By 1934, Tintin, the comic creation of Belgian cartoonist Herge, had visited the Soviet Union, the Congo, and the United States. The intrepid young reporter had outsmarted bolsheviks, diamond smugglers, and gangsters. But every Sherlock needs his Moriarty, every d'Artagnan needs his Richelieu. So in the fourth volume, Herge sent Tintin to Egypt and created Rastapopolous, "the genius of evil".
Oh, sure, the name screamed Greek (and the infrequently-used first name, Roberto, screamed Italian or Spanish), but Rastapopoulos was a movie studio head (oh-oh) who turned out to be a grand master of an occult organization... (No? Right? No?)
No. Well, maybe, yes. Apparently, there were a lot of antisemitic tropes in Rastapopoulos' behavior that Herge eventually got away from. (And, if you are not comfortable with ethnic stereotypes, do not, we beg you, do not look at his depictions of natives in the Congo story!) Herge insisted that Rastapopoulos was not a Jewish stereotype... but a Greek one, as he began to resemble shipping tycoon and eventual Mr. Jackie Kennedy, Aristotle Onassis.
Of course, being Greek does not preclude one from being a Jew, but Rastapopoulos owned an airplane company named "Arabair". So we're sticking with "No".
Not that making your arch-villain a stereotype of ANY ethnicity is much better...
