How many times have you seen this world, how many resets does it take for you to give up hope? Does anything even matter after all this, does trying do anything? Will the struggle help at all, can I even believe in anyone anymore? The only thing keeping me going now is my resentment.

what if instead of just asta and yuno, there was a third boy named Cosmic. "Cosmic sans"

Takes place after the events of the true ending in undertale (pacifist route) Things finally seem to be going Frisks way... When the man that speaks in hands shows up and resetting isn't an option...

Undertale, Classics AU, meets alternate versions of Sans, but things take a turn between scercts and trust between them.

Ink and Error have suddenly appeared in Undertale. Not a problem, right? Well, it wouldn't be if they could portal back. And, somehow, they're now 9 years old. ...what will they do? -- K, so this is my first story. I hope you like it! -- Ink Sans by Comyet Error Sans by CrayonQueen Undertale by Toby Fox

This is about a human that falls down after Frisk saves everyone. What will happen to this human?

TW: Swearing and slight gore Y/N reincarnates in the anti-void as a Voice... Will he befriend error or will they make them hate their guts? And will they meet other people? Only time will tell. Hello, this is going to be my first book and idk if it's going to be good so meh :v This story was inspired by transported as a voice by Virus_bOi, I obviously do not own undertale and I don't keep up that much with the fandom, so some personalities might be different, but hey. I can just say that it's a different multiverse ¦ ] The cover image is from Shira Wolfiecute on tumblr

cafe au After helping Grillby finally set up his dream space up on the Surface, Blue is surprised (for some reason) when his friend offers him both a job at the cafe and a place to stay in the apartment above it. Eagerly, Blue accepts the offer. And as word spreads about the chipper little helper, Blue ends up with more than he could have ever hoped.

There's one person who found grief after Asgore took their mother's human soul. This person's father blamed it on them. He was a monster. He abandoned her. He said he would kill her if she came around him. So this girl used a device of the great royal scientist, W.D Gaster, and traveled to another timeline. This one followed one rule. Kill or be killed.

The genocide route ended in a bright hallway. Sans lost... And something followed the reset. Itsuka Shidou begins to experience dreams that aren't his, instincts he never learned, and reactions no human should possess. As Spirits descend and spacequakes tear his world apart, an unseen presence watches from inside his mind-silent, tired, and all too familiar with death. This time, there are no resets. Judgment comes after zero.

Abandoned on Mt. Ebott at the tender age of five, young Harry's unsurprisingly died, but Death's always had a weird relationship with his variant... Meanwhile, before Flowey's revival as souless talking flower, Sans makes a discovery under the mound of snow, Papyrus has always wanted to be a big brother anyways. *Edited Summary (29/09/2025)

<SPOILER: DISCONTINUED (yeah, I didn't update for like 4 years)> Have you ever thought about what it could be like as a hybrid? Ever think what it would feel like to lose your parents? To be hunted down every day of your surface life? What if that question could be answered? Well I've got an answer for ya. It can. So, when the underground finds you, let it take you. . . . So...Heya.The names Stitched, Stitched the human and this - if you can't already tell - is my Sans X Reader. That was just a bit of a cheesy intro into the book... I really hope you guys enjoy this! . . . By SupposedlySuicidal {I'm off to bed I need sleep.}

At a genocide run Sans unexpectedly wins against ¿Chara? and something strange occurred, the timeline was thrown into chaos. As a result of this chaos, Sans unknowingly was brought to the world of My Hero Academia where lies a world full of quirks. Now we will find out what journey is to unfold with Sans now in this world. Welp this is my first story... so yea..... im pretty sure I'll make a ton crap of mistakes basically typos everywhere.. sooooo just bare with me okay? I'm also always running on boredom and laziness while writing this. Also this is fucking cringe... Welp um..feel free to drop your ideas I'll definitely consider them... ¯\_(ツ)_/¯ Also this story is definitely not original and inspired by a lot of different other stories that came before it {!Completed} .

Was perhaps from the moment that Monsterkind were hurled down Mt Ebott like trash that W.D. Gaster knew humans were rotten creatures? Or maybe it was instead during the war when he had been but a young child. Forced to flee from all he's ever known as battle raged across lands, then later as he grew up to create weapons of mass destruction. Perhaps, it was before he was even born that he had know this truth. Gaster was, after all, one of the smartest monsters to have ever lived, and most certainly was the smartest monster in the Underground. Because humans were dangerous, after all. They were miserable, miserable creatures that were powerful yes, but miserable. And his next invention would be the bridge to that gap between their two races. No. Rather then gap it was a chasm. He would create the first biological weapon, and once the barrier was destroyed then nothing would get in its way.
