Born to Hippolyta, Queen of the Amazons, Diana lived a serene and joyful life until the intervention of Steve Trevor upon the island of Themyscira. A tournament was held among the Amazons to determine the representative that would return to Man's World along with Trevor. Diana defeated the other Amazons but was tasked with the final challenge, deflecting a bullet fired from a gun by her mother. After winning the contest Diana was awarded a suit of armor and the Lasso of Truth and left for the United States, though upon her arrival she was arrested and detained in a cell. Falling into despair, Diana was visited by the Gods of Olympus in their animal forms: a peacock, deer, owl, mouse, eagle, dove and tortoise, who granted her the gifts of strength, speed, endurance, empathy and flight.
When she has matured into an adult, Menalippe, the Oracle of the Amazons sees a vision in which the Gods and humanity is in danger from Ares. Soon they are approached by the Gods and tasked with organizing a tournament in order to chose a champion, who will save them from impending Doom. Diana competes against her mother's wish and win. Athena then sends her a weapon, the Lasso of Truth forged by Hephaestus from the girdle of Gaea.
On November 3, 2016, Rupert Gregson-Williams was hired to write and compose the film's music. He was joined by Evan Jolly, Tom Howe, Paul Mounsey, and Andrew Kawczynski, who provided additional music. The soundtrack was released on CD, digital, and vinyl the same day as the film. Australian musician Sia sang a song for the film, titled "To Be Human", featuring English musician Labrinth. Written by Florence Welch and Rick Nowels, the track is also featured on the soundtrack. The soundtrack also features samples from Wonder Woman's theme "Is She with You" from the Batman v Superman: Dawn of Justice soundtrack composed by Hans Zimmer and Junkie XL.
Wonder Woman did not keep her identity a secret, and initially did not consider herself a superheroine. Indeed, her character was wide-eyed and naive, innocent and without guile. Diana spoke only Themyscirian, a variation of ancient Greek, and had to learn English when she arrived in the United States. Fortunately, Diana soon met Julia Kapatelis, a scholar in Greek culture, and her daughter Vanessa Kapatelis who helped the Amazon princess adjust to the world of men. However, for all her apparent naiveté, Diana was a trained warrior, and had no compunction against using deadly force when called for. For example, she felled the god Deimos in battle and felt completely justified under the circumstances. Through Pérez's tenure on the book, Diana confronted war, injustice, inequality, death and conflicts involving the Olympian Gods.
Wonder Woman managed to stabilize the plane when it was hit by the shockwave. Hermes and Artemis also arrived at Olympus, where Artemis discovered that Apollo had died in the attack. Among the ruins of the tower, the First Born claimed the throne of Olympus. Wonder Woman confronted the First Born, but he gained the upper hand. However, Hera arrived at Olympus, having regained her Olympian powers, revealing that Apollo had restored them before dying. Hera teleported Wonder Woman and her allies to Paradise Island. There, Wonder Woman found Zola, safe. Hera had also restored the Amazons back to life. Wonder Woman chose to lead them to battle as the new God of War.
By the time that Robert Kanigher took over the character, a change away from traditional comics as a whole was accomplished. He eventually veered completely away from superheroism and essentially only told stories involving the Wonder Family, which consisted of Wonder Woman, her teenage version Wonder Girl, her baby version Wonder Tot and her mother. This eventually proved not very popular and Kanigher was forced to rethink the character and cast her in a more traditional superhero context (he actually explained this decision in comics to the reader with his various creations vying to remain in continuity against his wishes). It was at this time for instance that Wonder Woman saw the return of some characters that had been missing for some time such as the Cheetah or Doctor Psycho. It was also at this time that she became a founding member of the original Justice League of America.
"Gas was intended to win the war. On that much Wonder Woman is absolutely right." said David Hambling in Popular Mechanics. Rachel Becker of The Verge stated that despite the scientific liberties of using a "hydrogen-based" chemical weapon as a plot device, the film succeeds in evoking real and horrifying history. "First off, mustard gas is such a horrible, terrifying weapon, it doesn't need to be made more potent. But if you were a chemist bent on raining destruction on the Allied forces, you wouldn't do it by replacing the sulfur atom in mustard gas with a hydrogen atom. You'd know that sulfur is the linchpin holding together this poisonous molecule."
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
