|~ Jacques in his monstrous werecat form, as he stops Scooby and Shaggy in their path.|
Jacques is a supporting antagonist in Scooby-Doo on Zombie Island. He is the only male to become a werecat.
Jacques was originally represented as a genuinely friendly Cajun ferry driver, but it was later revealed that along with Lena and Simone, 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 force of the former inhabitants of the island, in order to preserve their immortality. He later asked for immortality, and they granted it to him. 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.
- Jacques, alongside The Evil Entity, are the only Scooby-Doo villains to be labeled as Pure Evil.
