Stormy Foster was a pharmacy assistant clerk who worked at Vaughan's Cut Rate Drugs, a pharmacy located in the city somewhere in California. The pharmacy was run by the elderly Dr. Vaughan. Stormy was his meek but loyal right-hand man until he discovered a vitamin that when ingested would give superhuman strength. He used this vitamin to become the superhero known as the Great Defender. He was occasionally assisted by Ah Choo, a horribly stereotypical Chinese-American boy who worked for the nearby drugstore.
