Origin
Kara Zor-El is Superman's Kryptonian cousin, rocketed to Earth as a teenager after her home city of Argo City survived Krypton's destruction — only to face its own doom. Arriving under Earth's yellow sun, she gained the same extraordinary powers as her famous cousin and took up the mantle of Supergirl.
