Joh Fredersen

Joh Fredersen (pronunciation: "yoh"), lesser known as Johan Fredersen, is one of four inhabitants of the All-Seeing Eye, as the only interchangeable inhabitant as he also controls the Technodome, and is also referred to largely as the Master of the City. Fredersen is singlehandedly one of the most intimidating audiences to ask for in the City Under the Sea. Despite the fact he is rarely seen, he has a hand in controlling most of the decisions which pass through the All-Seeing Eye.

He makes his debut in the episode of the first part of the series, "The Mind is a Beautiful Machine".

Joh Fredersen is a character owned by the author, Thea von Harbou, and the director, Fritz Lang.
