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

Sans AU x reader one shots
I get random ideas for X Reader books but I'm too lazy to actually write a full one so... Here are some one shots that I probably stayed up all night thinking about, until I finally wrote them. Sorry it's not the best quality, but I tried 乁( •_• )ㄏ
Story of Forbidden
"I am no ordinary "Sans" you see. My name is Forbidden. And this name is my whole existence to the different world that I once came from. I should start from the very beginning; where my life changed." For countless times that the human did a genocide run, they never killed Sans. Why even though they killed everyone else in the Underground? The answer is much different than expained. They are not DETERMINED enough. But what happens when change starts to happen in Sans' world. What will happen to the skeleton? What happens to his universe? ~•~•~•~•~•~•~• It contains some mild and offensive language and spoilers for the Underverse. Forbidden Sans belongs to me Everyone else mentioned belongs to their rightful owners.Complete

Y/N the Creator (Alphatale Fanfic)
An Undertale fan gets reincarnated into the Alphatale Multiverse. Will they use the knowledge gathered from their first life to their advantage? Or will they perish, fighting against the Gods of Alphatale? The writing in the first chapters is pretty bad, but it gets better. Reader x SS!Chara in the later chapters. This is my first book and English isn't my Mother Language, but I'll try my best. This story takes place in the Alphatale Multiverse. It is not the same as the original Multiverse, so some things may be different. Published: 12 August 2023 Completed: 20 January 2024 I do not own any pictures shown in this book. The cover image is from productionsoxy on Aminoapps. ---------------- #1 in reincarnated out of 1000+ (2 September 2023) #1 in cross out of 1000+ (8 September 2023) #1 in error out of 1000+ (29 September 2023) #1 in errorsans out of 1000+ (1 April 2024) #1 in ink out of 1000+ (7 November 2023) #2 in multiverse out of 1000+ (12 September 2023) #2 in dust out of 1000+ (1 April 2024) #3 in sansaus out of 1000+ (28 September 2023) #5 in undertale out of 1000+ (26 September 2023) #5 in infected out of 1000+ (17 November 2023) #5 in sans out of 1000+ (9 November 2023) #6 in undertaleaus out of 1000+ (29 September 2023) #9 in sansau out of 1000+ (12 October 2023) #26 in reborn out of 1000+ (9 October 2023) #29 in nightmare out of 1000+ (17 November 2023) #101 in dream out of 1000+ (17 November 2023) #1 in 404 out of 205 (25 August 2023) #1 in alphatale out of 93 (10 September 2023) #1 in diety out of 145 (19 September 2023) #1 in kingmultiverse out of 25 (22 September 2023) #1 in alphasans out of 19 (17 November 2023) #1 in error404 out of 166 (27 December 2023) #2 in omnipotent out of 202 (9 October 2023) #2 in epicsans out of 124 (17 November 2023)Complete

Discordance In The Balance (Nightmare and Dream x Corrupted! Reader)
After becoming friends with none other than the guardians of the tree of feelings, you realize more things are going on than the guardians care to reveal. After attempting to help them you end up corrupted and your friends trapped in stone for 500 years. . . Currently rewriting!! This is a sans x reader fanfic so don't like don't read. Reader is gender neutral and there is 18+ stuff in this book so please keep scrolling if you're under 18! So minors please avoid this like the plague There will be warnings at the beginning of chapters, if there's something I should put a warning for please tell me. Y/N = your name F/C = favorite color See anything else to put ill put it here /|\ ---WARNING--- This is mainly for fun and ideas put together from what my brain spews so continuity errors may happen and i will try to fix them accordingly. 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
