Earth

Earth is a planet that orbits a yellow sun.

History
Right before Krypton exploded, Kara Zor-El was sent to Earth along with her cousin, Kal-El, to watch over him. However, she was knocked off course. He arrived, and grew to become a world-famous superhero, Superman. Kara only arrived later, having been caught in the timeless Phantom Zone. She adopted the Earth as her home, eventually becoming a superhero in her own right, Supergirl.

Unfortunately, while Kara was in the Phantom Zone, her pod passed next to a kryptonian maximum-security prison called Fort Rozz that followed her to the Earth. Shortly after Kara got there, Fort Rozz crashed in the planet, releasing dozens of dangerous convicts.
