Writer Gerry Conway brought Steve Trevor back to life again in issue #271 (September 1980). Following Diana's renunciation of her role as Wonder Woman, a version of Steve Trevor from an undisclosed portion of the Multiverse accidentally made the transition to Earth-One. With Diana's memory erased by the Mists of Nepenthe, the new Steve again crash-landed and arrived at Paradise Island. After reclaiming the title of Wonder Woman, Diana returned to Military Intelligence, working with Trevor and re-joined by supporting characters Etta Candy and General Darnell.
Upon arriving, Diana and Hermes found themselves under attack by Hades' minions. Though they fought them off, they were surprised to find that time for Zola had passed much more quickly than for them. Her pregnancy was nearly at the end of its term. When they attempted to leave with her, Hades appeared, warning that one of them must stay behind - and if Diana was unprepared to make Hera his wife as promised - she would do. However, upon Eros' pistols, he instead agreed to let them all go in exchange for them. When Diana's back was turned, he fired them at her, and she fell under love's spell to him.
Morgan appears and reveals himself as Ares. He tells Diana that although he has subtly given humans ideas and inspirations, using Ludendorff and Maru as pawns in the process, it is ultimately their decision to resort to violence as they are inherently corrupt. When Diana attempts to kill Ares with the "Godkiller" sword, he destroys it, then reveals to Diana that she herself is the "Godkiller", as the daughter of Zeus and Hippolyta. He fails to persuade Diana to help him destroy mankind in order to restore paradise on Earth. While the two battle, Steve's team destroys Maru's laboratory. Steve hijacks and pilots the bomber carrying the poison to a safe altitude and detonates it, sacrificing himself. Ares attempts to direct Diana's rage and grief at Steve's death by convincing her to kill Maru, but the memories of her experiences with Steve cause her to realize that humans have good within them. She spares Maru and redirects Ares's lightning into him, killing him for good. Later, the team celebrates the end of the war. In the present day, Diana sends an email to Bruce Wayne thanking him for the photographic plate of her and Steve and continues to fight and give on the world's behalf, understanding that only love can truly save the world.
Wonder Woman (vol. 1) #179 (Nov. 1969) showed Wonder Woman giving up her powers and returning her costume and title to her mother, in order to continue staying in Man's World. The reason behind this was that all the Amazons were shifting to another dimension, but Diana was unable to accompany them as she needed to stay behind to help Steve, who had been wrongly convicted. Thus, she no longer held the title of Wonder Woman and after meeting and training under a blind martial arts mentor I-Ching, Diana resumed crime fighting as the powerless Diana Prince. She ran a mod-boutique as a business and dressed in a series of jumpsuits while fighting crime. During this period, Samuel R. Delany took over scripting duties with issue #202. Delany was initially supposed to write a six-issue story arc, which would culminate in a battle over an abortion clinic, but Delany was removed reportedly due to criticism from Gloria Steinem, who, not knowing the content of the issues Delany was writing, was upset that Wonder Woman had lost her powers and was no longer wearing her traditional costume.
Wonder Woman’s appearance in the early golden age of comics made her the first prominent female superheroine. The psychologist William Moulton Marston created Wonder Woman somewhat as a counter reaction to the presence of prominent male superheroes (at this time Superman, Batman and Captain America), as well as a counterbalance to the "blood curdling masculinity" that was dominant at the time, with the hopes that the character could serve as an inspiration for young children (though in certain ways it was geared more towards female readers.) Marston had been partially motivated to create this character because of the accomplishments of his own wife, who was also an accomplished academic at a time when it was difficult for women to fulfill this role. As a result, the first Wonder Woman series contained many complementary articles and features which sought to highlight the inner power of women. There were articles for instance on the different career paths that women could pursue (according to the standards of the 1940s) as well as a series of stories on famous and accomplished women, called the Wonder Women of History. Marston introduced the character in All-Star Comics #8 in 1941. She became the lead character in Sensation Comics in 1941, and got her first solo book in 1942.
