The events of Crisis on Infinite Earths greatly changed and altered the history of the DC Universe. Wonder Woman's history and origin were considerably revamped by the event. Wonder Woman was now an emissary and ambassador from Themyscira (the new name for Paradise Island) to Patriarch's World, charged with the mission of bringing peace to the outside world. Various deities and concepts from Greek mythology were blended and incorporated into Wonder Woman's stories and origin. Diana was formed out of clay of the shores of Themyscira by Hippolyta, who wished for a child; the clay figure was then brought to life by the Greek deities. The Gods then blessed and granted her unique powers and abilities – beauty from Aphrodite, strength from Demeter, wisdom from Athena, speed and flight from Hermes, Eyes of the Hunter and unity with beasts from Artemis and sisterhood with fire and the ability to discern the truth from Hestia. Due to the reboot, Diana's operating methods were made distinctive from Superman and Batman's with her willingness to use deadly force when she judges it necessary. In addition, her previous history and her marriage to Steve Trevor were erased. Trevor was introduced as a man much older than Diana who would later on marry Etta Candy. Instead, Perez created Julia and Vanessa Kapatelis, a Greek-American scholar and her teenage daughter whom Diana would live with when she was in Man's world and would be major supporting characters in the series for years.
In 2016, "Issue #48" of Sensation Comics, featured Wonder Woman officiating a same-sex wedding, drawn by Australian illustrator Jason Badower. "My country is all women. To us, it's not 'gay' marriage. It's just marriage", she states to Superman. Inspired by the 2015 June Supreme Court ruling that established marriage equality in all 50 United States, Badower says DC Comics was "fantastic" about his idea for the issue. In an interview with The Sydney Morning Herald, he said his editor "Was like 'great, I love it! Let's do it.' It was almost anticlimactic." "Diana's mother, the queen, at the very least authorized or in some cases officiated these weddings," Badower says. "It just seems more like a royal duty Diana would take on, that she would do for people that would appreciate it."
Later, Diana, Zola and Hera had lunch while they were watched by Hermes. Orion, believing Hermes had bad intentions, attacked him before being stopped by Wonder Woman, and at the same time Strife appeared. Back at the apartment, Strife gave War's helmet to Diana, even though Diana still felt uncomfortable at becoming the new Goddess of War. In that moment, Siracca entered the apartment and told Diana that Milan had been captured by Cassandra. Wonder Woman asked Hermes to take her to Chernobyl, and he accepted to help.
Cheetah isn't the only one experiencing unexplained bouts of rage; this type of behavior is happening globally. Across the globe, thousands of people are lashing out in anger, rioting and swearing off the gods they once worshiped, all of them praising that these next gods, the Dark Gods, will be coming soon. According to Trevor, those that are affected by this rage are people whose confidence and belief in their respective gods is shaken, no matter who they are, and no matter what planet they come from.
The British War Council quickly gathered to discuss the notebook. Their codebreakers were unable to decipher the two different languages that it was written in, but Diana quickly identified them as Ottoman and Sumerian. She read the book out loud, informing the council that Doctor Poison had created a new form of mustard gas based on hydrogen instead of sulfur, which gas masks would be useless against.
Wonder Woman was legally barred from appearing in the first few seasons of the Batman: The Brave and the Bold, but made a cameo from behind in the episode "Sidekicks Assemble!" She later made a full appearance in the final season during the episode "Scorn of the Star Sapphire!," and played a main role in the episode "Triumvirate of Terror!" In the show, she was voiced by Vicki Lewis.
