In "Four Against Monstro," the Challengers of the Unknown face their most bizarre threat yet when a harpy steals a mysterious sarcophagus, leading them to Skull Island and a hidden lab of long-extinct creatures. Written by Bill Finger and illustrated by Bob Brown, this 1965 issue delivers a classic sci-fi twist as the team awakens in new uniforms with hourglass emblems, confronted by a council of radiation-mutated scientists. Cover by Bob Brown, the story unfolds with eerie suspense and surprising turns—without revealing how the Challs survive the island’s final explosion.
