Uncommon Bnha Omegaverse Headcanons
[Long post]
First off Iād like to say Iām not exactly sure what is agreed on for the deltas and sigma's? So any hard facts about them is greatly appreciated. Iām pretty well educated on the regular Alpha/Beta/Omega but these will include Alpha/Gamma/Delta/Beta/Sigma/Omega (?) weāre gonna go with that order
First off lets go through what is what
Alphaās - Dominate, protective, Go through ruts and can Impregnate Sigmaās, Omegaās, and sometime Betas. They tend to be leaders and can induce heats in Omegas and a sometimes induce ruts. They canāt get pregnant. [Female alphas have a retractable pennies and external female organs (breasts and such)] They have scent glands and can smell others scents. They can also mark Omegas and Sigma's with retractable fangs and form a bond. They also have knots. Are affected by Omegaās and Sigmaās heats.Ā Can scent things.
Gammaās - Submissive, Protective but more patient, Go through ruts but more arenāt as aggressive. They donāt like fighting as much and would much rather love on everyone then fight. theyāre not as stubborn and way more gentle. They have a scent and scent glands but have a much harder time picking up on others scents. Arenāt affected by Omegaās and Sigmaās heats and donāt induce Heats or ruts.Ā They canāt get pregnant. [Female Gammas have a retractable pennies and external female organs (breasts and such)]Ā They can also mark Omegas and Sigma's with retractable fangs and form a bond. They also have knots.Ā Can scent things.
Deltaās - Dominate beta, Calming, Just as aggressive as Alphas though. Their body is the same as a Beta (same as a regular human being) their scent is a little more potent then Betaās but canāt induce heats or ruts. Arenāt affected by Omegaās and Sigmaās heats. They get on Alphas nerves a lot but are second to Alphaās and around the same placements as Gammaās. Basically scent blind but their scent is calming to Omegas. Males can rarely get pregnant even if they have the internal organs for it. Males can only impregnate other Deltas or Betas. Canāt mark/bound with anyone and males donāt have knots.Ā
Betaās - Natural, Level headed, and Patient. Donāt go through heats or ruts and females have a regular menstrual cycle. Males can only impregnate other Deltas or Betas and canāt get pregnant. Females can only get pregnant by Deltas or Betas (that have a dick) and canāt impregnate others.Ā Canāt mark/bound with anyone and males donāt have knots. They donāt have scent glands and are scent blind, but have a faint scent.
Sigmaās - Aggressive, releases fear in alphas while calming Omegas. Biological have the same body as Omegas and are just as weak. Donāt need to nest as much as Omegas and heats are easier on them then Omegas. They can get pregnant by Alphas & Gammas. They have scent glands and can bound and be marked by Alphas & Gammas. Males have internal organs that allow them to get pregnant but look like regular Beta/Delta when it comes to their external reproductive organs. They tend to be more dominate but can be Submisive at certain points. Can produce slick. Their Scent can put Alphas into ruts. As children tend to fight Alphas just like Alphas fight with other Alphas. Can scent things.
OmegaāsĀ - Submisive, Tend to be the caretaker. Go through Heats and nesting is a regular in their life that is a need to them. Their heat does affect Alphas and can send them into a rut. Their scent tends to be sweeter andĀ Males have internal organs that allow them to get pregnant. They are weaker then Alphas and tend to avoid conflict. Can produce slick.Ā They have scent glands and can bound and be marked by Alphas & Gammas. Can scent things.

Ā Headcanon Time! [finally]
Aizawa is a beta that knows a lot about second genders and can usually predict someone's second gender before they even present [Yes Present Mic is his Husband and Yes he is a Gamma]
Class 1-A is the first class to have this many Omegas
A lot of people mistake Kaminari of an Omega but dude flips a switch and will provoke Alphas so fast
Theyāre all one big pack with sub groups and all protective of each other and way more protective of the subgroups
Momo and Iida are the more level headed Alphas when it comes to someone hurting their classmates while the other two will go into a blind rage
Scenting each other is a regular occurrence and everyone will do it without blinking an eye
Nests tend to be in their own rooms but every once in a while someone will make a nest in a common place like the living room or hallway and others slowly join in on it
Bakugou only nests when heās in his heat but he did nest after he got kidnaped [It had a lot of Karishmaās scent in it along with Minaās, Kaminariās, Seroās, and one piece from Deku]
Yes, Omega heats sync up and yes 4 omegaās go into heat the first time since they move into the dorms and it did happen at the most inconvent time
Sigma heats sync up too and Kaminari felt closer to his packmates while Bakugou hated itĀ
They all presented in 1st year and everyone slowly figured it out because they decided to make it a guessing game
Everyone who has a scent gland has to take suppressants and get regular check ups, It still lets their heats and ruts run their course but less oftenĀ
They have to learn how to not get affected as much by scents and Commands so if a Villain tries them they can resist
Bakugou doesnāt like the fact heās not an Alpha but likes that heās not an omega
Thereās rarely Omega Hero's [All Might is one but only a few people know that]
Mina has Fought with teachers because they said something that made one of her packmates sad
