Doppelganger

I had to create a villain at some point. The Dark Band-Anna, or Dark Anna, is from an alternate timeline where most of Earth's life was destroyed by alien invaders. She was able to use technology from a damaged space ship to send herself to the main timeline, and decided to become a villain. Or she banished from her own world as punishment for her villainy. Or she’s an evil clone of Anna, created to destroy her. Or she’s just someone who has the same powers as Anna and decided to use them to become her evil counterpart. Her backstory is multiple choice. But one thing that is clear is that she chooses to be evil.
