The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
Nick Pumphrey stated that Wonder Woman stands as a non-violent beacon of hope and inspiration for women and men. Grant Morrison stated "I sat down and I thought, 'I don't want to do this warrior woman thing.' I can understand why they're doing it, I get all that, but that's not what [Wonder Woman creator] William Marston wanted, that's not what he wanted at all! His original concept for Wonder Woman was an answer to comics that he thought were filled with images of blood-curdling masculinity, and you see the latest shots of Gal Gadot in the costume, and it's all sword and shield and her snarling at the camera. Marston's Diana was a doctor, a healer, a scientist."
As Wonder Woman joins the Battle against Doomsday, she arrives just in time to save Batman from Doomsday's lethal thermal blast, deflecting the beams with her indestructible bracelets. She then jointly attacks Doomsday with Superman while Batman tries to expose the creature to Kryptonite, allowing its destruction. She relentlessly battles the monster, and despite Doomsday being stronger, Wonder Woman held her own, parrying a tremendous punch with the Sword of Athena, and then slicing off Doomsday's right arm with it. Eventually, Batman baits the monster into coming closer to her, allowing Wonder Woman to hurl the noose of her unbreakable Lasso of Hestia around his torso.
Wonder Woman was legally barred from appearing in the first few seasons of the Batman: The Brave and the Bold, but made a cameo from behind in the episode "Sidekicks Assemble!" She later made a full appearance in the final season during the episode "Scorn of the Star Sapphire!," and played a main role in the episode "Triumvirate of Terror!" In the show, she was voiced by Vicki Lewis.
Superhuman Speed: Wonder Woman, while not as fast as Superman or the Flash, can move at inhuman speeds. She was able to make it from the Metropolis Airport to Gotham Port in minutes after seeing Doomsday on television. She was fast enough to get up from her seat, disarm a man of his gun, and toss him across a room in seconds; to leave Lex Luthor's fundraiser before Bruce managed to reach her; to save Batman from Doomsday's thermal attack; and to instantly use the Sword of Athena to slice apart in mid-air a car that Doomsday hurled at her. Indeed, Wonder Woman appeared as a blur when charging back at Doomsday after being knocked back by him. She was also capable of landing blows on Superman, even though she was outmatched.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
