The origin of Wonder Woman and the psychological reasoning behind why William Morton Marston created her in the way he did illustrated Marston's educational, ethical, and moral values. "William Marston intended her to be a feminist character, showing young boys the illimitable possibilities of a woman who could be considered just as strong as the famed Superman." Gladys L. Knight explains the impact and influences that superheroes have on us in society ranging from the 1870s until the present day.
Carolyn Cocca has stated that Wonder Woman possesses a "duality of character" due to the character possessing both feminine and masculine qualities in her physical abilities and attitude, which Cocca felt made her more appealing to a wide audience. Wonder Woman's first female editor, Karen Berger, claimed that, "Wonder Woman [is] a great role model to young women, but also contains many elements that appeal to males as well. Wonder Woman crosses the gender line.". Berger worked with George Pérez on the new issues of Wonder Woman starting in 1987, and the new Diana "works with friends and allies to teach lessons of peace and equality."
As Themyscira's emissary to Man's World, Diana has made it her duty to lead by example, even if the differences between her birthplace and new home sometimes present hurdles for her to jump. She has come to represent the possibility and potential of life without war, hate or violence, and she is a beacon of hope to all who find themselves in need. She stands as an equal among the most powerful Super Heroes, with a sense of purpose to protect the world from injustice in all forms.
In some ways, those early Wonder Woman comics are hokey, outdated and a wee bit sexist. But they're a lot of fun to read. Unlike so many creators working in the nascent early days of the superhero genre, Marston didn't simply recycle the same tropes, but worked to create a new kind of hero who could speak to a more liberated and progressive culture. Both he and his creation were very much ahead of their time.
The JLA's first trip to the universe is where Owlman is found hacking computer systems to get the info he needs. There, the JLA fights recruits the Crime Syndicate of America has recruited. Their second trip was when Batman followed Superwoman, and defeats her. After taking out Superwoman, he calls the JLA, and alongside the JLA travels to the moon, to get to the Crime Syndicate's headquarters. From there on, every JLA'er fights against their counterparts, and Wonder Woman manages to even win against her counterpart, Superwoman.
