Kara Zor-El (Earth-1543)

History
"Some of us try hard to make the world a better place than it was when we found it. I know that's what I try to do. I won't always be successful. But that's life. I'm Power Girl. This is my life ... and y'know what? I'm pretty happy with it. (For now at least.)"

Surviving Krypton
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.

After some initial confusion, Kara was found by Superman and trained by Wonder Woman. She was captured by Darkseid, and after being brainwashed, attacked her own cousin. Superman defeated her and returned her to Earth, where he faked her death so Darkseid would not come looking for her.
