Omegaverse

Alphas: Some commonalities are that they might be in elevated positions of power, whether their regular social standing or whether they’re put into leadership positions. They’re going to be the more dominant sexual partner in a relationship. Also, they have active control over their scent and can use it to influence others. Alphas take on the role of protector for Omegas, and Alphas, regardless of biological sex, should impregnate their partners, depending on whether they can get pregnant. Omegas: Omegas tend to be viewed as more vulnerable or submissive. They also tend to have less control over their bodies than Alphas. Moreover, they can typically get pregnant regardless of their biological sex or primary gender.

Mating and Reproduction

Omegas become more clingy and needy during estrus. Some people can cope with their heat, while others find it difficult to endure this period without the help of an Alpha. They produce a large number of pheromones, and their scent changes and becomes more seductive and sweet, attracting the attention of the alpha to omega. Also, many omegas have their own special rituals and preferences during estrus. It all depends on the character of the person and their personality. Alphas become more dominant and attention-seeking omegas when their rut begins. They also release their alpha pheromones to show that they are open to mating. In bed, they dominate and claim their omega. Depending on their character, they also do certain things that they prefer the most. Similarly, both Omegas and Alphas have a high libido during the heat. And most of the time they don't think straight, but, again, it all depends on the personality of the person.

Hierarchy and Social Structure

Depending on the setting, an omega imprinted on an alpha becomes more socially and emotionally stable, such as making it easier to control the heat cycle or only being able to smell the omega scent. Usually, once imprinted, the body reacts to prevent sexual intercourse with other people. When an alpha and an omega form a relationship similar to a husband and wife, they acquire various rights socially, and the way to become a mate is for the alpha to bite the nape of the omega during sexual intercourse during heat. The paired alpha and omega only come into heat with each other, and only two of them can conceive and give birth. However, this 'mate' is dissolved when the partner dies.

Scenting and mark

Omegas and Alphas have individual scents. Omegas are sweeter and lighter, Alphas are more tart and musky. During estrus, their scents also change depending on their personality. A mate mark usually means that an Omega has been taken. Depending on the Alpha's wishes, it can be either a temporary or permanent mark. Alphas usually bite their omega in the crook of the neck or in any other place, depending on their preference. The mark contains the smell of alpha, so the smell of omega and alpha is mixed, making it clear that omega has a mate. Also, a marked omega may stop smelling other alphas, and their estrus period may begin to coincide.

Mpreg

Omega male can get pregnant in the same way as omega women. But their pregnancy proceeds somewhat differently from the usual pregnancy.
