this is mainly a UTMV (Undertale Multiverse) blog ✧･*+. the purpose is to share art, ideas, and to interact with people who share the same interests as me. but, overall, i do what i want here.

here's a few frequent tags i use:

#art : any art i didn't make

#utmv : anything regarding undertale AUs, aka the multiverse

#80s reblogs : stuff i've reblogged

#80s art : any art i've made

#others' utmv cooking : other people's (undertale) multiverses. usually world-building, concepts, relationships...

#80s utmv cooking : my own (ut) multiverse and various ideas

#80+x operations : conversations i've had with people over posts or asks

you know those cheeky shorts with ominous words on the back that tumblr loves?

good day/evening/morning/night :x) i have more questions, as always.

so, to start off, do monsters need to brush their teeth? in the carrd it says monster food is typically made by sending mana into plants and then preparing them as usual; so, cooking and baking, and i assume using spices and sugar. also importantly, plants tend to have more carbs than meat, and sugar and carbs are both great for bacteria to start producing an unnecessary amount of acid that attacks the enamel. so, question is, does magic somehow offset that, or what?

that was all actually asked to lead up to this True question... do the pantheon members brush their teeth? are the teeth of one of them more clean than the others'? anyone with cavities or very yellow teeth?

also, i would love to know if any of them have any fucked up teeth going on. abaddon has an underbite, but do we got any rotated teeth, cramming, additional teeth, missing teeth, chipped teeth, etc.? also also... does nightmare even... have... teeth...?

this is probably the most specific question i've gotten yet, and to be honest, it's been kind of fascinatingly difficult to answer. (/pos xD)

my first thought in response to this was "well, do monsters sweat?" and we know that they do — i remember seeing plenty of monsters sweat in the original game, including sans in the genocide route — but on second thought i realized that didn't actually tell us anything about whether or not bacteria affects a monster. and i don't think we actually have much canon info about that, but going by TAU's established rules about how monsters are constructed — essentially just a handful of ash suspended by a bunch of energy and willpower — i think the answer is "it affects them, but not as much as a human." humans, essentially being bags of raw meat, have to basically be moving or bathing nonstop their whole lives to prevent bacteria from ruining their day, but monsters simply don't have much for bacteria to want.

likewise, magic food doesn't typically have a shitload of physical matter to it, either. plants became the popular option because 1: they're easy and fast to make more of and 2: they hold onto their existing matter better than animals do when loaded with mana. that isn't to say that animals have no mana or that plants are immune to matter loss; just more resistant to it due to the rigidity of their cells. monster food is said to never spoil, and that would be why; the mana converts perfectly (and almost immediately) into energy, and there's just barely enough physical matter left over to replace any lost dust. that's not a lot of material for bacteria to detect, let alone do shit with.

so TLDR; i think hygiene is still important for monsters, but... less intensive, let's say. they have to worry more about literal muck and grime than bacteria, usually, unless they regularly do something that gets more bacteria-friendly messes on their clothes. it's difficult for a monster to get stinky unless it's actively rubbing stinky shit on itself. i don't think most monsters would have any need to brush their teeth unless they were eating human food, but even in that case, any existing bacteria would be targeting the food and not the monster — brushing would mostly be to clean anything stuck between the teeth.

TLDR #2: most of the pantheon members probably don't brush their teeth, no. in fact, i think cross and horror are the only monsters who regularly bathe — cross as a comfort thing and horror because his body genuinely needs the maintenance, being, yanno... more meaty. killer keeps himself clean but mostly through spot-cleaning, and dust should clean himself a lot more than he does, but yanno. depression.

(cross definitely also brushes, but yeah, he doesn't technically need to. and whether or not abaddon technically needs to bathe post-Accident is kind of... nebulous... but they'd feel gross if they stopped, so, yanno.)

given that context, i think the condition of most of the pantheon members' teeth are... surprisingly decent, all things considered? the worst that come to mind are horror's teeth; they're not built quite like human teeth, but wear and tear have thinned them and stained them a bit — you can see that in his model, it almost looks like he has "gums", coincidentally in places that would be more difficult to clean. that's just staining. and abaddon does have a little bit of an underbite, yeah, but their teeth should realistically be much worse than they are — they used to be very crooked (enough that it gave them a nasty lisp, and coincidentally made it difficult enough to clean that they ended up with a bunch of cavities), but their parents were very image-obsessed, so baby abaddon ended up with braces (and the corresponding dietary restrictions) for like 3 whole years. that was such an unpleasant experience for them that they got kind of obsessive about oral hygiene after, so as to avoid any further trips to a dentist/orthodontist.

honestly, this is all kind of funny for me to realize? IRL, i'm a big fan of crooked teeth; generally speaking i think they're a lot more charming than hollywood cookie-cutter pearly-whites, and i prefer natural looks in general. but the "worst" that abaddon has got going on (besides the gap between their front teeth, which returned despite their best efforts) is a bit of yellowing due to all the tea they drink — but it's not super noticeable because, again, abaddon is canonically kind of hygiene-obsessed. and even then, teeth (and bones in general) are kind of naturally yellowish, so. ?? who even notices that??

as for nightmare, though — i'm actually glad you asked!

for nightmare's 3D model, there's a specific effect i want to emulate. i saw this for the first time while watching a playthrough of Valle Verde:

when i saw this effect, i absolutely fell in love with it for nightmare.

this is yet another thing i'll have to learn more about textures for before i can accomplish it, though; i still want nightmare's default "smile" to be changeable (and to disappear completely when needed), which is why he's currently muppeting it up in all his WIPS xD

when he's done, the seam where his mouth opens should be invisible, with a smile (or other expressions) just painted on. as for whether or not he has teeth, well... it depends on if he needs them, i guess!

hey, how're you doing? hope you're well.

i scrolled through the mtau tag and saw the thing about secondary sex characteristics in skeletons (both in general and in cross' case): about how they have 'marks' around their eyes which is usually seen as a "female" characteristic for skeletons... that got me super intrigued. i love the thing abt monsters having much freer sex and gender expressions, makes a lot of sense, with the souls and all, but it did get me thinking...

if skeletons can be categorized into seperate sexes at all, then

a) how does that work if they don't have genitalia (just bones)? do they categorize skeletons into male/female/other based on the markings and that's it? so, skeletons would then define sexes not based primarily on genitalia, like humans, but based primarily on eye markings or lack thereof. and in the case of ecto-bodies, because from what i've gathered they can summon genitals with their ecto,

b) you said most monsters are hermaphroditic to begin with; are skeletons one of those? if so, how does sex categorization work in that case? and if they don't have 'both' parts by default, are they just stuck with specific junk that "aligns" with what they'd be categorized as? (so, basically how humans tend to do it)

additional questions: would the last question being correct imply that intersex monsters exist?? additionally, bcs i must ask, can skeletons "choose" what junk they'll have when they summon their ecto bodies, or is that more of a "you get what you got" kinda deal? (the glossary does say that monsters are much more malleable physiologically, because mana and all...)

srry if this is kind of rambly, i guess my point is, i'm loving this and i especiqlly wanna know how cross' transgenderism would work. if monsters as a society are generally very open and less rigorous than humans, and not only that, but also physically much less "black and white" [through some humans' lens]... then what does "being trans" mean for a monster? for a skeleton?

if any of this is spoilers or you don't have it figured out yet feel free to leave it out. but i love that you made cross being trans canon to your story and i'd love to know how you go about the whole cis/transgender concepts based off the rules you've set for your world. i'm super autistic about your autismtic love-project

have a fantastic day. also if i had money i'd give you a bunch. stay safe

wow! i have to say i've been feeling really crummy these past few weeks, so opening tumblr to see this ask really made my day. sorry for the delay in answering it -- you gave me a lot to think about xD

as usual, for a longer ask like this i'll break out the proper formatting:

1: How are skeleton monsters categorized into sexes at birth if (a): they have no visible genitalia and (b): hermaphroditic is default?

Typically, monsters are not gendered for the first few years of their lives -- even if they, like Cross*, are born with "secondary sex" features like "feminine markings". I went over this a bit in another post talking about markings, but most monsters default to "it" (or sometimes "they"**) when uncertain of someone's gender. *Cross is from a very atypical universe, and his dad kind of worships humanity as the standard, hence him being assigned female based on his markings. Such practices are not the norm. Typically, a monster will start experimenting with gender presentation around 4 or 5 years old, depending on their lifespan, and probably decide on something permanent around 8 or 9 -- until such a decision is reached and announced, neutral is default. **For monsters, being "dehumanized" isn't usually a negative thing. It's more typical to use "it" for very un-humanoid monsters like rocks or slimes and "they" for more humanoid ones like goats or skeletons, hence why monsters defaulted to "they" for Frisk and Chara, but might use "it" elsewhere. It's just a cultural thing.

2: (Clarification) Are skeleton monsters hermaphroditic by default?

Yes, in most universes. Some AUs will see monsters in general with more human-aligned sex characteristics, skeletons included.

3: Can skeleton monsters choose what genitalia they will have when forming an ecto body, or are they "stuck" with their default?

First, being able to form and maintain a fullbody ecto construct is more of a boss monster thing than a skeleton monster thing -- it just so happens that in most universes, Sans and Papyrus are the only skeleton monsters left alive, and they are both bosses, yes. I say this to clarify that not all skeletons are bosses by default, so not all skeletons would be able to form full genitals or bodies at all. Second -- most of the time, yes, a mature boss monster will have enough control to choose the genitalia that will form! This depends on the boss and the AU, though; one from one of the more human-aligned AUs mentioned above may not be able to choose, but that isn't really the norm. Most can. It's just a matter of preference... and maybe magical skill and mana production. Ecto can be a bit tricky.

4: Can intersex monsters exist?

The current definition of "intersex" from what I could find, according to the Office of the United Nations High Commissioner for Human Rights, is presenting sex characteristics that "do not fit typical binary notions of male or female bodies". It's more complicated than that, and I'll get into that in a second, but TLDR; in order to be intersex, there must be a binary -- so since most universes don't see monsterkind adhering to a strict binary, in most AUs there would therefore be no intersex monsters. (Not because mixed sex characteristics cannot exist in monsters, but because monsters don't care to differentiate someone because of that.) The complexity I mentioned earlier is this: the difference between "intersex" and "hermaphrodite". Hermaphrodite is basically having a fully functional set of "both" genitals, where intersex is having a mixed set of characteristics that aren't necessarily each capable of reproduction. (Not that the intersex person cannot reproduce, but that they cannot both impregnate someone else and they themselves carry a pregnancy -- just one or the other.) A monster is, by default, capable of both insemination and carrying a pregnancy, so to be intersex would be to imply that they somehow had a SOUL incapable of doing one method of reproduction, which shows up sometimes in some universes but very much isn't the norm. Furthermore, things get more complex here when you consider that monsters don't typically use their genitals for reproduction in the first place -- given that humans base the idea of "sex" (and therefore the concept of being intersex) entirely on genitals, it's difficult to say whether or not a monster could qualify.

5: How does Cross being trans work? How does being trans work for skeletons in general, or even for monsters as a whole?

I covered this a little bit in question 1, but to reiterate: Cross is from a very atypical universe, and his father based a lot of that AU on human customs. Cross' experience with being trans is therefore very similar to what a human would experience -- his father decided he was a woman based on some arbitrary bullshit (in this case, face markings that are typically only seen on female-presenting skeletons), Cross got old enough to realize that was wrong and started fighting it, and despite his dad wanting to throw the mother of all pissy fits to get him to conform, he ultimately had more urgent matters (everything with the X Event) to attend to and therefore Cross "got away with it" long enough to get out of there. As for other monsters, though, it's... different. I don't think most monsters really have the concept of being trans -- the closest are probably ghost monsters, but even then the similarities are mostly allegorical. That's not to say that monsters don't ever transition between genders, just that for them, doing so isn't a big enough deal to even blip the radar; not everyone is right about everything they decide on at 8 or 9 years old, after all, so if later someone decides to start wearing dresses and makeup and go by a different name, that's really the end of it. Everyone switches and moves on. To make a better comparison to the social significance I'm talking about, it's like if someone dressed exclusively in White Girl Fall Fashion for a few years and then suddenly switched to, like, Camo -- people will probably notice that, and some might even ask about it, but ultimately, like, who cares that they're wearing camo now? (For example, I think in a lot of universes Alphys is a trans woman; Toby originally designed her as a man and just added eyelashes to change her design into a woman. I just don't think that would be a big enough blip on anyone's radar to even really be a talking point. Just like -- "Oh yeah, I heard the royal scientist is a woman now. I sure hope her experiment goes well so I can see my family soon!) I think whether or not a monster even knew what "trans" was would probably generally depend on if they were from a Post-Emergence timeline and how long they spent on the surface around humans, or else how deeply that human culture seeped into the Underground via the dump (and how that particular human culture viewed transness.) For example, I don't think Horror or Dust really know much about it (or care), Nightmare knows of it but cares even less than most monsters do, but Killer's crossdressing is a bit more consciously subvertive because he's from Saudi Arabia (which historically does not have the best views towards queer people, to put it gently), and Cross is the only one who has a really "human" view on sex/gender. (Aside from Abaddon now, obviously xD) I think you could maybe consider Killer some flavor of transfemm/genderqueer, but I wouldn't personally know what to label him given that he defaults to masculine pronouns and presentation. But for most skeletons I have to say it's pretty much the same as any other monster; they might change presentation at any time or have any mix of "typical" sex characteristics, but ultimately if they say to call them "he" then you know that's what's correct. And it's not really a huge deal; monsters don't really fixate on that kind of thing.

anyway, i really love getting asks like this, so thank you so much! i'm super flattered that you like my world qwq

*GASPS*

also here's a little hint for who i plan to work on next uwu

Negativity and Death go along🥀🥀

(me trying to offset all the lack of content they have)

Close-ups

OOMF asked for an ecto tutorial so I whipped one up to share with you all! This is just my personal process so keep in mind that it won't work for every artsyle or artist,. Neither is this a "do and don't" sort of thing- Artist's are always evolving and I'm sure I'll look back on this some day and see all the mistakes I made, so don't take this as the only way I will every draw ecto. Also, I am sorry if my handwriting is hard to read here, I tried to make it as clean as I could 😭

barely anyone uses his shapeshifting stuff to make him cute. the thought of every detail of his form being entirely nm’s choice and him choosing to look like a queen in a dress is my everything

Is been a hot minute since I posted sum so here’s this :D

i just wanted to quickly say — things are still pretty tight right now with my bf's little brother staying with him, so while i wouldn't necessarily say i'm in an emergency, if you can afford to toss a couple of dollars my way for groceries/toiletries it would be a huge help qwq
