Reset (Sans x Older!Frisk) by error-code-707
18 parts Complete
There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

Undertale AU by me. I don't own any of these characters besides Zombie and Wisp. Degree belongs to my homeslice. I really hope you enjoy it and make it a little more official. It'd mean a lot if you voted too.

Undertale:Secrets by ItIsComic
34 parts Complete
Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book! Cover art by someone? I couldn't find the original owner :( Undertale by Toby Fox
The Demon Inside of Me (Grillby X Reader) by bananahfart
45 parts Complete
A long time ago, monsters and humans lived peacefully. Then, war broke out. The monsters were forced underground, and the humans were left above. A killing machine was created, to destroy all the monsters in the underground. This is her story. Asgore is the prince, who lives in the palace with his father (Nazur) - who is on the edge of death - and his wife (Toriel) and son, Asriel. Toriel and Asgore are about 20. Gaster and Grillby are buddies around 19. Sans and Papyrus have no set age, they're experiments. If they did, they would be 17 or 18. Reader-chan is 18.

I never meant to fall in love. I never meant to have children. I never meant to become involved in a war. I never meant to lose people I love. I never meant to let us be thrown down here. I never meant to become the royal scientist. I never meant to do lots of things in life. But I always meant to live.
