Summary
Error had always been in control of his teleporting abilities. He knew the ins and outs of world-hopping like the back of his hand. The joke was on him, though, because the multiverse didn't play by anybody's rules.
An impulsive decision to teach Nightmare a lesson in respect went horribly wrong. As a result, Error and Nightmare become stranded in a foreign and hostile dimension.
Finding a way out was easier said than done.

Summary
new summary:
A long time ago, a skeleton with black tattoos found themselves alone in a white void, in one story, that skeleton went and became beloved by the multiverse that he protected, but in another, in this multiverse, that skeleton never took that journey, and stayed hidden, avoiding attention, the multiverse remaining unaware of their existence for years and years and years...until someone, dream, noticed.
(old summery:
I always liked the image of ink being a homeless hobo skeleton creature with no sense of shame or social norms, having no idea how to math because they have no actually education and basically clinical insane, I also like to imagine that by following his rule of "don't interfere with the goings on of the multiverse" he would act feral as fuck, So this is exactly what this is, dream and blue basically trying to tame the multiverse guardian ink. but like way more plot based)Series

Summary
“I’m not here to stop you.” He stated flatly, hardly trying to actually convince him.
“Bullshit. Then why are you here?” The dust-covered monster interrogated him, completely done with his sporadic visits. But, instead of receiving a clear answer, he only got a shrug.
“What’s your favorite color?”Series

Summary
The Multiverse is vast and nigh infinite, possibilities, concepts, the very function of a world's reality only limited by sheer creativity.
Within this realm, Dreamtale exists as an enigma, plucked from another Multiverse entirely. The tragedy of it's Story forced to continue beyond it's Endings, for it forced the concept of Balance into the Multiverse's rules. Now open-ended, the only two Characters wanders throughout the Multiverse as one of it's Outcodes.
Dream broke out of stone to one colorful and curious Inkblot, so much to comprehend for someone so small. But alive nonetheless.
Nightmare woke up freshly dead.
Au: Get it? Cuzhe died lmao

The Omega Timeline's Multiversity of Science and Magic by WaterLily1
Fandoms: Undertale (Video Game)
15 Sep 2025
Tags
Summary
The Multiversity- a college run by Core Frisk and their Omega Timeline Council. It welcomes students from across the multiverse, no matter their backgrounds. While there are always some challenging students, this year boasts an exceptionally wide assortment of unique faces. Many of whom are neither thrilled to be there, nor fans of their administrators.
In other words: A college AU featuring all your favorite Sanses. True stories from wild college experiences sprinkled in with general chaos and disaster as skeletons from various backgrounds are shoved together in a classroom setting and given way too much freedom.

Summary
[Y/N] [L/N] is a powerful mage with a bloodline well-known throughout the ages and her family have always been celebrated. They, however, despise how their bloodline trapped monsters beneath the ground. But, that is for another day. In not being able to afford basic accommodation for university, they had to rely on an old (and terrible) friend named Bethany. For some reason, most of Bethany's skeleton mates despise [Y/N] but why is that? Apart from the fact she is a mage?
Just because she has a kindness soul, it doesn't mean she will stand for their bullshit.-

Summary
Sometimes, forgetting everything is for the better...but it’s not like you had much of a choice, you just kinda woke up in a lagoon all by yourself.
No memories, no nothing, just a horrible ache on the side of your skull and a bitter taste in your mouth...
But time heals all wounds....or so they say...

Pan-ghetti-cakes Bring Families Together by PerpetuallyTired_PT
Fandoms: Undertale (Video Game)
05 Nov 2023
Tags
Summary
For the UT character bonanza prompt: Breakfast
Error nearly closes the portal for good to continue working on his puppet to spite his hunger when he finds himself staring as a classic Papyrus stands at the stove. The Papyrus is wearing an apron with “COOL COOK” written on it in sharpie as he cooks what looks to be pancake batter mixed with spaghetti. It shouldn’t be appetizing, and normally Error’s sure it wouldn’t be. Yet for some reason that he’s obvious too, he finds himself reaching through to grab the plate of finished pan-ghetti-cakes sitting to the side.
“AH AH,” Error freezes, confusion and rarely felt shame stirring in him at the scolding tone.Or, Error eats breakfast with two skeletons who feel strangely familiar.

Summary
Nightmare didn’t pay Killer to be nosy, but then again Nightmare didn’t pay Killer at all.
Besides, Killer never really knew when to quit. After a nasty fight with Cross, Killer gets lost in his frustrations and ends up in a part of Nightmare’s castle he’s never been to before.
The deeper he goes the colder it gets, and the darker it gets. The light he finds at the end of this tunnel seems more like someone's prison than a way out.

Bookmark Notes:
Nightmare "the slime" Undertale highly respects Nightmare (the Skeleton) and made an unspecified deal with him. Over 800 years Nightmare the slime takes up the title and duties, which he considers to be spreading negativity as much as possible. He wants Nightmare the OG to wake up to an empire that belongs to him and for him to be safe and comfortable. OG nightmare is inside slime NM for years before OG Nightmare decides he needs to be removed so that his injuries heal. Hes "extracted" which was apparently very dangerous and arduous and then placed into this orb. Slime NM tries to give him good memories but inside the orb OG NM is suffering through a loop remembering what he lost.
The orb is hidden behind a clock in the castle. Killer finds it then Dust finds out what Killers been sneaking around for. It's implied that Killer speaking to the orb did make OG nightmare happy. Slime NM thinks the emotions from Dust and Killer means they're a couple and they're like "good for them i guess."
Anyways they find out that Slime NM is not the original NM and get really unsettled. They fight about whether or not to leave. They sneak around and argue enough that Axe and Cross get upset as well. Eventually NM is cornered next to the secret room and accidentally destroys the orb. NM the OG is freed with some damage but enough to survive.
Everyone's uneasy. Nightmare the Slime is honest but sort of indifferent which doesn't help. Axe and Cross start forming some sort of connection with NM the original gangsta even though he's completely out of it just in it for the soup. Nightmare the slime is pleased that he's making friends.

So there's this Chinese Errorink fancomic. It was canceled by the creator lansidealun. I can't even find it in good quality anymore.
But I really liked their comic, so I 'translated' it into fanfiction form. I also extended it a bit.
It's pretty dark, so trigger warning for anyone sensitive to non-con
this is some pretty shameless smut-
