I haven't used this account since I was 13 years old why not return to post Pirate Gaster Fanfiction?

Subaru Natsuki, a shut-in meet who did nothing but play games all day since he was in elementary, playing whatever kind of games in his room. One of the games he had played was a game called Undertale, he played it once and loved it, the characters, their depth, the different endings, and how diverse they were. After Undertale, he played Deltarune, he loved it as well, especially after getting all the endings for it and seeing how they executed the ending even better. And then, the final two games he played were Undertale: Yellow, and Undertale: Yellow and Red. And after playing the games, there was one thing that he wanted to know more about, and those were the Seven soils of the Seven dead children. And so, he looked into the souls, more about them, more about how they could be used, he even watched videos on Glitchtale and more on the Undertale/Glitchtale wiki about the seven souls, all for the purpose of creating his own fan-game for undertale, and so, he picked up coding, and decided to begin a test run. But he decided to go get some food first because he knew it would take a long time, and so he went to the nearest convenience store, but didn't know that his life would take a turn for the better or the worst... I do not own any characters that appear in this book, have fun reading it and help in writing is always appreciated

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 👀

A self insert of the author of this story turns into a self aware Dreepy with all his memories intact in the Pokemon Mystery Dungeon universe but instead of becoming a hero that does dungeon crawling, he becomes a dishwasher in Spinda's Cafe where the story turns into a surreal workplace sitcom full of: fourth wall breaking, reality warping nonsense, and pure internet humor. IBADTADITPU may include:

The future of this timeline DISCLAMER All the main characters belong to Camila Cuevas. THE ADDITIONAL CHARACTERS ARE MY CREATION to give my idea on the future of Glitchtale having said that I hope you like it if so I invite you to follow me and leave a positive feedback ;3

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.::

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)

WATTPAD IS THE ONLY SITE THIS BOOK SHOULD BE ON. You are an ex-military 21 year old girl. You and your sister Frisk are on a hiking trip. What happens when you find yourself in a earth quake and fall in a giant hole? who will you meet?......Read to find out! (A/N) I don't really know much about Gaster sans and others but I try XP (A/N) *Bloody hell! I suck at introductions! but may I say I think I did good! bye Lovelies, and enjoy!

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.

Genuinely only posting this to see if a very old roleplay is on here.

Once Upon a Time 8 children have fallen from the Surface world. 7 children were killed by Asgore, 1 killed themselves. 6 souls are Trapped in the Asgore's Castle, 2 are trapped in the Ruins. 1 will save them all. Clara. The 9th Human [ Book 1 of the Calamity Saga]

after the barrier was destroyed all the monsters in the underground were free and happy but for the humans well they weren't happy at all not even in the slightest because as it turns out the only reason why they created the barrier was to not because they hated the monsters but to keep four Pacific creatures trapped inside that's a danger to everything and everyone and now there free

so this is an old story i did when I was bored like year ago? found it in my docs and started to fix it up some, hope you like this as filler in between working on my other book lol oh yeah also its a soulmate au because their good and i like them a lot Cover art by me

This is a fanfic of my own adaption of the Storyshift AU from Undertale. I found that it was a little strange that only the main characters of Undertale got shifted, so in this Fanfic, pretty much everything will be different, while hopefully staying true to what's good about Storyshift Enjoy! Or I'll give u hava >:3 Have nice day!

i made this a while ago dont judge ;-;

Can they recreate the world to a better place for living and the non-living? Note:the included ships that you may see are Alphyne and Asgoriel. Sorry for the other fans who like other ships. I may have wrong grammars in the story, so please be aware of that and just call me to change it. This story has been inspired by Ninnymouse42 "Undercorrupt" and Tomorrowland. Check these two out! You'll like it. Also I do not own the cover and the game.
