The Backstory

# Chapter I

In the beginning there was nothing, there was no world until that one appeared. Undertale, a world full of monsters, a world of three paths, genocidal, pacifist, and neutral. With the creation of this world, a person was also created, a person responsible for security in this world. It was supposed to keep the player's gameplay in complete "balance", which meant that his job was to eliminate any glitches that appeared on the road, so that the player would not find out that the game was unusable. He is called Great-God. In the beginning there was nothing, nothing but the Great-God. From the beginning of its existence, he knew what and for what purpose it was necessary to do. During the first seven seconds of his existence, the Great God created the whole world, he created words, he created everything that was in it and what was supposed to go to him, he knew that certain people would be sent to him who need to be taken care of, and show them the way to "enlightenment". Already on the same day, the Great-God was obliged to intervene. Sans got stuck in his opening slot during the first test of the game, and the Great-God had to do something. The Great-God immediately moved to this glitch, and eliminated it, and the game itself replaced Sans with his copy. When the Great-God returned to his world, he placed Sans' body on the grass, whose body underwent changes. After two minutes, Sans opened his eyes and looked at the Great-God. The Great-God waited patiently for the first word of his new son. Sans stood up after a while, and uttered the words "Here I am.". The Great-God approached Sans and asked him five questions. "Do you know why you exist?" said the Great-God. Sans stared directly at the Great-God denied. "Do you know whom you are to serve?" asked the Great-God. "I don't know what faith is." Sans said. "Do you know what your will is?" asked the Great-God. Sans denied it. "Does your view matter in society?" asked the Great-God. Sans denied defeat again. "Are you alive?" asked the Great-God. Sans thought about the question for a moment. Finally, he uttered the words "I don't know." The Great-God got drunk on Sans, and gave him the name "**Hundred**", then left and entered his chamber closing the door made of steel.

# Chapter II

On the same day, the Great-God had to intervene once again. As soon as he sensed that the peace of the game was threatened, he went to the place of the fault as soon as possible. Sans got stuck in the texture of the stone, from which he could not get out, and the player was about to reach this place. The Great-God took over Sans, and the game replaced that character with a copy of him. The Great-God went with Sans to his world. The Hundred were no longer there, so the Great-God could continue. Great changes have taken place in Sans' body, his bones have changed their natural color to something that should not have happened at all. When Sans woke up, the Great-God was already prepared. The moment Sans opened his eyes, the Great-God asked him questions. "Do you know why you exist?" asked the Great-God. Sans denied it. "Do you know whom you have to serve?" asked the Great-God. Sans denied it. " Do you know what your will is?" the Great-God asked. Sans denied it. "Does your opinion matter in society?" the Great-God asked. Sans denied it. "Are you alive?" asked the Great-God. Sans hesitated for a moment, but finally said the words "I think so." The Great-God named him "**Two Hundred**", then told him to follow him. The Great-God set off towards the "fountain of the future". Sans thought for a moment, then joined the Great-God. The latter, standing in the field, pointed to one of the trees, saying, "Do you see that tree?" Two hundred confirmed. The Great-God told 200 to use his abilities to knock an apple off a tree. 200 looked puzzled, but he took the challenge. 200 summoned his white short bone and threw it towards the tree. The apple fell as the bone hit the tree. The Great-God told him to go to the apple tree and eat the apple that fell to the ground. 200 agreed without hesitation, and went to the apple tree. Once he was centrally under the tree, he picked up an apple and began to consume it. When he finished, his rags changed into fabulous, beautiful robes, shrouded in curious patterns, other parts of his attire changed as well. The Great-God approached 200 and told him to go look for himself, as he was sure he would find him. 200 nodded, then set off on north. Right after 200 left, the Great-God returned to his chamber closing the steel door behind him.

# Chapter III

The next day, the Great-God had to go to Undertale once again to prevent an anomaly from ruining the game. So the Great-God went to Undertale, and note that Sans got blocked on his way to Snowdin. The Great-God took Sans to his world, and Sans was replaced with a copy of him. When the Great-God came to his world with Sans, it turned out that the color of Sans's bones completely changed. The Great-God patiently waited for Sans to wake up so that he could begin his routine of bringing anomalies to his world. When Sans woke up, the Great-God started asking Sans his routine questions. "Do you know why-" the Great-God didn't finish, as Sans interrupted him with "You're going to whine like that to everyone, Grandpa?" The Great-God ignored his disrespectful behavior, but before he could start his second question, Sans interrupted him again. "Man, I think you should start listening to what other people say." Sans said. "Why are you acting like that?" asked the Great-God. "Because you piss me off, dude," Sans said. The Great-God stared at Sans for a while, then called him "**Three Hundred**", and left for his chamber. Just before the steel door of the chamber was about to slam shut, Sans put his foot in the door, blocking it. "What am I supposed to do here? You brought me here and what? You're fucked up dude." Sans said. An unseen force pushed Sans out of the door of the Great-God's sacred chamber, knocking him down repeatedly onto the grass. When Sans got up, the chamber door was already closed. "So that's it?! Okay! You're going to regret this, old man," Sans said to himself before heading north. 300 wandered through the clearing, after which he came across a mysterious range of apple trees. The 300 decided it would be a good idea to move along this line of apple trees. After about four minutes of hiking, 300 came across a tree full of oranges, he thought it would be a good idea to taste one. "I don't think anyone will be offended if I pick one, right?". 300 was wrong. Just after 300 had finished eating the orange, a large beast of unknown origin attacked 300 and pinned him to the ground. 300 was stunned, a large crack appeared in his skull from the impact of the beast. 300 teleported away from the beast and said - "Oh you, from behind like a fagot?". 300 summoned several Gaster Blasters and took aim at the beast. The beast roared at him, clawing at his face, creating two wounds on his skull. 300 groaned from the boule, then fired Gaster Blasters. The laser of these Blasters hit the Beast, damaging it badly. The fight lasted for about 3 minutes from then on, again and again the beast dealt 300 damage, but 300 was not in debt, and finally subdued the beast by sticking a red sharp bone into the beast's grits. 300 stood for a moment, then said "So what? Was it worth it bitch?". The 300 was pleased with his victory, and moved on. After marching ahead for some time, he encountered 200 on his way. "Hey! Who are you?" 300 asked, standing behind 200. 200 turned around smiling. "Oh! Hello! You must be the new one. Father told me to expect you here." said 200. "Father?" asked 300. "I don't have a father." added 300. "You know, the one who brought you here said 200. "That old man?" asked 300. "You're bold, aren't you?" asked 200. "Was that supposed to offend me? If so, you probably failed, you're starting to annoy me too." he said 300. "As a brother, you should respect me, shouldn't you?" asked 200. "Brother? What have you been on? Are you high?" 300 asked with obvious surprise on his face. "So you don't know..." said 200. "Fuck off, I don't need to talk to anyone." said 300 indignantly, then shoved 200 out of his way and continued on his way. "Hey! That wasn't nice," said 200. 300 continued his walk along the apple orchard, ignoring 200. After a while, 300 disappeared into the distance, and 200 continued to collect his apples from the apple trees.

# Chapter IV

Two days after the creation of the world in which the Great-God lives, there were another anomalies to which he had to go. On September 17, he headed for Undertale immediately after sensing that the player's gameplay was in jeopardy, this time in Gaster's room. The anomaly was that Gaster couldn't appear in the room for the player to see, so the Great-God came to that room, took Gaster, and waited for him to be replaced by a copy of him. When the copy appeared, the Great-God headed back to his world. Once there, he set Gaster down, noticing some changes in his body, such as a change in the color of his bones, but there was one more thing that shocked the Great-God. Gaster was awake. Gaster could see all the way from Gaster's room to the very chamber of the Great-God. "You intrigue me, I must admit, but wouldn't it be better to use a shortcut?" Gaster asked. "You are the only one who has seen the path we always follow," replied the Great-God. "Do you know what you exist for?" asked the Great-God after a moment. " The meaning of our existence is not known to anyone, and it is not needed by anyone. If a living being does something that it is good at, and it makes it happy, then such a person will call this activity the meaning of life , I don't have it." Gaster said. "Then it will be you who will serve by my side," said the Great-God. "Then so be it." Gaster replied. The Great-God called Gaster "**G100**", and told him to go set up his lab in the village, then left for his chamber. "If it is God's will," said G100, and set off for the village. After some time, he got there, and noticed an empty stand made of wood. "There hasn't been anyone here for a very long time," G100 said to himself, then entered the abandoned and slightly dilapidated site. G100 looked around for the site, and noticed that here he could set up the laboratory that the Great-God had mentioned. After he finished looking around, he started cleaning up the site after the previous owner, he himself believes that there must be order in a site based on science and chemicals. The G100 also calls itself a perfectionist.

### Chapter IV [part II]

In the meantime, on the same day, the Great-God had to intervene once again, this time it was Sans, again. During the neutral path, Sans got stuck in a pillar texture in the Judgment Hall. As soon as the Great-God sensed that the game was again in danger of being ruined, he set out to prevent it. The Great-God arrived at the Judgment Hall as soon as possible and took the fault into his own hands. He waited patiently for Sans to be replaced. After this happened, the Great-God left for his world with Sans. Upon arriving, the Great-God noticed almost immediately that this Sans had suffered the most disfigurement on his body, but remained calm. After Sans woke up, the Great-God asked him five standard questions. "Do you know what you exist for?", "Do you know whom you have to serve?", "Do you know what your will is? ", "Does your opinion matter in soctiety?", "Are you alive?". Sans was silent the whole time, he gave the impression that he wasn't listening to the Great-God. "Do these questions matter?" Sans asked. Before the Great-God could say anything, Sans was already gone. The Great-God returned to his chamber, closing the steel door behind him. Sans wandered through the forest until after some time he came to a village where he decided to settle down for a while. Sans went into various abandoned rooms, looking for his favorite ketchup in a plastic bottle. After some time, he entered a room with a broken mirror, which Sans decided to approach. What he saw in his reflection changed the course of his life. A bright green number "**400**" floated above his right eye, and his eyes merged into one large eye. 400 hated the Great-God, for what happened to him, he picked up and broke the mirror by throwing it on the floor made of rotten wood. 400 left the room with a very angry expression on his face. He summoned his two Gaster Blasters and loaded them up. He walked around the village in search of his ketchup, shooting every building where he thought there was no ketchup.

### Chapter IV [part III]

In the meantime, the Great-God ordered a meeting attended by **Error100**, **Error200**, and **Error300**, as well as the Great-God himself. "Christ, you look like a different version of me from the past," said 300 to 100. "You see, sometimes it is. I'm sorry about your anomalies," replied 100. "Okay, shut up already," said 300. " "Gentlemen take it easy, why all the nerves? If Father wanted to see us here, it means it's important, and we need to focus on it!" said 200. "HE'S NOT MY FATHER, STOP CALLING HIM THAT!" shouted 300. " I am very sorry that this was not your plan for life, although it is God's will, said the Great-God to the 300. "I wanted us to meet here because you are the first three who had the opportunity to appear in this world as a new person," said the Great-God. "You are the first three brothers of madness," added the Great-God. "WHAT?! WHAT ARE YOU SAYING?! THEY ARE NOT MY BROTHERS, I HAVE A BROTHER, BUT YOU TOOK ME FROM HIM." exclaimed 300. "One Hundred, Two Hundred, and Three Hundred." said the Great-God, adding that they are the ones who will rule this world divided into three kingdoms. "You're starting to piss me off dude." said 300 with an annoyed look on his face. "I'm sorry this meeting was so short, but I have to get back to my business," said the Great-God, then disappeared. "Well, I guess that's it, huh?" asked 200. "I guess so." replied 100. "Would you like to come over to my house? We could get to know each other better!" said 200. 300 got up and said "Fuck you, I'm going home." then disappeared. "Actually, I can come over, I don't see why not." said 100. "Sweet!" said 200, then stood up and told 100 to follow him and set off towards his home. 100 got up and started following 200. In the meantime, G100 had finished cleaning up his new station, and was starting to prepare the necessary items to do his job. Once he had finished getting things ready, he began his research, which took him all day. Around 10 p.m. G100 decided to stop the research and go to rest, because he knew that his work would be long and hard. G100 took off his lab clothes and went to his bed upstairs. He finally fell asleep, which was made difficult by the fumes in the air caused by the experiments he had been doing some time ago.

# Chapter V

The next day was completely calm, the Great-God didn't need to intervene once, so he stayed in his quarters without showing himself to anyone. Around 10 am 300 passed by his chamber, and thought it was time to end it. He walked up to the steel door of the chamber, and knocked hard 4 times. "Open up old man, we need to talk." 300 said in a loud voice. No sound came from inside the chamber. "I said open." 300 repeated. Nothing happened. 300 got angry and summoned his Gaster Blasters, then dynamically moved away from the chamber door and fired his Gaster Blasters straight at them. His efforts were in vain, the chamber door didn't even budge. He growled in fury, staring at the chamber door. 300 walked away saying something under his breath. 300 went to 200's house, where 100 was also staying. 200 and 100 were just talking about the supposed appearance of a human in their world. 300 burst into the house by breaking down the door. "WOW DUDE, WHAT ARE YOU DOING?!" exclaimed 200. "THIS DOOR WAS REALLY EXPENSIVE!!" added 200. "SCREW YOUR DOOR, WE HAVE TO TALK." exclaimed 300 as he entered. "DUDE, DO YOU KNOW HOW MUCH I PAID FOR THEM?!" asked 200. " WHATEVER, YOU'LL GET YOURSELF NEW ONE. " said 300. " What do you want to talk about, actually? " calmly said 100. " ABOUT YOUR STUPID FATHER!!! " exlaimed 300. " HE IS YOUR FATHER TOO, DUDE! " added 200. " HIM?! HE IS NOT MY FATHER YOU STUPID SON OF A CLOAK!!! " exclaimed 300 while getting near 200. " WE HAVE TO DO SOMETHING ABOUT HIM!!! " added 300. " HE SAVED US, 300, HOW ABOUT SOME INTENT FROM YOU? " said 200. " INTENT?! FOR GETTING ME AWAY FROM MY LIFE?! I DIDN'T ASK HIM FOR DOING SO, WHAT IF I WAS SUPPOSED TO BE THERE AND ROT TO DEATH?! I AM SURE IT'D BE MUCH BETTER THAN STAYING IN THIS WORLD WITHOUT MY BROTHER NOW. " said 300, meanwhile walking around the house. " Listen, this isn't his fault that we've glitched. " calmly said 200. " BUT IT'S HIS FAULT THAT HE TOOK AS AWAY FROM OUR LIFES, DON'T YOU FEEL A LITTLE... I DON'T KNOW? FORCED TO BE HERE? I DIDN'T ASK HIM TO GET ME HERE, I WOULD BE WAY HAPPIER IN THAT STUPID ROCK THAN HERE. LOOK AT ME! I AM GODDAMN DEFORMED!!! MY BONES HAVE DIFFERENT COLOR, WHICH WAS NEVER MEANT TO HAPPEN!!! " said 300. " If it happend, then it meant to happen anyway. " said 200. " OH MY GASTER, AM I THE ONLY ONE THINKING PROPERLY HERE?! DON'T YOU SEE WHAT HE IS TRYING TO DO?! WHAT DO I HAVE IN COMMON WITH THAT FREAK ANYWAY?! " exclaimed 300. " You're his son, after all. " calmly said 200. " WHAT?! NO!!! I AM SON OF A GASTER GODDAMN IT!!! " exclaimed 300. " You won't change the way who you are, 300! " said 200. " It happend, you can't turn it back. " added 200. " OH?! OH?! WELL, WE'LL SEE ABOUT THAT. SO I GUESS YOU ARE NOT WITH ME ANYWAY?! " exclaimed 300. " Stop being afraid of who you are meant to be from the beginning, it won't change anything, 300! " said 200. " **WHY DO YOU HAVE TO BE SO FUCKING ANNOYING 200!??!!??!?! "** he shouted very loudly at him. " I DON'T CARE ABOUT EVERYONE OTHERS FATE, ALL I CARE ABOUT IS MY LIFE, WHICH WAS RUINED BY BRINGING ME HERE!!! " exclaimed 300. " IT'S NOT LIKE I CARE ABOUT THE OTHERS THAT HE HAD BROUGHT HERE, I DO NOT CARE ABOUT WHAT HAVE HAPPEND TO THEM. THE POINT IS THAT HE WILL JUST KEEP BRINGING HERE NEW PEOPLE, AND MAKE THEM SUFFER AS MUCH AS WE DO YOU STUPID SON OF A BITCH!!!! " said 300. Then someone stood up to the broken door, and with deformed voice said " *Ah yes, I know that. My body got really hurt during the way here, long arms aren't really friendly.* ". 300 turned around to the door really quick, with a surprise on his face, but still angry. " AND WHO THE HECK ARE YOU NOW?! " shouted 300. " *I just got here, I don't know who I am yet. I guess it is just an deformed version of you, but with a number 500 up to my right eye.* " Said 500. " OH GREAT, 100, 200, ME, AND NOW 500. I WONDER WHERE 400 IS, HAHA. " said 300. " *I'm so sorry, 400 is somewhere else.* " said 500. " AH-HA! I TOLD YOU, YOU FUCKING GREEN ASS!!! I TOLD YOU HE WOULD JUST BRING MORE AND MORE, AND WHAT?! I TOLD YOU IT'S GONNA GET WORSE, BUT OF COURSE NOONE IS EVER LISTENING TO ME!!! " exclaimed 300. " Look dude, we will not be against our father... " said 200. " THIS ISN'T YOUR FATHER ASWELL! 100, YOU ALREADY HAVE A FATHER, AND HE'S EVEN HERE!!! " shouted 300. " He is? " asked quietly 100. " YES YOU SON OF A GASTER!!! " answered 300. " SCREW YOU GUYS, I'LL DO IT MYSELF THEN. " said 300, as he ran out of the house. " *Well, hahah, it is something really upsetting about that guy, huh?* " said 500. " I don't know, he is just... maniac. " said 200. " *I am too, I'd love to cut your not existing veins right now, but it seems like I have better things to do at the moment.* " said 500. " Right, you look like... " said 200. " *Sadly, or not, I am the last normal one here which came here, the rest will be way~ more screwed up than me.* " said 500, as he was leaving. 200 sighed, and continued to speak with 100, which lasted until the mid night.

# Chapter VI

**Gaster**, mainly called **G100**, is known for his crazy, strange, senseless and even one might say... *maniacal* experiments on beings, entities and monsters. Well, no one opposed him, because no one knew that **Gaster** was doing such things in his underground *laboratory* in the first place. One ordinary day, no different from the previous ones, **Gaster** suggested meeting **Error!100** at his place. *"Sans, my child, I have something to ask you."* - **Gaster** said. **Error!100** turned towards him after a moment and said, slightly surprised - *"You? Is this a matter for me? We don't see each other very often, so I have no idea what I could help you with, dad."* **Gaster** thought for a moment, and he replied - *"Oh, it's really no big deal, I wanted to suggest meeting you at my house in the center, we need to talk."* **Error!100** looked slightly worried about the whole situation, and decided to wait a while for further developments. *"You're going to ask me what I want to talk about, right? It's not for now, it's not the right place... that's about it."* - **Gaster** replied. *"I feel insecure when you talk to me like that, Dad."* - said **Error!100**. *"Okay, I won't bother you anymore, kid, so will you come and talk to the old man?"* - **Gaster** asked, hoping that he would agree. *"I'll be there."* - **Error!100** replied curtly, then he looked around and **Gaster** was gone. Later that day, **Error!100** arrived at **Gaster** as planned. **Sans** didn't know what his father wanted to talk to him about, and he also felt a little anxious. *"You wanted to see me."* - **Error!100** said after knocking on his door. *"It's open."* -**Gaster** replied curtly, it looks like he's in his lab, and he can't open the door at the moment. **Error!100** hesitantly entered his cabin, and looked around for a moment before realizing that **Gaster** was in his lab. *"Why did you want me to come?"* - **Error!100** asked. *"I've already asked 300, 200, and none of them agreed..."* - says **Gaster**. *"For what?"* - **Error!100** asked. *"For a new project I'm working on."* - Gaster replied with passion on his face. *" Aha... well, what kind of project is this? "* **Error!100** asked. *" Fusion of a bug with a living entity like you! "* - **Gaster** replied. *"Could you elaborate?..."* - **Error!100** asked. *"Fusion is a chemical reaction that causes two certain bodies to fuse together, genetically, physically, mentally, and emotionally, at least in this case, fusion of you with this error would make you gain a little strength, your eye would repair itself , and you would feel WAY better."* - **Gaster** said excitedly. *"At least that's what my research indicates."* - **Gaster** added, then laughed lightly. *"If you say it will make me feel better... then I agree."* - **Error!100** boldly replied. *"Brilliant, see that machine over there?"* - **Gaster** said, moving closer to **Sans**, pointing his finger at a mysterious machine that looked like a capsule. **"Yes, I see."** - replied **Error!100**. *"Go in and just wait, is everything clear?"* - **Gaster** asked. *"Understood."* - **Error!100** replied and entered the mysterious capsule. **Gaster** put on his gas mask and started counting down, placing his hand on the lever. *" Three ... two ... one ... "* - Before he could finish, he already pulled the lever, the entire capsule suddenly filled with pink gas, nothing could be seen from the outside. **Gaster** was just watching the whole process mysteriously when suddenly he began to hear terrible screams coming from the machine. **Gaster** knew it would be painful but he didn't expect it to be this painful, he continued to watch the whole process on the monitor showing his vital signs, everything looked normal, until his screams became louder and louder and he started banging on the glass. His vital signs were starting to fade, but **Gaster** continued, he knew the fusion wasn't complete yet. After hearing this distinctive sound, **Gaster** immediately turned off the machine and the door quickly opened, releasing all the pink smoke into the lab. **Gaster** watched, waiting to see what would happen. The lights in the lab suddenly went out completely, it was so dark you could barely see through the mask, but what he saw was all too visible. Red, scarred eyes suddenly emerged from beneath the depths of pink smoke, and looked straight at him. **Gaster** still stood motionless, he thought it was a temporary side effect. ***"What... am I?..."*** - Most likely said by the creature sitting in the cabin. **Gaster** didn't understand the question, he thought everything went according to plan. ***"What... have you made me?..."*** - The voice of the creature speaking these words began to become more and more deformed. ***"What have you MADE ME?!"*** - This deformed voice coming from the machine sounded very loudly, **Gaster** could see how the creature was starting to slightly get up from its knees, feeling slightly anxious at the same time. **Gaster** remained silent. The creature laughed softly in its severely deformed voice, then spoke. - ***"You created something... that you don't know if you can control... right? "***. **Gaster** remained silent. ***"What have you... What have you done... with my life?..."*** - He said in a deformed voice... **Error!100**. *"My eyes hurt..."* - added **Error!100** in a deformed voice. **Gaster** began to feel really anxious, he started to pull away slightly, and his face no longer looked as confident as it had been at first. ***" 707 ... "*** - said **Error!100**. *"What?..."* - **Gaster** asked. **Error!100** stood up, and part of his body was visible, especially his face, and that deformed psychopath's smile. *"The fusion worked..."* **Gaster** said under his breath. **Gaster** looked around, a moment of inattention, and the new entity was no longer visible. **Gaster** nervously looked around the labolatirum in the dark, but saw no one. **Gaster** only heard this deformed, silent laugh coming from somewhere in the depths of his head, and then he fell to the ground, his face terrified. The lights came on, and you could hear the unmistakable hum of the electric lamps above his head. **Gaster** took a deep breath, then took off his mask and sat on the floor in silence for a while, trying to understand what had just happened. **Gaster** got up after a while and walked to his desk without saying a word, took out a piece of paper and wrote the number *"707"* on it, then left the lab and decided to get some sleep.
