Fan Casting Non-Human Non-Binary in Sort by Tropes

"Non-Human Non-Binary" refers to any non-human character or group of characters that are not exclusively male or female — they may be both or neither of these, or different genders at different times. They may be aliens who have a completely different (if any) concept of gender as we understand it, or they may be totally absent of biological sex or natural gender tendency, such as robots. Yet despite not being exactly human, they have enough human traits that we can relate to them in some way.
