Federal agents King Faraday and Woodley Allen were two man of mystery... which was their job. As professionals their job was to route out foreign threats as well as local ones.
Faraday worked as a solo operative as a counter-espionage agent of the United State government. In that capacity, he eventually rubbed shoulders with Batman, Catwoman and other Gothamites of Earth-One, as well as the Teen Titans, and the Dial "H" for Hero duo of Chris King and Vicki Grant.
Allen was an agent of the United States FBI involved in unorthodox cases. To that end, he was enlisted by the boyfriend of his niece Doris into being his governmental handler. That boyfriend, Ted Knight, was he costumed crusader Starman.
