This is an experimental story... on the other hand, everything is that I make as of now. The Name says everything, I suggest you should read it for more details. Loosely based on this: https://www.youtube.com/watch?v=9DTemq7TeNE The first part is a bit boring, but it gets better after that, promise! I hope you enjoy!

This is what would happen if Sans's prediction in Undertale Love Story was correct and one of the humans did, in fact, do a genocide run. let's find out!

A SEQUEL TO Undercats!!! MAJOR SPOILERS FOR THE GENOCIDE ROUTE It's been 5 years since Frisk freed everyone from the Underground. She and Sans had become a couple and were living with Papyrus on the Surface. But Sans begins to have insomnia and Frisk is tormented by the evil Chara. Until it all comes down to a RESET. Frisk must unsheathe her claws and throw away her pacifist nature in order to stop Chara from killing everyone, including Sans. Will she succeed?

It was just a normal Saturday. (Y/N) was playing Undertale for the millionth time. She was obsessed. (Y/N) had played all of the routes. True Pacifist, No Mercy/Genocide, Neutral. She experimented with killing certain characters doing different things. Then, as (Y/N) started a new game, she felt a falling sensation, as if she just fell out of her chair. She blacked out soon after. When she woke up, she was lying on a bed of golden flowers. She knew this place. (Y/N) was in the game. She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself. I do not own the cover or any of the pictures that will show up in this book• *If you're reading this as a guy please just change the pronouns to he/him/his. I find if a lot easier to just put female pronouns. Thanks! :3 *

At the end of every genocide run, Frisk duels with Sans and wins. However, what if Sans begins to care once more and takes the blow in replacement of Papyrus? Who will lead the dance of fate with Frisk in the Judgement Hall?

#40- TobyFox 12-8-18 #1 JudgementHall 3-21-19 Discontinued. I stood before Sans, he'd fallen asleep. Tears were dripping down my face as I held the knife high above my head.My hand was shaking, I didn't want to kill him, I never wanted to kill anyone, but Chara, that brat, she'd killed everyone, not me. And just before Sans fell asleep, she left my body and I was sucked in. She wanted ME to KILL SANS. At this point, my whole body was shaking. I could hear Chara saying, "Come on, Y.N, kill that smiley ol' trash bag. He's nothing compared to US. NOBODY CAN STOP US NOW!!!! LETS END THIS, HERE AND-""NO!!!!!" I screamed in rage. Sans still didnt wake up. This starts off as a genocide run but then blossoms into so much more. I dont own the cover or any of the Undertale characters, thoose belong to Toby Fox, the creator of Undertale.

*DISCLAIMER* I DO NOT OWN ANY IF THE THINGS I WRITE ABOUT - NOR THE ART This fan fictions takes place after what's called a Genocide Run in a game called Undertale. "Do you think that even the worst of people can change? That even after what they do, anyone can be a good person?" Frisk thinks this is true, but not for her. After resetting after killing every monster in the underground by being taken over by Chara, she fears to get close to her once friends. After Chara threatens Frisk if she didn't kill one of her favorite monsters, Sans the Skeleton, she begins to distance herself from everyone; including herself. Will Frisk figure out how to defeat Chara and have a happy ending once again, or will she succumb to the pressure and begin the slay every monster- just like before? Edit: I own Fuse, but none of the other characters. Original Sans the Skeleton is owned by Toby Fox and any variation other than Fuse is not owned by me. None of the pictures are mine and I found most of them on Google so I don't know who they rightfully belong to. Another edit: I changed the name to Fused

Seven years after falling into Mount Ebott, the final human is finally entering the next stage of life, junior year of high school. Along with the princes and some close friends, she plans to protect her family from the still harsh world outside the mountain and hone her magic. **I DO NOT OWN UNDERTALE OR ANY AUS MENTIONED IN THIS STORY! ALL CHANGES TO ANY CANON CHARACTERS ARE OF MY OWN ACCORD AND HAVE NOTHING TO DO WITH THE ACTUAL GAME! THIS IS PURELY MY TAKE ON WHAT HAPPENS AFTER THE END OF A TRUE PACIFIST RUN OF THE GAME!

The world can't get any worse for Sans after the player left the monsterkind to pay for their own action's consequences. But if given the chance to turn his world a certain way, either for better or for worse, Sans would take it any day. And that's what he did. But he never expected to end up with two skeletons constantly on each other's throats, a mysterious boss, a new life, new purpose, and a new name. Horror. Would things really be better for him in the end? -- [ * Warning : OOC ] [ * Murder Time Trio centric but other characters will also appear/get involved] Art in this story are mine unless stated otherwise.
