Fellsans Stories

I have seen multiple people's head cannons and decided to add mine These are NOT cannon, don't take these as fact. You can use these in your stories though Undertale belongs to Toby Fox, all characters belong to their respective owners

so I oh ways want to make a reborn as killer sans, but we're mentally unstable, of course, due to the rest and our past memories, which we can't remember what we were anyway! We know everything and everyone, so why not mess with them. This going to me fun!!!

Underfell is a dark world with the major rule of kill or be killed. Even though children are suppose to be secluded from this rule, that doesn't stop monsters from hurting children. Undyne is a monster who lives in Waterfall. Under the care of Gerson. One day while out on a walk the fish monster stumbles across a baby. Though it wasn't any monster. It was a small little baby skeleton. (the cover is only temporary, until I'm able to make a cover for the story)

Oh Hello- Welcome to this book! I know that you guys are waiting for Another Chance's remake book, but while you're waiting, I have this one-shot book to keep you entertained! Before proceeding with this book, please read my Author's Note first so that you'll get an idea of what this book is gonna be. Edit: I am taking requests! Check out the "Request Chapter" for more information.

One day, something happened, resulting in all of them switching bodies. Now they have to figure out their new abilities, features, and flaws in each body. And figure out who did this and how to reverse it. "I'm sure it'll be fine," -all of them probably

We all know Undertale and it's infamous AU's. The favorites and the...others...let's just say this is a new beginning. For all of them. Or as many as is decided to be put into this story. Who knows what will happen. This story is for shits and giggles, I will try to keep the characters Canon but they will have some aspects that are to help with the plot from going haywire. All original characters belong to their rightful owners. If you have any questions or ideas would would maybe like to see happen please feel free to comment. And if you don't like undertale or the AU's...then why are you here?

A normal human, a normal life.... Except. It wasn't. The year is 2048. There was an... Odd Prion, that's been changing people into... Monsters. You were one of them. It wasn't pretty. It's still around. It's just... More manageable now. Aka; the apocalypse happens and a bunch of skeletons get dumped into the MC's house... But with a slight twist.

She lived in an untouched part of the anit-void. She was hated in every Au she visited. Untill one day... She had told herself that if this last Au hatted her aswell then she would give up on trying. she opend a random portal to a random snowdin. But what she didnt know.... ((A/N)) This story is inspired by of my resalts on many online quizes that i have taken. So i have taken this as an opertunity to feture an Oc of mine that is a lot like me in all ways exept depression level. Hers is slightly higher but dont ask me why. Anyway this book wil feture ((in this order and thrugh out all of the book))--- Horror sans Ink and Error sans Fell sans Cross sans Geno sans Blueberry sans Reaper sans Dust sans Dance sans And a major surpize. (10 points if you can spot them on the cover) this book will have serton parts of- high peek depretion. gore Also all the sans's have gone slightly yandere for her but do not fight each other. Hope you enjoy this book!!!

Feel free to dare and question em Notin that this is my AU so theres gonna be stuff thats based on my headcanons on em All art are not mine credits to the artist except for the gachas- Officially Completed since its dead Sorry no more questions lmao Started: February, 12, 2022 Ended: August, 13, 2022

This is the same as undertale but everyone is mean except flowey. The flower saw frisk fall down and was with her the whole time and frisk gives mercy to everyone but they don't want mercy.

Just like my Creepypasta what if Scenarios.

Here is where I will be putting little bits of my stories. I will be updating the ones with the most votes or comments first. This is just a little thing I'm doing so I can get back into the posting things I write groove! I will update it as much as possible and probs once a day for a while... I have these stories stockpiled.

y'all love mama noot noot? WELL TOO BAD BECAUSE IT'S SANSES TURN TO BE LIKE HIM. ahem. let's get on with the summary, the sanses got turned into kids, and they all were teleported into undertale, and sans had to take them in because yeah, and papyrus, frisk, toriel, asgore, undyne and alphys decided that they wanted to help sans, as well as tease him along the way. And flowey is just curious. Sans aus nicknames: Ink sans-INK Error sans-ERROR Nightmare sans-NIGHTMARE Dream sans-DREAM Killer sans-KILLER Horror sans-HORROR Murder sans-DUST X sans-CROSS Fellswap sans-RAZZ Swapfell sans-RASP Fell sans-FELL Swap sans-SWAP Science sans-SCI Fresh sans-FRESH Outer sans-OUTER Fluffy sans-CCINO Lust sans-LUST Geno sans-GENO Farmer sans-FARMER

He was determined, Flowey knew that, but... as for why, he couldn't piece it together. They just had to handle a world where everyone is against them. (Female Sans x OC x Female Chara)

"Everything about him is perfect. He has good grades, is smart, pleases our parents, has real friends. So why can't I be like him even though we're twins?" - Dream sans Dream constantly gets compared to Nightmare. Nightmare doesn't give a single fuck about anyone except himself (will be explained in the story). Dream is jealous of Nightmare (let's be honest, who wouldn't be🙄). Dream is sad and angsty boy. THEY HAVE A FATHERRRRR, LET'S GOOO. There IS logic!! !NO SHIPS, sorry! Ok so- I discontinued my last story and don't really plan on continuing it ever again unless I feel like it. I'm hungry for angst and the lack of High school sans aus make me sad. This is mainly focused on Dream sans, but other characters' angst will also appear. Warnings are in the first 'chapter'.

So uhm these are the personalities I gave some au sanses and kiddosss

A weird UnderFell sans ends up hosting Fresh, Error, and many others. And by "a weird UnderFell sans" I mean a dumbass that got thrown into a fell sanses body with highschool humor and no sense of safety.

A deal is made in-between two dead souls, one prideful and negative, the other manipulative and numb. Both powerful and trusted, for whatever reason.
