In the vast universe, there is a planet called Krypton facing collapse. As the end of the world approaches, two cousins from the 'Al' family on Krypton tacitly send their children to Earth in a spaceship. The son of Jor-El was named Kal-El, who later became Superman. The other is Jor-El's niece, named Kara Zor-El, Kal-El's cousin, and ten years older than him. Just as Krypton was about to be destroyed, the two cousins had to board a spaceship to escape to a planet called Earth. But on the way, Kara Zor-El's spaceship encountered a meteor, and just when Kara Zor-El was injured and about to die, a soul occupied her body.
