Introduction
What is Omegaverse?
Omegaverse is an AU (alternate universe) in this system, there are three main roles: Alpha, Beta, and Omega. So, in a way, you have two genders the male/female gender and the Alpha, Beta, Omega. Also, males can get pregnant.
Alpha
Alphas are the more aggressive ones out of everyone. They are larger and stronger. They dominate in everything they do (yes, in bed too). They have very keen senses. They are possessive of their mates and aren't afraid to show it.
Betas
Betas are the normal, everyday guy. They can still breed with other Betas and Omegas. They are not as aggressive as an alpha and are not as easily affected by an omegas scent, but even betas have a breaking point. Betas can get aggressive if mated or instigated.
Omegas
Omegas are the softer and gentler of these roles. All Omegas go through heats. During this time, they are most fertile. Omegas are the smaller ones with less muscle and are usually smaller in stature. They love to take care of children and all that parenting stuff.
What is heat?
Heat is similar to menstruation. It happens once a month and last for about ten days. It's the time when the omega is most fertile and ready to mate. During these heats, the hormones in an omega go all crazy; they are taken over with a very powerful urge to mate and can be painful for the omega. This is the time they are very susceptible to an alphas scent. A strong scent is released during the heats, causing the alphas to smell it and seek out the omega. If an omega has no mate it would be dangerous to even leave the house. They could get raped and forced into becoming mates with an alpha they don't care for. Omegas in heat will usually stay home where they are safe or will take suppressants to delay their heats to once every other month.
Rut
Is an alphas version of heat. Alphas are usually more aggressive and dominant than they normally are during this time. They are also highly aroused and will look for a mate (unmated betas/omegas). Ruts happen twice a year but can be triggered by an omega in heat.
Slick
Is a self-lubricant produced by omegas when they are in heat to help with intercourse. Slick smell and taste will vary between omegas but is usually sweet in scent and taste.
Knot
Is when the base of an alphas penis swells effectively locking them during intercourse ensuring pregnancy. Most effective with Alpha-Omega pairings.
Scent glands
Are glands that are found in all second genders alpha, betas, and omegas. They are usually located on the wrists, crook of the neck close to the collar bones and the nape of the neck. Scent glands are also a way to communicate how a person is feeling whether they are scared, anxious, aroused etc. Alphas will use their scent glands to ward off any challenging alphas or subdue an omega.
Marking
Is an action that equivalents marriage. It's where the more dominant sex places a bite on the nape of the neck of the more submissive sex (expl. Alpha-omega, alpha-beta, beta-omega).
Now here are the second genders for class 1-A as follows:
Aizawa sensei: Alpha
Iida Tenya: Alpha Yaoyorouzu Momo: Beta
