The Phantoms Legacy "The Legend of the Supergirl of earth 1''

When Krypton fell, Kara Zor-El was meant to protect her baby cousin Kal-El. But fate had other plans. Trapped in the Phantom Zone for years, she was finally spit out onto Earth-alone, lost, and without a purpose. Instead of a loving family, she was found by the government, who saw her not as a survivor, but as a weapon.

For thirteen years, they trained her, broke her, rebuilt her-turning her into the perfect soldier. But Kara was never meant to be controlled. She escaped, leaving nothing but destruction in her wake.

Now, years later, the world knows nothing of the woman she has become. Hidden behind the shadowy corporation Kandor Industries, Kara has built an empire, one that grants her power beyond brute strength. A ghost in the system, she is untouchable-until the Legends of Tomorrow come looking for her.

They think they're recruiting a rogue Kryptonian.

They have no idea they just stepped into the storm.
