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.
After Crisis on Infinite Earths, George Pérez rebooted the character in 1987. She wore an outfit similar to her 1970s one, but now with a larger glowing golden belt. This outfit continued until William Messner-Loebs' run, which had Diana pass on the role of Wonder Woman to Artemis. No longer Wonder Woman, Diana sported a new black biker-girl outfit designed by artist Mike Deodato Jr. After John Byrne took over writing and art duties, he redesigned the Wonder Woman outfit (Diana was reinstated as Wonder Woman at the end of Loebs' run) and joined the emblem and belt together.
In the Golden Age, Wonder Woman adhered to an Amazon code of helping any in need, even misogynistic people, and never accepting a reward for saving someone; while conversely, the modern version of the character has been shown to perform lethal and fatal actions when left with no other alternative, exemplified in the killing of Maxwell Lord in order to save Superman's life.
Gaines was troubled. Roubicek, who worked on Superman, too, had invented kryptonite. She believed superheroes ought to have vulnerabilities. She told Gaines she thought Wonder Woman ought to be more like Superman and, just as Superman couldn’t go back to the planet Krypton, Wonder Woman ought not to be able to go back to Paradise Island, where the kinkiest stuff tended to happen. Gaines then sent Roubicek to Bellevue Hospital to interview Bender. In a memo to Gaines, Roubicek reported that Bender “does not believe that Wonder Woman tends to masochism or sadism.” She also liked the way Marston was playing with feminism, Roubicek reported: “She believes that Dr. Marston is handling very cleverly this whole ‘experiment’ as she calls it. She feels that perhaps he is bringing to the public the real issue at stake in the world (and one which she feels may possibly be a direct cause of the present conflict) and that is that the difference between the sexes is not a sex problem, nor a struggle for superiority, but rather a problem of the relation of one sex to the other.” Roubicek summed up: “Dr. Bender believes that this strip should be left alone.”
The "Year One" storyline retells Diana's origin growing up on Themyscira. She lives an idyllic life and harbors interest for the outside world, and the first connection to it comes in the form of Steve Trevor, who crashes on the island and is the sole survivor. A contest is held to determine which Amazon is the best candidate to take Steve home, with Diana volunteering despite knowing the cost to leave the island is to never return. Diana wins the contest and departs with Steve. Once arriving in America, Diana is taken into custody by the government to discern her origins. She meets Etta Candy and Barbara Ann Minerva along the way. While incarcerated Diana is visited by the gods in animal form and bestow upon her powers of strength, speed, agility, durability, and flight. She discovers Ares, the god of war, is working to destroy humanity. Accepting her new role in Man's World, Diana, with the help of the gods in animal form, subdues Ares with the lasso. Now called Wonder Woman, Diana becomes one of the world's greatest heroes.
The Invisible Plane appeared in the very first comic stories, including All-Star Comics #8, where it is shown as being able to fly at over 2,000 mph (3,200 km/h) and to send out rainbow rays that penetrate the mist around Paradise Island, as well as landing stealthily and having a built-in radio. Wonder Woman is seen storing the plane at an abandoned farm near Washington, D.C., in the barn; she goes there as Lt. Prince and changes clothes in some of the earliest tales. Though never explicitly stated, the Plane is presumably stored there when not in use for the rest of the Pre-Crisis era. In a story published shortly after, it flies at 40 miles (64 km) a second.
Wonder Woman's outfit has varied over time, although almost all of her outfit incarnations have retained some form of chestplate, subligaculum, tiara, bracelets, and her signature five-pointed star symbols. When Wonder Woman was first introduced, she wore a heavily patriotic skirt and red top which incorporated an American eagle and elements of the United States flag, reflecting the comic's origins during World War II. Later artists introduced what would become Wonder Woman's classic ensemble, adding an armored plate to her top whose design recalls a letter W and revealing blue short shorts, whose precise length varied from artist to artist. Other artists have experimented with different looks for Wonder Woman over the years, including an all-white mod jumpsuit, a biker outfit, a variation of her mainstream depiction featuring leather pants and a jacket, and a number of armoured battlesuits. Contemporary artists have attempted to emphasise Wonder Woman's traditional outfit as a red armored top with a blue gladiator skirt.
The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
Invisible Plane: Wonder Woman possesses an airplane capable of rendering itself completely invisible to the human eye. Like her bracelets, Diana's invisible plane is forged with Eighth Metal, making it almost indestructible. The Invisible Plane was originally the aircraft Steve Trevor crashed onto Themyscira; it was repaired by the Amazons and upgraded with their technology.
Upon arriving, Diana and Hermes found themselves under attack by Hades' minions. Though they fought them off, they were surprised to find that time for Zola had passed much more quickly than for them. Her pregnancy was nearly at the end of its term. When they attempted to leave with her, Hades appeared, warning that one of them must stay behind - and if Diana was unprepared to make Hera his wife as promised - she would do. However, upon Eros' pistols, he instead agreed to let them all go in exchange for them. When Diana's back was turned, he fired them at her, and she fell under love's spell to him.
Trudging on, Hades expects their presence and tries sending spirits in order to stall and attack Diana and Hermes. Successfully defeating them, they wonder through a forest and find a cabin resembling Zola's farm house. Zola pops out and happily hugs Wonder Woman. Hades at that moment makes his grand entrance and frees them. Though, just before they escape, Hades beckons Wonder Woman to look behind, and shoots her with Eros pistols. She urges Hermes and Zola to leave while she is left at the mercy of Hades who wants her to be his bride. Here, she is preparing to wed Hades when she gives Diana her lasso, saying that if he truly loves him, she will confess it due to the properties of the lasso. She says yes, but will not go on with the wedding as it is more or less forced and not real love. She escapes his clutches and shoots him as a means of payback for shooting her.
