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.
When Hippolyta and the other Amazons were trapped in a demonic dimension, she started receiving visions about the death of Wonder Woman. Fearing her daughter's death, Hippolyta created a false claim that Diana was not worthy of continuing her role as Wonder Woman, and arranged for a contest to determine who would be the new Wonder Woman, thus protecting Diana from her supposed fate. The participants of the final round were Diana and Artemis, and with the help of some mystic manipulation by Hippolyta, Artemis won the contest. Thus, Diana was forced to hand over her title and costume to Artemis, who became the new Wonder Woman and Diana started fighting crime in an alternate costume. Artemis later died in battle with the White Magician – thus, Hippolyta's vision of a dying Wonder Woman did come true, albeit not of Diana as Wonder Woman. Diana once again became Wonder Woman, a request made by Artemis in her last seconds. Artemis would later return as Requiem. Prior to Artemis' death, Hippolyta would admit to her daughter about her own part in Artemis' death, which strained their relationship as Diana was unable to forgive her mother for sending another Amazon to her death knowingly for the sake of saving her own daughter.
Although created to be a positive role-model and a strong female character for girls and boys, Wonder Woman has had to deal with the misogyny that was commonplace in comic book industry for decades. For example, Wonder Woman was a founding member of the Justice Society of America. This roster included the original Flash and Green Lantern. Wonder Woman was an experienced leader and easily the most powerful of them all, yet was rendered a secretary. This would also be accompanied with her losing her powers or getting captured on most Justice League adventures. During the '50s and '60s, comic writers regularly made Wonder Woman lovesick over Steve Trevor, a Major in the United States Army. Stories frequently featured Wonder Woman hoping or imagining what it would be like to marry Steve Trevor.
In London, a small group of reactionary terrorists took over the Old Bailey courthouse, taking several hostages including a school field trip. Diana storms the building, using the Lasso of Hestia to compel one of the terrorists to tell her their plans. He reveals that their leader has a bomb powerful enough to destroy several city blocks while the world media watches. Diana takes out the terrorists and neutralizes the bomb. The terrorist leader then tries to kill the hostages with a gun, but Diana protects the hostages by deflecting bullets with her bracelets.
"Honestly... I think we're gonna be dead way before that. And you know what? I don't mind. It's an honorable end. But we've gotta shut Steppenwolf down. Superman's a no-show. You've got no powers, no offense. This guy might be working for the enemy. We don't now. You're tripping over your feet, and mine... whuf, you're gorgeous, and fierce... and strong. I know we went to war with the Amazons, but that was before my time. You know what? I don't wanna die. I'm young. There's shit that I wanna do. I just feel like... I didn't really embrace the sea or the land. I've been a loner my whole life. But being part of something bigger, like this... maybe I'm scared because... I'm meant to..."
