>>3341816Book: Crowley is in reality a snake. Even in his "normal" form he doesn't blink, he has snake eyes and a snake tongue and "maybe, maybe not" some scales somewhere. But he takes a male form. Az takes a male form that's "soft" and "somewhat pudgy". I say somewhat because you can only see it manly in his hands.
Show: They take male forms but change them if the circumstances call for it. They can also take non-human forms, like animals. Anything to help with their work. Neil said that "predominantly they are male presenting but identifying themselves is unnecessary because they are occult creatures. Those are moral terms."
In the show and in the book they have always been "man shaped beings". So, male. Neil broadened the terms because he doesn't want to crush headcanons. He's a massive tumblr whore after all.
