I’D LOVE TOOO

-The easiest part of Nightmare Error can touch is his tentacles- since they don’t feel human and just feel like slime. It’s not a pleasant texture, but it doesn’t feel humanoid at all or warm enough to make Error’s phobia trigger, so Nightmare only touches him with his tentacles if need be.

-They tend to get into really explosive fights- due to each of their coping mechanisms while arguing infuriates the other. Nightmare stays cool and passive aggressive which makes Error more angry and hot headed- which just makes Nightmare annoyed. Stay far away from these two when they are fighting…either Error will start throwing things or Nightmare will kick him out and be in a horrible mood for the rest of the day…

-They apologize with gifts- never words. Error is too prideful and Nightmare has a habit of slowly getting consumed by guilt for getting angry that it makes him feel ashamed. Most of the time, he believes no words will be enough to apologize for simply being mean to Error, so he gives him sweets. Error apologizes with affection or with slight off topic things. He’d come into a room and tell Nightmare he thinks he looks nice, but that’s all Nightmare really gets as an apology. It’s more than enough.

-Error refused to kiss Nightmare after finding out he drank coffee like a madman. He hates the smell and taste and will walk out of the room when he smells it. Nightmare obviously hated that and switched to only having tea- making sure it’s sweet flavored so Error will kiss him more.

-Nightmare fell first. HARD. Error fell for him after Nightmare was constantly there for him and helping him in battles.

-Error knits Nightmare clothing only to test how they look. He knows Nightmare’s goop will ruin them, so Nightmare basically serves as his model for different kinds of outfits. It makes Nightmare very flustered.

-Both have been together for so long that they don’t really celebrate anniversaries bc everyday is a day of happiness when the other is by their side

-Error doesn’t remember how they first met. Nightmare remembers it exactly.

-Error remembers exactly how he asked Nightmare out and is constantly haunted by how he got so nervous he glitched out and stomped on Nightmare’s foot before tumbling off of the side of a floating island in Outertale. Nightmare caught him and when Error came to, Nightmare said yes to going out.

Nightmare does not remember any of this. Error makes sure to keep it that way.

all my monster culture hcs

(may be based in things we see in game, may be random stuff)

monsters’ ages of maturity vary a lot and it’s very difficult to tell what monsters are adults and who are children since there are so many different kinds, that’s why all monster children wear striped shirts.

once a monster child reaches their species’ equivalent of around 16 years in maturity, they have a big, special celebration (like a bar mitzvah or quinceañera in human culture). the main event is the monster’s friends and family gifting them new clothes. for some families, it is tradition to pass on a single garment to the first-born child for generations, although this is not always the case. (for the royal family, it’s asgore’s cape)

when monsters were first sealed behind the barrier, the underground was much smaller than it is in the game. originally, it was just the ruins, snowdin, and a small bit of waterfall. but due to erosion over time and many wanting to mine further to avoid overpopulation, it’s size grew a lot.

all monsters are immortal (in the sense of that they can’t die of old age) until they choose to have children, in which they give up that immortality.

this is done by a soul bond, when two (or more) monsters fuse their souls together and the part of immortality in them leave to form a new one. this can only be done if both monsters want to create a new life, therefore accidental and/or non consensual pregnancy can’t happen.

we know a lot of human stuff has been repurposed for the underground, but a lot of the stuff containing images or videos of actual humans (except for stylised animation) have been confiscated by the royal guard. the government said it was because many monsters could have pstd flashbacks to the war by seeing real humans. this is why many monsters don’t actually know what humans look like.

monsters species that possessed wings live primarily in new home due to its open nature.

education in the underground is usually pretty good. to make things easier on monster students that age faster/slower than their peers due to species, formal education in a standard grade system is not required. in order to become a legal adult, a monster that reaches the age of maturity would have to pass a government-made exam to prove they can function independently.

while new home, the core, and hotland exist in a modern capitalist system that functions as well as it can, waterfall and snowdin operate on a more trade-based economy while maintaining use of g’s.

i’ll probably add more when i think of them, but feel free to add on your own!!

Not to suddenly post undertale headcanons after not for a while but. I had a Thought about monster battles

What if i depicted them like... When a battle starts an actual barrier is created sort of? Like the battle box basically

And in a typical battle it's like this:

So you can freely walk around and dodge to your little heart's content

But when someone hits you with the blue mode, it's like THIS:

So now you can only jump and move side to side or something

If that makes any sense lol

I had to share it because I don't wanna forget what feels like an epic idea rn

[shepscapades]

Surely this will have no negative consequences whatsoever!

[swiftmitsu]

i dunno about you guys,

but I don’t think they like Ink sneaking into their kitchen in the middle of the night

* I-I don't think we were talking about the same thing...

[BEGINNING] [PREVIOUS] [CONTINUE]

[thatsafuckeduptale]

The world put Swap sans and Swapfell sans in different universes because if they were in the same one they'd blow up several buildings because they felt a lil silly.

The world put Swap paps and Swapfell paps in different universes because their anxiety would bounce between them so fast it'd cause a demon core reaction.
