Before Steppenwolf could kill Cyborg, Superman comes and saves him, by easily overpowering the New God. Bruce tells Superman he needs to buy Cyborg some time to separate the Mother Boxes and to help civilians, Superman catches up with Barry, saying he got the ones on the right. After subduing Steppenwolf again, Victor calls Superman for help with the Mother Boxes. Steppenwolf is not down yet and tries to attack, but Superman freezes Steppenwolf's Axe and Diana breaks it with her Sword, which finally leads to Steppenwolf realizing he has been defeated and is overwhelmed with fear for the first time. He is attacked by his own Parademons before he returns back to Apokolips.
Earning a total of $103.3 million on its opening weekend, the film recorded a number of records: the biggest domestic opening of all time for a female director (surpassing previous record holder Fifty Shades of Grey), the biggest DC Comics release without Batman or Superman (ahead of Constantine), the sixth-biggest non-sequel comic book superhero debut ever, as well as the sixth-biggest June debut weekend. Its three-day opening alone made it the highest-grossing woman-led comic book superhero film ever (surpassing Ghost in the Shell). It was also the 16th superhero film to cross $100 million in its domestic box office launch. About 9% ($9 million) of the opening weekend came from IMAX screenings from 343 theaters. In its second week the film grossed $58.5 million, again topping the box office. It marked a 43.3% drop for its second weekend at the box office, better than the average 50–60% decline superhero films tend to see, and was a better second weekend than Batman v Superman: Dawn of Justice ($51.3 million) and Suicide Squad ($43.5 million). In its third weekend it grossed $40.8 million, finishing second behind newcomer Cars 3 ($53.5 million). It was the second-best third weekend ever for Warner Bros. and was nearly double what Batman v Superman ($23.3 million), Suicide Squad ($20.9 million) and Man of Steel ($20.7 million) made in their third weekends. It earned $24.9 million and $15.7 million in its fourth and fifth weekends, respectively, dropping just 39% and 36% despite facing rough competition from opening films Transformers: The Last Knight and Despicable Me 3. It eventually became the highest-grossing film directed by a woman, surpassing the previous records of Jennifer Yuh Nelson's Kung Fu Panda 2 and Phyllida Lloyd's Mamma Mia!. By August 8, the film had garnered $400 million in ticket sales, becoming the second female-fueled film (after Disney's Beauty and the Beast), Warner Bros.' third-biggest movie (after Christopher Nolan's The Dark Knight and The Dark Knight Rises), holding the record of the highest-earning superhero origin film, replacing the previous record held by Spider-Man (2002). It also becoming the highest-earning film with a female director in terms of domestic earnings—surpassing Frozen (2013).
Stealth Expert: Wonder Woman is exceptionally stealthy, as she was able to quickly sneak away from Chief and Charlie to General Ludendorff's gala, and later to steal the hacking device that Bruce Wayne had plugged into the LexCorp Industries servers and leave it in his car, without getting caught on either occasion. Later, Wonder Woman noticed Cyborg spying on her and Batman from a distance. Shortly thereafter, along with Batman and Cyborg, she was able to swiftly slip away when Commissioner Gordon turned away for a moment, and even Flash was left incredulous at how he didn't notice his teammates leave, despite having superhuman reflexes and standing right beside them. Wonder Woman even managed to enter the highly-secure Batcave itself on her own, impressing Batman.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
