Spirou et Fantasio
Spirou of "Spirou et Fantasio" was a fairly major supporting character in the comic's very early days, though his role was quickly reduced to occasional appearances. He was on generally friendly terms with Gaston, sometimes trying to mediate between him and Fantasio, usually without much success. Like Fantasio, he vanished entirely from the comic when Franquin stopped drawing "Spirou et Fantasio".
