Sea Devils #19

This October 1964 DC thriller pits the Sea Devils against something deeply unsettling — robotic duplicates of their own teammates. Howard Purcell's cover tells the tale vividly: two hulking, blank-faced robots menace a blonde woman and a red-suited diver as flames lick the floor beneath them, while a horrified onlooker cries out that the robots contain the brains of Biff and Nicky. Looming in the background, a giant octopus adds an extra layer of aquatic dread to this book-length adventure.
