The supporting characters Hergé created for his series The Adventures of Tintin have been cited as far more developed than the central character, each imbued with a strength of character and depth of personality which has been compared with that of the characters of Charles Dickens. Hergé used the supporting characters to create a realistic world in which to set his protagonists' adventures. To further the realism and continuity, characters would recur throughout the series. It has been speculated that the occupation of Belgium and the restrictions imposed upon Hergé forced him to focus on characterisation to avoid depicting troublesome political situations. The major supporting cast was developed during this period.
Tintin's Dog who loves whisky drinking and bone chewing.
Mohammed Ben Kalish Ezab is the Emir of the fictional Arab state of Khemed, and Abdullah is his extremely spoiled, mischievous, hyperactive son. After first appearing in Land of Black Gold, the Emir and his son reappear in The Red Sea Sharks, when Mohammed Ben Kalish Ezab has been temporarily overthrown by his rival Sheikh Bab El Ehr and entrusts his son to Tintin's care. Abdullah is a serial practical joker whose favourite victim is the short-tempered Captain Haddock.
At the end of The Red Sea Sharks, father and son are presumably reunited.
