#he's got that dawg in him aka a parasite

[fineapplequeen]

Mweheheh I just cooked up a sans oc like my life depended on it, he's absolutely fabulous (im bias) and traumatized (im cruel)

It's a bit of a read, 2,000 words just his backstory, but here he is :) Raw and his rave parasite

This follows a timeline where Sans is being guided by Gaster to become the next head scientist, being created by Gaster in the lab and told this was his purpose in life, to continue Gaster's legacy and work towards building a harvesting machine in the labs that could potentially harness the entire undergrounds magic and break the barrier.

At the time, Sans followed along, not knowing much about the underground, and quite shy when it came to those who visited the lab. The King would often visit, kinder and softer toned than Gaster, the King spoke of two children he had and offered Gaster to set up playdates with all the kids. Gaster found it irking that the King was meddling with his projects affairs but he allowed it, only in their down time for a couple hours every week.

Sans, a child at the time, was confused when the King guided them to the castle the first time, with Gaster following along. Life for Sans was work. All he knew was the walls of the lab and the cameras showing what was outside. It never occurred to him there was anything beyond the camera points- having thought they were each separate rooms enclosed like he was.

The ride up to the castle from the elevator was dull, Sans completely unsure of why they were doing a play date in the first place. Sans was technically 'in stripes' at the time, but he wasn't made to have friends.

Things began to change when he met the two children called Asriel and Chara.

At first they were simply annoying, and Sans had a hard time connecting to the two who were pranksters, running around and conjoined at the hip nearly as they masterfully planned their mischief- dragging Sans along for the ride.

He didn't get it. Not at first anyways. The jokes were always on nearby monsters, harmless, just to cause a silly reaction for them to laugh at. Sans stood by their side, feeling more like a babysitter than an accomplice. That changed the day the two told Sans of their new plan- to prank Gaster. It made him nervous, Gaster was a serious monster. The two children claimed he would find it funny though- and so Sans agreed, a small bubbling in his chest when they successfully pranked Gaster and for the first time- Sans laughed.

It was one of the more sillier pranks they've done and Sans helped with the height issue, using his magic to stick saran wrap to the door at Gaster's height. Seeing him walk through it and make such a face made Sans double over, the best part, Gaster didn't get mad like he thought he would. The King had come to check why all the children were laughing, chuckling when Gaster explained what had happened and they both had a laugh. From then on though, Sans never got over that high, finding himself doing little harmless pranks in the lab too- as long as it didn't interfere with work. Gaster seemed to tolerate it, for a little while, up until Sans took it into their work life too.

That's when Gaster had enough. For the first time since Sans was created, Sans got in trouble, grounded to his room for a couple of weeks, not able to work or play with his new found friends. It could have been worse- but for Sans, this was the worst. Seeing Gaster so disappointed, those enraged eyelights staring down at him, calling Sans outrageous and childish- but to Sans's defense, he was a child. He just learned how to have a smidge of fun for the first time but Gaster forbade any more pranks from then on, and lessened Sans's visits with his friends in order to work more.

Sans was told to study more, tasked with furthering himself for science while Gaster tested him at every turn.

It was just another week, a couple days after visiting Asriel and Chara that things took a sharp turn and Sans learned the meaning of loss. Both royal children died overnight.

Gaster and him both came to the funeral for the children, monsters shuffling to the castle in hoards to mourn the loss of two innocent lives. It was then, walking past the house they used to play in, down the halls of the castle, shuffling through golden doors to a longer hallway with stained glass windows, basking everyone in warm glows from Hotland, Sans felt something sneak inside of him.

It curled and nestled, warmer than anything he had ever felt, and it filled his thoughts, whispering to him, calling to him.

Judgment.

Judgment.

Judgment.

Gaster's grip on his shoulder tightened and Sans looked up, eyelights burning in gold and teal. Gaster looked down at him, and without a second thought, looked away, grip still as tight and face tense.

Sans looked forward, sockets large.

It was as if peering into the depths of Gaster's soul when they made eye contact, Sans had plummeted and emerged in milliseconds, and somehow knew everything about his creator in that time. Not everything, but his very status and what he was thinking. It was the same with any other monster he made eye contact with from there on out... and it scared him.

Things changed. Sans was given a gift, said the King. Passed down from the dead child Asriel, Sans was given the gift of Judgement... and he hated it.

Gaster was even tougher as the years passed. The King came by more often as The Queen had disappeared in her grief. Sans was taught everything by the two older monsters, from a Judge's job to being the next royal scientist.

It was overwhelming. It was soul shattering to most.

Sans was not most.

He grew up. Isolated, tired, sad. He stayed strong... and sometimes... sometimes, he left. He left the lab, wandering the quiet parts of the underground, watching the lives of those living and pulling pranks in the dark, watching the silly reactions of monsters, those never knowing that he was behind them. Sans grew stronger in those moments, and lonelier.

Gaster eventually found out. He always eventually figured things out when it came to Sans- it led to an explosive argument and for the first time in his life... Sans used his Judgment abilities on Gaster... and hurt him. Then. He ran away.

Sans ran. No goal in mind but to escape. He was fearful of the consequences despite now being an adult- Gaster was always able to make him feel as small and helpless as a child.

He ran where the light barely reached, where there were no cameras, a dark and damp place in waterfall where echo flowers didn't grow. There he sat, curled up small, trembling from using his Judge abilities- shaking from overpowering the royal scientist. He never knew it could be that easy to push back... and he didn't like how his soul felt afterwards.

Sans was too shaken up from the cold in his soul to feel the coiling around his leg, climbing up his arm- blinking slowly when it reached his neck and whispering to him.

Promises. Reassurances. Hope.

All he had to do was give in...

Sans blinked, his guard lowering. That's all it took.

A slippery being forced itself through his mouth as he tilted his head back, climbing through and assaulting his soul beneath his sternum- leaving sucker marks in its wake- but Sans' defensive rose.

Light poured through the area coming from all of his joints and through his skull- the creature that tried to take him over was melded to his soul, the tentacles coiling around it were unable to retract- as they were a part of it now... and the creature was stuck inside of Sans' skull.

A rave parasite, is what Sans found out it was called; when he woke up from the overuse of burning magic. It had charred him from the inside, his spine and ribs closest to his soul were cracked and blackened, and the creature was shaken up- able to feel what Sans was through their 'bond'. The creature gained emotions- more than it already had, and it gained morality, able to see bits of the past that Sans had lived, able to sense the emotions flowing through him. The creature apologized profusely and gave Sans the reasons why it did what it did, it needed a host and a soul to feed off of.

Neither was sure of what this meant for them...

Neither wanted to seek Gaster out to have him help with this... problem. So. The only logical thing the creature provided was for Sans to just leave. Find someone else who could help them seperate.

Sans was unsure about that until his soul began to buzz faintly- and a glowing rift opened next to them. It was a whole new world of possibilities... and a whole new experience of life itself as Sans opened the gigantic can of worms that was- the multiverse.

Life in the multiverse... was insane. Sans was smart though. He was not one to talk to strangers, unless being witty and laid back about how he went around gathering information. Except. Something was off. Monsters wouldn't look him in the eyes when he talked.

Eventually he figured it out when looking in a mirror. That was not his eye. He could still see out of both sockets- but that was not his eye- and his other... the other socket was dark but there was something... moving around in there...

It was the parasite.

Sans learned to live with it. He didn't like it but they would soon be separated so he pushed on... but the more he searched, he found the smartest in most multiverses to be Gaster- who he didn't want to interact with- nor did he want to interact with alternate versions of himself... he had managed to avoid them altogether.

The parasite found this amusing but didn't tell Sans why... and eventually Sans got tired of being called that name too. Every universe there it was again. Sans. The name Gaster gave him when he was made. Even in universes where Gaster wasn't present- Sans was. And they were smart. Smart enough to figure out they were being watched when the parasite and him risked willing to watch them for a bit to see if they were royal scientists or had any promises of being able to help their fused soul and tentacles... but they were dangerous too.

He no longer wanted the name of Sans, the longer his search continued. He didn't feel like he deserved the name, as silly as it was. He wasn't who he used to be... and he wasn't sure he could ever be that person again. So he came up with a new name for himself.

His name was Raw.

Raw was him and his parasite, the two bonded over the naming process in some dark corner of an alternate waterfall. Raw had begun to lose hope... a very vital thing that made up a monster- and the parasite noticed and offered a distraction.

Everyone needed outlets, everyone needed reasons to see through to the end, everyone needed fun and life experiences- and the parasite offered just the solution, making their soul feel giddy as it showed Raw how to look for a function called a rave.

They were loud. They were obnoxious. They were everything Gaster would have hated- and Raw had never felt more alive than when he went to his first rave- high on the symphony of happy, screaming souls and excitable bumpy music and flashing lights- bodies flailing around and loose, having fun, no one having a care in the world... Raw wished Chara and Asriel had a chance to do this- but they didn't. So he did in their stead. In the middle of searching for a way to seperate himself and the parasite- the two accidentally pushed themselves closer and bonded over their shared fun of these events.

Raw became a being filled with unsettling amounts of magic, fun, and hope. Is newfound joy- bringing that same excitement to new universes that had yet to experience the pure joy life could bring if you just let it. He and the parasite were inseparable, and they were both okay with this fact after a long while.
