I got bored and wrote 2719 words in one sitting. It's fucked up. It's a dumb idea. Take it. Oh and its based in underfell

Just because the humans were no longer ruling the surface didn't mean their scientific studies should be abandoned. That was his argument for continuing their studies in biology. He was the royal scientist after all, and after figuring out everything there was to know about soul power, well... he needed a new topic to research. So, finding all of the human notes and literature he could on the subject of evolution, he set to work figuring out how monsters fit into the earth's history. He knew that monsters could indeed interbreed with humans, as there were many reports of monsters' intercourse with their human slaves resulting in offspring. Those offspring, however, could not produce children of their own, so the idea that humans and monsters were the same species was out of the question. He did want to figure out where Monsters fit into the whole genetics thing. Obviously it would make sense to assume that monsters were made of something entirely different than the rest of the earth's inhabitants, but they could produce offspring, which meant they had genes and their gametes worked together and were similar enough to make zygotes, meaning they had to have cells. He'd decided to work with his own cells and DNA, and to branch off to other monster types afterwards. He purchased a female human to use for comparison between his cells and hers. He treated her well enough, after all she was sentient and he wasn't as horrible as most, and for this she seemed grateful. He kept her in a cell, though it wasn't an uncomfortable one. He'd painted it what she claimed was her favorite color, green, and it had a soft bed, a walk-in closet, and a connected bathroom and sink. He brought her meals daily and they would talk. He took a liking to her, and they became friends. He connected a small garden to her cell, and made sure she had books to read and things to keep herself entertained.

He did, however, refuse to let her leave the cell. She didn't like his procedures, the testing on her and taking samples of her different cell tissues, but he couldn't help that. He could not let their friendship take away from his job. He continued with the experiment further. He found that he did indeed have cells, and they were quite comparable to the human's. The flesh he was able to summon on his body shared many similarities with her flesh. It did indeed have cells. Though there did seem to be an extra organelle in each cell, he simply noted it for later investigating, theorizing that it had something to do with a monster's magic.

He felt great regret when the research became demanding of something new. He needed to look at a zygote. Not a simple human or monster zygote. He needed a hybrid. He had a female human, and he had himself. And though there were other ways to impregnate the human, they required extra procedures that he just didn't have the time or patience for.

He didn't really enjoy it. It was pleasurable, as sex normally would be, but the human struggled. She made it very hard, and the guilt hit the scientist hard. He apologized multiple times after removing the newly-formed zygote from her body, (a very tedious and difficult task,) but she wouldn't talk to him anymore. She cried when he told her he would have to do it again. Science required multiple tests. He studied the zygotes, messed with their composition a bit, and compared them to human zygotes he'd managed to get his hands on. He didn't have any monster zygotes to compare it to, though.

He'd tried to get some, but Asgore didn't like the idea of experimenting on what had the potential to be a monster child. Gaster had scoffed at that. Murder, burglary, and rape in the streets was acceptable, but noooo. Not experimenting on a child. He took matters into his own hands. He looked into the human's research on cloning. After a few failed attempts, he succeeded in making a small skeleton, managing to give it some different features with DNA he was allowed to have from another skeleton. The child was never a zygote, however, but... the scientist had plans. Once the child was stable, it was moved to a cell. This one wasn't like the human's cell, it wasn't nice, or warm, and it didn't have a bed. A cold, cement room was its living space, with nothing but a thin blanket inside. He fed it, but ignored it otherwise. He still talked to the human, apologized, and asked what would make her feel better. After a year or two, she forgave him. She allowed him to continue getting the zygotes from her, but only once a month. He held to this arrangement: he didn't want to lose his friend's trust again.

The skeleton in the other cell grew quickly. It also quickly became afraid of the doctor, who always seemed angry at something when he came his way. Less feelings were available to the doctor, now. The skeleton, who he'd come to call 'subject one', had half of his soul in it. It'd been required to bring it to life.

He brought his anger and frustration with the world and its demanding nature with him on his short visits to the small skeleton. The results were apparent on the small, naked body. The child quivered in the back corner of the cell when he came to bring its food. When he was angry, he would approach it, kick it, punch it, anything to get his negativity out. Though he regretted it afterwards, he acknowledged that it was the only reason he didn't lose his patience with the human and their agreement. He needed more to work with than he was getting. It was frustrating.

Eventually, after eleven years or so, he decided that subject one was ready. He brought it out of the cell. It trembled in his hold, terrified. He brought it to a table in his main lab. The small, scarred creature shivered and stared at him, its eyes wide and afraid.

After the intercourse, it trembled in the corner of the lab, sobbing silently. It'd never made a sound, and had yet to.

Gaster growled and glared at it. The attempt had failed, no zygote was created. He tried a few more times that day. With each attempt, he got angrier. It did work late that night. He removed it and threw the poor subject back into its cell. It shuddered violently and curled up upon the impact with the floor, nursing a broken humerus and multiple other cracked and bruised bones. He hadn't bothered to clean it, either.

The next morning, it wouldn't even move to eat.

Gaster didn't really care. He ignored it and talked to the human for most of the day, taking a break.

A few years passed. The skeleton didn't grow any more. Gaster made it help around the lab. He had it wear a collar so it couldn't attack him, and took his anger out on it whenever he felt the need to.

The skeleton seemed to have found its voice, and Gaster didn't like it. It did not talk, and mostly stayed quiet, but its crying was bothersome. He would beat it when it got too loud.

He knew it could talk. It would whisper to itself in its cell, the sounds always ending in soft sobbing. Their 'sessions' became more frequent. Gaster enjoyed them. After all, it belonged to him, it was his slave. He would do what he wished with it. When he managed to impregnate it, he would take the zygotes. He messed with them and once decided to put it back into the skeleton. The cell multiplied, and soon there was child floating in subject one's red, translucent body. Gaster stopped beating it for the months in which it was pregnant. When the time came for it to give birth, he helped remove the child. He smirked at its appearance. He'd taken things out of it, and put a few in. He hadn't looked at it before. The small skeleton didn't have eye sockets. Its skull was smooth and rounded over like the rest of the skull where the sockets should have been. It only had three ribs on each side, and instead of a fibula and tibia, it had a deformed hand.

He left it with subject one in its cell. The small skeleton was still weak from the birth. The abomination of an infant searched blindly for him. It dragged itself and bumped into it. It scrambled back away from it, staring in terror.

Something strange happened over the next few days though. Subject 1 took it in. It held it close like a teddy bear at night, and the thing cuddled back. One day, about a year into the abomination's life, when subject 1 was around fifteen, it stood at the door when Gaster came to deliver the food.

He looked at it, bored, but slightly intrigued. It held up the abomination.

"Fix." Its voice was small and unsure. It sounded far too young for its age.

Gaster scoffed. "I can't fix it. It's broken.

It trembled, its bones cracking together a bit.
"I-i... fix?"

"You'll fix it? Ha. what can you do?"

"...try."

"You know what, fine. I want to see this."

He grabbed its arm and wrenched it from the room. He dragged it to the lab and puszhed it in front of him.

"Go ahead. Fix it."

It looked at him for a moment. Then it walked into the large room. It set the toddler gently on a counter and began gathering things from around the room.

Gaster was surprised. The thing was quite intelligent, it must have learned from watching him all those years.

It whispered what must have been words of comfort to the small toddler, and injected something the scientist recognized as an anesthetic into its arm. It went limp. The teenager took a pencil and shakily drew two ovals on its face, where its eye sockets should have been. It whispered a word to the abomination, and took a small cutting tool. It was sharp and spun. Subject 1 managed to steadily cut the lines he'd traced, until the abomination of a skeleton had eye sockets. He took something like sandpaper and smoothed them out. It then took more than three hours.. removing its own ribs. It somehow managed to connect them to the abomination without them dusting, until it at least looked recognizeable. It somehow made them look the right size as well. It then separated the deformed hand from its leg, and took two more parts of its own ribs to serve as a tibia and fibula. Somehow, this worked. It took the hand and chipped part of its own patella off to serve as a heel, which was connected to the leg.

The resulting skeleton looked.. not normal, but not disgusting.

Subject 1 picked up the small child and limped to him. Its chipped knee seemed to hurt to walk on. It looked up at him, beginning to tremble again.

"y-y.... you no touch..."

"Hah. You expect me to listen to you? You both belong to me.

"No. Not yours. Mine. My brother."

"Brother, huh? But it's your offspring. Are you denying the fact that you're just my worthless whore?"

It flinched and looked down.

"Don't worry though. I don't want to touch that abomination."

He led it back to its cell and shoved it in. It wrapped the smaller child in the blanket and hugged it close.

Another few years past. Gaster continued using Sans and the human, though the human was becoming old. She spent more time out in the garden, just sitting. She hadn't failed to notice the scientist's fast decreasing kindness. One day, he left the door open after bringing her her dinner. He was tired and wanted to get home. His half-hearted shove did not close the door properly. She noticed as she walked to her bed to turn in. Her breath caught in her throat and she stepped out.

She began to walk down the hallway, towards subject 1's cell. It heard and scrambled away from the door. She heard this.

"Hello?"

Subject 1 did not know that voice. It did not respond.

The human slave opened the door. It was not locked on the outside. Subject 1 stared at her.

She gasped a little bit. "Who are you?"

It clearly did not trust her.

"Who you?" Its voabulary was still not good.

"I'm..
Well... I haven't got a name."

"You... human slave?" It tilted its head.

"Don't say that word. I don't like it."

"Scientist... says about you. Sometimes."

The smaller skeleton in its arms curled up a bit at the word 'scientist'.

"Oh. Why are you here?"

"Experiment. Scientist made me. H-he made me make...
Called it... zie-goats? Then took them. Hurt."

His meaning got across to her well enough. "Oh, you poor thing! How long have you been here?"

"Here?
All time. Doctor say... years... seventeen."

"S-seventeen?"

"Yes."

"Who is that?"

"Brother. Doctor... put zie-goat back. B-broke it. Came out of me."

"O-oh you poor things..."

"Why you say 'poor things?
What you mean?"

"I mean... you don't deserve that. That's horrible."

"...is my life.."

"Well... come with me. I want to take you away from here."

"Safe?"

"I... I'll try to take you somewhere safe..."

"Somewhere safe.." It stood. It followed her out of the lab.

"He led me in here many, many years ago. I will try to help find the way out." They soon exited the royal scientist's lab area and came to the lesser labs. They were close to some double doors marked exit when footsteps echoed up the hall they were in. The human pulled subject 1 and ducked into a room.

The footsteps came closer, but instead of walking by, the room door was open. The human pulled then through another door into a small lit room. An apple stood in the center. There was a window in and a window out to the side , then another window into a room identical to theirs.

Two monsters entered.

"Ready to test it?" One asked.

The second grinned. "Yes. If it works, we'll have created the newest means of transportation.. teleportation. Imagine it. We might even get a raise."

"Well. Put your goggles on. I'm starting it up."

Movement. Then noise. The lights became unbearably bright. Subject 1 trembled.

Then, there was a loud noise and everything disappeared.

- - -

1-s came to to feel a fluffy white substance around it. It was cold against its naked bones. It shivered and slowly stood.

It noticed what it was missing and whirled around. Its voice croaked weakly. "B-brother?"

It could barely hear itself over the loud ringing filling its ears.

A soft crying could be barely made out over the deafening ringing. It stumbled towards it. There was its brother.

It picked him up and looked around. A bit of color caught its eye and it stumbled towards it. It soon collapsed, cold an exhausted.

It woke to an unfamiliar face.

"Kiddo, wake up."

It flinched and scooted away. It looked around wildly. Color. Color surrounded it, more than it'd ever seen before.

"Hey, calm down, I'm not gonna hurt ya."

"B-brother-
Where is b-brother-"

Its broken English came out fast.

"He's okay, he's sleeping in the armchair there. "

Sure enough, there he was.

"Who you be?"

"Me? I'm Papyrus. Papyrus the skeleton. And uh.. if I may ask, what are you called?"

"Subject 1."

"What? That's not a name."

"What-
What on me?" It pulled at the grey T-shirt covering its ribs. It felt weird.

"Those... those are clothes. Have you never worn them?"

"No?"

"Oh... um.. where do you come from?"

"Lab. Scientist."

"Oh my... how old are you?"

"I exist... 17 years."

"Woah, really...?"

A small sound came from the armchair. The toddler was awake and looking at them. "Bwaahbah?"

Subject 1 limped to him quickly, brushing past Papyrus. "I here, b-brother..."

There are probably a shit ton of typos

Honestly I don't care I'm so done rn

I might write more. I dunno

Well this just looks shitty
Anyways
