Rastapopoulos subsequently resurfaced as a slave trader in The Red Sea Sharks (under the alias of the Marquis di Gorgonzola) and kidnapped the millionaire Lazslo Carreidas in Flight 714. In the latter album Hergé had him dress in a disgusting pink cowboy suit, thus transforming him from a menacing figure into a ridiculous one, an example of the way in which Hergé deliberately subverted his own fictional universe in the later Tintin books. Flight 714 ends with Rastapopoulos being abducted by an alien craft, the last that is seen of him.
Rastapopoulos also appeared in the lamentable Tintin and the Lake of Sharks, an album adapted from an animated feature of the same name, and into which Hergé had no creative input. It is not considered to be part of the Tintin canon.
Rastapopoulos first appeared in 'Tintin in America', where he is seen sitting left of Tintin, and celebrating Tintin's successful adventure in America during a Gala dinner.
