Hell, as long as we're at it, how about siccing Asia the Invincible from the Swordsman wuxia movies on them? Asia would straightaway set about trying to take the place over, and silly little gender categories be damned!

(I'm still not altogether sure what pronouns to assign the character--we're talking about someone who starts out with a penis and testicles, develops an increasingly feminized appearance after being castrated as a prerequisite to mastering an esoteric kung-fu style, and thereafter presents as whatever gender seems most convenient.)
