Into The Game >> (Sans X Reader) Undertale FanFiction by Melody4164

It was just a normal Saturday. (Y/N) was playing Undertale for the millionth time. She was obsessed. (Y/N) had played all of the routes. True Pacifist, No Mercy/Genocide, Neutral. She experimented with killing certain characters doing different things. Then, as (Y/N) started a new game, she felt a falling sensation, as if she just fell out of her chair. She blacked out soon after. When she woke up, she was lying on a bed of golden flowers. She knew this place. (Y/N) was in the game. She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself. I do not own the cover or any of the pictures that will show up in this book• *If you're reading this as a guy please just change the pronouns to he/him/his. I find if a lot easier to just put female pronouns. Thanks! :3 *

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.

Undertale:extended genocide (discontinued) by Anexistingperson

Undertale AU about sans escaping to the surface on the 100th genocide run.

Like the Dead by Missevilhat13

[1st playthrough Genocide] Sans moves in with Toriel after Frisk kills (almost) every monster. Soon after another human falls revealing an interesting secret.

Bloodfall (An Undertale AU) by BlackStormWolf

Ever since the death of his younger brother. Things have gone downhill in the surface world for Sans. Alphys died a few months after Papyrus to a disease, Mettaton and Undyne, especially Undyne, had fallen into a depression. Flowey dissapeared into mt. Ebott, not to be found and Sans is fighting depression and insanity. One day, Sans discovers a suspect to his brother's death. A being that is trapping anyone who had either fallen into Mt. Ebott or stayed behind in snowdin for a while. Sans, along with Frisk and Undyne, go into the underground themselves to confront this being. They must encounter the Bloodfall that traps and kills anyone who dares pass by waterfall. (This takes place after a true pacifist run if one killed Sans in a Genocide run, but reset their game before getting to Asgore(I did this in a way to quit the Genocide route). This is if Frisk choses to do this the Pacifist way. I might make a Genocide one in Story Shorts. Also, My Sans is a human, but feel free to interprate him as a Skeleton if you ever choose to use this AU. Just credit me!)

Disbelief by hmong7777

At the end of every genocide run, Frisk duels with Sans and wins. However, what if Sans begins to care once more and takes the blow in replacement of Papyrus? Who will lead the dance of fate with Frisk in the Judgement Hall?
