Following Pérez, William Messner-Loebs took over as writer and Mike Deodato became the artist for the title. Messner-Loebs introduced Diana's Daxamite friend Julia in Wonder Woman vol. 2 #68 during the six-issue space arc. Messner-Loebs's most memorable contribution to the title was the introduction of the red-headed Amazon Artemis, who took over the mantle of Wonder Woman for a short time. He also included a subplot during his run in an attempt to further humanize Diana by having her work for a fictional fast food chain called "Taco Whiz".
Zeus Action Comics #267 (August 1960) Zeus is the ruler of Olympus, King of the Gods, God of the Sky, Thunder, Law, Order, and Justice who is based on the god of the same name. Post-Crisis, he became enamored with Wonder Woman's beauty and grace. Later, Ares used his son Eros in a plot to make Zeus fall in love with the amazon Artemis, which enraged Hera into destroying Themyscira. He was later overthrown by Athena, though he attempted to reclaim his throne with the help of Hades and Poseidon. In the New 52, it was revealed that Zeus was Wonder Woman's father. Post-Rebirth, Zeus appeared as an ally for Wonder Woman in the form of a Falcon.
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.
Although she initially forbids Diana to be trained as a warrior, Hippolyta reluctantly agrees to let General Antiope, Hippolyta's sister and Diana's aunt, train her, only more rigorously than any other warrior. In 1918, Diana, now a young woman, rescues US pilot Captain Steve Trevor when his plane crashes off the Themysciran coast. The island is soon invaded by German soldiers that had been pursuing Trevor. The Amazons kill the crew, but Antiope sacrifices herself to save Diana. Steve is interrogated with the Lasso of Hestia and reveals that a great war is consuming the outside world and that he is an Allied spy. He has stolen a notebook of the chief chemist Dr. Isabel Maru, who is attempting to engineer a deadlier form of mustard gas under the orders of General Erich Ludendorff from a weapon facility in the Ottoman Empire. Believing Ares to be responsible for the war, Diana arms herself with the "Godkiller" sword, the lasso, and armor before leaving Themyscira with Steve to locate and stop Ares for good.
Wonder Woman also met the Lamia of myth, who laid with Zeus and bore his children. Hera changed her into a snake-like creature and killed her children. She now lurks in the American sewers, acting as a benevolent caregiver to troubled children. She attempted to commit suicide using Diana's lasso (which she had her young friend Sneaker steal), but Diana stopped her and Lamia disappeared along with Sneaker, with whom she had developed a mother-daughter relationship.
