Power Girl

Power Girl (real name Kara Zor-L, also known as Karen Starr) is a fictional DC Comics superheroine, making her first appearance in All Star Comics #58 (January/February 1976). Power Girl is the cousin of DC's flagship hero Superman, but from an alternate universe in the fictional multiverse in which DC Comics stories are set. Originally hailing from the world of Earth-Two, first envisioned as the home of DC's wartime heroes as published in 1940s comic books, Power Girl becomes stranded on the main universe where DC stories are set, and becomes acquainted with that world's Superman and her own counterpart, Supergirl.
