In his first episode, Courage believes that Jean is a man-eater who cooks his customers into burgers. As another customer seems to have disappeared after going to use the restroom, Courage hears a suspicious sounding conversation between Jean and his wife. It makes him fear he and Eustace are next on their menu. Being chased by Jean, who wants Courage and Eustace to meet his wife, the dog finally manages to escape home, leaving Eustace behind. At the end, however, it's revealed that Jean and his wife were just making sculptures made of beef and using their customers as an artistic muse. The customer who seemed to have been eaten was actually watching them making a sculpture of himself, which he even offered to buy. Eustace was also served a sculpture of himself, which he gladly ate.
Jean Bon is never portrayed as a villain, even though Courage is very suspicious of him in his first appearance, believing that Jean eats his customers. He can come across as a odd as he stared strangely at Courage and by occasionally speaking in an ominous tone of voice, but he is an enthusiastic, friendly person who enjoys his (innocent) profession very much. He runs his diner with his wife, a fellow sculptor of meat, whom he adores dearly. He's very generous to his customers, sometimes providing second helpings on the house, selling children items free of charge, and even making meat sculptures of his favorite customers. He claims to have the best, cheapest and juiciest burgers in Nowhere.

- Apparently Jean Bon runs and possibly owns two stores: a butcher department at Dil's General Store and his famous fast food joint.
- His name is a pun on the French word "jambon," which means "ham." However, he reveals in his first appearance that he is not actually French and just uses the name because he likes the sound of it.
- Even though Jean Bon is built to be a villain in his first appearance it's actually Courage's own paranoia that serves to torment Courage. Jean Bon is never a true antagonist on the show.
