History:
On the ill-fated planet Krypton, Zor-El was the greatest scientist in Argo City, and the creator of a weather-proof plastic dome that covered the city. When the planet exploded, Argo was hurled into space in one piece, with its atmosphere kept intact by the dome. A few years later, Zor-El’s daughter Kara was born.

When the ground beneath the city turned to deadly Anti-Kryptonite, a floor of sheet lead was laid to protect the people. However, when Kara was 15, a meteor shower struck the city. The dome was of self-sealing plastic, but the lead was punctured, releasing the Anti-Kryptonite rays and dooming the population.

Having discovered Superman’s presence on Earth, Zor-El and Alura used a small rocket to send Kara there, to be united with her cousin. Her mother made a costume for her – the first of many different outfits she would wear during her career – similar to her famous cousin’s.

Superman took her to Midvale Orphanage, where she disguised herself with a brown wig and used the name Linda Lee. At first, she was the Man of Steel’s secret weapon while he trained her to use her powers.

Superman finally decided to reveal her to the world but tragedy struck and she temporarily lost her powers due to the plots of a Kandorian villainess. During this period she was adopted by Fred and Edna Danvers. When she recovered her powers, she revealed her true identity to her adoptive parents and Superman presented her to the world.

At Midvale High, Linda befriended Lena Thorul, Luthor’s sister. Later Linda went to Stanhope University on a scholarship, and after graduation worked for a time at station KSF-TV in San Francisco. She briefly returned to college to study acting, worked for some time as a student advisor at the New Athens Experimental School in Snata Augusta, Florida, and worked for a short time in New York as an actress on the soap opera Secret Hearts. She left to go back to college, this time at Lake Shore University in Chicago.

Meantime, while still in high school, she discovered her parents had escaped destruction by entering the Survival Zone, a dimension somewhat similar to the Phantom Zone. With the help of Fred Danvers (a scientist and engineer), she freed them and they went to live in Kandor.

During the crisis on infinite earths, Supergirl and Superman were sent with other heroes on a mission to the anti-matter universe. There she destroyed the Anti-Monitor’s machines, but was herself killed, sacrificing her life to save several Earths.
