The Crisis on Infinite Earths crossover of 1986 was designed and written with the purpose of streamlining most of DC's characters into one more-focused continuity and reinventing them for a new era, thus Wonder Woman and Steve Trevor were declared to come from the Earth-Two dimension, and along with all of their exploits, were erased from history, so that a new Wonder Woman character, story and timeline could take priority.
William Marston's earliest works were notorious for containing subversive "bondage and sapphic-undertones" subtext. Among Wonder Women's infamous catchphrases, "Suffering Sappho", was a direct reference to lesbianism. Fredric Wertham's Seduction of the Innocent referred to her as the "lesbian counterpart to Batman" (whom he also identified as a homosexual). After Marston's death in 1947, DC Comics downplayed her sexuality and feminist origin. Wonder Women, without Marston's creative direction, become more "traditional" superhero fair; the lesbian relationships and sexual imagery disappeared from the "Wonder Woman" comic, along with Wonder Woman's super powers. During the Comics Code Authority-decades since, Wonder Woman's subversiveness had been gradually stripped away; subsequent comic book writers and artists either didn't know know what do with her or barely hinted at Wonder Woman's erotic legacy. Similar to whitewashing, Wonder Woman's queerness and feminist identity throughout the latter half of the 20th century was never discussed and rendered "invisible" in adaptations in favor of the dominant sexism portrayal of women in comic books.
Even alongside all of her kindness, compassion, and empathy, Diana is still also a warrior at heart, and when someone she cares about is hurt, becomes far more relentless and ruthless. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred), and after having to watch her beloved Steve Trevor die, she flew into an agonizing rage, and she assaulted and brutalized several armed German soldiers with immense speed and ferocity. She even came close to murdering Dr. Poison as vengeance for Steve's death; but after recalling Steve's great love for an undying belief in her and her beliefs, restrained herself and refocused her energies on Ares, harnessing her love for Trevor to overcome her violent emotions and swiftly overpower an angered Ares. Additionally, she resolved to fight even harder after Steppenwolf revealed that he had killed several other Amazons. Outside of battle, however, Diana can also react indigently and negatively towards people who disrespect her, her relatives, or those she cares about. Two such notable instances were when she shot an angry look at Lex Luthor (after he insulted her father Zeus's memory), and when she shoved back Batman (after he had insulted her beloved Steve Trevor's memory). Diana also remains ruthless when facing enemies in battle as Wonder Woman, and she even shows signs of enjoying a good battle when they put up a good fight. This was seen when she briefly smiled and laughed when she was beaten to the ground by Doomsday, and smirked as she stopped the first bullet fired at a group of hostages in London.
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."
