The species sheet of imps says they are intersex but according to eevee, the accurate term for them would be hermaphrodite since it's species wide and apparently they have both types of fully functional sexual organs. Are they that and the species sheet is wrong or is it a meta kind of thing where imps would prefer to be referred to as intersex due to some sort of stigma attached to the term hermaphrodite in that universe?

Imps are outside of “male and female” sexual organs, even if their genitalia often looks like a mix. Imps are able to reproduce with species that don’t have standard genitalia or standard “male/female” sexes. They have one set of reproductive organs that changes (sometimes rapidly, sometimes slowly) according to what’s needed, and that’s not always to “egg/sperm” - hermaphroditic almost fits, but it starts to fall outside of that a little with the organs being able to change to reproduce with things that can normally only reproduce with themselves.

Intersex was picked as a term because they’re almost always going to display characteristics that don’t fit solely “male” or “female” of the species they’re a mix of. For instance, pygmy pyzkyes and regular pyzkyes are female and male respectively (as far as reproductive organs go), normally, but if you had an imp mix — there would be confusion on its appearance because it would be a mix of both. I’d pull up an example of some other male/female differences mixed into one, but we don’t have a whole lot of species with different secondary sexual characteristics yet! But imagine if we did, the imps would usually display a mix of those traits normally associated with “male” and “female”.

So basically, I picked “intersex” because they often look like they’re between male and female secondary sexual characteristics. I didn’t list “hermaphrodite” because I didn’t want to capture the idea of “male and female” organs since theirs are something different, allowing offspring with any individual who’s not sterile. This only matters more to mention as species with different methods of reproducing are introduced. For instance, Heartbreakers and Moonmen don’t have a normal set of “male/female” organs, but imps can reproduce with them regardless. In practice, it can look like hermaphroditism, but it should be differentiated. There’s no actual word for this in English that I know of, which makes this hard.

Also: I apologize, on the sheet it looks like BECAUSE they’re intersex they can reproduce with almost anything, when it should be that they’re intersex and CAN ALSO reproduce with almost anything. I didn’t mean to imply that being intersex caused the the reproductive ability, and should have taken a little more space to clarify that. (Hopefully words here will suffice in that regard.)
