A headstrong, and determined woman, Power Girl is a Kryptonian hero from a parallel universe who works with the Justice Society of America on Earth. Her great strength and endurance make her a powerhouse in battling crime alongside the original Green Lantern (Alan Scott), the original Flash (Jay Garrick), and Shazam.
While also working as a corporate business woman, CEO of her own company named Starrware Industries, Power Girl possesses all of a normal Kryptonian's powers under a yellow sun, including super-strength, super-speed, flight, and invulnerability. Magic and superior force can weaken her, but even these are not always enough to take this buxom bombshell out.
Born in an alternate universe known as Earth-2 from a previous Multiverse, Karen "Kara" Starr was a kryptonian survivor from that universe's Krypton who crash-landed on that universe's Earth. Taken in by Earth-2 Superman as a kind of protegee, she was introduced into that universe's Justice Society of America as "Power Girl". She was one of the few alternate universe citizens to survive the destruction of the initial Multiverse; having her history and life rewritten into the present universe's Earth.
As a kryptonian from an alternate universe, Karen possesses many of the same powers as Superman but not sharing all of his weaknesses. Still working with this universe's Justice Society of America, Karen also established a successful software development firm which she runs as CEO between her duties as a hero.
As one of the last of Earth's heroes following the war between Earth's heroes and villains, Power Girl is forced to ally with Lex Luthor to combat Brainiac's invading forces.
While eventually discovering that Luthor had killed Superman, which had led to Brainiac's arrival, she was still forced to work in his resistance due to Brainiac's greater threat. However, Power Girl and the rest of the resistance were eventually killed following a bungled attempt by Luthor to use the power rings of the Sinestro Corps to defeat Brainiac. As Brainiac had previously defeated the Green Lantern Corps and obtained their power rings, he easily defeated the small group despite the destruction of his Skull Ship.
