Episodes have been drawn by Daniel Goossens, Al Coutelis, François Bouck, Gotlib again and Neal Adams.
He is caricaturally chauvinistic and gifted with superpowers that help him to defend his country against a secret terrorist organisation called "Anti-France".
Anti-France agents are all foreigners and thus speak the fictional language "Anti-Français", a mishmash of English, Spanish, Italian, Russian, and German.
The physical appearance of Superdupont is a superhero version of a caricatural Frenchman (specially, as seen by the Anglophone world): he wears a beret, a striped jersey, slippers, a tricolour belt held by a safety pin, a long blue cape.
He also supports economic patriotism, as he smokes Gauloises cigarettes, drinks red wine, eats French cheese and refuses to be painted using China ink.
