Kara Zor-El escaped Krypton and gained astounding abilities under Earth-2's yellow sun. Adopted by Clark Kent and Lois Lane, she was coached by Superman (her cousin, Kal-El) and yearned to become a Super Hero. When Superman, Batman, and Wonder Woman died after Earth-2 was invaded by Apokolips, Kara and her friend Robin were ejected from their universe. On Prime Earth, Kara rebranded herself as technology entrepreneur Karen Starr, building a company dedicated to bridging dimensions. As Power Girl, she covertly secured funds and confiscated useful technologies in a bid to return to Earth-2.
