I know that in some omegaverse they have LGBT identities but I hadn’t seen people talk about the T. If say someone was born assigned one sex like Female or Male. But once they are older can they still do surgery like for trans men to get top surgery to make them look masculine. Even is hormonal therapy still works like testosterone shots or for trans women it would the estrone pill.

If they are still possible then dose that mean that someone can even switch their secondary sex? If not then If say I write an omegaverse featuring a trans man dose their omegas identity still effect their overall outlook on masculinity and if an omegas want to appear more masculine would mean they wear alpha perfumes and or take other supplements to hide their omega identity?

you're in luck, because even if you could of course always write whatever you want anyway, omegaverse absolutely can and does feature trans people of all kinds!

there's no reason trans people as they exist irl shouldn't exist in omegaverse, and the same goes for hrt and gender-affirming surgeries (provided we're in a modern setting of course).

now, having a secondary sex/gender does complicate things as some expectations and characteristics overlap, but in general, there also is no reason why there shouldn't be people who'd like to trans that secondary gender and why they wouldn't be able to do it. I've talked a bit about it before. there are the options of bitching and studding, which aren't usually used as a form of transitioning in the traditional sense, but absolutely can and have been used for that in fics I've read. I've also mentioned it as an option for betas here.

but let's talk about it a bit more in depth!

on the biological side, the primary sex is generally determined by one's chromosomes, and has an influence on the testosterone/estrogen levels. it depends on the omegaverse, but this still often has some influence on the genital situation regardless of the secondary sex, and determines whether or not a given person grows breasts upon entering puberty. the secondary sex on the other hand is also genetic, but usually caused by something other than chromosomes (rarely actually specified), and correlates to the levels of alpha/omega hormones of a person. it influences the scent, instincts, the genital situation (again to what extent depends on the exact story), and inner organs that may determine whether the person can carry or sire a child, or both.

on a societal level, these two categories tend to be much more intertwined. as omegas usually get given the role of women in our society, it leaves a big hole where our usual understanding of gender and gender roles go, and shifts the focus towards the alpha/beta/omega divide instead, often leaving unclear what exactly the differences in expectations are for men vs women.

for example, in many stories clothing is split among the primary gender line, so it's women of any secondary gender who usually wear skirts, dresses, high heels, and other similarly feminine things. which you could argue makes some sense, as you'd need to dress children as well, who won't know yet what they'll be. but in other stories, male omegas will also wear such clothing and be subject to beauty standards women are held to like shaving their legs. which does also make some sense, as all omegas would be pushed into appealing to alphas. the line is always where the author wants it to be, and quite often it's rather blurred.

this leaves potential trans characters with even more of a mess of feelings they have to sort out, and even more potential hurdles they have to face, especially when they're young. if a child expresses they'd rather be something they're currently not, adults might perceive it as the little girl likely presenting as an alpha, or the little boy likely presenting as an omega. if an alpha or omega feels dysphoric after presenting, especially if they'd like to trans their secondary gender to beta, that might just get chalked up to everyone being slightly uncomfortable or overwhelmed when they first present and get all these new instincts that weren't there before.

realistically any omegaverse society should have six separate gender identities each with their own standards and expression, that of course all influence one another and are more or less valued by society. so 'masculinity' and 'femininity' would still exist as concepts, but would be perceived and expressed very differently based on whether one is an alpha, beta, or omega.

so taking your example of a trans man who is an omega wanting to appear more masculine - if they simply wanted to appear as a man, they could take testosterone and try to emulate something associated with masculinity regardless of secondary gender (short hair for example is often standard for all men), and maybe get top surgery. suppressing their omega scent or taking alpha hormones wouldn't actually result in them being perceived as more 'masculine', but it would shift the perception to them being seen as a beta or even alpha if they smell like one, which would likely be tied to some stuff we perceive as masculine, like dominance, leadership and the like. if that was what they truly wanted, they'd likely be seen as a trans alpha rather than a trans man. though of course they could also be both. any trans person would have to figure out which part(s) matter to them and what combination would actually make them feel the most comfortable. if any do. there's also always the possibility of agender people or people who'd rather be multiple things at once or something new entirely.

what do YOU think a beta would smell like?

Also- who do relationships between Beta/Alpha. And Beta/Omega. Look like?

indeed. it depends on the story - sometimes betas have no scent, which presumably means they just smell like what real humans smell like. but sometimes they do have unique scents, and while it can vary what exactly the range for beta scents is, it's usually something neutral. nothing sweet, that's for omegas, and nothing sharp that would overpower other scents either. something like amber, or grass. I've used rice before which I like because it's a nice, homely scent that still very much isn't meant to be the main appeal of any meal, you could use bread just as well. when I decide scents for my betas, I just pick something simple I associate with them and go with that.

now, relationships. obviously the details heavily depend on who the people in the relationship are, but I think a beta entering into a relationship with an alpha or omega will always have to grapple with the fact that they're not really made for that. society as a whole will generally look at them and think their partner could've done better, that they're not able to ever fully satisfy them, and maybe even oppose their relationship altogether.

and there is some truth to that, which makes it worse. now, it could be softened if it was a female beta with an alpha, or a male beta with an omega, as they may still be able to have children. but even then, a male beta can't knot, and a female beta won't go into heat and might end up hurt if the rutting alpha just follows their instincts. even aside from the sexual stuff, alpha scents can often calm down omegas in distress, and omega scents can calm down alphas when they get too aggressive, neither of which a beta partner can do.

betas also can't form mating bonds in many stories (though in some they can, so if you don't want them to have this extra hurdle, you can remove it), which means they're also taking this opportunity away from the alpha/omega they date, and the alpha/omega will always smell single to others.

depending on your society, plenty of man-made barriers could also exist. for example, betas may not be able to take paid leave for their partner's rut or heat unless they are married. perhaps it's not even possible for them to marry their partner. the more restrictive the society the more there are likely to be - say an omega can only access birth control with permission from their alpha, then an omega with a beta partner can't access it at all.

i'm new to the omegaverse, so i was wondering, when i was doing research, do omegas have both a penis AND a vag? i've seen this on a few omegaverse guides, and i'm kinda confused on this.

hello dear anon, and welcome!

I've talked about this before on my basic post on omegas, as well as on how they get pregnant

but to make it short, well, this depends on the author's taste. male omegas may have both a penis and a vagina, they may have only a penis but an asshole that self-lubricates and loosens itself when the omega is turned on, they may have only a pussy, or they have some new and inventive shit going on like a second hole beneath their asshole that looks like a second asshole but is functionally a vagina. so it will vary between stories, but it's only one of these options in any one story. some of us like boypussy and some of us are into anal, that's really what it boils down to lmao

Anyways, I have a question that I haven't been able to parse out (I know that you can do literally whatever you want but still): for Alpha Ruts, how does knotting work?

Like ruts are, as far as I understand them, similar to an Omega's Heat, but what they need to do is easier to grasp (An Omega needs to be "filled up"), but Alphas generally want to knot; do knots happen every time an alpha ejaculates during their Ruts? If not, does the knot stay for long periods of time? The popular consensus seems to be that Alphas can't control themselves but what would it look like to try to? They get aggressive?

hi! welcome to the omegaverse, hope you have fun with it!

as is the case a lot of the time, there really is no one clear answer to your question. a lot of it is really just up to the author's preferences or what fits the story, so you'll see it done differently across stories, with nobody being right or wrong.

ruts tend to have more variety than heats in general, some omegaverse stories don't even have them! while heats are basically always assumed. though in my own experience these days ruts are almost just as common as heats, so that's an interesting evolution over time.

as for knotting, that varies too. most commonly, I've seen alphas knotting whenever they orgasm during a rut, and usually also outside of rut if they're with an omega in heat and that didn't trigger their rut, while outside of these circumstances knots rarely if ever happen. sometimes the knot is triggered not by the rut at all but purely by being around an omega in heat, though that's rarer. the average duration seems to be about 15-20 minutes, though it can be longer - usually, if it goes far beyond that, the alpha will orgasm and ejaculate multiple times with just one knot. most of the time, the knot really isn't something they can control, it just happens, so the only way to stop themselves from knotting their partner they have is the pull out method (frequently unsuccesful when in rut because they get caught up in the moment and forget).

How would that even work if alpha×alpha couples don't produce and omega×omega couples don't produce? Or maybe they can produce and it adds to the rarity of the "purebreds"?

If it is alpha×alpha / omega×omega to make a purebred, would bitching/studding be more common or would purebreds be unethical?

well, the answer to essentially all of your questions is, that depends heavily on your worldbuilding

first off, it is entirely possible that alphas can't give birth and omegas can't sire children no matter what, in which case purebreeds are impossible and don't exist.

even if it's technically possible but difficult, while they would be rare, this could lead to purebreds being seen as superior, but it could just as easily lead to them and their parents to be shunned by society as the norm would still be alpha/omega relationships.

there are stories where alphas usually marry alphas and omegas usually marry omegas - there's actually a whole anime with that premise - but that usually means that there are little to no troubles with conception.

in order for purebreds to matter, there'd likely need to be some kind of benefit to make it a widespread, long-lasting desire to have them. it could be as simple as an alpha/alpha couple always having alpha children, so it could be a thing royalty tries to do to ensure alpha heirs, though they'd likely still have omegas around to give them some kind of heir should the attempts for the purebred children fail

as for bitching/studding, assuming that's possible, it might have an influence? perhaps if a bitched alpha is still more likely to sire children than an omega but will only produce omega children with another omega, that could be a way to get the purebreds if one wanted them, same for studded omegas still being able to carry children more reliably than female alphas. but while it might make these more common, the fact that they had to be bitched/studded might then take away from the "purity" of the offspring...

I think for purebreds to be considered "unethical" there might have to be some downsides, perhaps risk for the female alpha parent, or risks of the child having issues similar to inbred children. though it might just be scorn of the alpha/alpha or omega/omega relationships that produce these kids, or it could be seen as a problem that the kids will know what they'll be in adult life. in a society where most people won't know what their role will be when they grow up, it could be perceived as a problem to raise children with the expectations of alphas or omegas from when they're born(of course this applies only if couples with the same secondary sex only produce children with their secondary sex).

i'm planning on writing a story and cannot found nowhere that says how do they start theirs lineage. do they appear out of nowhere?

thanks for the help in advance!

hello dear anon!

unfortunately I'm not quite sure what you mean by how do wolves begin.

in omegaverse stories where everyone is alpha/beta/omega, regardless of how much/if at all they're influenced by wolves, the answer to why they're like that is probably evolution/natural selection.

if the story is actually about werewolves, then usually traditional werewolf lore applies, as in, you get to be one by being bitten by another one. and the first werewolf or werewolves have been cursed or afflicted by some kind of magic. in a highly technologically advanced setting, the curse can be swapped out for human experimentation if you so desire. it's also entirely possible for the wolves to simply not know how they originally came to be if they were born like that and their parents and grandparents were all already wolves just like them.

I have a broader question this time! One of my main attractions to the omageverse cinematic universe is the equality between primary genders (men and woman), and how this allows for a femdom story, not only in the bedroom, but also in a social aspect. Since thats a kink I rlly like to write, omegaverse allows me to run havoc with it LOL! But i know im the minority in this interest. I've done some research and I already know how I want to socially portray my lady alphas in the story, but sex/genitalia-wise, im still a little confused about what would be more satisfying for the readers+me and still make sense lore-wise. A lot of the portrayels, especially in wlw stories, just have the female alphas have penises and the sex was similar to just normal lesbian sex with a strap. I could only find two female alpha/male alpha story (slim picking over here) and it was just like t4t, with one of them also portraying the female alpha as being able to breatfeed the children if she chose to - which i rlly liked! I've seen some cases where writers add additional ways or different ways that female alphas are or look, or how their genitals function, but they were mlm/yaoi, so it was never really explored - just written down on a lore page. And tbh, if I can't see it in action, I can't judge it properly. Initially, I was going for the simple portrayel of just giving them a penis. But maybe I could be more creative? Is something else im missing? I've also rejected the idea of allowing female alpha to get pregnant, it doens't make sense to me to have that but then not giving male omegas the ability to conceive or have testicles. It just seems like double standards to me. I want the female alphas in my story to exhale as much power and strenght as the males, if not more in a individual level, and also do so in the bedroom. Thank you for the help and the service to the community 😼❤️ -🦖

always happy to have you!!

I love to see such enthusiasm for the lore of it all, especially when it comes to female alphas, a tragically underexplored dynamic!

going a bit out of order, I'd agree it feels a bit strange to let female alphas give birth if omega males can't sire children. I have seen either, though usually, these two are connected, either female alphas can give birth and male omegas can sire children, or neither of them can do those things. though even if they can, male omegas usually have trouble trying to get someone else pregnant, as they usually have less cum in general, and what they have is much less potent than what an alpha would have, meaning it likely takes quite a few tries to achieve the pregnancy, even if they were with another omega in heat. female alphas meanwhile, if they can conceive, often have trouble carrying to term, with their bodies often rejecting the fetus like a foreign object. it's really a matter of which set of genders the author wants to emphasize, so if society still puts a lot of weight into whether someone is male or female, it's usually because everyone still has the biological functions they'd have irl, while missing those abilities means the lines fall more naturally to the alpha/beta/omega distinction. since you clearly intend to write a story more towards the latter, it'd absolutely make sense to not have female alphas have the ability to get pregnant.

as for the genital situation, well. you're right that there isn't usually that much thought put into it. most stories don't explore it at all, and if they do, as you say, the most common solution is to just give them a dick.

a lot of omegaverse revolves around big dicks and omegas being really desperate to be filled by said big dicks, so if you choose something else, you'll have to figure out how female alphas can still satisfy an omega in heat - even if the couple you write is two female alphas, the standard is still likely foe them to mate an omega, and if they are lesser partners than male alphas in some respect, that'd likely have an influence on their standing in society as well, so you probably wanna avoid that.

if you're looking for a really creative solution, you might be better off looking at monsterfucking fics than omegaverse ones. genitals come in all shapes and sizes over there. if that's a bit too out there for you or doesn't seem fitting for your otherwise human characters, I could see female alphas having a similar situation to female hyenas going on - their clit is so large it's basically a penis, and the lips of their vulva are closed (which allows them to be penetrated only when they want to).

that would also deal with one of the major problems that come with really drawing the lines across the alpha/beta/omega differences while still having male/female categories - if male omegas have (exclusively) pussies, and/or female alphas have (exclusively) dicks, what exactly makes them male or female? especially at birth, before you'd get differences like boobs or adam's apples? if both of them have both sets of genitals, wouldn't people know they'd grow up to either be a female alpha or male omega? how would people deicde which promouns to use then?

in regards to female alphas, I have seen them as having their alpha genitals grow inside their bodies and only emerging upon presentation, or having permanently retractable dicks as solutions to this problem. I have not seen the hyena solution of them having what is essentially something like a t-dick, where their clit grows large enough to essentially be a penis (and of course in the omegaverse would have all the functionality of an omegaverse dick, including getting people pregnant and forming knots that irl hyenas and t-dicks do not have but all we can hope to look for is a basis in reality. not like we have more than that for male alphas and omegas), and you can have that happen during puberty so they're no different from omega or beta girls until then. it's also a matter of taste what you wanna do for the balls, if they have those on the inside or grow them during puberty as well. if you wanna take inspiration from hyenas again, their labia is swollen to look like balls, and indeed in human fetuses what grows into the balls is the labia in women so. that's an option I suppose.

all of that ofc is still very much reminiscent of lesbiam sex with a strap, though I'm frankly not sure how to both satisfy the need to fill someone up and put cum in them, while keeping things somewhat human, and not make it some version of stick something cylinder shaped into the available hole...

eyyyyyyy look at all the tags that just got canonized on ao3!!!

in addition, could the alpha then offer the omega a worn hoodie to smell and provide comfort?

well if i’d literally scrolled down once on your page and read anything, i would’ve answered that first question about scent patches wearing off so nevermind on that part 😅

lmao you're good dw

I will eventually get around to making a masterpost so y'all can check easily whether something has already been asked or not trust

but yeah a scent patch could easily wear off during a flight!

as for the hoodie, I think this depends, like do they already know each other or is this just some random alpha sitting next to them? because if a stranger starts taking their clothes off next to you on a flight, I feel that might actually lead to more nervousness 😂 but regardless, lore on how alpha scents influence omegas varies - but usually to get that calming effect, the scent should at least be familiar, and in some stories it will only work between mates or pack. strange alphas rarely make omegas feel safe, if anything, they generally tend to feel more like threats. though obviously it could be however you like in your story, just gotta specify that it does indeed work lmao

thank you!!

I've answered a similar ask here, which does go a bit into prime alphas as well as any other dynamic outside the main three that I'm aware of

but as you notice, there's no mention of golden omegas in there, because your ask was the first time I heard that term. there does seem to be a book series that gives (some?) omegas golden-hued blood but that'd require me to pay money to read straight omegaverse and I'm simply not doing that so we'll have to keep living with the question of whether or not that's even related to your question. I'm sure you didn't just make that up, but at least I can confidently tell you it's not a widespread trope, it might just be a term one author liked or something spread around in a specific fandom - frankly, I don't know, and my research has turned up nothing but that one book series and ads for omega3 pills, so... sorry ^^;

you, dear anon, are asking brave questions treading largely unexplored territory.

female alphas in general... usually exist, but rarely have anything about them explained in any amount of detail, especially their genital situation, which does tend to be somewhat important to the bitching process.

(for anyone confused about bitching, I made a post about it here)

in general though, it should work roughly the same as with male alphas. most fics I've seen seem to assume a mixed genital situation, as in, the female alphas will have both a pussy and a dick, often with their dicks being shorter than those of male alphas, sometimes making up for that with more girth. then all you have to do is make one female alpha shove her dick into the pussy of the other one, possibly knot and mate her, and you're good to go! this might even be easier for the bitched girl alpha than for a male one, if she already had the biology to give birth to children (which is probably around a 50/50 on whether she could do that beforehand or not. no consensus has been reached).

you could try to make it work somehow without them having dicks? but then you'd first need to figure out how they sire children in general, and then use that process for bitching as well, though I'm not sure what that'd look like.

absolutely, yeah.

(quick disclaimer obviously nothing is ever set in stone in the omegaverse and any author can always choose to go against what's established as common tropes. but with that being said...)

omegas nest to have a safe, comfortable space for themselves, especially when they're at their most vulnerable - aka in heat. it's where they retreat to when they're hurt, whether physically or emotionally, and being allowed into it is often a great sign of trust. it's why in many stories, alphas ask first before entering an omega's nest, even when irl you wouldn't have any such cultural notion towards someone's bed, especially not if you intend to sleep with them.

pregnancy, much like a heat, also leaves the omega vulnerable, in pain, and generally uncomfortable, so even if they don't always have a nest (in some stories omegas always sleep in nests, while in others they only get the urge to build one when they're in pre-heat and then take it apart once it all got drenched in all the fluids they produced douring the heat), especially later in the pregnancy they'll likely feel better in a nest.

then there's also the fact that outside of modern times, the nest would've been the place where an omega gives birth. doctors/midwives used to go to people's homes to help them give birth, and where else would it be inside the home if not in the nest? though in most modern stories, the birthing is still happening in hospitals - comfort aside, that's just the safest way to do it, and it has the added bonus that the nest stays clean from the fluids the omega loses during birth. I've seen a few times that omegas take some comfort items with them to the hospital, but usually the alpha's presence is enough.

and of course, the nest then has to be built and ready, because after birth, the omega will have one (or more) newborn pup, who needs to be safe and comfortable, and the omega won't have any energy to build the nest while they're still recovering from giving birth, so it's gotta be done beforehand while they're still pregnant.

to anyone confused about bitching, click here. I've also briefly touched upon this question in my post about betas becoming omegas where I said this:

bitching usually is something an alpha does to another alpha. it’s rarely ever used on betas, though mostly because the appeal is in forcing inborn dominance out of someone, which really doesn’t apply to an alpha bitching a beta. still, if you’re into it - maybe the appeal can be making someone regular so horny they become an omega? - there really isn’t a reason why betas couldn’t be bitched

so you're correct, anon, bitching isn't usually for betas. depending on the story, it may be impossible for a beta to be bitched, even if it is possible for alphas. it's certainly not a popular trope.

Thank you in advance, your page has helped me a ton!

I've touched on it before, but never in-depth!

let's start with scent patches, which, as the name basically already says, are little patches one can buy (assuming a modern world, of course) that entirely block the user's scent, making it impossible to discern whether they're an alpha, beta, or omega. in stories where betas have no scent, this will make others assume the user is a beta so long as they don't see the patch. it can also be used to then apply alpha or omega perfume (again, really just a perfume that smells like alphas or omegas) to disguise oneself as the dynamic of the applied scent.

in some stories, certain situations require scent patches, usually in a world where society strives for equality - think job interviews to avoid discrimination, or professional sports, where a millisecond of hesitation because of an opposing alpha's aggressive scent could cost you the game. though their existence can just as well be used to discriminate - usually by requiring omegas, and only omegas, to wear them in the workplace or whatever other situation the characters have going on, and blaming them for any sexual harrassment they experience if they weren't wearing any.

most often, scent patches are applied directly to the scent gland, and thus physically block the scent from coming out. this is easy if there's only one scent gland (often located somewhere around the neck), but more troublesome if there's more. I've seen up to six - one on each side of the neck, one on each wrist, and one on each inner thigh. they can also work similarly to how real medications applied by patches work, though, in which case you can put them on any area of your skin, where they will then release hormones over the time of being worn, which stops the body from producing a scent. in this case, how many, if any, scent glands one has becomes irrelevant.

all scent patches generally share one trait - they do not last forever. how long varies on the story, I've seen it anywhere from a few hours to around a week. they also usually struggle and eventually fail to contain the scent of a heat or rut. the scent is too strong to be blocked, and the body going into heat/rut will be juiced up on those hormones, so it will produce that scent to attract mates and it can't be argued with.

prices and availability vary, though more often than not most omegas in society will be able to afford and apply them. most of the time, scent patches are relatively harmless, even if they often make the user feel uncomfortable, as it's just strange to suddenly not be surrounded by your own scent, even when you weren't actively taking notice of it. they can, however, have some adverse effects if used continuously if the author so chooses. this usually means stunting the scent production permanently. they can also in some stories lose their effect if used to much - the body will get used to them, and you'd need more/a higher dosage to achieve the desired effect. though all of this is optional, sometimes they are perfectly safe to use however much you want.

as for suppressants, let's quickly talk about scent suppressants, which essentially have the same effect as scent patches, but you take them as pills rather than applying a patch somewhere. they too make sure the body stops producing a scent, and will usually also fail during heats/ruts. they're also slightly more likely to have adverse affects or be prescription-only, though again, they're often widely available and overall harmless.

now, suppressants most often refer specifically to heat/rut suppressants. they're pills taken either regularly every day, or right before the heat/rut hits, to make sure the body won't go into heat or rut. one might still feel slightly uncomfortable, sweaty, or queasy, but generally, this suppresses all major symptoms associated with heats/ruts. it may function as a form of birth control too, but usually it doesn't.

suppressants may be taken simply for convenience' sake, though they may also be required for people wanting to hold a job under capitalism, depending on how often and how severe heat/rut symptoms are. if you need a week off once a year for a heat, it's reasonable companies would be required to give you the time off, but if you need a week every month, then they will likely lobby against such laws as much as they can. even if there are no laws, alphas/omegas might be functionally required to suppress their heats/ruts at least some of the time, as there's always the option to just hire a beta in their stead.

compared to scent patches or suppressants, heat/rut suppressants are much less likely to have no adverse effects. the most common one is failure due to overuse. while it may be perfectly safe to suppress a heat/rut, once you start suppressing all of them, it tends to become a problem. one or two heats/ruts a year is a number I've often seen as recommended numbers of heats to have when using suppressants though this can also vary wildly. in some stories, these suppressants only delay a heat/rut, and it's not healthy to do so more than maybe two weeks. if one doesn't follow these instructions, a lot of the time, the heat/rut will simply happen despite the suppressants. it's a classic trope, usually the omega will have been on suppressants too long, and go into heat unexpectedly with the alpha around, and then plot happens. or porn. possibly both. if an author wants to, there can also be more serious consequences (though these rarely happen and are simply warned about/used as a reason why the character needs to get off the supressants) like permanently stopping heats/ruts, or messing with their reproductive capabilities.

notably, once a heat/rut happens after taking suppressants, whether it broke through them or the suppressants weren't taken anymore, the heat/rut will often be more intense, longer, and sometimes (more) painful than having heats/ruts on a natural cycle, implying the body is still producing the hormones to trigger heat/rut, it's just not releasing them. once it does, it's more of a burden on the body than it would be if they were released on the natural cycle.

other tidbits I've seen about it would be that if there are fated mates, suppressants often fail when meeting the fated mate. I've also seen the notion that someone's first heat/rut shouldn't be suppressed, as doing so has the risk of stunting the development of their secondary gender.

So I was wondering If a pack encountered a rogue omega giving birth , like what would they do ?

Would they off both the pup and the omega

Or would they take the pup and off the omega

Or take both of them

um.

based on your question, I'm assuming we're talking something outside a modern setting? because regardless, in most settings I'd assume most people would do what they can to help? bring them to a hospital or a healer of some kind? like generally speaking people in omegaverse are still people and not wild animals, and people tend to choose kindness when possible.

obviously there could be some kind of circumstance like, there is genuine resource scarcity, or there's war so people have reason to distrust strangers they find randomly... racial tensions of some kind... and even then it'd still be an individual choice by the characters in the pack, because I feel the human instinct is to help the vulnerable when they're right in front of you... even if you don't help why would you kill? not saying they can't do that but like, you're gonna have to find a convincing lore reason for that to be the immediate reaction...
