    • 2006, Catherine Mann, Blaze of Glory, Harlequin (2006), ?ISBN, unnumbered page:

      “I guess in your psychological language of alpha males and beta males, I would be firmly in the camp that prefers the more laid-back betas,” she took a deep breath, “like your father.”

    • 2010, L. A. Banks, "Dog Tired (of the Drama!)", in Blood Lite II: Overbite (ed. Kevin J. Anderson), Gallery Books (2010), ?ISBN, page 121:

      “They want sexy, virile alpha males, yes? But that doesn't come with sensitive and loyal and all of that. That's a beta. A frickin' collie, Lola. […]

    • 2010, Terry Spear, Wolf Fever, Sourcebooks Casablanca (2010), ?ISBN, page 24:

      She'd always had a thing for alpha males. Not that she had any intention of being bossed around, even if one had her best interests at heart. Her fascination with alphas was that they were a challenge. Betas didn't hold much of an appeal.
13. (fandom slang) In omegaverse fiction, a person of a (usually secondary) gender/sex that mirrors the biology of a normal human, being free from the biological drives of alphas and omegas but generally capable of bonding and mating with either.
    • 2013, Kristina Busse, "Pon Farr, Mpreg, Bonds, and the Rise of the Omegaverse", in Fic: Why Fanfiction Is Taking Over the World (ed. Anne Jamison), page 317:

      Many A/B/O stories posit societies where biological imperatives divide people based on wolf pack hierarchies into sexual dominants (alphas), sexual submissives (omegas), and everyone else (betas).

    • 2017, Marianne Gunderson, "What is an omega? Rewriting sex and gender in omegaverse fanfiction", thesis submitted to the University of Oslo, page 99:

      In ASD, the beta also functions as a contrast, as Yuri is assumed to be a beta before his first heat reveals his omega status.

    • 2018, Laura Campillo Arnaiz, "When the Omega Empath Met the Alpha Doctor: An Analysis of Alpha/Beta/Omega Dynamics in the Hannibal Fandom", in The Darker Side of Slash Fan Fiction (ed. Ashton Spacey), page 119:

      Betas are usually second in command to the reigning alpha, and omegas belong to the lowest caste of the social hierarchy.
