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.
Upon becoming a super-heroine, Wonder Woman became a founding member of the Justice League. Her ambassadorial duties required her to visit Washington D.C., with army officer Steve Trevor as her liaison. When Parademons stormed Metropolis, Wonder Woman resolved to defend the city, meeting the heroes Superman, Batman, Flash, Green Lantern and Aquaman. They also met the young hero Cyborg, who attempted to warn them against the evil alien conqueror Darkseid. Unfortunately, Cyborg's warnings were meaningless, as Darkseid had already arrived. Although Darkseid had initially beat them without effort, Green Lantern rallied them in order to confront Darkseid as a team. Wonder Woman proved crucial in Darkseid's defeat, stabbing him in one of his eyes to prevent him from using his Omega Beams. This gave Superman and Cyborg enough time to throw Darkseid back into his home-world.
Born among the legendary Amazons of Greek myth Princess Diana has a fierce warrior's heart while being an emissary of peace. On a hidden island paradise she was trained in the arts of combat as well as justice and equality. Diana ventured into the 'world of men' armed with magical gifts from the Gods and a message for all men and women - that all the world can be united through compassion strength and understanding.
^ Greenberger p. 175: "Journalist and feminist Gloria Steinem...was tapped in 1970 to write the introduction to Wonder Woman, a hardcover collection of older stories. Steinem later went on to edit Ms. Magazine, with the first issue published in 1972, featuring the Amazon Princess on its cover. In both publications, the heroine's powerless condition during the 1970s was pilloried. A feminist backlash began to grow, demanding that Wonder Woman regain the powers and costume that put her on a par with the Man of Steel."
With a new decade arriving, DC president Jenette Kahn ordered a revamp in Wonder Woman's appearance. Artist Milton Glaser, who also designed the "bullet" logo adopted by DC in 1977, created a stylized "WW" emblem that evoked and replaced the eagle in her bodice and debuted in 1982. The emblem in turn was incorporated by studio letterer Todd Klein onto the monthly title's logo, which lasted for a year and a half before being replaced by a version from Glaser's studio. With sales of the title continuing to decline in 1985 (despite an unpublished revamp that was solicited), the series was canceled and ended in issue #329 (February 1986) written by Gerry Conway, depicting Steve Trevor's marriage to Wonder Woman.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
