Superwoman (Lois Lane)
In the first reference to a Superwoman (Act No. 60, May 1943) Lois Lane got into an argument with Clark Kent, walked angrily into the street, and was struck by an oncoming truck. Clark took her to the hospital, where she received a blood transfusion from Superman. When she awoke a short time later, she found that she had amazing powers, accidentally smashing her typewriter at the Daily Planet and finding herself able to leap great distances. However, since she apparently lacked the acting skills of Clark, she was instantly recognized as Lois Lane. The entire incident was apparently a dream or hallucination; Lois woke up in the hospital after undergoing a brain operation.
In another story, (S No. 45, Mar/Apr 1947) Superman encountered the faux-magicians Hocus (spelled in one frame as Hokus) and Pocus (see Hocus and Pocus, whom he had tricked into believing they had magical powers. After they "turned" Clark Kent into Superman to save Lois Lane's life, he was forced to play along and continue the deception. The two magicians subsequently "turned" Lois Lane into Superwoman, and Superman followed her around making her believe that she had actual superpowers. After she realized that she didn't know her own strength and wouldn't be able to live a normal life (a realization engineered by Superman) she convinced Hocus and Pocus to make her normal again.
In another story, (Act No. 156, May 1951: "The Girl of Steel") Lois gets super-powers temporarily by a vivanium machine made by Lex Luthor. She notices her powers when she rips off a steel door and holds backs a street-car. She converts herself to Superwoman (with blonde hair) and meets Superman when a new press' flywheel goes haywire. As Superwoman she has trouble managing her strength, crashes a bank sign, has trouble getting a getaway car and avoiding a crash with a trolley. Later, she was manipulated by Lex Luthor to build a better vivanium machine, and when Superman catches Luthor, she loses her powers.
Lois Lane's imperfect Bizarro clone also got a shot at being superpowerful. As Stupor-Woman (Adv No. 288, Sep 1961) she was granted powers by Bizarro-Mxyzptlk, who was imprisoned for breaking the Bizarro Code.
