Also, some information about her since I just kinda dropped the link and didn't elaborate. lol

So, she's a shape-shifting dimension traveler not originally from UTMV. (She is my self insert in a lot of things. lmao) She stumbled upon the UTMV Cluster (complicated lore I'll explain later) while exploring the Greater Multiverse and has kinda stuck around.

She can only shape-shift into living organisms. Doesn't matter if the species is fictional or has gone extinct, so long as it is, or once was, alive. (So, can't shift into inanimate objects or undead creatures, but can shift into mythical, made up, extinct or currently living creatures.) Her species can live to be several millennia old (she herself is roughly 3000) and are exceptionally vulnerable in their true forms. They use their shape-shifting as a shield, taking on the forms of being capable of taking on damage without being insta-killed, and only show their true forms to those they trust to A. Not take advantage of them while in such a vulnerable state, and B. Protect them from anyone or anything that may cause them harm. I like to describe showing their true forms as like, deliberately turning your back to a predator. (In other words, a very strong show of trust.)

And I high-key ship her with Blue, so guess who gets to see her true form on the reg.

She sounds so cool omg

I love shapeshifiting characters they give my genderfluid ass so much gender envy

Killer would suggest a threesome (joking....unless? which idk about you I'd hear him out)

He's gonna tease you about being jealous- which his ass has no room to talk he is the most jealous little shit there is but he will remind you he hangs out with you all the time

Originally the oneshot was gonna be with Amber, but since I'm talking about it on a Sans x Reader blog, I'll refer to Sans' s/o as the reader instead :3

So Sans would be sitting at a window stuck in his thoughts (probably when he's on the surface) when the reader walks in and sits down next to him to chat with him (maybe he's down in the dumps? Or maybe he's just distracted, I dunno)

They talk and the reader has a silly idea, so they take a dry erase marker and start doodling on Sans' skull

Sans starts giggling and takes a marker of his own and starts doodling on the reader's face as well. If he was sad or something, this definitely cheered him up

I have tons of little stickers I haven't used yet, so maybe the reader does too and they start putting cute little heart stickers all over his face, and of course he does the same to the reader :3

Papyrus walks in and he's like "???WHAT HAPPENED HERE???"

With a giggle and a dorky grin, Sans could reply with "we're being artists. look at our masterpieces"

I might write it if anyone wants me too, but I have so many oneshots and fanfics I keep writing and swapping between :3

I too have a million w.i.ps im jumping in between lmao life of a writer

That being said

Asking for a friend

-🐞 anon

Yuri and Sans talking to each other through Echo flowers as children, but they don't know it

And they find out at the most random moment of their relationship years later

He would casually look down at his body made of literal bones and ask what the plan is here exactly-

"But his ecto body-" is a ghost body, you can harm it but it don't scar plus he does still have 1 HP so like

If you keep your intent in check maybe but even then if you're as much of a sadist as he is then like yeah that might be hard to do especially since the holy way for this to stick is to chisel your name in his bones like he a statue

Like its hot as fuck that you want to do that to him and he loves being branded as much as the next person but its just not as practical and a lot of effort- which weirdly the fact its a lot of effort intrigues him more

You want mark him that bad? 🥺

Killer craves his name into your skin and its like sinisterly romantic with you willingly letting his darkest urges go ham on you and still loving you always while he gets to brand you on a level that makes him so....giddy in a very fucked up way

Meanwhile once you choose your method he's like a school girl on a date no matter how much you hurt him or how intently you mark him with the most girlish lovestruck giggles as he eggs you on to hold nothing back and just ugh

Her hair being extra long and super floaty

Completely white with a soft cyan outline

Ghostly but also angelic

Dusts hallucination of her

Papyrus is like a backwards version of himself, he is still supportive, loving and nagging of his big brother but also encouraging the murder of others. It's the memory of Papyrus but not the spirit of Papyrus- Pap would never be complicit in of any of this but Sans still wants his brother and can't imagine a world without him

In vanilla undertale he can keep his grief from super spiraling

Dust don't got that mental stability anymore, he needs his brother. Papyrus was supportive and sweet. He still is now. Likely a weird way to cope too, like Dust on some level knows its not really Pap but he can pretend. If he pretends Papyrus is still here then he doesn't have to think about how he killed Papyrus

But the thing is even if Papyrus is warped and twisted, Dust knew Papyrus. They were brothers. Brothers annoy each other and witness embarrassing moments. Grief will always do this thing were you view someone more favorably after they die and overlook their flaws, but Papyrus still acts like Papyrus just without his morality.

Dust in this instance killed Yuri before they started dating, he knew her but he didn't know her yet ya know? There were a lot of messy sides to Yuri he had yet to witness and given Yuri in her last moments- confessed her love to him. Like....Dust has a very idealized version of Yuri whenever he sees her. She's far more graceful. Put together and knowing.

Playful but like in a very gentle way

Kind but way too kind

Y'know? It's Yuri if you sanded the edges off her, Dust has basically built her up as this perfect women due to immense grief, guilt and genuine love for a girl he wasn't super familiar with. He still loves her. But can't let go.

Yuri unlike Papyrus doesn't encourage his murder but doesn't tell him not do them either....her phantom just reminds him to take care of himself....

Its something Yuri would do

Do they talk about how they broke their respective sans

"He joined me on my genocide run!"

"Well I didnt hack the damn game to turn mine crazy- yours dont count"

Cross does not like Nightmare and doesn't trust him but reluctantly loyal to him to an extent

Horror is surprisingly very neutral on him- partly because of Aliza and largely because he is basically the only one that Nightmare is not actively screwing over (Horror just wanted food, shelter & a second chance for Aliza all of which he has gotten). Horror knows he's not a good guy but well- neither is he
