In an unknown era.
Some random planet in the Universe.
A man with long black hair, smooth white skin, and black-as-night eyes was walking in a street that was full of destroyed buildings and markets.
The street had dead bodies with all kinds of different body shapes, genders, and ages littered on the street that the young man was walking on, such a sight would have horrified any sane person but to the young man walking on the street, such a sight was nothing new as he kept his indifferent expression on his face without any change on it.
Smelling the metallic smell that came from different types of blood from different types of species that littered the ground didn't arouse anything from the young man.
After walking for what seemed like half an hour in the same environment where nothing is alive he finally arrived in the center of this huge city, that didn't have a single being alive other than this young man.
Standing in the center of the city, the young man's eyes changed color from deep black to deep red, then he uttered in a voice that was too beautiful to be a man's voice as it could charm anyone who listened to it.
"Devour."
After saying this single word, a black whirlpool formed above the young man before devouring everything in the city, from the dead bodies to buildings in the city, till nothing remained except for an empty area with nothing to see for millions of kilometers around him.
Feeling that his job is done, he turned around and continued walking searching for a new place with new people to do the same thing thereafter just arriving on this Planet.
Following behind the young man was the only living being in this area that the young man allowed to live.
Feeling the movement behind his back, the young man didn't bother to look behind and continued moving on his way.
While walking, he remembered something.
Remembering something unpleasant in his head made his usual indifferent expression twist into a scowl before returning back to normal, letting out a sigh.
He turned around to the person following behind him from afar.
"Come here, I will take care of you," just like that he gained a companion to accompany him on his mission in this Universe.
~~~~~~~~
At the beginning of the Universe, dozens of races were born to inhabit the planets and galaxies that filled the Universe.
After a long passage of time, the races evolved and begin interacting with each other until, there were constant wars between them, due to the limited resources and the clash of interests, which lead to a lot of bloodbaths and destruction.
This situation continued until the Universe gave birth to someone special to end all the wars.
The Universe wanted to return the Universe to its former state where there was harmony between the races, gave birth to an existence under its control that should follow its will, and cleanse the Universe from the filth that is inhabiting the Universe.
This person that the Universe gave birth to, was someone with a special ability to devour all the filth of the Universe and the ability to judge them and see if they were pure-hearted or not, if they were then they were allowed to continue living, if not then they should be immediately devoured and used to help that entity grow stronger.
As the Universe is vast and filled with vast numbers of races, the entity born kept true to his mission, by annihilating races and a lot of people who are not pure-hearted like the Universe programmed him to do, and by doing so he kept getting stronger than when he was just born.
As the days passed, then the years and centuries. Millions of years passed like that.
He who was born with no name was nothing more than a dog put on a leash by the Universe to exercise its will.
A being whose power reached a terrifying level that could threaten even the Universe if left unchecked.
A being with the ability to annihilate all life forms in the Universe.
But a being with no Will, a being who knows nothing except for destruction and devouring as its job.
Continuing in his job for millions of years, his name got famous and a lot of titles and nicknames symbolizing him appeared in the Universe.
Emissary of Death
The Devourer
Ruler of Blood
Annihilator
He got all kinds of nicknames during his time terrorizing the people as the people saw him as a plague or a natural disaster, as all those who stood in his way were annihilated along with their planets.
Although from his point of view, he was doing nothing wrong as this was his mission and he didn't do much, since he doesn't have free will to do what he wanted, he just kept going in his monotone life.
But as the Universe thought that the status quo would remain like that, a being from outside the Universe interfered by doing one simple thing, a very simple action that had a terrifying consequence on the Universe.
It removed the leashes that were binding this being to eternal servitude.
It removed the shackles that were binding this being from its birth.
The being who had no free will before, but only had a vague understanding of the concept of Free WILL from all the memories he had seen when he devoured other beings.
Finally understanding his role as a dog all this while with nothing more than one purpose which was devouring the filth in the Universe, he exploded with rage.
The day his shackles were broken, the Universe trembled, as it felt his wrath and it knew that there were going to be severe consequences.
The Universe wanted to immediately throw him outside the Universe but it couldn't as his level was much higher than the Universe, after spending all those years Evolving, he simply reached a terrifying level.
So, all the Will of the Universe could do was watch How he unleashed his wrath on all life forms in the Universe.
Sometimes he annihilated all, and sometimes he left only the pure-hearted being as the feeling of his mission for the past millions of years still affected him.
Being freed from his shackles, the being immediately unleashed its wrath on the Universe as a whole, instead of judging, he devoured all the races and only left a small amount of them.
After devouring all races, he was left alone again without purpose after quelling his anger, not knowing what to do next, he decided to go to digest all the power he gained and to give his body some rest after all these millions of years that he spent wandering around fighting and devouring.
After wandering for more time, he arrived on a blue planet that was just born recently and was stationed on one side of the Universe, he just annihilated all the lifeforms on the planets before making a Coffin for himself to sleep in.
After what seemed like millions or maybe billions of years he woke up to a startling sight of this Planet's Evolution.
