Explorers of the Unknown #5

Two confident young women dominate this cover — one in a swimsuit brandishing a rifle, the other in a colorful wetsuit with dive fins and scuba gear perched on a sleek amphibious vehicle — as they cheekily invite their teammates to "take the plunge." Archie peeks in from the upper corner, clearly not quite sure what he's gotten himself into, while the bold tagline "Terror Beneath the Waves!" promises aquatic adventure ahead. Rex W. Lindsey's cover art gives this 1991 Archie series entry a fun, action-packed energy that blends spy-thriller flair with the gang's trademark lightheartedness.
