William Moulton Marston wanted to create a superhero that would fight with wits and wisdom rather than fists and muscle. His wife, Elizabeth, suggested that was a wonderful idea, so long as he made her a woman. Credited as Charles Moulton, Marston went about creating one of the most iconic women in the history of fiction.
In 2001 The Justice League, an animated show that had grown out of the success of Batman The Animated Series and Superman The Animated Series, made it’s debut. Featuring a line up of seven heroes, Batman, Superman, Wonder Woman, Green Lantern, The Flash, Hawkgirl and The Martian Manhunter, the show ran for two seasons and then was replaced with Justice League Unlimited. Justice League Unlimited ran for three seasons and featured the original seven heroes in tandem with dozens of other characters from the DC Universe.
Wonder Woman was voiced by Susan Eisenberg for all five seasons. The modern version of Wonder Woman was more of a warrior than her previous incarnations on television, occasionally wielding a sword and often expressing her frustration with “man’s world” with her fists. She had an ability not seen in previous television appearances, in that she could fly under her own power. She did still use her invisible jet, however.
There was an inferred but never seen relationship with Batman that was an element unique to the Justice League animated series. It would likely never have worked out, since as Batman puts it, “You’re a princess from a society of immortal warriors, I’m a rich kid with issues. Lots of issues.”
