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.
