A male who seeks power by any means necessary, as he believes that his rule over the people will be beneficial to them. Typically a loner, and is usually mistaken for a Sigma male, but they differ in that Xi males have an innate affinity for leading and have a killer instinct, knowing what is best for his subjects.
Person 1: You know, Thomas seems like a bit of a Xi male. He always leads the projects and gets the work done.
Person 2: I know right? At first, I thought he was a Sigma male, but it's been made clear to me otherwise.

Get the Xi male mug.
The Xi male is not male nor is it human, the Xi males actually come from the planet of Xi and come to this planet to copy human behavior to varying degrees of success. They will try to blend in amid the masses, but often stick out due to their lack of social awareness.

A good example of this type of male would be the bottom tier youtuber: Jreg
Jreg? yeah that "guy" is a certified Xi male moment

Xi males sit outside the hierarchy of other males, but use every other kind of males for their own gain. They are generally good with numbers, thus often end up pulling the strings in organizations and social situations. Xi males often trick other males, including Alpha and Sigma males into doing their bidding without the Alpha and Sigma males even knowing that they are doing things for the Xi male. In situations with women, they are extremely polite and deferent to women, treating them like actual people rather than objects to be used. They don't need to objectify women since they have so many males to do their bidding.
"Dude, yesterday, I got Jeff a coffee and I didn't even really want to. There's just something about him."
