Nikki Larue

A stunning “European glamor girl” who arrives in Metropolis in April 1950 with, the astounding announcement that she and Superman are engaged to be married. Lois Lane is understandably hurt and bitterly jealous until she learns that Nikki Larue is secretly “the world-famous atomic scientist” Madame Nicolai; that the U.S. government had invited her to America “to experiment with atomic energy”; and that the ruse by which she and Superman pretended to be sweethearts was designed only “to protect [her] from spies,” so that Superman “could guard [her] constantly without arousing suspicion” about the true purpose of her prolonged stay in America (Act No. 143: “The Bride of Superman!”) (TGSB).
