So Many Universes, So Many Possibilities by PinkHorsePro

After falling into the void, Error lands in a different multiverse. He saves two little babybones from the clutches of Gaster, and meets the protector of this multiverse. But, it doesn't go well. He freaks out and throws himself into the void once again, the children following behind him. It is then Destiney realizes that the multiverse was too similiar, with too many familiar abusers. But where could she send him? A minigod talks to her about multiverses in need of rescuing. She agrees to help her out, sending Error to them, the inhabitants all becoming very protective of Error. Error's old universe, after learning that they needed him but not why, travel to the universe he was in at the time to capture him. But, with how many friends he has made, they might want to reconsider their decision. For Error was hurt just as a lot of them was, and they will protect him with everything they have. I'm not sure if this description was that good, I suck at descriptions. This is based off Harris6's Falling Into A Different Destiny and their concept of Forced Destroyer. Please, if you haven't seen any of their books do go check them out. It is definitely worth it. I do not own anything except for the OC's I include and if I add a certain world to this. Undertale belongs to Toby Fox. Please be aware that this book will get dark and have many trigger warnings. The art does not belong to me, it belongs to it's original creator

Grouptale [Undertale AU] by FridayHater

What if the six fallen humans who died before Frisk never died and instead joined Frisk on their journey through the Underground? It all seems good... aside from Frisk. Why are they really in this timeline? What do they want? Join the other six as they try to learn about 'the eighth human', why everything is so strange and how to escape the underground.

Dual Stones - Undertale Fanfiction (COMPLETED) by IcyDuelist

Duska has something most people would call a traumatizing childhood which she only escaped from a few months ago. Now she finds herself beneath the very mountain she was born in with monsters around every corner. She decides to start her life again here, in the house with Papyrus and Sans, but monsters don't live the most ordinary of lives either. Duska's past is catching up with her but the wall of friends in front of her may be hit by the impact first. No pictures, videos or any other media belong to me unless specifically said. Will have some swearing in it. Undertale belongs to Toby Fox. Thank you for creating such a beautiful game! I FINALLY FINISHED IT!!!
