Deltarune Scenarios (+Oneshots) by RoryTheVoidWriter

Seriously though. I'm just joining the bandwagon. Feel free to jump in for a ride. (A/N: A super, SUPER duper old dump of headcanons I wrote waaay back when I was DT-obsessed. I didn't have the heart to delete it, so I'm keeping it public, for old times' sake.)

Undertale : Secrets (REMASTERED) by ItIsComic

Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that, despite being so long ago, always finds a way to bite back. A past that defines who he is - but he longs to erase. A past that doesn't let go, it clings to him despite his endless attempts to escape. And when someone finally attempts to uncover the veil, and fails in the process, what happens next? This book is a complete remake of the original Undertale: Secrets that was made nearly 3 years ago. By remake, I mean that this book takes the general plot of Secrets and basically "tries again". This will reuse elements of the original and cut out the parts I don't like while adding my own new ideas, effectively creating a new book. Whether you liked the original or didn't even read it, I hope you like this!!

Protect One Another - US!Papyrus x Reader by robin-rights

Trauma is a powerful thing, and not something to be taken lightly. Especially if your "best friend" is the cause of it. But friendship, understanding, and love, are also powerful things. They can save someone from the depths of despair. And those people that pull us from terror are often the ones we fall in love with. Platonically... and sometimes, romantically. *** Undertale and all original characters belong to Toby Fox, Underswap and its characters belong to Popcorn Pr1nce (inactive tumblr now). Date Started: March 7,2021 Date Ended: June 12, 2021 Impressive Rankings: #717 in undertale (of 48.3k stories) #3 in undertaleau (of 5.1k stories) !!WARNING!! VIOLENCE, SUGGESTIVE HUMOR, MENTIONS OF "ALCOHOL," SUPER BAD AND OLD WRITING Cover done by me, art isn't mine though. No art in this book belongs to me - credit goes to amazing artists who put in their effort to make amazing stuff for us.

A Destiny's Promise (UT Sans X Frisk) by LJadeite

*COMPLETED* DISCLAMER: Cringe warning. This is my first book I have ever written so please bear with the grammar and spelling issues inside. DO NOT READ IF YOU DON'T KNOW UNDERTALE. Life isn't that easy like we've always thought off. Everything changes as days went by. And that's a fact. After the years, Frisk started to fall for a certain skeleton, which has the same mutual feelings as her. But what they didn't know is that they are putting everyone they love in grave danger... HOPE YOU ENJOY THE STORY!!! (Undertale and its respective characters belongs to Toby Fox. Story plot and OC's made by me) Started on: 10/16/17 Ended on: 8/11/18

UNDERVERSE by isimpforanimeboys1

!THIS BOOK WILL NOT BE UPDATED!FOR FULL STORY, CHECK OUT JAKEI ON YOUTUBE AND PATREON! The story takes place in a post-Pacifist timeline in the original universe of Undertale, where half of Sans' soul is stolen by a corrupted alternate version of himself known as Cross, who has his Chara inside his body. With the help of Ink -the guardian of the AUs- Sans will travel through the Alternate Universes to recover his soul while he discovers the origin of Cross and the imminent danger that will put the Multiverse at risk: The Overwrite button. Undertale - Toby Fox XTale - Jakei Inktale/Ink - Comyet/Myebi Error - Crayon Queen Fresh - Crayon Queen Aftertale/Geno - Crayon Queen Dreamtale/Dream/Nightmare - Joku Underfell - AU Community (The creator wishes to remain anonymous) Underswap - AU Community (The creator wishes to remain anonymous) Outertale - 2mi127 Core! Frisk - Dokudoki Undernovela - Pig-Demon Killer! Sans - Rahafwabas Fatal! Error - Xedramon Mild Swear and Violence Warning. 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.
