An UnderTale AU by Raillison, which takes place in a post-pacifist timeline that happened after the True Pacifist ending in UnderTale, also entitled as UnderTale:The Derivation in its first season.
After the freedom of the monsters had finally taken over, years had passed due to the harmony they had with the humans on the surface. On the other hand, Frisk, the main protagonist takes a move after encountering a bizarre dream that they had,or much more as a nightmare. The salvation of everyone matters to them the most, so they knew they failed to save three people that needs it the most.
Since this au first takes place on the main universe, on the other hand, only Frisk and Sans knew the evolution of the Multiverse- infinite amount of different universes that evolved through the coexistences and ideas the creators have developed by knowing the main universe. Frisk knows there's something out there, waiting for them...
And deep in the "Multiversial Timeline Save Point",another person is operating and modifying the status and details of every universe.
Until...one time...
They noticed there's something wrong....
There's some kind of anomaly trying to intervene, and will be the reason why each and every other timeline began to shatter and be gone forever.
Frisk is convinced...
Will they save everything with that person?
Or will they let the whole Multiverse-including theirs, to collapse?
Different worlds...different timelines...different routes....
They're out there...no matter what kind of condition....
But still...
It's time to SAVE the Multiversial Worlds!

Undertale:Secrets
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.

What Went Wrong?
~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~Complete
Underopian
An Undertale AU with the setting being a dystopian city. You follow Frisk on their journey through the dangerous Underground, meeting friends and foes. Frisk also meet a mysterious character that follows and helps them throughout the Underground, although, it seems they may have strange intentions in the end. There are drug and alcohol use included as well as strong language which is why it's marked as mature. It's finally finished! I started this at the beginning of January and I got it done! I'm really happy with how it turned out and I hope you all like it too! This is the first story I'm writing so I'm not expecting a lot from it but I hope who ever finds it enjoys it! I'm also planning on making other stories from this. This will be the main canon story, but I am also planning on making an epilogue story of the Genocide route. It will be named as canon as well of what I have in mind right now, but things may change, who knows, see what happens when we get to it! Also huge thanks to everyone who read part of my story!Complete
UnderAsriel
Chara has one objective: RESET back to when they themself fell, and save Asriel from his demise. With all the Genocide Runs the now-free Frisk goes on for them, they're able to amass a big enough collection of SOULs to do exactly that. The only problem is, Asriel remembers everything that happened when he was Flowey. And he isn't too happy about it... In this new timeline, Kelsa, the SOUL of Bravery, falls into the Underground shortly after Frisk. Determined to save her only friend, Kel teams up with a mysterious flower with a face to find them and rescue them from Asriel's notorious freezing chambers. Betrayed by many, and uncertain who to trust, Kel finds herself in the midst of an iron-fist dictatorship, fighting to restore the Underground to the peaceful place it used to be. But... all is not as it seems, and there may be things about Frisk that Kel will wish she'd never discovered... Cover art by yours truly :3 This story takes place after the events of Underhappened. You may wish to read that first if you haven't already :DComplete
Undertale; Despair AU《OUTDATED》
THIS IS THE OLD VERSION, YOU CAN FIND THE REWRITE ON MY PROFILE, THIS ONE IS REALLY BAD, TRUST ME. THE REWRITE ISN'T DONE BUT IT HAS QUITE A FEW PARTS RN What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How would a few children manage to defeat them? Could they even do so? How would they free the monsters? Can they free the monsters? How will they change the monsters' fate, for the better, despite all the odds being stacked against them? What if there's more unanswered questions within this, even after the ending? -------------------------- THINGS TO KNOW BEFORE READING: No fanon ships will be in this (ex. no Papyrus x anyone or Toriel x Sans. Asgore x Toriel (in the past) and Undyne x Alphys occur) . In this AU Chara is still the first ever human, just set in Frisk's time. Basically all the other characters from regular are there, just some events haven't taken place yet. Chara fell in 2005, Frisk fell in 2015. No other humans fell in between. THIS IS NOT AN X READER IF THATS WHAT YOU ARE LOOKING FOR. ITS A FUN STORY WITH A HINT OF SADNESS. I WILL NOT EVER WRITE AN X READER FOR UT OR DR, NOR MAINLY SHIP STORIES ⚠THIS IS ALL AN ALTERNATIVE UNIVERSE. NOTHING IS CANON. NOT EVERYTHING IS DIFFERENT. PLEASE DON'T SAY "Chara fell in 201X not 2005" OR ANYTHING, THIS IS AN AU. NOT A CANON SEQUEL. THANK YOU⚠ Credits: "UNDERTALE" created by Toby Fox and Temmie Chang.

UnderVerse: COLLAPSE
NOTE - Although I recommend reading my anthology story "Depths of The UnderVerse" first, explanations will be in place where this story can be read on its own, separate of the anthology story I have written, so don't worry too much about it if you're reading this one first... Sure, Some lore won't make sense at first, some characters being there won't make sense, but they can be explained away if you wish to make sense of it all- After an Anomaly presented itself, Ink and Error have disappeared seemingly from the picture, leaving the UnderVerse itself in a state of defenselessness... As such... This has led to calamities coming forth... Causing a collapse in the UnderVerse.... Something is making this all happen.... Core Frisk, the protector of the Omega Timeline and of AUs lost to time itself, by keeping such people alive in her void, along with allowing visitors... Is left to pick up the pieces of the collapse... However, Core Frisk can't do it alone... Whatever calamity occurs, one must need help to ensure the safety of the UnderVerse Read the other stories from the UnderVerse - Depths Of The UnderVerse - UnderVerse Collapse - UnderVerse Defiance (Lemonade-Demon) - Tales From The UnderVerse (Lemonade-Demon) https://www.wattpad.com/user/Lemonade-DemonComplete
Posttale (English UT/DR AU)
This story takes place after the events of the pacifist ending of Undertale, where all the monsters have already left the underground. However, that won't stop problems from starting again; Frisk and his friends will have to face a new threat. DISCLAIMER: This story is based on the fact that the first human fell underground in 2015 and the last in 2060. Here, Deltarune is a sequel to Undertale; therefore, Posttale is not a copy of TobyFox's creation, but an adaptation, or what is also called an "AU." Because of this, there will be things that are different from canon and adapted to my personal preference, with no intention of disrespecting anyone; for example, the gender of the humans: Kris: M Chara: F Frisk: M Don't like it? You can leave. Understood? Great.

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.

Lost Souls (Chara x Frisk)
Falling into a world, where monsters only care about killing all humans, Frisk has to try and escape. But with barely any friends, and with each death comes a new flower growing on them, they find that this wish is much more difficult than they thought. But, what happens when their determination becomes to much for only one person to hold? (This is a Frisk x Chara fanfic, the are both agender and will be referred to with they/them pronouns. This is using the Flowerfell AU, which is a combination of two different AUs; Flowertale: which is when every time Frisk dies, a golden flower blooms somewhere on their body, and Underfell: which is that all the monsters are more set on killing Frisk instead of mercy, and it's much harder to survive, and Flowey is actually kind and helps Frisk. The plot is created by me, but credit goes to Toby Fox for creating Undertale and whoever created the Flowerfell AU. Cover art is not mine and credit goes to the respective artist.)Complete

Saving Them (an Undertale fanfiction)
The barrier is broken, monsters and humans are living in peace, everyone is happy except for one person. Frisk has been getting waking nightmares about not saving Asriel. They want to save him to erase all guilt and to be with their friend. But Asriel isn't the only one that needs to be saved. Something, someone lurks inside Frisk's soul. Someone deadly and has a hunger for power, and can kill anyone they want. A/N Frisk and Chara are both gender ambiguous in this story. Also there will be a little bit of Frisk x Asriel in this story, but this is not a Frisk x Asriel fanfiction. Credit to @karinacat59 for the cover. Undertale belongs to Toby Fox and none of the characters are mine.Complete
FurtherDown
Was this truly the last RESET? Sans wondered. But he knew only Frisk would tell, only this young girl would decide his future. He hated the thought of it at first, but hatred began to grow numb after he figured out he had no say in his own future. He had to admit though, Frisk was pretty reasonable, it was Chara who was the maniac. But she was gone now, so what was the anticipating, eerie, feeling that he had in his bones? The feeling that something wasn't right, of course, this timeline was already incredibly strange. The feeling sat in his in the pit of his stomach, tying itself into knots, until that fateful rainy day when all of his questions would be answered. So basically, this is a fanfiction of a fancomic of the game Undertale. Look, I'm gonna admit, I'm little stuck in the Undertale fandom, so this is my of slowly crawling out of it. Anywho, I strongly suggest you read the fancomic which this fanfiction is based off of, DeeperDown, before reading my story. Here, I'll give you a link. http://gettingdeeperdownwithundertale.blogspot.com/ Anyway, enjoy the story, it took me about 11 months to write, so please consider enjoying it, seriously. - Ya Boi, FoxComplete
Undertale - Life Outside the Loop
It's been seven years since Frisk set the monsters free from the underground, seven years since her choice to return to her human family. Magic is seeping up from the ground, slowly granting humans magic, spelling danger for humans and monsters alike. What's worse? A dark, murderous monster with terrifying power to possess is powering up through the genocide of alternate universes, bent on the destruction of humankind.

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 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.

Frisk has freed the monsters of the Underground. Finally, monster kind is allowed to return to the surface. It's been 3 years since then. Yet the monsters still struggle to find their place within the world. Most accept the monsters, but there are those who wish nothing more than the complete annihilation of monster kind.

All The Dead (Chara X Reader)
"Psychotic tendencies..." As a child, Y/n L/n had a good life. She was always complimented for her h/c hair and e/c eyes. She had a loving little sister and a caring mom and good friends. So, if she had the perfect life, why did she throw herself into Mt. Ebott? When Y/n awoke in the Underground she immediately noticed how much nicer the monster's are. They all brought a smile to her face and she felt at home. Toriel was always a mom to her, Sans and Papyrus were brother's, and Frisk was her best friend. She couldn't have ever wanted more. So, why did she kill all of them? Her and Chara had killed everyone more times than countable together. Chara was happy they found someone they could connect with, and Y/n was happy someone accepted the fact that she was a killer. They got along perfectly, the best of friends! Murders, of course, but still best friends. And they were always just friends. Right?Complete
