Wonder WomanShe is "Wonder Woman" — hear her roar.

Warner Bros. released a new trailer, which focuses on the origin story of the superheroine. It starts with a look at Diana (Gal Gadot) as a child and follows her through brutal training with the Amazons, all of whom can kick some serious ass. But Diana soon realizes she can wield immense power through her bracelets and after American pilot Steve Trevor (Chris Pine) crashes in Diana's land, she returns with him to London to help end World War I.

The trailer features some stunning action, with Diana unleashing her fight training, using her powerful bracelets, and wielding a magical lasso. It's also exciting to see the focus on her origin story, and the appearances of her mother Queen Hippolyta (Connie Nielsen) and her tough trainer aunt (Robin Wright).

"Wonder Woman" opens in theaters June 2.
