Justice League -Chaos Creator- (Rimuru × Justice league)

A/N: I'm not supposed to introduce Nightwing yet. I've already fixed the chapter where I mistakenly mentioned Nightwing instead of Robin.

Robin sat in the Batcave, intently watching the live feed of the chaotic battle unfolding in Metropolis.

He wanted to go and jump into action, to provide whatever help he could.

Why can't you trust me on this one bruce?

It's not that bruce doesn't trust him, he was afraid to lose the said child if caught in a clash of world ending monster.. He wasn't ready.

In a way, robin misinterprets his overprotectiveness into looking down on him because of his young age.

But as he prepared to suit up, the Batcave's surveillance cameras flashed an alert.

The screen displayed a group of heavily armed individuals moving cautiously near the hidden entrance of the Batcave.

Robin's eyes narrowed.

The Batcave's concealment was nearly foolproof, but something about this group was unsettling.

When the camera zoomed in on one particular individual among them, Robin froze.

"Thats so unlike of you, joker" muttered robin as he prepares himself.

Meanwhile, Cyborg flew at high speed toward Metropolis, to assist superman and the others.

But before he could get far, a shadow loomed over him, and a sudden force slammed him out of the sky.

"Graaagh!" Cyborg roared in pain as several androids piled onto him, twisting his mechanical arm.

Beating him up, stabbing, but the blades can't penetrate his hard armor.

His systems whirred as his arm reshaped itself into a massive gun with a blade.

With a powerful sweep, he struck back, slicing through the nearest androids and sending the rest sprawling.

The remaining androids quickly regrouped, their designs sleek and unique.

Some bore oversized hips and legs, clearly built for speed and, wielded arm-mounted blades that gleamed dangerously.

A second wave approached, this one armed with high-powered guns.

Their silver, uniform appearance hinted at a sophisticated creator.

All the androids moved in sync, responding to the subtle gestures of a single figure.

From the back stepped Tony Li, adorned in advanced, cutting-edge armor.

His expression was calm but laced with irritation as he observed Cyborg struggling against his creations.

"I hate working with egomaniacs like Luthor," Toni muttered, clearly dissatisfied with his current alliance.

Still, his focus remained on his current target, he directed his machines forward.

"Let me vent my anger in you, Metal Boy"

Cyborg grunted as he activated his comms, his voice strained but calm. "Sorry, Batman. Looks like I'm going to be late. One of your acquaintances decided to drop in at the worst possible time."

Something was wrong, the comms buzzed in static. The connection was gone.

"Great"

From his vantage point, Tony Li smirked, his voice amplified by the speakers in his high-tech armor.

"Only a fool would want to be a friend of that self-proclaimed man of fear, he disturbed my business and cost me billions, its time to collect some personal debts, i want all of the justice league's life at my hand"

Tony raised his hand, signaling the androids. "Destroy him."

The androids sprang into action, their movements precise and mechanical.

The speed-focused units darted forward, their arm-blades slashing at Cyborg with blinding speed.

Cyborg countered with his arm cannon, blasting one android into pieces, but the others quickly adjusted, circling him like predators.

The gunner units opened fire from a distance, forcing Cyborg to deploy a defensive energy shield.

He gritted his teeth as sparks flew, his systems warning of rising power consumption.

3 Months Ago

After the invasion from metropolis, justice league was created.

Luthor's plan never changed. His goal remained the same.

Looking at the flying hero, he couldn't help but think how it all started, why he hates him so much.

"Yes... It was because of that"

Recounting their conflicts over the past years.

And finally. That very memory that rest's last at the back of his head.

"Thats right, it's because of that"

So back with his usual routine, a parademon found it's way to him.

Disposed of, experimented, was used as a weapon.

And with the new team of heroes, he can't just go out there advertising himself in public fighting superman.

He needed something, this time different.

All the times he fails against superman, idea's scrapped coming to life.

And with a sample of blood from a deceased alien of the same race as superman.

He was going to make a living weapon.

When the next day came, an unexpected guest came to visit.

He came knowing everything, a dangerous person.

There professor Ivo stood, that day an alliance was created.

There was distrust between them, question lingers that the kther party won't answer.

"How did you know about the samples?"

"How did you know about my plan-

My vault pass

My...

..

That was enough questioning to a man who doesn't even want to speak.

A month had passed, doomsday project was on the making, along with the revised amazo, renamed to A-1 Doom.

Then professor ivo invited another power from a dark city, tony li, the big boss of neon dragon triad.

"What is he planning? That man"

A question directed to Ivo.

"Just watch how things will play"

Though thanks to the triad, the plan progresses earlier than planned.

And now it's time for the big operation.

Doomsday and A-1 Doom was released in the middle of the city where superman are.

"I will be going on my way now"

Professor Ivo dissaoeared, mounted in his new monster.

"See you around"

And before going on his way also, one more input command -Make sure no civilians are harmed-

Luthor made sure he puts it on these two bulking monsters.

A mission or objective, their only target is superman and the other heroes.

After that, luthor flew away in the night as chaos emerged within the city.

Professor Ivo, riding the back of the sub monster he created he called lykan.

A wolf like creature of horror, filled with sharp bones as weapons with physical power not inferior to doomsday.

Running ahead and jumping at the mountains.

Ivo sat at the back, a smile.slowly growing on his face as he mutters on his watch "8362 - Delete All Prompts"

.... "New Prompt, Destroy Everything"

Command in the head of doomsday and Amazo was re-written.

"Oh luthor" he muttered, sounding dissapointed. "Well... It doesn't matter"

Looking at the bakery from a distance, ivo said "Even superman puts in effort hiding his identity, oh what a carefree person you are, new hero"

Meanwhile, tony li wears the suit gifted by lutbor to him and a bunch of robots from Ivo.

"Follow the plan and you will get the bat"

Was the only words that luthor left for him.

And so he prepared, it was time to ambush a certain cyborg.
