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

In the '20s, the animosity between humans and monsters has reached the worst parts of society. Seeing as scums or worse, monsters have made their way in the shadows until they become mobsters or even (unofficial) political power, which forced humans to no longer underestimated them. Our story starts in a shady nightclub, owned by a greedy and prideful human named Cornelo who hates monsters. Despite that, he's about to make a deal with one of them this night for a lot of cash. All things are set up and he's planned to use his own toy : Leo, a talented, red-haired singer who's going to entertain the monster. But what the Don didn't know is that "guest", Sans the skeleton, has already gathered some information about the singer and he's eager to finally meet him, and play with him. And what about Leo himself ? Will it be a pawn, a prize, or something more for their little game? Or will the angel of the stage be a player as well ..? Credits : Based on the game UnderTale by Toby Fox and "Sooner or later your gonna be mine", a story written by Staringback and adapted in comic by Melikas. PS : It's a MobFell/MafiaFell fanfiction. If you dislike racism, murder, homosexuality, or monsters... Well, why are you searching for an Undertale fic in the first place ?! PS 2 : I'm French and this story will be only write in English because most of the comics I read and the dubs I listen are in English and now when I imagine Undertale stories it's mostly in English (even if mine is bad :P).

A story where OUR Classic Sans gets stuck in an au where mobsters lived and meets a different Frisk and a version of him. Will there be romance or fire along the bridge. Will Sans get home and leave Frisk alone or stay long enough to romance another version of him on accident. [I loved the comic/story of Sooner of Later You're Going To Be Mine but also hating the Frans portion of it]

What if..someone became the same parasite that was fresh? Not as the skeleton, but the parasite, the thing is, when this parasite gets memories of another life and their feelings...they become..protective of their host...and train..a lot with the host and without the host.... Now all they want to do is protect fresh, and a few select skeletons. They wonder what will happen when they change things? (Different things happening, different personalities, etc not what you think Uhh idk.

It's been a while since Horror's world could be considered even remotely kind. But a newcomer drops in, and reminds him that there's still sweetness to be found in life. Horror will be damned if he lets him escape. In the caves behind my house, I found the ruins of a softer world. Kindness couldn't save them. -Joey Comeau cover art belongs to bung0us on tumblr, check them out!

What if something happened to everyone except About three and it made their emotions more..entense and made them like yanderes? What if the one of the three that wasn't effected was fresh sans because he was a parasite except his parasite is different and protects its host? Now add on to the fact that fresh was also now trying to keep the balance of good and evil with a game of tag. Then add the fact that fresh doesn't really feel to much of the emotions but can still feel them but still adds his logic into that. Then add the fact the only other person thats not effected is error the god of destruction who now hides in his anti-void and now only fresh visits error to talk to the only other person not effected but whatever that messed with either of their friends that made them like yanderes. Along with geno in his safe screen? (It's probably all going to be different. This was inspired by a story called foreververse in ao3 for undertale. Its very interesting so you should go check it out. mines going to be different then theirs but a bit similar with the game of tag. There's only two chapters so I'm not sure how it's going to go exactly so mine might end up too similar or very different. Idk I'll do my best though. But that story is very unique since I haven't seen anything like it. They are many unique stories that I've found and haven't found. That story made me think and made me want to do this so here it is.

Formerly known as, "I Became the Forced God of Creation". !!STORY COVER IS MINE!! What if.. Error isn't a forced god but Ink is? What if Ink had enough and committed death and chose someone to be the next Ink, the forced god of Creation? What will happen next..? Will they end up like Ink or.. A brand new fate and destiny awaits..? (FGod concept which is not mine and this story is an original idea of mine. Undertale doesn't belong to me nor any of the characters shown in the story. That's all thanks for reading.) (FGod Ink belongs to me, FGod Error belongs to Harrish6.)

The Universe is vast. And if there is anything confusing that having two of yourself, it is having a vast plethora of others similar to yourself, that have the same name, and mostly the same form. However, that seems to be the least of Classic Sans's worries when he gets to meet all of his AU counterparts for the first time. With the knowledge of every reset under his belt, and experience at his side, it seems as though he will have to teach the other forms of himself acceptance, understanding and how to be a good family while he himself hides what hurts him the most. However, everyone has their boiling point, and it seems that there is no such thing as diamonds in the rough when it comes to the subject that is mister "W.D Gaster' and his troubles. In the end for Classic, everything boils down to depends on everyone around him, and himself to truly get things right. "No one has to be alone, No one is born evil. Everyone can make a difference." // Welcome to a general fan-book that is going to be written in a script format, because I have nothing better to do in my life and I am literally just wasting away here. Please help me, I am going to die of boredom... :'(// //The cover art is not mine. Please, if you know the artist, remind them of how great their art is and please give feedback on my chapters. There is no set pairing either. So also keep that in mind. //
