Their first adventure together as a serious couple involved a battle with Doomsday, a monster of Kryptonian legend. Superman, already familiar to the monster, explained that Doomsday was sealed into a pocket dimension called the Phantom Zone. Seeking preparation against enemies that could match them in power, Wonder Woman asked Hephaestus to forge weapons for them. Later, the Justice League intercepted the arrival of General Zod, another Kryptonian survivor. Superman gave him shelter in the Fortress of Solitude, but the couple discovered their relationship was now public knowledge.
Born to Hippolyta, Queen of the Amazons, Diana lived a serene and joyful life until the intervention of Steve Trevor upon the island of Themyscira. A tournament was held among the Amazons to determine the representative that would return to Man's World along with Trevor. Diana defeated the other Amazons but was tasked with the final challenge, deflecting a bullet fired from a gun by her mother. After winning the contest Diana was awarded a suit of armor and the Lasso of Truth and left for the United States, though upon her arrival she was arrested and detained in a cell. Falling into despair, Diana was visited by the Gods of Olympus in their animal forms: a peacock, deer, owl, mouse, eagle, dove and tortoise, who granted her the gifts of strength, speed, endurance, empathy and flight.
The screenplay will be co-written by three people: Jenkins, Johns, and The Expendables writer Dave Callaham. Callaham’s involvement was revealed on Sept. 13, disappointing fans who hoped for another woman on the film’s core creative team. That being said, it seems that Callaham was personally recruited by Jenkins herself since they already worked together on a previous project.
In order to prove her devotion to her people, the Amazons issued a challenge to Diana, one she would have to meet in two days. In the meantime, the Justice League had tracked the insectoid queen down to a remote mountain. The League journeyed deep into the mountain and encountered the queen. Diana condemned her for the lives she has taken, but the insectoid queen replied that it was Diana’s actions, namely her throwing of the First Born into the depths of the Earth, that awoke the insectoids from their slumber.
After defeating Giganta in battle, Wonder Woman was approached by a lawyer who informed her that she had inherited the estate of Hercules, who had been killed. Shortly thereafter, she was told by A.R.G.U.S. that Hercules' body came from an area containing traces of energy unique to Apokolips. Diana visited Hercules' home and found a letter addressed to her, informing her of the location of her twin brother, Jason. She found him in Greece, and the two seemingly began to bond, only for Jason to turn against Diana after the arrival of Grail, who he had secretly allied himself with. Grail had begun killing children of the earthly gods in order to use their divine power to restore her father Darkseid to adulthood, as he had been turned into a baby at the end of the Darkseid War. Jason allied himself with her in order to exact revenge on Wonder Woman, as he resented her for not seeking him out after she learned of his existence some time ago and was envious of her. However, as Darkseid was about to drain Diana's life force, Jason regretted his actions and joined Wonder Woman in battle against Grail and Darkseid. Then, Hercules' lawyer revealed his true identity as the King of the Gods himself, Zeus. Zeus fought Darkseid while Wonder Woman took on his daughter, Grail. Ultimately, Zeus was defeated and his life force was drained by Darkseid, restoring the Apokoliptian to his full adult form. The Justice League arrived, forcing Darkseid and Grail to retreat through a Boom Tube. In the aftermath of the battle, Diana forgave her brother for his deceit.
As the daughter of Zeus, Wonder Woman has incredible control over the supernatural divine energy of the Olympian Gods, which she usually emits through her Bracelets of Submission. When she clashes her bracelets together, she releases a large spherical blast of orange (or sometimes white-hot) energy, with it being powerful enough to accidentally injure Antiope, send the mighty gods Ares and Steppenwolf flying back, and even push back the gigantic monster Doomsday. At full power, Wonder Woman could generate these shock waves from her body, notably to destroy the restrains Ares put her in and knock down a small German battalion with a very powerful omni-directional shock wave. She was also capable of using the energy to shield herself, as the debris Ares sent flying at her disintegrated against the invisible field as she built up her attack. She could also freeze the momentum of targets in front of her, causing Ares to be forcibly suspending in the air when he tried flying into her before she blasted him away. Wonder Woman can also transmit this energy through her shield. By striking one of her bracelets with her shield, she generated an energy wave that knocked down a bridge, and Cyborg and Steppenwolf with it.
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.
