Some Jojo fujoshi uses western comics as "what is acceptable" in order to criticize Uzaki chan.

But it is common to tone down the sexuality in the cover art. I think it happens because the cover must be something you can put on the store and it is revealed months before the circulation.

This two is a example of being of the cover being adjusted/fixed after the presentation. (The second poison ivy was released in the end with a completely different cover art.)

But I do not remember that those two had so much backlash. Those ones have the impression that the publisher simply just changed it.(Poison Ivy was changed because the writer asked for it.)

The cover that was heavily criticized was this one. This shows what is unnaceptable for the readers (not for the publisher.) in USA.

This is restricted to Marvel and DC. Because when it comes to little publishers there are more extreme cover arts. I saw even free tits on a variant cover.

Since it spread more than I expected I will add some words. As I said mainstream american comics, western comics industry are trying to be for "everyone". They are adjusting the expression contents in order to achive it. In this everyone includes the ones who likes and the ones who hates sexy female characters.

The danger of taking wrong decision is very high if you concludes "this is american comics" withoutknowing how the industry moved in this 10 and some years. Also it would not be fair. So don't make foolish arbitrary decisions and I wish you to know about the "current state of american comics"

Since I don't follow the recent comics so I will cite the a bit old one.
The Mila Marana's Spider Woman variant cover incident could be a good example.

Also J.Scott Campbell's Invincible Ironman cover incident is easy to understand too.

The site has gone but there were a iniciative to swap the male poses and costumes with female costume and poses. This hawkeye initiative is an good example too.

I mean, It is normal to problematize the way the female heroes costumes and the way they are drawn.

Meanwhile the american comics(Marvel-DC heroes) has an era that made them consequentially as something like for boys, there has some appeal that pulls female readers so it does not means that female readers don't exist. I think this is a important point.

I don't pursued the DC enough so I dunno exactly but Marvel as a company is trying to find a way and doing "try and error" in order to penetrate into the female audience.

It does not make sense putting something unpleasant to the woman if you are trying to approach to them.

I think the problem of portrayal of female character in the american comics as a whole is this.
The reaction in a reactionary way of seeing woman as enemy happens because it looks like to them that the woman are getting into male territory and destroying the things they love.

As I said before Marvel are trying hard to get the female audience and marvel and DC is definitively not denying the womans so this reaction from part of male audience is meaningless.

Meanwhile in Japan, the publisher have the costume to separates the readers by sex and the readers have the trend of genderlessly having fun with the works that has born inside the male-female separation. (That's why the discussion goes about "public space" than the content itself.)

Changing the topic male heroes too are using costumes that deliniates the bodyline. Those are very sexual too. The only difference is it's not openly perceived.

That costumes that deliniates the body is the kind of clothes that chooses who can wear it. Or better saying If you don't have a very well "builded up" body it won't look well no matter the sex. Because of that there is a problem that characters with baggy bodies are being excluded. (Of course there are exceptions.)

Oh, I remembered, Spider Woman's costume was changed into something that does not exaggeratedly delineates the bodyline. I like this costume so much)
