Shortly after, Diana decides to venture to the Underworld to look for Zola. Lennox requests to come, but Diana shoots down his attempt, saying that she is going solo, save for Hermes as the only way to go to Hades is to either die or be escorted by Hermes. While in the Underworld, Hermes tells that the place is more or less an extension of Hades' (now preferring to call himself "Hell") will.
The first of these half-mortal siblings to reveal himself to Wonder Woman was her older half-brother, Lennox Sandsmark, who could transform himself into living, marble-like stone and, before his death, was revealed to be the father of Wonder Girl (Cassie Sandsmark). His killer, the First Born, the eldest progeny of Zeus, would become Wonder Woman's first major super-villain of the New 52.
Wonder Woman made her debut in All-Star Comics at the end of 1941 and on the cover of a new comic book, Sensation Comics, at the beginning of 1942, drawn by an artist named Harry G. Peter. She wore a golden tiara, a red bustier, blue underpants and knee-high, red leather boots. She was a little slinky; she was very kinky. She’d left Paradise to fight fascism with feminism, in “America, the last citadel of democracy, and of equal rights for women!”
At the Louvre, Diana watched a news report showing a signal fire burning at the Shrine of the Amazons and knew that it had been sent by her mother to warn of the impending invasion. Traveling to Gotham, she breaks into Bruce's base of operations to find him tinkering with a new prototype troop carrier, the Flying Fox. It reminds her of someone she thinks of who would have loved to have flown it. Bruce tells her that he believes an invasion is imminent; she corrects him. It has already arrived.
After saving Zola from Hades, Wonder Woman tries to protect her further from Apollo, as it is prophesied that one of Zeus' children will be his downfall whom Apollo considers to be Zola's child. Wonder Woman receives the power of flight by one of Hermes' feathers piercing her thigh and Zola's baby is stolen by Hermes at the end and given to Demeter. The issue's last page shows a dark and mysterious man rising from the snow, taking a helmet and disappearing. This man is later revealed to be Zeus' first son, known only as First Born, who seeks to rule over Olympus and the rest of the world, and take Diana as his bride.[volume & issue needed]
After taking on the mantle God of War after killing her mentor War. Diana have shown some new abilities. She can now telepathically communicate and control all soldiers on the planet since she is their greatest leader. She hasn't shown the ability, but as her predecessor was able to bring back dead soldiers to fight alongside him, she might be able to do so as well.
Later, Diana is seen in the Gotham City Museum of Antiquities (with ancient Greco-Roman exhibits), conversing with an elderly couple, when the curator comes up, and offers to show her something of interest. She politely excuses herself and follows him to the exhibit of the fake replica of Alexander the Great's sword, which the ancient conqueror of the Middle East had used to cut the Gordian knot.
Wonder Woman, while in her guise as the human Diana Prince, is an extremely experienced genius antiquities dealer, with Diana's tremendously long immortal life and natural fluency in all human languages allowing her to accumulate an immense amount of knowledge on the subject, though (being an Amazon with Old God heritage) she seems to specialize most in ancient Greco-Roman antiques. Hence, Diana works as Curator for the Department of Antiquities at the extremely prestigious Louvre Museum in France, and she is held in very high esteem by the curator of the Gotham City Museum of Antiquities. She was swiftly able to tell that the museum's exhibit of Alexander the Great's sword was a fake, knowing exactly where the actual sword was and impressing Batman himself.
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.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
