Wonder Woman's origin story relates that she was sculpted from clay by her mother Queen Hippolyta and was given a life to live as an Amazon, along with superhuman powers as gifts by the Greek gods. In recent years, DC changed her background with the retcon that she is the daughter of Zeus and Hippolyta, jointly raised by her mother and her aunts Antiope and Menalippe. The character has changed in depiction over the decades, including briefly losing her powers entirely in the late 1960s; by the 1980s, artist George Perez gave her an atheltic look and emphasized her Amazonian heritage. She possesses an arsenal of advanced technology, including the Lasso of Truth, a pair of indestructible bracelets, a tiara which serves as a projectile, and, in older stories, a range of devices based on Amazon technology.
The American theme of Diana's costume was explained by Pérez in the Challenge of the Gods storyline in which Diana engaged in a series of trials arranged by Zeus as punishment for refusing his advances. Diana met the spirit of Steve Trevor's mother, Diana Trevor, who was clad in armor identical to her own. Trevor revealed that during World War II she had crashed on Themyscira while on duty as a U.S. Army pilot. She blundered into an Amazon battle against Cottus, a multi-armed demon, at the portal to the underworld. Trevor was drawn into the battle, although she was armed only with her side arm. She wounded the beast before suffering a mortal blow, allowing the Amazons to reseal the portal.
While Diana stood admiring the replica, Bruce Wayne appeared. He proceeds to angrily confront her by grabbing Diana's arm and asking her about the information device that she had stolen. Bruce claims to see right through her "babe in the woods" act, saying that while Diana doesn't know him, he's met "a few women like [her]". Diana, however, calmly smiles and retorts that Bruce has never met any women like her. She then proceeds to tell Bruce that she was unable to obtain anything from Bruce's device, due to Lex Luthor's data having military-grade encryption. Diana explains her intention to re-obtain her photograph from Luthor, stating that she only borrowed Bruce's device, and has already returned it to him shortly beforehand (placing it into the glove compartment of his car), before calmly excusing herself and leaving.
In order to prove her devotion to her people, the Amazons issued a challenge to Diana, one she would have to meet in two days. In the meantime, the Justice League had tracked the insectoid queen down to a remote mountain. The League journeyed deep into the mountain and encountered the queen. Diana condemned her for the lives she has taken, but the insectoid queen replied that it was Diana’s actions, namely her throwing of the First Born into the depths of the Earth, that awoke the insectoids from their slumber.
During the Silver Age, under writer Robert Kanigher, Wonder Woman's origin was revamped, along with other characters'. The new origin story increased the character's Hellenic and mythological roots: receiving the blessing of each deity in her crib, Diana is destined to become as "beautiful as Aphrodite, wise as Athena, strong as Hercules, and swift as Hermes."
Chris Pine was cast as Steve Trevor, a character he described as a "rogue-ish, cynical realist who's seen the awful brutish nature of modern civilization" and added that he is a "worldly guy, a charming guy". He signed a multi-picture deal. Lucy Davis' performance as Etta Candy is the first live-action cinematic portrayal of the character. As well, Elena Anaya's performance as Doctor Poison is the cinematic debut of that character. Nicole Kidman was in negotiations for the role of Queen Hippolyta, but was forced to drop out due to scheduling conflicts with Big Little Lies.
