Centuries ago, an argument between Aphrodite and Ares led to the creation of the Amazons, who have been guided and protected by the goddesses ever since. Ares' recent schemes to destroy the Amazons and his fellow gods led to an Amazon champion being chosen. This champion was the Princess Diana, daughter of Queen Hippolyta, whom Hermes escorted to Man's World. There she was called Wonder Woman. Hephaestus forged Wonder Woman's golden Lasso of Truth from the girdle of the earth-goddess Gaea, and her silver bracelets which he formed from the splintered Aegis of Zeus. While the Olympian gods were her patrons, other gods were her foes. Ares and his progeny, Deimos and Phobos, quickly set about challenging the princess in her quest. Phobos created the creature Decay from the "heart of the Gorgon," which Diana quickly dispatched. Meanwhile, Deimos recruited humans on opposing sides, inciting them to war.
Wonder Woman had a minor role in Young Justice. Initially, the character was going to be excluded from the show due to legal red tape, but was included at the last minute. However, as a result of only being cleared for use late in the production cycle, she only had several speaking appearances. In the second season, she could be seen as the mentor of Wonder Girl. She was voiced by Maggie Q.
Not long after this, Athena sensed a dark destiny for the gods amidst the cosmic mechanations of Alexander Luthor Jr.. In the crisis created by his chaos, Diana was forced to kill Maxwell Lord, and incurred the ire of the world's public. The U.S. government responded by mobilizing against Themyscira, and Diana realized that as long as she was a target, the Amazons would never be safe. Diana prayed to the gods to take the Amazons to safety, but got more than she bargained for. On Olympus, she pleaded against Athena's decision to remove the gods from Earth's affairs. Regardless, the gods departed, leaving Diana bereft of family and faith.
