Centrois

Centrois is the leptrois gender at the center of the negatrois-positrois spectrum. It includes nongenders and is similar to neutrois, but neutrois is at the center of every gender.

Centrois is also similar to centrigender but is specifically in the center of negatrois and positrois.

Flags
Two centrois flags were created on October 26th, 2020, by a user going by Anderson. The purple represents an ocean of genders all around, the blue represents them filtering through, and the pink represents the final result of the centrois gender.

Another alternative centrois flag was created on December 22nd, 2020, by the LGBTA Wiki user VoidwyrmGaming by combining the negatrois and positrois flags.
