THE ALPHA/BETA/OMEGA MEME


In our world, sexual roles are commonly defined by genders -- male or female or other, by sexualities -- gay or straight, bi or asexual or in-between. But what if they were defined by something else entirely?

Alpha/Beta/Omegaverse is a fusion of fanfiction tropes and animalistic behavior. In this world, sexual roles are divided into three categories: the Alphas (the dominant, the protective and the aggressive), the Betas (ordinary humans) and the Omegas (submissive, fertile and able to carry children).
RESOURCES:
Fanlore on the Alpha/Beta/Omegaverse
Alphas, Betas and Omegas: A primer.
CONTENT WARNING: Below the cut contains descriptions of animalistic sexual behavior as applied to humans, situations of dubious consent, explicit situations, mpreg, and scenarios of societal oppression. Click with caution!


ROLES:
1 - The Alpha.
* Stereotypically type A personalities.
* Anatomically: Males have a penis; females may have a penis in addition to a vagina.
* Alphas knot their mates, meaning that the base of the penis swells and locks them inside their mate while they produce copious amounts of semen in an effort to breed.
* Strong sense of smell.
* Near an Omega in heat, they experience a compulsion to mate that is almost impossible to overcome.
* Alphas may go into rut, which is their equivalent of Omega heat, and drives them to mate.

2 - The Beta.
* Ordinary human being.
* Males have penises; females have vaginas.
* Can mate to anyone.
* Might be able to smell hormones of Omegas and Alphas, but will not be overwhelmingly affected by them.

3 - The Omega.
* Stereotypically submissive, quiet, intelligent and less physically able.
* Female anatomy is similar to Betas; males are self-lubricating and may have either an external or internal vaginal setup.
* Regularly go into heat, which involves being overcome by the urge to mate. They are unable to consent while in heat.
* May be made compliant by a bite to the neck. However, that may also induce a mating bond.
* Often regarded as second-class citizens or prizes to be won.

SITUATIONS:
1 - Bonding - Love at first sight. You've spotted your soulmate. You can smell them, you can feel them, you know that they'll be with you until the end of your days. Unless there's something between the two of you. It could be age - maybe one of you has to wait until the other has reached maturity. It could be that the bond is one-sided, and the other has yet to fall in love. It could be an unwanted bond, or society could have divided you into different places. Is your love strong enough to conquer?

2 - Heat/Rut - The need is coming on you strong. Everyone for a half-mile around can smell it. Better find someone to ride it out with, or hole yourself up in a room with a few bottles of water and a durable sex toy. And you'd better hope that there isn't someone out there who will take advantage of your pliable state. Best case scenario, there might be a Beta who can take care of you, or fend off anyone too predatory.

3 - Pregnancy - Whether through a heat or not, you're pregnant. Congratulations - or condolences. Is it time to start a family, or time to start panicking?

4 - Suppressants - You're using suppressants to keep yourself on an even hormone cycle, skipping heats, or maybe pretending to pass as a different class of society. After all, Omegas might want to be in the military, where they're not usually allowed - or an Alpha might want to take a job in a university or as a nurse. Shouldn't they be allowed to, if their hormones are suppressed? Just hope that you don't miss a dose.

5 - Mistaken Identity - That friend that you always thought was an Alpha, or an Omega, or a neutral Beta, turns out to be something entirely different, and your world is turned absolutely upside down. Does it challenge your preconceptions? Or does it just ruin the balance between you two?

6 - Unlikely Pairs - After all, there's no actual reason that Alphas have to mate with Omegas. Maybe two Omegas can satisfy each other. Or two Alphas. Or your intended mate could easily be a Beta. Maybe this is just about breaking out of your pre-established role and becoming something new.

7 - Manifestation - In some cases, an individual may not know they are Omega, Beta or Alpha until their first heat/rut/manifestation, usually happening in early teen years. It may take you by surprise; it may be a blessing, or may be a deep disappointment.

8 - Other - Adventures in getting jobs, making families, fighting bad guys, and anything else you can come up with!

[ Info in journal. Fine with whatever designation or combination but he will probably lie about whatever he is or pretend to be something else for reasons (the reasons are he is annoying). Unlikely to be very typical for any classification. ]

[ Omega or 'Serum turned him Alpha, wtf does he does with this. Happy to do gen/world building or PG relationship shit as well as the smut. Not overly interested in pregnancy.

Canon, cross canon, assumed CR.]

Cross-canon with this prince?

Noct can be either alpha or omega, we can say maybe Noct is a prince in the real world and fights alongside the avengers like T'Challa ooor we can say Cap et al live in his kingdom and Cap has known Noctis since he was thawed from the ice. Being the heir to the throne he would definitely know Steve and maybe they have a knight/prince thing going on, either arranged or organic.

If Noct is from Earth I can see it being more organic. Noct can be an omega who does not know what to do with that bc a prince is supposed to be a strong alpha meanwhile Steve is confronting the same issues with his post-serum alpha status. They can talk about it if you are interested in any of these ideas.

[ age ranges 16-26ish so lmk if you got a pref. omega and wildly rumored to be so even if nothing is ever confirmed due to his rock-idol/sometimes model status. suppressants definitely involved (and probably over-used.) ]

[Asa is definitely an Alpha, and normally he would be a very kind and considerate one, probably on suppressants and trying his best... But I'd love to play something where he forgets them or can't help his feelings, etc. Open to anything really.]
akiyamakun: (I'm here with you.)

[personal profile] akiyamakun 2026-02-07 02:13 am (UTC)(link)
[Akiyama here is a perpetually-bored delinquent who would totally be the kind of gremlin Omega that'd "innocently" rile up a struggling Alpha into a state of peak sexual aggression on purpose, for his own amusement... Interested in a scenario where Akiyama does his best to make a nice guy like Asa go feral? :3 ]

( either an omega on all the suppressants so the entire league thinks he’s a beta or an omega with a meticulously managed regimen who is known for pointedly avoiding all alphas and proving through his playing that omegas can fucking do this thank you very much. I am a sucker for surprise heats, and while I’d like to avoid mpreg everything else is on the table )

[personal profile] eidosariste 2026-02-06 04:41 pm (UTC)(link)

(ooc: An alpha who has been taking medication to suppress the onset of rutting. Ideas for how to overcome this include being stranded alone with someone for a period of time where the medication starts to wear off. The other person having such potent pheromones it overpowers the effects of her medication. Or something more sinister like someone swapped out her meds with placebo to set her up or get her with someone. Especially interested in scenarios involving heat/rut and unlikely pairs. I'm not interested in full out non-con but riding that line is fine. Usa will have a fully functional penis with or without the potential for knotting. Kinks such as clothed sex (costumes), inflation, and impregnation are also an option. Castmates would be loved. Open to any cross-canon, cross-medium, and OCs with at least some information available.)

[High-compatibility beta, it's why he's in the line of work he's in, because he can help whoever needs it. He can knot (not as fully as an alpha, but it's still there) and can handle an alpha in rut without having to worry about a bond-bite or a pregnancy taking hold.]

Joe | The Old Guard | OTA

[personal profile] nicely_tousled 2026-02-06 08:32 pm (UTC)(link)
[Either/or, regardless Nicky is his, but that doesn't mean they don't sleep with others sometimes, and there's also a chance that if you take one to bed you're going to get both. Which is to say: if you're interested in both, just let me know, we can wing it.
Also that second movie didn't happen except as someone's nightmare.]

[personal profile] roll_for 2026-02-06 08:33 pm (UTC)(link)

Nicky | The Old Guard | OTA

[personal profile] allandmore 2026-02-06 08:34 pm (UTC)(link)
[Whichever works, but either way Joe is absolutely his. They do sleep with others though, and they do share, so if you're interested in both vs. just Nicky, let me know, we can make it work.
2nd movie was somebody's fever dream, not actual events.]

Chrissy Cunningham + Stranger Things + OTA

[personal profile] cheerybomb 2026-02-06 08:35 pm (UTC)(link)
[Surprise!Alpha, she's been on suppressants disguised as multivitamins since puberty, because Mrs. Cunningham wasn't about to allow any kind of Deviance in her household.
Not interested in pregnancies, Jason, Billy or any of the kids, cross-canon and further AUs are all welcome, if you're not sure just ask!
Also available in male surprise-Omega flavor over at [personal profile] ccunningham]

No Billy, Jason or the kids, please.]

No Robins for any shipping or smut, fine for gen scenarios/family dynamic shit or things being revealed. 30+. No pregnancy plots. Gen stuff as welcome as porn regardless. Canon, Cross-canon, and assumed CR are fine]
