Princess Diana of Themyscira is an Amazonian warrior princess and one of the world's first superheroes, known as Wonder Woman. She is the daughter of Queen Hippolyta and Zeus, king of the Olympians. Born on Themyscira, Diana was raised in paradise, hearing tales of her the Amazons' great task of defeating the God of War, Ares, and bringing peace to the world, ushering in a new era of peace to the world. Upon coming of age, Diana began pursuing the life of a warrior, despite her mother's rejections. Determined to serve, she ultimately enticed her aunt Antiope to train her in secret, but was soon discovered by her mother, Queen Hippolyta. Begrudgingly, the queen accepted Diana as a warrior, and ordered Antiope to train her better than any other Amazon.
Pérez and Potter wrote Wonder Woman as a feminist character, and Pérez's research into Greek mythology provided Wonder Woman's world with depth and verisimilitude missing from her previous incarnation. The incorporation of Greek gods and sharply characterized villains added a richness to Wonder Woman's Amazon heritage and set her apart from other DC heroes.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
