It was just a peaceful day in Snowdin. Everyone was just doing what they normally do in the underground.

The Nicecream guy kept selling, monster kid was playing around, Grillby was cleaning up some spilled ketchup. Even in the Skeleton household, Sans was chillin in his room while Papyrus was working on his spaghetti. 

But not everything is what it seems

Suddenly, a loud thump was heard outside of the brothers house...

Stuck Together(Errink) by The_Bi_Marshmallow

(This is the first book I've ever written so the start is probably sucky and has spelling mistakes) I haven't updated this in like a year, planning on rereading this and seeing where tf I might've been taking this. ⚠Needs editing⚠ Error and Ink may be enemy's, and polar opposites, but they are both more alike than they think. After being attacked by an unidentified enemy, both Ink and Error are both badly injured. Once the enemy disappears without a trace, neither Ink nor error can seem to teleport or create a portal out of the anti-void. They now have to work together and find get help in order to get out. From both sides in and out of the anti void everyone must help and research to get ink and error out. Will they find a way out? If so, what happens once they do? Will a truce become permanent? I remember people saying that Blueberry and Swap aren't the same person. But they're actually two different versions of the same character from Swaptale. So initially interpret my Swap sans as whichever design as you want. But the personality is supposed to be of swaps design. I'm just calling him blue. !! TW, this does include the gay and ErrorInk so this might not be for u. This will also includes mild course languages from time to time!! Ships: Errink (Error x Ink) Crossmare (Cross x Nightmare) MAYBE???? (There may be more added on later in the story)

I want Her (Underswap!Sans x Shy!Reader) by GamerQueen2002

Yandere!Underswap!Sans x Shy!Reader And some Papyrus x reader -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- He was so sweet, so innocent. All he loved doing was cooking tacos, listen to his brothers puns, and try to be friends with everyone. Then you're pushed down a hole and end up in this strange new underground. After seeing you, his sanity breaks. Instead of making tacos, he loves hearing bones pop. Instead of listening to his brothers jokes, he bathes in blood. Instead of making friends with everyone, he kills them. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- "You can't escape. Not now. Not ever." -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Sequel to ending D: Silently Sleeping (Underswap!Papyrus x reader) Sequel 2: A New Life A/N edit: Apparently, I like this word cute. Oh, and, under a bunch of editing. A/N edit two: OH YEAH, and very cliche! XD

Don't Forget [Sans x Female Reader] by GabrielXander

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

Hungry Love (Horror Sans x Reader ) by YandereEmo

In the midst of Tokyo's bustling streets, you led a life that appeared ordinary, despite your role as a leader in a prominent gang. Yet, beneath the façade of normalcy, you carried the weight of profound loss-your mother, your father, your brother-all taken from you, leaving behind a void that seemed impossible to fill. Determined to shield yourself from further heartache, you resolved to protect the one remaining person you held dear: Frisk. Their presence brought light into your shadowed existence, offering a glimmer of hope amidst the darkness of your past. But fate had other plans. The dissolution of your gang shattered the fragile stability you had built, leaving you adrift in a world that suddenly seemed hostile and unfamiliar. Yet, in the aftermath of this upheaval, you found solace in Frisk's unwavering companionship, their presence a beacon of comfort in a sea of uncertainty. Then, in a cruel twist of fate, you lost Frisk. Cast into the unfathomable depths of the underground, your path collided with Aliza's, a chance encounter marked by the ominous presence of Horror Sans. Emerging from the shadows, his hollow eye sockets bore into your soul, his grin sending shivers down your spine-a chilling reminder of the darkness that lurked within the depths of the unknown. With each loss, the world seemed to grow colder, more indifferent to your struggles. Yet, amidst the despair and desolation, a glimmer of resilience flickered within you, a quiet determination to reclaim what had been taken from you, no matter the cost.

Lost Cause by AlexBrant18

Remake since I am not much for the other one, but that doesn't mean I'm gonna forget about it. I didn't post the first one cause I thought it might be bad. If you want me to post it just ask! So anyways... Error had gotten sick of it all, he lost all of his anger for it and during a fight got a giant crack and set a portal to the Void where he died and was reborn as a child and sadly lost his memory. But when he's found things that seemed bad in ones eyes is good in his eyes. -2021 edit- -Grammar errors being fixed -I noticed a hand full of readers are lost or confused about Underswap Sans' and Undertale Sans' nicknames. Underswap Sans- Blueberry Undertale Sans- Blue I am fixing it since I have the free time. Happy reading!
