Masculinist theory designing a stand-alone category in the structure of male dominance. In this theory, the males are divided in several categories including mainly Alphas (dominant), Betas (second) and Omegas (dominated) depending on their ability to pick a woman or their supposed status before a woman.
The Zetas are thought as independent outsiders that do not let themselves be defined by women's relationship to them. They are characterised by that refusal along with the rejection of traditionalism and any relationship in which they may be dominated, but not in which they may dominate.

Seemingly a "third way" for many men that suffers from the alpha/omega dynamic, this theory supposes that men should be free and bold in their way of living, independently to women who would be an evil agent of a power structure they seek to get rid off. However, this is very damaging to the average male since this attitude can only single him out, feed him with the fantasy of a world in which women are a completely outside force of their life or create a toxic masculinity which only results in toxic social relations.

Normally the most violent of the group, during a fight the zeta male is the vanguard and inspires violence in others, is sometimes the antagonist of the alpha male when a peaceful resolution is looked for
