Ororo was a metamutant who nearly drowned as a child, but was rescued by Queen Hippolyta of the Amazons. Hippolyta raised young Ororo as an Amazon princess beside her own daughter Diana (who as a child was very jealous of her new "sister", although the first issue of Diana's own series, Bullets and Bracelets, seemed to imply just the opposite) on the island of Themiscyra. As Ororo grew up, she displayed the ability to control the weather, and the Amazons taught her how to focus her powers into a lasso of lighting that could compel anyone bound by it to speak the truth. She eventually left her island home to enter "Man's World" as "Amazon", to use her abilities to help people.
Over the years, Amazon continued to fight for the good cause while keeping her metamutant status a secret. She eventually joined the JLX, and became their newest leader after Aqua Mariner left to stay with his Atlantean brethren. She was also present at the final battle during the Secret Crisis of the Infinity Hour.
Amazon has the metamutant power to control the weather. She can fly by creating powerful winds that lift her upwards. Her signature ability is creating a lasso out of lightning.
Training with the Amazons of Themiscyra has not only boosted her strength and speed beyond human levels, but has endowed her with amazing combat skills using both unarmed combat as well as swords.
