An American pilot and the love interest of Diana. On his role for the film, Pine said, "I am an American pilot who's a spy. It's like a boy's dream: You're either a spy or a fighter pilot. The first thing I wanted to be was a fighter pilot a long time ago. I wanted to be Goose [from Top Gun]". As to how his mortal character would interact with an Amazon, Pine stated, "When I first read the script, it had elements of Romancing the Stone, kind of a very classic fish out of water. Two people that don't really bond well at first and they're butting heads and just fun, witty banter". When speaking about meeting the director and being cast, Pine said, "Patty is a pretty incredible human being. When we first met about the part of Steve, she sat across from me and essentially acted out the entire film over the course of a two-hour lunch. She was so specific, so articulate, and so ardent. I would've said yes just for Patty alone." Pine went through a workout regimen for the film, commenting, "I got in incredible shape for this film" but also joking "I was also wearing about 75 pounds of clothing. What I realized is that I made a major mistake, I got in great shape and they just put clothes over all my hard work."
The team learns that a gala will be held at the nearby German High Command. Steve and Diana separately infiltrate the party, with Steve intending to locate the gas and destroy it, and Diana hoping to kill Ludendorff, believing that he is Ares and thus killing him will end the war. Steve stops her to avoid jeopardizing his mission, but this allows Ludendorff to unleash the gas on Veld, killing its inhabitants. Blaming Steve for intervening, Diana pursues Ludendorff to a base where the gas is being loaded into a bomber aircraft bound for London. Diana fights and kills him, but is confused and disillusioned when his death does not stop the war.
In the 1910s, Peter was a staff artist at the magazine Judge, where he contributed to its suffrage page called “The Modern Woman,” which ran from 1912 to 1917. More regularly, the art on that page was drawn by another staff artist, a woman named Lou Rogers. Rogers’ suffrage and feminist cartoons very often featured an allegorical woman chained or roped, breaking her bonds. Sanger hired Rogers as art director for the Birth Control Review, a magazine she started in 1917. In 1920, in a book called Woman and the New Race, Sanger argued that woman “had chained herself to her place in society and the family through the maternal functions of her nature, and only chains thus strong could have bound her to her lot as a brood animal.” In 1923, an illustration commissioned by Rogers for the cover of Birth Control Review pictured a weakened and desperate woman, fallen to her knees and chained at the ankle to a ball that reads, “UNWANTED BABIES.” A chained woman inspired the title of Sanger’s 1928 book, Motherhood in Bondage, a compilation of some of the thousands of letters she had received from women begging her for information about birth control; she described the letters as “the confessions of enslaved mothers.”
