Summary
"O-okay, fine! Fine! I'll tell you, just don't laugh," she surrenders, face flushing hot, "you know about alternate universes, right? I told you?"
"Of course." He leans forward.
"W-well, there's got to be some universal constants across most universes, right? So, uh, I was just wondering..." and her voice softens into a pink shade of shy, "do you think we would be friends? In every universe?"
(Or: Alphys and Mettaton, across timelines and lifetimes and universes.)

Summary
Ghost monsters don’t have daemons — that is, until they become corporeal.
Napstablook doesn’t know this, when they end up trapped in Mettaton’s dead body.
Neither does their daemon.

Summary
So: he has time off. Time off means he is not performing. Time off means he has to do something else, and unfortunately, he’d already made the calls and set the schedules for his future plans within the first two hours of his free time, so.
(Time off means time to think. Time to think means time for his mind to wander.)
(It always wanders home.)
In which the ghost cousins are alone. Old habits, of course, are always there to remind them of a time they were not.
(Written for the Ghost Cousins zine.)

Summary
“Mrow,” says the cat, pinning them with two startlingly bright green eyes.
Napstablook stares at the cat.
The cat stares at them.
They stare back.
And bored with the inadvertent staring competition, the cat does a little stretch and pads right over to them to properly introduce itself, rubbing up against their knees.
In which Napstablook adopts a cat. Or, more specifically, the cat adopts them. Shenanigans ensue.

Summary
Ghost monsters don’t have daemons, and Napstablook knows this well — that is, until they possess the shot-dead body of their estranged cousin in a bid of desperation, and a snail daemon makes itself known…
(Or: an Entity NEO daemon AU. When you were once one being and now are split into two — entirely on accident — how can you even learn to live with your regrets, let alone yourself?)

Fandom: Undertale (Video Game)
25 Apr 2023
Summary
The subcategory of my (very, very spur-of-the-moment) Entity NEO fanfics that kinda spinoff a bit more from the main storyline, because as you can see I am terrible at putting anything longer than 2k in the designated oneshot collection fic.

Summary
Steve Harrington has stopped pretending to be human. Somewhere between Hawkins and the infinite timelines bleeding into it, he’s seen every version of himself (hero, babysitter, monster) and realized they’re all the same: meaningless performances in a universe that doesn’t care.

Summary
Five Pebbles is consumed by his own Rot, and dies. Or, that's what he assumed would happen, but instead he wakes again, bound to the cycle, trapped in a body that is not his own, and perhaps this is his solution: a mobile body, capable of bringing him down to the Void Sea, where he can finally, finally, find his peace.
But his so-called sister has never been able to just let him rest.
(Pebbles, Moon, and the Artificer: a story about surviving, old mistakes, and the families built in the strangest of places.)

Summary
“Didn’t think I’d get this far,” Kris tells Dess.
“Hey.” Dess taps their nose, and they peer up at it through their bangs, the vibrant brightness of her face. “I’m glad you’re here, harbinger. You’re going to figure this out.”
Kris hums, noncommittal. Somewhere halfway across the country their friends are finishing up final exams. A whole year out there, learning new things, living new places. So many things they’ve seen that Kris never has, never will. Certainly, their friends have traveled further beyond the bounds of Hometown than they ever have. Into some world that surely cannot exist. Some reality that doesn’t include them.
They know, of course, that theirs is a problem that can never be solved.
(When they’re ten years old Kris Dreemurr is shown a video by their mother. It is of a coyote that has been raised by a dog mother, with dog siblings, in a human house.)
On surviving your end and what comes next.
