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

(REWRITE OF THIS BOOK IS UP! It is called "Obsessive Love".) (I do not own the cover, Undertale nor any of the characters besides my OC's, they belong to their respectful owner. For some reason, I just see Error in the front instead of passive Nightmare.) Error, Forced God of Destruction and Destroyer of Universes was largely unknown unlike Ink, the Creator and God of Creation. Their fights were unseen by the AU's, none of the Monsters knowing about the Destroyer as Ink doesn't want them scared and Error gave no shits if anyone knew him or not. But Error's job is a complicated one, one that he is forced into, and he has to get involved to destroy the worlds. He doesn't touch the Original AU's, but the copies that Ink makes have to go. It was only a matter of time before something happened. Ink, in a middle of one of their fights, blinded Error, hurting him much more badly then ever before. In panic, Error ported into one of the Original AU's. Ink, fearing what Error would do, tells Dream about the Destroyer. Now the hunt is on for the broken, blinded skeleton. Meanwhile a blinded Error has been taken under the wing of another powerful Monster who has fallen for the broken Destroyer at first sight. But sweet love is truly beyond him. It is a obsessive love, a unhealthy love unlike any other. Nightmare would do anything for Error, and would do anything to keep him by his side as he goes about taking over all the AU's. Now to convince Error that he should be his and his alone.

(Old) Parasitic Lover (Yandere! Fresh x Error)

27 parts Complete Mature

Finally Giving up on his quest to rid the multiverse of it's Aus, Error decides to just stick to the anti-void and ignore the problems of everyone else and to try and enjoy his solitude (although ultimately failing at this). On the other hand, Fresh has also given up, but not in the same way Error has. He has given up being the nice guy and has taken to corrupting Aus in his rage at how unfair it was that they could live their happy lives, while the only emotions he was starting to feel were negative. One day, Fresh decided that he needed something new in his life, so he decided to go to the only place in the multiverse that he has never gone before, the Anti-void. By complete chance he ends up in the exact same place as Error and their worlds suddenly collide. (Disclaimer: I own literally nothing besides the plot) (Warning: Violence, potential profanity, boyxboy, kidnaping, mentions of rape, minor character death, attempted self-harm, almost knife abortion, and domestic abuse... so read with caution)
