While Diana stood admiring the replica, Bruce Wayne appeared. He proceeds to angrily confront her by grabbing Diana's arm and asking her about the information device that she had stolen. Bruce claims to see right through her "babe in the woods" act, saying that while Diana doesn't know him, he's met "a few women like [her]". Diana, however, calmly smiles and retorts that Bruce has never met any women like her. She then proceeds to tell Bruce that she was unable to obtain anything from Bruce's device, due to Lex Luthor's data having military-grade encryption. Diana explains her intention to re-obtain her photograph from Luthor, stating that she only borrowed Bruce's device, and has already returned it to him shortly beforehand (placing it into the glove compartment of his car), before calmly excusing herself and leaving.
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.
"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..."
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.
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.
