TW: Swearing and slight gore Y/N reincarnates in the anti-void as a Voice... Will he befriend error or will they make them hate their guts? And will they meet other people? Only time will tell. Hello, this is going to be my first book and idk if it's going to be good so meh :v This story was inspired by transported as a voice by Virus_bOi, I obviously do not own undertale and I don't keep up that much with the fandom, so some personalities might be different, but hey. I can just say that it's a different multiverse ¦ ] The cover image is from Shira Wolfiecute on tumblr

"the healer likes t' sleep. like, a lot." Axe looks at the sole female AND human member of Nightmare's subordinates. She was only ever awake for about 8-10 hours a day, rarely ever 12, it was both fascinating and irritating at the same time. He was damn sure humans would be awake for more hours than that, he even asked Murder at the time if it was normal. Said skeleton didn't give a single care though, his words: "who cares, makes her more tolerable. 'sides she gets her job done." The cracked skeleton just couldn't shake off the feeling that there was more to it than meets the EYE. ━━━PHOTO CREDITS: Whale鯨豚 [@Whale5511] on X! ━━━MOST NOTABLE RANKING: #1 in sansxreader, horrortale, something new and badsanses on 23/12/2025 #1 in undertale on 25/12/2025 #3 in bittersweet on 24/12/2025 #2 in sans 18/08/2026 #1 in reader on 18/08/2026 ━━━━━━━━━━━━━━━━━━ DATES PUBLISHED: 001 ━━ July 29th of '25

(Y/N) was an average kid on the surface. They had learned about the war between Humans and Monsters and that they should never go to MT. Ebott. It was dangerous there. And you knew it. But you where determined to find your older sibling who had left to find you both a home. They had gone to MT. Ebott for you and you had to find them. Your big sibling meant the world to you and if you just sat down and did nothing you'd be letting them down. You had to find them... You had to find Chara... Undertale belongs to Toby Fox Cover Art and all other art in the book is not mine unless I say otherwise

The barrier is broken, freeing monsters from the Underground to the Surface... Only the Surface isn't as Frisk remembers. Apparently, heroes are taking the stage now, Earth's most mightiest and most dangerous. Sans is being flagged as one for his immense well of magic power. How will this ragtag team that can barely hold themselves together do when you throw a lazy, pun loving skeleton into the mix?

With the underground finally free, Sans the comedic prankster, wanted a nap. Except this time, Sans would find himself in quite the pickle. A purple portal, the gaze of countless eyes staring endlessly into his hollow skull. Tired, Sans decides to ignore it. Yet fate doesn't wait for a slacker who is only there for banter. ------------------------------------------------ My first fanfic, Feedback is appreciated I use tool assisted apps to help edit my grammar.

Timelines, genocides, deaths, ... It all stopped suddenly, leaving a hole in the stream of time. How will Fate repair it ? Will the souls participating in this stay themselves ?

Izuku Yagi, you've read the many stories on this kid millions of times so why not make this one a bit different. So strap in because we're going to be one hell of a MAD time.

The sanses glared at the new entity at their world in fear but overtime their fears have lessened and started to adopt the new entity as their own. Afraid, of the faith might brought on to them they just braced for the best. This fanfic is made around 2022-23 so don't expect good things especially at the first few chapters of this book! (Also my English isn't my first language so bare with me! Thank you!) <[Requests are always open! I suggest you request at introduction page to avoid confusion!]> !!most definitely the cover isn't mine!! !!Non of the arts,video,AU are mine unless I told you it was mine!! !!credits to the au creators, and Toby fox for creating Undertale!! -Myste-Rey/author (Now Rein!)

You are Kris's soul. However, the thing is, Kris hates being controlled, and you don't want to remain having a random vessel rather than a body of your own. Maybe everything will get better after TV Time.

When a power source of a machine called the Dimension Machine, which keeps all dimensions separate, is stolen, every world in the multiverse starts to slowly merge into one. Now, it is up to a group of heroes of other worlds to save the day. Although none of them know each other well, it is now their duty to retrieve the Dimension Machine's power source and save all of the dimensions from mixing with others, including their own.

30 years ago, a devastating event occurred. A Spatial Quake struck Earth and killed over 150 million people. However, it also lead to Pokémon gaining the ability to speak human language. The bonds between humans and Pokémon have never been stronger. In the present day, twin brothers Izuku and Clover Midoriya, along with their neighbor and friend, Shido Itsuka, attend Tengu High. Everything goes as normal until they end up getting caught in a mission lead by Ratatoskr and the three end up stuck needing to date and make Spirits fall in love with them to save them. As if that wasn't crazy enough, a horrible threat, far greater than any Spirit, is seeking to destroy and conquer anything and anyone that gets in his way. The evil Lord Drakkon. Intergalactic being Zordon needed a way to counter this, as the Zordon from Drakkon's universe failed to stop him. Luckily, the original Tommy Oliver had a plan and made multiple, far more improved Master Morphers. Now Zordon needed to find some teenagers with attitude to help. Now, Izuku, Clover, and Shido, are Power Rangers and destined to save the universe, no, the multiverse, from the evil Lord Drakkon. Will it be easy? Heck no. But they won't give up. Rangers forever, defending together!

Yet another book of epic art because the other one is full. I'll also throw in memes from time to time along with pictures of my dogs, news, announcements, and other randomness.

Alternate Future Of The World. Includes Crossovers From GT, UT & SU That Are Marked With DG![Crossover].

Undertale: Black Heart - Volume 1 For generations, monsters have remained trapped beneath the surface. With no freedom in sight, the Underground has changed. Monsters have adapted to its harsh environment, becoming stronger, more aggressive, and, in some cases, twisted by generations of survival. Yet there are still moments of peace. Chara and Asriel are two children who spend their days exploring the Underground together. During one of their games, Asriel teaches Chara about monster souls and discovers something strange about Chara's Soul Trait: a red soul surrounded by a black outline. Neither of them knows what the black means. They plan to ask Sans. But before they get the chance, everything changes. Chara suddenly attacks New Home, leaving destruction throughout the kingdom and forcing some of the Underground's strongest warriors into battle. Gerson and Undyne fight desperately to stop them, while Sans investigates the mysterious cause of Chara's transformation. His investigation leads him back into the abandoned True Lab, where he discovers forgotten experiments involving Determination, gravitational magic, and the mysterious Singularity Eye implanted into him when he was young. As the battle reaches its breaking point, Sans is forced to activate the full power of his experimental eye and confront Chara himself. But defeating Chara isn't enough. Something else is inside their soul. Something that isn't Determination. Something Sans eventually identifies as HATE. After extracting the mysterious energy from Chara's soul, the immediate crisis appears to be over. But the investigation has only raised more questions. Why did Chara's soul already possess a black outline? What exactly is HATE? Why did it react to Sans' Singularity Eye? And what really happened to the Royal Scientist who created it? Deep beneath the Underground, an ancient laboratory begins to awaken. And something that should have remained gone... is coming back.

This... is the world of Undertale. Frisk is searching to collect all the LOVE and EXP in the Underground. (First in a series, prequel coming soon)

(yes i renamed it because i saw a au which had the name. and no i didn't do the same with the title image as i'm a low quality creator) a au which was at the begining a sort of mess of ideas and mutliple ideas of au and a humongus rip off of underswap (the fanon as i didn't know that ts!underswap) which was so near to his canon version i decided to change it all and time by time, fusion of ideas which given me other ideas it became totally different. i might not continue it (atleast not now, not that anyone seem to be captivated by this ^^,) plus i made posts on reddit and tumblr to ask something, but as mostly nobody awnser for now i don't know what way i should take (i have two ideas, more or less chaotic).

After Undyne sees Sans using his full strength on a surprise ambush, Sans gets forced into a promotion from Sentry to actual guardsman, still trying to do the bare minimum while Undyne forces him to give it his all. I don't have any money for commissions for the cover so I just gotta hope I hit it big and get fanart or we sticking with the Tumblr header that's not centred. Other than that uhh, credit me if you do anything with these guys in your work. Also isn't it kind of weird the only change I needed to make for this story to work is just to delay the time it takes for some of the humans to fall into the underground?

DISCLAIMER: I will ONLY share the INFO and the first part, so this will be on... A long, long, long, long, long, long, long, long cliffhanger, because.. Uh, I'm rewriting 25 chapters, because of.. Alot of reasons, so, I hope you understand ! What if.. Wait, no, no, that sounds wrong. ... A JESTER'S SPINNING LIGHT: MAIN ROUTE You wake up in a strange place with no idea how you got there. A mysterious figure gives you a VHS tape and tells you to move forward. So you do. Along the way, you'll meet familiar faces, make new friends, encounter strange memories, and uncover things that perhaps should have stayed forgotten. But something about this world feels no okay i give up writing this. Who are you? .. Who is "You", rather?
