This one is entirely the costume. It would actually look better if Wolverine was naked.
Here Queen Sonja is killing some monster with a pair of swords and Hawkeye is, I don't know what he's doing. But in both cases, it's the costume that's the problem.
Again, it's the costume that's the problem. Take away the bare middrift and it's perfectly reasonable.
This one looks worse because he's using a bow instead of a gun.
In this one we've got a badly drawn variation of the horse stance and deadpool isn't looking where he's shooting. Psylocks legs are drawn more stupidly, but her aim is better, because she's not shooting anything, she's using a psychic knife.
Or this one, Wonder Woman is punching someone while blocking bullets behind her. I don't know what hawkeye is doing. And, in any case, it's entirely the costume that makes it look bad, particularly in the butt area.
Or the Avengers poster, where Black Widow is shooting someone off screen with her wrist-mounted gun and is using a stance that gives her a more stable aim.
Or this one, where Black widow is using centripetal force from you leg rotation to power a 360 degree spin so that she can shoot a bunch of people with her wrist guns. Which is stpuidly complex, but looks cool.
Hawkeye, meanwhile, is using a bow, making that technique useless for him.
And then there's this jump kick to the face, which would look better if those performing it were wearing pants. Again, it's entirely the costume.
Of course, I'd be dishonest if I didn't admit that the reason many of those sexy costumes and poses look gay on Hawkeye is that they're designed to be sexually attractive to men.
But even when a female character is overtly sexual, it does not follow that she is a sex toy for men. Poision Ivy is overtly sexual, but I would not want to fuck her. That's a quick way to die. Her sexuality is a weapon that she uses against others. The same is true for Morrigan from Darkstalkers, a lifedraining succubus. Sex with her would be invariably lethal.
Rather, the reason that many female characters are drawn sexy isn't to present them as submissive fucktoys, as it were, but the opposite. Sexual power is a subset of power. Sexuality is a form of power. Characters who flaunt their sexuality generally do so because they're completely in control of it and comfortable with it, and because it gives them power over overs. If you're attracted to someone then they do have a measure of power over you.
Sometimes this is more literal than others. In One-Piece, if you're attracted to Boa Hancock then she can turn you to stone, an obvious metaphor for something, but also lethal.
The issue is not that women are treated as sex toys or objects. The issue is that sexual power is treated as a very female (though not necessarily feminine) sort of power most of the time, with a few exceptions.
Most of the scantily-clad women you see in comics and games are very powerful and in absolute control of their sexuality. They dress provocatively to flaunt their power, not to submit to others. And they're likely to be on top in any sexual relationship they might have.
There is, however, a lot of room to open a dialog about how women can flaunt their sexuality in our society but men can't without being seen as creepy or gay.
In other words, we need more Captain Jack Harkness.
