Uncommon Bnha Omegaverse Headcanons
[Long post]
First off I’d like to say I’m not exactly sure what is agreed on for the deltas and sigma's? So any hard facts about them is greatly appreciated. I’m pretty well educated on the regular Alpha/Beta/Omega but these will include Alpha/Gamma/Delta/Beta/Sigma/Omega (?) we’re gonna go with that order
First off lets go through what is what
Alpha’s - Dominate, protective, Go through ruts and can Impregnate Sigma’s, Omega’s, and sometime Betas. They tend to be leaders and can induce heats in Omegas and a sometimes induce ruts. They can’t 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 Omega’s and Sigma’s heats. Can scent things.
Gamma’s - Submissive, Protective but more patient, Go through ruts but more aren’t as aggressive. They don’t like fighting as much and would much rather love on everyone then fight. they’re 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. Aren’t affected by Omega’s and Sigma’s heats and don’t induce Heats or ruts. They can’t get pregnant. [Female Gammas have a retractable pennies and external female organs (breasts and such)] They can also mark Omegas and Sigma's with retractable fangs and form a bond. They also have knots. Can scent things.
Delta’s - 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 Beta’s but can’t induce heats or ruts. Aren’t affected by Omega’s and Sigma’s heats. They get on Alphas nerves a lot but are second to Alpha’s and around the same placements as Gamma’s. 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. Can’t mark/bound with anyone and males don’t have knots.
Beta’s - Natural, Level headed, and Patient. Don’t go through heats or ruts and females have a regular menstrual cycle. Males can only impregnate other Deltas or Betas and can’t get pregnant. Females can only get pregnant by Deltas or Betas (that have a dick) and can’t impregnate others. Can’t mark/bound with anyone and males don’t have knots. They don’t have scent glands and are scent blind, but have a faint scent.
Sigma’s - Aggressive, releases fear in alphas while calming Omegas. Biological have the same body as Omegas and are just as weak. Don’t 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.
Omega’s - 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 and Males have internal organs that allow them to get pregnant. They are weaker then Alphas and tend to avoid conflict. Can produce slick. They have scent glands and can bound and be marked by Alphas & Gammas. Can scent things.

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
They’re 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 he’s in his heat but he did nest after he got kidnaped [It had a lot of Karishma’s scent in it along with Mina’s, Kaminari’s, Sero’s, and one piece from Deku]
Yes, Omega heats sync up and yes 4 omega’s 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 it
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 often
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 doesn’t like the fact he’s not an Alpha but likes that he’s not an omega
There’s 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
