Jean-Claude is Coco LaBouche's assistant and the secondary antagonist from 2000 Nickelodeon animated film Rugrats in Paris: The Movie. He was voiced by John Lithgow, who would later go on to voice Lord Farquaad.
At the beginning, he had Kira call Stu Pickles and for him to come to Paris to fix the robotic Reptar. Later, he attempted to get expensive chocolate out of Angelica's mouth with his arm, but stopped after Coco made a "deal" with her. The morning before the wedding, he kidnapped Angelica and the babies and locked them away to the giant garage. When the babies start to control the robotic Reptar, he gets in a giant Robosnail and tries to battle them. But Chuckie, who is controlling the robot, fought him off as Jean-Claude fell in the seine river. He bursted into Notre Dame and told Coco LaBouche that the plan has failed. In the end, he was chased off by Spike the Dog.
