Cheese Shogun Roquefort is the ruler of the "Cheese Empire" made up of stereotypical Japanese warriors made out of cheese.
He takes great offense at the idea of cheese being eaten since he considers it more valuable than gold.
He appears in Operation: T.H.E.-S.H.O.G.U.N., stealing all the cheese from a new cheese-centric restaurant.
He kidnapped a large group of innocent civilians, among them Numbuhs 2 and 4, who attended the opening of the restaurant, and forced them to work in his Cheese Mines. After escaping, Numbuh 4 freed the workers and led them to an exit while Numbuh 2 battled the Shogun in his throne room.
Roquefort was eventually defeated when he accidentally hit his head on the ceiling of his throne room during the battle, knocking himself out.
He was not seen again until Operation: I.N.T.E.R.V.I.E.W.S., where he is among the numerous characters competing for the Delightful Children From Down The Lane's birthday cake. He and his ninjas however give up when they learn that the cake is not cheesecake (which is made from cream cheese).
- The Cheese Shogun is one of few villains not based on something children dislike, but is a standard Theme villain.
- He's one of the few characters (if not the only one) to find Numbuh 2's jokes/puns funny.
