started to swim, pushing himself onward with each stroke.

He swam towards the horizon, the setting sun painting the sky in shades of orange and red. He swam with a quiet determination, praying that his sacrifice wouldn't be in vain. Surely, his people had survived. Surely, they were somewhere out there.

He had to believe they were alright.

Hehadto.

Well, hope you guys at least partially enjoyed that.

Look, I know that it isn't a novel experience to read but I did my best okay and while my best isn't enough, unless you have any better ideas, let me know in the comments below if you know anything for me to tweak it for an improvement, actually.

Well, anyway, as always...

Ciao...

Bye...
