Underswap Stories

Nova is not your ordinary girl. She has secrets that could get her killed and memories that haunt her daily life. Despite that, she tries to live an ordinary life as a new college student at Underground University, a college for both humans and the recently released monsters. After a series of occurrences take place, the skeletons who teach her classes start to take an interest in getting to know her. Will she be able to keep them at a safe distance, or will they discover the truth hidden from the world? Will she be able to protect those around her, or will their deaths finally push her to the breaking point? And just what happened to break her soul in the first place?

He knows he'll be dooming them if he falls, but he's tired, his body is breaking apart, held together on a higher being's whim only. He wonders if there'll be another to replace him. He wonders if there will be none. It's rather silly, really, since he won't even be around to witness that. The crowd, the rage and bloodthirst palpable in the air will ensure that. If he does not fall on his own, others will force him to. Or, in other words, the typical start of Error being forced to jump into the Void one way or another, in this case into the NaJ universe! The cover art belongs to irodimmatcha on deviantart(will take down if the artist asks me to)! Updates will be highly inconsistent. Edit: Now cross posted on Ao3 under the same username!

Crystallize [kris-tl-ahyz] refers to the process where a liquid or gas transforms into a rigid, structured crystal lattice. Or... I look at my other two Avallon and thought 'Yeah I could do more angst with these bois.'

In Underswap AU chara fully gained control in her body and stopped frisk to erase this timeline. she did a pacifist route and in end saved everyone.(includes MK too) Although frisk didn't like this after all she was filled with hate. How could blue can go far for her to change her. Could he able to change her. Also there will be other ships but maybe veeeery late.

This is a senario book including : Undertale Sans, Underfell Sans, Underswap sans, Gaster! Sans, Outertale Sans, Ink! Sans, Error Sans and last but not least Fresh Sans! There is probably going to be some profanity. Comment about any sans you want added and I might add them! (also located on my quotev)

an apocalypse broke out and everything went up in flames nightmare has to look after his little brother and two kids he found named blue and horror he has sworn to protect them with his life but will he be able to keep that promise or will he die trying?

THIS STORY IS DISCONTINUED!!!!

Just some yaoi thing that ran through my head like all the other yaoi and thought "Hey... this would be a damn good book..." Anyway, description, I'll try my best right now. Fresh was supossed to be annoying and Error was supossed to hate him, but he can't help but like him. As for Blueberry, he found him adorable and childish. Blueberry finds Error cute and lonely, Blue understands. I'll say no more, I don't want to spoil it.

Lillith always seemed drawn to earth even more so as she got older but once her father reached the end of his time she had nothing left for her on her home planet. Packing up everything she had she stole a ship crashing into a forest not far from a town called Ebbot. An alien with little knowledge of humans customs just happy to finally be here. What will she do when she starts seeing these skeletons more and more. Definitely something stupid. ~Written in a mix of 3rd person and 1st person~

This is just a little story of my OC x Undertale AUs made purely for my entertainment. Read if you'd like, maybe even imagine yourself as Thia(My OC) Do what you want really just please refrain from hate comments. I'm so sorry if this doesn't make sense. "Years ago, when the monsters fell to the underground, there was a little soul. Not human nor monster but they 'souly' exist with the monsters as humane as they appear. They were the original judge until a certain skeleton spawned from Dr Wingdings's experiment. That's as much as you need to know but feel free to discover more, deep in the underground where the past lies but unknown souls rise. Monsters have returned to the surface with their savour, Frisk. But WHO might the other one be?" !! DISCLAIMER!! NONE OF THE AUS MENTIONED IN THIS STORY BELONG TO ME.

blueberry is tired of the resets. he's killed everyone....even paps just to get enough HP to finally beat the HU- no they don't deserve that title. to defeat the demon...... what will happen in here? read to find out~

(WARNING: Angst, killing) While Dust practices opening portals, he finds himself in Underswap and sees Blue, a member of the Star Sanses. He lets his curiosity get the best of him and watches him for a while. Some would say that this could be the start of a cute and/or spicy fanfiction filled to the brim with smoochies, some funny haha's, and overprotective brothers! Some would also say that this could be the start of something much, much worse. (oOoOO edgy description for an edgy story-)

A collection of one-shot song fics with a different Undertale ships. A song fic is a story that has lyrics in the middle of the story to go along with that is happening. You may request to see a ship as well as a song to go along with them. The full details will be in the Author's note.

This actually came to my mind lol so I'm not sure if it's any good but eh- Blueberry wakes up one day and he hears a voice asking him to go outside and explore the portal that has opened up he heads outside to discover the portal being the curious bean he was he goes through the portal only to discover that there is a sans exactly like him but he's killing off innocent monsters. Blue tries to turn back before it's too late but the portal closes and blue is left all alone with a killer. The two begin to bond overtime dust constantly flirts with blue at times and he starts to get a bit possessive at times blue on the otherhand doesn't know how to react due to dust constantly flirting with him but as time goes on he starts developing feelings for dust but it's not the kind of puppy love you'd expect it's something much more than that it's the type of love they'd call lovesick. (There's lemon in this story if you don't like it then don't read it)

[[Undertale and Stardew Valley AU = StardewTale This is a OC insert story.]] The Undertale crew make it out with the help of Frisk, the forgiving eight year old girl. Little do they know, that their lazy days are over. Curt, the forever smiling and optimistic seventeen year old is the exact picture of joy. He meets Toriel and Frisk when they first arrived in Stardew Valley with nothing but open arms and a guide through the town. And come to love the little farm valley. Everything is peaceful. W H A T L I E S After the ruby eyed demon stumbles their way to the Valley, Curt becomes possessed and is forced to murder everyone with his family heirloom axe. A blue skeleton, unable to hurt the honest, optimistic, human crying in front of him as they battle, is killed close to last, trying to protect Frisk. The child is the last to go, and in the worst condition. Curt is let go of by the demon Chara, bloodied and filled with GUILT. He wants to avenge his friends and family, but finds he has too much FORGIVENESS. He is killed in the end too, but finds he can RESET. (this story is dead, and really old, lol~ kinda cringe, but fun at the time.) #stillhuman #avenging #SOUL=Forgiveness #lightgreensoul #saveChara #IOwnStardewTaleAU

The idol group Blushing bones is super famous and somehow miraculously you ended up dating one of the idols. At least it feels miraculous at first, but the longer you're with Blue, the more it feels like something is wrong.

blueberry hates himself, he lost pride in himself... Fell had tried to help same with classic and Ink... But ever since the incident With Error and Blackberry.

{ "Once upon a time there were two goofy skeleton brothers. A tall skeleton with a relaxed mood and a short skeleton with a hyperactive mood! But... Is there something deeper than the happy coats they show off? What is their story?..." } Just read! I'm sure you'll love every detail ❤️ Written by @BubblySoaps and me!

Its basically the title XD Sometimes there will be two or three chapters to a story. There won't be FULL lemon. Fluff and some mature content will happen. Rarely ;) *Requests are open!*
