History:Kara Zor-El was born in Argo City, a domed settlement on Krypton that survived the planet’s destruction due to its protective force field. However, Argo City was ultimately doomed when a radiation crisis made it uninhabitable. Before its final collapse, Kara’s parents, Zor-El and Alura, sent her to Earth in a rocket, just as Jor-El had done with her cousin, Kal-El.Arriving on Earth as a teenager, Kara was discovered by Superman, who revealed their shared Kryptonian heritage. Unlike him, she had grown up knowing her origins. Superman helped her adjust to life on Earth, creating the secret identity of Linda Lee and placing her in Midvale Orphanage. Eventually, she was adopted by Fred and Edna Danvers, taking the full name Linda Lee Danvers.Initially, Superman instructed her to keep her existence secret until she mastered her powers. Over time, she trained in the use of her superhuman abilities, assisting Superman in his adventures and operating independently as Supergirl. She became a beloved protector of Earth, eventually joining the Legion of Super-Heroes, a group of young heroes from the 30th century.As Supergirl, she balanced her civilian life with her heroic responsibilities, forming friendships with fellow heroes and battling threats such as Lex Luthor, Brainiac, and various intergalactic foes.
