Underswap: Maniacal Slaughter: Death Wish Sans

Underswap: Maniacal Slaughter: Death Wish Sans is an AU based on a combination of Insanitytale and Underswap: Distrust, created by JesterBones4150.
== Appearance ==
He looks like Underswap Sans, but wearing a very tattered version of Underswap Papyrus' hoodie with a rip down the middle making it resemble a jacket. He sometimes wears the hood up. His outfit is very tattered and covered in blood and dust. His head is very cracked. His eyes have a similar color scheme to the blue, green, and yellow of Dustbelief Papyrus, in the shape of Insanity Sans' eyes. He carries a pointed bone staff with his brother's pensive upper skull on the middle, stabbed through a hole in the top.
==Backstory==
It was a particularly cold day. Even for Snowdin, it was almost a blizzard. The Magnificent Sans was heading to the ruins door, trying to look for his brother Papyrus, who went missing that morning. Sans eventually made it to the ruins door, and heard a commotion from behind, what sounded like a fight... after a bit, all was silent, and the doors to the ruins swung open, dust pouring out, and Papyrus was just... standing there, twitching a bit. Something was wrong, from the dust on his clothes, to his insane expression. Sans tried to approach Papyrus and ask what was wrong, he wanted to help Papyrus... but instead, what Sans got was a swing to the skull from a sharp bone. Papyrus lashed out at Sans without even saying a word, and Sans had to fend him off the best he could, desperately pleading for Papyrus to just stop and tell him what was going on. Papyrus's fighting was vicious, while he still used his magic, he was much more ruthless when it came to physical combat as well, something seemed to be leaking from his mouth as well. While Sans was able to hold Papyrus off, he was taking serious damage, his skull was becoming cracked all over, and his clothes were getting tattered from near-misses from Papyrus's attacks. When Sans was at his weakest, Papyrus simply laughed, charging up a giant blaster and aiming it right at Sans... Sans tried to simply pin Papyrus down to stop the fighting with some bones, but he missed... but in an unexpected way. The bones caused Papyrus's attack be interrupted and pin him down to the ground after knocking him down, except... all the bones impaled Papyrus himself, bringing him to just one hp. Sans was deeply apologetic, sincerely sorry for Papyrus, he slowly approached Papyrus, promising that he could take him to Undyne to get him healed... but in an unexpected move, Papyrus pulled out one of the bones that impaled him, and stabbed himself with it again, finishing the job. After Papyrus offed himself, oddly, his body didn't immediately dust, leaving Sans to mourn the death of his brother... although strange smog was coming out of Papyrus's skull, and unknown to Sans, due to the bones he accidentally hit Papyrus with, he got a bit of LV from Papyrus's death. The extra LV combined with accidentally inhaling the smog was already starting to have it's effect on Sans's mind, he could swear he could still hear Papyrus... Then, Sans experienced a strange hallucination. Papyrus's skull stopped emitting smog, and grinned, looking up at Sans, to Sans Papyrus seemed to be alive still, when he really wasn't. Papyrus told Sans to take him along for the ride, to not leave him here. Sans asked how he could bring Papyrus with, and the response he got in the hallucination was to tear Papyrus's head off and take it home. Reluctantly, Sans did what "Papyrus" asked, tearing his skull off his body. Sans doing that caused the body to dust, but the head didn't dust oddly. As Sans headed back into town, unknown to the skeleton, a human had just fallen into the underground, having to traverse the now empty ruins, and experience the madness unfold... 
When Sans got back in town, a panic immediately began after a few people saw how Sans was holding Papyrus's skull. Sans was worried that he was a criminal now for what he did, he tried to explain himself to the crowd of panicking Snowdin residents that weren't able to listen, one of them even headed into Waterfall to get Captain Alphys to deal with what appeared to be a rogue and dangerous Sans. After a while of panic in the town and Sans freaking out, Alphys got to Snowdin Town, and saw Sans... she couldn't believe what she was seeing, but if the people were scared of him, it was obvious that he was going to be a threat. Alphys struck at Sans, causing more damage than he took already, the blade of her axe giving one of Sans's eyes a crack scar. Sans once again defended himself, but he swore that as the battle raged on, Papyrus was whispering things into his ear, telling Sans to just kill Alphys. Sans tried to not give in to his hallucinations, but eventually, he had to, starting to take the offensive in the fight, managing to fight back against Alphys. Sans used his magic to create a long sharp bone, which he used to impale Alphys through the chest, getting blood on it before pulling it back out. Alphys was shocked that she was struck down so soon... something seemed to be different about Sans, as Alphys slowly melted, Sans's expression changed into a wicked grin as he sped things up by impaling Alphys over and over until she was no more... Sans turned to the panic that was still happening in the town, and Papyrus told him to go wild, so Sans did, killing off everyone one by one, gaining more and more LV as he did... Sans was officially broken due to his hallucinations, listening to the voice of his deceased brother's head for further instructions.
After the frenzy in Snowdin Town, Sans had much more LV, everyone in town either being dead, or having fled. The voice of Papyrus instructed him to go get his hoodie next, as Papyrus thought Sans would get cold without something to wear over his battle body. Sans put Papyrus's head on the large bone he used to kill Alphys before heading back into the forest. When Sans got back to the ruins door once more, he picked up Papyrus's tattered hoodie, that was much more like a jacket, being torn down the middle so that it was open. The hoodie fit on Sans, but Sans also encountered something else while retrieving his brother's jacket...
