Challengers of the Unknown #72

Neal Adams delivers a genuinely unsettling cover for this 1970 DC adventure, centering on a wide-eyed, terrified woman clutching a black cat that lunges toward the viewer with claws extended — the creature radiating an eerie yellow glow that suggests something far beyond an ordinary feline. Two Challengers in their distinctive purple-and-yellow uniforms rush in from behind, one urgently warning that the cat's scratch can destroy, while the bold tagline "A Plague of Darkness!" sets the ominous tone. With a story by Denny O'Neil and interior art by Dick Dillin and Frank Giacoia, this issue promises the kind of supernatural suspense the Challengers of the Unknown did so well in their prime.
