Apogender

Apogender is a subset of agender in which one feels not only genderless but entirely removed from the concept of gender.

History
Apogender was coined on July 11, 2014 by queerspike, a since-deactivated Tumblr blog.

Flag
The flag was created by Tumblr user pastelmemer (now pastelroswell) on July 10, 2016. The meaning is unknown but it is possible that the green comes from the agender flag, and the black represents genderlessness.

Etymology
Apo is a Greek word that means away from, separate, or at the farthest point.
