The Dictionary was an enemy of Vigilante.
A member of the Rainbow Man's gang. Billy Deegan was given the nickname "Dictionary" because of his tendency to use big words in his speech. He was much more intelligent than his fellow henchmen. Ultimately, his intellectual superiority and large vocabulary didn't help him against the crime-fighting Vigilante, who defeated him and his boss countless times.
