The final remaining relics Darkseid needed were being guarded by A.R.G.U.S. at their HQ, so Darkseid decided to use a Boom Tube to transport the building and all its contents to his base in the Amazon Rainforest. The Female Furies retrieved the relics and put them into place while Wonder Woman fought Darkseid. With the relics' power, Darkseid was able to open a portal to Themyscira. As it is impossible for one who has set foot on Themyscira to return after leaving, Diana was unable to follow Grail through the portal. Grail invaded and began transforming the Amazons into creatures resembling Darkseid's Parademons. As Jason had never actually set foot on Themyscira, he followed Grail and met his mother Hippolyta for the first time since his birth. While Jason and Hippolyta fought off the transformed Amazons, Wonder Woman was able to defeat Darkseid through her love for her deceased father, Zeus, and her half-siblings, calling their spirits out of Darkseid's body and destroying him from the inside. The Amazons captured Grail and imprisoned her in the prison beneath Themyscira, alongside Ares, while Darkseid re-emerged somewhere on Earth. Jason was gifted a magical spear from his mother and returned to Earth.
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.
Using Bruce's equipment, Diana tries to track down Victor. Victor is aware of Bruce's interest in him; due to his connection to information and security systems, Victor hacks in the computers to send Diana a message. Diana suggests a meeting and when Victor asks why he should trust her, Diana tells him that she knew he was at the lake watching her and Bruce. If she meant to harm him, she would have done it then. Diana and Victor meet face to face, and he tells them that the invaders they are searching for are hiding in the dead zones. When Diana tries to convince him to join them, he flies off.
“Anniversary, which we forgot entirely,” Olive Byrne wrote in her secret diary in 1936. (The diary remains in family hands.) During the years when she lived with Marston and Holloway, she wore, instead of a wedding ring, a pair of bracelets. Wonder Woman wears those same cuffs. Byrne died in 1990, at the age of 86. She and Holloway had been living together in an apartment in Tampa. While Byrne was in the hospital, dying, Holloway fell and broke her hip; she was admitted to the same hospital. They were in separate rooms. They’d lived together for 64 years. When Holloway, in her hospital bed, was told that Byrne had died, she sang a poem by Tennyson: “Sunset and the evening star, / And one clear call for me! / And may there be no moaning of the bar, / When I put out to sea.” No newspaper ran an obituary.
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.
Master Combatant: Wonder Woman, having been trained in combat tactics by Menalippe and Antiope, is a tremendously skilled, fierce, and formidable hand-to-hand combatant (being at least on par with Batman), a master of a vast array of unique Amazonian martial arts, as well as an expert in most types of melee weapons (though she most frequently uses her bracelets, lasso, sword, and even shield). She has centuries of combat experience, with her claiming to have fought and defeated several beings from "other worlds" (which includes even the fearsome God of War Ares himself). Wonder Woman swiftly became the greatest warrior of Themyscira, her tremendous combat skills eventually becoming enough to rival even those of her mentor Antiope and ultimately surpassing her upon acquiring full potential, due to the latter (upon Hippolyta's insistence) training her much harder than any Amazon ever before her. Hence, Wonder Woman defeated the notorious Slipknot with effortless ease, as well as many World War I soldiers (she defeated and killed even the enhanced General Ludendorff relatively quickly), and numerous Parademons single-handedly, seamlessly incorporating hand-to-hand combat, sword-fighting with the God Killer (and later with the Sword of Athena), and the Lasso of Hestia in her own personalized, formidable style. Indeed, Wonder Woman's tremendous skill and exceptionally versatile style make her capable of effectively holding her own against either more experienced or more powerful opponents, even the mighty God of War Ares (albeit only with considerable effort and initial failure, given his superior combat experience, and her need to use a non-violent mindset), the New God Steppenwolf, an enraged resurrected Superman, and the gigantic Doomsday, with her managing to temporarily knock the latter fearsome monster down (by smashing his feet from under him with her shield), and even temporarily restrain him with her Lasso of Hestia, as well as cut off his right arm with the Sword of Athena. Indeed, had Doomsday not had his incredibly adaptable healing factor, it is safe to assume that Wonder Woman's tremendous combat skills would have allowed her to ultimately defeat him. Moreover, even when Wonder Woman's sword was destroyed by Ares, she still held her own against the more powerful Old God. However, although she put up a considerable fight, Wonder Woman was ultimately fairly quickly defeated by the resurrected Superman, and was only saved by Lois Lane's timely intervention.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
