The barrier has been broken. Not due to SOULs, but due to a successful experiment by Doctor Gaster. Now, monsters must assimilate into the human world, where, apparently, the mages are in hiding. Hogwarts school is always a safe place from outside politics, but how will it adapt with literal monsters in its walls?
Featuring Sans as the main character! (Multiple POVs at certain points, and maybe a few chapters with a different main character?)Public Domain

Sans is struggling with an unexpected, and incomprehensible...illness.

Dr. Gaster & Mr. Black (Undertale AU) by MapleInk62

An Undertale twist on the classic "Jekyll and Hyde" Broadway musical. After having been rescued from the depths of the Void, Dr. Gaster resumes his role as Royal Scientist--alongside Dr. Alphys. Now that Monster Kind is no long in need of SOULS, Gaster sets out to begin studying the one thing Humans and Monsters have in common--good and evil natures. In believing it to be greatly beneficial to both races, the Doctor sets out on his new line of research. But, such a pursuit of knowledge can be quite the fine line, and crossing onto the wrong side can be disastrous.

Undertale : Secrets (REMASTERED) by ItIsComic

Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that, despite being so long ago, always finds a way to bite back. A past that defines who he is - but he longs to erase. A past that doesn't let go, it clings to him despite his endless attempts to escape. And when someone finally attempts to uncover the veil, and fails in the process, what happens next? This book is a complete remake of the original Undertale: Secrets that was made nearly 3 years ago. By remake, I mean that this book takes the general plot of Secrets and basically "tries again". This will reuse elements of the original and cut out the parts I don't like while adding my own new ideas, effectively creating a new book. Whether you liked the original or didn't even read it, I hope you like this!!

Moon Light - Undertale fanfiction (FriskXSans-not the main plot tho) by Ombre0

Intro: The barrier was down. It had already been four week. Most of the humans were not pleased with the monster arrival, but since Mont Ebbot was a bit far from the city and that no one ever goes their (for most part of the population at least) they allow the monsters to rebuild their society on it and around it as long that they keep their self far away from the city. With their magic it only took a few days for everyone to be set .It was a new start for monster kind, now they would only need to make their relation with the humans better. Everything was for the best; well it was until the little human that had free the monster got her secret exposed. --- -A/N- -Undertale and all of it's characters belong to Toby Fox -My first language is not english -Frisk is a girl in this story -I don't know when I will be abel to update but I will do my best to not be to slow -Don't esitate to give me some feedback it's my first fanfic :) ---

What Lies Inside (Gaster!Sans x Reader ) by Jaethefallenhuman

"You know sweetheart, lying doesn't get you anywhere with me." He said lighting a cigarette and placing it in between his teeth. Vanilla, leather, and smoke is quite the intoxicating smell. "I'm not lying, also who gives you the right to judge if I'm lying or not?" Something flickers inside me, a warm burning feeling that fuels my anger with this asshole. Walking up closer to me he pins me against the wall, smoke dances around his skull in a vary of swirls and curves. "Let's get something straight dove, I am your worst nightmare and I am your best daydream. I can see right through people, ironic right? There's something about you, I know you're hiding something inside." He really is good at seeing through people, but the thing is I'm not like anybody else. The media I use in this book does not belong to me, they belong to their rightful owners! Gastersans is NOT my original character ! He was created by Borurou Undertale was created by Toby Fox Highest rankings #1 Gatersansxreader #1 Gastertale #19 Gastersans

Universal Surface Angel by Lithriel

Reader insert. What if W.D Gaster didn't just get split between time and space, but actually ended up in your world in an abandoned hospital you called home? Your were a young child he decided to use as experiments to test human determination in said world and breaks physical laws to test human possibility? He knows of the powers you gained from his experiments... all but one, this one allows you to tear realities just enough to teleport into them. Knowing of Undertale you felt bad for the monsters stuck below in their world and wish to help them, but something goes wrong and you end up going to certain AUs and helping them, gaining the attention of some bad skeletons who now desire your power for them-selfish-selfs.

I'm Not Normal! (Undertale) by looloo900

The year is 201X, monsters who once roamed the surface have been banished again after 1 year, no more magic remains from the monsters, except for one child. Georgia Corona. WD Gaster's daughter is the only human with both a human and monster soul, as well as being the only human to teleport, summon bones, blasters and heal monster souls. Georgia is not an ordinary teenager, she doesn't spend time revising, but visiting the underground to see her father, helping him with scientific projects. As other teens would be partying, Georgia would be teaching herself how to control her powers when she's in danger to prevent anyone accidently getting hit by a bone or a Blaster. Georgia has normal, human flesh hands, apart from one minor detail... They have holes in them. One gift from her father is convincing full human hand looking gloves. She doesn't take them off. As the shy teen moves further into High School, people questioning her 'hands'. Would she crumble under pressure and reveal? Or turn dark to keep her secret hidden? (I do not own Undertale - Toby Fox does).
