The Lasso of Truth, or Lasso of Hestia, was forged by Hephaestus from the golden girdle of Gaea. The original form of the Lasso in the Golden Age was called the Magic Lasso of Aphrodite. It compels all beings who come into contact with it to tell the absolute truth and is virtually indestructible; in Identity Crisis, Green Arrow mistakenly describes it as "the only lie detector designed by Zeus." The only times it has been broken were when Wonder Woman herself refused to accept the truth revealed by the lasso, such as when she confronted Rama Khan of Jarhanpur, and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity. During the Golden Age, the original form of the Lasso had the power to force anyone caught to obey any command given them, even overriding the mind control of others; this was effective enough to defeat strong-willed beings like Captain Marvel. Diana wields the Lasso with great precision and accuracy and can use it as a whip or noose.
As one of the longest continually published comic book characters, Wonder Woman’s history has undergone some changes over the years, though a few elements remain consistent in all of her depictions. She is the princess of the Amazons, a race of women who live free of men on Paradise Island (later dubbed Themyscira). After growing up on this island, Wonder Woman (whom her mother named Diana) journeys to Man’s World on a mission of diplomacy, peace, and love.
Although she initially forbids Diana to be trained as a warrior, Hippolyta reluctantly agrees to let General Antiope, Hippolyta's sister and Diana's aunt, train her, only more rigorously than any other warrior. In 1918, Diana, now a young woman, rescues US pilot Captain Steve Trevor when his plane crashes off the Themysciran coast. The island is soon invaded by German soldiers that had been pursuing Trevor. The Amazons kill the crew, but Antiope sacrifices herself to save Diana. Steve is interrogated with the Lasso of Hestia and reveals that a great war is consuming the outside world and that he is an Allied spy. He has stolen a notebook of the chief chemist Dr. Isabel Maru, who is attempting to engineer a deadlier form of mustard gas under the orders of General Erich Ludendorff from a weapon facility in the Ottoman Empire. Believing Ares to be responsible for the war, Diana arms herself with the "Godkiller" sword, the lasso, and armor before leaving Themyscira with Steve to locate and stop Ares for good.
In the issue's most surprising twist, made clear in this preview, is that the comic will begin after Diana's battle with the Dark Gods. Parting ways with Steve Trevor after the battle isn't a shock, since fans expect it to be a big, future-altering showdown for Diana (and potentially even more humans). But the fact that the future of Jason is left unclear may be the biggest tease.
Steppenwolf then grabs Silas Stone, which Cyborg shots Steppenwolf and saves his father, and Wonder Woman helps out by attacking the Parademons and taking Steppenwolf to a different part of the factory. While Batman fights the Parademons, Barry goes and save one of the employees. Steppenwolf tells the Parademons that he will deal with Diana alone; meanwhile, Batman is being attacked by one of the Parademons as he tells Alfred that he needs the Knightcrawler, which he sent the machine to Bruce.
Born among the legendary Amazons of Greek myth Princess Diana has a fierce warrior's heart while being an emissary of peace. On a hidden island paradise she was trained in the arts of combat as well as justice and equality. Diana ventured into the 'world of men' armed with magical gifts from the Gods and a message for all men and women - that all the world can be united through compassion strength and understanding.
She asked him who he was, but before he could answer, the two noticed several boats coming through the island's forcefield. Steve noted that he was one of the good guys and the people on the boats—Germans—were bad guys. Having noticed the invading ships, the Amazons quickly gathered on the cliffs above the beach. Hippolyta ordered Trevor to move away from Diana, but forgot about him as the German soldiers began to come closer to shore. She took command of her army, ordering the archers to fire on the boats. Diana and Trevor took cover behind boulders on the beach.
After the fight with Steppenwolf, Batman meets with Gordon before Arthur shows up and say that Steppenwolf took the Mother Box from Atlantis, then Victor reveals that he is possession of the final Mother Box, which he hid from his father. The team returns to the Batcave which Barry runs around the cave and sits in the Batmobile, before Bruce call for a meeting with the team. Bruce states they should use the Mother Box to bring Superman back to life believing that they need Superman to restore hope in humanity. Diana and Arthur are hesitant about the idea, but Bruce forms a secret contingency plan. The team put Clark's body in the waters of the Kryptonian ship, using Allen's Speed Force energy to activate the Box, causing the resurrection of Superman.
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
