(Has been rated #1 in Frans more than 10 times since April 2018) 
It's 210x, and nearly eleven years after Sans' " ignorant " deed. Little did anyone know it would be the year when the human has mysteriously fallen again, though the  seven human prophecy had supposedly been fulfilled. "Seven humans shall fall... Only one will enter and exit alive." 
By this time Frisk is a growing young lady and Sans is a young man, now working as head scientist for the royal family, along with Gaster and Alphys as his assistants. He is more than happy to see his old friend and she is welcomed with everyone's opened arms. That is...Until she is proven to be something a little more than she appears to be.... 
Join Frisk as she slowly uncovers the underground's forgotten past and her own dark side, hidden deep behind her DETERMINATION.


((This is an original AU by EkoingSkies. Warning! The main ship in this is Sans and Frisk! If you wanna read this, be sure to keep that in mind. This is my first book, so I would love to hear your interpretations of it!

(I DON'T OWN UNDERTALE. The only characters I own are Bailey and Creame.) All the monsters live happily in the underground: until one human ruins everything. Bailey Hill is a normal, 11 year old girl- until she trips, and falls into Mt.Ebott. Quick to befriend the monsters, Bailey is instantly loved by everyone. When monsters start mysteriously disappearing, Bailey is on the case. What she doesn't know, though, is that a small team, co-led by Undyne and Sans, are working as secret spies in the background. After hearing about the disappearances, Bailey thinks she can solve the mystery- but when Bailey has a shocking realization, she realizes that she might not be so innocent after all. ------------------------------------------- Changes: IMPORTANT: Frisk and Chara don't and never exist(ed) Monsters don't mind the underground, so Alphys never did the experiments. Still Relevant: Mettaton never left, and Napstablook is constantly being featured on his show The amalgamates don't exist since those monsters never fell down. Napstablook and Shyren are now younger than in-game, Napstablook - 12 and Shyren - 14. More on Napstablook- Since Mettaton never left, Napstablook is just shy. Everyone knows each other Alphys x Undyne- Already a couple Frisk and Chara don't and never exist(ed) ------------------------------------------- A note from Emma- Hi hoomans! I hope you enjoy this AU I came up with! Happy reading! 😊 10/4/2020: There IS a sequel coming soon! :D
Undertale; Despair AU 《REWRITE》 by LocalUndertaleAddict
27 parts Ongoing
What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How could a few measly children stand to this supposedly immortal foe and save the Underground from destruction? Is it even possible to do so? Only one way to tell... ~o0o~ Disclaimers before you start! •There is NO fanon ships. That means no Soriel, Papyton, etc. The only ships are Torgore (in the past) and Alphyne. •This is NOT an x reader. I heavily dislike those types of stories. The reader will have no part in this. •This exists outside of canon to an extreme. For example, Frisk is the second human and not the eighth. •There will be OCs, but only for a few humans and they still technically exist in normal Undertale. •There is a sequel. I'm planning on rewriting it after this one, as it is much more random and definitely needs it. Clanky, plot holes/retconning, etc. It's more of an OC thing, to explore them and their issues, than an Undertale thing, but it has its similarities. •There will be some explicitives. It won't be unnecessary or excessive, only when it fits the situation and character. I will not be using any slurs, as that's just plain disrespectful, even if some of them apply to me. Credits: Undertale, obviously, created by Toby Fox and Temmie Chang. "The Time Before" by ANinnyMouse42 is the backstory for Sans in this AU with some adjustments (mainly since that was very close to my original idea before I read it and I don't want people to think I copied their masterpiece or smth, if you haven't read it please do so, it's really good). Some things will be in reference to the other books in the trilogy or "From War to Science" by Emotistic-optimistic. If you haven't, read that too. It's really good (along with its sequel). The cover was made by me! Have a good day! (Also, the title is a placeholder, if anyone has any ideas that make more sense, please let me know. I do have some ideas, which are going to be mentioned at the A/N of C
AxeTale - The Untold Story by XxSilverShroudxX
12 parts Complete
NOTE - Both of my notes from my first AxeTale Story, "AxeTale - The Full Story" apply here, this is my own take on the AxeTale AU so there are some differences and the other being I am not big on the Frans part of AxeTale, but it is an important part of it, and they're both of age in this AU, so I will write it accordingly NOTE 2 - This is a prequel to my first AxeTale Book, so it will be connected to that one and lead into the events of The Full Story, you can either read this book first or second and still get the full picture Before The Story of Aliza... There was the story of Frisk... A human woman who fell underground and changed monsterkind forever... When the time came to break the barrier and save monsterkind from their confined prison... She couldn't do it... The only way to do it, was to sacrifice her own soul... And open the barrier that way... But Frisk couldn't bring herself to do it... She was too terrified of death... So she stayed underground with the monsters... With the death of the King to the malicious Flowey, the souls being locked away, Dr. Alphys trying her best to find an alternative way to break the barrier, and Queen Toriel returning to be in power... Frisk has a lot on her plate... Thankfully... She has people who will be beside her along the way... But this isn't just the story of Frisk.... This is the story of her lover... The monster she had dedicated her life to being with.... And how this all proved to become quite difficult for not just these two... But the entirety of monsterkind....

Determination - G!SansxFrisk

37 parts Complete Mature

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.
