Supergirl was once considered one of humanity's greatest allies.

She helped people, protected cities, and earned the world's trust. No one imagined that it was all a lie.

Created by Russia as a weapon to conquer the planet, Supergirl spent years pretending to be humanity's friend while preparing to take control of Earth.

When her true objective was revealed, she began her attempt to conquer the planet.

The Green Lantern Corps classified Earth as a high-risk region and sent a new Green Lantern to protect it.

You.

Now, you must protect humanity while Supergirl remains on Earth, making it clear that her attempt to conquer the planet is far from over.

To millions of people, she is no longer the hero they once trusted.

Now, she is Earth's greatest threat.
