The "Diana Prince" identity has been part of Wonder Woman's history since her comics debut in 1941. In the early Golden Age stories, Wonder Woman served as a military secretary during World War II, using Prince as her cover. Later occupations Wonder Woman performed as Prince included translator at the United Nations, Air Force captain and ambassador, and in the '70s TV series, Lynda Carter's Wonder Woman used Prince to serve as an agent of the Inter-Agency Defense Command. In the DC Extended Universe, Prince works as curator for the Department of Antiquities at the extremely prestigious Louvre Museum and is held in very high esteem by the curator of the Gotham City Museum of Antiquities. Her tremendously long life span, accumulation of immense amount of knowledge and exceptional perceptiveness makes Diana Prince the wisest and most emotionally-intelligent member of the Justice League.
After taking Despero to the authorities, Wonder Woman and Superman came across the mysterious Pandora, someone Wonder Woman was familiar with. She believed Superman could use her box to trap the evil she unleashed in ancient times; but when Superman touched it, he was overwhelmed by its power. While Pandora took the box and left, the two heroes received news that a new superhuman, Shazam, was entering the borders of Kahndaq. Their confrontation with Shazam turned violent until the rest of the Justice League and the Justice League of America intervened to defuse the situation. Suddenly, Dr. Light lost control of his powers and began absorbing Superman's solar energy, unleashing an energy beam at Wonder Woman. In a fit of anger, Superman killed Dr. Light with his heat vision, an action that caused a fight between the two Leagues.
Granted by Athena (Goddess of Wisdom), this gives her a degree of wisdom beyond that of most mortals and gives her a strong moral sense. Originally in the Golden Age, her wisdom primarily consisted of her deep knowledge of, and ability to navigate through, human emotions. When she first showed up in Man’s World, she learned enough English language to converse with others in a few hours only. This also aids her in her tactical ability. She is among the smartest and wisest members of the Justice League of America, along with the Martian Manhunter and Batman.
Shortly after coming to the outside world, Diana interrupted a terrorist attack and was named "Wonder Woman" by the press. She continued to use her gifts to fight for peace and justice in Man's World. She later fought who she thought to be Ares, though in truth it was Phobos and Deimos who were disguised as their father. Fearing that she would eventually discover the truth and free Ares from his prison beneath Themyscira, the Gods of Olympus sent Phobos and Deimos to erase all memory of Themyscira from Diana's mind. The twin gods were unable to erase the memory, so instead they later implanted false memories regarding her home to deceive Diana, leading to a completely separate origin story and causing her to hallucinate new adventures. Diana was unaware that her memories had been tampered with, and believed the falsifications until her search for the truth led her to Ares himself years later.
Wonder Woman and Hermes briefly returned to Themyscira so that Diana could pay her respects to her petrified mother. When they got back to her apartment, they found Hera crying and mourning the days when she used to be a goddess. As Diana comforted her, she realized she would need help in finding Zola and Zeke. 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.
In order to defeat them, Superman and Wonder Woman collected the magic armor created by Hephaestus and intercepted Zod and Faora while they were building a portal to the Phantom Zone. At first, they defeated Zod and Faora by detonating their armor at point-blank range, but Zod and Faora were revitalized by a beam of sunlight sent by Apollo, which gave the criminals enough strength to beat Superman and Wonder Woman and trap them in an abandoned nuclear reactor. As a last-ditch effort to stop their enemies, Superman and Wonder Woman caused a nuclear explosion, but not before Clark told Diana that he loved her. The explosion trapped Zod and Faora back in the Phantom Zone, and Superman shielded Wonder Woman with his cape. The two heroes barely survived the explosion and Superman took Diana to Hessia, who used a healing crystal to save her.
Candy helped Diana try on a great many outfits until she finally settled on one. Dissatisfied, thinking that she still looked too "distracting," Trevor gave her a pair of spectacles to wear. After they'd paid and left the store, Diana reluctantly allowed Candy to take her sword and shield back to Trevor's office while the two took Doctor Poison's notebook to the British War Council.
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.
