When faced with a larger threat, Diana will wear her Amazon battle armour for added protection as well as use martial weapons such as swords. Technically speaking as well, as reimagined under the George Perez 1980s reboot, the iconic costume is in fact simply the breastplate of this armour. She will also additionally use a shield for added defense when she deems it necessary.
Superhuman Strength: Diana possesses far greater strength than the finest human athletes. She kept an A.R.G.U.S aircraft from crashing by holding it up. She dispatched numerous Parademons during Darkseid's invasion and broke the Fortress of Solitude's doors down when H'el locked Superman out and took control of it. She has also managed to briefly overpower both Green Lantern and Aquaman, as well as Supergirl. She managed to defeat the goddess Artemis, as well as draw blood from The First Born.
Ares' daughter, Harmonia, chose to help Diana, however. She gave her a powerful amulet with the power to transport across dimensions. Diana slew Deimos with her razor sharp tiara, and from him acquired the other half of Harmonia's amulet. Finally, Ares stepped in to claim the talisman, but Diana bound him with her lasso of truth. He realized that to allow humans to war would leave no kingdom for him to rule. In failure, Ares declared that he would no longer trifle with the affairs of man, and also forbade his offspring from appearing on Earth. He also took the amulet and all the power which had been collected therein.
The events of Crisis on Infinite Earths greatly changed and altered the history of the DC Universe. Wonder Woman's history and origin were considerably revamped by the event. Wonder Woman was now an emissary and ambassador from Themyscira (the new name for Paradise Island) to Patriarch's World, charged with the mission of bringing peace to the outside world. Various deities and concepts from Greek mythology were blended and incorporated into Wonder Woman's stories and origin. Diana was formed out of clay of the shores of Themyscira by Hippolyta, who wished for a child; the clay figure was then brought to life by the Greek deities. The Gods then blessed and granted her unique powers and abilities – beauty from Aphrodite, strength from Demeter, wisdom from Athena, speed and flight from Hermes, Eyes of the Hunter and unity with beasts from Artemis and sisterhood with fire and the ability to discern the truth from Hestia. Due to the reboot, Diana's operating methods were made distinctive from Superman and Batman's with her willingness to use deadly force when she judges it necessary. In addition, her previous history and her marriage to Steve Trevor were erased. Trevor was introduced as a man much older than Diana who would later on marry Etta Candy. Instead, Perez created Julia and Vanessa Kapatelis, a Greek-American scholar and her teenage daughter whom Diana would live with when she was in Man's world and would be major supporting characters in the series for years.
