I would have thought Avery was a female, seeing as Avery wears a dress and has eyelashes (though saying that, in some shots Avery doesn't have any eyelashes) like Peacock. :)

Nothing is really confirmed though - Avery could be genderless for all we know! It was likely intended for Avery to have as many similar traits to Peacock possible.
