Jacques was the French/Cajun ferry driver to Moonscar Island. He brought visitors to the island so he, Lena Dupree and Simone Lenoir could drain their life in order to maintain their immortality, which included werecat transformations.
He was a chubby, white-haired man with a kindly expression.
As a werecat, he was tall, very muscular, and grew brown fur all over his body. He retained his moustache which was the same colour as his fur.
He was kind to the gang upon meeting them and chatted with them on the ferry ride. He used several Cajun/French expressions in conversation.
According to Simone, Jacques had desired immortality and willingly served Simone by ferrying potential victims to the island, showing he didn't care about the lives he destroyed to preserve his immortality. He also showed a sadistic streak when he threatened Shaggy and Scooby, snarling, "Whatsa matter- cat got your tongue?" and immediately began chasing them, after Shaggy Rogers and Scooby-Doo came to him for shelter from the zombies.
Powers and abilities
In human form, Jacques possessed no outward physical or magical abilities outside of a normal human.
In cat form, however, Jacques obtained a much more defined and bulky physique. He was "granted" cat creature abilities and identical powers by Lena and Simone. Unlike Lena and Simone, he did not use voodoo dolls, as he could run very fast and was very strong (he lifted Scooby and Shaggy at the same time, for example).
Scooby-Doo On Zombie Island
It was unknown when or precisely how, but at some point in his life, Jacques would be "granted" immortality by Simone and Lena in exchange for his service as a ferryman to bring potential victims to the island without suspicion. This likely occurred after middle age, as cat creatures appear at the age when they were granted the powers (Lena and Simone look the same as they did in the 200-year-old flashback, for example).
He would meet the gang who, as Lena explained, were looking for a genuine haunted house. He replied, "If they want haunted, they come to the right place!"
He dropped them all off at Moonscar Island and left to await the night of the Harvest Moon. When the night came, he docked at the island and was met by Shaggy and Scooby, who felt relieved to see him until Jacques assumed his werecat form and chased them. At one point he caught them and mockingly growled, "Whatsa matter - Cat got your tongue?" Zombies jumped onto Jacques, allowing the boys to escape. After stumbling upon the ritual chamber, Jacques reappears and is seconds from draining Shaggy; Scooby saves him by squirting pepper juice in Jacques' eye.
The three cat creatures had the gang cornered when they suddenly disintegrated when the life-draining ritual failed to be completed in time.
