At the end of the 1960s, under the guidance of Mike Sekowsky, Wonder Woman surrendered her powers in order to remain in Man's World rather than accompany her fellow Amazons to another dimension. Wonder Woman begins using the alias Diana Prince and opens a mod boutique. She acquires a Chinese mentor named I Ching, who teaches Diana martial arts and weapons skills. Using her fighting skill instead of her powers, Diana engaged in adventures that encompassed a variety of genres, from espionage to mythology. This phase of her story was directly influenced by the British spy thriller The Avengers and Diana Rigg's portrayal of Emma Peel.
In May 2017, early tracking had Wonder Woman opening with $65–75 million, and possibly as high as $105 million. The film opened Friday, June 2, 2017, across 4,165 theaters and made $38.7 million on its opening day, including $3.7 million in IMAX. It was the biggest single-day gross for a woman-directed film, ahead of the $35.9 million opening Friday of Catherine Hardwicke's Twilight in 2008 and the biggest opening day for a woman-led comic book superhero film, ahead of Ghost in the Shell ($7 million). This included $11 million it made from Thursday previews, also the best start for a film directed by a woman, surpassing Fifty Shades of Grey's $8.6 million which was directed by Sam Taylor-Johnson, and the third-biggest of the year, behind Beauty and the Beast and Guardians of the Galaxy Vol. 2. Of that, $1.5 million came from IMAX screenings.
Following the Rebirth retcon, the "Year One" storyline explains that while put in a cell after coming to Man's World, Diana was visited by the Greek gods in animal form. Each gave her powers that would reveal themselves when she needed them to. She first displays strength when she accidentally rips the bars off her cell door when visited by Steve Trevor, Etta Candy, and Barbara Ann Minerva. Later on a trip to the mall, she discovers super speed, great durability, and the power of flight while fighting off a terrorist attack.
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."
With Wonder Woman arriving in pursuit, Strife warned of the prophecy Apollo and Artemis feared: a child of Zeus would kill a god to take the throne. That child could be either Diana or Zola's child. Sending Zola back with Hermes to have her baby in peace, Diana warned that if they were not left alone, she would fulfil the prophecy herself. Unfortunately, upon her return to Michigan, Diana found that Hermes had betrayed them, and once Zola gave birth to her son, he whisked the child away, and gave it to Demeter. Diana swore to get the boy back and bring Hermes to justice.
Steve Trevor died at the end of Wonder Woman after sacrificing himself to ensure that a plane full of deadly gas couldn’t harm anyone on the ground. Is this Steve Trevor the same Steve Trevor that we saw in Wonder Woman who was transported to 1984 because of something like time travel, a descendant of Steve Trevor’s who is also named Steve Trevor (and looks exactly like Pine), a clone, or something else entirely? (It’s a comic book movie, so anything is possible.)
In London, they deliver Maru's notebook to the Supreme War Council, where Sir Patrick Morgan is trying to negotiate an armistice with Germany. Diana translates Maru's notes and reveals that the Germans plan to release the deadly gas at the Western Front. Although forbidden by his commander to act, Steve, with secret funding from Morgan, recruits spy Sameer, marksman Charlie, and smuggler Chief Napi to help prevent the gas from being released. The team reaches the front in Belgium. Diana goes alone through No Man's Land and captures the enemy trench, allowing the Allied forces to help her liberate the village of Veld. The team briefly celebrates, taking a photograph in the village, while Diana and Steve begin to develop their own romance.
After the death of Superman, Wonder Woman became depressed and began to remember her origins differently, questioning aspects of her past such as whether she truly was mocked as a child and her relationship with Ares. In a fit of rage Diana crushed the helmet of War. Realizing that she shouldn't have been able to do that, she used the Lasso of Truth on herself and discovered that she had been deceived. Diana traveled to Olympus for answers, but found it abandoned. She also found herself unable to return to her home of Themyscira.
The Lasso of Truth, or Lasso of Hestia, was forged by Hephaestus from the golden girdle of Gaea. The original form of the Lasso in the Golden Age was called the Magic Lasso of Aphrodite. It compels all beings who come into contact with it to tell the absolute truth and is virtually indestructible; in Identity Crisis, Green Arrow mistakenly describes it as "the only lie detector designed by Zeus." The only times it has been broken were when Wonder Woman herself refused to accept the truth revealed by the lasso, such as when she confronted Rama Khan of Jarhanpur, and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity. During the Golden Age, the original form of the Lasso had the power to force anyone caught to obey any command given them, even overriding the mind control of others; this was effective enough to defeat strong-willed beings like Captain Marvel. Diana wields the Lasso with great precision and accuracy and can use it as a whip or noose.
