Omicron Male
Omicron males are usually cold blooded PYSHCKOPTAHS, they almost never feel empathy or caring for people other than themselves; although other men see them as being strong and stoic, they are often left in extreme loneliness due to women being too intimidated by their dominance to interact with them. They exhibit extreme rage when seeing other people with women due to years of being denied their right to sex. They're basically the alphas that are so alpha that can't just get women at all.
Most people looking in from the outside see omicron males as being 'losers' although the omicron knows otherwise.

However unlike upsilon males they have an napoleon complex and are much more likely to act on their fury, this makes them more similar to nu males, although they are still one of the most dominant males on the socio sexual hierarchy because of their ability to unleash their rage.
