The Black Island
In the issue "Flight 714" of The Adventures of Tintin, Professor Calculus states that he used to be proficient in savate in his younger years. However, when attempting a kick, he ends up falling terribly, prompting stunned reactions from the onlookers. Dazed, Calculus remarks that he is out of practice. In "The Black Island", Tintin himself kicks a villain and calls it a savate move.
