The princess of the Amazons, armed with superpowers of a god, Wonder Woman is one of Earth's most powerful defenders of peace, justice, and equality and a member of the Justice League. She is often considered an archetype for many non-comicbook heroines. She stands for Love and peace. Her original origin allegorically depicted her as a clay figure brought to life by the gods, but in recent years she has been depicted more literally as the daughter of Zeus and the Amazon queen Hippolyta.
This is a magnificent movie, well deserving all the praise heaped upon it. I am 65 years old, growing up with WWII veterans--soldiers, sailors and marines--all of them strong men in their prime, simple, humble and all of them joining the colors in 1941; men who saw horrors beyond belief ( I managed to steal a peek at the photos my dad brought home from the Pacific islands in the aftermath of a Japanese defeat--burned and mutilated corpses everywhere). As a result I spent many years studying the war in great detail. I mention all this to show that I grew up with a tremendous sense history and hope that I have some modicum of wisdom and gravitas after all these years. Along with this I became a 1st generation Trekkie in 1966, read Tolkien before it became a vast commercial success with games, comic books, and movies etc. I have always possessed a sense of wonder and fantasy.
Ares appears as a major antagonist in the live action Wonder Woman film. In Queen Hippolyta's story about Ares which she reads to Diana, Ares was condemned by the other Olympian Gods for his warmongering which led to him killing the Gods where the images show him killing Apollo, Artemis, Athena, Hades, Hestia, and Poseidon until Zeus drove him off of Mount Olympus with his thunderbolts. In his dying breath, Zeus created Themyscira for the Amazons and left them the "Godkiller" required to kill Ares should he rise again. This happens during World War I where Wonder Woman managed to slay Ares.
Wonder Woman's sexual and bondage themes in her earliest days were not without purpose, however. Her creator, William Moulton Marston, theorized that human relationships could be broken down into dominance, submission, inducement and compliance roles which were embedded into our psyche. Because males were, more often than not, dominant in societies, Marston believed that "Women as a sex, are many times better equipped to assume emotional leadership than are males."  Marston wanted to convey his progressive ideals, through his use of bondage imagery, that women are not only capable of leadership roles, but should be in charge of society. Although Marston had good intentions with these themes, in Wonder Woman's early appearances, the bondage elements were controversial, as they were often seen to overly fetishize women in power rather than promote such women. Noah Berlatsky criticized this imagery in Wonder Woman's earliest days noting that "the comics take sensual pleasure in women’s disempowerment."  Despite having the mixed messages of this imagery, Marston fiercely believed that women would soon rule the earth and meant to showcase his predictions through sexual themes in his stories. He was an open feminist while studying at Harvard where he once said "Girls are also human beings, a point often overlooked!" 
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
While Superman watched out for Zod, Diana visited the deserted Themyscira to speak to her mother, still a clay statue. In her absence, a demon from Tartarus had escaped from its prison and roamed free on the island. Wonder Woman destroyed the creature and sealed the gates to Tartarus with her lasso. Leaving the island, she received word from Batman that Superman was engaging Zod and Faora in battle. Reaching Superman’s side, Wonder Woman steadily overwhelmed Faora until Zod threatened Superman’s life. Wonder Woman was forced to let the criminals go.
