Alphys Stories

Your favorite skeleton is back at it again... and again... agagaagaag Sans has had enough. Everyone is at the surface, holding their own jobs and lives. But... Sans can't ever let it fade from his mind. The dust. The cries. Watching the screen with Alphys as a child just rampaged in the underground. He is going to snap. He is mad. He is sad. He can never forget. Cover is NOT mine, find it online if you want ::Rights for the original concept and media 'Undertale' are all under the jurisdiction of Toby Fox. All other workings are done by me.::

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)

If given the chance, would you start over? After falling into a timeline where nobody was murdered, his mother never died, and his father was never erased, Sans should be ecstatic that he has a second chance with his loved ones. But there is no denying the trauma he'd been through, either. Everyone is supposed to be dead, after all. What if Frisk comes back to take it all away again?

Saitama gets stuck in the Underground. Well, this'll be interesting!

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.'

It's a fall into darkness... a world of starving monsters. All that would do anything to survive. And that includes catching a human like you. Horrortale. Inspired by Undertale, based on the Horrortale universe. Credits to Toby Fox and Temmie Chang for their respective characters and Sour Apple Studios for creating Horrortale. Just a small warning that there are some grusome imagery. Continue reading only if you're okay with it! (Art credited to it's respective artist.)

How many resets has it been? How much suffering have you caused? Is it worth it anymore? They finally made it to the Surface. Everyone was supposed to be happy, but when Sans is found unable to wake up the heavy truth settles. He had Fallen Down. Papyrus can't imagine why. He can't lose Sans! So he goes in search of answers, only to find more than he ever bargained for.

Sans and Papyrus were just trying to have dinner. They didn't expect things to blow up (literally). Now they have a destroyed machine and a young babybone that they suspect as a Shifter. Where did they come from? And who's life privilege they need to remove? Because this babybone is clearly been abused or worse. Now then, where's that parenting books Sans been storing since Papyrus a babybones, he's definitely need a review if they want to keep the kid from getting killed. At least the kid's adorable...

Kris, the only human living in Hometown, has a normal life there with Toriel. He and Susie, an unlikely friend, entered in a closet which led them to the Dark World. Now he meets Ralsei, a princess that waited her whole life for the heroes, and a tale of Love and Hatred is about to begin. ~~~~~~~~~~~~~~~~~~~~~~~~ As you may have noticed, Ralsei is a female and Kris a male. I don't own any of the characters, including images and music used on this story. Most of them are from Toby Fox. May contain lack of cohesion because English isn't my first language. Not everything written here is canon and the book itself isn't of course canon. It's mainly a novelized version of Deltarune but with the lovely Kris x Ralsei ship. Enjoy!

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 👀

"Don't judge a book by its cover, doll." Medusa wasn't really the most liked monster in Snowdin, though she didn't particularly care. When Frisk begins yet another run, they are introduced for the first time. While being stereotyped, she goes to one flame haired man to talk to.

WARNING: This is not the official book adaptation for the 2015 video game Undertale. All characters, settings, and original plot all belong to Toby Fox. If you have not played the game, I would kindly remind you to play the video game. (It's one of my favourite video games). This is only a fan-fiction book for my writing skills and to deepen the Undertale themes from the game.

Well, you'll just have to read and find out.

It's very important that you follow each and every one of them!

A head canon based " Day in the life " styled story about Susie. This ones a little longer than Berdly and comes in two parts. Part one is before the events of Berdly whilst part 2 is the same time. Trigger warnings: unhealthy living situations, mentions of alcohol, sexist slurs and cuss words

"SAVE The World" is a fan-fiction story. Based on Toby Fox's best-selling game, Undertale, the reader follows Frisk, a human from above who falls into the underground. Rumors say that a war between humans and monsters was held long ago, the humans being victorious, trapped the monsters underground. SAVE The World is an inspiring story with a nice story-line, a choose-your-own adventure style plot, and various other plot-lines that are yet to be discovered. Note: None of these characters are mine and are the possession of the one and only Toby Fox, this book is just for plain fun, and to express my love for Undertale. Other Notes: All The Characters in the book are above 18, Frisk's gender is not specified, but I will refer to Frisk as 'she' or 'them' sometimes. Another Note: I don't update too often, but I try when I can :3.

I'm not going to be very active but I'll post at least every month and try to come up with something- Just a note I will include 14 Characters from Deltarune including Kris Ralsei Susie Queen Spade King Lancer Berdly Noelle Swatch Tasque Manager Jevil Spamton Rouxls Seam Also adding for lightners because I might need it Kris Susie Alphys Undyne Berdly Noelle Napstablook Papyrus Sans Toriel Asgore And someone random because I said so 🤯🤯 Since there are only 12 Zodiacs there will be 2 bonus characters for each chapter. Except for the lightner chapters Thanks for reading!

The title says it all. Only for audiences 18+ REQUESTS {OPEN}
