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.
The Invisible Plane was a creation of Diana's during her younger years on Paradise Island. She created it to be an improvement on her mother's planes which would be shot down in Man's World. The result of her innovation was an invisible plane that could fly at terrific speeds silently and not be detected by hostile forces. Initially, it was portrayed as being transparent.
Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
Superhuman Durability: The bones and muscles of Wonder Woman are much denser and harder than those of humans and Amazons, which makes her incredibly durable. Although she is not bulletproof, she can survive brute force trauma, falls from high altitudes, explosions and powerful bursts of energy, or come in contact with superhuman opponents such as Ares, Doomsday, Steppenwolf and Superman. While training with the other Amazons, Wonder Woman was not affected by the attacks of the latter, not even by the attacks of strong Amazons like Antiope and Artemis, as well as by resisting the blows of the improved Erich Ludendorff without any damage. Wonder Woman's durability allowed her to withstand Ares's blows, despite the considerably greater strength of the God of War, as well as a direct hit from a sword built by Ares, an explosion of lightning that blew it away and left her somewhat dazed, and even a tremendous explosion that left her dazed and almost deaf for a few minutes and still was able to get up to fight again against her half brother. After reaching her full potential as a demigoddess, the Wonder Woman became considerably more durable, enough to withstand the huge blows of the Doomsday monster, with a blow sending her flying several meters and leaving her completely unharmed. It was also able to withstand the lightning, thermal vision and waves of electrical discharges of Doomsday, wrapped by the thick thermal beam without suffering any damage. In the same way, Wonder Woman came out completely unscathed and without a scratch from her fierce battles with Steppenwolf and Superman, even though Steppenwolf hit her constantly with her Electro Ax and Superman hit her with enough force to leave her dazed. While Wonder Woman may be affected by the considerable force of the powerful impacts, they only make her stumble and hit her briefly, leaving her unharmed, with Wonder Woman smiling even after receiving powerful blow from Doomsday that sent her flying, and quickly rose up to face the monster again with a renewed ferocity.
Princess Diana commands respect both as Wonder Woman and Diana Prince; her epithetical title – The Amazon Princess – illustrates the dichotomy of her character. She is a powerful, strong-willed character who does not back down from a fight or a challenge. Yet, she is a diplomat who strongly "favors the pen", and a lover of peace who would never seek to fight or escalate a conflict. She's simultaneously both the most fierce and most nurturing member of the Justice League; and her political connections as a United Nations Honorary Ambassador and the ambassador of a warrior nation makes her an invaluable addition to the team. With her powerful abilities, centuries of training and experience at handling threats that range from petty crime to threats that are of a magical or supernatural nature, Diana is capable of competing with nearly any hero or villain.
Antiope's lieutenant and Diana's aunt. Describing her character, Kongsli said "Menalippe is a fearless warrior with a strong justice needs. She lives with the other Amazons on the island Themyscira and exercising continuous battle to assist man in the fight for the good." On filming, Kongsli stated, "It's a blast. I've worked damn hard to make this happen, so it's absolutely absurd and fun all at once."
The girl who wondered has seen wonders... has become a woman who has traveled the world, who has traveled worlds! A woman who has touched countless lives, has made them better in ways beyond measure. A woman who has brought hope, and joy, and love. A woman who is the hero of so many. The truth of you has never changed, Diana. Even the gods themselves could not take that from you. Why would we? It's one of the many reasons we love you.
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.
