Happy Birthday: Linda Danvers, Supergirl
Kara Zor-El was born and raised in Argo City on the planet Krypton. The entire city survived the planet’s destruction, separating itself and floating to safety, but most of the inhabitants were soon felled by their homeworld’s remnants, now transformed into deadly Kryptonite.
Kara’s father Zor-El sent her to Earth for her own protection, hoping she would be found and protected by her cousin Kal-El, better known as Superman. Kara landed on Earth on April 11 and her cousin welcomed her with open arms. He also helped her create a secret identity — that of orphan Linda Lee.
As Linda, she was adopted by Fred and Edna Danvers, and it was as Linda Lee Danvers that Kara attended high school and college and later began several careers. Her Kryptonian nature gave her the same powers as Superman, however, and Kara often fought crime both at his side and on her own, becoming renowned and admired as Supergirl.
Sadly, Kara sacrificed herself during the Crisis on Infinite Earths, bravely giving her own life to protect her cousin and the rest of the multiverse.
