Long before Frisk ever fell down to the underground...
Before Gaster got lost within the Core...
He found something... or rather someone of great value to him
...someone he would protect with his life...
...someone he would grow to love...
until it was up to Sans to protect her...

To Hell and Back (Gaster x Reader) by xsfolia

"What's that look for? Are you perhaps unhappy to see me?" "Oh no. Oh no, quite the contrary, my love. I've craved to be with you for the longest time" ***** You were sure that you would have captured a Monster, at all costs. But were you sure that you would have captured not a Monster's body, but a Monster's heart? ***** The Barrier is broken • Frisk has saved the Monsters • But not all things went according to plan . . . . ...... It is renowned that Frisk fell into the Underground. They spared everyone, they had [Mercy] for everyone. In the end, they have chosen to be an ambassador for monsters, to represent them in front of all the other humans. Frisk was full of [Mercy]. But the humans weren't as merciful as them. Humans completely forgot about Monsters, and now they had to deal with what they considered an ancient enemy, despite the Monsters' friendly intentions. What will Monsters do, if they suddenly are persecuted by Humans? Will they seek help? Will they search for old friends? ... Was it reality? Or was it a true living Hell? Things always went according to plan, so why? This time, why did it have to end like this? You are a spy, working for the most powerful secret Organisation of the Human Government. Your job is to find your targets and bring them back at the Organisation, but if you have the order to, then you have to kill them. This time however...you underestimated the enemy. ***** The new plan was quite simple: bringing him back in exchange for your freedom. Falling in love with him was not part of the deal though. ********* Word count: 110.473 Cover by Earth Garden on tumblr!!

I'm a Sans ( au sans x reader x au papyrus ) by KittycatTDH

This isn't a typical sans x reader(now papyrus x reader too). It's got more than that, well at least a different plot device first chapters will be about, just you(but it'll be good, I think so)and it's about you dear reader, you are now reborn as a Sans of a different au, but you don't have time to marvel how you're been reborn as your favorite character, because if you want to live you better focus because unlike frisk you're not coming back a second time when you die. (Short, and I mean short chapter, but this will ensure I can post more -w-) (Edit: this is context of your previous life is that you are originally female, aged 15, you had died during a car accident, you were sleeping in the back of the car, while you had a road trip to visit your family in Canada. The car had driven off the road because of black ice your father did not see in the dark of night. You heard the sound of your fathers scream then lead by your mothers then little brother's scream. You banged your head in the chair in front of you making you pass out, and when you open your eyes you had found yourself be popped out, but you didn't know that at the time. Art always be done by me. Edit: discontinued

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}

The Bad Time Hero (Male Reader x MHA) by MegaMess21

Willpower (an Undertale fanfic.) by Quacker_Zach

In the undertale universe a human fell down into the underground (AKA the monsters' home) this human is known as Frisk. She (Canonically she is gender neutral but for the sake of the fanfic they will be known as a she) befriended the entire underground by freeing them from a seemingly eternal spell that trapped them down there for many years. Though to get there Frisk had to sacrifice a friend (Asriel) and from that day on frisk just couldn't get the fact that she couldn't save someone out of her head. And she will soon find out that she'll have to sacrifice a lot more.

Saving Them (an Undertale fanfiction) by fucking_username

The barrier is broken, monsters and humans are living in peace, everyone is happy except for one person. Frisk has been getting waking nightmares about not saving Asriel. They want to save him to erase all guilt and to be with their friend. But Asriel isn't the only one that needs to be saved. Something, someone lurks inside Frisk's soul. Someone deadly and has a hunger for power, and can kill anyone they want. A/N Frisk and Chara are both gender ambiguous in this story. Also there will be a little bit of Frisk x Asriel in this story, but this is not a Frisk x Asriel fanfiction. Credit to @karinacat59 for the cover. Undertale belongs to Toby Fox and none of the characters are mine.
