If you read a lot of fanfiction, you’ve probably come across the term “Omegaverse.” The Omegaverse is a subgenre in which humans live and behave according to a wolf-like hierarchy of Alphas, Betas, and Omegas. But what exactly does that mean? In this article, we’ll explain everything you need to know about Omegaverse, including what it is, how the hierarchy works, common tropes, and more.

The Omegaverse Explained

The Omegaverse is a popular subgenre in fanfiction and erotic fantasy in which people are born into a hierarchy based on now-debunked wolf pack dynamics. One can be either an Alpha, Beta, or Omega. Alphas are aggressive leaders, Omegas are submissive, and Betas are regular people.

What is the Omegaverse?

1. 
   In Omegaverse, humans live in a hierarchy inspired by wolf pack dynamics. Omegaverse originated in fanfiction spaces, though it has since become a popular subgenre in fantasy and erotic fiction. In it, people are separated into different ranks (Alpha, Beta, and Omega) based on their sexual traits. It’s inspired by the now-debunked wolf pack dominance hierarchies.

   • According to the wolf pack dominance hierarchy, alphas are dominant, betas are neutral, and omegas are submissive. Those traits apply to humans in the Omegaverse. Most often, they apply to romantic and sexual contexts.
   • The Omegaverse is also sometimes known as the A/B/O verse (meaning Alpha, Beta, Omega) or the knotting verse.
   • The Omegaverse was initially associated with m/m relationships but has since expanded to all sexualities. Alphas impregnate their partner, while Omegas get pregnant, regardless of gender.
   • The Omegaverse is a common subgenre of werewolf or shifter romance.

A/B/O Hierarchy

Download Article

1. 
   1
   Alphas are dominant and at the top of the hierarchy. Alphas are the socially and biologically dominant tier in Omegaverse. They’re natural leaders and are often portrayed as protective, aggressive, and strong. They’re very territorial, especially of their mate, and they have strong instincts to mate with Omegas. In most cases, Alphas can impregnate their partners, regardless of their biological sex.

   • Often, Alphas have a commanding “Alpha voice” they can use to compel others to do as they say.
   • When they find their mate, Alphas typically claim them via scent-marking or a physical bond. Alphas are very attracted to the pheromones emitted by Omegas. They sometimes go into a “rut” in which they feel an undeniable urge to reproduce.
   • Alphas often have roles as CEOs or other important figures in society.

   Betas are the base-level tier and function like humans. While Alphas and Betas both have mating instincts, Betas typically function as regular humans. They aren’t driven by their instincts as the other tiers are, and they are usually immune to pheromones. They reproduce like typical humans.

   • Betas are often portrayed as stable and level-headed, as they aren’t driven by biological instincts like Alphas and Omegas.
   • Because they’re pretty normal, Betas are rarely the main characters in Omegaverse stories.
3.

   Omegas are submissive and nurturing. Omegas take on a submissive role in society, and they’re driven by distinct biological cycles known as “heat.” During these cycles, they emit powerful pheromones and feel a strong desire to mate with Alphas. Omegas are highly fertile and can typically become pregnant regardless of their biological sex.

   • Omegas are often the main character in Omegaverse stories, with Alphas being their love interests. Many stories revolve around an Omega finding their fated mate.

Common Omegaverse Tropes

1. 
   1
   Wolf-like behaviors Even though the wolf pack hierarchy has been disproven, the Omegaverse draws a lot of inspiration from it. Characters typically exhibit many wolf-like behaviors, especially in regard to mating. Rut and heat cycles are prominent and allude to the natural cycles in which animals, like wolves, are ready to mate. Characters also fall into one of the categories in the Alpha/Beta/Omega hierarchy, listed above.

   • Characters also often exist in family units known as packs.
2. 
   2
   Pregnancy (including m-preg) The Omegaverse is built around biological roles and mating, so pregnancy is often a key plot element in Omegaverse stories. Originally, Omegaverse was an m/m (male/male) trope, so it often involved m-preg, or male pregnancy. It has since expanded to include all genders and sexualities, so now, all Omegas can become pregnant, regardless of their biological sex or gender identity.
3. 
   3
   Fated mates “Fated mates” is a popular trope in many romantic fantasy stories, including those set in the Omegaverse. Fated mates are two characters who are destined to be together, and their bond is unavoidable. The two characters often recognize each other as mates the instant they meet, though sometimes it clicks for one before the other. In the Omegaverse, fated mates may be drawn to each other’s scent.

   Power imbalance In the Omegaverse, Alphas are dominant and aggressive, while Omegas are submissive and nurturing. The genre explores (and often deconstructs) social and biological hierarchies, so power imbalance is a common theme. This imbalance often heightens the stakes for romance and other plot points, as Omegas are often forced to submit to Alphas.
5.

   Scenting and bonding As mentioned above, characters in the Omegaverse often recognize their mate by their scent. When they meet their mate, they form a permanent physical and emotional bond, which is often established by a bonding bite. After a couple bonds, their scents typically change so that they always smell like each other.

   • Sometimes, when a couple bonds, they can feel each other’s emotions, sense when the other is in distress, and even communicate telepathically.
   • After a couple bonds, they may feel physical pain when they’re away from each other for too long.
   • Because each tier in the A/B/O hierarchy has a different scent, some stories include the concept of “scent blockers,” which allow characters to hide their scent and their status.

History & Origins of the Omegaverse

Download Article

1. 
   1
   Omegaverse officially originated with Supernatural fanfiction in the 2010s. While it’s hard to pinpoint the exact fanfiction that started it all, it’s widely agreed that the Omegaverse and A/B/O dynamics were popularized by Supernatural fanfiction in online spaces like LiveJournal and Archive of Our Own. These stories often featured the Supernatural characters in m/m relationships, as well as werewolves.

   • One Supernatural actor, Jensen Ackles, also starred in the sci-fi drama Dark Angel, in which characters were infused with feline DNA, and females went into heat. This could also have been a source of inspiration for Omegaverse fics.
   • The term “Omegaverse” was commonly used in fanfiction spaces by June 2011. The first known Omegaverse fic outside of the Supernatural fandom was published a month later, as was the first femslash (female/female) Omegaverse story.
   • The Omegaverse has continued to gain popularity and has even begun to appear in published novels as well as fanfiction. In 2018, over 39,000 A/B/O works had been published on AO3, and by 2026, over 300,000 have been published.
2. 2
   Many Omegaverse tropes were popularized as early as the 1960s, however. Though the term Omegaverse wasn’t introduced until the 2010s, many of its most popular tropes had already existed for decades. For example, the mating and heat cycle trope can be found in the “Amok Time” episode of Star Trek, and werewolves have long been a part of pop culture media.

Reactions to the Omegaverse

1. The Omegaverse is a pretty controversial subgenre. People seem to either really love or really hate the Omegaverse. Those in favor of it believe it deconstructs gender roles, normalizes LGBTQ+ genders and relationships, and even provides commentary on oppression. Those against it argue that it reinforces patriarchal values and contributes to rape culture. Here’s what some actual Omegaverse readers had to say:

   • When asked about their opinions on Omegaverse, one Reddit user in the r/AO3 subreddit said, “A lot of the Omegaverse fics I have read act as allegories for an overbearing and unfair patriarchal society, but the protagonist overcomes this in some way.”
   • Another Redditor in the same forum argues, “In those works, biological sex is the end-all-be-all for behavior and sexuality. Alphas, aka men, are biologically driven to mate with Omegas, aka women, and vice versa. Alphas are aggressive and sex driven while Omegas are submissive and need protection. And both sexes have a strong desire to mate for life. It’s weirdly conservative and heteronormative, so throwing this dynamic on same-sex couples comes off like erasure or that the author is not comfortable with homosexual intimacy.”
   • Not everyone finds Omegaverse controversial, however; some just aren’t interested. For example, another Reddit user in the r/AO3 subreddit said, “I feel like this might be a weird answer, but personally I think what turns me off most is just the extreme focus on all the pseudo wolf pack behavior, because it comes off to me like the weird girls in middle school who would roleplay being wolves/werewolves at recess lol.”

Common Questions: Understanding the Omegaverse

How do heat, rut, and bonding dynamics work in Omegaverse?

Relationships in the Omegaverse are inspired by the mating and hormone cycles of real animals, like wolves. Alphas go into a rutting cycle when they’re ready to mate, like male animals. Omegas go into a heat cycle when they’re ready to mate, like female animals. Often, an Alpha and an Omega will form a bond (a permanent link between them) when they mate.

What is an Enigma or Delta in expanded Omegaverse lore?

While Alphas, Betas, and Omegas are the traditional ranks in Omegaverse, some works add new, special ranks, like Enigmas and Deltas. Enigmas are a rare, hyper-dominant tier that ranks even higher than Alphas and possess the ability to impregnate Alphas. Deltas are a rare tier that is ranked just below or at the same level as Alphas, but are generally more cooperative and less aggressive than Alphas.

What are the differences between fanfiction Omegaverse and published romance?

There isn’t a big difference in the way Omegaverse is portrayed in fanfiction versus published romance. However, while fanfiction authors build their stories around an existing universe, authors of original Omegaverse novels must build a world that is entirely their own while also explaining the common tropes of Omegaverse in a way that appeals to a broader audience.
