Supergirl

The original and most well known Supergirl is Kara Zor-El, who was created to be a female counterpart to Superman. Supergirl made her first appearance in Action Comics #252 (May 1959) and was created by Otto Binder and Al Plastino. 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 - and the wisdom to properly use them. After she is adopted by Fred and Edna Danvers, Superman decides his cousin is ready to begin operating openly as Supergirl. Her debut was delayed by her powers being stolen by a Kandorian villainess; and during this period, the Danvers family adopted her.
