Zeronian is a gender that is essentially best described through the properties of zero. It has no opposite (antigender), but it has no eugender form either. It is unrelated to any and all other genders and cannot be defined by its relation to them. It feels like nothingness but is not a lack of gender. It is instead the embodiment of nothingness, while not necessarily being nothing itself. It is distinctly gendered, but in a unique way.
The term was coined by FANDOM user FoxesForever on April 25, 2021.
