Koenig was an SS officer who along with two soldiers landed on the English coast in 1941 to retrieve a piece of Chronosteel. They intended to use it as the main componant of a device that would block out British radio signals, allowing German ships to attack without being detected. They set up headquarters in a local church and were assisted by Nazi spy Ms. Wyckham. George Woods and Clyde Langer rang the church bell and alerted the Home Guard, who quickly arrested Koenig and his men.
- Although referred to as a lieutenant, he actually has the insignia of an SS hauptsturmführer (captain) in an apparent costuming error.
