3 YEARS AFTER THE PACIFIST RUN OF UNDERTALE:
The monsters, along with their Ambassador, Frisk Dreemurr, are living in peace on the surface. 
Toriel runs a school made for both monsters and humans.
Asgore works at a botanical garden in Ebott City along with his now non plant son, Asriel.
Mettaton is a successful TV-Star and show host.
Papyrus is a well renown chef and five-star food critic.
Alphys is the head of the science faction of the city, and is working on how to cure determination poisoning to help the amalgamates.
Undyne is a highly known police chief and gym instructor.
Frisk is living with Toriel, and has a peaceful life, give or take a few governmental and presidential meetings, plus having Chara to deal with.
And Sans...well, he's Sans. What did you expect?
Everything seems happy.
But.....
Frisk has been getting the nagging feeling something is a little off. Sans is less happy than usual, and he's being secretive. Every time they asked, Sans just replied with a grin and a few puns. What is he hiding? And what is this nagging feeling that they forgot one more person to save?

(Hey guys! This is the first UT book I'll do without using my OC's! But, the thing is, this shall be your book as well! It's a choose your own adventure kind of thing! Tell me how you like it, and when something happens, vote on one of each options!)

(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

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
