It should be stated, that the USE of terms such as Futanari, Shemale, Transgender and Herm are dry scientific terms ONLY. They do not represent any specific view by the Earth-971 Administration. They are descriptors of 'races' in a game, much as Goblin, Kobold, Elf, Dwarf and Drow are descriptors in Dungeons & Dragons. Any and all documentations regarding gender in Earth-971, is specific to the Earth-971 setting and are written from the objective perspective of a Dungeonmaster describing a game world.
Futanari are considered a third biological gender, with their own assigned chromosomes that determine male-like (Z chromosome) and female-like (W chromosome qualities/traits. Futanari in regards to Earth-971 exist as a catch-all term for the following genders represented on F-List/F-Chat: Herm, Shemale, Male Herm and C-Boy. The first two represent the more 'feminine' versions of the Futanari and the last two represent more male-versions.
