Lets see all my silly little writing
Alpha (A)
Alphas are (in most cases) able to impregnate Omegas, no matter the primary gender. Alphas are often (but not always) "dominant" in some shape or form; whether it be in size, personality, or actions. Male Alphas have a knot when aroused, and in some worldbuilding, female Alphas are also able to impregnate others; some will temporarily grow a penis to do so, or their vulva will permanently grow into one when they present. Alpha's have strong, more 'masculine' scents and are usually the head of a pack/house. Alphas may be jealous and possessive of their mate (whatever dynamic)
Note: Luna's are the Alpha's/pack leader's partner, and socially have the same power
Gamma's (Γ)
Gammas are socially submissive Alphas; they’re not as stubborn as their counterparts and are usually on the gentler side, but that doesn’t mean sweet Alphas are automatically Gammas. Gammas usually refrain from fighting and other shows of dominance, but don’t hesitate to smother Omegas (or any one else, for that matter) with love. They go into ruts, and have more of a sweeter or calmer smell then alphas
Betas (B)
Betas are usually the right-hand man to the alphas and keepers of the peace between the Alphas and the Omegas. Male Beta's are able to impregnate Omegas, and Alphas may be able to impregnate both male and female betas. They can either go through heats or ruts, both, or neither, and usually have a mild calming scent. They are usually also able to tell when an alpha or an omega is going to go into heat/rut and can sense the smallest changes in emotions from scent. There are of course subtypes, such as:
social-dom betas (presenting much like alphas)
social-sub (presenting more like omegas)
true neutral betas, who don't have much of a scent and don't go through a heat or rut (the closest to a 'normal' human)
Epsilons (E)
Epsilons are the children of Alpha fathers and Beta mothers and are born almost at the same rate as Lotas, if not slightly more due to the usual dominating nature of the alpha. Epsilons are very similar to alpha in strength and scent, but more often go through heat. They are more of an underdog, and they often require cunning thoughts and deeds as well as tricking people to show their dominance. Because of this, Zetas and Epsilons often are found out hanging together as both are seen as 'outcasts'
Lotas (l)
Lotas are one of the rarest and sought-after gender, as they are practically omegas, but with shorter heats, and bigger builds, but just as submissive. They do not nest for comfort or mating, unless it is under peer pressure. Most Lotas these days don't even know they are Lotas though. Lotas are born from an omega 'father' and a beta 'mother' (the one carrying the child)
Thetas (⊙)
Thetas are the most dangerous of them all. No one knows how or for what reasons Thetas are born, but they have a mutation in their calming scent that most betas would have, but the mutation makes their scent much stronger, often strong enough to knock someone out. They are mostly seen as weapons of war more than actual humans, and so they usually have to hide their scents with blockers and suppression, or risk being kidnaped or killed.
Zetas could be seen more like shapeshifters or something of the sort. Some zetas can change their secondary gender at will, or sometimes, it changes over time as they grow up, though most of the time they have no firm presenting gender, though they lean towards something more than others. Zetas can go through heat or rut, or just completely not one.
Delta (Δ)s
Deltas are more like true neutral betas. They don’t provide calming qualities with their scents like Betas do, and furthermore, their scents are almost unnoticeable, but they are almost even more hyper-keen to other people's scents and emotions, and usually work alongside betas in schools and hospitals because of how less affected by pheromones they are. They can go into either heat or rut, though it is usually much shorter.
Sigmas are socially dominant Omegas; they are just as aggressive and dominating as alphas and often pick fights with either one another or with other people. As children, Sigmas and Alphas are hard to tell apart until a sigma goes into heat, but still then might look and present as an alpha. Sigmas are just as physically weak as omegas, as they both share nearly the same biological makeup. Sigmas often tease their Omega friends about their nesting habits, as Sigmas do not nest much outside of heat and pregnancy. Their scents are strongly more like an alpha's, except when in heat, then it could be possibly much more overpowering than an omega's
Omegas (Ω)
Omegas can get pregnant and go into heat. They are generally lowest on the hierarchy and expected to stay home and care for the pups and the home. Male Omegas are self-lubricating and have the ability to become pregnant. Omegas often tend to be smaller and weaker than the other dynamics and are seen as more fragile. They usually have a sweet scent that intensifies around when they are about to go into heat to try and find a mate, which is most often preferred to be alphas, though if an omega is desperate enough, they will also nest with other omegas or sigmas during their heats too. Nesting is quite a big deal to omegas, and them letting you even near their nest is a big sign of trust.
