Wonder Woman gets a little jealous with Supergirl's arrival, believing she is trying to catch everyone's attention. When she realized that Supergirl is actually a better superhero because she looks up to Wonder Woman, they became friends and Wonder Woman helps to train Supergirl. She is among the heroes to battle against Granny Goodness and the Female Furies. She is voiced by Grey Griffin.
A. O. Scott of The New York Times wrote that it "briskly shakes off blockbuster branding imperatives and allows itself to be something relatively rare in the modern superhero cosmos. It feels less like yet another installment in an endless sequence of apocalyptic merchandising opportunities than like ... what's the word I'm looking for? A movie. A pretty good one, too." Michael Phillips of Chicago Tribune compared the film to Captain America: The First Avenger, noting that as with "the first Captain America movie over in the Marvel Comics universe, DC's Wonder Woman offers the pleasures of period re-creation for a popular audience. Jenkins and her design team make 1918-era London; war-torn Belgium; the Ottoman Empire; and other locales look freshly realized, with a strong point of view. There are scenes here of dispossessed war refugees, witnessed by an astonished and heartbroken Diana, that carry unusual gravity for a comic book adaptation." Katie Erbland of IndieWire commended its thematic depth, explaining that "Wonder Woman is a war movie. Patty Jenkins' first—and we hope not last—entry into the DC Expanded Universe is primarily set during World War I, but while the feature doesn't balk at war-time violence, it's the internal battles of its compelling heroine that are most vital." Alonso Duralde of TheWrap similarly felt that, "Diana's scenes of action are thrilling precisely because they're meant to stop war, not to foment it; the idea of a demi-god using love to fight war might sound goofy in the abstract, but Jenkins makes the concept work." Ann Hornaday of The Washington Post praised Gadot and Pine's performances as well the film's detailed plot and narrative while comparing of some slow-motion action sequences to The Matrix. Stephanie Zacharek of Time magazine hailed the film as a "cut above nearly all the superhero movies that have been trotted out over the past few summers" while praising Gadot's performance as "charming" and "marvelous" and commending Jenkins's direction of the film as a step forward for women directors in directing big-budget blockbuster films in Hollywood.
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.
