Giganta

Giganta is Dr. Doris Zeul, who suffers from a fatal blood disease. She captures Wonder Woman and plans to put her "life-essence" into Wonder Woman's body using an experimental machine. Interrupted by Wonder Girl halfway through the experiment she ends up with her consciousness in a test animal gorilla named Giganta. Desperate to return her mind to a human body, Zeul the gorilla abducts a comatose circus strongwoman named Olga with size-changing abilities through unknown means (though Olga was comatose due to a mysterious shaman) and uses the machine to successfully transfer her mind into that body, keeping the villain name "Giganta".
