A new X-perience

He kept sitting on a sofa, in his room, a room with excellent memories, he still kept the half sock in the corner of the room where Papyrus left letters telling him to remove the socks, he gave a sad laugh, his brother did not know but he did it just to see if Papyrus still cared, if he still cared about him, his sloppy style was always common for the monsters, believing he was just a lazy one, but nobody cared, they liked the bad jokes and of the fake smile he always had, a smile to hide everything that was going on in his mind, he slowly put his hand on his face, while his eye shone, the child, that demon did it, he really managed to destroy everything he cared about, his kind actions hiding a sociopath, he pressed his face in anger, he had to kill his own friends because of that bastard, he had to kill his own family....
He had become a monster, Papyrus tried to kill him, but he could still see goodness in him, even so, he would never understand, his innocence was used against himself, and Sans....
Sans didn't even notice how he himself was used....
And when he tried to fix everything, what happened? He succeeded, he managed to take the human soul for him, but at what cost?
He could be powerful now, but now, he didn't know how to rebuild his world, he didn't know how to use the Overwrite button, because of that, his world was now empty, with nothing and nobody, and with one of the brats accompanying him all the time, he tolerated that asshole for a while, but he knew he wasn’t trustworthy, even though he knew Ink and saw a possible friend, he was very foolish, and he didn’t want to help him fix the damage done, shit, he didn’t even tried!
It irritated him deeply, that bastard of paint just tried to give him moral lessons about friendship and leaving the past behind.
He says this because it is easy for him, the guardian of the Multiverse not only works alone but the only thing he cares about is himself, he is a hypocrite who says he brings sympathy when HE DOESN'T KNOW HOW LOVE!
Alone he had time to think, he screamed, he cried, he sobbed, he cursed.
He didn’t know what to do, he was desperate.
So Nightmare showed up, he says that all my negative emotions caught his attention, saying that he "never saw any Sans with so many negative emotions", he laughed at my problems, I would have killed him, if I hadn't heard him, he felt that by my "tasty" feelings he would give me a chance to restart my Universe, this offer was too good to pass, so I listened to him, I would have to make everyone suffer in all the universes he took me to, I would have to create as many negative feelings as I could.
Sadness, anger, hopelessness or whatever we prefer not to feel.
I would have to sell my soul, but I accepted, all to correct my past mistakes and rebuild my universe little by little.
If regret killed, I would have been dead for a long time, but I didn't stop, and the worst, I started to like it, with every universe I visited, I made people suffer, I killed their loved ones in front of them, tortured some just for the sake of it, I slaughtered entire villages, and destroyed entire cities, and each time I became better, each time, I hesitated less, and each time, I felt more alive with each stab I took, each house I burned down, I felt more pleasure.
I knew I was going crazy, that I would lose someday, but for my home, for Papyrus, it doesn't matter, it is necessary.
And better, I got rid of the idiot in my head, I got it after a few more services for Nightmare, he removed Chara from my soul, now there is only me, and me only
With each Universe that I caused despair, I managed to rebuild my universe more and more, Snowdin is almost completely recreated, I just need a few more trips, some more massacres, and I will be able to complete the holes.
He thought as he stretched out on the couch, he slowly got up and walked around the room, she was not the same as he remembered, but it was good enough, he slowly opened the door and walked down the frozen street of the corrupted Snowdin, a black covered creature of a dark goo he kept looking at the half-formed Christmas tree, keeping Sans trademark smile, while his tentacles slowly speculated the tree.

"You know, i never understand you Cross...."

Nightmare said with his back to Cross, that was arms crossed with a raised "eyebrow" at him

"Why try to recreate something? Why not make the universe your image? Or something you think is better?"

Nightmare looked back, keeping his back to Cross, to see his expression as he answered, Cross maintained his posture, and slowly maintained quiet, looking up to the unfinished tree.

"I just.... Want things go back as they were..... Without a human to meddle in our lives, to be able to live in peace..... and to correct my mistakes...."

He would say while his face would keep his expression neutral, he knew that explaining to Nightmare the good things about having a family were useless, Nightmare was a diabolical being who only cared for himself and fed on the disgrace of others, but he didn't want to stay on his bad side, so he answered sincerely.

"Thats patetic, even now you have all the cards to make whatever you wish, and you just toss them aside."

Nightmare said looking at him with one mocking smile while Cross maintained one neutral expression.

"But I don't care, if I get negative feelings and that you keep part of your agreement, I'm satisfied"

Cross walked slowly and stopped beside Nightmare, turning to face him, the shadow creature kept facing the Tree, but with its eyes fixed on its counterpart

"If you came, you obviously want something, what should I do?"

Nightmare just smiled even more at the deduction of his companion

"Smart boy, yes i have another job for you, knowing your specialties, I knew you were the right Monster for the job"

Ignoring the nickname given to him, Cross nodded, Keeping his smile, Nightmare teleported them, both disappearing from Corrupted Snowdin.

Both then appeared on top of a hill, looking at a small village, in which one could see many... Horses?
Yes, Anthropomorphic Horses.....
All with diffrent colours, sizes and all with tattos on their flanks....
What else? Will sunshine come out of their asses aswell?
Monsters came in all types, shapes and colors, but he had never seen anything like this...
Nightmare was leaning back against a tree looking at Cross who was looking around

"You know the deal, kill, but not everyone you come across, make them suffer, torture as many as you can, make more than just physical pain."

Cross 'crossed' his arms (Batum-tss) and nodded, while looking at that colorful and happy village, it was annoying see them, jesus, look at them, acting like everything is wonderful, like nothing is important, like the world is a party, where do they think they live? a fairy tale? he looked at Nightmare.

"I understand my service, and it will be done, however, what kind of alternative universe is this? I thought it was just our alternative versions, not... this...."

Cross made a sign with his hand pointing to the village, Nightmare looked and disgusted when he hit his eyes they came into contact where Cross pointed.

"The Multiverse is much wider than you think idiot! It is not only alternative versions of our worlds, but also alternative versions of thousands of others, Dream and Ink protect a tiny part of the multiverse if you were able to see the size of it all, you would know we are like a grain of sand in one entire desert! Universes are always created and destroyed, is a constant struggle between creation and destruction, there's all kinds of universes that you can even imagine! believe me, I saw one were humanity governed the entire galaxy, another were Monsterkind never even existed, another were there was teddybears that spread love, and this is one of them, his positive feelings are so powerful that they reach our part of the multiverse with its 'harmony', it's annoying, it's disgusting, that's why I want to that you get rid of it, hell, destroy everything if you want, just getting rid of all that positive energy is going to be a huge favor that you will do to me, here it doesn't have a balance like other universes, here, in the smallest of chances, instead whether corruption reigns, or is in constant confrontation with creation, here, Harmony is dominant, and 'happiness' and 'prosperity' are everyday things in this shit."

Cross was surprised even though he didn't show, by Nightmare's explanation / ranting, he was not someone you would expect to lose patience easily, and he understood a little more about the Multiverse, it was something really vast and difficult to understand, but he nodded to Nightmare confirming, the former just smiled, disappeared, teleported away, Cross would look at the village and summon his giant sword and rest it on his shoulder, and slowly walk to the small village, he had a job to do

Author's Note

Finally! I had enough inspiration to do this chapter! I love Underverse and the concept of transportation in the multiverse he is looking to rebuild his universe, now he is going to cause chaos in Equestria! Did I do something wrong? Orthographic error? ideas? I am all ears! Criticize me! Thank you and peace!

Making an X-ample

Cross would slowly walk down the muddy road, he would look where he came from, a forest, a very dark forest, and looking at the village, he would see how colorful it was, it was almost ironic, he kept walking, and he would look at the entrance, a sign, "Ponyville", he chuckled low to himself, obviously, what should he expect from a happy horse village?
He would think while entering the city, he obviously drew attention, in a city where everything and everyone is colorful, a black and white hooded figure with accessories of the same color would be very striking, but something that surprised him was that immediately after they hit his eyes on him, everyone went into what looked like a trance, he stood there, looking around, everyone was staring at him, all the noise had stopped, it was a little creepy he thought, and suddenly, a Mare, (What he could recognize that it was a woman) screamed in fear and ran away, everyone followed the example, screaming in despair and locking themselves in their houses, taking their children and hiding, smart in their part, this was going to make his job a little harder.

Twillight was in her friendship castle doing her normal routine, reading and studying aspects of friendship, after a trip to the kingdom of the Changelings and learning their culture, she had given many books teaching Changelings about friendship, while in return, king Thorax gave her several books telling about the ancient Changeling history and culture, it was fascinating, she read one after the other, learning all the leaders who passed through their hive and their accomplishments, and also seeing many mistakes and lessons passed on to their minors on how to steal love, she knew it was part of them in stealing love, but seeing how their culture progressed to the level they reached when invading her brother’s wedding was amazing! she could continue her reading if it weren't for screaming outside her house, she immediately closed her book and ran to the door, only to receive the Elements of Harmony desperately entering inside and slamming the door shut, locking it and sliding in the door back to back, all sighing with relief.

"Girls? what is happening?"

They all looked at Twillight and all smiled and jumped over her, all group hugging her, she was surprised by the sudden action, but hugged them all back.

"Twillight! Darling its so much good to see you fine!"

Fashionista said, with Rainbow nooding agreeing as they left the group hug

"Yes! We were worried you stayed outside!"

Twilight turned her head, raising a confused eyebrow.

"What? why?"

Fluttershy hid behind her mane looking scared while looking at her.

"A Monster have come to Ponyville!"

Twilight's eyes widened at the revelation

"A monster in Ponyville?!"

Applejack scratched the back of her neck in an embarrassed way

"Well.... it looked like a monster...."

Twillight's face calmed down and she showed a mocking smile

" 'Looked like'? I don't belive in you..."

Rainbow Dash, then took Twillight's hand and dragged it to the window and pointed to a figure on the street, Twillight looked closely, the street was completely deserted, the houses had their doors and windows fully closed, for a village as busy as Ponyville being like this was very rare, but when she noticed the lonely figure walking between the streets she could only be more nervous, the figure was totally covered by clothes with black and white accessories, her huge scarf around him thrown back formed almost a cover effect, but that wasn’t what scared him most, nor was his face covered up to his hooded nose, no, what scared him was the huge knife gently resting on his shoulder, he was in a relaxed pose, with his other hand on pocket, even so, the aura he gave off was startling, Twillight slowly looked at the other elements of the harmony.

"Ok.... He is a bit scary...."

The Multi-colored Mare sniffed

"A bit?? He is carrying a MASSIVE KNIFE! That guy is not a bit scary! He is terrifying!!"

As they continued to discuss whether the figure was scary or not, Fluttershy slowly went to the window and peeked out, and noticed a Colt staring at the knife figure with fascination, she then horrified put her hands to her mouth and looked back at her friends debating

"Guys...?"

"But he must be only lost! You don't know if he is dangerous or not!"

"Guys?"

"Listen to yourself Egghead! A guy we don't know armed came here! He obvious-"

"GUYS!"

Everyone flinched a little with the loud cry of their quietest friend and immediately ceased their arguments, seeing that she screamed, Fluttershy hid behind her mane and returned to her shy state with a low "Sorry" before turning and pointing at the window, they all huddled together to see and were in shock when the knife figure stabbed the boy.

The world seemed to stop, and everything seemed to be silent, as the figure impaled the boy with his huge knife, they could clearly see the parents at the door looking at the scene with expressions of shock and horror.

"CAKE!! NO!!"

The hooded figure would look at the screams, it was Mare who clearly his mother, the figure did something that horrified Mane Six.
He chuckled....
No... He started to burst out in laughter at the scene, before return the gaze to them, they could see only the eyes of the figure, those scarlet red eyes piercing the souls of the parents of the little colt.

"Y-you Monster! How could you?? HOW COULD YOU???"

The figure with a quick movement, removed the knife from the colt, ignoring the desperate parents, however ...
Colt didn't drop dead....
No....
He stood, still...
The parents were oblivious, and how could they not? hadn't their son died?
Then Colt slowly turned towards them, his skin had become completely pale, his face had a huge red X in it, and his facial expression was nonexistent.

"Yes... Very perspective of you... i am a monster, however... don't worry..."

The figure would say rubbing his hands on the shoulder of the completely paralyzed colt, his white big smile being completely visible under the hood and making the couple terrified.

"Your son is fine with me.... i can't say the same about you....

And when he said that he slowly stopped scratching the colt's shoulder, and snapped his fingers, and with that, red transparent knives appeared on top of him, all pointed at the couple, and pointing the finger he snapped at the couple, the knives flew towards them, with both hugging and screaming in horror.

A massacre, it was the only thing that could be described, Fluttershy looked at the entrance to Ponyville in flames, panic screams, explosions and death, she had never seen anything so horrifying as that, the great center of the city, which before was a symbol of beauty, pride and peace for the Pony's, it could only be described now as ashes, there was nothing left, she was paralyzed with fear, she looked in the streets, the cadavers thrown were numerous, Stallions, Mares and Colts, none were spared, who could do such an atrocity? not even the Crystal Empire tyrant king Sombra did anything as close as that.

Then she saw, a Stallion desperately crawling, a severed leg, leaving a trail of blood, she just looked horrified, he had tears streaming from his face mixed with dirt while behind him a figure she could say came from the darkest pit, the figure was completely covered in white and black clothes, wearing a hood and cape that covered part of his face, what was left that could be visible where his scarlet red left eye and shinning purple right eye, he walked slowly behind the Stallion, who suffered to find the strength to try to escape from the creature that followed him so calmly even in such a horrifying situation, he then with a sudden kick, threw the Stallion rolling and falling on his stomach grunting in pain.

"Disgusting"

He would say as he stopped in front of the Stallion that he put his hand on his belly, while blood dripped from his mouth, he looked at the face of his figure, fear, it was the only thing the poor man was feeling at that moment.

"W-w-what a-a-are y-y-you....?"

The Stallion would ask while spitting blood on himself, the hooded figure would just stand there, looking at him, he would then raise his huge knife, and say a sentence that would be stuck in Fluttershy's head for the rest of her life.

"I AM THE X-EVENT"

And then the knife would go down hard on his victim's head, cutting his head in half, his face paralyzed with fear, with a tear stopping in the middle of his descent, the figure would then place a foot on the victim's shoulder, and the would throw it on the floor, using the momentum to remove his knife stuck in the poor young man's skull, he would then slowly look to the side, where Fluttershy hid, his eyes shining in the bloody night, as if penetrating deep into poor Pegasus' soul, she then , flew, she flew as fast as she can, took off from her hiding place and flew anywhere, she didn't care where, she just wanted to get away from him.

He would look at the yellow pegasus flying away, he would shrug, it’s just one, it wouldn’t make a difference, he would look at the street putting his knife to rest on his shoulder, he would look at his work done, he could still hear the screams of despair and pain, a lot of pain, he had modified the code of some of these Pony's and made them attack each other, brother killed brother, father killed child and son killed mother, if that doesn't cause many negative feelings he doesn't know what it would cause, if there is any monarch in this place, he would probably hunt him after that, but he didn't care, these 'zombies' would distract and draw a lot of attention, he would slowly walk to another path leading out of the village and in the same direction from where the pegasus went, he smiled while walked away from the ruined village, that must have changed everything, these 'pets' will learn what the real world is like, and as they don't deserve the good life they have, they won't escape Cross.
