After taking Despero to the authorities, Wonder Woman and Superman came across the mysterious Pandora, someone Wonder Woman was familiar with. She believed Superman could use her box to trap the evil she unleashed in ancient times; but when Superman touched it, he was overwhelmed by its power. While Pandora took the box and left, the two heroes received news that a new superhuman, Shazam, was entering the borders of Kahndaq. Their confrontation with Shazam turned violent until the rest of the Justice League and the Justice League of America intervened to defuse the situation. Suddenly, Dr. Light lost control of his powers and began absorbing Superman's solar energy, unleashing an energy beam at Wonder Woman. In a fit of anger, Superman killed Dr. Light with his heat vision, an action that caused a fight between the two Leagues.
In her debut in All Star Comics #8, Diana was a member of a tribe of women called the Amazons, native to Paradise Island – a secluded island set in the middle of a vast ocean. Captain Steve Trevor's plane crashes on the island and he is found alive but unconscious by Diana and fellow Amazon, and friend, Mala. Diana has him nursed back to health and falls in love with him. A competition is held amongst all the Amazons by Diana's mother, the Queen of the Amazons Hippolyta, in order to determine who is the most worthy of all the women; Hippolyta charges the winner with the responsibility of delivering Captain Steve Trevor back to Man's World and to fight for justice. Hippolyta forbids Diana from entering the competition, but she takes part nonetheless, wearing a mask to conceal her identity. She wins the competition and reveals herself, surprising Hippolyta, who ultimately accepts, and must give in to, Diana's wish to go to Man's World. She then is awarded a special uniform made by her mother for her new role as Wonder Woman and safely returns Steve Trevor to his home country.
Diana's treacherous paternal half-brother, based on the Greek mythological god of war, who masquerades as a speaker for peace on the Imperial War Cabinet as part of his deceptive master plan of conquest and destruction. Describing the Sir Patrick persona of his character, Thewlis said, "Sir Patrick's entire drive through the other half of the story is to bring about the armistice. That's his whole intention no matter what's going on. He meets Diana and see in her somebody who is sympathetic to his cause, quite vehemently so."
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.
As Zola defeated Poseidon, the First Born returned to Olympus and ordered the Minotaur to attack Wonder Woman. The Minotaur, however, refused to kill her and the First Born killed him instead. Upon seeing the unmasked Minotaur, Diana discovered her foe was the creature she had spared in the labyrinth. Wonder Woman furiously threw the First Born into the abyss he was originally trapped in while Zola placed Zeke on the throne. Zola revealed herself to be Athena and Zeke to be another iteration of Zeus himself. Both had planned for Wonder Woman to fight the First Born and accept her destiny as a goddess. With the conflict ended, Athena planned to put an end to her human identity and become a goddess once more, but Wonder Woman convinced her to allow Zola and Zeke to live without godly interference.
Hermes attacked Wonder Woman there, refusing to simply give up the child, but during their battle, War ripped the baby from Demeter's womb and disappeared. Unable to let a grave wound such as that go unattended, Diana saw to Demeter first, and the goddess warned that War could not be trusted. Worriedly, Diana and Orion returned to Manhattan to find that War had returned the baby to Zola. At last, the baby and his mother were reunited - and Orion would not have to look any further for the child he needed to kill.
The modern age of the character can be tied to the reboot of the character following Crisis on Infinite Earths. In this the character became defined by the vision of George Perez in a way which the entire concept of the character was defined by his direction. As opposed to the past where the character would get retold origins which would try to make her more contemporary, now she got one which tied her much more strongly to the stories of the ancient gods. For the first time Diana enters Man’s World not knowing how to speak English already, and is forced to master the language on her own. In this period she also became much more closely related with modern female issues, and this was usually through her circle of friends – Julia and Vanessa Kapatelis and Mindi Mayer. Such issues as the cultural need for women to be attractive and thin, suicide and the sensationalization of the media as it pertains to women were all addressed. This version of the character also reimagined Steve Trevor as a father figure for Diana as opposed to a romantic counterpart. After Perez’s run on the character, she was taken over for a time by William Messner Loebs, who recast her again in somewhat more traditional superhero stories, though in this case she still explored a different aspect of humanity. After a long space voyage, when she returned home she was forced to work at a fast food restaurant to pay her bills and made friends with a number of people in her “civilian identity.” This built up to the revelation of betrayal of her mother, and of Artemis taking over as Wonder Woman for a short time, but this was soon reversed. The following writer was John Byrne, who when he was writing Superman in the post-Crisis on Infinite Earths DC universe, had hinted at a relationship between Diana and Superman. This was explored occasionally under his run, but it is probably best known for the death of Diana, and the assumption of her duties by Hippolyta. She was soon returned to life (as she had never really died, instead having been deified). This period also introduced Cassandra Sandsmark, who would go on to become Wonder Girl at a later point. The remainder of this second series is best remembered for by the writing of Jimenez and Rucka, both of whom helped define the character. The latter during the lead-in of events to Infinite Crisis had Diana fighting Superman who was being controlled by Maxwell Lord. Battered after their battle, Diana has managed to stop Superman by using her lasso of truth on Lord, and the only option which she is given to stopping him is to kill him, and realizing this is the case, she does so. This created a controversy both within comics and in the real world, as both fans and characters alike debated the morality of this decision. In comics this also led to strained relations between her and Superman and her and Batman and with the addition of the events of Identity Crisis, helped to lead to the breakup of the Justice League of America at a crucial point right before the main events of Infinite Crisis were about to begin.
Wonder Woman experienced significant changes from the late 1950s through the 1960s during the Silver Age of Comic Books. Harry G. Peter was replaced by Ross Andru and Mike Esposito in issue #98 (May 1958), and the character was revamped as were other characters in the Silver Age. In Diana's new origin story (issue #105), it is revealed that her powers are gifts from the gods. Receiving the blessing of each deity in her crib, Diana is destined to become as "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Mercury". Further changes included the removal of all World War II references from Wonder Woman's origin, the changing of Hippolyta's hair color to blonde, Wonder Woman's new ability to glide on air currents, and the introduction of the rule that Paradise Island would be destroyed if a man ever set foot on it.
The sister of Hippolyta, general of the Amazonian army, Diana's aunt and mentor. On being cast for the film, Wright said, "It's two-fold because when Patty Jenkins called me, the director, it was a three-minute long conversation. She said, 'I'm doing a movie about Wonder Woman. Do you want to be her trainer?' And I was like, 'Yes. Of course.' And the general of the Amazonian army. That was pretty cool." Describing her character mentoring and training Diana to be a warrior, Wright said, "It's a sixth sense that it is coming and I think that's also in the mythological story behind Antiope and Queen Hippolyta. They know it's coming and it's her duty as the aunt to her young niece to make sure she is the fiercest warrior of all time." On the Amazons fighting style, Wright said, "It's hand combat. Yes, swords and knives and arrows, but the precision that they have, right, as these warrior women; it's so nice to see that disparity between what we had in the day of just raw fighting materials and the guns and how easy that is in comparison." The message of the film, Wright stated, "is not just female empowerment. It's about love and justice. That's what the film's about. And what a great message to spread to our little ones." Commenting about training for the film, Wright said, "The most empowering was to get into that physical shape. So we were doing horseback riding training, weight training, martial arts, and 2,000 to 3,000 calories a day".
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
