In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
She later became a major character in the DC Animated Universe in Justice League and its sequel, Justice League Unlimited. Both shows were massively popular and helped bring Wonder Woman back to relevance for a younger generation. The DCAU is notable for introducing the idea of a romance between Batman and Wonder Woman, something that was unheard of in the original comic books. Throughout the DCAU, Wonder Woman was voiced by Susan Eisenberg.
Writer Gerry Conway brought Steve Trevor back to life again in issue #271 (September 1980). Following Diana's renunciation of her role as Wonder Woman, a version of Steve Trevor from an undisclosed portion of the Multiverse accidentally made the transition to Earth-One. With Diana's memory erased by the Mists of Nepenthe, the new Steve again crash-landed and arrived at Paradise Island. After reclaiming the title of Wonder Woman, Diana returned to Military Intelligence, working with Trevor and re-joined by supporting characters Etta Candy and General Darnell.
Wonder Woman continued to use the plane for super speed, outer space, and multi-dimensional transport up until the unpowered era of Diana Prince. When Wonder Woman resumed superpowered, costumed operations in 1973, she continued to use the jet as before, but did glide on air currents for short distances. At one point, Aphrodite granted the plane the power to fly faster than the speed of light for any interstellar voyages her champion might undertake. Thanks to tinkering by gremlins, the Plane even developed intelligence and the power to talk. The plane proved a good friend, eager to help his "mistress" and her loved ones in any way possible. It got along especially well with Steve Trevor.
Feminist icon Gloria Steinem, founder of Ms. magazine, was responsible for the return of Wonder Woman's original abilities. Offended that the most famous female superhero had been depowered into a boyfriend-obsessed damsel in distress, Steinem placed Wonder Woman (in costume) on the cover of the first issue of Ms. (1972) – Warner Communications, DC Comics' owner, was an investor – which also contained an appreciative essay about the character. Wonder Woman's powers and traditional costume were restored in issue #204 (January–February 1973).
Diana, after her death, was granted divinity as the Goddess of Truth by her gods for such faithful devotion. During her brief time as a god of Olympus, Diana was replaced in the role of Wonder Woman by her mother, Queen Hippolyta. Unlike Diana receiving the title of Wonder Woman in honor, Hippolyta's role as Wonder Woman was meant to be a punishment for her betrayal in Artemis' death as well as for unintentionally killing her own daughter. However, Hippolyta eventually grew to enjoy the freedom and adventure the title came with. Whereas Diana used the Lasso of Truth as her primary weapon, Hippolyta favored a broad sword.
When Marston died in 1947 Robert Kanigher took over and Diana became less of a feminist character but during this time, her abilities expanded as she wore earrings that provided her with the air she needed when she was in outer space and she had an invisible plane. Extra additions included a tiara which could cut through almost anything and acted as a boomerang and her bracelets now had two way radios.
