Well, Catwoman being missing for a time was true, there was more to the story, as will be revealed here!
The Catwoman's Black Magic
So, of course, Catwoman shows up, hypnotizes Lois to think she's Catwoman, and has her wait to kill him. Lois does try, but Superman and Batman take him down, and Superman finds out Lois is Catwoman, then tracks down Catwoman to free Lois. Catwoman uses her magic wand (???) to turn Superman into a black cat, and cages him in a Kryptonite cage, with Lois coming to fight Catwoman to save him.
Who will win? Tune in, same Lois-time, same Lois-channel (or, just keep reading.....).
Bad Luck For A Black Super-Cat
During the fight, Lois accidentally triggers Catwoman's Earthquake machine (sigh....) which leads Batman and Robin to her headquarters, where they capture their feline foe. But, with the magic wand out of power, how is Lois to return Superman to his natural form? Well, she gets some help from Lana Lang, who uses a magic item her archeologist father found, of course...
...the wonderfully fun camp of the Silver Age, but a first meeting between Catwoman and Lois Lane!
