By the end of the war, Diana began to lose faith in both humanity and herself after Ares opened her eyes to humanity's potential for evil. While she still believed in the power of love and compassion to change humanity for the better, Diana was left sobered and emotionally broken over certain events from the war, such as the use of Dr. Poison's gas to massacre the entire village of Veld, and Steve Trevor's self-sacrificing death. After witnessing a "century of horrors", Diana largely stepped away from heroics until she witnessed the seemingly unstoppable Doomsday wreck havoc; ultimately joining in to battle him alongside Batman and Superman. After witnessing Superman's own sacrifice to stop the monster, however, Diana turned once again towards heroics; demonstrating not only her underlying belief in her own core values, but also in the positive effect true heroes can have on the world.
Indomitable Will: Wonder Woman has tremendous determination and strength of will. She refuses to ever give up, even when placed against seemingly insurmountable odds. Hence, despite the Germans invading Themyscira having far superior firepower, despite the extreme danger of German firepower in-between World War I trenches, despite having to fight the stronger and seemingly unstoppable Doomsday, despite having to battle the mighty Ares right after witnessing Steve Trevor's death, Wonder Woman promptly rose up, overcame her negative emotions, and kept on fighting, persisting until she eventually managed to gain the upper hand. Indeed, her indomitable spirit gave a renewed hope to the Wonder Men and inspired them past the point of purely monetary interests, with Chief resolving to no longer be neutral in the war and believing her story of the Olympians, Sameer finally admitting his passion for acting, and even the depressed Charlie struggling with PTSD finally beginning to sing again for the first time in years. When humanity's inherent potential for evil was revealed to her by Ares, Wonder Woman, while initially taken aback, ultimately rejected the prospect of alliance with Ares against them, even if that were to mean missing out on "paradise" on Earth, and instead courageously confronted him as the god killer. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred) and overcome by the weight of his words and the devastation of Steve's death, Wonder Woman recalled his great love for and undying belief in her, and was thereby able to muster enough willpower and love to overcome her violent emotions and defeat Ares. While mostly stepping away from superheroism for 100 years (emotionally crippled at her inability to save the Belgian villagers and Steve, and by seeing the ensuing "century of horrors"), Wonder Woman didn't entirely lose hope, and it was fully reignited again when she witnessed the self-sacrificing death of another selfless superhero, Superman (who combined the phenomenal godly might of Ares with the self-sacrificing morality of Steve Trevor), giving her enough faith to help Batman found the Justice League. During the League's battle against Steppenwolf's forces, Wonder Woman was able to inspire confidence into the inexperienced Flash and Cyborg, assuring them that they wouldn't need to fight the Apokoliptan invasion alone.
Now a mod boutique owner, the powerless Diana Prince acquired a Chinese mentor named I Ching. Under I Ching's guidance, Diana learned martial arts and weapons skills, and engaged in adventures that encompassed a variety of genres, from espionage to mythology. During this time she fought villains such as Catwoman, Doctor Cyber, the hippie gang Them!, and the campy witch Morgana.
The storyline "The Circle" was focused on the revelation of a failed assassination attempt on Diana when she was a baby, by four rogue Amazons. These Amazons – Myrto, Charis, Philomela and Alkyone, collectively referred to as The Circle – were Hippolyta's personal guards and were extremely loyal and devoted to her. However, when Hippolyta decided to raise a daughter, The Circle was horrified and considered the baby ill-fate, one who would ruin their entire race. Thus, after Diana was sculpted out of clay and brought to life, The Circle decided to assassinate the baby. Their attempt was foiled however, and the four Amazons were imprisoned. After years, the Circle escaped their prisons with the help of Captain Nazi, and decided to accomplish their previously failed mission and kill Diana. Diana defeated Myrto, Charis, Philomela and then approached Alkyone, who runs off and succumbs to her death by falling into the ocean. The other three Amazons return to their prisons.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
The story then focuses on Wonder Woman's quest to rescue Zola from Hades, who had abducted her and taken her to Hell at the end of the sixth issue of the series. The male children of the Amazons are introduced and Diana learns about the birth of her "brothers" – the Amazons used to infrequently invade ships coming near their island and force themselves on the sailors, before killing them. After nine months, the birth of the resulting female children was highly celebrated and they were inducted into the ranks of the Amazons while the male children were rejected. In order to save the male children from being drowned to death by the Amazons, Hephaestus traded weapons to the Amazons in exchange for them.
It was later retconned by Gail Simone that Wonder Woman's outfit design had Amazonian roots. During a flashback in Vol. 3, Hippolyta is shown issuing orders to have a garment created for Diana, taking inspiration from the skies on the night Diana was born; a red hunter's moon and a field of stars against deep blue, and the eagle breastplate being a symbol of Athena's avian representations.[volume & issue needed]
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.
