Summary
Here we are again! Another series of Undertale one-shots following the Fictober prompts and featuring the skeleton brothers as love interests to either my nameless or named girlies.
Just like the past two years, if you'd like any of these to be turned into fics, then please let me know in the comments! If enough people show they're interested, then it'll be added to my list of future fanfics! Five requests are what's needed for them to be added.
And if you choose to wait till the end of the month to read, that's okay! Requests can be made up until November 7th, when I post the list of the lucky winners!
Hope you all enjoy!

Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.

A brother adored, a brother scorned. The choices made by the masses that led to a war. A kingdom divided and the middle ground neither can claim. A past that should have been long dead resurfaces- and it changes things. The sun and the moon shine brightly- but what about the beauty of the stars?
Or; Nightmare and Dream are at war, and their friends have to deal with it. A part of the past the twins- especially Nightmare- have thrown away comes back. Things change; but is it for the better?

Summary
As a person, falling in love wasn't on the top of your priority list. If it happened, it happened, but you weren't all too bitter if it didn't. Maybe whatever social higher power wasn't too happy about that, so it just had to partner you up with some nerdy idiot who flew too close to the sun and ripped a self-shaped hole in the middle of reality itself.
And then you also fell in love with his brother. Too bad that you aren't too up for polygamy.
Inspired by Milk Tea and Souls by Lady_Flame96 and Soulfound by yeo_sin, Title inspired by Baile Involvidable by Bad Bunny

A Totally Fantastic Guide To Vigilantism by Apathetic_Blossom
Fandoms: Undertale (Video Game)

Summary
The world has always dealt in absolutes. It was absolute when it took Error's parents away from him, leaving behind three siblings with nothing but each other to rely on. It was absolute when it coaxed him to become something greater than himself, fueled by the pain and desire to right society's wrongs. It was absolute, when it decided that Error was the king in life's extravagant game of chess.
Or, Error is a friendly neighborhood vigilante until he's not.

Summary
Okay, so admittedly none of this has gone entirely according to plan.
Actually, most of it did the opposite of that.
--
OR:
Sans runs afoul of some pirates once or twice, and it turns out there are a lot of things he doesn't know about the universe at large - things he really wasn't ever supposed to learn.

Summary
Инк, конечно, забывчивый, но все самое базовое, важное, он чаще всего помнит. Поэтому Эррор, наткнувшись на растерянного Инка, неспособного вспомнить кого-либо, с кем он когда либо взаимодействовал или же как он тут оказался, увидел в этом не что иное, как заманчивую возможность. Инк же знает где Омега Таймлайн, так что Эррор может просто пойти и уничтожить его, верно…?
Как оказалось, память Инка осталась в лучшем случае ограниченной, что приводит его и Эррора к погоне за подсказками о предыдущей жизни Инка в Омега Таймлайн, раскрывая ту сторону Инка, о которой Эррор не догадывался.
…Главное, чтобы Инк никогда не вспомнил о том, кем они друг другу являлись на самом деле.
