Sans vs Gojo
20XX
A group of what looked like cursed spirits was sighted on Mount Ebott. They have a young child in their capture.
Dispatched Sataru Gojo.
…
Gojo arrived near the location quickly. He was in a forest where he had the perfect view of what he assumed was the cursed spirits, although the energy they were emitting was different from what he was used to.
He sighed and ignored that for now; it must be the technique that makes it harder to sense normal curse energy from them.
Gojo was about to shoot out a blue. He was first going to take the child the spirits had in captivity to safety, then deal with the rest of them. But then, he suddenly felt a presence behind him...
“Human, turn around and shake my hand.” A certain skeleton in a blue jacket said. Gojo, on instinct, swung behind, but Sans dodged back. “Or I guess not.”
Gojo smirked, turned around, and saw Sans in all his glory. Sans taunted, “You must be another one of the spirits, almost didn’t notice you, your output is weak as hell.”
“I never bothered with being strong. But I still have to protect my friends from you.” Sans told Gojo.
“Friends, huh? Well, you're welcome to try.” Gojo said, while taking off his blindfold for a second to reveal his glowing eye.
“I guess you're willing to have a bad time?” Sans said as one of his eyes started to flash yellow and blue.
FIGHT!
Sans summoned a bunch of bones from behind him. He sent them flying at Gojo, but that first volley never reached, with an infinite gap between them.
Gojo waved away the bones, “Gonna have to try better than that,” he rushed towards Sans, going for a kick, but Sans bent back and dodged.
Alright then, if you say so,” Sans said before having another bone appear, and it swung towards Gojo. Gojo didn’t bother to dodge it, thinking infinity would make it a non-issue, but then he felt it lightly tap his head. It was weak; it barely even hurt. But it went completely through infinity and touched him.
Gojo immediately grabbed the bone and broke it in his hands. He shot out a lapse blue from his fingertips, and had it start dragging Sans towards him, but Sans disappeared. Gojo felt something coming up from the ground and leaped into the air before bones came jutting out of the ground. Gojo was floating midair, and bones came flying out of the forest. Gojo was dodging them mid-air, using lapse blue to drag the bones into one place and reversal red to push them away. All in the meanwhile, he was theorizing how this seemingly weak curse spirit could even manage to bypass infinity.
“His technique might be able to have his attacks directly attack the soul.” Gojo speculated. That theory had more evidence added to it when he felt his very soul be grabbed and pulled back down to the forest suddenly.
He nearly fell into a pile of bones back-first, with Sans standing beside them, but Gojo teleported to catch Sans off guard, only for Sans to teleport away again and then turn Gojo’s soul blue and toss him into a tree.
“I thought you needed to put a bit of backbone into this!” Sans joked.
Gojo smirked again, “Your jokes are pretty hollow, you know!” He then let off another Lapse blue, this time far larger and more destructive. It behaved like a vortex sucking up trees and branches, and having Sans try to avoid it.
Gojo thought to himself, “ he seems incredibly keen on not getting touched even once, like one hit can put him down for good.”
Branches came flying toward Sans, but they were blocked by him summoning bones, then he sent those bones flying at Gojo. Gojo commented, "Being quite the annoyance, you know? making me take time from students."
"I'm someone who likes wasting time as much as I can," Sans responded
Gojo dodged the bones like they were nothing came at Sans once more; more bones came out of the ground to protect Sans. But these bones were blue. Gojo was still expecting to break through them with ease, but phased through while his soul took damage, and Sans dodged once more. Gojo now started to notice that Sans's attacks seemed to be poisoning him in some strange way.
“I can tell you gained a lot of LOVE in your life. How does your sins crawling down on your back feel?” Sans asked, his eyes completely hollow for a moment.
Gojo stopped playing for a moment. Faster than ever. He appeared in front of the skeleton and went for a hit. Sans dodged, but Gojo predicted it and landed a black flash on Sans. At least, that’s what it looked like.
Gojo saw what looked like blood coming out of Sans, staining his shirt… Only for a broken ketchup bottle to suddenly fall out of Sans’ shirt.
“Oh, come on, that was my last one,” Sans said while zipping up his jacket. The ketchup bottle took the hit of the black flash and protected Sans.
Gojo said, "You got lucky there, but that's about to run out."
"Nah, I doubt it," Sans responded.
Gojo raised his fingers to the front of his face. And whispered. “Domain expansion, Infinite Void.”
A domain was made around the two fighters. Ever stretching space could be seen all around them, infinite information meant to overload the mind of whoever Gojo trapped inside of it. But there was zero mind to process it.
“Um, is something supposed to happen around here?” Sans asked, sort of confused.
“Your… Your body is supposed to stop while your mind is taking in information.” Gojo explained calmly, but on the inside, he was going a tad insane. Trying to figure out what Sans even is at this point. He is unlike any curse spirit he has fought… Is he even a curse in the first place?
“Oh, sorry, bud, nothing’s inside here, I’m quite the numb skull.” Sans chuckled while doing another awful pun.
He then made something materialize within infinite void, a Gaster Blaster.
It shot directly at Gojo’s soul. Gojo dodged, and it hit the wall of the barrier instead. Sans summoned more Gaster Blasters, and they shot at the walls of the barrier, overwhelming it, until Infinite Void shattered.
More bones came flying at Gojo, but by this point, he was getting a far better feel for Sans' attacks, even the versions where the bones were blue.
Sans turned his soul blue and fell to the ground, but Gojo saw something big: Sans was (somehow) sweating, and he was getting tired.
Gojo teleported right at once more to Sans, only for the skeleton to summon another Gaster Blaster, this one trying to entrap Gojo in his massive jaws, only for Gojo to pry them back open and break out.
Gojo said, “You are delaying the inevitable.”
Sans simply replied, “I think I’m used to that.” He did a deep sigh and had his blaster charge up a blast, meanwhile, Gojo raised his fingers, combing and fusing the elements, the techniques of red and blue, creating…
Hollow Purple!
The beam from Gaster Blaster clashed with the purple; the blaster started to lose quickly, though. Sans summoned more of them in a desperate bid to push back purple. It was working, but Sans was pushing too hard. Sans focus slipped for a moment, and the Gaster blasters, helping out, were destroyed.
Sans looked on as the purple grew in size, destroying everything in its range. The main Blaster he was using held on for longer, but that was consumed by the whirling purple.
Sans quickly moved out of the expanding hollow purple, but Gojo gave chase, and by this point, Sans’ energy had run completely dry. Gojo caught up and grabbed Sans by the head, and then slammed him down to the ground. Finally landing the one hit he needed.
Gojo got up and backed away from Sans. he looked at him, beaten up on the ground, minutes away from being fully “exorcised,” he asked. “Are you even a curse spirit to begin with?”
Sans slowly shrugged in response. “I don’t even know what that is. I’m just a monster.”
Gojo groaned in frustration. After the purple dissipated, he took a look down at where the kid and other curse spir- I mean, monsters were. He noticed that the kid had zero fear; they were genuinely bonding and enjoying their time with the beings he perceived as evil. Well, once did anyway.
“I… see “ was all Gojo said.
Sans said, incredibly weakly, “I don't care if I'm going, but let them have a future. That's all I'm asking.” Those were the last words Sans uttered before being reduced to dust.
After a long time of standing there in the demolished forest in the mountains, Gojo simply left. Now that he knew there were no cursed spirits for him to deal with.
Meanwhile, over on Mount Ebott, where the monsters were coming out, finally free from the underground, the human Frisk. Looked on over to where the fight occurred. Papyrus walked by for a moment, and he asked, “Hey, Human! Did you know where my lazy bones brother went off to? Been trying to look for him."
Frisk lied and shook their head. Papyrus went off to keep searching. Meanwhile, they were now looking at a save point. Thinking over what they should do now.
KO!
Ok, for the explanation of the winner, it's mostly clear cut, as shown in the fight, Sans has ways of bypassing Gojo's infinity. Most solid being turning his soul blue and being able to toss him around, and some arguments can be made that Sans can bypass infinity with all his attacks, not just blue soul, thanks to directly targeting the soul like in-game, but those are far more dubious, even if I did follow that logic in the script to make it more interesting. Anyways, Sans should also be immune to the effects of Infinite Void, by virtue of not having a brain. Beyond that... Gojo just kind of wins. His stats are far stronger, both of their speed scalings are a bit strange, but Gojo's is more reliable, and biggest of all, Gojo can really just wait out Sans until he eventually gets tired and Gojo can land the one hit he needs to end him, and Sans will always get tired out way before Gojo can run out of curse energy, thanks to Six Eyes.
The Winner is Satoru Gojo!
