Mohammed Ben Kalish Ezab is the Emir of the fictional Arab State of Khemed. His only son and heir is Abdullah, the mischevious Crown Prince. Just like his Son and Professor Calculus, he gets extremely angry if he is called a Goat.
Although Generally Kind-Hearted, Ezab flies into a Characteristic Rage if he feels insulted, ridiculed or humiliated. He is especially provoked and Loud Mouthed if he ever hears Captain Haddock (or anyone else) call him a "Goat", "Fat Face" or "Fat Head". He also gets very Mad if Muller (or anybody else) stuffs a Hat down his nose.
