Wonder Woman and Hermes briefly returned to Themyscira so that Diana could pay her respects to her petrified mother. When they got back to her apartment, they found Hera crying and mourning the days when she used to be a goddess. As Diana comforted her, she realized she would need help in finding Zola and Zeke. Wonder Woman went to the Taiga, Siberia, where she asked Artemis for her help. Artemis agreed, on the condition that she and Diana have a rematch. Knowing they are in Artemis' realm, Diana threw the fight in Artemis' favor.
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.
After the meeting, Trevor's superior berated him for taking a woman into the war room. Morgan then introduced himself to Diana. She began to introduce herself as "Diana, Princess of Themyscira," but Trevor cut her off to maintain her secret identity, calling her "Diana Prince." Trevor then informed Morgan that he'd managed to steal Doctor Poison's notebook.
One of the events that led to Infinite Crisis was of Wonder Woman killing the villain Maxwell Lord in Wonder Woman (vol. 2) #219. Maxwell Lord was mind-controlling Superman, who as a result was near to killing Batman. Wonder Woman tried to stop Superman, Lord (who was unable to mind control her) made Superman see her as his enemy Doomsday trying to kill Lois Lane. Superman then attacked Wonder Woman, and a vicious battle ensued. Buying herself time by slicing Superman's throat with her tiara, Wonder Woman caught Lord in her Lasso of Truth and demanded to know how to stop his control over Superman. As the lasso forced the wearer to speak only the truth, Lord told her that the only way to stop him was to kill him. Left with no choice, Wonder Woman snapped Lord's neck and ended his control over Superman. Unknown to her, the entire scene was broadcast live around every channel in the world by Brother Eye. The viewers were not aware of the entire situation, and saw only Wonder Woman murdering a Justice League associate. Wonder Woman's actions put her at odds with Batman and Superman, as they saw Wonder Woman as a cold-blooded killer, despite the fact that she saved their lives.
