With the real Superman imprisoned in the bottle city as the result of Lois Lane's having mistaken him for the impostor and having used Zak-Kulâ€™s size changing apparatus to reduce the Man of Steel to microscopic size, Zak-Kul, now clad in a spare Superman costume stolen from the Fortress of Solitude, literally usurps Supermanâ€™s life, capturing criminals and performing super-heroic deeds, basking in the real Superman's fame and glory, even going so far as to become â€œan ardent suitor of Lois Lane.â€
Believing that she is being courted by the real Superman, Lois Lane joyously accepts Zak-Kulâ€™s proposal of marriage (â€œThe answer is yes... yes... a million times yes!â€ she exclaims ecstatically; â€œHurry.. take me to the justice of the peace at super speed... before you change your mind!â€), and for a time the couple are actually husband and wife, â€œIâ€™m the happiest girl on Earth!â€ thinks Lois as she and the bogus Superman share a passionate embrace. â€œSuperman is my husband!â€
Before long, however, Zak-Kul comes to the conclusion that he will have to kill his new bride to prevent her from learning that she has wed an impostor, and Lois is rescued from seemingly certain doom only by the heroic intervention of the real Superman, who escapes from Kandor in the nick of time to save Lois, apprehend his impersonator, and return the villain to the bottle city to stand trial for his crimes.
â€œI was married to Superman for a while ... but the wrong one!â€ sighs Lois to Clark Kent soon afterward. â€œThe courts, of course, annulled the marriage! Oh, Clark, will the right Superman ever propose to me?â€
â€œEr... how would I know, Lois?â€ replies Clark slyly (Act No. 245: â€˜The Shrinking Superman!â€).
Zak-Kulâ€™s size-changing apparatus, confiscated by Superman, is now on display in the Fortress of Solitude (S No. 158, Jan 1963: â€œSuperman in Kandorâ€ pts. 1-3 â€Invasion of the Mystery Super-Men!â€; â€œThe Dynamic Duo of Kandor!â€; â€œThe City of Super-People!â€).
