I have an Idea for an Undertale AU. And apparently, it's a good idea? So here, have a book.

---

Long ago, two races ruled the earth. But when a plague of corruption swept through one species, causing a half of their population to attack the humans, the humans thought it safer to banish all the monsters underground.

Now, the Underground is a Battleground.

The battleground of the Pure and Corrupt armies.


This Is UnderCorrupt.

Determination - G!SansxFrisk by Toasty-Writer

Frisk just wants to save monster and humankind, but does she have the determination to do everything she wants? Especially as she has now been blamed for the terrible crimes committed by her sister. G has stopped caring, but can this infuriating woman who becomes his neighbour pull him back into the world and seek for justice again. I'm so bad at descriptions :/ I'm delving headfirst into fanfiction. You guys may not like this story or even read it but I'm going to try. This is a Gsans and frisk story, there will be an attraction between them but it may be slow :P I do not own the characters or their respective AU's. I'm simply throwing my own twist into the mix hoping you like. I do not own any of the art featured in this book, they are just all amazing. Will involve some moderate language, violence and trigger warnings, hence the mature rating, I will warn at the beginning of chapter if there is a trigger warning.

Undertale x male reader - A bullet to the head *Season 1 + 2* by kinder1000

"A man nearly kills you and your response is to track him across the whole underground... When you set your mind to something you get results... I like that."

Sacrifices (Undertale FanFic) [COMPLETED] by Brynwyth

Frisk has freed the monsters of the Underground. Finally, monster kind is allowed to return to the surface. It's been 3 years since then. Yet the monsters still struggle to find their place within the world. Most accept the monsters, but there are those who wish nothing more than the complete annihilation of monster kind. Merely sealing them away is not enough. As ambassador for the monsters, it is Frisk's responsibility to fight for everyone's right to live on the surface. But at the same time, an internal battle rages on within her. Not only that, her relationship with Sans is strained. Trust is not so easily regained after the slaughter of one's beloved, despite it all being erased. Or was it really? The memories are still there. *I have lost interest to complete pre story and post story parts. Please enjoy the main story and the extra tidbits.* Chinese Version: http://fav.me/db7h2kg DISCLAIMER: I do not own Undertale. TobyFox is the creator and owner. Cover art does not belong to me. I only edited it. Photo was found off Pinterest. If anyone knows the original artist, please let me know! I'd like to give them credit.

Saving Them (an Undertale fanfiction) by fucking_username

The barrier is broken, monsters and humans are living in peace, everyone is happy except for one person. Frisk has been getting waking nightmares about not saving Asriel. They want to save him to erase all guilt and to be with their friend. But Asriel isn't the only one that needs to be saved. Something, someone lurks inside Frisk's soul. Someone deadly and has a hunger for power, and can kill anyone they want. A/N Frisk and Chara are both gender ambiguous in this story. Also there will be a little bit of Frisk x Asriel in this story, but this is not a Frisk x Asriel fanfiction. Credit to @karinacat59 for the cover. Undertale belongs to Toby Fox and none of the characters are mine.

Underopian by GloomStudios

An Undertale AU with the setting being a dystopian city. You follow Frisk on their journey through the dangerous Underground, meeting friends and foes. Frisk also meet a mysterious character that follows and helps them throughout the Underground, although, it seems they may have strange intentions in the end. There are drug and alcohol use included as well as strong language which is why it's marked as mature. It's finally finished! I started this at the beginning of January and I got it done! I'm really happy with how it turned out and I hope you all like it too! This is the first story I'm writing so I'm not expecting a lot from it but I hope who ever finds it enjoys it! I'm also planning on making other stories from this. This will be the main canon story, but I am also planning on making an epilogue story of the Genocide route. It will be named as canon as well of what I have in mind right now, but things may change, who knows, see what happens when we get to it! Also huge thanks to everyone who read part of my story!

Soulless (Undertale FanFiction) by BanthaBug

In the world of Undertale, it's supposed to be killed or be killed. This means for many, you have to fight if you're gonna survive. But in a world of fighting on a spiritual plane, how do you fight without a soul? The rumor of red-heads having no soul was nothing but a rumor until the girl was born. Still able to feel the basics of emotion, but without fear or love how will she fair, in the underground? *I have not edited this. I mostly write from 10pm-2am so in unedited parts it may get a bit confusing. Once it's laid out I'll go back and do the editing. Also know that I write approximately 20 pages an update. So if you're not into the longer reader turn back now* *I DON'T OWN ANY OF UNDERTALE!!!! NO CHARACTERS NO NUTTIN! ONLY THE MAIN CHARACTER AND PLOT IS MINE ONLY!!*

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.

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!!

Another Tale by Indian024

what if Asgore and Toriel part on good terms after his delcaration of war? what if Flowey did not turn evil by the time Frisk came into the underground ? what if Papyrus was more willing to fight and more able to dodge (..without still knowing what capturing a human would do)? what if Sans still did not find about "the anomoly" due to Flowey's lesser amounts of resets? and more small things a "what if" type of story for all to see
