The villainous Blue Snowman terrorized a small southern farming valley with a small army of robot doubles and "Blue Snow", a strange type of snow that instantly froze everything it touched - including people. Worse, blue snow could not be melted, except with a chemical compound that only the Blue Snowman knew.
Wonder Woman defeated the Blue Snowman, and revealed that the "Snowman" was actually a local woman, using a male disguise to throw off suspicion. Her scientist father had died creating blue snow, and she used the invention for her own gain.
