Rastapopoulos is a fictional character in The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. He is acriminal mastermind with multiple identities and activities.
Hergé first introduced the character of Rastapopoulos in Cigars of the Pharaoh, which was serialised in Le Petit Vingtième from 8 December 1932 to 8 February 1934. Tintin runs into him at the start of the Adventure aboard the M.S. Isis, a cruise ship docking at Egypt. Here, Rastapopoulos bumps into the Egyptologist Sophocles Sarcophagus, and threatens to beat him until Tintin intervenes. He then shouts at Tintin, accusing him of being an "Impudent whipper-snapper!" Tintin recognises Rastapopoulos, commenting that he is "the millionaire film tycoon, king of Cosmos Pictures... And it's not the first time we've met..." Later in the story, Tintin runs into Rastapopoulos again, this time running into his desert film set, interrupting an apparent assault on a young woman before realizing that it was only part of the film.
