Gaines decided he needed another expert. He turned to Lauretta Bender, an associate professor of psychiatry at New York University’s medical school and a senior psychiatrist at Bellevue Hospital, where she was director of the children’s ward, an expert on aggression. She’d long been interested in comics but her interest had grown in 1940, after her husband, Paul Schilder, was killed by a car while walking home from visiting Bender and their 8-day-old daughter in the hospital. Bender, left with three children under the age of 3, soon became painfully interested in studying how children cope with trauma. In 1940, she conducted a study with Reginald Lourie, a medical resident under her supervision, investigating the effect of comics on four children brought to Bellevue Hospital for behavioral problems. Tessie, 12, had witnessed her father, a convicted murderer, kill himself. She insisted on calling herself Shiera, after a comic-book girl who is always rescued at the last minute by the Flash. Kenneth, 11, had been raped. He was frantic unless medicated or “wearing a Superman cape.” He felt safe in it—he could fly away if he wanted to—and “he felt that the cape protected him from an assault.” Bender and Lourie concluded the comic books were “the folklore of this age,” and worked, culturally, the same way fables and fairy tales did.
During a training session observed by Hippolyta, Diana sparred against her fellow warriors, demonstrating her weapons expertise and defeating each of them swiftly. Her final opponent was Antiope herself. The two fought with all their might. Diana managed to disarm Antiope and looked toward her mother for approval. Antiope seized the opportunity to push Diana to the ground and pick up her sword, admonishing her for letting her her guard down. As Antiope slashed at her and forced her backwards, Diana instinctively brought her arms together to block the attack. She clashed her arm gauntlets together, resulting in her unleashing a powerful shock-wave that sent Antiope flying back and left all spectating Amazons there, including Diana herself, in complete shock.
Stealth Expert: Wonder Woman is exceptionally stealthy, as she was able to quickly sneak away from Chief and Charlie to General Ludendorff's gala, and later to steal the hacking device that Bruce Wayne had plugged into the LexCorp Industries servers and leave it in his car, without getting caught on either occasion. Later, Wonder Woman noticed Cyborg spying on her and Batman from a distance. Shortly thereafter, along with Batman and Cyborg, she was able to swiftly slip away when Commissioner Gordon turned away for a moment, and even Flash was left incredulous at how he didn't notice his teammates leave, despite having superhuman reflexes and standing right beside them. Wonder Woman even managed to enter the highly-secure Batcave itself on her own, impressing Batman.
Following the popularity of the Wonder Woman TV series (initially set during World War II), the comic book was also transposed to this era. The change was made possible by the multiverse concept, which maintained that the 1970s Wonder Woman and the original 1940s version existed in two separate yet parallel worlds. A few months after the TV series changed its setting to the 1970s, the comic book returned to the contemporary timeline. Soon after, when the series was written by Jack C. Harris, Steve (Howard) Trevor was killed off yet again.
Shortly after the team assembled, Wonder Woman assisted in helping a newly resurrected Superman regain his memories. With the team now fully assembled, Wonder Woman contributed to the successful offensive against Steppenwolf, forcing the alien invasion into retreat. Afterwards, she began to plan for the Justice League's future alongside Bruce Wayne.
When faced with a larger threat, Diana will wear her Amazon battle armour for added protection as well as use martial weapons such as swords. Technically speaking as well, as reimagined under the George Perez 1980s reboot, the iconic costume is in fact simply the breastplate of this armour. She will also additionally use a shield for added defense when she deems it necessary.
The "Lies" story arc runs parallel with and explores Diana's search. No longer able to get into Mount Olympus, Diana tracks down Barbara Ann Minerva, the Cheetah, to get help. Cheetah agrees to help in exchange for Diana aiding her in killing the god Urzkartaga and ending Minerva's curse. The pair battle their way through Urzkartaga's minions, the Bouda, and defeat Andres Cadulo, a worshiper of Urzkartaga that planned to sacrifice Steve Trevor to the plant god. Once reverted to her human form, Minerva agreed to help Wonder Woman find her way back to Paradise Island. During this time, Wonder Woman reconnects with Steve. Minerva eventually realizes Paradise Island is an embodiment of emotion instead of a physical place, so Wonder Woman and Steve head out to find the island. They succeed and Wonder Woman is greeted by her mother and sisters, though Steve senses something is wrong. Wonder Woman comes to realize nothing is as she remembers and, upon using the Lasso of Truth, discovers everything she thought she knew was a lie: she never really returned to Themyscira after departing with Steve years earlier. The revelation shatters Diana's mind and she is left nearly insane. Veronica Cale, a businesswoman who has been desiring to find Themyscira and the leader of Godwatch, sends a military group called Poison after her, but Diana's state has left her vulnerable and oblivious to the danger she and Steve are in. Steve wards them off long enough for them to be rescued, and reluctantly places Diana in a mental hospital so she can get help. While there she comes to grasp the reality she thought she knew was false, eventually coming out of her stupor and able to rejoin the others in tracking down Veronica Cale, who is trying to find Themyscira.
When last we left Wonder Woman #49, the battle brewing ever since DC's METAL cracked open the Multiverse seemed to be reaching its climax. With the Dark Gods playing similar roles to the Greek pantheon, but with all-powerful demands, enslaving humanity, Diana and her twin brother Jason were splitting up to oppose them around the globe. Just as they seemed to knock back their leader, King Best, the Dark Gods launch an assault on Jason.
