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.
The "Diana Prince" identity has been part of Wonder Woman's history since her comics debut in 1941. In the early Golden Age stories, Wonder Woman served as a military secretary during World War II, using Prince as her cover. Later occupations Wonder Woman performed as Prince included translator at the United Nations, Air Force captain and ambassador, and in the '70s TV series, Lynda Carter's Wonder Woman used Prince to serve as an agent of the Inter-Agency Defense Command. In the DC Extended Universe, Prince works as curator for the Department of Antiquities at the extremely prestigious Louvre Museum and is held in very high esteem by the curator of the Gotham City Museum of Antiquities. Her tremendously long life span, accumulation of immense amount of knowledge and exceptional perceptiveness makes Diana Prince the wisest and most emotionally-intelligent member of the Justice League.
Master Combatant: Wonder Woman, having been trained in combat tactics by Menalippe and Antiope, is a tremendously skilled, fierce, and formidable hand-to-hand combatant (being at least on par with Batman), a master of a vast array of unique Amazonian martial arts, as well as an expert in most types of melee weapons (though she most frequently uses her bracelets, lasso, sword, and even shield). She has centuries of combat experience, with her claiming to have fought and defeated several beings from "other worlds" (which includes even the fearsome God of War Ares himself). Wonder Woman swiftly became the greatest warrior of Themyscira, her tremendous combat skills eventually becoming enough to rival even those of her mentor Antiope and ultimately surpassing her upon acquiring full potential, due to the latter (upon Hippolyta's insistence) training her much harder than any Amazon ever before her. Hence, Wonder Woman defeated the notorious Slipknot with effortless ease, as well as many World War I soldiers (she defeated and killed even the enhanced General Ludendorff relatively quickly), and numerous Parademons single-handedly, seamlessly incorporating hand-to-hand combat, sword-fighting with the God Killer (and later with the Sword of Athena), and the Lasso of Hestia in her own personalized, formidable style. Indeed, Wonder Woman's tremendous skill and exceptionally versatile style make her capable of effectively holding her own against either more experienced or more powerful opponents, even the mighty God of War Ares (albeit only with considerable effort and initial failure, given his superior combat experience, and her need to use a non-violent mindset), the New God Steppenwolf, an enraged resurrected Superman, and the gigantic Doomsday, with her managing to temporarily knock the latter fearsome monster down (by smashing his feet from under him with her shield), and even temporarily restrain him with her Lasso of Hestia, as well as cut off his right arm with the Sword of Athena. Indeed, had Doomsday not had his incredibly adaptable healing factor, it is safe to assume that Wonder Woman's tremendous combat skills would have allowed her to ultimately defeat him. Moreover, even when Wonder Woman's sword was destroyed by Ares, she still held her own against the more powerful Old God. However, although she put up a considerable fight, Wonder Woman was ultimately fairly quickly defeated by the resurrected Superman, and was only saved by Lois Lane's timely intervention.
The next day, they decided to infiltrate Ludendorff's gala to learn more about the weapon he and Doctor Poison are creating and how to stop it. To enter the gala, Diana stole a dress from a guest where she dances with. She is prepared to kill Ludendorff, but her attempt is intervened by Steve. She hears Ludendorff release some of the gas where it kills citizens from that town.
The Golden Age Wonder Woman had strength that was comparable to the Golden Age Superman. Wonder Woman was capable of bench pressing 15,000 pounds even before she had received her bracelets, and later hoisted a 50,000 pound boulder above her head to inspire Amazons facing the test. Even when her super strength was temporarily nullified, she still had enough mortal strength of an Amazon to break down a prison door to save Steve Trevor. In one of her earliest appearances, she is shown running easily at 60 mph (97 km/h), and later jumps from a building[clarification needed] and lands on the balls of her feet.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
