Summary
A collection of oneshots and shorts based off one-worded prompts from the September Month of Monsters Writing Challenge from my Discord server. Prompts will be listed in the first chapter, and they range from fluff to angst. Feel free to check out the first chapter (directory) to see what each prompt is about!
Fair warning, most will probably be Sans or Frisk centric.

Summary
The power of Determination is a strength that humans have in spades. It's what let you journey through the Underground, it's what kept you going in spite of it all. It's what drove you to try and SAVE Asriel... by any and all means. But what happens when that Determination falters? What happens when Determination rots under the weight of what you've done? What happens when you lose the will to keep going?

Pacifism Cannot Break Barriers by BornWithaSpade

Summary
“How do you hold a psychopath?”
“…with both hands. Because someone did that for me when I thought I was the monster.”
Frisk has done it—gotten to the end, gathered the souls, spared everyone… Yet, the barrier stands strong. Madness ensues when humans start falling down to the Underground again… and the true enemy manifests in the form of a glitch between worlds.
Chara is back. Papyrus has a gay awakening. You take the role of the player. Asriel reconnects with his feelings. Sans reconnects, in general.
(Kind of my thoughts on all three endings mixed together. A little AU-y, especially with Chara's story. May not be 100% accurate to the series, some bits may be cringe taken seriously, others may be out of character, but that's fine. Headcanon: Paps is 18-24, Sans is 26-30.)

Summary
Somewhere in the RUINS, a human falls. This time is no different from the last.
But then?
People are forced to leave those they don't want to leave.
People are forced to lose those they don't want to lose.
People are forced to forget those they don't want to forget.Something snaps. A lone flower watches from afar. A Skeleton anticipates what's to come. And when that day DOES come? The final verdict will be given.
TL;DR - DUSTTALE but it's not JUST Sans centric

Summary
Sans can dodge the attacks of the thing wearing human's skin, but he couldn't do it forever. His stamina wasn't infinite.
Chara is able to exist and have consciousness despite their death, but they were invisible for everyone. They couldn't do anything.
Yet, despite the differences between Sans and Chara, their goal was the same: stop the endless Genocide Time Loop.
Or: Sans and Chara make a deal and maybe bond as they try to save the Underground.

Summary
Aka my take on Chara during the genocide run based off my interpretation of their chara-cter (haha) with canon hints and the narrachara theory!!
Also Chara literally says the title in canon if you commit genocide twice in a row
Series
- Part 1 of Aw shit my UT phase is back
- Part 1 of Dreemurr Family Centric!!

Summary
A can of ravioli was in the cabinet, so you decided to just eat that. You got it ready and put it on the stove, watching and waiting.
Suddenly, a loud buzzing from your phone alerted you! You grabbed it from the counter, and checked the notification. Oh.
Oh…
WELL! Turns out Monsters were real the entire time, aha-!
------
Monsters rise up to the surface under their own laws. All it takes is for one small encounter, and one note, before you find yourself surrounded by skeleton Monsters. Each one carrying their own personalities, and each one being as unique as the last. It doesn't take long for you to adjust and make friends, but maybe they want to be something more...?

Summary
Mega-crossover monstrosity. Rewrite of a joke fic i made on wattpad years ago (“Sans x Grian: Murder in the Mansion”), except better written and pumped with more cringe
“After Frisk frees the Underground, Sans is forced to face a life he never expected to have. Juggling depression, multiple jobs, his education, and a debilitating crush on a certain rainbow-feathered human, Sans can’t catch a break.
To make things worse, a mysterious serial killer pops up in his city, stirring trouble all around.
He’ll have to do a lot more than HOPE if he wants to get through this.” -

Summary
Sans heals a skeleton monster after weird magic brings him over to his universe.
Red thinks he's saved by an angel. Sans doesn't know he's become a boss monster ages ago.
(Sans thinks Red's out of it. Papyrus thinks Red's okay, even if his standards are low. The crowd thinks Sans will be very much wooed by the stranger that appeared in Snowdin. It's always the skeletons that have the best fun out of all of them.)
Delirious Red x Flustered Sans

Summary
There were other humans before the last – the one that freed all monsters – that much was obvious, but there were more than six others.
Humans Souls could shatter if they weren’t handled properly, this was something that not most people knew. The only people who did were the ones guilty of committing the action.
Or
I came up with an idea during history class and now have vast amounts of motivation it’s crazy

Summary
After a few resets, Sans and his group are finally on the surface. The kid hasn't made a move to do it again which is great. Sometimes random bouts of pain pop up but he'll be fine.
Well except for the nightmares and the weird shadows he has been seeing around the kid and that flower that is. With all this nausea he doesn't think he can 'stomach' this all-!

Summary
Sans is tired, he's been through so many of the player's runs that he's had to start doing runs of his own (in the literal sense). He's been picking up on clues he's left himself through his computer to help him find a way to keep him and his brother safe. The player's constant unwavering determination is putting too much strain on the structure making up reality itself. The Core can not reasonably function in these conditions so their collective magic has been weakening. It's on him to carry the burden of the Underground's situation and worsening conditions because no one else has seemed to notice.
Sans has to put on his big boy pants and finally give a shit. You've forced his hand.

Summary
He was tired of this. Tired of the golden hallway, tired of the Dust on the wind… tired of dying. This time, for once, Sans decided he wasn’t going to die alone.
OR
Sans uses the last of his strength to Shortcut back to Grillby and Alphys so he has at least one timeline where he dies with someone by his side.
