The last comic book I bought was Adventure #421 from the days when Supergirl was the star of that series (1972). The front cover shows the Maid of Might beset by green demons with a blonde villainess pointing a flaming sword and screaming "You've tried to destroy us. Now, Supergirl, you must die!" In the issue's story "Demon Spawn," the baddie Nightflame is in fact the evil part of Supergirl herself who lives on a microscopic world inside the Blonde Blockbuster's head. She kidnaps Supergirl and brings her to this bizarre nightmarish place which is really the heroine's subconscious, with the intention of draining her superpowers and taking her place in the outside world. In a typically sexist choice, Supergirl is only saved by the love of a good man, Geoff, the producer of the TV news show where she works in her civilian identity of Linda Danvers. Geoff, who has no superpowers, somehow infiltrates Supergirl's mind and forces Nightflame and the Demons (sounds like a rock group, doesn't it?) to retreat.
