Francois has fair skin and long, brown hair. He has a goatee and a pencil moustache. He wears circular glasses with purple lenses at almost all times, and his standard outfit consists of a red-and-white shirt, a blue beret, blue jeans and brown loafers.
Francois is a very conceited character, and will do anything for attention. The possibility of fame and fortune is often what motivates him to help Cap'n Turbot, whether he must take a photo to be featured in a magazine or find the bones of a dinosaur skeleton in hopes of being named the "paleontologist of the year." He speaks with a French accent and often replaces words with their equivalent in French (for example, "bleu cheese" instead of "blue cheese"). Cap'n Turbot mentions that Francois had lived in France before moving to Adventure Bay. Francois is also a skilled athlete and can play both volleyball and soccer.
- Cap'n Turbot - Francois often acts as a sidekick-like figure to Cap'n Turbot. He is almost always seen alongside his cousin, despite how the two argue about many things. Francois tends to put his needs before the captain's, and is the only resident of Adventure Bay who calls his cousin by his first name, Horatio.
- The PAW Patrol - Francois is a good friend of the PAW Patrol pups and Ryder. They rescue Francois and Cap'n Turbot on a regular basis. Skye is particularly fond of him and says, "Poor Francois!" whenever he is in danger.
- Mayor Goodway - Francois and Mayor Goodway interact occasionally. In "Pups Save a Big Bone," Cap'n Turbot introduces the mayor to Francois, who nervously laughs in her presence. In "Pups Save a Tightrope Walker," Mayor Goodway invites the town to watch Francois walk a tightrope between the bridge and the Lookout. She says to the townspeople, "Francois puts the adventure in Adventure Bay!"
- Francois' camera is blue and red in most episodes. However, it is yellow in "Pups Save the Turbots" and partly orange in "Pups Save the Diving Bell."
