Summary
His grip on the knife tightens until the bones of his knuckles ache.
He should do it. He has to do it.
But all he can see is how small he looks. How tired.
All he can feel is how badly he wants to reach out instead—just to touch him, just to make sure he’s real. Not a memory. Not some cruel hallucination born of guilt and longing.
His hand lowers, only slightly.
His knees feel weak. His vision blurs, not from tears, but from something heavier. The kind of grief that doesn’t cry—it just sits, low in the ribs, thick and aching.
He needs to end it now. This version of Nightmare doesn’t even know what’s coming. There’s no malice in him yet. No corruption. No hatred.
Just a boy asleep beneath a tree that he used to call home.
It’s so easy. It would be a mercy.
And Dream can’t move.
Because no matter what he tells himself—about the stakes, the mission, the cost—when he looks down at his brother, all he sees is the child he failed to protect.
Dream’s mission was clear: assassinate Nightmare, erase the corruption before it ever took root. But standing in the past, blade in hand above Nightmare's throat, he faltered.

Summary
Red blares into your eyes as alarms scream, and wail into the air.
Their shrill shrieks mixing with your own wheezing breaths. Even as the helicopter sways precariously, the various vegetation its tangled in groaning and threatening to snap under the immense weight, you still can't find it in yourself to tear your eyes away from your pilot.
Or, rather, what remained of her.
The metal, having come flying off of Runner's copter and straight into yours, painting the cockpit in shades of red and grey, wasn't the only piece to crash through the windshield. But it was the one that did the most damage. Crashing through the window, and sending shards of glass directly into Strong's eyes, the metal had sliced... No, not sliced. That wasn't the right word.
The action was more akin to... To... It, fuck... Her face had the appearance of steak after you force a blunt blade through it; torn, with bits of fat hanging freely, and muscles shredded rather than cleanly cut... crushed bone and blood oozing from what had once been her jaw. The muscles and veins still spasmed and twitched, struggling to continue doing their job.

SOUL's Divine Fire by Virtual_Faye27

Summary
Bridget Hartkroft would like to state, for the record, that when she left Camp she didn't expect to run into an entirely NEW Pantheon! That seemed like something a Big Three child or one of The Seven would deal with. Not a crippled daughter of Hephaestus that wanted to get away from her traumas and stop weapon making.
But here she was; Nowhere near her fellow Greeks, the Egyptians, Norse OR the Romans and she HAPPENS to be nearby when Magic-born Monsters finally escape their magically sealed prison and now she encounters a lot of Skeleton Avatars of Gods and their Mortal followers! At least with the creepy ones they kill the things after her and can be banished if she throws sharp pointy things at them when normal offerings don't work. The 'good' ones make her wish she could jump into fire like her half-brother could just so they would Leave Her Alone.
For the Undertale Multiverse when a new AU is born with almost as much divine energy coming from it as Reapertale they just HAVE to investigate! And that one weird SOUL-ed kid threw food and weapons at them they just HAD to stick around! But why was she so sad and angry all the time?

Summary
In a world of gods and guardians, it would be expected that some would fall for mortals, and inevitable in such cases that demigods would result.
Killer and Cross are two such beings, half god and half mortal. With abilities mortals shouldn't have, but also not quite as durable as full deities, they reside somewhere in the middle, and unfortunately certain people would take advantage of that. Without parents around who would protect them, they must fend for themselves as they run to escape the prison they were trapped in, and this was how they ended up inside a tentacled skeleton's mansion without knowing what they were getting into. While the brothers now must figure out who they can trust, Nightmare and his friends have to discover these two teenagers' past before what or whoever they are running from finds and drags them back into their personal hell.
Hopefully these two can warm up to the guardians and gods despite what they've been told...

Apathy's a Tragedy (And Boredom is a Crime) by Amy_Mask8119

Summary
Sans is an ordinary guy living an ordinary life. He may be the laziest pun-lover ever exist, sure, but there's nothing unusual about him. Average grades with no standout subjects and a dull, repetitive jobs shaped a fixed routine of wake up(late), eat, work, eat and sleep. Even birthdays blurred into the same numb monotony when you celebrate it every year.
Maybe that's why, when Alphys, Head of the royal scientist of monsterkind, made a major breakthrough in alternate universes, He was one of the first in line to explore them.
Because surely, meeting new people will be enough to satisfy his boredom, right?
But alas, new people are still just people. And the more you know em, the less exciting they become.
Too bad that boredom is a crime that he'll do absolutely anything to avoid committing.
So when he stumbled upon a clash between the Bad Sanses and the Star Sanses, instead of running away, he found himself a nice, safe spot at a distance to sit back and watch.
He never expected to get caught.
He definitely never expected to get dragged into the center of it all.- Language:

Summary
The whiteness greeted you as you woke up again. It felt almost suffocating, especially when the only other people with you didn't exactly look or act normal. You just wanted them to emote, even a little bit.
All you wanted was to not be alone but no. You were reborn as Ink after you died in a lonely ditch. Now you have to navigate the vast Multiverse with your knoweledge of your last life. As you get friends and foes alike, you notice that not everything you know is trustworthy. Especially when you're a little lost skeleton with questionable ability to feel.
After all, anything could happen in a place this big.

More info on CH19(As of 28/7/25 the first chapter has been rewritten to improve the flow and clarity of the story.)
(I will continue to edit earlier chapters bit by bit. When I'm done, I will announce it in later chapters.)
--
Error's done. Fate has been in control of his life for too long. He doesn't want to do this forced job anymore. No more. So he takes a risk.A risk that eventually makes Error terrified of what's to come. More for the ones he calls family than for himself.
Ink realises he's not the only one suffering from fate. He's just as trapped as Error is in this forced job. So Ink does the best thing he could think of. He helps. Well... That leads to more problems for both of them.
Fate will never go easy on them again.
or
FGOD Error and Ink are taken by Fate because Error broke the rules, and Ink discovered that Error is experiencing the same struggles as him. The multiverse Sanses must rescue them.
