You climbed the famous Mt. Ebott to prove to a group of your friends that humans don't disappear when they go up the mountain. While walking around the peak, you trip over a root in the ground and fall forward, expecting to hit the ground. Instead, you were met with open air. As you fell down the large hole, you let out a shrill scream before hitting the ground and blacking out. 

When you wake up, you find yourself in the Underground where monsters had been banished to by the humans. 

You meet several monsters down in the Underground, some becoming friends and some becoming enemies. One particular monster though, has been making your heart flutter and your tongue get tied. 

Sans the skeleton. 

A new threat appears when a human that had been thought to be dead comes back and threatens you and the entire Underground. Will you be able to stop them or will you be used as a puppet and watch your friends die?

Maybe the only thing that can defeat LOVE is love...

Author's Note: this was my very first story so sorry if there's bad grammar or confusing scenes, enjoy my awful writing!

Chainsmoker [ Gaster!Sans x Reader ] by morrow-

Routine. The entirety of every living thing is dominated by it, human or monster. Everything HAS to be the same. It was in this that you were the exception. For you everything was new, every time line a detailed altered in order to satisfy your sadistic desire for a new ending, whether it be only a few details of dialogue altered or something else entirely. Monsters you once considered family you now butcher and slaughter without a second thought, after all, that's what the Reset is there for, right? And all at once it stops. Your small hold over the Underground is ripped away from you and you are thrown into a dying timeline, monsterkind's final attempt at self-preservation. You're alone, completely and utterly alone. Except one. And he has a bone to pick with you.

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.

My Anomaly (An Error Sans X Reader) by nightmare597

When your sibling Chara goes missing you fear the worst, but life takes a surprising turn for the better when they release the monsters trapped underground. Living this new life in your home AU of Underswap things couldn't be better. That is until a certain skeleton appears and threatens to tear apart your Au. Not wanting to loose Chara again or risk the loss of your new family you fear for the worst and attempt to strike a deal with this new monster. Your soul, in exchange for your entire Au to be spared. But what happens when this monster who steals you away can't take your soul in the end? What happens when he feels these new emotions he's never felt before? Confused and complicated emotions turn this situation into an even stranger one. And the more time seems to pass the more you realize, maybe he isn't so bad after all. But time is running short and it's up to you to find a way back to your Au before the timer runs out and you become like him. But can you do it in the end? (This is an Error X Female reader slow burn, I repeat slow burn. Cover art is my own! Some themes to this may be heavy to some readers so please proceed with caution! If you'd like this more gender neutral please let me know and I'll be happy to fix it! Enjoy!)
