 History:Kara Zor-El was born in Argo City, a Kryptonian settlement that survived the destruction of Krypton by existing in an alternate dimension known as the "Inner Space." Raised by her parents, Zor-El and Alura, Kara grew up in a peaceful, scientifically advanced society.One day, the Omegahedron, a powerful energy source that sustained Argo City, was accidentally lost in space due to Kara’s curiosity. Without it, Argo City faced destruction. Determined to recover the Omegahedron and save her home, Kara used an experimental space pod to travel to Earth.On Earth, Kara discovered that she possessed extraordinary abilities under the yellow sun, similar to her cousin Superman. She assumed the identity of “Linda Lee” and enrolled in the Midvale School for Girls while secretly searching for the Omegahedron.However, the Omegahedron had fallen into the hands of Selena, a power-hungry sorceress who sought to use it to dominate the world. As Supergirl, Kara battled Selena’s dark magic, enduring numerous obstacles, including an encounter with the Phantom Zone, where Selena temporarily trapped her. Despite these challenges, Supergirl ultimately defeated Selena, reclaimed the Omegahedron, and restored power to Argo City.Having fulfilled her mission, Kara chose to return to Argo City rather than remain on Earth.
