In this universe, Diana is one of the youngest members of the Justice League, half-sister to the Black Canary: Dinah Grant and daughter of Hippolyta Prince - The Original Wonder Woman and Ted Grant - Wildcat. Her entire life, from birth to adulthood she spent on an isolated island filled with warrior women, known as the Amazons. This island's name; Themiscyra.

After the JSA disbanded, Hippolyta fell pregnant and left to go home to Themiscyra and raise her child there. On that paradise island, Diana was trained to become an Amazon - one day taking her mother's place as their queen. One day, a traveler from the world of man known as Bruce Wayne comes onto the island without warning and is brought to meet with Hippolyta, being asked to help defend the Earth from a powerful tyrant and ruler of the planet Apokolips: Darkseid. She denies, but with permission of her mother, Diana comes along with Bruce to help save the world from becoming a hellish wasteland.
