OK, so how are Mystique on that billboard and Wonder Woman different? Well, myself, I’m glad you asked.
For one thing, Wonder Woman is an Amazon. She’s a caricature. You can just tell that when someone first drew that costume, they really were thinking that she needs a good old torpedo between the legs to sort her out. Hercules needs to show up and take off her girldle. She’s the wild beast that needs taming. She really seems antiquated to me. How you put her in a movie today, or why you would want to, I have no clue, although I heard someone did it recently. Also, I guess she’s still in the comics.
Being a rape victim is basically her shtick. It’s her comfort zone. When Wonder Woman gets on the business end of some domestic violence, that’s just her thing. It’s just Tuesday.
Mystique, as a character and as a human being, is so totally not in her comfort zone in that picture. She was not expecting that to happen, and she’s not cool with it. And again, she’s a badass. That kind of thing does not usually happen to her, which is why the image is so striking if you know the character even a little bit. (Whatever is going on there, “casual” violence it isn’t. I mean, there’s casual violence all over the X-men, but that picture looks like shit just got serious.) There is rape imagery, but Mystique isn’t going to get “tamed” by Apocalypse any day soon. Screw that guy. She is not marrying him. She doesn’t even have a little bit of a crush on him.
How you identify with Wonder Woman in a story, I don’t know. You’re not supposed to, I guess. She’s just a floozy. The entire character just looks all-round offensive to me. (Note: This is just my impression. Again, I’m no comic book expert, so I may talking out of my behind. But I’m risking it.)
Mystique is a person. At this point, she has earned the respect of even the geeks. She’s our friend. She’s us. For most everyday purposes, she might as well be a man, and it might not even make a difference. Completely different thing. Even if she is also blue, and Jennifer Lawrence.
