I see London, I see France, I see Coco's underpants.
~ Jean-Claude singing after Angelica reveals Coco's underpants.

Jean-Claude is one of Coco LaBouche's assistants (the other being Kira) and the secondary antagonist from Rugrats in Paris: The Movie.

He was voiced by John Lithgow who later played Lord Farquaad.

At the beginning, he had Kira call Stu Pickles and for him to come to Paris to fix the robotic Reptar after its head ended up falling off during a test performance.

Afterwards 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 at Coco's request and locked them away to the giant garage. When the babies escape by controlling the robotic Reptar inside, 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, causing Chaz to realize who Coco really was.

In the end, he was chased off by Spike the Dog.
