15 Actresses Perfect for the Role of Power Girl in the DCU

Power Girl—Kara Zor-L, often operating publicly as Karen Starr—is presented across DC continuity as the Earth-Two counterpart to Supergirl, a Kryptonian with abilities comparable to Superman. The character debuted in ‘All-Star Comics’ #58 and has longstanding ties to the Justice Society of America, with creator credits that include Gerry Conway, Ric Estrada, and Wally Wood; across later runs she has also been written by figures such as Paul Levitz and Geoff Johns in stories that emphasize her multiversal origins, Kryptonian heritage, and team leadership.

Adaptations commonly highlight her role as a frontline JSA member, her corporate-leader alter ego in tech and science fields, and her connections to other Kryptonians through cross-Earth storylines.
