HAZE by anonemones

Written: May 10th, 2017--June 22nd, 2017 reposted from my AO3, anonemones; contains both part one and part two. After a year of living on the surface, monsters and humans have gotten along well, with (mostly) everyone adjusting to the many changes without much trouble. However, events take a strange turn when Sans and Papyrus--both of whom have been acting unlike themselves--go missing, supposedly without a trace. In their place are two monsters who go by the names of Wingdings and Aster, twins, claiming to be the lost Royal Scientist. Everyone is thrown for a loop, especially as nobody remembers a Wingdings or Aster--or, as they claim to be, "Dr. Gaster"--nor do they remember a Royal Scientist before Alphys. And with Sans and Papyrus missing, things don't look good for either of the boys. As their friends search for the missing skeletons, Wingdings and Aster work together to uncover what's happened while they were gone, as well as what might've caused everyone to forget them in the first place. But, trouble lurks within the shadows, as the Void closes in on them once again--refusing to let go of what belongs to it. And unfortunately, the Void is not the only thing after the boys' lives.

Broken Souls by James_Bond_Pig

Bringing people back into existence doesn't generally have negative repercussions. Not for an entire world at least. So why don't we use the same idea for an all powerful entity and see what happens? Unfortunately, this world might not be up to the challenge. ---- What's this? An Undertale fanfiction? Yes, that's exactly what it is. This takes place after a True Pacifist route so spoilers if you haven't played it (which you totally should, go play now!) Currently being edited...

Love Me Instead [Sans VS Gaster!Sans X Reader] Part 2 (EDITING) by PineappleGalore001

Please read part 1 if you haven't! When a mishap in a reset happens and a character from another version is transported into the current world and timeline, what happens? Gaster!Sans, bad-skele-boy from EchoTale is confused to see that he had landed in a different, yet familiar world: Undertale! Apparently, in meeting with his 'original' version, they seem to be OK with one-another, UNTIL... (Thank you, @yourebluenow for the cover!) If you have not read part 1, look for it! It has the same name and cover, but without 'Part 2' on the title.

Daybreak [ Error!Sans x Reader ] by morrow-

Gone. In a single moment, in the blink of an eye, everything you have ever known or cared for is eradicated. Hopes and dreams, traditions and stories that date back centuries have been erased without thought or care. Nothing matters and no one will ever live again to pass on the memories and stories of what was lost. Except you. You are the anomaly, the glitch that survived when all else could not. When your universe was destroyed, you found yourself stranded, alone, afraid in a white world without end. But there's little time to rest when you discover that your universe was merely a grain of sand on a much bigger ocean. Whole other worlds thrive in different plains of existence, and they're all going to war. In a desperate power-struggle for the upper hand, you find yourself an unlikely ally. The future seems certain, chaos will win and the universe will be plunged forever into violence and bloodshed. And it will take a lot more than a miracle to win.

Changing The Game by Starlessz

One month before Frisk falls into the Underground a different human falls, someone that is not from this world, but from ours, and now they have the power to change the world as they please. What will they do, will they do the genocide route and become a megalomaniac? Nope, they want to be everyone's friend and get their version of a perfect ending.

Undertale:Secrets by ItIsComic

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book! Cover art by someone? I couldn't find the original owner :( Undertale by Toby Fox

The half breed and comic skeleton (Sans X Fem!reader) by FormSans96

This is a rewritten story of mine, I have changed the story to a X reader as well. I am a half breed. I am half human and half monster. I believed no one would ever love me like normal people would for each other. That was until I met this one skeleton, who has his own secrets. I can only hope.

Reincarnated as Horror Sans by Cosmicstars08

From Kind to Cold by JimmySMASH4daWIN

Underfell Skelebros backstory! Technically a prequel to my story, "A Three Way SWAP," but you don't need to read that to understand what's going on. Takes place in the world of Underfell. We learn what happened to Papyrus to make him so cold and distant in Underfell. WARNING: MILDLY VIOLENT AND MENTIONS SUICIDE. GETS A LITTLE DARK. YOU'VE BEEN WARNED.
