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.
Veronica Cale employed the toxicologist Colonel Poison, who led Team Poison, a team that attempted to capture Diana and Steve. In order to protect Diana in her vulnerable state, Steve had her admitted to a mental hospital in London. Team Poison continued to pursue Steve, Barbara and Commander Etta Candy, however. Barbara, who had been a member of Godwatch when she was Cheetah, decided to speak to Veronica herself. Cale and Doctor Cyber showed Barbara footage of Team Poison, who were about to kill her friends, and Barbara agreed to become Cheetah again in exchange for Veronica calling off the team and sparing their lives.
Paquette detailed the changes he made to Wonder Woman's costume, stating that he removed the iconic American flag theme and instead incorporated a Greek influence: "The animal associated to Aphrodite is a dove so instead of an eagle on [Wonder Woman's] breastplate, it will be more of a dove. It's not the American eagle, it's the Aphrodite dove. Stuff that creates [the letter] W is by accident, so it's not like she already has a letter of the alphabet on her [costume]. In the end I've created a structure so it feels inevitable for Wonder Woman to look the way she does."
Superman begged his fellow heroes to arrest him, and while he was taken to the A.R.G.U.S. facilities, Diana expressed disapproval at Steve’s secret Justice League. Wonder Woman travelled to the Temple of Hephaestus and demanded Hephaestus tell her about what the box really was. Hephaestus answered that the box was not created by the Gods of Olympus and the truth was a mystery even to them. Wonder Woman decided to seek help from the Justice League Dark. Suddenly, the three Justice Leagues converged at the House of Mystery, where the heroes were divided, one side led by Wonder Woman, the other by Batman. Zatanna, having taken Wonder Woman’s side, teleported the group away. Wonder Woman’s group tracked Pandora’s box to Lex Luthor’s prison cell, where Pandora was offering the box to Luthor. Wonder Woman grabbed the box but was overwhelmed by its power.
Steve Rose in The Guardian criticized the film for failing to explore the material's potential for "patriarchy-upending subversion". Peter Travers of Rolling Stone criticized the film's over-reliance on exposition: "Wonder Woman is hobbled by a slogging origin story and action that only comes in fits and starts. Just when Gadot and director Patty Jenkins...are ready to kick ass, we get backstory."
Diana is depicted as a masterful athlete, acrobat, fighter and strategist, trained and experienced in many ancient and modern forms of armed and unarmed combat, including exclusive Amazonian martial arts. With her godlike abilities of incalculable superhuman strength, nigh-invulnerability, speed, flight, healing factor and semi-immortality, Diana’s fighting prowess is enhanced. In some versions, her mother trained her, as Wonder Girl, for a future career as Wonder Woman. From the beginning, she is portrayed as highly skilled in using her Amazon bracelets to stop bullets and in wielding her golden lasso. Batman once called her the "best melee fighter in the world". The modern version of the character is known to use lethal force when she deems it necessary. In the New 52 continuity, her superior combat skills are the result of her Amazon training, as well as receiving further training from Ares, the God of War, himself, since as early as her childhood. The Golden Age Wonder Woman also had knowledge in psychology, as did her Amazon sisters.
