Power Girl Sketch

As a Kryptonian of the Earth-Two universe, Power Girl has all the powers of Pre-Crisis Superman. She has super strength, speed, flight and invulnerability. She also has super senses and heat vision. When Supergirl of Earth-One arrived, the two's power seemed to go haywire when they touched each other. They battled briefly and appear to be evenly matched. Power Girl also has the same weakness as Superman except hers is an occasional weakness to Kryptonite. The reason it is occasional weakness is because she is from Earth-Two. It was revealed in Infinite Crisis that she and other Earth-Two Kryptonians could only be affected by Kryptonite from Earth-Two and not Earth-One. In the Justice League Unlimited cartoon, Galatea is actually a clone from Supergirl. She was created by Professor Hamilton and Project Cadmus. She was designed to defeat Supergirl and Superman if they were to go rogue and destroy Earth.
Even though Galatea was cloned from Supergirl, her mental state and age appearance make them different. Galatea is portrayed in Justice League Unlimited as Galatea but is really supposed to be Power Girl who is Supergirl in a parallel universe known as Earth-Two. Even her costume is more inspired by Power Girl's than Supergirls. Well, as always, ENJOY
