Fantasio is a fictional character from the Spirou et Fantasio comic strip. He was introduced in 1944 by Jijé, who was then drawing Spirou's adventures, and quickly became the secondary main character of the series. Fantasio is Spirou's best friend and co-adventurer, a graphic reporter with an uncontrolled imagination and a mop of blond hair. In his early incarnation, he was considerably taller than Spirou, with a clown-like demeanour, and his hairstyle resembled that of Blondie character Dagwood Bumstead. In the Franquin era, his and Spirou's heights began approaching. He has an evil megalomaniac cousin, Zantafio, who is his sworn enemy but bears a strong physical resemblance to him.
