So here's the scenario: The villain of the story is male, as far as gender identity goes, but doesn't have a physical body of his own. Instead he is possessing the body of a female character for pretty much his entire part of the story, directly using her body as if it was his own. So, the character basically has a male persona but is physically female. With this in mind, should I refer to this character and male or female? Should it be: "He threw his head back and laughed" or "She threw her head back and laughed"? I actually have two separate projects where a villain does exactly this, so I'd really like to know what you guys think would work best.
