Inktober but it's written stuffs
It's a little thing of written stuff about Undertale and it's aus. Some for a day might be short and others might be longer. It'll have angst and fluff or just complete chaos. It'll also switch from human to skeleton, just a heads up there. Also the prompts are made up by me so..yeah. Anyway, hope y'all enjoy this!Complete
Wait... I'm Nightmare!? I Thought I Died!?
(Cover made by me!) (!Updates 1-4 times a month¡) You died by cracking your skull open as you walked out of the shower. Godamnit life!!! To die in the most idiotic way!!! Which was very frustrating until you met a strange entity in the 'in between' that causes you to be reincarnated as Nightmare. Errr... sorta. What happens is that your soul merges with Passive!Nightmare and Corrupted!Nightmare, so they are now your buddies for life but in ghost form. God... kill you now (again), you never knew you were going to sign up for this when you died. ~Started Jan 19st, 2022~ ~Completed May 10th, 2023~ Highest rankings 🏅 #1- Dreamtale out of 1,000+ stories 4/19/22 🏅 #1- Dreamsans out of 1,000+ stories 5/12/22 🏅 #1- Nightmaresans out of 1,000+ stories 5/29/22🏅 #5- Comedy-drama out of 1,000+ stories 9/30/22 #1- Fandom out of 1,000+ stories 10/10/22🏅 #1- Aus out of 1,000+ stories 9/24/22 🏅 #1- Undertaleau out of 1,000+ stories 10/10/22🏅 #1- Reincarnated out of 1,000+ stories 9/30/22 🏅 #2- Guardians out of 1,000+ stories 1/26/25 THANK YOU SOOOO MUCH!!!Complete

Again this is just for fun and nothing is really planned just improv to be honest. Still hope you enjoy! The cover was made by meComplete
Given An Unwanted Second Chance
(TW: unaliving thoughts and memories at the beginning. It gets better over time, don't worry! Trauma is difficult to overcome...) You didn't want a second chance. You didn't want to survive. You wanted the sweet release of death. But it seemed like the universe was far too cruel to allow you even that. It took away your memories, your free will to choose whether you live or die...hell, it took the one thing in life you owned! Your own name! And now it seemed like you had to live yet another cruel life, doing things you never wanted done to others. But...at least you could do things your way. Maybe this second chance wouldn't be so bad... (Reincarnated as Nightmare Sans, but unlike other stories, you have no clue what Undertale even is) (WE REACHED NUMBER 1 IN THE UNDERTALE TAG YOOOOOOOO) (9/13/25)Complete

The Silent Destroyer
cover art isn't mine and belongs to its rightful owner Error is finally ready to give in. The multiverse he spent so many eons protecting and keeping the balance is rebelling against him. The AUs he has spent so long protecting are rebelling and are soon to be destroyed, but worst of all, all of the Sanses hate him for some reason. And I mean ALL. Why should he continue? There's nothing to live for anymore. Not even his family can help with this. Or, the people he thought to be his family.
Soul Fused
Nightmare, who has been dead for the last century, stumbles across a dying Sans in a destroyed au and takes him under his wing. Er, tentacles. From there, they start a band of rejects to get revenge on his brother. Sadly, said brother has other plans for them. That wont stop the shakily made team from bonding and having fun though! (AU where Killer is the leader of the 'Bad Sanses'. I own pretty much none of the characters)Complete
