In the new drama from the world of DC Comics, Superman's cousin, Kara Zor-El, embraces her superhuman abilities and becomes the hero she was always meant to be.
On Earth, Kara acquires powers identical to Superman's and adopts the secret identity of Linda Lee, a resident of Midvale Orphanage. She conceals her blonde hair beneath a brunette wig and functions as Supergirl only in secret, at Superman's request, until she can gain, in his opinion, sufficient control of her powers. After she is adopted by Fred and Edna Danvers, Superman decides his cousin is ready to begin operating openly as Supergirl.
She attends Midvale High School as Linda Lee Danvers. In later years, after graduating from Stanhope College, she changes careers several times, holding jobs in student counseling, news reporting, and acting in a TV soap opera titled Secret Hearts. She also attends college in Chicago. Kara has many boyfriends, including Richard (Dick) Malverne, Jerro the Merboy from Atlantis, and Brainiac 5, a member of the Legion of Super-Heroes. She does, however, shun serious commitments, putting her super-career first.
Supergirl's secret identity is a closely held secret known only to Superman, her foster parents, and the Legion of Super-Heroes, of which she is as a member for a time. Like all Kryptonians, Supergirl is vulnerable to Kryptonite. Streaky, her orange cat, acquires temporary superpowers as a result of its exposure to "X-Kryptonite", a form of Kryptonite Supergirl accidentally created in an unsuccessful attempt to neutralize the effects of Green Kryptonite. Comet the Superhorse, a former centaur, is Supergirl's equine companion.
Supergirl's biological parents survive the radiation poisoning that killed everyone else in Argo City by entering the Survival Zone (a parallel continuum akin to the Phantom Zone). They are eventually rescued by Supergirl and decide to live in the bottle city of Kandor.
