10 Most Powerful Female Justice League Members
3. Power Girl
Well, the list wasn't going to survive without a Kryptonian on it. Kara Zor-L is one of the survivors of the Pre-Crisis DC Universe. Revealed to be the cousin of the Earth 2 Superman, the fallout from the Crisis resulted in Power Girl being folded into the last surviving universe, similar to the Justice Society of America.
Fans of comics and those with a pulse will probably be familiar with Superman. Power Girl, as the biological cousin of Superman, has the same capabilities and powers. Flight, super strength, heat vision, super hearing, she has the full compliment of Kryptonian abilities. Curiously though, she has shown to be immune to certain types of Kryptonite, attributing to her origins as a hero from Earth 2.
Some of her powers have been tempered compared to the seemingly unending suite of abilities Pre-Crisis Superman had. She can hold her breath for incredibly long spans, enabling interstellar travel, but can't go on forever. She also requires sleep, something her cousin did not. However, those minor issues to not detract from the fact that Power Girl is one of the single most powerful characters in comics, female or otherwise.
