Wander Woman's story begins at her home Krypt, when it's core goes nuclear and destroys its self, only one city survives due to a special protective dome.
Like the rest of the planet’s debris, the ground beneath Argon City had turned into radioactive kryptonite and so lead shielding is put in place.
Wander Woman, daughter of Zor-E and Alura In, grew up knowing that her older cousin Wander Man is living as a hero on Earth. When Wander Woman turned 15 years old, a meteor shower ruptures Argon City’s dome and its protective lead shielding fails. Her parents send her to her cousin, so that he, along with the super-powers Kryptyians gain from suns like the one Earth orbits, will keep her safe.
