Reborn as the guardian of positivity, you find yourself in a strange new world, uncertain of what it may hold. Navigating it isn't easy with gods like Nightmare and Error trying to strike you down every step of the way. But unlike the previous Dream, you have nothing to lose, and are determined to forge a better path than the soul whom you have replaced. Cover art by the wonderful @Nymara379 on A03 ♡

« ˡᵒᵛᵉ ᵘˢ ᵗᵒᵍᵉᵗʰᵉʳ ᵃⁿ ᵉᵃᵗᵉʳ ⁱ ⁿᵉᵉᵈ ʰᵉʳ » kris x female reader/krissoul HEADS UP‼️ Because this dynamic is already toxic by default (Kris and Player), this one will be too. There is probably NOT going to be a completely happy ending for you two. It's toxic okay? But, there is acceptance and learning to accept one another later on :p Some topics that may appear: Co-dependency, hatred, forced proximity, betrayal, thoughts of violence, abandonment, shame. maybe a few hugs and maybe a kiss, not anything more than that- and NO, there isn't smut. You're weird if you're looking for that. These are teenagers. on A03, same title, username: renoxeno on a03

#1 of 61.7k tagged with Undertale 12/06/24 After drowning as a human, Ashe reawakens as a DustTale variant of Sans. With his ghost Papy helping keep him from falling into suicide a second time, Ashe slowly learns he can have fun, and what's more fun than fucking with the Star Sanses who have totally mistaken him for the 'evil' Dust Sans?

(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!!!

PLEASE READ BEFORE GETTING INTO THE STORY. Your name is (Y/n), and you play the role of an unusual pacifist. In the story of Horrortale, your unique soul allows you to see WD Gaster who no longer holds a powerful connection with the underground due to the inactive core. After your parents are killed, Gaster makes a deal with you. He will help you extract revenge on your parent's murderer, and in return... you were going to fix the core in the underground. While Sans failed to do it when everyone went insane, you knew what you had to do because well. The creator of the core told you everything that you needed to know. The real trick isn't the resources that you've been gathering during your time on the surface for the job, it's the things that are in the underground that you have yet to obtain. While it is true that you have a lot of experience with fighting and a high amount of LV thanks to Gaster's guidance... you now decided to stop killing, and start saving. ...... But can a stone cold pacifist truly manage her way through Horrortale? Okay, a quick note. This story is rated mature, blood, gore, some more sensitive things that you might find extremely suggestive. Since people are enjoying my Nightmare x Reader story, I decided to do a little bit extra. My updates with this book will be a bit slower. (Totally didn't write this story because I wanted to do a drawing of horror for the cover.) This story is kind of a slow burn, but unlike my other story, the reader is no pushover. Like in the The King's Queen, the cover DOES belong to me, so please do not steal it, etc. Remember these important keys when it comes to reading the story! (Y/n): Your name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color
