Crossmare Valentine Special by BubblyShip

(I do not own Undertale or the AUs, I just own this story!) Cross never did believe he would receive love. Nightmare never thought he would find love. Maybe they both were wrong, on a number of things. And just maybe, they can share an apple together at last.

Fallen (ErrorInk) by stillmirus

I dunno wut im doing, sorry if its bad ;~; Some Background: Most alternate sanses are attending a highschool, call the school whatever you like. This takes place in an AU thats not really an AU, seeing as there are no undertale characters. There is a "Gang" in this school, it is comprised of Nightmare, Error, Cross, Killer, Horror, and Dust. Everyone is afraid of them, except for the Star Sanses. Eventually, one of the star sanses, Ink, is able to befriend one of the bad guys, Error. Error starts to develop feelings for the artist, but, when something bad happens to Ink, error wonders if he'll ever get a chance. {This is an extremely slow-burn! You have been warned.}

Hope yall enjoy my suffering :D (Original story by Jakei - Transcribed by isimpforanimeboys1) Hey! You've reached the bottom. Quick note, the editing in this is quite bad. I wrote this in 6th grade, and I'm not very proud of it. There are multiple mistakes, such as me calling Underswap!Chara Frisk, and referring to X!Chara as they/them. PLEASE DON'T PAY ATTENTION TO THESE MISTAKES. THANKS FOR READING THIS.

Ghost Stories (A Sanscest Story) by carelesscreativity

Nightmare, go to school, they said. Nightmare, it will be FUN, they said. What a load of crap. Nightmare isn't buying any of it. His brother's loved and he is feared. When invited to go on an outing while weakened that leads to some supernatural involvement, Nightmare meets someone that will change his life. The problem? For better or for worse? That's a joke. His life can't possibly get any worse. Ships: Crossmare Errink Kreme Dustberry Afterdeath Horrorlust

Another Chance (Reborn as a Sans From Naturetale) by ZenInPeace

"Please just... leave me alone..." Maybe that was the last straw for me, the last beating I could take before it finally kicked me off the edge. The last of anything I could handle. I've had enough of this. There was nothing I could want, nothing I held on to, no one to stop me for what I will do. So, why do my 'eyes' still open to a ceiling, rather an unfamiliar one? --------------------------------------------------------------------------------------------------------------------- Warning: Suicide, self-harm, rough language, etc. If these topics are sensitive for you, please read at your discretion. --------------------------------------------------------------------------------------------------------------------- Wholesomeness inspired by: @DeadEnDead Using Naturetale as the base character inspired by: @KarmaAkabane425 --------------------------------------------------------------------------------------------------------------------- Obviously, Undertale and the AUs do not belong to me neither do any music or pictures that may be used. The only thing I'd claim is the changes in design of the OC I've created. Basically my version of the Sans from Naturetale. I have decided to name this AU Barrentale due to the undergrowth dying out and the majority of the monsters being related to more fibrous or woody plants.
