The Daring New Adventures Of Supergirl #16 featured the Maid of Might squaring off against everyone’s favorite Meta avenger: Ambush Bug.
The twist to this story was that AB thought Supergirl was literally Superman in drag. After several pages of your standard Bronze Age DC super-shenanigans, Kara sets him straight.
I always wondered if the Bug’s confusion was writer Paul Kupperberg’s way of taking a jab at DC’s Powers That Be, since the head honchos of that time considered Supergirl to be little more than a clone of her iconic cousin.
Guess the world will never know. Got to love Carmine Infantino and Bob Oksner’s gorgeous Supergirl though …
