Shortly after the team assembled, Wonder Woman assisted in helping a newly resurrected Superman regain his memories. With the team now fully assembled, Wonder Woman contributed to the successful offensive against Steppenwolf, forcing the alien invasion into retreat. Afterwards, she began to plan for the Justice League's future alongside Bruce Wayne.
While Diana stood admiring the replica, Bruce Wayne appeared. He proceeds to angrily confront her by grabbing Diana's arm and asking her about the information device that she had stolen. Bruce claims to see right through her "babe in the woods" act, saying that while Diana doesn't know him, he's met "a few women like [her]". Diana, however, calmly smiles and retorts that Bruce has never met any women like her. She then proceeds to tell Bruce that she was unable to obtain anything from Bruce's device, due to Lex Luthor's data having military-grade encryption. Diana explains her intention to re-obtain her photograph from Luthor, stating that she only borrowed Bruce's device, and has already returned it to him shortly beforehand (placing it into the glove compartment of his car), before calmly excusing herself and leaving.
Vox stated "Trevor is the superhero girlfriend comic book movies need". The San Francisco Chronicle's Mick LaSalle lauded the performances of Gadot, Pine, Huston, and Thewlis while commending the film's "different perspective" and humor. Richard Roeper of Chicago Sun-Times described Gadot's performance as inspirational, heroic, heartfelt and endearing and the most "real" Wonder Woman portrayal.
Writer Gerry Conway brought Steve Trevor back to life again in issue #271 (September 1980). Following Diana's renunciation of her role as Wonder Woman, a version of Steve Trevor from an undisclosed portion of the Multiverse accidentally made the transition to Earth-One. With Diana's memory erased by the Mists of Nepenthe, the new Steve again crash-landed and arrived at Paradise Island. After reclaiming the title of Wonder Woman, Diana returned to Military Intelligence, working with Trevor and re-joined by supporting characters Etta Candy and General Darnell.
Gaines decided he needed another expert. He turned to Lauretta Bender, an associate professor of psychiatry at New York University’s medical school and a senior psychiatrist at Bellevue Hospital, where she was director of the children’s ward, an expert on aggression. She’d long been interested in comics but her interest had grown in 1940, after her husband, Paul Schilder, was killed by a car while walking home from visiting Bender and their 8-day-old daughter in the hospital. Bender, left with three children under the age of 3, soon became painfully interested in studying how children cope with trauma. In 1940, she conducted a study with Reginald Lourie, a medical resident under her supervision, investigating the effect of comics on four children brought to Bellevue Hospital for behavioral problems. Tessie, 12, had witnessed her father, a convicted murderer, kill himself. She insisted on calling herself Shiera, after a comic-book girl who is always rescued at the last minute by the Flash. Kenneth, 11, had been raped. He was frantic unless medicated or “wearing a Superman cape.” He felt safe in it—he could fly away if he wanted to—and “he felt that the cape protected him from an assault.” Bender and Lourie concluded the comic books were “the folklore of this age,” and worked, culturally, the same way fables and fairy tales did.
Wonder Woman’s powers are a result of the blessings she received from the gods (or presumably in the modern version by her divine ancestry), but originally came from her "brain energy" training. Her abilities in large part come from her upbringing in the martial society of the Amazons. She is one of the most powerful superheroes in the DC universe.
It was later retconned by Gail Simone that Wonder Woman's outfit design had Amazonian roots. During a flashback in Vol. 3, Hippolyta is shown issuing orders to have a garment created for Diana, taking inspiration from the skies on the night Diana was born; a red hunter's moon and a field of stars against deep blue, and the eagle breastplate being a symbol of Athena's avian representations.[volume & issue needed]
