In omegaverse instead of having a sweet 16 what if we have a more like, coming of age thing ? It can be celebrated on your birthday if you want sure, but it's more a celebration of maturity and development and growth.

Like congratulations on presenting as a beta, here's all your beta family members here to give you gifts and give you hope for the future. Yeah, they'll tell you all about their shared experiences both bad and good about being a beta too don't worry.

I'm sure there are traditional gifts to give as well. Like maybe you're given some sort of how-to guide that covers all sorts of stuff both useful and silly, maybe you're given stuff that's scented by your entire family, maybe you're given your first set of protective clothing to cover scent glands, idk. I'm sure gifts would be different depending on which gender you're presenting as too.

Just some thoughts ig, feel free to add on if you want :3

Scenting headcanons

Basically, it's a term that people use to rub scent gland on others or nuzzle up against other person's gland.

Because there is a scent gland on the wrist, if people hold hands to greet, there is a possibility of accidental touching it, so greetings usually only nod.

In close relationships, they grab each other's wrists and shake them lightly.

Don't flirt with anyone who is certain that someone has intentionally been scenting.

It's very instinctive to scenting someone people think they're close to, so usually people like physical affection more than b.h..

Alphas have a stronger dominant tendency, the stronger the desire to scenting.

Unconsent scenting is usually classified as sexual harassment.

The act of scenting a close person creates a comfortable feeling for both themselves and the other person.

etc etc

Headcannons about ABO dynamics's Evolution during history? Something that really fascinantes me about the omegaverse is the biological aspect of It and the Evolution that the 'secondary sexes and dynamics may have experienced over the years. Did alphas, omegas and betas exist since the beginning of the human race? Or at first there were only beta men and women and the rest of the dynamics appeared later?

I like to imagine that originally only existed beta men and women, but at some point the human race was at such big risk of becoming extinct that the secondary alpha/omega dynamics appeared as a mechanism to guarantee a higher chance of reproduction. The capacity of impregnating and getting pregnant being independent from the first sex (man or woman) would allow communities to keep growing despite having a lack of men or women, because there would still be a certain percentage of Alpha women/ omega men that can impregnate/be pregnant and compensate the lack of biological men and women (If we asume that the possibilities of becoming Alpha, beta and omega are all the same)

happy monday!

I've seen it both ways, I prefer writing the "always been this way" style because honestly it makes it easier for me and i have less questions I have to muddle through in the worldbuilding journey.

Here's some of my considerations -

the beta loving community is strong! making betas = normal humans doesn't normally play well with that crowd. Of course, I never write things or refrain from writing things for the pleasure of other people, but still.

if there was an event that impacted fertility rates like that - what's the point of having betas at all? and beyond that does that mean all alphas men and/or amab? are all omegas women and/or afab?

If not - this turns into sort of two phenomenons, 1. being the hypersexuality and hyper-fertility and 2. this suggests biologically at some point teens might develop the genitalia and secondary sex characteristics normally biologically reserved for the opposite gender. With my very small knowledge of what life is like as an intersex individual, I doubt that society would suddenly jump on this train like it's the bee's knees. What then???

Human evolution moves slowly - there are several vestigial elements that are fading out of the genome everyday - like having wisdom teeth, appendix, and a specific type of ear muscle. What sort of event/situation could spark such a large scale change so quickly (even over hundreds of years)?

If it's an evolution thing, that suggests an in and out group. Who are the out-group and what if they're not too into the whole omegaverse thing? (again looping back to the question of betas). Is the in group then a different specie of human alltogether?

If the purpose of this is to get fertility rates up, logically it wouldn't be the first thing that occured. Polyamory would likely become more popular - especially men with multiple wives unfortunately. The human litter size might get bigger. It would become socially acceptable to have children younger - or maybe menopause would start getting later and later. Maybe both. Having children would also need to become a lot cheaper - and if your society is quasi-modern, people would likely need massive incentives if the situation really was that dire. Nobody wants to have a baby just for that baby to have to experience the end of the world.

Regardless of all these considerations above, for anyone interested in developing their own omegaverse rules - do consider a punnet square. If you don't just want to have alphas and omegas, there needs to be some combination of their genes that leads to a beta - or they'll simply cease to exist.

Fertility/population is a tricky thing to use as a fantasy mechanism because in the real world, declining birth rates can't usually be attributed to one single thing - normally it's a multitude of factors converging on one another. Of course, this is inherently a fantastical genre which gives us all the freedom to play and have a little fun making stuff up along the way.

When I was in my teens, I used to make an entire magic system with 360+ unique spells, ordered in magic schools and categories, and it boggles my mind that I basically reinvented DnD mechanics, even down to metamagic.

I wanted to make a wiki about it but I don't have time for it.

The point was to try to encompass every "superpower" I could think of into a magic system.

I even got lore related to it all, I'm pretty sure I'm gonna simply reuse it all for OC worldbuilding. Ngl the fun part was naming all the spells, symbols and coming up with the logic of it all.

Don’t look at me!

Hey I dont know if you're still around, but my friend loved your Alpha Peeves post and was wondering about your ideas for Omega Pet Peeves?

Sure I do!

20 Omega Pet Peeves

1. “No I’m not acting like this because I’m almost in heat, though if you say that again, I’ll tear into like I was”

2. “Well, I saw this one coming, this is the part where I’m told it’s my fault for __________ because I’m an omega?”

3. “No it’s fine really, I can do it, I don’t need to get an Alpha to help.”

4. “Did you seriously just tell me I smelled like heat, as if I don’t already know that.”

5. “I’ll dress how I want, I don’t care if AlPhAs don’t like it.”

6. “I was just asking if you were okay? You smelled distressed. No need to get all high and mighty alpha.”

7. “Of course Omegas can date other Omegas.”

8. “Yeah I’m dating a Beta, no I don’t need an Alpha.”

9. “Yeah ________ really is my job. How do you think I feel in an Alpha dominated profession?”

10. “If I had a dime for every time I got catcalled by an alpha I’d be too rich to walk anywhere.”

11. “Please stop trying to set me up with Alphas because your think they’ll make me more calm/submissive/relaxed.”

12. *deep sigh* “Actually I’m an adult.”

13. “I’m an Omega, not a moron.”

14. “I hate wearing collars. I know Alphas know better than to bite random Omegas necks.”

15. “Actually I don’t want kids” ... “No, I don’t think I’ll change my mind.”

16. “I’m really happy not being mated, I don’t want a mate.” ... “No, I don’t think I’ll change my mind.”

17. ”I’m not made of glass, treat me like you would a Beta/Alpha”

18. “Actually, my mate is very supportive of my independence.”

19. “I’m not teasing anybody, I’m wearing f*cking shorts (dress, etc.)

20. I think at some point it just becomes convenient for people to accuse Omegas of _______________ honestly.”

I think this Venom vs Carnage fight really exemplifies how I think Alphas would fight in my setting.

Since Alpha/Beta/Omega in my setting an extra appendage on their back called an Akashi (meaning “red limb”) that gets ejected out of their backs ( like Kagunes from Tokyo Ghoul), that takes a different form depending on which dynamic you are. I already made a post about Alphas Akashi called the Bukishi (meaning “weapon limb”) here.

But the gist of it is that Alphas can shape the Akashi into any form they desire much like how the carnage symbiote forms different weapons out of his limbs. So I feel the way Carnage fights Venom is very similar to how Alphas would fight.
