Omegaverse
Omegaverse, also known as A/B/O, is a subgenre of speculative erotic fiction, and originally a subgenre of erotic slash fan fiction. Stories in the genre are premised on societies wherein humans are divided into a dominance hierarchy of dominant "alphas", neutral "betas", and submissive "omegas". These terms are derived from those used in ethology to describe social hierarchies in animals.
