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
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
You died. Sans died. But in the void between life and death, you found each other, and a chance to live again.
Merged into one body with a dying child skeleton, you wake up in the middle of a brutal war between humans and monsters. With baby Papyrus to protect and your brother Gaster's experiments turning you into something more (and less) than human, survival means running, fighting, and holding onto whatever shreds of innocence you can preserve.Or: Isekai War AU where you get hit by Truck-kun, merge with Sans, become a child soldier, and eventually end up in a polyamorous found family with 14+ skeletons. Features: PTSD, creative use of green magic, so many puns, and the aggressive pursuit of a normal childhood for Papyrus.
no stripes or brother/brother are involved in romance.
Ask not for whom Truck-Kun honks, Truck-Kun honks for thee
This is entirely plotted out and outlined but will not have a set release schedule

Summary
“Thanks, Paps.” Sans replied, taking the blanket and dropping it over the sleeping human. Proceeding to give the child an affectionate pat on the head. The sight made Papyrus think of when he and Sans were younger.
Seeing his brother in such a state filled Papyrus with his own feeling of euphoria. After all his brother has done for him, even including all the times he has annoyed him with the puns, Papyrus felt that Sans deserved his own bit of happiness. His own chance to have the life he wants.
Or essentially five times of others witnessing Sans acting as a Father towards Frisk, the one time he admitted it.

Summary
A sweet little series set in a world where monsters had been captured from the beginning instead of shoved underground.
Eventually, as the years and generations pass, both humans and monsters slowly forget the monsters were ever free.
We follow the story of an aging little zoo hoping to expand and take in a few monster pups. And the stories of several monsters who find themselves being transferred to the place.

Warning this story contains self injuries and domestic violence and abuse.
What if Aelita's new begin on Earth with missing memorys causes a bigger problems than in the show. With a slightly traumatized Yumi. Which makes her a bit more mature than in the show.

Wat als Aelita nieuwe begin op aarde met een missend geheugen grotere probleem veroorzaken dan in de show. Met een licht getraumatiseerde Yumi. Die hierdoor wat volwassener is dan in de show.
De tweede fandom Undertale is toegevoegd. Maar is vooral als wat achtergrond opvulling.

Summary
Ink desperately wants a soulmark. He wishes he had that little sign of existence, a tiny mark on your chest to signal that there was someone out there who would impact you so deeply it went soul-deep. But no soulless being has ever had a mark across the entire multiverse, much like how no one with a soul has ever managed to lose theirs. He doesn't care. There's no point in not trying, right?
Or:
After a close call with Dream almost discovering Ink's lack of a mark, and by extension his soullessness, Ink decides to give himself a soulmark. It doesn't go well.

Summary
I wrote the Papyrus sickfic I wanted to read, and now I have magnanimously published it.
✨️you are welcome✨️
Also known as: that time Sans and Papyrus accidentally swap magic and therefore magic ailments, neither of them have a great time dealing with the other's issues but at least they can help each other out? They may have to have an honesty about it.
