Prologue

(Author's note: The following story contains characters from an Undertale AU of my making: OmniTale. Undertale and all of its characters and concepts belong to Toby Fox, the original creator of Undertale)

(This story is going to be based on a Twitter user's yet to be published story called "Sonic Execution". The Twitter user is named DavidArts, otherwise known as @imlazyashecklol) (please do check his art, it's really amazing)

(Without further a due, let us begin with the origins of this story)

Thousands of years ago, when the system of the Omniverse was still at its infancy, three kingdoms were locked in a devastating war. A war fought for the sake of land and power, a war sprung out of hatred and animosity towards one another.

For ten generations, these three kingdoms fought their war; spreading their destruction upon the Omniverse. Nothing was left without being reduced to ash by their hatred, no sentient life was spared from the devastation they brought forth.

Eventually, the newer generations became disillusioned by the hatred of the old generations, and the destruction that they wrought over multiple universes. They realized that if their war continued its course, then it will bring death upon all.

Including their precious kingdoms.

The rebellion of the newer generations against the will of their ancestors sparked a great revolution that did away with their outdated and corrupt leadership; giving rise to a new set of rulers that sought to rectify the destruction their ancestors' selfish war brought, to bring peace to all life forms that desperately sought it.

The result of the combined efforts of the three kingdoms to seek peace was the unification of all three kingdoms, where all citizens of the three kingdoms lived in harmony and love.

A unified kingdom that no longer pledged itself to war and chaos, but to serve and protect not just its subjects; but all beings that existed throughout the Omniverse.

The new found purpose of the kingdom gave birth to a legion of elite and powerful warriors, so powerful that no mere mortal can ever fathom to reach their power. They were called the "Legion of Peace", a legion comprised of powerful warriors whose sole purpose is to preserve life, and protect it from any dangerous threat.

They were the unsung heroes of the Omniverse, as the only ones who ever knew of their existence were the rulers.

Alas, for the next 6 generations; the Legion of Peace fought great battles against multiple enemies that threatened life on the Omniverse. With each passing generation, more promising warriors came and left their marks on the legion, becoming legends amongst the Omniverse, with their stories being passed down as if it was folklore.

Alas, with the 7th generation of these warriors; three of them stood tall and mighty amongst all others.

Gaia, the great warrior of nature who could bend nature's elements to her will; making any weapon she desires.

Gaster, the warrior who held vast knowledge of the Omniverse, though not unlimited. He was a renowned scientist who greatly contributed to the kingdom's advancements, and a man who possessed devastating power. (Once, he was unable to control his power and almost destroyed a universe, had it not been for his comrades' intervention. With his comrades' help, he was able to take control of his power)

And Asgore Dreemur, the kind and just warrior with an unbreakable will. His ability to manipulate fire and amplify its destruction at will gave him the title: "The Agni King".

These three warriors quickly rose in the ranks, immediately gaining the respect of the other legionnaires and the favor of their rulers. Together, they led the Legion of Peace throughout various tribulations for the sake of the Omniverse.

All seemed well for the inhabitants of the Omniverse and its guardians.

However....that period of glory and peace became short-lived, when an ancient evil was reawakened once more.

The three warriors caught wind of a group of cultists attempting to reawaken Armageddon itself. Through well-thought out plans and strategy, thanks to the Cultist's knowledge of who these warriors were; they were able to buy themselves time enough to finish what they started.

By the time the warriors tried to stop their ritual, it was already too late.

The wraith of darkness, a demon who seeks nothing but to drink the blood of all mortals, was reawakened.

It was Zalgo, the King of terror and despair, born out of the flames of hatred and evil.

Zalgo immediately declared war on all of mortal kind, on every single living creature that lived in the Omniverse. He made the terrible promise of coloring every single battlefield red with their blood, also promising every mortal that they will suffer his terrible wrath, his vengeance for the humiliation he suffered eons ago.

Zalgo had no interest in conquering the Omniverse and its subjects, but to eviscerate each and every living being to satisfy his bloodthirsty wrath.

Thus marked the beginning of the most catastrophic war that history has witnessed, with billions upon billions of innocent beings suffering under the cruelty of Zalgo. The unified kingdom, daring to stand against Zalgo's omnicide; suffered greatly from Zalgo's attacks, with its rulers killed and its army slaughtered senselessly.

Even the Legion of Peace, the most famed warrior unit, was massacred.

All but three remained, who could stand against Zalgo's terror.

Gaster, Gaia, and Asgore.

But even they did not fare well.

In a battle that would determine the fate of the Omniverse, the three worked together in order to strike down Zalgo once and for all.

After hours of brutal fighting, Asgore was the one who finally struck down Zalgo. His armies, which were spread across the Omniverse, were reduced to dust as a result of their master's downfall.

But...at what cost?

Gaia, the warrior of nature, was senselessly slaughtered by Zalgo.

Gaster, his longtime friend ever since he was a child, was banished by Zalgo to a realm beyond his powers; forgotten by every single living creature save for him.

And his family.....

He lost his family.

The aftermath of the catastrophic war was harsh, as no competent leader was able to rise to rule the fracturing kingdom, leaving the kingdom vulnerable with little to no resources to help its subjects. Thus, a power vacuum was created, and with the lack of food and water; tensions flared between various opposing factions within the kingdom.

All of this tension eventually exploded into a bloody civil war, which completely decimated the once proud unified kingdom. All of its subjects, fearing for their livelihoods, scattered themselves across the Omniverse; bidding their farewells to their homes where generations of their family lived.

Thus marks the grim end of the proud unified kingdom, and the proud warrior unit known as the "Legion of Peace".

But.....Gaster's story has not yet ended.

(Very important note: Zalgo is a creepypasta that belongs to an internet user called Goon Schmorky, who uploaded it on a website called SomethingAwful)

(Zalgo's actual origins are unknown as of now, this version of Zalgo is an interpretation of mine)
