In the far past, within the depths of where multiple voids exists there lays to be a entity that is not relevant to dimensionality on a infinite scale itself as this being was existing for a short amount of time due to its overwhelming presence was linked towards a chaotic and twisted mind that exists beyond comprehension itself as he was seen as a forgotten being deemed to never exist in any sort of dimensional state of appearance as he lacks of it entirely.

Bound by this, he was not aware of his monstrous self-existential state of existence would turn out like a monochromatic type of entity that's not even a sans but something way worse itself as his existence was known to be the worst of them all as some say that he shouldn't be existing in the first place where the problem starts off that he didn't even existed as his body lacks on so much that his existence consumed itself being a twisted figure that none can even fully understand its potential, goals and motives.

It had no name, it had no physical body, it was nonexistent itself as the nullified presence of this being echoed the existence of many dimensional voids that exists across space and time alike as its forgotten existence lay many on waste itself as many tried to destroy him but none had even succeeded on destroying him so many forgot that he even existed but, many couldn't even ignore his existence as some found it odd that nothing can even damage him as he was a soulless, codeless and ageless being with no doubt of life.

His mind was silent, his body was still like a stone as his conceptual body was nothing to even matter for the best as this being was something odd and that oddness was filling his null-type of mind that not even some deities can even understand what he was even thinking about as some didn't even notice that he wasn't a hero but a evil being that seeks to destroy the concept of good as this being was not bounded by creation itself as colors couldn't even effect him as he was not colorful but the dull of colors washed his good away like the hopes an dreams many had.

His existence was incomplete and yet so imperfect to the point where he was meaningless and useless to where he didn't want to exist but the grunting of pain, agony and despair pissed him off anyways as the pain was silence as all he thinked about was silence echos of his mind that was not heard by anyone.

But can be heard if he wanted to really as the despair of his body was leaking out nonexistent substance from his own eyes not thinking, not doing anything but floating around in the middle of a grey texture type of void as he just created with his presence alone as it was the destruction void that was a monochromatic on coloring just like himself as the void like himself lacked dimensionality on the fullest but still stable on having a physical body that transcendent dimensionality on a infinite scale.

He later came up with his name when the void was completed but he was uncompleted as he called himself "Entity 0" a colorless being with emotionless factors of behavior and attitude that would wash the good from anyone looking at himself for too long would've been a stare of death itself as he is always active but quickly and shiftily knowing that good for him is another waste of time itself and by this he would kill the good on anyone that he finds too good to exist as his colorless existence stayed... nonexistent.

Right now, he stares at nothing, perhaps at the "viewers" and says this

"I will make sure you insufferable beings will perish before me! You pathetic heroes of your fantasy tales will be ruined by nonexistence!"

(Continue the rest of the story. But warning, if you're an hero, he will try to erase you to be nonexistence.)
