Genderlight
Not to be confused with Lightgender.
Genderlight or Panzerogender is a xenogender identity in which all the genders accessible to one in their life and culture combine with their antigender/opposite gender(s), and in turn become nullified/mixed.
An example would be one having a feminine gender and a masculine gender that 'fight' and end up destroying each other, leaving them as a neutral gender or genderless.
It is different from zerogender in the sense that it does not sprout a new gender/restart when combined, just ends up destroying itself.
