Undertaleaus Stories

Moray, beloved member of the Feisty Five, gets ill without reason and ends up ultimately falling down. Ceroba, dear friend of the posse's leader, gives them a PSA from the Royal Lab, who could find a way to save them. But what is about to unfold is a lot more ghastly than what they could ever imagine.

Cover image made by me. Someone meets their end too soon and meets someone who gives them another chance to live a more fulfilling life. One that they would enjoy despite the problems that may come along. In other words, reader becomes Error.

You were just walking home. A tear in reality split open underneath your feet and suddenly you were falling. Falling Falling Then you fell up and onto the tiled floor of a basement lab. Now all of a sudden you're in another world and surrounded by 6 strange skeletons (plus one's brother). Being terrified of all things horror and monsters, what are you to do? *Will contain mature themes but no smut*

Read me. See what I have in store.

Cover art by sansthepacifist (The story gonna be sh#t/Sh#t writing) (Busy daily life & laziness) (Chapters/Parts get rewritten often) (Inconsistent releases) ⚠️Warning:angst,¿abuse?mentions,depressions stuff mentions,drama. A/N:(despite my horrible writing,still afraid might be little too sensitive/uncomfortable for some y'all) This is a work of fiction and you been warned i seen interesting fanfics about Fgod AU. One particular is "Friends meeting Enemies", although seem like the story either got abandoned by the author or they're busy irl. i want to see Fgod characters interact with their og counterpart. so i made this, This story is heavily inspired by og "Healing What Has Been Broken" made by harrish6. disclaimers:franchise aren't mine & all characters belong to their respective owner. Undertale-Toby Fox Fgod Au-Harrish6 Error!Sans-CQ Ink!Sans-comyet Dreamtale-AU community/JK Something New-rahafwabas Dusttale-Ask-Dusttale Horrortale-AU community/SAS Fresh-CQ Aftertale-CQ Underswap-Popcornprince Underfell-Vic the UnderfellaX Alphatale-Team Lavender A/N:(too lazy to search & credit em all,All characters belong to their respective owners, as for "Au community" ones, don't recommend searching unless y'all matured) Few of these insert arts aren't mine To differentiate between OG Au's and Fgod au. I named the Fgod characters *name*(FM) and the original just OG's FM=Fate Multiverse OG characters will have their canon designs/appearances based on their each creators art style & while FM have fanons. i try to make OG character as canon/headcannonically as possible, but there will be some originalities. A/N:my first time writing fic. Don't expect anything good here. Now, get ready for cringiness and worst grammars you ever goddamn see.

The sanses glared at the new entity at their world in fear but overtime their fears have lessened and started to adopt the new entity as their own. Afraid, of the faith might brought on to them they just braced for the best. This fanfic is made around 2022-23 so don't expect good things especially at the first few chapters of this book! (Also my English isn't my first language so bare with me! Thank you!) <[Requests are always open! I suggest you request at introduction page to avoid confusion!]> !!most definitely the cover isn't mine!! !!Non of the arts,video,AU are mine unless I told you it was mine!! !!credits to the au creators, and Toby fox for creating Undertale!! -Myste-Rey/author (Now Rein!) [!! the story will be updating slowly (very slowly) !!]

What would happen if the Destroyer is a fusion of human and monster SOUL? Wanna find out?

Trying to make a proper Dustberry/Murderswap/Dustswap story now. Everyone deals with the madness of the multiverse in different ways. Some just avoid it or watch from a distance, like Outer or any bystanders of AUs that the trouble intrudes. Some cause trouble like Nightmare's gang and then there's those that try to prevent it like the Star Sanses...Well, that's how it SHOULD be. Many consider it simple like that where none of these three groups overlap. The two sides fight and the bystanders stay away. But...Swap consistently contradicts this system. He hangs out with "bystanders" in other AUs when outside of battle and if not for being part of the Star Sanses, would be a bystander. He befriends Error and Horror or the "enemies" and tries to keep Dream or Ink out of trouble. So when Swap goes missing, Error quickly jumps into action and gets the gang to help him. It lands Dust and Swap into a strange situation and is stuck together, forced to be on the same side. What would this alliance reveal to them when the divide is broken down between them? Read to find out.

A post-True Pacifist Undertale AU about second chances, found family, and two people learning how to love despite the fears that taught them not to.

Chara will never forget the day their life started over. It was like everything in their past suddenly became worlds away, the memories clear yet unreachable. The entire universe had shifted. Except it really hadn't. The world kept spinning; the sun still rose in the east and set in the west. Chara had followed that sun to the demise of their old life, and they were guided by it in their new life. They picked a direction and walked in it, until some other force stopped them, until life began again. This new life, this new world, couldn't be more different from anything they had known. --------- Or: A universe where there were never any human mages, underground, or reset possibilities, just a war between humans and monsters. Chara tries to survive in a small town near the border of monster and human territory while torn between which side they belong to.

what the fuck is touhou. .that was new problem for our new disastorous being - infected sans!(aka jacob). btw infected sans - alphatale by shadikal15 there will be other arrival of alphatale in touhou universe and possibly several unieqe interaction of abilities. This is not serious crossover btw so no need to be argued with how two universe react to eachother?(Technically three since edensphere and Twilight realm is seperated wiki with alphatale).would it be a war between two old realm or coexistence of two seperated world? And for touhou it was obviously from ZUN and both alphatale and touhou project wasnt own by me(except my OC i guess)

this my idea for Lincoln had hero time trio and murder trio time sans and color sans soul and he had phantom of Abbie and deku and Chara and no there will be female chara it just male Chara...

... It's funny how he switched his role in this life, but at the same time nothing really change

attention attention writers and gentle artists this isn't a idea book it's a i-have-too-meny-ideas-yet-i-harber-no-artistic-and-talent-in-writing-but-i-despretly-need-to-see-these-storys-have-a-ending-or-at-lest-readable-because-i-can-never-finish-writeing-out-any-story-i-think-of-so-pleas-pleas-PLEAS-turn-one-of-my-storys-into-a-book book full of undertale content and very cringe-y writing enjoy

(Cover Credit: https://amped-creations.tumblr.com/post/172250573172/phew-jakei-you-are-amazing-and-all-the-hard) As the title suggests, this is just a series of random stories I came up with. Some will be shipping, some will be random scenarios, some will be writing prompts, and some will be chaotic shitposts. Feel free to add ideas in the comments!

Yes(art not mine) (All characters mentioned in these one shots are not mine)

Ink becomes a child....yea! and Error & friends are forced to take care of him... Some of you would recognize this fic from a oneshot I wrote a while ago. Well I decided that I liked it enough to spin it as an actual story, rewriting the original oneshot and expanding upon it :) This Story is meant to be an Errorink fanfic, because I am the #1 Errorink fan, if there are no fans then I am DEAD. Anyways...book cover is mine (lmao)

I created this AU in 2022, but I don't have any digital drawing skills xD So I always used my notebook to draw JourneyTale stories, and the first lore seemed weird and didn't make sense because it involved several other AUs. So in 2026, I created a new lore for JourneyTale. My English is not that good. So I apologize profusely T^T

Short Summary: An Undertale AU, which is a crossover with my The Last Star Seeker series. Long Summary: A young human girl falls into the underground. After being caught and taken up to the castle, they face their judgment. Little did everyone know that this girl had magic like all monsters. The king decides to SPARE her in hopes that she could break the barrier without having to take more souls. Years pass, and Astrella hasn't figured out how to break the barrier, but when she sleeps, she's given messages that shake her to the bone. So, with the help of a funny skeleton, they solve the mystery together and maybe more about themselves too. Yes, this is an oc x canon story 👀

Canvas of Twilight ❲Mortal Muse❳ 🕯 ❝𝐀𝐦𝐢𝐝𝐬𝐭 𝐭𝐡𝐞 𝐯𝐞𝐢𝐥 𝐨𝐟 𝐧𝐢𝐠𝐡𝐭, 𝐭𝐡𝐞𝐢𝐫 𝐥𝐨𝐯𝐞 𝐬𝐥𝐨𝐰𝐥𝐲 𝐭𝐡𝐫𝐢𝐯𝐞𝐝.❞ A new beginning. Pounding echoed in his ears(?), the rhythm matching the frantic beating of his soul. He swiftly turned around, his eyes searching for such noise, and there it was-a door, beckoning him from the darkness. With trembling steps, he cautiously crossed the shadowy expanse, his every movement aching through his skeletal body. As he drew nearer to the door, the feeble light it emitted seemed to mock the surrounding darkness. With a mix of desperation and hope, he reached out, his bony hand trembling as it brushed against the door's surface. The cold metal handle felt like it was stinging his hand. But just as he mustered the strength to twist the handle, sinister snapping sounds shattered the stillness. The noises seemed to circle him, closing in, and panic gripped his chest. His realization-the door refused to yield to his desperate attempts. In his frantic attempts to escape the encroaching darkness, he suddenly stumbled and lost his footing. Without warning, he plummeted into a deep pit, swallowed by its unforgiving embrace. The darkness engulfed him.
