The I Ching era had an influence on the 1974 Wonder Woman TV movie featuring Cathy Lee Crosby, in which Wonder Woman was portrayed as a non-superpowered globe-trotting super-spy who wore an amalgam of the Wonder Woman and Diana Prince costumes. The first two issues of Allan Heinberg's run (Wonder Woman vol. 3, #1–2) include direct references to I Ching, and feature Diana wearing an outfit similar to that which she wore during the I Ching era.
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.
After taking on the mantle God of War after killing her mentor War. Diana have shown some new abilities. She can now telepathically communicate and control all soldiers on the planet since she is their greatest leader. She hasn't shown the ability, but as her predecessor was able to bring back dead soldiers to fight alongside him, she might be able to do so as well.
With Wonder Woman arriving in pursuit, Strife warned of the prophecy Apollo and Artemis feared: a child of Zeus would kill a god to take the throne. That child could be either Diana or Zola's child. Sending Zola back with Hermes to have her baby in peace, Diana warned that if they were not left alone, she would fulfil the prophecy herself. Unfortunately, upon her return to Michigan, Diana found that Hermes had betrayed them, and once Zola gave birth to her son, he whisked the child away, and gave it to Demeter. Diana swore to get the boy back and bring Hermes to justice.
Following the Rebirth retcon, the "Year One" storyline explains that while put in a cell after coming to Man's World, Diana was visited by the Greek gods in animal form. Each gave her powers that would reveal themselves when she needed them to. She first displays strength when she accidentally rips the bars off her cell door when visited by Steve Trevor, Etta Candy, and Barbara Ann Minerva. Later on a trip to the mall, she discovers super speed, great durability, and the power of flight while fighting off a terrorist attack.
^ Greenberger p. 175: "Journalist and feminist Gloria Steinem...was tapped in 1970 to write the introduction to Wonder Woman, a hardcover collection of older stories. Steinem later went on to edit Ms. Magazine, with the first issue published in 1972, featuring the Amazon Princess on its cover. In both publications, the heroine's powerless condition during the 1970s was pilloried. A feminist backlash began to grow, demanding that Wonder Woman regain the powers and costume that put her on a par with the Man of Steel."
