There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox.

[ Sans AUs x Reader ] This wasn't what you expected - this isn't what you wanted. You wanted to rest, to finally, finally breathe, relax. But apparently life had other plans for your sleep deprived self. It wanted to trap you, it wanted to make you see - to make you realize, you're life isn't what it seems to be. You didn't want to take part in this chase - in this game. This isn't what you wanted. But this is what you needed. And some skeletons are here to join you for the wacky ride. I do not own Undertale, Toby fox does. I do not own any AU's in this story unless stated otherwise. I only own the plot of story.

You're Frisk's friend, who jumped down the Underground. Not wanting to leave him alone, you jumped after him. After a lot of pacifist routes and resets, you woke up in a place which seemed to be the ruins you knew, but soon you realized that you were wrong. You'll switch between different AUs, everytime something serious happens. Like a reset or you die. Or even something else happens? (Y/N) = Your Name (H/C) = Hair color (E/C) = Eye color (S/C) = Soul color (everything except red, becuase you're not determined) (F/C) = Favourite color This is my first fanfiction, so don't think too much of it. Even though, I don't think that anyone would ever find this. XD

"How can Cupid... how could you be so cruel?" I curse lowly. Who could have imagined something like this happening to me? It had been so long since everything happened, but somehow the pain in my heart never left. The memories starts to flashback into my mind as I start to process what is happening in front of me, and why my past heartbreaks are all gathered at the same place. Nightmare, my childhood friend and first love. My first ever heartbreak. I tend to find him in everyone I have loved. He was cold and unpredictable but he was also warm and considerate at times... He was complicated but I loved all of him. Error, the one I chased over and one I was not willing to give up. He stood up from the rest and gave color to my world. All my poems were dedicated to him and him alone. Dust, possibly my other half. He felt like my soulmate. Everything about him made me feel like we were meant for each other. We shared the same interests about everything but I was wrong about one thing. We didn't share the same feelings. His heart belonged to my best friend. Killer, a flirty guy who people often rumored as the playboy. Most girls had fallen in love with his charm and personality. I was one of those unfortunate ones who fell right into his trap. But I... I saw something in him that other people couldn't see; there was something beneath those sweet grins. Horror. My comfort. My home. The one who filled the gap. The one who I think of every little nice thing. I love him so much to the point where I feel like the pain that would come with it would be worse than death. It had to be avoided. Cross. I was always drawn into him. He was my best-est friend. The one who I can count on everytime. The shoulder I can lean to when needed. The one who made me feel like I am the best thing that ever happened in his life. He was perfect while I am just... me. So why did I have to see them again? Why now? Love is not something I want to go through again... never again. <\3

Everyone in the village loved Dream, and he loved everyone in the village. But for some reason he feels closer to you. Hopefully something won't ruin that....

#1 of 61.7k tagged with Undertale 12/06/24 After drowning as a human, Ashe reawakens as a DustTale variant of Sans. With his ghost Papy helping keep him from falling into suicide a second time, Ashe slowly learns he can have fun, and what's more fun than fucking with the Star Sanses who have totally mistaken him for the 'evil' Dust Sans?

[THIS IS A SEQUEL TO MY OTHER FANFIC "WHEN TWO SOULS MEET!" If you haven't read it, I would highly suggest it--the story won't make much sense otherwise.] Sans has finally found someone he can trust--Frisk's sister, the eighth fallen human. After months of step-siding and awkward interactions, the two are finally a couple. Things are slowly falling into place--there are no more resets, and Chara and Flowey have been a lot more quiet in the last few months. But things can't stay this way... can they? Note: The story was put on hiatus early on, and updates are now very sporadic. Despite that, it's still a labor of love!

Chance didn't like how the story of Dreamtale became. So in one of his famous break ins, he decides to do another flip you at Fate by giving the twins something they didn't have before. Or more accurately Nightmare. Chance may or may not have changed the spirit of Dream with another in his escape attempt. One that was still living. Whoops? ___________ A tale of a poor soul from our world who has been placed into Dream's fate. Would Chance succeed in changing the fate of the twins? Or will it all be for nothing?

"the healer likes t' sleep. like, a lot." Axe looks at the sole female AND human member of Nightmare's subordinates. She was only ever awake for about 8-10 hours a day, rarely ever 12, it was both fascinating and irritating at the same time. He was damn sure humans would be awake for more hours than that, he even asked Murder at the time if it was normal. Said skeleton didn't give a single care though, his words: "who cares, makes her more tolerable. 'sides she gets her job done." The cracked skeleton just couldn't shake off the feeling that there was more to it than meets the EYE. ━━━PHOTO CREDITS: Whale鯨豚 [@Whale5511] on X! ━━━MOST NOTABLE RANKING: #1 in sansxreader, horrortale, something new and badsanses on 23/12/2025 #1 in undertale on 25/12/2025 #3 in bittersweet on 24/12/2025 #5 in reader on 24/12/2025 #19 in sans on 23/12/2025 ━━━━━━━━━━━━━━━━━━ DATES PUBLISHED: 001 ━━ July 29th of '25 002 ━━ July 30th of '25 003 ━━ August 1 of '25 004 ━━ August 3 of '25 005 ━━ August 6 of '25 006 ━━ August 8 of '25 007 ━━ November 8 of '25 008 ━━ December 22 of '25 009 ━━ December 23 of '25
