I've seen some Undertale fanfictions where readers and original characters are sucked from our reality and transported in to the reality of Undertale and it's several aus. I got inspiration from some of the stories, I don't exactly remember the name of the stories I apologize but I give credit of the original idea to who ever came up with it first. any how, instead of the character staying human, once they are transported they're turned to skeleton, so the magic in their body can get use to not only the transfer through the void, but so their body can be use to the magic drifting around in the monster world. cover art is made from a picrew dress up/make a character site. all credit to the creator of the picrew! slight trigger warnings for those in need racism towards monsters harassment transphobia homophobia slight panic attacks here and there onwards to the story!

Geno is the Captain of one of the most feared pirate crew in the seven seas along side his Quartermaster, or first mate as some call him, Error and Fresh, the Master gunner. While from the first look Geno looks fragile and unfit to lead a crew, he's actually cunning, smart, reliable and skilled in fighting both with swords and pistols. He always kept his word an put his crew first, always listening to their worries and suggestions. Most decisions where decided via vote. While his judgment was always fair and accurate, so where his punishments and no one was able to get away from one if done something wrong. No one was able to hide anything from the captain, he knew a lie when he saw one. Reaper is a siren shunned by his own people for being "too dangerous". I mean it's not his fault that he was born the way he is. And those few deaths where accidents! Yet even if he tried to explain and redeem himself, he was still exiled and every siren or mermaid he meets never come closer, only further away. And so he wonders the seas by himself, doomed to be alone for the rest of his existence. Or is he? [This is inspired by a song "Siren" by Kailee Morgue and I really wanted to write it before I forgot about this Idea.]

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.

so I oh ways want to make a reborn as killer sans, but we're mentally unstable, of course, due to the rest and our past memories, which we can't remember what we were anyway! We know everything and everyone, so why not mess with them. This going to me fun!!!

Aliza has created another reset only this time she isn't facing the horror house alone. He older sister has joined her, however her older sister doesn't seem to be able to show fear. What would happen when Sans meets her? How is she there? *Art and alternate Sanses or undertake universe I guess, belong to their rightful owners!*

*SPOILERS TO AT THEIR MERCY. THIS IS A SEQUEL* The multiverse was finally at peace, and Erratum felt as though they were finally able to breathe a sigh of relief as the peace lasted over a year. They knew better, deep down, than to believe it would last. The itching voice in the back of their mind assured them that this was far from over, at least.

These four walls are the only sight he's ever known. There is nowhere to escape the prying eyes that watch his every move day after day. Surly, there has to be something better beyond this gilded cage? Started 2/25/25

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

Nightmare has been fighting for a very long time. He fights to uphold a one-sided balance. He fights to protect the few who stand beside him. Most of all, Nightmare fights so that he'll never be weak ever again. But the Guardian of Negativity is getting tired. Nightmare is not sure if he can fight for much longer. Started 11/5/2024

Sans doesn't remember a time when he had his own name. He always wakes up as a Sans, but everything else is constantly changing. He is an observer meant to simply watch the AUs, not change them. He has believed this for a very long time. When Sans begins to learn more about his Multiverse, and the problems in it, the burning urge to protect is reignited. How can a nameless, bodiless spirit change anything? The entire Multiverse may just depend upon him figuring it out.
