Dare I ask, what's omegaverse?
oh my god i feel like my kid just came home from school and asked me what sex was.
i ain't a "give you a book and figure it out yourself" kinda mom, so we're doin this. here we go.
omegaverse is a kind of slash fic that imagines a hierarchy similar to what wolves have in which you have the dominant alphas, the neutral betas, and the submissive omegas. the universe imagines that these are biological genders in addition to male and female--known as secondary gender--and thus create a different set of social norms/hierarchy. these additional genders are referred to as "maturation," and become evident ("presentation") around the age of thirteen after having already presented as their primary gender (male or female).
omegaverse is formerly known as a/b/o, which we stopped using because it's too similar to a slur for aboriginal australians, but i thought it was important to note 'cause you'll see it around sometimes.
let me clarify before i continue that they're not werewolves. however, historically, the omegaverse originates from a Supernatural fic in which werewolf dynamics were combined with mpreg. however (and confusing that a bit), in the omegaverse there are packs as family (though this depends on the fic). and on the mpreg note, most omegaverse fic is m/m.
let's get into it with more definitions!
alphas - usually larger physically, aggressive demeanor. dominant. have ruts, in which they are periodically affected by the urge to breed--sometimes this can happen as a response to omegas having being in heat (aka estrus)--more on that later. ruts last (in my experience) 3-7 days, and the alpha cannot control or ignore their rut; the rut additionally makes them even more aggressive than usual. alphas can furthermore command and basically everyone follows the command--though nonverbal commands can sometimes be resisted (more on how they might non-verbally command later). we also uhh... gotta talk about alpha dicks later (see: knotting).
betas - literally just normal fucking people. this is also most people.
omegas - smaller physically, gentle demeanor. submissive and breedable. have heats, in which there is a crazy high chance of pregnancy, and all they want is to be bred and they act kinda stupid (literally like they can't cook or clean or NOTHING). the decisions an omega in heat makes are entirely out of desperation and not to be acted on. at the beginning of a heat, the vaginal walls ache and their body temperature goes up. but first? pre-heat! also about a week long, an omega prepares a nest where they'll feel safe; usually blankets, things that smell like loved ones, clothes, food and water. during pre-heat, omegas are totally cognizant, and may invite an alpha or beta to share their nest for their heat. after a heat, an omega is usually pretty wiped and will eat a lot--this shit expends mad energy.
gamma - pretty rare, but im explaining it anyway because they have neo pronouns??? and it sometimes isn't explained that someone is a gamma it's just assumed from the fact that the author is using ze/zer/zim. but this is a third primary gender in which someone will either mature into a female alpha or a male omega, so since the gender is unknown, they are referred to with ze/zim pronouns before their maturation. they're born with both sets of genitalia and a uterus; so they're infertile if they later present as an alpha, and fertile if they present as an omega.
there are also enigmas (literally once every generation; demeanor and physicality just alphas on steroids). deltas are literally just alphas who can't command. i haven't often encountered gammas, enigmas, or deltas in fics personally.
two of the defining features of the omegaverse are scent glands and knotting.
scent glands - residing in the base of the neck and wrists, the scent glands... well, they smell. omegas smell good, alphas are usually described as having an oppressive smell, betas also smell but it's incredibly subdued. the smell of an alpha is always more evident than others. the smell can attract a mate; closer to an omega's heat, their scent becomes gradually more potent. an alpha's smell can tell others that they're in a rut. alphas can issue a non-verbal command that can be ignored (by some people) via their scent glands.
knotting - alpha dicks have this thing very astutely called the "bulbus glandis" (creative, right), referred to as the knot. it's uhh, it's a knot on the base of their dick. basically, it inflates during sex and locks into the vaginal walls and traps the cum inside for max chance of pregnancy. this by itself is fine, but the best part is that the alpha and whoever get stuck together for a period of time. the period of time varies from fic to fic, but i've seen everywhere from 15 minutes to three hours. tbh it's fucking great, it can be really funny and unhelpful or horrible i hate you get out of me or really sweet depending on the ship dynamic. the knot "deflating" is often referred to as "the knot going down."
here's a purposely shitty example to give you an idea of what this looks like:
"i'm the omega and i'm in heat ahh i'm so horny!" "i'm the alpha and i'm in an uncontrollable rut and this omega smells so good! i'm gonna get this omega pregnant! graaaah! [aggro alpha noises]" [probably pretty kinky sex, 'cause there's d/s dynamics here, but varies from fic to fic] "the alpha came inside me and we have to wait for the knot to go down, aww nuts!" [PREGNANT]
aaaand scene.
