Ares told Diana that he had been imprisoned by the other Gods of Olympus and bound in chains that were secured by Aphrodite through the power of her love. He also told her that years ago, Phobos and Deimos had implanted false memories of Themyscira into her mind, and these had caused her to imagine aspects of her past that had never happened in reality. Meanwhile, Phobos and Deimos entered Themyscira and battled with the Amazons. Diana knew what she had to do, and called Ares to unite her with Phobos and Deimos. He teleported them to her, and using her Lasso of Truth, Wonder Woman bound them through the power of her unconditional love for them, as Aphrodite had done to Ares. With the twin gods defeated, Diana attempted to leave Ares' prison along with Veronica and Izzy, however Izzy's essence had been attached to the realm and could not return to Earth. Izzy was forced to either live out the rest of her days in the prison or live in Themyscira as an Amazon for eternity. She chose the latter and Veronica said goodbye to her daughter. Diana was briefly reunited with her mother, for the first time since she left the island.
Straczynski's run focused on an alternate timeline created by the Gods where Paradise Island was destroyed leading to many Amazons being raised in the outside world. It revolves around Wonder Woman's attempts to restore the normal timeline despite the fact that she does not remember it properly. Wonder Woman in this alternative timeline has been raised in New York City as an orphan and is coming into her powers. She is aware of the presence of Amazons, but does not remember her childhood on Paradise Island. Wonder Woman wore a new costume designed by DC Comics co-publisher Jim Lee. Writer Phil Hester continued the storyline.
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.
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.
The Invisible Plane appeared in the very first comic stories, including All-Star Comics #8, where it is shown as being able to fly at over 2,000 mph (3,200 km/h) and to send out rainbow rays that penetrate the mist around Paradise Island, as well as landing stealthily and having a built-in radio. Wonder Woman is seen storing the plane at an abandoned farm near Washington, D.C., in the barn; she goes there as Lt. Prince and changes clothes in some of the earliest tales. Though never explicitly stated, the Plane is presumably stored there when not in use for the rest of the Pre-Crisis era. In a story published shortly after, it flies at 40 miles (64 km) a second.
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
