Believed to be the granddaughter of the ancient Atlantean Mage Arion, Kara was sent thousands of years into the future to spare her from Arion's evil half-brother, Garn Daanuth. Kara emerged from her time-spanning life-pod and was taken under the wing of Superman, who introduced her to the Justice Society of America, a team that helped Kara to master her own magically-created superpowers and adopt the guise of the heroine Power Girl.
