Rastapopoulos

Roberto Rastapopoulos is the antagonist of many of the "Tintin" comic books. He is the archenemy of the title protagonist of the series. He debuted in "Cigars of the Pharaoh". According to the dénoument of its follow-up "The Blue Lotus", it is revealed that Rastapopoulos is the head of the sinister opium cartel which Tintin has been pitting his wits against in the course of two books.

In an animated film that is adapted into a similarly-titled book, "Tintin and the Lake of Sharks", he is painted as a villain directing operations from a secret underwater base. He is responsible for numerous worldwide robberies of valuable items and plans to steal a duplicating machine invented by Professor Calculus. On the other hand, in an attempt to escape by submarine, Haddock and Tintin both capture him and he is arrested by the Syldavian Police.
