When she is preparing for the final game (Teaming up with Supergirl, Starfire, Bumblebee and Batgirl against Lobo, Maxima, Bleez, Mongal and Blackfire), the competition is interrupted by Lena Luthor. Wonder Woman starts putting civilians safe, including the Embassador, who, out of fear, orders her to star with him to protect him. She refuses and returns to the batlle, angering the Embassador. She fight Lena and then Brainiac. Upon their defeat, Wonder Woman rejoins with her mother, thinking she dissapointed her by no following the Embassador orders, but Hippolyta is proud instead, stating that Wonder Woman will be an amazing Queen.
Flash and Cyborg save all the hostage, which Silas Stone tells Victor that Steppenwolf can not get the final Mother Box. Batman then jumps down into the Knightcrawler and saves Wonder Woman after a Parademon manages to briefly knock her out. The Knightcrawler gets attacked by Steppenwolf, and Barry helps Wonder Woman get her sword so she can help Batman.
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
Wonder Woman (vol. 1) #179 (Nov. 1969) showed Wonder Woman giving up her powers and returning her costume and title to her mother, in order to continue staying in Man's World. The reason behind this was that all the Amazons were shifting to another dimension, but Diana was unable to accompany them as she needed to stay behind to help Steve, who had been wrongly convicted. Thus, she no longer held the title of Wonder Woman and after meeting and training under a blind martial arts mentor I-Ching, Diana resumed crime fighting as the powerless Diana Prince. She ran a mod-boutique as a business and dressed in a series of jumpsuits while fighting crime. During this period, Samuel R. Delany took over scripting duties with issue #202. Delany was initially supposed to write a six-issue story arc, which would culminate in a battle over an abortion clinic, but Delany was removed reportedly due to criticism from Gloria Steinem, who, not knowing the content of the issues Delany was writing, was upset that Wonder Woman had lost her powers and was no longer wearing her traditional costume.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
