A fakemon I've had kickin' around in my head since I was little: A genderless variant of Nidoran, I call Nidoran Null (or ⚲)!
I'd like to do their evolutions soon! Its a mixture of the male and female's looks. I chose the green color because green is not only a gender neutral option for babies in (afaik?) the West, it also keeps it tied to its poison typing!

"Occasionally, a peculiar variety of NIDORAN will be spotted among a group. They seem to be scrappy like their male counterparts, but without the territorial aggression. They are typically more open to befriending others, like their female variants."
