Atlee hailed from a race that lived deep below the planet’s surface. Her culture was intrinsically tied to the sanctity of Earth, and her kind occasionally took measures to make sure that the ecosystem was protected. To this end, she was given geokinetic powers based upon the genetic template of her predecessor. Taking human form, she rose to the surface and began adventuring as a hero. Adopting the name Terra, she was determined to help anyone in need.
