The Amazons of myth reside on Paradise Island, away from Man's world. Its queen, Hippolyta once sculpted a daughter from clay. The Olympian gods took pity and breathed life into the clay and created Diana. She was raised to be a leader; intelligent, beautiful and strong.
One day, Steve Trevor, an intelligence offier for the United States Army, crashed on Paradise Island. Princess Diana took care of the ailing Trevor and nursed back to health with the Amazon's Purple Ray. Queen Hippolyta decided this was a sign that the Amazons should join in the fight against Hitler and the Nazis. A tournament was held to decide which Amazon would go.
Though she was forbidden to participate, Diana secretly participated with a mask and won. After revealing her identity, Hippolyta relented and allowed her to escort Trevor back to civilization as Wonder Woman. Once back, she took on a secret identity as Diana Prince and worked in the United States War Department alongside Trevor. Armed with bulletproof bracelets, the magical Lasso of Truth and Amazonian training, Wonder Woman soon established herself and even joined the Justice Society of America.
Following the 1951 hearings, Wonder Woman decided to sign a loyalty oath and helped carry out covert operations on the US' behalf. She was sent to Cambodia to secretly retrieve a crashed C-47 transport. While passing through Laos, she encountered a rebel base with women locked in tiger cages. Wonder Woman returned in the evening, disarmed the men and let the women decide what to do. When she failed to report to Washington, Superman was dispatched to investigate. To his shock he found all of the men slain.
She was ultimately forced out for enforcing her beliefs and returned to Paradise Island. The Island happened to be in the path of the Centre as it headed towards America's eastern seaboard. Wonder Woman was heavily wounded but managed to fly her trademark Invisible Plane to Florida and issue warning. She came to and joined the final battle. Afterwards, she helped found the Justice League of America.
