Trevor was taken to be interrogated using the Lasso of Hestia. Though he tried to resist the lasso's power at first, unwilling to reveal military secrets, he nonetheless was powerless to withstand it and admitted that he was a spy. He told them that he'd been on a mission to observe General Ludendorff and Doctor Poison, that he'd stolen the latter's research notebook, and that his escape had brought himself and the Germans to Themyscira. He described the Great War, informing them that millions of people had died. Hearing this, Diana deduced that only Ares could be behind a war of that magnitude. She tried to persuade Hippolyta to send the Amazons back with him to face the god, but her mother refused, much to Diana's confusion.
Voiced by Michelle Monaghan. Based on the story ''Justice League Origins'', where Darkseid invades earth, only to fail due to its heroes. Wonder Woman is first seen with Steve Trevor, where she is supposed to meet the president of the United States, but he isn't there. After the Mother Boxes opens up boomtubes, she defeats multiple soldiers of Apokolips, but flies to Air Force One to protect the president. After battling some opponents, she meets Superman, and from there they proceed to meet other heroes. The battle and Superman gets knocked out and is about to be made a soldier by Desaad but Batman manages to save him in time. Wonder Woman then proceeds to battle Darkseid along with the rest of the Justice League, and succsessfully sends him back throug a boomtube.
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.
