Kara Zor-El is the daughter of Superman's uncle Zor-El and his wife Alura. Kara is actually older than Kal-El (Superman); she was a teenager when he was a baby. When Krypton was attacked by Brainiac, he took Kandor with him, while Kara and her parents remained in Argo. After Brainiac's attack, her father created a force-field around Argo using a Brainiac Probe. When Brainiac came to consume Argo City, her parents had no choice but to send her in a rocket headed for Earth. However, her rocket was caught in a large kryptonite-encrusted meteor and she arrived on Earth years after her cousin did.
