After the events of the neutral route, Ryobo and his brother decided to reset and try everything again.

Once they fell into the Underground, and started the pacifist route, Ryobo couldn't help but feel like there was something very strange about Toriel that will soon take a dark turn after they reached the end....
________________________________________
A heads up from me, most of the chapters will be based off of the "Yandere Ralsei! AU" by andy-shempai (from Tumblr)

Also, if you haven't played Undertale and Deltarune, please do so you'd know who the characters are.

So Many Universes, So Many Possibilities by PinkHorsePro
27 parts Complete Mature
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
"Soulless" || Undertale + OC || Discontinued/Hiatus (being rewritten) by Miyuka1709
11 parts Complete
A Story about 2 humans in the Underground, Illys and Lily One with DETERMINATION and one with PATIENCE. ---------------------------------------------------------- Lily, a 16 year old girl who fell 2 years prior to the events (she was 14). She lived with Toriel in the RUINS ever since. Illys, your typical 13 year old girl. She grew up being distant and alone, and although that, she was actually a pretty curious kid. She heard about the infamous Mt. Ebott so she decided to see it herself. When she reached the end, she still felt like something was missing, so she did a RESET. Over, and over, and over again. ---------------------------------------------------------- This is like a 'Classic Undertale + 2 OCs' kind of story, so everyone else would have the same personality and appearance and stuff (Illys replaces Frisk as a protagonist.) Trigger warning : Blood + some .. strong language + canon typical violence I'm not affiliated with Toby fox whatsoever and this book is just for fun, All the artwork here is made by me. Also this is my first book, I'm so sorry if some of them are inaccurate or unrealistic, I'm trying my best. Feel free to leave feedback in the comments :D Thanks, bye! -Please read A/N

In And Out (a deltarune fanfic) by Juju_fna
32 parts Complete
This is my interpretation of one of my favourite Deltarune characters' (Susie) life after the Darkworld adventure. Deltarune and all of it's characters belong to Toby Fox, and there will be crossovers from Undertale, also by Toby Fox. There will not be too many crossovers. If you have never heard of Deltarune or Undertale, go check them out, or something. this story will include the ships lansie (lancer and Susie), and soriel (sans and toriel). These are what I think the ships should be called, so please no hate. (Yes, I know that Susie is way taller than I drew her to be, but, let's just roll w/ it, Kay?!?!). This was also my first story... Thanks, enjoy, and yeah! Bye! Completed story as of: 2/22/20 Everything after chapter 27 is extra...!!!

Undertale : Secrets (REMASTERED) by ItIsComic
31 parts Ongoing
Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that, despite being so long ago, always finds a way to bite back. A past that defines who he is - but he longs to erase. A past that doesn't let go, it clings to him despite his endless attempts to escape. And when someone finally attempts to uncover the veil, and fails in the process, what happens next? This book is a complete remake of the original Undertale: Secrets that was made nearly 3 years ago. By remake, I mean that this book takes the general plot of Secrets and basically "tries again". This will reuse elements of the original and cut out the parts I don't like while adding my own new ideas, effectively creating a new book. Whether you liked the original or didn't even read it, I hope you like this!! Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 17 March 2024 Finished: Not yet! Undertale by Toby Fox

Was this truly the last RESET? Sans wondered. But he knew only Frisk would tell, only this young girl would decide his future. He hated the thought of it at first, but hatred began to grow numb after he figured out he had no say in his own future. He had to admit though, Frisk was pretty reasonable, it was Chara who was the maniac. But she was gone now, so what was the anticipating, eerie, feeling that he had in his bones? The feeling that something wasn't right, of course, this timeline was already incredibly strange. The feeling sat in his in the pit of his stomach, tying itself into knots, until that fateful rainy day when all of his questions would be answered. So basically, this is a fanfiction of a fancomic of the game Undertale. Look, I'm gonna admit, I'm little stuck in the Undertale fandom, so this is my of slowly crawling out of it. Anywho, I strongly suggest you read the fancomic which this fanfiction is based off of, DeeperDown, before reading my story. Here, I'll give you a link. http://gettingdeeperdownwithundertale.blogspot.com/ Anyway, enjoy the story, it took me about 11 months to write, so please consider enjoying it, seriously. - Ya Boi, Fox

She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself.
