Born as both male and female, it is very difficult to know which one they are, though for the most part Gamma tends to be mostly feminine, taking on a female pronoun. The majority of their body is a light grey, with various dark grey markings on her body and face. Her flesh is mostly a light pink, with bright blue eyes as a nice contrast. Mostly light monochrome, there isn't any other colors in her fur, easily using it to hide when she needs to.
For the most part, their voice is rather plain, more on the feminine side, though for the most part it's very hard to tell if they sound more feminine or masculine.
