Joseph Chill was an American geneticist working for the United States government in an attempt to create their own superhuman being. In the 1970s, Chill's sponsor Nightwing chose a South Carolina town and drugged its inhabitants with his drug, the Miraclo Solution, to create an army of super-beings. However, the results left the residents either dying from the experiment or transformed into heavily deformed mutants with the exception of a surviving and normal appearing infant named Harvey Dent. Chill's experiment was considered a failure to the eyes of his superiors and Chill soon thereafter went into obscurity. Unknown to Chill or his superiors, Chill's experiment would proved to be a success decades later when an adult Harvey Dent manifested his powers and became known as the Superman.
