What Went Wrong? by AngelOfTheDead80

~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~

Flowey x Reader: Teach Me how to Feel by xXGalaxieXx

"I told you, can't feel right!" The feeling you get when you're on a roller coaster jolted your stomach as you fell from the edge of the cliff... you hit the ground... and everything went dark. That's the first thing you remembered when you woke up in that honey-scented patch of flowers. "There's no sunlight down here." There's no sky. There's no birds singing in the morning. Everything was different in this new world that you had fallen into, and you were determined to get back to your world. Until someone decides to help you. Now you were determined to get both of you to the surface. Nothing could stop that. "Right...?"

Colors | Chara x Papyrus by NoellaBerry

~~~ [COMPLETE] After being set free from Frisk, Chara finds herself shoved into a new life that she didn't ask for. She's cold and distant for days, void of a SOUL and seemingly proper emotions. However, there's a certain somebone who refuses to tolerate it anymore. Unlike her, he's kind and unfortunately, always around. When Chara finds herself dealing with unrecognizable feelings, he knows just how to help her. ~~~

Most Powerful Monster by thundersnake2375

I'm writing a fanfic on the popular game, Undertale. You fell down into the Underground at the age of 11, but little do they know that you had secret powers, at least until you got carried away. None of the pictures or videos belong to me.

Undertale - Fighting To Stay [Frans] [Book 3] by SepticGirl88

So, monsters and humans have been living together on the surface for quite a few years now... That's an accomplishment! No resets, no new timeline. Just a future continuing forward like everyone could have possibly hoped for. However, not everything is hopeful. You can't expect to live a life where everything is sunshine and rainbows. Even with no longer having the threat of someone like Chara, things can still happen when you least expect them to. You can't always have your "Happy Ending".

Undertale X Reader [In Remake] by Cat_Maipie

Let's get to the point shall we? So let's look at the list here... You're a... no information? Hm, interesting i guess, I'll have to base it off my observation. Whatever, you're a human, well kind of. You're a human and a monster at the same time, more like in between. Let's say... player? Better than nothing i guess. You're your own person. Sometimes you control frisk, sometimes you don't. You can also move through timelines, and also universes but that may be too risky huh? You'll find more about it soon... THIS CONTAINS VIOLENCE PLEASE BE WARNED! Lemons? Maybe. - #57 in sans 12/14/25 - #1 in floweyxreader 01/10/25 *** COVER : Credits to the person who made it GAME : Toby Fox

A Strange Feeling (Sans X Reader) by Sak423

Do not expect consistent updates as life gets busy 🙃. This is rated mature because of strong language. You are a 24 year-old in college and have loved Undertale since the beginning. You enjoy all the aspects of the game; the story, the lore, the music, the backgrounds, and most importantly the characters. You've started having a strange, almost malicious feeling related to the Genocide run and that creeps you out. So, you start a pacifist run and after a while, you fall asleep. You wake up in Undertale and thus begin your new journey. Through your travels, the strange feeling comes back, but as a different emotion. Perhaps the only one that can help you with this feeling, is a certain punny skeleton. (I tried my best I'm not very good at summaries 🥲.) (Also I am so sorry for the kinda weird writing this is my first time writing a story. So I welcome constructive criticism.) Started: January 26, 2025 Ended: ???

Reset (Sans x Older!Frisk) by error-code-707

There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

The First Human [X Sans] {COMPLETE} by RaeTheStar

Imagine Undertale, but Chara never showed up. Chara wasn't the first human in the Underground. What if a glitch occurred, and you fell down instead? You fell into the Underground, but you cant remember your previous life. Now, you are surrounded by strange monsters, who have also never seen a human before. Will they let you live? [written 2017]

Dual Stones - Undertale Fanfiction (COMPLETED) by IcyDuelist

Duska has something most people would call a traumatizing childhood which she only escaped from a few months ago. Now she finds herself beneath the very mountain she was born in with monsters around every corner. She decides to start her life again here, in the house with Papyrus and Sans, but monsters don't live the most ordinary of lives either. Duska's past is catching up with her but the wall of friends in front of her may be hit by the impact first. No pictures, videos or any other media belong to me unless specifically said. Will have some swearing in it. Undertale belongs to Toby Fox. Thank you for creating such a beautiful game! I FINALLY FINISHED IT!!!

Wilted [ Sans x Flowerfell! Reader ] by morrow-

You were afraid. For the first time in your life, you were truly afraid. You weren't afraid of the never-ending darkness that had now consumed you. You weren't afraid of the monsters underneath your bed. You were afraid of the flowers.

Where do u think u're goin'? Yandere! Undertale Characters x AnyGender! Reader by Pandy999

The story takes place after Frisk sets free all the monsters in the Underground. After that, everyone was happy until...something horrible happened...

The New Life Of Duska Rose: An Undertale Fanfic - (UNCOMPLETED XP) by IcyDuelist

Many years ago there was a war between humans and monsters. Although monsters had inborn magic on their side they were sentenced to live in the Underground, seperated from the surface by a barrier of human souls. The monsters have broken through the barrier and now wish to live among us. Duska watches from her room as a reporter interviews King Asgore on the TV, wondering how life will change for her. Now she lives with two monsters. How much will her life change? Can she reveal her deepest secret to them? Will she find more about herself? Will she fall in love? (Undertale does not belong to me, only Duska does. The songs linked belong to their respectful owners and so does the art. There will be swearing and strong themes. Please enjoy!) (Will upload a new chapter every Australian Tuesday and Thursday.)

•❤• Leaving a place that gave you warmth, you struggled to went across the snowy fields only to meet thousands and different monsters. As surprising as it sound, you, a fellow human, felt really close to them. They were misunderstood. By your kind. It wasn't even your fault yet why do you pity them? You roam around the Underground carrying a name. A name that you believed was yours. A name that your mind had buried into your SOUL. Yet . . . why does it feel wrong? Like . . . it wasn't yours at all? •❤• Sup? This is my first ever fan fiction! Hope you like it, enjoy and yeah. See ya.

Sunrise by ArinBlackheart

*WARNING* Undertale spoilers!!!! I'm trying to keep in character as much as possible, but I'm human and they will be a little off at some point or another. It's supposed to be innocent, so things won't get too deep in terms of romance. No, there's no Papyton or Sansriel. The only pairing is the canon Alphdyne and Asriel (asgore/toriel[I have hope])

Undertale: Genocide by CassBunnys

"In this world, its kill or be killed" - Long ago, two races ruled over Earth: HUMANS and MONSTERS. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell. After the war, the monsters retreated into the deepest part of the Underground, which would be called, "Home." - Note: In chapter one i NICKNAME frisk "Sam" Due to the fact you dont figure out their name until the end of pacifist so i had to put a nickname to make it easier to write and read. Sam is a neutral name so it should be fine. - NOTE: All lines with this symbol " * " is going to be in Wing Ding font in the final release of the book. But for now, it is already deciphered for you! - *So yeah! This is book one of my Undertale Series, which will be 2 books in total. *The book is Fanmade of course, Support the original game by Toby Fox. *Since its Undertale, i have to warn you guys obviously that there will be action and mature things. And book one is Genocide, so... *Follow my Instagram: @Djcasso -

Forbidden Love ( Frisk x Sans) by Nashi012704

Hi guys this is a new story based off of the game undertale. Also this is my first fanfic I have ever written so I hope you like it. Frisk is 13 and so is chara. Sans is 130 which basically means he's 13 in monster years. Papyrus is 160 and toriel is 170 aka 17. Undyne is also 170. Mettaton is a girl. Alphys is 160.

A Different Kind of End - Book One - Reset by Toasty-Writer

Hatred is like an infection, if left to fester it only spreads and becomes worse, until there is little to no hope of return. Frisk had abandoned her life on the surface, she had no expected to survive the fall, even less so make friends with the monsters rumoured to live under the mountain. So what happens when she leaves and is all alone once again... What happens if she listens to the flowers advice..... Book one of A different kind of end. I do not own Undertale, or the characters used, simply the story concept.

Betrayal of Euphoria «Book 1» by xHaunting-Whispersx

"I'm bleeding...but it seems as if my fears have vanished as I stare at the male before me. He gazes at me with such intensity and I can't help but feel...compelled by his alluring crimson eyes. A feeling of felicity bubbled within my stomach. It was weird...since this man kidnaped me and all, but...I wasn't afraid-not a sense of qualm within my body. I was relaxed and eased...I wasn't afraid, which I guess, made me enjoy his presence. He was a God and I was the measly beggar before him...Oh, how I just wanted him to hold me...wait...what am I saying? "'Snap out of it Blu! He kidnaped you! This isn't some Stockholm Syndrome thriller! He's going to kill you if you don't do something!!'" Despite the edge my conscious clearly announced, I felt at peace. I was happy-no anxiety, no sadness...just bliss...he treated me well and I loved him...but, did he feel the same?" - This is kind of like an AU? Like Chara is an actual human not a video game character, along with Frisk who pops in or is mentioned a few times throughout the story. This story contains smut (it's shitty regardless, lol) and swearing, maybe, and it's between two males. If you're not into gay stuff, then this story is not the right one for you. :) It's also written in third person, not first person, like the description is...oops? Disclaimer: I do not own Chara or Frisk, I just own the plot and the character Blu, his family, and that's about it...
