The Secret Six were a team of undercover operatives fighting crime and defending democracy, though ultimately serving the goals of a United States government group, the Agency. After many successful missions, the Secret Six retired.
Years later the original members of the Secret Six were reunited to train a new team. But tragically five of the Six - save for Carlo di Rienzi - were killed when their plane was sabotaged and crashed into a mountain. Di Rienzi established a new Secret Six and became that group's Mockingbird.
