Fan Casting Power Girl (2037)

Power Girl fights crime on Earth-1's sister Earth, Earth-2. It is decades behind Earth-1, and is akin to the Earth-1 1970s. She somehow and very mysteriously gets transported to Earth-1 by strange and unknown means. She meets this Earth's version of Superman, and she realizes she's indefinitely stuck there. Now, she must get used to this Earth, dealing with the culture shock and fallout of not being able to see her friends and family ever again. What she doesn't realize is a threat followed her here from Earth-1 and she has to do what she does best. Kick some major ass and look good doing it.
