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.
Many of the Olympian Gods have made appearances on the Justice League and Justice League Unlimited animated series.

Wonder Woman's powers and traditional costume were restored in issue #204 (January–February 1973). Gloria Steinem, who grew up reading Wonder Woman comics, was a key player in the restoration. Steinem, offended that the most famous female superheroine had been depowered, placed Wonder Woman (in costume) on the cover of the first issue of Ms. (1972) – Warner Communications, DC Comics' owner, was an investor – which also contained an appreciative essay about the character.
Superhuman Speed: Wonder Woman, while not as fast as Superman or the Flash, can move at inhuman speeds. She was able to make it from the Metropolis Airport to Gotham Port in minutes after seeing Doomsday on television. She was fast enough to get up from her seat, disarm a man of his gun, and toss him across a room in seconds; to leave Lex Luthor's fundraiser before Bruce managed to reach her; to save Batman from Doomsday's thermal attack; and to instantly use the Sword of Athena to slice apart in mid-air a car that Doomsday hurled at her. Indeed, Wonder Woman appeared as a blur when charging back at Doomsday after being knocked back by him. She was also capable of landing blows on Superman, even though she was outmatched.
After a training session, Diana happened to come across Captain Steve Trevor during his escape from the Imperial German Army. A battle soon followed, as the Germans tracked Trevor to Themyscira, where they invaded in pursuit of Doctor Poison's notes. The loss of her aunt and realization of Mankind's downfall during the absence of the amazons convinced Diana to join the war effort, recognizing Ares as the instigator of the conflict.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
