If you have a world that doesn't have gender - that is, a world where culturally, there are no different social roles based on sex, no gendered fashion or language, etc. - that would make all the characters nonbinary. (If the author is non-binary and says that if the characters were to come into a world with a gender construct, they would identify as non-binary and be a little freaked out by people who don't). Even if the characters are of different sexes, and there's enough Gratuitous Fanservice to see what everyone's bodies are, no one identifies as separate genders, so would that make it a non-binary example of this?
"* This level was parodied in Polish movie Sexmisja (English title: Sexmission), where two male protagonists wake up from hibernation in a world where all males were killed by a pandemic and nuclear war. Women live underground and their community denies the existence of males. However, their leader is in fact a transvestite who somehow managed to survive the end of the male race, and the movie ends with our heroes manipulating a cloning machine to create a new male breed. Keep in mind, that this move was directed in the times of communism and was one big Getting Crap Past the Radar about living in a land under the control of a communist party."
Despite failing the trope in a literal sense — if there's two men in it, they aren't all women — it also seems to be a pretty big break from the spirit of the trope, as from the description here the two men sound like the main characters. I'll take it over to Gendercide if it's not already on that page, though.
Hide / Show RepliesYeah, I would cull that entry from here.
"For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled." - Richard FeynmanThe entry about Lovecraft complains about the lack of "strong female leads" — as I understand it, that's not this trope. Without knowing how many female characters there are in total, though, I don't know whether it's just badly phrased, or not an example.
I don't think that works with a single character (such as the Redford movie "All is Lost") should count. The reasons that a work might be male-only or female-only probably don't apply when there's only one character.
