A/N-
so first off, sweet mother of asgore thank you guys so much for all the favs, follows and reviews! it means the world to me! i'm putting this chapter out quickly as a thanks, and also because i had written the equivalent of three chapters for the first draft of the story, which ended up being like 6,000 words, so i split it up into the first three chapters. you guys also found out my not-so-secret that parts of this are steven universe inspired because, what can i say? i'm a sucker for the show.
i also got a question on the gender of both frisk and the fusion! yes, should frisk be, at the least, a teenager, their body would show signs of their biological gender, but I think that, since they're agender here, frisk would take the steps to hide it? like binding if they were female. and the fusion is gender neutral as well since frisk and sans are, technically speaking, of two different genders, so the fusion wouldn't be male or female.
also, it seems like you guys don't really like the fusion's name, and to be honest, i don't really either. i'll almost definitely change it, but i've got a couple ideas as to what. my friend suggested 'Saris', but i also like 'Frans' which was suggested by one of you guys. I'm not quite sure which one it'll be changed to, but it will definitely be changed before the next chapter!
and with that, apologies for the long Author's Note, thank you all so much, and lemme know what you guys think!
The next week was, perhaps, the most interesting week of both Frisk and Sans' lives.
After the whole episode that could only be described as "catastrophic", the two other fusions broke into their separate parts to aid the strange human/monster fusion to the best of their abilities. For Alphys, this involved many tests. Too many tests. Checking determination levels, of which were abnormally high for a human, but still stable, were the most common of tests, but there were others.
The ex-Royal Scientist ran tests to see just what the fusion was made of, magic, determination, flesh, etc. As it turned out... The process of scanning the hybrid overloaded the machines. So, in the end, they had no clue what the fusion was made of.
'We're made of LOVE,' Sans bitterly joked from inside the fusion. Nothing else needed to be said for both to understand each other. Sans' dust was on Frisk's hands, and Frisk's blood was on Sans' hands. They both knew it, they just never talked about it. And they didn't need to. They understood through the mental connection inside the fusion.
In all honesty, they were a little scared by the fact that they had no idea what they were made of, and the fusion was glad that all they had been eating was monster food. They didn't think they were ready to feel what the whole digestion thing felt like. Frisk knew of course, but Sans' unknowing seemed to overpower Frisk's memories.
In between all the testing, the challenge was getting Toriel to allow the fusion to skip school. High school was important, especially since Frisk was a senior, and Toriel wanted her child to get the best possible education. But... It's not like the fusion could go to Frisk's classes for them, since they just weren't Frisk, but Frisk could only skip school so many days.
"Child," Toriel began, knowing full well that the fusion hated being called a child, "this is a most... Unusual problem, yes... But your education is important! Well, Frisk's is." They hated the fact that Toriel was a teacher sometimes. Sometimes.
So that's how they wound up in Physics, completely astounding their teacher with the knowledge that the teacher himself hadn't even known. Wanting to test the fusion's knowledge, the teacher decided to let them take the final at their request (off the record, of course) even though they were only halfway through the year.
Unsurprisingly, they passed with a perfect score.
And in every other class, the fusion fell asleep, much to the dismay of all the teachers. Early mornings and Sans didn't mix well.
Not to mention the constant barrage of "Who are you"s that seemed to never end. Telling the ones asking that, yes, they were Frisk to an extent, no, they were not dying, and to their monster friends, no, Sans didn't absorb their soul, they accidentally fused, only seemed to raise more questions than answers, ones they weren't all that comfortable with answering.
After that, Toriel figured it would probably be a better idea if they were homeschooled. Although most of the time that was meant to be dedicated to the fusion's education ended up being hours of never-ending puns and knock-knock jokes, normally about fusion. Turns out the fusion's just as "humerus" as Sans.
And, the most difficult thing altogether was deciding who the fusion would live with. While Toriel had initially wanted them to live with her, since Frisk was her child, Papyrus insisted that they had to live with him, since, "WHO ELSE WOULD READ THE GREAT PAPYRUS HIS BEDTIME STORY?"
The fusion hated to decide, since Frisk's love for their adoptive mother, and Sans' love for his brother were on par, both being extremely high. Seeing the look on Papyrus' face when they suggested staying with Toriel broke their heart, and memories of Toriel's saddened face from the timelines where Frisk chose not to stay with Toriel flashed in their mind whenever they considered staying with Papyrus.
In the end, they decided to switch off each week. The first week would be spent with Papyrus, while every other week, they would stay with Toriel. Although this didn't stop Sans' secret worry for his brother every time they were over at Toriel's. Frisk thought it was adorable.
Unfortunately, the next person who wanted to help the fusion was Undyne, and idea of "helping" wasn't any better than Alphys', no. It was worse... In a sense.
Undyne wanted to test the fusion's strength, stamina, power. Undyne knew just how tough the human by themselves could be, but what she really wanted to see was just how Sans' laziness hindered the human'a abilities. Oh, did she have no idea.
Throwing spear after spear at the fusion, the former royal guardsman quickly grew frustrated at the futile attempts to even land a single hit. They, somehow, managed to dodge every every single hit, enraging the fish to no end.
"How the FUCK do you keep doing that? Is Sans asleep in there or something?!" the fish warrior panted in between breaths as she collapsed onto the grass.
"Nope," the fusion chuckled, "he's wide awake. Both of 'em. But I guess... You've never seen what the 'lazybones' can actually do, huh? Howzabout I show you?"
The fusion stood with their skeletal arm outstretched, offering to help the panting fish warrior up. Undyne, not wanting to be 'helped' by the laziest being in the whole world and a human child simultaneously, smacked their hand away and brought herself up, leaning against a tree for support.
"Fine. You wanna show me whatever wimpy magic tricks you can do? Let's go! Fuhuhuhuh! What're you gonna do, spare me to death? Sans has only got one HP! I bet he couldn't even summon a tiny little bone if his life depended on it! And! AND! The little punk's too nice to hurt even a fly!" teased a now-battle-ready Undyne, spear in hand and lowered into a fighting position.
She straightened and stiffened when she saw the deadly look that crossed their white face, their eye sockets entirely dark, a haunting smile across their features.
"We're not as weak as you think, Undyne," they had stated simply, as a red light burst to life in their right eye socket, which surprised the fish entirely. The fusion had never referred to themselves as "we", always "I". Whenever they talked about Frisk and Sans, they talked about them like two completely different people, unless one of them was in control.
"So, tell me Undyne," their voice was eerily calm as they stretched their bony hand in front of them, summoning a blaster overhead, "do you wanna give up now, or do you wanna be in for a bad time?"
"Rrgh! You think I'm afraid of you? Hah! Let's go!"
The fusion let out a deep chuckle, closing their eye sockets.
"Let's go? Alright. Fair fight. Just one on two."
They opened their eye sockets, now alight with blue and red flames.
Raising their human hand, a wall of bones was summoned, flanking the fish on all sides, thus preventing her from advancing, while causing her to growl in frustration. She wasted no time in summoned a large spear, attempting to break the bones, but to no avail.
Busy trying to escape her prison, Undyne failed to notice the blaster that was summoned earlier had not yet dissipated, and was still hovering overhead, charging a blast. When the fish finally noticed, it was too late, and she was thrown harshly against the back of her prison of bones from the hit, breaking through it and crashing into a tree.
The fusion slowly advanced towards the ex-guardsman, keeping their steady, chilling gaze on her.
With a soft 'ping', gravity shifted, and Undyne saw her very soul, which was normally a vibrant green, turn blue. The fusion's left eye was now a strobe of harsh blue and yellow light, as the fish was picked up and slammed against the ground. The process repeated for a minute or two, but it was enough to slowly but surely dwindle Undyne's health down. For some reason, the attacks had lingering effects on her HP, slowly bringing it down even when it was her turn.
The fusion readied three more blasters, all talking deadly aim at the fish warrior. She was too weak to move at this point, unable to even move her arm to summon a spear. She growled, baring her teeth, but clenching her eyes shut to brace for the impact.
The loud whirr of blasters charging warned her of her inevitable fate.
That never came.
Looking up, she saw a familiar red scarf donned by a lanky skeleton, and she let out a small chuckle in relief. Never did she think she would be so grateful to see the guy. He was clearly scolding the fusion, that she could tell by his frantic movements, but her pounding headache made it impossible to tell what they were saying. Gods above did it hurt so damn much. They really did a number on her, and gods did she regret literally asking for it, because now her splitting headache made it nearly impossible to hear, and white spots were starting to appear in her vision. All she could see was that, once Papyrus' lecture began, the fusion's posture completely changed. Once cold and merciless, they had slumped down, looking more confused and mortified.
"YOU WERE DOING A VIOLENCE, BROTHER-AND-HUMAN! WHY WERE YOU DOING A VIOLENCE?" Papyrus asked. He didn't understand. Sans had never fought anyone, and Frisk was so merciful.
"P-pap... I-I..." they trailed off. What had they been doing? They stared at their hands for a second, and then at the three blaster hovering overhead. Had they summoned those?
"H-hey, thanks for saving me and all, but I'm still kinda collapsed here on the ground and I think this punk broke something. If you'd just help me out here-"
"Sorry, Undyne. Don't know what came over me. Guess you're a real battered fish now, huh? Well... On a scale of one to ten, how're you feeling? One being the worst, ten being the bass-t" they grinned widely, hoping to change the subject.
"SAANS-"
"I'm well enough to know what's a stupid pun of yours," she growled, her headache dying down, but still wincing every time Papyrus spoke.
"That's-"
"NO!"
"Fintastic news."
"SANS YOU ARE CORRUPTING THE HUMAN EVERY MOMENT YOU STAY FUSED!"
"Sorry, Pap. Didn't mean to anger you so much. Be careful, you might blow a fu-"
"YOU ARE NOT GOING TO FINISH THAT. WE ARE GOING TO ALL GO INSIDE, AND COOK SOME AMAZING FRIENDSHIP SPAGHETTI COOKED BY YOURS TRULY, THE GREAT PAPYRUS. AND THEN YOU ARE GOING TO APOLOGIZE TO UNDYNE AND WE ARE ALL GOING TO BE FRIENDS."
Gods, were they grateful for Papyrus. What would they have done to Undyne had he not stopped them...? The thought sent chills down their spine as the phantom feeling of increasing LOVE chilled them down to their core.
