Naturetale : reborn as lavender

(As far as I know, no one has made a story about naturetale like this so..and the only reason why I writing one like this is because of fatal error part 5? Or part 4, go check fatal error out on YouTube if you haven't seen it already. This will invole the same names for lavender, thistle, and poppy, the others have the same names from other au's like undertale undyne, but I'll do it my way and possible personalities changes and thistle and lavender are twins in this story) also I looked up flowers and their meanings on google so don't get angry with me ok?What if...someone was reborn in naturetale as lavender? What if...other undertale au's meet naturetale from a complete different multiverse or universe? What if...they ended up in undertale original? What will the others think of them? And why is thistle, gaster, and poppy overprotective of lavender?

The Truce (comic by Jakei95)

THIS COMIC IS NOT BY ME. Its creator took it off of her tumblr page and has declared it non-canon to her other works (Underverse and X-Tale), so I wanted to preserve it here because it's still really good (and also because there are some elements that are still canon and because it's a good introduction to the whole Undertale AU network in general).This comic takes place in the fan-made multiverse related to the video game Undertale, and contains several characters not made by this comic's creator (Ink!Sans by Comyet/Myebi, Error!Sans by Crayon Queen, and CORE!Frisk by DokuDoki). It is also a prequel to the comic X-Tale, which takes place in an Alternate Universe that Jakei did create, as well as her Alternate Universe crossover animation series that follows X-Tale, which is called Underverse. All of these (although sometimes hard to follow) are worth reading/watching for any Undertale fan.If you want to learn more about some of these characters' backstories that aren't explained in this comic, start here https://undertale-au.wikia.com/wiki/Undertale_AU_Wiki or here https://undertale-au-fanon.wikia.com/wiki/Undertale_AU_Fanon_Wiki (these websites also contain spoilers for X-Tale and Underverse, so if you plan to read/watch those, then don't go to those pages)

FGOD Error in Dreamswap (COMPLETED)

NOTE: A old fanfiction created by me during Covid 2021-2022 back when I was invested in Undertale/Undertale AU's. If you're looking for angst or topics being covered more seriously this story may not be made for you as it's mostly light hearted and written during long car trips or when I was bored. I would like to thank you for all the support this story has received despite it being written with poor grammar and little to no plot, and it always makes my day reading your comments left on the story, (yes, I still read them) thank you all! It's all thank you to you guys as the readers who got this story to 82k reads and 2k votes

I'm...swap gaster?

Yeah sorry gained an idea on if someone became swap Gaster Also they may be apathetic or just confused on their feelings and MAYBE Autistic, I may be a bit wrong on apathetic or not completely accurate idk yetAnd it's a huge maybe on the autistic part it might be mentioned at some point or notI usually don't do this kind of story on something like using apathetic and perhaps autistic but i decided I wanted to try.And the maybe confused kind feelings is not knowing what they feel or if they even feel anything and all

Reborn as Ink sans (discontinued)

Literally what the title is. Also, I'm going to add a picture for the cover, don't worry. I just haven't gotten to it yet. Enjoy! No idea if this will be mature or not I do not own any of the characters beside Logan and a few other people. Also, this is inspired by all the other reborn as Ink fanfics I have found, and a few other reborn as *blank*.

An Error's Doll

You didn't have a bucket list or anything, but you wished you could've at least read a few more fanfics or done literally anything fun before dying. Oh well, at least you didn't have to socialize-Wait. Since when did dying mean becoming a doll in an Undertale multiverse? How did this happen??This was inspired by a ton of reborn and reincarnated as Undertale characters fanfics and some other awesome stories! The main inspiration was 'Little Dream Doll' by KassyxTheDumbFox, and they got the idea from Firehedgehog's 'Idea Factory'.Beware, this story is fan fiction and is not canon, will include ooc characters, and I don't own Undertale or any of the characters, if you don't like that please read something else. This is my first story so there's no guarantee I will update regularly if at all, this is mostly self-indulgent. Btw, the cover's mine, please don't use it.

Mental Disorders

As people may or may not know, I write vore stories. And I just had a big brain idea. I have a few Mental Disorders myself, and thought, "Hey. Why don't I make another Sans AU core story, but y/n has different mental illnesses." So, I will start with Freaktale and if you like, please request a Sans and the disorder Y/n has. I will try my absolute best to make it as realistic as possible. So in the request, please describe the disorder so I don't mess up. If I do, please tell me and I will fix it. I do not wish to offend anyone that has any of these disorders, as I may have a few myself. Thank you, and if you are about to read I hope you enjoy!

Misunderstanding

The concept to this version of Error belongs to harrish6! Please, go check them out! The fighting between Ink, Error, and the Balance continued on and on. Ink just wants to stop Error, PERMANENTLY. But, Ink's morals get in the way. Ink must know why Error does this, the mystery can't go on for any longer. If Ink were to just off Error, end him, before getting to know his reasons behind destroying, it would haunt him at night. Ink calls for an all out Sans meeting, meaning hundreds, no, thousands of Sanses were to meet up in one place. Of course, there are so many more Sanses than this, but these thousands would mainly consist of the main Sanses with the largest Aus. The plan they come up with, Ink doesn't believe it will work. None of their other plans worked, but then again, none of their other plans had been anything similar to this. Error, on a somewhat same hand, is about at his edge. The VOID is practically calling him, but he knows he can't leave yet. He can't leave with the heavy weight on his chest that is his story. He needs to confide in someone, though he knows he can't do that. No one would ever be so kind to him as to listen. Sure, Outer talked to him a bit, but that was mainly spying information that Inky wanted. Error is hardly willing to do anything for the Balance anymore, but he still goes on. And on, and on. Until Inky's plan happens upon him. This is new for him, very new. He doesn't think this is real at first, possibly it's all a dream? No one would ever do this to help him, would they? Surely, surely this is just a trap waiting to kill him. ~~~ Basically, if you have read harrish6's books, you probably know about HWHBB!Error. This is him before Classic and Ink's original plan to attack Error with all of the Sanses. Ink finally uses morals for once.Credit goes to AuthorAirur for the first 10 chapters.
