Omegaverse works are most frequently focused on male-male couples composed of an Alpha and an Omega,[6] though heterosexual Omegaverse works have been produced,[13] and by 2013, about 10% on Archive of Our Own were labeled male/female.[8] Some subvert the genre tropes, telling stories about illicit relationships between Alphas, Omegas who hide their smell using chemical pheromones so that they are not a victim of biological prejudices,[22] or dominant Omegas and submissive Alphas.[2] Non-traditional couples are often featured in Japanese Omegaverse works.[23]Since Omegaverse is a type of folksonomy, some of its aspects are included or excluded at the discretion of the story author.[8] Sometimes Betas are absent, or other intermediate designations such as Deltas and Gammas are added.[17] The genre often features other fantasy elements, such as the presence of werewolves or other fantastical creatures.[1] Some works introduce a rigid caste system, where Alphas are depicted as the upper class elites while Omegas are at the bottom tier and face discrimination and oppression because of their physiology, creating an example of biological determinism.[7][18][19] In darker stories, this results in non-consensual or dubiously consensual intercourses, forced pregnancies, Omegas kidnapping and sexual slavery.[20][21]Omegaverse fiction typically focuses on wolf or other canid-like behavior in humans, especially as it pertains to sexual intercourse and sexuality, which is described as instinctual, responding to animalistic physiological stimuli.[1][2] This includes rutting and heat cycles, pheromonal attraction between Alphas and Omegas,[12] penises with knots (used to "knot", or tie, the partner to an Alpha during copulation, an action known as "knotting"),[1] scent marking,[13] imprinting,[8] breeding, mating rites, pack structures[14] and potentially permanent psychic bonds with a mate.[6] Between Alphas and Betas, only females can carry on a pregnancy, but male Omegas are often envisaged as being able to become pregnant via a uterus connected to the rectum,[14][15][16] and Alphas can impregnate regardless of their main gender.[17] To make penetration and impregnation easier, male Omegas often have self-lubricating anuses.[9]
