On November 3, 2016, Rupert Gregson-Williams was hired to write and compose the film's music. He was joined by Evan Jolly, Tom Howe, Paul Mounsey, and Andrew Kawczynski, who provided additional music. The soundtrack was released on CD, digital, and vinyl the same day as the film. Australian musician Sia sang a song for the film, titled "To Be Human", featuring English musician Labrinth. Written by Florence Welch and Rick Nowels, the track is also featured on the soundtrack. The soundtrack also features samples from Wonder Woman's theme "Is She with You" from the Batman v Superman: Dawn of Justice soundtrack composed by Hans Zimmer and Junkie XL.
The story then focuses on Wonder Woman's quest to rescue Zola from Hades, who had abducted her and taken her to Hell at the end of the sixth issue of the series. The male children of the Amazons are introduced and Diana learns about the birth of her "brothers" – the Amazons used to infrequently invade ships coming near their island and force themselves on the sailors, before killing them. After nine months, the birth of the resulting female children was highly celebrated and they were inducted into the ranks of the Amazons while the male children were rejected. In order to save the male children from being drowned to death by the Amazons, Hephaestus traded weapons to the Amazons in exchange for them.
Wonder Woman and Hermes briefly returned to Themyscira so that Diana could pay her respects to her petrified mother.

Wonder Woman went to the Taiga, Siberia, where she asked Artemis for her help. Artemis agreed, on the condition that she and Diana have a rematch. Knowing they are in Artemis' realm, Diana threw the fight in Artemis' favor.

Aquaman has also had run-ins with the Olympian sea deities. Poseidon had long relinquished the title of Sea King to Orin of Atlantis, but when Aquaman's subjects lost faith in him, Poseidon arranged a challenge with his son Triton. Aquaman bested Triton and the godling fell from grace with his father. In anger, Triton slayed Poseidon and claimed his power. Aquaman freed Poseidon by appealing to Lord Hades. When they returned from the dead, Poseidon slew his son in turn. Disgusted with mortal affairs, Poseidon bequeathed his trident to Aquaman. Aquaman somehow lost the Trident, though, as it was last seen with Queen Clea.
Pérez and Potter wrote Wonder Woman as a feminist character, and Pérez's research into Greek mythology provided Wonder Woman's world with depth and verisimilitude missing from her previous incarnation. The incorporation of Greek gods and sharply characterized villains added a richness to Wonder Woman's Amazon heritage and set her apart from other DC heroes.
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.
