(Y/N) and Sans have been best friends for who knows how long. Nothing could ever ruin their friendship... or could there be something? The human and monster war breaks out and the monsters are trapped underground, making Sans and (Y/N)'s friendship come apart. Years later, (Y/N) decides to hike up Mt. Ebott, where the monsters got trapped under, and falls down a hole. They end up seeing everyone they remember from when they were younger, but will THEY remember (Y/N). If they do, will they even protect her from the evil in the Underground, or will they let her die?

(Y/N)'s parents abuse her since she was the mistake in the family. MONSTERS has been released from the underground by Frisk. Frisk And (Y/N) go to the same college (Frisk is older in this). Little does (Y/N) know , she met someone who who cares for her. What will (Y/N) do??

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.)

The monsters have been released from the Underground, and are planning on making peace with the humans. Frisk promises to be the ambassador of the Underground residents, and as the years go by, the humans and monsters slowly become friends again. Frisk continues to be the ambassador for the monsters, learning more about her friends and herself as she gets older. Sans has had feelings for her for awhile, and he's been afraid to confess them to her. But he'll have to soon, because while Frisk grows older, gets married, has children, and lives her life, he stays young. I'm usually not one for writing fanfictions, but after playing the game, I couldn't help but ship these two characters. And a friend of mine asked/dared me to do it. Note: Cover is not mine, and belongs to lacampanellanuraver on DeviantArt IS COMPLETE!

After Ethan (Frisk's older brother) broke the barrier and set everyone free, they went on a huge trip around the world to spend more time together. Frisk had no time at all to talk to her friends and to top it all off she had lost her phone on the first plane ride. Her and Ethan decide it's a good idea to go back to where all of her friends live after over a year of traveling. Frisk was so excited to see her friends again. Especially Sans. Before she left they shared their first kiss and she said that they could work out a long distance relationship but it didn't work out since she had no way of talking to him. She just hopes that they can become closer after not seeing him for what felt like forever. Most of this story will be in Frisk's POV but I might change it around sometimes. Frisk and Sans are about the same age and Frisk is a girl. Chara will be in this sometimes but she's not a genocidal maniac. Also Asriel is in this as well and Flowey was never a thing. One more thing. This will have some curses in it so if you don't like that, don't read it. Anyways, enjoy!

Monsters are finally free to roam above the underground! After splitting up with Papyrus, Sans starts to feel a bit bonely. That is... Until he meets (y/n) (y/l/n). Then his world flips upside-down. But when people start to become scared of monsters, will this romance be able to last? Or are monsters and humans destined to never be together? *** Hello. Welcome to my newest story (I say that a lot...) which I'm really excited to write for. Please do not post hateful comments in this story, as I always try to keep a positive atmosphere in all of my stories. But helpful criticism is always taken and appreciated. Can't wait to see what all of you think! =^-^= *** Ranked 326 in 'sans x reader' as of 5/9/2018.

"I couldn't hold my breath for so long, my vision was all blurry, and my hearing muffled. I heard a loud splash and saw something red and flowing. I felt something pulling me out and a sharp pain on my right ankle. It felt like a cut to me. I could barely focus on the pain since I was losing consciousness. Everything slowly went black as I heard a familiar voice calling out my name." Alphys and Undyne are strangers to each other. After sorting out Mettaton's problem, they get stuck in a dorm together. It may take a few months for them to bond, but a school dance and summer break can really bring them close. So will they? Will they be together in the end?

Finally. They made it to the surface. But after an attack on the monster king, Undyne reveals a hidden secret that destroys the group. Can they bring themselves back together, or will their friendship break even more. (I suck at writing descriptions [~_~] )
