Phoenixgender is a term used to describe a gender which the individual feels very strongly for the majority of the time, yet it will occasionally disappear without a trace for a period of time, before it comes back just as strong as before. In other words, a microlabel for agenderflux.
The phoenixgender flag was created by an unknown user on or before January 5, 2021. It consists of five stripes. Purple is used because it is commonly used to symbolize the Phoenix, bright teal to symbolize the resurrection of the gender, and black is for the loss of the gender.
