Batgender

Batgender is a xenogender that focuses on bats and/or vampires. One's gender may be impacted by bats, best described as bat-like, or otherwise related to bats/vampires in some way. It is a faunagender and may also be a kingender.

History
It is unknown who first coined batgender and its main flag, but both have been around since at least October of 2020.

Flag
The alternative batgender flag was designed by an anonymous wiki user during October, 2020. It was designed to be less intense, less scary, and easier on the eyes. There is a version with a bat, as well as a version without a bat.

The second alternate batgender flag was designed by Twitter user @Rilya_Dewilder on May 15, 2021 as a flag to describe one of their xenogender experiences.
