By the end of the war, Diana began to lose faith in both humanity and herself after Ares opened her eyes to humanity's potential for evil. While she still believed in the power of love and compassion to change humanity for the better, Diana was left sobered and emotionally broken over certain events from the war, such as the use of Dr. Poison's gas to massacre the entire village of Veld, and Steve Trevor's self-sacrificing death. After witnessing a "century of horrors", Diana largely stepped away from heroics until she witnessed the seemingly unstoppable Doomsday wreck havoc; ultimately joining in to battle him alongside Batman and Superman. After witnessing Superman's own sacrifice to stop the monster, however, Diana turned once again towards heroics; demonstrating not only her underlying belief in her own core values, but also in the positive effect true heroes can have on the world.
Following Crisis on Infinite Earths, Wonder Woman was rebooted in 1987, by writer Greg Potter, who previously created the Jemm, Son of Saturn series for DC, was hired to rework the character. He spent several months working with editor Janice Race on new concepts, before being joined by writer/artist George Pérez. Inspired by John Byrne and Frank Miller's work on refashioning Superman and Batman, Pérez came in as the plotter and penciler of Wonder Woman. Potter dropped out of writing the series after issue #2, and Pérez became the sole plotter. Initially, Len Wein replaced Potter but Pérez took on the scripting as of issue #18. Mindy Newell would return to the title as scripter with issue #36 (November 1989). Pérez produced 62 issues of the rebooted title. His relaunch of the character was a critical and sales success.
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.
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.
