Challengers of the Unknown #87

A sense of desperate urgency drives this 1978 DC issue, as a mysterious white-faced figure in red urges the team to flee into a circular Time-Sphere while a menacing green creature looms at their backs. Below, three Challengers in their familiar red-and-yellow uniforms fire weapons and scramble for safety, the cover teaser asking whether these "death-cheaters" have finally met their match. With cover art by Alex Saviuk and Dick Giordano and an interior story titled "Twelve Million Years to Twilight" by Carla and Gerry Conway with art by Keith Giffen, this issue delivers the kind of high-stakes adventure that made the Challengers of the Unknown such a compelling corner of the DC universe.
