Biography
Originally represented as a genuinely friendly Cajun ferry driver. It was later revealed that he had 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 werecat. It was also revealed that he was aware that Simone Lenoir and her aid Lena Dupree were draining the life sources of the former inhabinants of the island, in order to preserve their immortality. He later asked for immortality, and they granted him it. 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.

He was defeated, when the moon's shadow past the alignment of the Harvest Moon. He, along with the other werecats disintegrated, and turned to ashes.
