Is BMO From Adventure Time Expressive of Feminism?

Yes he's a video game system, but she is so much more than that!! BMO from the fantastic show Adventure Time identifies as both male and female, and because of that expresses the ideals of Third Wave Feminism!! Third Wave Feminism questions if gender is actually binary, tied to our biological sex. Is our understanding of masculinity and femininity fair, or even ACCURATE? Of course, BMO has no biological gender, so there's no cultural expectations that anchors her (him?) down. But it all seems a non-issue in the Adventure Time world.
