Jacques is the hidden tertiary antagonist of Scooby-Doo on Zombie Island. He is the only male to become a were-cat.

He was voiced by Jim Cummings, who also voiced Cortes, NegaDuck, and Steele.

Originally represented as a genuinely friendly Cajun ferry driver, it was revealed that he tricked the gang into going to Moonscar Island.

As Scooby and Shaggy were running from the zombies, it was revealed that Jacques was also a were-cat. It was also revealed that he was aware that Simone Lenoir and her aid Lena Dupree were draining the life sources of the former inhabitants of the island in order to preserve their immortality. He later asked for immortality, and they granted him it. That meant that unlike Simone and Lena, who did not know that the cat god would curse them to drain life from others, Jacques had absolutely no problem with having to kill others to preserve his immortality. Therefore, this makes him one of the most despicable antagonists to ever appear on Scooby-Doo.
