Universe/Timeline:
Marvel Universe
Known as the G-Men in the 1950's, this team of heroes operated through their FBI liaison Jimmy Woo before disbanding at the request of President Eisenhower. In the modern age, the surviving members reformed and took over the criminal organization known as Atlas, making it into a force for good.
Jimmy Woo later authorized Amadeus Cho to make his own Agents of Atlas roster, an international roster of heroes from Asia and the Pacific Rim.
