Rookie cop Dan Garret is given the Vitamin 2-X formula by Dr. Franz, who intends the powerful vitamin to only be used by someone pure of heart. Vitamin 2-X gives Garret super-strength. He dons a bullet-proof blue chain mail costume and uses his powers to fight crime. He drives a hopped-up roadster and projects his beetle insignia onto walls to frighten criminals. He was later joined by a sidekick named Sparky.
