Kara Zor-El is Superman’s cousin from Argo City, which survived Krypton’s destruction intact and protected by a barrier which maintained its atmosphere. When Argo City’s inhabitants began to fall prey to the deadly Kryptonite radiation emanating from their planetoid, Kara’s parents Alura and Zor-El constructed a rocket for their teenage daughter to escape their city’s doom. Kara reunited with her cousin Kal-El on Earth and took on the mantle of Supergirl. In time Kara reunited with her parents after discovering they were still alive, having been trapped by Brainiac with other Kryptonian survivors in the bottled city of Kandor.
